Description

Technical Field

[0001] This invention belongs to the field of sulfur hexafluoride gas recovery technology, specifically relating to an automatic recovery device for sulfur hexafluoride gas. Background Technology

[0002] Sulfur hexafluoride (SF6) gas is widely used in electrical insulation equipment due to its excellent insulating properties and arc-quenching ability. When SF6 gas is used in electrical insulation equipment, different decomposition gases are produced under different fault conditions. Therefore, the operating status of the electrical equipment can be determined by detecting the SF6 gas. Since SF6 is a greenhouse gas, directly releasing SF6 exhaust gas into the environment will cause pollution. Therefore, fully automated SF6 recovery devices are needed to recover and treat the SF6 gas.

[0003] Existing technology CN218794756U discloses a fully automatic SF6 recovery device, including an operating table. A first purification box is fixedly connected to one side of the top of the operating table, and an oil-free compressor is fixedly connected to the other side of the top of the operating table. Support legs are fixedly connected to the four corners of the bottom of the operating table. A support plate is fixedly connected to one side of the bottom of the operating table, and a storage tank is fixedly connected to one side of the support plate. A sealing groove is opened on one side of the front of the first purification box, and a sealing door is snapped into the sealing groove. A fixed frame is fixedly connected to the rear end of the sealing door. Fixing holes are opened on both sides of the sealing groove. A sliding groove is opened on the front of the sealing door, and sliding plates are slidably connected to both sides inside the sliding groove. A pull block is fixedly connected to the front of the sliding plate. A return spring is fixedly connected between the two sliding plates. A fixed rod is fixedly connected to the side of the sliding plate away from the return spring. A limit slot is opened inside the first purification box behind the fixed frame. A second purification box is fixedly connected inside the first purification box to one side of the fixed frame. A zeolite molecular sieve is snapped into the bottom of the fixed frame. When this device recovers SF6 gas, the SF6 gas directly enters the first purification tank without pre-removing dust and other waste from the SF6 gas. This results in excessive dust and other waste entering the first purification tank, which in turn requires the solution in the first purification tank to be replaced in advance, greatly shortening the solution replacement cycle of the first purification tank. Summary of the Invention

[0004] This invention provides an automatic recovery device for sulfur hexafluoride (SF6) gas. Its purpose is to solve the problem that in existing automatic recovery devices for SF6 gas, SF6 gas directly enters the first purification tank without pre-stripping the dust and other waste in the SF6 gas, resulting in excessive dust and other waste entering the first purification tank. Consequently, the solution in the first purification tank needs to be replaced in advance, greatly shortening the solution replacement cycle of the first purification tank.

[0005] This invention provides an automatic recovery device for sulfur hexafluoride gas, comprising an operating table, a first purification box fixedly connected to one side of the top of the operating table, an oil-free compressor fixedly connected to the other side of the top of the operating table, support legs fixedly connected to the four corners of the bottom of the operating table, a support plate fixedly connected to one side of the bottom of the operating table, a storage tank fixedly connected to one side of the support plate, and a waste stripping component installed on the side of the first purification box farther from the oil-free compressor.

[0006] The waste stripping assembly includes an outer barrel and a rotating platform installed between a pair of discs. The pair of discs are fixed in the outer barrel. A pair of assembly frames are movably installed on the outer circumference of the rotating platform. Multiple stripping discs are installed in the assembly frames.

[0007] Also includes:

[0008] The replacement unit is used to smoothly replace a pair of assembly racks. The replacement unit is installed in the outer barrel. The replacement unit includes a barrier strip that is movably installed in the assembly rack. An outer peeling plate is fixed to the outside of the barrier strip and the outside of the assembly rack.

A pair of bending and adjusting strips B are fixed to one side of the barrier strip near the assembly frame. The inside of each pair of bending and adjusting strips A is in contact with the inside of the pair of bending and adjusting strips B. Three evenly arranged deformable parts A are fixed between the inside of the assembly frame and both sides of the barrier strip. The outer wall of the disc has a guide groove for the guide post to move.

