Description

Continuous horizontal vacuum band-type filter machine

Technical field

The utility model relates to the separation machinery equipment of solid-liquid material.

Background technology

In some chemical process, particularly wet method prepares in the zinc oxide production, need be with a large amount of water through repeatedly washing repeatedly, drawing liquid, drying, and other composition in the flush away reactant mixture generates zinc carbonate with the reaction of collecting higher degree.Must organize washing pool, filter press, drier in the workshop cycle arrangement more in the past, and, both need a large amount of equipment inputs, also increase labor strength by artificial handling machinery parts, the material of repeating, power consumption, water consumption, and also the shopwork environment is extremely abominable.

Summary of the invention

The utility model purpose is to design a kind of continuous horizontal vacuum band-type filter machine that reduces equipment investment, economize on electricity, water-saving, reduction labor strength.

The utility model mainly is made up of frame, vavuum pump, Drainage tank, circulation filter cloth, great wheel, guide roller, filter disc, feed hopper, drip washing bucket, filter disc is supported on the frame, arrange the suction dish of Drainage tank in the filter disc bottom, offer the hole that is communicated with the suction dish on the filter disc corresponding with the suction dish, the circulation filter cloth is supported on the frame by great wheel and some guide rollers, the segment section of circulation filter cloth is arranged in parallel in the filter disc top, arrange feed hopper, drip washing bucket above this section of circulation filter cloth, vavuum pump is connected with Drainage tank.

The solidliquid mixture material is above feed hopper is distributed in the circulation filter cloth, and by Drainage tank suction dish suction liquid, the flushing of drip washing bucket, the solidliquid mixture material is finished separation simultaneously in the process of advancing.The utlity model has following characteristic:

1, automaticity height.Blanking, filtration, wash, take off slag, filter cloth and clean and be continuous and automatic, the reduction operating cost of enhancing productivity greatly alleviates labor strength, improves working environment.

2, the rate of filtration is fast.Material is by the settling zone, and bulky grain is at bottom, and granule is on the upper strata, and filter cake texture is reasonable, and the penetrating resistance of filtrate is little, can carry out thin layer and filter fast.

3, filtering technique is convenient.Filter cake thickness, leaching requirement, countercurrent washing progression, vacuum, filter cloth speed are adjusted arbitrarily, to reach the optimum filtration effect.

4, clean result is good.Can realize multistage advection or countercurrent washing, the washing uniform and complete, but mother liquor and cleaning solution are according to arts demand separate collection and utilization again.

The delivery port that the utility model is arranged in the Drainage tank at rear portion connects and the drip washing bucket by pipeline, water pump, by recycling part waste water, reduces effective ingredient and runs off, and using water wisely reduces wastewater treatment capacity, further to save production cost.

Description of drawings

Fig. 1 is the utility model structure principle chart

Fig. 2 is the continuous schematic diagram of part-structure

Among the figure, 1 great wheel, 2 copper wire scrapers, 3 frames, 4 filter cloth cleaning devices, 5 roll wheel assemblies, 6 drip washing buckets, 7 filter discs, 8 feed hoppers, 9 fabric clamps, 10 master cylinders, 11 deviation correcting devices, 12 tensioning apparatus, 13 bend wheels, 14 Drainage tanks, 15 guide rollers, 16 material collecting tanks, 17 filter cloth cleaning devices, 18 atmospheric valves, 19 vacuum transfer valves, 20 water pump type vavuum pumps, 21 suction dishes, 22 collecting tanks, 23 countercurrent washing pumps, 24 circulation filter clothes.

Specific embodiment

Section is the filter disc 7 of U type and arranges along the length direction of frame 3 abreast by seven groups of roll wheel assemblies 5.Its length direction of filter disc 7 upper edges is offered four through holes.

Circulation filter cloth 24 is by great wheel 1, fabric clamp, bend wheel and other four guide roller 15 fixed supports, wherein, by great wheel 1 and fabric clamp 9 segment section is arranged in parallel in filter disc 7 tops, at the sliding part that filter disc 7 and 24 layouts of circulation filter cloth of this section are reduced friction, on this assembly connection and the filter disc 7.Simultaneously, on other section of circulation filter cloth 24, be combined with deviation correcting device 11, tensioning apparatus 12.Arrange copper wire scraper 2 above the circulation filter cloth 24 in great wheel 1 the place ahead, at great wheel 1 arranged beneath material collecting tank 16, cooperate filter cloth cleaning device 17 in the both sides of the circulation filter cloth 24 at the rear of great wheel 1, this device can be by cleaning brush and cleaning shower nozzle and collecting pit be formed.
