Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting rust removal, and particularly to a shot slag separation shot blasting device and a shot blasting process for steel shot rust removal. Background Art

[0002] With the rapid development of modern industry, metal products are widely used in various fields, such as mechanical manufacturing, automotive industry, shipbuilding, bridge construction, etc. During the production, storage, and use of these metal products, they are prone to oxidation, corrosion, etc., and rust layers and scale will form on the surface. The rust layer not only affects the appearance of metal products but also reduces their performance and service life. In order to ensure the quality and reliability of metal products, rust removal treatment is required. Shot blasting technology is a surface treatment technology that uses a high-speed rotating shot blasting machine to project projectiles (such as steel shots) onto the surface of workpieces, and removes impurities such as rust layers and scale on the surface of workpieces through the impact force of the projectiles.

[0003] During the shot blasting rust removal process, shot slag separation is a key link. In the early stage, shot slag separation mainly relied on simple screen filtration, and the separation effect was not ideal, which easily led to impurities in the steel shots, affecting the rust removal effect and the service life of the steel shots. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A shot slag separation shot blasting device and a shot blasting process for steel shot rust removal, including: A conveying frame, the top of the conveying frame is fixedly connected with a connecting housing, both sides of the connecting housing are equipped with shielding curtains, the side of the connecting housing is fixedly connected with a first motor, and the top of the inner cavity of the connecting housing is fixedly connected with a shot blasting component; A recycling component, which is used to recycle the steel shots ejected by the shot blasting component, and the side of the recycling component is fixedly connected with the inner side of the connecting housing; The recycling component includes a recycling box, a feeding housing, and a second motor. The side of the recycling box is fixedly connected with the inner side of the connecting housing. A first spiral blade is rotatably connected to the side of the recycling box. A driving member is fixedly connected to the side of the connecting housing, and the output end of the driving member is fixedly connected to one end of the first spiral blade. A feeding port is opened on one side of the recycling box close to the feeding housing. Belt wheels are rotatably connected to both sides of the inner cavity of the feeding housing. A feeding belt is sleeved on the belt wheels. A recycling hopper is fixedly connected to the side of the feeding belt. The side of the second motor is fixedly connected with the inner side of the connecting housing, and the output end of the second motor is fixedly connected with the side of the lower belt wheel. An outlet is opened at the top of the feeding housing; Preferably, when the shot blasting machine performs shot blasting and rust removal operations on the H-beam webs continuously conveyed by the conveying rack, the steel shots shot onto the workpiece surface fall together with the rust slag and other impurities that are knocked off, and enter the funnel-shaped recovery box. At this time, the driving member connected to the side of the housing is turned on, and its output end drives the first spiral blade to rotate in the inner cavity of the recovery box, and continuously conveys the steel shots gathered in the recovery box to the inner cavity of the feeding housing through the feeding port; Preferably, the shot blasting component includes a shot blasting housing, the side of the shot blasting housing is fixedly connected to the inner side of the connecting housing, a fixing block is fixedly connected to the inner side of the shot blasting housing, a separating mechanism is fixedly connected to the side of the fixing block, and a discharging mechanism is fixedly connected to the bottom of the inner cavity of the shot blasting housing. The discharging mechanism is arranged below the separating mechanism; Preferably, after the steel shots continuously enter the separating mechanism through the discharging port, the separating mechanism is immediately started to efficiently separate the steel shots from the impurities. While the separation operation is completed, the discharging mechanism operates synchronously to collect the separated pure steel shots and impurities respectively, avoiding the residual accumulation of steel shots and impurities in the equipment, ensuring both the efficiency of steel shot recycling and the centralized treatment of impurities, and ensuring the cleanliness of the working environment of the shot blasting equipment; Preferably, the separating mechanism includes a separating cylinder, one side of the separating cylinder away from the connecting box is fixedly connected to the fixing block, a connecting box is fixedly connected to the side of the separating cylinder, a square groove is opened on one side of the connecting box close to the discharging port, the side of the connecting box away from the separating cylinder is fixedly connected to the inner side of the shot blasting housing, a second spiral blade is rotatably connected to the inner side of the connecting box, the output end of the first motor is fixedly connected to one end of the second spiral blade away from the recovery cylinder, one end of the second spiral blade away from the inner side of the connecting box is rotatably connected to the inner side of the separating cylinder, and a blanking component is fixedly connected to the bottom of the separating cylinder; Preferably, when the steel shots continuously enter the connecting box through the discharging port, the first motor is started, and its output end drives the second spiral blade to rotate in the connecting box and the separating cylinder. The second spiral blade continuously conveys the steel shots in the connecting box to the separating cylinder, and at the same time drives the steel shots to rotate and stir in the separating cylinder. Through this mechanical stirring and centrifugal action, the efficient separation of steel shots and shot slag is realized, integrating the conveying and separation processes, reducing the floor area of the equipment and the material transfer links, and effectively improving the working efficiency. Since the steel shots have a large self-gravity, the separated steel shots will be smoothly discharged through the blanking component. By combining mechanical stirring and gravity separation, compared with the traditional separation method relying on single gravity sedimentation, the accuracy of shot slag separation is greatly improved, ensuring that the recovered steel shots have a higher purity, can better meet the requirements of subsequent shot blasting and rust removal work, guarantee the shot blasting quality, and reduce the risk of workpiece surface damage caused by impurity residue; Preferably, the blanking component includes a discharge rack, the side surface of the discharge rack is fixedly connected to the inner side of the separation cylinder, a rotating shaft is rotatably connected to the inner side of the discharge rack, and a straight plate is fixedly connected to the side surface of the rotating shaft; Preferably, the steel shots falling from the separation cylinder continuously roll downward along the discharge rack. During the falling process, the steel shots come into contact with and impact the straight plate inside the discharge rack. Since the straight plate is connected to the rotating shaft, when being impacted by the steel shots, it will drive the rotating shaft to rotate inside the discharge rack. The straight plate is made of rubber material, which has good elasticity and wear resistance. When the steel shots impact the straight plate, it can not only generate sufficient impact force to further separate the steel shots from the residual shot slag, but also effectively buffer the impact force, avoid the steel shots from being broken due to excessive impact, and reduce the loss of steel shots. During this impact process, some fine shot slag attached to the surface of the steel shots or mixed with the steel shots will be separated, realizing the secondary fine separation of the steel shots, further improving the purity of the steel shots, providing higher-quality steel shots for the subsequent shot blasting and rust removal work, ensuring the stability and durability of the shot blasting effect, and at the same time reducing the wear of the key components of the shot blasting equipment caused by impurities and extending the service life of the equipment; Preferably, the discharging mechanism includes a blanking rack, a shot blasting machine and a collection box. The side surface of the blanking rack is fixedly connected to the inner side of the shot blasting housing. A shielding rack is fixedly connected to the side surface of the blanking rack. A notch corresponding to the top inlet of the shot blasting machine is formed on the side surface of the shielding rack. Fans are evenly arranged on the side surface of the blanking rack, and the side surface of the fans is fixedly connected to the inner side of the blanking rack. The side surface of the shot blasting machine is fixedly connected to the bottom of the inner cavity of the shot blasting housing. The side surface of the collection box is fixedly connected to the bottom of the inner cavity of the shot blasting housing. A baffle is fixedly connected to the top of the collection box; Preferably, when the steel shots and the shot slag continuously move downward in the discharge rack, start the fans, and the airflow generated by their operation will act on the mixture of the steel shots and the shot slag. Since the steel shots have a greater self-weight, they can continue to slide downward along the discharge rack; while the shot slag with a smaller density will be blown away by the airflow. This method of separating by using airflow cleverly takes advantage of the difference in weight between the steel shots and the shot slag, realizes a non-contact and low-energy-consuming separation process, avoids the wear of the steel shots that may be caused by traditional mechanical separation, and effectively reduces the cost of steel shot loss.

