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] When welding parts in a welding workshop, welding fumes with complex components will be generated, including metal elements such as iron, copper, nickel, chromium, and 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, it is necessary to install purification equipment in the welding workshop to form a purification workshop to purify the fumes generated by welding.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional 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 therefore should not be understood as limiting the present invention.

[0035] See also Figure 1-Figure 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, the telescopic arm 1 is connected to a purification box 2, and the bottom of the purification box 2 is connected to a dust collecting hood 3, the purification box 2 is built with a smoke purification mechanism 4, the smoke purification mechanism 4 includes a metal filter cylinder 41, a dust filter cylinder 42, a filter element 43 and a dust suction pipe 44, the purification box 2 is installed with a metal filter cylinder 41, and the An electromagnetic suction strip 45 is provided on the wall of the metal filter cylinder 41, a dust filter cylinder 42 is sealed and plugged into the metal filter cylinder 41, the cylinder wall of the metal filter cylinder 41 and the cylinder wall of the dust filter cylinder 42 are non-contact mounted, a filter element 43 is provided in the dust filter cylinder 42, a dust suction pipe 44 is connected to the top of the purification box 2, and the pipe opening of the dust suction pipe 44 is aligned with the pipe opening of the dust filter cylinder 42; the upper pipe opening of the dust suction pipe 44 is connected to the 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 collecting hood 3 at the bottom of the purification box 2 is suspended above the welding station, and then the fan system outside the welding workshop is started to generate a suction force that acts on the purification box 2 through the suction pipe, the connecting hose 49 and the dust suction pipe 44, and then the smoke generated by the welding is sucked into the purification box 2 through the dust collecting hood 3, and the incoming smoke will first pass through the metal filter cylinder 41 for filtering and interception, and at this time, the electromagnetic suction strips 45 installed in the circumferential array will be energized, so that the metal filter cylinder 41 has a magnetic adsorption force, and then the dust mixed with the metal components in the smoke will be adsorbed, filtered and intercepted to the outside of the metal filter cylinder 41, and the dust or particulate matter of other non-metallic components mixed in the smoke will be filtered and intercepted through the internal dust filter cylinder 42, so that it can effectively intercept the dust or particulate matter mixed in the smoke. The smoke is filtered, and the intercepted smoke will enter the filter element 43, and the filter element 43 is preferably one of activated carbon materials, polyester fiber or glass fiber, so as to achieve adsorption and filtration of harmful gases in the smoke. Then, through the design of the metal filter cylinder 41 and the dust filter cylinder 42 in the purification box 2, it is possible to intercept and separate the metal and non-metal particles in the welding smoke, and prevent the metal particles from damaging or clogging the filter cylinder of the non-metal material, and at the same time, it is possible to adsorb, purify and separate the harmful substances in the smoke. Moreover, since the purification box 2 is adjustable and arranged above the welding workbench, the smoke generated by welding can be directly collected and purified at a close distance, and the pipeline will not be blocked due to the collected smoke flowing in the pipeline for too long, and the energy waste caused by the relatively scattered smoke generated by welding in the welding workshop can be reduced.

[0037] See also Figure 3-Figure 5As shown, a scraping and cleaning mechanism 5 is provided in the purification box 2, and the scraping and cleaning mechanism 5 includes an insulating ring 51, a brush plate 52, a supporting strip 53, a supporting bottom plate 54, a base plate 55 and an annular connecting plate 56. An insulating ring 51 is installed on the inner top of the purification box 2, and an annular cavity is opened on the lower surface of the insulating ring 51. A metal filter cylinder 41 is rotatably inserted in 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 mesh wall of the metal filter cylinder 41. The diameter of the central conduit 31 of the dust collecting cover 3 is the same as that of the metal filter cylinder. 41, a flow cavity is formed between the upper pipe opening 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 hole pipe opening 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 base plate 55 is fixed on the output shaft of the servo motor, and the top end of the output shaft is connected to the bottom of the dust filter cylinder 42 through a bearing, and the outer ring surface of the base plate 55 is connected to the bottom of the metal filter cylinder 41 through an annular connecting plate 56;

