DETAILED DESCRIPTION

[0043] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0044] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0045] Reference Figure 1-Figure 13 As shown, an autoclave waste gas recovery device for environmentally friendly bricks, the recovery device comprises: an autoclave body 100, a heat exchange mechanism 200 for recovering and utilizing the waste gas heat in the autoclave body 100, and a filtering mechanism 300 for filtering and cleaning harmful substances and particulate matter in the waste gas; wherein, a conduit 101 is fixedly connected to the side of the autoclave body 100, the conduit 101 is connected to the heat exchange mechanism 200 through a first connecting pipe 102, and the filtering mechanism 300 is connected to the heat exchange mechanism 200.

[0046] In the above scheme, during the production process of environmentally friendly bricks, a large amount of high-temperature residual gas will be generated inside the autoclave body 100. These residual gases contain rich heat energy and possible harmful substances and particulate matter. The conduit 101 fixedly connected to the side of the autoclave body 100 will lead out the generated high-temperature residual gas to ensure the stability of the internal pressure of the autoclave and avoid waste of heat energy. Through the first connecting pipe 102, the high-temperature residual gas led out by the conduit 101 is introduced into the heat exchange mechanism 200. In the heat exchange mechanism 200, the residual gas exchanges heat with other media, transfers heat energy to water, and realizes heat recovery. In the heat exchange mechanism 200, the heat in the residual gas is absorbed by water or other media, and the water temperature gradually increases. In this process, the temperature of the residual gas is reduced, but the harmful substances and particulate matter it carries are not removed. The residual gas treated by the heat exchange mechanism 200 enters the filter mechanism 300 through the pipeline to reduce pollution emissions.

[0047] Reference Figure 1-Figure 5As shown, the heat exchange mechanism 200 includes: a heat exchange box 201, a water storage tank 202, a heat exchange tube 203, an air outlet pipe 204, a water outlet 205 and a water inlet 206; wherein, the water storage tank 202 is coaxially arranged inside the heat exchange box 201, the surface of the water storage tank 202 is provided with a spiral heat exchange tube 203, and the top surface thereof is fixedly provided with a water inlet 206, and the bottom surface thereof is fixedly provided with a water outlet 205, the air inlet end of the heat exchange tube 203 is connected with the first connecting tube 102, and the air outlet end of the heat exchange tube 203 is connected with the filtering mechanism 300 through the air outlet pipe 204, and the water storage tank 202 is provided with a stirring component 400 for stirring the liquid in the water storage tank 202 so that it is heated evenly.

[0048] In the above scheme, the high-temperature residual gas derived from the autoclave body 100 enters the air inlet end of the heat exchange tube 203 of the heat exchange mechanism 200 through the first connecting pipe 102. In the heat exchange box 201, the residual gas flows in the spiral heat exchange tube 203 and exchanges heat with the liquid in the water storage tank 202. Since the heat exchange tube 203 is designed in a spiral shape, the contact area and contact time between the gas and the liquid are increased, and the heat exchange efficiency is improved. At the same time, the stirring component 400 in the water storage tank 202 starts to work, stirring the liquid to ensure that the liquid is heated evenly, further improving the heat exchange effect. As the heat exchange proceeds, the liquid in the water storage tank 202 gradually heats up and absorbs most of the heat in the residual gas. The temperature of the residual gas gradually decreases, but still maintains a certain temperature and pressure. After heat exchange, the residual gas passes through the outlet end of the heat exchange tube 203 and the outlet pipe 204, and is led to the filter mechanism 300 for further processing. The hot water in the water storage tank 202 can be discharged through the water outlet 205 and used in other occasions requiring heating, such as preheating raw materials, heating, etc. At the same time, new cold water is continuously replenished into the water storage tank 202 through the water inlet 206, forming a cycle.

[0049] Reference Figure 5 As shown, the stirring assembly 400 includes: a rotating motor 401, a rotating shaft 402 and a stirring rod 403; wherein, the rotating motor 401 is fixedly arranged on the top surface of the heat exchange box 201, and its output shaft is coaxially arranged vertically downward with the heat exchange box 201 and the top end is fixedly connected to the rotating shaft 402 through a coupling, and a plurality of stirring rods 403 are spaced apart on the surface of the rotating shaft 402, and the top surface of the stirring rod 403 is in contact with the inner wall of the water storage tank 202.

