Description

Technical Field

[0001] The invention belongs to the technical field of smoke purification, and in particular relates to a purification workshop with multiple purification functions. Background Art

[0002] During the welding process of parts, welding fumes with complex components are generated in the welding workshop, which contain metal elements such as iron, copper, nickel, chromium, as well as toxic and harmful substances such as lead and mercury. They are also mixed with gaseous pollutants such as nitrogen oxides, sulfur dioxide, and carbon dioxide. These fumes pose a serious threat to human health. Therefore, purification equipment needs to be installed in the welding workshop to form a purification workshop to purify the fumes generated by welding.

[0003] The purification equipment installed in the existing welding workshops mostly lays dust collection pipes on the top of the workshop, and centrally extracts the smoke generated by welding and transports it to the purification equipment outside the workshop for smoke purification treatment. Obviously, since there are many welding stations in the welding workshop, if a centralized extraction method is adopted, it is easy to cause the smoke generated by welding to generate turbulence inside the workshop, and then it is easy to cause dust and other debris in the smoke to adhere to the walls of the workshop, which will affect the purification effect of the smoke. At the same time, the purification equipment needs to generate a large output power to be able to extract and purify the smoke generated by welding in the welding workshop, which is easy to cause energy waste. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions:

The annular connecting plate includes connecting strips and arc plates. A plurality of the connecting strips are circumferentially arrayed and connected between the metal filter cylinder and the substrate. An arc plate is hermetically inserted between adjacent two of the connecting strips. The lower surface of the arc plate is connected to the output rod of the electric telescopic rod. The distance between adjacent two of the supporting strips is the same as the distance between adjacent two of the connecting strips, so that the arc plate moves downward between adjacent two of the supporting strips. The upper surface of the arc plate is designed as a slope surface.

[0009] In the technical solution of the present invention, a support ring is installed on the bottom of the metal filter cylinder in an insulating manner, and an annular support cavity is formed on the lower bottom surface of the support ring. A plurality of support long rods are vertically fixed on the upper pipe orifice of the central conduit, and the plurality of support long rods correspond to the plurality of supporting strips. The top ends of the plurality of support long rods are inserted into the annular support cavity. The flange on the outer circumferential surface of the dust collection hood is bolted to the flange on the outer circumferential surface of the purification box. A plurality of the connecting strips are connected to the inner circumferential surface of the support ring.

[0010] In the technical solution of the present invention, an annular collection box is installed on the upper surface of the dust collection hood, and the box orifice of the annular collection box is aligned with the bottom of the purification box. A flange is provided at the outer box orifice of the annular collection box, and its inner box orifice is attached to the pipe wall of the central conduit. A suction pipe is connected and installed on the side wall of the bottom of the annular collection box.

[0011] In the technical solution of the present invention, a T-shaped slot is vertically opened inside the purification box, and a T-shaped insert is installed on the back of the brush plate away from the metal filter cylinder. The T-shaped insert is slidably inserted into the T-shaped slot, and the bottom of the T-shaped insert is connected to the outer box mouth wall of the annular collection box.

[0012] In the technical solution of the present invention, a plurality of spring parts are installed on the top of the purification box, and the plurality of spring parts are in conflict with the upper plate body of the brush plate installed on the inner wall of the purification box.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention can intercept and separate the metal and non-metallic particles in the welding fume through the design of the metal filter cylinder and the dust filter cylinder in the purification box, and prevent the metal particles from damaging or clogging the filter cylinder of the non-metallic material, and at the same time can adsorb and purify the harmful substances in the fume. Moreover, since the purification box is adjustable and arranged above the welding workbench, the fume generated by welding can be directly collected and purified at a close distance, and the pipeline will not be blocked due to the collected fume flowing in the pipeline for too long. In addition, the phenomenon of energy waste in the welding workshop caused by the relatively scattered fume generated by welding can be reduced.

