Description

Technical Field

[0001] The invention relates to the technical field of waste heat recovery equipment, and in particular to a heat recovery device for a dense furnace. Background Art

[0002] A dense furnace generally refers to a high-efficiency, well-sealed stove or heating equipment, which is designed to improve thermal efficiency, reduce energy waste, and enhance safety. A dense furnace heat recovery device is a device used to improve the efficiency of thermal energy utilization, and its main purpose is to recover and utilize the waste heat generated by the furnace during the heating process.

[0003] Among them, when recovering heat from a dense furnace, the recovered hot gas often contains harmful gases, and an adsorption device is usually required to adsorb the harmful gases. However, the exhaust gas usually also contains solid particles. When the adsorption device absorbs harmful gases, it will also adsorb the fixed particles. These solid particles may cause the adsorption port of the adsorption device to be blocked, affecting the transportation of hot gas. The adsorption device needs to be cleaned or replaced frequently, affecting the stable operation of the heat recovery device. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a heat recovery device for a dense furnace, comprising a power mechanism, the power mechanism also comprising a heating furnace, a transfer box is fixedly connected to the outer wall of the heating furnace, and a rotating drum is rotatably connected to the inner wall of the transfer box;

[0005] The reciprocating mechanism comprises a fixing ring fixedly connected to the outer wall of the rotating drum, three fixing rods are fixedly connected to the bottom of the fixing ring, and a cam groove is opened on the inner wall of the transfer box;

[0006] The pushing mechanism comprises a bevel ring slidably connected to the inner wall of the transfer box, six bevel blocks are fixedly connected to the top of the bevel ring, and three arc blocks are slidably connected to the bottom of the inner wall of the transfer box.

[0007] Preferably, the power mechanism also includes a gas pipe 1 fixedly connected to the top of the heating furnace, a gas pipe 2 fixedly connected to the top of the transfer box, a motor fixedly connected to the top of the gas pipe 2, and an adsorption filter element fixedly connected to the inner wall of the gas pipe 2.

[0008] Preferably, the power mechanism also includes fan blades fixedly connected to the bottom output end of the motor, three connecting rods are fixedly connected to the outer wall of the bottom output end of the motor, the side walls of the three connecting rods are fixedly connected to the inner wall of the rotating drum, a connecting ring is fixedly connected to the inner wall of the rotating drum, six exhaust holes are opened inside the rotating drum, and the waste heat generated by the operation of the heating furnace is transported to the transfer box through the air pipe, and then the motor is started to drive the fan blades to rotate. Since the connecting rod is installed on the outer wall of the output end of the motor, the rotating drum can be driven to rotate through the connecting rod. When the fan blades rotate, the hot air entering the transfer box will be sucked into the interior of the rotating drum, and the hot air will drive the particulate matter into the rotating drum together. When the rotating drum rotates, centrifugal force is generated, and the particulate matter is pushed to the inner wall of the rotating drum by the centrifugal force. When the fan blades rotate to push the air, the centrifugal force will cause the hot air to move along the center of the rotating drum. The combined effect of the two causes the hot air to flow not only radially but also with a rotational component. Since the rotation of the fan blades is usually continuous and stable, the airflow will rotate along the circumference of the drum, and the centrifugal force causes the air to gradually expand outward along the radius of the drum. This combined effect forms a spiral airflow, allowing the hot air to move upward along the inner wall of the drum. When the hot air and particulate matter move upward and come into contact with the connecting ring, they will be blocked by the connecting ring, allowing the hot air to move along the side wall of the connecting ring. When part of the hot air moves, it will drive the particulate matter into the exhaust hole. The hot air and particulate matter will move along the exhaust hole and be transported to the bottom of the transfer box through the exhaust pipe. Since the suction force of the fan blades on the bottom of the transfer box is reduced, larger particles will fall out of the transfer box due to gravity.

