Description

Technical Field

[0001] This invention relates to the field of welding fume purification equipment, specifically an adaptive smoke tracking system for welding fume purification equipment. Background Technology

[0002] Welding fumes refer to the large amount of smoke and dust generated during the welding process. They mainly originate from the particulate matter produced by the oxidation of metal materials at high temperatures during welding. These fumes may contain various toxic and harmful substances, such as heavy metals, benzene, toluene, and xylene. Long-term inhalation may have certain effects on human health, such as causing pneumoconiosis and lung cancer. Therefore, when performing welding operations, effective measures must be taken to reduce the hazards of welding fumes, such as using ventilation facilities and wearing protective masks.

[0003] Chinese invention patent CN103785264A, published on May 14, 2014, discloses a welding fume purifier, including a dust inlet box and a fan. The dust inlet box has a dust inlet, one side of which is connected to one end of a right-angle elbow. The other end of the right-angle elbow has an air intake. The other side of the dust inlet has a downward-sloping flame-arresting guide plate designed to extinguish sparking particles in the airflow. A filter is also installed inside the dust inlet box. This invention features a simple structure, small footprint, energy efficiency, stable operation, low noise, and easy operation. It effectively adsorbs fumes and exhaust gases generated during welding and other processing operations, providing good purification and high safety, effectively solving the problem of easily flammable sparking particles in welding fumes.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the position of the negative pressure air intake of the existing welding fume purifier cannot be moved automatically, and it cannot get close to the high-density dispersion point of the welding fume for adsorption. This results in the welding fume being dispersed over a large range in the air, which leads to a large volume of air that needs to be filtered for complete adsorption, resulting in low adsorption efficiency. It cannot be adapted to welding at any position in the welding area of ​​the factory, and cannot meet the adsorption requirements of multi-point welding. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide an adaptive smoke tracking system for welding fume purification equipment.

[0006] To achieve the above objectives, the present invention employs the following technical solutions;

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: The welding fume purification equipment adaptive tracking fume system of this invention includes a fixed top plate, a stepped plate, and symmetrical hanging plates; a stepped plate is rotatably inserted into a stepped groove on the fixed top plate; symmetrical hanging plates are symmetrically fixed to the lower surface of the stepped plate; a movable outer tube is rotatably inserted into the symmetrical hanging plates; a movable inner tube is slidably inserted into the lower end of the movable outer tube; a fixed ring is fixed to the lower end of the movable inner tube; multiple traction units are fixed to the fixed ring; multiple welding fume sensors are fixed to the fixed top plate corresponding to the movable inner tube; and a filter purification unit is connected and fixed to the side of the movable outer tube.

[0008] Furthermore, the traction unit includes a traction rope, a winding reel, and a first motor; the lower end of the traction rope is fixedly connected to a fixed ring; the upper end of the traction rope is fixedly connected to a winding reel; the first motor is fixedly connected to the winding reel; and the first motor is fixedly connected to the lower surface of the fixed top plate.

[0009] Furthermore, the filtration and purification unit includes a rigid tube and a purifier; the rigid tube is connected and fixed to the side of the movable outer tube; the purifier is fixed to the lower end of the rigid tube; a fixed seat is fixed to the rigid tube; the fixed seat is fixed to the lower surface of the turntable; the turntable is rotatably inserted into a plurality of limiting blocks; the limiting blocks are fixed to the lower surface of the fixed top plate.

[0010] Furthermore, a connecting shaft is inserted into the lower end of the movable inner tube; positioning sensors are symmetrically fixed to both ends of the connecting shaft; a movable upper plate is rotatably sleeved on the connecting shaft; a first groove is formed in the movable upper plate; a first shaft is slidably inserted into the first groove; sleeve plates are symmetrically sleeved on the first shaft; a second shaft is inserted into the lower end of the sleeve plates; the second shaft is slidably inserted into the second groove; the second groove is formed in the movable lower plate; a second tooth and a first tooth are respectively formed on the sides of the movable lower plate and the movable upper plate; a drive gear is meshed on the first tooth; a second motor is fixedly connected to the drive gear; the second motor is fixedly connected to the ground tube.

