Description
Technical field
The present invention relates to a kind of shakeout, more particularly to a kind of new shakeout with dedusting and denoising structure.
Background technology
Usually all it is to be separated molding sand with casting using vibrating type sand-dropping machine in foundary industry, but this shakes
Dynamic formula shakeout can produce substantial amounts of dust when carrying out desanding to cast(ing) surface, while can also produce strong vibration noise,
This can cause the body of operator very big harm, while also can surrounding enviroment be caused with serious pollution.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of new shakeout with dedusting and denoising structure, can
Prevent the flour dust overflow produced during casting falling sand, and carry out effective concentrate and discharge, while casting falling sand mistake can be reduced
The noise produced in journey, can prevent dust and noise pollution workshop condition, so as to avoid dust and the body of noise hazard worker
Body health.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of new shakeout with dedusting and denoising structure, including the noise reduction being arranged on the shakeout grate bed of shakeout body
Dust excluding hood, the noise reduction dust excluding hood are rectangle groove profile, and the noise reduction dust excluding hood is made of acoustical panel, the length of the noise reduction dust excluding hood
Degree is consistent with the length of shakeout grate bed, and baffle has been respectively articulated with the length direction both ends port of the noise reduction dust excluding hood, described
