Abstract

The utility model provides a waste treatment device, it is used for carrying out the automatic implementation letter sorting processing after broken to the discarded object. The crushing and sorting machine 18 crushes the waste 12 by the rotation of the blades 52, thereby removing the kitchen waste 22 and throwing the remaining crushed waste 32 obliquely upward from the discharge port 58. Since the air-holding time in the housing portion 64 of the duct 24 is long, the crushed garbage 32 is decomposed and dried in a lump form by the wind generated by the blades 52. When falling from the inner surface of the housing portion 64 toward the drying portion 66 by gravity, the crushed garbage 32 falls while being decomposed by the wind generated by the blades 52. Then, the conveyor 27 can easily separate the lightweight packing material from the heavy solid matter by wind force. The garbage can be automatically sorted according to kitchen garbage, packaging materials and weight solids and then taken out.

[ Prior Art document ]

[ patent document 1 ] WO2013/027402 publication

[ patent document 2 ] patent No. 4282551

[ patent document 3 ] patent No. 5765911

In the waste, packaging material, kitchen waste, metal pieces and other solids are mixed. Patent document 1 describes a technique of crushing and stirring the mixture with a rotary blade to separate the garbage. The residual packaging material and solid matter are dried and then blown away by an air blower, so that the purpose of separating the packaging material is achieved. However, the food waste with moisture adheres to the packaging material immediately after the food waste is separated, and the packaging material itself has a block-like structure. At this time, the packaging material cannot be completely separated unless it is taken out to another facility and dried. Therefore, conventionally, the remaining crushed garbage from which the garbage has been taken out is transferred to another garbage disposal line for subsequent disposal.

In view of the above circumstances, an object of the present invention is to provide a waste treatment apparatus capable of continuously and automatically sorting waste such as household waste into kitchen waste, packaging material, and solid matter by weight.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail by way of examples.

[ example 1 ]

As shown in fig. 1, the waste treatment apparatus includes a crushing and sorting machine 18 and a conveyor belt 27. The housing 38 and a portion of the attachment means surrounding the conveyor belt 27 are indicated by dashed lines. Inside the casing 38, only the conveyor belt 27 is indicated with solid lines. As shown in fig. 5, the waste 12 includes: kitchen waste 22, packaging material 34, and other solids 36 of metal, glass, and ceramic chips. The waste 12 fed from the inlet 42 shown at the right end of fig. 1 is automatically sorted by the waste treatment apparatus according to the kitchen waste 22, the packing material 34, and the solid materials 36 such as other metals, glass, and pottery chips.

The kitchen waste 22 is discharged into the kitchen waste disposal container 30 and processed into, for example, manure of livestock or the like. The packing material 34 is discharged into the packing material processing container 31 and processed into, for example, solid fuel or the like. Solids 36 are discharged into solids processing vessel 28 and the metals contained in solids 36 are sent to a recycling facility. The garbage disposal container 30, the solid material disposal container 28, and the packing material disposal container 31 are, for example, transport containers for transporting to their respective processing plants.

The entirety of the crushing and sifting machine 18 is surrounded by an outer wall 60. The waste 12 introduced from the inlet 42 is sent in the direction of the arrow E in fig. 1. The blade 52 crushes and stirs the waste 12 after input, and sends the waste 12 from the upstream side to the downstream side of the crushing and sorting machine 18. The blade 52 is fixed to the rotary shaft 48 parallel to the direction of the arrow E in the figure. One end of the rotary shaft 48 is disposed upstream of the crushing and sorting machine 18, and the other end thereof is disposed downstream thereof, and supports and rotates the vanes 52.

A structure for conveying the waste 12 from the upstream side to the downstream side will be described with reference to fig. 3 to 6. In fig. 3, the duct 24 (fig. 1) is not shown, and the shape and arrangement of the rectifying plate 44 are shown in a manner easy to understand. Fig. 5 is a cross-sectional view of the crushing and sifting machine 18 located near the arrow 80 in fig. 3. Fig. 6 is a view of the flow straightening plate 44, the vane 52, and the duct 24 as viewed from above with the outer wall 60 removed. The outer wall 60 is indicated in the figure by a dashed line.

As shown in fig. 4, the blade 52 is formed by, for example, fixing four elongated plates to the rotary shaft 48 in a cross-sectional shape. The number of the plates can be three or five.

As shown in fig. 6, the plurality of current plates 44 are arranged at oblique angles with respect to the longitudinal direction of the rotating shaft 48. As shown in fig. 5 and 6, the crushed waste 32 crushed by the rotation of the blades 52 in the direction of the arrow M is sent in the direction of the arrow E while spirally surrounding the rotation shaft 48. As a result, the crushed waste 32 is thrown from the discharge port 58 disposed on the most downstream side of the outer wall 60 toward the duct 24 in the direction of the arrow R.

