Description

Technical Field

[0001] The utility model relates to the technical field of radiant tubes, in particular to a ceramic radiant tube which is convenient for installation. Background Art

[0002] A gas radiant tube is a device that uses combustible gas to generate thermal radiation, mainly used for heating or heat treatment processes. It is a common heating device widely used in industrial and commercial fields. The basic working principle of a gas radiant tube is to generate high temperature by burning gas, thereby emitting thermal radiation to directly heat the target object. There is usually a combustion chamber inside the gas radiant tube, and heat is generated by burning natural gas, liquefied petroleum gas or other gases. The heat generated by the combustible gas is used to heat the inner surface of the radiant tube. The radiant tube is usually made of high-temperature resistant materials such as metal alloys or ceramics to withstand high temperatures. The surface of the heated radiant tube emits infrared radiation. The thermal radiation transfers heat to the surrounding through the outer surface of the radiant tube, directly heating the object without the need for air convection or heat conduction. The heated radiant tube transfers heat to the target object in the form of radiation, usually heating the object or the working area. This heating method can quickly and evenly heat the object, especially suitable for application scenarios that require efficient heating.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1-5 , an embodiment provided by the present invention: a ceramic radiant tube convenient for installation, including a ceramic radiant tube 2, a refractory component 1 is penetrated through the lower end of the ceramic radiant tube 2, connecting flanges 4 are fixedly arranged at both ends of the lower part of the ceramic radiant tube 2, insertion tubes 6 are fixedly arranged at the lower ends of the two connecting flanges 4, a plurality of threaded holes 7 are opened on the upper end surfaces of the two connecting flanges 4, and connecting plugs 5 are arranged inside the plurality of threaded holes 7;

[0035] The connecting plug 5 includes a threaded column 502, a screw head 501 is fixedly arranged at the upper end of the threaded column 502, clamping rods 503 are hinged on both sides of the lower end surface of the threaded column 502 through torsion springs, stoppers 504 are fixedly arranged at the lower ends of the two clamping rods 503, and an opening spring 505 is fixedly arranged between the two clamping rods 503;

[0036] When the present invention is in use, there is no need to install nuts at the lower part, and only by turning the threaded column 502 at the upper part can the installation between the two flanges be realized, with simple operation and convenient use.

[0037] The ceramic radiant tube 2 includes a ceramic tube body 201, a plurality of embedded grooves 207 are opened on the inner surface of the ceramic tube body 201, heat conduction holes 208 are opened inside the plurality of embedded grooves 207, heat conduction plates 206 are fixedly arranged inside the plurality of embedded grooves 207, the heat conduction plates 206 are used for heat conduction, heat conduction columns 203 are fixedly arranged at the centers of the sides of the plurality of heat conduction plates 206 close to the heat conduction holes 208, one ends of the plurality of heat conduction columns 203 penetrate through the heat conduction holes 208 and extend to the outside of the ceramic tube body 201, and heat dissipation jackets 204 are fixedly arranged, and the heat dissipation jackets 204 are used for heat dissipation.

[0038] The heat dissipation jacket 204 is fixedly sleeved on the outer surface of the ceramic tube body 201. The heat dissipation jacket 204, the heat conducting plate 206 and the heat conducting column 203 are all made of aluminum alloy material, which has strong heat conduction and dissipation capabilities. The outer surface of the heat dissipation jacket 204 is provided with a protective layer 205, which is made of epoxy resin coating. The epoxy resin coating has high chemical resistance and mechanical strength. The inner surface between the ceramic tube body 201 and the heat conducting plate 206 is coated with an insulating layer 202, which is made of polytetrafluoroethylene coating and has excellent electrical insulation performance, high temperature resistance performance, and strong chemical stability, and can maintain the insulation effect in a harsh environment. The threaded post 502 is threadedly sleeved inside the threaded hole 7, and the installation is convenient through the thread. Two support components 3 are fixedly arranged at the upper end of the ceramic radiant tube 2, and the support components 3 are used for supporting.

[0039] The ceramic radiant tube 2 adopts a unique connecting plug 5 design, and the plug includes a threaded post 502, a clamping rod 503, a stopper 504 and an opening spring 505. This design simplifies the installation process and does not require installing nuts at the lower part. During installation, the worker only needs to rotate the upper threaded post 502 to make it pass through the flange hole. Under the action of the torsion spring and the opening spring 505, the clamping rod 503 automatically clamps the outer edge of the flange to achieve a firm connection.

[0040] The installation of traditional radiant tubes usually requires installing nuts at the lower part, and this process may cause installation difficulties due to narrow space during actual operation, especially when the radiant tube is close to the ground or in a narrow area. Through the innovative design, this patent avoids this inconvenience and makes the installation process smoother. During the installation of the present utility model, only upper part operation is needed, and the connection between the flanges can be achieved by screwing the threaded post 502. The whole process does not require additional tools or special skills, greatly simplifies the installation steps, and reduces the installation time. Since complex operations are not required at the lower part, the installers can more flexibly select the installation position. Whether at a relatively high height or in a narrow space, the installation can be conveniently completed. This design reduces the parts required for installation, such as bolts and nuts commonly used in traditional designs. This not only reduces the manufacturing and maintenance costs, but also reduces the risk of failures during the installation process.

[0041] Working principle: During use, heat can be absorbed by the heat conduction plate 206 and the heat conduction column 203, and then dissipated by the heat dissipation jacket 204 to achieve the function of heat dissipation. In cooperation with the ceramic tube body 201 of the main body, the heat resistance and thermal stability are increased. During installation, the insertion tube 6 is inserted into another flange, and then the threaded column 502 is rotated so that the threaded column 502 passes through the flange hole of the other flange, making the stopper 504 exposed outside. During the process of passing through the flange hole, the opening spring 505 is compressed, and under the action of the torsion spring, the two latch rods 503 approach each other. After passing through, under the action of the torsion spring and the opening spring 505, the two latch rods 503 move away from each other to achieve the function of the stopper 504 clamping the periphery of the flange. Then, by rotating the threaded column 502 in the reverse direction, the two flanges are clamped, and there is no need to install nuts at the bottom, making the installation more convenient.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
