Detailed introduction

Belt filter press manufacturer-Chongqing Wolik Environmental Protection Equipment Co., Ltd.


Structure introduction

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.


Briefly introduce the structure and working status of each major component :

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

2Squeezing 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, which makes the pressing force of the sludge during the dehydration process continuously increase, and the sludge Water is gradually removed.

3 Gravity zone dewatering device: It is mainly composed of gravity zone bracket and trough. 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 dewatering 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 a 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 belt tension forces 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 dehydration press. This can be achieved by adjusting the air pressure of the tensioning cylinder of the air pressure system.

9 discharge device: consists of scraper plate, knife holder, discharge roller, etc., its role is to peel off the dehydrated filter cake and filter belt to achieve the purpose of discharging.

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

11 Air pressure system: This system is mainly composed of power source (gas storage tank, motor, air pump, etc.), executive components (cylinder) and air pressure control elements (including pressure relay, pressure flow and directional control valve). 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.


classification

1 According to the material and equipment structure of the frame and drum, it can be divided into heavy carbon steel belt filter press and light stainless steel belt type concentrated dehydration machine.

Heavy-duty carbon steel belt filter press frame with large size, long gravity dewatering zone, large roller diameter, both frame and roller are made of carbon steel for heavy anti-corrosion treatment, large sludge treatment capacity, sufficient pressing, and filter cake with water The rate is low.

The frame and rollers of the light stainless steel belt type concentration and dehydration integrated machine are made of stainless steel. It consists of a sludge mixer, a drum (belt) thickener and a belt filter main unit. With a small footprint, it is suitable for medium and low concentration sludge treatment.
