Technical Field
[0001] This utility model relates to the field of shot blasting machine separator technology, and in particular to a shot blasting machine separator structure with self-cleaning function. Background Technology
[0002] The shot blasting separator is a key component in shot blasting equipment. It is mainly used to separate the shot, dust and impurities after blasting, to ensure the purity of the shot used in recycling and to improve shot blasting efficiency.
[0003] As a core component for separating shot from impurities, the shot blasting separator's separation efficiency directly affects the shot blasting effect and cost. Currently, some existing separators use curtain plate adjustment mechanisms that are difficult to adjust precisely and conveniently using bolts. This results in the shot failing to form a uniform and stable flow curtain during its descent. For example, traditional full-curtain separators often adjust the curtain plate manually using a counterweight structure. When the shot flow rate, humidity, or particle size changes, the angle of the curtain plate cannot be adjusted in time, leading to uneven thickness and breakage of the flow curtain formed during shot descent. Consequently, the airflow and shot in the separation zone do not make sufficient contact, and light impurities cannot be effectively blown away. A large amount of sand, oxide scale, and other impurities are mixed into the qualified shot, significantly reducing the separation efficiency and thus lowering the practicality of the structure. Therefore, this utility model proposes a shot blasting separator structure with a self-cleaning function to solve the above problems. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a shot blasting machine separator structure with self-cleaning function, which solves the problem in the prior art where it is inconvenient to adjust the curtain plate using bolts, making it difficult for the shot to form a flow curtain and resulting in low shot separation efficiency.

A rotating wheel is installed at one end of the threaded rod. The other end of the threaded rod is rotatably connected to one end of the connecting plate.
[0007] A further improvement is that the limiting structure includes a limiting hole and a limiting rod. The limiting hole is opened through both ends of the fixed plate, and the limiting rod is installed through the inside of the limiting hole. One end of the limiting rod is connected to one end of the connecting plate.
[0008] A further improvement is that two limiting rods are provided at one end of the connecting plate, and the two limiting rods are symmetrically distributed about the central axis of the connecting plate.
[0009] A further improvement is that the cleaning mechanism includes an electric telescopic rod, a scraper, and a guide structure. The electric telescopic rod is installed on the inner side of the sieve plate, the scraper is installed on the front end of the sieve plate, the output end of the scraper extends to the inner side of the sieve plate, and the output end of the scraper is connected to one end of the electric telescopic rod.

[0011] A further improvement is that the cross-section of the guide groove is larger than the cross-section of the guide block, and the guide groove and the guide block form a sliding structure.
[0012] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism at the front end of the curtain plate, the adjustment mechanism utilizes the cooperation between the fixed rod, movable sleeve, connecting plate, fixed plate, threaded hole, threaded rod, rotating wheel, limiting hole, and limiting rod to rotate the rotating wheel and drive the threaded rod to move. With the cooperation of the fixed rod and movable sleeve, the angle of the curtain plate is adjusted, making it easier for the shot to form a flow curtain when it is fed, thus improving the separation effect of the shot and greatly improving the practicality of the structure in use. By setting a cleaning mechanism above the screen plate, the cleaning mechanism utilizes the cooperation between the guide groove, guide block, electric telescopic rod, and scraper to use the scraper to drive the electric telescopic rod to move and use the electric telescopic rod to automatically clean the screen plate. Therefore, it is more convenient and faster to clean larger impurities on the screen plate, thus greatly improving the convenience of the structure in use. Attached Figure Description

