Description

Technical Field

[0001] This invention relates to the field of hot blast stove feeding technology, and more specifically to an adjustable hot blast stove feeding device. Background Technology

[0002] A hot air furnace is a device used to generate hot air, widely used in industrial production and daily life. It heats air by burning fuels (such as coal, oil, gas, etc.) and then delivers the generated hot air to the space or equipment that needs to be heated. The main components of a hot air furnace include a combustion chamber, heat exchanger, fan, and control system. In the industrial field, hot air furnaces are often used in processes such as drying, baking, and smelting. For example, in the food processing industry, hot air furnaces can be used to dry grains.

[0003] However, the limited space inside the combustion chamber makes it easy for fuel entering the combustion chamber through the feeding device to accumulate. When too much fuel accumulates, it will not be able to burn completely. During the combustion process, the fuel will produce waste residue. If this waste residue is not cleaned up in time, it will accumulate in the combustion chamber, further reducing the space capacity for subsequent new fuel to enter. This not only reduces the combustion efficiency of the combustion chamber, but also affects its energy supply effect. In addition, if the hot blast stove cannot be replenished with fuel in time during operation, its heating capacity will be greatly weakened, directly affecting the reduction of industrial production efficiency.

[0004] Therefore, this invention proposes an adjustable hot blast stove feeding device to achieve intelligent separation of fuel and slag in the combustion chamber and automatic feeding of the combustion chamber, ensuring fuel supply and combustion efficiency of the hot blast stove and maintaining stable operation of industrial production. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable hot blast stove feeding device to solve the problem of how to achieve intelligent separation of fuel and slag in the combustion chamber and automatic feeding of the combustion chamber, thereby ensuring the fuel supply and combustion efficiency of the hot blast stove.

[0006] The present invention provides the following technical solution: an adjustable hot air furnace feeding device, comprising a furnace body, wherein a combustion chamber and a waste collection chamber are arranged sequentially from top to bottom in the furnace body, and a combustion assembly and a waste collection assembly are respectively installed in the combustion chamber and the waste collection chamber. A fuel conveying assembly is installed on one side of the furnace body. The end of the fuel conveying assembly near the furnace body is connected to a lifting drive assembly and an oscillating drive assembly for transmission. The lifting drive assembly and the oscillating drive assembly are located outside the combustion chamber and the waste collection chamber, respectively. In addition, a material distribution plate is provided in the combustion assembly. When the fuel conveying assembly transmits fuel, it can drive the lifting drive assembly and the oscillating drive assembly to rotate simultaneously. On the one hand, the driving lifting drive assembly can carry the material distribution plate to move back and forth in the combustion assembly to turn the combustion assembly and accelerate the separation of fuel and waste. On the other hand, the driving oscillating drive assembly can push the waste collection assembly to oscillate back and forth to level the collected waste.

[0007] The combustion assembly includes a storage tank, a waste discharge funnel, an igniter, and elastic telescopic components. The storage tank is slidably disposed in the combustion chamber, and a waste discharge funnel is installed on the bottom wall of the storage tank. In addition, an igniter is installed on the inner wall of the storage tank, and symmetrically distributed elastic telescopic components are provided on the left and right sides of the bottom of the storage tank. Furthermore, channels for the elastic telescopic components to pass through are opened on the left and right sides of the waste discharge funnel to avoid interference between the waste discharge funnel and the elastic telescopic components when the waste discharge funnel sinks with the storage tank.

[0008] The fuel conveying assembly includes a drive roller, a support frame, a conveyor belt, a material conveying trough, and a motor. The support frame is installed on the side wall of the furnace body. The upper and lower support frames are rotatably connected to the drive roller. The ends of the conveyor belt are respectively connected to the drive roller. The lower support frame is longer than the upper support frame, so that the conveyor belt is in an inclined and raised state. The surface of the conveyor belt is provided with a material conveying trough. The lower drive roller is fixedly connected to the output shaft of the motor through a coupling.

