Description

Technical Field

[0001] The invention belongs to the technical field of rotary furnaces, and more specifically, particularly relates to a sealed energy-saving high-temperature rotary furnace. Background Art

[0002] High temperature rotary furnace is an important equipment widely used in metallurgy, chemical industry, building materials and other industries. It is made of high temperature resistant materials, usually with a metal shell lined with refractory bricks or ceramic fibers and other insulation materials. In practical applications, rotary furnace equipment usually requires the following technologies:

[0003] 1. The furnace body is cylindrical and can rotate around the central axis;

[0004] 2. Transmission device, used to drive the furnace body to rotate;

[0005] 3. The supporting device, which consists of supporting wheels, rollers, etc., is used to support the furnace body and ensure its smooth rotation;

[0006] 4. Sealing device, used to prevent gas leakage in the furnace and external air from entering the furnace;

[0007] 5. Combustion device, used to provide the heat required for heating in the furnace.

[0008] The high-temperature rotary kiln has a large furnace volume and can process a large amount of materials at one time. It is suitable for large-scale production. The rotating motion of the furnace body causes the materials to tumble and mix continuously in the furnace, ensuring that the materials are heated evenly and improving the product quality. During the use of the equipment, it has the following shortcomings:

[0009] 1. The furnace body of the high-temperature rotary kiln needs to rotate continuously to ensure uniform heating and reaction of the materials. At the same time, the inside of the furnace body needs to maintain a continuous heating state, resulting in high overall energy consumption of the high-temperature rotary kiln, increasing the initial investment cost of the equipment and increasing production costs.

[0010] 2. The refractory materials of high-temperature rotary kilns are prone to cracking, peeling and other damage when subjected to high temperature and thermal shock for a long time, which will accelerate the damage of the refractory materials, not only affecting the normal operation of the equipment, but also reducing the service life of the equipment. Summary of the invention

[0011] In order to solve the above technical problems, the present invention provides a sealed energy-saving high-temperature rotary kiln to solve the above problems.

[0012] A sealed energy-saving high-temperature rotary furnace comprises a rotary furnace body and a driving module, wherein a side plate is rotatably mounted on the side end of the rotary furnace body, an air guide tube is fixedly mounted on the side end of the side plate, a closing cylinder is slidably mounted on the side end of the air guide tube, a fixed ring tube is fixedly mounted on the side end of the side plate, a supporting tube is fixedly mounted inside the fixed ring tube, a transmission shaft is rotatably mounted on the side end of the driving module, a first ring is slidably mounted on the surface of the transmission shaft, a second ring is rotatably mounted on the side end of the first ring, and a recovery module is fixedly mounted on the bottom end of the driving module.

[0014] Preferably, a threaded ring is rotatably installed on the surface of the sealing sleeve, two docking tubes are fixedly installed on the side ends of the sealing sleeve, two positioning plates are fixedly installed on the surface of the sliding sleeve, two light strips are fixedly installed on the side ends of each of the positioning plates, a guide rod is fixedly installed on the side ends of each of the positioning plates, at least two connecting wires are fixedly installed on the end of each of the guide rods, the fixed ring tube is a multi-layer design, at least two nozzles are fixedly installed on the side ends of the fixed ring tube, the surface of the transmission shaft is provided with a guide groove, and the transmission shaft rotates synchronously with the first ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the gear barrel is driven to rotate by the rotation of the first ring, and the output shaft of the gear barrel is connected to the transmission box, and the transmission box is connected to the recovery module. A generator and a frequency converter are installed inside the recovery module. The continuous rotation of the rotary furnace body itself is used to drive the generator inside the drive module to rotate, and the mechanical energy is converted into electrical energy. The current is guided to the inside of the rotary furnace body through the frequency converter and provided to the electric heating device inside the rotary furnace body, thereby reducing the overall energy consumption of the rotary furnace body and reducing the use cost of the equipment.

