Description

Technical Field

[0001] This utility model relates to the field of furnace technology, and in particular to a blower for heat homogenization in furnaces. Background Technology

[0002] A furnace is a core thermal equipment used in industrial production for heating or melting materials at high temperatures. Its core function is to generate a high-temperature environment through fuel combustion or electrical energy conversion to achieve processes such as melting, smelting, and heat treatment of materials. It is widely used in fields such as metal smelting, casting, and heat treatment, for example, to melt iron ore into molten iron, remelt scrap steel into steel ingots, or to perform high-temperature homogenization and quenching on metal workpieces.

[0003] In existing technologies, furnace blowers typically use airflow channels to supply air into the furnace, ensuring that the combustion medium is fully mixed with air and improving combustion efficiency. However, the use of fixed airflow in the airflow channels can easily lead to uneven airflow inside the furnace, which not only affects the completeness of fuel combustion but also causes an imbalance in heat distribution, thereby reducing the furnace's thermal efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a blower for homogenizing furnace heating.

[0005] This utility model is achieved by the following technical solution: a blower for heating a furnace, including a furnace, a turbine blower is connected inside the furnace, an adjustment component is provided on the inner wall of the furnace, a quick-change component is provided on the inner wall of the furnace, and the quick-change component is located to the right of the adjustment component; The adjustment assembly includes a support plate, a motor fixedly connected to the top of the support plate, a rotating rod fixedly connected to the output end of the motor, a turntable fixedly connected to the end of the rotating rod away from the motor, a fixing rod fixedly connected to the outer wall of the turntable, a connecting plate rotatably connected to the outer wall of the fixing rod, a first fixing rod rotatably connected to the inner end of the connecting plate away from the fixing rod, an adjustment plate fixedly connected to the outer end of the first fixing rod, a support rod rotatably connected to the inner end of the adjustment plate away from the first fixing rod, and a first connecting plate rotatably connected to the outer wall of the first fixing rod.

[0006] As a further improvement to the above solution, the support plate is fixedly connected to the outer wall of the furnace, the rotating rod is rotatably connected to the inside of the furnace, and the support rod is fixedly connected to the inner wall of the furnace.

[0007] Through the above technical solution, the reciprocating swing of the first fixed rod will drive the adjusting plate to swing left and right around the support rod as the axis. The first connecting plate drives several adjusting plates to swing synchronously, ultimately achieving the left and right guidance of the airflow sent into the furnace by the turbine fan. The airflow can more evenly cover the surface of the combustion medium, avoiding incomplete combustion of the medium due to lack of air in some areas. At the same time, it reduces the heat loss caused by excess air in some areas, allowing the energy of the fuel and other combustion media to be fully released, reducing energy consumption and improving thermal efficiency.

[0008] As a further improvement to the above solution, the quick-change component includes a heat exchange component, which is fixedly connected to the inner wall of the furnace. A baffle is fixedly connected to the inner wall of the furnace, and a sliding groove is provided inside the furnace.

[0009] Through the above technical solutions, the heat exchange components can recover waste heat from the furnace to preheat fresh air, reduce the impact of high-temperature airflow on subsequent components, improve the overall heat utilization efficiency, and the baffles provide guidance and protection for the filter plates.

[0010] As a further improvement to the above solution, a sliding plate is slidably connected to the outer wall of the chute, and a spring is fixedly connected to the outer wall of the sliding plate.

[0011] As a further improvement to the above solution, the end of the spring away from the sliding plate is fixedly connected to the inner wall of the slide groove, and a connecting rod is fixedly connected to the outer wall of the sliding plate.

[0012] As a further improvement to the above solution, a push plate is fixedly connected to the end of the connecting rod away from the sliding plate, and a pin is fixedly connected to the outer wall of the push plate.

[0013] As a further improvement to the above solution, the pin is slidably connected inside the furnace, a filter plate is slidably connected to the outer wall of the pin, and the filter plate is slidably connected to the inner wall of the furnace.

