[0003] The patent with the application number 202123162888.3 discloses an exhaust device for the replacement chamber of an atmosphere roller hearth furnace, belonging to the technical field of lithium battery material equipment, including a roller hearth furnace, an exhaust device is provided on the roller hearth furnace, the exhaust device includes a water-cooling component, a drying component and a filtering component, the exhaust port on the roller hearth furnace is connected to the air inlet of the water-cooling component through a water-cooling pipe, the exhaust port of the water-cooling component is connected to the air inlet of the drying component through a drying pipe, and the exhaust port of the drying component is connected to the filtering component through a filtering pipe; the water-cooling component includes a water-cooling box and a water-cooling pipe arranged in the water-cooling box; the drying component includes a dryer, and an adsorption layer, a buffer baffle and a drying layer are sequentially arranged in the dryer from top to bottom; the filtering component includes a filter, and a plurality of filtering areas are arranged in the filter; this patent is convenient to operate and has strong practicability, effectively solving the problem that a large amount of water vapor remains in the inlet replacement chamber during the use of the existing atmosphere roller hearth furnace, affecting the processing stability of materials, but there is still a little condensed water in the replacement chamber of this device, so there is still a risk of condensed water droplets falling on the product surface. At the same time, the replacement chamber discharges naturally during ventilation, and the ventilation efficiency is low, affecting the overall working efficiency. Therefore, it is very necessary to design an exhaust device for the replacement chamber of an atmosphere roller hearth furnace with strong practicability, which can prevent water vapor from condensing and dripping on the material and improve the gas replacement efficiency in the replacement chamber. Summary of the Invention

[0004] The purpose of the present invention is to provide an exhaust device for the replacement chamber of an atmosphere roller hearth furnace to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: An exhaust device for a replacement chamber of an atmosphere roller hearth furnace, comprising a transfer table, and further comprising a processing device and a replacement device; the processing device includes a base, a guide plate, a replacement chamber body, a calcination furnace and an exhaust pipe, the base is fixedly connected to the bottom of the transfer table, the guide plate is fixedly connected to the inner wall of the base, the replacement chamber body is fixedly connected to the top of the transfer table, the calcination furnace is fixedly connected to the top of the transfer table, and the exhaust pipe is communicated with the top of the calcination furnace; the replacement device includes a suction and exhaust filter, an intake pipe, an outlet pipe and a baffle, the suction and exhaust filter is fixedly connected to the top of the calcination furnace, the intake pipe is communicated with the left side of the suction and exhaust filter, the outlet pipe is communicated with the top of the suction and exhaust filter, and the baffle is fixedly connected to the inner walls of the replacement chamber body and the calcination furnace. The water vapor in the replacement chamber body will condense on the top wall inside the replacement chamber body, and the water droplets will be guided to both sides through the inclined surface on the top wall to prevent the water droplets from dripping directly after condensation. When the water droplets flow and drip to both sides, they will fall on the baffle and slide down from both sides of the replacement chamber body to the base under the guidance of the baffle, so as to effectively prevent the condensed water droplets in the replacement chamber from falling on the surface of the material. At the same time, when the replacement chamber body is ventilated, the suction and exhaust filter will start and extract the gas in the replacement chamber body into the exhaust pipe and discharge it together. The suction and exhaust filter has a frequency conversion function, which can adjust the size of the suction and exhaust air volume, control the suction and exhaust pressure of the replacement chamber, and will not affect the density of the product. Through the suction and exhaust function of the suction and exhaust filter, the replacement efficiency of the air in the replacement chamber is improved; the right side of the replacement chamber body is in contact with the left side of the calcination furnace, one end of the intake pipe away from the suction and exhaust filter is communicated with the top of the replacement chamber body, and one end of the outlet pipe away from the suction and exhaust filter is communicated with the surface of the exhaust pipe.

[0006] According to the above technical solution, recovery devices are arranged on the front and rear sides of the extraction filter. The recovery device includes a water suction pipe, a mounting box, an impeller, a turntable, a pulling rope, an inclined block and a limiting plate. The water suction pipe is communicated with the front and rear sides of the extraction filter. The mounting box is communicated with the lower surface of the water suction pipe. The impeller is rotatably connected to the inner wall of the mounting box. The turntable is fixedly connected to the axles on both sides of the impeller through connecting rods. The pulling rope is wound around the surface of the turntable. The inclined block is fixedly connected to the end of the pulling rope away from the turntable. The limiting plate is slidably connected to the inner wall of the water suction pipe. The condensed water droplets in the replacement chamber and the calcination furnace will eventually fall into the base under the guidance of the baffle and be collected. Each time the extraction filter is started, the accumulated water in the base will be pumped out together through the water suction pipe. When the water flow moves to the impeller, the water flow will push the impeller to rotate. The impeller will drive the turntable to rotate. The turntable will drive the pulling rope to wind around its own surface. The pulling rope will pull the inclined block to move. The limiting plate above the inclined block will move downward along the inclined surface of the inclined block, so that the through holes on the limiting plate move out of the water suction pipe, and the water suction pipe will no longer be driven by the extraction filter to pump water. At this time, the water flow will flow out through the mounting box, so that the water collected in the base can be pumped out while replacing the air, preventing the water from accumulating and then contacting the transfer table, and indirectly contacting the discharged material, affecting the production quality. The bottom of the limiting plate is in contact with the top of the inclined block. A plurality of through holes are formed on the surface of the limiting plate, and the limiting plate is located on the side of the impeller close to the extraction filter. The end of the water suction pipe away from the extraction filter is communicated with the front and rear sides of the base.