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a shot blasting machine separator structure with self-cleaning function, including a separator body 1, support legs 2 installed on the lower sides of both sides of the separator body 1, a feed inlet 3 installed on the upper side of one side of the separator body 1, a shot discharge outlet 4 installed at the lower front end of the separator body 1, an impurity discharge outlet 5 installed at the lower rear end of the separator body 1, a screen plate 6 installed at the front end of the middle position inside the separator body 1, a cleaning mechanism provided above the screen plate 6, an impurity discharge chamber 7 provided at the rear end of the middle position inside the separator body 1, a negative pressure fan 8 installed at the rear end of the separator body 1, and a curtain plate 9 rotatably installed inside the separator body 1, with an adjustment mechanism provided at the front end of the curtain plate 9.
[0020] The adjusting mechanism includes a fixed rod 10, a movable sleeve 11, a connecting plate 12, a fixed plate 13, a threaded hole 14, a threaded rod 15, a rotating wheel 16, and a limiting structure. The fixed rod 10 is installed inside the curtain panel 9. The movable sleeve 11 is provided on the outer wall of the fixed rod 10. The connecting plate 12 is hinged to the front end of the movable sleeve 11. The fixed plate 13 is installed inside the separator body 1. A threaded hole 14 is opened in the middle position inside the fixed plate 13. A threaded rod 15 is inserted through the threaded hole 14. A rotating wheel 16 is installed at one end of the threaded rod 15, and the other end of the threaded rod 15 is connected to... One end of the connecting plate 12 is rotatably connected. In use, rotating the wheel 16 drives the threaded rod 15 to rotate. Since the threaded hole 14 and the threaded rod 15 are threadedly connected, the threaded rod 15 moves inside the threaded hole 14. Then, under the limitation of the limiting hole 17 and the limiting rod 18, the threaded rod 15 drives the connecting plate 12 to move. At this time, the fixing rod 10 slides on the outer wall of the curtain plate 9, driving the curtain plate 9 to move and adjust the curtain plate 9 to an appropriate angle. At this time, the shot can form a flow curtain through the cooperation of the curtain plate 9, thus making the separation effect of the shot better and greatly improving the practicality of the structure in use.
[0021] The limiting structure includes a limiting hole 17 and a limiting rod 18. The limiting hole 17 is opened through both ends of the fixed plate 13. The limiting rod 18 is installed through the inside of the limiting hole 17. One end of the limiting rod 18 is connected to one end of the connecting plate 12. Two limiting rods 18 are provided at one end of the connecting plate 12. The two limiting rods 18 are symmetrically distributed about the central axis of the connecting plate 12. In use, the mutual cooperation between the limiting hole 17 and the limiting rod 18 can limit the movement of the connecting plate 12, making the connecting plate 12 more stable when moving.
[0022] The cleaning mechanism includes an electric telescopic rod 21, a scraper 22, and a guide structure. The electric telescopic rod 21 is installed on the inner side of the sieve plate 6, and the scraper 22 is installed at the front end of the sieve plate 6. The output end of the scraper 22 extends to the inner side of the sieve plate 6, and the output end of the scraper 22 is connected to one end of the electric telescopic rod 21. In use, the electric telescopic rod 21 is activated. Guided by the guide groove 19 and the guide block 20, the electric telescopic rod 21 drives the scraper 22 to move. The electric telescopic rod 21 scrapes larger impurities on the sieve plate 6 to the outer side of the sieve plate 6. Finally, the operator can manually remove them. The electric telescopic rod 21 automatically cleans the sieve plate 6, making it more convenient and faster to clean larger impurities on the sieve plate 6, thus greatly improving the ease of use of this structure.
[0023] The guiding structure includes a guide groove 19 and a guide block 20. The guide groove 19 is formed on both sides inside the separator body 1. The guide block 20 is provided inside the guide groove 19. One end of the guide block 20 is connected to one end of the scraper 22. The cross-section of the guide groove 19 is larger than the cross-section of the guide block 20. The guide groove 19 and the guide block 20 form a sliding structure. In use, the cooperation between the guide groove 19 and the guide block 20 can guide the scraper 22 when it moves, making the scraper 22 more stable when it moves.
[0024] Working principle: First, the operator feeds the material into the separator body 1 through the feed inlet 3. At this time, rotating the wheel 16 drives the threaded rod 15 to rotate. Because of the threaded connection between the threaded hole 14 and the threaded rod 15, the threaded rod 15 moves inside the threaded hole 14. Then, limited by the limiting hole 17 and the limiting rod 18, the threaded rod 15 drives the connecting plate 12 to move. Meanwhile, the fixing rod 10 slides on the outer wall of the curtain plate 9, moving the curtain plate 9 and adjusting it to an appropriate angle. At this point, the shot material, through the cooperation of the curtain plate 9, forms a flow curtain. Simultaneously, the negative pressure fan 8 is activated. The negative pressure fan 8 draws some low-density dust and impurities from the pellets into the impurity discharge chamber 7, and discharges them through the impurity discharge port 5. The high-density pellets and impurities fall onto the screen plate 6, where they are separated. The pellets are discharged through the pellet discharge port 4. When the screen plate 6 needs to be cleaned, the electric telescopic rod 21 is activated. Guided by the guide groove 19 and the guide block 20, the electric telescopic rod 21 moves the scraper 22, scraping larger impurities on the screen plate 6 to the outside of the screen plate 6. Finally, the workers can manually remove them.
