[0001] This utility model relates to the field of burner technology, specifically a burner for heating a rotary kiln. Background Technology

[0002] Rotary kiln burners are the core heating equipment in rotary kiln systems in industries such as cement, metallurgy, and chemicals. They generate high-temperature flames through the efficient mixing and combustion of fuel and combustion air, providing a stable heat source for the calcination of materials.

[0003] Currently, the gas pipe and nozzle in the burner are connected by flanges and bolts. The sealing performance of the flange connection depends heavily on the uniformity of the bolt preload, the condition of the gasket, and the installation accuracy. In addition, there are usually six bolt holes on the flange. The entire installation process requires repeated alignment of the bolt holes between the two flanges, making the assembly operation difficult and time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a burner for heating rotary kilns, which solves the problems of difficult and time-consuming connection between the gas pipe and the nozzle in current burners.

[0005] This utility model discloses a burner for heating a rotary kiln, comprising a gas pipe, a nozzle, a hollow column, a locking column, and a nozzle. A positioning ring is fixedly connected to the inside of the gas pipe near one end. A through hole is annularly formed on the surface of the gas pipe near the positioning ring. An air duct is connected to the surface of the gas pipe. The nozzle is movably inserted into the inside of the gas pipe near one end of the positioning ring. An installation groove is formed on the surface of the nozzle corresponding to the through hole. A first sleeve is fixedly connected inside the installation groove. A second sleeve is fixedly connected to the center of the bottom of the inner wall of the first sleeve. The hollow column passes through the through hole and is detachably inserted into the inside of the first sleeve. The locking column passes through the inside of the hollow column and is detachably inserted into the inside of the second sleeve. The nozzle is fixedly connected to the end of the nozzle away from the gas pipe. An igniter is fixedly connected to the end of the nozzle near the nozzle.

[0006] As a further improvement of this utility model, a first handle is fixedly connected to the upper end of the outer surface of the hollow column, and a first threaded protrusion is integrally formed on the lower end of the outer surface of the hollow column. The inner wall of the through hole and the inner wall of the first sleeve are both provided with a first threaded groove that matches the first threaded protrusion. The hollow column is sequentially threadedly connected to the through hole and the first sleeve.

[0007] As a further improvement of this utility model, a fixing ring is fixedly connected to the center inside the hollow column, and a second threaded protrusion is integrally formed on the outer surface of the locking column. The inner wall of the fixing ring and the interior of the second sleeve are both provided with the second threaded protrusion, and the locking column is sequentially threadedly connected to the fixing ring and the second sleeve.

[0008] As a further improvement of this utility model, a limiting ring is fixedly connected to the inner wall of the hollow column near the top, and a limiting plate is fixedly connected to the center of the upper surface of the locking column, the diameter of the limiting plate being larger than the inner diameter of the limiting ring.

[0009] As a further improvement of this utility model, the top of the limiting plate is detachably fixed with a tightening structure. The tightening structure includes a second handle, and a connecting rod is fixedly connected to the center of the bottom of the second handle. The connecting rod is movably inserted into the middle of the limiting plate. A countersunk hole is opened in the middle of the second handle, and a screw is provided in the countersunk hole. The screw passes through the inside of the connecting rod and is threaded into the inside of the locking post.

[0010] As a further improvement of this utility model, a plug is fixedly connected to the side of the positioning ring away from the center of the gas pipe, and a plug hole is opened at the end of the nozzle away from the nozzle and at the position corresponding to the plug hole, and the plug is movably inserted into the plug hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a hollow column that passes through a through hole and is threadedly connected to a first sleeve. A first handle on the outside of the hollow column allows for quick tightening, securing the connection between the gas pipe and the nozzle. A locking column passes through the hollow column and is threadedly connected to a second sleeve. Simultaneously, the locking column is threadedly connected to a fixing ring within the hollow column, locking and securing the hollow column and preventing accidental rotation, thus ensuring the stability of the connection. A positioning ring at the end of the gas pipe engages with a socket at the end of the nozzle, enabling rapid alignment of the plug and socket. This ensures that each through hole aligns perfectly with the first sleeve, eliminating the complexity of multi-hole alignment in traditional connection processes and significantly reducing installation time.

