Description

Technical Field

[0001] This invention relates to coal washing technology, specifically to an intelligent water flow monitoring system for coal washing. Background Technology

[0002] Coal washing separates raw coal of different compositions and specific gravities into different grades by the impact of water flow, and removes dust and waste rock, reducing ash and sulfur content. Coal washing is an essential step in coal processing. Coal after washing is called refined coal. In addition to achieving environmental protection goals, coal washing can also improve the utilization rate of coal.

[0003] In existing technologies, when coal washing operations are carried out in a filtration tank and the filtration speed slows down, affecting the efficiency of coal washing, the filtration process often involves directly cleaning the screen plates to remove blockages. However, when other factors cause the filtration speed to slow down, workers cannot promptly detect and eliminate these adverse factors. Furthermore, the cleaning mechanism can negatively impact the filtration process of the screen plate holes during operation, reducing the coal washing efficiency of the filtration tank. When filter plates used for coal washing become clogged, the unblocking mechanism is often used to unblock the entire surface of the filter plate, which is time-consuming. Moreover, using only a single unblocking method for different types of blockages can negatively impact the screen holes, reducing the accuracy of the screen plates in subsequent coal washing operations.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to compare and analyze the data of factors affecting the filtration rate when the filtration rate is abnormal through a water flow intelligent monitoring component. This allows abnormal filtration rates caused by other factors to be detected in a timely manner and countermeasures to be taken, reducing the adverse impact on the coal washing efficiency of the filtration tank. Subsequently, by comparing and analyzing the data of blockages, the data processing unit can push or pull out the blockages from the upper or lower side of the screen plate based on the analysis results of several units. This reduces the adverse impact on the screen holes on the screen plate during the removal operation and reduces the impact on the accuracy of the coal washing operation on the screen plate. This solves the problem that directly clearing the screen plate when the filtration rate is abnormal causes the coal washing efficiency to slow down, and the single clearing method is prone to screen plate damage. Therefore, an intelligent water flow monitoring system for coal washing is proposed.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The intelligent water flow monitoring system for coal washing includes a filter tank body, a water flow intelligent monitoring component, a computer, and a dredging component. The inner wall of the filter tank body is equipped with a sieve plate body, and the water flow intelligent monitoring component includes a data acquisition unit, a data processing unit, and a data execution unit.

[0008] The data acquisition unit collects the filtration rate detection values, filtration rate influencing factor data, and blockage data, and transmits the collected filtration rate detection values, filtration rate influencing factor data, and blockage data to several other units. The filtration rate influencing factor data includes the water volume in the filter tank, the water turbidity data, and the filtration pressure data. The blockage data includes the blockage size data and the blockage hardness data.

[0009] The system processes the filtration rate detection values, filtration rate influencing factor data, and blockage data transmitted from the data acquisition unit, and generates corresponding execution signals, which are then transmitted to the data execution unit. The execution signals include repair execution signals, stirring execution signals, pressure regulation execution signals, and unblocking execution signals.

[0010] The execution unit receives execution signals from several units and performs corresponding operations.

[0011] As a preferred embodiment of the present invention, the steps for analyzing the water storage data of the filter tank in several units are as follows:

[0012] Step 1: Several units receive the detection values ​​of the filtration rate of the filter screen inside the coal washing tank and the data of the water volume in the filter tank from the data acquisition unit. Then, by calculating the water volume data of the filter tank, the calculated value of the filtration rate under the corresponding water volume data is calculated, and the calculated value of the filtration rate is compared with the detected value of the filtration rate.

[0013] Step 2: If the calculated filtration rate corresponding to the water volume is greater than the detected filtration rate, the filter tank damage condition is checked. If the filter tank is determined to be undamaged, a blockage judgment signal 1 is generated, and the water flow turbidity data is analyzed. If the filter tank is determined to be damaged, a repair execution signal 1 is generated. If the calculated filtration rate corresponding to the water volume is equal to the detected filtration rate and there is no abnormality, the process jumps to the analysis of water flow turbidity data. If the calculated filtration rate corresponding to the water volume is less than the detected filtration rate, the filter plate is determined to be damaged, a repair judgment signal 1 is generated, and the process jumps to the analysis of water flow turbidity data.

