The first reason for the belt filter to stop working should be that the water channel in the equipment is blocked. When some of the water channels in the equipment are blocked, the filtrate cannot enter the equipment or cannot be excluded from the equipment, so that the belt filter equipment will suddenly stop running. Because in this kind of clogging, even if the filtrate is in contact with the filter cloth, since there is no pressure difference, the filtering and separation effect cannot occur, so at this time, the belt filter will naturally stop working. The control system of the belt filter equipment directly affects the filtration of the filtrate. When the control system has an error, the belt filter will naturally not work normally. At this time, it is very dangerous to run the belt filter reluctantly. Therefore, in such a situation, Shanghai Qili experts advise users not to forcibly turn on the belt filter, and stop the equipment in time and seek professional maintenance. Personnel to perform repairs.

Introduction to the correct operation method of belt filter

First, adjust the constant pressure valve pressure index, generally adjusted to 0.05-0.10MPA, to maintain the stability of the filtration pressure. Then open valves 11 and 15.

Second: Open valves 1, 2, and 6, the filter slurry is pressed into the belt filter by compressed air, open valve 3 or 4, and the filtrate enters the metering tank.

Third: Observe the filtrate. If the filtrate is clear, the surface filtration is normal. It is found that the filtrate is turbid or with filter residue, indicating that there is a problem in the filtration process, the filtration should be stopped, and the filter cloth and installation should be checked, whether the filter plate and filter frame are deformed, whether there are cracks, whether there is any leakage in the pipeline, etc.

Fourth: Record the amount of filtrate and the corresponding time. When the reading of the pressure gauge at the inlet of the belt filter increases to close to the pressure on the constant pressure tank, the measurement is ended, and the filtrate can be discharged by opening valve 9 or 10.

Fifth: Close valve 6, open valve 7, wash the filter residue with clean water, and measure the amount of filtrate and the corresponding time at the same time to get the filtration speed.

Sixth: Close valve 3 and valve 7, open valve 8, blow the filter residue with compressed air, which is conducive to the fall of the filter residue, then close valves 5 and 8, unload the filter residue and wash the filter cloth, such as in the constant pressure tank If there is excess material, you can open valve 26 or valve 19, use air to press the excess material into the batching tank or discharge it, and finally close valves 11 and 15, and turn off the air compressor.

Belt filter manufacturers understand that in the face of the hot summer, high temperature weather will make the working environment of the belt filter worse, which will cause the belt filter to encounter some failures in the work. Today, the belt filter manufacturer is Everyone introduces in detail how to use the belt filter normally in summer.

The first item: We must always pay attention to the oil temperature of the hydraulic oil.

The second item: we need to check the wiring of the belt filter at intervals. Because the temperature in summer is very high, natural moisture evaporates quickly, so the air contains more water molecules, coupled with the harsher working environment of the belt filter, basically there is water around the belt filter. Therefore, the more moisture in the working environment of the belt filter and the humid working environment can easily cause the circuit of the belt filter circuit, which may cause damage to the belt filter.
