Sand blasting device

Abstract

The invention relates to the technical field of polishing, and discloses a sand blasting device. The sand blasting device comprises a housing and a sand outlet pipe. The housing is provided with a sand inlet, a sand blasting port and an air return port, the sand inlet and the sand blasting port are oppositely arranged and located on the same horizontal line, the sand blasting port is provided withdustproof fluff. The sand outlet pipe is connected to the lower side of the housing and communicates with the interior of the housing, the side, facing the sand inlet, of the sand outlet pipe is obliquely arranged downwards, and the included angle between the axis of the sand outlet pipe and the horizontal axis of the housing is alpha which is greater than or equal to 45 degrees and less than orequal to 90 degrees. The sand blasting device can be well attached to the surface of equipment, shortens the manual sand cleaning time, reduces the labor intensity of workers and avoids contaminationto the air environment and the ground.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a sand washing device. Background technique [0002] In the current shipbuilding field, the sand washing device is one of the essential equipment. During the sand washing process, a large amount of steel sand will be scattered, and the staff often need to spend more time and labor than sand washing to clean up the fallen steel sand. When performing sand washing operations outdoors, the staff must take precautions in advance to prevent steel grit from scattering and dust from overflowing. That is to say, the air environment and the ground will be polluted during sand washing, and the workload of manual sand removal is large. Moreover, when the steel grit is ejected, it has a relatively large momentum, so that the staff cannot fit the sand washing device to the surface of the equipment to be sand washed. In addition, the surface of some equipment to be sand-washed and rust-remo...

Problems solved by technology

That is to say, the air environment and the ground will be polluted during sand washing, and the workload of manual sand removal is large.

Moreover, when the steel grit is ejected, it has a relatively large momentum, so that the staff cannot fit the sand washing device to the surface of the equipment to be sand washed.

In addition, the surface of some equipment to be sand-washed and derusted may also have a radian, which is not a plane, and it is difficult for the current sand-washing device to fit it