[0009] Preferably, the power mechanism also includes six exhaust pipes fixedly connected to the bottom of the drum, six exhaust holes are opened inside the drum, an arc cover is fixedly connected to the top of the connecting ring, and six arc tubes are fixedly connected to the inner wall of the arc cover, and another part of the hot air will move along the side wall of the connecting ring to the position of the arc cover. Since the exhaust holes opened in the arc cover will block the movement of particles, and since the particles spirally move at the bottom of the arc cover, a part of the airflow will enter the arc tube with the particles. When the hot air enters the arc tube, the arc tube will block the upward moving airflow, thereby allowing the hot air to move along the arc tube to the exhaust holes and finally be discharged into the transfer box. After the smaller particles fall to the bottom of the transfer box and are sucked up again, It moves along the arc cover and the connecting ring again, and then enters the exhaust hole again, falls to the bottom of the transfer box and is sucked up, and repeats this process. When the heating furnace stops, the motor will also stop, and the fan blades will stop rotating. The force attracting smaller particles will disappear, allowing the smaller particles to fall out of the transfer box. The hot air passing through the arc cover will enter the second gas pipeline, and the hot gas will be recovered and transported to the reuse device through the second gas pipeline. When the hot air passes through the adsorption filter element, the adsorption filter element will absorb the harmful gases in the hot air, and separate the solid particles in the hot air from the hot air, thereby reducing the burden on the adsorption device and preventing solid particles from adhering to the surface of the adsorption device, thereby reducing the number of cleaning and replacement times of the adsorption device and allowing the heat recovery device to operate stably.

[0010] Preferably, the reciprocating mechanism also includes a sliding ring arranged at the bottom of the fixed ring, the inner wall of the sliding ring is slidably connected to the outer wall of the fixed rod, three arc rods are slidably connected to the inner wall of the sliding ring, a connecting rod is fixedly connected to the outer wall of the sliding ring, the outer wall of the connecting rod is fixedly connected to the inner wall of the cam groove, after the transfer box is used for a long time, particulate matter may accumulate on the inner wall of the transfer box, when the drum rotates, it will drive the fixed ring to rotate, drive the fixed rod to rotate, and thus drive the sliding ring to rotate, when the sliding ring rotates, it will drive the connecting rod to rotate, and at the same time the connecting rod will slide in the cam groove, when the connecting rod slides along the cam groove, it will make the connecting rod move up and down, and at the same time drive the sliding ring to move, and the bevel ring will also move together, and when the bevel ring moves up and down, it will push the particulate matter on the inner wall of the transfer box to separate the particulate matter from the inner wall of the transfer box.

[0011] Preferably, the reciprocating mechanism also includes three arc springs fixedly connected to the inner wall of the sliding ring, the inner walls of the three arc rods are slidably connected to the outer wall of the fixed rod, and the three arc springs are fixedly connected to the side wall of the arc rod on one side away from the sliding ring, and the bottom of the sliding ring is fixedly connected to the top of the bevel ring. When the sliding ring rotates, the arc rod will be driven to rotate, and the arc rod will be affected by the centrifugal force when the sliding ring rotates, so that it will be thrown out and contact the transfer box. When the arc rod is thrown out, the arc spring will be stretched, allowing the arc spring to accumulate rebound force, so that the arc rod is tightly attached to the inner wall of the transfer box, and the inner wall of the transfer box is scraped, so that the attached particles are more easily scraped off the inner wall of the transfer box. By combining the two cleaning methods, the particles attached to the inner wall of the transfer box can be fully cleaned to avoid the particles from adhering to the transfer box, ensuring the smoothness of the inner wall of the transfer box, ensuring the smoothness of the hot air flow, and avoiding poor hot air flow, which affects the heat recovery efficiency.

[0012] Preferably, the pushing mechanism also includes a conical block fixedly connected to the top of the arc block, two spring telescopic blocks are slidably connected to the inner walls of the three arc blocks, the bottoms of the three arc blocks are fixedly connected to a sliding plate, and the side walls of the three sliding plates are fixedly connected to a return spring 1, and using the force of the descending bevel ring, when the bevel ring descends and the conical block, since the contact surfaces of the bevel ring and the conical block are both bevels, the bevel ring will smoothly push the conical block to move, so that the conical block is close to the center of the transfer box, driving the arc block and the spring telescopic block to move, and also driving the sliding plate to move, pulling the return spring 1 to move, and when the arc block moves, the spring telescopic blocks will be close to each other, thereby squeezing each other between the spring telescopic blocks, so that the arc blocks form a circle, pushing the particles at the bottom of the transfer box to the discharge outlet and discharged from the transfer box.

