Description

Technical Field

[0001] The invention relates to the technical field of electric welding fume collection, and in particular to an environmentally friendly electric welding fume collection and processing device. Background Art

[0002] Welding fume is a mixed aerosol formed by the oxidation of metal with air after evaporation under the action of high arc temperature (3000-6000℃). It contains metal oxide particles and harmful gases. Its main components are iron oxide, silicon dioxide and manganese oxide. Long-term inhalation can cause pneumoconiosis, chronic bronchitis, etc. Silicon dioxide can cause silicosis, and because it contains manganese, hydrogen fluoride and other substances, it increases the risk of lung cancer and nasopharyngeal cancer. Therefore, during electric welding operations, it is usually necessary to collect and treat the welding fume;

[0003] There are many ways to collect and treat welding smoke, such as local proximity collection, top suction collection, room-type / enclosed collection, blowing and suction collection, mobile purification equipment, etc. Mobile purification equipment also includes welding smoke purifiers. This type of equipment is a device body plus a pipeline. The pipeline is covered in the welding work area, and then it is sucked into the main body of the equipment through the pipeline for purification. The welding smoke is first of all high in temperature. The smoke is directly sucked into the equipment and easily damages the equipment, shortening its service life.

DETAILED DESCRIPTION

[0027] Embodiment 1, by Figure 1-8 The present invention includes a welding fume purifier 1, wherein an exhaust mechanism 2, two water tanks 3 distributed up and down, an air intake mechanism 5 and a water adding mechanism 6 are installed on the front side of the welding fume purifier 1, wherein the water tank 3 is located between the exhaust mechanism 2 and the air intake mechanism 5, and the water adding mechanism 6 is located on the rear side of the air intake mechanism 5, and a slag discharge mechanism 4 is installed inside the water tank 3.

[0028] The exhaust mechanism 2 includes a connecting air box 21, which is fixedly connected to the front side of the welding fume purifier 1 by bolts. An exhaust pipe 22 is fixedly connected to the top of the connecting air box 21. The end of the exhaust pipe 22 is fixedly connected to the air inlet of the welding fume purifier 1. One side of the connecting air box 21 is fixedly connected to two connecting pipes 23 distributed up and down. The end of the connecting pipe 23 is fixedly connected to the top of the water tank 3, and the connecting pipe 23 is respectively connected to the inside of the connecting air box 21 and the inside of the water tank 3.

[0029] The air intake mechanism 5 includes an air intake main pipe 51, which is located on a side of the water tank 3 away from the exhaust mechanism 2. The top of the air intake main pipe 51 is fixedly connected to a bellows 52 through a flange, and the end of the bellows 52 is fixedly connected to a collecting cover 53. The outer end of the air intake main pipe 51 is fixedly connected to two air intake branch pipes 54, which pass through the top of the water tank 3 and extend to the inside of the water tank 3. A plurality of air intake holes 56 are opened on the outer side wall of the air intake branch pipe 54, and the air intake holes 56 are located inside the water tank 3. A solenoid valve 55 is installed on the air intake branch pipe 54, and the solenoid valve 55 is located above the water tank 3. The outer end of the air intake main pipe 51 is sleeved with two A fixing seat 57 is provided, and the air intake main pipe 51 is fixedly connected to the front side of the welding smoke purifier 1 through the fixing seat 57. The collecting hood 53 can be used universally through the bellows 52, and the collecting hood 53 covers the working area during the electric welding operation, so as to directly suck away the electric welding smoke. The air inlet 56 on the air inlet branch pipe 54 is located on the lower surface of the air inlet branch pipe 54. Therefore, the air discharged from the air inlet 56 and the particulate impurities adsorbed by water inside can only settle down to the bottom of the water tank 3, and will not pass through the air inlet 56 again to enter the air inlet branch pipe 54. Here, it means that the solenoid valve 55 on the corresponding air inlet branch pipe 54 is closed, and the air inlet branch pipe 54 is temporarily not ventilated.

[0030] The exhaust mechanism 2 and the air intake mechanism 5 cooperate to form a passage between the exhaust mechanism 2, the air intake mechanism 5 and one of the water tanks 3 by opening a certain solenoid valve 55. The two water tanks 3 can be used alternately to cool the water in the water tank 3 and to discharge and clean the particulate impurities in the water in the water tank 3. The equipment does not need to be stopped throughout the process, and the welding smoke can be collected and processed continuously.

