Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

That is, as shown in FIGS. 1 to 9, the automatic cleaning filter device 20 for a pipe according to the present invention is connected to a pipe through which a fluid flows, filters foreign matter mixed with the fluid in the pipe, To the outside of the pipe to remove foreign matter from the pipe. Particularly, after the foreign object has been filtered to a predetermined extent, the foreign object is automatically discharged, so that the foreign matter is not necessarily discharged.

The filtering technology of the present invention includes a filter for filtering out foreign matter, a structure for discharging foreign matter by a predetermined amount of foreign matter, and the like, which is disclosed in Korean Utility Model No. 20-1999-013250 The techniques disclosed by the present invention can be mainly used. Hereinafter, the operation configuration of the present invention will be described with reference to the public utility model No. 20-1999-013250.

That is, according to the above-mentioned design, the lower filter is moved upward by the spring at the lower outlet side in the normal state, and the fluid flows while flowing from the outside of the lower filter to the inside.

In this case, foreign matter is filtered out of the filter, and the outside of the filter is clogged by the foreign matter to some extent, which obstructs the fluid flow. Then, when the valve on the discharge side is opened, the foreign material on the outside of the filter is discharged through the valve, so that the internal differential pressure moves the filter sleeve downward and blocks the flow to the outside of the filter.

Further, the guide barrel on the upper side of the filter also moves downward, and the fluid flows into the inflow hole. The fluid thus introduced flows into the filter, passes through the filter, and is discharged to the lower outlet. As a result, the foreign matter on the outer surface of the filter is discharged by the flow of the fluid, so that the foreign matter need not be separately cleaned.

In such a design, the user must open and close the following valve.

Accordingly, in the present invention, the foreign substance is automatically opened and closed by the filtering device to smoothly discharge foreign matter.

Hereinafter, the detailed construction of the automatic cleaning filter apparatus 20 for piping according to the present invention will be described.

A cleaning filter device connected to a pipeline to remove foreign substances is provided with a chamber body (21) connected to a pipe through which a fluid flows. A foreign substance contained in the fluid flowing in the chamber body (21) is removed A filter 22 is provided.

A foreign matter discharging portion 23 for removing the foreign matters filtered by the filter 22 is provided. The foreign matter discharging unit 23 is provided with a structure for interrupting the flow of fluids and foreign substances, and can be configured in the same manner as a general valve, and a detailed description thereof will be omitted.

And a discharge operation part 24 for opening and closing the foreign matter discharge part 23 for discharging foreign matter through the foreign matter discharge part 23 is provided.

The discharge operation part 24 is a solenoid type device operated by an electrical signal according to a control signal and is configured to be operated to open and close the foreign matter discharge part 23. The electronic device for such valve operation is a solenoid- Valve operation, and a detailed description thereof will be omitted.

As an example of the application of the above-described design, foreign matter flowing together with the fluid by the filter 22 is filtered out of the filter 22, and the flows of the inflow side and the outflow side of the fluid are different from each other The discharge operation portion 24 is operated to open the foreign matter discharge portion 23. Thus, the foreign matter filtered outside the filter 22 is discharged to the foreign matter discharging portion 23. In addition, as in the conventional example, when a spring, a guide, or the like is provided to block the flow of the fluid to the outside of the filter while flowing the fluid to the inside of the filter, the fluid flows out from the inside of the filter to the outside, So that foreign matter outside the filter can be also discharged.

In the cleaning filter device 20 according to the present invention as described above, the discharge operation part 24 is controlled to be operated by sensing the flow of the fluid on the inflow side and the outflow side and comparing the set value with the set value, .

As a method for sensing the fluid flowing through the sensor, a fluid pressure sensing technique described below, a flow sensing technique based on the flow of the fluid, or the like, may be used, and a technique for sensing the flow of the fluid may be used . Hereinafter, a detailed description will be made with reference to an example in which a pressure sensing technique according to a flow of a fluid, and a flow sensing technique according to a flow of a fluid are applied.

