Description
Technical field
The present invention relates to Sha Cang field, especially relate to a kind of underground Sha Cang for stowage unit。
Background technology
Sand storehouse is widely used for concentration or the storage of mine tailing, and the last mortar of low concentration inputs from Sha Cang top, and tailings after precipitation concentration, is given off by the sandpipe of putting of bottom in sand storehouse。
Sand storehouse in correlation technique is generally built by cement and is formed or be made up of metallic plate, is then placed within ground。This traditional sand storehouse manufacturing and installation difficulty, and owing to space restriction, the finite capacity in sand storehouse, and the placement in sand storehouse can be subject to the impact of landform, when time with a varied topography, it is not easy to the construction in sand storehouse。
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 in the sand storehouse 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 sand storehouse concentration tailings, the size in sand storehouse 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) in sand storehouse, 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 in sand storehouse, 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, warehouse is high, processing and manufacturing difficulty, and cost is high, the crank in sand storehouse, installation difficulty。
Secondly, for sand storehouse, tailings concentration after concentration is the important indicator evaluating sand storehouse, present inventor also finds by studying, tailings concentration after the concentration of sand storehouse is subject to the impact of sand storehouse 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 sand storehouse 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 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, 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 in single sand storehouse 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 propose a kind of manufacture and easy for installation, capacity can increase, cost is low and is not easily susceptible to the underground Sha Cang of the influence of topography。
