Order of mechanical operation of the entire device:

1. Car wash wastewater is introduced into the filtration chamber 37 through the input pipe 35, and the wastewater raises the rear floating plate 61, which loosens the rear rope 48, whereby the extrusion block 44 acts as an extrusion spring 42. The rear rack plate 27 moves forward, which causes the rack block 64 to move forward, whereby the rear rack plate 27 meshes with the rotary gear 45, and the rack block 64 Engages with the stirring gear 24.

2. The motor 28 operates to rotate the stirring shaft 24 in an interlocking manner, whereby the stirring gear 25 and the stirring blade 23 are interlocked to rotate, and the stirring gear 25 interlocks the rack block 64 to move to the left. As a result, the rack plate 27 is interlocked and moved to the left, whereby the rotary gear 45 is rotated and the connecting spring 62 is compressed, and the rotation of the rotary gear 45 is interlocked with the rotary shaft 32 to rotate the rotary gear 45. The pressure plate 5 is raised, thereby raising the friction rod 57, whereby the two flow holes 6 are communicated with the filtration pipe 11, and as the pressure plate 5 is raised, waste water is pushed into the filtration pipe 11 and the filter is pushed. The water is filtered under the action of the screen 17, and the filtered water flows into the stirring chamber 22 to put a flocculant into the stirring chamber 22, which reacts under the action of the stirring blade 23. Causes precipitation.

3. 3. When the pressure plate 5 rises to the uppermost position, the pressure plate 5 controls the two electromagnetic plates 27 to stop repulsion, whereby the two electromagnetic plates 27 act under the action of the compression spring 49. As they approach each other, the rotary rod 46 rotates to push the rack plate 27, which separates the rack plate 27 from the rotary gear 45, separates the rack block 64 from the stirring gear 24, and connects the rack plate 27 and the connecting plate 52.

Is closed, and the through hole 34 communicates with the input pipe 35 and the communication pipe 10, whereby the wastewater entering from the input pipe 35 enters the lower side of the pressure plate 5 through the communication pipe 10.

4. When the pressure plate 5 rises, the pressure plate 5 interlocks the friction rod 57 to move upward, thereby interlocking the telescopic block 9 and moving it upward, and interlocking the cutting block 16 by the transmission of the thin string 12. When the cutting block 16 cuts the filter cake removing pipe 15 and the pressure plate 5 stops ascending, the electromagnetic block 66 operates to return the friction rod 57, whereby the expansion / contraction block 9 is restored, whereby the cutting block 16 is restored, whereby the filter cake removing hole 55 communicates with the filter cake removing pipe 15, thereby discharging the filter cake generated by filtration, and the friction rod 57 discharges the filtering pipe 11. And the filtration chamber 37 are closed.

5. When the lower side of the pressure plate 5 is filled with water again to raise the front floating plate 48, the front extruded block 44 is pushed out, whereby the front rack plate 27 moves rearward and meshes with the rotary gear 45. When the rack plate 27 on the side moves backward, at this time, the electromagnet 65 operates and repels the rack block 64, whereby the rack block 64 meshes with the stirring gear 24, whereby the stirring gear 24 rotates normally. , The rotary gear 45 rotates in the opposite direction, whereby the rotating shaft 32 rotates in the opposite direction, thereby lowering the pressurizing plate 5, thereby operating the filter cake removing mechanism 67 again, filtering, and the pressurizing plate. When 5 moves to the bottom, the electromagnet 65 operates to attract the rack block 64 and stop the electromagnetic plate 52 from repelling each other under the control of the pressure plate 5, thereby stopping the rack plate 27. Is restored again, and at this time, the electromagnetic block 66 is activated to restore the filter cake removing mechanism 67, and the apparatus completes the restoration.

6. After the precipitation occurs due to aggregation, the first electromagnetic switch 19 and the second electromagnetic switch 51 are turned on, whereby the precipitation and water are discharged.
