Description

Technical Field

[0001] This utility model relates to the field of tunnel furnace heating, and in particular to an energy-saving heating fan and a tunnel furnace. Background Technology

[0002] A tunnel furnace is a continuous heating device equipped with a hot air circulation system. Forced convection via a fan ensures uniform temperature within the furnace. However, current heating fans exhibit inefficient propagation paths, resulting in significant energy loss due to unutilized energy loss during these inefficient propagation paths. Utility Model Content

[0003] Therefore, it is necessary to provide an energy-saving heating fan and tunnel furnace to address the heating energy loss problem of tunnel furnaces.

[0004] This utility model provides an energy-saving heating fan, including a motor, fan blades, a heating component, and a flow guiding component. The drive head of the motor is fixedly connected to the fan blades, and the flow guiding component is arranged around the side of the fan blades. The heating component includes a heating pipe and a pipe fixing frame. The pipe fixing frame is arranged around the outside of the flow guiding component, and the heating pipe is fixedly installed on the pipe fixing frame. The pipe fixing frame has a hollow structure. When the motor drives the fan blades to rotate, the cold airflow enters from the front of the fan blades, is guided by the flow guiding component to the heating component, and carries away the heat generated by the heating pipe to become a hot airflow.

[0005] In some embodiments, the flow guiding assembly includes an upper fixing ring, a lower fixing plate, and a plurality of flow guiding plates. The two ends of the flow guiding plates are respectively fixedly connected to the upper fixing ring and the lower fixing plate to form an annular groove structure. The center of the lower fixing plate is fixedly connected to the drive head of the motor.

[0006] In some embodiments, the pipe fixing bracket includes an upper support plate, a lower support plate, and multiple fixing plates. The two ends of the fixing plates are fixedly connected to the upper support plate and the lower support plate, respectively, forming a hollow U-shaped structure. The fixing plates are provided with fixing notches adapted to the heating pipe, and the heating pipe is fixed to the fixing notches.

[0007] In some embodiments, the fixed notch is provided with a heat insulation ring adapted to the heating pipe.

[0008] In some embodiments, each of the fixing plates has at least two fixing notches, and the heating pipes are sequentially fixed to the notches on each of the fixing plates to form a multi-layered pipe loop with interconnected pipes.

[0009] In some embodiments, deformation notches are provided on both sides of the fixed notch.

[0010] In some embodiments, a hollow partition is also included, which is disposed between the motor and the fan blade, and the drive head of the motor passes through the hollow partition and is fixedly connected to the fan blade.

[0011] In some embodiments, the hollow partition has through holes on its side.

[0012] In some of these embodiments, the motor is equipped with a control box.

[0013] This utility model embodiment also provides a tunnel furnace, including the above-mentioned energy-saving heating fan.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This embodiment of the invention arranges the flow guiding component around the side of the fan blade and the pipe fixing bracket around the outside of the flow guiding component, so that the heating component is located at the tail end of the air inlet channel. When the motor drives the fan blade to rotate, the cold airflow enters from the front of the fan blade, is guided by the flow guiding component to the heating component, and carries away the heat generated by the heating pipe to become hot airflow. This eliminates the ineffective propagation path of the heating fan and improves energy utilization. In addition, the use of an annular flow channel tail end increases the hot air area and improves the heating efficiency of the tunnel furnace. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See Figure 1 This utility model provides an energy-saving heating fan, including a motor 1, fan blades, a heating component 2, and a flow guiding component 3. The drive head of the motor 1 is fixedly connected to the fan blades, and the flow guiding component 3 is arranged around the side of the fan blades. The heating component 2 includes a heating pipe 21 and a pipe fixing frame 22. The pipe fixing frame 22 is arranged around the outside of the flow guiding component 3, and the heating pipe 21 is fixedly installed on the pipe fixing frame 22. The pipe fixing frame 22 has a hollow structure. When the motor 1 drives the fan blades to rotate, the cold airflow enters from the front of the fan blades, is guided by the flow guiding component 3 to the heating component 2, and carries away the heat generated by the heating pipe 21 to become hot airflow.

[0024] In this embodiment, the fan blades have a conventional structure, so they are not shown for the purpose of demonstrating other structures. In this embodiment, cold airflow and hot airflow are relative concepts, rather than limitations on specific airflow temperatures. For example, of two airflows, the one with a higher airflow temperature is the hot airflow, and the one with a lower airflow temperature is the cold airflow.