[0013] Preferably, the pushing mechanism also includes a sliding sleeve fixedly connected to the outer wall of the exhaust pipe, the inner walls of the six sliding sleeves are slidably connected with an air injection pipe, the tops of the six air injection pipes are fixedly connected with a fixed sleeve, the side walls of the six fixed sleeves are slidably connected with a spring return rod, and the side walls of the six sliding sleeves are fixedly connected with a return spring 2. By utilizing the force of the movement of the arc block, when the arc block approaches the center of the transfer box, the arc block will contact the spring return rod during the movement, pushing the spring return rod to move, driving the fixed sleeve to move, and when the fixed sleeve moves, it will drive the air injection pipe to move close to the exhaust pipe. When the fixed sleeve moves, it will also squeeze the return spring 2 until the air injection pipe is fitted with the exhaust pipe. After fitting, when the bevel ring continues to descend, the bevel of the bevel ring will separate from the bevel of the conical block.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the characteristic that the rotating drum can separate the particulate matter in the hot air, and transmits the waste heat generated by the operation of the heating furnace to the transfer box through the gas pipeline, and then starts the motor to drive the fan blades to rotate, which drives the rotating drum to rotate. When the fan blades rotate, the hot air entering the transfer box will be sucked into the interior of the rotating drum, and the hot air will drive the particulate matter into the rotating drum. Since centrifugal force is generated when the rotating drum rotates, the particulate matter is pushed toward the inner wall of the rotating drum by the centrifugal force. While the fan blades rotate to push the air, the centrifugal force will cause the hot air to move along the center of the rotating drum toward the outer wall of the rotating drum. The combined effect of the two causes the flow of the hot air to be not only radial There is also a rotational component. Since the rotation of the fan blades is usually continuous and stable, the airflow will rotate along the circumference of the drum, and the centrifugal force causes the air to gradually expand outward along the radius of the drum. This combined effect forms a spiral airflow, allowing the hot air to move upward along the inner wall of the drum. When the hot air and particles move upward and contact the connecting ring, they will be blocked by the connecting ring, allowing the hot air to move along the side wall of the connecting ring. When part of the hot air moves, it will drive the particles into the exhaust hole. The hot air and particles will move along the exhaust hole and be transported to the bottom of the transfer box through the exhaust pipe. Since the bottom of the transfer box is affected by the fan blades, The suction force will decrease, and the larger particles will fall out of the transfer box due to gravity. Another part of the hot air will move along the side wall of the connecting ring to the position of the arc cover. Since the exhaust holes opened in the arc cover will block the movement of the particles, and because the particles spirally move at the bottom of the arc cover, a part of the airflow will carry the particles into the arc tube. When the hot air enters the arc tube, the arc tube will block the upward airflow, so that the hot air moves along the arc tube to the exhaust holes and finally discharged from the transfer box. After the smaller particles fall to the bottom of the transfer box and are sucked up again, they will move along the arc cover and the connecting ring again, and then enter the exhaust holes again. , falls to the bottom of the transfer box and is sucked up, and this cycle repeats. When the heating furnace stops, the motor will also stop, the fan blades will stop rotating, and the force attracting smaller particles will disappear, allowing smaller particles to fall out of the transfer box. The hot air passing through the arc cover will enter the gas pipe 2, and the hot gas will be recovered and transported to the reuse device through the gas pipe 2. When the hot air passes through the adsorption filter element, the adsorption filter element will absorb the harmful gases in the hot air, and reduce the burden of the adsorption device by separating the solid particles in the hot air from the hot air, thereby preventing solid particles from adhering to the surface of the adsorption device, thereby reducing the number of cleaning and replacement times of the adsorption device, and making the heat recovery device run stably.