[0009] The lifting transmission assembly includes a turntable, a swing arm, a slide block, a receiving tube, and a connecting rod. The turntable is fixedly sleeved on the end of the transmission roller, and a protruding rod is provided on the outer edge of the turntable. One end of the swing arm is rotatably connected to the protruding rod, while the other end of the swing arm is movably engaged with the slide block. The slide block is slidably connected to the slide rail on the side wall of the furnace body. The bottom wall of the slide block is equipped with a receiving tube and a connecting rod movably inserted into the receiving tube. The receiving tube passes through the slide groove on the side wall of the storage trough and is fixedly connected to the material distribution plate. In addition, the side wall of the furnace body has a window for the connecting rod to be raised and lowered. The transmission roller can carry the turntable to rotate coaxially. Then, when the protruding rod on the outer edge of the turntable rotates around its wheel center, it can lift the swing arm to swing left and right. The other end of the swing arm pushes the slide block to move horizontally back and forth along the side wall of the furnace body, so that the slide block carries the retractable receiving tube and the connecting rod to move left and right as a whole. This allows the connecting rod to slide horizontally back and forth in the inner cavity of the storage trough with the material distribution plate, which on the one hand realizes material turning and avoids the problem of incomplete combustion caused by fuel accumulation, and on the other hand realizes automatic waste discharge.

[0010] Furthermore, the waste collection assembly includes a waste collection box, a second spring, and a guide slide rod. The waste collection box is equipped with a second spring on its left and right sides, so that the waste collection box can be connected to the furnace body via the second spring. The top of the front and rear sides of the waste collection box is fixedly connected to the guide slide rod, which is horizontally slidably arranged in a groove on the side wall of the furnace body.

[0011] Furthermore, the oscillation transmission assembly includes a pusher block, pulleys, a synchronous belt, a rotating shaft, and a shaft seat. The shaft seat is fixedly connected to the outer wall of the furnace body. The pusher block is rotatably connected to the shaft seat via the rotating shaft. Both the rotating shaft and the transmission roller are equipped with pulleys, which are connected by a synchronous belt. A push rod is fixedly connected to the pusher block. The transmission roller can carry the pulleys to rotate coaxially. The upper and lower pulleys are connected by a synchronous belt, which causes the lower pusher block, pulleys, and rotating shaft to rotate coaxially. During rotation, the push rod on the outer edge of the pusher block will intermittently push the guide slide rod, causing the waste collection box connected to the guide slide rod to oscillate back and forth in the furnace body by means of a second spring, so as to flatten the waste slag received in the waste collection box and improve the utilization rate of the recycling space.

[0012] Furthermore, the bottom wall of the storage tank is provided with sieve holes, so that the residual waste residue can pass through the sieve holes and be introduced into the waste collection box by the waste discharge funnel for collection.

[0013] Furthermore, the material distribution plate is horizontally slidably disposed inside the furnace body, and the upper and lower layers of the material distribution plate are respectively provided with a grid and a brush plate.

[0014] Furthermore, the elastic telescopic component includes a positioning tube, a piston rod, and a first spring. The positioning tube is fixedly installed on the inner wall of the furnace body, and a piston rod is movably inserted into the positioning tube. The plug at the bottom end of the piston rod is connected to the bottom wall of the positioning tube by a first spring, and the top end of the piston rod is fixedly connected to the storage trough.

[0015] Furthermore, a signal transmitter is also installed at the top of the piston rod, and a signal receiver is embedded in the inner wall of the furnace body. A controller is also installed on the outer wall of the furnace body. As the amount of fuel in the storage tank changes, its counterweight changes continuously, causing the storage tank to rise or sink in the furnace body. During this process, the signal transmitter will pair with the upper and lower signal receivers to generate and output different judgment information to the controller to execute the control command of feeding or stopping the material.

[0016] Furthermore, a feed chute is installed on the side of the furnace body near the fuel delivery assembly, above the combustion assembly, and the feed chute is always located above the storage tank, so that the material can be introduced into the storage tank from the feed chute on the side wall of the furnace body.

[0017] Furthermore, the top of the furnace body is provided with a heat exhaust port, through which heat flow can be delivered to the space or equipment that needs to be heated to provide energy. The bottom front wall of the furnace body is provided with a flip-up hatch.

