Improvement and upgrade of belt filter press system

        Improvement of the pneumatic device of the belt filter press and the rubber roller system of the filter press
1. Pneumatic device
The filter belt of the old-fashioned belt filter press uses double cylinders to correct deviation, and only the lower filter has a filter belt limit switch to protect the filter belt from deviation. We found in actual operation experience that the double cylinder correction is obviously better than the single cylinder in correction effect. The correction effect is better. However, the use of a single cylinder to correct deviation can also meet the equipment operation, but the adjustment response is slightly slower. After the improvement, one end of the filter belt adopts a correction cylinder to correct the deviation, and the other end adopts a screw adjustment structure, which is adjusted according to the on-site operation. The upper filter belt limit switch is added to protect the filter belt, extend the service life of the filter screen, and increase the flexibility of the equipment.

2. Rubber roller system
The old-fashioned belt filter press pattern roller device is made of angle steel, which is convenient for squeezing the water out, but it damages the filter screen. Since the pressing surface is the top of the angle steel, the contact form between the filter belt and the angle steel is line contact, which will cause aggravation The wear of the filter belt reduces the life of the filter belt. In addition, since the welds of angle steel and steel pipes are exposed to air and sewage, the welds may corrode more severely. Once the angle steel falls off due to weld corrosion, the belt filter press will be severely damaged.
After the improvement, the welding angle steel outside the steel pipe is now removed, but it may affect the squeezed water. However, according to the actual operating conditions on site, most of the water still passes through the filter belt or is removed from both sides of the filter belt. If you want to consider better results, you can drill holes on the surface of the pressure roller to achieve the desired effect, and this will not affect the service life of the filter belt.