[0016] (2) After the transfer box of the present invention has been used for a long time, particulate matter may accumulate on the inner wall of the transfer box. When the rotating drum rotates, it will drive the fixed ring to rotate, drive the fixed rod to rotate, and then drive the sliding ring to rotate. When the sliding ring rotates, it will drive the connecting rod to rotate, and at the same time, the connecting rod will slide in the cam groove. When the connecting rod slides along the cam groove, it will make the connecting rod reciprocate up and down, and at the same time drive the sliding ring to move, and the bevel ring will also move together. When the bevel ring reciprocates up and down, it will push the particulate matter on the inner wall of the transfer box to separate the particulate matter from the inner wall of the transfer box. When the sliding ring rotates, it will drive the arc When the rod rotates, the arc rod will be affected by the centrifugal force when the sliding ring rotates, and will be thrown out and contact the transfer box. When the arc rod is thrown out, the arc spring will be stretched, allowing the arc spring to accumulate resilience, so that the arc rod will fit tightly against the inner wall of the transfer box, scraping the inner wall of the transfer box, making it easier for the attached particles to be scraped off the inner wall of the transfer box. By combining the two cleaning methods, the particles attached to the inner wall of the transfer box can be fully cleaned to avoid particles adhering to the transfer box, ensuring the smoothness of the inner wall of the transfer box, ensuring the smoothness of the hot air flow, and avoiding poor hot air flow that affects the heat recovery efficiency.

[0017] (3) The present invention utilizes the force of the descending bevel ring. When the bevel ring descends and contacts the conical block, since the contact surfaces of the bevel ring and the conical block are both beveled, the bevel ring will smoothly push the conical block to move, allowing the conical block to approach the center of the transfer box, driving the arc block and the spring expansion block to move, and also driving the sliding plate to move, pulling the reset spring to move. When the arc block moves, the spring expansion blocks will approach each other, thereby squeezing each other, so that the arc blocks form a circle, pushing the particles at the bottom of the transfer box to the discharge port and discharging them into the transfer box, avoiding that the particles on the inner wall of the transfer box are scraped off and gathered at the bottom of the transfer box. Too much accumulation may cause the fan blades to attract too much particles when attracting hot air, affecting the circulation of smaller particles, and may cause the arc cover to be blocked, affecting the hot air from entering the gas transmission pipe 2.

[0018] (4) The present invention utilizes the force of the arc block moving. When the arc block approaches the center of the transfer box, the arc block will contact the spring return rod during the movement, pushing the spring return rod to move, driving the fixed sleeve to move, and when the fixed sleeve moves, it will drive the gas injection pipe to move close to the exhaust pipe. When the fixed sleeve moves, it will also squeeze the return spring 2 until the gas injection pipe fits with the exhaust pipe. After fitting, when the bevel ring continues to descend, the bevel of the bevel ring will separate from the bevel of the conical block, so that when the bevel ring descends, it will not push the conical block to move. Because when the bevel ring descends, it will also bring The movable inclined plane block descends, and when the inclined plane block contacts the spring return rod, it will squeeze the spring return rod, causing the spring return rod to descend, compressing the gas in the fixed sleeve, and injecting it into the exhaust pipe through the gas injection pipe to back-blow the exhaust pipe to prevent the hot air flow rate in the exhaust pipe from being lower than the flow rate in the exhaust hole, which may cause particles to accumulate in the exhaust pipe. Back-blow can cause the particles attached to the exhaust pipe to shake and fall off, avoiding exhaust pipe blockage, affecting the smooth airflow, and causing the particles sucked into the drum to be unable to be discharged smoothly, affecting the normal operation of the drum.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-Figure 4 The present invention is a heat recovery device for a dense furnace, comprising a power mechanism 1, the power mechanism 1 further comprising a heating furnace 101, a transfer box 102 is fixedly connected to the outer wall of the heating furnace 101, and a rotating drum 103 is rotatably connected to the inner wall of the transfer box 102;

[0032] The reciprocating mechanism 2 includes a fixing ring 201 fixedly connected to the outer wall of the rotating drum 103, three fixing rods 202 are fixedly connected to the bottom of the fixing ring 201, and a cam groove 203 is opened on the inner wall of the transfer box 102;

[0033] The pushing mechanism 3 comprises a bevel ring 301 slidably connected to the inner wall of the transfer box 102 , six bevel blocks 302 are fixedly connected to the top of the bevel ring 301 , and three arc blocks 303 are slidably connected to the bottom of the inner wall of the transfer box 102 .

