Description

Technical Field

[0001] The present invention mainly relates to the technical field of argon gas recovery and dust removal, and specifically to a conveniently replaceable argon gas recovery and dust removal filtering device. Background Art

[0002] Argon is an inert gas with high density and low thermal conductivity. Generally, cemented carbide manufacturers and manufacturers of high-quality precision ceramic products use high-purity argon for dewaxing (degumming), pressure sintering and cooling processes. As a protective gas, high-purity argon can greatly improve the output and quality of products. In addition, a large amount of argon is also needed in argon arc welding. With the improvement of industrial level, the demand for high-purity argon is also increasing. The argon emitted by various argon equipment is also increasing, resulting in an increase in wasted resources, so argon needs to be recycled and reused.

[0003] After the argon is used and recovered, the argon contains dust because it is in contact with the outside world. To ensure the purity of the argon, the argon needs to be dusted and filtered. Existing argon dust removal and filtration generally uses a filter, that is, one or more filter screens are set in the filter to remove dust from the argon passing through the filter; and the single-structure filter screen often requires shutdown for maintenance when the filter screen is blocked to remove dust on the filter screen. The shutdown for maintenance will greatly reduce the efficiency of argon filtration, especially for continuous production. Frequent shutdowns for maintenance greatly affect the processing efficiency of argon recovery. Summary of the invention

Specifically, the present invention mainly provides a conveniently replaceable argon gas recovery dust removal and filtering equipment to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0009] Two first air nozzles are arranged on one side of the partition, and the two first air nozzles are respectively located on the inner and outer sides of the circular filter. Two second air nozzles opposite to the first air nozzles are arranged on the other side of the partition, and the first air nozzle and the second air nozzle are each connected to an air bag.

[0010] Preferably, both of the air outlet channels are equipped with valves.

[0011] Preferably, a bracket is installed inside the T-channel, and a blocking block is installed on the bracket, and the blocking block is located inside the guide tube.

[0012] Preferably, each of the ring grooves is provided with a circular ring rotating plate located at the groove bottom and a piston ring plate at the groove opening, and a telescopic rod is connected between the circular ring rotating plate and the piston ring plate.

[0013] Preferably, one end of the two ring grooves is commonly connected to a receiving groove, and a dual-axis motor is arranged inside the receiving groove, and driving gears are respectively installed at the output ends of the dual-axis motor, and each of the driving gears is meshed with a gear ring, and the gear ring is sleeved on the outer wall of the circular rotating plate.

[0014] Preferably, an adjustment groove is provided on the side of the guide tube away from its lateral inlet, and piston plates are slidably installed at both ends of the adjustment groove. A connecting rod is connected between the two piston plates, and the connecting rod is connected to the guide tube through a fixed frame. A rack is installed on one side of the connecting rod, and the rack is meshed with an adjustment gear. The two ends of the adjustment groove are connected through a ventilation pipe and the inside of two annular grooves.

[0015] Preferably, an air pressure groove is provided inside the partition, the two first air nozzles are connected to the air pressure groove through an air pipeline, the two second air nozzles are connected to the air pressure groove through an air pipeline, a rotating gear is rotatably installed on one side of the air pressure groove, a one-way air inlet pipe and a one-way air outlet pipe are installed on the rotating gear, a driving gear is meshed on one side of the rotating gear, and a first handle rod connected to the axis of the driving gear is provided outside the partition.

[0016] Preferably, a second handle rod is provided outside the partition, the second handle rod passes through the compressed air groove and extends to the inside of the adjusting groove, and is connected to the axis of the adjusting gear. A disc is provided inside the compressed air groove, and the second handle rod drives the disc to rotate through two mutually meshing bevel gears. A suction and pressure piston is slidably installed inside the adjusting groove, and a transmission rod is rotatably connected between the suction and pressure piston and the eccentric position of the disc.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) Argon gas with dust enters the T-channel through the air inlet. Since the opening at one end of the guide tube is blocked by the blocking block, the argon gas with dust will only come out from one end of the guide tube. After long-term use, when the annular filter is blocked and needs to be replaced, it is only necessary to move the guide tube so that the blocking block blocks the opening at the other end of the guide tube, and the previously blocked opening of the guide tube is opened, so that the argon gas with dust can flow to the other side of the partition and be filtered by another annular filter, thereby realizing the replacement of the filter without stopping the machine.