[0031] Embodiment 2, on the basis of embodiment 1, the bottom of the water tank 3 is provided with an opening 31, the middle of the opening 31 is fixedly connected with a ridge-shaped plate 32, the ridge-shaped plate 32 divides the inside of the opening 31 into two gaps, the slag discharge mechanism 4 includes a collecting box 46, the collecting box 46 is fixedly connected to the bottom of the water tank 3, and the opening 31 is located above the collecting box 46, the front side of the bottom of the collecting box 46 is fixedly connected with a drain pipe 47, the drain pipe 47 is installed with a valve, the ridge of the ridge-shaped plate 32 is fixedly connected to the bottom of the water tank 3, and the drain pipe 47 is installed with a valve, and the ridge of the ridge-shaped plate 32 is fixedly connected to the bottom of the water tank 3. The top is at the same height as the bottom wall of the water tank 3, so the ridge-shaped plate 32 will not interfere with the scraper 45 when the scraper 45 moves to above the opening 31. In addition, due to the shape characteristics of the ridge-shaped plate 32, the particulate impurities that are scraped to the opening 31 by the scraper 45 but do not directly enter the gap, that is, the particulate impurities that fall on the ridge-shaped plate 32, can slide down along the ridge-shaped slope of the ridge-shaped plate 32, and will eventually fall into the gap and enter the collection box 46. The collection box 46 is used to uniformly collect the particulate impurities in the water tank 3.

[0032] The slag discharge mechanism 4 also includes an electric push rod 41, which is fixedly connected to the top center of the water tank 3. The end of the piston rod of the electric push rod 41 is fixedly connected to a blocking frame 42, which is located inside the water tank 3 and extends to the inside of the ridge-shaped plate 32. The blocking frame 42 includes a connecting plate 421, which is fixedly connected to the end of the piston rod of the electric push rod 41. The bottom of the connecting plate 421 is fixedly connected to two connecting rods 422, and the bottom of the connecting rod 422 is fixedly connected to the blocking plate 4 23. The blocking plate 423 is adapted to be located inside the gap, and a sealing ring 424 is embedded in the outer end of the blocking plate 423. When the blocking plate 423 is adapted to block inside the gap, the sealing ring 424 is tightly attached to the inner wall of the gap, thereby improving the sealing performance of the blocking plate 423 on the gap, ensuring that when the sewage carrying particulate impurities in the collection box 46 is discharged, the water in the water tank 3 will not enter the collection box 46 and be discharged together, and when the electric push rod 41 drives the blocking frame 42 to move up and down, it will not interfere with the rotating rod 44.

[0033] The slag discharge mechanism 4 also includes a motor 43, which is fixedly connected to the bottom of the water tank 3 away from the exhaust mechanism 2. The output shaft of the motor 43 is fixedly connected to a rotating rod 44, which is located inside the water tank 3, and the end of the motor 43 is movably connected to the inner wall of the water tank 3. The rotating rod 44 runs through two connecting rods 422. The outer end of the rotating rod 44 is processed with two threads in opposite directions, and the outer end of the rotating rod 44 is threadedly connected to two scrapers 45 distributed on the left and right. The two scrapers 45 are respectively located on both sides of the opening 31, and the bottom and side of the scraper 45 are respectively in contact with the bottom end and the inner wall of the water tank 3. The threads on the rotating rod 44 are in opposite directions, and the two scrapers 45 are on the rotating rod 4 4 is symmetrically distributed, so when the motor 43 drives the rotating rod 44 to rotate, the two scrapers 45 move closer to or away from each other along the rotating rod 44 inside the water tank 3. When there is no operation, the two scrapers 45 are sufficiently far away from each other. At this time, the particulate impurities precipitated in the water tank 3 are all located between the two scrapers 45. When slag discharge and cleaning are required, the two scrapers 45 approach each other again and scrape the particulate impurities precipitated in the water tank 3 to the opening 31. At this time, it is necessary to first drive the blocking frame 42 to move up by the electric push rod 41, so as to avoid interference between the blocking plate 423 in the blocking frame 42 and the scraper 45, and also to avoid the gap being blocked by the blocking plate 423 and unable to guide the particulate impurities scraped by the scraper 45 into the collection box 46.

[0034] When the corresponding water tank 3 is suspended and needs to be cooled and discharged, the interior of the water tank 3 is connected with the interior of the collecting box 46 through the opening 31. At this time, the scraper 45 can scrape the particulate impurities precipitated in the water tank 3 to the opening 31 and introduce them into the collecting box 46 through the gap. When the particulate impurities collected in the collecting box 46 need to be discharged, the electric push rod 41 is used to push the blocking frame 42 downward and block it in the gap through the blocking plate 423. At this time, the interior of the water tank 3 is no longer connected with the collecting box 46. Therefore, when the valve on the drain pipe 47 is opened to discharge the sewage carrying particulate impurities in the collecting box 46 through the drain pipe 47, the water in the water tank 3 will not be discharged together.

