Description

Technical Field

[0001] The invention relates to the technical field of submerged arc welding machines, in particular to a submerged arc welding machine with a fume purification function. Background Art

[0002] Submerged arc welding machine is a kind of efficient and automated welding equipment, which is widely used in steel structure manufacturing, shipbuilding, pipeline engineering and other fields. The following is a detailed introduction to the background technology of submerged arc welding machine. Submerged arc welding machine uses the arc to burn under the flux layer, and feeds the welding wire into the welding area through the automatic wire feeding system to realize the automation of the welding process. During the welding process, the flux covers the arc to play a protective role, preventing the oxygen and nitrogen in the air from polluting the molten pool, thereby ensuring the quality of the weld.

[0003] When a submerged arc welding machine is welding, the welding wire, flux and base material will partially evaporate under the action of the high-temperature arc, forming metal vapor and flux vapor. The fume also contains metal dust and toxic gases. Because the fume is generated by welding, the fume itself has a high temperature and may also contain electric sparks. Long-term inhalation of fume by workers will cause health problems. Summary of the invention

[0004] The object of the present invention is to provide a submerged arc welding machine with a fume purification function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A submerged arc welding machine with a fume purification function comprises a body assembly and a welding gun. The body assembly is provided with a suction assembly, which is used to absorb the fume generated by welding. The output end of the suction assembly is provided with a dust removal assembly, which is used to process particles in the fume. A detection assembly is provided on one side of the welding head, which is used to detect the temperature of the welding head.

[0007] Specifically, the submerged arc welding machine as a whole is composed of a welding power supply, a welding gun and a traveling trolley, wherein the traveling trolley is hung with a control box and a wire feeding reel. The above structures are all existing technologies. During the welding process of the submerged arc welding machine, the welding wire, flux and base material will partially evaporate under the action of the high-temperature electric arc to form metal vapor and flux vapor. The flue gas also contains metal dust and toxic gases. Because the flue gas is generated by welding, the flue gas itself has a high temperature and may also contain electric sparks. Therefore, long-term inhalation of fume by workers will lead to respiratory diseases, lung cancer and other health problems. The smoke suction component collects the flue gas through negative air pressure, and then purifies the flue gas internally. The dust removal component is used to clean the dust in the flue gas. The detection component is used to detect the temperature of the welding gun during welding, thereby controlling the operation of the smoke suction component.

[0008] The body assembly includes a traveling trolley and a welding power source. The traveling trolley is provided with a wire feeding motor and a control device. The chassis of the traveling trolley is provided with a smoking assembly. The welding power source is electrically connected to the control device, and the welding power source is electrically connected to the welding gun.

[0009] Specifically, the walking trolley in the prior art is mostly composed of a pulley, a chassis and a support rod, and the overall device is a movable structure. Since the smoking component is installed on the chassis, the position of the smoking component is controlled by the staff.

[0010] The smoking assembly comprises an air suction hood and a fan, the fan is fixedly connected to the chassis of the walking trolley, a bin body is arranged at the input end of the fan, an air suction hood is arranged on the side of the bin body away from the fan, and activated carbon is arranged in the bin body.

[0011] Specifically, the smoking component mainly uses negative air pressure to induce air flow, thereby achieving the purpose of collecting smoke, wherein the suction hood is used to collect smoke and exhaust gas together to prevent diffusion, the bin body is used as a buffer space for smoke to enter, and the particulate matter and harmful gases in the smoke are cleaned in the buffer space, wherein activated carbon is used for purification, and the molecules in the air are captured through the porous structure of the activated carbon, so that an adsorption film is formed on the surface of the activated carbon, thereby effectively collecting harmful gases.

[0012] The activated carbon is located at one end of the bin body close to the fan. Electric contact blocks are arranged on both sides of the activated carbon. The electric contact blocks are fixedly connected to the inner wall of the bin body, and the electric contact blocks are electrically connected to the activated carbon.