[0014] As a preferred embodiment of the present invention, the steps for analyzing water turbidity data at several units are as follows:

[0015] Step 1: Several units receive the filtration velocity detection value and water turbidity data of the filter screen inside the coal washing pool from the data acquisition unit. Then, by calculating the water turbidity data, the filtration velocity calculation value under the corresponding water turbidity data is calculated, and the filtration velocity calculation value is compared with the detected filtration velocity detection value.

[0016] Step 2: If the calculated filtration rate corresponding to turbidity is equal to the detected filtration rate, proceed to the analysis of the pressure filtration data; if the calculated filtration rate corresponding to turbidity is greater than the detected filtration rate, generate a second blockage judgment signal and determine whether the first blockage judgment signal was transmitted in Step 2; if the calculated filtration rate corresponding to turbidity is less than the detected filtration rate, first determine whether the first blockage judgment signal was generated in Step 2, and then determine whether the first repair judgment signal was transmitted in Step 2.

[0017] In a preferred embodiment of the present invention, the steps for analyzing the filtration efficiency data at several units are as follows:

[0018] Step 1: Several units receive the water filtration rate detection value and filtration pressure data of the filter screen inside the coal washing tank from the data acquisition unit. Then, by calculating the filtration pressure data, the calculated water filtration rate value under the corresponding filtration pressure data is calculated, and the calculated water filtration rate value is compared with the detected water filtration rate detection value.

[0019] Step 2: If the calculated filtration speed corresponding to the filtration pressure is greater than the detected filtration speed, a blockage judgment signal 3 is generated, and the system checks whether other signals are being transmitted. If the calculated filtration speed corresponding to the filtration pressure is equal to the detected filtration speed, no abnormality is detected, and no arbitrary operation is performed. If the calculated filtration speed corresponding to the filtration pressure is less than the detected filtration speed, and a repair judgment signal 2 is generated during water flow turbidity data analysis, a repair execution signal 2 is generated.

[0020] In a preferred embodiment of the present invention, the unblocking component includes a sliding rail. A positioning rail is provided inside the filter tank body at a position corresponding to the sliding rail. Sliding platforms are installed at both ends of the positioning rail at positions corresponding to the sliding rail. A first unblocking platform is slidably connected to the inner side of the positioning rail. A second unblocking platform is slidably connected to the inner side of the positioning rail corresponding to one side of the first unblocking platform. A compression frame is installed on the outer side of the lower surface of the unblocking platform via an electric push rod. A suction pipe is installed on the inner side of the lower surface of the unblocking platform via an electric push rod. A diamond-shaped cylinder is installed at the middle position of the lower surface inside the compression frame. A telescopic hose is installed at the upper end of the diamond-shaped cylinder. Limit plates are installed on the outer wall of the telescopic hose in four directions. A limit rod is installed on the lower surface of the compression frame corresponding to the position of the limit plate. A second diamond-shaped cylinder is installed on the outer side of the lower surface of the second unblocking platform via an electric push rod. A compression column is installed at the middle position of the lower surface of the second unblocking platform via an electric push rod. Sealing gaskets are installed on the lower surfaces of both the first and second diamond-shaped cylinders.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By comparing and analyzing the data of factors affecting the filtration rate when the filtration rate is abnormal through the flow water intelligent monitoring component, abnormal filtration rate caused by differences in water volume, water turbidity, and pressure can be detected in a timely manner, and countermeasures can be taken in time to reduce the adverse impact on the coal washing efficiency of the filtration pool. It can also determine whether the abnormal filtration rate is caused by filter plate blockage. If the abnormal filtration rate is caused by filter plate blockage, the flow water intelligent monitoring component can compare and analyze the blockage data, so that when several units transmit the blockage location data to the data execution unit for blockage removal, the data execution unit can push or pull the blockage from the upper or lower side of the screen plate according to the analysis results of several units, thereby reducing the adverse impact on the screen holes on the screen plate and reducing the impact on the accuracy of the coal washing operation of the screen plate.

