Sided-intake sealer of agitator

Abstract

The invention is concerned with the sealing equipment for the side moving beater, it is: fixes inside end surface machine seal that crosses the inside wall of the container, fixes outside end surface machine seal between the beating axis and the outside wall of the container. The outside end surface machine seal is double end surface machine seal that fixes on the beating axis by the sealing fixing bushing. The invention is small fraying consumption, better sealing efficiency.

Description

technical field [0001] The present invention relates to an agitator for uniform mixing of liquid and liquid, liquid and gas or liquid and solid powder in capacity (such as reaction tank, tank or reaction kettle, etc.), especially relates to the improvement of the sealing device of the agitator. Background technique: [0002] In petrochemical, pharmaceutical, food processing, water treatment and other industries, as well as in the production process of papermaking, titanium dioxide, thermal power plant flotation, crystallization, and flue gas desulfurization, it is often necessary to open or close the reaction tank, tank or reactor. The mixing and stirring of liquid and liquid, gas or solid powder is carried out in the container. The traditional agitator is composed of a stirring shaft and a stirring blade fixed at the end of the stirring shaft. The agitator extends the stirring blade from the top of the reaction vessel below the liquid surface to stir and mix the materials. ...

Problems solved by technology

Therefore, on the one hand, this kind of sealing device has the fast wear of the packing, but it cannot effectively compensate the worn packing. It can only frequently tighten the packing gland bolts or replace the packing, which not only causes a large loss of stirring wear power, but also affects the working efficiency of the agitator. , which also brings great inconvenience to use and maintenance; on the other hand, the sealing device has relatively strict requirements on the working conditions of the agitator, and the working vibration and eccentric rotation of the agitator shaft will form regular or Irregular working gaps aggravate the leakage of mixing materials, which cannot achieve a stable and ideal sealing effect, and even lead to failure to work normally

At the same time, the sealing structure has relatively strict restrictions on the working pressure and stirring speed. It can neither withstand the high pressure in the closed container, nor can it withstand the positive and negative working pressure in the container at the same time. The scope of application is directly affected.

[0004] Therefore, the existing agitator sealing device not only has the disadvantages of severe wear of the agitator shaft, large wear power loss, and short working life of the agitator, but more importantly, there are unsatisfactory sealing effects, high requirements for the working environment, and easy This will result in the leakage of mixing materials, which not only wastes mixing materials, but also seriously pollutes the environment.
