How to operate the snail sludge dewatering machine for the first time?


The application of stacking screw dehydrator in ceramic processing wastewater. The dehydrated mud cake is discharged from the mud cake outlet and sent to the mud truck directly or through a shaftless screw conveyor for reuse. The sludge tank should be equipped with a stirring device, and the dewatering machine should continue to stir the sludge before and during the operation to ensure the relative stability of the sludge concentration. The technicians should confirm the installation position of the machine and the switch when performing (the previous time) formal operation.


1. Check before turning on the snail sludge dewatering machine


Whether there is debris in the mixing tank, whether the filter body empties the sludge, and whether there is a sludge at the head of the screw shaft.


2. Start-up steps of snail sludge dewatering machine


(1) Add flocculant powder to the PAM preparation system and turn on the stirring device;


(2) Manually spray the fixed disc on the filter body for 2 minutes;


(3) Turn on the main body drive motor and check whether the rotation direction of the main body drive motor is correct, while continuing to spray for 2 minutes;


(4) Start the flocculant supply pump, mud pump and flocculation stirring motor in sequence;


(5) Adjust the mud feed volume and the speed of the screw shaft, and adjust the spacing of the back pressure plate to reduce the processing capacity and moisture content.


3. Check after turning on the snail sludge dewatering machine


Whether the screw shaft rotates normally, whether the mud level of the mixing tank is stable, whether the rotating parts are operating normally, and whether there is abnormal noise.


4. Shutdown steps of snail sludge dewatering machine


(1) Turn off the sludge feeding pump and stop feeding the sludge;


(2) Close the dosing pump and dosing system, and stop dosing;


(3) Empty the flocculation mixing tank and stop the flocculation stirring motor;


(4) After all the sludge is drained (not less than 30 minutes), manually spray the filter body for 5 minutes to rinse the equipment;


(5) Turn off the power.