[0011] Furthermore, a first magnetic plate is fixedly connected to the side of the movable lower plate through a slot; a second magnetic plate is fixedly connected to the side of the movable upper plate; a limiting sleeve is sleeved on the movable upper plate; a third magnetic plate is fixedly connected to the limiting sleeve corresponding to the second magnetic plate; a fourth magnetic plate is fixedly connected to the ground pipe corresponding to the first magnetic plate; and a rolling unit is fixedly connected to both the ground pipe and the lower surface of the purifier.

[0012] Furthermore, the rolling unit includes a counterweight plate, a limiting plate, and balls; the limiting plate is fixedly connected to the lower surface of the counterweight plate; and multiple balls are rotatably connected between the counterweight plate and the limiting plate through a slot.

[0013] The adaptive smoke tracking system for welding fume purification equipment provided by this invention has the following beneficial effects:

[0014] 1. This invention uses a fixed top plate to fix the device to the inner ceiling of the workshop. Then, the traction unit and the filtration and purification unit are assembled. The filtration and purification unit is then turned on, allowing it to work with the welding fume sensor to detect the concentration of welding fumes in the workshop. The power of the filtration and purification unit is adjusted accordingly. Then, in conjunction with the traction unit, the lower air inlet of the movable inner tube can be moved to a position below the welding fume sensor that detects high concentrations of welding fumes for precise positioning and adsorption of high concentrations of welding fumes. This allows the welding fumes to be adsorbed and filtered before they diffuse, making it more accurate, energy-saving, and environmentally friendly. This solves the problems of low adsorption accuracy, low range, and low efficiency of existing welding fume adsorption equipment.

[0015] 2. This invention uses four first motors to pull traction ropes via a winding reel, allowing precise adjustment of the fixed ring at the lower end of the traction rope and the lower end of the movable inner tube. By controlling the different traction lengths of the four first motors, the lower end of the movable inner tube can move precisely up and down and left and right below the fixed top plate. Combined with a welding fume sensor, it can move and adsorb high-powered welding fumes from areas with high concentrations. The welding fumes sensor then determines whether adsorption is complete. Once adsorption is complete, the four first motors control the length of the traction ropes, keeping the movable inner tube rotating to adsorb air. This allows for adsorption over a large area in the welding workshop. The sliding insertion depth between the movable inner tube and the movable outer tube can be manually adjusted to increase the adsorption range at the lower end of the movable inner tube, resulting in greater adsorption efficiency. This solves the problems of small adsorption space and inability to displace the adsorption port in existing welding fume adsorption devices.

[0016] 3. The second motor, when energized, drives the active gear to engage the first and second teeth, raising the upper plate to a higher position. This allows the lower end of the movable inner tube to move significantly upwards or downwards, enabling it to hover at different heights for fume adsorption and at considerable distances. This adapts to welding equipment and operators at varying heights, allowing for close contact with the fume source and rapid adsorption without waiting for the fume to diffuse in the air. This reduces the power requirements for fume adsorption while ensuring concentrated collection and maintaining high-quality air quality. A positioning sensor precisely positions the lower end of the movable inner tube to accurately adsorb fume, achieving precise, low-power adsorption and saving energy. The positioning sensor, fume sensor, second motor, and first motor are connected via an Internet of Things (IoT) system. This system allows for real-time monitoring of the fume concentration and location in the welding area via the network. It enables the lower end of a cyclically moving inner tube to cruise around the perimeter. When no welding fumes are generated, it uniformly and slowly adsorbs and filters the air in the welding area over a large area. Then, when a high concentration of welding fumes is detected by the fume sensor above a certain location, the two first motors rotate simultaneously, releasing the traction rope and causing the fixed ring and moving inner tube to descend, bringing them close to the source of the welding fumes. The purifier then operates at maximum power for rapid adsorption. When the welding fumes sensor detects no fumes for one minute, the purifier stops adsorbing at maximum power, and the first motor pulls the traction rope, causing the fixed ring and moving inner tube to rise, entering cruise mode. This achieves energy-saving and precise fume adsorption, eliminating the need for continuous maximum power adsorption and filtration. It solves the problem that existing welding fume adsorption and filtration devices cannot actively track high-concentration fume locations or accurately pinpoint their location.

