Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, and more specifically to a shot sand separator for a shot blasting machine. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot sand separation system of the shot blasting machine is usually used to separate qualified shot from unqualified shot in the form of slag, making it easy to separate and reuse the shot.

[0003] Based on the above, the inventors found that in the prior art, the shot materials are usually separated by a sieve, and then the unqualified shot materials are manually taken out after separation, which is inconvenient to operate and reduces the efficiency of shot sand screening. At the same time, dust often falls into the shot slag during the screening process. The shot slag needs to be cleaned before it is returned to the furnace for reuse. Incomplete cleaning will cause the quality of the shot materials to decrease, increasing the processing period and cost. Therefore, in view of this, the existing structure is studied and improved, and a shot sand separator for a shot blasting machine is provided, in order to achieve a more practical purpose.

[0026] See also Figure 3 The pitch of the spiral blade 1 7 is greater than the pitch of the spiral blade 2 8. When in use, the wide-pitch spiral blade 1 7 can realize rapid feeding of the pellets, while the narrow-pitch spiral blade 2 8 can quickly transport the screened pellets and crushed slag out of the feed barrel 2 5, thereby ensuring the separation effect and improving the screening efficiency.

[0032] During use: the pellets are sent to the feed barrel 3 through the feed hopper 10, and then the drive motor 9 is started. With the cooperation of the pulley group, the transmission shaft 6 can drive the spiral blade 1 7 and the spiral blade 2 8 to rotate. While the spiral blade 1 7 rotates, the pellets in the feed barrel 3 can be quickly transported to the feed barrel 2 5. After the pellets are vibrated and screened by the cylindrical screening net 11, qualified pellets fall into the pellet supply system, while unqualified pellets are transported to the other end of the feed barrel 2 5 by the rotating spiral blade 2 8 and discharged from the unloading hopper 13, realizing the function of automatically cleaning and recovering pellets and pellets, greatly improving the efficiency of pellet separation. At the same time, the external fan is connected to the dust removal port 12 on the screening box 4 through the air duct, and the fan is used to clean the dust in the screening process to reduce the dust from falling into the pellets and pellets, which is convenient for the cleaning and reuse of the pellets and pellets in the later stage.
