[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1, such as Figure 1 and Figure 2 As shown in the figure, this utility model application provides a pellet recycling and processing device, such as... Figure 1 As shown, the system includes a processing tank 1, a sieve plate 11, a filter screen 12, a stirring assembly 13, and a water inlet device. The sieve plate 11 and the filter screen 12 are spaced apart within the processing tank 1, thus forming a material screening chamber 1a, a waste recovery chamber 1b, and a drainage chamber 1c sequentially from top to bottom within the processing tank 1. A discharge pipe 3 is provided on one side of the material screening chamber 1a, a waste outlet 4 is provided on one side of the waste recovery chamber 1b, and a drainage pipe 5 is provided on one side of the drainage chamber 1c. Control valves are installed on the discharge pipe 3, the waste outlet 4, and the drainage pipe 5. The water inlet device is connected to the processing tank 1 and is used to inject liquid into the processing tank 1. The stirring assembly 13 is used to stir the pellets within the material screening chamber 1a.

[0034] The sieve plate 11 has several sieve holes 111, the diameter of which is slightly smaller than the particle size of the shot. Since the shot itself gradually wears down or breaks during shot peening due to impact, the sieve plate 11 allows intact shot to be retained in the sieve chamber 1a. After cleaning, it is discharged through the discharge pipe 3 for recycling, thus ensuring the shot peening strengthening effect on the metal plate. Shot smaller than normal size or generated debris falls through the sieve holes 111 into the waste recovery chamber 1b for recycling. The liquid in the treatment tank 1 passes through the filter screen 12 into the drainage chamber 1c and is then discharged. The filter screen 12 has small mesh size, which can intercept debris and other impurities in the waste recovery chamber 1b, and finally discharge it through the waste outlet 4.

[0035] Optionally, the water inlet device includes an inlet pipe and a water pump installed on the inlet pipe, which draws liquid into the treatment tank 1. The inlet pipe is not shown in the diagram. Several nozzles may also be installed on the inlet pipe, and the water pump draws liquid into the inlet pipe and sprays it out through the nozzles.

[0036] Optionally, the stirring assembly 13 includes a second drive motor 131, a stirring rod 132, and stirring blades 133. The second drive motor 131 is installed at the bottom of the processing tank 1. The power output end of the second drive motor 131 is connected to one end of the stirring rod 132. The other end of the stirring rod 132 extends through the filter screen 12 and the sieve plate 11 into the screening chamber 1a. Stirring blades 133 are fixed to the outer wall of the stirring rod 132 located in the screening chamber 1a. The stirring assembly 13 helps to improve the cleaning effect of the pellets.

[0037] In one embodiment, a brush strip 14 is provided on the stirring rod 132 located in the waste recycling chamber 1b. The lower surface of the brush strip 14 is in contact with the upper surface of the filter screen 12, and the brush strip 14 can rotate synchronously during the rotation of the stirring rod 132. The brush strip 14 can prevent the filter screen 12 from being blocked, thus avoiding affecting drainage. Optionally, the brush strip 14 is fixedly connected to the outer wall of the stirring rod 132 by a bushing.

[0038] Optionally, the sieve plate 11 can be inclined downward toward the discharge pipe 3 to facilitate the discharge of the pellets from the discharge pipe 3.

[0039] Optionally, the filter screen 12 can be tilted downwards toward the drain pipe 5 to facilitate the discharge of debris intercepted by the filter screen 12.

[0040] In one embodiment, a fixed platform 15 is further included, located below the sieve plate 11. A sliding plate 16 is disposed within the cavity of the fixed platform 15. Several vertical rods 17 are disposed on the upper surface of the sliding plate 16, with positions corresponding to the sieve holes 111. Specifically, the positions of the vertical rods 17 correspond one-to-one with the sieve holes 111, and the diameter of the vertical rods 17 is smaller than the diameter of the sieve holes 111, allowing the vertical rods 17 to movably fit within the sieve holes 111. The vertical rods 17 slide in conjunction with the fixed platform 15, meaning that the fixed platform 15 has several through holes corresponding one-to-one with the sieve holes 111. Optionally, a sealing ring can be provided on the inner wall of the through holes to prevent liquid from entering the interior of the fixed platform 15. Optionally, an electric telescopic rod 18 is provided at the bottom of the slide plate 16. The movable end of the electric telescopic rod 18 is connected to the bottom of the slide plate 16. The slide plate 16 moves up or down under the drive of the electric telescopic rod 18, thereby driving the vertical rod 17 to move so that the vertical rod 17 can be placed in the screen hole 111, thereby cleaning the screen hole 111 and preventing debris from clogging the screen hole 111. In use, both the electric telescopic rod 18 and the second drive motor 131 can be started intermittently. Both the electric telescopic rod 18 and the second drive motor 131 are electrically connected to the control system and are intelligently controlled by the control system. When it is necessary to clear the screen holes 111 through the vertical rod 17, the second drive motor 131 is turned off and returns to the initial state. In the initial state, the vertical rods 17 on the slide plate 16 correspond one-to-one with the screen holes 111. At this time, the electric telescopic rod 18 is started, and the electric telescopic rod drives the vertical rods 17 to extend and retract back and forth to clear the screen holes 111. After clearing is completed, the electric telescopic rod 18 is turned off and returns to the initial state. In the initial state, the vertical rods 17 are located below the screen holes 111 and there is a gap between them and the screen holes 111.

