Description

Technical Field

[0001] The present application relates to the technical field of container cleaning equipment, and in particular to a spinning nozzle. Background Art

[0002] The cleaning and drying of containers is usually carried out by spraying cleaning liquid or high-temperature gas from a nozzle to rinse and dry the container surface.

[0003] In the prior art, the nozzles used for cleaning or drying containers generally include fixed and rotary types. The fixed nozzles are fixed with multiple nozzles. When cleaning or drying the container, the contact point where the liquid or gas flows out from the nozzles and reaches the container surface is fixed, so there are large blind spots, and the cleaning or drying of the container is not sufficient. The rotary nozzles can rotate, so when spraying liquid or gas, all parts of the container surface can be covered, and the cleaning effect is better. However, this type of rotary nozzle is usually made of metal materials such as stainless steel and has a complex transmission structure inside. When cleaning high-purity electronic chemical containers, it is prone to corrosion and does not meet the high cleanliness requirements of such containers.

[0004] Therefore, the inventor needs to design a new spin nozzle to overcome the above problems. Summary of the invention

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 3 As shown, a spin spray head comprises a delivery pipe 1 connected to an external delivery mechanism, a spray head body 2 is rotatably sleeved on the outer wall of the delivery pipe 1, a limit position assembly is arranged between the delivery pipe 1 and the spray head body 2, a receiving cavity is arranged between the delivery pipe 1 and the spray head body 2, a liquid outlet 3 is arranged on the delivery pipe 1, and a plurality of cleaning spray ports 4 and a plurality of self-spin spray ports 5 are arranged on the spray head body 2; when working, when cleaning or drying the container, the liquid or gas is transferred from the external delivery mechanism to the delivery pipe 1, and then passes through the delivery pipe 1, The liquid outlet 3 enters the accommodating chamber. When the accommodating chamber is filled with liquid or gas, the liquid or gas will be sprayed out from the cleaning spray port 4 and the spinning spray port 5. The liquid or gas sprayed from the cleaning spray port 4 will reach the surface of the container to achieve cleaning or drying. When sprayed through the spinning spray port 5, recoil force will be generated to drive the nozzle body to rotate. Through the rotation of the nozzle body, the liquid or gas sprayed from the cleaning spray port 4 will cover the surface of the container, thereby enhancing the cleaning or drying effect. The limit assembly prevents the nozzle body 2 from sliding when it rotates.

[0031] The limiting assembly includes an upper end cover 6 and a lower end cover 7, both of which are fixedly connected to the delivery pipe 1, and the top surface and bottom surface of the nozzle body 2 are in contact with the upper end cover 6 and the lower end cover 7 respectively; the lower end cover 7 has a sealing shaft section 10, which is inserted into the delivery pipe 1, and a first thread 11 that cooperates with the delivery pipe 1 is provided between the sealing shaft section 10; the upper end cover 6 and the delivery pipe 1 have a second thread 12 that cooperates with each other; when working, the upper end cover 6 and the lower end cover 7 are fixedly connected to the delivery pipe 1 by threads, and abut against the two ends of the nozzle body 2, so that the nozzle body 2 will not slide relative to the delivery pipe 1.

[0032] The nozzle body 2 has a center hole 8, and the diameter of the center hole 8 is equal to the outer diameter of the delivery tube 1. When working, the delivery tube 1 is directly inserted into the center hole 8 with the same inner diameter, so that the liquid or gas in the accommodating cavity is not easy to leak out from the gap between the inner wall of the center hole 8 and the outer wall of the delivery tube 1, thereby making the pressure of the liquid or gas higher when spraying, and the cleaning or drying effect better.

[0033] A plurality of annular grooves 9 are provided on the outer wall of the delivery pipe 1, and the accommodating chamber is a cavity formed by the inner wall of the central hole 8 and the surface of the annular groove 9; during operation, the liquid outlet 3 is provided at the annular groove 9, and the liquid or gas enters the annular groove 9 after coming out of the liquid outlet 3, and the annular groove 9 is connected with the cleaning liquid spray port 4 and the self-spinning liquid spray port 5. After the annular groove 9 is filled, the liquid is sprayed out from the cleaning liquid spray port 4 and the self-spinning liquid spray port 5.

[0034] The self-spinning liquid jet port 5 extends outward from the inner wall of the center hole 8 and penetrates the nozzle body 2. The angle between the tangent direction at the outer port of the self-spinning liquid jet port 5 and the diameter direction of the nozzle body 2 is an acute angle. When working, the gas or liquid ejected from the self-spinning liquid jet port 5 will generate recoil, which will generate a tangential force on the nozzle body, thereby causing the nozzle body 2 to rotate, that is, the nozzle body spins. It should be noted that the path of the self-spinning liquid jet port 5 in the nozzle body can be irregular. In addition to the straight line, the curved line can also meet the requirements as long as the jet ejected from its opening does not coincide with the diameter direction of the nozzle body 2.

[0035] The cleaning liquid spray port 4 extends outward from the inner wall of the center hole 8 and penetrates the nozzle body 2, and the cleaning liquid spray port 4 is flat. When working, the hole-shaped jet has a poor cleaning effect on a large area of ​​dirt, while the liquid sprayed from the flat cleaning liquid spray port 4 has a better cleaning effect. In order to make the gas or liquid sprayed from the cleaning liquid spray port 4 cover a wider area, the cleaning liquid spray port 4 can also be set to a shape with a certain pitch angle, so that the liquid and gas can be sprayed upward, thereby cleaning or drying the top of the container.

[0036] All of the cleaning liquid spray ports 4 and all of the spinning liquid spray ports 5 are distributed in a circular array along the central axis of the nozzle body 2; the circular array distribution allows the nozzle body 2 to be subjected to a more balanced force when rotating, the nozzle body 2 is less likely to vibrate, and the operation is more stable.

[0037] The delivery pipe 1 and the nozzle body 2 are made of PVDF or PTFE. When working, these two materials are chemically stable and not easily corroded, and their physical properties such as rigidity and wear resistance are also relatively excellent, and their service life is longer.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
