Description

Technical Field

[0001] This utility model relates to the field of high-temperature air collection technology, and in particular to a high-temperature air collection device for a high-temperature furnace. Background Technology

[0002] High-temperature furnaces generate high-temperature air during operation, with temperatures often reaching hundreds or even thousands of degrees Celsius. In traditional industrial production models, the enormous heat energy carried by this high-temperature air is mostly not effectively utilized and is instead directly discharged into the atmosphere. For example, in some metal smelting plants, the high-temperature air generated by high-temperature furnaces is directly discharged into the atmosphere, resulting in a large amount of heat energy being wasted. It is estimated that some enterprises lose 20% to 30% of their total energy costs due to the failure to recover the heat energy from high-temperature air.

[0003] Traditional high-temperature furnaces have low utilization rates of high-temperature air, and the fine impurities they contain can cause environmental pollution. Furthermore, traditional filtration devices require constant inspection of the internal filters by staff to prevent clogging and reduced filtration efficiency.

[0004] In view of this, we have studied and improved the existing problems to provide a high-temperature air collection device for high-temperature furnaces. The device has a reasonable structural design, high stability, and can be used in various aspects. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] This invention utilizes hot air delivery to drive a rotating shaft during equipment operation, thereby causing the filter screen to vibrate and beating through a movable block. This removes impurities from the filter screen surface, preventing internal clogging due to prolonged use. Furthermore, cleaning is performed while the equipment is running, reducing the frequency of equipment inspections by staff. This invention provides a high-temperature air collection device for high-temperature furnaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature air collection device for a high-temperature furnace, comprising a high-temperature furnace, a connecting pipe fixedly connected to the upper end of the high-temperature furnace, a filter chamber fixedly connected to the end of the connecting pipe away from the high-temperature furnace, a filter screen disposed inside the filter chamber, rotating shafts disposed at both ends inside the filter screen, a pulley A fixedly connected to one end of the rotating shaft, a belt disposed inside the pulley A, a pulley B connected to the end of the belt away from the pulley A, a reciprocating screw fixedly connected to the inner end of the pulley B, a movable block connected to the outer side of the reciprocating screw, a spring fixedly connected to one side of the movable block, a connecting rod fixedly connected to one end of the reciprocating screw, a spring rod fixedly connected to the end of the connecting rod away from the connection point, a connecting block fixedly connected inside the spring rod, a pump fixedly connected to one side of the filter chamber, an air outlet pipe fixedly connected to one end of the pump, a fan blade disposed inside the air outlet pipe, and a branch pipe fixedly connected to the outer side of the air outlet pipe.

[0007] Preferably, the high-temperature furnace and the filter chamber are connected by a connecting pipe made of high-temperature resistant material. The filter chamber is equipped with two sets of rotating shafts, and the filter screen is fixed by the two sets of rotating shafts. The filter screen is made of elastic material.

[0008] Preferably, the filter chamber is divided into two parts, with a slot on one side of its lower end. One end of the rotating shaft at the lower end of the filter chamber is fixedly connected to pulley A, which is connected to pulley B via a belt. The outer diameter of pulley A is larger than that of pulley B.

[0009] Preferably, the reciprocating screw is fixedly connected to one end of the pulley B, and the other end is connected to the inner wall of the filter chamber. Two sets of movable blocks are provided on the outside of the reciprocating screw, which are connected to the ball nut pair of the reciprocating screw. A fixed block is provided on one side of the movable block, and the fixed block is connected to the bottom of the filter chamber. The movable block is limited by being connected to the fixed block by a spring.

[0010] Preferably, the connecting rod is provided at both ends of the reciprocating screw, and there are two sets of them. Two sets of spring rods are fixedly connected to one end of the connecting rod, and the connecting block is fixed at one end of the connecting rod by the two sets of spring rods.

[0011] Preferably, the pump has a fixing plate at its lower end, which is connected to the filter chamber. The pump is fixed by connecting to the fixing plate. The air outlet pipe has a fan blade inside, which is connected to the rotating shaft at the lower end of the filter chamber. The air outlet pipe extends to the rear end of the fan blade.

[0012] Preferably, the branch pipe is fixedly connected to the outside of the air outlet pipe, and its branch pipe extends through the filter chamber to the lower end of the interior, and is aligned with the empty groove on one side of the filter chamber.

