Description

Technical Field

[0001] The present invention relates to the technical field of forging, and particularly to a vacuum isothermal forging hydraulic press. Background Art

[0002] In the field of modern metal processing, the vacuum isothermal forging technology has attracted much attention due to its unique advantages. This technology combines a vacuum environment and isothermal conditions, providing a more precise and efficient environment for the forging of metal materials. Against this background, the vacuum isothermal forging hydraulic press has emerged as an important device for realizing this technology. In the traditional forging process, the metal material is quickly placed in a mold for forging after heating. This process is often accompanied by uneven temperature distribution and rapid cooling, which easily leads to the generation of thermal stress and non-uniform microstructure inside the material, thus affecting the mechanical properties and surface quality of the forgings. To overcome these challenges, the vacuum isothermal forging technology was proposed. This technology heats and keeps the metal material in a vacuum environment to ensure a uniform temperature distribution during the forging process, thus effectively reducing the problems of thermal stress and non-uniform microstructure. However, to implement the vacuum isothermal forging technology, a complex equipment system is required to support it. Among them, the vacuum isothermal forging hydraulic press, as one of the key devices, plays a crucial role. This hydraulic press not only needs to have the ability to work stably in a vacuum environment but also needs to be able to apply precise and stable pressure to the metal material under isothermal conditions to achieve high-quality forging.

[0003] For example, in the patent document with the prior art publication number CN220760912U, this patent document belongs to the technical field of hydraulic forging machines, and particularly to a forging hydraulic press, which includes a processing table, a fixed frame, a top plate, a hammer forging block, and a hydraulic cylinder, and also includes a placement disk, a first servo motor, and a clamping mechanism. The clamping mechanism includes a moving seat, an electric push rod, a lifting vertical plate, a second servo motor, a transfer plate, a mounting rod, and a clamping plate; the moving seat is slidably mounted on the processing table, the electric push rod is mounted on the moving seat, and the lifting vertical plate is fixed to the top end of the piston rod of the electric push rod; in the forging hydraulic press of the present invention, by providing two sets of clamping mechanisms, the workpiece can be firmly clamped to ensure the stability of the workpiece. By starting the first servo motor to drive the placement disk to rotate, the workpiece can be driven to rotate in the horizontal plane. By starting the second servo motor to drive the transfer plate to rotate, the workpiece can be driven to rotate in the vertical plane to adjust the hammer forging position of the workpiece to meet different processing needs, and the adjustment is convenient without manual adjustment.

[0004] The above-mentioned prior art can clamp the workpiece by setting two sets of clamping mechanisms to ensure the stability of the workpiece. However, in actual use, the workpiece often releases harmful gases during the high-temperature forging process. If these gases are directly discharged into the atmosphere without treatment, they will cause significant pollution to the environment and affect the air quality and ecological balance. Specifically, the high temperature generated during the forging process not only causes the workpiece to deform, but also promotes the volatilization of harmful substances inside the material. These harmful substances include but are not limited to heavy metal vapors, harmful gases and tiny particles. Once released into the air, they will not only cause long-term pollution to the atmospheric environment, but may also pose a threat to human health through the respiratory system and skin contact. To this end, the present application proposes a vacuum isothermal forging hydraulic press. Summary of the invention

One end of the activated carbon plate is fixedly connected with a plurality of connecting rods, and one ends of the plurality of connecting rods extend into the extension plates and are fixedly connected with pistons.

[0012] Preferably, a bracket is fixedly connected inside the air filter housing.

One end of the first spring rod away from its telescopic end is rotatably connected with a plurality of blades, and a ball in contact with the seesaw is rotatably connected to one side of each of the plurality of blades.

[0013] Preferably, the liquid discharge assembly includes a pull handle rotatably connected to the bottom of the auxiliary rod.

[0018] Preferably, a gasket is arranged at one end of the seesaw, and the gasket is adapted to the drain port inside the coolant tank.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The air in the vacuum chamber is quickly evacuated through the vacuum pump, vacuum nozzle and air groove to avoid material oxidation at high temperature and improve the purity and mechanical properties of forgings. The three-way valve flexibly switches the air pipe, air pipe and exhaust pipe to achieve rapid establishment and release of the vacuum environment and shorten the production cycle. The movable plate is closely matched with the vacuum chamber through the sealing groove to ensure the airtightness of the forging process and prevent external air from infiltrating. The first hydraulic rod drives the movable plate to rise and fall to achieve rapid opening and closing of the vacuum chamber, which is convenient for material loading and unloading. The second hydraulic rod drives the pressure block to apply uniform pressure to the material. Combined with isothermal heating (heater) under vacuum environment, precise control of material plastic flow is achieved to reduce internal defects. The matching design of the pressure block and the mold ensures the dimensional accuracy and surface finish of the forging.

