Mechanical impact mill

Abstract

The invention relates to the technical field of bioengineering equipment, and discloses a mechanical impact mill. The mechanical impact mill comprises a fixed box, an air extractor is fixedly arranged in the center of the bottom of an inner cavity of the fixed box, an air conveying pipe is fixedly arranged on the upper surface of the air extractor, a middle separating plate is fixedly arranged in the inner cavity of the fixed box and located above the air conveying pipe, a separation net is fixedly arranged in the middle of the middle separating plate and located right above the air conveying pipe, an air return pipe is fixedly connected to the left side of the air conveying pipe, and the top end of the air return pipe fixedly communicates with the inner cavity of the fixed box. Through the arrangement of the air return pipe, air in the fixed box is pumped through the air return pipe, air flow in the fixed box is pumped, pressurized and released within a certain time, self-circulation is achieved, the situation that a lot of air flow carries materials which do not reach the fineness to be discharged is avoided, the crushing quality of the materials is improved, subsequent treatment processes are reduced, and the preparation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bioengineering equipment, in particular to a mechanical impact mill. Background technique [0002] At present, in the medium preparation process, the material needs to reach a certain fineness, so the material is crushed by a mill, in which the mechanical impact mill uses the impact elements (blades, hammers, Rods, etc.) exert a violent impact on the material, and produce a severe impact between it and the stator and between the material and the material, so as to crush with a strong force, and then the material follows the airflow and is screened in a grading equipment, but at present There are some deficiencies in the impact mill, as follows: [0003] The current impact mill uses a large air volume to transport materials, driving the materials to hit the rotor, but a large amount of airflow is charged into the crushing area, and the flow of airflow out is also huge, causing some materials with larger p...

Problems solved by technology

[0003] The current impact mill uses a large air volume to transport materials, driving the materials to hit the rotor, but a large amount of airflow is charged into the crushing area, and the flow of airflow out is also huge, causing some materials with larger particle sizes to flow out with the airflow, resulting in the discharge of The particle size of the material is too large, the fineness range is large, and the quality is different. It needs to be screened in the later stage. Similarly, a large amount of crushed material is contained in the air flow, and the air flow needs to be dedusted, which increases the processing cost.