[0013] Specifically, the activated carbon is close to the fan and is used as the last step to collect harmful gases in the air. Then the electric contact block is electrically connected to the external power supply. When the activated carbon absorbs harmful gases, more and more adsorption films will appear on the activated carbon, so that the volume of the activated carbon will increase. The electric contact blocks are located at both ends of the activated carbon and are used to measure the resistance value of the activated carbon. The volume of the activated carbon is proportional to the measured resistance value, so the adsorption amount of the activated carbon can be known by the resistance value.

[0014] The dust removal component comprises a cathode needle and an anode plate. The cathode needle is located in the bin body and is fixedly connected to the inner wall of the bin body. The anode plate is located on a side of the inner wall of the bin body away from the cathode needle.

[0015] Specifically, the dust removal component is used to collect and process particulate matter in the flue gas, and the particulate matter is all metal dust. The cathode needle is used to ionize the gas through the electric field generated by the high-voltage DC power supply to generate a large number of electrons and ions. The ionized electrons and ions collide with the dust particles, and the charged dust particles move toward the electrode of opposite polarity under the action of the electric field force, and the negatively charged dust particles move toward the anode plate. After the charged dust particles reach the electrode, they release the charge and deposit on the electrode, thereby realizing the separation of dust and gas. If the particulate matter is not processed, the particulate matter will adhere to the surface of the activated carbon or block its pores, reducing the effective adsorption area of ​​the activated carbon. The particulate matter will accelerate the wear of the activated carbon, thereby the dust removal component increases the service life of the activated carbon.

[0016] The detection component includes a temperature sensing element and a protective cover. The protective cover is located on one side of the welding gun and is fixedly connected to the outer shell of the welding gun. The temperature sensing element is located inside the protective cover. Lead wires are provided at both ends of the temperature sensing element and are electrically connected to the temperature sensing element.

[0017] Specifically, the detection component is used to detect the welding gun, and to know the working temperature and working time of the welding gun. The principle is that the temperature sensing element changes due to the influence of temperature. The leads at both ends of the temperature sensing element are electrically connected to the external power supply. Therefore, when the temperature becomes higher, the resistance value of the temperature sensing element will become higher. The resistance and temperature are linearly related. The working time is judged according to the resistance value, and the operation of the fan is controlled. The protective cover is used to protect highly sensitive components from external influences.

[0018] A flow channel pipe is sleeved on the outer wall of the bin body, the flow channel pipe is fixedly connected to the bin body, and a coolant flows in the flow channel pipe.

[0019] Specifically, the welding gun will generate smoke when working. The smoke has high temperature. If it is not treated, it will easily have irreversible effects on the activated carbon, including the reduction of the adsorption capacity of the activated carbon and the possible change of the pore structure of the activated carbon, which will cause the pores of the activated carbon to expand or collapse, and reduce the adsorption capacity. Since the activated carbon is located on the side of the bin body away from the input end, the smoke needs to pass through the entire bin body to reach the activated carbon. During the movement of the smoke, the heat of the smoke itself will be absorbed by the bin body, and the heat of the bin body itself will be affected by the coolant in the flow channel tube, and finally the coolant will cool the smoke. Therefore, the low-temperature smoke will also reduce the temperature of the activated carbon itself. The low-temperature activated carbon will improve the adsorption capacity because the thermal motion of molecules slows down at low temperatures, and gas molecules are more easily captured by the adsorption sites on the surface of the activated carbon. Moreover, under low temperature conditions, the pore structure of the activated carbon usually remains stable, the desorption ability is weakened, and it is more difficult for gas molecules to release it.

[0020] Springs are provided at both ends of the anode plate, one end of the spring is fixedly connected to the anode plate, and the other end of the spring is fixedly connected to the inner wall of the warehouse body. A rotating motor is provided on the inner wall of the warehouse body, and the fixed end of the rotating motor is fixedly connected to the inner wall of the warehouse body. A cam is provided at the output end of the rotating motor, and the cam is located between the anode plate and the warehouse body.