[0010] The disassembly and cleaning unit is used to disassemble and clean the assembly rack. The disassembly and cleaning unit is installed at the lower end of the outer barrel. The disassembly and cleaning unit includes a pair of assembly tables fixed to both sides of the assembly rack. The outer wall of the rotating table has a groove for moving the assembly table. A movable piece is movably installed in the groove. A pair of deformable parts B are fixed between the bottom wall of the movable piece and the bottom wall of the groove. A pair of mirror-shaped inserting posts A are fixed to the bottom wall of the assembly table. The inserting posts A can move through the movable piece.

[0011] Furthermore, the switching unit also includes a rotating column fixed to the rotating table near the disc. The guide column is hemispherical on the side farther from the barrier bar. The rotating column is screwed to the outside of the disc. A motor is fixed in the guide tube on the side of the outer barrel. A sprocket is installed on the rotating part of the motor. A sprocket is also installed on the rotating column adjacent to the motor. The pair of sprockets are connected by chain drive.

[0012] Furthermore, the extraction unit also includes an extraction groove reserved at the lower end of the outer barrel, with arched cover plates screwed onto both sides of the extraction groove. The guide groove is deeper than the interlocking groove, and an assembly strip is fixed to one side of the arched cover plate. A pair of assembly strips are fixed together by a tension screw.

[0013] Furthermore, the disassembly and cleaning unit also includes a pair of mirror-mounted insert pins B at the bottom of the movable plate. The outer wall of the insert pin A has a locking opening for insert pin B to engage. The side of insert pin B furthest from insert pin A is fixed to a movable pin. The outer wall of the rotating table has a through-hole for movable pin and insert pin B to move. The bottom of the movable pin and the through-hole is fixed to a deformable component C.

[0014] Furthermore, connectors are fixed to both sides of the outer barrel.

[0015] Furthermore, a silicone sheet is fixed to the inside of the upper part of the outer barrel, and the size of the assembly frame is smaller than that of the silicone sheet.

[0016] Furthermore, a chip is installed on the outside of the outer barrel, and the chip is electrically connected to the motor.

[0017] Furthermore, a silicone strip is fixed to the side of the barrier strip that is farther from the assembly frame, and the outer wall of the silicone strip is in contact with the inner wall of the slot on the rotating table.

[0018] Furthermore, several evenly arranged support columns are fixed inside the bending and adjusting strip A, and the inside of the bending and adjusting strip B has pre-drilled fitting holes to allow the support columns to move.

[0019] Furthermore, a magnet is fixed to the side of the insert post B that is farther away from the variable post.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. In this invention, dust and other impurities in SF6 gas are first removed by a waste stripping component. After the waste stripping process, the SF6 gas is then transported to the first purification tank for purification, thus avoiding excessive waste and shortening the liquid replacement cycle of the first purification tank.

[0022] 2. When the multiple peeling plates need to be replaced, the motor can drive the corresponding rotating column to rotate via the chain, which in turn drives the rotating table to rotate, allowing a pair of multiple peeling plates to exchange positions. The rotating table also drives a pair of assembly frames to rotate together, causing a pair of guide posts on the barrier strip to move out of the interlocking groove. The guide posts can then move along the inside of the disc, and through the movement of the guide posts, the barrier strip applies pressure to the multiple peeling plates, so that the outer peeling plate on the barrier strip is moved inside the assembly frame. This prevents dust and other debris on the outer peeling plate from falling into the outer barrel during the rotation of the barrier strip, allowing the barrier strip to be removed and the dust and other debris on the outer peeling plate to be removed. This achieves the peeling of dust and other debris from SF6 gas and prevents dust and other debris from clogging the peeling openings on the peeling plates.

