Description

Technical Field

[0001] This invention relates to the field of waste electricity meter recycling technology, and in particular to an automated dismantling and recycling system and method for waste electricity meters. Background Technology

[0002] As a typical electronic product, electricity meters have a short lifespan and contain a significant amount of toxic substances. The green disposal of used electricity meters has attracted increasing attention, and how to achieve large-scale harmless treatment has become an urgent problem for the power industry. Improper disposal of used electricity meters will lead to a series of problems. First, it will cause electricity meters to flow back into the market, including to some underdeveloped regions domestically and internationally, causing management or market chaos. Furthermore, the reuse of used meters or the exceeding of the lifespan of smart meters will pose serious safety hazards to the power system, hindering its stable and healthy operation. Second, as waste materials, they contain various hazardous substances, leading to serious environmental pollution. Third, incomplete and inadequate information processing cannot meet the requirements of full-process control in power system management. To more environmentally friendly dispose of these used meters, they are usually disassembled, and the components are recycled and reused.

[0003] Chinese patent CN201710236448.7 discloses an automated dismantling and recycling system for used electricity meters, including a meter loading system, a dismantling and recycling system, and a first conveying mechanism for transferring used electricity meters from the loading system to the dismantling and recycling system. The dismantling and recycling system includes: a conveying component, a tray mounted on the conveying component for carrying the used electricity meters, and, sequentially arranged on the conveying component: a meter loading station, a lead seal removal and chip removal station, an outer cover loosening station, an upper cover removal station, a display screen removal station, a capacitor / battery / transformer removal station, an inner circuit board loosening station, and a lower meter recycling station. This system enables fully automated dismantling and recycling of used electricity meters, classifying and recycling various components of the meters, reducing environmental pollution, and avoiding resource waste.

[0004] However, this technical solution has certain shortcomings in use. When disassembling the circuit board and junction box inside the meter on the existing disassembly line, the capacitor is not treated. The capacitor may contain residual voltage, which can easily cause electric shock to the operator and interfere with other equipment. In addition, the capacitor may explode if it is hit during disassembly and handling. Also, the electrolyte in the capacitor is corrosive and pollutes the environment. Summary of the Invention

[0015] The dismantling line includes a stacking section, which is equipped with a stacking device and a mechanical gripper. A fork line is provided on one side of the stacking section, and an unsealing section, a dismantling section, and a processing section are provided on the fork line.

[0016] A dismantling and recycling method for an automated dismantling and recycling system for used electricity meters includes the following steps:

[0017] Step 1, Shell Disassembly Process: The stacked meter body trays are unstacked by a mechanical gripper, and the meter body is precisely positioned on the shift fork line; the shift fork line is conveyed in an assembly line, and the tray is automatically transferred to the next station. The labels on both sides of the meter body are removed by the high-hardness steel knife on the label cutting device in the unsealing section. The meter shell is disassembled by the milling device and the intelligent screw removal device.

[0018] Step 2, Loading process: The circuit board is placed on the first processing platform by the robotic arm. The voltage on the PCB panel is tested by the smart multimeter on the platform. When the voltage of the panel is within the safe range, the connection method between the junction box and the panel is detected by the industrial vision recognition device. The junction box is separated from the PCB panel through the joint cooperation of the clamping seat, the disassembly seat and the milling seat. At the same time, the capacitor on the panel can be opened and the electrolyte can be collected during the disassembly process.

[0019] Step 3, Discharge Process: When excessive residual voltage is detected on the PCB panel, the circuit board is picked up by a robotic arm and transferred to the second processing platform;

[0020] The PCB panel is fixed by the clamping seat on the platform. The position of the lifting seat is adjusted by the adjusting rail. The top plate is driven by cylinder a to descend above the capacitor on the PCB panel, so that the capacitor is in the groove at one end of the top plate. At that time, the mating plate on the positioning block will be at the capacitor lead. The two sets of mating plates are closed and contacted by the cylinders on the two sets of positioning seats. The two sets of leads are squeezed by the contact between the flexible block on the telescopic rod and the lead, so that the two sets of leads pass through the gap between the two sets of ceramic cutters and stay on the metal cutter. The insulation layer of the lead is peeled off by the squeeze, so that the lead comes into contact with the metal cutter. Thus, the capacitor can be connected to the wire 3271 to form a closed loop circuit for discharge.

