Description

Technical Field

[0001] This utility model relates to the field of shot blasting technology, and more specifically, to a shot blasting device for treating metal workpieces after shot blasting. Background Technology

[0002] A shot blasting machine is a device that uses a large number of small-diameter steel shot to impact and rub against the outer surface of a workpiece to clean the surface of the workpiece and remove dirt such as slurry. While cleaning the surface of the workpiece, the metal steel shot in the shot blasting machine also gives the surface a certain roughness. The shot blasting machine needs to continuously recover the steel shot for continued use. However, during the recovery of the steel shot, a large number of metal fragments and oil impurities will be mixed in. Direct use will affect the shot blasting effect, so a processing device is needed to clean the shot after shot blasting.

[0003] Existing shot blasting equipment has a relatively limited cleaning effect. Some use screens to sieve the shot, but this is not very effective at removing impurities adhering to the shot. Others soak or spray the shot, but this method requires the shot to be processed in batches, resulting in a long cleaning cycle that cannot meet the needs of continuous shot blasting production lines. Furthermore, shot washed with water is prone to retaining moisture and impurities, affecting the quality of subsequent shot blasting. Utility Model Content

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-6 As shown, a shot blasting post-shot material processing device for metal workpieces includes: a separation box 1, the interior of which is divided into a waste liquid chamber 2 and a shot material chamber 3 by a partition; a control frame 4 is fixedly connected to the upper surface of the separation box 1; a processing tank 5 is rotatably connected inside the control frame 4; and a feed hopper 6 is installed on the top of the control frame 4. Cleaning section 7 is disposed inside the processing tank 5 and connected to the feed hopper 6, and is used to clean multiple batches of pellets simultaneously. A drive unit 8 is fixed to the control frame 4 and the processing tank 5, and is used to control the processing tank 5 to rotate. Liquid supply unit 9, which is installed on the top of the separation tank 1, is used to input cleaning liquid into the cleaning unit 7; Separation section 10 is disposed inside the separation box 1 and positioned directly below the cleaning section 7, for separating the cleaned pellets from the wastewater; The conveying unit 11 is fixed outside the separation box 1 and its bottom is connected to the separation box 1 for conveying and drying the pellets; During operation, the shot blasted material is fed into the feed hopper 6, and the liquid supply unit 9 simultaneously inputs heated cleaning liquid into the feed hopper 6. Simultaneously, under the control of the drive unit 8, the processing tank 5 rotates intermittently, causing the feed pipes 13 on the cleaning cylinders 12 to align sequentially with the feed hopper 6. This allows the shot and cleaning liquid to be fed into the cleaning cylinders 12 through the feed pipes 13, enabling simultaneous loading of multiple batches. This allows the cleaning cylinders 12 to perform alternating processing operations, ensuring that the feeding, cleaning, and discharging of the shot are synchronized, achieving continuous cleaning of the shot without requiring machine downtime, effectively improving the cleaning efficiency. When the shot and cleaning liquid enter the cleaning cylinders 12, the rotating rods 16 inside the cleaning cylinders 12 simultaneously drive the stirring blades 17 to rotate, breaking up the various cleaning cylinders. The shot in the 12, combined with high-temperature cleaning liquid, ensures the cleaning quality of the shot. The rotating rod 16 can drive the scraper 18 to clean the residue at the bottom of the cleaning cylinder 12, ensuring comprehensive cleaning. The cleaned shot and wastewater are discharged into the separation screen plate 26 through the discharge pipe 14. Two vibrating motors 47 drive the screen plate to vibrate at high frequency. The shot slides into the shot chamber 3 along the inclined screen plate. The wastewater and impurities fall into the waste liquid chamber 2 through the screen holes and are centrally treated through the waste discharge pipe 27. The clean shot in the shot chamber 3 will enter the conveying cylinder 40 and be pushed to the outlet by the auger. At the same time, the blower 43 blows the hot air in the processing box 32 into the auger through the air supply pipe 44. The shot is dried through the air vents 42, so that the conveyed shot can be used directly. In addition, the heater 34 of the liquid supply section 9 is linked with the hot air system of the conveying section 11 to recover waste heat and effectively reduce energy consumption.