[0041] Optionally, the fixed platform 15 can be connected to the stirring rod 132. Both the fixed platform 15 and the sliding plate 16 are connected to the outer wall of the stirring rod 132 via bushings. That is, both the fixed platform 15 and the sliding plate 16 have mounting holes, and bushings are installed in the mounting holes. The stirring rod 132 is rotatably or fixedly connected to the bushings. In one embodiment, the stirring rod 132 is fixedly connected to the bushing. During the rotation of the stirring rod 132, it can drive the fixed platform 15 and / or the vertical rod 17 protruding from the fixed platform 15 to rotate synchronously, which is beneficial to improving the filtration effect of the waste recycling chamber 1b. In another embodiment, the stirring rod 132 is rotatably connected to the bushing, and the fixed platform 15 and / or the vertical rod 17 may not rotate with the stirring rod 132.

[0042] In use, the treatment box 1 can be used in conjunction with a shot peening device. The shot peened by the shot peening device enters the treatment box 1 through the discharge port. The water inlet device can introduce acid or clean water into the treatment box 1. After cleaning, the drain pipe 5 is opened to discharge the wastewater. The shot in the screening chamber 1a is discharged through the discharge pipe 3, and the waste and debris in the waste recovery chamber 1b are discharged through the waste outlet 4 for recycling. The brush strip 14 ensures the filtration effect of the filter screen 12, and the vertical rod 17 intermittently enters the screen holes 111 to prevent the screen holes 111 from clogging, thus ensuring the screening effect of the screen plate 11.

[0043] Example 2: This invention provides a pellet recycling and processing device. Based on Example 1, the metal plate surface strengthening device further includes a drying box 2 connected to the screening chamber 1a. The drying box 2 is used to receive the pellets after cleaning and to dry them.

[0044] Specifically, the drying chamber 2 is equipped with a drying structure.

The drive component 23 is connected to the wire mesh frame 21 and can rotate under the drive of the drive component 23. In use, the pellets are placed inside the rotating wire mesh frame 21 for drying, which helps to improve the drying efficiency of the pellets.

[0045] Optionally, the top of the screen frame 21 is open, and the discharge pipe 3 is located above the screen frame 21. The pellets in the screening chamber 1a fall into the screen frame 21 through the discharge pipe 3.

[0046] Optionally, the heating assembly 22 includes a hot air blower 221, a drying plate 222, and nozzles 223. The hot air blower 221 can be installed on the upper part of the drying chamber or on the outside of the processing box 1 via the horizontal plate 20. The drying plate 222 is installed on the lower surface of the horizontal plate 20. The drying plate 222 is hollow, and multiple nozzles 223 are provided on its lower surface. The hot air blower 221 is connected to the inner cavity of the drying plate 222 through an air inlet pipe. When in use, the hot air blower 221 generates hot air, which is sent into the drying plate 222 through the air inlet pipe. The hot air is then sprayed out from the nozzles 223, thereby drying the pellets in the wire frame 21.

[0047] In one embodiment, the drive assembly 23 includes a third drive motor and a drive rod mounted on the power output end of the third drive motor. In this embodiment, the third drive motor is mounted on the bottom of the processing box 1, and the end of the drive rod away from the third drive motor is directly connected to the bottom of the mesh frame 21 for drive connection. The third drive motor drives the mesh frame 21 to rotate through the drive rod.

[0048] In one embodiment, the drive assembly 23 includes a third drive motor and a drive rod. In this embodiment, a collar 211 is provided on the outer wall of the mesh frame 21. One end of the drive rod is connected to the power output end of the third drive motor, and the other end extends to the outside of the collar 211. A drive ring is provided on the outer wall of the drive rod. The drive ring is drivenly connected to the collar 211. In use, the third drive motor drives the drive rod to rotate, and the drive rod drives the drive ring to rotate, thereby driving the collar 211 that meshes with it to rotate, thereby driving the mesh frame 21 to rotate.