[0021] Step 4, Energy Conversion Process: When the circuit is connected, the strong current in the capacitor will pass through the resistance coil in the oil storage tank. The resistance coil will convert electrical energy into heat and heat the oil in the oil storage chamber to discharge. The oil will store the heat and heat the inert gas in the first gas tank. The gas will expand when heated and be injected into the transfer tank through a pipe with an open valve on the double-port gas outlet. The piston a in the transfer tank will be fixed in position by the limiting component, thereby gradually increasing the gas pressure in the transfer tank to ensure the subsequent drilling pressure.

[0022] Step 5, Rough Grinding Process: When the gas enters the transfer tank, the airflow drives the rotating shaft a to rotate through the transmission of fan blade a and bevel gear. The rotation drives the rotating shaft b to rotate through the meshing of gear a on rotating shaft a and gear on rotating shaft b. Rotating shaft b drives gear c to rotate through the connection of belt on rotating wheel c and rotating wheel b on gear b. Gear c drives the grinding part below to rotate. The telescopic structure on the support plate ensures that the grinding part can always be in contact with the outer wall of the capacitor, thereby achieving grinding of the outer wall of the capacitor during the initial discharge, reducing the thickness of the outer wall of the capacitor, improving the efficiency of subsequent hole drilling, avoiding the explosion caused by drilling before the capacitor has discharged to a safe range, and performing the process during the initial discharge stage, thus avoiding the discharge waiting time required for drilling and improving the overall operation efficiency.

[0023] Step Six, Drilling Process: When the air pressure inside the transfer tank causes piston a to overcome the rebound resistance of multiple sets of dampers set in the card seat, that is, when the air pressure reaches the set threshold, the threshold can be set by adjusting the number of dampers. The threshold setting can extend the initial discharge time and ensure that the voltage inside the capacitor is discharged to a safe range. Piston a pushes the movable blocks on the two sets of lifting rods to move out from under the baffle and coincide with the bottom block. At that time, the lifting rod can move out of the slide groove through the retraction force, so that piston a is no longer limited and piston a can be displaced. At the same time, the lifting rod drives the grinding assembly to move upward through the support plate to open the grinding groove position.

[0024] Piston A is displaced by air pressure on the lead screw to a specified stroke until it reaches the exhaust pipe, causing the gas in the tank to be discharged. The gas enters the second gas tank for storage through the exhaust pipe and the dual-pass air inlet pipe. During the displacement process, piston A is connected to the lead screw through the nut. The movement of the nut drives the lead screw to rotate, and the lead screw further drives the drill bit on the docking shaft to rotate, thereby realizing the drilling at the grinding point. This allows the electrolyte in the capacitor to be discharged from the hole. During the drilling process, the sealing hopper is pressed against the drilled hole of the capacitor by the rebound force of multiple pressure rods, thereby preventing the electrolyte from overflowing and causing pollution.

[0025] Step 7, Electrolyte Recovery Process: When the exhaust pipe exhausts, the airflow in the exhaust tank drives the rotating shaft c to rotate through the fan blade b, and drives the rotating wheel seat to rotate through the belt on the rotating wheel a. The rotation drives the piston b to reciprocate in the recovery cylinder through the connecting rod and the traction rod. The electrolyte is drawn out from the sealed bucket through the one-way liquid extraction pipe through the pressure difference, and discharged into the collection unit for storage through the collection pipe. This realizes the collection of electrolyte and avoids the situation of electrolyte overflow in the capacitor during subsequent clamping and disassembly, which may cause pollution and corrosion.

[0026] Step 8, Reset Process: After the electrolyte is collected, the junction box is disassembled by milling. After disassembly, the finished product is transported out by a robotic arm and conveyor belt.

