Description

A tank mixer for viscous materials

technical field

The utility model relates to a mixer, in particular to a tank mixer for viscous materials.

Background technique

In the field of chemical industry, many reactions with complex process changes involve the mixing of high-viscosity materials and low-viscosity materials, and the dispersion of other substances in viscous materials. Traditional large-diameter low-speed mixers (such as frame mixers, anchor mixers, ribbon mixers, barrel mixers, etc.) can only solve the general macroscopic mixing problem of viscous materials, but the dispersion is seriously insufficient. Therefore, many operations need to be stirred for a long time to achieve the purpose, and the mixing quality and efficiency are very low. However, many small-diameter high-speed agitators typically represented by turbine agitators have very good dispersion performance, but their range of action is small, and the materials retained on the wall of the cylinder cannot be fully transferred to the materials in the agitation area, resulting in Some materials are not fully mixed and dispersed all the time. Traditional mixers, when stirring viscous materials, have problems such as wall attachment, coagulation, agglomeration, and precipitation, especially wall attachment problems, because most of the stirring shafts of traditional mixers are set in the center. During the stirring process, Viscous material will stick to the wall.

Utility model content

In view of the above shortcomings, the purpose of this utility model is to provide a tank mixer for viscous materials, which can eliminate the problem of wall attachment of viscous materials while achieving uniform mixing of viscous materials.

The material guide gap, the second stirring shaft is a rod-shaped stirring shaft, which is arranged at the central position of the frame-shaped stirring shaft, and the first driving motor is arranged at the upper part of the tank body and connected with the first stirring shaft. The second driving motor is arranged on the upper part of the tank body and connected with the second stirring shaft.

Further, the upper part of the tank body is provided with a feed port, and the feed port is provided with a feed valve.

Further, the side of the tank body is provided with a limit port, and the limit port is provided with a limit valve.

Further, the inside of the frame-shaped stirring shaft is provided with a stirring baffle.

Further, stirring paddles are provided on both sides of the second stirring shaft, and the stirring paddles and the stirring baffles are misaligned.

The utility model has the following advantages: the first stirring shaft and the second stirring shaft complement each other, eliminate the mixing dead zone, can adapt to the mixing requirements of various complex processes and media, and are especially suitable for mixing and dispersing high-viscosity materials and other media . The first stirring shaft and the second stirring shaft can operate independently at two speeds, and the inner and outer paddles can be steplessly changed according to requirements, making the mixer more flexible. The first stirring shaft is a frame-shaped stirring shaft, which is compatible with the inner cavity (close to the wall of the inner cavity, with a gap of 1~10mm at most), which can prevent the viscous material from attaching to the wall, agglomeration, agglomeration, precipitation, etc. question. The central position of the bottom of the first stirring shaft is provided with a "︹"-shaped material guide gap corresponding to the discharge port, which allows the discharge operation to be performed simultaneously during the stirring process, and the most evenly mixed material at the center is discharged first.