[0014] By using the above technical solution, the pin rod can be disengaged from the filter plate, allowing the filter plate to be pulled out from the inner wall of the furnace for replacement. No special tools or disassembly of other parts are required, and the operation can be carried out by a single person, which greatly shortens maintenance downtime and reduces the impact on production schedule.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a motor fixed to the top of a support plate. The motor drives a rotating rod to rotate, which in turn drives a turntable to rotate synchronously. A fixed rod on the outer wall of the turntable moves in a circular motion with the turntable. Through a connecting plate, the first fixed rod is driven to swing back and forth. An adjusting plate is connected to the connecting plate through the first fixed rod, and the other end of the adjusting plate is rotatably connected to the inner wall of the furnace through a support rod. The reciprocating swing of the first fixed rod drives the adjusting plate to swing left and right around the support rod as an axis. The first connecting plate drives several adjusting plates to swing synchronously, ultimately guiding the airflow sent into the furnace by the turbine fan to the left and right. The airflow can more evenly cover the surface of the combustion medium, avoiding incomplete combustion due to insufficient air in some areas, while reducing heat loss caused by excess air in some areas. This allows the energy of the fuel and other combustion media to be fully released, reducing energy consumption and improving thermal efficiency.

[0016] This invention allows personnel to push a push plate, which in turn drives a sliding plate to slide within a groove via a connecting rod. The sliding plate compresses a spring, and simultaneously, the push plate drives a pin to slide within the furnace, causing the pin to disengage from the filter plate. This allows the filter plate to be pulled out from the inner wall of the furnace for replacement without the need for specialized tools or disassembly of other components. It can be operated by a single person, significantly reducing maintenance downtime and minimizing the impact on production schedules. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example: Please combine Figure 1-6 This embodiment provides a blower for heating a furnace, including a furnace 1, a turbine blower 2 connected inside the furnace 1, an adjustment component 3 on the inner wall of the furnace 1, and a quick-change component 4 on the inner wall of the furnace 1, with the quick-change component 4 located to the right of the adjustment component 3. The adjustment assembly 3 includes a support plate 301, a motor 302 fixedly connected to the top of the support plate 301, a rotating rod 303 fixedly connected to the output end of the motor 302, a turntable 304 fixedly connected to the end of the rotating rod 303 away from the motor 302, a fixing rod 305 fixedly connected to the outer wall of the turntable 304, a connecting plate 306 rotatably connected to the outer wall of the fixing rod 305, a first fixing rod 307 rotatably connected to the inner end of the connecting plate 306 away from the fixing rod 305, an adjustment plate 308 fixedly connected to the outer end of the first fixing rod 307, a support rod 309 rotatably connected to the inner end of the adjustment plate 308 away from the first fixing rod 307, and a first connecting plate 310 rotatably connected to the outer wall of the first fixing rod 307.

[0021] The support plate 301 is fixedly connected to the outer wall of the furnace 1, the rotating rod 303 is rotatably connected to the inside of the furnace 1, and the support rod 309 is fixedly connected to the inner wall of the furnace 1.

[0022] When the motor 302 starts, it drives the rotating rod 303 to rotate, which in turn drives the turntable 304 to rotate synchronously. The fixed rod 305 on the outer wall of the turntable 304 moves in a circular motion with the turntable 304. Through the transmission of the connecting plate 306, it drives the first fixed rod 307 to swing back and forth. Since the adjusting plate 308 is connected to the connecting plate 306 through the first fixed rod 307, and the other end of the adjusting plate 308 is rotatably connected to the inner wall of the furnace 1 through the support rod 309, the reciprocating swing of the first fixed rod 307 will drive the adjusting plate 308 to swing left and right around the support rod 309 as the axis. At the same time, the first connecting plate 310 drives several adjusting plates 308 to swing synchronously. Finally, it realizes the left and right guidance of the airflow sent into the furnace 1 by the turbine fan 2, changes the airflow direction, and the airflow can more evenly cover the surface of the combustion medium, avoid incomplete combustion of the medium due to lack of air in some areas, and reduce the heat loss caused by excess air in some areas. This allows the energy of the fuel and other combustion media to be fully released, reduces energy consumption, and improves thermal efficiency.

