[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] like Figure 1-Figure 3 As shown, in one embodiment, a cleaning nozzle comprises: a device body 1, which is arranged in a powder conveying pipeline. A rotating nozzle 3 and a telescopic rod 2 are arranged inside the device body 1, and the rotating nozzle 3 is extended and retracted by controlling the movement of the telescopic rod 2.

[0028] Furthermore, the device body 1 includes a barrel, a cavity and a cylinder 7, and the two ends of the cavity are respectively connected to the barrel and the cylinder 7. Specifically, a clamp 15 is provided at the connection between the cavity and the cylinder 7, and a sealing gasket 14 is provided inside the clamp 15.

[0029] like Figure 1-Figure 3 As shown, in this embodiment, a driving chamber is provided inside the cylinder body 7, and air flow channels 101 are provided on both sides of the driving chamber for driving the telescopic rod 2 to extend and retract.

[0030] The air flow channel 101 is connected to the external air source 21 through the air pipe joint 17, and the specific air intake sequence is operated through the air intake control valve. Specifically, the air flow channel 101 includes a first channel 1011 and a second channel 1012. The first channel 1011 is used to control the telescopic rod 2 to drive the rotating nozzle 3 to retract, and the second channel 1012 is used to control the telescopic rod 2 to drive the rotating nozzle 3 to extend.

[0031] like Figure 1-Figure 3As shown, in this embodiment, the rotating nozzle 3 is arranged inside the barrel, and the telescopic rod 2 is arranged inside the cavity. The two ends of the telescopic rod 2 extend into the barrel and the cylinder 7 respectively. Specifically, an inclined spray hole 31 is opened on one side of the rotating nozzle 3, and a flow equalizing ring 4 is arranged in the middle of the rotating nozzle 3. When the cleaning liquid is sprayed out, it will drive the rotating nozzle 3 to rotate continuously, and the cleaning liquid will be sprayed evenly around, which effectively improves the cleaning effect.

[0032] Furthermore, a first retaining ring 12 is arranged between the tail of the rotating nozzle 3 and the head of the telescopic rod 2, which can limit the specific displacement stroke; a first sealing ring 10 is respectively arranged on the periphery of the tail of the rotating nozzle 3 and the head of the telescopic rod 2, a sealing ring 11 is arranged on the periphery of the tail of the telescopic rod 2, a third sealing ring 6 is arranged between the sealing ring 11 and the telescopic rod 2, and the sealing ring and the sealing ring 11 cooperate with each other to effectively improve the sealing performance of the device; a buffer ring 16 is arranged on one side of the sealing ring 11, and a second retaining ring 13 is arranged on one side of the buffer ring 16 to ensure that the telescopic rod 2 will not damage the inner wall of the barrel and the cylinder body 7 when extending and retracting the telescopic rod 2 forward and backward.

[0033] Furthermore, a first valve plate 5 is provided in the middle of the telescopic rod 2 , second valve plates 8 are provided on both sides of the first valve plate 5 , and a second sealing ring 9 is provided between the second valve plate 8 and the telescopic rod 2 .

[0034] Specifically, the first valve plate 5 and the second valve plate 8 divide the driving chamber inside the cylinder body 7 into two parts. The front driving chamber is connected to the first channel 1011. When the air source 21 supplies air, the telescopic rod 2 moves backward to drive the rotating nozzle 3 to retract; the rear driving chamber is connected to the second channel 1012. When the air source 21 supplies air, the telescopic rod 2 moves forward to drive the rotating nozzle 3 to extend.

[0035] Working principle: The air supply process of the air source 21 is precisely managed through the air inlet valve, so that the gas flows from the air pipe joint 17 through the flow channels on both sides of the cylinder body 7 into the driving chamber at the front or rear end, realizing the front and back movement of the telescopic rod 2, and then realizing the extension and retraction of the nozzle. When the tank or pipeline does not need to be cleaned, the rotating nozzle 3 is controlled to retract into the cylinder and be flush with the cylinder wall; when cleaning is required, the rotating nozzle 3 is controlled to enter the tank or pipeline to spray the cleaning liquid, which effectively reduces the risk of pipeline blockage and mold of the cleaning device, and improves the cleaning efficiency and safety.

[0036] The air supply from the air source 21 is controlled by the air inlet valve, so that the gas flows from the air pipe joint 17 through the flow channels on both sides of the cylinder body 7 and enters the front end driving chamber or the rear end driving chamber, thereby controlling the movement of the telescopic rod 2 to realize the extension and retraction of the nozzle. When the tank body or the pipeline does not need to be cleaned, the rotating nozzle 3 is controlled to retract into the cylinder body and be flush with the cylinder wall. When cleaning is required, the rotating nozzle 3 is controlled to enter the tank or the pipeline for cleaning, which effectively reduces the risk of pipeline blockage and mildew of the cleaning device.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
