Du Rubber Belt Vacuum Filter

DU Rubber belt vacuum filter is equipment using vacuum negative pressure as impetus to separate the solid and liquid. The filter district is arranged levelly to sequentially finish the procedure of filter, rinse, dry and regeneration of the filter cloth with high efficiency, high rinsing effect, low moislure, agile operation and low repair cost. It can be used to separate solid and liquid in the fields of metallurgy, mine, chemical industry, papermaking, food, pharmacy and environmental protection, especially for dehydration of gypsum in the process of smoke desulfurization.

On the basis of inducing foreign technology of the same kinds products, rubber belt vacuum filter is a kind of high efficient solid-liquid separating equipment through our research. It adopts setting vacuum chamber and the rubber belt moves on vacuum chamber. Vacuum chamber and rubber belt form a structure of moving and sealing. It in fact has realized continuous filtering, make clearing, residue unloading and filter fabrics cleaning and collecting the mother liquid and make cleaning efficient, low make water, operation smart, maintenance simple and so on. Rubber Delt Filter has experienced many times of improvement and perfection, the technology and quality has been the international advanced level. It has been widely used in sectors such as metallurgy, mining, chemical, engineering, paper making, food, pharmacy and environment protection.

Structural technical feature
Which can accomplish feeding, filiation, make washing, sit up, make discharge, cloth wash technics operation continuously
The mother filtrate and other washing filtrate can be collected in different subsection. Meanwhile the washing can be in current washing and countercurrent washing way.
It is flexible to assemble equipment because of the modular structure and convenient for the transportation and installation
It is convenient to remote automatic control and scene control for DCS
Vacuum box and lift-fall device
(lift-fall device )
(Life-fall device)
Vacuum box adopts separate sections; Each section has the nozzle connection to the collection liquid pipe, forming the vacuum system, It has designed a lift-fall device, convenient to replace the friction bell
Deviation-rectifying device
Cylinder deviation-rectifying
Air-bag-rectifying
Adopt cylinder or air-bag to move a angle of the deviation-correcting roller. Achieve correcting the deviation of the filler cloth, make sure the filter cloth run correctly.
Rubber tension device
Rubber Tension Device
Rubber tension device adjust the tension of the rubber belt by the screw, make sure the enough friction and no-deviation running
Washing device
Washing device

Uses the craft water to spray, washing the filter cloth and the rubber belt, and have the vacuum sucker seal box. By the way, guarantee the clean job site and the rubber belt filter machine work normally. The nozzle uses the product of the American atomization company, many fully guarantee the clean washing effect
Material spraying wash craft
Countercurrent washing sketch
(Current washing sketch)
Adopt the countercurrent spray washing and the spout spray washing. According to the material and the craft requirement, it can use the countercurrent of the current washing for the better effect.
Rubber belt support device
( Rubber Belt Support Device)
Rubber belt adopts air bag or water film supporting. The rubber belt floats on air bag, reducing moving resistance and good for prolong the service life or rubber belt.
