Description

Concentrator
Technical field
The present invention relates to concentrator field, especially relate to a kind of concentrator.
Background technology
Common Tailing thickening equipment has sand storehouse, concentrator/deep wimble thickener. Sand storehouse initially put into low, operating cost is low, but disposal ability is limited, job stability is not good enough; The advantage that concentrator and deep wimble thickener have working stability, but concentrator exists discharge, and concentration is restricted, initially put into height, the shortcomings such as operating cost is high, and after equipment disposal ability and specification increase, harrow frame fabrication and installation difficulty increases, and stability declines, and also can improve installation and operation cost further.
Summary of the invention
The application is based on inventor to the discovery of following facts and problem and what understanding was made:
The warehouse of the concentrator in correlation technique is made up of two parts: superposed cylindrical portion and the conus portion or truncated cone portion (being also commonly referred to as the cone end) that are positioned at cylindrical portion lower end, the internal diameter of the upper end (greatly end) of conus portion is identical with the internal diameter of cylindrical portion, the external diameter of the upper end of conus portion is identical with the external diameter of cylindrical portion, and cylindrical portion and conus portion are generally integrally formed.
Improve the disposal ability of concentrator concentration tailings, the size of concentrator will be increased, such as, the height H (namely from the upper end of cylindrical portion to the size of the lower end of conus portion) of warehouse, conus portion height H1, the height H2 of cylindrical portion and the internal diameter D of cylindrical portion need expand. But, present inventor finds by studying, although the size expanding warehouse can improve the disposal ability of concentrator, the concentration pulping weak effect of concentrator, the concentration of the tailings after concentration is difficult to control to, and affects follow-up filling effect, and, the height H of warehouse increases, warehouse is high, processing and manufacturing difficulty, and cost is high, the crank of concentrator, installation difficulty.
Secondly, for concentrator, tailings concentration after concentration is the important indicator evaluating concentrator, present inventor also finds by studying, tailings concentration after concentrator concentration is subject to the impact of concentrator height H and the ratio H/D of the internal diameter D of cylindrical portion, is additionally subject to the impact of the tapering of conus portion, by substantial amounts of research and checking, inventors herein have recognized that when H/D is in the scope of 2-5, the concentrated effect of tailings is good.
Therefore, if increase concentrator height H to improve disposal ability, the internal diameter D of cylindrical portion is also required to corresponding increase, but, if the height H1 of conus portion is constant, the tapering of conus portion becomes big, affects blanking and concentrated effect, thereby have to increase H1, thus further increase the whole height H of concentrator.
And then, present inventor also studies discovery, and the height H1 of conus portion is not the dischargeable capacity of concentrator, if height H1 is too big, it is unstable that tailings enters the concentration after conus portion, and then affects concentrated effect.
Therefore, inventors herein have recognized that, the disposal ability of single concentrator boring the end improves the restriction being subject to multiple factor, there is the difficulty that disposal ability improves.
It is contemplated that one of technical problem solved at least to a certain extent in correlation technique. For this, the present invention proposes that a kind of disposal ability is high, concentrated effect is good and the concentrator of height reduction.

Preferably, cylindrical portion 10 and the height sum of conus portion 11 are 2-5 with the ratio of the internal diameter of cylindrical portion 10. In other words, the internal diameter of cylindrical portion 10 is D, and the height of each conus portion 11 is H1, and the height of cylindrical portion 10 is H2, and the height sum of N number of conus portion 11 is NH1, and (H2+NH1)/D is 2-5, N >=2. Such that it is able to improve the concentrated effect of tailings.
In some embodiments of the invention, the outside wall surface of conus portion 11 is provided with for the nozzle (not shown go out) of jet fluid in the inner chamber to conus portion 11. Thereby through being provided with nozzle, it is possible to jet fluid (such as water or gas) in conus portion 11, it is to avoid last mortar lumps and blocks and put sand mouth 12, can control to put sand concentration and flow simultaneously, and then the reliability of concentrator 100 can be improved. Further, as it is shown in figure 1, the sand mouth 12 of putting of each conus portion 11 is respectively connected with and puts sand branched pipe 3, at least two conus portion 11 put sand branched pipe 3 all with put sand house steward 4 and be connected. So that the simple in construction of concentrator 100.
Concentrator 100 according to the specific embodiment of the invention is described in detail below with reference to Fig. 3 and Fig. 4.
As shown in Figure 3 and Figure 4, concentrator 100 includes warehouse 1 and five harrow frames 2, warehouse 1 includes cylindrical portion 10 and six conus portions 11, the upper end of each conus portion 11 is all connected with the lower end of cylindrical portion 10, the inner chamber of each conus portion 11 and the inner space of cylindrical portion 10, the lower end of each conus portion 11 has puts sand mouth 12. It is understood that the top of cylindrical portion 10 can be provided with feeding cylinder (not shown go out), after tailings is delivered to feeding cylinder, by the dilution of feeding cylinder with add flocculant, tailings is made more uniform to be distributed in warehouse 1. It is alternatively possible to the diameter of feeding cylinder is set to 6m, thus 1000��1500m can be handled up to per hour3Tailing slurry.
Five harrow frames 2 are respectively correspondingly located in five conus portions 11 to stir the material in five conus portions 11.
As shown in Figure 3 and Figure 4, six conus portions 11 include a center circle tapering 11a and five periphery conus portion 11b, the central longitudinal axis of center circle tapering 11a overlaps with the central longitudinal axis of cylindrical portion 10, and the upper surface of five periphery conus portion 11b is centrally located on the same circumference centered by the center of the upper surface of center circle tapering 11a.That is, five periphery conus portion 11b are arranged in annular, the upper surface of five periphery conus portion 11b is in the same plane, and the upper surface of five periphery conus portion 11b is centrally located on same circumference, above-mentioned circumference is with the center of the upper surface of center circle tapering 11a for the center of circle, and the center of the upper surface of center circle tapering 11a and cylindrical portion 10 are centrally located on same vertical curve.
Of course, it should be understood that the number of conus portion 11 is not limited to this, conus portion 11 can be set according to the actual treatment demand of concentrator 100, for instance conus portion 11 can also be two, three, four or more than five.
As it is shown on figure 3, periphery conus portion 11b is uniformly distributed along the circumference of cylindrical portion 10. So that the last mortar in cylindrical portion 10 is evenly distributed in the conus portion 11b of periphery, it is further ensured that the concentration effect of last mortar.
As shown in Figure 4, the height of the center circle tapering 11a height less than periphery conus portion 11b. Of course, it should be understood that the height of center circle tapering 11a can also more than or equal to the height of periphery conus portion 11b.
