Description
Technical Field
[0001] This utility model relates to the field of workpiece processing technology, specifically to a sand shot recovery device for a through-type shot blasting machine. Background Technology
[0002] In industrial sectors such as machinery manufacturing, auto parts, and shipbuilding, shot blasting is a core process for removing rust, scale, and strengthening workpiece surfaces, relying on high-speed shot blasting to achieve the surface treatment effect.
[0003] Publication No. CN220279367U discloses a through-feed shot blasting machine, comprising: a base plate, a conveyor fixed to the top of the base plate, a housing fitted in the middle of the conveyor, the housing being fixed to the top of the base plate by support legs, a storage tank fixed to the top of the base plate, two guide plates symmetrically fixed inside the housing, a screening frame fixed below the two guide plates, an inclined bottom, and two symmetrically sliding baffles connected inside the housing. By setting up guide plates, screening plates, a first discharge hopper, a storage tank, and a second discharge hopper, with the cooperation of the guide plates, steel shot passing through the conveyor belt can fall into the screening frame. The inclination and the mesh openings of the mesh allow for screening of steel shot and debris after collision with the workpiece, separating and collecting waste steel shot and debris separately, thus avoiding affecting the working efficiency of the shot blasting machine.
[0004] As shown in the above technical solution, although the device achieves preliminary screening of steel shot and debris through the guide plate and screening frame, and avoids the impact of waste steel shot and debris on the working efficiency of shot blasting machine to a certain extent, it is difficult to completely separate the fine impurities attached to the surface of steel shot. The residual fine impurities will reduce the uniformity of steel shot blasting, resulting in uneven surface treatment of workpieces, and problems such as incomplete local rust removal and oxide scale residue, which affect the appearance and performance of workpieces.

Detailed Implementation
[0025] 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.
[0026] See Figures 1-4 This utility model provides the following two technical solutions:
[0027] First embodiment: A shot blasting machine shot recovery device, comprising:
[0028] Conveying roller conveyor 1 is used to carry and transport the workpiece to be shot blasted, so as to realize continuous shot blasting operation;
[0029] Shot blasting machine 2 is fixedly installed on the top of conveyor roller 1. Shot blasting machine 2 is used to propel sand shot to the surface of the workpiece at high speed. The impact force of the sand shot is used to remove rust, oxide scale and other impurities from the surface of the workpiece, so as to clean and strengthen the surface of the workpiece.
[0030] Collection component 3 is fixedly installed at the bottom of conveyor roller 1 and located below shot blasting machine 2. Collection component 3 is used to collect sand and shot scattered during shot blasting.
[0031] The cleaning component 4 is fixedly installed inside the collection component 3. The cleaning component 4 is used to clean the collected sand pellets, remove impurities and dust attached to the surface of the sand pellets, and restore the sand pellets to a clean state so that they can be recycled.
[0032] The collecting component 3 consists of a collecting hopper 31 and a conveying channel 32. The collecting hopper 31 is fixedly installed at the bottom of the conveying roller 1, and the conveying channel 32 is fixedly installed at the bottom of the collecting hopper 31. The collecting hopper 31 and the conveying channel 32 are connected. The cleaning component 4 is fixedly installed inside the conveying channel 32.
[0033] The cleaning component 4 includes a water spray pipe 41, which is fixedly installed at the top of the inner wall of the conveying channel 32. Multiple nozzles 42 are evenly installed on the water spray pipe 41. A water collection tank 43 is provided at the end of the collecting component 3. The water collection tank 43 is connected to the water spray pipe 41 through a connecting pipe 44. A water pump 45 is fixedly installed on the connecting pipe 44. A rotating shaft 46 is rotatably installed inside the conveying channel 32. A brush 47 is fixedly installed on the rotating shaft 46. A motor 48 is fixedly installed on the outer wall of the conveying channel 32. The output end of the motor 48 passes through the conveying channel 32 and is fixedly connected to the rotating shaft 46.
[0034] Multiple sets of water spray pipes 41 and rotating shafts 46 are installed in the conveying channel 32, and multiple water spray pipes 41 are connected to the water collection tank 43 through the same connecting pipe 44.
[0035] The conveyor roller 1 carries and transports the workpiece to be shot blasted, allowing the workpiece to enter the area below the shot blasting machine 2 for shot blasting. The shot blasting machine 2 propels sand shot at high speed onto the surface of the workpiece, completing the cleaning and strengthening of the workpiece. During the shot blasting process, the sand shot that falls off is collected by the collection hopper 31 in the collection assembly 3, and then conveyed downward through the conveying channel 32. In the conveying channel 32, the nozzles 42 on the water spray pipe 41 spray water from the water collection tank 43 through the connecting pipe 44 and the water pump 45 to rinse the sand shot. At the same time, the motor 48 drives the rotating shaft 46 to rotate, driving the brushing component 47 to brush the sand shot. Under the multiple actions, impurities and dust on the surface of the sand shot are removed. The setting of multiple sets of water spray pipes 41 and rotating shafts 46 can further improve the cleaning effect.
