High-efficiency muffling hammer slice crusher

Abstract

The invention discloses a high-efficiency muffling hammer slice crusher. The high-efficiency muffling hammer slice crusher comprises a base, a motor, a shaft coupler, a rotor, a crushing chamber and a feeding cabin, wherein the motor is connected with the rotor by the shaft coupler; the outlet of the feeding cabin is flexibly connected with the inlet of the crushing chamber; the crushing chamber comprises a shell, a rotor shaft, a sieve plate, a sieve pressing frame, a rotary tray, a connecting pin, hammer slices, a first steering structure and a second steering structure, wherein the shell comprises a panel, an inner plate and muffling cotton; the second steering structure comprises a base supporting plate, a supporting plate and a steering plate. According to the high-efficiency muffling hammer slice crusher disclosed by the invention, the hammer slices are distributed radially in the sieve plate so that the internal annular flow layers of the crushing chamber are effectively damaged and the resistance of material ring flow is increased, and thus qualified small particles can be removed to the surface of the sieve plate in time and are discharged from the crusher by passing through sieve holes; the sieving rate of materials is increased, and the crushing efficiency is greatly improved; by adopting the flexible connection and the muffling cotton, the high-efficiency muffling hammer slice crusher disclosed by the invention has the advantages of greatly reducing the working noise of the overall crusher and alleviating the noise pollution of the surrounding environment.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a high-efficiency sound-absorbing hammer mill. Background technique [0002] The crushing mechanism of the existing hammer mill is: the material enters the crushing chamber composed of the rotor, sieve plate, tooth plate, door and body from the entrance of the crusher, and the end of the hammer with a linear speed of 80m / s or more randomly wants to contact with it. After the low-velocity material collides violently with the high-speed hammer for the first time, it is pulled into the acceleration zone by the hammer, where the particle speed can be increased to close to the end linear velocity of the hammer in a short time, and then The hammers make a circular motion together. In the full speed zone, the material circulation layer is gradually formed, and the material is further crushed at the same time. After that, because the hammer blades hit the material to the s...

Problems solved by technology

Although the production efficiency of the pulverizer has been improved, the problem of material screening has not been fundamentally solved.

[0005] Moreover, the pulverizer in the prior art is very noisy when working, which not only brings noise troubles to the people working and living around, but also has adverse effects on the body and mind of the staff who have been in the noise environment for a long time.
