Description

A kind of Vacuum filtration device

Technical field

The utility model discloses the technical field for being related to vacuum filter more particularly to a kind of Vacuum filtration device.

Background technique

Vacuum filtration device is the equipment of realizing separation of solid and liquid using negative pressure of vacuum as motive force.The basic principle is that: true Under the action of idling pressure, the penetration by liquid filter medium (filter cloth) in slurry is taken away, and the solid particle in slurry is then by mistake Filter medium is retained, to realize the separation of liquid and solid.Vacuum apparatus is widely used in the iron of mine concentration In multiple industries such as the filtering of the products such as concentrate, delafossite, iron concentrate and zinc concentrate and chemical industry, petroleum, metallurgy and papermaking.

Currently, Vacuum filtration device is broadly divided into three classes, it is respectively as follows: Horizontal disc Suction filtration device, tilting pan type filters dress It sets and vertical disc Suction filtration device.In summary three classes Suction filtration device is primarily present following problem:

1 takes up a large area

Filtering surface in Horizontal disc Suction filtration device and tilting pan type Suction filtration device is the horizontal filtering face of single layer, and The occupied area of whole equipment is greater than filter area, under conditions of identical filter area, Horizontal disc Suction filtration device and The occupied area of tilting pan type Suction filtration device will be far longer than vertical disc Suction filtration device, and therefore, the defect taken up a large area is serious Limit the use of Horizontal disc Suction filtration device and tilting pan type Suction filtration device.

2) structure is complicated, high failure rate

Horizontal disc Suction filtration device is provided with multiple trapezoidal filter discs, during suction filtration, synchronization, and each trapezoidal filter Disk is in different processes, and each filter disc will complete the suction filtration processing of a batch slurry, be both needed to rotate horizontally one week, because This, corresponding above-mentioned working method, each Horizontal disc Suction filtration device be both needed to setting center it is vertical lean on, center distributing valve (wrong gas Disk), turntable turntable, guide rail, rotating members and the dynamic seal joint such as support roller, and excessive rotating member will lead to the abrasion of whole equipment Probability rises, and a large amount of dynamic seal joint also will increase gas leakage probability and air leakage, high failure rate.Wherein, tilting pan type filters dress It sets and there are similar problems with vertical disc Suction filtration device, just do not illustrate one by one herein.

3 there are index conflicts, inaccurate coordination

The discharge way of Horizontal disc Suction filtration device is: outer ring rubber strip by belt gear wheel and annular filter outer rim from It opens, forms a discharge port, the filter cake on filtering surface is pushed into dump skip with rapid spiral slag separator from inner ring to outer rim.This Kind discharge way is almost unavoidable causes discharge auger to generate more serious damage to filter cloth, especially when filter cake discharging spiral shell When rotation is too small with filter disc plane clearance, filter cloth is easily scratched, filter cloth is caused to lead to hole breakage and cause vacuum and slurry and wash water short Road increases solid content in filtrate, is filtered, washed efficiency reduction；And if in order to reduce filter cloth abrasion and by filter cake discharging spiral shell Rotation and filter disc plane clearance adjust to it is excessive when, and will lead to a large amount of slags and form stratiform on filter disc and retain, filter disc is difficult to rinse Completely, cause the reduction of filter cloth porosity, influence intensity filter and detersive efficiency, and requirement of the filter cloth washing water to water quality and hydraulic pressure Height, failure rate are relatively high.

Although tilting pan type Suction filtration device is overturn using filter disc, can overcome water by " gravity " and " blowback power " progress discharging The problem of abrasion of filter cloth existing for flat round disc type Suction filtration device or blocking, but since every filter disc will overturn, deslagging, flushing, Radial journal bearing seat need to be set by inner and outer ends and control the flip-arm roller of filter disc overturning, therefore, every filter disc will increase by 4~5 A rotatable parts, and the quantity of rotatable parts increases, and will lead to the decline of equipment reliability of operation, high failure rate, maintenance process Middle filter cloth replacing difficulty increases, and the occupied area of equipment can also further increase.

, can for although vertical disc Suction filtration device is compared to Horizontal disc Suction filtration device and tilting pan type Suction filtration device Largely reduce occupation area of equipment, but due to filtering surface be it is vertical, when handling non-viscous material, filter cake became uneven, easy tortoise Split, detersive efficiency it is low, and thin layer filter cake unloading difficulties, filter cloth quick abrasion, easily blocking, high failure rate.

4 working efficiencies are low

Above-mentioned Horizontal disc Suction filtration device, tilting pan type Suction filtration device and vertical disc Suction filtration device, all has one A identical feature, it may be assumed that in a rotation period of entire filtering surface, different subregions is in different works on filtering surface Make the stage, therefore, the completion course of work that different subregions cannot synchronize on filtering surface, and this feature is effectively equivalent to roll over Filter area is subtracted, has inevitably resulted in efficiency and decline to a great extent.
