Problems solved by technology

The two kinds of external air ducts need to return air from the height of the material inlet, resulting in a large extension of the return air passage, and there is an elbow greater than 90°, which greatly increases the return air resistance and reduces the balance effect. Limited improvement in exhaust air volume

Abstract

The invention relates to the field of mine crushing equipment, and specifically relates to an internal air flow self-circulation type impact crusher. A feeding port slide carriage is arranged below a feeding port of a machine frame, a front side plate is arranged below the feeding port slide carriage, the front side plate is fixedly connected with the machine frame, the front side plate is bent, and a feeding port baffle is arranged on the portion, between the front side plate and a rotor, of the machine frame. A gap is formed between the feeding port baffle and the rotor, an air channel is formed among the feeding port baffle, the front side plate and the machine frame for fixing the front side plate, the gap between the tail end of the feeding port baffle and the tail end of the front side plate is an air inlet, and the gap between the top end of the feeding port baffle and the top end of the front side plate is an air outlet. By means of the air channel, air flow generated when the rotor runs is subjected to internal self-circulation with the shortest distance and the minimum resistance, the air return distance is almost zero, the air return efficiency is improved, the air pressure at the position of a discharging port is reduced, it is ensured that the total exhaust air amount in the impact crusher is close to zero, the exhaust air amount is decreased, and the dust removal power is reduced.

Description

Technical field [0001] The present invention relates to the field of mine crushing equipment, and more particularly to an internal gas stream from a cyclic crusher. Background technique [0002] As a crusher for crushing materials using impact principles, it has the characteristics of simple structure, high reliability, good product granules, and wide range of applications. It is widely used in mining, chemical, construction, railway and other industries. [0003] In the process of high-speed operation, the anti-crusher rotor will produce a large amount of fine powder. At the same time, the high-speed operation of the rotor also generates a fan effect, causing a large gas flow inside the crusher, such as a 200kW power anti-crusher, can generate 10,000 cubic meters of dust-containing gas per hour. [0004] In order to improve the crushing efficiency, avoid the material directly from the feed opening without participating in the collision, the inlet baffle of the general counteratt...
