Description

[0001] The present invention relates to the technical field of steel processing and cleaning, and specifically to a cleaning device for section steel processing in steel structure manufacturing. Background Art

[0002] In the modern industrial system, steel structures are widely used in many fields such as construction projects, bridge construction, shipbuilding, and mechanical equipment due to their advantages of high strength, light self-weight, short construction period, and recyclability. As a basic component of steel structures, the processing quality of section steel directly affects the overall performance and safety of steel structures. Therefore, efficiently and thoroughly cleaning the surface of section steel has become a key link in ensuring the quality of steel structures, and the importance of section steel processing and cleaning equipment has become increasingly prominent.

[0003] Due to the different widths of the plates, when traditional cleaning equipment is in use, when encountering special-shaped plate parts with different widths, it is necessary for workers to adjust the discharge parameters of the shot blasting machine outlet according to the width of the plate. Adjusting the discharge parameters will cause the cleaning process to be interrupted, and it is necessary for workers to constantly observe the size of the plate, resulting in a cumbersome cleaning process and reducing the cleaning efficiency. Summary of the Invention

[0004] The present invention adjusts the air intake volume of the shot blasting machine and the size of the outlet of the discharge port according to the width of the plate, so as to make more shot be thrown out by increasing the outlet of the discharge port, and at the same time increase the air pressure to improve the throwing speed of the shot, which can effectively remove impurities such as rust and scale on the surface of large plates.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention adjusts the air intake volume of the shot blasting machine and the caliber size of the discharge port through the width of the plate. By increasing the discharge port, more shot is thrown out. At the same time, the air pressure is increased to improve the projection speed of the shot, which can effectively remove impurities such as rust and scale on the surface of large plates. Conversely, for small plates, reducing the discharge port and air pressure can avoid damage to the plate caused by excessive shot and excessive impact force, ensuring that the shot blasting cleaning effect is uniform. Moreover, precisely controlling the size of the discharge port and air pressure can make the distribution of the shot on the plate surface more uniform, improving the cleaning effect.

[0015] While expanding the discharge port, the present invention increases the air extraction volume of the suction groove, so as to increase the air extraction volume to timely suck away a large amount of dust generated during the shot blasting process, prevent it from spreading in the workshop, reduce the dust concentration in the workshop, improve the working environment of workers, and ensure the physical health of workers. At the same time, synchronously increasing the air extraction volume can maintain the stability of the air flow in the shot blasting chamber, reduce the influence of air flow disorder on the projection trajectory and speed of the shot, ensure that the shot can be projected onto the workpiece surface in a stable state, and improve the uniformity and consistency of shot blasting.

[0016] When the plate is enlarged, the present invention synchronously increases the spraying range of the cleaning agent, so that the usage amount of the cleaning agent matches the actual cleaning requirements of the plate, avoiding waste of the cleaning agent, saving the cost of the cleaning agent, and reducing the burden of subsequent sewage treatment. At the same time, when the discharge and air intake volume of the shot blasting machine increase, synchronously increasing the spraying amount of the cleaning agent can improve the overall cleaning efficiency, reduce the cleaning time of a single section steel, thereby improving the production efficiency of section steel processing, and also ensuring the integrity of cleaning.

Specific implementation manner

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a steel structure manufacturing section steel processing and cleaning device, including a conveying table 1, an outer cover 2 is installed at the upper end of the conveying table 1, and a limiting plate 3 is provided at one end of the outer cover 2; A movable plate 4 is installed inside the outer cover 2, one end of the movable plate 4 is connected to a gear A 7, a gear B 8 is meshed on one side of the gear A 7, one end of the gear B 8 is connected to an air supply pipe 10, one end of the air supply pipe 10 is connected to a shot blasting machine 11, a discharge port 12 is provided at the lower end of the shot blasting machine 11, a movable rod 13 is provided on one side of the movable plate 4, one end of the movable rod 13 is connected to a connecting frame 15, and one end of the connecting frame 15 is connected to a baffle 16 A rack A 17 is connected to one side of the connecting frame 15, a gear C 18 is connected to one side of the rack A 17, a connecting pipe A 20 and an air suction groove 21 are provided on one side of the rack A 17, an air suction groove 21 is installed on one side of the outer cover 2, and one end of the connecting pipe A 20 is connected to a pump 22; The outside of the pump 22 communicates with a storage tank 24, a spray head A 26 and a spray head B 27 are communicated on one side of the storage tank 24, a gear D 28 is provided on one side of the spray head B 27, a rack B 29 is connected to one side of the gear D 28, one end of the rack B 29 is connected to an air pressure pipe 32, and one end of the air pressure pipe 32 is connected to a branch pipe 33.

