Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a small combined high-efficiency welding fume absorption and purification device. Background Technique

[0002] When workers carry out welding processing on workpieces, welding fumes are usually easily generated. The welding fumes contain dirt such as metal dust, harmful gases and carcinogenic substances. After the workers come into contact with the welding fumes, the dirt such as metal dust, harmful gases and carcinogenic substances is likely to affect the physical health of the workers. Therefore, when welding, workers usually adopt an absorption device for welding fumes. The absorption device for welding fumes is a device used to remove dirt such as metal dust, harmful gases and carcinogenic substances generated during the welding process. Its main function is to protect the health of workers and meet the requirements of environmental protection at the same time.

[0003] A small combined high-efficiency welding fume absorption and purification device in the prior art includes an adsorption pipe and an adsorption box. One end of the adsorption pipe faces the workpiece, and the other end of the adsorption pipe is communicated with the adsorption box. The adsorption box is used to transmit the fumes into the adsorption box and process the fumes in the adsorption box, so as to purify the fumes.

[0004] Deficiencies of the prior art:

[0005] When workers weld workpieces, they need to hold the end of the adsorption pipe by hand and orient the nozzle at the end of the adsorption pipe away from the adsorption box towards the workpiece. Then, the workers transmit the fumes generated by the workpiece into the adsorption box, and the adsorption box processes dirt such as metal dust in the fumes. During this process, since the workers hold the end of the adsorption pipe by hand, it is inconvenient for the workers to process the workpiece, time-consuming and laborious, seriously affecting the work efficiency of the workers.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] 1. In this small combined high-efficiency welding fume absorption and purification device, when workers process workpieces, the magnetic parts on the adsorption pipe are magnetically connected to the workpieces, making the nozzle of the adsorption pipe face the workpieces. When the negative pressure source operates, the fumes generated by the workpieces are transmitted to the adsorption box after passing through the adsorption pipe. Thus, it is not necessary for workers to hold the nozzle of the adsorption pipe, saving the workload of the workers. At the same time, after the fumes pass through the adsorption pipe and reach the cleaning bucket in the adsorption box, dirt such as metal dust in the fumes remains in the cleaning holes on the cleaning bucket, and then through the cleaning liquid in the cleaning box, the dirt such as metal dust in the fumes is further cleaned, reducing the dirt such as metal dust in the fumes and making the fumes reach the emission standard before being discharged.

[0024] 2. In this small combined high-efficiency welding fume absorption and purification device, by setting a signal source, a receiver, a counter and a controller, when the negative pressure source operates, it drives the fan blades to rotate synchronously. The rotation of the fan blades blocks the signal transmitted from the signal source to the receiver. Through the counter, the number of times the fan blades are blocked within the set time is compared with the set value. When the cleaning holes on the side wall of the cleaning bucket are blocked by dirt, the flow rate of the fumes in the adsorption box decreases after passing through the adsorption pipe. As a result, when the fumes contact the fan blades, the rotation speed of the fan blades decreases, causing the number of times the fan blades are blocked to be lower than the set value on the counter. At this time, the controller issues a control signal to control the lighting of the signal lamp to remind the workers to clean the cleaning bucket.

[0025] 3. In this small combined high-efficiency welding fume absorption and purification device, when the filter plate moves up and down, the brush on the support plate contacts the side wall of the filter plate to brush off the dirt on the filter plate. After the dirt on the filter plate is separated from the filter plate, it is transmitted to the collection box through the transfer plate, further reducing the dirt in the fumes and making the fumes meet the emission standard before being discharged.

[0038] Please refer to Figure 1-7 As shown, a technical solution of a small combined high-efficiency welding fume absorption and purification device provided by the present utility model is as follows:

[0039] A small combined high-efficiency welding fume absorption and purification device includes an adsorption box 1 and adsorption pipes 13. The workpiece 15 is made of a magnetic material. Specifically, materials such as iron are selected for the workpiece 15. The vertically arranged adsorption box 1 is located on one side of the workpiece 15. An air outlet hole 11 is opened at the top of the adsorption box 1, and the air outlet hole 11 penetrates through the top of the adsorption box 1 in the vertical direction. A roller 12 is installed at the bottom of the adsorption box 1, and the roller 12 is rotatably connected to the bottom of the adsorption box 1. There are two adsorption pipes 13, and the two adsorption pipes 13 are distributed on both sides of the adsorption box 1. Each adsorption pipe 13 is selected as a telescopic hose. One end of each adsorption pipe 13 is communicated with the adsorption box 1, and a magnetic member 14 is installed at the other end of each adsorption pipe 13. The magnetic member 14 is selected as a magnet, and the magnetic member 14 is magnetically connected to the workpiece 15.