[0013] This invention has the following beneficial effects: Pulley B is connected to the reciprocating screw, so that when pulley B rotates, it drives the reciprocating screw to rotate synchronously. When the reciprocating screw rotates, it drives the movable blocks at both ends to move, and the movable blocks are limited by springs. Therefore, when the reciprocating screw rotates, it only drives the movable blocks to translate to both ends. Since connecting rods are fixedly connected to both ends of the reciprocating screw, the connecting rods rotate synchronously when the reciprocating screw rotates. When the connecting rods rotate, they cause the connecting blocks to contact the movable blocks, thus pushing the movable blocks to contact the filter screen and generate vibration. When the movable blocks contact the filter screen, the connecting rods continue to rotate, causing the connecting blocks to flip via the spring rod. When the connecting blocks disengage from pushing the movable blocks, the movable blocks will reset due to the force of the spring. This process repeats continuously, constantly striking and vibrating the filter screen, thereby removing impurities from the filter screen surface, preventing internal clogging of the filter screen due to prolonged use, and cleaning while the equipment is running, thus reducing the frequency of equipment inspections by staff.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5 This utility model provides an embodiment of a high-temperature furnace high-temperature air collection device, comprising a high-temperature furnace 1, a connecting pipe 2 fixedly connected to the upper end of the high-temperature furnace 1, a filter chamber 3 fixedly connected to the end of the connecting pipe 2 away from the high-temperature furnace 1, a filter screen 4 disposed inside the filter chamber 3, rotating shafts 5 disposed at both ends inside the filter screen 4, a pulley A6 fixedly connected to one end of the rotating shaft 5, a belt 7 disposed inside the pulley A6, a pulley B8 connected to the end of the belt 7 away from the pulley A6, and a pulley B8 fixedly connected to the inner end of the pulley B8. A reciprocating screw 9 is fixedly connected to the filter chamber 3. A movable block 10 is connected to the outside of the reciprocating screw 9. A spring 11 is fixedly connected to one side of the movable block 10. A connecting rod 12 is fixedly connected to one end of the reciprocating screw 9. A spring rod 13 is fixedly connected to the end of the connecting rod 12 away from the connection point. A connecting block 14 is fixedly connected inside the spring rod 13. A pump 15 is fixedly connected to one side of the filter chamber 3. An air outlet pipe 16 is fixedly connected to one end of the pump 15. A fan blade 17 is installed inside the air outlet pipe 16. A branch pipe 18 is fixedly connected to the outside of the air outlet pipe 16.

[0023] In an optional embodiment: the high-temperature furnace 1 and the filter chamber 3 are connected by a connecting pipe 2, which is made of high-temperature resistant material. The filter chamber 3 is equipped with two sets of rotating shafts 5, and the filter screen 4 is fixed by the two sets of rotating shafts 5. The filter screen 4 is made of elastic material. When in use, the hot air inside the high-temperature furnace 1 is transmitted through the connecting pipe 2, thereby entering the filter chamber 3 to filter the impurities carried inside the high-temperature air.

[0024] In an optional embodiment: the filter chamber 3 is divided into two parts, with a slot opened on one side of its lower end. One end of the rotating shaft 5 at the lower end of the filter chamber 3 is fixedly connected to a pulley A6. The pulley A6 is connected to a pulley B8 through a belt 7, and the outer diameter of the pulley A6 is larger than that of the pulley B8. When the rotating shaft 5 rotates, it will drive the pulley A6 to rotate synchronously. When the pulley A6 rotates, it will drive the pulley B8 to rotate synchronously through the belt 7. At the same time, because the outer diameter of the pulley A6 is larger than that of the pulley B8, when the pulley A6 drives the pulley B8 to rotate, the rotational speed of the pulley B8 is greater than that of the pulley A6.