[0027] After closing the valves on each set of pipelines, the inert gas stored in the first gas tank has been transferred to the second gas tank after being heated and doing work. The two sets of gas tanks are moved backward by cylinder b, and the two sets of gas tanks are rotated and their positions are exchanged by the motor. Then the second gas tank is moved into the heat conduction chamber of the oil reservoir, so that the electrical energy can be collected when the capacitor discharges in the future by heating the second gas tank. The residual gas in the first gas tank can be sent to the second gas tank through the balance pipe and pump. Continuous processing can be achieved by the alternating operation of the two sets of gas tanks.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) The present invention drives two sets of interlocking plates to close and contact through the cylinders on two sets of positioning seats. The flexible block on the telescopic rod contacts and squeezes the leads to make the two sets of leads pass through the gap between the two sets of ceramic cutters and stay on the metal cutter. The insulation layer of the leads is peeled off by the squeeze, so that the leads come into contact with the metal cutter. Thus, the capacitor can be connected to the wire 3271 to form a closed loop circuit for discharge, avoiding the situation where the capacitor on the PCB panel is charged and causes an accident. At the same time, the mechanical structure of the present invention can effectively avoid losses.

[0030] (2) The present invention converts electrical energy into heat through a resistance coil and heats the oil in the oil storage chamber to discharge the energy. The heat is stored in the oil and the inert gas in the first gas tank is heated. The gas expands when heated and does work at high and low voltages through air pressure and airflow, respectively, so as to achieve grinding and drilling of the capacitor. After drilling, the electrolyte is recovered, which reduces resource consumption and usage costs, and avoids the situation where electrolyte overflows and causes pollution during disassembly and transportation due to capacitor loss.

[0031] (3) The present invention transfers gas through two sets of gas tanks and the positions of the two gas tanks can be interchanged to achieve continuous processing, thereby greatly improving the overall production efficiency of the dismantling line. Attached Figure Description

[0063] In this embodiment, when the circuit is turned on, the strong current in the capacitor will pass through the resistance coil 333 in the oil storage tank 331. The resistance coil 333 will convert electrical energy into heat and heat the oil in the oil storage chamber 332 to discharge.

The residual gas in the first gas tank 347 can be sent to the second gas tank 348 through the balance pipe 349 and the pump. Continuous processing is achieved by alternating operation of the two sets of gas tanks.

[0065] The transfer assembly 35 includes: a transfer tank 351, which is mounted on a top plate 313; an inflation pipe 352, which is connected through the transfer tank 351; an exhaust pipe 353, which is connected through the transfer tank 351; a lead screw 354, which is movably connected inside the transfer tank 351; a telescopic end 355, which is located at both ends of the lead screw 354; a piston a356, which is mounted on the lead screw 354; and a nut 357, which is mounted on the piston a356.

[0066] In this embodiment, gas is injected and concentrated in the transfer tank 351 through the gas filling pipe 352 to ensure the pressure required for subsequent drilling. The piston a356 is displaced by the gas pressure on the lead screw 354 to a specified stroke until it reaches the exhaust pipe 353, causing the gas in the tank to be discharged. The gas enters the second gas tank 348 for storage through the exhaust pipe 353 and the double-pass air inlet pipe 3492. During the displacement process, the piston a356 is connected to the lead screw 354 through the nut 357. The movement of the nut 357 drives the lead screw 354 to rotate. Furthermore, the lead screw 354 drives the drill bit 396 on the docking shaft 394 to rotate, thereby realizing drilling at the grinding point, so that the electrolyte in the capacitor can be discharged from the hole.

[0067] The air intake assembly 36 includes: an air intake tank 361, which is disposed on the air filling pipe 352; a fan blade a362, which is movably connected inside the air intake tank 361; a bevel gear 363, which is disposed inside the air intake tank 361; a rotating shaft a3631, which is connected through to the outside of the air intake tank 361; a gear a3632, which is disposed at one end of the rotating shaft a3631; a rotating shaft b364, which is disposed on the outside of the air intake tank 361; a connecting plate 3641, which is disposed on the rotating shaft b364; and a rotating wheel c3642, which is disposed at one end of the rotating shaft b364.