[0023] 2. After receiving signals through the digital control unit, the positions of rhomboid cylinder one and rhomboid cylinder two are controlled, so that the blockage can be cleared by a combination of suction and pushing. When suction and pushing are used simultaneously to clear the blockage in the screen holes, the screen plate is stable under the clamping of rhomboid cylinder one and rhomboid cylinder two on the upper and lower sides, and will not deform due to large external forces. Moreover, when clearing the blockage, the cleared blockage is collected and will not cause the screen holes to become blocked again by the water flow. Attached Figure Description

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figure 1 and Figure 5 As shown, the intelligent water flow monitoring system for coal washing includes a filter tank body 1, a water flow intelligent monitoring component, a computer, and a dredging component. The filter tank body 1 has a screen plate body 2 installed on its inner side wall. The water flow intelligent monitoring component includes a data acquisition unit, a data processing unit, and a data execution unit.

[0034] The steps for analyzing the factors affecting filtration rate at several units are as follows:

[0035] Step 1: Several units receive the filtration velocity detection values, water volume data, water turbidity data, and filtration pressure data of the filter screen inside the coal washing tank from the data acquisition unit. Then, by calculating the water volume data, water turbidity data, and filtration pressure data, the filtration velocity calculation values ​​are calculated for the corresponding water volume, turbidity, and filtration pressure. The three filtration velocity calculation values ​​are then compared with the detected filtration velocity detection values.

[0036] Step 2: If the calculated filtration rate CV corresponding to the water volume is greater than the detected filtration rate LV, then the damage status of the filter tank is checked. If the filter tank is determined not to be damaged, a blockage judgment signal 1 is generated, and the process jumps to Step 3; if the filter tank is determined to be damaged, a repair execution signal 1 is generated; if the calculated filtration rate CV corresponding to the water volume is equal to the detected filtration rate LV, the process jumps to Step 3; if the calculated filtration rate CV corresponding to the water volume is less than the detected filtration rate LV, the filter plate is determined to be damaged, a repair judgment signal 1 is generated, and the process jumps to Step 3.

[0037] Step 3: Before the data acquisition unit collects water flow turbidity data, it generates a stirring execution signal through several units, so that the data acquisition unit controls the stirring rod connected to the stirring motor output to fully stir the filter tank. After stirring for a period of time, the stirring operation is stopped, and then the water flow turbidity data is collected.

[0038] If the calculated filtration rate HV corresponding to the turbidity is equal to the detected filtration rate LV, proceed to step four; if the calculated filtration rate HV corresponding to the turbidity is greater than the detected filtration rate LV, generate blockage judgment signal two, and determine whether blockage judgment signal one was transmitted in step two. If blockage judgment signal one was transmitted, the filter plate is determined to be blocked, and a clearing execution signal is generated; if no blockage judgment signal one was transmitted, proceed to step four; if the calculated filtration rate HV corresponding to the turbidity is less than the detected filtration rate LV, and blockage judgment signal one was generated in step two, the filter plate is determined to be damaged, and repair judgment signal two is generated. Determine whether repair judgment signal one was transmitted in step two. If repair judgment signal one was transmitted, repair execution signal two is generated; if no repair judgment signal one was transmitted, proceed to step four; if the calculated filtration rate HV corresponding to the turbidity is less than the detected filtration rate LV, and no blockage judgment signal one was generated in step two, proceed to step four.

[0039] Step 4: The data acquisition unit compares the filtration intensity data transmitted from the data acquisition unit. If the filtration intensity data remains unchanged, it compares the calculated filtration rate YV corresponding to the filtration intensity with the detected filtration rate LV. If the filtration intensity data changes, it generates a pressure adjustment execution signal to adjust the filtration intensity of the data acquisition unit. After stabilizing the filtration intensity, the data acquisition unit re-acquires the filtration intensity data and transmits the acquired filtration intensity data to the data acquisition unit for comparison of the calculated filtration rate YV corresponding to the filtration intensity with the detected filtration rate LV.

[0040] If the calculated filtration speed YV corresponding to the filtration pressure is greater than the detected filtration speed LV, then a blockage judgment signal three is generated. If either blockage judgment signal one is transmitted from step two or blockage judgment signal two is transmitted from step three, then a clearing execution signal is generated and transmitted to the data execution unit for corresponding operation. If the calculated filtration speed YV corresponding to the filtration pressure is equal to the detected filtration speed LV, it is judged as no abnormality, and no arbitrary operation is performed. If the calculated filtration speed YV corresponding to the filtration pressure is less than the detected filtration speed LV, and repair judgment signal two is transmitted from step three, then repair execution signal two is generated.

