Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a rotary flame tube. Background Art

[0002] An important indicator for measuring a burner is whether the combustion is sufficient and whether the combustion efficiency is high enough. The working principle of a burner is to introduce combustible gas and combustion-supporting gas into the burner in a certain proportion, ignite them after mixing in the burner, form a flame and then mix and burn again in the flame tube (or "combustion tube"), and finally eject them from the flame tube. The flame tube in the prior art is a simple straight tube, and the part of the combustible gas and combustion-supporting gas ejected from the burner cannot be fully mixed in the flame tube, which not only affects the combustion efficiency of the burner, but also causes a waste of combustible gas. In view of the above technical problems, the present application proposes a new technical solution to improve the structure of the flame tube, so as to improve the mixing degree of the combustible gas and the combustion-supporting gas entering the flame tube, thereby facilitating improving the combustion efficiency of the burner.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a rotating flame tube, aiming to solve the technical problem in the prior art that the degree of mixing of combustible gas and supporting gas in the flame tube is low, thereby affecting the combustion efficiency of the burner.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rotary flame tube comprises a tube body, the inner wall of which is provided with a plurality of spiral guide plates.

[0007] Furthermore, in the rotating flame tube, the inner cavity of the tube includes a first circular hole, a conical hole, and a second circular hole which are connected in sequence; the first circular hole is connected to the inlet end of the tube, and the second circular hole is connected to the outlet end of the tube; and the spiral guide plate is arranged on the inner wall of the second circular hole.

[0008] Furthermore, in the rotating flame tube, the diameter of the inlet end of the tapered hole is equal to the diameter of the first circular hole.

[0009] Furthermore, in the rotating flame tube, the diameter of the outlet end of the tapered hole is smaller than the diameter of the second circular hole.

[0010] Furthermore, in the rotary flame tube, the specifications of each spiral guide plate are the same.

[0011] Furthermore, in the rotary flame tube, all spiral guide plates are arranged at the same intervals in the circumferential direction.

[0012] Beneficial effect: The utility model provides a rotating flame tube. Compared with the prior art, the utility model arranges a plurality of spiral guide plates in the cylinder body of the flame tube so that the airflow in the flame tube is spirally ejected. In the process of spiral ejection, the combustible gas and the combustion-supporting gas can be further mixed, thereby improving the combustion efficiency and avoiding the waste of the combustible gas.

[0017] The utility model provides a rotating flame tube. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1-4 , the utility model provides a rotating flame tube. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual products. The accompanying drawings only show the structures related to the invention point of this application, and some conventional structures are not specifically drawn. The terms "first", "second", etc. described in this article are merely different names for similar structures for the convenience of explanation, and are not intended to limit this application. For the sake of convenience, this article inevitably uses some directional words, but these directional words are not intended to limit this application, because they can be set to different directions in actual applications. The "multiple" (or "several") mentioned in this article refers to an indefinite number, because the number of structures referred to is not an invention point, so it is not specifically limited.

[0019] The rotary flame tube includes a cylinder 1, which is different from the prior art in that a plurality of spiral guide plates 3 are provided on the inner wall of the cylinder. The specific parameters of the spiral guide plates are not limited here, because they can be determined according to actual production conditions. In actual applications, a mounting plate 2 is also provided at the inlet end of the cylinder, and the mounting plate is used to connect the cylinder and the burner (not shown in the figure).

[0020] The significance of arranging several spiral guide plates inside the cylinder of the flame tube is that when the burning flame ejects out of the flame tube, the spiral guide plates will change the flame ejection direction (i.e. the flame ejects in a spiral manner). During the spiral ejection process, the incompletely mixed natural gas and combustion-supporting gas mixed in the flame will be mixed and burned again, thereby improving the combustion efficiency and avoiding the waste of combustible gas.

[0021] Furthermore, the inner cavity of the cylinder includes a first circular hole 101, a tapered hole 102, and a second circular hole (not numbered in the figure) which are connected in sequence; the first circular hole is connected to the inlet end of the cylinder, and the second circular hole is connected to the outlet end of the cylinder; the spiral guide plate is arranged on the inner wall of the second circular hole (that is, the spiral guide plate is close to the outlet end of the flame tube).

[0022] Furthermore, the diameter of the inlet end of the tapered hole is equal to the diameter of the first circular hole.

[0023] Furthermore, the diameter of the outlet end of the tapered hole is smaller than the diameter of the second circular hole. This arrangement allows the second circular hole to have enough space to arrange the spiral guide plate.

[0024] The diameter of the outlet end of the tapered hole is larger than that of the inlet end, and the speed of the combustible gas and the combustion-supporting gas entering the second circular hole is reduced, thereby extending the time of the combustible gas and the combustion-supporting gas in the flame tube and improving the degree of mixing.

[0025] Preferably, each spiral guide plate has the same specifications, that is, parameters such as size and rotation direction are the same.

[0026] Preferably, all the spiral guide plates are arranged at the same intervals in the circumferential direction of the cylinder, so that the combustible gas and the combustion-supporting gas can be mixed to the same extent in all directions of the circumference.

[0027] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
