Why the sludge dewatering filter press is kept clean and tidy


With the deepening of understanding of environmental pollution control, sewage treatment plants have been built and put into operation in major cities. The invention effectively solves the problem of sludge treatment and disposal. There is no time to delay. Various environmental protection policies have also put forward more and more clear regulations on sludge treatment. For example, the water content of the sludge landfill is less than 50; the organic matter content is less than 30%. At the same time, considering that sludge is a resource, we began to limit the direct landfill of sludge, the increase in landfill costs, and the market's demand for reduction and resource utilization.


Why the sludge dewatering filter press is kept clean and tidy


Place the filter plate in the specified amount, and prohibit starting operation with a filter plate less than or greater than the specified number. Rinse the filter cloth frequently and check the filter carefully. When starting to clean the filter, slowly open the feed valve. First, the filtrate is cloudy and slowly shuts down, which is normal. After closing the filtrate, the feed valve is fully opened. Use HM46 or HM48 as hydraulic oil and keep it clean.


When the new machine runs for a week, the hydraulic oil should be replaced once. When changing the oil, drain the hydraulic oil used in the oil tank and cylinder, and clean the oil tank. After one month, it should be replaced once, and then every six months. The filter press ensures the normal use of the filter press.


Record the operation, the filter press records the operating status of the equipment and the problems that have occurred. If there is a fault, it should be repaired in time, and fault operation is strictly prohibited. When the filter plate moves on the main beam, the forces should be balanced, and the removed filter plate should be flattened to prevent bending and deformation, and the sealing surface of the sealing plate between the filter plates should be checked frequently.


When the treated sludge is landfilled in the sludge treatment process, the sludge processed by the automatic high-pressure sludge dewatering filter press can greatly reduce the sludge accumulation site and reduce the cost during transportation.