[0023] 3. When the barrier strip moves, the present invention can pull the bending and changing strip B along the inside of the bending and changing strip B, thereby enhancing the stability of the barrier strip's movement and applying pressure to the deformable part A. When the guide post on the barrier strip is aligned with the guide groove on the circular piece, because the guide groove is deeper than the interlocking groove, the barrier strip moves quickly to the side farther from the multiple peeling pieces, so as to open a pair of arched cover plates to remove the multiple peeling pieces from the assembly frame and insert the unused peeling pieces between the assembly frame and the barrier strip, thereby achieving rapid removal of the peeling pieces and facilitating the replacement of the multiple peeling pieces.

[0024] 4. When using this invention, when the pair of arched covers are opened, the inside of the arched covers can move towards the side farther from the movable column. Under the deformation of the deforming component C, the movable column pulls the interlocking column B out of the engagement port on the interlocking column A, thus releasing the constraint on the interlocking column A. Then, under the deformation of the deforming component B, the movable piece presses the assembly table to move along the groove on the rotating table. The assembly table can quickly pull the assembly frame away from the interlocking interface on the rotating table, so that the assembly frame and the barrier strip can be pulled away from the rotating table, and the assembly frame and the barrier strip can be cleaned. When the pair of arched covers are closed, the wall surface of the arched covers can press the movable column to move, so that the interlocking column B can be interlocked into the engagement port of the interlocking column A, thus constraining the assembly frame. When the rotating table rotates, the movable column can move along the arched covers into the outer barrel, maintaining the pressure on the movable column, thereby achieving rapid assembly and disassembly.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1-9This invention proposes an automatic recovery device for sulfur hexafluoride gas, comprising an operating table (1), a first purification box (2) fixedly connected to one side of the top of the operating table (1), an oil-free compressor (3) fixedly connected to the other side of the top of the operating table (1), support legs (4) fixedly connected to the four corners of the bottom of the operating table (1), a support plate (5) fixedly connected to one side of the bottom of the operating table (1), a storage tank (6) fixedly connected to one side of the support plate (5), an air inlet pipe fixedly connected to one side of the first purification box (2), the other side of the first purification box (2) connected to the oil-free compressor (3) through a pipe, the oil-free compressor (3) connected to the storage tank (6) through a pipe, a recharge pipe fixedly connected to one side of the storage tank (6), and a waste stripping assembly 7 installed on the side of the first purification box (2) farther from the oil-free compressor 3.

[0039] The waste stripping component 7 first removes dust and other impurities from the SF6 gas. After the waste stripping process, the SF6 gas is then transported to the first purification tank 2 for purification, thus avoiding excessive waste and shortening the liquid replacement cycle of the first purification tank 2.

[0040] Reference Figures 2-9 The waste stripping assembly 7 includes an outer barrel 8 and a pair of circular plates 9 mirror-fixed within the outer barrel 8. The outer barrel 8 is cylindrical. A rotating platform 10 is installed between the pair of circular plates 9. The two sides of the rotating platform 10 and the pair of circular plates 9 are in contact with each other. A pair of mirror-shaped mounting brackets 11 are movably mounted on the outer circumference of the rotating platform 10. A pair of interlocking interfaces are reserved on the outer circumference of the rotating platform 10 for the pair of mounting brackets 11 to be fitted together. Multiple stripping plates 12 are installed in the mounting brackets 11. Several stripping openings are reserved on the multiple stripping plates 12. A pair of mirror-shaped guide tubes are fixed within the outer barrel 8. 13. The inner wall of the guide pipe 13 is skewed, and the outer barrel 8 is fixedly connected to the two sides of the connector 35, so that the outer barrel 8 is connected to the first purification box 2 and the SF6 gas delivery pipeline through a pair of connectors 35 respectively; it also includes: a replacement unit, used to smoothly replace a pair of assembly racks 11, the replacement unit is installed in the outer barrel 8; an extraction unit, used to extract the multiple peeling pieces 12 in the assembly rack 11, the extraction unit is installed in the assembly rack 11; and a disassembly and decontamination unit, used to disassemble and decontaminate the assembly rack 11, the disassembly and decontamination unit is installed at the lower end of the outer barrel 8;

