[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting machine shot circulation screening and dust removal device. Background Technology

[0002] In the field of machining, shot blasting machines, which use high-speed shot to impact the surface of workpieces to clean and strengthen them, are widely used in industries such as casting, forging, and machinery manufacturing. During the operation of a shot blasting machine, the shot circulation, screening, and dust removal device is a key component ensuring the efficient and stable operation of the equipment. Its function is to achieve the recycling of shot, while separating impurities and removing dust generated during the operation.

[0003] Existing equipment often requires multiple screenings of the shot to separate larger, deformed shot and smaller impurities. This significantly increases the time from shot blasting to recycling, lengthening the shot cycle. Furthermore, the continuous operation of multiple screening devices consumes more electricity, increasing energy costs. Therefore, we propose a shot blasting machine shot circulation screening and dust removal device to solve the above problems. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1-5 As shown, a shot blasting machine shot circulation screening and dust removal device includes a support frame 1, a box 11 fixedly connected to the top of the support frame 1, a feed hopper 12 fixedly connected to the left end of the box 11, dust removal mechanisms 13 installed on the front and back of the box 11, a screening component 2 provided inside the box 11, and a collection component 3 provided on the outer surface of the box 11.

[0025] The aforementioned dust removal mechanism 13 includes a dust collection chamber, filter elements, a fan, an air inlet duct, a dust removal device, a dust collection hopper, and a control system. When the device is working, the fan starts to create negative pressure to draw in dust-laden airflow. When passing through the dust collection chamber, dust particles of different sizes settle down or are intercepted by the filter elements. The dust removal device regularly removes the dust accumulated on the filter elements to ensure the filtration effect. Finally, the purified air is discharged, and the collected dust is centrally processed through the dust collection hopper to achieve efficient dust removal.

[0026] Specifically, in order to achieve the goal of completing the screening of projectiles in one go, see [reference needed]. Figure 2 and Figure 3 In this embodiment, the screening component 2 includes a screening cylinder 21. The left and right outer surfaces of the screening cylinder 21 are rotatably connected to the inner wall of the housing 11. The screening cylinder 21 is set with the left side higher than the right side. A motor 211 is fixedly connected to the right end of the housing 11, and a rotating shaft 212 is fixedly connected to the output end of the motor 211.

[0027] Further reading Figure 3 In this embodiment, the outer surface of the rotating shaft 212 is rotatably connected to the inner wall of the box 11, a gear 213 is fixedly connected to the left end of the rotating shaft 212, an external gear ring 214 is fixedly connected to the outer surface of the screening cylinder 21, the top of the external gear ring 214 is meshed with the bottom of the gear 213, and a spiral blade 215 is fixedly connected to the inner wall of the screening cylinder 21.

[0028] Further reading Figure 4 In this embodiment, a screening cylinder 22 is rotatably connected to the inner wall of the box 11. A plurality of fixing frames 221 are fixedly connected to the inner wall of the screening cylinder 22. The inner walls of the plurality of fixing frames 221 are all fixedly connected to the outer surface of the screening cylinder 21.

[0029] Further reading Figure 2 and Figure 4 In this embodiment, a discharge hole is provided at the bottom right side of the screening cylinder 22, and a discharge rack 23 is fixedly connected to the inner wall of the bottom of the box 11. The discharge rack 23 is located directly below the discharge hole.

[0030] During implementation, when screening the used projectiles is required, the projectiles are first fed into the feed hopper 12. The projectiles entering the feed hopper 12 are then discharged into the screening cylinder 21 through the conveying pipe at its bottom. The motor 211 is turned on, driving the rotating shaft 212 to rotate within the inner wall of the housing 11. The rotation of the rotating shaft 212 drives the gear 213 to rotate, which in turn drives the screening cylinder 21 to rotate within the inner wall of the housing 11 via the external gear ring 214. Since the screening cylinder 21 is designed with a left-high, right-low profile, the projectiles move to the right within the screening cylinder 21 as it rotates. Because the screening cylinder 21 has spiral blades 215 inside, it increases the residence time of the projectiles within the screening cylinder 21. As the projectiles move to the right, normal projectiles and smaller impurities pass through the screening cylinder 21. The through holes on the surface allow the pellets to enter the screening cylinder 22. Larger pellets that have deformed will remain inside the screening cylinder 21 and be discharged through the opening on the right side of the screening cylinder 21. When the screening cylinder 21 rotates, it will drive the screening cylinder 22 to rotate within the inner wall of the housing 11 through several fixed frames 221. As the screening cylinder 22 rotates, smaller impurities will fall into the bottom of the inner wall of the housing 11 through the through holes on the surface of the screening cylinder 22, while the larger pellets will accumulate on the right side of the inner wall of the screening cylinder 22. As the screening cylinder 22 rotates, it can be discharged into the discharge frame 23 through the discharge hole on the right side of the screening cylinder 22. This allows the device to screen out larger pellets that have deformed and smaller impurities in one go, which not only avoids multiple screenings and waiting times and reduces the pellet circulation cycle, but also reduces the energy consumption of the device per screening.