[0023] The quick-change assembly 4 includes a heat exchange assembly 401, which is fixedly connected to the inner wall of the furnace 1. A baffle 402 is fixedly connected to the inner wall of the furnace 1, and a sliding groove 403 is provided inside the furnace 1.

[0024] A sliding plate 404 is slidably connected to the outer wall of the slide groove 403, and a spring 405 is fixedly connected to the outer wall of the sliding plate 404.

[0025] The end of the spring 405 away from the sliding plate 404 is fixedly connected to the inner wall of the slide groove 403, and the outer wall of the sliding plate 404 is fixedly connected to the connecting rod 406.

[0026] A push plate 407 is fixedly connected to the end of the connecting rod 406 away from the sliding plate 404, and a pin 408 is fixedly connected to the outer wall of the push plate 407.

[0027] The pin 408 is slidably connected inside the furnace 1, and the outer wall of the pin 408 is slidably connected to the filter plate 409, which is slidably connected to the inner wall of the furnace 1.

[0028] The push plate 407 drives the sliding plate 404 to slide in the slide groove 403 via the connecting rod 406. The sliding plate 404 compresses the spring 405. At the same time, the push plate 407 drives the pin 408 to slide in the furnace 1, so that the pin 408 disengages from the filter plate 409. The filter plate 409 can then be pulled out from the inner wall of the furnace 1 for replacement without the need for special tools or disassembly of other parts. It can be operated by a single person, which greatly shortens maintenance downtime and reduces the impact on production schedule.

[0029] The implementation principle of a blower for furnace homogenization in this embodiment is as follows: Motor 302 is fixed to the top of support plate 301. When motor 302 starts, it drives rotating rod 303 to rotate. Rotating rod 303 then drives turntable 304 to rotate synchronously. Fixed rod 305 on the outer wall of turntable 304 moves in a circular motion with turntable 304. Through transmission via connecting plate 306, it drives first fixed rod 307 to reciprocate. Since adjusting plate 308 is connected to connecting plate 306 via first fixed rod 307, and the other end of adjusting plate 308 is supported... Rod 309 is rotatably connected to the inner wall of furnace 1. Therefore, the reciprocating swing of the first fixed rod 307 drives the adjusting plate 308 to swing left and right around the support rod 309 as the axis. At the same time, the first connecting plate 310 drives several adjusting plates 308 to swing synchronously. Ultimately, this achieves the left and right guidance of the airflow sent into furnace 1 by the turbine fan 2, changing the airflow direction so that the airflow can more evenly cover the surface of the combustion medium, avoiding incomplete combustion due to lack of air in some areas, and reducing heat loss caused by excess air in some areas, allowing the energy of fuel and other combustion media to be fully released. To reduce energy consumption and improve thermal efficiency, the heat exchange component 401 is fixed to the inner wall of the furnace 1. The heat exchange component 401 can recover waste heat from the furnace to preheat fresh air, reducing the impact of high-temperature airflow on subsequent components and improving overall thermal utilization efficiency. The baffle 402 guides and protects the filter plate 409. When the filter plate 409 needs to be replaced, the push plate 407 is pushed. The push plate 407 drives the sliding plate 404 to slide in the slide groove 403 through the connecting rod 406. The sliding plate 404 compresses the spring 405, and at the same time, the push plate 407 drives the pin 4. 08 slides inside furnace 1, causing pin 408 to disengage from filter plate 409, allowing filter plate 409 to be pulled out from the inner wall of furnace 1 for replacement. No special tools or disassembly of other parts are required; single-person operation is possible, significantly reducing maintenance downtime and minimizing impact on production schedule. After replacement, release push plate 407, and spring 405 resets, pushing sliding plate 404 to slide in the opposite direction. Through connecting rod 406, push plate 407 and pin 408 reset, and pin 408 re-engages into filter plate 409, thus securing filter plate 409.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