[0050] When the heat exchange mechanism 200 starts working, the rotating motor 401 fixed to the top surface of the heat exchange box 201 is started. The output shaft of the rotating motor 401 is fixedly connected to the rotating shaft 402 through a shaft coupling, so the power of the rotating motor 401 is directly transmitted to the rotating shaft 402. As the rotating motor 401 runs, the rotating shaft 402 starts to rotate. The multiple stirring rods 403 spaced apart on the surface of the rotating shaft 402 also rotate accordingly. The top surface of the stirring rod 403 contacts the inner wall of the water storage tank 202 to ensure that the liquid in the water storage tank can be fully stirred during the rotation process. The rotation of the stirring rod 403 drives the liquid in the water storage tank 202 to generate flow and vortex, so that the liquid and the residual gas in the heat exchange tube 203 can have a more sufficient heat exchange. At the same time, the stirring effect also helps to distribute the heat inside the liquid more evenly, avoiding local overheating or uneven temperature problems. During the entire working process of the heat exchange mechanism 200, the rotating motor 401 continues to operate and the stirring rod 403 continuously stirs the liquid to ensure the efficiency and stability of the heat exchange process. As the heat exchange proceeds, the liquid in the water tank 202 gradually heats up and is discharged through the water outlet 205 for use in other production links.

[0051] Reference Figure 4-Figure 6 As shown, the filtering mechanism 300 includes: a filter box 301, an exhaust pipe 302, a first solenoid valve 303, a circulation pipe 304, a second solenoid valve 305, a filter screen 306 and an activated carbon plate 307; wherein the filter box 301 is connected to the heat exchange pipe 203 through the air outlet pipe 204, and a filter screen 306 is slidably provided on the inner wall thereof, and an activated carbon plate 307 is fixedly provided on the inner wall of the filter box 301 located above the filter screen 306, an exhaust pipe 302 and a circulation pipe 304 are fixedly provided on the top of the filter box 301, a first solenoid valve 303 is provided in the exhaust pipe 302, a second solenoid valve 305 is provided in the circulation pipe 304, and the air outlet end thereof is connected to the conduit 101, and a vibration component 500 for driving the filter screen 306 to vibrate up and down along the filter box 301 is also provided in the filter box 301.

[0052] In the above scheme, the treated residual gas enters the filter box 301 of the filter mechanism 300 from the outlet pipe 204. The residual gas first encounters the filter screen 306, which can intercept and remove large particles and impurities in the residual gas to achieve preliminary filtration. The residual gas after preliminary filtration continues to rise and encounters the activated carbon plate 307 fixed on the upper inner wall of the filter box 301. The activated carbon plate 307 uses its strong adsorption capacity to further remove harmful substances in the residual gas, such as gaseous pollutants, odors, etc., to achieve deep filtration. The filtered gas accumulates in the filter box 301 and is ready to be discharged through the exhaust pipe 302. During the filtration process, the vibration component 500 will be started regularly or as needed to drive the filter screen 306 to vibrate up and down along the filter box 301. This action helps to shake off and remove particles and impurities attached to the filter screen 306, prevent the filter screen 306 from being blocked, and maintain its filtration efficiency. The first solenoid valve 303 and the second solenoid valve 305 are set to achieve intelligent detection and circulation treatment of gas. When the gas does not meet the emission standards, it can be automatically returned to the autoclave for further processing until it meets the standards.

[0053] Reference Figure 4 and Fig.12 As shown, a gas detection device 309 for detecting gas content and temperature is fixedly provided on the inner top wall of the filter box 301, and a first controller 308 is also fixedly provided on the filter box 301, and the first controller 308 is electrically connected to the gas detection device 309, wherein, when the gas detection device 309 detects that the gas content and temperature after treatment are qualified, the first controller 308 controls the first solenoid valve 303 to open and discharge the gas from the exhaust pipe 302; when the gas detection device 309 detects that the gas content or temperature after treatment is unqualified, the first controller 308 controls the first solenoid valve 303 to close and opens the second solenoid valve 305 at the same time, so that the gas in the filter box 301 passes through the circulation pipe 304 and enters the conduit 101 again for circulation treatment.