[0034] The power mechanism 1 also includes a gas pipe 104 fixedly connected to the top of the heating furnace 101, a gas pipe 2 106 fixedly connected to the top of the transfer box 102, a motor 105 fixedly connected to the top of the gas pipe 106, and an adsorption filter element 107 fixedly connected to the inner wall of the gas pipe 106.

[0035] The power mechanism 1 also includes a fan blade 108 fixedly connected to the output end of the bottom of the motor 105. Three connecting rods are fixedly connected to the outer wall of the output end of the bottom of the motor 105. The side walls of the three connecting rods are fixedly connected to the inner wall of the rotating drum 103. The inner wall of the rotating drum 103 is fixedly connected to a connecting ring 109. Six exhaust holes 110 are opened inside the rotating drum 103 to transport the waste heat generated by the operation of the heating furnace 101 to the transfer box 102 through the gas pipe 104, and then the motor 10 is started. 5 drives the fan blades 108 to rotate. Since a connecting rod is installed on the outer wall of the output end of the motor 105, the rotating drum 103 can be driven to rotate through the connecting rod. When the fan blades 108 rotate, the hot air entering the transfer box 102 will be sucked into the interior of the rotating drum 103. The hot air will drive the particles into the rotating drum 103. When the rotating drum 103 rotates, centrifugal force is generated. The hot air and particles are pushed to the inner wall of the rotating drum 103 by the centrifugal force. When the fan blades 108 rotate and push the air, the centrifugal force will The hot air is made to move along the center of the drum 103 toward the outer wall of the drum 103. The combined effect of the two causes the hot air flow to be not only radial but also to have a rotational component. Since the rotation of the fan blades 108 is usually continuous and stable, the airflow will rotate along the circumference of the drum 103, and the centrifugal force causes the air to gradually expand outward along the radius of the drum. This combined effect forms a spiral airflow, allowing the hot air to move upward along the inner wall of the drum 103. When the hot air and particulate matter move upward and contact the connecting ring 109, they will be blocked by the connecting ring 109, allowing the hot air to move along the side wall of the connecting ring 109. When part of the hot air moves, it will drive the particulate matter into the exhaust hole 110. The hot air and particulate matter will move along the exhaust hole 110 and be transported to the bottom of the transfer box 102 through the exhaust pipe 111. Since the suction force of the fan blades 108 on the bottom of the transfer box 102 is reduced, larger particles will fall out of the transfer box 102 due to gravity.

[0036] The power mechanism 1 also includes six exhaust pipes 111 fixedly connected to the bottom of the rotating drum 103, six exhaust holes 110 are opened inside the rotating drum 103, and an arc cover 112 is fixedly connected to the top of the connecting ring 109. Six arc tubes 113 are fixedly connected to the inner wall of the arc cover 112. Another part of the hot air will move along the side wall of the connecting ring 109 to the position of the arc cover 112. Since the exhaust holes opened in the arc cover 112 will block the movement of particles, and since the particles spirally move at the bottom of the arc cover 112, a part of the airflow will carry the particles into the arc tube 113. When the hot air enters the arc tube 113, the arc tube 113 will block the upward moving airflow, thereby allowing the hot air to move along the arc tube 113 to the exhaust holes 110 and finally be discharged from the transfer box 102, while the smaller particles fall to the bottom of the transfer box 102. After being sucked up again, it will move along the arc cover 112 and the connecting ring 109 again, and then enter the exhaust hole 110 again, fall to the bottom of the transfer box 102 and be sucked up, and repeat this process. When the heating furnace 101 stops, the motor 105 will also stop, and the fan blades 108 will stop rotating. The force attracting smaller particles will disappear, allowing the smaller particles to fall out of the transfer box 102. The hot air passing through the arc cover 112 will enter the gas pipe 106, and the hot air will be recovered and transported to the reuse device through the gas pipe 106. When the hot air passes through the adsorption filter element 107, the adsorption filter element 107 will absorb the harmful gases in the hot air, and reduce the burden on the adsorption device by separating the solid particles in the hot air from the hot air, and avoid the solid particles from adhering to the surface of the adsorption device, thereby reducing the number of cleaning and replacement times of the adsorption device, so that the heat recovery device can operate stably.