[0068] In this embodiment, the rotating shaft a3631 is driven to rotate by the transmission of the fan blade a362 and the bevel gear 363. The rotation is then transmitted through the meshing of the gear a3632 on the rotating shaft a3631 and the gear on the rotating shaft b364, which in turn drives the rotating shaft b364 to rotate. The rotating shaft b364 drives the gear c387 to rotate through the connection of the belt 3732 on the rotating wheel c3642 and the rotating wheel b3861 on the gear b386. The gear c387 drives the grinding part 3871 below to rotate. The telescopic structure on the support plate 385 ensures that the grinding part 3871 can always be in contact with the outer wall of the capacitor, thereby achieving grinding of the outer wall of the capacitor during the initial discharge, reducing the thickness of the outer wall of the capacitor, improving the efficiency of subsequent drilling, avoiding the explosion caused by drilling before the capacitor has discharged to a safe range, and performing the grinding during the initial discharge stage, thus avoiding the discharge waiting time required for drilling and improving the overall operation efficiency.

[0069] The exhaust assembly 37 includes: an exhaust canister 371, which is disposed on the exhaust pipe 353; a fan blade b372, which is movably connected to the exhaust canister 371; a rotating shaft c373, which is connected through to the outside of the exhaust canister 371; a rotating wheel a3731, which is disposed at one end of the rotating shaft c373; a belt 3732, which is disposed on the rotating wheel a3731; and a base plate 374, which is disposed on the rotating shaft c3731. 3. Recovery cylinder 375, which is mounted on seat plate 374; piston b3751, which is movably connected inside recovery cylinder 375; collection pipe 3752, which is connected through one end of recovery cylinder 375; traction rod 3753, which is mounted on piston b3751; wheel seat 376, which is mounted on seat plate 374; connecting rod 3761, which is mounted on wheel seat 376.

[0070] In this embodiment, the fan blade b372 drives the rotating shaft c373 to rotate, and through the connection between the belt 3732 on the rotating wheel a3731 and the rotating wheel seat 376, it drives the rotating wheel seat 376 to rotate. The rotation drives the piston b3751 to reciprocate and extend in the recovery cylinder 375 via the connecting rod 3761 and the traction rod 3753. The electrolyte in the sealed bucket 397 is extracted from the one-way liquid extraction pipe 398 through the pressure difference, and discharged into the collection unit for storage through the collection pipe 3752. This achieves the collection of electrolyte and avoids the situation where the electrolyte in the capacitor overflows during the subsequent clamping and disassembly process, causing pollution and corrosion.

[0071] The limiting component 38 includes: a retractable seat 381, with two sets of retractable seats 381 disposed on the outer wall of the transfer tank 351; a lifting rod 382, ​​with two sets of lifting rods 382 movably connected to the retractable seat 381; a bottom block 3821, disposed at the bottom end of the lifting rod 382; a movable block 3822, movably connected below the bottom block 3821; a telescopic side plate 383, disposed inside the retractable seat 381; a retaining seat 384, disposed at the bottom end of the telescopic side plate 383; and a chute 3. 841, a sliding groove 3841 is formed at the top of the card holder 384; a baffle 3842 is provided on the sliding groove 3841; a contact plate 3843 is movably connected to one side of the card holder 384; a guide groove 3844 is formed on the card holder 384; a clamping plate 3845, two sets of clamping plates 3845 are provided on the inner wall of the card holder 384; a damping 3846, multiple sets of damping 3846 are provided on the two sets of clamping plates 3845; a support plate 385 is fixedly connected to... A set of lifting rods 382; gear b386, gear b386 is located at one end of support plate 385; rotating wheel b3861, rotating wheel b3861 is located on gear b386; gear c387, gear c387 is located below gear b386; grinding part 3871, grinding part 3871 is located on gear c387; output assembly 39 includes: slide rail b391, slide rail b391 is located on top plate 313; L-shaped base plate 392, L-shaped base plate 392 is movably connected to slide rail b391; The movable sleeve 393 is mounted on the L-shaped base plate 392; the docking shaft 394 is located inside the movable sleeve 393; the fastener 395 is located inside the movable sleeve 393; the drill bit 396 is mounted on the fastener 395; the sealing hopper 397 is located at one end of the movable sleeve 393; the liquid extraction pipe 398 is connected through the sealing hopper 397; and multiple pressure rods 399 are located on the sealing hopper 397.