[0021] Specifically, the spring is used to fix the anode plate on the inner wall of the bin and provide elastic potential energy. The rotating motor is then used as a power source to control the rotation of the cam. Because the cam is located between the bin and the anode plate, when the rotating motor rotates, the cam will continuously generate thrust on the anode plate, causing the anode plate to vibrate. When the anode plate adsorbs particulate matter, the particulate matter is caused to move slowly to the lower end of the horizontal line on the surface of the anode plate through vibration, thereby preventing the particulate matter from concentrating on the anode plate and reducing the adsorption efficiency.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the smoking component generates negative pressure through the fan to induce air flow, thereby achieving the purpose of collecting smoke, wherein the bin is used to move the smoke in the cavity, and the working amplitude of the fan is related to the resistance value of the temperature sensing element, and the two are proportional.

[0024] 2. In the present invention, when the flue gas enters the bin body, the flue gas will contact the activated carbon under the guidance of the fan, and the activated carbon will adsorb harmful gases in the flue gas. Before that, the coolant in the flow channel tube will cool down the bin body as a whole, and the bin body will cool down the flue gas, thereby reducing the impact of high-temperature flue gas on the activated carbon, and the low temperature environment also improves the adsorption performance of the activated carbon.

[0025] 3. In the present invention, the dust removal component generates a high-voltage DC power supply through the cathode needle to ionize the gas. The ionized electrons and ionized particles collide with the dust particles, and the charged dust particles move toward the electrode of opposite polarity under the action of the electric field force, and the negatively charged dust particles move toward the anode plate, thereby filtering out the particulate matter from the flue gas and avoiding subsequent clogging of the activated carbon pores.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0035] Example: Figure 1 to Figure 7 As shown, the present invention provides a technical solution for a submerged arc welding machine with a fume purification function. The submerged arc welding machine includes a body component 1 and a welding gun 2. The body component 1 is provided with a suction component 3, which is used to absorb the fume generated by welding. The output end of the suction component 3 is provided with a dust removal component 4, which is used to process particles in the fume. A detection component 5 is provided on one side of the welding head, which is used to detect the temperature of the welding head.

[0036] Specifically, the submerged arc welding machine as a whole is composed of a welding power source 12, a welding gun 2 and a traveling trolley 11, wherein the traveling trolley 11 is hung with a control box and a wire feeding reel. The above structures are all prior arts. During the welding process of the submerged arc welding machine, the welding wire, flux and base material will partially evaporate under the action of the high-temperature electric arc to form metal vapor and flux vapor. The flue gas also contains metal dust and toxic gases. Because the flue gas is generated by welding, the flue gas itself has a high temperature and may also contain electric sparks. Therefore, long-term inhalation of the flue gas by the staff will lead to respiratory diseases, lung cancer and other health problems. The smoking component 3 collects the flue gas through negative air pressure and then purifies the flue gas internally. The dust removal component 4 is used to clean the dust in the flue gas. The detection component 5 is used to detect the temperature of the welding gun 2 during welding, thereby controlling the operation of the smoking component 3.

[0037] like Figure 1 , Figure 2As shown, the fuselage assembly 1 includes a traveling trolley 11 and a welding power source 12. The traveling trolley 11 is provided with a wire feeding motor 13. The traveling trolley 11 is also provided with a control device. A smoking assembly 3 is provided on the chassis of the traveling trolley 11. The welding power source 12 is electrically connected to the control device, and the welding power source 12 is electrically connected to the welding gun 2.

[0038] Specifically, the walking trolley 11 in the prior art is mostly composed of a pulley, a chassis and a support rod, and the entire device is a movable structure. Since the smoking component 3 is installed on the chassis, the position thereof is controlled by a staff member.

[0039] like Figure 2 to Figure 6 As shown, the smoking assembly 3 includes an air suction hood 31 and a fan 32. The fan 32 is fixedly connected to the chassis of the walking trolley 11. A bin 33 is provided at the input end of the fan 32. The air suction hood 31 is provided on the side of the bin 33 away from the fan 32. Activated carbon 34 is provided in the bin 33.