[0005] The present invention provides a technical solution: a shot slag separation shot blasting process for steel shot rust removal, including the following steps: S1: Clamp the workpiece on the conveying rack of the shot blasting machine; S2: The workpiece to be processed is sent into the working area of the shot blasting machine through the conveying rack. The impeller rotating at a high speed inside the shot blasting component accelerates the steel shots to a certain speed and then projects them onto the surface of the workpiece, and uses the impact force of the steel shots to remove the rust layer, scale and other impurities on the surface of the workpiece to achieve the purpose of rust removal; S3: The steel shots projected onto the workpiece surface and impurities such as the knocked-off rust slag fall together and enter the recovery component located at the bottom of the connection housing. The recovery component is usually a funnel-shaped structure that can centrally collect the steel shots and impurities for subsequent recycling processes. S4: The collected steel shots and impurities are lifted by the recovery component from the recovery component to the feeding position of the shot blasting component. S5: The lifted steel shots and impurities enter the shot blasting component. Due to the relatively large density of the steel shots, under the combined action of gravity and air flow, they will fall along a specific channel and re-enter the shot blaster. While impurities such as rust slag have a smaller density and will be carried by the air flow to other channels and enter the waste collection box, thus realizing the separation of steel shots and rust slag. S6: The separated clean steel shots enter the shot blaster and participate in the shot blasting and rust removal process of the workpiece in a cycle, realizing the multiple reuse of steel shots and reducing production costs.

[0006] The present invention provides a shot slag separation shot blasting device and a shot blasting process for steel shot rust removal, having the following beneficial effects: 1. For the shot slag separation shot blasting device and the shot blasting process for steel shot rust removal, a recovery component is provided. The recovery hopper provided on the feeding belt will continuously lift the steel shots entering the feeding housing as the feeding belt rotates. Some larger impurities will fall at the bottom of the feeding housing or midway due to gravity. By using the gravity principle, the preliminary separation of large particle impurities from the steel shots is realized, reducing the burden of subsequent shot slag separation work and improving the separation efficiency.

[0007] 2. For the shot slag separation shot blasting device and the shot blasting process for steel shot rust removal, a separation mechanism is provided. The second spiral blade continuously transports the steel shots in the connection box to the separation cylinder, and at the same time drives the steel shots to rotate and stir in the separation cylinder. Through this mechanical stirring and centrifugal action, the efficient separation of steel shots and shot slag is realized, integrating the transportation and separation processes, reducing the floor area of the equipment and the material transfer link, and effectively improving the work efficiency. Since the gravity of the steel shots themselves is relatively large, the separated steel shots will be smoothly discharged through the blanking component. By combining mechanical stirring and gravity separation, compared with the traditional separation method relying solely on gravity sedimentation, the accuracy of shot slag separation is greatly improved, ensuring that the recovered steel shots have a higher purity, can better meet the requirements of subsequent shot blasting and rust removal work, guarantee the shot blasting quality, and reduce the risk of workpiece surface damage caused by impurity residue.

[0008] 3. The shot blasting equipment and shot blasting process for separating shot and slag used for steel shot rust removal are provided with a feeding component. The straight plate is made of rubber material, which has good elasticity and wear resistance. When the steel shot impacts the straight plate, it can not only generate sufficient impact force to further separate the steel shot from the residual shot and slag, but also effectively buffer the impact force, avoiding the breakage of the steel shot due to excessive impact and reducing the loss of steel shot. During this impact process, some fine shot and slag attached to the surface of the steel shot or mixed with the steel shot will be separated, realizing the secondary fine separation of the steel shot, further improving the purity of the steel shot, providing higher-quality steel shot for the subsequent shot blasting rust removal work, ensuring the stability and durability of the shot blasting effect, and at the same time reducing the wear of the key components of the shot blasting equipment caused by impurities and extending the service life of the equipment.

[0009] 4. The shot blasting equipment and shot blasting process for separating shot and slag used for steel shot rust removal are provided with a discharging mechanism. When the steel shot and the shot and slag continuously move downward in the discharging rack, start the fan. The airflow generated by its operation will act on the mixture of steel shot and shot and slag. Due to the relatively large self-weight of the steel shot, it can continue to slide downward along the discharging rack; while the shot and slag with relatively small density will be blown away by the airflow. This method of separating by using airflow skillfully takes advantage of the difference in weight between the steel shot and the shot and slag, realizing a non-contact and low-energy-consuming separation process, avoiding the wear of the steel shot that may be caused by traditional mechanical separation, and effectively reducing the cost of steel shot loss.