[0019] (2) After long-term use, when the annular filter is blocked and needs to be replaced, the drive adjustment gear is rotated. The rotation of the adjustment gear will drive the rack to move, and the rack drives the connecting rod to move. The guide tube follows the connecting rod through the fixed frame. At the same time, the connecting rod drives the two piston plates to move. The two piston plates move synchronously, which will inflate the inside of one of the ring grooves. The piston ring plate moves and pushes the annular filter. The annular filter is tightly clamped between the piston ring plate and the rotating ring to avoid poor air tightness of the annular filter when filtering argon due to loose installation of the annular filter, thereby reducing the argon filtration purity. The gas in the other ring groove flows to the adjustment groove, so that the piston ring plate no longer presses tightly against the annular filter, which facilitates the replacement of the annular filter.

[0020] (3) The dual-axis motor drives the driving gear to rotate, and the driving gear drives the gear ring to rotate so that the circular rotating plate rotates. The circular rotating plate drives the piston ring plate to rotate through the telescopic rod. Since the circular filter is tightly pressed between the piston ring plate and the rotating circular ring, the piston ring plate drives the circular filter to rotate. Since the positions of the exhaust port and the outlet of the guide tube are fixed, the flow direction of the argon gas flow is also fixed. If the circular filter is fixed, the argon gas flow will always pass through the same place of the circular filter, resulting in serious local blockage of the circular filter. The circular filter is not fully used, affecting the argon gas filtration efficiency. Since the circular filter in the present device rotates slowly, the circular filter can be fully used to avoid local blockage of the circular filter and ensure the argon gas filtration efficiency.

[0021] (4) When the annular filter in the filtering space needs to be replaced after being used for a long time, first turn the first handle bar, the first handle bar drives the driving gear to rotate, so that the rotating gear rotates half a circle, the one-way air inlet pipe and the one-way air outlet pipe are displaced, and the gas flow direction inside the compressed air groove and the air bag is changed. Then turn the second handle bar, the second handle bar drives the disc to rotate, and the disc drives the pumping and pressing piston to move up and down through the transmission rod. At the same time, due to the change in the outlet direction of the guide tube, argon gas stops entering the filtering space, and argon gas enters the space to be used. The squeezing of argon gas and the up and down movement of the pumping and pressing piston cause the air bag in the filtering space to expand, and the air bag in the space to be used to shrink. Due to the expansion of the air bag, the argon gas remaining in the filtering space will be quickly squeezed out, avoiding argon gas residue, reducing resource consumption, and avoiding argon gas leakage.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0038] Please refer to the attached pictures Figure 1 As shown, a conveniently replaceable dust removal and filtering device for argon recovery includes a filter 1, wherein the filter 1 includes a filter channel 101, and detachably mounted sealing cover plates 102 are respectively arranged at both ends of the filter channel 101, an air inlet channel 103 is arranged at the center of one side of the filter channel 101, and air outlet channels 104 are respectively arranged at both ends of the other side of the filter channel 101, and both air outlet channels 104 are respectively provided with valves.

[0039] Please refer to the attached pictures Figure 1 - Figure 5As shown, a partition 201 is installed at the center of the filter channel 101, and the partition 201 divides the interior of the filter channel 101 into two parts. A T-channel 202 is opened inside the partition 201, and one end of the T-channel 202 is opened and connected to the air inlet channel 103. A guide tube 203 is slidably installed inside the T-channel 202, and a lateral inlet is opened on the side wall of the guide tube 203. The guide tube 203 is connected to the T-channel 202 through the lateral inlet; a bracket is installed inside the T-channel 202, and a blocking block 204 is installed on the bracket, and the blocking block 204 is located inside the guide tube 203. The argon gas containing dust enters the T-channel 202 through the air inlet 103. Since the opening at one end of the guide tube 203 is blocked by the blocking block 204, the argon gas containing dust will only come out from one end of the guide tube 203. After long-term use, when the annular filter 301 is blocked and needs to be replaced, it is only necessary to move the guide tube 203 so that the blocking block 204 blocks the opening at the other end of the guide tube 203, and the previously blocked opening of the guide tube 203 is opened, so that the argon gas containing dust can flow to the other side of the partition 201, and is filtered by another annular filter 301, thereby realizing the replacement of the filter without stopping the machine.