[0021] In an alternative embodiment, two sets of limit plates 3 are installed at the upper end of the conveying table 1, and the limit plates 3 are located at the feeding port of the conveying table 1. When in use, the steel plate to be cleaned is placed on the upper end of the conveying table 1. When the steel plate is conveyed, the steel plate will be automatically positioned at the center of the conveying table 1 by the force of the limit plates 3 and conveyed.

[0022] In an alternative embodiment, two sets of movable plates 4 are provided on both sides of the outer casing 2. Spring rods 5 are connected to the upper ends of the two sets of movable plates 4, and the other ends of the spring rods 5 are connected to the outer casing 2. A connecting rod 6 is connected to the lower end of the movable plate 4. The connecting rod 6 penetrates through the outer casing 2 and extends to the lower end of the conveying table 1 and is connected to gear A 7. When the steel plate moves into contact with the movable plate 4, the movable plate 4 will flip backward due to the extrusion of the steel plate. And due to the action of the spring rod 5, when the steel plate moves, the movable plate 4 will always adhere to the outer wall of the steel plate. When the movable plate 4 flips backward, it drives the lower connecting rod 6 to rotate synchronously. When the connecting rod 6 rotates, it drives gear A 7 to rotate synchronously.

[0023] In an alternative embodiment, a rotating shaft A 9 is fixedly connected to one end of gear B 8 close to the air supply pipe 10. One end of the rotating shaft A 9 penetrates through the air supply pipe 10 and extends to the inside and is connected to valve A. One end of the air supply pipe 10 is connected to a pressure supply device. When gear A 7 rotates, it drives gear B 8 to rotate. When gear B 8 rotates, it expands the valve inside the air supply pipe 10, thereby increasing the air supply volume of the air supply pipe 10 to the shot blasting machine 11. On the contrary, when the outer diameter of the steel plate shrinks, the movable plate 4 will reset by the force of the spring rod 5. When the movable plate 4 resets, it will synchronously reduce the valve inside the air supply pipe 10, so as to adjust the amount of air pressure according to the width of the plate.

[0024] In an alternative embodiment, the movable rod 13 is provided on one side of each of the two groups of movable plates 4. The contact surface between the movable rod 13 and the movable plate 4 is an inclined surface. A spring 14 is provided outside the movable rod 13. One end of the spring 14 is connected to the outer cover 2, and the other end is connected to the connecting frame 15. The baffle 16 is located on both sides of the discharge port 12 and extends through the outer cover 2 to the outside. When the movable plate 4 flips, it will contact the movable rod 13. Since the contact surface between the movable rod 13 and the movable plate 4 is an inclined surface, when the movable plate 4 contacts the movable rod 13, it will squeeze the movable rod 13 to move to one side. Thus, when the movable rod 13 moves to one side, it will synchronously push the connecting frame 15 to move. When the connecting frame 15 moves, it will synchronously drive the baffle 16 to move, thereby expanding the diameter of the discharge port 12. At the same time, combined with the above, by adjusting the width of the plate, the air intake volume of the shot blasting machine 11 and the diameter of the discharge port 12 are adjusted. Thus, by increasing the discharge port 12, more shot is thrown out. At the same time, the air pressure is increased to improve the ejection speed of the shot, which can effectively remove impurities such as rust and scale on the surface of large plates. On the contrary, for small plates, the discharge and air pressure are reduced to avoid damage to the plates caused by excessive shot and excessive impact force, ensuring that the shot blasting cleaning effect is uniform. Moreover, by precisely controlling the size of the discharge port 12 and the air pressure, the distribution of the shot on the plate surface can be made more uniform, improving the cleaning effect. Also, it is not necessary for the staff to observe near the equipment all the time during use, reducing the cumbersome steps during use. When the plate shrinks, as the movable plate 4 resets, the movable rod 13 will also reset by the force of the spring 14.

