A circulating material lifting and screening type coal crushing device

Abstract

The invention discloses a circular material lifting screening type coal crushing device. The circular material lifting screening type coal crushing device comprises a round bottom supporting installing barrel. A concave-surface transmission installing plate is horizontally arranged on the lower half section of the inner side of the round bottom supporting installing barrel. A main transmission rotary shaft is arranged in the middle of the concave-surface transmission installing plate in a vertical penetrating mode. Synchronous driving motors are symmetrically and vertically arranged at the lower end of the concave-surface transmission installing plate in a semi-embedded mode. The lower end of the main transmission rotary shaft extends out of the concave-surface transmission installing plate and is horizontally and coaxially provided with an operation gear. The left end and the right end of the operation gear are matched with the synchronous driving motors and provided with synchronousdriving gears through motor rotary shafts in an engaged mode. The upper end of the round bottom supporting installing barrel is coaxially provided with a conical surface supporting transmission plate.A screening crushing installing barrel is arranged at the upper end of the conical surface supporting transmission plate. The circular material lifting screening type coal crushing device has the advantages of being compact in structure design, stable in transmission process, reasonable in circulation process design, high in crushing efficiency, good in crushing quality and the like.

Description

technical field [0001] The invention relates to a coal crushing device, in particular to a coal crushing device of a circulating lifting and screening type coal crushing device. Background technique [0002] Coal crushing equipment is a kind of mechanical equipment that crushes large particles of coal into small particles at various levels according to the requirements of use. It is mainly used in coal, chemical, power plant and other related industries. The currently used coal crushing device adopts a one-way crushing structure and a single The high-speed broken structure causes various problems in actual use. [0003] In order to solve the above problems, the present invention is proposed to overcome the current coal crushing device. Due to the one-way crushing structure, the crushed size is uneven, which does not meet the requirements of subsequent processing, so that the processing needs to be re-collected in the guide crushing. Time-consuming and labor-intensive, low p...

[0003] In order to solve the above problems, the present invention is proposed to overcome the current coal crushing device. Due to the one-way crushing structure, the crushed size is uneven, which does not meet the requirements of subsequent processing, so that the processing needs to be re-collected in the guide crushing. Time-consuming and labor-intensive, low processing efficiency and other problems solve the problems of the currently used coal crushing device. Due to the single high-speed crushing, the crushing elements are damaged and the crushing quality is not uniform. The present invention has a compact structure design and a stable transmission process. Reasonable circulation process design, high crushing efficiency, good crushing quality, etc.