[0018] Optionally, the cleaning unit 7 includes a plurality of cleaning cylinders 12 fixed in a circular array within the processing tank 5, a plurality of feed pipes 13 connected to the top of the plurality of cleaning cylinders 12 and corresponding to the feed hopper 6, a plurality of discharge pipes 14 connected to the bottom of the plurality of cleaning cylinders 12, and a plurality of first solenoid valves 15 installed on the plurality of discharge pipes 14. When the driving unit 8 controls the processing tank 5 to rotate, the pellets to be processed can enter the plurality of cleaning cylinders 12 sequentially through the feed hopper 6 and the plurality of feed pipes 13. When some cleaning cylinders 12 are feeding and cleaning pellets, the first solenoid valve 15 at the bottom of one of the cleaning cylinders 12 is opened, and the cleaned pellets and wastewater inside can be discharged into the separation box 1 through the discharge pipe 14. This allows the plurality of cleaning cylinders 12 to feed, clean and discharge alternately in a production line, ensuring continuous processing and avoiding downtime waiting in single-cylinder cleaning mode, thus ensuring pellet processing efficiency. Furthermore, each cleaning cylinder 12 is equipped with an independent first solenoid valve 15, which can control the discharge timing individually to adapt to the needs of different cleaning cycles.

[0019] Optionally, the cleaning unit 7 further includes rotating rods 16 rotatably connected to several cleaning cylinders 12, several stirring blades 17 fixed in a circular array outside several rotating rods 16, several scrapers 18 fixed to the lower ends of several rotating rods 16 and abutting against the bottom of several cleaning cylinders 12, a protective cover 20 fixed to the bottom of the processing tank 5, a drive gear 19 rotatably installed in the protective cover 20, several transmission gears 21 rotatably installed in a circular array in the protective cover 20 and meshing with the drive gear 19, and a first motor 22 fixed in the processing tank 5. The output end of the first motor 22 is fixedly connected to the drive gear 19, and the bottom of the plurality of rotating rods 16 is fixedly connected to the plurality of transmission gears 21 respectively; In use, the first motor 22 operates, driving the drive gear 19 to rotate, which in turn meshes with several transmission gears 21, causing several rotating rods 16 to rotate synchronously. This causes the stirring blades 17 on each rotating rod 16 to rotate at high speed inside the cleaning cylinder 12, creating turbulence. This ensures that the pellets and cleaning liquid come into full contact, removing surface impurities. Several scrapers 18 rotate close to the bottom of the cleaning cylinder 12, preventing pellet deposition and ensuring thorough discharge. This avoids pellet accumulation affecting discharge and reduces the frequency of manual cleaning. The protective cover 20 seals the gear set, preventing cleaning liquid or impurities from entering and extending the life of the transmission system. The consistent rotation speed of all rotating rods 16 ensures uniform cleaning effect within each cleaning cylinder 12, resulting in consistent cleaning quality for different batches of pellets.

[0020] Optionally, the separation section 10 includes a plurality of bearing seats 23 symmetrically fixed to the inner wall of the separation box 1, a plurality of bearing springs 24 respectively fixed to the plurality of bearing seats 23, a bearing frame 25 fixed to the upper end of the plurality of bearing springs 24, a separation screen plate 26 fixed inside the bearing frame 25 and inclined, a discharge frame 45 installed at the downward inclined end of the separation screen plate 26, two vibration motors 47 symmetrically fixed to the bottom of the bearing frame 25, a waste discharge pipe 27 connected to the waste liquid chamber 2, and a guide frame 28 installed at the bottom of the separation box 1 and connected to the pellet chamber 3; The other end of the discharge frame 45 extends into the pellet chamber 3; The mixture of cleaned pellets and wastewater is discharged from the discharge pipe 14 and falls onto the inclined separation screen plate 26. At this time, two vibrating motors 47 work, driving the support frame 25 to vibrate, causing the pellets to jump and roll on the screen plate, while the wastewater flows into the waste liquid chamber 2 below through the screen holes. The discharge frame 45 is located at the bottom of the screen plate, and the dried pellets slide into the pellet chamber 3 along the inclined direction to complete the solid-liquid separation. The vibrating screen makes the pellets and wastewater separate quickly, ensuring the processing and separation efficiency of the pellets. Several support springs 24 support the support frame 25, which can absorb the vibration impact and reduce the damage to the structure of the separation box 1. The wastewater flows into the waste liquid chamber 2 through the screen holes and is finally discharged through the waste discharge pipe 27, which can be connected to an external water treatment system. The dried pellets enter the guide frame 28 and are further processed by the conveying unit 11.