[0038] Specifically, the smoke generated by welding will flow upward through the central duct 31 of the dust collecting hood 3, and then disperse into the filter cavity formed between the purification box 2 and the outer wall of the metal filter cylinder 41 through multiple flow cavities formed between the top of the central duct 31 and the bottom of the metal filter cylinder 41 to filter and intercept particles or dust debris in the smoke over a large area. The support bottom plate 54 with a convex lower surface is located at the center of the central duct 31, and is connected to the wall of the central duct 31 through four support strips 53, so that it will not affect the welding smoke from passing through the central duct 31 toward the inside of the purification box 2, and can also diffuse and disperse the flowing smoke, so that the smoke will not directly hit the bottom of the metal filter cylinder 41 or the dust filter cylinder 42. When it is necessary to clean the smoke particles magnetically adsorbed on the surface of the metal filter cylinder 41 used for long-term filtering, the smoke purification mechanism 4 connected to the purification box 2 is stopped at this time. The electromagnetic suction strip 45 installed on the metal filter cylinder 41 is powered off to make it lose its magnetic adsorption force, and then the servo motor fixed on the upper surface of the support base plate 54 is controlled to work, so that it drives the metal filter cylinder 41 inserted into the insulating ring 51 to rotate through the base plate 55 and the annular connecting plate 56. Since at least four brush plates 52 are in a circular array and vertically fixed on the inner wall of the purification box 2, the rotation of the metal filter cylinder 41 can contact the brush strips on the surface of the relatively stationary brush plate 52, so that the metal particles or dust adhered to the surface of the metal filter cylinder 41 can be scraped and cleaned, and fall into the collection chamber formed between the central duct 31 and the bottom of the purification box 2, to prevent the metal filter cylinder 41 from filtering and intercepting a large number of adhered particles or dust and causing blockage. At the same time, the rotating metal filter cylinder 41 will generate a certain centrifugal force by itself, so as to facilitate the rapid cleaning of the particles or dust intercepted and adhered on its surface.

[0039] See also Figure 1-Figure 5As shown, the scraping and cleaning mechanism 5 also includes a bottom support block 57 and an electric telescopic rod 58. The lower surface of each of the supporting strips 53 is fixed with a bottom support block 57, and the width of the bottom support block 57 is greater than the width of the supporting strip 53. The electric telescopic rod 58 is vertically installed on the bottom support block 57, and the electric telescopic rod 58 is staggered with the supporting strip 53. The inner cylinder wall of the metal filter cylinder 41 is installed with a plurality of brush plates 52, and the brushes of the brush plates 52 are in contact with the outer cylinder wall of the dust filter cylinder 42. The annular connecting plate 56 includes a connecting long Strip 561 and arc plate 562, a plurality of said connecting strips 561 are connected in a circular array between the metal filter cartridge and the base plate 55, an arc plate 562 is sealed and plugged between two adjacent connecting strips 561, the lower surface of said arc plate 562 is connected to the output rod of the electric telescopic rod 58, the distance between two adjacent supporting strips 53 is the same as the distance between two adjacent connecting strips 561, so that said arc plate 562 moves downward to between two adjacent supporting strips 53, and the upper surface of said arc plate 562 is designed as a slope surface;

[0040] Specifically, when the smoke purification mechanism 4 stops working and needs to clean the dust or particulate matter adhered to the surface of the metal filter cylinder 41 and the dust filter cylinder 42, the magnetism needs to first control the output rod of the vertically fixed electric telescopic rod 58 on at least four bottom support blocks 57 to be retracted, so that it drives the four arc plates 562 to disengage from between the two adjacent connecting strips 561 and move downward, and the four arc plates 562 moving downward synchronously will slide down and be inserted between the two adjacent supporting strips 53, so that the four arc plates 562 and the four supporting strips 53 are plugged into each other, which can block the upper pipe opening of the central duct 31, and the four arc plates 562 can slide downward from the bottom of the metal filter cylinder 41, and the metal filter cylinder 41 and the dust filter cylinder 4 can be connected. 2, the bottom of the filter cavity formed between the metal filter cylinder 41 is opened, and then when the metal filter cylinder 41 rotates, the dust or particles adhered to its outer surface are scraped and cleaned by the brushes on the stationary multiple brush plates 52, and at the same time, the upper brushes of the four brush plates 52 installed in the vertical insulating circumferential array on the inner ring surface of the metal filter cylinder 41 will also scrape and clean the non-metallic particles or dust debris adhered to and intercepted on the surface of the dust filter cylinder 42 in the rotating state, and the dust or particles scraped off the surface of the dust filter cylinder 42 will fall to the upper surface of the multiple sealed arc plates 562 through the filter cavity opened at the bottom, and because the upper surfaces of the multiple arc plates 562 are designed as slope surfaces, the falling non-metallic dust or particles will slide between the purification box 2 and the central conduit 31 The dust filter 41 is a kind of dust filter which is used for cleaning the surfaces of the metal filter 41 and the dust filter 42. The dust filter 41 is a kind of dust filter which is used for cleaning the surfaces of the metal filter 41 and the dust filter 42. The dust filter 41 is a kind of dust filter which is used for cleaning the surfaces of the metal filter 41 and the dust filter 42. The dust or particles can be scraped and cleaned, and at the same time, the brush plate 52 on the inner wall can be driven by its own rotation to scrape and clean the non-metallic dust or particles adhered to the surface of the dust filter cylinder 42, and the dust scraped from the surface of the dust filter cylinder 42 can be discharged to the outside through the opened cavity bottom, preventing the scraped dust particles from gathering between the dust filter cylinder 42 and the metal filter cylinder 41. When the multiple arc plates 562 slide upward into the gap between the connecting strips 561, the cooperation of the multiple arc plates 562 and the multiple connecting strips 561 can seal the bottom of the metal filter cylinder 41 and the dust filter cylinder 42, so that the metal filter cylinder 41 and the dust filter cylinder 42 continue to purify the welding smoke.