[0021] 2. The filter can intercept large particles of impurities in the gas, and the activated carbon plate further absorbs fine pollutants and harmful gases in the gas, thereby ensuring that the exhaust gas in the vacuum chamber is filtered to meet the emission standards. The clever combination of the power components (seesaw, crank, slider, push rod) and the scraper realizes the automatic cleaning of the filter. As the gas flows, the blades rotate, and then the seesaw is touched by the ball. This series of chain reactions causes the filter and the scraper to produce misaligned friction, effectively removing impurities on the filter. The design of the piston and the cleaning liquid chamber further enhances the cleaning effect. When the activated carbon plate moves, the piston is driven to slide in the extension plate through the connecting rod to release the cleaning liquid. These cleaning liquids are sprayed on the filter through the drain nozzle, which helps to dissolve and flush out stubborn impurities. The setting of the coil not only provides a flow path for the gas, but also cleverly utilizes the excess heat generated during the forging process. This heat is absorbed by the water in the heating water tank, realizing the recovery and utilization of waste heat, which helps to reduce energy consumption and improve energy efficiency. The cooperation between the first spring rod, blades, balls and seesaw not only drives the cleaning process of the filter, but also forms the first barrier to prevent coolant leakage through the movement of the seesaw and the gasket and the drain port in the coolant tank. The cooperation between the liquid blocking ring and the movement of the seesaw further ensures the safety of the coolant in the coolant tank. The flexible switching of the three-way valve enables the system to quickly switch between different working stages, such as emptying, filtering, purification, etc., ensuring the continuity and efficiency of the entire forging process. The continuous suction of the vacuum pump not only maintains the vacuum environment of the vacuum chamber, but also drives the circulation of the gas, providing power for waste heat recovery and gas purification.

[0022] 3. The cold water stored in the water tank can effectively absorb the waste heat of the gas flowing through the coil pipe, thereby reducing the temperature of the gas. This design not only improves the efficiency of gas cooling, but also helps to extend the service life of the materials in the vacuum chamber, because the lower temperature can reduce the thermal stress of the materials. The gas filter shell is not only used to filter the gas, but also serves as a channel for the coolant to enter the gas path. When the gas temperature is high, through the action of the liquid discharge assembly, the coolant in the coolant tank can be flexibly discharged into the gas filter shell to further cool the gas. The ingenious cooperation between the liquid blocking ring and the liquid discharge assembly realizes the on-demand discharge of the coolant. When the gas temperature reaches a certain level, the liquid blocking ring moves to open the drain port, allowing the coolant to flow out. This design ensures that the coolant is only used when necessary, avoiding waste. The liquid discharge assembly composed of auxiliary rods, pull handles, sliding rods, etc. can automatically adjust the discharge of the coolant according to the change of the water temperature in the water tank. When the water temperature rises and the air pressure increases, the piston piece is pushed upward, and then drives the sliding rod to move through the auxiliary rod and the pull handle. Finally, the liquid blocking ring is misaligned to open the drain port. The design of the second spring rod and the piston piece not only realizes the monitoring of the air pressure in the water tank, but also provides power for the liquid discharge assembly through its reciprocating motion. This design simplifies the structure of the system and improves the reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 4, the present invention provides a technical solution: a vacuum isothermal forging hydraulic press, including a frame 100 and a vacuum chamber 102 opened inside it. A mold 103 is arranged inside the vacuum chamber 102. An active plate 101 adapted to the vacuum chamber 102 is arranged inside the frame 100. A fuel tank 105 is fixedly connected to the top of the frame 100. A first hydraulic rod 104 for driving the movement of the active plate 101 is fixedly connected inside the frame 100. A pressing block 108 is arranged inside the active plate 101. A second hydraulic rod 106 for driving the movement of the pressing block 108 is fixedly connected inside the frame 100. A sealing groove 109 is opened at the bottom of the active plate 101. A plurality of heaters 107 are fixedly connected inside the vacuum chamber 102. By setting the cooperation of the active plate 101 and the vacuum chamber 102, it is convenient to seal the vacuum chamber 102 and at the same time convenient for storing and accessing materials. The first hydraulic rod 104 can be set to push the active plate 101 downward, and the second hydraulic rod 106 can drive the pressing block 108 to move.

