Description

Technical Field

[0001] The present application relates to the technical field of shot blasting machines, and in particular to a cleaning device for a shot blasting machine. Background Art

[0002] A shot blasting machine uses a high-speed rotating impeller to throw projectiles (such as steel and aluminum shots) onto the surface of a workpiece to remove impurities such as sand, scale, rust, and coatings. It is widely used in industries such as casting, forging, welding, machinery manufacturing, construction machinery, mining machinery, pressure vessels, automobiles, and ships.

[0003] To prevent the shot blasting machine from being attracted by the magnetic components inside the machine and to ensure a smooth cleaning process, shot blasting with materials that are not affected by magnets is typically used. This avoids the problems that magnetic shot can cause, such as incomplete cleaning or residue on the workpiece surface. Therefore, the available shot materials include stainless steel shot, glass beads, ceramic shot, and aluminum shot.

[0004] The production cost of these abrasives is high. To effectively recycle resources and reduce production costs, the abrasives after shot blasting are often recycled and reused. However, these abrasives are often mixed with large amounts of iron filings, dust, and other waste, requiring effective separation and cleaning before reuse. Failure to do so can affect the quality and efficiency of subsequent processing and increase production costs. Furthermore, inadequate abrasive cleaning can lead to environmental pollution.

[0005] A Chinese patent with announcement number CN210081507U discloses a cleaning device for a shot blasting machine, including a box body, a feed hopper is provided on the top of the box body, a through hole is provided in the middle of one side of the box body, a holder is fixedly connected to one side of the box body close to the through hole, a motor located above the through hole is fixedly connected to one side of the box body, a fixed block is fixedly connected to the inner wall of the top of the box body, a slide is provided at the bottom of the fixed block, a slider is movably connected to the inside of the slide, a movable rod is fixedly connected to the bottom of the slider, and the bottom end of the movable rod is fixedly connected to the shell.

[0006] In the process of recycling and cleaning the shot materials after shot blasting, the above-mentioned cleaning device only performs multi-stage vibration screening on the shot material mixture mixed with a large amount of iron filings, dust and other waste according to the particle size. The dust and iron filings attached to the shot materials are difficult to be effectively separated by vibration screening alone. Therefore, the shot materials carrying dust and iron filings are not cleaned in place, which easily causes secondary pollution, thereby reducing the reuse efficiency of the shot sand; and then they are directly put into the shot blasting cleaning machine for reuse, which will have a great impact on the working efficiency of the shot blasting machine. Utility Model Content

[0007] In order to improve the recycling efficiency of shot materials after shot blasting, the present application provides a cleaning device for a shot blasting machine.

[0008] The cleaning device of a shot blasting machine provided in this application adopts the following technical solution:

[0009] A cleaning device for a shot blasting machine comprises a box body, wherein two chambers are vertically distributed along the inner edge of the box body, a material guide port is opened between the two chambers, and a box door is hingedly provided on the box body corresponding to each chamber, the top of the box body is connected to the upper chamber and a feed hopper is provided, an electromagnetic plate is provided in the upper chamber, and one electromagnetic plate is provided on both sides of the feed hopper in the blanking direction, a sieve plate and a filter frame are provided in the lower chamber, the sieve plate is located directly below the material guide port, and the filter frame is located below the sieve plate, a vibration component for driving the sieve plate to vibrate, and a cleaning component for spraying clean water into the filter frame are provided on the box body, and a water outlet for discharging sewage after cleaning the shot material is provided on the bottom wall of the box body.

[0010] By implementing the above technical solution, the cleaning device of a shot blasting machine effectively separates iron chips from the shot and removes dust. First, an electromagnetic plate, located in the upper chamber, attracts iron chips from the shot falling from the feed hopper, ensuring initial separation. The shot then passes through the feed inlet and falls onto the sieve plate in the lower chamber. The vibrations of the vibrating assembly effectively separate the shot from large waste particles. After being filtered by the sieve plate, the shot falls through the gaps in the sieve plate and into the filter frame below. The cleaning assembly sprays clean water into the filter frame, thoroughly cleaning the dust adhering to the shot. Finally, the cleaned wastewater is discharged through the outlet. The operator can then open the door of the lower chamber, remove the cleaned shot, and re-enter the shot blast machine for cleaning. This deep cleaning by the cleaning device improves the reuse efficiency of the shot and reduces contamination during subsequent processing.

