Description

TECHNICAL FIELD

[0001] The utility model relates to a through type shot blasting machine with shot blasting grit sorting mechanism. BACKGROUND

[0002] The shot blasting machine is a mechanical equipment for cleaning, strengthening or roughening the surface of workpieces by high-speed projectile pellets (such as steel shots, sand, etc.), and is widely used in the fields of casting, machining, metal surface treatment, etc., and the "through type" means that the workpieces pass through the processing area of the equipment in a continuous or intermittent manner, which is suitable for mass production and assembly line operation. After the shot blasting machine sprays sand to impact the surface of the workpiece to remove scale, rust, welding slag and other impurities, a sorting device is needed to separate the sand, broken sand, dust, workpiece debris and other impurities to ensure the purity of the recycled pellets.

[0003] Referring to the patent document CN114734378B, published on May 14, 2024, it includes a horizontally placed machine base, a conveying device for conveying workpieces is arranged on the machine base, a processing box is arranged on the machine base, a shot blasting machine is arranged on the side wall of the processing box, a recovery hopper is arranged at the bottom of the machine base, and a discharge bucket is arranged at the top of the processing box. The conveying device includes a conveying frame, rotating rollers and a chain. The conveying frame is arranged along the length direction of the machine base. The rotating rollers are arranged on the conveying frame along the length direction of the machine base. One end of the rotating roller is provided with a connecting gear. The chain is arranged on the rotating roller along the conveying frame. The chain is engaged with the connecting gear. The conveying frame is provided with a speed regulating device for controlling the rotating speed of the connecting gear. The speed regulating device adjusts the operating speed of the shot blasting machine according to the actual demand, so that the shot blasting machine is suitable for workpieces with different processing requirements. The present application has the function of improving the application range of the shot blasting machine.

[0004] However, the existing shot blasting machine usually uses a vibrating screen or a drum screen to separate the sand, broken sand, dust, workpiece debris and other impurities. The vibrating screen drives the screen surface to vibrate at a high frequency through mechanical vibration, so that materials of different particle sizes are classified according to the size difference of the screen holes. The drum screen uses a screen in the rotating drum to complete the screening of the materials during the rolling process. However, the separation effect is poor, which leads to a large amount of impurities mixed into the recycled sand, aggravates the wear of the blades and the guard plate of the shot blasting machine, and easily causes the fine impurities and the wet sand to adhere to the screen holes, causing the screen holes to be blocked, affecting the screening efficiency and quality.