First, the description will be made by taking the technique of sensing the pressure of the fluid generated according to the fluid flow on the inflow side and the inflow side, respectively, and applying the same.

The inlet pressure sensing unit 25 senses the inflow pressure of the inflow fluid, which is installed in the inflow pipe 11 flowing into the chamber body 21.

And an outlet pressure sensing unit 26 for sensing the outlet pressure of the fluid flowing out of the chamber body 21.

The filter controller 30 of the cleaning filter device 20 receives the sensing data from the inflow pressure sensing unit 25 and the outflow pressure sensing unit 27 and receives a sensed pressure difference between the inflow pressure and the inflow pressure And operates the discharge operation part 24 when the difference is equal to or greater than a predetermined set pressure.

That is, the filter controller 30 compares the pressures of the fluid sensed by the inflow pressure sensing unit 25, the outflow pressure sensing unit 26, and the like with each other. Then, the outflow side pressure is significantly different from the set value A control signal for discharging the foreign matter is transmitted to the discharge operation part 24. [ Thus, the discharge operation portion 24 is operated to open the foreign body discharge portion 23 to discharge the foreign substance.

Next, the description will be made by taking the technique of sensing the flow rate of the fluid generated according to the fluid flow on the inflow side and the inflow side, respectively, and applying the same.

As described above with respect to the cleaning filter device 20 according to the present invention, a cleaning filter device connected to a pipe to remove foreign substances is provided with a chamber body 21 connected to a pipe through which a fluid flows, A filter 22 for removing foreign substances contained in the flowing fluid, a foreign matter discharging part 23 for removing foreign matters filtered by the filter, and a foreign matter discharging part 23 for discharging foreign matter through the foreign matter discharging part 23 23 for opening and closing the discharge operation portion 24 and the like will be applied as they are.

An inflow flow sensing part 27 installed in the inflow pipe 11 flowing into the chamber body 21 for sensing inflow flow rate of the inflowing fluid and an outflow flow rate of the fluid flowing out from the chamber body 21, And an outflow flow sensing unit 28 for sensing the flow.

The filter controller 30 of the cleaning filter device 20 according to the present invention receives the sensing data from the inflow flow sensing unit 27 and the outflow sensing unit 28 and compares the influent flow rate and outflow flow rate of the fluid And operates the discharge operation part 24 when the outflow flow rate differs by more than the predetermined set flow rate with respect to the inflow flow rate.

That is, the filter controller 30 compares the flow rates of the sensed fluids from the influent flow sensing unit 27, the outflow flow sensing unit 28, etc., and then determines whether the flow rate on the outflow side is significantly different from the set value A control signal for discharging the foreign matter is transmitted to the discharge operation part 24. [ Thus, the discharge operation portion 24 is operated to open the foreign body discharge portion 23 to discharge the foreign substance. In the example of FIG. 6, an example of a technique of measuring the flow rate by applying the ultrasonic technique is shown. In FIG. 6 (a), the speed of the discharged flow rate is slow due to a large amount of foreign matter. This is an example of a state in which the flow rate of discharged water due to the removal of foreign matter is fast.

FIG. 7 shows an example of the flow rate display unit 35 as a ramp so that the set value for the flow rate of the flowing fluid can be known.

An example of such a case of FIG. 7 will be described with reference to an example in which a flow rate of 1 L per minute is set when one of the illuminated lamps is turned on. Thus, in FIG. 7 (a), a total of six lamps are turned on, so that a pipeline structure having a flow rate of 6 L per minute is shown.

In FIG. 7 (b), a total of four lamps are turned on to show an example of a pipe structure in which a flow of 4 L per minute is applied. Further, FIG. 7C shows an embodiment of a piping structure in which a total of one lamp is turned on and a flow of 1 L per minute is applied.

Next, the detailed configuration of the filter controller 30 for sensing and comparing and discriminating the pressure or the flow rate according to the flow of the fluid as described above and discharging foreign matter as a result will be described.