[0072] In this embodiment, when the air pressure inside the transfer tank 351 causes the piston a356 to overcome the rebound resistance of the multiple sets of dampers 3846 set in the card seat 384, that is, when the air pressure reaches the set threshold, the threshold can be set according to the adjustment of the number of dampers 3846. The setting of the threshold can prolong the initial discharge time and ensure that the voltage inside the capacitor is discharged to a safe range. The piston a356 pushes the movable block 3822 on the two sets of lifting rods 382 to move out from under the baffle 3842 and overlap with the bottom block 3821. At that time, the lifting rod 382 can move outward from the slide groove 3841 through the retraction force, so that the piston a356 is no longer limited and the piston a356 can be displaced. At the same time, the lifting rod 382 drives the grinding assembly to move upward through the support plate 385 to open the grinding groove position.

[0073] The drill bit 396 is easily installed using fastener 395, and is pressed into the capacitor hole by the rebound force of multiple pressure rods 399 through the sealing hopper 397 to prevent electrolyte leakage and contamination.

[0074] Example 2: Figures 1-3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0075] The dismantling line 1 includes a stacking section 11, in which a stacking device 111 and a mechanical gripper 112 are provided. A fork line 12 is provided on one side of the stacking section 11, and a desealing section 13, a dismantling section 14 and a processing section 15 are provided on the fork line 12.

[0076] In this embodiment, through a series of automated settings in the toggle line 12, unsealing section 13, disassembly section 14, and processing section 15, the electricity meter can be completely disassembled and recycled to a large extent. This is highly efficient and improves the recycling rate of resources. It is different from traditional semi-automatic or manual recycling and has good market prospects.

[0077] Example 3: Figures 1-21 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0078] A dismantling and recycling method for an automated dismantling and recycling system for used electricity meters includes the following steps:

[0079] Step 1, Shell Disassembly Process: The mechanical gripper 112 disassembles the stacked meter body trays and precisely positions the meter body onto the shift fork line 12; the shift fork line 12 is used for assembly line transport, and the tray is automatically transferred to the next station. The high-hardness steel blade on the label cutting device in the unsealing section 13 is used to cut off the labels on both sides of the meter body. The meter shell is disassembled using a milling device and a smart screw removal device.

[0080] Step 2, Loading process: The robotic arm 301 places the circuit board on the first processing platform 303. The voltage on the PCB panel 2 is tested by a smart multimeter on the platform. When the voltage of the panel is within the safe range, the connection method between the junction box 201 and the panel is detected by the industrial vision recognition device 302. The junction box 201 is separated from the PCB panel 2 through the joint cooperation of the clamping seat 3061, the disassembly seat 3062 and the milling seat 3063. At the same time, the capacitors on the panel can be opened and the electrolyte can be collected during the disassembly process.

[0081] Step 3, Discharge process: When the residual voltage of PCB panel 2 is detected to be too high, the circuit board is picked up by the robotic arm 301 and placed on the second processing platform 304.

[0082] The PCB panel 2 is fixed by the clamping seat 3061 on the platform. The position of the lifting seat 311 is adjusted by the adjusting rail 305. The top plate 313 is driven by the cylinder a312 to descend above the capacitor on the PCB panel 2, so that the capacitor is in the groove at one end of the top plate 313. At that time, the fitting plate 324 on the positioning block 323 will be at the capacitor lead. The cylinders on the two sets of positioning seats 322 drive the two sets of fitting plates 324 to close the contact. The flexible block 329 on the telescopic rod 328 contacts and squeezes the lead, so that the two sets of leads pass through the gap between the two sets of ceramic cutters 326 and stop on the metal cutter 327. The insulation layer of the lead is peeled off by the squeeze, so that the lead comes into contact with the metal cutter 327. Thus, the capacitor can be connected to the wire 3271 to form a closed loop circuit for discharge.

[0083] Step 4, Power Conversion Process: When the circuit is connected, the strong current in the capacitor will pass through the resistance coil 333 in the oil storage tank 331. The resistance coil 333 converts electrical energy into heat and heats the oil in the oil storage chamber 332 to discharge. The oil stores the heat and heats the inert gas in the first gas tank 347. The gas expands when heated and is injected into the transfer tank 351 through a pipe with an open valve on the double-port gas outlet pipe 3491. The piston a356 in the transfer tank 351 is fixed in position by the limiting component 38, thereby gradually increasing the gas pressure in the transfer tank 351 to ensure the subsequent drilling pressure.

