Description

A double stirring tank

technical field

The utility model relates to a stirring device, in particular to a double-stirring type stirring tank.

Background technique

Stirred tanks are widely used in the chemical industry. For example, in the production of catalysts, stirred tanks are one of the core equipment. Because catalysts such as cracking catalysts are inorganic powdery granular products, and are mainly used in refining catalytic cracking units. The product has a large amount of use and high technical content, and has strict requirements on various technical indicators such as physical chemistry. Therefore, the production process of the catalyst is complicated, and the performance requirements for the production equipment are relatively high. In the process of using stirred tanks to produce catalysts, gelation reactions are often involved. The basic materials are liquid phases, and the added materials are solid phases. Form requirements are high. At this stage, the various stirred tanks in the industry mainly use a stirring shaft with a stirring paddle for stirring. Stirring dead zones and wall sticking phenomena appear during the gelation process, which will reduce the efficiency and effect of catalyst production. Therefore, it is of positive significance to provide a stirred tank that can effectively avoid the phenomenon of stirring dead zone and wall sticking during the reaction.

Utility model content

The purpose of this utility model is to provide a double-stirred stirring tank, which adopts a double-shaft stirring method, can rotate in the same direction or reversely, can effectively avoid the phenomenon of stirring dead zone and wall sticking in the reaction, and improve the reaction efficiency and effect.

The technical scheme of the utility model is as follows:

A double-stirring stirring tank, including a cylinder, a main coupling and a main deceleration motor are installed on the upper end of the cylinder, supports are distributed on the outer wall of the upper part of the cylinder, and the shaft of the main deceleration motor is connected to the main agitator through the main coupling. Shaft, the main blade is installed on the lower part of the main stirring shaft, and the main blade includes a U-shaped blade, and an oblique connecting rod is connected between the middle part of the U-shaped blade and the main stirring shaft; The rotating shaft of the auxiliary reduction motor is connected with the auxiliary stirring shaft through the auxiliary coupling, and the auxiliary blade is installed on the lower part of the auxiliary stirring shaft.

The cylinder wall of the cylinder has a cavity, and an electric heating rod is arranged in the cavity.

The U-shaped structure of the main blade of the stirring tank of the utility model can not only stir the material in the stirring tank but also vibrate, adopt the biaxial stirring method, and can rotate in the same direction or in the opposite direction, which can effectively avoid stirring dead in the reaction. Area and wall sticking phenomenon, improve reaction efficiency and effect.
