[0002] A high-pressure automatic backwash filter station is a device that can operate under high pressure, filter fluids, and automatically backwash to clean the filter medium. It is generally used in industrial, municipal, and agricultural fields.

When the filter station is backwashed, part of the fluid will be discharged from the filter station along with the impurities. At this time, the filter station without the fluid recovery function cannot recycle the discharged fluid for reuse, which leads to a waste of fluid resources, which not only reduces the use effect of the high-pressure automatic backwashing filter station, but also reduces the use efficiency of the high-pressure automatic backwashing filter station.

[0032] The effect achieved by the entire mechanism is: when it is necessary to filter the fluid, first connect the input end of one of the third electric valves 119 (close to the one-way valve 118) on the ultra-large flow and high pressure automatic backwashing filter station to the output end of the pipeline for conveying the fluid (the fluid to be filtered), then connect the other third electric valve 119 on the ultra-large flow and high pressure automatic backwashing filter station to the input end of the pipeline for conveying the fluid (the fluid obtained after filtration), then connect the controller 120 to the external power supply through the prepared power cord, then turn on the controller 120, set the pressure difference threshold, the output end rotation angle of the motor body 208 and the basic usage procedure, and when everything is ready, use the controller 120 to open the two There are three third electric valves 119 and four first electric valves 111. At this time, the output end of the pipeline conveying the fluid will directly convey the fluid to the inside of the three-way pipe 117 through the cooperation of one of the opened third electric valves 119, and then convey it to the inside of the second multi-way pipe 116. Then, through the cooperation of two of the opened first electric valves 111, it is diverted and conveyed to the inside of the two concave blocks 103, and then through the cooperation of the corresponding two groups of arc holes 107, it is conveyed to the inside of the corresponding cylinder 104, and then enters the inside of the corresponding filter element 125. When the fluid passes through the two filter elements 125 and enters the inside, under the action of the two filter elements 125, the impurities mixed in the fluid entering the corresponding filter element 125 can be filtered out, and then enter The fluid entering the corresponding filter element 125 will be transported to the corresponding shunt pipe 123, then transported to the corresponding water outlet 109, and then transported to the corresponding, opened first electric valve 111, and then collected to the first multi-way pipe 112, and then transported to the inside of another third electric valve 119 through the cooperation of the first connecting pipe 113, and finally input from the input end of the pipeline for transporting the fluid, that is, the filtered fluid is transported away. At the same time, the controller 120 is used to start the first sensor 114 (pressure difference sensor) and the second sensor 124 (pressure difference sensor). At this time, the started second sensor 124 will detect the fluid pressure at the inlet of the filter station (i.e., the position of the three-way pipe 117), and start The first sensor 114 will detect the fluid pressure at the outlet of the filter station (i.e., the position of the first connecting pipe 113), and then the first sensor 114 and the second sensor 124 will transmit the detected pressure data to the controller 120. Then the controller 120 will use the pressure data at the inlet of the filter station to subtract the pressure data at the outlet of the filter station to obtain the pressure difference, and then compare the calculated pressure difference data with the pressure difference threshold value set in advance by the controller 120. When the pressure difference data calculated by the controller 120 is lower than the pressure difference threshold value set in advance by the controller 120, it means that the filter station can continue to filter the fluid. When the pressure data calculated by the controller 120 reaches the pressure difference threshold value set in advance by the controller 120,This indicates that the filter station needs to perform a backwashing operation. At this time, the controller 120 will directly close a first electric valve 111 (the other two first electric valves 111 are normally open, and one of the two first electric valves 111 is open) and another third electric valve 119, and at the same time open the corresponding second electric valve 115 and the water pump 204 on the concave block 103 that does not use the filter element 125. Then, the filter element 125 on one of the concave blocks 103 will continue to filter the fluid, and the filter element 125 on the other concave block 103 will stop filtering the fluid. Then, the fluid that reaches the inside of the first multi-way tube 112 (the clean fluid obtained after filtration) will pass through the corresponding opened first electric valve 111 on the concave block 103 that does not use the filter element 125, and then according to The fluid passes through the corresponding water outlet hole 109 and the corresponding shunt pipe 123 to reach the inside of the filter element 125 that has not been filtered, that is, the filtered fluid is used to backwash the filter element 125 that has not been filtered. When the filter element 125 is backwashed by the fluid, the impurities on the surface of the filter element 125 will be washed off, and then pass through the corresponding two groups of arc holes 107 to be guided to the space composed of the concave block 103 and the bottom plate 102, and then through the corresponding sewage hole 108, it is guided to the inside of the opened second electric valve 115, and then it is transported to the inside of the arc pipe 218, and then it is transported to the inside of the box 201. When the fluid with impurities reaches the inside of the box 201 and contacts the surface of the semicircular filter plate 211, At this time, under the action of the semicircular filter plate 211, impurities mixed in the fluid can be filtered out, allowing the fluid to pass through and flow to the bottom of the inner wall of the box body 201. At this time, the started water pump 204 will directly extract the fluid flowing to the bottom of the inner wall of the box body 201 under the cooperation of the second connecting pipe 205 and the first connecting pipe 203, and transport it to the inside of the one-way valve 118, and then transport it back to the inside of the three-way pipe 117 for recycling and reuse. When the filter element 125 that has not filtered the fluid has undergone a period of backwashing operation, the controller 120 will close the previous first electric valve 111 and open another first electric valve 111 (the other two first electric valves 111 are normally open, and one of the two first electric valves 111 that was previously opened is closed, and the other one that was previously closed is closed). The first and second electric valves 115 are opened, and the second electric valve 115 that was previously opened is closed, and the second electric valve 115 that was previously closed is opened. Then, the above operation steps are repeated to perform backwashing operation on the filter element 125 that has not been backwashed before, until the filter element 125 is also backwashed for the same period of time. When the two filter elements 125 have completed the backwashing operation, and the pressure difference data calculated by the controller 120 is lower than the pressure difference threshold value set by the controller 120 in advance, the controller 120 will turn off the water pump 204 and the two second electric valves 115, and open the closed first electric valve 111 and the other third electric valve 119 at the same time to continue the fluid filtering operation. When it is necessary to clean the impurities on the semicircular filter plate 211, the two sets of electric push rods 214 are started first.At this time, each set of electric push rods 214 activated will drive the block 213 connected thereto to move out from the inside of the corresponding discharge hole 212, and then the controller 120 will be used to activate the motor body 208. At this time, the activated motor body 208 will drive the paddle plate 207 to swing left and right under the cooperation of the perforated box plate 202, the rotating rod 206 and the box body 201. At this time, the paddle plate 207 swinging left and right can paddle the impurities left on the surface of the semicircular filter plate 211 to the inside of the two discharge holes 212, and then be diverted away through the cooperation of the two guide shells 215 and the two auxiliary holes 216. When the impurities on the surface of the semicircular filter plate 211 are cleaned, the controller 120 will use the cooperation of the two sets of electric push rods 214 to reset the two blocks 213 to the inside of the discharge hole 212 respectively. When the two blocks 213 complete the reset operation, the controller 120 will simultaneously close the two sets of electric push rods 214.
