Description

Technical Field

[0001] The utility model relates to the technical field of fuel nozzles for incinerators, and particularly relates to a fuel nozzle structure for an incinerator. Background Art

[0002] The nozzle is one of the most important components in combustion equipment. Liquid fuel combustion generally uses a nozzle, and the quality of nozzle design has a great impact on the combustion of liquid fuel. The function of the nozzle is to atomize the liquid fuel to form a very small diameter liquid mist, so as to increase the contact area between the liquid fuel and the surrounding medium and achieve the purpose of rapid evaporation, mixing and combustion.

[0003] However, it still has some disadvantages. For example, the fuel nozzle of the incinerator mainly consists of a fuel nozzle head, a fuel nozzle body and a gasket. The existing gasket is a flat circular ring structure. When the fuel nozzle is compressed, due to the flat structure of the gasket, its resilience is small. When the fuel nozzle head and the fuel nozzle body are separated, the gasket cannot generate enough resilience, and there are gaps in the contact surfaces with the fuel nozzle head and the fuel nozzle body, that is, it cannot maintain sufficient pressing force, which is likely to cause the fuel nozzle head to become unthreaded and the fuel nozzle to leak oil.

[0004] To solve the above problems, a fuel nozzle structure for an incinerator is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fuel nozzle structure for an incinerator to solve the problems such as the fuel nozzle head becoming unthreaded and the fuel nozzle leaking oil in the prior art as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fuel nozzle structure for an incinerator, including a nozzle body, one end outer surface of the nozzle body is fixedly connected with a threaded connecting pipe, the other end outer surface of the nozzle body is fixedly connected with a nozzle head, and the upper end outer wall of the nozzle body is fixedly connected with an anti-leakage component.

[0007] Preferably, the anti-leakage component includes a connecting pipe, a sleeve, a piston block, a push rod, a spring, a circular block, a through hole one, a positioning block, a through hole two, a limiting sleeve and a ball. The connecting pipe is fixedly connected to the upper end outer wall of the nozzle body, and one end outer surface of the connecting pipe is fixedly connected with a sleeve.

[0008] Preferably, the inner cavity of the sleeve is movably connected with a piston block, the lower end outer surface of the piston block is fixedly connected with a push rod, and a spring is sleeved on the outer wall of the push rod, and both the push rod and the spring are located in the inner cavity of the sleeve.

[0009] Preferably, one end of the outer surface of the lower end of the push rod is fixedly connected with a circular block, and the circular block is located in the inner cavity of the nozzle body. A through hole one is opened in the middle of the outer surface of one side of the circular block.

[0010] Preferably, a positioning block is fixedly connected in the inner cavity of the nozzle body. A through hole two is opened in the middle of the outer surface of the positioning block.

[0011] Preferably, a limiting sleeve is fixedly connected to the inner wall of the through hole one, and a ball is movably connected to the inner wall of the limiting sleeve.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the leakage prevention component provided in the present utility model, when the nozzle body sprays oil outward, when the oil is sprayed outward, a certain pressure will be generated. Under the action of the pressure, the piston block and the push rod in the inner cavity of the sleeve will move downward, so that the through hole one on the circular block at the lower end of the push rod is communicated with the through hole two on the positioning block, and the oil is sprayed onto the nozzle head. When spraying is not required, the inner cavity of the sleeve will not feel the pressure brought by the oil. Under the action of the spring, the push rod will drive the circular block to move upward to block the through hole two. Therefore, it is convenient for us to effectively prevent oil leakage and other situations from occurring on the nozzle head after spraying during fuel spraying, reduce fuel loss during spraying, save resources, and the provided limiting sleeve and balls can facilitate us to spray the sprayed oil more evenly.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a fuel nozzle structure for an incinerator, including a nozzle body 1, a threaded connection pipe 2 is fixedly connected to the outer surface of one end of the nozzle body 1, a nozzle head 3 is fixedly connected to the outer surface of the other end of the nozzle body 1, and an anti-leakage component 4 is fixedly connected to the outer wall of the upper end of the nozzle body 1. Its overall structure is a copper structure with strong corrosion resistance.

[0021] In this embodiment, as Figures 2-4 shown, the anti-leakage component 4 includes a connection pipe 5, a sleeve 6, a piston block 7, a push rod 8, a spring 9, a circular block 10, a through hole one 11, a positioning block 12, a through hole two 13, a limiting sleeve 14 and a ball 15. The connection pipe 5 is fixedly connected to the outer wall of the upper end of the nozzle body 1. A sleeve 6 is fixedly connected to the outer surface of one end of the connection pipe 5. By providing the connection pipe 5, it is convenient for us to transport the oil in the nozzle body 1 into the sleeve 6, so that the piston block in the sleeve 6 generates a certain pressure. The inner cavity of the sleeve 6 is movably connected with a piston block 7. A push rod 8 is fixedly connected to the outer surface of the lower end of the piston block 7. A spring 9 is sleeved on the outer wall of the push rod 8, and both the push rod 8 and the spring 9 are located in the inner cavity of the sleeve 6. By providing the piston block 7, under the push of the piston block 7, the push rod 8 can be made more stable, and it is convenient for us to clamp the spring 9 in the sleeve 6. A circular block 10 is fixedly connected to the outer surface of one end of the lower end of the push rod 8, and the circular block 10 is located in the inner cavity of the nozzle body 1. A through hole one 11 is opened on the outer surface of the middle part of one side of the circular block 10. By providing the circular block 10 and the through hole one 11, it is convenient for us to block or open the through hole two 13. A positioning block 12 is fixedly connected to the inner cavity of the nozzle body 1. A through hole two 13 is opened on the outer surface of the middle part of the positioning block 12.

A ball 15 is movably connected to the inner wall of the limiting sleeve 14. By providing the ball 15, when the oil passes through the through hole one and the through hole two 10, a part of the pressure can be effectively relieved.

[0022] Working principle:

[0023] A fuel nozzle structure for an incinerator. When the nozzle body 1 is in use, first, through the leakage prevention component 4 provided, when the nozzle body 1 sprays oil outward, a certain pressure will be generated when the oil is sprayed outward. Under the action of the pressure, the piston block 7 and the push rod 8 in the inner cavity of the sleeve 6 will move downward, so that the through hole 11 on the circular block 10 at the lower end of the push rod 8 is connected to the through hole 13 on the positioning block 12 in a communicating manner, and the oil is sprayed onto the nozzle head 3. When spraying is not required, the inner cavity of the sleeve 6 will not feel the pressure brought by the oil. Under the action of the spring 9, the push rod 8 will drive the circular block 10 to move upward to block the through hole 13. Thus, it is convenient for us to effectively prevent oil leakage and other situations from occurring on the nozzle head 3 after spraying during fuel spraying, reduce fuel loss during spraying, save resources, and the provided limit sleeve 14 and the ball 15 can facilitate us to spray the sprayed oil more evenly.
