Pass-type shot blasting machine filtering device

Abstract

The invention provides a pass-type shot blasting machine filtering device. The pass-type shot blasting machine filtering device comprises a pouring-in opening. two groups of L-shaped supporting seatsare symmetrically arranged on the pouring-in opening, two groups of spraying seats are symmetrically arranged at the bottoms of the supporting seats, two sleeves are symmetrically arranged at the bottoms of the spraying seats and are aligned with a funnel, two groups of connecting blocks are symmetrically fixed on the funnel through bolts, one tension spring is installed on each connecting block,and the other ends of the tension springs are connected with the supporting seats of the pouring-in opening. A connecting seat is arranged on the funnel, so that the connecting blocks are convenient to install and replace, a T-shaped groove is formed in the funnel, a filter screen is convenient to install, a hinged clamping block is arranged on the filter screen, the filter screen can slightly swing on the clamping block, a rotating shaft is arranged on a servo motor, the servo motor drives the rotating shaft when rotating, and therefore, a arc protrusion of the rotating shaft push the filterscreen to swing, the flowing speed of steel shots is decreased, and filtering is conveniently carried out on dust of the steel shots through the filter screen.

Description

technical field [0001] The invention belongs to the technical field of shot blasting machines, and more specifically relates to a filtering device for a pass-through shot blasting machine. Background technique [0002] Shot blasting machine is a treatment technology that uses a shot blaster to drop shot material at high speed and impact on the surface of a material object. Compared with other surface treatment technologies, it is faster and more effective. The shot blasting machine can also be used to remove burrs and rust, and can also remove surface pollutants from a partially coated surface, and provide a surface profile that increases the adhesion of the coating to strengthen the workpiece. [0003] For example, the Chinese invention patent with the application number: CN201921075368.9, which discloses a pass-through shot blasting machine, including a shot blasting chamber and a conveying roller table. The conveying roller table is welded on one side of the shot blasting...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a filter device for a through-type shot blasting machine to solve the problem that the existing through-type shot blasting machine has open inlets and outlets at both ends of the workpiece, and the equipment itself only pours steel shots at both ends and passes through the shot blasting machine. There are two places in the pipeline, a total of four places are equipped with coarse filters, and the mixing of residues will lead to poor shot blasting effect. After shot blasting, the surface of the workpiece is covered with pits, which cannot meet the production needs. It will not affect the number of steel shots passing through when working, but it cannot solve the problem fundamentally, that is, the residue entering the workpiece inlet and outlet cannot be filtered, and if the steel shot that is originally provided with coarse filtration is installed in the pipeline, fine filtration will be used. The passing speed of the steel shot is too affected, which affects the passing efficiency of the steel shot