[0024] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0027] Please see Figure 1-4As shown, the welding fume purification equipment's adaptive tracking smoke system includes a fixed top plate 1, a stepped plate 2, and symmetrical hanging plates 3. The stepped plate 2 is rotatably inserted into a stepped groove on the fixed top plate 1. Symmetrical hanging plates 3 are symmetrically fixed to the lower surface of the stepped plate 2. A movable outer tube 4 is rotatably inserted into the symmetrical hanging plates 3. A movable inner tube 5 is slidably inserted into the lower end of the movable outer tube 4. A fixed ring 6 is fixed to the lower end of the movable inner tube 5. Multiple traction units are fixed to the fixed ring 6. Multiple welding fume sensors 14 are fixed to the fixed top plate 1 corresponding to the movable inner tube 5. A filter purification unit is connected and fixed to the side of the movable outer tube 4. During operation, the fixed top plate 1 is fixed to the inner ceiling of the workshop. Then, the traction unit and the filtration and purification unit are assembled. The filtration and purification unit is then turned on, which works with the welding fume sensor 14 to detect the concentration of welding fumes in the workshop. The power of the filtration and purification unit is adjusted accordingly. Then, in conjunction with the traction unit, the lower air inlet of the movable inner tube 5 can be moved to a position below the welding fume sensor 14 that detects high concentrations of welding fumes for precise positioning and adsorption of high concentrations of welding fumes. This allows the welding fumes to be adsorbed and filtered before they diffuse, making it more accurate, energy-saving, and environmentally friendly. This solves the problems of low adsorption accuracy, low range, and low efficiency of existing welding fume adsorption equipment.

[0028] The traction unit includes a traction rope 7, a take-up reel 8, and a first motor 9. The lower end of the traction rope 7 is fixed to a fixed ring 6. The upper end of the traction rope 7 is fixed to the take-up reel 8. The first motor 9 is fixed to the take-up reel 8. The first motor 9 is fixed to the lower surface of the fixed top plate 1. During operation, the four first motors 9 pull the traction rope 7 through the take-up reel 8, so that the positions of the fixed ring 6 fixed to the lower end of the traction rope 7 and the lower end of the movable inner tube 5 can be precisely adjusted. By controlling the different traction lengths of the four first motors 9, the lower end of the movable inner tube 5 can be precisely positioned below the fixed top plate 1. The device moves up and down and left and right, working in conjunction with the welding fume sensor 14 to move to areas with high welding fume concentration and then adsorb the fumes at high power. The welding fume sensor 14 then determines whether adsorption is complete. Once adsorption is complete, the four first motors 9 control the length of the traction ropes 7, keeping the movable inner tube 5 rotating to adsorb air. This allows for adsorption over a large area in the welding workshop. The sliding insertion depth between the movable inner tube 5 and the movable outer tube 4 can be manually adjusted to increase the adsorption range at the lower end of the movable inner tube 5, resulting in greater adsorption efficiency. This solves the problem of small adsorption space and inability to displace the adsorption port in existing welding fume adsorption devices.

[0029] The filtration and purification unit includes a rigid tube 10 and a purifier 15. The rigid tube 10 is connected and fixed to the side of the movable outer tube 4. The purifier 15 is fixed to the lower end of the rigid tube 10. A fixed seat 11 is fixed to the rigid tube 10. The fixed seat 11 is fixed to the lower surface of the turntable 12. The turntable 12 is rotatably inserted into multiple limiting blocks 13. The limiting blocks 13 are fixed to the lower surface of the fixed top plate 1. During operation, the high-power purifier 15 adsorbs and filters the air in the rigid tube 10, the movable outer tube 4, and the movable inner tube 5. The modular filter components in the purifier 15 make it easy to replace the filter plates and obtain continuous filtration function.