[0040] A collection box 23, a transmission plate 24, a cleaning barrel 3, a cleaning mechanism 4, and a negative pressure source 6 are installed in the adsorption box 1. The horizontally arranged collection box 23 is located at the bottom wall of the adsorption box 1, and the collection box 23 is open. The side wall of the collection box 23 is detachably connected to the inner side wall of the adsorption box 1 by bolts. There are multiple transmission plates 24, and the multiple transmission plates 24 are all located on the top of the collection box 23. The multiple transmission plates 24 are evenly distributed along the length direction of the adsorption box 1. A gap for the transmission of dirt in the flue gas is provided between each transmission plate 24, and the side wall of each transmission plate 24 is fixedly connected to the inner side wall of the adsorption box 1. The vertically arranged cleaning barrel 3 is located on the top of the transmission plate 24, and the bottom of the cleaning barrel 3 is detachably connected to the top of the transmission plate 24 by bolts. A cleaning hole 31 through which the flue gas can pass is opened on the side wall of the cleaning barrel 3.

[0041] The cleaning mechanism 4 includes a one-way valve 41 and a cleaning box 42. The one-way valve 41 is located on the top of the cleaning box 42. One end of the one-way valve 41 is communicated with the top of the cleaning barrel 3, and the other end of the one-way valve 41 is communicated with the bottom of the cleaning box 42. The horizontally arranged cleaning box 42 is located in the adsorption box 1, and a cleaning liquid is provided in the cleaning box 42.

[0042] There are three negative pressure sources 6, and the three negative pressure sources 6 are evenly distributed along the circumferential direction of the cleaning barrel 3. Each negative pressure source 6 is located at the top of the cleaning box 42. Each negative pressure source 6 includes a vacuum pump 61 and a transmission pipe 62. Each vacuum pump 61 is fixedly connected to the top wall of the adsorption box 1. Each vacuum pump 61 is communicated with the transmission pipe 62, and the transmission pipe 62 is communicated with the cleaning box 42.

[0043] When the staff processes the workpiece 15, through the magnetic connection between the magnetic part 14 and the workpiece 15, the staff aims the nozzle of the adsorption pipe 13 at the workpiece 15, and there is no need for the staff to hold the adsorption pipe 13 by hand, saving the workload of the staff. At the same time, the staff starts the vacuum pump 61. The flue gas generated during the processing of the workpiece 15 is transmitted into the adsorption box 1 after passing through the adsorption pipe 13. Through the cleaning effect of the cleaning hole 31 on the cleaning barrel 3, part of the dirt remains on the outer side wall of the cleaning hole 31. The flue gas is then transmitted into the cleaning box 42 after passing through the one-way valve 41. The dirt in the flue gas comes into full contact with the cleaning liquid in the cleaning box, so that the dirt in the flue gas remains in the cleaning liquid, further reducing the dirt in the flue gas. After multiple cleanings, when the flue gas meets the emission requirements, it is then discharged through the air outlet hole 11.

[0044] A connection box 21 and a connecting pipe 22 are installed in the adsorption box 1. There are two connection boxes 21 and two connecting pipes 22, and the two connection boxes 21 and the two connecting pipes 22 correspond to the two adsorption pipes 13 one by one. The side wall of each connection box 21 is fixedly connected to the side wall of the adsorption box 1, and one side of the connection box 21 is communicated with the adsorption pipe 13, and the other side of the connection box 21 is communicated with the connecting pipe 22. A cleaning liquid is installed in the connection box 21. The nozzle of the end of the connecting pipe 22 far from the connection box 21 faces the side wall of the cleaning barrel 3. When the flue gas is transmitted from the adsorption pipe 13 into the adsorption box 1, it is cleaned by the cleaning liquid in the connection box 21, so as to initially clean the flue gas. After the dirt in the flue gas comes into contact with the cleaning liquid in the connection box 21, part of the dirt remains in the connection box 21, and the flue gas is then transmitted into the cleaning barrel 3 after passing through the connecting pipe 22.