[0007] According to the above technical solution, a cooling device is provided on the inner wall of the exhaust filter. The cooling device includes a filter plate, a knocking block, a moving rod, a pushing block, a spiral pipe, a pipe and a collecting plate. The filter plate is installed on the inner wall of the exhaust filter. The knocking block is fixedly connected to the top of the filter plate. The moving rod is slidably connected to the inner wall of the exhaust filter. The pushing block is fixedly connected to the side of the limiting plate close to the exhaust filter. The spiral pipe is wound around the surface of the exhaust pipe. The pipe is communicated with the surface of the spiral pipe. The collecting plate is fixedly connected to the top of the calciner. When gas replacement is carried out, the filter plate in the exhaust filter filters the replaced air, so that impurities adhere to the filter plate. When the limiting plate moves downward, it drives the pushing block to move downward. The pushing block pushes the moving rod to move through an inclined surface. The moving rod moves and impacts the knocking block, so that the knocking block drives the filter plate to vibrate. The vibration can prompt the impurities on the surface of the filter plate to spread out, prevent the impurities from accumulating on the filter plate, and thus cause blockage of the filter plate, improve the collection and filtration amount of impurities. At the same time, the water discharged from the water suction pipe falls into the collecting plate, and the water pump outside the workshop pumps the water in the collecting plate out of the workshop through the spiral pipe and the pipe for discharge. At the same time, the water in the spiral pipe can cool the exhaust pipe by water cooling, improve the cooling efficiency and reduce heat emission; One end of the moving rod away from the exhaust filter contacts the side of the pushing block away from the limiting plate, and inclined surfaces are provided on both the end of the moving rod away from the exhaust filter and the side of the pushing block away from the limiting plate.

[0008] According to the above technical solution, a separating device is provided on the top of the guiding plate. The separating device includes an elastic rod, a scraping plate, an elastic plate and a filter screen. The elastic rod is fixedly connected to the top of the guiding plate. The scraping plate is fixedly connected to the end of the elastic rod away from the guiding plate. The elastic plates are fixedly connected to the front and back sides of the scraping plate. The filter screen is installed on the inner wall of the base. When the conveying table operates, its roller rotates to drive the product to move. At the same time, the rotation of the roller pushes the scraping plate in contact with it to move. The moved scraping plate will reset again under the elastic action of the elastic rod, so that the scraping plate contacts the surface of the roller reciprocally, and thus the impurities and moisture on the surface of the roller can be scraped off, preventing the moisture and impurities from affecting the placement of the next material. At the same time, the filter screen can filter the impurities in the condensed water to prevent the impurities from entering the water suction pipe and causing blockage. When the scraping plate moves, it drives the elastic plate to move together, and the elastic plate pushes the impurities blocked on the surface of the filter screen to displace, preventing the impurities from blocking at the filter screen and thus affecting the water absorption effect of the water suction pipe; The side of the scraping plate away from the elastic rod contacts the surface of the roller in the conveying table, and the side of the elastic plate away from the scraping plate contacts the side of the filter screen away from the base.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] In the present invention, through the coordinated operation among the transfer table, the base, the guide plate, the replacement chamber body, the calcination furnace, the exhaust pipe, the exhaust filter, the intake pipe, the outlet pipe, and the baffle, the water droplets are guided to both sides by the inclined surface on the top wall, preventing the water droplets from directly dripping after condensation. When the water droplets flow and drip to both sides, they will fall on the baffle and slide down from both sides of the replacement chamber body to the base under the guidance of the baffle, thus effectively preventing the condensed water droplets in the replacement chamber from falling on the surface of the material. At the same time, the exhaust filter will extract the gas in the replacement chamber body into the exhaust pipe and discharge it together. The exhaust filter has a variable frequency function, which can adjust the size of the exhaust air volume, control the exhaust pressure of the replacement chamber, and will not affect the density of the product. Through the exhaust function of the exhaust filter, the air replacement efficiency in the replacement chamber is improved.