[0030] A connecting shaft 19 is inserted into the lower end of the movable inner tube 5; positioning sensors 20 are symmetrically fixed to both ends of the connecting shaft 19; a movable upper plate 21 is rotatably sleeved on the connecting shaft 19; a first groove 22 is opened in the movable upper plate 21; a first shaft 24 is slidably inserted into the first groove 22; a sleeve plate 25 is symmetrically sleeved on the first shaft 24; a second shaft 26 is inserted into the lower end of the sleeve plate 25; the second shaft 26 is slidably inserted into the second groove 28; the second groove 28 is opened in the movable lower plate 27; a second tooth 29 and a first tooth 23 are respectively opened on the sides of the movable lower plate 27 and the movable upper plate 21; a drive gear 30 is meshed on the first tooth 23; a second tooth 29 is fixed on the drive gear 30. The second motor 31 is fixedly connected to the ground pipe 36. During operation, the second motor 31, when energized, drives the drive gear 30 to mesh with the first tooth 23 and the second tooth 29, thereby raising the movable upper plate 21 to a higher position. This allows the lower end of the movable inner pipe 5 to move upwards or downwards a significant distance, enabling the lower end of the movable inner pipe 5 to hover at different heights for fume adsorption and at large distances for fume adsorption. In other words, it is adaptable to welding equipment and operators at different heights, allowing for close contact with the source of welding fumes and rapid adsorption without waiting for the fumes to diffuse in the air, thus reducing the power requirements for adsorption. This system ensures concentrated collection of welding fumes, maintaining consistently high air quality. The positioning sensor 20 allows for precise positioning of the lower end of the movable inner tube 5, adjusting it to fit the welding fume source for accurate, low-power adsorption, thus saving energy and enhancing intelligence. The IoT connection between the positioning sensor 20, welding fume sensor 14, second motor 31, and first motor 9 enables real-time monitoring of the fume concentration and location in the welding area. This allows for the cyclical movement of the lower end of the movable inner tube 5, enabling circular cruising. When no welding fumes are generated, it uniformly and rapidly adsorbs and filters the air in the welding area over a large area. Then, when welding fumes are present above a certain location... When sensor 14 detects high concentration data, the two first motors 9 rotate simultaneously, releasing the traction rope 7. This causes the fixed ring 6 and the movable inner tube 5 to descend, bringing them close to the welding fume source. The purifier 15 then operates at maximum power for rapid adsorption. When the welding fume sensor 14 detects no welding fume for one minute, the purifier 15 stops operating at maximum power for rapid adsorption. The first motor 9 pulls the traction rope 7, causing the fixed ring 6 and the movable inner tube 5 to rise, entering cruise mode. This achieves the function of accurately adsorbing welding fumes while saving power, eliminating the need for continuous maximum power adsorption and filtration. This solves the problem that existing welding fume adsorption and filtration devices cannot actively track the location of high fume concentrations and cannot accurately locate the position of high-concentration welding fumes.