[0041] When the multiple peeling plates 12 need to be replaced, the motor 18 can pull the corresponding rotating column 17 to rotate via the chain 19, so that the rotating column 17 pulls the rotating table 10 to rotate, so that the pair of multiple peeling plates 12 can exchange positions, and the rotating table 10 pulls a pair of mounting frames 11 to rotate together, so that a pair of guide posts 16 on the barrier strip 14 can be moved out of the interlocking groove 23, so that the guide posts 16 can move along the inside of the disc 9, and through the movement of the guide posts 16, the barrier strip 14 can press on the multiple peeling plates 12, so as to move the outer peeling plate 15 on the barrier strip 14 into the inside of the mounting frame 11, so as to prevent dust and other debris on the outer peeling plate 15 from falling into the outer barrel 8 during the rotation of the barrier strip 14, so that the barrier strip 14 can be removed, and the dust and other debris on the outer peeling plate 15 can be removed, thereby achieving the peeling of dust and other debris in SF6 gas and preventing dust and other debris from clogging the peeling port on the peeling plate.

[0042] The switching unit includes a barrier strip 14 movably mounted in the assembly frame 11. The outer wall of the barrier strip 14 is in contact with the outer wall of the multiple peeling plate 12. External peeling plates 15 are fixedly connected to both the outside of the barrier strip 14 and the outside of the assembly frame 11. Several peeling openings are provided on the external peeling plates 15, allowing gas to flow through the external peeling plates 15 into the multiple peeling plates 12. The outer surfaces of the disc 9 and the rotating table 10 are both provided with slots that fit the external peeling plates 15. A pair of guide posts 16 are fixedly connected to the side of the barrier strip 14 furthest from the assembly frame 11. A pair of fitting grooves 23 are provided on the outer wall of the disc 9 for the guide posts 16 to engage. The openings of the fitting grooves 23 are arched. The guide post 16 is hemispherical on the side farther from the barrier strip 14 so that the guide post 16 can be moved out of the interlocking groove 23. The rotating table 10 is fixed to the rotating post 17 near the disc 9. The rotating post 17 is screwed to the outside of the disc 9 so that the rotating table 10 faces the pair of discs 9. The motor 18 is fixed in the guide tube 13 on the side of the outer barrel 8. The motor 18 can rotate intermittently. A sprocket is installed on the rotating part of the motor 18. A sprocket is also installed on the rotating post 17 adjacent to the motor 18. The pair of sprockets are connected by a chain 19. The motor 18 pulls the rotating table 10 to perform intermittent rotation through the chain 19 and the rotating post 17.

[0043] The extraction unit includes a pair of mirror-image bent and flexible strips A20 fixed in the assembly frame 11. A pair of mirror-image bent and flexible strips B21 are fixed to one side of the barrier strip 14 near the assembly frame 11. Each of the bent and flexible strips A20 is in contact with the inside of the pair of bent and flexible strips B21, allowing the bent and flexible strips A20 to engage with the bent and flexible strips B21. Three evenly arranged deformable elements A22 are fixed between the inside of the assembly frame 11 and both sides of the barrier strip 14. Through the deformation of the deformable elements A22, the barrier strip 14 adheres to the outer wall of the multiple release plate 12. A guide groove 24 is pre-formed on the outer wall of the disc 9 to allow the guide post 16 to move. The guide groove 24 is concave and deeper than the interlocking groove 23. When the guide post 16 is engaged in the guide groove 24, the barrier strip 14 can release the multiple release plate 12. The lower end of the outer barrel 8 has a pre-reserved extraction slot. The span of the assembly frame 11 is smaller than the span of the extraction slot, which is used to remove the multiple stripping strips 12 from the bottom of the rotating table 10. Both sides of the extraction slot are screwed with arched cover plates 25. One side of the arched cover plate 25 is fixedly connected to an assembly strip 26. A pair of assembly strips 26 are fixedly connected by a tension screw 34 to open or close the arched cover plate 25. A chip 37 is installed on the outside of the outer barrel 8. The chip 37 is electrically connected to the motor 18 to control the movement of the motor 18. The chip 37 and the motor 18 are existing technologies and will not be described in detail here. A silicone sheet 36 is fixedly connected to the inside of the upper end of the outer barrel 8. The size of the assembly frame 11 is smaller than the size of the silicone sheet 36 to enhance the leak-proof performance between the assembly frame 11 and the barrier strip 14 and ensure that the multiple stripping strips 12 can remove dust and other waste from SF6 gas.