[0041] After receiving the unblocking execution signal, the data execution unit transmits the signal to the data acquisition unit to collect the blockage data of the filter plate, and then transmits the collected blockage data to the data acquisition unit for processing.

[0042] After receiving the repair execution signal, the data execution unit acquires the data on the location of the water filter damage and the size of the damaged holes in the water filter collected by the data acquisition unit. It then transmits the water filter damage location data to the computer, causing the computer screen to display the words "water filter damaged", the water filter damage location data, and the water filter damage hole size data. The alarm is also triggered by the alarm device to prompt the staff to carry out the repair work on the water filter.

[0043] After receiving the repair execution signal 2, the data execution unit acquires the data on the location of the filter plate damage and the size of the damaged holes in the filter plate collected by the data acquisition unit. It then transmits the data on the location of the filter plate damage and the size of the damaged holes to the computer, causing the computer screen to display the words "Filter Plate Damaged", the data on the location of the damage in the water filtration tank, and the data on the size of the damaged holes in the filter plate. The alarm is also triggered by the alarm device to prompt the staff to repair and replace the filter plate.

[0044] In the existing technology, when the filtration speed slows down during coal washing in the filter tank, affecting the efficiency of coal washing, the screen plate is often directly cleaned of blockages. However, when other factors cause the filtration speed to slow down, the staff cannot detect and eliminate the adverse factors in time. Moreover, the blockage cleaning structure can easily affect the filtration operation of the screen plate holes during operation, thus reducing the coal washing efficiency of the filter tank.

[0045] By comparing and analyzing the data of factors affecting the filtration rate when the filtration rate is abnormal through the intelligent monitoring component, abnormal filtration rates caused by differences in water volume, water turbidity, and filtration pressure can be detected in a timely manner, and countermeasures can be taken promptly to reduce the adverse impact on the coal washing efficiency of the filtration pool.

[0046] The steps for analyzing the factors affecting filtration rate at several units are as follows:

[0047] Step 1: The multi-unit receives the screen aperture data BK, blockage size data, and blockage hardness data DY from the data acquisition unit. The blockage size data includes the blockage upper screen size data DS and the blockage lower screen size data DX. The size data includes length data and width data. The multi-unit compares the screen aperture data with the blockage size data, and then compares the blockage hardness data DY.

[0048] Step 2: If the width data DS of the blockage on the sieve plate is greater than the aperture data BK, and the width data DX of the blockage on the sieve plate is less than or equal to the aperture data BK, then an upward removal signal is generated and transmitted to the data processing unit to perform the upward removal operation of the blockage.

[0049] If the width data DS of the blockage on the screen plate is greater than the aperture data BK, and the width data DX of the blockage on the screen plate below the screen plate is greater than the aperture data BK, then the length data of the regions on both the upper and lower sides of the blockage that are greater than the aperture data BK are compared. If the length data of the region on the upper side of the blockage that is greater than the aperture data BK is greater than the length data of the region on the lower side of the blockage that is greater than the aperture data BK, then an upward removal signal and an upward push signal are generated, and the execution unit determines to remove the blockage upwards. If the length data of the region on the upper side of the blockage that is greater than the aperture data BK is less than the length data of the region on the lower side of the blockage that is greater than the aperture data BK, then a downward removal signal and a downward push signal are generated, and the execution unit determines to remove the blockage downwards. The operation proceeds as follows: If the difference in length between the upper and lower sides of the blockage screen plate at position BK (where the screen plate aperture data is greater than the data) is within a set range (meaning the efficiency of removing the blockage upwards and downwards is the same), then the hardness data DY of the blockage on the upper and lower sides of the screen plate is compared. If the hardness data of the blockage on the upper side of the screen plate is greater than that on the lower side, an upward removal signal and an upward push signal are generated, and the decision unit removes the blockage upwards. If the hardness data of the blockage on the upper side of the screen plate is less than that on the lower side, a downward removal signal and a downward push signal are generated, and the decision unit removes the blockage downwards. If the difference in hardness data DY between the upper and lower sides of the blockage screen plate is within a set range, then the width and length data of blockages with the same hardness data are compared according to step one.