[0054] In the above scheme, the gas processed by the filter mechanism 300 first enters the filter box 301 before being discharged, and is detected by the gas detection device 309 fixed to the inner top wall. The gas detection device 309 mainly detects whether the content and temperature of the gas meet the preset qualified standards, and the gas detection device 309 transmits the detected data to the first controller 308 in real time. The first controller 308 processes and analyzes the received data according to the preset qualified standards to determine whether the content and temperature of the gas are qualified. If the gas content and temperature detected by the gas detection device 309 meet the preset qualified standards, the first controller 308 will issue an instruction to control the first solenoid valve 303 to open. At this time, the gas in the filter box 301 is smoothly discharged into the atmosphere through the opened exhaust pipe 302. If one or more of the gas content or temperature detected by the gas detection device 309 does not meet the preset qualified standards, the first controller 308 will immediately issue an instruction to control the first solenoid valve 303 to close to prevent unqualified gas from being discharged into the atmosphere. At the same time, the first controller 308 also controls the second solenoid valve 305 to open, so that the gas in the filter box 301 re-enters the conduit 101 of the autoclave body 100 through the circulation pipe 304 for further processing until the gas content and temperature reach the qualified standards.

[0055] Reference Figure 7-Figure 8 As shown, the vibration assembly 500 includes: a spring column 502, a drive motor 503, a drive shaft 504, an eccentric wheel 505, a connecting rod 506, a movable column 507, a push rod 508 and a sliding sleeve 509; wherein, the inner side wall of the filter box 301 is provided with a slide groove 501 for the filter screen 306 to slide, and the inner wall of the slide groove 501 is fixedly provided with multiple groups of spring columns 502 at intervals, and the top of the spring column 502 is vertically upward and fixedly connected to the bottom surface of the filter screen 306, and the outlet side of the filter box 301 is fixedly connected to the filter screen 306. A driving motor 503 is provided, whose output shaft is arranged horizontally and the top end is fixedly connected to the driving shaft 504 through a shaft coupling, an eccentric wheel 505 is fixedly sleeved on the driving shaft 504, the side surface of the eccentric wheel 505 is rotatably connected to one end of a connecting rod 506, the other end of the connecting rod 506 is rotatably connected to a movable column 507, a top end of the movable column 507 is fixedly provided with a push rod 508, the push rod 508 is slidably sleeved in a sliding sleeve 509, and the sliding sleeve 509 is fixedly provided on the bottom surface of the filter screen 306.

[0056] When in use, the drive motor 503 is started, and the drive motor 503 transmits its power to the drive shaft 504 through the shaft coupling. As the drive motor 503 runs, the drive shaft 504 starts to rotate, driving the eccentric wheel 505 fixedly sleeved on the drive shaft 504 to rotate synchronously, and the side of the eccentric wheel 505 is rotatably connected to one end of the connecting rod 506. Therefore, when the eccentric wheel 505 rotates, the eccentric motion of its side is transmitted to the movable column 507 through the connecting rod 506. The other end of the connecting rod 506 is rotatably connected to the movable column 507, so that the movable column 507 can generate reciprocating motion in the horizontal direction. A top rod 508 is fixedly provided at the top of the movable column 507, and the top rod 508 is slidably sleeved in a sliding sleeve 509 fixed to the bottom surface of the filter screen 306. As the movable column 507 reciprocates, the push rod 508 will slide up and down in the sliding sleeve 509, thereby pushing the filter 306 to vibrate up and down along the slide 501 opened on the inner wall of the filter box 301. A plurality of groups of spring columns 502 are fixedly arranged at intervals on the inner wall of the slide 501, and the top of the spring column 502 is fixedly connected to the bottom surface of the filter 306. During the vibration process, the spring column 502 will play a role of buffering and assisting vibration, making the vibration of the filter 306 more uniform and powerful. Through the linkage of the above-mentioned mechanism, the filter 306 can continuously vibrate up and down, thereby shaking off and removing the particles and impurities attached to its surface, and realizing the automatic cleaning function.

[0057] Reference Figure 9-10 As shown, the filter box 301 is also provided with a cleaning component 600 for cleaning impurities when impurities are adhered to the filter 306, and the cleaning component 600 includes: an electric telescopic rod 601, a mounting plate 602, a cleaning brush 603 and a scraper 604; wherein, the electric telescopic rod 601 is fixedly arranged on the inner wall of the filter box 301 between the filter 306 and the activated carbon plate 307, and its output end is horizontally arranged and the top end is fixedly connected to the mounting plate 602, and the bottom surface of the mounting plate 602 is spaced apart with a cleaning brush 603 and a scraper 604, and the bottom surfaces of the cleaning brush 603 and the scraper 604 are in contact with the surface of the filter 306, and the bottom surface of the mounting plate 602 is also provided with a crushing piece for crushing impurities attached to the filter 306.

