Description

Technical Field

[0001] This utility model belongs to the technical field of coal preparation production system equipment, specifically relating to a self-cleaning anti-clogging nozzle design. Background Technology

[0002] Traditional sprinkler heads play an indispensable role in a wide range of industrial, agricultural, and everyday cleaning applications. However, a significant problem they often face during use is clogging. Water sources inevitably contain various impurities, such as tiny particles of silt, suspended particulate matter, and other insoluble substances. These substances easily deposit or become stuck in the tiny pores of the nozzle as they flow through the sprinkler head, significantly reducing the spray effect or even completely eliminating the spray function. Clogging not only affects the normal use of the sprinkler head but can also lead to abnormal system pressure, further causing equipment malfunctions.

[0003] Traditional solutions to nozzle clogging often rely on manual intervention. This typically requires operators to shut off the water supply, disassemble the nozzle, and then manually remove the internal deposits using brushes, needles, or other tools. This process is not only time-consuming and labor-intensive, increasing labor costs, but also, in certain emergency or continuous operation scenarios, downtime for cleaning can severely impact work efficiency and production schedules. Furthermore, for high-end nozzles with complex structures and sophisticated designs, frequent disassembly and cleaning can damage their precision components, shortening their lifespan and further increasing maintenance costs.

[0004] Given the above problems, it is particularly important to design an anti-clogging nozzle that can effectively prevent clogging while being easy to maintain and clean. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an anti-clogging nozzle that can prevent clogging and is easy to maintain and clean in daily life.

[0006] To solve the above-mentioned technical problems, this utility model provides a self-cleaning anti-clogging nozzle, comprising a main body, a sealing ring, and an adjusting nozzle. The main body has an eccentrically positioned water outlet, and the water outlet end of the main body is equipped with an adjusting nozzle. A sealing ring for sealing is provided between the main body and the adjusting nozzle. The adjusting nozzle has an eccentrically positioned spray hole for spraying water, which is configured and used with the water outlet. A connecting member for connecting the adjusting nozzle to the main body is fitted on the outer side of the adjusting nozzle. The connecting member is threadedly connected to the main body. By controlling the tightness of the connecting member and the main body, the adjusting nozzle can rotate relative to the main body, thereby changing the misalignment between the spray hole and the water outlet, and achieving the self-cleaning function.

[0007] Through the above structure: water flow from the eccentricity of the body outlet, rotating the adjusting nozzle, when the nozzle hole rotation to a certain degree of coincidence with the body outlet, water can be through the nozzle hole of the adjusting nozzle spray, realize the normal function of the water. Because the nozzle hole and the outlet are eccentric, to a certain extent, the water flow can produce a certain rotation or deviation effect, so that the water has directionality and coverage. When the nozzle is clogged, it needs to be self-cleaning, the rotating adjusting nozzle can change the degree of misalignment of the nozzle hole and the outlet. At this time, the water flow changes in the process of flowing from the outlet to the nozzle hole due to the change of the channel shape and the misalignment setting, which will produce complex water flow such as turbulence and vortex. The complex water flow can produce scouring and disturbance effect on the impurities, dirt and other impurities that may exist in the nozzle, preventing the impurities from accumulating and clogging near the outlet or nozzle hole; realizing the function of self-cleaning.

[0008] Preferably, the cross-sectional shape of the outlet on the body is a rhombus, and the cross-sectional shape of the nozzle hole on the adjusting nozzle is a rhombus; the shape of the rhombus hole helps to a certain extent to produce a certain rotation or shear force when the fluid is sprayed, which can help to remove impurities and dirt around the hole, and has a certain self-cleaning ability.

[0009] Preferably, the end of the adjusting nozzle in contact with the body is provided with a boss, the connecting piece is a hollow structure, one end of the connecting piece is provided with a thread connected with the body, the other end of the connecting piece is provided with a limiting ring limiting the axial movement of the boss, and the connecting piece is sleeved on the outside of the adjusting nozzle and then connected with the body through threads.

[0010] Preferably, the end of the body close to the adjusting nozzle is provided with a sealing boss, the adjusting nozzle is provided with a avoiding groove matched with the sealing boss, and the sealing boss is arranged on the inside of the avoiding groove.

[0011] Preferably, the size of the outlet on the body to the center of rotation of the body is equal to the size of the nozzle hole on the adjusting nozzle to the center of rotation of the adjusting nozzle. By rotating the adjusting nozzle, the outlet and the nozzle hole can be sprayed with a small through area, and at the same time, the rotating adjusting nozzle can control the outlet and the nozzle hole with the largest through area, so as to facilitate the discharge of the internal clogging of the nozzle.

[0012] As described above, the above structure can effectively prevent clogging, and facilitate daily maintenance and cleaning. BRIEF DESCRIPTION OF DRAWINGS
