A magnetic drive stirring device with a silent and stable structure

Abstract

The invention discloses a magnetic drive type stirring device with a mute and stable structure, which relates to the technical field of stirring and includes a stator assembly, a rotor assembly, a discharging assembly, an outer stirring tank, an inner stirring tank and a mute assembly. The feeding port and the discharging port are arranged under the outer stirring tank. The stator assembly, the rotor assembly and the discharging assembly are arranged inside the outer mixing tank. The stator assembly and the inner wall side of the outer mixing tank are tightly connected, and the inner stirring tank is arranged inside the stator assembly. , the inner stirring tank and the stator assembly are fastened on the side away from the outer stirring tank. The invention realizes the control of the discharge position through the discharge part, which ensures that the fluid at the discharge position of the additive solution always flows rapidly, and in the present invention, the discharge position itself is also constantly moving, and the two are superimposed on each other, which can maximize the Improve the mixing effect of the additive solution and effectively reduce the work intensity of the stirring work.

Description

technical field [0001] The invention relates to the technical field of stirring, in particular to a magnetic drive type stirring device with a silent and stable structure. Background technique [0002] In chemical material production companies, stirring devices are widely used. With the continuous development of science and technology, the stirring methods have also changed, from traditional manual stirring to semi-automatic stirring, and from semi-automatic stirring to fully automatic stirring. Most of the automatic mixers are driven by the motor. The output shaft of the motor and the stirring shaft are connected to each other. This kind of stirring device needs to seal the shaft end at the joint of the shaft. Liquid leakage often occurs, and the substances stirred in the chemical field are often accompanied by toxicity, which has a great impact on the work safety of staff. In traditional chemical products stirring equipment, the addition of additives can usually only be c...

AI Technical Summary

Problems solved by technology

The vast majority of fully automatic mixers are driven by motors, and the output shaft of the motor and the stirring shaft are connected to each other. This kind of stirring device needs to seal the shaft end at the shaft connection, and the structure of the shaft end sealing part is complicated, difficult to maintain, and Leakage often occurs, and the substances stirred in the chemical industry are often toxic, which has a great impact on the work safety of the staff

In the mixing equipment of traditional chemical products, the addition of additives can usually only be concentrated in a certain area on the surface of the mixing device. This addition method is not conducive to the effective mixing of additives and base solution. Some mixing equipment will also set the stirring shaft As a liquid outlet, the additive is scattered from the stirring impeller, but when the stirring impeller rotates, it will guide the base material solution to rotate together, so the additive discharged from the stirring impeller is usually mixed in the same fluid, and the relative flow velocity on the surface of the impeller is low On the one hand, it affects the discharge speed of the additive, and on the other hand, it is not conducive to the uniform mixing of the additive and the base solution.

Moreover, the surface of the traditional stirring impeller is easy to collide with the solid additives, which intensifies the vibration of the equipment. If the blades are set in a streamlined shape, the stirring effect will be reduced, and after the solid additives no longer collide, larger particle additives need to be processed for a long time. It takes a long time to dissolve, which greatly reduces the working efficiency of the stirring device