[0040] Please refer to Figure 3 , Figure 4 and Figure 8 , further including a vacuum nozzle 200, arranged inside the active plate 101 for evacuating the gas inside the vacuum chamber 102. A vacuum pump 202 is fixedly connected to one side of the active plate 101. The input end of the vacuum pump 202 is communicated with a coil pipe 208. An air groove 201 for communicating the coil pipe 208 and the vacuum nozzle 200 is opened inside the active plate 101. The output end of the vacuum pump 202 is fixedly connected to an air pipe 203. A telescopic pipe 204 is fixedly connected inside the air pipe 203. A connecting air pipe 205 communicated with the air pipe 203 is communicated with one side of the vacuum chamber 102. A three-way valve 206 is fixedly connected to the outer surface of the connecting air pipe 205. An exhaust pipe 207 is communicated with one side of the three-way valve 206. By setting the cooperation of the vacuum nozzle 200 and the vacuum pump 202, the air inside the vacuum chamber 102 can be evacuated to create a vacuum environment for it. The connecting air pipe 205 can be set to facilitate the entry of external gas into the vacuum chamber 102 to break the vacuum environment and facilitate the opening of the active plate 101. The three-way valve 206 can flexibly switch the communication relationship between the connecting air pipe 205, the air pipe 203 and the exhaust pipe 207, so as to flexibly adapt to different use environments.

[0041] Specifically, when in use, first place the material inside the mold 103, and then drive the first hydraulic rod 104 to make the active plate 101 move downward to cover the top of the vacuum chamber 102 to make it a sealed space. Then turn on the vacuum pump 202 to suck air inside the coil pipe 208 so that a plurality of vacuum nozzles 200 generate suction. At this time, operate the three-way valve 206 to block the connecting air pipe 205 so that the vacuum chamber 102 gradually becomes a vacuum environment. Then turn on the heater 107 to heat the material. When it reaches the plastic state, then operate the second hydraulic rod 106 to push the pressing block 108 to move and generate a strong pressure to forge the material.

[0042] In summary, the air in the vacuum chamber 102 is quickly evacuated through the vacuum pump 202, the vacuum nozzle 200 and the air groove 201 to avoid oxidation of the material under high temperature and improve the purity and mechanical properties of the forgings. The three-way valve 206 flexibly switches the air pipe 205, the air pipe 203 and the exhaust pipe 207 to achieve rapid establishment and release of the vacuum environment and shorten the production cycle. The movable plate 101 is closely matched with the vacuum chamber 102 through the sealing groove 109 to ensure the airtightness of the forging process and prevent external air from infiltrating. The first hydraulic rod 104 drives the movable plate 101 to rise and fall to achieve rapid opening and closing of the vacuum chamber 102, which is convenient for material loading and unloading. The second hydraulic rod 106 drives the pressing block 108 to apply uniform pressure to the material. Combined with the isothermal heating heater 107 under the vacuum environment, precise control of the plastic flow of the material is achieved to reduce internal defects. The matching design of the pressing block 108 and the mold 103 ensures the dimensional accuracy and surface finish of the forgings.

[0043] Example 2: Please refer to Figure 9 , Figure 10 as well as Figure 11 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a vacuum isothermal forging hydraulic press, further comprising an air filter housing 300, which is fixedly connected to the inside of the coil 208, and is provided with a filter screen 301 inside, one end of the filter screen 301 is fixedly connected to an activated carbon plate 302, a plurality of scrapers 314 that can contact the filter screen 301 are provided inside the air filter housing 300, and a power component that drives the filter screen 301 and the plurality of scrapers 314 to be misaligned is provided inside the air filter housing 300, and the impurities in the gas can be effectively removed by setting the cooperation of the filter screen 301 and the activated carbon plate 302, thereby meeting the emptying requirements, the filter screen 301 can intercept large particles of impurities in the gas, and the activated carbon plate 302 can intercept pollutants in the gas, wherein the power component and the scraper 314 cooperate with each other to synchronously clean the impurities in the filter screen 301, and at the same time, the filtered gas can continue to flow back into the vacuum chamber 102 to continue to carry impurities and exhaust gas for filtering, thereby purifying the harmful gas that may be generated by the volatilization of materials at high temperature in the vacuum chamber 102.

