Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a dust removal device for steel structure processing. Background Technology

[0002] Steel structure fabrication is a process of transforming steel into building structural components through a series of complex and precise processes. In steel structure fabrication, steel is often cut, ground, and welded, so that the originally scattered steel gradually becomes steel beams and steel columns that support the building.

[0003] In the prior art, Chinese Patent Publication No. CN220717161U discloses a dust removal device for steel structure processing, relating to the field of steel structure processing technology. It includes a support frame and a dust collector body. The dust collector body is fixedly connected to the middle of the support frame. An outlet pipe is fixedly connected to the side of the dust collector body. A fixed shaft is fixedly connected to the inner wall of the outlet pipe. A movable cover plate is movably connected to the outer wall of the outlet pipe. A second movable cover plate is provided on the other side of the first movable cover plate. The first and second movable cover plates are located at the axis of the fixed shaft. The second movable cover plate is movably connected to the outer wall of the outlet pipe. This utility model, through the combined action of the first and second movable cover plates, the fixed shaft, the motor, the connecting gear, the first disc gear, and the second disc gear, protects the outlet pipe through the first and second movable cover plates, thereby preventing dust from falling into the interior of the outlet pipe and enhancing the cleanliness of the device.

[0004] In actual production and use, although this type of dust removal device for steel structure processing can remove dust generated during steel structure processing, it mainly focuses on protecting the outlet pipe through movable cover plate one and movable cover plate two to prevent dust from falling into the interior of the outlet pipe. However, the dust generated during steel structure processing may drift away from the sides and bottom of the steel. This type of dust removal device for steel structure processing does not have a side suction device, which may lead to incomplete dust removal during steel structure processing, resulting in poor performance of the device. Therefore, improvement is needed. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal device for steel structure processing, which has a good dust removal effect on the smoke and dust generated during steel structure processing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A dust removal device for steel structure processing includes a base plate, a fume hood, a main exhaust pipe, a side exhaust pipe, a branch pipe, a first turbine fan blade, and a second turbine fan blade. A flue is fixedly connected to the outside of the base plate. The main exhaust pipe extends into the interior of the flue. A placement box is fixedly connected to the upper surface of the base plate. A side suction hole is provided inside the placement box. One end of the branch pipe extends into the interior of the placement box, and the other end extends into the interior of the flue. A first motor is fixedly connected inside the placement box. The output end of a motor is fixedly connected to the first turbine blade. A square box is fixedly connected to the upper surface of the fume hood. A second motor is fixedly connected inside the square box. The output end of the second motor is fixedly connected to the second turbine blade. One end of the side exhaust pipe passes through the interior of the square box, and the other end of the side exhaust pipe passes through the interior of the main exhaust pipe. A top rod is fixedly connected to the exterior of the fume hood. A platform is fixedly connected to the exterior of the flue. A square base is fixedly connected to the exterior of the placement box. A cylinder is fixedly connected to the upper surface of the square base. A steel plate is placed on the upper surface of the placement box.

[0007] By adopting the above technical solution, after the worker places the steel plate on the upper surface of the two placement boxes, the cutting and welding will generate smoke and dust. At this time, the worker simultaneously starts the first motor and the second motor. The output end of the first motor drives the first turbine blade to rotate, and the output end of the second motor rotates with the second turbine blade. The rotating first turbine blade and the second turbine blade generate suction force inside the flue and the square box, respectively. The suction force generated in the flue draws the smoke and dust generated at the bottom and around the steel plate during processing into the main exhaust pipe for discharge through the branch pipe and side suction holes. At the same time, the smoke and dust generated on the upper surface of the steel plate during processing is drawn into the side exhaust pipe by the suction force generated inside the square box and the gathering effect of the fume hood. After passing through the side exhaust pipe, it is transported together into the main exhaust pipe for discharge. Through the above operation, the smoke and dust generated around the steel plate during processing are completely removed, achieving a good dust removal effect for the smoke and dust generated during steel structure processing.

[0008] A further feature of this invention is that a push rod is provided on the outer side of the square base, a cleaning cloth is attached to the bottom of the push rod, and the output end of the cylinder is fixedly connected to the push rod.

[0009] By adopting the above technical solution, before processing the steel plate, the worker starts the cylinder, which drives the push rod to reciprocate, so that the cleaning cloth wipes the surface of the steel plate and removes the floating dust.

[0010] A further feature of this invention is that a wire mesh is fixedly connected inside the side suction hole, and the wire mesh consists of two layers.

[0011] By adopting the above technical solution, the wire mesh prevents iron slag falling during steel plate cutting from falling into the side suction hole.

[0012] A further feature of this invention is that a collection box is provided on the upper surface of the base plate, and a pull bolt is fixedly connected to the outside of the collection box.

[0013] By adopting the above technical solution, the collection box facilitates the collection of iron slag that falls off during steel plate cutting.

