Description

Technical Field

[0001] This utility model relates to the field of shot recycling technology, specifically a shot recycling device for a shot blasting machine. Background Technology

[0002] In the field of metal surface treatment, shot blasting machines are a commonly used surface cleaning equipment, widely used in the surface treatment of large mechanical parts. They use shot to impact the surface of parts to remove impurities such as oxide scale and rust, thereby cleaning and strengthening the surface. During shot blasting, the recycling of shot is of great significance for ensuring the continuity of operations, improving production efficiency, and reducing costs. The shot recycling device of traditional shot blasting machines uses two sets of screw conveyors, one horizontal and one vertical, to transport the shot into the shot blasting machine.

[0003] In existing shot blasting machines, after the shot is processed, the surface of the shot is usually covered with impurities such as oxide scale and rust. If these impurities are not thoroughly removed, the shot used again will affect the shot blasting effect due to the presence of impurities, resulting in a decline in the surface cleaning quality of parts. In addition, when the shot is directly transported by two screw conveyors that cooperate horizontally and vertically, the mixed impurities tend to accumulate at the corners, making it difficult to clean the shot circulation device. Therefore, a shot circulation device for shot blasting machines is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a shot circulation device for a shot blasting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine shot circulation device, comprising: Shot blasting machine body; A screw conveyor, which is fixed to one side of the shot blasting machine body, is used for circulating and conveying shot. A feeding mechanism is fixed to the feeding port of the shot blasting machine body and is used to compress cleaning shot. A vibration cleaning mechanism is fixed at the lower end of the feeding mechanism and is used to vibrate and screen impurities in the pellets.

[0006] Preferably, the material feeding mechanism includes a material feeding channel and cleaning brush bristles. The material feeding channel is fixed to the feeding port of the shot blasting machine body, and the cleaning brush bristles are circumferentially fixed to the inner wall of the material feeding channel.

[0007] Preferably, the vibration cleaning mechanism includes a guide box, which is fixed to the lower end of the material discharge mechanism, and a slag discharge box is fixed to the bottom of the guide box.

[0008] Preferably, a screen plate is slidably connected inside the guide box, a lifting guide groove for raising and lowering the screen plate is provided on the inner side wall of the guide box, and a driving mechanism is provided below the screen plate.

[0009] Preferably, the driving mechanism includes a triangular prism, which is rotatably connected to the inner cavity of the guide box. A rotating shaft is fixed at the center of each end face of the triangular prism, and the rotating shaft passes through a bearing in the end wall of the guide box.

[0010] Preferably, a drive motor is fixed at the center of one end face of the guide box, and the output shaft of the drive motor is fixed at the end of a rotating shaft.

[0012] Preferably, the guide box has a discharge port at its lower inclined end, and a feeding hopper is fixed between the guide box and the screw conveyor. The guide box is connected to the screw conveyor through the feeding hopper.

[0013] This utility model provides a shot circulation device for a shot blasting machine, which has the following advantages compared with the prior art: With the feeding mechanism in place, when the shot passes through the feeding channel, the circumferentially fixed cleaning bristles on the inner wall will squeeze and clean the shot, scraping off some of the impurities attached to the surface of the shot, thus initially improving the cleanliness of the shot and reducing the burden of subsequent processing.

[0014] The vibration cleaning mechanism allows the triangular prism to periodically lift the screen plate, causing it to slide up and down within the lifting guide groove, creating a vibration effect. During this vibration, impurities in the shot, due to their different particle sizes, fall through the screen plate into the bottom slag discharge box. The vibration of the screen plate further cleans the shot, while qualified shot remains on the screen plate, effectively separating the shot from impurities and ensuring the quality of the recycled shot.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 This utility model provides a shot circulation device for a shot blasting machine, comprising: Shot blasting machine body 1; The screw conveyor 2 is fixed on one side of the shot blasting machine body 1. The screw conveyor 2 is used to circulate and transport shot. The feed hopper 5 is fixed between the guide box 7 and the screw conveyor 2. The guide box 7 is connected to the screw conveyor 2 through the feed hopper 5. The feeding mechanism 3 is fixed to the feeding port of the shot blasting machine body 1. The feeding mechanism 3 is used to squeeze the cleaning shot. The feeding mechanism 3 includes a feeding channel 16 and a cleaning brush 17. The feeding channel 16 is fixed to the feeding port of the shot blasting machine body 1. The cleaning brush 17 is circumferentially fixed on the inner wall of the feeding channel 16. The upper end face of the guide box 7 is provided with a feeding port 14. The feeding channel 16 is connected to the guide box 7 through the feeding port 14. The lower end of the guide box 7 is provided with a discharge port 15. After the shot blasting machine body 1 performs shot blasting on the parts, the used shot and impurities fall together from the feed port of the shot blasting machine body 1. At this time, when the shot passes through the feed channel 16, the cleaning brush bristles 17 fixed circumferentially on the inner wall will squeeze and clean the shot, scraping off some of the impurities attached to the surface of the shot, initially improving the cleanliness of the shot and reducing the burden of subsequent processing.

