When the switching power supply of the sludge filter press is cut off, the actual operating staff shall first carry out patrol inspection on a production line, and then check the causes of the problems one by one. If there are multiple power cuts, it is necessary to identify whether the motor trips or the power cuts caused by other factors

The primary factor for the motor tripping is that it is immediately related to the motor itself and the spread of sludge on the filter screen. Then, two 1.5KW bevel gears and gear racks are selected as the speed reduction motor to drive. Under normal circumstances, the two motors can meet the needs of machine and equipment operation. However, when the external conditions change, the bearing force of the squeezing roll will be uneven, and the current of the motor will rise, In case of power failure of the frequency conversion protection equipment of the motor, the server motor will terminate its operation. The uneven bearing capacity of the extraction roller is related to the sludge distribution. For this situation, the division of the regulated sludge is the first step. In the case of sludge load operation, the staff need to negotiate the perspective of the leveling gate valves on both sides of the extraction and filter press, And then change the thickness of the sludge to restore its uniform distribution.

The second is to ensure that the sludge does not overflow from the side according to the adjustment support force. The method is to adjust according to the screw of the air compression extruder of the left and right filter belts, and make the mud scraper lift the filter cake. After the power of the driving motor of the sludge filter press is changed from 143kw to plate chain during operation, the output power of the rotating shaft can reach 83kw without reducing the transportation capacity. If the output power of the transmission system of the rotating shaft declines, the original driving motor can be replaced with a small output power point, and the driving system software is changed to a reducer to make it operate normally, At this time, both the optical fiber coupler and the transmission device can operate normally. Because the output power is reduced, the motor needs to be replaced. The feeding method is scraping type. The bottom end is filled with raw materials. The raw materials are picked up by the silo through the bottom end, which belongs to passive feeding. The feeding port and the feeding port are on the same side, and the rotation direction is the opposite direction.