As shown in fig. 5, a perforated plate 50 is disposed below the crushing and sorting machine 18. The perforated plate 50 filters and separates the fluid kitchen waste 22 contained in the waste 12 crushed by the rotating blades 52. The waste 12 (fig. 1) is usually contained in a plastic or paper packaging material 34 and then is input from an input port 42.

The blade 52 and the projection 46 (fig. 6) knock against the packaging material 34 to tear it apart. The projection 46 is a metal sheet fixed inside the outer wall 60. The protrusion 46 is shaped as illustrated in fig. 5 and 6. The perforated plate 50 is disposed in a region between the upstream side and the downstream side of the waste 12, and is made of a metal mesh, a punching metal, or the like.

Furthermore, the broken waste 32 thrown out to the duct 24 falls down on the conveyor belt 27 (fig. 1). Wind is blown by the blower 25 and the blower 26 to the crushed garbage 32 on the conveyor belt 27, thereby separating the light-weight packing material 34 from the crushed garbage 32. The conveyor belt 27 conveys the crushed refuse 32 placed thereon in the direction of arrow J. The solid material 36 falls in the direction of the arrow K and is stored in the solid material processing container 28.

As shown in fig. 1, the

fans

25 and 26 disposed on the wall of the casing 38 and the lower end of the duct 24 blow air in the direction opposite to the arrow J. Inside the casing 38, the wind always circulates in the opposite direction to said arrow J. Thus, the light-weight packing material 34 is sent in the direction opposite to arrow J by the wind force, falls in the direction of arrow H, and is stored in the packing material processing container 31.

As shown in fig. 2, a discharge port 58 is provided at the downstream end of the outer wall 60. The conduit 24 is arranged in such a way as to surround said discharge opening 58. The conduit 24 is indicated by dashed lines. The duct 24 has: a function of dropping the crushed garbage 32 thrown out of the discharge port 58 by the rotating blades 52 by gravity after receiving it.

Fig. 7 is a cross-sectional view illustrating a main part of the discharge port 58 and the duct 24 of the waste treatment apparatus according to the present invention. Fig. 8 is a cross-sectional view of the periphery of the discharge port of the crushed garbage 32 of the same type of apparatus known in patent document 1 and the like.

As shown in fig. 7, the discharge opening 58 is shaped as an opening extending from the uppermost portion 63 of the outer wall 60 around the wrapping blade 52 to the side. The crushed waste 32 is thrown obliquely upward (in the direction of arrow B). The discharge port 58 blows wind generated by the rotation of the blade 52 not only above the outer wall 60 but also to the side. Thus, the discharge opening 58 extends from the uppermost portion 63 of the outer wall 60 to the side.

As shown in fig. 7, the discharge port 58 is preferably shaped to have an opening extending from the uppermost portion 63 of the outer wall 60 toward the side surface at an opening angle in the range of 60 to 120 degrees when viewed in a cross section perpendicular to the rotation axis 48 of the vane 52. The open state of the outer wall 60 is shown in fig. 9. The opening angle α of the outer wall 60 is preferably in the range of 60 degrees to 120 degrees. If the opening is to the right of the uppermost portion 63 of the outer wall 60, the crushed waste 32 will fly straight up and will be caused to return to the interior of the apparatus after the crushed waste 32 has fallen. In addition, if the opening angle of the side opening exceeds 120 degrees, large pieces of crushed garbage 32 are thrown directly from the side.

The duct 24 is provided with a housing portion 64 at an upper portion thereof and a drying portion 66 at a lower portion thereof. The storage portion 64 is a portion for temporarily retaining the wet crushed waste 32 thrown obliquely upward from the discharge port 58 after being hit. The drying unit 66 is a portion for drying the crushed refuse 32 falling from the storage unit 64 by gravity with the air blown from the discharge port 58.

The effects of fig. 7 and 8 will be described in further detail while comparing them.

As shown in fig. 8, conventionally, the crushed refuse 32 is thrown out in the direction of arrow S from an opening provided in a side surface of an outer wall 60 of the apparatus by the rotational force of a blade 52. At this time, almost all of the crushed garbage 32 having moisture or a small amount of the kitchen garbage 22 adhered to the surface thereof and having a lump shape falls downward in the large lump shape. Therefore, if the crushed garbage 32 is not carried out to the subsequent step and sufficiently dried to decompose the lump form, it becomes difficult to separate the packing material 34 from the other solid materials 36. Therefore, the subsequent process takes time, and the equipment becomes large. Since the crushed garbage 32 is carried out, odor is diffused and the periphery of the device is easily soiled.