Detailed implementation manners

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figures 1 - 2 , the present invention provides a technical solution: a shot slag separation shot blasting device for steel shot rust removal, including: A conveying frame 1, the top of the conveying frame 1 is fixedly connected with a connecting housing 2, shielding curtains 3 are installed on both sides of the connecting housing 2, a first motor 6 is fixedly connected to the side of the connecting housing 2, and a shot blasting component 4 is fixedly connected to the top of the inner cavity of the connecting housing 2; A recovery component 5, which is used to recover the steel shots ejected by the shot blasting component 4, and the side of the recovery component 5 is fixedly connected to the inner side of the connecting housing 2; Please refer to Figures 1 - 4 , the recovery component 5 includes a recovery box 51, a feeding housing 53 and a second motor 52. The side of the recovery box 51 is fixedly connected to the inner side of the connecting housing 2. A first spiral blade 59 is rotatably connected to the side of the recovery box 51. A driving member is fixedly connected to the side of the connecting housing 2, and the output end of the driving member is fixedly connected to one end of the first spiral blade 59. A feeding port 57 is opened on one side of the recovery box 51 close to the feeding housing 53. Pulley 54 is rotatably connected to both sides of the inner cavity of the feeding housing 53, a feeding belt 55 is sleeved on the pulley 54, a recovery hopper 56 is fixedly connected to the side of the feeding belt 55, the side of the second motor 52 is fixedly connected to the inner side of the connecting housing 2, and the output end of the second motor 52 is fixedly connected to the side of the lower pulley 54. A discharging port 58 is opened at the top of the feeding housing 53; When the shot blasting machine performs shot blasting and rust removal operations on the H-beam webs continuously conveyed by the conveying frame 1, the steel shots shot onto the workpiece surface and impurities such as knocked-off rust slag fall together and enter the funnel-shaped recovery box 51. At this time, the driving part connected to the side of the housing 2 is turned on, and its output end drives the first spiral blade 59 to rotate in the inner cavity of the recovery box 51, and the steel shots gathered in the recovery box 51 are continuously conveyed to the inner cavity of the feeding housing 53 through the feeding port 57; After the second motor 52 is turned on, its output end drives the pulley 54 to rotate, and the pulley 54 further drives the feeding belt 55 to operate. The recovery hopper 56 arranged on the feeding belt 55 will continuously lift the steel shots entering the feeding housing 53 as the feeding belt 55 rotates. Some larger impurities will fall at the bottom or midway of the feeding housing 53 due to gravity. Using the principle of gravity, the preliminary separation of large-particle impurities from the steel shots is realized, reducing the burden of subsequent shot-slag separation work, improving the separation efficiency. The lifted steel shots enter the connection box 422 through the discharge port 58 for further shot-slag separation work. This integrated structural design of feeding and preliminary separation not only ensures the efficient conveyance of steel shots, but also reduces the wear risk of key components inside the equipment by removing large-particle impurities in advance, extends the service life of the equipment, and reduces the loss caused by the mixing of steel shots and impurities, improving the economy of steel shot recycling; Please refer to Figures 1 - 5 As shown in, the present invention provides a technical solution: The shot blasting component 4 includes a shot blasting housing 41, the side of the shot blasting housing 41 is fixedly connected to the inner side of the connection housing 2, a fixed block 43 is fixedly connected to the inner side of the shot blasting housing 41, a separation mechanism 42 is fixedly connected to the side of the fixed block 43, and a discharge mechanism 44 is fixedly connected to the bottom of the inner cavity of the shot blasting housing 41. The discharge mechanism 44 is arranged below the separation mechanism 42; After the steel shots continuously enter the separation mechanism 42 through the discharge port 58, the separation mechanism 42 is immediately started to efficiently separate the steel shots and impurities. While the separation operation is completed, the discharge mechanism 44 operates synchronously to collect the separated pure steel shots and impurities respectively, avoiding the residual accumulation of steel shots and impurities in the equipment, ensuring both the efficiency of steel shot recycling and the centralized treatment of impurities, and ensuring the cleanliness of the working environment of the shot blasting equipment; Please refer to Figures 1 - 6, the separating mechanism 42 includes a separating cylinder 421. One side of the separating cylinder 421 away from the connection box 422 is fixedly connected to a fixed block 43. A connection box 422 is fixedly connected to the side surface of the separating cylinder 421. A square groove is formed on one side of the connection box 422 close to the discharge port 58. One side of the connection box 422 away from the