[0031] Example 2: This example sets up a collection component based on Example 1.

[0032] Specifically, in order to facilitate the cleaning of the screened objects by staff, please refer to... Figure 1 and Figure 5In this embodiment, the collecting component 3 includes a discharge hopper 31, the top outer surface of the discharge hopper 31 is fixedly connected to the bottom inner wall of the box 11, and a collecting cylinder 32 is provided on the right side of the box 11, the collecting cylinder 32 is located directly below the right opening of the screening cylinder 21.

[0033] Further reading Figure 5 In this embodiment, a discharge pipe 321 is fixedly connected to the bottom of the collection cylinder 32, and a plurality of connecting brackets 322 are fixedly connected to the outer surface of the discharge pipe 321. One end of each of the connecting brackets 322 near the center of the box 11 is fixedly connected to the outer surface of the box 11.

[0034] Further reading Figure 5 In this embodiment, the top of the support frame 1 is fixedly connected to two slide rails 331, and the inner walls of the two slide rails 331 are slidably connected to a collection drawer 33, and the top of the collection drawer 33 has two storage slots.

[0035] During implementation, larger deformed projectiles are discharged into the collection cylinder 32 through the opening on the right side of the screening cylinder 21. The discharge pipe 321 fixed at the bottom of the cylinder collects the projectiles into the storage slot on the left side of the collection drawer 33. Smaller solid impurities gradually move to the right side of the bottom of the inner wall of the box 11 and are discharged into the storage slot on the right side of the collection drawer 33 through the discharge hopper 31. This allows workers to clean the projectiles quickly and easily, simplifying the cleaning process and reducing the workload of workers. Furthermore, by dividing the waste into sections, it is convenient to count the projectile losses and provide a reference for consumable replenishment and process adjustment.

[0036] The working principle of this utility model is as follows: When it is necessary to screen the used projectiles, the projectiles are first fed into the feed hopper 12. The projectiles entering the feed hopper 12 will be discharged into the screening cylinder 21 through the conveying pipe at the bottom. The motor 211 is turned on to drive the rotating shaft 212 to rotate in the inner wall of the housing 11. When the rotating shaft 212 rotates, it drives the gear 213 to rotate. When the gear 213 rotates, it drives the screening cylinder 21 to rotate in the inner wall of the housing 11 through the external gear ring 214. Since the screening cylinder 21 is set with the left side higher than the right side, the projectiles will move to the right inside the screening cylinder 21 as it rotates. Since the screening cylinder 21 is equipped with spiral blades 215, it can increase the residence time of the projectiles inside the screening cylinder 21. As the projectiles move to the right, normal projectiles and smaller impurities will pass through the screening cylinder 21. The through holes on the surface of screen 21 allow the pellets to enter the interior of screen cylinder 22. Larger pellets that have deformed will remain inside screen cylinder 21 and be discharged through the opening on the right side of screen cylinder 21. When screen cylinder 21 rotates, it will drive screen cylinder 22 to rotate within the inner wall of box 11 through several fixed frames 221. As screen cylinder 22 rotates, smaller impurities will fall into the bottom of the inner wall of box 11 through the through holes on the surface of screen cylinder 22, while larger pellets will accumulate on the right side of the inner wall of screen cylinder 22. As screen cylinder 22 rotates, it can be discharged into the discharge frame 23 through the discharge hole on the right side of screen cylinder 22. This allows the device to screen out larger pellets that have deformed and smaller impurities in one go, which not only avoids multiple screenings and waiting times and reduces the pellet circulation cycle, but also reduces the energy consumption of the device per screening.

[0037] Larger, deformed projectiles are discharged into the collection cylinder 32 through the opening on the right side of the screening cylinder 21. They are then collected into the storage slot on the left side of the collection drawer 33 via the discharge pipe 321 fixed at its bottom. Smaller solid impurities gradually move to the right from the bottom of the inner wall of the box 11 and are discharged into the storage slot on the right side of the collection drawer 33 via the discharge hopper 31. This allows workers to clean them quickly and easily, simplifying the cleaning process, reducing the workload of workers, and facilitating the collection of different types of waste by dividing the area for easy statistics on projectile wear, providing a reference for consumable replenishment and process adjustment.

[0038] While the device is working, two dust removal mechanisms 13 can remove the dust generated during the screening process, thus preventing the dust from spreading to the outside.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
