It includes a rust removal box with a support plate inside, on which two first sliding plates are fixedly connected. This mechanically and electrically automated rust removal device, through the arrangement of first sliding plates, racks, gears, transmission rods, and cylinders, allows for rapid rust removal of objects. After one end face of the object is rusted, it can be quickly flipped to rapidly remove rust from the other end face. No manual assistance is required during the flipping process, effectively improving the rust removal efficiency of the device.

[0004] However, during the current shot blasting process, the rust and scale removed by the impact and friction of the shot will turn into fine particles. At the same time, some metal fragments may also be generated during the collision of the shot with the workpiece. These can all form dust that flies in the air, which not only pollutes the working environment and affects the health of operators, but also may lead to occupational diseases such as pneumoconiosis if inhaled for a long time, causing long-term adverse effects on surrounding equipment and facilities and workers. Utility Model Content

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figures 1-6 As shown, this utility model provides an automated rust removal device suitable for mechanical and electrical applications, including a base plate 1 and a shot blasting assembly 2. A housing 3 is fixed to the top of the base plate 1 via support legs. A hopper 4 is fixedly connected to the bottom of the housing 3, and a storage tank 5 is fixedly connected to the bottom of the hopper 4. A dust removal assembly 6 is provided on the base plate 1, and a make-up air assembly 7 is provided on the top of the housing 3. The dust removal assembly 6 includes a filter barrel 601, an induced draft fan 602, and an air compressor assembly 603, which are respectively fixed to the top of the base plate 1. A top cover 604 is fixed to the top of the filter barrel 601, and a cloth bag 605 is fixed to the bottom of the top cover 604.

[0029] The overall effect of Embodiment 1 is that during the rust removal process by the shot blasting component 2 using shot blasting, the dust removal component 6 and the air supply component 7 start working together. The induced draft fan 602 can draw the particulate dust generated in the housing 3 into the filter barrel 601 for filtration by the filter bag 605, preventing the dust-containing air from drifting into the surrounding air and polluting the working environment. The air compressor component 603 can blow high-pressure air into the filter bag 605, causing the filter bag 605 to vibrate and shake, thereby removing the particulate dust adsorbed on the surface of the filter bag 605 and preventing the filter bag 605 from clogging, so as to maintain the filtration effect of the filter bag 605. The air supply component 7 can improve the suction effect of dusty gas.

[0030] Example 2: As Figures 1-6As shown, an air inlet 606 is provided in the middle of the top cover 604. A dust conveying pipe 607 is fixed inside the air inlet 606, and one end of the dust conveying pipe 607 is fixedly connected to a ring pipe 608. Suction pipes 609 are fixedly connected at equal intervals on the surface of the ring pipe 608. One end of each suction pipe 609 penetrates the surface wall of the storage tank 5 and is fixedly connected to an air collecting hood 610. The surface wall of the storage tank 5 has mounting holes 611 arranged in a circular array to match the suction pipes 609. The suction pipes 609 are fixed in the corresponding mounting holes 611. The air inlet of the blower 602 is fixedly connected to the air outlet of the filter tank 601 by a connecting pipe 612, and the air outlet of the blower 602 is fixedly connected to an exhaust pipe. The surface wall of the filter tank 601 has a cleaning port 613, and the air outlet of the air compressor assembly 603 is fixedly connected to an air conveying pipe. Pipe 614, one end of which is fixedly connected to cleaning port 613; the air supply assembly 7 includes a blower 701 fixedly mounted on the top of the housing 3, the output end of the blower 701 is fixedly connected to an air supply pipe 702, one end of the air supply pipe 702 is fixedly connected to an air outlet 703, the bottom of the air outlet 703 is fixedly mounted on the top of the housing 3; the top of the housing 3 is provided with an air supply port 704 adapted to the air outlet 703, the inner wall of the air supply port 704 is fixedly provided with a sealing plate 705, and the bottom of the sealing plate 705 is provided with a circumferential array of diversion holes 706; the shot blasting assembly 2 is symmetrically arranged on both sides inside the housing 3, the bottom of the storage tank 5 is fixedly connected to a return pipe connected to the shot blasting assembly 2; the bottom of the storage tank 5 is symmetrically fixed with four support legs, and the bottom of the support legs is fixedly mounted on the top of the base plate 1.

