Description

Technical Field

[0001] This utility model relates to the field of welding fume extraction machine technology, and more specifically, to a quick-release filter assembly for an industrial welding purification fume extraction machine. Background Technology

[0002] Industrial welding fume extractors are devices specifically designed to remove fumes and toxic gases generated during welding processes. They primarily utilize a multi-stage filtration system to remove welding fumes. Welding exhaust gases are first drawn into the purifier by a negative pressure fan, where large particles are filtered and deposited by the pre-filter. Subsequently, finer fumes and exhaust gases are further filtered and decomposed by a high-efficiency filtration device.

[0003] The working principle of existing industrial welding fume extraction machines' filter components is mainly based on physical filtration and adsorption. When welding fumes pass through the filter components, particulate matter and harmful gases are captured and adsorbed onto the surface of the filter material. Therefore, regular replacement is necessary.

[0004] Currently, replacing the filter components requires disassembling the purifier and removing the filter components for replacement. This process is cumbersome, and the sealing performance is easily affected by improper installation, leading to a decrease in filtration efficiency. Furthermore, since different filter components filter different products and have different filtration cycles, their replacement intervals also vary. Replacing a single filter component can easily damage the filtration effect of other filter components, and may even cause some harmful filtered substances to leak out of the purifier and be discharged, which has certain limitations.

[0005] Therefore, existing industrial welding purification fume extractors cannot quickly replace filter components, nor can they guarantee the safety of the replaced filter. Utility Model Content

[0006] The purpose of this application is to provide a quick-release filter assembly for an industrial welding purification fume extractor, which solves the technical problem of quickly replacing the filter assembly and ensuring filtration safety during the replacement process.

[0023] In this invention, a baffle pipe is installed to block the high-temperature welding particles brought in by the welding fumes when the smoke extraction pipe is sucked in, thus preventing them from entering the filtration space and damaging the filtration components.

[0035] EMBODIMENT

[0036] The industrial welding purification smoke extractor is generally composed of a machine box 1, a smoke pipe 2, a fan 3, a purification box 4 and a filter assembly 5. The machine box 1 is provided with the smoke pipe 2 which can be freely extended and bent at the top. The machine box 1 is internally provided with the purification box 4. The purification box 4 is internally provided with the filter assembly 5. The fan 3 is connected to the bottom of the purification box 4. The purification box 4 is connected to the smoke pipe 2 at the top. When the fan 3 is started, the smoke generated during welding can be sucked into the purification box 4 for filtration and then discharged.

[0037] Please refer to Figures 1-8 The utility model discloses a quick detachable filter assembly 5 of industrial welding purification fume extractor on the basis of the existing industrial welding purification fume extractor equipment, which comprises a purification box 4, a filter assembly 5, a material blocking pipe 6, a pulling assembly 7, a slag separating layer 8 and a slag assembly.

[0038] Further, the purification box 4 is provided with the pulling assembly 7 on one side, and the pulling assembly 7 is connected with the filter assembly 5. The filter assembly 5 is arranged in a sliding manner relative to the purification box 4, so that the filter assembly 5 can be quickly pulled out of the purification box 4 by the pulling assembly 7 for quick replacement.

[0039] Further, a plurality of filter assemblies 5 are vertically arranged in the purification box 4, and the adjacent filter assemblies 5 are provided with the slag separating layer 8. The filter assemblies 5 have different filtering effects, and are arranged from top to bottom as an initial filter assembly for filtering large particles, a medium filter assembly for filtering small particles and a high-efficiency filter assembly for filtering and adsorbing harmful gases. The filtering efficiency of each group of different filter assemblies 5 is inconsistent, so the replacement period is also different. When different filter assemblies 5 are replaced, the filtering space of different filter assemblies 5 needs to be isolated to prevent different particles from mixing together and leaving the filtering space.

[0040] Preferably, the slag separating layer 8 comprises a partition plate 801 fixed in the purification box 4 to intercept different types of filter assemblies 5. A plurality of ventilation grooves 802 are formed in the partition plate 801 to communicate with the adjacent two groups of filter assemblies 5. When the fan 3 works, the smoke can be sucked into the different filter assemblies 5 from the fume extraction pipe 2 for multiple filtering. A valve assembly is arranged in the ventilation groove 802, and the valve assembly is connected with a driving assembly arranged on the partition plate 801. The driving assembly can control the valve assembly to close or open the ventilation groove 802 when working. When the device works normally, the valve assembly opens the ventilation groove 802, and the filtering is carried out normally. When the filter assembly 5 is replaced, the valve assembly closes the ventilation groove 802, and the filtering materials in the different filtering spaces cannot mix.

