[0002] Stainless steel shot blasting equipment is a specialized device for surface treatment of stainless steel parts, aluminum alloy die castings, copper alloy parts, etc. It uses a high-speed rotating shot blasting wheel to propel stainless steel shot at a high speed and a certain angle onto the workpiece surface. The impact and friction of the stainless steel shot removes impurities such as oxide scale, rust, paint, and dirt from the workpiece surface. At the same time, it can also form a uniform roughness on the workpiece surface, improving the adhesion of the coating and the fatigue life of the workpiece.

[0003] Currently, most shot blasting equipment does not recycle stainless steel shot after shot blasting. The stainless steel shot mixes with waste after shot blasting, making it difficult to collect effectively. During the recycling process, the stainless steel shot cannot be effectively separated from impurities such as oxide scale and rust particles, resulting in low purity of the recycled stainless steel shot and affecting its reuse.

[0021] 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.

[0022] Please see Figures 1 to 5 As shown, this utility model embodiment provides a multi-functional shot blasting device for stainless steel shot, including a processing box 1. A shot blasting device is installed inside the processing box 1. A support frame 2 is fixed to the bottom of the processing box 1. A through groove is opened at the bottom of the processing box 1, through which the stainless steel shot sprayed from inside the processing box 1 is discharged. A movable frame 3 is arranged at the top inside the support frame 2. A filter screen 4 is embedded in the bottom of the inner wall of the movable frame 3. The diameter of the stainless steel shot is larger than the aperture of the filter screen 4. A vibration structure 5 is provided on the surface of the movable frame 3. A feeding hopper 6 is fixed to the left side of the moving frame 3. The feeding hopper 6 is inclined. A collecting hopper 7 is fixed to the lower part of the inner wall of the support frame 2. A collecting plate 8 is slidably connected to the bottom of the collecting hopper 7. A fixing plate 9 is fixed to the lower left side of the support frame 2. A processing box 10 is placed on the front side of the top of the fixing plate 9. The interior of the processing box 10 is filled with an acidic solution (in this embodiment, nitric acid with a concentration of 8%-10% is used to remove the oxide scale and rust on the surface of the stainless steel shot). A shaking structure 11 is fixed to the rear side of the top of the fixing plate 9.

[0023] Please see Figures 1 to 5As shown, the vibration structure 5 includes a mounting platform 51, a vibration motor 52, and a spring 53. The mounting platform 51 is fixed to the right side of the movable frame 3, the vibration motor 52 is fixed to the top of the mounting platform 51, and the spring 53 is fixed to the front and rear sides of the lower left side of the movable frame 3 and the front and rear sides below the mounting platform 51. The other end of the spring 53 is fixedly connected to the surface of the support frame 2. When the vibration motor 52 is turned on, the vibration motor 52 causes the movable frame 3 to vibrate as a whole through the mounting platform 51. When the stainless steel shot falls above the filter screen 4, the vibration allows the stainless steel shot to be quickly separated from the oxide scale and rust particles. The stainless steel shot remains above the filter screen 4, while the oxide scale and rust particles fall into the collection hopper 7 below and onto the collection plate 8.

[0024] Please see Figures 1 to 5 As shown, the movable frame 3 is inclined. A baffle plate 12 is slidably connected to the left side of the inner wall of the movable frame 3. Electric push rods 13 are fixed to the left side of both the front and rear sides of the movable frame 3. A fixing plate 14 is fixed to the top of the output shaft of the electric push rod 13. The fixing plate 14 is fixedly connected to the baffle plate 12. When stainless steel shot falls above the filter screen 4, the baffle plate 12 will block the stainless steel shot sliding to the left. After the stainless steel shot is effectively separated from the oxide scale and rust particles, the electric push rod 13 will open, and the output shaft of the electric push rod 13 will push the fixing plate 14 to rise, thereby causing the baffle plate 12 to move upward, so that the stainless steel shot on the surface of the filter screen 4 can enter the processing box 10 below for subsequent pickling and separation operations.

[0025] Please see Figures 1 to 5As shown, the swaying structure 11 includes a drive motor 111, a rotating disk 112, a push-pull rod 113, and a connecting block 114. The drive motor 111 is fixed to the rear side of the top of the fixed plate 9, the rotating disk 112 is fixed to the top of the output shaft of the drive motor 111, the push-pull rod 113 is rotatably connected to the front side of the top of the rotating disk 112, and the connecting block 114 is fixed to the top of the back of the processing box 10. The front side of the push-pull rod 113 is hinged to the connecting block 114. Guide grooves 15 are provided on both the left and right sides of the top of the fixed plate 9, and guide strips 16 are fixed on both the left and right sides of the bottom of the processing box 10. The guide strips 16 are located inside the guide grooves 15 and are slidably connected to the inner wall of the guide grooves 15. After the drive motor 111 is turned on, the output shaft of the drive motor 111 drives the upper rotating disk 112 to rotate, which in turn causes the push-pull rod 113 on the surface of the rotating disk 112 to move. As the rotating disk 112 rotates continuously, the push-pull rod 113 pushes the front processing box 10 to swing back and forth through the connecting block 114, so that the stainless steel shot can fully contact the acid solution, avoid local low concentration or accumulation of reaction products, accelerate the dissolution and removal of oxide scale and rust, and improve pickling efficiency. A guide plate 17 is fixed on the top of the processing box 10. The guide plate 17 is located on the front side of the top of the processing box 10. The guide plate 17 is inclined. When the stainless steel shot slides down from the feed hopper 6, it is guided by the guide plate 17 so that the stainless steel shot falls into the processing box 10 for pickling.

[0026] When the shot blasting device performs shot blasting on the workpiece, the stainless steel shot inside the processing box 1 comes into contact with the workpiece and falls through the through groove at the bottom of the processing box 1 onto the surface of the filter screen 4 inside the movable frame 3. At this time, the operator can turn on the vibration motor 52, which causes the entire movable frame 3 to vibrate, separating the stainless steel shot from the oxide scale and rust particles, removing impurities in advance. Then, the operator opens the electric push rod 13, which pushes the baffle plate 12 upward, and the stainless steel shot on the surface of the filter screen 4 falls into the inside of the feed hopper 6, and finally into the treatment box 10 to come into contact with the acid solution. Acid washing can thoroughly remove the residual oxide scale and rust on the surface of the stainless steel shot. The operator then turns on the drive motor 111 at the rear, which causes the push rod 113 to push the treatment box 10 back and forth to enhance the cleaning effect, making the surface of the stainless steel shot cleaner and restoring it to its original condition. Then, the operator can take out the double-treated stainless steel shot and rinse it with clean water before it can be reused, thus completing the recycling of the stainless steel shot.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