[0041] See also Figure 5-Figure 6 As shown, the bottom of the metal filter cylinder 41 is insulated and equipped with a support ring 46, and the lower bottom surface of the support ring 46 is provided with an annular support cavity 461, and the upper pipe opening of the central conduit 31 is vertically fixed with a plurality of support long rods 47, and the plurality of support long rods 47 correspond to the plurality of support long strips 53, and the top ends of the plurality of support long rods 47 are inserted into the annular support cavity 461, the flange 6 of the outer ring surface of the dust collecting cover 3 is connected to the flange 6 of the outer ring surface of the purification box 2 by bolts, and the plurality of connecting strips 561 are connected to the inner ring surface of the support ring 46;

[0042] Specifically, when it is necessary to disassemble and repair the metal filter cylinder 41, the dust filter cylinder 42 and the filter element 43 that have been used for a long time, the flange 6 on the dust hood 3 and the flange 6 on the purification box 2 are removed, and then the dust hood 3 is pulled downward. At this time, the central duct 31 will drive the supporting bottom plate 54 to move downward through the supporting strip 53, and then the metal filter cylinder 41, the dust filter cylinder 42 and the filter element 43 will be removed from the purification box 2; and when the metal filter cylinder 41 and other structures are inserted upward into the purification box 2, the top end of the metal filter cylinder 41 will be inserted into the annular cavity of the insulating ring 51, and the central duct 31 will be inserted into the annular cavity of the insulating ring 51. The four supporting long rods 47 at the upper pipe mouth are inserted into the annular supporting cavity 461, which will provide gravity support for the metal filter cylinder 41, preventing the metal filter cylinder 41 from being connected to the base plate 55 only through the four connecting strips 561 at the bottom, which will cause the metal filter cylinder 41 to fall, thereby affecting the normal filtering and intercepting treatment of welding smoke by the metal filter cylinder 41. The multiple supporting long rods 47 are rotatably inserted into the annular supporting cavity 461, so that they will not affect the normal rotation of the metal filter cylinder 41, and they correspond to the supporting strips 53, so they can reduce the blocking effect on smoke entering the purification box 2.

[0043] See also 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 adhering to its surface are scraped off by the brush on the fixed brush plate 52, and the dust or particles will The annular collection box 7 is provided with a dust collecting hood 3.

The dust collecting hood 3 is provided with a dust collecting hood 48. The dust collecting hood 3 is provided with a dust collecting hood 49.

[0044] See also Figure 3-Figure 5 As shown, a T-shaped slot is vertically opened inside the purification box 2, and a T-shaped strip 59 is installed on the back of the brush plate 52 away from the metal filter cylinder 41. The T-shaped strip 59 is slidably inserted into the T-shaped slot, and the bottom of the T-shaped strip 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 strip 59 will be pulled out of the T-shaped slot, which makes it convenient to pull the brush plate 52 out of the inner wall of the purification box 2 for disassembly, and to disassemble and replace the damaged brush on the brush plate 52. The brush plate 52 will not rotate in the purification box 2 through the mutual disassembly cooperation of the T-shaped strip 59 and the T-shaped slot.

[0045] See also Figure 3-Figure 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, and an elastic strip 81 is vertically connected to one side of the bottom of each of the spring members 8, and 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, and 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, the plurality of spring members 8 are vertically mounted in the filter cavity formed between the outer ring surface of the metal filter cylinder 41 and the inner wall of the purification box 2. Therefore, when the metal filter cylinder 41 rotates, the outer ring surface of the metal filter cylinder 41 contacts the brush on the brush plate 52, and the metal dust or particles adhering to the outer ring surface are scraped and cleaned. At this time, the plurality of toggle rods 48 on the outer ring surface of the support ring 46 will rotate synchronously and contact the bottom end of the elastic strip 81 made of elastic metal material. At this time, the toggle rod 48 will generate a rotational thrust on the elastic strip 81, so that the elastic strip 81 will generate a toggle Bending, therefore, when the toggle rod 48 reciprocates to toggle or disengage the elastic strip 81, the spring member 8 will drive the elastic strip 81 to vibrate the brush on the brush plate 52, so that the dust or particles adhering to the surface of the brush are scraped off and quickly fall off. When the brush plate 52 is removed from the inner wall of the purification box 2, the spring thrust of the spring member 8 will push the brush plate 52 downward, so that the T-shaped insert 59 can be stably pushed out of the T-shaped slot, preventing the T-shaped insert 59 from being too tightly engaged in the T-shaped slot, making it difficult to remove.
