Thick slurry stirring chemical combination bucket

Abstract

The invention discloses a thick slurry stirring chemical combination bucket. The thick slurry stirring chemical combination bucket comprises a bucket body, a motor, a speed reducer and a stirring shaft, wherein the stirring shaft is inserted in the bucket body; the motor and the speed reducer drive the stirring shaft to rotate; the stirring shaft is sequentially provided with a bottom sweeping stirrer, a multi-stage series lower jet stirrer, a bidirectional jet stirrer and a suspension lower jet stirrer from bottom to top; the suspension lower jet stirrer is limited by upper and lower location steps, and capable of floating up and down. The thick slurry stirring chemical combination bucket disclosed by the invention has the characteristics of being low in energy consumption, great in material circulation, not liable to sink to the bottom, and capable of being started by a light load even if material sedimentation is caused by long-time power failure, as well as has a wide application prospect.

Description

technical field [0001] The invention relates to a compounding device, in particular to a thick slurry stirring compounding barrel. Background technique [0002] Compounding is a unit operation often used in metallurgy, chemical industry and other fields. The most important thing in the compounding process is to fully mix the reactants during the compounding process without leaving any dead space. Therefore, the existing compound barrels are generally equipped with a stirring device, and the reactants are fully mixed by stirring, so as to obtain a better compound effect. When the viscosity of the reactants is very high, it is difficult to stir, so the current compound tanks are all developing towards large capacity, high solid-liquid ratio, and strong stirring, but there are also problems such as high power consumption for stirring, and easy jamming of materials due to sedimentation. , It is difficult to eliminate the defect of stirring dead angle. [0003] The existing lar...

Problems solved by technology

When the viscosity of the reactants is very high, it is difficult to stir, so the current compound tanks are all developing towards large capacity, high solid-liquid ratio, and strong stirring, but there are also problems such as high power consumption for stirring, and easy jamming of materials due to sedimentation. , It is difficult to eliminate the defect of stirring dead angle

[0003] The existing large-scale mixing tank has a diameter of 9 meters and a liquid pool depth of 9 meters. Generally, long-axis multi-layer long paddles are used for low-speed stirring. The motor configuration is 55-75KW, and the stirring shaft rotates at about 1 rpm. The radius of the paddle is 2.5 meters, the mineral powder is easy to sink to the bottom, the material will be stuck when the power is off, and the stirring will even fail to start, and the power consumption is very high. Therefore, the existing stirring device cannot meet the technical requirements of high viscosity and large size compounding barrel
