Cyclic stirring system for solid-liquid mixed mediums in storage tank

Abstract

The invention discloses a cyclic stirring system for solid-liquid mixed mediums in a storage tank. The cyclic stirring system comprises a medium storage tank, wherein a circulating liquid pump inlet pipeline is arranged at the lower end of the medium storage tank; an outlet of a circulating liquid pump is connected with a cyclic stirring device; the cyclic stirring device enters the storage tank from three paths; two stirring spray heads are respectively arranged at the tail end of each of three cyclic stirring pipelines; the six stirring spray heads are respectively positioned on three different levels on two concentric circumferences; the mediums obtain high-enough dynamic energy after being pressurized by the circulating liquid pump and are sprayed out through the six spray heads; circulating liquid sprayed out of the spray heads form tangent angles together with the two concentric circles of the circumference of the storage tank, so that the mediums in the storage tank can obtain high rotation stirring power, and the liquid can rotate in the storage tank. The cyclic stirring system disclosed by the invention can effectively stir the mediums in the storage tank, so that the phenomenon that solid components are deposited at the bottom of the tank due to staying of the mixed mediums is prevented, reduction of the effective volume of the storage tank is avoided, and successful production is guaranteed.

Description

technical field [0001] The invention relates to a solid-liquid mixed medium circulation stirring system in a storage tank of a coking enterprise, specifically a medium circulation stirring system. Background technique [0002] In the prior art, in order to prevent solid-liquid separation of the solid-liquid mixed medium in the storage tank for a long period of time, the solid part will be deposited at the bottom of the tank to reduce the effective volume of the storage tank and affect the smooth production. Entry or side entry agitators. The blades of the agitator protruding into the medium rotate to make the medium run in a certain order in the storage tank, preventing the medium from standing still for a long time and causing solid-liquid separation. [0003] Whether it is a top-entry agitator or a side-entry agitator, the blades of the agitator only intervene in a certain position in the storage tank, that is, the medium agitation effect generated by the rotation of the ...

Problems solved by technology

In other words, the agitator can only make a part of the medium or a small amount of the medium achieve stirring motion, and can only prevent part or a small amount of the medium from being separated when it is still, while the other part of the medium will still have enough time for solid-liquid separation to occur.

[0004] In addition, if the top-entry or side-entry agitator is used in a highly corrosive medium, the maintenance of the agitator will be very frequent

If the agitator is to be repaired, it is necessary to empty the medium storage tank and stop production, which will affect the production
