Working Principle:
The above figure shows the working principle of a belt filter. Slurry in the feeding box A is evenly distributed on the forwarding filter cloth I. Driven by the vacuum force, filtrate passes through the filter cloth and enters the vacuum box J along the discharge slot of rubber belt H. The filtrate then enters into the gas and liquid separation system through the filtrate pipe for collection, discharge or recycling. The filtrate residue left on the filter cloth is formed a filter cake before discharging. After discharge, the filter cloth passes the washing device D and then enters the next-cycle filter. The filter can collect filtrate and washing solution respectively. The filter cake can be washed in a downstream or an upstream manner (see the figure) and the belt speed can be adjusted as required within a range. The whole slurry feeding, filter, washing, drainage, discharge and cloth washing process is auto-completed and can be remotely controlled.
Wear Belt:
Friction belt: it adopts SBR rubber, with four layers of EP200 polyester reinforcing layer, endless type, and the surface contacting with the slideway is EP400 polyester, which can effectively reduce the frictional resistance and prolong the service life. The main roles of the friction belt are to avoid the direct contact of the rubber belt with the vacuum slideway, to extend the service life of the rubber belt and simultaneously reduce the frictional force. The main structures are that: the surface contacting with the rubber belt is rubber layer, in order to increase the frictional force and ensure that the rubber belt and friction belt are in synchronous running; the surface contacting with the vacuum slideway is EP400 cloth, in order to reduce the frictional force with the vacuum slideway; the structure is endless, with a total of four layers of EP200 cloth, to ensure the tensile strength. The friction belt thickness should be uniform, without joints in the middle. The friction belt thickness: 10 mm, width: 50 mm, and tensile strength: 50000 N.
The technical parameters are as follows:
Thickness: 10 mm
Width: 50 mm
Tensile strength: 50000 N
Rubber Curb:
Flat or ripple curbs with different material: SBR,NR,EPDM...
Tensile strength is high and service life is long.
Rubber pulleys
Each filter is equipped with a drive pulley and a driven pulley; the cylindrical surface and lateral surface are covered by SBR rubber. For the drive pulley, the rubber layer thickness is no less than 30 mm, while the thickness is 16 mm at the tip, with the hardness of 65 degrees. For the driven pulley, the rubber layer thickness is 25 mm. V-shaped grooves are carved on the rubber layer of the drive pulley, to drain the excess fluid and increase the adhesive force of the rubber layer. The service life is up to 100,000 hours. The design and manufacture of all rollers (including the rubber belt support roller, the filter cloth supporting, bend and tension rollers, the filter cloth press roller, and the cloth flattening roller) are of low bending stress, that is: the roller does not bend during load running; the bearings of all rollers adopt self-positioning double-seal ball bearings, and simultaneously the sealing effects are fully taken into account, the mother liquid is not allowed to enter the bearing body. The structure that the bearing body is placed externally and fixed on the framework is not recommended.
Rubber belt support roller: The invention patent technology (ZL96115855.7) is used. The roller material is plastic alloy. Built-in design and labyrinth design are employed in the bearing, to ensure that the bearing is not corroded by atmosphere and penetration, which can greatly improve the bearing life.
Rubber belt support roller It uses Q235 seamless pipe, with SBR rubber covered on the surface and the rubber thickness is 20 mm. For the rubber-covered roller, the diameter of DU-72 m2/3200 is φ345. Both ends of the roller are connected to the framework with bearings and one-piece sealed bearing support. The bearings adopt heavy series double-row self-aligning roller bearings.
Filter cloth press roller It is mounted in front of the feeding hopper, and its role is to ensure the effective integration of the filter cloth and rubber belt before the filter cloth entering the feeding hopper. The material is Q235 lining plastic. It is of tapered design at both ends, with a diameter of φ325.