[0014] A further feature of this invention is that the bottom plate has a groove inside, and the bottom of the collection box is provided with a pulley, which is slidably connected to the groove.

[0015] By adopting the above technical solution, the pulley and groove are slidably connected, making it easy for workers to pull the bolt to make the collection box move smoothly after it is full.

[0016] A further feature of this invention is that the exterior of the smoke hood is hinged with a curved frame, and a downlight is fixedly connected to the exterior of the curved frame.

[0017] By adopting the above technical solution, downlights are used to illuminate the steel plate during processing.

[0018] A further feature of this invention is that a cylinder is rotatably connected to the outside of the platform, and the other end of the top rod is fixedly connected to the cylinder.

[0019] By adopting the above technical solution, the rotating connection between the cylinder and the platform allows the top rod to rotate under force, making it easier to align the fume hood with the position where smoke and dust rise, thus improving the effect of smoke and dust removal on the upper surface of the steel plate.

[0020] A further feature of this invention is that the top rod is externally fixedly connected with two handles.

[0021] By adopting the above technical solution, the two handles make it easier for workers to pull the top rod to rotate the fume hood.

[0022] A further feature of this invention is that both the main exhaust pipe and the side exhaust pipe are fixedly connected with HEPA filter elements, and the number of HEPA filter elements is two.

[0023] By adopting the above technical solution, the dust and mist flowing from the main exhaust pipe and the side exhaust pipe are filtered simply by the action of the HEPA filter element before being discharged to the outside of the main exhaust pipe.

[0024] A further feature of this invention is that an mounting plate is fixedly connected to the outside of the main exhaust pipe, and the mounting plate has a threaded hole inside.

[0025] By adopting the above technical solution, workers use screws to fix the main exhaust pipe to the crossbeam of the workshop through the mounting plate and threaded holes.

[0026] The beneficial effects of this utility model are: 1. This utility model, through the coordinated arrangement of a base plate, fume hood, main exhaust pipe, side exhaust pipe, branch pipe, flue, placement box, side suction hole, first turbine blade, square box, second motor, top rod, platform, square base, cylinder, and steel plate, enables the device to handle the dust generated during steel plate cutting and welding. The first and second motors, through their operation, cause the rotating first and second turbine blades to generate suction within the flue and square box, respectively. The suction generated within the flue, through the branch pipe and side suction hole, draws the dust generated at the bottom and sides of the steel plate during processing into the main exhaust pipe for discharge. Simultaneously, the dust generated on the upper surface of the steel plate during processing is drawn into the side exhaust pipe by the suction generated inside the square box and then gathered by the fume hood. After passing through the side exhaust pipe, the dust is then transported together into the main exhaust pipe for discharge.

[0027] 2. This utility model, through the coordinated arrangement of the push rod, cleaning cloth, wire mesh, collection box, pull bolt, groove, pulley, bending frame, downlight, cylinder, handle, HEPA filter element, mounting plate, and threaded hole, enables the device to achieve reciprocating motion of the push rod driven by the cylinder during use. This allows the cleaning cloth to wipe the surface of the steel plate, removing surface dust. The wire mesh prevents iron slag falling during steel plate cutting from falling into the side suction hole. The collection box facilitates the collection of iron slag falling during steel plate cutting. The sliding connection between the pulley and the groove facilitates the filling of the collection box. Workers pull the lever to move the collection box smoothly. Downlights illuminate the steel plate processing. The rotating connection between the cylinder and the platform allows the top rod to rotate, making it easier to align the fume hood with the rising smoke and dust, thus improving the smoke and dust removal effect on the upper surface of the steel plate. Two handles allow workers to pull the top rod to rotate the fume hood. Dust and mist flowing from the main exhaust pipe and side exhaust pipes are filtered by the HEPA filter before being discharged to the outside of the main exhaust pipe. Through the mounting plate and threaded holes, workers use screws to fix the main exhaust pipe to the crossbeam of the workshop. Attached Figure Description

[0032] A dust removal device for steel structure processing includes the following embodiments: Example 1:

The outside of the placement box 7 is fixedly connected to a square base 14. The upper surface of the square base 14 is fixedly connected to a cylinder 15. A steel plate 16 is placed on the upper surface of the placement box 7. When cutting and welding steel plate 16, fumes are generated. Through the action of the first motor 8 and the second motor 11, the rotating first turbine blade 9 and the second turbine blade 10 generate suction in the flue 6 and the square box 32, respectively. The suction generated in the flue 6, through the action of the branch pipe 5 and the side suction hole 31, draws the fumes generated at the bottom and around the steel plate 16 during processing into the main exhaust pipe 3 for discharge. At the same time, the fumes generated on the upper surface of the steel plate 16 during processing are drawn into the side exhaust pipe 4 by the suction generated inside the square box 32 and the gathering effect of the fume hood 2. After passing through the side exhaust pipe 4, they are transported together into the main exhaust pipe 3 for discharge. Example 2:

[0034] Reference Figure 1-4 A push rod 17 is provided on one side of the square base 14. A cleaning cloth 18 is snapped into the bottom of the push rod 17. The output end of the cylinder 15 is fixedly connected to the push rod 17. A wire mesh 19 is fixedly connected inside the side suction hole 31. There are two layers of wire mesh 19. A collection box 20 is provided on the upper surface of the base plate 1. A pull bolt 21 is fixedly connected to the outside of the collection box 20. A groove 22 is opened inside the base plate 1. A pulley 23 is provided at the bottom of the collection box 20. The pulley 23 is slidably connected to the groove 22. The cylinder 15 drives the push rod 17 to reciprocate, causing the cleaning cloth 18 to wipe the surface of the steel plate 16, removing the floating dust. The wire mesh 19 prevents iron slag falling during the cutting of the steel plate 16 from falling into the side suction hole 31. The collection box 20 facilitates the collection of iron slag falling during the cutting of the steel plate 16. The pulley 23 is slidably connected to the groove 22, so that when the collection box 20 is full, the worker can pull the bolt 21 to make the collection box 20 move smoothly. Example 3:

[0035] Reference Figure 1-3 The external hinge of the smoke hood 2 is connected to a curved frame 24, and the external fixed connection of the curved frame 24 is a downlight 25. The external rotating connection of the platform 13 is a cylinder 26. The other end of the top rod 12 is fixedly connected to the cylinder 26. The external fixed connection of the top rod 12 is a handle 27, and there are two handles 27. The internal fixed connection of the main exhaust pipe 3 and the side exhaust pipe 4 is a HEPA filter element 28, and there are two HEPA filter elements 28. The external fixed connection of the main exhaust pipe 3 is a mounting plate 29, and the internal opening of the mounting plate 29 is a threaded hole 30. The downlight 25 illuminates the steel plate 16 during processing. The rotating connection between the cylinder 26 and the platform 13 allows the top rod 12 to rotate under force, making it easier to align the fume hood 2 with the rising smoke and dust, thus improving the smoke and dust removal effect on the upper surface of the steel plate 16. The two handles 27 allow workers to pull the top rod 12 to rotate the fume hood 2. The dust and mist flowing from the main exhaust pipe 3 and the side exhaust pipe 4 are filtered by the HEPA filter element 28 before being discharged to the outside of the main exhaust pipe 3. Through the mounting plate 29 and the threaded hole 30, the workers use screws to fix the main exhaust pipe 3 to the crossbeam of the workshop.

[0036] In this invention, when workers place the steel plate 16 on the upper surface of the two placement boxes 7 and cut and weld it, smoke and dust will be generated. At this time, the workers simultaneously start the first motor 8 and the second motor 11. The output end of the first motor 8 drives the first turbine blade 9 to rotate, while the output end of the second motor 11 rotates with the second turbine blade 10. The rotating first turbine blade 9 and the second turbine blade 10 generate suction force inside the flue 6 and the square box 32, respectively. The suction force generated in the flue 6 is used to draw out the dust through the branch pipe 5 and the side suction hole 31. During the processing of steel plate 16, the dust generated at the bottom and around its perimeter is drawn into the main exhaust pipe 3 for discharge. Simultaneously, the dust generated on the upper surface of steel plate 16 during processing is drawn into the side exhaust pipe 4 by the suction force generated inside the square box 32 and then by the gathering effect of the fume hood 2. After passing through the side exhaust pipe 4, it is transported together into the main exhaust pipe 3 for discharge. Through the above operations, the dust generated around steel plate 16 during processing is completely removed, achieving excellent dust removal efficiency during steel structure processing. This is achieved through cylinder 1. 5 drives the push rod 17 to reciprocate, causing the cleaning cloth 18 to wipe the surface of the steel plate 16, removing the floating dust. The wire mesh 19 prevents iron slag falling during the cutting of the steel plate 16 from falling into the side suction hole 31. The collection box 20 facilitates the collection of iron slag falling during the cutting of the steel plate 16. The pulley 23 is slidably connected to the groove 22, allowing the worker to pull the bolt 21 to move the collection box 20 smoothly after it is full. The downlight 25 provides illumination during the processing of the steel plate 16. The cylinder 26 and... The rotating connection of platform 13 allows the top rod 12 to rotate after being stressed, making it easier to align the fume hood 2 with the position where smoke and dust rise, thus improving the smoke and dust removal effect on the upper surface of steel plate 16. The two handles 27 make it easy for workers to pull the top rod 12 to rotate the fume hood 2. The dust and mist flowing from the main exhaust pipe 3 and the side exhaust pipe 4 are simply filtered by the HEPA filter element 28 before being discharged to the outside of the main exhaust pipe 3. Through the mounting plate 29 and the threaded hole 30, the workers use screws to fix the main exhaust pipe 3 to the crossbeam of the workshop.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