[0050] In the existing technology, when filter plates for coal washing become clogged, the unblocking structure is often directly operated to unblock the entire surface of the filter plate, which takes a lot of time. Moreover, using only a single unblocking method for different types of clogging can easily have an adverse effect on the screen holes on the screen plate, reducing the accuracy of the screen plate in subsequent coal washing operations.

[0051] By comparing and analyzing the blockage data through the flow monitoring component, when several units transmit the blockage location data to the data execution unit for blockage removal, the data execution unit can push or pull the blockage from the top or bottom of the screen plate according to the analysis results of the several units. This reduces the adverse effects on the screen holes on the screen plate during the removal operation and reduces the impact on the accuracy of the coal washing operation of the screen plate.

[0052] Example 2:

[0053] Please see Figure 2-4As shown, the unblocking component includes a sliding rail 3. A positioning slide rail is provided inside the filter tank body 1 at a position corresponding to the sliding rail 3. Sliding platforms 4 are installed at both ends of the positioning slide rail at positions corresponding to the sliding rail 3. The sliding platforms 4 at both ends of the positioning slide rail move on the sliding rail 3 via an adjusting push rod. One end of the adjusting push rod is installed on the sliding platform 4, and the other end is installed on the inner wall of the filter tank body 1. An unblocking platform 5 is slidably connected to the inner side of the positioning slide rail. A second slidable cleaning platform 6 is connected to one side of platform 5. Platforms 5 and 6 slide on positioning rails via adjusting push rods. The other end of the adjusting push rod connected to platform 5 is connected to the inner wall of the positioning rail, and the other end of the adjusting push rod connected to platform 6 is also connected to the inner wall of the positioning rail. Collection chambers are connected to the upper ends of both platforms 5 and 6. Switch valves are installed at the connection points between the collection chambers and platforms 5 and 6. The outer wall of the collection chamber... The dredging platform 5 has several drainage holes. A compression frame 52 is installed on the outer side of the lower surface of the dredging platform 5 via an electric push rod 1. A suction pipe 51 is installed on the inner side of the lower surface of the dredging platform 5 via an electric push rod 2. A rhomboid cylinder 55 is installed at the middle position of the lower inner surface of the compression frame 52. A telescopic hose 56 is installed at the upper end of the rhomboid cylinder 55. Limit plates 53 are installed on the four sides of the outer wall of the telescopic hose 56. A limit rod 54 is installed on the lower inner surface of the compression frame 52 corresponding to the position of the limit plate 53. A rhomboid cylinder 62 is installed on the outer side of the lower surface of the dredging platform 6 via an electric push rod 3. A compression column 61 is installed at the middle position of the lower surface of the dredging platform 6 via an electric push rod 4. Waterproof sleeves are provided on the outer sides of the electric push rods and adjusting push rods. Sealing gaskets 7 are installed on the lower surfaces of both the rhomboid cylinder 55 and the rhomboid cylinder 62. The size of the rhomboid cylinder 55 and the rhomboid cylinder 62 is larger than the size of the filter holes on the filter plate body 2.

[0054] When the digital execution unit receives signals from multiple units to clear blockages in the screen plate body 2, it selects a clearing method based on the location of the screen holes to be cleared and the clearing signal indicating the blockage. If the digital execution unit only receives an upward or downward removal signal, it moves the positioning slide rails on both sides of the screen plate under the action of the adjusting push rod one. Simultaneously, the position of the clearing platform 5 is moved under the action of the adjusting push rod two. After the clearing platform 5 reaches the designated position, the electric push rod one, under the control of the digital execution unit, extends to the sealing gasket 7 at the lower end of the rhomboid cylinder 55, pressing tightly against the screen plate body 2 and creating a sealed space between the telescopic hose 56 and the blocked screen hole. When the electric push rod two moves the suction pipe 51 upward, the telescopic hose 56 is stretched under the restriction of the limiting rod 54, compressing the sealed space formed by the telescopic hose 56 and the blocked screen hole. The pressure difference between the inside and outside of the screen causes the blockage to separate from the screen holes and move into the suction pipe 51 under the action of inertia. When the electric push rod 2 retracts, the corresponding valve opens and closes after the retraction operation is completed, so that the blockage is collected into the upper collection chamber. Then the squeezing frame 52 is reset. If the digital control unit only receives an upward or downward push signal, the positioning slide rail moves under the action of the adjusting push rod 1, and the unblocking platform 6 moves under the action of the adjusting push rod 2. Under the control of the digital control unit, the electric push rod 3 extends to the sealing gasket 7 at the lower end of the rhomboid cylinder 62 and presses against the screen plate body 2. Then the electric push rod 4 extends to push the squeezing column 61 to move and push the blockage blocking the screen holes. If a take-out signal and a push signal are generated at the same time, the unblocking platform 5 and the unblocking platform 6 move synchronously to the designated position to process the blockage.

