Abstract
The invention provides an 82-m<2> vertical disc filtering machine. According to the 82-m<2> vertical disc filtering machine, a pressure difference between two sides of the surface of a filtering disc is utilized so that when aluminum hydroxide slurry passes through filtering cloth on the filtering disc, solid-phase particles are intercepted on the filtering cloth to realize the aim of solid-liquid separation; a filtering period is as follows: a transition region, an adjusting region, a filtering region, a drying region, the filtering region, the transition region and a blowing-off region. The 82-m<2> vertical disc filtering machine has the advantages which are incomparable to other filtering equipment, such as high filtering efficiency, low energy consumption, convenience in mounting and maintenance and the like.
Description
Technical field
The present invention relates to smelt aluminium apparatus field, especially a kind of 82 m
2vertical-disk filter.
Background technology
Vertical-disk filter is for the Separation of Solid and Liquid of aluminum hydroxide slime, and this kind equipment is mainly from external import.82 m2 filters are the needs according to domestic alumina producing, absorbing on the basis of import vertical-disk filter advantage, are bold in innovation, and the equipment of independent development.This equipment not only can be applied in alumina producing, can also be for Jiao processed, papermaking and chemical industry.
Summary of the invention
In order well to meet the needs of industry, the present invention proposes a kind of 82 m
2vertical-disk filter, it is high that it has filter efficiency, and energy consumption is low, the convenient unrivaled advantage of other filter plant that waits of installation and maintenance.
The present invention solves and to ask that the scheme that its technical problem adopts is to utilize the pressure differential of both sides, filtering table surface, and while making the filter cloth of aluminum hydroxide slime by filtering table, solid phase particles is wherein trapped on filter cloth, reaches the object of Separation of Solid and Liquid; Be filter cycle: the transition zone → regulatory region → filtering area → dry section → filtering area → transition zone → district of blowing off.
Above-mentioned 82 m
2vertical-disk filter is comprised of cell body, transmission, filtering table, dispensing head, power transmission shaft, instantaneous blower system.
The beneficial effect of beneficial effect of the present invention is that to have filter efficiency high, and energy consumption is low, the convenient unrivaled advantage of other filter plant that waits of installation and maintenance.

The specific embodiment
Operation principle
82 ㎡ vertical-disk filters are pressure differentials of utilizing both sides, filtering table surface, and while making the filter cloth of aluminum hydroxide slime by filtering table, solid phase particles is wherein trapped on filter cloth, reaches the object of Separation of Solid and Liquid.The negative pressure that the pressure differential of both sides, filtering table surface is produced by vavuum pump maintains, and whole filter process is shown in accompanying drawing 1.Be filter cycle: the transition zone → regulatory region → filtering area → dry section → filtering area → transition zone → district of blowing off.
When power transmission shaft drives filtering table to turn over one week, each chamber in power transmission shaft is communicated with each subregion of dispensing head respectively, thereby generates pair pressure and the malleation on the inside and outside two sides of filtering table, to complete from filtering, be dried to an operation cycle of blowing off.
Structure
Accompanying drawing 2 is shown in by the primary structure of 82 m2 vertical-disk filters.
(1) cell body.Cell body is welded into by steel plate, for hydrogen storage alumina slurry, is again the matrix of filter simultaneously, includes filtrate agitating device and overflow mechanism.
(2) transmission.Driving motor adopts cycloidal-pin wheel reducing motor, is designed to ac variable frequency speed regulation.
(3) filtering table.Filtering table is the mechanism that realizes filtration, complete machine has 4 filter discs, each filtering table consists of some fanning strips, every fanning strip outside is surrounded by one deck filter cloth, produces pressure differential, thereby make the solid phase particles in filtrate on filter disc, form filter cake during work on filter disc two sides, by dry, when filter disc goes to while blowing off district, trigger magnetic valve, the district of blowing off passes into compressed air takes off filter cake.The filtering table of this part is because employing and power transmission shaft is rigidly connected, the rigidity of filtering table is strengthened greatly, and done particular design replacing with of fanning strip and filter cloth, fanning strip and filter cloth are more prone in replacing, have also solved the problem of the less easy generation distortion of current other same category of device filtering table rigidity.
(4) dispensing head.Dispensing head in order to realize filter filter process filtration, be dried, blow off.Power transmission shaft often circles, and wherein each closed chamber is communicated with once with dispensing head Ge district respectively, and closed chamber produces respectively negative pressure and malleation, realizes the function of filtering, being dried, blowing off, and filter just completes filter process one time.
(5) power transmission shaft.Power transmission shaft is for filtrate circulation and the process of blowing off passes into compressed air and drive filtering table to rotate.
(6) instantaneous blower system.Instantaneous blower system forms by taking over solenoid electric valve.On filtering table, form after filter cake, when blowing off district, by related device, start solenoid electric valve, by instantaneous blower system, be blown into the compressed air filter cake that blows off.
Equipment major advantage
(1) simple, filter efficiency is high.Design production capacity in the situation that solid-to-liquid ratio is 700 g/L can reach 130 ~ 150 t/h.The in the situation that of same solid-to-liquid ratio, can substitute the production capacity of two 40 ㎡ rotary drum filters.
(2) driven Design adopts frequency control and cycloidal planetary gear speed reducer, and transmission efficiency is high, and stepless speed regulation can be adjusted the rotating speed of filtering table aborning according to actual needs very easily, thereby reaches the object of adjusting production capacity.
(3) when offering overfall overflow, than domestic other similar devices, increased fluid level control device, when user uses, can select to control or fluid level control device control with overfall.
(4) solved domestic existing vertical-disk filter and existed filtering table change difficult and easily produce the problem of distortion, made to change fanning strip convenient.The form special to the fixedly employing of filtering table, increases the structural rigidity of filtering table.Fanning strip adopts rigidity contact with being connected of power transmission shaft, and bonding strength increases, and can change separately fanning strip.
(5) the filter pipe of annular seal space and cross sectional shape have been done to optimization, made filtrate emptying better with the effect of supplying gas pulse compression air.
