Description
Technical field
A kind of horizontal vacuum belt filter with filter plate dredger, relate to a kind of in food, chemical industry, metallurgy industry production, be specially adapted to the improvement of the horizontal vacuum filter evaporating the Separation of Solid and Liquid process such as salt discharge, multiform alumina production in alumina producing.
Background technology
In chemical metallurgy is produced, test of belt vacuum filter is that hydrometallurgy produces conventional a kind of solid-liquid separating equipment, it is the filter plant that a kind of automaticity is high, this equipment mainly with filter cloth or filter screen for medium, make slip horizontally disposed on filter medium, make full use of slip gravity and pull of vacuum realizes Separation of Solid and Liquid.
Along with the development of aluminum oxide technology, for reaching economize energy, reducing the object consuming, reduce alumina production cost, in Bayer process production system, carbon alkali in system is belonged to inactive alkali, carbon alkali in system is discharged by general salt discharge operation of will passing through in process of production, to improve evaporator effectiveness, reduction system carbon alkali ratio, and horizontal vacuum belt filter is exactly the capital equipment of salt discharge operation.
In process of production, sodium carbonate, the sodium sulphate solubility in circulating mother liquor raises along with the rising of temperature, reduce along with the rising of mother liquid concentration, mother liquid evaporation is after pervaporation forces effect to concentrate further, Ke alkali and full alkali concn constantly rise, and the sodium carbonate in solution is in hypersaturated state just crystallization.Horizontal belt filter is can by catching, solid particles by one, the process that solid particle is separated from suspension by the porous media that liquid can be made again to pass through, its operation principle injects in half slot by sedimentation underflow, by vacuum system, filtrate is sucked vacuum by flow container, self-pressure enters overflow launder, mother liquor tank is delivered to by flood pump, the crystal grain such as sodium carbonate, sodium sulphate is filtered cloth and is trapped in drum surface formation filter cake, blots, has laid down filter process, pour filter cake groove with carbon mother liquid again, prepared burden toward sintering process system from filter cake pumping.
In process of production; band filter filtrate card often can block; the crystal salt such as sodium carbonate, sodium sulphate removing blocking filter plate is very difficult; have impact on the life cycle of band filter; filter production capacity can be caused to reduce because filter plate blocking scabs, or the production accident that band filter kills.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for above-mentioned prior art, a kind of effective crystal salt such as sodium carbonate, sodium sulphate removing blocking filter plate is provided, extend life cycle, improve production capacity, avoid the horizontal vacuum belt filter of the band filter plate dredger of production accident.
The purpose of this utility model is realized by following technology.
With a horizontal vacuum belt filter for filter plate dredger, its structure comprises filter body, filtrate card, filtrate pipe, vacuum by flow container, vavuum pump, water spilage tray, tubing pump and water tank; It is characterized in that:
(1) be connected with high-pressure water pipe at each filtrate pipe, this high-pressure water pipe is provided with water under high pressure valve;
(2) valve is provided with by flow container by liquid pipe in vacuum;
(3) vacuum are subject to arrange isolating valve between the filtrate pipe of flow container connection.
A kind of horizontal vacuum belt filter with filter plate dredger of the present utility model, connects with water under high pressure water main after it is characterized in that the described high-pressure water pipe parallel connection connected at each filtrate pipe, water under high pressure water main is provided with total valve.
A kind of horizontal vacuum belt filter with filter plate dredger of the present utility model, when cleaning band filter filtrate card, effectively the crystal salt such as sodium carbonate, sodium sulphate of blocking filter plate can be washed out, the life cycle of band filter can be extended, avoid completely because filter plate blocking scabs and cause filter production capacity to reduce, or the production accident that band filter kills.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
With a horizontal vacuum belt filter for filter plate dredger, its structure comprises filter body 1, filtrate card 2, filtrate pipe 3, vacuum by flow container 4, vavuum pump 5, water spilage tray 6, tubing pump 7 and water tank 8; Be connected with high-pressure water pipe 9 at filtrate pipe, this high-pressure water pipe is provided with water under high pressure valve 10; Valve 11 is provided with by flow container by liquid pipe in vacuum; A vacuum is subject to arrange isolating valve 12 between the filtrate pipe of flow container connection.
A kind of horizontal vacuum belt filter with filter plate dredger of the present utility model, connects with water under high pressure water main 13 after the described high-pressure water pipe parallel connection connected at each filtrate pipe, water under high pressure water main is provided with total valve 14.
Below in conjunction with accompanying drawing and example, the utility model is described.
A kind of horizontal vacuum belt filter with filter plate dredger of the present utility model, install the valve of a φ 100mm at band filter head water under high pressure valve additional, and lay the pipeline of φ 100mm to each subregion of band filter filter plate and install water under high pressure valve additional.Be provided with the high-pressure water pipe be connected with filtrate pipe, add valve between each filter plate subregion to cut off, only need close entering vacuum by tank valve when rinsing filter plate, open the water under high pressure valve of respective partition, water under high pressure will carry out back flush by the filtrate pipe of respective partition to filtrate card, can clean the filter plate of local stoppages and without the need to closing down band filter, greatly save manpower and materials, improve the running rate of band filter.
