Description

TECHNICAL FIELD

[0001] The utility model relates to dust removal field, more particularly, relate to a kind of auxiliary device for reducing sand blasting machine dust. BACKGROUND

[0002] Sand blasting machine uses high-pressure airflow / vibration to drive abrasive (such as quartz sand) to impact workpiece at high speed, which can quickly remove surface rust layer, oxide scale and burrs, and roughen the substrate to enhance the adhesion of coating / plating layer. It is a key process for metal corrosion prevention and mechanical parts pretreatment. However, the breakage of abrasive and the separation of impurities during operation can generate metal / mineral dust. Insufficient airtightness or lack of dust removal will lead to dust dispersion, long-term inhalation or pneumoconiosis, and excessive metal dust concentration may trigger a fire explosion accident. Therefore, a corresponding dust removal device is needed for treatment.

[0003] After searching, the Chinese patent with patent announcement number CN203417900U discloses an auxiliary device for reducing sand blasting machine dust. The device includes an air inlet arranged on the side of the sand blasting machine feeding port, an air inlet connected to the air inlet of the dust collector through a pipeline, a gauze arranged on the air inlet, a sand recovery pipeline interface arranged below the gauze, and a sand recovery pipeline interface connected to the sand recovery container through a pipeline. The air inlet has a C-shaped structure. This auxiliary device for reducing sand blasting machine dust can absorb all the dust generated during the sand blasting process and recycle the materials in the dust. This dust removal device improves the working environment and reduces the waste of raw materials used in sand blasting. The device has the advantages of simple structure, good dust removal effect, and easy use.

[0004] (1) In actual use, the built-in gauze of the device is gradually clogged with dust due to long-term filtration of high-speed sand blasting dust, causing airflow obstruction and filtration failure. Maintenance is required, but the gauze assembly adopts a multi-layered long tube structure, which takes a long time to disassemble, flush and maintain.

[0005] (2) In actual use, the device only cleans the dust of the sand blasting machine by suction. The cleaning degree of dust by suction alone is not enough. The dust generated by sand blasting has inertia, and some dust may escape the suction air and enter the air. Therefore, an auxiliary device for reducing sand blasting machine dust is proposed.
