Abstract
The utility model discloses a rotational flow feed device for a center transmission thickener. The rotational flow feed device for the center transmission thickener comprises a feed pipe communicated with the center transmission thickener and further comprises a feed well. An upper layer spiral feed channel and a lower layer spiral feed channel are arranged in the feed well. The spiral directions of the two spiral feed channels are reverse. A plurality of inclined cutters are arranged in each spiral feed channel. The upper layer spiral feed channel and the lower layer spiral feed channel are respectively communicated with two distributing pipes. The two distributing pipes are respectively communicated with the feed pipe. The rotational flow feed device for the center transmission thickener is scientific and reasonable in structure. Due to arrangement of the distributing pipes entering into the feed pipe, feed speed of ore pulp is decreased, effect of flocculating agent can be expressed to a maximum degree, so that flocculation efficiency is improve and cost is reduced.
Description
Technical field
The utility model relates to a kind of feeding structure, mainly is the eddy flow feeding device on a kind of central transmission concentrator.
Background technology
Thickener is applicable to the concentrate and tailings processed in ore dressing plant, is widely used in the industries such as metallurgy, chemical industry, coal, nonmetal ore-dressing, environmental protection.It mainly is to utilize sedimentation theory the solid particle in the ore pulp to be deposited at the bottom of the pond of thickener, and clarified solution is gone out from the downflow weir overflow, realizes Separation of Solid and Liquid.
In the process of thickener work, in order to improve thickening efficiency, usually in ore pulp, add a certain amount of flocculant, make the ore particle in the ore pulp form floc sedimentation, accelerate its sinking speed., traditional thickener only has a feed pipe, and the charging rate of ore pulp is fast during work, kinetic energy is large, can not effectively mix with flocculant, makes flocculating effect not reach best state.
The utility model content
Technical problem to be solved in the utility model provides the eddy flow feeding device on a kind of central transmission concentrator, it is scientific and reasonable for structure, being provided with isocon enters in the feed pipe, reduce the charging rate of ore pulp, can at utmost bring into play the effect of flocculant, improve flocculation efficiency, reduced cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Eddy flow feeding device on a kind of central transmission concentrator, include the feed pipe that is communicated with on central transmission concentrator, it is characterized in that: also include a reinforced well, be provided with upper and lower two helical layer feeding-passages in the reinforced well, the hand of spiral of two spiral feeding-passages is opposite, be provided with the section of a plurality of inclinations in the described spiral feeding-passage, described upper and lower two helical layer feeding-passages are communicated with two sub-feed tubes respectively, and two sub-feed tubes all are communicated with feed pipe.
Described reinforced well is welded to connect on the bottom of a crane span structure by a plurality of supporting legs, and described feed pipe is hung in the crane span structure bottom by hanging the bar welding.
Feed pipe is divided into two charging apertures by a charging aperture by two isocons in the utility model, greatly alleviates the charging rate of ore pulp, has reduced the kinetic energy of ore pulp, has reached ore pulp and the organic optimum state of mixing of flocculant.
In the utility model reinforced well indoor design be about two helical layer feeding-passages, the hand of spiral is opposite, the section at certain inclination angle is arranged in the helical duct, the mixture 1 of ore pulp and medicament is cut 2,2 to be cut 4,4 and cuts 8 the cutting of dividing equally, the long strand of medicament is played one's part to the full, catch to greatest extent the fine particle thing in the ore pulp.
The utility model has the advantages that:
The utility model is scientific and reasonable for structure, is provided with isocon and enters in the feed pipe, reduces the charging rate of ore pulp, can at utmost bring into play the effect of flocculant, has improved flocculation efficiency, has reduced cost.