[0044] Further, the power assembly includes a plurality of seesaws 308 rotatably connected to the inner wall of the air filter housing 300, and one end of each of the plurality of seesaws 308 is connected to a crank 309 by a ball. A plurality of sliding bars 310 are slidably connected to the inner wall of the air filter housing 300, and one end of each of the plurality of cranks 309 is rotatably connected to one of the plurality of sliding bars 310. One end of each of the plurality of sliding bars 310 is fixedly connected to a push rod 311 that abuts against the activated carbon plate 302. A plurality of extension plates 312 for supporting the scraper 314 are fixedly connected to the inside of the air filter housing 300, and empty slots are formed in the extension plates 312. Drain nozzles 313 communicating with the empty slots are formed at the bottoms of the extension plates 312. A cleaning liquid chamber 303 is fixedly connected to the outer surface of the air filter housing 300. The empty slots in the extension plates 312 communicate with the inside of the cleaning liquid chamber 303. One end of the activated carbon plate 302 is fixedly connected to a plurality of connecting rods 316, and one end of each of the plurality of connecting rods 316 extends into the extension plates 312 and is fixedly connected to a piston 315. By providing the seesaw 308 that can abut against the ball 307 to drive the movement of the filter screen 301, so that it is misaligned with the scraper 314 to generate frictional force, and by providing the cooperation between the piston 315 and the extension plate 312, the cleaning liquid in the cleaning liquid chamber 303 can be discharged following the movement of the activated carbon plate 302, thereby improving the cleaning effect on the filter screen 301.

[0045] Among them, please refer to Figure 11 , Figure 12 and Figure 13 , a bracket 304 is fixedly connected to the inside of the air filter housing 300. A first spring rod 305 with a telescopic end fixedly connected to the activated carbon plate 302 is fixedly connected to the inside of the bracket 304. A plurality of blades 306 are rotatably connected to the end of the first spring rod 305 away from its telescopic end. A ball 307 that abuts against the seesaw 308 is rotatably connected to one side of each of the plurality of blades 306. A gasket is provided at one end of the seesaw 308, and the gasket is adapted to the drain port in the coolant tank 405. When the seesaw 308 is moved by the abutment of the ball 307, the drain port of the coolant tank 405 will be opened, which cooperates with the subsequent movement of the liquid blocking ring 406 to form a double block to protect the leakage of the coolant in the coolant tank 405.

[0046] Specifically, after plasticity is completed, there will be excess heat in the vacuum chamber 102. At this time, operate the three-way valve 206 to connect the connecting air pipe 205 with the exhaust pipe 207 to allow external air to enter the interior of the vacuum chamber 102. Then, operate the three-way valve 206 again to connect the connecting air pipe 205 with the air pipe 203, and at the same time, turn on the vacuum pump 202 so that the vacuum nozzle 200 continuously sucks air, and the air discharged through the air pipe 203 enters the interior of the connecting air pipe 205, thereby forming a circulating gas. When the gas passes through the coil pipe 208, it will heat the water in the heating water tank 400 and release heat, forming waste heat recovery. At the same time, the gas in the coil pipe 208 will enter the interior of the vacuum pump 202 through the filter gas housing 300. When the gas passes through the filter gas housing 300, it will first be filtered by the filter screen 301 to intercept the particles and debris carried inside, and the activated carbon plate 302 will refine and filter the gas to adsorb the impurities inside. When the gas continuously passes through the filter gas housing 300, it will drive the blade 306 to rotate, thereby driving the ball 307 to continuously contact the seesaw 308, causing one end of it to be pried up, thus pushing one end of the crank 309 to move, and further driving the slide bar 310 to drive the push rod 311 to push the activated carbon plate 302 to move, so that the connecting rod 316 drives the piston 315 to slide inside the extension plate 312, thereby pushing the cleaning liquid in the cleaning liquid chamber 303 to flow out through the plurality of liquid discharge nozzles 313. At the same time, when the activated carbon plate 302 moves, it will drive the filter screen 301 to be misaligned with the plurality of scraping plates 314, thereby generating friction, thus realizing cleaning.