[0016] 2. The present invention can not only scrape and clean the metal dust or particulate matter adhered to the outer surface of the metal filter cylinder through the rotating metal filter cylinder by the stationary installed brush plate, but also drive the brush plate on the inner wall to scrape and clean the non-metallic dust or particulate matter adhered to the surface of the dust filter cylinder through its own rotation. The dust scraped off the surface of the dust filter cylinder can be discharged to the outside through the opened cavity bottom, preventing the scraped dust particles from accumulating between the dust filter cylinder and the metal filter cylinder. When the multiple curved plates slide upward into the gaps between the connecting strips, the cooperation of the multiple curved plates and the multiple connecting strips can seal the bottom of the metal filter cylinder and the dust filter cylinder, so that the metal filter cylinder and the dust filter cylinder continue to purify the welding fume.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0035] Please refer to Figures 1 - 3 As shown, the present invention is a purification workshop with multiple purification functions, including a telescopic arm 1. The telescopic arm 1 is placed on the wall of the welding workshop. A purification box 2 is connected to the telescopic arm 1. A dust collection hood 3 is communicated with the bottom of the purification box 2. A soot purification mechanism 4 is arranged inside the purification box 2. The soot purification mechanism 4 includes a metal filter cartridge 41, a dust filter cartridge 42, a filter element 43, and a dust suction pipe 44. A metal filter cartridge 41 is installed in the purification box 2, and an electromagnetic suction strip 45 is arranged on the barrel wall of the metal filter cartridge 41. A dust filter cartridge 42 is hermetically inserted into the metal filter cartridge 41. The barrel wall of the metal filter cartridge 41 and the barrel wall of the dust filter cartridge 42 are installed without contact. A filter element 43 is arranged inside the dust filter cartridge 42. A dust suction pipe 44 is communicated with the top of the purification box 2, and the pipe orifice of the dust suction pipe 44 is aligned with the barrel orifice of the dust filter cartridge 42. The upper pipe orifice of the dust suction pipe 44 is communicated with a suction pipe through a connecting hose 49.

[0036] Specifically, the present invention installs the purification box 2 on the wall of the welding workshop through the telescopic arm 1, so that the dust collection hood 3 at the bottom of the purification box 2 is suspended above the welding station. Then, the blower system outside the welding workshop is started, and the suction force generated by it acts on the purification box 2 through the suction pipe, the connecting hose 49 and the dust suction pipe 44. Then, the welding fumes are sucked into the purification box 2 through the dust collection hood 3. The incoming fumes will first pass through the metal filter cartridge 41 for filtration and interception. At this time, the electromagnetic suction strips 45 installed in a circumferential array will be energized, so that the metal filter cartridge 41 has a magnetic adsorption force. Furthermore, the dust mixed with metal components in the fumes will be adsorbed, filtered and intercepted and connected to the outside of the metal filter cartridge 41. The dust or particles of other non-metal components mixed in the fumes will be filtered and intercepted by the internal dust filter cartridge 42, so as to effectively intercept and filter the dust or particles mixed in the fumes. The intercepted fumes will enter the filter element 43, and the filter element 43 is preferably one of activated carbon materials, polyester fibers or glass fibers, so as to adsorb and filter the harmful gases in the fumes. Furthermore, through the design of the metal filter cartridge 41 and the dust filter cartridge 42 in the purification box 2, not only can the metal and non-metal particles in the welding fumes be intercepted and separated, preventing the metal particles from damaging or blocking the filter cartridges made of non-metal materials, but also the harmful substances in the fumes can be adsorbed, purified and separated. Moreover, since the purification box 2 is adjustably arranged above the welding workbench, the welding fumes generated can be directly collected, purified and treated in a concentrated manner at a short distance, without causing the phenomenon of pipeline blockage due to the too long flow time of the collected fumes in the pipeline, and it can also reduce the phenomenon of energy waste caused by the relatively dispersed welding fumes in the welding workshop.

[0037] Please refer to Figures 3 - 5As shown, a scraping and cleaning mechanism 5 is provided inside the purification box 2. The scraping and cleaning mechanism 5 includes an insulating ring 51, a brush plate 52, a support strip 53, a support bottom plate 54, a substrate 55, and an annular connecting plate 56. The insulating ring 51 is installed on the inner top of the purification box 2. An annular cavity is opened on the lower surface of the insulating ring 51. A metal filter cylinder 41 is rotatably inserted into the annular cavity. A plurality of brush plates 52 are installed on the box wall of the purification box 2, and the brushes on the plurality of brush plates 52 are in contact with the outer wall of the metal filter cylinder 41. The diameter of the central conduit 31 of the dust collection hood 3 is the same as the diameter of the metal filter cylinder 41. A flow cavity is formed between the upper pipe orifice of the central conduit 31 and the bottom of the metal filter cylinder 41. A plurality of support strips 53 are installed on the inner wall of the upper orifice of the central conduit 31, and the plurality of support strips 53 are connected to a support bottom plate 54 located at the center of the central conduit 31. A servo motor is arranged on the upper surface of the support bottom plate 54, and a substrate 55 is fixed on the output shaft of the servo motor. The top end of the output shaft is connected to the bottom of the dust filter cylinder 42 through a bearing. The outer circumferential surface of the substrate 55 is connected to the bottom of the metal filter cylinder 41 through an annular connecting plate 56;

