[0002] After steel is forged, an oxide layer forms on its surface. In order to improve the surface quality of steel, the oxide scale on the steel surface needs to be removed. The common way to remove oxide scale is to use a shot peening device. The principle of shot peening is to use high-speed jets of cast steel shot or cast iron shot to remove the oxide scale on the steel surface.

The shot blasting chamber is provided with a support roller assembly and an installation frame. Multiple shot blasting pipes are evenly installed on the installation frame. A screening chamber is rotatably arranged below the power component. The power component is provided with a steel wire hose inserted into the screening chamber. A reciprocating rotation mechanism connected to the screening chamber is provided at the lower end of the power component. A conveying hose connected to the shot blasting pipe is provided in the power component. A discharge port is provided at the lower end of the shot blasting chamber. The discharge port is provided with a discharge pipe extending to the lower part of the power component. The end of the discharge pipe is connected to a hose connected to the screening chamber. A collection tray is provided below the power component.

[0004] During use, it was found that the device generates dust during steel feeding and discharging, and the dust collection effect is poor. The dust inhalation by workers affects their health. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a shot blasting device for removing oxide scale from the surface of steel.

[0006] This utility model discloses a shot blasting device for removing oxide scale from steel surfaces, comprising a shot blasting shell, dust covers, and a base frame. The shot blasting shell is mounted on the base frame, and a shot blasting assembly is disposed inside the shot blasting shell. Two sets of dust covers are respectively mounted on both sides of the shot blasting shell on the base frame. The device also includes a flexible sealing assembly, a conveying assembly, and a dust collection assembly. A flexible sealing assembly is disposed on each of the two sets of dust covers away from the feed inlet of the shot blasting shell. The conveying assembly is disposed on the base frame, and the dust collection assembly is disposed on the shot blasting shell. The dust collection assembly is used to absorb dust inside the two sets of dust covers. In use, the steel is placed on the support... On the frame, the support frame is placed on the conveying assembly. The conveying assembly is started, and the support frame and steel are conveyed synchronously. The steel frame and support frame pass through the flexible sealing assembly on a set of dust covers and enter the shot blasting shell. The shot blasting assembly sprays the steel, thereby removing the oxide scale from the steel surface. As the conveying assembly continues to convey, the processed steel and support frame pass through the flexible sealing assembly on a second set of dust covers. The two sets of flexible sealing assemblies keep the shot blasting shell and the two sets of dust covers sealed. The dust collection assembly is started, and the dust collection assembly adsorbs the dust inside the two sets of dust covers, improving environmental protection.

A set of positioning grooves is provided inside the material inlet of the dust cover, and each positioning groove has a round hole. Multiple sets of rubber plates are provided on the fixing plate, and a threaded groove is provided at the end of the fixing plate away from the rubber plates. The screw passes through the round hole and is threadedly connected to the threaded groove. Before use, the fixing plate is placed in the positioning groove, with the round hole coinciding with the threaded groove. The screw passes through the round hole and is threadedly connected to the threaded groove. The multiple sets of rubber plates on the two fixing plates cooperate to flexibly seal the material inlet of the dust cover. When the steel and support frame are conveyed into the inner side of the shot blasting shell through the conveying assembly, the multiple sets of rubber plates come into contact with the steel, and the rubber plates open adaptively. When the steel has completely entered the inner side of the dust cover and shot blasting shell, the multiple sets of rubber plates reset, and the multiple sets of rubber plates cooperate to reseal the material inlet of the dust cover, reducing dust leakage through the material inlet.

[0008] Preferably, the conveying assembly includes a rotating shaft, guide rollers, sprockets, chains, and a drive motor. Multiple sets of rotating shafts are rotatably arranged inside the base frame. Each set of rotating shafts is equipped with guide rollers, and each set of guide rollers is equipped with two sets of sprockets. Adjacent sets of sprockets are driven by chains. A drive motor is mounted on the base frame, and the output end of the drive motor is connected to one end of one set of rotating shafts. The drive motor is started by a controller, causing the multiple sets of rotating shafts to rotate synchronously and in the same direction with the cooperation of the corresponding sprockets and chains. The multiple sets of guide rollers also rotate synchronously and in the same direction, thereby conveying the steel and the support frame and improving conveying efficiency.

[0009] Preferably, the dust collection assembly includes a dust collection box, an exhaust fan, an exhaust pipe, a dust collection hopper, a discharge pipe, and a discharge valve. The shot blasting shell is equipped with a dust collection box.

A dust collection hopper is installed at the bottom of the dust collection box, and a discharge pipe is installed at the bottom of the dust collection hopper. A discharge valve is installed on the discharge pipe. When the shot blasting assembly inside the shot blasting shell generates dust during steel processing, a rubber plate flexibly seals the material inlet of the dust cover. The exhaust fan is activated, causing the dust inside the dust cover to be absorbed into the dust collection box through the exhaust pipe. With the help of the dust removal cloth, the dust falls into the dust collection hopper for collection. After a period of use, the discharge valve is opened, allowing the dust inside the dust collection hopper to be discharged through the discharge pipe, improving environmental friendliness.

[0010] Preferably, it also includes a protective cover, on which the bottom frame is provided, and multiple sets of sprockets and chains are located inside the protective cover; the multiple sets of sprockets and chains rotate inside the protective cover, and the protective cover prevents foreign objects and impurities from entering between the sprockets and chains, thereby improving the service life of the sprockets and chains.