[0040] Please refer to the attached pictures Figure 1 - Figure 5As shown, annular grooves 205 are respectively provided on both sides of the partition 201, an annular filter screen 301 is provided between each sealing cover plate 102 and the partition plate 201, mounting rings 302 are respectively installed at both ends of the annular filter screen 301, a rotating ring 303 is rotatably installed on each sealing cover plate 102, the rotating ring 303 and the annular groove 205 are directly opposite, and the annular filter screen 301 is located between the rotating ring 303 and the annular groove 205; each annular groove 205 is provided with an annular rotating plate 206 located at the bottom of the groove and a piston ring plate 207 at the notch, and a telescopic rod 208 is connected between the annular rotating plate 206 and the piston ring plate 207. An adjusting groove 401 is provided on the side of the guide tube 203 away from its lateral inlet, and piston plates 402 are slidably installed at both ends of the adjusting groove 401, and a connecting rod 403 is connected between the two piston plates 402. The connecting rod 403 is connected to the guide tube 203 through a fixed frame, and a rack 404 is installed on one side of the connecting rod 403. The rack 404 is meshed with an adjusting gear 405, and the two ends of the adjusting groove 401 are connected to the inside of the two annular grooves 205 through a ventilation pipe. After long-term use, when the annular filter 301 is blocked and needs to be replaced, the adjusting gear 405 is driven to rotate. The rotation of the adjusting gear 405 will drive the rack 404 to move, and the rack 404 drives the connecting rod 403 to move. The guide tube 203 follows the connecting rod 403 through the fixed frame, and at the same time the connecting rod 403 drives the two piston plates 402 to move. The two piston plates 402 move synchronously, which will inflate the inside of one of the ring grooves 205, and the piston ring plate 207 moves and pushes the annular filter 301. The annular filter 301 is tightly clamped between the piston ring plate 207 and the rotating ring 303 to prevent the annular filter 301 from reducing the argon filtration purity due to poor upper and lower air tightness when filtering argon. The gas in the other ring groove 205 flows to the adjusting groove 401, so that the piston ring plate 207 no longer presses tightly against the annular filter 301, which facilitates the replacement of the annular filter 301.

[0041] Please refer to the attached pictures Figure 1 - Figure 5As shown, one end of the two ring grooves 205 is connected to a receiving groove, and a dual-axis motor 209 is arranged inside the receiving groove. The output ends of the dual-axis motor 209 are respectively installed with driving gears 210, and each driving gear 210 is meshed with a gear ring, which is sleeved on the outer wall of the circular rotating plate 206. The dual-axis motor 209 drives the driving gear 210 to rotate. The driving gear 210 drives the gear ring to rotate so that the annular rotating plate 206 rotates. The annular rotating plate 206 drives the piston ring plate 207 to rotate through the telescopic rod 208. Since the annular filter 301 is tightly pressed between the piston ring plate 207 and the rotating ring 303, the piston ring plate 207 drives the annular filter 301 to rotate. Since the positions of the exhaust port and the outlet channel 104 of the guide tube 203 are fixed, the flow direction of the argon gas flow is also fixed. If the annular filter 301 is fixed, the argon gas flow will always pass through the same place of the annular filter 301, resulting in serious local blockage of the annular filter 301. The annular filter 301 is not fully used, which affects the argon gas filtering efficiency. However, since the annular filter 301 in the present device rotates slowly, the annular filter 301 can be fully used to avoid local blockage of the annular filter 301 and ensure the argon gas filtering efficiency.

[0042] Please refer to the attached pictures Figure 1 - Figure 6 As shown, two first air nozzles 501 are provided on one side of the partition 201, and the two first air nozzles 501 are respectively located on the inner and outer sides of the circular filter 301, and two second air nozzles 502 opposite to the first air nozzles 501 are provided on the other side of the partition 201, and the first air nozzles 501 and the second air nozzles 502 are each connected to an air bag 504. A compressed air groove 503 is arranged inside the partition 201, two first air nozzles 501 are connected to the compressed air groove 503 through an air pipeline, and two second air nozzles 502 are connected to the compressed air groove 503 through an air pipeline. A rotating gear 505 is rotatably installed on one side of the compressed air groove 503, and a one-way air inlet pipe 506 and a one-way air outlet pipe 507 are installed on the rotating gear 505. The one-way function of the one-way air inlet pipe 506 and the one-way air outlet pipe 507 is provided by a one-way valve. A driving gear 508 is meshed on one side of the rotating gear 505, and a first handle rod 509 connected to the axis of the driving gear 508 is arranged outside the partition 201. A second handle bar 510 is provided outside the partition 201, and the second handle bar 510 passes through the compressed air groove 503 and extends to the inside of the adjusting groove 401, and is connected to the axis of the adjusting gear 405. A disc 511 is provided inside the compressed air groove 503, and the second handle bar 510 drives the disc 511 to rotate through two mutually meshing bevel gears. A suction and pressure piston 512 is slidably installed inside the adjusting groove 401, and a transmission rod is rotatably connected between the suction and pressure piston 512 and the eccentric position of the disc 511.

[0043] The two sides of the partition 201 are the filtering space and the waiting space respectively. The airbag 504 inside the filtering space is in a contracted state, and the airbag 504 inside the waiting space is in an expanded state. Due to the existence of the one-way air inlet pipe 506 and the one-way air outlet pipe 507, the gas flows from the contracted airbag 504 to the compressed air groove 503, and then flows to the expanded airbag 504.