[0040] Specifically, the smoking component 3 mainly drives the air flow through negative air pressure, so as to achieve the purpose of collecting smoke, wherein the suction hood 31 is used to collect smoke and exhaust gas together to prevent diffusion, and the bin body 33 is used as a buffer space for smoke to enter, and the particulate matter and harmful gases in the smoke are cleaned in the buffer space, wherein the activated carbon 34 is used for purification, and the molecules in the air are captured by the porous structure of the activated carbon 34, so that an adsorption film is formed on the surface of the activated carbon 34, thereby effectively collecting harmful gases.

[0041] like Figure 3 , Figure 6 As shown, the activated carbon 34 is located inside the bin body 33 at one end close to the fan 32 , and electric contact blocks 35 are provided on both sides of the activated carbon 34 . The electric contact blocks 35 are fixedly connected to the inner wall of the bin body 33 , and the electric contact blocks 35 are electrically connected to the activated carbon 34 .

[0042] Specifically, the activated carbon 34 is close to the fan 32 and is used as the last step to collect harmful gases in the air. Then the electric contact block 35 is electrically connected to the external power supply. When the activated carbon 34 absorbs harmful gases, more and more adsorption films will appear on the activated carbon 34, so that the volume of the activated carbon 34 will increase. The electric contact blocks 35 are located at both ends of the activated carbon 34 and are used to measure the resistance value of the activated carbon 34. The volume of the activated carbon 34 is proportional to the measured resistance value, so the adsorption amount of the activated carbon 34 can be known by the size of the resistance value.

[0043] like Figure 3 to Figure 5 As shown, the dust removal assembly 4 includes a cathode needle 41 and an anode plate 42 . The cathode needle 41 is located in the bin body 33 . The cathode needle 41 is fixedly connected to the inner wall of the bin body 33 . The anode plate 42 is located on a side of the inner wall of the bin body 33 away from the cathode needle 41 .

[0044] Specifically, the dust removal component 4 is used to collect and process particulate matter in the flue gas, and the particulate matter is all metal dust, wherein the cathode needle 41 is used to ionize the gas through the electric field generated by the high-voltage DC power supply, generating a large number of electrons and ions, and the ionized electrons and ions collide with the dust particles, and the charged dust particles move toward the electrode of opposite polarity under the action of the electric field force, and the negatively charged dust particles move toward the anode plate 42. After the charged dust particles reach the electrode, they release the charge and deposit on the electrode, thereby realizing the separation of dust and gas. If the particulate matter is not processed, the particulate matter will adhere to the surface of the activated carbon 34 or block its pores, reducing the effective adsorption area of ​​the activated carbon 34. The particulate matter will accelerate the wear of the activated carbon 34, so that the dust removal component 4 increases the service life of the activated carbon 34.

[0045] like Figure 1 , Figure 7 As shown, the detection component 5 includes a temperature sensing element 51 and a protective cover 52. The protective cover 52 is located on one side of the welding gun 2. The protective cover 52 is fixedly connected to the outer shell of the welding gun 2. The temperature sensing element 51 is located in the protective cover 52. Leads are provided at both ends of the temperature sensing element 51, and the leads are electrically connected to the temperature sensing element 51.

[0046] Specifically, the detection component 5 is used to detect the welding gun 2 to obtain the working temperature and working time of the welding gun 2. The principle is that the temperature sensing element 51 changes due to the influence of temperature. The leads at both ends of the temperature sensing element 51 are electrically connected to the external power supply. Therefore, when the temperature becomes higher, the resistance value of the temperature sensing element 51 will become higher. The resistance is linearly related to the temperature. The working time is judged according to the resistance value, and the operation of the fan 32 is controlled. The protective cover 52 is used to protect highly sensitive components from external influences.