[0031] A first magnetic plate 32 is fixedly connected to the side of the movable lower plate 27 through a slot; a second magnetic plate 33 is fixedly connected to the side of the movable upper plate 21; a limiting sleeve 35 is sleeved on the movable upper plate 21; a third magnetic plate 34 is fixedly connected to the limiting sleeve 35 corresponding to the second magnetic plate 33; a fourth magnetic plate 37 is fixedly connected to the ground pipe 36 corresponding to the first magnetic plate 32; a rolling unit is fixedly connected to both the ground pipe 36 and the lower surface of the purifier 15; during operation, the magnetic connection between the first magnetic plate 32 and the fourth magnetic plate 37 enables... After the lower movable plate 27 descends and fully enters the receiving tube 36, it moves to the left, pulling the sleeve 25 to rotate and align with the fourth magnetic plate 37. This allows the upper movable plate 21 to continue its vertical descent, while the limiting sleeve 35 remains stationary due to the receiving tube 36. When the upper movable plate 21 rises, the limiting sleeve 35 descends, and the third magnetic plate 34 is magnetically connected to the second magnetic plate 33, fixing the limiting sleeve 35 around the upper movable plate 21, the lower movable plate 27, and the sleeve. The upper movable plate 21 and the lower movable plate 27 are kept vertical, thus vertically supporting the lower end of the movable inner tube 5. By maintaining the vertical position of the connecting shaft 19 connected to the upper end of the upper movable plate 21 and the lower end of the movable inner tube 5, a large distance can be moved up or down. This allows the lower end of the movable inner tube 5 to be suspended at different heights for adsorption and at a large distance for adsorption of welding fumes. In other words, it can be adapted to welding equipment and operators of different heights, allowing it to be in close proximity to the source of welding fumes. This allows for rapid adsorption without waiting for the welding fumes to diffuse in the air, reducing the power requirements for adsorption and ensuring concentrated collection of welding fumes, thus maintaining high air quality. The rolling unit is fixed to the lower surface of the ground pipe 36 and the purifier 15, so that the ground pipe 36 and the purifier 15 have low resistance when being pulled, thus facilitating rapid movement to the source of welding fumes for adsorption. This solves the problem that existing welding fume collection and tracking systems cannot adjust the height position for adsorption.

[0032] The rolling unit includes a counterweight plate 16, a limiting plate 17, and ball bearings 18. The limiting plate 17 is fixedly connected to the lower surface of the counterweight plate 16. A plurality of ball bearings 18 are rotatably connected between the counterweight plate 16 and the limiting plate 17 through a slot. During operation, the lower half of the ball bearings 18 contacts the ground and rolls, thereby enabling the horizontal movement of the ground pipe 36 and the purifier 15 to achieve low resistance, making the movement more convenient.

