Description

Technical Field

[0001] This utility model relates to the field of steel grit treatment technology for shot blasting machines, and in particular to a device for separating and purifying steel grit and impurities in shot blasting machines. Background Technology

[0002] Shot blasting machines are casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. They can simultaneously remove sand, cores, and clean castings. Shot blasting machines are classified according to the structure of the casting support body, including drum type, chain plate type, rotary table type, trolley type, cage type, and hanging type. The shot used in shot blasting can include steel shot, cast iron shot, glass shot, ceramic shot, etc. Among these, steel shot is the most commonly used abrasive due to its high hardness and wear resistance. However, during shot blasting, steel shot of different particle sizes can be mixed with dust and impurities, directly affecting the recycling effect. Therefore, it is necessary to use a professional separation device to purify the waste steel shot to restore its performance and achieve steel shot particle size classification, meeting the differentiated needs of different workpieces for shot blasting processes.

[0003] Most existing shot blasting machine dust separation devices use a single dust extraction fan to treat the dust generated inside the device. Since some dust easily sticks to the surface of the shot, it affects the separation effect of the device.

[0004] The existing patent (publication number: CN212791804U) discloses a shot blasting machine sand and dust separation device. This utility model effectively improves the separation effect of the device on sand and dust by using a vibrating motor and a blower. At the same time, the separation components set up enable the device to screen the shot to a certain extent, thereby improving the use effect of the device. Moreover, the device has a simple structure and is easy to promote and use.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing shot blasting machine steel shot recycling and separation devices suffer from incomplete separation of impurities and dust from steel shot, resulting in poor quality of steel shot recycling. Furthermore, after completing the screening and cleaning of impurities and dust, they lack the ability to classify and recycle steel shot of different particle sizes, failing to meet the differentiated needs of different workpiece materials such as aluminum alloys and steel for refined shot blasting processes.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A shot blasting machine steel shot and impurity separation and purification device includes four support legs 1, and a separation mechanism 2 is provided on the top of the support legs 1;

[0030] The separation mechanism 2 includes a screening component 21 located on top of the support leg 1. Telescopic spring columns 22 are welded to the four corners of the top of the screening component 21. A separation box 23 is welded to the top of the telescopic spring columns 22. A vibration motor 24 is bolted to the bottom of the separation box 23. The vibration motor 24 is externally controlled by a controller. A feed pipe 25 is connected to the top of the separation box 23. A rotating brush structure 26 is located inside the separation box 23 at the bottom of the feed pipe 25. A dust collection structure 27 is located on the top side inside the separation box 23. A separation filter 28 is located in the middle inside the separation box 23 at the bottom of the rotating brush structure 26. A waste removal plate 29 is connected to the right side of the separation box 23, located to the right of the separation filter 28.

[0031] In this embodiment: By setting the separation mechanism 2, the steel shot after shot blasting enters the separation box 23 through the feed pipe 25. The activated rotating brush structure 26 rotates and disperses the steel shot, effectively removing impurities and dust adhering to its surface. At the same time, the vibration motor 24 on the bottom side of the separation box 23 generates high-frequency vibration under the control of the controller. This, together with the telescopic spring columns 22 at the four corners of the top of the screening component 21, assists the vibration of the separation box 23, causing the separation filter screen 28 to vibrate synchronously at high frequency, enhancing the interception and filtration efficiency of solid impurities. Meanwhile, the suction on the top side of the separation box 23... The dust structure 27 simultaneously absorbs suspended fine dust. During the separation process, the detached solid impurities slide to the right along the inclined separation filter screen 28 and are discharged from the separation box 23 via the impurity discharge plate 29. The pure steel shot falls through the separation filter screen 28 into the screening component 21 below. The screening component 21 rotates and screens the steel shot, classifying it into coarse sand, standard sand, and fine sand according to particle size and discharging and collecting them separately. This achieves efficient separation and fine classification of steel shot and impurities, significantly improving the quality of steel shot recycling and meeting the differentiated needs of shot blasting processes for different workpiece materials.

[0032] Specifically, such as Figure 5 As shown, the screening assembly 21 includes a screening box 211 welded to the top of the support leg 1. The top of the screening box 211 is welded to the bottom of the telescopic spring column 22. An elastic folded hose 212 is connected to the left side of the top of the screening box 211. The top of the elastic folded hose 212 is connected to the left side of the bottom of the separation box 23.

[0033] Specifically, such as Figure 5 As shown, a guide cylinder 213 is provided on the left side of the screening box 211, and a screening motor 214 is bolted to the right side of the screening box 211. The screening motor 214 is externally controlled by a controller. The output end of the screening motor 214 passes through the right side of the screening box 211. A screening cylinder 215 is rotatably connected inside the screening box 211. The right side of the screening cylinder 215 is fixedly connected to the output end of the screening motor 214. The left side of the screening cylinder 215 is connected to the right side of the guide cylinder 213. The surface of the screening cylinder 215 has screen holes 216 with a diameter of 1.5mm, a gradually changing diameter of 1.5-3mm, and a diameter of 3mm sequentially opened along the axial direction from the feed end to the discharge end, forming a graded layout of fine sand separation zone, standard sand separation zone, and coarse sand separation zone, so as to achieve precise screening of steel sand particle size.

[0034] Specifically, such as Figure 5 As shown, a spiral guide rib 217 is welded inside the screening cylinder 215, and a recovery discharge hopper 218 is connected to the bottom of the screening box 211 from left to right along the axial direction. The recovery discharge hopper 218 is located directly below each screen hole 216 of the screening cylinder 215 to achieve precise collection of steel sand of different particle sizes.

