Description

Technical Field

[0001] This utility model relates to the field of surface cleaning equipment technology, and more specifically, to a shot blasting and sandblasting cleaning device. Background Technology

[0002] Shot blasting is a key piece of equipment for surface treatment in the industrial field. It mainly uses high-speed moving abrasives, such as steel shot or quartz sand, to impact and grind the surface of workpieces to remove impurities such as rust, scale, oil, and old coatings. At the same time, it can give the workpiece surface a certain roughness, enhancing the adhesion of subsequent coatings. Hanging shot blasting machines are a type of high-efficiency surface treatment equipment, mainly used for surface cleaning and strengthening of large, heavy, or irregularly shaped workpieces. Its core feature is that the workpiece is transported to the shot blasting chamber through a suspended conveyor system, realizing continuous and automated processing, which is suitable for batch production scenarios. During operation, the workpiece is sent into the closed shot blasting chamber and positioned by the suspended conveyor system. The shot blaster rotates at high speed to generate centrifugal force, which accelerates the abrasives such as steel shot to high speed and sprays them onto the workpiece surface from different angles. The impact removes rust, scale, and other impurities. At the same time, the mixture of abrasive and impurities falls to the bottom for recycling. After processing, the workpiece is transported out of the shot blasting chamber, completing the surface cleaning. Since impurities are mixed inside the abrasive during recycling, it is necessary to perform an impurity filtration operation on the abrasive.

[0003] In related technologies, during the use of shot blasting and sandblasting cleaning devices, the auger is generally driven by a drive system to rotate and circulate the abrasive containing mixed impurities, so that the abrasive can be used in a cyclical manner.

[0004] However, in the current use of shot blasting cleaning equipment, it is difficult to filter and separate the impurities in the abrasive during the recycling and circulation of mixed impurities. This leads to the recycling and circulation of abrasive, which interferes with the subsequent work of the abrasive and affects the recycling and circulation effect of the abrasive in the shot blasting cleaning equipment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a shot blasting cleaning device, including a shot blasting cleaning machine 1 and a material filtering mechanism. A hanger 2 is installed at the top inside the shot blasting cleaning machine 1, and a spiral shaft 3 is installed at the bottom inside the shot blasting cleaning machine 1. During the process of the abrasive mixed with impurities moving to the bottom of the inner wall of the shot blasting cleaning machine 1 and flowing to the spiral shaft 3, the impurity particles mixed in the abrasive are filtered and separated, avoiding the situation where impurities are difficult to separate during the abrasive recycling cycle. Therefore, the abrasive recycling effect of the shot blasting cleaning machine 1 is improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the material filtering mechanism includes a filter tank 4, which is located on both sides of the bottom of the inner wall of the shot blasting machine 1. A filter plate 5 is installed inside the filter tank 4, and mounting ports 6 are located on both sides of the top of the filter plate 5. Mounting bolts 7 are movably connected inside the mounting ports 6. A diversion and feeding mechanism is located at the bottom of the filter tank 4. When the shot blasting machine 1 sprays abrasive into the inside of the shot blasting machine 1 through the shot blaster on the right side of the inner wall and contacts the workpiece, the abrasive mixed with impurities moves downward to the spiral shaft 3. During this process, the filter plate 5 contacts the abrasive mixed with impurities before filtering the impurities in the abrasive. The impurities pass through the perforation at the top of the filter plate 5. As the hole moves downwards, the abrasive continues to move inwards along the slope of the filter plate 5 to the spiral shaft 3, thereby filtering and separating the impurities mixed in the abrasive. The diversion and feeding mechanism includes a diversion column 8 and a feeding chamber 9. The feeding chamber 9 is located at the bottom of the inner wall of the filter tank 4. The diversion column 8 is fixedly connected to the top of the filter plate 5, which can filter and divert the abrasive mixed with impurities at the top of the filter plate 5, so that the abrasive mixed with impurities moves evenly on the top of the filter plate 5. This promotes uniform filtration of the abrasive mixed with impurities by the filter plate 5, avoiding the situation where the abrasive mixed with impurities cannot move evenly on the top of the filter plate 5, which would reduce the filtration effect. Therefore, the filtration effect of the filter plate 5 is improved.

[0032] Reference Figures 2-4In a preferred embodiment, a support bar 10 located at the bottom of the filter plate 5 is fixedly connected to the top of the inner wall of the feeding chamber 9. The support bar 10 is located at the bottom of the diversion column 8, which can support and reinforce the filter plate 5 and the filter tank 4 during operation, preventing the filter plate 5 from falling due to stress in the middle during operation, thus improving the working stability of the filter plate 5. A collection groove 11 is opened at the bottom of the inner wall of the feeding chamber 9, and a collection box 12 is movably connected inside the collection groove 11, which can receive and collect impurities after being guided by the feeding chamber 9, so that the user can perform centralized processing of impurities in the subsequent operation, avoiding the situation where it is difficult to collect impurities when using the feeding chamber 9, thus improving the impurity collection effect of the feeding chamber 9.

