The structure of belt filter press

The structure of belt filter press

Belt press filter is mainly composed of drive device, frame, press roller, upper filter belt, lower filter belt, filter belt tensioning device, filter belt cleaning device, discharging device, air control system and electrical control system.China has a large industrial chain, low production concentration, low research and development capability of high-end products, and low manufacturing technology level of belt filter press industry.The next few years will be a period of high speed shock in the belt filter press  industry, and the direct consequence of this high speed shock is the expansion of polarization in the camp.Not many companies are expected to actually survive in the market in the next few years.But the high speed of the belt filter industry will bring great opportunities, and the result of the shock will make the market operation more rational.


The road to localization of high-end electric power is "bumpy".Components has become our country industry belt type filter press to high-end development, during the twelfth five-year government will continue to increase the belt type filter press high-end equipment parts and components of some well-known enterprises also stand out product has been widely used in environmental protection, municipal, mining, power, chemical industry, electronics, food, pharmaceutical, textile and so on all walks of life.


The following is a brief introduction of the structure and working status of the main components:dewatering belt press 

1 rack: the belt press filter rack is mainly used to support and fix the press roller system and other parts.

2. dewatering belt press,Crushing roll system: it is composed of a roll barrel arranged in order from big diameter to small diameter.When the sludge is clamped by the upper and lower filter belts and passed through the press roller in turn, a pressure gradient from small to large is formed under the action of the filter belt tension. As a result, the crushing force of the sludge in the dewatering process is continuously increased, and the water content in the sludge is gradually removed.

Gravity dewatering device: mainly consists of gravity zone bracket and material trough.After flocculation, the material will remove a lot of water in the gravity zone, and its mobility will become poor, creating conditions for subsequent extrusion and dehydration.


4 dewatering belt press,wedge dewatering device: the wedge area formed by the upper and lower filter belt imposes squeeze pressure on the materials held, and performs pre-pressure dewatering to meet the requirements of the liquid content and fluidity of the materials in the squeeze dewatering section.

5 dewatering belt press,filter belt: it is the main part of belt type press filter. The separation process of solid phase and liquid phase of sludge is above. The lower filter belt is the filter medium.

6 filter belt adjustment device: consists of actuator: cylinder, adjusting roller signal anti-pressure, and electrical system.Its function is to adjust the deviation of the filter belt caused by uneven tension of the filter belt, error of roller installation and uneven feeding, so as to ensure the continuity and stability of the belt press filter machine.


7. dewatering belt press,Cleaning device for filter belt: consists of sprinkler, cleaning water junction box and cleaning cover, etc.When the filter belt is moving, it will continuously go through the cleaning device and be impacted by the pressure water spurted by the sprinkler, and the material remaining on the filter belt will break away from the filter belt under the action of pressure water, so as to regenerate the filter belt and prepare for the next dehydration process.

8.dewatering belt press, Filter belt tensioning device: composed of tensioning cylinder, tensioning roller and synchronous mechanism, the function of which is to tighten the filter belt and provide necessary tension conditions for the production of the pressing force for dehydration.

Unloading device: consisting of scraper plate, knife rest and discharging roller, the function of which is to peel off the dehydrated filter cake and filter belt to achieve the purpose of unloading.

10 dewatering belt press,transmission device: composed of motor, reducer, gear transmission mechanism, etc., it is the power source of filter belt travel and can meet the requirements of different belt speeds by adjusting speed of reducer.

Air pressure system: the system is mainly composed of power sources (gas storage tank, motor, air pump, etc.), actuating components (cylinder) and air pressure control elements (including pressure relay, pressure flow and direction control valve).Control the air pressure, flow and direction through the air pressure control element, ensure that the air pressure actuator has a certain thrust and speed, and work as scheduled.It is the power source of the filter belt tension and adjustment operation.