[0044] When the annular filter screen 301 in the filtering space needs to be replaced after being used for a long time, the first handle rod 509 is rotated first, and the first handle rod 509 drives the driving gear 508 to rotate, so that the rotating gear 505 rotates half a circle, the one-way air inlet pipe 506 and the one-way air outlet pipe 507 are displaced, and the gas flow direction inside the compressed air groove 503 and the air bag 504 is changed. Then the second handle rod 510 is rotated, and the second handle rod 510 drives the disc 511 to rotate. The disc 511 drives the pumping and pressing piston 512 to move up and down through the transmission rod. At the same time, due to the change in the outlet direction of the guide tube 203, argon gas stops entering the filtering space, and argon gas enters the space to be used. The squeezing of argon gas and the up and down movement of the pumping and pressing piston 512 make the air bag 504 in the filtering space expand, and the air bag 504 in the space to be used shrinks. Due to the expansion of the air bag 504, the argon gas remaining in the filtering space will be quickly squeezed out to avoid argon gas residue, reduce resource consumption, and avoid argon gas leakage.

[0045] Specific steps:

[0046] The two sides of the partition 201 are respectively the filtering space and the waiting space. The argon gas with dust enters the T-channel 202 through the air inlet 103. Since the opening of the guide tube 203 toward the waiting space is blocked by the blocking block 204, the argon gas with dust will only enter the filtering space. The dual-axis motor 209 drives the driving gear 210 to rotate. The driving gear 210 drives the gear ring to rotate to rotate the annular rotating plate 206. The annular rotating plate 206 drives the piston ring plate 207 to rotate through the telescopic rod 208. Since the annular filter 301 is tightly pressed between the piston ring plate 207 and the rotating annular ring 301, the annular filter 301 is tightly pressed between the piston ring plate 207 and the rotating annular ring 301. 03, therefore, the piston ring plate 207 drives the annular filter 301 to rotate. Since the positions of the exhaust port of the guide tube 203 and the outlet 104 are fixed, the flow direction of the argon gas flow is also fixed. If the annular filter 301 is fixed, the argon gas flow will always pass through the same place of the annular filter 301, resulting in serious local blockage of the annular filter 301, and the annular filter 301 is not fully used, which affects the argon gas filtering efficiency. However, since the annular filter 301 in the present device rotates slowly, the annular filter 301 can be fully used to avoid local blockage of the annular filter 301 and ensure the argon gas filtering efficiency.

[0047] After long-term use, when the annular filter 301 in the filtering space needs to be replaced and maintained, the first handle bar 509 is first rotated, and the first handle bar 509 drives the driving gear 508 to rotate, so that the rotating gear 505 rotates half a circle, and the one-way air inlet pipe 506 and the one-way air outlet pipe 507 are displaced, and the gas flow direction inside the compressed air tank 503 and the air bag 504 is changed;

[0048] Then, the second handle bar 510 is rotated, and the second handle bar 510 drives the adjusting gear 405 to rotate. The adjusting gear 405 rotates and drives the rack 404 to move. The rack 404 drives the connecting rod 403 to move. The guide tube 203 moves along with the connecting rod 403 through the fixing frame. As the guide tube 203 moves, the blocking block 204 blocks the opening of the guide tube 203 toward the filtering space, so that the argon gas with dust enters the space to be used.

[0049] When the connecting rod 403 moves, the two piston plates 402 are driven to move, and the gas inside the ring groove 205 close to the filtering space flows to the regulating groove 401, so that the piston ring plate 207 no longer presses tightly against the annular filter 301, which is convenient for taking and replacing the annular filter 301. When the ring groove 205 close to the space to be used is inflated, the piston ring plate 207 moves and pushes the annular filter 301, and the annular filter 301 is tightly clamped between the piston ring plate 207 and the rotating ring 303, so as to avoid the annular filter 301 from reducing the argon filtration purity due to poor air tightness from top to bottom when filtering argon.

[0050] When the second handle bar 510 rotates, it will drive the disc 511 to rotate. The disc 511 drives the suction and pressure piston 512 to move up and down through the transmission rod. At the same time, due to the change in the outlet direction of the guide tube 203, the argon gas is stopped from entering the filtering space, and argon gas is introduced into the space to be used. The squeezing of the argon gas and the up and down movement of the suction and pressure piston 512 cause the airbag 504 in the filtering space to expand, and the airbag 504 in the space to be used to shrink. Due to the expansion of the airbag 504, the argon gas remaining in the filtering space will be quickly squeezed out to avoid argon gas residue, reduce resource consumption, and avoid argon gas leakage.

[0051] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
