Description
Technical Field
[0001] This utility model relates to the field of environmental protection dust removal equipment technology, specifically to a spherical dust suppression nozzle. Background Technology
[0002] Various processes in underground coal mining release large amounts of dust into the underground air, which has negative impacts on safety, health, and the environment. Spraying dust suppressants underground can effectively reduce dust dispersion.
[0003] Traditional dust suppression nozzles are mostly cone-shaped or fan-shaped nozzles, with limited spray angles and blind spots, making it difficult to achieve comprehensive dust suppression. Although increasing the number of nozzles can widen the coverage area, blind spots still exist, and it increases costs and material consumption. Furthermore, existing nozzles are functionally limited, typically only allowing for fully open or fully closed operation, failing to provide flexible and targeted spraying based on the distribution of dust sources on site, resulting in low resource utilization efficiency. A few adjustable nozzles have complex structures and cumbersome adjustment methods, and are prone to clogging due to impurities in the water after prolonged use, leading to poor reliability.
[0004] Therefore, there is an urgent need for a new type of nozzle structure that has a wide coverage, flexible and adjustable spraying modes, and is not prone to clogging. Utility Model Content
[0005] In view of the problems and shortcomings of the existing technology, this utility model provides a spherical dust suppression nozzle.
[0006] The technical solution of this utility model is as follows: A spherical dust suppression nozzle includes an upper hemisphere, a lower hemisphere, a spacer layer, an adjusting pipe, and a filter device. The upper and lower hemispheres are connected by the spacer layer to form a hollow spherical nozzle, and both are provided with atomizing holes. The top of the upper hemisphere has a water inlet hole, and its lower part is connected to a water inlet pipe. The bottom of the lower hemisphere is connected to an adjusting pipe coaxial with the water inlet pipe, and the lower part of the adjusting pipe is threadedly connected to the lower hemisphere. The spacer layer includes an outer wall, a first fixed layer and a second fixed layer connected to the upper and lower ends of the outer wall, and a movable layer disposed between the two. A fixed layer is connected to the bottom opening of the upper hemisphere, and a second fixed layer is connected to the top opening of the lower hemisphere, forming a sealed cavity between them. A movable layer is movably disposed within this cavity and is connected to an adjusting pipe passing through the second fixed layer, which has a fan-shaped channel. A water inlet pipe passes through the first fixed layer and its outlet extends into the sealed cavity and is located above the movable layer. The first and second fixed layers have upper and lower water inlets, respectively. Sealing plugs are provided on the upper and lower sides of the movable layer, with their positions corresponding to the upper and lower water inlets, respectively.
[0007] When the adjusting knob is turned, the movable layer can move up and down within the cavity under the drive of the adjusting tube. This allows the sealing plug of the movable layer to block the water passage upwards or downwards, thus switching between the upper and lower hemispheres. The fan-shaped channel is used to allow fluid to flow downwards into the lower hemisphere when the upper water passage is blocked.
[0008] The bottom of the adjustment tube is connected to an adjustment knob. This provides a convenient operating point, allowing users to easily rotate the adjustment tube to precisely control the position of the active layer.
[0009] A seal is provided at the connection between the adjusting pipe and the lower hemispherical shell. This effectively prevents water leakage from the threaded connection between the adjusting pipe and the lower hemispherical shell, ensuring the reliable sealing of the nozzle.
[0010] The sealing plug is made of an elastic material. Utilizing the deformation capability of the elastic material, it can tightly block the water passage, significantly improving the sealing effect and enhancing durability.
[0011] The inlet end of the water inlet is equipped with a filter device. This effectively filters impurities in the water, prevents clogging of the atomizing holes, ensures long-term stable operation of the nozzle, and extends its service life.
[0012] Two upper water inlets and two lower water inlets are provided, located on both sides of the water inlet pipe. This further enhances the sealing between the moving layer and the fixed layer, effectively preventing unintended cross-flow of water within the cavity.
[0013] Sealing gaskets are provided on the contact surfaces of the upper and lower sides of the active layer with the first and second fixed layers.
[0014] The water inlet pipe is made of flexible hose. The hose has a certain degree of flexibility and can bend accordingly when the movable layer moves up and down, avoiding structural interference and ensuring the smoothness of the adjustment process.
[0015] The beneficial effects of this utility model are: This utility model provides a spherical dust suppression nozzle that, through its unique spherical shell design and internal adjustable air gap structure, achieves flexible switching of spraying modes and wide-area coverage. Specifically, firstly, the spherical structure, combined with evenly distributed atomizing holes, enables 360° spraying without dead angles, effectively eliminating the coverage blind spots present in traditional nozzles. Secondly, the position of the movable layer can be easily controlled by rotating the adjustment knob, thus precisely achieving three modes: spraying only the upper hemisphere, spraying only the lower hemisphere, or spraying both hemispheres simultaneously. Users can make targeted adjustments according to the specific distribution of dust sources on site, significantly improving the utilization efficiency and dust suppression effect of the dust suppressant. Thirdly, the filter device at the water inlet effectively intercepts impurities in the water, and combined with the simple and smooth flow channel design, fundamentally reduces the risk of nozzle clogging, improving the long-term reliability and stability of the equipment. Fourthly, the overall structure is simple, without complex transmission mechanisms, resulting in low manufacturing costs and easy operation and maintenance. Attached Figure Description

Detailed Implementation
[0017] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.
[0018] Example The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1 and Figure 2 As shown, a spherical dust suppression nozzle includes an upper hemispherical shell 1, a lower hemispherical shell 2, a spacer layer 5, an adjustment tube 6, an adjustment knob 7, and a filter device 4.