[0055] In use, this invention first compares and analyzes the data of factors affecting the filtration speed when the filtration speed is abnormal through the intelligent monitoring component. This allows abnormal filtration speed caused by differences in water volume, water turbidity, and pressure in the filtration tank to be detected in a timely manner, and countermeasures to be taken promptly to reduce the adverse impact on the coal washing efficiency of the filtration tank. It also determines whether the abnormal filtration speed is caused by filter plate blockage. If the abnormal filtration speed is caused by filter plate blockage, the intelligent monitoring component compares and analyzes the blockage data. When several units transmit the blockage location data to the data execution unit for blockage removal, the data execution unit can push or pull the blockage from the upper or lower side of the screen plate according to the analysis results of the several units. This reduces the adverse impact on the screen holes on the screen plate during the removal operation and reduces the impact on the accuracy of the coal washing operation of the screen plate.

[0056] When the digital execution unit receives signals from multiple units to clear blockages in the screen plate body 2, it selects a clearing method based on the location of the screen holes to be cleared and the clearing signal indicating the blockage. If the digital execution unit only receives an upward or downward removal signal, it moves the positioning slide rails on both sides of the screen plate under the action of the adjusting push rod one. Simultaneously, the position of the clearing platform 5 is moved under the action of the adjusting push rod two. After the clearing platform 5 reaches the designated position, the electric push rod one, under the control of the digital execution unit, extends to the sealing gasket 7 at the lower end of the rhomboid cylinder 55, pressing tightly against the screen plate body 2 and creating a sealed space between the telescopic hose 56 and the blocked screen hole. When the electric push rod two moves the suction pipe 51 upward, the telescopic hose 56 is stretched under the restriction of the limiting rod 54, compressing the sealed space formed by the telescopic hose 56 and the blocked screen hole. The pressure difference between the inside and outside of the screen causes the blockage to separate from the screen holes and move into the suction pipe 51 under the action of inertia. When the electric push rod 2 retracts, the corresponding valve opens and closes after the retraction operation is completed, so that the blockage is collected into the upper collection chamber. Then the squeezing frame 52 is reset. If the digital control unit only receives an upward or downward push signal, the positioning slide rail moves under the action of the adjusting push rod 1, and the unblocking platform 6 moves under the action of the adjusting push rod 2. Under the control of the digital control unit, the electric push rod 3 extends to the sealing gasket 7 at the lower end of the rhomboid cylinder 62 and presses against the screen plate body 2. Then the electric push rod 4 extends to push the squeezing column 61 to move and push the blockage blocking the screen holes. If a take-out signal and a push signal are generated at the same time, the unblocking platform 5 and the unblocking platform 6 move synchronously to the designated position to process the blockage.

Then, by calculating the pressure data, the calculated value of water filtration speed under the corresponding pressure data is calculated, and the calculated value of water filtration speed is compared with the detected value of water filtration speed. Y2: If the calculated filtration speed corresponding to the filtration pressure is greater than the detected filtration speed, a blockage judgment signal three is generated. If either blockage judgment signal one is transmitted from step two or blockage judgment signal two is transmitted from step S2, a clearing execution signal is generated and transmitted to the data execution unit for corresponding operation. If the calculated filtration speed corresponding to the filtration pressure is equal to the detected filtration speed, it is judged as no abnormality, and no arbitrary operation is performed. If the calculated filtration speed corresponding to the filtration pressure is less than the detected filtration speed, and repair judgment signal two is transmitted from step S2, a repair execution signal is generated.