[0038] Specifically, the welding fumes will flow upward through the central conduit 31 of the dust collection hood 3, and then enter the filter chamber formed between the outer wall of the purification box 2 and the metal filter cartridge 41 through multiple flow chambers formed between the top of the central conduit 31 and the bottom of the metal filter cartridge 41 to perform a large-area filtering and interception treatment on the particles or dust debris in the fumes. The support bottom plate 54 with a convex lower surface is located at the center of the central conduit 31 and is connected to the pipe wall of the central conduit 31 through four support strips 53, so that it will not affect the passage of the welding fumes through the central conduit 31 into the interior of the purification box 2, and can also disperse and diffuse the flowing fumes, preventing the fumes from directly hitting the bottom of the metal filter cartridge 41 or the dust filter cartridge 42. When it is necessary to clean the soot particles magnetically adsorbed on the surface of the metal filter cartridge 41 used for long-term filtration, at this time, the soot purification mechanism 4 connected to the purification box 2 stops working, and the electromagnetic suction strip 45 installed on the metal filter cartridge 41 is powered off to lose its magnetic adsorption force. Then, the servo motor fixed on the upper surface of the support bottom plate 54 is controlled to work, so that it drives the metal filter cartridge 41 inserted into the insulating ring 51 to rotate through the substrate 55 and the annular connecting plate 56. Since at least four brush plates 52 are vertically fixed on the inner wall of the purification box 2 in a circumferential array, the rotation of the metal filter cartridge 41 can contact the brush strips on the surface of the relatively static brush plates 52, thereby being able to scrape and clean the metal particles or dust adhered and intercepted on the surface of the metal filter cartridge 41, and falling into the collection chamber formed between the central conduit 31 and the bottom of the purification box 2, preventing the phenomenon of blockage caused by too many particles or dust filtered, intercepted and adhered on the surface of the metal filter cartridge 41. At the same time, the rotating metal filter cartridge 41 will generate a certain centrifugal force, which is convenient for accelerating the rapid cleaning of the particles or dust intercepted and adhered on its surface. <> <>

[0039] Please refer to <> Figures 1 - 5As shown, the scraping and cleaning mechanism 5 further includes a bottom support block 57 and an electric telescopic rod 58. A bottom support block 57 is fixed to the lower surface of each support strip 53, and the width of the bottom support block 57 is greater than the width of the support strip 53. An electric telescopic rod 58 is vertically installed on the bottom support block 57, and the electric telescopic rod 58 is arranged in a dislocation manner with the support strip 53. A plurality of brush plates 52 are installed on the inner cylindrical wall of the metal filter cylinder 41, and the brushes of the brush plates 52 are in contact with the outer cylindrical wall of the dust filter cylinder 42. The annular connecting plate 56 includes a connecting strip 561 and an arc plate 562. A plurality of the connecting strips 561 are circumferentially arrayed and connected between the metal filter cylinder and the substrate 55, and an arc plate 562 is hermetically inserted between two adjacent connecting strips 561. The lower surface of the arc plate 562 is connected to the output rod of the electric telescopic rod 58. The distance between two adjacent support strips 53 is the same as the distance between two adjacent connecting strips 561, so that the arc plate 562 moves downward between two adjacent support strips 53. The upper surface of the arc plate 562 is designed as a slope surface;

