Vacuum belt filter has high filtration efficiency

Vacuum belt filter has high filtration efficiency

The reason why the vacuum belt filter has high filtration efficiency is mainly reflected in the following points:

1. The vacuum belt filter adopts air cushion type support and water film support. The sludge dewatering equipment tape floats on the air cushion or liquid film, which can effectively reduce the friction resistance of the belt running and improve work efficiency;

2. In terms of the overall structure, the vacuum belt filter press adopts a detachable frame structure, and such a structural device can facilitate the maintenance of the equipment and the convenience of installation;

3. This machine adopts closed vacuum management to form a very effective vacuum sealing body. Unlike diaphragm filter presses, there is an essential difference between the two.

The filter cloth from which the filter cake is removed is regenerated after being washed, and after passing through a set of backup rolls and correcting devices, it re-enters the filter zone and begins to enter a new filtration cycle. The liquid entering the vacuum chamber is then discharged outside the machine through the gas-water separator. As the rubber belt moves, the formed filter cake will enter the filter cake washing zone and the suction drying zone in turn, and finally the filter cloth is separated from the tape, and the filter is unloaded. The filter cake is discharged from the cake roll.

The rubber vacuum belt filter uses a filter cloth as a filter medium, and a ring rubber belt is used as a vacuum chamber as a whole. The endless tape is continuously driven by the motor. The filter cloth is laid on the tape and runs synchronously with it, so that the tape is in sliding contact with the vacuum, and the slurry is evenly distributed on the filter cloth by the distributor. After the vacuum chamber is connected to the vacuum system, a vacuum suction zone is formed on the tape, and the sewage treatment equipment is integrated, and the filtrate is passed through the filter cloth through the transverse grooves on the tape, and enters the vacuum chamber through the small holes, and the solid particles Then it is trapped on the filter cloth to form a filter cake.

Have you ever encountered a diaphragm filter press ? In daily operation, we often find that after the diaphragm filter press has been running for a long time, it will overheat. In order to avoid this overheating, what measures can be taken to solve it? Today, the filter equipment is for everyone. Explain in detail.

There are two reasons for the overheating of the diaphragm press: one is the hydraulic system and the other is the filter press.

The hydraulic system of the filter press is closely related to the temperature. The temperature can be controlled by installing a heat release device, so that the filter press can operate normally, and the special attention should be paid to the temperature of the hydraulic station. This will affect the hydraulic system and cause the system to malfunction.

The filter press filter plate is made of polypropylene material, which can effectively prevent overheat treatment, slow down the temperature increase, reduce the decomposition and oxidation deterioration of the filter press filter plate, and use the filter plate of Yancheng. cycle. Reduce the damage of the filter plate, increase the production rate, and seek greater profits.

The operator has a certain understanding of the diaphragm filter press, knowing which parts need to be prevented, but also need to know to change any defense?

Diaphragm filter press installation is generally in a cool and ventilated way, to avoid direct sunlight, in addition to the temperature changes, take various measures to prevent mechanical overheating, the temperature of the machine can be watered by the method. It can also be stopped, and after the mechanical heat is dissipated, the operation is running.