[0031] The overall effect of embodiment 2 is that the mounting hole 611 allows the suction pipe 609 to be smoothly inserted into the storage tank 5 and the air collection hood 610 to be installed. The air compressor assembly 603 can blow out the high-pressure gas stored therein according to the time and frequency set in the program. Through the air supply pipe 614 and the cleaning port 613, the high-pressure gas acts on the filter bag 605, causing the filter bag 605 to vibrate and shake. The setting of the sealing plate 705 and the diversion hole 706 can evenly disperse the air introduced into the box 3 at the air outlet hood 703 and the air supply port 704, so that the blown air can flow evenly above the box 3. The return pipe of the storage tank 5 can transport the collected shot back to the shot blasting assembly 2, so that the shot can be automatically recycled.

[0032] Working Principle: When rust removal is required on a workpiece, the workpiece is placed into chamber 3 and the chamber door is closed to seal chamber 3, allowing the rust removal process to begin. At this time, the shot blasting assembly 2, the induced draft fan 602, and the blower 701 all start working. The shot blasting assembly 2 propels shot at high speed onto the surface of the workpiece to remove rust. Simultaneously, the induced draft fan 602 and the blower 701, working together, create suction at the bottom of chamber 3. The blower 701, through the air supply pipe 702 and the air outlet hood 703, can slightly blow air downwards from the top of chamber 3, removing rust from the upper part of chamber 3. The downward airflow allows the debris and particulate dust generated during the rust removal process to flow downwards efficiently. After impacting the workpiece surface, the projectiles fall to the bottom of the housing 3 due to gravity. The falling projectiles then enter the storage tank 5 through a small hole below the hopper 4. During the suction process of the induced draft fan 602, multiple air collection hoods 610 create an attractive force zone above the storage tank 5. The projectiles entering the storage tank 5 must pass through this attractive force zone to fall to the bottom of the storage tank 5. At this time, the air that enters with the projectiles is drawn into the suction... Through the inlet pipe 609, connected to the ring pipe 608 and the dust conveying pipe 607, air containing dust particles is transported from the inlet 606 to the filter bag 605 in the filter barrel 601. The filter bag 605 intercepts and filters the dust particles in the air. The filtered air that meets the standards can then be discharged from the filter barrel 601 through the connecting pipe 612, thus completing the dust filtration. When the dust in the filter bag 605 needs to be cleaned after the rust removal device has been working for a period of time, the operator selects the cleaning button, the air compressor assembly 603 starts, and the pulse controller can release the stored high-pressure air. The high-pressure air is blown out and guided by the air supply pipe 614 into the filter bucket 601 through the cleaning port 613. It is then sprayed onto the filter bag 605. The compressed air is sprayed out in the form of a high-speed airflow, forming a strong impact force that acts on the surface of the filter bag 605. This impact force causes the filter bag 605 to expand and vibrate instantly, causing the dust adhering to the surface of the filter bag 605 to fall off under the vibration. After standing still for a period of time, the dust will accumulate loosely at the bottom of the filter bag 605. Finally, the personnel can open the top cover 604 to take out the filter bag 605 and pour out the dust.

[0033] The wiring diagrams of the induced draft fan 602, air compressor assembly 603, blower 701, shot blasting assembly 2, and external rust removal device control unit in this utility model are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring layouts of the induced draft fan 602, air compressor assembly 603, blower 701, and shot blasting assembly 2 will not be explained in detail. In summary, the problems raised in the background above are solved.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
