Structure and product analysis of belt filter press

     Structure and product analysis of belt filter press:

With the rapid economic development and the improvement of the level of science and technology, it has brought material abundance to people, but also brought serious pollution to the environment. Therefore, it is very important to do environmental protection work in the process of development. The large amount of waste water and residue produced by the factory needs to be processed by efficient environmental protection equipment. The belt filter press is one of them. Below we will explain the structure of the belt filter press.

Belt filter is mainly composed of driving device, frame, press roll, upper filter belt, lower filter belt, filter belt tensioning device, filter belt cleaning device, unloading device, air control system, electrical control system, etc.
1. Frame: The belt press filter frame is mainly used to support and fix the press roll system and other components.
2. Press roller system: It is composed of rollers arranged in order from large to small in diameter. The sludge is clamped by the upper and lower filter belts, and when it passes through the press rollers in turn, a small to large pressure gradient is formed under the action of the filter belt tension, which makes the squeezing force of the sludge continuously increase during the dewatering process. The middle moisture is gradually removed.
3. Gravity zone dehydration device: mainly composed of gravity zone bracket and material trough. The flocculated material loses a large amount of water in the gravity zone, and its fluidity becomes worse, creating conditions for the subsequent extrusion and dehydration.
4. Wedge-shaped zone dehydration device: The wedge-shaped zone formed by the upper and lower filter belts exerts squeezing force on the clamped materials and performs pre-pressing dehydration to meet the requirements of the squeezing and dewatering section for the liquid content and fluidity of the materials.
5. Filter belt: It is the main component of the belt press filter. The separation process of the solid phase and liquid phase of the sludge are both the upper and lower filter belts as the filter medium, which is bypassed under the tension of the upper and lower filter belts. Press rolls to obtain the pressing force needed to remove moisture from the material.

6. Filter belt adjustment device: It is composed of executive components: air cylinder, adjusting roller signal back pressure, and electrical system. Its function is to adjust the deviation of the filter belt caused by various reasons such as uneven filter belt tension, roller installation error, uneven feeding, etc., so as to ensure the continuity and stability of the belt press filter.
7. Filter belt cleaning device: It is composed of a sprayer, a cleaning water contact box and a cleaning cover. When the filter belt is walking, it continuously passes through the cleaning device, and is impacted by the pressure water sprayed by the sprayer. The material remaining on the filter belt is separated from the filter belt under the action of the pressure water, so that the filter belt is regenerated for the next dehydration process. ready.
8. Filter belt tensioning device: It is composed of a tensioning cylinder, a tensioning roller and a synchronization mechanism. Its function is to tension the filter belt and provide the necessary tension conditions for the production of the pressing force for the pressing and dewatering. The tension is adjusted This can be achieved by adjusting the air pressure of the tension cylinder of the air pressure system.
9. Unloading device: It is composed of scraper plate, knife holder, unloading roller, etc. Its function is to peel off the dewatered filter cake from the filter belt to achieve the purpose of unloading.
10. Transmission device: It is composed of motor, reducer, gear transmission mechanism, etc. It is the power source for the filter belt to travel, and can meet the requirements of different belt speeds in the process by adjusting the speed of the reducer.
11. Air pressure system: The system is mainly composed of power source (air tank, motor, air pump, etc.), executive components (cylinder) and air pressure control components (including pressure relay, pressure flow and direction control valve). Through the air pressure control element, the air pressure, flow and direction are controlled to ensure that the air pressure actuator has a certain thrust and speed, and works normally according to the predetermined program. It is the power source to complete the filter belt tensioning and adjustment operations.
