Dust-free non-bag high-efficient pulverizer

Abstract

The invention publishes a dust-free non-bag high-efficient pulverizer which comprises a motive power wheel, a material containing hopper, a discharging hopper, a pulverizing chamber and a pulverizingdevice in the pulverizing chamber and is characterized in that an air return box is additionally arranged between the material containing hopper and the pulverizing chamber, and the air return box iscommunicated with the discharging hopper through return pipes; and the size of an outlet at the outlet part of the discharging hopper is adjusted through an adjusting device. The structure of the adjusting device is that: a cover plate is hinged to the outlet of the discharging hopper through a hinge; the cover plate comprises a transverse plate and side plates at both left and right ends; the transverse plate and the side plates wrap the side faces and the top face of port parts of the discharging hopper; only an end port part is reserved; locking screws are arranged on the side plates; the cover plate is locked through the locking screws after the size of a discharging opening is adjusted; and the size of the opening of the discharge hopper is kept. Two return pipes are provided, and aresymmetrically distributed on the two sides of a feeding hopper so as to avoid influence on feeding of original crops; the bottoms of the return pipes are communicated with the inside of a cavity of the discharging hopper; and the tops of the return pipes are communicated with an air return box by through holes.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a dust-free and bag-free high-efficiency pulverizer. Background technique [0002] As everyone knows, the known jaw crusher is a processing machine for crushing grain and feed. It is mainly composed of a hopper, a crushing chamber, a sieve, and a hopper. When processing materials, the raw materials and the air enter the crushing chamber through the feed port. After the raw materials are crushed by the high-speed rotating claws in the crushing chamber, they pass through the sieve hole together with the air and enter the discharge hopper. Finally, the mixture is discharged from the discharge port. discharge. In order to prevent the dust from flying everywhere at the discharge port, when the existing claw grinder processes dry materials, it is necessary to put a section of cloth bag on the discharge port. Putting a cloth bag on the discharge port is not only inconvenient to use, but also affects th...

Problems solved by technology

However, this equipment has the following defects: 1. The design of the return air channel is narrow, which cannot effectively reduce the air pressure in the discharge hopper; 2. The return air pipe is not symmetrically arranged, resulting in disordered air flow during return air and poor circulation; 3. The discharge port The design is also unreasonable and cannot effectively block the air, resulting in poor circulation

Therefore, the product still has relatively large dust when in use