[0017] In the present invention, a plurality of airflows are formed at the side ends of the fixed ring tube through the through connection of the support tube, so as to quickly dissipate the heat of the rotary furnace body. At the same time, the drive shaft is driven to rotate by the drive module, thereby driving the rotary furnace body to rotate. The side plates remain stationary at the side ends of the drive shaft, and the airflow blown out from the side ends of the fixed ring tube can accelerate the cooling of the rotary furnace body and increase the service life of the equipment.

[0018] In the present invention, the pressure inside the rotary furnace body is increased by heating, and the thrust generated on the sliding sleeve is greater, which pushes the guide rod to move inside the connecting line. After the generated force breaks the connecting line, two light bars are installed on the side end of the positioning plate, and one side of the guide rod is disconnected from the docking tube, which triggers the light bar to be energized. Multiple light bars are lit at the side end of the positioning plate to warn the staff that the pressure inside the rotary furnace body is too high, thereby increasing the safety of use.

[0019] In the present invention, the telescopic rod is driven to extend and retract, so that the telescopic rod applies a thrust to the holder, and the holder drives the second ring to slide on the surface of the transmission shaft. At the same time, the inner wall of the second ring is designed to be smooth. The second ring is sleeved on the surface of the fixed ring tube and does not rotate with the transmission shaft. The push rod generates a thrust on the gear tube, which automatically closes the air guide tube without affecting the normal rotation of the first ring and the transmission shaft.

[0029] A transmission box 14 is fixedly installed on the top of the recovery module 13, and a gear cylinder 15 is rotatably installed on the side end of the transmission box 14.

The airflow enters the interior of the fixed ring tube 26 through the air guide tube 18. At the same time, multiple nozzles are installed on the side end of the fixed ring tube 26. The nozzles are evenly distributed on the side end of the fixed ring tube 26. The airflow is transported to the nozzles through the support tube 27. The surface of the transmission shaft 16 is provided with a guide groove, and the transmission shaft 16 rotates synchronously with the first ring 23.

[0031] Working principle:

[0032] In the first step, the material to be processed is added into the rotating rotary furnace body 11 through the feeding device, and the material enters the interior of the rotary furnace body 11 at a uniform speed. The rotary furnace body 11 is made of high-temperature resistant metal materials as a whole. A heating mechanism is installed inside the rotary furnace body 11. The heating system heats the rotary furnace body 11 to raise the temperature to the required working temperature. The material inside the rotary furnace body 11 is dried, roasted, and sintered at high temperature. At the same time, a motor is installed inside the driving module 12, and the output end of the motor is connected to the transmission shaft 1 6 is connected to drive the transmission shaft 16 to rotate. Support wheels and rollers are installed on the outside of the rotary furnace body 11 to make the rotary furnace body 11 rotate slowly to ensure that the materials are evenly heated and reacted. A sealing sleeve 28 is installed on the side end of the rotary furnace body 11. A threaded ring 31 is rotatably installed on the surface of the sealing sleeve 28. The threaded ring 31 is rotatably connected to the sealing sleeve 28 through a thread. The rotating threaded ring 31 squeezes the sealing sleeve 28 to increase the sealing performance of the side end of the rotary furnace body 11 to prevent gas leakage in the furnace and entry of outside air.