[0025] In an alternative embodiment, one end of the connecting pipe A20 and one end of the connecting pipe C34 are both connected to the pump 22. A valve B is provided inside the connecting pipe C34. One end of the gear C18 close to the connecting pipe C34 is fixedly connected to a rotating shaft B19. The rotating shaft B19 extends through the connecting pipe C34 to the inside and is connected to the valve B. One end of the connecting pipe A20 and one end of the connecting pipe C34 are both connected to the suction slot 21. The connection between the connecting pipe A20 and the suction slot 21 is in a normally open state. During normal use, only one group of connecting pipes A20 sucks dust through the pump 22. When the connecting frame 15 moves outward due to the expansion of the plate, the rack A17 will move synchronously. When the rack A17 moves, it will drive the gear C18 to rotate. Thus, when the gear C18 rotates, it will open the valve B inside the connecting pipe C34. Furthermore, while the discharge port 12 expands, the air extraction volume of the suction slot 21 is increased. Thus, by increasing the air extraction volume, a large amount of dust generated during the shot blasting process can be sucked away in time, preventing it from spreading in the workshop, reducing the dust concentration in the workshop, improving the working environment of the workers, and protecting the health of the workers. At the same time, synchronously increasing the air extraction volume can maintain the stability of the air flow in the shot blasting chamber, reducing the influence of air flow disorder on the ejection trajectory and speed of the shot, ensuring that the shot can be ejected onto the workpiece surface in a stable state, and improving the uniformity and consistency of shot blasting.

[0026] In an alternative embodiment, connecting pipes B23 are connected to the outside of both groups of pump machines 22. The other end of the connecting pipe B23 is connected to a storage tank 24. Multiple groups of delivery pipes 25 are connected to the outside of the storage tank 24. The spray head A26 and the spray head B27 are connected to the storage tank 24 through the delivery pipes 25. A cleaning agent is stored inside the storage tank 24. While the pump machine 22 is pumping air, part of the gas will be delivered into the storage tank 24 through the connecting pipe B23, thereby increasing the air pressure inside the storage tank 24, so that the cleaning agent flows out through the delivery pipe 25 and is sprayed through the spray head A26. After the connecting pipe C34 expands the board and the valve B inside is opened, the pump machine 22 connected to the connecting pipe C34 will pump air at this time. When pumping air, the pump machine 22 connected to the connecting pipe C34 will synchronously deliver air pressure to the inside of the storage tank 24 through the connecting pipe B23.

[0027] In an alternative embodiment, a valve C is provided inside the delivery pipe 25 connected to the spray head B27. One end of a gear D28 is provided with a rotating rod, and the rotating rod passes through the delivery pipe 25 and is connected to the valve C. The inside of the delivery pipe 25 connected to the spray head B27 is in a closed state in the initial state.

[0028] In an alternative embodiment, two sets of racks B29 are provided. A fixing rod 30 is connected between the two sets of racks B29. One end of the rack B29 is fixedly connected to a push rod 31. One end of the push rod 31 is connected to a pneumatic pipe 32. One end of the push rod 31 located inside the pneumatic pipe 32 is fixedly connected to a return spring 35. The other end of the return spring 35 is connected to the inner wall of the pneumatic pipe 32. One end of a branch pipe 33 is connected to the connecting pipe B23, and this connecting pipe B23 is connected to the pump machine 22 connected to the connecting pipe C34. When the connecting pipe B23 connected to the connecting pipe C34 delivers air pressure, part of the air pressure will enter the inside of the pneumatic pipe 32 through the branch pipe 33. After the air pressure enters the inside of the pneumatic pipe 32, it will push the push rod 31 outwards. When the push rod 31 is pushed outwards, the two sets of racks B29 will be pushed to move synchronously. When the racks B29 move, they will drive the two sets of gears D28 to rotate, thereby opening the valve C inside the delivery pipe 25 connected to the spray head B27. After the valve C is opened, the spray head A26 and the spray head B27 will spray the cleaning agent synchronously, so that when the board expands, the spraying range of the cleaning agent will also increase synchronously, so that the amount of cleaning agent used matches the actual cleaning requirements of the board, avoiding waste of the cleaning agent, saving the cost of the cleaning agent, and reducing the burden of subsequent sewage treatment. At the same time, when the discharge and air intake of the shot blasting machine 11 increase, synchronously increasing the spraying amount of the cleaning agent can improve the overall cleaning efficiency, reduce the cleaning time of a single section steel, thereby improving the production efficiency of section steel processing, and also ensuring the integrity of cleaning. When the valve B inside the connecting pipe C34 is closed when the board becomes smaller, the push rod 31 will automatically reset by the force of the return spring 35, and the valve C will be closed synchronously during the reset.