[0035] The water adding mechanism 6 includes a water inlet main pipe 61, which is located at one side of the welding smoke purifier 1. The front side of the water inlet main pipe 61 is fixedly connected to two water inlet branch pipes 62 distributed up and down through a tee. The ends of the water inlet branch pipes 62 pass through the top of the water tank 3 and extend to the inside of the water tank 3. A solenoid valve 2 63 is installed on the water inlet branch pipe 62. Two fixing seats 2 64 are provided at the outer end of the water inlet branch pipe 62. The water inlet branch pipe 62 is fixedly connected to the front side of the welding smoke purifier 1 through the fixing seats 2 64. A water level sensor 7 is fixedly connected to one side of the inside of the welding smoke purifier 1.

[0036] When the water tank 3 is suspended for sedimentation and slag discharge, the water in the water tank 3 is in a natural cooling state. At the same time, as part of the water in the water tank 3 is discharged, the water level in the water tank 3 is detected by the water level sensor 7, and the water level height range is set in advance. When the water level is insufficient, water is added to the designated water tank 3 through the water adding mechanism 6, and the water adding is automatically stopped after the water level reaches the requirement. The act of adding water also further reduces the water temperature in the raw water tank 3 and accelerates its cooling speed.

[0037] The electric push rod 41, motor 43, solenoid valve 1 55, solenoid valve 2 63 and water level sensor 7 mentioned above are all controlled by a controller or a computer terminal, and such control means and power supply and control methods are all existing conventional technologies, so they will not be described in detail here.

[0038] Working principle:

[0039] Start the welding fume purifier 1, and use the suction mechanism 2 to pump the two water tanks 3 to a negative pressure state, and then use the air intake mechanism 5 to negatively suck the welding fume into the water tank 3. Each time the welding fume is collected, only the solenoid valve 55 on one of the air inlet branches 54 is opened. After the welding fume is sucked into one of the water tanks 3 by the air intake mechanism 5, the dust particles in the fume float up in the water in the water tank 3 along with the air. During this period, part of the dust in the air will be absorbed and retained in the water. At the same time, the water in the water tank 3 will also cool the air containing the welding fume. The air that floats to the surface will then be sucked into the welding fume purifier 1 through the suction mechanism 2, and the welding fume will be fully collected and processed.

[0040] After a period of time, the water in one of the water tanks needs to be cooled and the particulate matter collected in the water also needs to be discharged and collected. At this time, the original solenoid valve 55 can be closed and the solenoid valve 55 on the other air inlet branch pipe 54 can be opened, so that the welding smoke sucked by the air intake mechanism 5 enters the other water tank 3 and continues to be processed according to the above process. For the water tank 3 that is not used temporarily, let it stand for a certain period of time to allow the particulate matter in the water inside to fully settle, and then start its corresponding electric push rod 41, which drives the blocking frame 42 to move up until the blocking plate 423 in the blocking frame 42 no longer blocks the gap in the opening 31, and then start the motor 43. After the motor 43 is started The rotating rod 44 is driven to rotate, so that the two scrapers 45 move closer to each other. The scrapers 45 can push the particles settled at the bottom of the water tank 3 to the opening 31, and finally enter the collection box 46 through the gap, and the particles falling on the ridge-shaped plate 32 will also slide down along the slope of the top of the ridge-shaped plate 32. After the above operation is completed, the above steps are reversed, that is, the two scrapers 45 are separated and moved away again, and the blocking frame 42 moves down to block the gap through the blocking plate 423. At this time, the inside of the collection box 46 is isolated from the inside of the water tank 3. The valve on the sewage pipe 47 can be opened to discharge the sewage containing particles in the collection box 46 through the sewage pipe 47. The two water tanks 3 are used alternately according to the above steps.

[0041] As the water in the water tank 3 is discharged again and again, when the water level sensor 7 detects that the water level in the water tank 3 is lower than the set minimum height, the solenoid valve 2 63 on the water inlet branch 62 corresponding to the water tank 3 in the water adding mechanism 6 is started, so that clean water can be added to the water tank 3. When the water level sensor 7 detects that the water level in the water tank 3 is higher than the set maximum position, the solenoid valve 2 63 is closed and no water is added. This process not only ensures that the water level height inside the water tank 3 does not affect the use, but also plays a role in lowering the water temperature inside the original water tank 3 after water is added.