separating cylinder 421 is fixedly connected to the inner side of the shot blasting housing 41. A second spiral blade 423 is rotatably connected to the inner side of the connection box 422. The output end of the first motor 6 is fixedly connected to one end of the second spiral blade 423 away from the recovery cylinder 424. One end of the second spiral blade 423 away from the inner side of the connection box 422 is rotatably connected to the inner side of the separating cylinder 421. A blanking assembly 425 is fixedly connected to the bottom of the separating cylinder 421; When the steel shots continuously enter the connection box 422 through the discharge port 58, start the first motor 6. Its output end drives the second spiral blade 423 to rotate in the connection box 422 and the separating cylinder 421. The second spiral blade 423 continuously conveys the steel shots in the connection box 422 to the separating cylinder 421, and at the same time drives the steel shots to rotate and stir in the separating cylinder 421. Through this mechanical stirring and centrifugal action, the efficient separation of steel shots and shot slag is realized, integrating the conveying and separation processes, reducing the floor area of the equipment and the material transfer links, and effectively improving the working efficiency. Due to the relatively large self-gravity of the steel shots, the separated steel shots will be smoothly discharged through the blanking assembly 425. By combining mechanical stirring and gravity separation, compared with the traditional separation method relying solely on gravity sedimentation, the accuracy of shot slag separation is greatly improved, ensuring that the recovered steel shots have a higher purity, better meeting the requirements of subsequent shot blasting and rust removal work, guaranteeing the shot blasting quality, and reducing the risk of workpiece surface damage caused by impurity residue; Please refer to Figures 1 - 7 , the blanking assembly 425 includes a discharge rack 4251. The side surface of the discharge rack 4251 is fixedly connected to the inner side of the separating cylinder 421. A rotating shaft 4252 is rotatably connected to the inner side of the discharge rack 4251. A straight plate 4253 is fixedly connected to the side surface of the rotating shaft 4252; The steel shots that fall from the separation cylinder 421 continuously roll downward along the discharge rack 4251. During the falling process, the steel shots come into contact with and impact the straight plate 4253 inside the discharge rack 4251. Since the straight plate 4253 is connected to the rotating shaft 4252, when being impacted by the steel shots, it will drive the rotating shaft 4252 to rotate inside the discharge rack 4251. The straight plate 4253 is made of rubber material, which has good elasticity and wear resistance. When the steel shots impact the straight plate 4253, it can not only generate sufficient impact force to further separate the steel shots from the residual shot slag, but also effectively buffer the impact force, avoid the steel shots from being broken due to excessive impact, and reduce the loss of steel shots. During this impact process, some fine shot slag attached to the surface of the steel shots or mixed with the steel shots will be separated, realizing the secondary fine separation of the steel shots, further improving the purity of the steel shots, providing higher-quality steel shots for the subsequent shot blasting and rust removal work, ensuring the stability and durability of the shot blasting effect, while reducing the wear of the key components of the shot blasting equipment caused by impurities and extending the service life of the equipment; Please refer to Figures 1 - 8 , the discharging mechanism 44 includes a blanking rack 441, a shot blasting machine 446 and a collection box 445. The side of the blanking rack 441 is fixedly connected to the inner side of the shot blasting shell 41. A shielding rack 442 is fixedly connected to the side of the blanking rack 441. A notch corresponding to the top inlet of the shot blasting machine 446 is formed on the side of the shielding rack 442. Fans 443 are evenly arranged on the side of the blanking rack 441, and the side of the fans 443 is fixedly connected to the inner side of the blanking rack 441. The side of the shot blasting machine 446 is fixedly connected to the bottom of the inner cavity of the shot blasting shell 41. The side of the collection box 445 is fixedly connected to the bottom of the inner cavity of the shot blasting shell 41. A baffle 444 is fixedly connected to the top of the collection box 445; When the steel shots and the shot slag continuously move downward in the discharge rack 4251, start the fan 443. The airflow generated by its operation will act on the mixture of steel shots and shot slag. Since the self-gravity of the steel shots is relatively large, they can continue to slide downward along the discharge rack 4251; while the shot slag with smaller density will be blown away by the airflow. This method of separation using airflow skillfully takes advantage of the difference in weight between the steel shots and the shot slag, realizes a non-contact and low-energy-consuming separation process, avoids the wear of the steel shots that may be caused by traditional mechanical separation, and effectively reduces the cost of steel shot loss.