[0037] For example 2, please refer to Figure 5-Figure 8 The present invention is a heat recovery device for a dense furnace. On the basis of Example 1, the reciprocating mechanism 2 further includes a sliding ring 204 arranged at the bottom of the fixed ring 201. The inner wall of the sliding ring 204 is slidably connected to the outer wall of the fixed rod 202. Three arc-shaped rods 206 are slidably connected to the inner wall of the sliding ring 204. A connecting rod 205 is fixedly connected to the outer wall of the sliding ring 204. The outer wall of the connecting rod 205 is fixedly connected to the inner wall of the cam groove 203. After the transfer box 102 is used for a long time, particulate matter may accumulate on the inner wall of the transfer box 102. When the cam 203 rotates, the fixing ring 201 is driven to rotate, the fixing rod 202 is driven to rotate, and the sliding ring 204 is driven to rotate. When the sliding ring 204 rotates, the connecting rod 205 is driven to rotate, and the connecting rod 205 slides in the cam groove 203. When the connecting rod 205 slides along the cam groove 203, the connecting rod 205 moves up and down, and the sliding ring 204 is driven to move, and the bevel ring 301 also moves together. When the bevel ring 301 moves up and down, it pushes the particles on the inner wall of the transfer box 102, so that the particles are separated from the inner wall of the transfer box 102.

[0038] The reciprocating mechanism 2 also includes three arc springs 207 fixedly connected to the inner wall of the sliding ring 204. The inner walls of the three arc rods 206 are all slidably connected to the outer wall of the fixed rod 202. The sides of the three arc springs 207 away from the sliding ring 204 are all fixedly connected to the side walls of the arc rods 206. The bottom of the sliding ring 204 is fixedly connected to the top of the bevel ring 301. When the sliding ring 204 rotates, it will drive the arc rods 206 to rotate. The arc rods 206 will be affected by the centrifugal force of the sliding ring 204 when rotating, so that they are thrown out and contact the transfer box 102. When the arc rod 206 is thrown out, the arc spring 207 will be stretched, allowing the arc spring 207 to accumulate resilience, so that the arc rod 206 is in close contact with the inner wall of the transfer box 102, and the inner wall of the transfer box 102 is scraped, so that the attached particles are more easily scraped off the inner wall of the transfer box 102. By combining the two cleaning methods, the particles attached to the inner wall of the transfer box 102 can be fully cleaned to prevent the particles from adhering to the transfer box 102, thereby ensuring the smoothness of the inner wall of the transfer box and ensuring the smoothness of the hot air flow, thereby avoiding poor hot air flow and affecting the heat recovery efficiency.

[0039] The pushing mechanism 3 also includes a conical block 304 fixedly connected to the top of the arc block 303, two spring telescopic blocks 305 are slidably connected to the inner walls of the three arc blocks 303, and the bottoms of the three arc blocks 303 are fixedly connected to sliding plates 306. The side walls of the three sliding plates 306 are fixedly connected to return springs 307. By utilizing the descending force of the bevel ring 301, when the bevel ring 301 descends and the conical block 304, the bevel ring 301 will smoothly move because the contact surfaces of the bevel ring 301 and the conical block 304 are both beveled. The conical block 304 is pushed to move, so that the conical block 304 is close to the center of the transfer box, driving the arc block 303 and the spring expansion block 305 to move, and also driving the sliding plate 306 to move, pulling the reset spring 307 to move, and when the arc block 303 moves, the spring expansion blocks 305 are brought close to each other, so that the spring expansion blocks 305 are squeezed against each other, so that the arc blocks 303 and the arc blocks 303 form a circle, pushing the particles at the bottom of the transfer box 102 to the discharge port, and discharged from the transfer box 102.

