2. Description:

Shot blasting and cleaning cabinet consists of main and assistant cabinets. Main cabinet is welded by 12mm steel plate and profile steel, with characteristic of high intensity, good rigidity and little vibration. There is one wearing protective chromium plate in the main cabinet inner wall, which is installed by bolts and changed conveniently. Assistant cabinet is also welded by steel plate and profile steel with good rigidity and intensity, and can reduce noise effectively.

In order to prevent shot and dust overflowing, five flexible baffles like finger is set at cabinet input and output end, which is composed of 2mm spring steel plate and 5mm double-layer wearing rubber through coining. Finger-like baffles can prevent shot spattering efficiently and have excellent performance-price ratio and useful lifetime. Meanwhile, it will reduce opening size and gap area at cabinet entrance and exit end so as to make wind speed of dust removing system more than 5m/s to increase dust removal effect, which is lager than dust overflowing speed.

Dust collection is mounted in top part and lower side of entrance and exit terminal in shot blasting cabinet. Dust collection connects with dust removing system and the cleaning cabinet is in sub pressure state, which can assure no dust overflow.

Impeller head is mounted at the side of up and down, left and right, whose position is designed by computer according to processed components character to decide the best location. After work-piece entering into cabinet, shot giving valve starts working and impeller head begin to blast shot to work-piece at different position, attachment and remained welding slag of work-piece surface will be cleaned up rapidly.

Impeller head starts to work selectively on basis of work-piece specification and shape. 8 impeller heads are able to work at the same time when blast big and complicated work-piece; For small and simple work-piece, you can select relative impeller heads to work.