[0014] On the side of the discharge rack 4251, the shielding rack 442 is provided with a notch corresponding to the top inlet of the shot blasting machine 446 on its side. The falling steel shots can enter the shot blasting machine directly through this notch to complete the collection, preparing for the next round of shot blasting work. Meanwhile, the shot slag blown away by the air flow moves towards the collection box 445 under the action of the wind. The suction mechanism arranged in the collection box 445 generates suction to guide the shot slag to enter the collection box 445 through the baffle 444. The suction mechanism and the fan 443 work together to form a complete air flow separation and collection system, which not only efficiently removes the shot slag from the working area, keeps the interior of the equipment clean, and reduces equipment failures caused by impurity accumulation, but also realizes the centralized recycling and treatment of the shot slag; Please refer to Figure 9 , the present invention provides a technical solution: a shot slag separation shot blasting process for steel shot rust removal, including the following steps: S1: Clamp the workpiece on the conveying rack 1 of the shot blasting machine; S2: The workpiece to be processed is sent into the working area of the shot blasting machine through the conveying rack 1. The impeller rotating at high speed inside the shot blasting component 4 accelerates the steel shots to a certain speed and then shoots them onto the surface of the workpiece, using the impact force of the steel shots to remove the rust layer, scale and other impurities on the surface of the workpiece to achieve the purpose of rust removal; S3: The steel shots shot onto the surface of the workpiece and impurities such as the knocked-off rust slag fall together and enter the recycling component 5 at the bottom of the connecting housing 2. The recycling component 5 is usually a funnel-shaped structure, which can collect the steel shots and impurities together for subsequent recycling treatment process; S4: The collected steel shots and impurities are lifted by the recycling component 5, and the steel shots and impurities are lifted from the recycling component 5 to the feeding position of the shot blasting component 4; S5: The lifted steel shots and impurities enter the shot blasting component 4. Due to the relatively large density of the steel shots, under the combined action of gravity and air flow, they will fall along a specific channel and re-enter the shot blasting machine 446; while the impurities such as rust slag have a relatively small density and will be carried by the air flow to other channels and enter the waste collection box 445, thus realizing the separation of the steel shots and the rust slag; S6: The separated clean steel shots enter the shot blasting machine 446 and participate in the shot blasting rust removal process of the workpiece in a cycle, realizing the multiple reuse of the steel shots and reducing the production cost.

