Description
Technical field
This utility model relates to concentrator field, especially relates to a kind of underground concentrator for stowage unit.
Background technology
Concentrator is widely used for concentration or the storage of mine tailing, and the last mortar of low concentration inputs from concentrator top, underground,
Harrow frame is stirred, and after tailings concentrates in concentrator, is given off by the sandpipe of putting of bottom.
Concentrator in correlation technique is generally poured by cement and forms or be made up of metallic plate, but places on the ground.
This traditional concentrator manufacturing and installation difficulty, and putting due to space restriction, the finite capacity of concentrator, and concentrator
Put and can be affected by landform, when time with a varied topography, be not easy to the construction of concentrator.
Utility model content
The application is to make following facts and the discovery of problem and understanding based on inventor:
The warehouse of the concentrator in correlation technique is made up of two parts: superposed cylindrical portion and be positioned at cylindrical portion lower end
Conus portion or truncated cone portion (also commonly referred to as boring at the end), the internal diameter of the upper end of conus portion (end greatly) and the internal diameter phase of cylindrical portion
With, 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.
Concentrator to be improved concentrates the disposal ability of tailings it is necessary to increase the size of concentrator, such as, the height H of warehouse
(i.e. from the size of the lower end of the upper end of cylindrical portion to conus portion), the height H1 of conus portion, the height H2 of cylindrical portion and cylinder
The internal diameter D in portion needs to expand.But, present inventor is found by research, 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
Fill out effect, and, the height H of warehouse increases, and warehouse is high, processing and manufacturing difficulty, and cost is high, and the crank of concentrator is installed
Difficulty.
Secondly, for concentrator, the tailings concentration after concentration is the important indicator evaluating concentrator, the application
Inventor also found by research, concentrator concentrate after tailings concentration by the internal diameter D of concentrator height H and cylindrical portion
The impact of ratio H/D, is additionally affected by the tapering of conus portion, by substantial amounts of research and checking, present invention
People finds when H/D is in the range of 2-5, and 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 increase accordingly
Add, but, if the height H1 of conus portion is constant, the tapering of conus portion becomes big, affects blanking and concentrated effect, thereby has 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
Highly H1 is too big, and 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 raising of the concentrator at single cone end is limited by multiple factors
, there is the difficulty that disposal ability improves in system.
One of technical problem that this utility model is intended to solve in correlation technique the most to a certain extent.To this end, this reality
With novel proposition a kind of manufacture and easy for installation, capacity can increase, low cost and to be not easily susceptible to the underground of the influence of topography dense
Machine.
