Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the embodiment of the present invention discloses a clean room 100, wherein the clean room 100 can be assembled and disposed in a processing workshop, the processing workshop can provide a better protection effect for the clean room 100, and the clean room 100 can provide a production space with high cleanliness for the processing workshop. The clean room 100 includes a chamber body 110 and a plurality of filtering devices 120, and the clean room 100 further includes a humidifier (not shown), a curtain fan 150, and the like, which will be described later. In addition, the clean room 100 may be further provided with a purge lamp panel 160, a thermometer, a hygrometer (none of which are shown), and the like. Of course, the chamber body 110 is provided with an inlet, and a door may be provided at the inlet, and a worker may enter the clean room 100 by opening the door to perform a production work.

Among them, as shown in fig. 1 and 2, the purge lamp tray 160 may be installed at the top of the chamber body 100 in the clean room 100, thereby ensuring that the purge lamp tray 160 can provide a good illumination effect for the inside of the clean room 100. The number of the purge lamp trays 160 may be one, in which case the purge lamp trays 160 may be installed in a central region of the ceiling in the clean room 100. Alternatively, the number of the purification lamp trays 160 may be plural, and in the case where the number of the purification lamp trays 160 is plural, the plural purification lamp trays 160 are dispersed and spaced apart to provide a better illumination effect for the clean room 100.

The thermometer and hygrometer may be directly installed in the chamber body 110 of the clean room 100 to monitor the temperature and humidity inside the chamber body 110, so that the worker can adjust the temperature and humidity inside the clean room 100 according to the readings of the thermometer and hygrometer. The purpose of adjusting the temperature in the clean room 100 can be achieved by adjusting the preset temperature of the air conditioning system of the processing workshop, and the humidity in the clean room 100 can be adjusted by adjusting the humidifier arranged in the clean room 100, so that the temperature and the humidity in the clean room 100 can meet the working requirements. The humidifier may be a finished humidifier, and may be placed on the bottom surface of the chamber body 110, such that the moisture generated by the humidifier can be diffused in the clean room 100 as the gas circulates inside the clean room 100 and outside the clean room 100, thereby making the humidity at any position in the clean room 100 substantially the same and making the working environment in the clean room 100 more comfortable.

The chamber body 110 is assembled by a plate material, and it is ensured that the sealing performance of the chamber body 100 is better, so that the cleanliness in the clean room 100 is higher by the plurality of filtering devices 120 during the use of the clean room 100, thereby satisfying the high-cleanliness production requirement. The plate may be a metal plate such as a steel plate, or a combined plate such as a fine core plate. Optionally, the plate is a glass magnesium plate double-sided baking varnish color plate, which makes the flatness and structural strength of the chamber body 110 relatively higher, and may improve the fire resistance of the clean room 100. The chamber body 110 may be a cubic structure, which may be formed by splicing a plurality of plates, and the thickness of each plate may be determined according to actual conditions. Alternatively, the thickness of the sheet material may be 50 mm. Under the condition that the boards adopt the glass magnesium board double-sided baking finish color steel plates, any adjacent boards can be mutually assembled and connected through a bayonet structure, so that the disassembly and assembly difficulty of the clean room 100 is smaller. In addition, the sealing performance between the plates can be further improved by filling sealant in the gaps between the plates and the like.

The filtering device 120 is an air filter, and the structures of the filtering devices 120 can be the same, so as to reduce the difficulty of spare parts. The plurality of filtering devices 120 may be all FFU (Fan Filter Unit, Fan filtering device 120) purifiers, which may ensure that the filtering device 120 has higher filtering efficiency and filtering effect. The plurality of filtering devices 120 are all installed on the chamber body 110, and may be specifically installed on at least one of the top, the side 111, and the bottom 112 of the chamber body 110, so that the gas introduced into the chamber body 110 can be filtered by the filtering devices 120, and the cleanliness of the gas introduced into the chamber body 110 is improved. The plurality of filtering devices 120 may be uniformly distributed on the chamber body 110 at intervals, so that the plurality of filtering devices 120 may be more dispersedly disposed on the chamber body 110, and therefore, a relatively clean gas may be introduced into any position of the chamber body 110, and the cleanliness of the gas in the entire chamber body 110 is relatively high. The specific number of the filter devices 120 may be determined according to specific parameters such as the ventilation volume of the chamber body 110.