[0044] When the barrier strip 14 moves, it can pull the bending deformation strip B21 to move along the inside of the bending deformation strip B21, which enhances the stability of the barrier strip 14 movement and squeezes the deformable part A22. When the guide post 16 on the barrier strip 14 is aligned with the guide groove 24 on the disc 9, because the guide groove 24 is deeper than the interlocking groove 23, the barrier strip 14 moves quickly to the side farther from the multiple peeling strip 12, so as to open a pair of arched cover plates 25 to remove the multiple peeling strip 12 from the assembly frame 11 and insert the unused peeling strip between the assembly frame 11 and the barrier strip 14, thereby realizing the rapid extraction of the peeling strip and facilitating the replacement of the multiple peeling strip 12.

[0045] In use, the outer barrel 8 is assembled onto the first purification box 2 and the SF6 gas delivery pipeline via a pair of connectors 35. When SF6 gas is drawn into the outer barrel 8, it flows through the inclined wall of the guide pipe 13 into the slot of the disc 9. The outer peeling disc 15 and the multiple peeling disc 12, which are directly opposite the slots on the disc 9, peel off dust and other waste from the SF6 gas. Larger particles adhere to the outer peeling disc 15. When the multiple peeling disc 12 needs to be replaced, the chip 37 activates the motor 18. The motor 18 pulls the corresponding rotating column 17 to rotate via the chain 19. The rotating column 17 pulls the rotating table 10 to rotate half a turn, thereby changing the position of the pair of multiple peeling discs 12. The rotating table 10 pulls the barrier strip 14 to rotate via the assembly frame 11, causing the pair of guide posts 16 on the barrier strip 14 to move out of the interlocking groove 23. The guide posts 16 pull the barrier strip 14 along the assembly frame 11. In step 1, the outer peeling piece 15 on the barrier strip 14 is moved into the assembly frame 11, and the barrier strip 14 pulls the bending deformation strip B21 to move along the inside of the bending deformation strip A20, so that the barrier strip 14 firmly squeezes the deformable part A22. When the guide post 16 and the guide groove 24 are aligned, the guide post 16 is embedded in the guide groove 24. Under the deformation of the deformable part A22, the barrier strip 14 moves to the side farther away from the multiple peeling piece 12. Then, the pair of arched cover plates 25 are opened, so that the multiple peeling piece 12 can be pulled out from between the assembly frame 11 and the barrier strip 14, and the assembly frame 11 and the barrier strip 14 can be pulled out from the interface of the rotating table 10 to remove dust and other waste attached to the barrier strip 14. This achieves the purpose of quickly replacing the multiple peeling piece 12 and removing waste, avoiding the blockage problem inside the outer tank 8, and ensuring that SF6 gas can be smoothly delivered for treatment.

