Abstract

The invention relates to a sand blasting device, which includes an input pipe, a sand feed pipe, a mixing box, and a main sand discharge pipe. The input pipe and the sand feed pipe form an acute angle, and are respectively communicated with one end of the mixing box. The main sand discharge pipe is equipped with a main sand outlet, and is communicated with the other end of the mixing box. The sand blasting device also includes an auxiliary sand discharge pipe consisting of a first auxiliary sand pipe and a second auxiliary sand pipe crookedly connected to the first auxiliary sand pipe. Besides, the first auxiliary sand pipe is communicated with the mixing box, the second auxiliary sand pipe is provided with an auxiliary sand outlet, and the axial extension line of the second auxiliary sand pipe and the axial extension line of the main sand discharge pipe intersect to form an acute angle. The sand blasting device provided in the invention can make a component force in the surface tangential direction have a strong stripping effect on a film on the component surface, so that high efficiency and rapid sand blasting effects can be realized.

Description

technical field [0001] The invention relates to a sandblasting device. Background technique [0002] Vacuum coating equipment such as turrets, hangers, fixtures for coating, coating equipment cavity, inner wall and inner lining board usually deposit thin films during the coating process, after long-term coating of vacuum coating equipment, the thin film will deposit A certain thickness will affect the coating effect of vacuum coating equipment. Therefore, it is usually necessary to regularly maintain the vacuum coating equipment, that is, usually use a sandblasting machine to remove the above-mentioned coating film. The sandblasting machine uses high-pressure air or high-pressure water to forcefully spray small-sized sand, and impacts the parts to be sandblasted at high speed to remove the coating film. However, the usual spraying method is to directly impact the sand on the surface film layer, and it is necessary to frequently adjust the angle of the spray gun according t...