[0018] The technical effects and advantages of this invention are as follows:

[0019] This invention, by incorporating a combustion assembly, a waste collection assembly, a lifting transmission assembly, and a vibration transmission assembly, facilitates the following: when the equipment requires fuel supply, the conveyor belt can circulate materials from bottom to top via its surface troughs, unloading at the conveying inflection point and automatically feeding the storage trough. Simultaneously, the drive rollers carry the turntable in a coaxial rotation. The convex rod on the outer edge of the turntable rotates around its wheel center, lifting the swing arm to swing left and right. The other end of the swing arm pushes the slide block to move horizontally back and forth along the side wall of the furnace, allowing the slide block, carrying the retractable receiving tube and connecting rod, to move left and right as a whole. This allows the connecting rod to slide horizontally back and forth within the storage trough, carrying the material distribution plate. This serves two purposes: firstly, it enables material turning, preventing incomplete combustion caused by fuel accumulation; secondly, it facilitates automatic waste discharge. Simultaneously, the transmission roller carries the pulleys in a coaxial rotation. The upper and lower pulleys are connected by a synchronous belt, causing the push block, pulleys, and shaft below to rotate coaxially. During rotation, the push rod on the outer edge of the push block intermittently pushes the guide slide rod, causing the waste collection box connected to the guide slide rod to oscillate back and forth within the furnace body using the second spring. This flattens the waste slag received in the waste collection box, improving the utilization rate of the recycling space. Attached Figure Description

The furnace body 1 contains a combustion chamber and a waste collection chamber arranged sequentially from top to bottom. A combustion assembly 2 and a waste collection assembly 3 are respectively installed in the combustion chamber and waste collection chamber. A fuel conveying assembly 4 is installed on one outer side of the furnace body 1. The end of the fuel conveying assembly 4 near the furnace body 1 is connected to a lifting transmission assembly 5 and an oscillating transmission assembly 6. The lifting transmission assembly 5 and the oscillating transmission assembly 6 are located outside the combustion chamber and waste collection chamber, respectively. Furthermore, a material distribution plate 8 is provided inside the combustion assembly 2. When the fuel conveying assembly 4 transmits fuel, it can drive the lifting transmission assembly 5 and the oscillating transmission assembly 6 to rotate simultaneously. On one hand, the lifting transmission assembly 5 can carry the material distribution plate 8 to reciprocate within the combustion assembly 2 to turn the combustion assembly 2 and accelerate the separation of fuel and waste. On the other hand, the oscillating transmission assembly 6 can push the waste collection assembly 3 to oscillate back and forth to level the collected waste.

[0030] In this embodiment, it should be specifically noted that a feeding chute located above the combustion assembly 2 is installed on the side of the furnace body 1 near the fuel conveying assembly 4, and the feeding chute is always located above the storage tank 201, so that the material can be introduced into the storage tank 201 from the feeding chute on the side wall of the furnace body 1.

[0032] The outer wall of the furnace body 1 is also equipped with a controller 7, which is used to receive the judgment information output by the signal receiver 206, and output control commands to the actuator through analysis and processing.

[0033] Reference Figure 2-5 The combustion assembly 2 includes a storage tank 201, a waste discharge funnel 202, an igniter 203, and elastic telescopic members 204. The storage tank 201 is slidably disposed in the combustion chamber, and the waste discharge funnel 202 is installed on the bottom wall of the storage tank 201. In addition, the igniter 203 is installed on the inner wall of the storage tank 201. The left and right sides of the bottom of the storage tank 201 are provided with symmetrically distributed elastic telescopic members 204. Furthermore, the left and right sides of the waste discharge funnel 202 are provided with channels for the elastic telescopic members 204 to pass through, so as to avoid the waste discharge funnel 202 from interfering with the movement of the elastic telescopic members 204 when it sinks with the storage tank 201.

[0034] The elastic telescopic component 204 includes a positioning tube 2041, a piston rod 2042, and a first spring 2043. The positioning tube 2041 is fixedly installed on the inner wall of the furnace body 1, and the piston rod 2042 is movably inserted into the positioning tube 2041.

[0035] The piston rod 2042 is also equipped with a signal transmitter 205 at its top, while the signal receiver 206 is embedded in the inner wall of the furnace body 1. As the amount of fuel in the storage tank 201 changes, its counterweight changes continuously, causing the storage tank 201 to rise or sink in the furnace body 1. During this time, the signal transmitter 205 will pair with the upper and lower signal receivers 206 to produce and output different judgment information to the controller 7 to execute different control commands, namely, the command to feed or stop feeding.