[0046] Reference Figures 4-9The disassembly and cleaning unit includes a pair of assembly tables 27 mirror-fixed to both sides of the assembly frame 11. The outer wall of the rotating table 10 has pre-drilled grooves for the assembly tables 27 to move. The assembly tables 27 are smaller than the grooves. A movable piece 28 is movably installed in the grooves. A pair of mirror-fixed deformable parts B29 are fixed between the bottom wall of the movable piece 28 and the bottom wall of the groove. The assembly tables 27 can compress the deformable parts B29 via the movable pieces 28. A pair of mirror-fixed inserting posts A30 are fixed to the bottom wall of the assembly tables 27. The inserting posts A30 can move through the movable pieces 28. A pair of mirror-fixed inserting posts B31 are installed at the bottom of the movable pieces 28. The outer wall of the inserting post A30 has a locking opening for the inserting post B31 to engage. When the inserting post B31 engages in the locking opening, the assembly table 27 can be constrained in the groove of the rotating table 10 via the inserting post A30. The side of the inserting post B31 furthest from the inserting post A30 is fixedly connected to the movable post 32. The side of the movable post 32 furthest from the inserting post B31 is hemispherical so that the arched cover plate 25 can compress the movable post 32 to move. The outer wall of the rotating table 10 has a through opening for the movable post 32 and the inserting post B31 to move. The bottom of the movable post 32 and the through opening is fixedly connected to the deformable part C33 so that the movable post 32 can move and return to its original position.

[0047] In use, when the pair of arched cover plates 25 are opened, the inside of the arched cover plates 25 can move towards the side farther from the movable column 32. Under the deformation action of the deforming component C33, the movable column 32 pulls the interlocking column B31 out of the engagement port on the interlocking column A30, thus releasing the constraint on the interlocking column A30. Then, under the deformation action of the deforming component B29, the movable piece 28 presses the assembly table 27 to move along the groove on the rotating table 10. The assembly table 27 can then quickly pull the assembly frame 11 out of the interlocking port on the rotating table 10. The assembly rack 11 and the barrier strip 14 are removed from the rotating table 10. This allows for cleaning of the assembly rack 11 and the barrier strip 14. When a pair of arched covers 25 are closed, the walls of the arched covers 25 can press the movable column 32 to move, allowing the interlocking column B31 to engage with the interlocking column A30, thereby constraining the assembly rack 11. When the rotating table 10 rotates, the movable column 32 can move along the arched covers 25 into the outer barrel 8, maintaining pressure on the movable column 32, thus enabling rapid assembly and disassembly.

[0048] Reference Figures 4-8The barrier strip 14 is fixed to the side farther from the assembly frame 11 with a silicone strip 38. The outer wall of the silicone strip 38 is in contact with the inner wall of the slot on the rotating table 10 to ensure that the SF6 gas flows into the multiple peeling sheet 12. A U-shaped opening is reserved on the outer wall of the rotating table 10 to allow the silicone strip 38 to move, so that the barrier strip 14 and the assembly frame 11 can be removed from the rotating table 10. Several evenly arranged support columns 39 are fixed to the inside of the bending and changing strip A20. The inside of the bending and changing strip B21 is reserved with a fitting hole to allow the support column 39 to move, thereby enhancing the stability of the bending and changing strip B21. A magnet 40 is fixed to the side of the fitting column B31 farther from the changing column 32 so that the fitting column B31 and the fitting port on the fitting column A30 can quickly engage.

[0049] During the movement of the barrier strip 14, the silicone strip 38 can be pulled along the slot on the rotating table 10 to enhance the leak-proof performance between the barrier strip 14 and the rotating table 10, ensuring that SF6 gas flows through the silicone strip 38 into the multiple release sheet 12, guiding the movement of SF6 gas, and the U-shaped opening on the rotating table 10 allows the barrier strip 14 to pull the silicone strip 38 out of the rotating table 10. During the movement of the bending and changing strip B21, the interlocking hole inside can move along the support column 39 on the bending and changing strip A20 to enhance the stability of the movement of the bending and changing strip B21. When the interlocking column B31 moves, it can be attracted by the magnet 40, allowing the interlocking column B31 to quickly engage with the interlocking hole on the interlocking column A30, so that the interlocking column B31 can quickly constrain and tighten the interlocking column A30.

[0050] It should also be noted that deformable parts A22, B29 and C33 all use spiral beryllium copper wire.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
