Description

Technical Field

[0001] This utility model relates to the technical field of kiln tail exhaust fans, and specifically discloses an energy-saving kiln tail exhaust fan. Background Technology

[0002] In industrial production, kilns, as important thermal equipment, are widely used in industries such as ceramics, building materials, and metallurgy. The kiln tail exhaust fan, as a key component of the kiln system, primarily functions to promptly remove high-temperature flue gas, dust, and other waste generated at the kiln tail, ensuring stable internal air pressure and maintaining normal production environment and process conditions.

[0003] However, traditional kiln tail exhaust fans present numerous problems in practical use. Firstly, the airflow adjustment of existing fans is often imprecise and complex to operate, making it difficult to flexibly adjust according to the exhaust requirements of different kiln conditions. When the kiln load changes, untimely or inaccurate airflow adjustment can easily lead to energy waste, contradicting the modern industrial development concept of energy conservation and emission reduction. Secondly, the kiln tail exhaust air temperature is high and contains a large amount of corrosive gases and dust, which can cause severe wear and corrosion to components such as the fan blades, shortening the equipment's lifespan and increasing the frequency of maintenance and replacement. This not only affects production efficiency but also further increases operating costs. Therefore, an energy-saving kiln tail exhaust fan is needed to solve these problems. Utility Model Content

[0004] This utility model proposes an energy-saving kiln tail exhaust fan. By rotating the threaded rod to drive the operation of related components, the fan blade angle can be changed to adjust the air volume. It can flexibly adapt to different working conditions, effectively reduce energy consumption, and achieve the effect of energy saving and consumption reduction.

[0005] This utility model is implemented as follows: an energy-saving kiln tail exhaust fan includes a kiln body, and the kiln body is provided with an air volume regulating mechanism.

[0006] The airflow regulating mechanism includes a frame. Multiple rotating shafts are rotatably connected to the outer wall of the frame via bearings. Fan blades are fixedly connected to the outer walls of the multiple rotating shafts located outside the frame. Gears are fixedly connected to the outer walls of the multiple rotating shafts located inside the frame. Racks are meshed to the outer walls of the multiple gears. A drive plate is fixedly connected to the outer walls of the multiple racks. A horizontal plate is fixedly connected to the outer wall of the frame. A threaded rod is threadedly connected to the outer wall of the horizontal plate. The other end of the threaded rod is rotatably connected to the drive plate via bearings.

[0007] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, an installation rod is fixedly connected to the inner wall of the kiln body, a motor is installed on the outer wall of the installation rod, and the output end of the motor passes through the installation rod and is fixedly connected to the frame.

[0008] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, a support plate is threadedly connected to the outer wall of the kiln body, and a filter screen is threadedly connected through the outer wall of the support plate.

[0009] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, the outer wall of the drive plate is fixedly connected with two limiting rods, one end of each limiting rod passing through the horizontal plate and slidably connected to the horizontal plate.

[0010] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, a scale strip is fixedly connected to the outer wall of the drive plate, and a pointer that cooperates with the scale strip is fixedly connected to the outer wall of the frame.

[0011] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, the outer wall of the fan blades is coated with a high-temperature resistant and corrosion-resistant coating.

[0012] As a preferred embodiment of the energy-saving kiln tail exhaust fan of this utility model, a cross knob is installed on the outer wall of the threaded rod.

[0013] The beneficial effects of this utility model are:

[0014] To adjust the airflow, the operator simply rotates the cross knob on the threaded rod. The threaded rod is threadedly connected to the horizontal plate and rotates in conjunction with the drive plate. Rotation causes the drive plate to move horizontally, while a limit rod slides within the horizontal plate to ensure stable movement. The drive plate's movement synchronously moves the rack, which meshes with the gear to rotate, thereby rotating the fan blades and changing their angle via a rotating shaft. A scale and pointer allow the operator to visually monitor the fan blade angle, achieving precise airflow control. In summary, this exhaust fan is easy to operate, allows for precise airflow adjustment to adapt to different working conditions, and effectively removes smoke while achieving energy savings.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 An energy-saving kiln tail exhaust fan includes a kiln body 1, and an air volume regulating mechanism is installed inside the kiln body 1.

[0023] The airflow regulating mechanism includes a frame 5. Multiple rotating shafts 6 are rotatably connected to the outer wall of the frame 5 through bearings. Fan blades 12 are fixedly connected to the outer walls of the multiple rotating shafts 6 located outside the frame 5. Gears 7 are fixedly connected to the outer walls of the multiple rotating shafts 6 located inside the frame 5. Racks 8 are meshed with the outer walls of the multiple gears 7. A drive plate 9 is fixedly connected to the outer walls of the multiple racks 8. A horizontal plate 10 is fixedly connected to the outer wall of the frame 5. A threaded rod 11 is threadedly connected to the outer wall of the horizontal plate 10 through it. The other end of the threaded rod 11 is rotatably connected to the drive plate 9 through bearings.

[0024] In this embodiment: when it is necessary to adjust the air volume according to the kiln operating conditions, the operator can do so by rotating the cross knob on the outer wall of the threaded rod 11. Since the threaded rod 11 is threadedly connected to the horizontal plate 10, and the other end of the threaded rod 11 is rotatably connected to the drive plate 9 through a bearing, rotating the threaded rod 11 will cause the drive plate 9 to move in the horizontal direction. At this time, the two limiting rods 13 fixed on the outer wall of the drive plate 9 slide within the horizontal plate 10, which limits and guides the movement of the drive plate 9, ensuring its stable movement.