[0015] Specific working process: Place the H-beam web on the conveying rack 1. Drive the H-beam web through the conveying rack 1 and enter the connecting housing 2 through the shielding curtain 3. Carry out rust removal work on the surface of the H-beam web through the shot blasting component 4. At the same time, the steel shots shot onto the surface of the workpiece and impurities such as the knocked-off rust slag fall together and enter the recycling component 5 at the bottom of the connecting housing 2. The steel shots are conveyed to the shot blasting component 4 through the recycling component 5 to carry out the shot slag separation work on the steel shots.

9. A shot slag separation shot blasting process for steel shot rust removal, according to the shot slag separation shot blasting equipment for steel shot rust removal as described in claim 1, characterized in that: The following steps are involved: S1: Clamp the workpiece on the conveyor frame (1) of the shot blasting machine; S2: The workpiece to be processed is transported into the working area of ​​the shot blasting machine through the conveyor frame (1). The high-speed rotating impeller inside the shot blasting component (4) accelerates the steel shot to a certain speed and then projects it onto the surface of the workpiece. The impact force of the steel shot removes the rust layer and oxide scale on the surface of the workpiece, thereby achieving the purpose of rust removal. S3: The steel shot projected onto the surface of the workpiece and the impurities such as rust residue that are knocked down fall together and enter the recovery component (5) located at the bottom of the connection shell (2). The recovery component (5) is usually a funnel-shaped structure that can collect the steel shot and impurities so as to enter the subsequent recycling process; S4: The collected steel shots and impurities are lifted by the recovery component (5), and the steel shots and impurities are lifted from the recovery component (5) to the feeding position of the shot peening component (4); S5: The lifted steel shot and impurities enter the shot blasting component (4). Due to their high density, the steel shot will fall along a specific channel under the combined effect of gravity and airflow and re-enter the shot blasting machine (446). However, impurities such as rust residues have a low density and will be carried by the airflow to other channels and enter the waste collection box (445), thereby achieving separation of the steel shot and rust residues. S6: The clean steel shots after separation enter the shot blasting machine (446) and cyclically participate in the shot blasting and rust removal process of the workpiece, thereby realizing multiple reuse of the steel shots and reducing production costs.