That is, the filter controller 30 includes a device data storage unit 31 for storing at least one of a pressure and a flow rate of a fluid flowing in and out, and storing setting data of the cleaning filter device 20.

In the detailed configuration of the data storage unit 31, a setting data storage unit 311 for storing setting data of the cleaning filter unit 20 is provided. That is, basic setting data for each member in association with fluid flow and foreign matter filtering, and data of a control configuration for operation of the controller or discrimination.

In addition, predetermined set pressure data for a difference to be applied in the comparison determination of the inlet inflow pressure of the fluid and the outlet-side outlet pressure of the fluid are stored.

The predetermined set flow rate data for the difference to be applied in the comparison determination of the inflow-side inflow-side flow rate and the outflow-side inflow-side flow rate of the fluid are stored. When the flow rate of the flowing fluid is measured by using the ultrasonic technology, the control configuration of the ultrasonic wave oscillation part, the control configuration of the ultrasonic wave reception part, and the configuration of the flow rate, oscillation part, and receiver part may be stored.

The data of the inflow pressure of the fluid sensed by the inflow pressure sensing unit 24, the data of the outflow pressure of the fluid sensed by the outflow pressure sensing unit 25, the data of the fluid sensed by the inflow flow sensing unit 27, And a sensed data storage unit 312 for sensing data including data of an outflow flow rate of the fluid sensed by the outflow sensing unit 28. Thus, the numerical values of the pressure and flow rate discrimination on the inflow side and the outflow side of the fluid are stored, and when the difference value is compared with the set data value, the data such as the calculated value will be stored.

And a pressure sensing discrimination unit 32 for calculating a difference value of the outflow pressure flowing out of the inflowing pressure of the fluid and comparing it with a predetermined set pressure stored in the device data storage unit 31. By comparing the inflow pressure with the predetermined set pressure data stored in the device data storage unit 31 with respect to the inflow pressure at which the fluid is introduced by the comparison determination process by the pressure sensing discrimination unit 32, , The abnormal state is generated and information of the abnormal state is generated.

Therefore, the numerical data such as the inflow pressure, the outflow pressure, and the predetermined set pressure according to the flow of the piping and the fluid to be combined in the operation of the cleaning filter device 20 according to the present invention are not limited to the piping equipment, It will be operated according to the scale of the facilities and degree of use, and an example will be omitted.

And a flow sensing discrimination unit 33 for calculating a difference value of the outflow flow rate flowing out from the inflowing flow quantity of the fluid and compares it with a preset flow rate stored in the device data storage unit 31 .

The outflow flow rate flowing out of the fluid flowing in by the comparison determination process by the flow sensing discrimination unit 33 is compared with the predetermined flow rate data stored in the device data storage unit 31, If it is determined that the abnormality has occurred, the abnormal state is generated and information of the abnormal state is generated.

Accordingly, the numerical data such as the inflow flow rate, the outflow flow rate, and the predetermined flow rate depending on the piping and the fluid flowing in the operation of the cleaning filter device 20 according to the present invention are not limited to the piping equipment, It will be operated according to the scale of the facilities and degree of use, and an example will be omitted.

If the difference between the pressure or flow rate on the inflow side and the inflow side of the fluid differs by more than the set value by the pressure sensing discrimination unit 32 or the flow sensing discrimination unit 33, And a valve opening / closing operation control unit (36) for transmitting a control signal to the operation unit (24) and causing the discharge operation unit (24) to discharge foreign substances through the foreign matter discharge unit (23).

The inflow pressure sensing unit 25 and the outflow pressure sensing unit 26 are connected to each other while the foreign substances are discharged through the foreign matter discharging unit 23 by the operation of the discharging operation unit 24 under the control of the valve opening / The flow limitation sensing unit 27 and the outflow flow sensing unit 28 and excludes the sensing data from being stored in the device data storage unit 31. [ That is, during the discharge of foreign matter by the operation of the discharge operation part 24, there is almost no flow of the fluid to the outlet side, so that the oil pressure and the flow rate at the outlet side will not be sensed. , The abnormality occurrence is continuously determined. Therefore, in order to prevent this, the data collected from each sensor is excluded from the discrimination while the foreign substance is discharged.