[0019] Vibration cleaning mechanism 4 is fixed at the lower end of the material dropping mechanism 3. Vibration cleaning mechanism 4 is used to vibrate and screen impurities in the pellets. Vibration cleaning mechanism 4 includes a guide box 7, which is fixed at the lower end of the material dropping mechanism 3. A slag discharge box 6 is fixed at the bottom of the guide box 7. A screen plate 8 is slidably connected inside the guide box 7. A lifting guide groove 13 for lifting the screen plate 8 is opened on the inner side wall of the guide box 7. A drive mechanism 9 is provided below the screen plate 8. The rotation of the triangular prism 10 periodically lifts the screen plate 8, causing it to slide up and down within the lifting guide groove 13, generating a vibration effect. During this vibration, impurities in the shot, due to their different particle sizes, fall through the screen plate 8 into the bottom slag box 6. The vibration of the screen plate 8 further cleans the shot, while qualified shot remains on the screen plate 8, achieving effective separation of shot and impurities and ensuring the quality of the recycled shot.

[0020] Further as Figure 4 As shown, it is worth noting that the drive mechanism 9 includes a triangular prism 10, which is rotatably connected in the inner cavity of the guide box 7. A rotating shaft 11 is fixed at the center of both ends of the triangular prism 10. The rotating shaft 11 passes through the bearing of the end wall of the guide box 7. A drive motor 12 is fixed at the center of one end of the guide box 7. The output shaft of the drive motor 12 is fixed at the end of the rotating shaft 11.

[0021] In metal surface treatment workshops, shot blasting machines are commonly used for cleaning the surfaces of large mechanical parts. To ensure the continuity of shot blasting operations and the efficient utilization of shot, the shot circulation device of the shot blasting machine plays a crucial role and has the following working process: After the shot blasting machine body 1 performs shot blasting on the parts, the used shot and impurities fall together from the feed port of the shot blasting machine body 1. At this time, when the shot passes through the feed channel 16, the cleaning brush bristles 17 fixed circumferentially on the inner wall will squeeze and clean the shot, scraping off some of the impurities attached to the surface of the shot, initially improving the cleanliness of the shot and reducing the burden of subsequent processing. After initial cleaning, the shot falls into the vibration cleaning mechanism 4 located at the lower end of the feeding mechanism 3. Inside the guide box 7, the drive motor 12 drives the rotating shaft 11 to rotate, which in turn causes the triangular prism 10 to rotate in the inner cavity of the guide box 7. As the triangular prism 10 rotates, its three sides periodically push up the screen plate 8, causing the screen plate 8 to slide up and down in the lifting guide groove 13, generating a vibration effect. During the vibration process, impurities in the shot, due to their different particle size from the shot, will fall into the slag discharge box 6 at the bottom through the screen plate 8. The vibration of the screen plate 8 can further clean the shot, while qualified shot remains on the screen plate 8, achieving effective separation of shot and impurities and ensuring the quality of the recycled shot.

[0022] After the shot is vibrated and cleaned, it slides from the inclined screen plate 8 into the feeding hopper 5 and finally enters the screw conveyor 2. The screw conveyor 2 is equipped with helical blades, which are tightly fixed on the rotating shaft to form a continuous helical structure. Under the thrust generated by the rotation of the helical blades, the shot is continuously pushed forward. As the helical blades continue to rotate, the shot is gradually transported from the feed end of the screw conveyor 2 to the discharge end located on one side of the shot blasting machine body 1, and finally re-enters the shot blasting machine body 1 for reuse, thus completing the task of circulating and transporting the shot.

[0023] During operation, the parts to be processed are fed into the processing area inside the shot blasting machine body (1). The shot blaster inside the shot blasting machine rotates at high speed and throws the stored shot at extremely high speed onto the surface of the parts. The shot blasting machine violently impacts the surface of the parts and removes rust, scale, oil and other impurities through impact and friction. At the same time, it creates a certain roughness on the surface of the parts, which enhances the adhesion of subsequent coatings or coatings and significantly improves the surface quality and service life of the parts.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Although embodiments of this utility model have been shown and described, this does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