[0036] The waste collection assembly 3 includes a waste collection box 301, a second spring 302, and a guide slide rod 303. The waste collection box 301 is equipped with the second spring 302 on the left and right sides, so that the waste collection box 301 can be connected to the furnace body 1 through the second spring 302. The guide slide rod 303 is fixedly connected to the top of the front and rear sides of the waste collection box 301. The guide slide rod 303 is horizontally slidably arranged in the slide groove on the side wall of the furnace body 1.

[0037] The fuel conveying assembly 4 includes a drive roller 401, a support frame 402, a conveyor belt 403, a material conveying trough 404, and a motor 405. The support frame 402 is installed on the side wall of the furnace body 1. The upper and lower support frames 402 are rotatably connected to the drive roller 401. The ends of the conveyor belt 403 are respectively connected to the drive roller 401. The lower support frame 402 is longer than the upper support frame 402, so that the conveyor belt 403 is in an inclined and raised state. The surface of the conveyor belt 403 is provided with a material conveying trough 404. The lower drive roller 401 is fixedly connected to the output shaft of the motor 405 through a coupling. The upper and lower drive rollers 401 are driven by the conveyor belt 403, so that the conveyor belt 403 can circulate and convey materials from bottom to top by means of the material conveying trough 404 on its surface, and unload at the conveying inflection point at the top of the conveyor belt 403.

[0038] The lifting transmission assembly 5 includes a turntable 501, a swing rod 502, a slide block 503, a receiving tube 504, and a connecting rod 505. The turntable 501 is fixedly sleeved on the end of the transmission roller 401, and a protruding rod is provided on the outer edge of the turntable 501. One end of the swing rod 502 is rotatably connected to the protruding rod, while the other end of the swing rod 502 is movably engaged with the slide block 503. The slide block 503 is slidably connected to a slide rail on the side wall of the furnace body 1. The bottom wall of the slide block 503 is equipped with a receiving tube 504 and a connecting rod 505 movably inserted into the receiving tube 504. The receiving tube 504 passes through a groove on the side wall of the storage trough 201 and is fixedly connected to the material distribution plate 8. Furthermore, the furnace... The side wall of the body 1 has a window for the connecting rod 505 to be raised and lowered. The transmission roller 401 can carry the turntable 501 to rotate coaxially. Then, when the protruding rod on the outer edge of the turntable 501 rotates around its wheel center, it can lift the swing rod 502 to swing left and right. The other end of the swing rod 502 pushes the slide 503 to move horizontally back and forth along the side wall of the furnace body 1, so that the slide 503 carries the retractable receiving tube 504 and the connecting rod 505 to move left and right as a whole. This allows the connecting rod 505 to slide horizontally back and forth in the inner cavity of the material storage tank 201 with the material distribution plate 8. On the one hand, this realizes the turning of material to avoid the problem of incomplete combustion caused by fuel accumulation, and on the other hand, it realizes automatic waste discharge.

[0039] The oscillation transmission assembly 6 includes a pusher 601, a pulley 602, a synchronous belt 603, a rotating shaft 604, and a bearing 605. The bearing 605 is fixedly connected to the outer wall of the furnace body 1. The pusher 601 is rotatably connected to the bearing 605 via the rotating shaft 604. Both the rotating shaft 604 and the transmission roller 401 are equipped with pulleys 602, and the pulleys 602 are connected by a synchronous belt 603. A push rod is fixedly connected to the pusher 601, and the transmission roller 401 can carry the pulleys 602. 02. The upper and lower pulleys 602 are driven by a synchronous belt 603, which makes the lower push block 601, pulley 602 and rotating shaft 604 rotate coaxially. During the rotation, the push rod on the outer edge of the push block 601 will intermittently push the guide slide rod 303, so that the waste collection box 301 connected to the guide slide rod 303 can oscillate back and forth in the furnace body 1 by means of the second spring 302, so as to flatten the waste slag received in the waste collection box 301 and improve the utilization rate of the recycling space.

[0040] In this embodiment, it should be specifically noted that the bottom wall of the storage tank 201 is provided with a sieve hole, and the residual waste residue can pass through the sieve hole and be introduced into the waste collection box 301 by the waste discharge funnel 202 for collection.

