Description

Technical Field

[0001] This utility model belongs to the field of kiln technology, and in particular relates to an adjustable kiln gas burner. Background Technology

[0002] A kiln gas burner is a core thermal device installed on various industrial kilns (such as ceramic kilns, metallurgical kilns, refractory material kilns, etc.) and uses natural gas, liquefied petroleum gas, coal gas (such as blast furnace gas, coke oven gas) as energy. Through a specific structural design, it achieves precise mixing and stable combustion of fuel and air, and efficiently transfers heat to the kiln cavity.

[0003] In kiln heating operations, the axial position of all the gas burners we currently use is fixed, which makes it difficult to adapt to different kiln cavity depths, material placements, and process requirements. The fixed length can easily lead to imbalances in the heating area, causing local overheating or underheating and reducing energy efficiency. Therefore, it is necessary to design an adjustable kiln gas burner that can adjust the axial length of the burner into the kiln as needed, flexibly matching different cavity depths, material layouts, and process sections, avoiding the limitations of fixed length adaptation, eliminating local overheating or underheating caused by improper insertion, and improving product quality stability. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable kiln gas burner that can flexibly match different inner cavity depths, material layouts and process sections, avoid the limitations of fixed length adaptation, and eliminate the advantages of local overheating and underheating caused by improper insertion, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable kiln gas burner includes a fixed plate fixedly connected to the right side of the kiln by bolts. A rotatable threaded barrel is provided through the inner cavity of the fixed plate. A left retaining tooth is fixedly connected to the right side of the fixed plate. A sliding sleeve is slidably connected to the surface of the threaded barrel. A right retaining tooth is provided on the surface of the sliding sleeve. The right retaining tooth engages with the left retaining tooth. A threaded sleeve is threadedly connected to the surface of the threaded barrel. One side of the threaded sleeve is tightly fitted with the side of the right retaining tooth away from the left retaining tooth. A fixed sleeve is fixedly connected to the surface of the threaded sleeve. A gas burner is provided on the side of the threaded barrel away from the kiln. The burner end of the gas burner extends through the inner cavity of the threaded barrel.

[0006] Preferably, the surface of the sliding sleeve is provided with multiple sliding grooves, and the inner cavity of the right retaining tooth is fixedly connected with multiple convex sliders, which are slidably connected to the inner wall of the sliding sleeve.

[0007] Preferably, the surface of the fixing sleeve is fixedly connected with multiple throttles.

[0008] Preferably, a connecting plate is fixedly connected to the right side of the fixed plate by bolts, and the side of the connecting plate away from the threaded barrel is fixedly connected to the gas burner.

[0009] Preferably, both the fixing plate and the connecting plate have circular grooves on their surfaces for bolts to pass through.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model fixes the fixed plate to one side of the kiln with bolts, adjusts the appropriate length by rotating the threaded barrel, and fixes the threaded barrel inside the fixed plate by the cooperation of the left and right locking teeth and the threaded sleeve. Finally, the gas burner is installed on one side of the connecting plate with bolts. This achieves flexible matching of different inner cavity depths, material layouts and process sections, avoids the limitation of fixed length adaptation, and eliminates the purpose of local overheating and underheating caused by improper insertion.

[0012] 2. This utility model uses the cooperation of sliding groove and convex slider. When the right locking tooth slides on the surface of the sliding sleeve, the sliding groove guides the convex slider, ensuring that the position of the right locking tooth will not shift when it slides on the surface of the sliding sleeve, thus improving the stability of the convex slider when it engages with the left locking tooth.