[0033] Using the above scheme, in use, the invention is fixed to the inner ceiling of the workshop by a fixed top plate 1, then the traction unit and the filtration and purification unit are assembled. The filtration and purification unit is then activated, allowing the welding fume sensor 14 to detect the concentration of welding fumes in the workshop. The filtration and purification unit adjusts its power accordingly. The traction unit, in conjunction with the lower air inlet of the movable inner tube 5, moves to a position below the welding fume sensor 14 that detects high-concentration welding fumes, precisely positioning and adsorbing the high-concentration welding fumes. This ensures that the welding fumes are adsorbed and filtered before they diffuse, making it more accurate, energy-efficient, and environmentally friendly. This solves the problems of low adsorption accuracy, low range, and low efficiency in existing welding fume adsorption equipment. The four first motors 9 are used to... The reel 8 pulls the traction rope 7, allowing precise adjustment of the fixed ring 6 at the lower end of the traction rope 7 and the lower end of the movable inner tube 5. By controlling the different traction lengths of the four first motors 9, the lower end of the movable inner tube 5 can move precisely up and down and left and right below the fixed top plate 1. Combined with the welding fume sensor 14, it can move and powerfully adsorb areas with high welding fume concentrations. The welding fume sensor 14 then determines whether adsorption is complete. After adsorption is complete, the four first motors 9 control the length of the traction rope 7, keeping the movable inner tube 5 rotating to adsorb air. This allows for adsorption over a large area within the welding workshop. The movable inner tube 5 and the movable inner tube 5 can be manually adjusted. The sliding insertion depth between the outer tubes 4 is increased, thereby artificially expanding the adsorption range at the lower end of the movable inner tube 5, resulting in greater adsorption efficiency and solving the problem of small adsorption space and inability to displace the adsorption port in existing welding fume adsorption devices. Adsorption is performed by a high-power purifier 15, which adsorbs and filters the air inside the rigid tube 10, movable outer tube 4, and movable inner tube 5. The modular filter components within the purifier 15 facilitate easy replacement of the filter plates, providing continuous filtration. The second motor 31, when energized, drives the drive gear 30 to mesh with the first tooth 23 and the second tooth 29, allowing the movable upper plate 21 to rise to a higher position, thus increasing the height of the lower end of the movable inner tube 5. The movable inner tube 5 can move a large distance upwards or downwards, allowing its lower end to hover at different heights for fume adsorption and at a considerable distance for fume adsorption. This means it can be adapted to welding equipment and operators at different heights, enabling close contact with the source of welding fumes and rapid adsorption without waiting for the fumes to diffuse in the air. This reduces the power requirements for adsorption while ensuring concentrated collection of welding fumes and maintaining high-quality air quality. The positioning sensor 20 allows for precise positioning of the lower end of the movable inner tube 5, adjusting it to a suitable position to contact the source of welding fumes, achieving precise, low-power adsorption, thus saving energy and making it more intelligent.Through the Internet of Things (IoT) connection of positioning sensor 20, welding fume sensor 14, second motor 31, and first motor 9, the concentration and location of fumes in the welding area can be detected in real time via the network. This allows for the setting of a cyclically moving inner tube 5, which cruises in a circular motion. When no welding fumes are generated, it uniformly and slowly adsorbs and filters the air in the welding area over a large area. Then, when the welding fume sensor 14 detects a high concentration at a certain location, the two first motors 9 rotate simultaneously, releasing the traction rope 7. This causes the fixed ring 6 and the moving inner tube 5 to descend, bringing them close to the source of the welding fumes, and enabling the purifier 15 to rapidly adsorb fumes at maximum power. When the welding fume sensor 14 detects no welding fumes for one minute, the purifier stops working. Purifier 15 stops its maximum power for rapid adsorption. The first motor 9 pulls the traction rope 7, causing the fixed ring 6 and the movable inner tube 5 to rise, entering cruise mode. This achieves the function of accurately adsorbing welding fumes while saving power, eliminating the need for continuous maximum power adsorption and filtration. This solves the problem that existing welding fume adsorption and filtration devices cannot actively track the location of high-concentration fumes and cannot accurately locate the position of high-concentration welding fumes. Through the magnetic connection between the first magnetic plate 32 and the fourth magnetic plate 37, after the movable lower plate 27 descends and fully enters the receiving tube 36, it moves to the left, pulling the sleeve plate 25 to rotate, so that it fits against the fourth magnetic plate 37. Then, it avoids the descending space of the movable upper plate 21, allowing the movable upper plate 21 to continue to descend vertically, and then stops. The sleeve 35 remains stationary due to being blocked by the connecting pipe 36. When the movable upper plate 21 rises, the limiting sleeve 35 descends. The third magnetic plate 34 and the second magnetic plate 33 are magnetically connected and fixed, causing the limiting sleeve 35 to fit onto the movable upper plate 21, the movable lower plate 27, and the sleeve plate 25. This keeps the movable upper plate 21 and the movable lower plate 27 vertical, thus vertically supporting the lower end of the movable inner tube 5. By maintaining the verticality of the connecting shaft 19 connected to the upper end of the movable upper plate 21 and the height position of the lower end of the movable inner tube 5, a large distance can be moved upward or downward. This allows the lower end of the movable inner tube 5 to be suspended at different heights for adsorption and to be suspended at a large distance for adsorption of welding fumes. In other words, it can be adapted to welding equipment and operations at different heights. The system allows for close proximity to the source of welding fumes, enabling rapid adsorption without waiting for the fumes to diffuse in the air. This reduces the power requirements for adsorption while ensuring concentrated collection of welding fumes and maintaining consistently high air quality. The rolling unit, fixed to the lower surfaces of the contact pipe 36 and the purifier 15, minimizes resistance during movement, facilitating rapid and convenient transport to the welding fume source. This solves the problem of existing welding fume collection and tracking systems being unable to adjust their height for adsorption. The lower half of the ball bearing 18 rolls in contact with the ground, achieving low-resistance horizontal movement of the contact pipe 36 and the purifier 15, further enhancing ease of movement.
