Technical Field
[0001] The utility model belongs to the technical field of heating equipment, and in particular relates to a radiant heating device. Background Art
[0002] A burner, also known as a burner, is a device widely used in industrial and civilian fields. Its main function is to inject and mix fuel and air in a specific way to achieve an efficient combustion process, thereby increasing heat output.
[0003] However, there is a significant problem during the operation of the burner, that is, during the movement of the burner, the heat on the outer wall of the radiation tube will inevitably dissipate into the surrounding environment, which will lead to heat loss in vain. When heat is lost, in order to achieve the predetermined temperature or power output, the burner needs to use more fuel during operation to meet the predetermined temperature or power output requirements. The whole process not only increases the energy effect, but also increases the operating cost.
[0004] Therefore, how to reduce heat loss and improve the thermal efficiency of the burner has become an urgent problem to be solved. Summary of the Invention
[0005] In order to solve the above technical problems, the utility model proposes a radiant heating device.

[0009] Support plates are provided on both sides of the first support frame, and the support plates are located below the radiation tube to support the radiation tube; the ends of the support plates are connected to the reflector to support the reflector;
[0010] The reflector is arranged above the radiation tube and has a bilaterally symmetrical "bow" cross-section. The inner wall of the reflector is used to reflect infrared rays, and the final reflected emission end of the inner wall of the reflector faces downward. The design of the radiation tube, the first support frame, and the reflector effectively supports and fixes the radiation tube. The first fixed space formed by the two symmetrical first arc-shaped support rods and the connecting bolt of the first support frame can firmly fix the radiation tube to prevent it from unnecessary movement during operation. At the same time, the provision of the reflector can effectively reduce heat loss and improve thermal efficiency, which not only enhances the stability of the entire device but also helps to improve heat utilization.
[0011] Preferably, the reflective cover is composed of two side wing covers that are symmetrically distributed on the left and right, and the side wing covers include a plurality of reflective plates that are distributed at intervals. Infrared rays with the same incident angle are reflected by the plurality of reflective plates and then emitted in parallel.
[0012] The reflective cover is composed of two side covers symmetrically distributed on the left and right. Each side cover includes several reflective plates distributed at intervals, so that infrared rays with the same incident angle are reflected by several reflective plates and emitted in parallel, thereby achieving uniform distribution and efficient utilization of heat. The design of this reflective cover further improves the thermal efficiency and use effect of the heating device.
[0013] Preferably, the lateral length of the reflector is no less than the axial length of the radiant tube, and the bottom of the reflector contacts the end of the support plate. This ensures that the reflector completely covers the radiant tube, minimizing heat loss and improving thermal efficiency. It also enhances the overall stability of the device.
[0014] Preferably, the tops of the two first arc-shaped support rods are each provided with a first hook;
[0015] The connecting bolt includes a connecting rod and sleeve rings and tilting handles located at both ends of the connecting rod;

[0018] Preferably, the first support frame includes two symmetrically arranged lifting lugs, an auxiliary lifting lug, and a V-shaped plate disposed between the lifting lugs and the first arc-shaped support rod, wherein the ends of the auxiliary lifting lugs are respectively connected to the lifting lugs. The design of the auxiliary lifting lugs and the V-shaped plate improves the stability and transportation efficiency of the first support frame. The ends of the auxiliary lifting lugs are respectively connected to the lifting lugs, further improving the stability of the first support frame during transportation. The provision of the V-shaped plate enables the first support frame to better adapt to different installation environments, thereby improving the flexibility and adaptability of the device.

This allows the second support frame to provide more stable support, thereby improving the overall stability and durability of the device.
[0023] Compared with the prior art, the present invention has the following advantages and effects:
[0024] 1. The design of the first support frame and support plate effectively improves the stability of the radiant tube during operation. The first fixed space formed by the two first curved support rods and the connecting bolt of the first support frame can firmly fix the radiant tube and prevent it from moving unnecessarily during operation. At the same time, the middle part of the support plate supports the radiant tube, and the end part supports the reflector. This design not only enhances the stability of the entire device, but also helps to improve heat utilization.
[0025] 2. The design of the reflector can effectively reduce heat loss.

This allows the heat on the outer wall of the radiant tube to be reflected back to the inner side of the reflector, thereby reducing the dissipation of heat to the surrounding environment and improving thermal efficiency. The symmetrical design of the reflector ensures uniform distribution of heat in the space. After multiple reflections inside the reflector, the infrared rays are emitted in a parallel manner, which means that the heat can cover the irradiation area more evenly, improving the uniformity and comfort of heating.
[0026] 3. The design of the lifting lugs and auxiliary lifting lugs of the first support frame facilitates transportation and installation. The design of the lifting lugs and auxiliary lifting lugs makes the first support frame easy to hang and transport, improving the stability during transportation.