[0025] In this embodiment, by arranging the airflow guide assembly 3 around the side of the fan blades and the heating pipe 21 around the outside of the airflow guide assembly 3, when the motor 1 drives the fan blades to rotate, the cold airflow enters from the front of the fan blades, is guided by the airflow guide assembly 3 to the heating assembly 2, and carries away the heat generated by the heating pipe 21, becoming hot airflow that directly enters the heating chamber of the heating equipment (such as a tunnel furnace). This shortens the ineffective propagation path of the hot airflow in traditional heating fans and more effectively improves energy utilization. The sequential surrounding design of the airflow guide assembly 3 and the heating assembly 2 increases the hot air area and effectively improves the heating efficiency of the heating equipment.

[0026] In some embodiments, such as Figure 2 As shown, the flow guiding assembly 3 includes an upper fixing ring 31, a lower fixing plate 32, and a plurality of flow guiding plates 33. The two ends of the flow guiding plates 33 are respectively fixedly connected to the upper fixing ring 31 and the lower fixing plate 32 to form an annular groove structure; the center of the lower fixing plate 32 is fixedly connected to the drive head of the motor 1.

[0027] In this embodiment, the annular groove structure is adapted to the fan blade, which is disposed within the annular groove structure and fixedly connected to the drive head of the motor. The lower fixing plate 32 is fixedly connected to the drive head of the motor 1, so that multiple guide vanes 33 rotate accordingly, accelerating the airflow to diffuse to the surrounding heating components 2 and improving the working efficiency of the heating fan.

[0028] In some embodiments, such as Figure 2 and Figure 3 As shown, the pipe fixing bracket 22 includes an upper support plate 221, a lower support plate 222 and a plurality of fixing plates 223. The two ends of the fixing plate 223 are respectively fixedly connected to the upper support plate 221 and the lower support plate 222 to form a hollow structure. The fixing plate 223 is provided with a fixing notch 2231 adapted to the heating pipe 21, and the heating pipe 21 is fixed to the fixing notch 2231.

[0029] In this embodiment, the fixing notch 2231 has an interference fit structure. For example, the fan-shaped area of ​​the fixing notch 2231 accounts for one-third of the total circular cross-sectional area of ​​the pipe, thereby improving the fixing effect on the heating pipe 21. At the same time, the sequential arrangement of the fixing plates 223 can make the airflow uniform and stable, improving the temperature uniformity and stability of the heating fan.

[0030] Optionally, the fixing notch 2231 is provided with a heat insulation ring 224 adapted to the heating pipe 21. The heat insulation ring 224 can reduce the heat conduction from the heating pipe to the fixing plate 223, thereby reducing heat conduction loss, and can prevent high temperature from damaging the fixing plate 223, thus protecting the fixing plate 223.

[0031] Optionally, each of the fixing plates 223 is provided with at least two fixing notches 2231, and the heating pipe 21 is fixed in sequence to the fixing notches 2231 on each of the fixing plates 223 to form a multi-layer pipe loop with pipe connection.

[0032] In this optional embodiment, at least two fixed notches 2231 are provided to facilitate the layout of the heating pipe 21, forming a multi-layer pipe loop, increasing the contact area between the airflow and the heating pipe, thereby better heating the airflow to form a hot airflow; and the multi-layer pipe loop avoids the use of a thick pipe to obstruct the airflow, thereby improving the stability and smoothness of the airflow.

[0033] Optionally, such as Figure 3 As shown, the fixing notch 2231 has deformation notches 2232 on both sides. By setting the deformation notches 2232, the two sides of the fixing notch 2231 can deform when the heating pipe 21 is installed, which improves the ease of installation of the heating pipe 21, and the heating pipe 21 can be fixed by relying on the rigidity of the material on both sides of the fixing notch 2231 to spring back.

[0034] In some embodiments, such as Figure 2 As shown, it also includes a hollow partition 4, which is disposed between the motor 1 and the fan blades. The drive head of the motor 1 passes through the hollow partition 4 and is fixedly connected to the fan blades. The hollow partition 4 can isolate the motor 1 from the heating component 2, preventing heat conduction from the heating component 2 from causing the motor 1 to overheat further and reduce its working efficiency. At the same time, the hollow partition 4 can hide the power supply lines of the motor 1 and the heating component 2, improving aesthetics.

[0035] In some embodiments, such as Figure 2 As shown, the hollow partition 4 has through holes 41 on its side to facilitate the release of heat from the hollow partition 4.

[0036] In some embodiments, such as Figure 4 As shown, the motor 1 is equipped with a control box 11 to facilitate the control operation of the motor 1 and the heating component 2.

[0037] This utility model embodiment also provides a tunnel furnace, including the above-mentioned energy-saving heating fan.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