[0047] In summary, the filter screen 301 can intercept large particulate impurities in the gas, and the activated carbon plate 302 further adsorbs fine pollutants and harmful gases in the gas, thereby ensuring the filtration of the waste gas in the vacuum chamber 102, so as to meet the emission standards. The ingenious cooperation of the power component seesaw 308, crank 309, slide bar 310, push rod 311 and scraper 314 realizes the automatic cleaning of the filter screen 301. As the gas flows, it drives the blade 306 to rotate, and then touches the seesaw 308 through the ball 307. This series of chain reactions causes the filter screen 301 and the scraper 314 to have misaligned friction, effectively removing the impurities on the filter screen 301. The design of the piston 315 and the cleaning liquid chamber 303 further enhances the cleaning effect. When the activated carbon plate 302 moves, it drives the piston 315 to slide in the extension plate 312 through the connecting rod 316, releasing the cleaning liquid. These cleaning liquids are sprayed on the filter screen 301 through the liquid discharge nozzle 313, which helps to dissolve and wash away stubborn impurities. The setting of the coil pipe 208 not only provides a flow path for the gas, but also cleverly utilizes the excess heat generated during the forging process. This heat is absorbed by the water in the heating water tank 400, realizing the recovery and utilization of waste heat, which helps to reduce energy consumption and improve energy utilization efficiency. The mutual cooperation of the first spring rod 305, blade 306, ball 307 and seesaw 308 not only drives the cleaning process of the filter screen 301, but also forms the first barrier to prevent the coolant from leaking through the movement of the seesaw 308 and its adaptation to the gasket and the drain port in the coolant tank 405. The cooperation of the liquid blocking ring 406 and the movement of the seesaw 308 further ensures the safety of the coolant in the coolant tank 405. The flexible switching of the three-way valve 206 enables the system to quickly switch between different working stages, such as evacuation, filtration, purification, etc., ensuring the continuity and high efficiency of the entire forging process. The continuous suction of the vacuum pump 202 not only maintains the vacuum environment of the vacuum chamber 102, but also drives the circulation of the gas, providing power for waste heat recovery and gas purification.

[0048] Embodiment 3: Please refer to Figure 6 , Figure 7 and Figure 14, the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1: A vacuum isothermal forging hydraulic press further includes a water tank 400, which is opened inside the movable plate 101 and used for storing cold water.

A plurality of drain ports communicating with the air filter housing 300 are opened inside the coolant tank 405, and a liquid blocking ring 406 is arranged inside the coolant tank 405. An auxiliary rod 404 is arranged inside the exhaust groove 401. A liquid discharging assembly for driving the liquid blocking ring 406 to move is arranged at the bottom of the auxiliary rod 404. By setting the liquid discharging assembly, flexible liquid discharging can be carried out according to the temperature of the gas in the air filter housing 300, so as to cool the gas, thereby improving the heat dissipation effect of the subsequent vacuum chamber 102.

[0049] Among them, the liquid discharging assembly includes a pull handle 407 rotatably connected to the bottom of the auxiliary rod 404. A slide rod 408 fixedly connected to the liquid blocking ring 406 is slidably connected inside the coolant tank 405. One end of the pull handle 407 away from the auxiliary rod 404 is rotatably connected to the slide rod 408. A plurality of third spring rods 409 are fixedly connected inside the coolant tank 405, and the plurality of third spring rods 409 are all adapted to the plurality of drain ports.

[0050] Furthermore, a second spring rod 402 is fixedly connected inside the exhaust groove 401. A piston piece 403 is fixedly connected to the telescopic end of the second spring rod 402. The top of the auxiliary rod 404 is fixedly connected to the piston piece 403. As the water in the water tank 400 warms up, high pressure will be generated and the piston piece 403 will be pushed upward, so that it crosses the exhaust groove 401 and discharges steam. In this way, the reciprocating drive of the piston piece 403 can be realized, and it can be known from this that the water temperature in the water tank 400 is too high to effectively absorb the waste heat of the gas in the coil 208.

[0051] Specifically, as the temperature of the water in the water tank 400 increases, it will be difficult for the internal heat of the gas in the air filter housing 300 to be absorbed. The air pressure in the water tank 400 will also increase and push the piston piece 403 upward to squeeze the second spring rod 402, so that the piston piece 403 drives the auxiliary rod 404 to move upward indirectly and pulls the pull handle 407 to tilt, thereby driving the slide rod 408 to move, so that the liquid blocking ring 406 is displaced and the drain port in the coolant tank 405 is opened, so that the third spring rod 409 squeezes the coolant in the coolant tank 405 and discharges it into the gas in the air filter housing 300 for cooling.