At least one filter apparatus 120 of the plurality of filter apparatuses 120 is in communication with an air conditioning system of the process plant. Specifically, the filtering device 120 may communicate with an air outlet of the air conditioning system in the process plant through a closed duct, so that cool air generated from the air conditioning system in the process plant can be introduced into the clean room 100 after being filtered. In this case, there is no need to separately fit an air conditioning system to the clean room 100, which can reduce the overall cost of the clean room 100 on the one hand and also reduce the design and assembly difficulty of the clean room 100 to some extent on the other hand. The specific number of the filtering devices 120, which are connected to each other with the air conditioning system of the process plant, may be flexibly adjusted according to parameters such as a general temperature of the air conditioning system and a temperature requirement of the clean room 100. More specifically, only one of the plurality of filter devices 120 may be in communication with the air conditioning system, while the other filter devices 120 may be in communication with the large environment of the process plant; alternatively, each filter device 120 may be in communication with an air conditioning system.

The embodiment of the application discloses a clean room 100, wherein a chamber body 110 is composed of a plate material, the sealing performance is higher, and the cleanliness in the clean room 100 is relatively higher by virtue of a filtering device 120. Meanwhile, at least one of the plurality of filtering devices 120 is communicated with an air conditioning system of the process shop, so that the cost of the clean room 100 can be reduced, and the design and assembly difficulty of the clean room 100 can be reduced.

Further, the chamber body 110 includes a top, a side 111 and a bottom 112, the top, the side 111 and the bottom 112 may be formed by a single plate, or may be formed by splicing a plurality of plates, and the overall size of the chamber body 110 may be flexibly selected according to actual requirements, and is not limited herein. Wherein the side 111 is supported on the floor 300 of the process plant to provide a supporting and fixing function for the whole clean room 100. Specifically, a sink may be formed on the floor 300 of the process plant, and the side portion 111 may be extended into the sink to ensure that the chamber body 110 and the floor 300 of the process plant form a stable fixed relationship. Alternatively, the side 111 of the chamber body 110 may be fixedly coupled to the floor 300 by means of a coupling member such as an expansion screw, thereby further improving the reliability of the fixed relationship between the chamber body 110 and the floor 300 of the process plant.

The top is connected to one end of the side 111, and a plurality of filtering devices 120 may be installed on the top to introduce clean gas into the clean room 100 through the top of the chamber body 110. In this case, even if a small amount of dust or foreign materials are present in the clean room 100, the dust or foreign materials are attached to the bottom 112 of the chamber body 110 by gravity, and the clean gas is introduced through the top, so that the dust or foreign materials are prevented from flying by the airflow, and the cleanliness of the clean room 100 is further improved. In addition, the clean room 100 may be exhausted to the outside of the clean room 100 through any one of the top, side and

bottom portions

111 and 112, thereby ensuring a normal exchange of gas between the inside and outside of the clean room 100.

The bottom portion 112 is connected to the side portion 111 at an end thereof facing away from the top portion such that the bottom portion 112 is spaced apart from the top portion to form a space for performing a machining work. The bottom 112 is spaced from the floor 300 of the processing plant. In this case, the cleanliness control in the clean room 100 is improved by elevating the clean room 100 such that the air in the clean room 100 forms a vertical laminar flow. Specifically, the base 112 and the floor 300 of the process plant may be supported relative to each other by support posts. Or, a steel structure frame body can be installed on the ground 300 of the processing workshop, and the bottom 112 is supported on the steel structure frame body, so that the bottom 112 is guaranteed to have better structural stability. Additionally, the size of the space between the base 112 and the floor 300 of the process plant may be determined based on the circumstances.

Based on the above embodiment, in the case that the filter device 120 is disposed at the top of the chamber body 110, a penetration hole may be formed at the bottom 112 of the chamber body 110, thereby allowing gas to flow from top to bottom within the chamber body 110. In this case, even if dust, foreign materials, or the like exist in the chamber body 110, the dust, foreign materials, or the like may be discharged from the through-holes of the bottom 112 to the outside of the chamber body 110 along with the flow of the gas, thereby further improving the cleanliness in the clean room 100 and preventing the dust or foreign materials from flying in the clean room 100.

Alternatively, the pressure of the gas inside the chamber body 110 may be greater than the pressure of the gas outside the chamber body 110, in which case dust and debris outside the chamber body 110 may be prevented from flowing back into the chamber body 110 through the through-holes of the bottom 112 of the chamber body 110.