[0013] 3. By setting up a throttle, this utility model applies force to the fixed sleeve when it needs to be rotated on the surface of the threaded barrel, which facilitates the adjustment of the fixed sleeve. Attached Figure Description

[0021] In the following description, embodiments of the adjustable kiln gas burner of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an adjustable kiln gas burner according to an embodiment of the present invention. It includes a fixed plate 2 bolted to the right side of a kiln 1. A rotatable threaded barrel 3 is permeated through the inner cavity of the fixed plate 2. A left retaining tooth 4 is fixedly connected to the right side of the fixed plate 2. A sliding sleeve 5 is slidably connected to the surface of the threaded barrel 3. A right retaining tooth 7 is provided on the surface of the sliding sleeve 5, engaging with the left retaining tooth 4. Multiple sliding grooves 6 are formed on the surface of the sliding sleeve 5. Multiple convex sliders 8 are fixedly connected to the inner cavity of the right retaining tooth 7, slidably connected to the inner wall of the sliding sleeve 5. Through the cooperation of the sliding grooves 6 and the convex sliders 8, when the right retaining tooth 7 slides on the surface of the sliding sleeve 5, the sliding grooves 6 guide the convex sliders 8, ensuring that the position of the right retaining tooth 7 does not shift when sliding on the surface of the sliding sleeve 5, thus improving the engagement and connection of the convex sliders 8 with the left retaining tooth 4. To ensure stability, a threaded sleeve 9 is threadedly connected to the surface of the threaded barrel 3. One side of the threaded sleeve 9 is tightly fitted to the side of the right retaining tooth 7 away from the left retaining tooth 4. A fixing sleeve 10 is fixedly connected to the surface of the threaded sleeve 9. Multiple handles 11 are fixedly connected to the surface of the fixing sleeve 10. By setting the handles 11, when it is necessary to rotate the fixing sleeve 10 on the surface of the threaded barrel 3, the handles 11 apply force to the fixing sleeve 10 when it rotates, which facilitates the adjustment of the fixing sleeve 10. A gas burner 13 is set on the side of the threaded barrel 3 away from the kiln 1. The burner end of the gas burner 13 penetrates into the inner cavity of the threaded barrel 3. A connecting plate 12 is fixedly connected to the right side of the fixing plate 2 by bolts. The side of the connecting plate 12 away from the threaded barrel 3 is fixedly connected to the gas burner 13. The surfaces of the fixing plate 2 and the connecting plate 12 are both provided with circular grooves for bolts to pass through.

[0023] Working principle: When using this utility model, firstly, the fixing plate 2 is fastened to the preset installation position on the right side of the kiln 1 with bolts to ensure that the fixing plate 2 fits tightly against the kiln wall. Then, according to the depth of the kiln cavity, the material placement position, and the requirements of the current process section, the threaded barrel 3 is manually rotated to move axially within the cavity of the fixing plate 2 until the preset insertion length of the gas burner 13 meets the heating requirements. Next, the right locking tooth 7 is pushed, causing it to slide directionally within the sliding groove 6 of the sliding sleeve 5 via the convex slider 8, until the right locking tooth 7 is fully engaged with the left locking tooth 4 on the right side of the fixing plate 2, achieving the initial positioning of the threaded barrel 3. Next, hold the throttle 11 and rotate the fixing sleeve 10 to drive the threaded sleeve 9 to screw into the threaded surface of the threaded barrel 3, so that one side of the threaded sleeve 9 tightly presses against the side of the right retaining tooth 7 away from the left retaining tooth 4, locking the right retaining tooth 7 and the left retaining tooth 4, thus completing the axial position fixation of the threaded barrel 3. Then, insert the burner end of the gas burner 13 into the inner cavity of the threaded barrel 3, and then fasten the connecting plate 12 to the right side of the fixing plate 2 with bolts. Use the circular grooves on the surfaces of the connecting plate 12 and the fixing plate 2 for the bolts to pass through, ensuring that the gas burner 13 is firmly connected to the connecting plate 12 and the fixing plate 2. After adjustment, if there is no looseness, it can be put into use.

[0024] In summary, this adjustable kiln gas burner, by fixing the fixed plate 2 to one side of the kiln 1 with bolts, adjusting the appropriate length by rotating the threaded barrel 3, and using the cooperation of the left locking tooth 4, right locking tooth 7 and threaded sleeve 9 to fix the threaded barrel 3 in the inner cavity of the fixed plate 2, and finally installing the gas burner 13 on one side of the connecting plate 12 with bolts, can flexibly match different inner cavity depths, material layouts and process sections, avoid the limitation of fixed length adaptation, and eliminate the purpose of local overheating and underheating caused by improper insertion.