[0033] Sealing mechanisms are installed at both ends of the rotary furnace body 11. The interior of the rotary furnace body 11 is sealed. The sealing sleeve 28 and the sliding sleeve 29 are sleeve-connected. At the same time, the sealing sleeve 28 and the sliding sleeve 29 are energized through a wiring harness. During the heating process of the material, the pressure inside the rotary furnace body 11 increases, and the air pressure pushes the two sliding sleeves 29. One end of the sliding sleeve 29 is fan-shaped to increase the contact surface. At the same time, the sliding sleeve 29 can slide inside the sealing sleeve 28. The sliding sleeve 29 slides outward, driving the two positioning plates 33 to move. The positioning plates 33 pull the guide rods 35 to the butt pipes 32. , and at the same time, the movement of the guide rod 35 pulls the top of the connecting line 36. Since the greater the pressure inside the rotary furnace body 11, the greater the thrust generated on the sliding sleeve 29, the guide rod 35 is pushed to move inside the connecting line 36. After the generated force breaks the connecting line 36, two light strips 34 are installed on the side end of the positioning plate 33, and one side of the guide rod 35 is disconnected from the docking tube 32, triggering the light strip 34 to be energized. Multiple light strips 34 are lit at the side end of the positioning plate 33, warning the staff that the pressure inside the rotary furnace body 11 is too high, thereby increasing the safety of use.

[0034] In the second step, a side plate 17 is rotatably installed at the side end of the rotary furnace body 11, and the top of the air guide pipe 18 is connected to the blasting device through a pipeline. A fixed ring pipe 26 and a support pipe 27 are installed on the inner side of the side plate 17, both of which are made of heat-resistant materials. At the same time, the support pipe 27 runs through the interior of the fixed ring pipe 26, and the top of the support pipe 27 is connected to the air guide pipe 18. The airflow enters the interior of the fixed ring pipe 26 through the air guide pipe 18. At the same time, a plurality of nozzles are installed at the side end of the fixed ring pipe 26, and the nozzles are evenly distributed at the side end of the fixed ring pipe 26. The tube 27 conveys airflow to the nozzle and enters the interior of the rotary furnace body 11. The fixed ring tube 26 is a multi-layer ring design, which is connected through the support tube 27. Multiple airflows are formed at the side end of the fixed ring tube 26 to quickly dissipate heat for the rotary furnace body 11. At the same time, the drive shaft 16 is driven to rotate through the drive module 12 to drive the rotary furnace body 11 to rotate. The side plate 17 remains stationary at the side end of the drive shaft 16, and cooperates with the airflow blown out from the side end of the fixed ring tube 26 to accelerate the cooling of the rotary furnace body 11 and increase the service life of the equipment.

[0035] A sealing sleeve 28 is installed inside the air guide tube 18, and one end of the closing tube 25 is rotatably connected to the top end of the push rod 22. By driving the telescopic rod 19 to extend and retract, the telescopic rod 19 applies a thrust to the card seat 21, so that the card seat 21 drives the second ring 24 to slide on the surface of the transmission shaft 16. At the same time, the inner wall of the second ring 24 is a smooth design. The second ring 24 is sleeved on the surface of the fixed ring tube 26 and does not rotate with the transmission shaft 16. At the same time, the side end of the second ring 24 is rotatably installed with the first ring 23. The inner side of the first ring 23 is clamped with the guide groove on the surface of the transmission shaft 16. The first ring 23 rotates synchronously with the transmission shaft 16 and also rotates freely at the side end of the second ring 24. By pushing the second ring 24 to move, the second ring 24 pushes the push rod 22 to deflect, and the deflected push rod 22 pushes the closing tube 25. The side end portion of the closing cylinder 25 slides into the interior of the air duct 18 and can close the air duct 18 by itself. The first ring 23 and the gear cylinder 15 are in a clamping state. The rotation of the first ring 23 drives the gear cylinder 15 to rotate. At the same time, the output shaft of the gear cylinder 15 is connected to the transmission box 14, and the transmission box 14 is connected to the recovery module 13. A generator and a frequency converter are installed inside the recovery module 13. One end of the engine is connected to the output end of the gear cylinder 15 through a gear to drive the generator to rotate. The continuous rotation of the rotary furnace body 11 itself drives the generator inside the drive module 12 to rotate, converting mechanical energy into electrical energy, and then guiding the current to the interior of the rotary furnace body 11 through the frequency converter, and providing it to the electric heating device inside the rotary furnace body 11, thereby reducing the overall energy consumption of the rotary furnace body 11 and reducing the use cost of the equipment.