[0045] To further reduce the contaminants in the flue gas, a guide plate 51 and a spray head 52 are installed in the cleaning box 42. There are two guide plates 51 and two spray heads 52. The two guide plates 51 and the two spray heads 52 are distributed on both sides of the cleaning box 42, and each guide plate 51 corresponds to each spray head 52 one by one. The side wall of each inclined guide plate 51 is fixedly connected to the inner side wall of the cleaning box 42. A gap through which the flue gas can pass is provided between the two guide plates 51. The spray head 52 is located at the bottom of the guide plate 51, and the spray port of the spray head 52 intersects with the transmission path of the airflow in the cleaning box 42. The spray head 52 sprays the cleaning liquid in the cleaning box and contacts the flue gas, so that the contaminants in the flue gas are transferred to the cleaning liquid in the cleaning box after contacting the flue gas. At the same time, the guide plate 51 causes the cleaning liquid to flow back. After the cleaning liquid contacts the bottom of the guide plate 51, the cleaning liquid with contaminants is transferred back to the cleaning box under the drive of its own gravitational potential energy, thereby further reducing the contaminants in the flue gas, reusing the cleaning liquid multiple times, improving the utilization rate of the cleaning liquid, and thus saving the cleaning liquid.

[0046] A support plate 32, a brush 34, a lifting member 7, a filter plate 35, a rotating shaft 36, a vertical shaft 38 and a fan blade 39 are installed in the cleaning barrel 3. The lifting member 7 includes a lifting cylinder 71 and a lifting rod 72. The vertically arranged support plate 32 is located at the bottom of the cleaning barrel 3, and the bottom of the support plate 32 is fixedly connected to the top of the transfer plate 24. The side wall of the support plate 32 is fixedly connected to the inner side wall of the cleaning barrel 3. A support groove 33 is formed at the top of the support plate 32, and the support groove 33 is vertically arranged. There are two brushes 34, and the two brushes 34 are respectively located on both sides of the support plate 32. One side of each brush 34 is fixedly connected to the top of the support plate 32, and the other side of each brush 34 contacts the side wall of the filter plate 35. The lifting cylinder 71 is located in the support groove 33, and the cylinder body of the lifting cylinder 71 is fixedly connected to the bottom wall of the support groove 33. The piston rod of the lifting cylinder 71 is vertically upward, and the piston rod of the lifting cylinder 71 is coaxially fixedly connected to the lifting rod 72. The top of the vertically arranged lifting rod 72 is fixedly connected to the bottom of the filter plate 35. The bottom of the vertically arranged filter plate 35 is located in the support groove 33, and the top of the filter plate 35 extends out of the support groove 33, and the side wall of the filter plate 35 contacts the side wall of the support groove 33. The vertically arranged rotating shaft 36 is located at the top of the filter plate 35, and the bottom of the rotating shaft 36 is rotationally connected to the top of the filter plate 35 through a bearing. A vertical groove 37 is coaxially formed at the top of the rotating shaft 36, and the vertical groove 37 is vertically arranged. The vertically arranged vertical shaft 38 is located at the top of the rotating shaft 36, and the vertical shaft 38 is coaxially arranged with the rotating shaft 36. The bottom of the vertical shaft 38 extends into the vertical groove 37 and contacts the side wall of the vertical groove 37. The top of the vertical shaft 38 is fixedly connected to the top wall of the cleaning barrel 3. The horizontally arranged fan blade 39 is sleeved on the rotating shaft 36, and the fan blade 39 is coaxially fixedly connected to the rotating shaft 36. After the flue gas is transmitted from the connecting pipe 22 into the cleaning barrel 3, due to the fast flow rate of the flue gas, the fan blade 39 on the rotating shaft 36 is driven to rotate synchronously. At the same time, when one of the two adsorption pipes 13 operates, the staff starts the lifting cylinder 71. The lifting and lowering of the piston rod of the lifting cylinder 71 drives the lifting rod 72 to lift and lower synchronously, thereby driving the filter plate 35 to move synchronously until the filter plate 35 is lifted to the set height. At this time, driven by the flue gas, the dirt in the flue gas is transmitted to one side of the filter plate 35. When the staff operates the other adsorption pipe 13, driven by the flue gas, the other side of the filter plate 35 contacts the flue gas. Driven by the flue gas, the filter plate 35 is reversely flushed, so that the dirt on one side of the filter plate 35 is separated from the filter plate 35. At the same time, through the cleaning action of the brush 34, the dirt on the filter plate 35 is further reduced. This process is repeated continuously, thereby reducing the dirt on the filter plate 35.

