Side inserted agitator

Abstract

The invention relates to an agitator, in particular to a side inserted agitator, is mainly used for blending products in storage tanks and / or preventing precipitation in petroleum refining enterprises, chemical enterprises, storage and transportation companies and the like, and belongs to the technical field of agitation machinery. The agitator comprises a bracket (1), a motor (2), a reduction gearbox (3), a spindle (5) and an impeller (8), wherein the bracket (1) comprises a vertical plate (1.1) and a transverse plate (1.2); the motor (2) is fixedly arranged on the transverse plate (1.2); anouter extending bearing (6) and a shaft sleeve (9) are sleeved on the spindle (5); one end of an outer extending bearing (7) is connected with the vertical plate (1.1); a mechanical seal (10) is fixedly sleeved on the shaft sleeve (9); and a fixed flange (11) is arranged outside the mechanical seal (10). The side inserted agitator has the advantage that the mechanical seal is hardly damaged, and can be applied to agitating asphalt, paraffin and other colloidal materials.

Description

technical field [0001] The invention relates to a stirrer, in particular to a laterally extending stirrer, which is mainly used for blending or preventing precipitation of products in storage tanks of petroleum refining enterprises, chemical enterprises, storage and transportation companies, etc., and belongs to stirring machinery technology field. Background technique [0002] In the storage tanks of petroleum refining companies, chemical companies, storage and transportation companies, etc., it is often necessary to use agitators to stir and reconcile the products in the storage tanks, so as to prevent the products in the storage tanks from delamination and precipitation, which will affect product quality. . However, when the commonly used lateral extension type agitator is stirring colloidal materials such as asphalt or paraffin, part of the asphalt or paraffin in the high-temperature molten state in the tank will inevitably leak out along the main shaft.

AI Technical Summary

Problems solved by technology

However, when the commonly used lateral extension type agitator is stirring colloidal materials such as asphalt or paraffin, part of the asphalt or paraffin in the high-temperature molten state in the tank will inevitably leak out along the main shaft. The temperature is low, the leaked asphalt or paraffin is easy to solidify the main shaft and the mechanical seal after cooling, and the mechanical seal is easy to be damaged if the agitator continues to work.