[0040] The pushing mechanism 3 also includes a sliding sleeve 308 fixedly connected to the outer wall of the exhaust pipe 111, and the inner walls of the six sliding sleeves 308 are all slidably connected to the gas injection pipe 309, and the tops of the six gas injection pipes 309 are all fixedly connected to the fixed sleeves 310, and the side walls of the six fixed sleeves 310 are all slidably connected to the spring return rod 311, and the side walls of the six sliding sleeves 308 are all fixedly connected to the return spring 2 312. By using the force of the arc block 303 moving, when the arc block 303 is close to the center of the transfer box 102 When the center is at the center, the arc block 303 will contact the spring return rod 311 during movement, pushing the spring return rod 311 to move, driving the fixed sleeve 310 to move, and when the fixed sleeve 310 moves, it will drive the gas injection pipe 309 to move close to the exhaust pipe 111. When the fixed sleeve 310 moves, it will also squeeze the return spring 312 until the gas injection pipe 309 is fitted with the exhaust pipe 111. After fitting, when the bevel ring 301 continues to descend, the bevel of the bevel ring 301 will separate from the bevel of the conical block 304.

[0041] A specific application of this embodiment is as follows: when the present invention is used, the waste heat generated by the operation of the heating furnace 101 is transported to the transfer box 102 through the gas pipe 104, and then the motor 105 is started to drive the fan blades 108 to rotate. Since a connecting rod is installed on the outer wall of the output end of the motor 105, the connecting rod can drive the rotating drum 103 to rotate. When the fan blades 108 rotate, the hot air entering the transfer box 102 will be sucked into the interior of the rotating drum 103, and the hot air will drive the particles into the rotating drum 103 together. Since centrifugal force is generated when the rotating drum 103 rotates, the particles are pushed toward the inner wall of the rotating drum 103 by the centrifugal force. While the fan blades 108 rotate to push the air, the centrifugal force will cause the hot air to move along the center of the rotating drum 103 to the outside of the rotating drum 103 The combined effect of the two causes the hot air flow to be not only radial but also rotational. Since the rotation of the fan blades 108 is usually continuous and stable, the airflow will rotate along the circumference of the drum 103, and the centrifugal force causes the air to gradually expand outward along the radius of the drum. This combined effect forms a spiral airflow, allowing the hot air to move upward along the inner wall of the drum 103. When the hot air and particulate matter move upward and contact the connecting ring 109, they will be blocked by the connecting ring 109, allowing the hot air to move along the side wall of the connecting ring 109. When a part of the hot air moves, it will drive the particulate matter into the exhaust hole 110. The hot air and particulate matter will move along the exhaust hole 110 and be transported to the transfer At the bottom of the transfer box 102, since the suction force of the fan blades 108 on the bottom of the transfer box 102 will be reduced, larger particles will fall out of the transfer box 102 due to gravity, and another part of the hot air will move along the side wall of the connecting ring 109 to the position of the arc cover 112. Since the exhaust holes opened in the arc cover 112 will block the movement of the particles, and since the particles spirally move at the bottom of the arc cover 112, a part of the airflow will carry the particles into the arc tube 113. When the hot air enters the arc tube 113, the arc tube 113 will block the upward moving airflow, so that the hot air moves along the arc tube 113 to the exhaust hole 110, and finally discharged from the transfer box 102, and the smaller particles will be sucked up again after falling to the bottom of the transfer box 102 After that, it will move along the arc cover 112 and the connecting ring 109 again, and then enter the exhaust hole 110 again, fall to the bottom of the transfer box 102 and be sucked up, and repeat this process. When the heating furnace 101 stops, the motor 105 will also stop, and the fan blades 108 will stop rotating. The force of attracting smaller particles disappears, allowing the smaller particles to fall out of the transfer box 102. The hot air passing through the arc cover 112 will enter the gas pipe 106, and the hot air will be recovered and transported to the reuse device through the gas pipe 106. When the hot air passes through the adsorption filter element 107, the adsorption filter element 107 will absorb the harmful gases in the hot air, and reduce the burden of the adsorption device by separating the solid particles in the hot air from the hot air, and prevent the solid particles from adhering to the surface of the adsorption device.Thereby reducing the cleaning and replacement times of the adsorption device and making the heat recovery device operate stably;

