Discharging and screening device of shot blasting machine

Abstract

The invention discloses a discharging and screening device of a shot blasting machine. The discharging and screening device of the shot blasting machine comprises a base, wherein a ventilation barrelis arranged above the base; a main shaft is arranged on the right side of the ventilation barrel, and a cleaning brush is arranged below the right side of the main shaft; an electrostatic dust removeris arranged above the right side of the cleaning brush, and a dust discharging window is arranged above the right side of the electrostatic dust remover; a feeding hole is formed in the right side ofthe dust discharging window; and a conveying belt is arranged below the feeding hole. According to the discharging and screening device, the conveying belt and the cleaning brush are arranged below the feeding hole, and therefore discharging objects can be automatically conveyed; moreover, the discharging objects are cleaned by the cleaning brush while moving, and therefore secondary cleaning iscarried out in case that the discharging objects are not cleaned up by the electrostatic dust remover; different collecting pipes are arranged below the cleaning brush, and therefore the discharging objects with different specifications can be collected; and residual stains are removed in a dirt collection pipe again, and therefore multiple times of cleaning can be realized, and the discharging objects with different specifications can be collected.

Description

technical field [0001] The invention belongs to the technical field of discharge screening devices, and in particular relates to a discharge screening device for a shot blasting machine. Background technique [0002] Shot blasting is also the name of a mechanical surface treatment process, similar processes include sandblasting and shot peening. Shot blasting is a cold treatment process, which is divided into shot blasting cleaning and shot blasting strengthening. As the name implies, shot blasting is to remove impurities such as surface oxide skin to improve the appearance quality. Shot blasting is to use high-speed moving projectile flow to continuously impact the surface of the workpiece to be strengthened. The surface and surface layer of the target are forced to undergo the following changes during the cyclic deformation process, the microstructure is modified, the non-uniform plastic deformation outer layer introduces residual compressive stress, the inner surface laye...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of shot blasting machine discharge screening device, to solve the problem that when the existing shot blasting machine discharges the material proposed in the above background technology, it is taken out from the collection box uniformly, without further classification and collection, and different The steel shots of the specifications are collected in an orderly manner, and some steel shots that fail to be processed need to be screened out during collection. However, the current screening and classification work generally requires manual operations by staff. Due to the fast discharge rate of the shot blasting machine, not only It makes the staff very hard and there are many kinds of classification specifications, which prolongs the working time and reduces the work efficiency, and the problems cannot be collected perfectly