[0011] Optionally, the vibration assembly includes rollers arranged parallel to each other on both sides of the sieve plate, cam rollers mounted on the rollers, and a reciprocating motor for driving the rollers to rotate. The sieve plate is provided with a connecting ear plate on the frame parallel to the axial direction of the roller, and the connecting ear plate is hingedly arranged between the tip side wall of the cam roller away from the rotating shaft.

[0012] By adopting the above technical solution, the reciprocating motor is activated to cause the roller to begin to oscillate back and forth. The oscillation of the roller drives the cam roller to oscillate synchronously, thereby causing the screen plate to shake both vertically and horizontally. By adjusting the reciprocating rotation frequency of the reciprocating motor, the vibration frequency of the screen plate can be adjusted, thereby ensuring that the pellets move smoothly on the screen plate while effectively separating debris. The possibility of screen plate blockage when screening pellets and large particles of waste is reduced, thereby further improving screening efficiency and pellet cleanliness.

[0013] Optionally, the two rollers are rotatably arranged on the box body, and their ends extend out of the box body. Synchronous wheels are sleeved on the ends of the two rollers extending out of the box body, and a synchronous belt is sleeved between the two synchronous wheels. The output shaft of the reciprocating motor is sleeved with a driving wheel that is meshed with the synchronous belt.

[0014] By adopting the above technical solution and utilizing the synergistic effect of the synchronous wheel and the synchronous belt, the screen plate is ensured to maintain uniform vibration during operation, which effectively improves the separation efficiency of impurities in the shot material and thereby improves the reuse efficiency of the shot material.

[0015] Optionally, a water storage tank is provided on one side of the box body, and the cleaning assembly includes a water distribution pipe located at the bottom of the screen plate and arranged on the inner wall of the box body, and cleaning nozzles are evenly distributed on the water distribution pipe and directed towards the filter frame. The water inlet end of the water distribution pipe is connected between the side wall of the box body and the water storage tank, and a water outlet pump is provided on the water storage tank, and the water outlet pump is arranged in series on the water distribution pipe.

[0016] By adopting the above technical solution, the clean water in the water tank is pressurized by the water outlet pump and transported to the cleaning nozzle through the water distribution pipe. The cleaning nozzle sprays clean water toward the filter frame, effectively cleaning the shot in the filter frame, removing dust and iron filings on the surface of the shot, and improving the reuse efficiency of the shot.

[0017] Optionally, a water pump is connected between the water outlet and the top wall of the water tank, a water pump is provided between the box body and the water tank, and the water pump is connected in series to the water pump.

[0018] By adopting the above technical solution, the wastewater after cleaning is recovered through the pumping pipe between the water outlet and the top wall of the water storage tank, and the wastewater is pumped back into the water storage tank by the water pump, thus realizing the recycling of cleaning water, effectively saving water resources and reducing production costs. At the same time, the provision of the water pump ensures the smooth recovery of wastewater, improving the practicality of the device.

[0019] Optionally, a filter element is provided in the water tank below the water outlet end of the water pumping pipe, the water distribution pipe extends to a position in the water tank below the filter element, and the water inlet end of the water distribution pipe extends to the inner bottom wall of the water tank.

[0020] By adopting the above technical solution, the filter element in the water tank can effectively remove impurities in the circulating water, ensuring the cleanliness of the water sprayed into the filter frame, thereby improving the shot cleaning effect and reducing the risk of clogging; at the same time, the water inlet end of the water distribution pipe extends to the inner bottom wall of the water tank, which helps to make full use of the water resources in the water tank, ensure a continuous and stable water supply to the cleaning components, and improve the cleaning quality and efficiency of the shot.

[0021] Optionally, a visual window is vertically provided on the side wall of the water tank, a scale is vertically provided on the visual window, and a water supply pipe is provided on the top wall of the water tank on one side of the water suction pipe and connected to the inner cavity.

[0022] By adopting the above technical solution, the visual window and scale arranged on the side wall of the water tank facilitate intuitive observation of the water level changes in the water tank, ensuring the normal operation of the cleaning component. At the same time, the water supply pipe on the top wall of the water tank facilitates timely replenishment of cleaning water, ensuring the water consumption during the shot cleaning process, thereby improving the cleaning effect and reuse efficiency of the shot.