[0036] In this embodiment, by setting up a collection component 3 and a cleaning component 4, the entire process of shot blasting recovery and cleaning is automated. The collection hopper 31 and conveying channel 32 of the collection component 3 can promptly receive the shot blasting particles scattered during the shot blasting operation, preventing the accumulation of shot blasting particles from affecting equipment operation. At the same time, the conveying channel 32 directs the shot blasting particles to the cleaning area, providing a stable material transport path for subsequent cleaning processes. In the cleaning component 4, the water spraying and rinsing by the water spray pipes 41 and nozzles 42, and the mechanical brushing by the motor 48 driving the brushing components 47 work together. With the layout of multiple sets of water spray pipes 41 and rotating shafts 46, it can efficiently remove impurities such as rust, oxide scale, and dust attached to the surface of the shot blasting particles, so that the cleanliness of the shot blasting particles meets the standard for recycling. This not only reduces the cost of manual intervention, but also reduces the consumption of consumables through the reuse of shot blasting particles. The cleaned shot blasting particles are returned to the shot blasting machine 2 for continued operation, which can also ensure the stability of the impact force of shot blasting and avoid the problem of uneven surface treatment of workpieces caused by the accumulation of impurities in shot blasting particles. This improves the overall performance of the equipment in terms of production efficiency, cost control, and process quality.
[0037] The second embodiment differs from the first embodiment in that: a shot blasting box 5 is fixedly installed at the right end of the water collection tank 43, and a connecting plate 6 is fixedly installed between the end of the conveying channel 32 and the shot blasting box 5. The connecting plate 6 is located above the water collection tank 43, and multiple filter holes 7 are evenly opened on the connecting plate 6.
[0038] Both ends of the connecting plate 6 are fixedly equipped with baffles 8.
[0039] The shot blasting box 5, which is fixedly installed at the right end of the water collection tank 43, is connected to the conveying channel 32 via the connecting plate 6. When the sand shot processed by the cleaning component 4 falls along the conveying channel 32, it will first pass through the evenly distributed filter holes 7 on the connecting plate 6. The water and impurities after the cleaning process will flow back into the water collection tank 43 through the filter holes 7. The cleaned sand shot will slide into the shot blasting box 5 through the connecting plate 6. The baffles 8 at both ends form a lateral enclosure to prevent the sand shot from splashing to both sides during the fall and avoid recycling losses caused by scattering.
[0040] In this embodiment, the coordinated design of the connecting plate 6, filter hole 7, and baffle 8 achieves efficient separation and directional transport of sand shot, cleaning wastewater, and impurities: the filter hole 7 intercepts residual impurities in the sand shot while allowing the cleaning wastewater to flow back to the collection tank 43 for recycling, reducing water consumption; the baffle 8, in conjunction with the filter hole 7, ensures that the sand shot slides smoothly into the shot blasting box 5, preventing the sand shot from splashing to both sides during the fall and avoiding recycling losses due to scattering; the centralized collection of the cleaned sand shot in the shot blasting box 5 provides convenient conditions for the recycling of the sand shot.
[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0042] In use, the conveyor roller 1 carries and transports the workpiece to be shot blasted, sending it below the shot blasting machine 2. The shot blasting machine 2 propels sand shot at high speed to clean and strengthen the surface of the workpiece. During the process, the sand shot that falls off is collected by the collection hopper 31 in the collection assembly 3, and then conveyed downward through the conveying channel 32. The sand shot entering the conveying channel 32 is rinsed by water spray from the nozzle 42 of the water spray pipe 41, and mechanically brushed by the motor 48 driving the rotating shaft 46 to drive the brushing parts 47, thus removing surface impurities and dust. The cleaning process is further enhanced by multiple sets of water spray pipes 41 and rotating shaft 46. After cleaning, the sand shot falls along the conveying channel 32 to the connecting plate 6. Under the screening of the filter holes 7, fine impurities and cleaning wastewater flow back to the water collection tank 43 for recycling. Clean sand shot that meets the particle size requirements passes through the connecting plate 6 and slides smoothly into the shot blasting box 5 under the protection of the baffle 8 for centralized collection. Finally, the clean sand shot collected in the shot blasting box 5 is transported back to the shot blasting machine 2 to achieve recycling and complete the entire shot blasting and sand shot recovery process.