[0049] In another embodiment, reference Figure 1 As shown, the drive assembly 23 includes a third drive motor 231, a drive rod 232, a rotating shaft 233, a drive wheel 234, and a driven wheel 235.

[0050] In this embodiment, the third drive motor 231 is mounted on the bottom of the processing box 1 via the mounting bracket 236. The third drive motor 231 is connected to the drive rod 232 via a rotating shaft 233, a drive wheel 234, and a driven wheel 235. Specifically, the power output end of the third drive motor 231 is connected to the rotating shaft 233. The drive wheel 234 is mounted on the outer wall of the rotating shaft 233, which is located between the bottom of the processing box 1 and the mounting bracket 236. Drive rods 232 are respectively provided on both sides of the drive wheel 234. The lower end of the drive rod 232 is rotatably connected to the mounting bracket 236 via a bearing. Both drive rods 232 are provided with driven wheels 235 that mesh with the drive wheel 234. The upper end of the drive rod 232 passes through the bottom wall of the processing box 1 and extends into the pellet drying chamber and is located outside the mesh frame 21. A collar 211 is provided on the outer wall of the mesh frame 21, and a drive ring 2321 that meshes with the collar 211 is provided on the outer wall of the drive rod 232. When in use, the third drive motor 231 is started, which drives the rotating shaft 233 to rotate. The driving wheel 234 drives the driven wheel 235 to rotate, and the driven wheel 235 drives the drive rod 232 to rotate. Thus, the drive rod 232 can drive the mesh frame 21 to rotate through the drive ring 2321 and the collar 211.

[0051] Optionally, one end of the rotating shaft 233 away from the third drive motor 231 extends into the pellet drying chamber and is located below the mesh frame 21. A fan 237 is installed on the rotating shaft 233 located in the pellet drying chamber. When in use, the rotating shaft drives the fan 237 to rotate, which helps to improve the uniformity of hot air in the pellet drying chamber and thus improve the drying effect.

[0052] In one embodiment, a plurality of third springs 212 are connected between the collar 211 and the outer wall of the mesh frame 21. The arrangement of the third springs 212 allows the mesh frame 21 to sway as it rotates with the collar 211, which helps to speed up the drying process.

[0053] In one embodiment, a stirring mechanism (not shown in the figure) may also be provided inside the mesh frame 21. The stirring mechanism stirs and turns the pellets inside the mesh frame 21, which can further improve the drying efficiency of the pellets.

[0054] In one embodiment, a conveying auger may be installed in the screening chamber 1a and / or the discharge pipe, through which the shot is fed into the screen frame 21. In another embodiment, a discharge pump may be installed on the discharge pipe 3, which draws the shot from the screening chamber 1a into the screen frame 21 for drying.

[0055] In use, the treatment box 1 can be used in conjunction with a shot peening device. The shot peening material sprayed by the shot peening device enters the treatment box 1 through the discharge port. The water inlet device can input acid or clean water into the treatment box 1. The second drive motor 131 works, driving the stirring blade 133 to stir the shot in the screening chamber 1a and drive the brush strip 14 to rotate on the upper surface of the filter screen 12. Shot, fragments, impurities, etc. with a particle size smaller than normal size fall into the waste recovery chamber 1b through the screen holes 111. After the second drive motor 131 works for a period of time, it is turned off. Then the electric telescopic rod 18 is started. The electric telescopic rod 18 drives the vertical rod 17 to extend and retract back and forth to clear the screen holes 111. After clearing, the electric telescopic rod 18 is closed and returns to the initial state. The second drive motor 131 continues to work. After the shot is cleaned for a certain period of time, the second drive motor 131 is turned off, and the control valve on the drain pipe 5 is opened to discharge the acid or clean water. If acid cleaning is used for the initial cleaning, after draining the acid, a second cleaning with clean water should be performed. The initial acid cleaning allows metal powder generated during processing to fall into the lower chamber and react with the acid, while the remaining shot or waste that does not react with the acid is washed away with water and recycled. After cleaning, the shot is discharged into drying chamber 2 for drying. After drying, the shot can be removed by opening the door of drying chamber 2 and added to the shot peening machine for reuse. Alternatively, a circulation pipe can be installed between drying chamber 2 and the shot peening machine, with a circulation pump installed on the pipe to pump the shot from drying chamber 2 into the shot peening machine.