[0041] The material distribution plate 8 is horizontally slidably installed inside the furnace body 1. The upper and lower layers of the material distribution plate 8 are respectively equipped with a grid and a brush plate. The material distribution plate 8 slides horizontally back and forth in the storage tank 201. On the one hand, the fuel falling into the combustion component 2 can pass through the upper grid when the material distribution plate 8 moves, realizing material turning and avoiding the problem of incomplete combustion caused by fuel accumulation. On the other hand, the waste residue is continuously pushed by the lower brush plate of the material distribution plate 8 and discharged through the screen holes on the bottom wall of the storage tank 201.

[0042] The telescopic arrangement of the receiving tube 504 and the connecting rod 505 ensures that the slide block 503 does not interfere with the lifting and lowering motion of the storage tank 201 when it is pushed and pulled back and forth by the swing rod 502, so that the material distribution plate 8 can slide horizontally and stably in the inner cavity of the storage tank 201.

[0043] Working principle of this invention:

[0044] As the fuel stored in the storage tank 201 continues to burn, its counterweight gradually decreases, allowing the piston rod 2042 to push the storage tank 201 upward under the elastic force of the first spring 2043. This causes the storage tank 201 and the waste discharge funnel 202 to rise as a whole until the signal transmitter 205 mounted on the piston rod 2042 aligns with the upper signal receiver 206. At this time, the upper signal receiver 206 can receive the target signal emitted by the signal transmitter 205 and determine that the fuel in the storage tank 201 is insufficient and needs to be replenished. The upper signal receiver 206 then outputs the first target determination information to the controller 7. The controller 7 receives the first target determination information and outputs a control command to the motor 405 to drive the motor 405.

[0045] Next, the output shaft of motor 405 drives the transmission roller 401 connected to it to rotate via a coupling. The upper and lower transmission rollers 401 are connected by a conveyor belt 403, which allows the conveyor belt 403 to circulate materials from bottom to top via the material conveying trough 404 on its surface. The materials are unloaded at the conveying inflection point at the top of the conveyor belt 403, allowing fuel to be introduced into the storage trough 201 from the feeding chute on the side wall of the furnace body 1 for automatic feeding and fuel replenishment. At the same time, the transmission roller 401 carries the turntable 501 connected to its end to rotate coaxially. Then, the convex rod on the outer edge of the turntable 501 rotates around its wheel center, pulling the swing arm 502 to swing back and forth. This allows the other end of the swing arm 502 to push the slide block 503 to move horizontally back and forth along the slide rail on the side wall of the furnace body 1. Then, the slide block 503 carries the retractable receiving tube 504 and the connecting rod 505 to move left and right as a whole, allowing the connecting rod 505 to carry The material distribution plate 8 slides horizontally back and forth in the inner cavity of the storage tank 201. On the one hand, the fuel falling into the combustion component 2 can pass through the upper grid when the material distribution plate 8 moves, realizing material turning and avoiding the problem of incomplete combustion caused by fuel accumulation. On the other hand, the waste residue is continuously pushed by the brush plate under the material distribution plate 8 and discharged through the screen holes on the bottom wall of the storage tank 201. Then, it is introduced into the waste collection box 301 by the waste discharge funnel 202 for collection. At the same time, the transmission roller 401 also carries the pulley 602 connected to its end to rotate coaxially. The upper and lower pulleys 602 are driven by the synchronous belt 603, so that the push block 601, pulley 602 and rotating shaft 604 below rotate coaxially. The push rod on the outer edge of the push block 601 will intermittently push the guide slide rod 303 during the rotation, so that the waste collection box 301 connected to the guide slide rod 303 can oscillate back and forth in the furnace body 1 by the second spring 302, so as to flatten the waste residue received in the waste collection box 301 and improve the utilization rate of the recycling space.

[0046] As waste residue is continuously discharged from the storage tank 201 and new fuel is continuously added, the counterweight of the storage tank 201 increases. Consequently, the storage tank 201 will press down on the piston rod 2042 and compress the first spring 2043, causing the storage tank 201 and the waste discharge funnel 202 to sink downwards as a whole until the signal transmitter 205 mounted on the piston rod 2042 aligns with the lower signal receiver 206. At this time, the lower signal receiver 206 can receive the target signal emitted by the signal transmitter 205 and determine that there is enough fuel in the storage tank 201 and feeding should be stopped. Then, the lower signal receiver 206 outputs the second target judgment information to the controller 7. The controller 7 receives the second target judgment information and outputs a control command to the motor 405, controlling the motor 405 to stop driving, and the equipment continues to burn and supply energy.