[0058] When it is detected that there are many impurities adhering to the filter 306, the electric telescopic rod 601 fixed on the inner wall of the filter box 301 is started. The output end of the electric telescopic rod 601 starts to move horizontally, driving the mounting plate 602 at its top to move together. As the mounting plate 602 moves, the cleaning brush 603 fixed on its bottom surface first contacts the surface of the filter 306. The bristles of the cleaning brush 603 can preliminarily brush away the particles and impurities attached to the surface of the filter 306, preparing for the subsequent deep cleaning. After the cleaning brush 603 preliminarily cleans, the scraper 604 fixed on the bottom surface of the mounting plate 602 continues to contact and slide with the surface of the filter 306. The scraper 604 can scrape away more stubborn impurities and residues on the filter 306 to achieve deep cleaning. During the movement of the mounting plate 602, the crushing piece will crush the impurities scraped off the filter 306 and break them into smaller particles for subsequent processing or discharge.

[0059] Reference Figure 10-11 As shown, the crushing parts include: a crushing roller 605, a mounting frame 606, a rack 607 and a gear 608; wherein, a mounting frame 606 is fixedly provided on the bottom surface of the mounting plate 602, a crushing roller 605 is rotatably provided on the mounting frame 606, gears 608 are provided at both ends of the rotating shaft of the crushing roller 605, and racks 607 are fixedly provided on the two inner side walls of the filter box 301 that are away from each other, and the rack 607 is meshed with the gear 608.

[0060] In the above scheme, when the cleaning assembly 600 starts working, the electric telescopic rod 601 is first started, pushing the mounting plate 602 and all the components thereon to move toward the filter 306. As the mounting plate 602 moves, the crushing roller 605 fixed on the mounting frame 606 gradually approaches and contacts the surface of the filter 306. At this time, the roller surface of the crushing roller 605 contacts the impurities on the filter 306. Gears 608 are provided at both ends of the rotating shaft of the crushing roller 605. These gears 608 are meshed with the rack 607 fixed on the inner wall of the filter box 301. When the mounting plate 602 moves, the gear 608 rolls along the rack 607, thereby driving the crushing roller 605 to rotate. As the crushing roller 605 rotates, the impurities attached to the filter 306 are crushed. The impurities are crushed into smaller particles for subsequent processing or discharge. The electric telescopic rod 601 continues to push the mounting plate 602 and the components thereon to move on the surface of the filter 306, while the crushing roller 605 continues to rotate to perform the crushing operation. The cleaning brush 603 and the scraper 604 also work synchronously to complete the cleaning task of the filter screen 306 together.

[0061] Reference Figure 4-Figure 13As shown, a pressure sensor 610 is fixedly provided on the bottom surface of the filter 306, and a gas detection device 309 is provided on the filter box 301. The pressure sensor 610 is electrically connected to the second controller 609. When the detection value of the pressure sensor 610 exceeds a preset pressure threshold range, the second controller 609 controls the drive motor 503 to turn off and simultaneously starts the electric telescopic rod 601, so that the electric telescopic rod 601 drives the mounting plate 602 to move back and forth, and the filter 306 is cleaned by the cleaning brush 603, the scraper 604 and the crushing piece.

[0062] In the above solution, the second controller 609 receives the detection value from the pressure sensor 610 and compares it with the preset pressure threshold range. This pressure threshold range is set according to the normal working conditions of the filter 306 and the expected impurity accumulation. When the detection value of the pressure sensor 610 exceeds the preset pressure threshold range, it means that too many impurities may have accumulated on the filter 306, resulting in increased pressure. At this time, the second controller 609 will make an abnormal response.

[0063] First, the second controller 609 sends a signal to the drive motor 503 to control it to shut down. This is to prevent the vibration of the vibration component 500 from interfering with the cleaning operation during the cleaning process. Subsequently, the second controller 609 sends a signal to the electric telescopic rod 601 to start its work. The output end of the electric telescopic rod 601 begins to telescopically move, driving the mounting plate 602 to move back and forth on the surface of the filter 306. As the mounting plate 602 moves, the cleaning brush 603, the scraper 604 and the crushing piece fixed to its bottom surface begin to work. The cleaning brush 603 removes impurities, the scraper 604 removes stubborn impurities, and the crushing piece crushes the impurities. During the entire cleaning process, the pressure sensor 610 continuously monitors the pressure of the filter 306. If the pressure value still exceeds the threshold range, the cleaning operation will continue; once the pressure value drops to the normal range, the second controller 609 will control the electric telescopic rod 601 to stop working, and may restart the drive motor 503 to restore the normal operation of the vibration component 500.

