Shot blasting structure

Abstract

The invention belongs to the field of shot blasting devices, and particularly relates to a shot blasting structure. According to the scheme, the shot blasting structure is mainly characterized in thata partition plate which partitions a tank body into a screening cavity and a shot outlet cavity is arranged in the tank body; a vibration mechanism for vibrating steel shots up and down is arranged in the screening cavity; a rotary blade is arranged on the upper portion of the partition plate; the blade is inclined downwards in the rotation direction; the screening cavity is located in the rotation speed of the blade; a sliding plate is slidably connected with the inner wall of the shot outlet cavity; the steel shots can collide with the sliding plate after colliding with the rotary blade; asliding rack is fixedly connected with the sliding plate; a winding gear is engaged with the sliding rack; a winding shaft is connected with the winding gear coaxially, unidirectionally and rotationally; a reset spring is arranged between the sliding plate and the tank body; wet cloth is wound on the winding shaft; a plurality of air outlets are formed in the tank body; the air outlets are locatedover the blade; and the wet cloth is located above the air outlets. The steel shots collide mutually through vibration, and thus rust stains on the surfaces of the steel shots are removed and prevented from contaminating the steel shots again.

Description

technical field [0001] The invention belongs to the field of shot blasting devices. Background technique [0002] Shot blasting refers to throwing the pellets onto the working surface at a high speed and a certain angle by a mechanical method, allowing the pellets to impact the working surface, and then cleaning the pellets and The cleaned-up impurities are recovered separately and the pellets can be reused. Compared with other surface treatment technologies, it is faster and more effective. At the same time, the shot blasting machine is used with a dust collector, and the smoke and dust and attachments generated during the work process are recycled and treated in a unified manner, which is more environmentally friendly. [0003] According to the structure of the casting carrier, the shot blasting machine is divided into drum type, chain plate type, rotary table type, trolley type, squirrel cage type and hanging type shot blasting machine. Drum and chain plate shot blastin...

AI Technical Summary

Problems solved by technology

[0004] When the shot blasting machine is used to derust the plate, after hitting the plate, the surface of the steel shot is adhered to rust, and the rust is closely attached to the steel shot due to the strong impact between the steel shot and the plate, which is not easy to remove

Therefore, when the steel shot with rust attached to it collides with the plate again, the rust on the steel shot will adhere to the plate again, reducing the effect of removing rust.