[0052] In summary, the cold water stored in the water tank 400 can effectively absorb the waste heat of the gas flowing through the coil pipe 208, thereby reducing the temperature of the gas. This design not only improves the efficiency of gas cooling, but also helps to extend the service life of the materials in the vacuum chamber 102, because the lower temperature can reduce the thermal stress of the materials. The gas filter shell 300 is not only used to filter the gas, but also serves as a channel for the coolant to enter the gas path. When the gas temperature is high, through the action of the liquid discharge assembly, the coolant in the coolant tank 405 can be flexibly discharged into the gas filter shell 300 to further cool the gas. The ingenious cooperation between the liquid blocking ring 406 and the liquid discharge assembly realizes the on-demand discharge of the coolant. When the gas temperature reaches a certain level, the liquid blocking ring 406 moves to open the drain port to allow the coolant to flow out. This design ensures that the coolant is only used when necessary, avoiding waste. The liquid discharge assembly composed of the auxiliary rod 404, the pull handle 407, the sliding rod 408, etc. can automatically adjust the discharge of the coolant according to the change of the water temperature in the water tank 400. When the water temperature rises and the air pressure increases, the piston piece 403 is pushed upward, and then drives the sliding rod 408 to move through the auxiliary rod 404 and the pull handle 407, and finally makes the liquid blocking ring 406 shift to open the drain port. The design of the second spring rod 402 and the piston piece 403 not only realizes the monitoring of the air pressure in the water tank 400, but also provides power for the liquid discharge assembly through its reciprocating motion. This design simplifies the structure of the system and improves the reliability of the system.

[0053] Working principle: During use, first place the material inside the mold 103, and then drive the first hydraulic rod 104 to lower the movable plate 101 to cover the top of the vacuum chamber 102 to make it a sealed space. Then turn on the vacuum pump 202 to suck air from inside the coil pipe 208, so that the multiple vacuum nozzles 200 generate suction. At this time, operate the three-way valve 206 to block the connecting air pipe 205, so that the vacuum chamber 102 gradually becomes a vacuum environment. Then turn on the heater 107 to heat the material. When it reaches the plastic state, then operate the second hydraulic rod 106 to push the pressing block 108 to move to generate a strong pressure to forge the material;

[0054] After plasticity is completed, there will be excess heat in the vacuum chamber 102. At this time, operate the three-way valve 206 to connect the connecting pipe 205 with the evacuation pipe 207 to allow external air to enter the interior of the vacuum chamber 102. Then, operate the three-way valve 206 again to connect the connecting pipe 205 with the air pipe 203, and at the same time turn on the vacuum pump 202 so that the vacuum nozzle 200 continuously sucks air, and the air discharged through the air pipe 203 enters the interior of the connecting pipe 205, thus forming a circulating gas. When the gas passes through the coil pipe 208, it will heat the water in the heating water tank 400 and release heat, forming waste heat recovery. At the same time, the gas in the coil pipe 208 will enter the interior of the vacuum pump 202 through the filter gas housing 300. When the gas passes through the filter gas housing 300, it will first be filtered by the filter screen 301 to intercept the particles and debris carried inside, and the activated carbon plate 302 will refine and filter the gas to adsorb the impurities inside. When the gas continuously passes through the filter gas housing 300, it will drive the blade 306 to rotate, thereby driving the ball 307 to continuously touch the seesaw 308, causing one end of it to be pried up, thus pushing one end of the crank 309 to move, and then driving the slide bar 310 to drive the push rod 311 to push the activated carbon plate 302 to move, so that the connecting rod 316 drives the piston 315 to slide inside the extension plate 312, thereby pushing the cleaning liquid in the cleaning liquid chamber 303 to flow out through multiple liquid discharge nozzles 313. At the same time, when the activated carbon plate 302 moves, it will drive the filter screen 301 to be misaligned with multiple scraping plates 314, thereby generating friction, thus realizing cleaning;

[0055] As the temperature of the water in the water tank 400 increases, it will be difficult for the heat inside the gas passing through the filter gas housing 300 to be absorbed. The air pressure in the water tank 400 will also increase, pushing the piston piece 403 to move upward and squeeze the second spring rod 402, so that the piston piece 403 drives the auxiliary rod 404 to move upward intermittently and pull the pull handle 407 to tilt, thereby driving the slide rod 408 to move, causing the liquid blocking ring 406 to be misaligned and opening the drain port in the coolant tank 405, so that the third spring rod 409 squeezes the coolant in the coolant tank 405 to be discharged into the gas in the filter gas housing 300 for cooling.
