Abstract
The utility model discloses a defoaming device for a center driving thickener. The defoaming device comprises a steel pool and a bridge rack at the upper end of the steel pool; a floating ring is hung at the lower end of the bridge rack and comprises a plurality of floats arranged in a circle; the floats are wrapped with canvas sleeves respectively; a heavy is hung at the bottom of each floating ring. The defoaming device is simple in structure; foam gathers in the floating ring and cannot flow out of the floating ring, and when the concentration of the foam reaches a critical point, the foam can break and join ore slurry again, so that the purpose of defoaming can be achieved, foam on the liquid surface can be eliminated effectively, and washing water is protected from being polluted.
Description
Technical field
The utility model relates to the thickener field, specifically a kind of defoaming device of central transmission concentrator.
Background technology
At industry-by-industry tail muddy water such as coal, metallurgy, chemical industry, environmental protection, process on this link, be mainly used in thickener concentrated and clarification and become one of key equipment of extensive use, its be mainly utilize sedimentation theory that the solid particle in ore pulp is deposited to the pond of thickener at the bottom of, clarified solution is gone out from the downflow weir overflow, to realize Separation of Solid and Liquid.
At thickener, process in the process of mine tailing, the liquid level foam is extremely many, after entering thickener, and a part of foam nature froth breaking, another part enters wash water with the thickener overflow.Due in foam with the mineral matter of particulate, make wash water receive pollution, wash water concentration increases.After being with frothy wash water to enter circulating water pool, easily make water circulating pump have gas, cause the ore deposit amount to reduce.These problems have badly influenced the work quality of thickener.And the project organization of traditional thickener is short of to some extent aspect treatment fluid papula foam always, thereby concentrated quality can't be got a promotion.
The utility model content
The purpose of this utility model is to provide a kind of defoaming device of central transmission concentrator, allows foam enrichment in cursory circle, after consistency of foam arrives critical point, can fragmentation reintegrate in ore pulp, to reach the purpose of froth breaking.
The technical solution of the utility model is as follows:
A kind of defoaming device of central transmission concentrator, include steel pond and the crane span structure that is positioned at upper end, steel pond, it is characterized in that: the lower end of described crane span structure is hung with cursory circle, it is cursory that described cursory circle includes several that form a circle, described several cursory outsides are coated with respectively the canvas cylinder, and the bottom of described cursory circle is hung with weight.
The defoaming device of described central transmission concentrator is characterized in that: described weight is iron chains.
The beneficial effects of the utility model:
The utility model is simple in structure, and foam enrichment is in cursory circle, and foam just can not flow out outside cursory circle in cursory circle, after arriving critical point, consistency of foam can fragmentation reintegrate in ore pulp, reached the purpose of froth breaking, can get rid of timely and effectively the liquid level foam, guaranteed that wash water is not contaminated.
The accompanying drawing explanation
The front view that Fig. 1 is the utility model structure.
The top view that Fig. 2 is the utility model structure.
The specific embodiment
Referring to Fig. 1,2, a kind of defoaming device of central transmission concentrator, include steel pond 1 and the crane span structure 2 that is positioned at 1 upper end, steel pond, the lower end of crane span structure 2 is hung with cursory circle, cursory circle include form a circle several cursory 3, several outsides of cursory 3 are coated with respectively the canvas cylinder, and the bottom of cursory circle is hung with iron chains 4.
The height of cursory circle is about 800mm, the height that wherein is positioned at the above part of steel pond 1 liquid level is 500mm, the height that is positioned at the following part of steel pond 1 liquid level is 300mm, is equivalent to the interior downflow weir that added in steel pond 1, and foam just can directly not flow out cursory circle in cursory circle like this.
Claims (2)
1. the defoaming device of a central transmission concentrator, include steel pond and the crane span structure that is positioned at upper end, steel pond, it is characterized in that: the lower end of described crane span structure is hung with cursory circle, it is cursory that described cursory circle includes several that form a circle, described several cursory outsides are coated with respectively the canvas cylinder, and the bottom of described cursory circle is hung with weight.
2. the defoaming device of central transmission concentrator according to claim 1, it is characterized in that: described weight is iron chains.