[0023] Optionally, an exhaust fan is provided on the outer wall of the box body, and the exhaust fan is located on one side of the filter frame, and the exhaust fan is connected to the chamber below.

[0024] By adopting the above technical solution, the exhaust fan can accelerate the air flow around the filter frame, accelerating the evaporation of moisture from the surface of the cleaned pellets. This keeps the cleaned pellets dry and allows operators to directly remove the pellets from the filter frame for reuse. This not only improves the reuse efficiency of the pellets, but also further reduces pollution problems in subsequent processing.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The cleaning device of the shot blasting machine can effectively separate the iron chips in the shot and clean the dust. First, the electromagnetic plate is set in the upper chamber, which can absorb the iron chips in the shot falling from the feed hopper to ensure the initial separation of the iron chips in the shot. Then, the shot falls onto the sieve plate in the lower chamber through the material guide port. The vibration of the vibration component can effectively separate the shot and large-particle waste. After screening by the sieve plate, the shot falls into the filter frame below from the gap of the sieve plate. The cleaning component sprays clean water into the filter frame to thoroughly clean the dust attached to the shot. Finally, the cleaned sewage is discharged through the outlet. At this time, the operator can open the door of the lower chamber and take out the cleaned shot to put it into the shot blasting machine again for cleaning operations. The deep cleaning of the cleaning device improves the reuse efficiency of the shot and reduces pollution problems in subsequent processing;

[0027] 2. Start the reciprocating motor to make the roller start to swing back and forth. The swing of the roller drives the cam roller to swing synchronously, thereby driving the screen plate to shake in both vertical and horizontal directions. By adjusting the reciprocating rotation frequency of the reciprocating motor, the vibration frequency of the screen plate can be adjusted, thereby ensuring that the pills move smoothly on the screen plate while effectively separating debris. The possibility of the screen plate being blocked when screening pills and large particles of waste is reduced, thereby further improving the screening efficiency and the cleanliness of the pills;

[0028] 3. The synergistic effect of the synchronous wheel and the synchronous belt is used to ensure that the screen plate maintains uniform vibration during the working process, which effectively improves the separation efficiency of impurities in the shot material and thus improves the reuse efficiency of the shot material.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1-4 This application is described in further detail.

[0036] An embodiment of the present application discloses a cleaning device for a shot blasting machine.

[0037] Reference Figure 1 and Figure 2A cleaning device for a shot blasting machine includes a box body 1, with two chambers vertically distributed along the inner edge of the box body 1, and a bucket-shaped material guide port 11 is provided between the two chambers. A door 12 is hingedly provided on the box body 1 corresponding to each chamber. A feed hopper 13 is fixedly provided on the top of the box body 1, which is connected to the upper chamber. An electromagnetic plate 2 is installed in the upper chamber, and one electromagnetic plate 2 is provided on both sides of the feed hopper 13 in the direction of material drop. A sieve plate 3 is installed in the lower chamber just below the material guide port 11, and a vibration assembly 4 is provided on the box body 1; a filter screen frame 5 is installed below the sieve plate 3, a water tank 6 is fixedly provided on one side of the box body 1, a cleaning assembly 7 connected to the water tank 6 is provided on the box body 1, and a water outlet 14 is provided on the bottom wall of the box body 1. An exhaust fan 8 is fixedly provided on the outer wall of the box body 1, and the exhaust fan 8 is located on one side of the filter screen frame 5 and is connected to the lower chamber.

[0038] Reference Figure 1 and Figure 2 After shot blasting, the pellets fall from the feed hopper 13, first falling through the upper chamber. As they pass through the electromagnetic plate 2, the iron filings produced by the shot blasting workpiece are attracted by the electromagnetic plate 2 and separated from the falling pellet mixture. The pellet mixture then continues to fall through the guide port 11 onto the sieve plate 3 in the lower chamber. Vibration by the vibrating assembly 4 removes large particles of waste material from the sieve plate 3, while the pellets fall through the gaps in the sieve plate 3 into the filter frame 5 below. Under the flushing of the cleaning assembly 7, dust attached to the pellets is washed away and flows from the filter frame 5 to the bottom of the housing 1, where it flows out through the water outlet 14. The exhaust fan 8 is then activated, accelerating the air flow around the filter frame 5, causing the moisture on the surface of the cleaned pellets to evaporate faster, thus keeping the cleaned pellets dry. The operator can then remove the cleaned pellets by opening the chamber door 12.

