Description
Technical field
This utility model relates to Sha Cang field, especially relates to a kind of sand storehouse.
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；Concentrator and deep wimble thickener have an advantage of working stability, but concentrator
There is discharge concentration to be 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.
Utility model content
The application is to make following facts and the discovery of problem and understanding based on inventor:
The warehouse in the sand storehouse in correlation technique is made up of two parts: superposed cylindrical portion and the circular cone being positioned at cylindrical portion lower end
Portion or truncated cone portion (also commonly referred to as boring at the end), the internal diameter of the upper end (end greatly) of conus portion is identical with the internal diameter of cylindrical portion, circle
The external diameter of the upper end in tapering is identical with the external diameter of cylindrical portion, and cylindrical portion and conus portion are generally integrally formed.
Sand storehouse to be improved concentrates the disposal ability of tailings it is necessary to increase the size in sand storehouse, and such as, the height H in sand storehouse is (i.e. from circle
The upper end in post portion is to the size of the lower end of conus portion), the height H1 of conus portion, the height H2 of cylindrical portion and cylindrical portion interior
Footpath D needs to expand.But, present inventor is found by research, although the size expanding warehouse can improve sand storehouse
Disposal ability, the concentration pulping weak effect in sand storehouse, 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, and warehouse is high, processing and manufacturing difficulty, and cost is high, the crank in sand storehouse, installation difficulty.
Secondly, for sand storehouse, the tailings concentration after concentration is the important indicator evaluating sand storehouse, present invention
People is also found by research, and the tailings concentration after the concentration of sand storehouse is by the ratio H/D of sand storehouse height H Yu the internal diameter D of cylindrical portion
Impact, additionally affected by the tapering of conus portion, by substantial amounts of research and checking, be inventors herein have recognized that
When H/D is in the range of 2-5, the concentrated effect of tailings is good.
Therefore, if increase sand storehouse height H to improve disposal ability, the internal diameter D of cylindrical portion is also required to increase accordingly, but
It is that 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
Big H1, thus further increases the whole height H in sand storehouse.
And then, present inventor also studies discovery, and the height H1 of conus portion is not the dischargeable capacity in sand storehouse, if height
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 in the sand storehouse at single cone end is limited by multiple factors, deposits
In the difficulty that disposal ability improves.
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 practicality is new
Type a kind of disposal ability of proposition is high, concentrated effect is good and the sand storehouse of height reduction.