[0021] Optionally, the drive unit 8 includes a second motor 29 fixed inside the control frame 4, a control gear 30 fixed at the output end of the second motor 29, and a control gear ring 31 fixedly sleeved on the outside of the processing tank 5 and meshing with the control gear 30. In use, the second motor 29 works to drive the control gear 30 to rotate, thereby meshing with the transmission control gear ring 31 and driving the processing tank 5 to rotate, so that several feed pipes 13 alternately move to the bottom of the feed hopper 6, while the gear transmission error is low, ensuring that the feed pipes 13 are aligned with the feed hopper 6.

[0022] Optionally, the liquid supply unit 9 includes a processing tank 32 fixed to the upper surface of the separation tank 1, two liquid supply tanks 33 symmetrically fixed inside the processing tank 32, two heaters 34 symmetrically fixed inside the processing tank 32 and corresponding to the two liquid supply tanks 33 respectively, a water pump 35 installed on the upper surface of the processing tank 32, two delivery pipes 36 with one end connected to the water inlet of the water pump 35 and the other end extending to the bottom of the two liquid supply tanks 33 respectively, a discharge pipe 37 with one end connected to the discharge end of the water pump 35 and the other end extending to the feed hopper 6, two second solenoid valves 38 respectively installed on the two delivery pipes 36, and water inlet pipes 39 respectively connected to the two liquid supply tanks 33. The system uses two inlet pipes 39 to alternately supply clean water to two supply tanks 33. During use, two heaters 34 heat the cleaning solution in the two supply tanks 33. Under the control of two second solenoid valves 38, the two delivery pipes 36 can be opened and closed alternately. When the water pump 35 is working, the cleaning solution can be delivered alternately through the two delivery pipes 36 and then sprayed into the cleaning cylinder 12 through the drain pipe 37. This ensures that the cleaning solution in the two supply tanks 33 can be heated to a certain temperature before use, and enables the two supply tanks 33 to work alternately, achieving uninterrupted supply. The high-temperature cleaning solution can effectively improve the cleaning effect of the pellets, ensuring that there is no residual oxide scale or oil on the surface of the pellets.

[0023] Optionally, the conveying unit 11 includes a conveying cylinder 40 fixed to the outer wall of the separation box 1 and connected to the guide frame 28 at its lower end, a third motor 46 fixed to the top of the conveying cylinder 40, a conveying auger 41 rotatably installed inside the conveying cylinder 40 and fixedly connected to the output end of the third motor 46, several ventilation holes 42 opened on the conveying auger 41, a fan 43 installed on the outer wall of the processing box 32, and an air supply pipe 44 connected at one end to the processing box 32 and at the other end to the upper end of the conveying cylinder 40. The air outlet of the fan 43 is connected to the interior of the processing box 32; The cleaned and preliminarily dehydrated pellets enter the conveying cylinder 40 through the guide frame 28. At this time, driven by the third motor 46, the conveying auger 41 is rotated to push the pellets. While the pellets are being conveyed, driven by the fan 43, hot air from the processing box 32 is blown into the conveying cylinder 40 through the air pipe 44. With the cooperation of several ventilation holes 42, the air effectively contacts the pellets, achieving flow drying of the pellets. This facilitates the direct use of the pellets after conveying, making it convenient to use. Furthermore, the hot air comes from the waste heat of the processing box 32, effectively reducing energy consumption.
