Low energy consumption lifting mixing bucket

Abstract

The invention discloses a low-energy-consumption lifting mixing barrel. A mixing shaft is inserted into a barrel body, a motor and a reducer drive the mixing shaft to rotate, the mixing shaft is sequentially provided with a lower suspension spraying mixer and a bottom sweeping mixer from top to bottom, wherein the lower suspension spraying mixer is limited by an upper positioning step and a lower positioning step and can float up and down; the lower suspension spraying mixer comprises a mixing shaft, a shaft sleeve and a paddle, wherein the mixing shaft is a spline shaft, the shaft sleeve is also a spline shaft sleeve, the spline shaft sleeve can move on the spline shaft, and the paddle is welded on the spline shaft sleeve; the bottom sweeping mixer comprises a mixing shaft and an outer barrel, the mixing shaft and the outer barrel are welded into a whole by virtue of a paddle, the mixing shaft extends downward and forms a hollow cylinder, then the hollow cylinder extends to form a cone, and the outer wall of the cylinder is communicated with a jet pipe; and a blade tilt is gradually increased from top to bottom. The low-energy-consumption lifting mixing barrel has the characteristics that energy consumption is low, material circulation is good, deposition at the bottom is hardly caused, no mixing dead angle is formed, and light-load staring can be still realized even materials are sedimented due to long-time power failure, so that the low-energy-consumption lifting mixing barrel has a broad application prospect.

Description

technical field

[0001] The invention relates to a stirring device, in particular to a low energy consumption lifting mixing barrel. Background technique

[0002] Stirring is a unit operation often used in metallurgy, chemical industry, food, medicine and other industrial fields. The most important thing about stirring is good material circulation, no dead space and low energy consumption. When the viscosity of the material is very high, stirring is not easy. Now Most of the mixing tanks are developed towards large capacity, high solid-liquid ratio, and strong stirring, but there are also defects such as high power consumption for stirring, easy jamming of material sedimentation, and difficulty in eliminating dead corners of stirring.

[0003] Existing large-size mixing tanks generally use long-axis multi-layer long paddles for low-speed mixing. The power of the motor is large and the radius of the stirring paddles is long. The material is easy to sink to the bottom. High, s...