[0047] Inside the cleaning bucket 3, a signal source 81, a receiver 82, a counter 83, a controller 84 and a signal lamp 85 are installed. The signal source 81 is located on the top wall of the cleaning bucket 3 and is used to emit signals. The receiver 82 is located at the bottom of the cleaning bucket 3 and is used to receive the signals emitted by the signal source 81. The fan blade 39 is used to block the signals emitted by the signal source 81 from being received by the receiver 82. The counter 83 is located on one side of the receiver 82 and is connected to the receiver 82. The counter 83 is used to count up the number of times the fan blade 39 blocks the signals transmitted from the signal source 81 to the receiver 82. The controller 84 is located on one side of the counter 83 and is connected to the counter 83. When the number on the counter 83 is less than the set number, that is, when the dirt blocks the cleaning hole 31 on the cleaning bucket 3, resulting in a decrease in the speed of the flue gas entering the cleaning bucket 3, which causes a decrease in the rotation speed of the fan blade 39, and further causes a decrease in the number of times the fan blade 39 blocks the signals emitted by the signal source 81 from being received by the receiver 82 within the set time. Until the number is lower than the set value, the controller 84 sends out a control signal to make the signal lamp 85 light up, thereby reminding the staff to clean the cleaning bucket 3.

[0048] The working principle of the present utility model is as follows:

[0049] When the small combined high-efficiency welding fume absorption and purification device of this embodiment is in use, the staff first adjusts the adsorption pipe 13 so that the magnetic part 14 on the adsorption pipe 13 is magnetically connected to the workpiece 15, so that the nozzle of the adsorption pipe 13 faces the workpiece 15, without the staff having to hold the nozzle of the adsorption pipe 13, which is convenient for the staff to process the workpiece 15 and saves time and effort. The staff then starts the vacuum pump 61. The flue gas generated during the processing of the workpiece 15 is transmitted to the connection box 21 after passing through the adsorption pipe 13, and is initially cleaned and filtered by the cleaning liquid in the connection box 21, and then passes through the cleaning hole 31 after passing through the connecting pipe 22 and is transmitted into the cleaning bucket 3. The flow of the flue gas drives the fan blade 39 to rotate synchronously. Then, under the drive of the vacuum pump 61, the flue gas moves in the vertical direction, passes through the one-way valve 41 and is transmitted into the cleaning box 42, so that the flue gas contacts the cleaning liquid in the cleaning box 42. The cleaning liquid in the cleaning box 42 cleans and filters the flue gas again, further reducing the dirt in the flue gas. At the same time, the cleaning liquid sprayed by the spray head 52 in the cleaning box 42 contacts the flue gas again, further reducing the dirt in the flue gas. Until the flue gas meets the set requirements, it is discharged after passing through the air outlet hole 11 in the adsorption box 1.

[0050] When the fan blade 39 rotates, the fan blade 39 blocks the signals emitted by the signal source 81 to the receiver 82. The counter 83 counts the number of times the fan blade 39 blocks the signals emitted by the signal source 81 from being transmitted to the receiver 82 within the set time. When the number on the counter 83 is lower than the set value, the controller 84 sends out a control signal to make the signal lamp 85 light up, thereby reminding the staff to clean the cleaning bucket 3.

[0051] When the vacuum pump 61 is running, the staff starts the lifting cylinder 71. The lifting and lowering of the piston rod of the lifting cylinder 71 drives the lifting rod 72 to lift and lower synchronously, thereby driving the filter plate 35 to lift and lower synchronously. At this time, the brush 34 contacts the side wall of the filter plate 35, so that the dirt on the filter plate 35, driven by the brush 34, is separated from the filter plate 35 and transmitted to the transmission plate 24, and finally transmitted into the collection box 23. At the same time, when the adsorption pipe 13 on one side of the adsorption box 1 is running, that is, the adsorption pipe 13 on one side of the adsorption box 1 adsorbs the flue gas, and the adsorption pipe 13 on the other side of the adsorption box 1 is not running, that is, when the adsorption pipe 13 on the other side of the adsorption box 1 does not adsorb, the dirt in the flue gas is likely to remain on the side of the cleaning bucket 3 close to the running adsorption pipe 13 and the side of the filter plate 35 close to the running adsorption pipe 13. When the dirt accumulates, the staff makes the adsorption pipe 13 on one side not run, while the adsorption pipe 13 on the other side runs. Driven by the flue gas, the flue gas blows the cleaning bucket 3 and the filter plate 35, so that the flue gas performs a reverse flushing on the side of the cleaning bucket 3 and the filter plate 35 away from the running adsorption pipe 13, so that the dirt on the side of the cleaning bucket 3 and the filter plate 35 away from the running adsorption pipe 13 is separated. After passing through the gap between the transmission plates 24, it is then transmitted into the collection box 23, so as to facilitate the staff to process the dirt in the flue gas.