[0047] like Figure 2 , Figure 3 As shown, the outer wall of the warehouse body 33 is provided with a flow channel tube 6, and the flow channel tube 6 is fixedly connected to the warehouse body 33, and the flow channel tube 6 is used for the flow of cooling liquid.

[0048] Specifically, the welding gun 2 generates smoke when working. The smoke has a high temperature. If it is not treated, it is easy to have irreversible effects on the activated carbon 34, including a reduction in the adsorption capacity of the activated carbon 34 and a possible change in the pore structure of the activated carbon 34, resulting in the expansion or collapse of the pores of the activated carbon 34, thereby reducing the adsorption capacity. Since the activated carbon 34 is located on the side of the bin body 33 away from the input end, the smoke needs to pass through the entire bin body 33 to reach the activated carbon 34. During the movement of the smoke, its own heat will be absorbed by the bin body 33, and the heat of the bin body 33 itself will be affected by the coolant in the flow channel tube 6, and finally the coolant will cool the smoke. Therefore, the low-temperature smoke will also reduce the temperature of the activated carbon 34 itself. The low-temperature activated carbon 34 will improve the adsorption capacity because the thermal motion of molecules slows down at low temperatures, and gas molecules are more easily captured by the adsorption sites on the surface of the activated carbon 34. Moreover, under low temperature conditions, the pore structure of the activated carbon 34 usually remains stable, the desorption capacity is weakened, and it is more difficult for gas molecules to release it.

[0049] like Figure 4 As shown, springs 43 are provided at both ends of the anode plate 42, one end of the spring 43 is fixedly connected to the anode plate 42, and the other end of the spring 43 is fixedly connected to the inner wall of the warehouse body 33. A rotating motor 44 is provided on the inner wall of the warehouse body 33, and the fixed end of the rotating motor 44 is fixedly connected to the inner wall of the warehouse body 33. A cam 45 is provided at the output end of the rotating motor 44, and the cam 45 is located between the anode plate 42 and the warehouse body 33.

[0050] Specifically, the spring 43 is used to fix the anode plate 42 on the inner wall of the bin body 33 and provide elastic potential energy. The rotating motor 44 is then used as a power source to control the rotation of the cam 45. Since the cam 45 is located between the bin body 33 and the anode plate 42, when the rotating motor 44 rotates, the cam 45 will continuously generate thrust on the anode plate 42, causing the anode plate 42 to vibrate. When the anode plate 42 adsorbs particulate matter, the particulate matter is slowly moved to the lower end of the horizontal line on the surface of the anode plate 42 through vibration, thereby preventing the particulate matter from concentrating on the anode plate 42 and causing the adsorption efficiency to decrease.

[0051] Working principle: During the welding process, the welding torch 2 generates high temperature, and the temperature sensing element 51 is affected by the temperature change. The resistance of the temperature sensing element 51 will increase as the temperature increases, and the fan 32 will also improve the working efficiency as the resistance value of the temperature sensing element 51 increases. When the smoke enters the warehouse body 33 through the suction hood, the coolant in the flow channel pipe 6 will absorb the temperature of the warehouse body 33 to cool the smoke in the warehouse body 33. The smoke will first pass through the dust removal component 4, and the dust removal component 4 will generate a high-voltage DC power supply through the cathode needle 41 to ionize the gas. The ionized electrons and ionized particles collide with the charged dust particles. Under the action of the electric field force, the particles move toward the electrode of opposite polarity, and the negatively charged dust particles move toward the anode plate 42, thereby screening out the particulate matter from the flue gas. Then, the flue gas after the particulate matter treatment will flow to the activated carbon 34, and the activated carbon 34 will adsorb the harmful gases in the flue gas. Before that, the coolant in the flow channel tube 6 will cool down the entire bin body 33, and the bin body 33 will cool down the flue gas, thereby reducing the impact of high-temperature flue gas on the activated carbon 34, and the low temperature environment also improves the adsorption performance of the activated carbon 34, and the electric contacts 35 at both ends of the activated carbon 34 are used to detect the volume of the activated carbon 34.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
