Analysis of common troubleshooting methods for closed plate filters

2021-05-08

The closed plate filter is an energy-saving, airtight operation precision clarification and filtration equipment, which is suitable for salad oil, gross oil, petroleum, resin, food, pharmaceutical, polyether, environmental protection water treatment and other industries. The closed plate filter has small volume, high filtration efficiency, good transparency and fineness of filtrate, no material consumption, no consumption of filter paper, filter cloth or paper core, but only a small amount of filtering aid, so the filtration cost is very low, and the equipment is easy to operate, maintain and clean. The following is a detailed explanation of the common troubleshooting methods of the closed plate filter.

1. Leakage of oil in closed plate filter: The hydraulic system of closed plate filter mainly provides pressure, when the oil cavity A is filled with more oil, the piston moves to the left and presses the filter plate to close it. When oil chamber B is filled with more oil, the piston moves to the right and the filter plate of the closed plate filter is loosened. Due to the precise manufacturing, the hydraulic system of closed plate filter has less failure, so it is possible to pay attention to the daily maintenance.

Solution: Remove and inspect the valve, replace the O-ring, clean and inspect the solenoid valve or replace the solenoid valve.

2. closed plate filter walking sluggish to: sometimes due to the guide rod on the oil, too much stain will also lead to plate and frame filter filter plate walking sluggish, and even will go off and fall down.

Solution: The closed plate filter cleans the guide rod and greases it in time to ensure its lubricity.

3. Gouge marks on the filter plate of the closed plate filter: The filter plate of the closed plate filter washes out some gouge marks at the corners after several years of use for some reasons. Once the groove marks appear, the closed plate filter will expand rapidly until it affects the formation of filter cake.

Solution: clean up the closed plate filter groove, leaking fresh surface to, available small saw blade, etc. clean up; black and white two patching agent at a ratio of 1:1 deployment, the deployment of patching agent coated in the groove, coated full slightly higher; quickly set the filter filter cloth, the filter filter plate squeezed together, so that the patching agent and the filter cloth stick together, while squeezing the groove, squeeze a period of time, the adhesive natural molding, no

4. Uneven formation of filter cake of closed plate filter: Insufficient or too thin material supply, in addition to blockage can cause this phenomenon.

Solution: Increase the feeding adjustment process of the closed plate filter to improve the feeding, clean the filter cloth or replace the filter cloth to clear the blockage, feeding hole, drainage hole and other methods.
