In the wall, after the operator adds alum, the stirring motor starts to work at this time, and then the moving stirring motor drives the transmission belt to work, and then the moving transmission belt drives the rotating part to work, and then the moving rotating part drives the stirring fan to start Rotate, and then the stirring fan blade completes the stirring work of the waste water.
The waste water recovery device used for cleaning the filter press according to claim 7, characterized in that: the filter assembly further comprises a cylinder wall arranged on the connecting piece, and a cylinder wall arranged around the cylinder wall Three brackets, a water inlet pipe and a water outlet pipe arranged on the cylinder wall, and a sludge discharge pipe arranged at the bottom end of the cylinder wall, the water inlet pipe is connected with the conveying pipe, and the water outlet pipe is connected with the cleaning part.
A working method for a waste water recovery device after cleaning a filter press, which is characterized in that it includes:

S1: When the filter press plate is required to start to filter the sewage containing more sludge, the squeezing device starts to work at this time, and then the moving squeezing device drives the pressure plate to start working, and then the pressure between the plates When the pressing force reaches the expected value, the squeezing device stops working. At this time, sewage flows in from the water inlet device of the filter press, and then the sewage enters the filter plate, and then starts the filter press work. At this time, the clean water at the press filter enters In the water outlet device, the clean water that flows out is transported to the designated location, and then the handling trolley starts to work, and then the moving handling trolley drives the filter plate to start moving, which will cause the filter plate on the filter plate to fall into the funnel, and then the The filter cake is transported to the designated location to complete the filter press work of the filter press;

S2: When the filter press works for a long time, more water-insoluble stains will adhere to the filter plate, and then the drive motor starts to work at this time, and then the moving drive motor drives the drive screw to work, and then the transmission of the movement The screw drives the connecting part to start moving on the drive screw, and then the moving connecting part drives the transmission plate to start moving, thereby completing the driving work of the device;

S3: When the drive plate starts to move, the moving drive plate drives the drive slide to start moving on the drive slide and the guide tube, and the moving drive plate can adjust its position on the walking slide, so that the drive plate can Located at the designated position, the position of the cleaning part on the transmission plate can be adjusted, and the cleaning of the filter plate can be completed, thereby completing the cleaning of the filter plate;

S4: When the cleaning department is preparing to clean the filter plate, the transmission motor starts to work at this time, and the moving transmission motor drives the coupling to work, and then the moving coupling drives the screw to work, and then the rotating wire The rod drives the recovery slide to work, and the moving recovery slide starts to move on the recovery slide, and the position of the recovery slide on the recovery slide can be adjusted, so that the receiving part can be located at the exit of the funnel, and the The waste water from cleaning the filter plate is collected in the receiving part;

S5: After the waste water is located in the receiving part, the waste water flows out of the conveying pipe, and then the waste water flows into the cylinder wall. At this time, after the operator adds alum, the stirring motor starts to work, and the moving stirring motor drives the transmission belt Start to work, and then the moving transmission belt drives the rotating part to work, and then the moving rotating part drives the stirring fan to start to rotate, and then the stirring fan completes the stirring of the wastewater until the set time is reached, and the stirring motor stops at this time Work, and then the stirring fan stops rotating;

S6: When the stirring fan stops rotating and stands for a period of time, the impurities in the water will sink to the bottom of the cylinder wall, and then the clear water will flow in from the outlet pipe, and the clear water will be transported to the cleaning part, and the sludge will be removed from the sewage. The mud is discharged from the discharge pipe to complete the filtering work;

S7: When the cleaning work is over, the drive motor works in the reverse direction, so that the receiving part is in the initial position. At this time, the driving part starts to work, and then drives the driving slider to move on the lifting slide rail, and then adjusts the position of the receiving part, so that The receiving part is located at a safe height.