[0041] Further, the slag collecting assembly 9 is arranged on the side of the purification box 4 away from the pulling assembly 7. When the filter assembly 5 is replaced, part of the filtering materials on the filter assembly 5 will fall onto the partition plate 801 of the slag separating layer 8 below. When the device continues to work after the subsequent replacement is completed, the filtering materials on the partition plate 801 will still fall into the lower filtering space when the valve assembly opens the ventilation groove 802. Therefore, the slag collecting assembly 9 is needed to collect and clean the filtering materials on the partition plate 801 during the replacement of the filter assembly 5.

[0042] Preferably, the slag collection assembly 9 includes a motor 902, the drive shaft of which is fixedly connected to one end of a scraper 903. The scraper 903 is slidably disposed on the upper surface of the partition 801. A hopper 904 is disposed below the motor 902, and the opening of the hopper 904 is located on one side of the upper surface of the partition 801. When the valve assembly closes the ventilation slot 802, the motor 902 starts, driving the scraper 903 to scrape off the filter material on the upper surface of the partition 801 and the surface of the valve assembly. Most of the filter material that falls off when replacing the filter assembly 5 is scraped into the hopper 904 on one side of the partition 801 for collection, thus preventing the filter material on the partition 801 from entering other filtration spaces through the ventilation slot 802 when the device is working normally after replacement.

[0043] Furthermore, a baffle pipe 6 is also installed at the smoke inlet of the purification box 4. Since the smoke drawn in by the smoke pipe 2 through the fan 3 is the smoke generated during industrial welding, the smoke drawn in may also contain workpiece welding particles separated during welding. These particles are hot, and even if the filter component 5 used to filter welding smoke in the prior art has a flame-retardant effect, the high-temperature welding particles may still damage the filter component 5.

[0044] Please refer to Figure 2 and Figure 5 In this embodiment, the baffle pipe 6 includes a ring plate 601, a baffle plate 602, and a top air pipe 603.

[0045] Specifically, the connection between the chassis 1 and the fume extraction pipe 2 is the fume extraction inlet. A baffle 602 is fixed inside the chassis 1, located below the fume extraction inlet and spaced apart from the fume extraction port. The top surface of the baffle 602 has a circular slot with the slot opening facing upwards. When welding particles enter the chassis 1 through the fume extraction pipe 2, they are blocked by the baffle 602 below the fume extraction inlet and fall into the circular slot. A ring plate 601 is fixedly installed on the outer wall of the fume extraction pipe 2 at the fume extraction inlet, positioned above the baffle 602, so that… Welding particles that fall into the circular slot are blocked by the ring plate 601 when they bounce off the slot surface and continue to bounce back into the circular slot, preventing them from splashing to other places and increasing safety. The entire fume inlet (i.e., the position of the baffle 602 and the ring plate 601) is fitted inside the top air pipe 603. The top end of the top air pipe 603 is fixedly connected to the top surface of the housing 1 and connects to the fume extraction pipe 2. The bottom end of the top air pipe 603 is fixedly connected to the purification box 4 and connects to the filter space inside the purification box 4, ensuring that the welding fumes completely flow into the filter space.

[0046] The diameter of the circular slot is larger than the outer ring diameter of the ring plate 601, and the outer ring diameter of the ring plate 601 is larger than the diameter of the fume inlet, thus ensuring the normal flow of fume gas while blocking welding block particles.

[0047] Please refer to Figures 2-4In this embodiment, the pull-out assembly 7 includes a slide groove 701, a sealing cavity 702, a sealing door 703, and a box door 704.

[0048] Specifically, the chute 701 is located inside the purification chamber 4 and extends through one side of the purification chamber 4. A sealing cavity 702 is fixedly installed on the outside of the through side of the purification chamber 4, forming a sealed space at the through point. The sealing cavity 702 is composed of a cavity plate. The cavity plate on one side of the sealing cavity 702 is set as a sealing door 703, which can be opened or closed manually. A sealing gasket is provided between the sealing door 703 and the sealing cavity 702. When the sealing door 703 is closed, the sealing cavity 702 can be sealed, preventing welding fumes inside the purification chamber 4 from leaking into the sealing cavity 702 through the chute 701 and then to the outside.

