Mixing barrel for coal water slurry additive

Abstract

The invention discloses a stirring barrel for a coal water slurry additive, the stirring barrel comprises a basic base, and a stirring barrel and a feeding mechanism are arranged at the upper end of the basic base. The feeding mechanism comprises a feeding box body, a grinding box body, a conveying assembly, an inclined material guide plate, a driving grinding roller, a driven grinding roller, a telescopic cylinder, an inclined vibrating mesh screen and a large inclination conveyor; a solid feeding port and a liquid feeding port are arranged at the top of the stirring barrel; a stirring shaft is vertically arranged at the middle side of the inner cavity of the stirring barrel; a rotating motor is arranges at the outer top end of the stirring barrel, an output shaft of the rotating motor is connected with the end part of the top end of the stirring shaft through a coupling, stirring rods are uniformly arranged in the stirring barrel and positioned outside the stirring shaft, a U-shaped stirring frame is arranged in the stirring barrel, a first transmission shaft is arranged at the outer top end of the stirring barrel, a second transmission shaft is arranged at the outer end of the stirring barrel, and a third transmission shaft is arranged in the middle of the bottom end of the stirring barrel.

Description

technical field [0001] The invention relates to the field of coal-water slurry additives, in particular to a mixing tank for coal-water slurry additives. Background technique [0002] CWS additives often need to be stirred during the preparation process, and the particle size of solid raw materials has a direct impact on the product; solid raw material particles may be affected by moisture during the process of preparation, transportation, and storage, and the moisture of solid raw materials may affect water coal. The production quality of slurry additives is affected; solid raw materials may adhere to the surface of conveyor belts and grinding rollers during drying, crushing and screening, which will not only cause loss of raw materials, but also reduce the cleanliness inside the equipment; mixing equipment During the stirring operation, there may be a stirring dead angle at the inner bottom corner of the mixing equipment, resulting in the accumulation of materials, and raw...

[0002] CWS additives often need to be stirred during the preparation process, and the particle size of solid raw materials has a direct impact on the product; solid raw material particles may be affected by moisture during the process of preparation, transportation, and storage, and the moisture of solid raw materials may affect water coal. The production quality of slurry additives is affected; solid raw materials may adhere to the surface of conveyor belts and grinding rollers during drying, crushing and screening, which will not only cause loss of raw materials, but also reduce the cleanliness inside the equipment; mixing equipment During the stirring operation, there may be a stirring dead angle at the inner bottom corner of the mixing equipment, resulting in the accumulation of materials, and raw materials may adhere to the inner end wall of the mixing equipment, which will cause the loss of raw materials and also affect the subsequent CWS additives. The preparation is affected; the more common stirring mode is that the motor drives the stirring shaft and the stirring rod to rotate. This kind of stirring mode has low stirring efficiency, so a new solution is needed now