[0039] Reference Figure 2 and Figure 3 The vibration assembly 4 includes a roller 41, a cam roller 42, and a reciprocating motor 43. One roller 41 is rotatably mounted on each side of the sieve plate 3, and the two rollers 41 are arranged parallel to the length of the housing 1. The cam rollers 42 are fixedly mounted on the rollers 41. Each roller 41 is rotatably mounted on the housing 1, and its end rotates through the side wall of the housing 1 and extends out of the housing 1. A synchronous pulley 411 is fixedly mounted on the end of the roller 41 extending out of the housing 1. A synchronous belt 4111 is mounted between the two synchronous pulleys 411. The reciprocating motor 43 is fixedly mounted on the outer wall of the housing 1. A driving pulley 431 that meshes with the synchronous belt 4111 is fixedly mounted on its output shaft. A connecting lug 31 is fixedly mounted on the frame of the sieve plate 3 parallel to the axis of the rollers 41. The connecting lug 31 rotates in conjunction with the adjacent cam roller 42 and is hingedly mounted on the tip side wall of the cam roller 42 away from the rotating shaft.

[0040] Reference Figure 1 and Figure 2 The cleaning assembly 7 includes a water distribution pipe 71 and a cleaning nozzle 72. The fixing ring of the water distribution pipe 71 is arranged on the inner wall of the box body 1 and is located below the sieve plate 3 in the lower chamber of the box body 1. The cleaning nozzles 72 are connected to the water distribution pipe 71 and are installed on the water distribution pipe 71 at equal intervals. The water inlet end of the water distribution pipe 71 is passed through the side wall of the box body 1 and is connected to the water storage tank 6. A water outlet pump 61 is fixedly provided on the water storage tank 6, and the water outlet pump 61 is arranged in series on the water distribution pipe 71. A water pumping pipe 141 is fixedly provided between the water outlet 14 and the top wall of the water storage tank 6. A water pumping pump 9 is fixedly provided between the box body 1 and the water storage tank 6, and the water pump 9 is connected in series on the water pumping pipe 141.

[0041] Reference Figure 1 and Figure 4 A filter element 62 is fixedly installed in the water tank 6, below the outlet end of the water extraction pipe 141. A water distribution pipe 71 extends into the water tank 6 and passes through the water tank 6, below the filter element 62. The water inlet end of the water distribution pipe 71 extends to the inner bottom wall of the water tank 6. A viewing window 63 is fixedly installed vertically on the side wall of the water tank 6, with a scale 631 electroplated vertically on the upper edge of the viewing window 63. A water supply pipe 64 is fixedly installed on the top wall of the water tank 6, on one side of the water extraction pipe 141, and connected to the inner cavity.

[0042] The cleaning device of a shot blasting machine according to the embodiment of the present application is implemented as follows: the shot material after shot blasting falls from the feed hopper 13, first falls through the upper chamber, and in the process of passing through the electromagnetic plate 2, the iron filings generated by the shot blasting workpiece are attracted by the electromagnetic plate 2 due to the magnetic attraction of the electromagnetic plate 2, leaving the falling shot material mixture; at this time, the shot material mixture continues to fall and falls onto the sieve plate 3 in the lower chamber through the material guide port 11. As the reciprocating motor 43 drives the cam roller 42 to rotate back and forth, the sieve plate 3 begins to vibrate, so that large particles of waste remain on the sieve plate 3, while the shot material falls into the filter frame 5 below from the gaps in the sieve plate 3. Under the flushing of the cleaning nozzle 72, the dust attached to the shot material flows from the filter frame 5 to the bottom of the box body 1 after being flushed, and flows out from the water outlet 14. The sewage is drawn into the water storage tank 6 by the water pump 9 and filtered by the filter element 62, and then used reciprocatingly. Then the exhaust fan 8 is started to accelerate the air flow around the filter frame 5, so that the water on the surface of the cleaned pellets is accelerated to evaporate, so that the pellets finally cleaned are kept dry. After the operator opens the box door 12, the cleaned pellets can be taken out.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