[0035] In this embodiment: by setting up a screening component 21, the pure steel sand in the separation box 23 enters the guide cylinder 213 on the left side of the screening box 211 through the elastic folded hose 212. Under the action of gravity, it is guided into the rotating screening cylinder 215. The screening motor 214 drives the screening cylinder 215 to rotate. The spiral guide ribs 217 on its inner wall push the steel sand to move towards the discharge end. During the process, the steel sand passes through the 1.5mm screen hole 216 in sequence, so that the fine sand falls into the first recovery discharge hopper 218. Then it passes through the 1.5-3mm gradient screen hole 216, so that the standard sand falls into the middle recovery discharge hopper 218. Finally, it passes through the 3mm screen hole 216, so that the coarse sand falls into the last recovery discharge hopper 218. This achieves three-level precise grading, ensuring efficient separation and collection of steel sand of different particle sizes, and meeting the requirements of fine shot blasting.

[0036] Specifically, such as Figure 3 As shown, the rotating brush structure 26 includes a servo motor 261 bolted to the rear side of the separation box 23. The output end of the servo motor 261 passes through the rear side of the separation box 23, and the servo motor 261 is connected to an external controller for signal control.

[0037] Specifically, such as Figure 3 As shown, rollers 262 are rotatably connected to both sides of the rear side inside the separation box 23. The rear side of the rollers 262 is fixedly connected to the output end of the servo motor 261, and a separation brush 263 is fixedly connected to the outer side of the rollers 262.

[0038] In this embodiment: by setting a rotating brush structure 26, the servo motor 261 drives the roller 262 to rotate, which drives the outer separating brush 263 to rotate synchronously. When the steel sand falls from the feed pipe 25 into the separation box 23, the rotating separating brush 263 breaks it up and flips it, so that the impurities and dust adhering to the surface of the steel sand are completely removed, creating conditions for the subsequent interception by the separating filter screen 28 and the absorption by the dust suction structure 27, effectively improving the steel sand purification effect.

[0039] Specifically, such as Figure 3 As shown, the suction structure 27 includes a dust filter box 271 bolted to the right side of the separation box 23. The bottom of the dust filter box 271 is connected to a suction pipe 272, the bottom of the suction pipe 272 penetrates the top of the separation box 23, and the bottom of the suction pipe 272 is connected to a suction hopper 273. The suction hopper 273 is located to the right of the separation brush 263 and is located on top of the separation filter 28.

[0040] Specifically, such as Figure 3 As shown, a vacuum cleaner 274 is bolted to the right side of the separation box 23. The vacuum cleaner 274 is controlled by an external controller. The suction end of the vacuum cleaner 274 is connected to a duct 275. The left side of the duct 275 is connected to the right side of the dust filter box 271.

[0041] In this embodiment: by setting up a dust collection structure 27, after the dust collection fan 274 is started, a negative pressure airflow is formed in the dust filter box 271, duct 275, suction pipe 272 and dust collection bucket 273. The dust generated when the separation brush 263 disperses the steel shot is sucked into the dust collection bucket 273 under the action of the airflow, enters the dust filter box 271 through the suction pipe 272 for filtration, and the purified air is discharged by the dust collection fan 274, realizing efficient dust collection, avoiding secondary pollution, and ensuring a safe working environment.

[0042] Working Principle: In the process of using the steel shot and impurity separation and purification device in a shot blasting machine, the steel shot to be processed first enters the separation box 23 through the feed pipe 25 at the top of the separation box 23. At this time, the external controller controls the servo motor 261 on the back of the separation box 23 to drive the roller 262 to rotate, which in turn drives the outer separation brush 263 to rotate, breaking up and turning the steel shot, removing the impurities and dust adhering to its surface. At the same time, the vibration motor 24 on the bottom of the separation box 23 generates high-frequency vibration under the control of the controller. In conjunction with the telescopic spring columns 22 at the four corners of the top of the screening box 211, the separation box 23 and the separation filter screen 28 vibrate synchronously, enhancing the interception effect of solid impurities. The separated solid impurities slide to the right along the inclined separation filter screen 28 and are discharged through the impurity discharge plate 29, while the suspended fine dust is absorbed by the dust collection hopper 273 on the top side of the separation box 23. Specifically, after the dust collection fan 274 is started, a negative pressure airflow is formed, which is then drawn by the dust collection fan. Dust is drawn into the dust filter box 271 by the bucket 273 and suction pipe 272. The purified air is discharged by the dust extraction fan 274 through the duct 275. The pure steel shot, after impurity separation, passes through the separation filter screen 28 and falls into the guide cylinder 213 on the left side of the screening box 211 through the elastic folded hose 212 (which is made of wear-resistant elastic rubber and has built-in reinforcing ribs). It then enters the screening cylinder 215. The screening motor 214 drives the screening cylinder 215 to rotate. The spiral guide ribs 217 on its inner wall push the steel shot towards the discharge end. The steel shot passes through the sieve holes 216 on the surface of the screening cylinder 215 with a diameter of 1.5mm, a gradual diameter of 1.5-3mm, and a diameter of 3mm. The steel shot of the corresponding particle size falls into the recycling discharge buckets 218 arranged from left to right at the bottom of the screening box 211. This achieves precise classification and collection of fine sand, standard sand, and coarse sand. The entire set of components works together to efficiently complete the purification and particle size classification of steel shot, meeting the fine shot blasting requirements of different workpieces.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