[0033] Reference Figures 2-4 In a preferred embodiment, by providing slots 13 on the front sides of both sides of the central box 12, and embedding magnetic sheets 14 inside the slots 13, magnetic positioning can be achieved between the central box 12 and the central slot 11 during operation, thus preventing the central box 12 from shifting due to difficulty in positioning and improving the working stability of the central box 12. Magnetic grooves 15 are provided on the front sides of both sides of the inner wall of the central slot 11, located outside the slots 13. Magnetic suction sheets 16, which are magnetically connected to the magnetic sheets 14, are embedded inside the magnetic grooves 15, providing a medium for the magnetic sheets 14 to apply magnetic positioning force between the central box 12 and the central slot 11, thus preventing the magnetic sheets 14 from being unable to apply magnetic positioning force and improving the magnetic force application effect of the magnetic sheets 14.

[0034] Reference Figures 2-3 In a preferred embodiment, drawers 17 are movably connected to both sides of the bottom front side of the shot blasting machine 1. The rear side of the drawers 17 is fixedly connected to the front side of the collection box 12, which provides a force medium for the user to pull the collection box 12. This avoids the collection box 12 being difficult to move and pull due to the magnetic attraction of the magnetic sheet 14 and the magnetic suction sheet 16. Therefore, the ease of operation of the collection box 12 is improved. The bottom sides of the inner wall of the filter tank 4 are provided with screw grooves 18 that communicate with the installation port 6. The bottom of the mounting bolt 7 is threadedly connected to the screw groove 18, which provides space for the mounting bolt 7 to be threadedly connected to the filter tank 4 and to apply threaded fastening force to the filter plate 5. This avoids the situation where the mounting bolt 7 is difficult to effectively fasten the filter plate 5 during use. Therefore, the installation force application effect of the mounting bolt 7 is improved.

[0035] Specifically, the working process or principle of this shot blasting cleaning device is as follows: During use, the filter plate 5 is placed inside the filter groove 4. At this time, the mounting port 6 moves with the filter plate 5 and aligns with the screw groove 18. Then, the mounting bolt 7 is held and passed through the mounting port 6 through the filter plate 5. Using an external screwdriver, the mounting bolt 7 is rotated and installed into the screw groove 18, so that the mounting bolt 7 mates with the screw groove 18 and the mounting hole, thus securing the filter plate 5 and the filter groove 4 with a threaded fastener. It should be noted that the mesh size of the filter plate 5 can be selected and replaced according to the actual filtration requirements of the abrasive. The mounting bolt 7 mates with the mounting port 6. 6. Secure the filter plate 5 and filter tank 4 with threads using the screw groove 18. Then, move the collection box 12 to align with the collection tank 11 via the drawer 17, and move the collection box 12 backward to install it into the collection tank 11. This allows the collection box 12 to align and communicate with the discharge chamber 9 and filter tank 4 through the collection tank 11, preparing for the collection box 12 to receive and collect the impurities filtered by the filter plate 5. At this time, the magnetic sheet 14 moves into the collection tank 11 through the sleeve groove 13, following the collection box 12, and contacts and engages with the magnetic suction sheet 16 and magnetic groove 15, aligning the collection box 12 with the collection tank 11 after installation. Magnetic positioning is performed between 11. When the external workpiece is moved into the shot blasting machine 1 by the hanger 2, the closed doors on both sides of the front of the shot blasting machine 1 are flipped to close the machine. The shot blasting machine 1 sprays abrasive onto the workpiece surface through the shot blaster on the right side. When cleaning the workpiece surface, since the filter plate 5 is at the same angle to the bottom of the inner wall of the shot blasting machine 1, as the abrasive comes into contact with the workpiece and removes impurities, it moves downward. The filter plate 5 contacts the abrasive mixed with impurities first. At this time, the diverter column 8 blocks and divides the abrasive mixed with impurities that has moved to the top of the filter plate 5. The flow operation causes the abrasive mixed with impurities to move evenly on the top of the filter plate 5, prompting the filter plate 5 to perform uniform filtration of the abrasive mixed with impurities. During this process, the impurities mixed in the abrasive pass through the perforated opening at the top of the filter plate 5 and move downwards, passing through the feeding chamber 9 and into the collection tank 11. At this time, the collection box 12 receives and collects the impurities so that the staff can perform unified processing of the impurities later. At the same time, the support bar 10 supports and reinforces the bottom of the filter plate 5, while the abrasive continues to move towards the rotating shaft due to the slope of the filter plate 5, so that the rotating shaft can circulate and transport the filtered abrasive.

[0036] It should be noted that the shot blasting cleaning machine 1, the hanger 2 and the spiral shaft 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