[0084] Step 5, Rough Grinding Process: When the gas enters the transfer tank 351, the airflow drives the rotating shaft a3631 to rotate through the transmission of the fan blade a362 and the bevel gear 363. The rotation drives the rotating shaft b364 to rotate through the meshing of the gear a3632 on the rotating shaft a3631 and the gear on the rotating shaft b364. The rotating shaft b364 drives the gear c387 to rotate through the connection of the belt 3732 on the rotating wheel c3642 and the rotating wheel b3861 on the gear b386. The gear c387 drives the grinding part 3871 below to rotate. Through the telescopic structure on the support plate 385, the grinding part 3871 can always be in contact with the outer wall of the capacitor, thereby achieving grinding of the outer wall of the capacitor during the initial discharge, reducing the thickness of the outer wall of the capacitor, improving the efficiency of subsequent hole drilling, avoiding the explosion caused by drilling before the capacitor has discharged to a safe range, and performing the process during the initial discharge stage, staggering the discharge waiting time required for drilling, and improving the overall operation efficiency.

[0085] Step Six, Drilling Process: When the air pressure inside the transfer tank 351 causes the piston a356 to overcome the rebound resistance of the multiple sets of dampers 3846 set in the card seat 384, that is, the air pressure reaches the set threshold. The threshold can be set by adjusting the number of dampers 3846, and the threshold setting can extend the initial discharge time to ensure that the voltage inside the capacitor is discharged to a safe range. The piston a356 pushes the movable block 3822 on the two sets of lifting rods 382 to move out from under the baffle 3842 and overlap with the bottom block 3821. At that time, the lifting rod 382 can move outward from the slide groove 3841 through the retraction force, so that the piston a356 is no longer limited and the piston a356 can be displaced. At the same time, the lifting rod 382 drives the grinding assembly to move upward through the support plate 385 to open the grinding groove position.

[0086] The piston a356, under concentrated high pressure, moves a specified stroke on the lead screw 354 until it reaches the exhaust pipe 353, causing the gas inside the tank to be discharged. The gas then enters the second gas tank 348 for storage through the exhaust pipe 353 and the dual-pass air inlet pipe 3492. During the displacement process, the piston a356 is connected to the lead screw 354 through the nut 357. The movement of the nut 357 drives the lead screw 354 to rotate, which in turn drives the drill bit 396 on the docking shaft 394 to rotate, thereby drilling a hole at the grinding point. This allows the electrolyte inside the capacitor to be discharged from the hole. During the drilling process, the sealing hopper 397 is pressed against the drilled hole by the rebound force of multiple pressure rods 399, thus preventing electrolyte from overflowing and causing pollution.

[0087] Step 7, Electrolyte Recovery Process: When the exhaust pipe 353 exhausts, the airflow in the exhaust tank 371 drives the rotating shaft c373 to rotate via the fan blade b372, and drives the rotating shaft c373 to rotate via the belt 3732 on the rotating wheel a3731 and the rotating wheel seat 376. The rotation drives the piston b3751 to reciprocate in the recovery cylinder 375 through the connecting rod 3761 and the traction rod 3753. The electrolyte is drawn out from the sealed bucket 397 through the one-way liquid extraction pipe 398 by the pressure difference, and discharged into the collection unit for storage through the collection pipe 3752. This achieves the collection of electrolyte and avoids the situation of electrolyte overflow in the capacitor during subsequent clamping and disassembly, which may cause pollution and corrosion.

[0088] Step 8, Reset Process: After the electrolyte is collected, the junction box 201 is disassembled by milling structure. After disassembly, the finished product is transported out by robotic arm 301 and conveyor belt 307.

[0089] After the valves on each set of pipelines are closed, the inert gas stored in the first gas tank 347 is transferred to the second gas tank 348 after being heated and doing work. The two sets of gas tanks are moved backward by the cylinder b343, and the two sets of gas tanks are rotated and their positions are exchanged by the motor 345. Then the second gas tank 348 is moved into the heat conduction chamber 336 of the oil storage tank 331, so that the electrical energy can be collected when the capacitor discharges in the future by heating the second gas tank 348. The residual gas in the first gas tank 347 can be sent to the second gas tank 348 through the balance pipe 349 and the pump. Continuous processing is further achieved by the alternating operation of the two sets of gas tanks.