[0011] In the present invention, through the coordinated operation among the water suction pipe, the installation box, the impeller, the turntable, the pull rope, the inclined block, and the limiting plate, the water collected in the base can be extracted while replacing the air, preventing the water from accumulating and then contacting the transfer table, and indirectly contacting the discharged material, thus affecting the production quality.

[0012] In the present invention, through the coordinated operation among the filter plate, the knocking block, the moving rod, the pushing block, the spiral pipe, the pipeline, and the collecting plate, the knocking block drives the filter plate to vibrate. The vibration can cause the impurities on the surface of the filter plate to spread out, preventing the impurities from accumulating on the filter plate and causing blockage of the filter plate, improving the collection and filtration amount of impurities. At the same time, the water discharged from the water suction pipe will fall into the collecting plate, and the water pump outside the factory building will extract the water in the collecting plate through the spiral pipe and the pipeline and discharge it outside the factory building. At the same time, the water in the spiral pipe can cool the exhaust pipe by water cooling, improving the cooling efficiency and reducing the heat emission.

[0013] In the present invention, through the coordinated operation among the elastic rod, the scraper, the elastic plate, and the filter screen, the scraper reciprocally contacts the surface of the roller shaft, thereby scraping the impurities and moisture on the surface of the roller shaft, preventing the moisture and impurities from affecting the placement of the next material. At the same time, the filter screen can filter the impurities in the condensed water, preventing the impurities from entering the water suction pipe and causing blockage. When the scraper moves, it will drive the elastic plate to move together, and the elastic plate will push the impurities blocked on the surface of the filter screen to displace, preventing the impurities from blocking at the filter screen and affecting the water absorption effect of the water suction pipe.

The water vapor in the replacement chamber body 4 will condense on the top wall inside the replacement chamber body 4, and the water droplets will be guided to both sides through the inclined surface on the top wall to prevent the water droplets from dripping directly after condensation. When the water droplets flow and drip to both sides, they will fall on the baffle 13 and slide down from both sides of the replacement chamber body 4 to the base 2 under the guidance of the baffle 13. Thus, it can effectively prevent the condensed water droplets in the replacement chamber from falling on the surface of the material.

The limiting plate 77 is slidably connected to the inner wall of the water suction pipe 71. The condensed water droplets in the replacement chamber and the calcining furnace 5 will eventually fall into the base 2 under the guidance of the baffle 13 and be collected. Each time the exhaust filter 10 is started, the accumulated water in the base 2 will be pumped out together through the water suction pipe 71. When the water flow moves to the impeller 73, the water flow will push the impeller 73 to rotate. The impeller 73 will drive the turntable 74 to rotate. The turntable 74 will drive the pull rope 75 to wind around its own surface. The pull rope 75 will pull the inclined block 76 to move. The limiting plate 77 above the inclined block 76 will move downward along the inclined surface of the inclined block 76, so that the through hole on the limiting plate 77 moves out of the water suction pipe 71, and the water suction pipe 71 will no longer be driven by the exhaust filter 10 to pump water. At this time, the water flow will flow out through the mounting box 72, so that the water collected in the base 2 can be pumped out while replacing the air, preventing the water from accumulating and then contacting the transfer table 1, and indirectly contacting the discharged material, affecting the production quality; the bottom of the limiting plate 77 is in contact with the top of the inclined block 76.

One end of the water suction pipe 71 away from the exhaust filter 10 is communicated with the front and rear sides of the base 2;

[0027] Working principle: The water vapor in the replacement chamber body 4 will condense on the top wall inside the replacement chamber body 4, and the water droplets will be guided to both sides through the inclined surface on the top wall to prevent the water droplets from dripping directly after condensation. When the water droplets flow and drip to both sides, they will fall on the baffle 13 and slide down from both sides of the replacement chamber body 4 to the base 2 under the guidance of the baffle 13. Thus, it can effectively prevent the condensed water droplets in the replacement chamber from falling on the surface of the material. At the same time, when the replacement chamber body 4 is ventilated, the exhaust filter 10 will be started and the gas in the replacement chamber body 4 will be pumped out and discharged together through the exhaust pipe 6. The exhaust filter 10 has a frequency conversion function, which can adjust the size of the exhaust air volume, control the exhaust pressure of the replacement chamber, and will not affect the density of the product. Through the exhaust function of the exhaust filter 10, the replacement efficiency of the air in the replacement chamber is improved.

[0028] The water droplets condensed in the replacement chamber and the calciner 5 will eventually fall into the base 2 under the guidance of the baffle 13 and be collected. Each time the exhaust filter 10 is started, the accumulated water in the base 2 will be pumped out together through the water suction pipe 71.
