Description

Technical Field

[0001] This utility model relates to the field of downhole spraying technology, and in particular to a spray head for downhole spraying. Background Technology

[0002] Winters in iron ore mines are dry, and the high levels of dust generated by vehicles traveling in the loading tunnels and lower transport roadways pose a health hazard to workers. Therefore, it is essential to install spray systems for dust suppression. Existing spray systems often use hollow cone wide-angle nozzles with a turbulent structure protruding from the nozzle pipe. When liquid flows through the pipe, its velocity increases and pressure decreases at the narrowest point of the nozzle, resulting in high-speed atomization of approximately 10-micron spray particles at the nozzle exit. However, because the narrow nozzle is necessary to change the flow velocity, impurities in the production water often cause blockages. Even with the addition of filters in the downstream pipeline, blockages or damage are common in practice. Therefore, designing and selecting a suitable nozzle type to reduce clogging, extend nozzle lifespan, and reduce maintenance and replacement frequency is imperative. Utility Model Content

[0003] This invention provides a nozzle for downhole spraying to solve the problems mentioned in the background art.

[0004] To address the aforementioned issues, this utility model provides a downhole spray nozzle, comprising a high-pressure nozzle body, a connecting seat threaded to the rear side of the high-pressure nozzle body, and a plurality of high-pressure nozzles threaded to the front side of the high-pressure nozzle body. A raised arc-shaped filter screen is installed inside the connecting seat.

[0005] Preferably, an external hexagonal component is fixed on the outer surface of the end of the connecting seat away from the high-pressure nozzle body.

[0006] Preferably, the diameter of the high-pressure nozzle is larger than the mesh diameter of the arc-shaped filter screen.

[0007] The beneficial effects of adopting the above technical solutions are:

[0008] The water supply pipe is connected to the connector, allowing water to enter the high-pressure nozzle body through the connector. The water is then pressurized by the high-pressure nozzle and atomized before being sprayed out from the high-pressure nozzle. The connector is equipped with a filter screen, which, through its arc shape, can filter out larger particles and impurities. The arc shape of the filter screen also makes it less prone to clogging, reducing the probability of clogging the high-pressure nozzle. The high-pressure nozzle is threadedly connected to the high-pressure nozzle body, making the high-pressure nozzle detachable for easy maintenance and unclogging, thus extending the service life of the equipment and reducing the frequency of equipment replacement.

[0013] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-3 In this embodiment, a downhole spray nozzle includes a high-pressure nozzle body 1, a connecting seat 2 threadedly connected to the rear side of the high-pressure nozzle body 1, a plurality of high-pressure nozzles 3 threadedly connected to the front side of the high-pressure nozzle body 1, and a raised arc-shaped filter screen 4 installed inside the connecting seat 2.

[0017] Through the above technical solution, the threaded connection between the high-pressure nozzle body 1 and the connecting seat 2 makes it easy to disassemble the high-pressure nozzle body 1 and the connecting seat 2, thereby facilitating the cleaning of the inside of the high-pressure nozzle body 1. The threaded connection between the high-pressure nozzle 3 and the high-pressure nozzle body 1 makes it easy to install and remove the high-pressure nozzle 3 and the high-pressure nozzle body 1, thereby facilitating the unblocking and cleaning of the high-pressure nozzle and improving the service life of the equipment. The arc-shaped filter screen 4 can filter particulate impurities in the water, and the filter screen is set as a raised arc shape, thus making it less prone to clogging.

[0018] Preferably, an external hexagonal component 21 is fixed on the outer surface of the end of the connecting seat 2 away from the high-pressure nozzle body 1.

[0019] Through the above technical solution, the external hexagonal component 21 on the connecting seat 2 facilitates the connection seat 2 to be installed and removed from the external water source pipe using tools such as wrenches.

[0020] Preferably, the diameter of the high-pressure nozzle 3 is larger than the mesh diameter of the arc-shaped filter screen 4.

[0021] Through the above technical solution, the internal diameter of the high-pressure nozzle 3 is larger than the mesh diameter of the arc-shaped filter screen 4, so that the impurities contained in the filtered water can be directly sprayed out from the high-pressure nozzle 3, reducing the probability of clogging of the high-pressure nozzle 3.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