[0042] After the transfer box 102 is used for a long time, particles may accumulate on the inner wall of the transfer box 102. When the rotating drum 103 rotates, it drives the fixed ring 201 to rotate, drives the fixed rod 202 to rotate, and then drives the sliding ring 204 to rotate. When the sliding ring 204 rotates, it drives the connecting rod 205 to rotate, and at the same time, the connecting rod 205 slides in the cam groove 203. When the connecting rod 205 slides along the cam groove 203, it makes the connecting rod 205 move up and down, and drives the sliding ring 204 to move, and the bevel ring 301 also moves together. When the bevel ring 301 moves up and down, it pushes the particles on the inner wall of the transfer box 102, so that the particles are separated from the inner wall of the transfer box 102. When the sliding ring 204 rotates, , will drive the arc rod 206 to rotate, and the arc rod 206 will be affected by the centrifugal force when the sliding ring 204 rotates, so that it is thrown out and contacts the transfer box 102. When the arc rod 206 is thrown out, the arc spring 207 will be stretched, so that the arc spring 207 accumulates resilience, so that the arc rod 206 is closely attached to the inner wall of the transfer box 102, and the inner wall of the transfer box 102 is scraped, so that the attached particles are more easily scraped off the inner wall of the transfer box 102. By combining the two cleaning methods, the particles attached to the inner wall of the transfer box 102 can be fully cleaned, and the particles are prevented from adhering to the inside of the transfer box 102, ensuring the smoothness of the inner wall of the transfer box, ensuring the smoothness of the hot air flow, and avoiding the poor hot air flow, which affects the heat recovery efficiency;

[0043] When the bevel ring 301 descends and the conical block 304, since the contact surfaces of the bevel ring 301 and the conical block 304 are both beveled, the bevel ring 301 will smoothly push the conical block 304 to move, so that the conical block 304 is close to the center of the transfer box, driving the arc block 303 and the spring expansion block 305 to move, and also driving the sliding plate 306 to move, pulling the reset spring 307 to move, and when the arc block 303 moves, the spring expansion blocks 305 will be close to each other, so that the spring expansion blocks 305 can move closer to each other. The shrink blocks 305 squeeze each other, so that the arc blocks 303 and the arc blocks 303 form a circle, pushing the particles at the bottom of the transfer box 102 to the discharge port and discharging them from the transfer box 102, avoiding the particles on the inner wall of the transfer box 102 from being scraped off and gathering at the bottom of the transfer box. Too much gathering may cause the fan blades 108 to attract too much particles when attracting hot air, affecting the circulation of smaller particles, and may cause the arc cover 112 to be blocked, affecting the hot air from entering the gas pipe 106;

[0044] When the arc block 303 is close to the center of the transfer box 102, the arc block 303 will contact the spring return rod 311 during its movement, thereby pushing the spring return rod 311 to move, driving the fixed sleeve 310 to move, and when the fixed sleeve 310 moves, it will drive the gas injection pipe 309 to move close to the exhaust pipe 111, and when the fixed sleeve 310 moves, it will also squeeze the return spring 2 312 until the gas injection pipe 309 fits with the exhaust pipe 111. After fitting, when the bevel ring 301 continues to descend, the bevel of the bevel ring 301 will separate from the bevel of the conical block 304, so that when the bevel ring 301 descends, it will not push the conical block 304 to move. The surface block 302 descends, and when the inclined surface block 302 contacts the spring return rod 311, it will squeeze the spring return rod 311, causing the spring return rod 311 to descend, compressing the gas in the fixed sleeve 310, and injecting it into the exhaust pipe 111 through the gas injection pipe 309, and back-blowing the exhaust pipe 111 to prevent the hot air flow rate in the exhaust pipe 111 from being lower than the flow rate in the exhaust hole 110, causing particles to accumulate in the exhaust pipe 111. Back-blowing can cause the particles attached to the exhaust pipe 111 to shake and fall off, thereby preventing the exhaust pipe 111 from being blocked, affecting the smooth airflow, and causing the particles sucked into the drum 103 to be unable to be discharged smoothly, affecting the normal operation of the drum 103.