[0029] Working principle: When in use, place the steel plate to be cleaned on the upper end of the conveying table 1. When the steel plate is conveyed, the steel plate will be automatically positioned at the center of the conveying table 1 by the force of the limiting plate 3 and conveyed; When the steel moves to contact the movable plate 4, the movable plate 4 will flip backward due to the extrusion of the steel plate. And due to the action of the spring rod 5, when the steel plate moves, the movable plate 4 will always adhere to the outer wall of the steel plate. When the movable plate 4 flips backward, it will drive the connecting rod 6 at the lower end to rotate synchronously. When the connecting rod 6 rotates, it will drive the gear A7 to rotate synchronously. When the gear A7 rotates, it will drive the gear B8 to rotate. When the gear B8 rotates, it will expand the valve inside the air supply pipe 10, thereby increasing the air supply volume of the air supply pipe 10 to the shot blasting machine 11. On the contrary, when the outer diameter of the steel plate shrinks, the movable plate 4 will reset by the force of the spring rod 5. When the movable plate 4 resets, it will synchronously reduce the valve inside the air supply pipe 10, so as to adjust the amount of air pressure according to the width of the plate. When the movable plate 4 flips, it will contact the movable rod 13. Since the contact surface between the movable rod 13 and the movable plate 4 is an inclined surface, when the movable plate 4 contacts the movable rod 13, it will squeeze the movable rod 13 to move to one side. Thus, when the movable rod 13 moves to one side, it will synchronously push the connecting frame 15 to move. When the connecting frame 15 moves, it will synchronously drive the baffle 16 to move, thereby expanding the diameter of the discharge port 12. At the same time, combining the above, the air intake volume of the shot blasting machine 11 and the diameter of the discharge port 12 are adjusted according to the width of the plate; During normal use, only one set of connecting pipe A20 sucks dust through the pump 22. When the width of the plate expands and causes the connecting frame 15 to move outward, it will make the rack A17 move synchronously. When the rack A17 moves, it will drive the gear C18 to rotate. Thus, when the gear C18 rotates, it will open the valve B inside the connecting pipe C34, and then increase the air extraction volume of the air suction groove 21 while the discharge port 12 expands; While the pump 22 is pumping air, it will convey part of the gas to the inside of the storage tank 24 through the connecting pipe B23, thereby increasing the air pressure inside the storage tank 24, so that the cleaning agent flows out through the conveying pipe 25 and is sprayed through the nozzle A26. After the valve B inside the connecting pipe C34 is opened when the width of the plate expands, at this time, the pump 22 connected to the connecting pipe C34 will pump air. When pumping air, the pump 22 connected to the connecting pipe C34 will synchronously convey air pressure to the inside of the storage tank 24 through the connecting pipe B23; The inside of the delivery pipe 25 connected to the nozzle B27 is in a closed state initially. When air pressure is delivered through the connecting pipe B23 connected to the connecting pipe C34, part of the air pressure will enter the inside of the air pressure pipe 32 through the branch pipe 33. After the air pressure enters the inside of the air pressure pipe 32, it will push the push rod 31 outwards. When the push rod 31 is pushed outwards, it will synchronously push the two groups of racks B29 to move. When the racks B29 move, they will drive the two groups of gears D28 to rotate, thereby opening the valve C inside the delivery pipe 25 connected to the nozzle B27. After the valve C is opened, the nozzle A26 and the nozzle B27 will spray the cleaning agent synchronously, so that when the board expands, the spraying range of the cleaning agent will also increase synchronously. When the valve B inside the connecting pipe C34 is closed when the board becomes smaller, the push rod 31 will automatically reset by the force of the return spring 35, and the valve C will be closed synchronously during the resetting.