Further, an exhaust passage may be formed on the floor 300 of the process plant to ensure that gas can be exhausted from the through-holes of the bottom 112 of the chamber body 110. Alternatively, as shown in fig. 1 and 2, a gas discharge hole 111a may be provided in a portion of the side portion 111 of the chamber body 110 located at the bottom portion 112 away from the top portion, the gas discharge hole 111a communicating with the chamber body 110 through a penetration hole. In this case, it may also be ensured that gas may be exhausted from the chamber body 110 to the outside of the chamber body 110.

Specifically, the bottom 112 may be formed of a single plate, and a through hole is formed in the plate for forming the bottom 112 by drilling or the like. The number of the exhaust holes 111a may be plural, and the plurality of exhaust holes 111a may be uniformly and alternately arranged, so that the size of a single exhaust hole 111a may be reduced, the side portion 111 may have a high structural strength, and the uniformity of the exhaust of the clean room 100 may be relatively good. In the case where the side portion 111 has a rectangular structure, at least one exhaust hole 111a may be provided on any one side surface of the side portion 111. The side 111 is further provided with an observation window 111b, through which the inside of the clean room 100 can be observed, and the worker in the clean room 100 can observe the outside of the clean room 100 through the observation window 111 b.

In another embodiment of the present application, the base 112 may include a plurality of floor panels that are joined to form the base 112, which may reduce the difficulty of machining the base 112. Optionally, the plurality of floor boards are all rectangular structures, and can be connected together in a bonding mode, a clamping mode or a buckling mode. As mentioned above, the ground 300 of the processing workshop can be further provided with a steel structure frame body, and a plurality of floors can be supported on the steel structure frame body, so that the plurality of floors can be stably supported.

Based on the above embodiment, optionally, through holes are provided on some of the plurality of floor boards, that is, no through hole is provided on other floor boards of the plurality of floor boards, so that the structural strength of the entire bottom 112 is relatively high while the bottom 112 is ensured to be able to communicate with the outside of the clean room 100. More specifically, a plurality of regularly distributed through holes can be arranged on one floor, so that the size of each through hole is relatively smaller, and the structural strength of the single floor is further improved. Moreover, the plurality of floors can be arranged in a row-by-row manner, and the floors provided with the through holes and the floors not provided with the through holes are alternately distributed along the row (or the column), so that the ventilation effect of the clean room 100 is further improved, and the overall structural strength of the bottom 112 is relatively high.

In addition, the sum of the flow rates of the through-holes provided throughout the bottom portion 112 may be equal to the intake air amount of the plurality of filter devices 120. Alternatively, the sum of the flow rates through the perforations may be made smaller than the intake air amount of the plurality of filter devices 120, so that the air pressure inside the chamber body 110 is greater than the air pressure outside the chamber body 110. More specifically, the flow rate of the plurality of filter devices 120 and the through holes can be designed such that the bottom 112 is subjected to a positive pressure of about 10pa, thereby ensuring that dust and debris outside the chamber body 110 cannot enter the chamber body 110 through the through holes of the bottom 112.

Further, a water containing box 170 can be arranged on one side, away from the top, of the floor provided with the through hole, and water is contained in the water containing box 170, so that dust, impurities and the like in the chamber main body 110 can be adsorbed and collected in the water containing box 170 in the process of being discharged out of the chamber main body 110 along with gas through the through hole, and the dust, the impurities and the like are prevented from being blown to a processing workshop to pollute the large environment of the processing workshop. Specifically, the size of the water containing box 170 may be comparable to that of the floor, so as to ensure that the air discharged from any position on the floor along with the carried dust and impurities can be adsorbed in the water containing box 170.

Further, the floor may be detachably constructed so that the water bucket 170 can be refilled and the water bucket 170 can be cleaned by detaching the floor after the clean room 100 is used for a certain period of time. Or, the clean room 100 may further include a water pipe 180, so that water may be supplied into the water containing box 170 through the water pipe 180, and meanwhile, dust and foreign materials adsorbed and collected in the water containing box 170 may be taken away, thereby reducing the maintenance workload of the clean room 100 and ensuring that the clean room 100 may always maintain high cleanliness.

As described above, the chamber body 110 is provided with an entrance provided with a door, and optionally, the chamber body 110 is provided with a processing compartment 116, a pre-entry compartment 117, a changing compartment 118, and a shoe cabinet compartment 119. The processing compartment 116, the pre-entrance compartment 117, the dressing compartment 118, and the shoe cabinet compartment 119 are four spaces independent of each other in the chamber body 110. The chamber body 110 serves as an outer structure of the entire clean room 100, and the inside thereof may be partitioned by a plate material, thereby forming the aforementioned four independent spaces.

