Description

Technical Field

[0001] This utility model belongs to the field of burner brick technology, specifically relating to a burner with a tightened opening. Background Technology

[0002] A burner, also known as a combustion nozzle, is a common name for a combustion device used in industrial fuel furnaces. It can be understood as an abbreviation for "fire nozzle". It usually refers to the main body of the combustion device, which has a fuel inlet, an air inlet and an outlet. It plays the role of distributing fuel and combustion air and spraying them out in a certain way for combustion. It is a common structure in furnaces nowadays, which helps the combustion device to operate stably.

[0003] Current burner bricks rely primarily on the grooves inside the brick to eject flames. However, this presents certain problems in actual use. Specifically, the grooves inside the existing burner bricks are tubular structures with uniform opening diameters at both the top and bottom. This structure results in short flames, low temperatures on the front wall of the furnace, and high temperatures on the rear wall, leading to uneven temperatures within the furnace and affecting the performance of the combustion device.

[0019] To make the above-mentioned objectives, 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.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0022] Depend on Figure 1 As shown, it is a structural schematic diagram of the burner with a tightening opening in this embodiment. The burner includes a mating end 1, a connecting seat 2, and a spray nozzle 3. The connecting seat 2 is installed on the side of the mating end 1. The mating end 1 and the connecting seat 2 form a complete burner brick body. The burner brick body has a spray nozzle 3 for spraying flame. The connecting seat 2 has an installation screw 4 installed on its side for easy overall installation.

[0023] When in use, the burner brick body is placed in the target position of the furnace by using the installation screw 4. Then, by using the injection slot 3, the passing gas is first contracted and then expanded and sprayed out, which can spray the flame into the front wall in a broom shape, so that the temperature inside the furnace is uniform and the heat utilization rate is optimal.

[0024] From the appendix Figure 2 As shown, this is a schematic diagram of the spray slot 3 in this embodiment. The spray slot 3 includes a contraction port 31, a horizontal flow port 32, and a spray port 33. The contraction port 31 is provided inside the burner brick body. The horizontal flow port 32 is provided inside the burner brick body on the side of the contraction port 31 and is connected to the contraction port 31. The spray port 33 is installed on the side of the burner brick body and is connected to the horizontal flow port 32. The overall length of the horizontal flow port 32 is 3cm. Both the contraction port 31 and the spray port 33 are conical slots, and the maximum inner diameter of the contraction port 31 is smaller than the maximum inner diameter of the spray port 33.

[0025] During use, the structure and shape of the contraction port 31 are used to contract the incoming gas. The gas then converges and passes through the horizontal flow port 32. The structure of the injection port 33 is then used to amplify and eject the flame caused by the gas. The flame is sprayed onto the front wall in a broom shape, achieving stable flame ejection while controlling the internal temperature of the furnace.

[0026] From the appendix Figure 3 and Figure 4 The diagram shown is a structural schematic of the sealing mechanism 5 in this embodiment. The sealing mechanism 5 includes a mounting base 51, a sealing element 52, a sealing plate 53, and a plug-in block 54. The connecting base 2 has symmetrically arranged mounting grooves on its side, in which the mounting base 51 is installed. The sealing element 52 is installed outside the mounting base 51. The sealing plate 53 is installed on the side of the mating end 1, and a compression groove for pressing against the sealing element 52 is formed within the sealing plate 53. The sealing element 52 consists of a threaded rod and a nut. A threaded rod is installed on the side of the mounting base 51, and a nut is installed on the external thread of the threaded rod. The width of the compression groove is greater than the diameter of the threaded rod. A plug-in block 54 is installed on the side of the mating end 1, and a plug-in groove for insertion into the connecting base 2 is formed.

[0027] During use, the connecting seat 2 and the mating end 1 are brought together so that the plug block 54 is inserted into the plug groove. Then, by using the mounting seat 51, the threaded rod enters the extrusion groove. The nut is rotated along the external thread of the threaded rod to achieve a stable fit between the connecting seat 2 and the mating end 1, thus achieving a stable connection of the burner brick body. This facilitates quick replacement and adjustment of any damaged parts of the burner brick body, ensuring the stability of the burner brick body during use.
