The disc-type vacuum filter provided by the utility model has the advantages that solid particles in a slurry attach to a filtering disc to form a filter cake by virtue of a magnetic system formed by a magnet and the vacuum action, the dehydration effect is good, the production efficiency is improved, and meanwhile, the service life of filter cloth is more than twice of that of the prior art.

Description

A kind of disk vacuum filter

Technical field

The utility model relates to the strongly magnetic mineral dehydration technique, is specifically related to a kind of disk vacuum filter.

Background technology

At present both at home and abroad, have a lot of ore processing enterprise to adopt disk vacuum filter to carry out the dewatering operation of slurries, this equipment is to the dewatering and filtering poor effect of particulate, subparticle mineral, and filter cake is thinner, exists efficient low, the high defective of water content after the dehydration; Simultaneously this kind disk vacuum filter feed is required and the vacuum requirement high, require feed concentration to be not less than 60%, and feed must be stablized, enough; The filter cloth loss is larger, and production cost is also higher.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of dehydrating effect good, and efficient is high, the disk vacuum filter that the filter cloth loss is low.

To achieve these goals, the technical solution adopted in the utility model is:

This disk vacuum filter comprises filter, main drive gear, agitator, feeder sleeve, guide device for discharging, dispensing head, main shaft and cell body; Main shaft is installed on the cell body, and main shaft connects main drive gear; After filtering cloth bag, the filter suit is connected on the filtrate arm of main shaft; Feeder sleeve and guide device for discharging are located at respectively on the both sides on cell body top; Agitator is located at the bottom of cell body; Two ends at main shaft are provided with dispensing head; Be provided with magnet in described filter both sides.

Described magnet is embedded in the spoke position of filter.

Described magnet field intensity is 63.69A/m – 119.43A/m.

Described filter is fan-shaped.

The utility model has the advantage of: this disk vacuum filter, be provided with magnet in the filter both sides, the solid particle in the slip is borrowed the effect of magnetic system that magnet forms and vacuum to be attached to and is formed filter cake on the filtering table, and dehydrating effect is good; Production capacity improves greatly, and efficient is 1.5-2 times of general disk vacuum filter; The corresponding minimizing of negative pressure of vacuum reaches the effect of electricity saving and energy saving, also can make the filter cloth Service life more than 1 times; Owing to advantages of good adsorption effect, filter cake is even simultaneously, and moisture content is stable, can adapt to each grade strongly magnetic material dewatering and filtering operation.

The specific embodiment

The below contrasts accompanying drawing, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.

As shown in Figures 1 and 2, this disk vacuum filter comprises filter 1, main drive gear 2, agitator 3, feeder sleeve 4, guide device for discharging 5, dispensing head 7, main shaft 8 and cell body 9; Main shaft 8 is installed on the cell body 9 by bearing 6, and main shaft 8 connects main drive gears 2 and by main drive gear 2 driven rotary; Filter 1 is connected on the filtrate arm of main shaft 8, and cover has the filtration cloth bag on the filter 1, is connected on the filtrate arm of main shaft 8 after filter 1 suit filters cloth bag, forms a complete disk; Feeder sleeve 4 and guide device for discharging 5 are located at respectively on the both sides on cell body 9 tops; Agitator 3 is located at the bottom of cell body 9, and agitator 3 prevents that the ore pulp precipitation is fixed; Be provided with dispensing head 7 at the two ends of main shaft 8, dispensing head 7 is responsible for vacuum suction, blowing, filtrate backflow; Be provided with magnet 10 in filter 1 both sides.

As shown in Figures 3 and 4, filter 1 is fan-shaped; Magnet 10 is embedded in the spoke position of filter 1; Magnet 10 field intensity are 63.69A/m – 119.43A/m.

This disk vacuum filter, filtering surface forms several filtering tables by a plurality of independent fan-shaped filters 1 and consists of, be provided with magnet 10 at each fan-shaped filter 1, filter 1 is independent band magnetic filter element, is made by filter cloth and filters cloth bag and be enclosed within on the Fanlike filtrating lamella 1 and form filter chamber; During work, filtering table rotates clockwise, and the solid particle in the slip is borrowed the effect of magnetic system that magnet forms and vacuum to be attached to and formed filter cake on the filtering table; Agitator 3 prevents solids of sedimentation by the transmission mechanism driven rotary; Filter cake leaves after the liquid level, continues to slough moisture content under vacuum action; Filtrate seeing through filtered cloth bag, enters in the filtering table, through filtrate pipe, discharges from dispensing head 7; Filter cake is dried from inside to outside by filter disc at discharge zone and is unloaded; Since increased magnet 10 at filter 1, this disk vacuum filter, production capacity improves greatly, and efficient is 1.5 of general disk vacuum filter---2 times; The corresponding minimizing of negative pressure of vacuum reaches the effect of electricity saving and energy saving, also can make the filter cloth Service life more than 1 times; Owing to advantages of good adsorption effect, filter cake is even simultaneously, and moisture content is stable, can adapt to each grade strongly magnetic material dewatering and filtering operation.

The above has carried out exemplary description to the utility model; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
