Rotor and vertical shaft type impact crusher provided with rotor

Abstract

The invention discloses a rotor and a vertical shaft type impact crusher provided with the rotor. The rotor comprises a paraboloidal head which is fixedly arranged on a vertical rotor wall, wherein the paraboloidal head at least consists of two or more sections of sectioning bodies of a separating body; and each sectioning body is consistent in structure. The body of each sectioning body is connected with the vertical rotor wall into a whole through a connecting arm which is extended out from the body; a lapping bent arm also extends out from the body; the lapping bent arm and the side wall of the vertical rotor wall associated with the lapping bent arm form a closing cavity; and a balance block is arranged in the closing cavity. After the separable paraboloidal head structure with the balance block is adopted, once the sectioning body in an abrasion area is worn out by a material and the connecting arm is broken, the balance block flies away from a rotor with the sectioning body, equipment is unbalanced seriously, a strong and reliable vibration signal is provided to a vibration detecting device, and the vibration detecting device is enabled to be timely started and stopped in a reinforcing way. When necessary, the paraboloidal head is replaced by only replacing the sectioning body which is seriously damaged according to condition without overall replacement.

Description

【Technical field】 [0001] The invention belongs to a rotor and a vertical shaft impact crusher equipped with the rotor. 【technical background】 [0002] In a vertical shaft impact crusher, the rotor typically has a horizontal upper and lower plate connected by a vertical rotor wall. The upper disc has holes for feeding material into the rotor. Material is deposited on the lower pan and is thrown from the parabolic head of the rotor through openings in the vertical rotor wall. The parabolic head is mounted on the discharge side of the vertical rotor wall and is embedded with a hard material, such as hard metal, to protect the vertical rotor wall from wear caused by material exiting the rotor at high speed. In practice, since the parabolic head is a wearing part, the replacement cycle is generally 2-7 days. When the throwing head is worn out, it needs to be shut down for maintenance in time to avoid the phenomenon of endangering the vertical rotor wall and causing heavy losse...

AI Technical Summary

Problems solved by technology

However, the existing equipment has the following problems: when the detection device detects the vibration of the equipment and forces the machine to stop, the vertical rotor wall is often severely worn

This method is time-consuming and labor-intensive, and the effect is poor, resulting in frequent replacement of the vertical rotor wall due to wear and tear; moreover, due to changes in the hardness, size, speed and other factors of the material, the wear area suffered by the throwing head It is also different. The current situation is: no matter which area of ​​the throwing head is worn out, the entire throwing head has to be replaced. Since hard metals are very expensive, the production cost of the enterprise has been greatly increased.