The processing room 116 has the largest volume, and is used as an area where a worker performs a processing work. The shoe chest 119 is an area where workers change shoes or wear shoe covers after entering the clean room 100 to prevent the shoe soles, to which much dust and sundries are attached, from causing a large contamination of the processing room 116. The changing room 118 provides a working room 116 with a separation function for workers in the area where they change clothes or wear dust-proof clothes, and the pre-entry room 117 further reduces or even prevents dust and foreign materials in the shoe cabinet room 119 and the changing room 118 from entering the working room 116 when workers enter or exit the working room 116. In order to further ensure high cleanliness in the clean room 100, the processing room 116, the pre-entry room 117, the dressing room 118, and the shoe cabinet 119, which are independent of each other, are provided with the filter devices 120, and the number of the filter devices 120 to be provided can be determined according to the sizes of the volumes of the four. Meanwhile, the processing room 116, the pre-entry room 117, the dressing room 118 and the shoe cabinet 119 may be provided with the purification lamp panels 160, and optionally, the purification lamp panels 160 may be provided on opposite sides of any one of the filtering devices 120, so as to further enhance the illumination effect of the whole clean room 100.

Based on the above-described embodiment, the entrance of the entire clean room 100 may be provided at the shoe chest 119, the shoe chest 119 is communicated with the pre-entrance room 117 through the changing room 118, and the changing room 118 is communicated with the processing room 116 through the pre-entrance room 117. That is, in the process of entering the clean room 100, the worker needs to change shoes or wear shoe covers in the shoe chest 119, then enter the changing room 118 through the shoe chest 119, change clothes or wear dust-proof clothes in the changing room 118, then enter the pre-entry room 117, and finally enter the processing room 116 through the pre-entry room 117. In order to ensure that the processing room 116, the pre-entry room 117, the dressing room 118 and the shoe cabinet room 119 are independent and can be communicated with each other, doors may be provided between the shoe cabinet room 119 and the dressing room 118, between the dressing room 118 and the pre-entry room 117, and between the pre-entry room 117 and the processing room 116. The shoe chest 119, the dressing change 118 and the pre-entry room 117 may be sequentially disposed at the edge of the chamber body 110, thereby making the configuration of the processing room 116 more square and improving the accommodation capacity of the processing room 116.

Optionally, a translation door 130 is disposed at an entrance of the shoe cabinet 119, so that in a process of opening and closing the translation door 130, a flow amplitude of air around the translation door 130 is relatively small, and an amount of dust and impurities entering the shoe cabinet 119 when the translation door 130 is opened can be reduced, so as to further improve cleanliness of the clean room 100. The translation door 130 may be made of a metal material. Optionally, the sliding door 130 is made of tempered glass, so that light outside the clean room 100 can pass through the sliding door 130 and enter the shoe cabinet 119, and the illumination effect of the shoe cabinet 119 is improved.

In order to further prevent dust outside the clean room 100 from entering the shoe cabinet room 119 along with the opening and closing of the sliding door 130, as shown in fig. 1, an air curtain machine 150 may be disposed at an entrance of the shoe cabinet room 119, so that the inside and the outside of the shoe cabinet room 119 are isolated from each other by opening the air curtain machine 150 in the process that workers enter and exit the shoe cabinet room 119, and the probability of external dust entering the shoe cabinet room 119 is further reduced. The air curtain machine 150 may be installed above an entrance of the shoe chest 119 and blow down, which may also blow down dust or foreign materials attached to the staff in advance while the staff enters the shoe chest 119.

Further, in case that the shoe cabinet room 119 is provided with an entrance, the processing room 116 may be further provided with a safety escape door 140, and in case that the clean room 100 is normally used, the safety escape door 140 is in a normally closed state to prevent dust and foreign materials from directly entering the processing room 116 through the safety escape door 140 to adversely affect the cleanliness of the processing room 116. Once the clean room 100 is threatened, the safety escape door 140 can be opened, so that the workers working in the processing room 116 can directly leave the processing room 116 through the safety escape door 140, the escape efficiency of the workers is improved, and safety accidents are prevented as much as possible. The safety escape door 140 may be disposed in the side portion 111 of the chamber body 110 at a position opposite to the pre-entry compartment 117, which may ensure a relatively wide escape space around the safety escape door 140 and may further reduce the occupation of more processing space in the processing compartment 116 due to the disposition of the safety escape door 140.
