High-efficiency universal pulverizer with dispersed feeding function

Abstract

The invention provides a high-efficiency universal pulverizer with a dispersed feeding function. The high-efficiency universal pulverizer comprises a pulverizer body with a pulverizing chamber and a powder collecting chamber, a feeding hopper mounted on the pulverizer body and used for feeding materials into the pulverizing chamber, a pulverizing assembly mounted in the pulverizing chamber, and adriving mechanism used for driving the pulverizing assembly to perform pulverizing action, wherein the pulverizing assembly comprises a gear ring coaxial with the pulverizing chamber, a rotary drum located on the inner side of the gear ring and coaxial with the gear ring, and a plurality of crushing hammers located between the gear ring and the rotary drum, and the crushing hammers are annularly distributed in the circumferential direction of the rotary drum and fixedly assembled with the rotary drum; and a feeding port communicating with the discharging end of the feeding hopper is formed inone end of the rotary drum, and a notch is formed in the circumferential face of the rotary drum and located between any two adjacent crushing hammers. The wear rate of each crushing hammer is greatlybalanced, the service life of each crushing hammer is prolonged, and the problem of uneven stress of a transmission shaft caused by unbalanced wear of each crushing hammer and the problem of shakingof the pulverizer can be avoided.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a high-efficiency universal pulverizer for dispersing and feeding materials. Background technique [0002] The universal pulverizer is suitable for pharmaceutical, chemical, metallurgy, food, construction and other industries. It can process hard and difficult materials, including crushing plastic, copper wire, Chinese herbal medicine, rubber, etc. It can also be used as supporting equipment for the pre-processing process of micro pulverizers and ultrafine pulverizers. In the existing universal pulverizer, due to the unbalanced contact between the internal crushing parts (such as the crushing hammer) and the materials that first enter the crushing chamber, the wear rate of the crushing parts is also different (the first contact with the material crushing part The amount of wear will be greater than the wear amount of the secondary contact crushing components), which will cau...

AI Technical Summary

Problems solved by technology

In the existing universal pulverizer, due to the unbalanced contact between the internal crushing parts (such as the crushing hammer) and the materials that first enter the crushing chamber, the wear rate of the crushing parts is also different (the first contact with the material crushing part The amount of wear will be greater than the wear amount of the secondary contact crushing components), which will cause different degrees of wear and uneven quality of the crushing parts. When the crushing quality is uneven, the balance between the crushing parts will be broken. Once the balance is damaged If the crusher continues to work, it will not only affect its crushing efficiency, but also shorten the service life of its internal components