[0040] Specifically, when the soot purification mechanism 4 stops working and it is necessary to clean the dust or particulate matter adhering to the surfaces of the metal filter cartridge 41 and the dust filter cartridge 42, the magnetic force first needs to control the output rods of at least four electric telescopic rods 58 vertically fixed on the bottom support blocks 57 to retract, so that they drive the four arc-shaped plates 562 to move downward and disengage from between two adjacent connecting strips 561. The four arc-shaped plates 562 moving downward synchronously will slide downward and insert between two adjacent support strips 53. The mutual insertion and cooperation of the four arc-shaped plates 562 and the four support strips 53 can block the upper pipe orifice of the central conduit 31. Moreover, as the four arc-shaped plates 562 slide downward from the bottom of the metal filter cartridge 41, they can also open the bottom of the filtering cavity formed between the metal filter cartridge 41 and the dust filter cartridge 42. Then, when the metal filter cartridge 41 rotates and the dust or particulate matter adhering to its outer surface is scraped and cleaned by the bristles of the multiple stationary brush plates 52, at the same time, the bristles of the four brush plates 52 vertically and insulatingly arranged in a circular array on the inner circumferential surface of the metal filter cartridge 41 will also scrape and clean the non-metal particles or dust debris adhering to the surface of the dust filter cartridge 42 in a rotating state. The dust or particulate matter scraped from the surface of the dust filter cartridge 42 will fall onto the upper surfaces of the multiple sealed arc-shaped plates 562 through the opened filtering cavity at the bottom. Since the upper surfaces of the multiple arc-shaped plates 562 are designed as inclined planes, the falling non-metal dust or particulate matter will slide into the collection cavity formed between the purification box 2 and the central conduit 31 for collection operations, and it can also prevent the phenomenon of blockage due to excessive dust and particulate matter adhering to the surface of the dust filter cartridge 42. When the scraping and cleaning of the dust or particulate matter adhering to the surfaces of the metal filter cartridge 41 and the dust filter cartridge 42 are completed, at this time, the output rods of the multiple electric telescopic rods 58 extend, driving the multiple arc-shaped plates 562 to slide upward to between the two connecting strips 561, achieving the blockage of the bottom between the metal filter cartridge 41 and the dust filter cartridge 42. At this time, the upper pipe orifice of the central conduit 31 will be opened, enabling the soot purification mechanism 4 in the purification box 2 to continue working to purify the welding fumes. Furthermore, the rotating metal filter cartridge 41 can not only scrape and clean the metal dust or particulate matter filtered and adhered to its outer surface by the stationary brush plates 52, but also drive the brush plates 52 on its inner wall surface to scrape and clean the non-metal dust or particulate matter adhering to the surface of the dust filter cartridge 42 through its own rotation. The dust scraped from the surface of the dust filter cartridge 42 can be discharged to the outside through the opened bottom, preventing the phenomenon of accumulation of the scraped dust and particulate matter between the dust filter cartridge 42 and the metal filter cartridge 41. When the multiple arc-shaped plates 562 slide upward into the gaps between the connecting strips 561, at this time, the cooperation of the multiple arc-shaped plates 562 and the multiple connecting strips 561 can also block the bottom between the metal filter cartridge 41 and the dust filter cartridge 42, enabling the metal filter cartridge 41 and the dust filter cartridge 42 to continue purifying the welding fumes.

[0041] Please refer to Figures 5 - 6 As shown, a support ring 46 is installed on the bottom of the metal filter screen cylinder 41 in an insulating manner, and an annular support cavity 461 is formed on the lower bottom surface of the support ring 46. A plurality of support long rods 47 are vertically fixed to the upper pipe orifice of the central conduit 31, and the plurality of support long rods 47 correspond to the plurality of support strips 53. The top ends of the plurality of support long rods 47 are inserted into the annular support cavity 461. The flange 6 on the outer circumferential surface of the dust collection hood 3 and the flange 6 on the outer circumferential surface of the purification box 2 are connected by bolts. The plurality of connecting strips 561 are connected to the inner circumferential surface of the support ring 46;

[0042] Specifically, when it is necessary to disassemble and repair the metal filter screen cylinder 41, the dust filter screen cylinder 42 and the filter element 43 that have been used for a long time, at this time, the flange 6 on the dust collection hood 3 and the flange 6 on the purification box 2 are disassembled, and then the dust collection hood 3 is pulled downward. At this time, the central conduit 31 will drive the support bottom plate 54 to move downward through the support strip 53, and then the metal filter screen cylinder 41, the dust filter screen cylinder 42 and the filter element 43 will be removed from the purification box 2; when the structures such as the metal filter screen cylinder 41 are inserted upward into the purification box 2, at this time, the top end of the metal filter screen cylinder 41 will be inserted into the annular cavity of the insulating ring 51, and the four support long rods 47 at the upper pipe orifice of the central conduit 31 are inserted into the annular support cavity 461, which will support the metal filter screen cylinder 41 by gravity, preventing the metal filter screen cylinder 41 from being connected to the substrate 55 only through the four connecting strips 561 at the bottom, resulting in the phenomenon of the metal filter screen cylinder 41 sagging, which will affect the normal filtering and interception of the welding fume by the metal filter screen cylinder 41. The plurality of support long rods 47 are rotationally inserted into the annular support cavity 461, so that it will not affect the normal rotation of the metal filter screen cylinder 41, and it corresponds to the support strip 53, so the blocking effect on the fume entering the purification box 2 can be reduced.

