Dynamic mixer capable of adjusting shear strength and mixing degree

Abstract

The invention discloses a dynamic mixer capable of adjusting shear strength and mixing degree and relates to the field of dynamic mixers. A one-way valve is arranged at the position of an auxiliary material adding port; a discharging port is formed in the other end of a mixing shell; a stirring shaft is arranged in the mixing shell; a promoter blade and a stator blade are arranged on the stirringshaft; the promoter blade consists of a rhombic promoter blade perpendicular to a main shaft; the outer edge of the promoter blade is close to the inner wall of the stator blade; the stator blade consists of a rhombic stator blade perpendicular to the main shaft; the outer edge of the stator blade is close to the outer wall of the stirring shaft; the stator blade and the promoter blade are arranged alternately; and one end of the stirring shaft penetrates through a bearing box and is connected with a speed reducer. The problems that the existing fluid is mixed non-uniformly and the pressure drop is large are solved. The dynamic mixer is reasonable in structural design, simple to operate, convenient to use and easy to clean, reduces pressure, and can adjust shear strength and mixing degree.

Description

technical field [0001] The invention relates to a dynamic mixer with adjustable shear strength and mixing degree, belonging to the technical field of dynamic mixers. Background technique [0002] The materials used in the molding process of polymer materials are usually composed of different polymers, fillers, additives, etc., so mixing is a necessary stage in the molding process of polymer materials. Mixing of polymer materials is usually done by compounding the components in a continuous mixing device or a batch mixing device. At present, most of the mixers used in industry are single-type mixers, and most of them are specially used in petrochemical, oil, mining and metallurgy industries. If this type of mixer is used in the viscose industry, low-viscosity mixers should be selected. The flow time is short and the pressure drop is small, but the mixing times are not up to the requirement and the mixing is uneven. Use a high-stick mixer. The viscose mixing times are more, b...

AI Technical Summary

Problems solved by technology

At present, most of the mixers used in industry are single-type mixers, and most of them are specially used in petrochemical, oil, mining and metallurgy industries. If this type of mixer is used in the viscose industry, low-viscosity mixers should be selected. The flow time is short and the pressure drop is small, but the mixing times are not up to the requirement and the mixing is uneven. Use a high-stick mixer. The viscose mixing times are more, but the pressure drop is large, the degree of maturity changes greatly, and the quality of the finished product is affected. Influence, besides, viscose viscosity changes greatly, so it is not suitable for use

[0003] At present, static mixers are generally used to mix different fluids, and the mixing unit fixed in the tube is used to change the flow state of the fluid in the tube to achieve good dispersion and full mixing of different fluids. The mixer needs a relatively large volume, so that the pressure drop becomes larger, and the static mixer only changes the flow state of the fluid itself in the tube, the mixing effect is poor, it cannot be disassembled, and it is not easy to clean