[0064] Reference Figure 4-Figure 5 As shown, a guide plate 104 is fixedly provided inside the conduit 101, and the opening of the guide plate 104 is a cone that gradually converges from right to left toward the axial center line of the conduit 101, and a shunt pipe 105 is fixedly provided at the right end opening of the guide plate 104, and the shunt pipe 105 is connected to the first connecting pipe 102 through the second connecting pipe 103.

[0065] In the above scheme, the residual gas generated by the autoclave is first introduced through the conduit 101. At this time, the gas enters the conduit 101 at a certain flow rate and flow direction. A guide plate 104 is fixedly provided in the conduit 101, and its opening is designed to be a cone that gradually converges from right to left toward the axis of the conduit 101. This design allows the gas entering the conduit 101 to be diverted under the guidance of the guide plate 104, and a part of the central gas passes through the guide plate 104 and enters the diverter pipe 105, thereby improving the efficiency of gas treatment.

[0066] In summary, the autoclave residual gas recovery device for environmentally friendly bricks provided by the present invention, when in use, the residual gas generated by the autoclave is first introduced through the conduit 101, and the gas entering the conduit 101 is diverted under the guidance of the guide plate 104, and a part of the central gas passes through the guide plate 104 and enters the diverter pipe 105, and then enters the heat exchange box 201, in the heat exchange box 201, the residual gas flows in the spiral heat exchange tube 203, and exchanges heat with the liquid in the water storage tank 202. Since the heat exchange tube 203 is designed in a spiral shape, the contact area and contact time between the gas and the liquid are increased, and the heat exchange efficiency is improved. At the same time, the rotating motor 401 is started, and as the rotating motor 401 runs, the rotating shaft 402 starts to rotate. Multiple stirring rods 403 spaced apart on the surface of the rotating shaft 402 also rotate accordingly. The top surface of the stirring rod 403 contacts the inner wall of the water tank 202 to ensure that the liquid in the water tank 202 can be fully stirred during the rotation. The rotation of the stirring rod 403 drives the liquid in the water tank 202 to generate flow and vortex, so that the liquid and the residual gas in the heat exchange tube 203 can have a more sufficient heat exchange. The treated residual gas enters the filter box 301 of the filter mechanism 300 from the outlet pipe 204. The residual gas first encounters the filter screen 306. The filter screen 306 can intercept and remove large particles and impurities in the residual gas to achieve preliminary filtration. The residual gas after preliminary filtration continues to rise and encounters the activated carbon plate 307 fixed on the upper inner wall of the filter box 301. The activated carbon plate 307 uses its powerful adsorption capacity to further remove harmful substances in the residual gas. At this time, the drive motor 503 is started, and the drive shaft 504 starts to rotate, driving the eccentric wheel 505 fixedly mounted on the drive shaft 504 to rotate synchronously. The eccentric motion of the side surface is transmitted to the movable column 507 through the connecting rod 506, so that the movable column 507 can generate reciprocating motion in the horizontal direction, and the top rod 508 slides up and down in the sliding sleeve 509, thereby pushing the filter 306 to vibrate up and down along the slide 501 opened on the inner wall of the filter box 301. A plurality of groups of spring columns 502 are fixedly arranged at intervals on the inner wall of the slide 501. The filter 306 can continuously vibrate up and down, thereby shaking off and removing particles and impurities attached to its surface. The first controller 308 processes and analyzes the received data according to the preset qualified standards to determine whether the gas content and temperature are qualified. If the gas content and temperature detected by the gas detection device 309 meet the preset qualified standards, the first controller 308 will issue an instruction to control the first solenoid valve 303 to open. At this time, the gas in the filter box 301 is smoothly discharged into the atmosphere through the opened exhaust pipe 302. When it is detected that there are a lot of impurities adhering to the filter 306, the electric telescopic rod 601 fixed on the inner wall of the filter box 301 is started to drive the mounting plate 602 on its top to move together. As the mounting plate 602 moves, the cleaning brush 603 fixed on its bottom surface first contacts the surface of the filter 306.The bristles of the cleaning brush 603 can initially remove particles and impurities attached to the surface of the filter 306, preparing for subsequent deep cleaning. After the cleaning brush 603 performs preliminary cleaning, the scraper 604 fixed to the bottom surface of the mounting plate 602 continues to contact and slide with the surface of the filter 306. The scraper 604 can scrape off more stubborn impurities and residues on the filter 306, achieving deep cleaning.