[0022] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0023] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] Please see Figure 1-5This utility model discloses a rotary kiln heating burner, comprising a gas pipe 1, a nozzle 3, a hollow column 7, a locking column 11, and a nozzle 4. A positioning ring 6 is fixedly connected inside the gas pipe 1 near one end. A through hole 101 is annularly formed on the surface of the gas pipe 1 near the positioning ring 6. An air duct 2 connects to the surface of the gas pipe 1. The nozzle 3 is movably inserted into the gas pipe 1 near one end of the positioning ring 6. An installation groove is formed on the surface of the nozzle 3 corresponding to the through hole 101. A first sleeve 16 is fixedly connected inside the installation groove. The bottom of the inner wall of the first sleeve 16... The center of the part is fixedly connected to the second sleeve 17. The hollow column 7 passes through the through hole 101 and is detachably inserted into the inside of the first sleeve 16. The locking column 11 passes through the inside of the hollow column 7 and is detachably inserted into the inside of the second sleeve 17. The nozzle 4 is fixedly connected to the end of the nozzle 3 away from the gas pipe 1. The end of the nozzle 3 near the nozzle 4 is fixedly connected to the igniter 5. The positioning ring 6 is fixedly connected to the side away from the center of the gas pipe 1 with the insertion block 601. The end of the nozzle 3 away from the nozzle 4 and the position corresponding to the insertion block 601 are provided with an insertion hole. The insertion block 601 is movably inserted into the insertion hole.

[0025] In this embodiment, a first handle 8 is fixedly connected to the upper end of the outer surface of the hollow column 7, and a first threaded protrusion is integrally formed on the lower end of the outer surface of the hollow column 7. The inner wall of the through hole 101 and the inner wall of the first sleeve 16 are both provided with a first threaded groove that matches the first threaded protrusion. The hollow column 7 is sequentially threadedly connected to the through hole 101 and the first sleeve 16.

[0026] Through the above technical solution, the hollow column 7 can be threadedly connected to both the through hole 101 and the first sleeve 16 at the same time, thereby tightly connecting the gas pipe 1 and the nozzle 3 together, replacing the connection operation of practical flange and bolt alignment, and greatly reducing the time required for installation.

[0027] To prevent the hollow column 7 from loosening accidentally, in this embodiment, a fixing ring 10 is fixedly connected to the center inside the hollow column 7, and a second threaded protrusion is integrally formed on the outer surface of the locking column 11. The inner wall of the fixing ring 10 and the interior of the second sleeve 17 are both provided with the second threaded protrusion. The locking column 11 is sequentially threadedly connected to the fixing ring 10 and the second sleeve 17.

[0028] Through the above technical solution, after the workers thread the locking pin 11 to the second sleeve 17 and the fixing ring 10, the hollow pin 7 can be fixed to prevent it from loosening.

[0029] In some other embodiments, the locking rotation direction of the hollow column 7 is opposite to that of the locking column 11, which can prevent them from rotating simultaneously when subjected to external force in the same direction.

[0030] In this embodiment, a limiting ring 9 is fixedly connected to the inner wall of the hollow column 7 near the top, and a limiting plate 12 is fixedly connected to the center of the upper surface of the locking column 11. The diameter of the limiting plate 12 is larger than the inner diameter of the limiting ring 9. By setting the limiting plate 12 and the limiting ring 9, the locking column 11 can be prevented from falling out of the hollow column 7, thus preventing the loss of parts.

[0031] In this embodiment, a tightening structure is detachably fixed to the top of the limiting plate 12. The tightening structure includes a second handle 13. A connecting rod 14 is fixedly connected to the center of the bottom of the second handle 13. The connecting rod 14 is movably inserted into the middle of the limiting plate 12. A countersunk hole is opened in the middle of the second handle 13. A screw 15 is provided in the countersunk hole. The screw 15 passes through the interior of the connecting rod 14 and is threaded into the interior of the locking post 11.

[0032] The above technical solution makes it convenient for staff to tighten or loosen the locking pin 11 from the outside.

[0033] like Figure 1 As shown, when connecting the gas pipe 1 and the nozzle 3, the worker directly inserts the right end of the nozzle 3 into the left side of the gas pipe 1, so that the insert block 601 is inserted into the corresponding insertion hole. At this time, each through hole 101 corresponds to each mounting slot. The worker can hold the first handle 8, insert the hollow column 7 into the through hole 101 and rotate it until the hollow column 7 is screwed into the inside of the first sleeve 16. Then, the worker holds the second handle 13 and rotates it to screw the locking column 11 into the inside of the fixing ring 10 and the second sleeve 17 to lock the hollow column 7.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