[0025] When the drive plate 9 moves, it drives multiple racks 8 fixedly connected to it to move synchronously. The racks 8 mesh with the gears 7 inside the rotating shaft 6. The movement of the racks 8 drives the gears 7 to rotate, which in turn drives the fan blades 12 to rotate through the rotating shaft 6, thus changing the angle of the fan blades 12. At the same time, the scale bar on the drive plate 9 works in conjunction with the pointer on the outer wall of the frame 5. The operator can intuitively grasp the adjustment angle of the fan blades 12 by pointing the pointer to the scale bar, thus achieving precise control of the air volume. Through the orderly cooperation of the above components, this energy-saving kiln tail exhaust fan can not only efficiently complete the smoke exhaust work, but also flexibly adjust the air volume according to actual needs, achieving the purpose of energy saving and consumption reduction.

[0026] As a technical optimization of this utility model, an installation rod 3 is fixedly connected to the inner wall of the kiln body 1, and a motor 4 is installed on the outer wall of the installation rod 3. The output end of the motor 4 passes through the installation rod 3 and is fixedly connected to the frame 5.

[0027] In this embodiment, the output end of the motor 4 is directly fixedly connected to the frame 5, which can efficiently transmit the power generated by the motor 4 to the frame 5, drive the frame 5 and the connected components such as the rotating shaft 6 and the fan blade 12 to rotate synchronously, thereby realizing the core function of the fan blade 12 rotating to generate airflow to discharge the waste at the kiln tail.

[0028] As a technical optimization of this utility model, the outer wall of the kiln body 1 is threadedly connected to a support plate 2, and the outer wall of the support plate 2 is threadedly connected to a filter screen.

[0029] In this embodiment, the filter screen installed on the outer wall of the kiln body 1 via the support plate 2 will filter the dust in the flue gas before it enters the exhaust fan, reducing the wear of dust on components such as the fan blade 12.

[0030] As a technical optimization of this utility model, two limiting rods 13 are fixedly connected to the outer wall of the drive plate 9. One end of each limiting rod 13 passes through the horizontal plate 10 and is slidably connected to the horizontal plate 10.

[0031] In this embodiment, the two limiting rods 13 fixed to the outer wall of the drive plate 9 slide within the horizontal plate 10, which limit and guide the movement of the drive plate 9, ensuring its stable movement.

[0032] As a technical optimization of this utility model, a scale strip is fixedly connected to the outer wall of the drive plate 9, and a pointer that cooperates with the scale strip is fixedly connected to the outer wall of the frame 5.

[0033] In this embodiment, the scale bar on the drive plate 9 and the pointer on the outer wall of the frame 5 work together. The operator can intuitively grasp the adjustment angle of the fan blade 12 by pointing the pointer to the scale bar, so as to achieve precise control of the air volume.

[0034] As a technical optimization of this utility model, the outer wall of the fan blade 12 is coated with a high-temperature resistant and corrosion-resistant coating.

[0035] In this embodiment, the high-temperature resistant and corrosion-resistant coating on the outer wall of the fan blade 12 can resist the corrosion of high-temperature flue gas, extend the service life of the fan blade 12, and ensure the long-term stable operation of the exhaust fan.

[0036] As a technical optimization of this utility model, a cross knob is installed on the outer wall of the threaded rod 11.

[0037] In this embodiment, the threaded rod 11 can be easily driven to rotate via the cross knob.

[0038] The working principle and usage process of this utility model are as follows: When the exhaust fan is started, the motor 4 installed on the mounting rod 3 begins to work. The output end of the motor 4 drives the frame 5 to rotate, and the frame 5 drives the outer fan blades 12 to rotate synchronously through the rotating shaft 6. The rotation of the fan blades 12 generates airflow, which discharges the high-temperature flue gas, dust and other waste from the tail of the kiln through the kiln body 1, thereby ensuring the stability of the air pressure inside the kiln.

[0039] When it is necessary to adjust the air volume according to the kiln operating conditions, the operator can do so by rotating the cross knob on the outer wall of the threaded rod 11. Since the threaded rod 11 is threadedly connected to the horizontal plate 10, and the other end of the threaded rod 11 is rotatably connected to the drive plate 9 through a bearing, rotating the threaded rod 11 will cause the drive plate 9 to move horizontally. At this time, the two limiting rods 13 fixed on the outer wall of the drive plate 9 slide within the horizontal plate 10, which limits and guides the movement of the drive plate 9, ensuring its stable movement.

[0040] When the drive plate 9 moves, it drives multiple racks 8 fixedly connected to it to move synchronously. The racks 8 mesh with the gears 7 inside the rotating shaft 6. The movement of the racks 8 drives the gears 7 to rotate, which in turn drives the fan blades 12 to rotate through the rotating shaft 6, thereby changing the angle of the fan blades 12. At the same time, the scale bar on the drive plate 9 works in conjunction with the pointer on the outer wall of the frame 5. The operator can intuitively grasp the adjustment angle of the fan blades 12 by pointing the pointer to the scale bar, thus achieving precise control of the airflow.

[0041] In addition, the filter screen installed on the outer wall of the kiln body 1 via the support plate 2 will filter the dust in the flue gas before it enters the exhaust fan, reducing the wear of dust on components such as the fan blade 12; while the high-temperature resistant and anti-corrosion coating on the outer wall of the fan blade 12 can resist the corrosion of high-temperature flue gas, extend the service life of the fan blade 12, and ensure the long-term stable operation of the exhaust fan.