DETAILED DESCRIPTION
[0036] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in conjunction with specific implementation methods.
[0037] Example 1:
[0038] like Figures 1 to 4 As shown, the present invention provides a radiant heating device, comprising a radiant tube 1, a first support frame and a reflector 30;
[0039] The first support frame is provided with two symmetrical first arc-shaped support rods 21, a connecting bolt is provided between the two first arc-shaped support rods 21, the two first arc-shaped support rods 21 and the connecting bolt form a first fixed space, and the radiation tube 1 is located in the first fixed space;
[0040] Support plates 4 are provided on both sides of the first support frame. The support plates 4 are located below the radiation tube 1 to support the radiation tube 1. The ends of the support plates 4 are connected to the reflector 30 to support the reflector 30.
[0041] The reflector 30 is positioned above the radiant tube 1 and has a bilaterally symmetrical "bow" cross-section. Its inner wall reflects infrared radiation, with the final reflected emission end (the infrared ray reflection emission end) facing downward. The radiant tube 1, the first support frame, and the reflector 30 effectively support and secure the radiant tube 1. The first support frame's two symmetrical first curved support rods 21 and connecting bolts 201 create a first securing space that securely holds the radiant tube 1. Furthermore, the reflector 30 effectively reduces heat loss, improves thermal efficiency, and contributes to increased heat utilization.
[0042] The reflector 30 is composed of two symmetrically distributed side wing covers, each of which includes a number of reflective plates spaced apart. Infrared rays with the same incident angle relative to the incident angle of the reflector plates are reflected by the reflective plates and then emitted in parallel. The reflector 30 is composed of two symmetrically distributed side wing covers, each of which includes a number of reflective plates spaced apart. Infrared rays with the same incident angle are reflected by the reflective plates and then emitted in parallel, thereby achieving uniform distribution and efficient utilization of heat. The angles between the reflective plates adjacent to the side wing covers are 159°, 156°, 157°, and 158°, respectively. After being refracted by the reflective plates, the infrared rays will no longer be reflected back onto the radiant tube 1, but will eventually be radiated to the heating area.
[0043] The lateral length of the reflector 30 is no less than the axial length of the radiant tube 1, and the bottom of the reflector 30 contacts the end of the support plate 4. This ensures that the reflector 30 completely covers the radiant tube 1, thereby minimizing heat loss and improving thermal efficiency. It also enhances the overall stability of the device.
[0044] The tops of the two first arc-shaped support rods 21 are each provided with a first hook 211;
[0045] The connecting bolt includes a connecting rod 201 and sleeve rings 202 and a tilting handle 23 located at both ends of the connecting rod 201;
[0046] The tilting direction of the tilting handle 23 is toward the upper side of the connecting rod 201;
[0047] The sleeve ring 202 is sleeved with the curved portion of one first hook 211, and the outer wall of the tilting handle 23 contacts the curved portion of the other first hook 211. This facilitates the installation and removal of the connecting bolt and improves the stability and transportation efficiency of the first support frame.
[0048] The first support frame includes two symmetrically arranged lifting ears 204, an auxiliary lifting ear 200, and a V-shaped plate 203 arranged between the lifting ears 204 and the first arc-shaped support rod 21. The two ends of the auxiliary lifting ear 200 are respectively connected to the lifting ears 204. This improves the stability and transportation efficiency of the first support frame.
[0049] The included angle of the V-shaped plate 203 is 45° to 60°, so that the first support frame can provide more stable support.
[0050] The middle portion of the support plate 4 is configured as an arcuate surface, and the ends of the support plate 4 are configured as inclined surfaces. The arcuate surface contacts the outer wall of the radiant tube 1, and the inclined surface contacts the bottom of the reflector 30. This allows the support plate 4 to better contact the radiant tube 1 and the reflector 30, thereby improving the stability and thermal efficiency of the device.
[0051] Working Principle: The radiation tube 1 is auxiliaryly fixed by the two first curved support rods 21 of the first support frame. The connecting bolt and the two first curved support rods 21 form a first fixing space to fix the radiation tube 1. The end of the support plate 4 supports the reflector 3, so that the heat on the outer wall of the radiation tube 1 is reflected back to the inner side of the reflector 3. This solves the technical problem in the prior art that heat will inevitably dissipate into the surrounding environment, improves the utilization rate of heat, avoids the need for more fuel to reach the predetermined temperature or power output during the operation of the burner, and saves operating costs.
[0052] The design of the sleeve ring 202 and the tilting handle 23 facilitates the installation and removal of the connecting bolt, and facilitates the turnover and transportation of the connecting bolt 20. The two lifting ears 204 of the first support frame facilitate the hanging of the first support frame, and then facilitate the transportation of the first support frame through the existing turnover device. The auxiliary lifting ears 200 are hung on the existing turnover device, which can further improve the stability of the hanging and transportation of the first support frame. The design of the support plate 4, the first support frame, and the connecting bolt not only solves the technical problem in the prior art that heat will inevitably dissipate into the surrounding environment, but also facilitates the installation and fixation of the radiation tube 1 and the reflector 3, thereby improving the work efficiency during installation.
[0053] Example 2:
[0054] For Example 2 of the present utility model, Figure 5 、 Figure 6 Note that, descriptions of parts that are the same as those in Example 1 are omitted and are given the same reference numerals.
[0055] like Figure 5 、 Figure 6 As shown, the radiant heating device of the present invention further includes two symmetrical second support frames, each of which is provided with two symmetrical second hooks 50. The two second hooks 50 are respectively hooked at the two ends of the curved surface. The second support frames and the curved surface form a second fixed space, and the radiant tube 1 is located in the second fixed space. This further improves the fixation of the radiant tube and enhances the stability of the entire device.
[0056] The second support frame includes a second arc-shaped support rod 52 and support rods 51 located at both ends of the second arc-shaped support rod 52 . One end of the support rod 51 away from the second arc-shaped support rod 52 is connected to the second hook 50 .
[0057] The second curved support rod 52 of the second support frame forms a second fixed space with the curved surface, further improving the fixation of the radiant tube 1. When the radiant tube 1 is in operation, it generates vibrations, thereby enhancing the stability of the entire device. The second support frame includes the second curved support rod 52 and support rods 51 at both ends of the second curved support rod. This design enables the second support frame to provide more stable support, improving the overall stability and durability of the device.
[0058] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