[0043] Please refer to Figure 3 and Figure 4As shown, an annular collecting box 7 is installed on the upper surface of the dust collecting hood 3, and the box opening of the annular collecting box 7 is aligned with the box bottom of the purification box 2, the outer box opening of the annular collecting box 7 is provided with a flange 6, and its inner box opening is in contact with the pipe wall of the central duct 31, and the box bottom side wall of the annular collecting box 7 is connected and a suction pipe is installed; specifically, when the metal filter cylinder 41 is in a state of self-rotation, the metal dust or particles adhered to its surface are scraped off by the brush on the fixed brush plate 52. At this time, the dust or particles will The dust or particles scraped off from the surface of the dust filter cylinder 42 will fall into the annular collection box 7. At the same time, the non-metallic dust or particles scraped off from the surface of the dust filter cylinder 42 will also be discharged into the annular collection box 7 through the bottom of the cavity opened below. At this time, the suction pipe on the annular collection box 7 can be connected to the dust suction pipe 44 of the vacuum cleaner to generate a suction force that can quickly suck out the scraped metal dust or particles. When the dust hood 3 is disassembled, the annular collection box 7 will also be disassembled synchronously, which makes it easier to clean the dust or particles adhering to the surface of the annular collection box 7.

[0044] See also Figures 3 - 5 As shown, a T-shaped slot is vertically opened inside the purification box 2, and a T-shaped insert 59 is installed on the back of the brush plate 52 away from the metal filter cylinder 41. The T-shaped insert 59 is slidably inserted into the T-shaped slot, and the bottom of the T-shaped insert 59 is connected to the outer box mouth wall of the annular collection box 7; specifically, when the annular collection box 7 is disassembled, the T-shaped insert 59 will be pulled out from the T-shaped slot, which makes it convenient to pull out and disassemble the brush plate 52 from the inner wall of the purification box 2, and to facilitate the removal and replacement of damaged brushes on the brush plate 52. The brush plate 52 will not rotate in the purification box 2 through the mutual disassembly and cooperation of the T-shaped insert 59 and the T-shaped slot.

[0045] See also Figures 3 - 5 As shown, a plurality of spring members 8 are installed on the top of the purification box 2, and the plurality of spring members 8 are in conflict with the upper plate body of the brush plate 52 installed on the inner wall of the purification box 2. An elastic strip 81 is vertically connected to one side of the bottom of each of the spring members 8. The elastic strip 81 is located on the brush side of the brush plate 52, and the bottom end of the elastic strip 81 extends to the bottom of the brush plate 52. The outer ring surface of the support ring 46 is connected to a plurality of toggle rods 48, and the plurality of toggle plates are respectively in contact with the plurality of elastic strips 81.

[0046] Specifically, a plurality of the spring members 8 are vertically installed in the filtering cavity formed between the outer circumferential surface of the metal filter cartridge 41 and the inner wall of the purification tank 2. Therefore, when the metal filter cartridge 41 rotates and its outer circumferential surface contacts the bristles on the bristle plate 52 to scrape and clean the metal dust or particles adhered to its outer circumferential surface, at this time, a plurality of toggle rods 48 on the outer circumferential surface of the support ring 46 will rotate synchronously and contact the bottom end of the elastic strip 81 made of elastic metal. At this time, the toggle rod 48 will generate a rotational thrust on the elastic strip 81, causing the elastic strip 81 to be toggled and bent. Therefore, when the toggle rod 48 reciprocally toggles or disengages from the elastic strip 81, at this time, the spring member 8 will drive the elastic strip 81 to vibrate the bristles on the bristle plate 52, so that the dust or particles scraped and adhered to the surface of the bristles quickly fall off. And when the bristle plate 52 is disassembled from the inner wall of the purification tank 2, at this time, the spring thrust of the spring member 8 will push the bristle plate 52 downward, so that the T-shaped insert 59 can be stably pushed out from the T-shaped slot, preventing the T-shaped insert 59 from being too tightly engaged in the T-shaped slot and making it difficult to disassemble.