[0019] The upper hemisphere 1 and the lower hemisphere 2 are connected by a spacer layer 5 to form a hollow spherical nozzle, which is provided with an atomizing hole 12 that communicates with the outside. The upper hemisphere 1 has a water inlet hole 3 at the top, and a water inlet pipe 8 is connected to the lower part of the water inlet hole 3. The lower hemisphere 2 is connected to an adjusting pipe 6 coaxial with the water inlet pipe 8 at the bottom. The lower part of the adjusting pipe 6 is threaded to the lower hemisphere 2, and a sealing element is provided at the connection. An adjusting knob 7 is connected to the bottom.
[0020] Preferably, but not limited to, the water inlet pipe 8 is a flexible hose. Several atomizing holes are provided, and are evenly distributed along the upper hemisphere 1 and the lower hemisphere 2.
[0021] Furthermore, a filter device 4 is provided at the inlet end of the water inlet 3. The filter device 4 is used to filter impurities in the fluid to avoid clogging the water inlet pipe 8 and the atomizing hole 12.
[0022] See Figure 2 and Figure 3 The air gap 5 includes an outer wall, a first fixed layer 51 and a second fixed layer 52 connected at the upper and lower ends of the outer wall, and a movable layer 53 disposed between the first fixed layer 51 and the second fixed layer 52. The first fixed layer 51 is connected to the bottom opening of the upper hemisphere 1, and the second fixed layer 52 is connected to the top opening of the lower hemisphere 2, forming a sealed cavity between the first fixed layer 51 and the second fixed layer 52. The movable layer 53 is movably disposed within the cavity between the first fixed layer 51 and the second fixed layer 52 and is connected to an adjusting pipe 6 passing through the second fixed layer 52, which has a fan-shaped channel. When the adjusting pipe 6 is rotated by the adjusting knob 7, the movable layer 53 can move up and down within the cavity under the drive of the adjusting pipe 6. The water inlet pipe 8 passes through the first fixed layer 51 and its outlet extends above the movable layer 53 within the cavity.
[0023] See Figures 2-4 The first fixed layer 51 and the second fixed layer 52 are respectively provided with an upper water passage hole 10 and a lower water passage hole 11. The movable layer 53 is provided with sealing plugs 54 on the upper and lower sides. The positions of the sealing plugs 54 on the upper and lower sides correspond to the upper water passage hole 10 and the lower water passage hole 11, respectively. This allows the movable layer 53 to block the upper water passage hole 10 when it moves upward to its limit position and block the lower water passage hole 11 when it moves downward to its limit position. When the upper water passage hole 10 is blocked, the lower water passage hole 11 is open, and when the lower water passage hole 11 is blocked, the upper water passage hole 10 is open.
[0024] To ensure the sealing performance of the upper water inlet 10 or the lower water inlet 11 in conjunction with the sealing plug 54, the sealing plug 54 is preferably made of an elastic material, such as rubber.
[0025] Additionally, see Figure 4 In a preferred embodiment, there are two upper water inlets 10 and two lower water inlets 11, which are respectively located on both sides of the water inlet pipe 8.
[0026] To further prevent water leakage, a seal is provided at the interface between the adjusting pipe 6 and the second fixed layer 52. Sealing gaskets 9 are provided on the upper and lower sides of the movable layer 53.
[0027] In use, water flows into the inlet pipe 8 through the inlet hole 3 and is filtered by the filter device 4 located at the inlet hole 3 to remove impurities. The filtered water then enters the sealed cavity formed by the first fixed layer 51 and the movable layer 53 through the inlet pipe 8. The adjusting knob 7 is then used to rotate the adjusting pipe 6, causing the movable layer 53 to move up and down to achieve the following three spraying modes: Spray the upper hemisphere separately At this time, the active layer 53 moves downward under the action of the adjusting pipe 6, and the sealing plug 54 is inserted downward into the lower water passage hole 11 of the second fixed layer 52, blocking the downward flow of fluid in the upper hemisphere shell 1. The fluid enters the upper hemisphere shell 1 only through the upper water passage hole 10, and then is sprayed outward through the atomizing hole 12. Spray the lower hemisphere separately The active layer 53 moves upward under the action of the adjusting pipe 6, and the sealing plug 54 is embedded in the upper water passage hole 10 of the first fixed layer 51, blocking the upward flow of fluid in the lower hemisphere shell 2. The fluid passes through the fan-shaped channel of the active layer 53 and enters the interior of the lower hemisphere shell 2 through the lower water passage hole 11, and then is sprayed outward through the atomizing hole 12. Spray both upper and lower hemispheres simultaneously The active layer 53 is located in the middle position, and the sealing plug 54 is not embedded in the water passage hole of any fixed layer. The fluid enters the interior of the upper and lower hemispherical shells at the same time and is sprayed through their respective atomizing holes 12.
[0028] During use, the adjustment tube 6 can be adjusted according to the dust concentration to switch between the three working modes mentioned above.
[0029] This invention uses a fine-tuning knob 7 to change the position of the movable layer 53, allowing it to move up and down. This, in turn, changes the usage of part or all of the upper and lower hemispherical shells, thus adjusting the spray volume. It features a simple structure, convenient operation, and excellent atomization effect, meeting the spraying needs of various scenarios. It is suitable for agricultural irrigation, industrial dust removal, and household cleaning. Furthermore, this invention consists of simple components, without complex transmission mechanisms; adjustment is achieved simply by rotating the knob. No additional nozzles are required, reducing procurement, installation, and maintenance costs and material consumption.