According to the filter controller 30 according to the present invention thus prepared, the following process is performed.

First, as described above, the filter controller 30 receives sensing data from the inflow pressure sensing unit 25 and the outflow pressure sensing unit 27 and receives a sensed pressure difference between the inflow pressure of the fluid and the outflow pressure, Which is a process of determining the flow-out fluid pressure.

The filter controller 30 receives sensing data from the inflow flow sensing unit 27 and the outflow flow sensing unit 28 and compares the influent flow rate and outflow flow rate of the fluid to determine the outflow flow rate with respect to the inflow flow rate, Which is a process for determining the flow rate of the inflowing fluid to be compared with the flow rate.

The filter controller 30 performs the flow rate discrimination process or the flow rate discrimination process so that the flow rate of the fluid can be detected by the pressure sensing discrimination unit 32 or the flow rate sensing discrimination unit 33 on the inflow side and the outflow side When the difference in pressure or flow rate is different from the set value or more, a control signal is transmitted to the discharge operation part 24 to discharge the foreign matter through the foreign matter discharge part 23 by the operation of the discharge operation part 24 And performs a control process as a control process.

The filter controller 30 controls the operation of the inlet pressure sensing unit 25 and the outflow pressure sensing unit 25 while foreign substances are discharged through the foreign matter discharge unit 23 by the operation of the discharge operation unit 24 under the control of the valve opening / A control process of a measurement limit control process in which sensing data transmitted from the pressure sensing unit 26, the inflow flow sensing unit 27, and the outflow flow sensing unit 28 are excluded and stored in the device data storage unit 31 is excluded .

The filter controller 30 determines whether there is no pressure in sensing the sensing data of the inflow pressure received from the inflow pressure sensing unit 25 or the sensed data of the inflow flow received from the inflow sensing unit 27 The flow of the fluid supply abnormality which generates an abnormality signal exceeding the fluid supply is performed in the control process of the fluid supply abnormality generation process.

The filter controller 30 senses the inflow pressure received from the inflow pressure sensing unit 25 and senses the inflow flow rate received from the inflow flow sensing unit 27 to be transmitted from the outflow pressure sensing unit 26 When it is determined that no pressure is generated in determining the sensing data of the received flow pressure or when it is determined that there is no flow rate in determining sensed data of the influent flow transmitted from the flow sensing unit 28, And a process of controlling the abnormal sending process of the filter device for generating a signal.

[ In other words, in the control data storage unit 101, information collected from the respective cleaning filter devices 20 is stored. As information of flow of the fluid, comparison information of the inflow side and inflow side pressure and flow rate of the fluid, Information on the discharge period of the filtered foreign substances, and the like. Such information is provided to the manager, and if necessary, when abnormal information of each valve device is sensed, the alarm is generated in response to the abnormality, so that the alarm occurrence information is also stored.

Next, the cleaning filter control system 100 analyzes the data received from one or more of the cleaning filter devices 20, and analyzes data on inflow pressure, outflow pressure, inflow flow rate, and outflow flow rate of the fluid measured over time And a sensing data analysis unit 102 for calculating pattern information of each data.

When the pressure difference between the inflow pressure and the inflow pressure of the fluid in the cleaning filter device 20 is greater than a predetermined set pressure or the flow rate difference between the inflow flow rate and the outflow flow rate of the fluid is greater than a predetermined set flow rate And an abnormal symptom discrimination unit 103 for discriminating an abnormal phenomenon when it is determined that the abnormality has occurred.

In addition, the cleaning filter control system (100) is provided with a cleaning filter device (20) which is determined as an abnormal phenomenon by the abnormality symptom determination part (103) And an abnormal state notification unit 104 for storing the abnormal state information in the data storage unit 101 and transmitting abnormal state information to a terminal of a predetermined administrator.