[0049] A filter assembly 5 is slidably installed inside the slide groove 701. One end of the filter assembly 5 is located in the sealed cavity 702 outside the purification box 4 through the slide groove 701, and a handle is fixed at this end for easy manual pulling. A box door 704 is provided on the side of the chassis 1 near the pull-out assembly 7. The box door 704 is opened manually to expose the purification box 4 inside the chassis 1. Then, the sealing door 703 of the sealed cavity 702 on the purification box 4 is opened, and the sealing assembly can be quickly pulled out for replacement.

[0050] Please refer to Figures 5-6 In this embodiment, the slag-separating layer 8 includes a partition plate 801, a ventilation slot 802, a valve assembly, and a drive assembly.

[0051] The valve assembly includes a sealing plate 803, a connecting block 804, and a connecting rod 805.

[0052] The drive assembly includes a slot plate 806 and a drive component 807.

[0053] Specifically, the partition 801 is located between adjacent filter components 5. The partition 801 is provided with several ventilation slots 802. One end of the sealing plate 803 is rotatably disposed in the ventilation slot 802. A connecting block 804 is fixed on the top surface of the other end of the sealing plate 803. All the connecting blocks 804 are rotatably connected to a connecting rod 805. One end of the rotating rod is fixedly connected to a drive component. When the drive component drives the rotating rod to move, all the sealing plates 803 swing through the rotating end, so that the sealing plates 803 rotate into the ventilation slots 802 and seal the opening of the ventilation slots 802.

[0054] When the sealing plate 803 closes the ventilation slot 802, the top surface of the sealing plate 803 and the upper plate surface of the partition plate 801 are on the same plane. This allows the scraper 903 on the slag collection assembly 9 to properly scrape the top surface of the sealing plate 803 and the upper plate surface of the partition plate 801, ensuring that the filter material is scraped clean.

[0055] In addition, the driving component 807 is fixed to the partition plate 801, and the driving end of the driving component 807 is fixedly connected to the slot plate 806. The slot plate 806 has a long slot on one end face near the rotating rod. One end of the rotating rod is slidably sleeved in the long slot, and the sliding direction is consistent with the through direction of the slot opening of the ventilation slot 802. When the driving component 807 drives the rotating rod to move, the sealing plate 803 swings. In order to counteract the displacement caused by the swing of the sealing plate 803, the rotating rod will slide in the long slot to ensure the normal swing of the sealing plate 803. The connection between the slot plate 806 and the rotating rod is engaged by a locking block to prevent the rotating rod from disengaging from the long slot of the slot plate 806.

[0056] Please refer to Figures 7-8 In this embodiment, the slag collection assembly 9 also includes a vertical groove 901.

[0057] Specifically, the vertical trough 901 is located in the side wall of the purification box 4 away from the pull-out assembly 7. The bottom of the vertical trough 901 is connected to the material hopper 904. The purification box 4 is equipped with an inclined partition 801. The inclined bottom end of the partition 801 is located on the side of the purification box 4 close to the vertical trough 901.

[0058] The vertical trough 901 and the upper plate of the partition 801 are respectively provided with material inlets. The number of material inlets of the partition 801 and the vertical trough 901 are one-to-one. The material inlets connect the vertical trough 901 to the inside of the purification box 4. The material inlets are regarded as the openings of the hopper 904, so that all the filter material scraped off the partition 801 can enter the hopper 904 through the vertical trough 901 for collection and storage, thus avoiding affecting the filtration space.

[0059] The partition 801 is equipped with a motor 902 and a scraper 903 at both ends. The motor 902 drives the scraper 903 to rotate 90 degrees from one end of the partition 801, bringing the scraper 903 closer to the end of the partition 801 near the feed inlet. The width of the scraper 903 is the same as the width of the feed inlet. Therefore, when the scraping is completed, the scrapers 903 at both ends of the partition 801 will rotate to the feed inlet, sealing the entire feed inlet with the scraper 903. This prevents the fan 3 from starting and drawing smoke into the filtration space. When this happens, an airflow velocity difference will be generated between the filtration space and the hopper 904, causing the filtered material in the hopper 904 to be drawn out from the feed inlet by the air pressure difference.

[0060] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
