Grinding device

Abstract

The invention discloses a grinding device mainly used as a grinding dispersion machine or a colloid mill. The grinding device is simple in structure, low in cost, convenient to machine and install, good in heat dissipation, suitable for high rotating speed and the like. The grinding device comprises a main shaft, three stages of static grinding bodies, a top cover, four stages of movable grinding bodies, a shell, an adjusting disk, a handle, a lock nut, a cooling liquid pipe inlet connector, a cooling liquid pipe outlet connector and the like. The movable grinding bodies are provided with four stages of sawtooth protrusions and grooves, the four stages of sawtooth protrusions and grooves become thin from thick, the fourth stage adopts a metal coating, and the distance between the three stages of static grinding bodies and the four stages of movable grinding bodies and the distance between the top cover and the four stages of movable grinding bodies can be adjusted; by means of a fineness-degree-increased grinding head rotating at a high speed, finally, micro-nano-level material particles are obtained; the four stages of movable grinding bodies are fixed to the main shaft and locked through the lock nut at the front end of the main shaft; the adjusting disk is arranged above the shell, the handle is installed on the adjusting disk, and the handle adjusts the adjusting disk so that the processing precision of materials in a cavity can be increased; and the top cover is arranged on the adjusting disk, the top cover is provided with the cooling liquid pipe inlet connector and the cooling liquid pipe outlet connector, the cooling liquid pipe inlet connector is connected with an annular cooling liquid channel, cooling liquid is added at any time, the adjusting disk, the materials and a grinding disk are protected, and the situation that the using performance is affected by the too-high temperature is avoided.

Description

technical field [0001] The invention mainly relates to the technical fields of medicine, biology, chemical industry and beverage emulsion, in particular to a grinding and dispersing machine and a colloid mill. Background technique [0002] At present, biological, pharmaceutical, chemical, beverage and other enterprises urgently need a device with high fineness, but the grinding of existing equipment cannot meet the needs of users; the existing grinding devices are all three-stage grinding, and the ground powder particles It is still relatively large, and the heat dissipation conditions of the existing equipment are poor, so that the chemical reaction of the chemical solution due to the temperature rise cannot meet the requirements. After a period of grinding, the rotor wears a lot, and the rotor needs to be replaced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method to reduce energy consumption, improve th...

[0002] At present, biological, pharmaceutical, chemical, beverage and other enterprises urgently need a device with high fineness, but the grinding of existing equipment cannot meet the needs of users; the existing grinding devices are all three-stage grinding, and the ground powder particles It is still relatively large, and the heat dissipation conditions of the existing equipment are poor, so that the chemical reaction of the chemical solution due to the increase in temperature cannot meet the requirements. After a period of grinding, the rotor wears a lot, and the rotor needs to be replaced.