[0025] In an optional embodiment: the reciprocating screw 9 is fixedly connected to one end of the pulley B8, and the other end is connected to the inner wall of the filter chamber 3. Two sets of movable blocks 10 are provided on the outside of the reciprocating screw 9, which are connected to the ball nut pair of the reciprocating screw 9. A fixed block is provided on one side of the movable block 10, which is connected to the bottom of the filter chamber 3. The movable block 10 is limited by the connection between the movable block 10 and the fixed block 11. When 6 drives 8 to rotate, because the pulley B8 is connected to the reciprocating screw 9, the rotation of the pulley B8 will drive the reciprocating screw 9 to rotate synchronously. When the reciprocating screw 9 rotates, it will drive the movable blocks 10 at both ends to move. The movable blocks 10 are limited by the springs 11, so when the reciprocating screw 9 rotates, it will only drive the movable blocks 10 to translate to both ends. The connecting rods 12 are fixed at both ends, so that when the reciprocating screw 9 rotates, the connecting rods 12 will rotate synchronously. When the connecting rods 12 rotate, the connecting block 14 will come into contact with the movable block 10, thereby pushing the movable block 10 to come into contact with the filter screen 4 and generating vibration. When the movable block 10 comes into contact with the filter screen 4, the connecting rods 12 continue to rotate, causing the connecting block 14 to flip through the spring rod 13. When the connecting block 14 is released from pushing the movable block 10, the movable block 10 will be reset by the force of the spring 11. This process is repeated to continuously knock and vibrate the filter screen 4, thereby removing impurities from the surface of the filter screen 4, preventing the filter screen 4 from becoming clogged after long-term use, and cleaning it while the equipment is running, thereby reducing the frequency of equipment inspection by the staff.

[0026] In an optional embodiment: the connecting rod 12 is provided at both ends of the reciprocating screw 9, and there are two sets of them. Two sets of spring rods 13 are fixedly connected to one end of the connecting rod 12. The connecting block 14 is fixed at one end of the connecting rod 12 by the two sets of spring rods 13. After the connecting block 14 is flipped, it will be reset by the spring rods 13, thereby preventing the movable block 10 from being unable to be pushed in the future.

[0027] In an optional embodiment: the pump 15 is provided with a fixing plate at its lower end, which is connected to the filter chamber 3. The pump 15 is fixed by connecting to the fixing plate. The air outlet pipe 16 is provided with a fan blade 17, which is connected to the rotating shaft 5 at the lower end of the filter chamber 3. The air outlet pipe 16 extends to the rear end of the fan blade 17. The pump 15 draws out the filtered hot air through the air outlet pipe 16 and then delivers it through the air outlet pipe 16. During the hot air delivery process, the fan blade 17 will be blown to rotate. Since the fan blade 17 is connected to the rotating shaft 5, when the fan blade 17 rotates, it will drive the rotating shaft 5 to drive the filter screen 4 to rotate continuously, thereby changing its position and preventing the filter screen 4 from being blocked due to long-term use on one side. At the same time, the hot air discharged through the air outlet pipe 16 can be used for ignition preheating or drying.

[0028] In an optional embodiment: the branch pipe 18 is fixedly connected to the outside of the air outlet pipe 16. The branch pipe 18 extends through the filter chamber 3 to the lower end of the interior and is aligned with the empty slot on one side of the filter chamber 3. When the pump 15 draws air, some of the air force will be transmitted through the branch pipe 18 to blow air onto the impact point and blow the fallen dust outward to prevent long-term accumulation from causing the internal parts to malfunction.

[0029] Working principle and process: During operation, the high-temperature furnace 1 transmits internal hot air through the connecting pipe 2, which then enters the filter chamber 3. Impurities carried inside are filtered through the filter screen 4. The pump 15 extracts the filtered hot air through the outlet pipe 16 and then transports it through the outlet pipe 16. During the hot air transport process, the fan blades 17 rotate. Because the fan blades 17 are connected to the rotating shaft 5, the rotation of the fan blades 17 drives the rotating shaft 5, causing the filter screen 4 to rotate continuously. The rotation of the rotating shaft 5 drives the pulley A6 to rotate synchronously. The rotation of pulley A6, in turn, drives the pulley B8 to rotate synchronously via the belt 7. Because the reciprocating screw 9 is fixedly connected to the connecting rod 12 at both ends, the reciprocating screw... When rod 9 rotates, it drives connecting rod 12 to rotate synchronously. When connecting rod 12 rotates, it causes connecting block 14 to contact movable block 10, thereby pushing movable block 10 to contact filter screen 4 and generate vibration. When movable block 10 is in contact with filter screen 4, connecting rod 12 continues to rotate, causing connecting block 14 to flip through spring rod 13. When connecting block 14 is released from pushing movable block 10, movable block 10 will be reset by the force of spring 11. This process is repeated to continuously knock and vibrate filter screen 4, thereby removing impurities from the surface of filter screen 4, preventing the filter screen 4 from becoming clogged after long-term use, and cleaning it while the equipment is running, thus reducing the frequency of equipment inspection by staff.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