As shown in fig. 7, most of the crushed garbage 32 in the present invention is thrown by centrifugal force from the discharge port 58 toward the receiving portion 64 of the upper duct 24. The crushed garbage 32 collides with the upper wall and the inner wall of the receiving portion 64 of the duct 24, but the distance from the blade 52 to the receiving portion 64 is long, and the block-shaped crushed garbage 32 is in a small block-shaped form due to the resistance of the wind when it flies upward. At the same time, the air blown out from the outlet 58 is dispersed and hits the inner wall of the housing portion 64.

The crushed garbage 32 adheres to the inner wall of the storage portion 64 and temporarily stays therein. The crushed waste 32 then falls in a smaller lump when falling due to gravity. When the water falls down to the drying section 66, the water is subjected to wind generated by the rotation of the blades 52, and thus the massive form is further decomposed by the wind force and dried. Thus, the packing material 34 contained in the crushed garbage 32 falling on the conveyor belt 27 shown in fig. 1 is easily blown away by the wind force circulating in the housing 38.

Therefore, even if the broken waste 32 is not conveyed from the waste treatment apparatus, the kitchen waste 22, the packing material 34, and the solid materials 36 such as other metals, glass, and pottery chips can be automatically sorted in the housing 38.

As shown in fig. 1, an exhaust pipe 74 is connected to the casing 38, and the exhaust pipe 74 is used to suck out odor from the inside of the apparatus and treat the odor. Since the configuration of the deodorizing device for treating the odor is a known configuration, the description thereof will be omitted. The interior of the casing 38 is made negative pressure by the action of the odor sucked out from the exhaust pipe 74. Further, since the entire waste treatment apparatus is covered with the outer wall 60 and the cover 38, odor does not leak to the periphery of the apparatus.

As described above, the duct 24 is extended upward from the conventional one, and the wet crushed garbage 32 which is likely to become a lump is thrown upward and then dropped for a long distance, so that the lump crushed garbage 32 is dried as soon as possible after being reduced in size.

Further, even the inlet 42 for inputting the waste 12 causes a problem. If the inlet 42 is disposed at the uppermost portion of the outer wall 60, the rotation of the blade 52 may cause fragments of the waste 12 that have been introduced to fly upward of the outer wall 60, thereby staining the ceiling and the periphery of the apparatus. This causes a new problem of malodor and contamination of the working environment.

Therefore, as shown in fig. 1 and 10, a structure is adopted in which the gabion 72 can be placed on the inlet 42 in an inverted state. As shown in fig. 1, the inlet 42 is disposed on the same side surface as the discharge port 58 avoiding the uppermost portion of the outer wall 60.

As shown in fig. 10 and 11, an opening/closing mechanism 41 is provided at the inlet 42 for inputting the waste 12, the opening/closing mechanism automatically opening and closing the lid 43 when the basket 72 for storing the waste 12 approaches. For example, the cover 43 is opened by winding a chain and returned by an elastic force, or opened and closed by hydraulic or pneumatic force.

The inlet 42 is formed in an opening that is covered when the basket 72 is turned upside down for introducing the waste 12. That is, when the inlet 42 is covered with the basket 72, the waste 12 falls into the crushing and sorting machine 18. As shown in fig. 10, the waste 12 is immediately sent downward after the blades 52 rotate in the direction of arrow M. Since the uppermost portion of the outer wall 60 is not open, fragments of the waste 12 do not fly outwardly. Further, since the inlet 42 is covered when the basket 72 is turned upside down, the odor is not diffused to the outside.

Fig. 12 is a general front view of the entire device after only the cover 38 is shown in broken lines. As shown in the drawing, the packing material 34 contained in the crushed garbage 32 dropped from the duct 24 onto the conveyor 27 is blown to the right by the two

blowers

25 and 26 and is stored in the packing material processing container 31. The solid material 36 conveyed to the left by the conveyor 27 is accommodated in the solid material processing container 28.

If the magnet 33 is disposed between the end of the conveyor 27 and the solid material processing container 28, when the solid material 36 falls from the conveyor 27 into the solid material processing container 28, the metal receiving the magnetic force falls into the basket on the right side of the solid material processing container 28. In this way, the metal piece can be separated from the pottery piece or the like. Further, a mechanism for compressing the contents may be built in the garbage disposal container 30 and the packaging material disposal container 31. In this way, a device that takes into account the working environment can be realized as a whole.
