Printing and Dyeing Industry Belt Filter Press for Sludge Dewatering with 500mm Filter Belt Width

Fully Automatic Belt Filter Press 500mm Filter Belt Width Sludge Dewatering Belt Press

 

 

DY series belt filter press is the national research institutes with the introduction of foreign advanced technologies based on the successful development of new models, widely used in urban waste water treatment, chemical, oil refining, metallurgy, paper, leather, food, coal washing, printing and dyeing industry, sludge dewatering. Machine continuous operation, high degree of automation, energy saving, high efficiency, easy maintenance, is ideal for sludge dewatering equipment.

 

The belt press filter mainly consists of a driving device, a frame, a press roll, an upper filter belt, a lower filter belt, a filter belt tensioning device, a filter belt cleaning device, a discharging device, an air control system, and an electrical control system.

 

1 Frame: The belt press filter frame is mainly used to support and fix the press roller system and other components.

 

2 Press roller system: It consists of rollers with diameters arranged in order from large to small. The sludge is held by the upper and lower filter belts. When it passes through the press rollers in sequence, a pressure gradient from small to large is formed under the tension of the filter belt. Water is gradually removed.

 

3 Gravity zone dewatering device: It is mainly composed of gravity zone bracket and hopper. The flocculated material removes a large amount of water in the gravity area, and the fluidity becomes poor, which creates conditions for subsequent extrusion dehydration.

 

4 Wedge-shaped zone dewatering device: The wedge-shaped zone formed by the upper and lower filter belts exerts a pressing force on the clamped material and performs pre-pressure dehydration to meet the requirements for the liquid content and fluidity of the material in the squeeze dewatering section.

 

5 Filter belt: It is the main component of the belt press filter. The solid and liquid phases of the sludge are separated above and below. The lower filter belt is the filter medium. The upper and lower filter belts are tensioned to bypass the squeeze. Roller to obtain the pressing force required to remove material moisture.

 

6 Filter belt adjusting device: It is composed of executive components: air cylinder, adjusting roller signal back pressure, and electrical system. Its role 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., thereby ensuring the continuity and stability of the belt press filter.

 

7. Filter belt cleaning device: It consists 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 from the shower. ready.

 

8. Filter belt tensioning device: It consists of a tension cylinder, a tension roller and a synchronization mechanism. Its role is to tension the filter belt and provide the necessary tension conditions for the production of the pressing force of the dewatering press. This can be achieved by adjusting the air pressure of the tensioning cylinder of the air pressure system.

 

9 Unloading device: It consists of scraper plate, knife holder, unloading roller, etc. Its function is to peel the dehydrated filter cake and filter belt to achieve the purpose of discharging.

 

10 Transmission device: It is composed of motor, reducer, gear transmission mechanism, etc. It is the source of power for filter belt running, and can adjust the speed of the reducer to meet the requirements of different belt speeds in the process.

 

11 Pneumatic system: This system is mainly composed of a power source (gas storage tank, motor, air pump, etc.), executive components (cylinders), and pneumatic control components (including pressure relays, pressure flow and directional control valves). The air pressure control element controls the air pressure, flow rate and direction to ensure that the air pressure actuator has a certain thrust and speed, and works normally according to a predetermined procedure. It is the source of power to complete the tensioning and adjustment of the filter belt.
