[0041] Working principle;

[0042] Firstly, the driving motor 301 is started by the DSP controller 304, the driving motor 301 drives the lead screw 303 to rotate, so that the connecting plate 400 moves under the driving of the nut seat 302, at the same time, when the proximity sensor 408 inserted at the top of one side of the connecting plate 400 detects that the connecting plate 400 moves above one group of filter plates, the proximity sensor 408 will detect the distance change and generate a corresponding signal, then the signal is sent to the DSP controller 304 through the wire, and the DSP controller 304 accurately controls the driving motor 301 to stop rotating according to the received signal, and at the same time starts the delivery pump 205;

[0043] The pumping assembly located at the top of one side of the bottom plate 100 works, the delivery pump 205 at one side of the bottom plate 100 is started under the control of the DSP controller 304 to draw water from the water tank 204, the water flows along the delivery pipe 203, part of the delivery pipe 203 is located in the inner cavity of the drag chain 201, the drag chain 201 fixes the delivery pipe 203 through the fixing clamps 206 arranged on the top of one end of the fixed strip 202, the topmost fixing clamp 206 is connected with the connecting plate 400 through the connecting strip 207, so as to ensure that the delivery pipe 203 can also be stably connected when the cleaning assembly moves;

[0044] After the water flows through the delivery pipe 203, it extends upward above the connecting plate 400, then winds downward through the connecting plate 400 into the input end of the one-to-two pipe 403, the one-to-two pipe 403 delivers the received water to the housings 404 on the left and right sides of the mounting plate 407 respectively, and the housings 404 on the left and right sides of the mounting plate 407 are connected through a plurality of fixed rods 406, one end of the fixed rod 406 winds downward so that the housing 404 can better close to the filter plate, the water in the housing 404 is sprayed out through a plurality of downward inclined spray pipes 405, and the filter plate is washed, at the same time, the telescopic end of the electric push rod 401 extends downward, so as to drive the spray pipe 405 to move downward along the filter plate, and wash the lower part of the filter plate;

[0045] During the rinsing process, the dropped residues can slide through the guide grooves 105 between the support frames 101, and drop into the containing boxes 103 in the collecting box 102 due to the alignment of the lower opening of the guide grooves 105 with the inner cavity of the containing boxes 103, and when the containing boxes 103 are filled, the containing boxes 103 can be slid out from one side of the collecting box 102, facilitating the cleaning of the residues;

[0046] Meanwhile, when the proximity sensor 408 detects that the distance is less than a certain degree and generates a corresponding signal, the signal is sent to the DSP controller 304 through the wire, and the DSP controller 304 controls the retracting end of the electric push rod 401 to retract accurately according to the received signal, and controls the driving motor 301 to move the cleaning assembly to the next filter plate position or return to the initial position, etc.
