Description

Technical Field

[0001] This utility model relates to the field of spray dust removal technology, and in particular to a spray head and spray device. Background Technology

[0002] With the continuous development of industrialization, many industries are facing the problem of dust pollution. Especially in places where mining, construction, and material storage are carried out, large amounts of dust can have a serious impact on the environment and human health, so specialized dust suppression equipment has emerged.

[0003] Dustfall refers to airborne particulate matter that falls naturally to the ground. Most of these particles have a diameter of 10 micrometers or larger, and the unit of measurement is the amount of material deposited on a unit area of ​​the ground within a certain time period. Monitoring the natural deposition of atmospheric dust is one of the earliest routine monitoring projects for air pollutants. Dustfall reflects the natural deposition of particulate matter and is expressed as the weight of particulate matter deposited per unit area per month.

[0004] However, existing dust suppression equipment cannot fully form water mist in the air to increase the contact area with dust. Utility Model Content

[0005] In view of this, the present invention provides a spray head and a spray device, the main purpose of which is to improve the efficiency of water mist formation during spray dust removal.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] On the one hand, this utility model provides a spray head, which includes: a hollow sphere and a dispersion section;

[0008] The surface of the hollow sphere is evenly distributed with multiple through holes;

[0009] The dispersion section includes a water inlet pipe and a cone-shaped body. The water inlet pipe is connected to the surface of the hollow sphere, and the bottom surface of the cone-shaped body is fixedly connected to the inner surface of the hollow sphere. The central axis of the water inlet pipe coincides with the central axis of the cone-shaped body.

[0010] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0011] Optionally, the central axis of the water inlet pipe and the central axis of the cone are both coincident with the diameter direction of the hollow sphere.

[0012] Optionally, the generatrix of the cone is wavy.

[0013] On the other hand, the present invention also provides a spraying device, which includes: a fixed plate, a guide pipe, a plurality of the aforementioned spray heads and a Venturi mechanism;

[0014] The fixing plate is installed at the edge of the spray area;

[0015] The guide tube is rotatably connected to the surface of the fixed plate;

[0016] One end of the water inlet pipe is connected to the wall of the guide pipe, and the other end is connected to the surface of the hollow sphere;

[0017] The Venturi mechanism includes an outer tube and an inner conical tube. The outlet of the outer tube is connected to the wall of the guide tube via a flexible hose. The inner conical tube is coaxially disposed within the outer tube, with its small end facing the outlet of the outer tube. The outer tube wall surrounding the inner conical tube is connected to the air intake pipe.

[0018] Optionally, the surface of the fixing plate is provided with a plurality of annular components arranged in sequence, and the guide tube is rotatably connected to the plurality of annular components respectively.

[0019] Optionally, it also includes a drive motor, which is mounted on the fixed plate, and the output shaft of the drive motor is coaxially connected to the guide pipe.

[0020] By employing the above technical solution, this utility model has at least the following advantages:

[0021] When using the spray head, high-pressure water enters the hollow sphere through the inlet pipe. The water flow evenly impacts the circumference of the cone. On the circumference of the cone, the water flow direction is deflected and flows out through multiple through holes on the surface of the hollow sphere.

[0022] During the above process, the high-pressure water flow direction is deflected on the circumferential side of the cone, thereby forcing the high-pressure water flow to pre-diffuse towards the surface of the hollow sphere. Combined with the multiple through holes on the surface of the hollow sphere, the water flow is further diffused, thereby improving the efficiency of the spray head spraying atomized water and ultimately improving the dust removal efficiency.

[0029] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 4 and Figure 5 As shown, in one embodiment of the present invention, a spray head is provided, which includes: a hollow sphere 1 and a dispersion section;

[0032] The surface of the hollow sphere 1 is evenly distributed with multiple through holes 2;

[0033] The dispersion section includes a water inlet pipe 3 and a cone 4. The water inlet pipe 3 is connected to the surface of the hollow sphere 1, and the bottom surface of the cone 4 is fixedly connected to the inner surface of the hollow sphere 1. The central axis of the water inlet pipe 3 coincides with the central axis of the cone 4.

[0034] The working process of the spray head is as follows:

[0035] When using the spray head, high-pressure water enters the hollow sphere 1 along the inlet pipe 3. The water flow evenly impacts the circumferential surface of the cone 4. On the circumferential surface of the cone 4, the water flow direction is deflected and flows out through multiple through holes 2 on the surface of the hollow sphere 1.

[0036] During the above process, the high-pressure water flow direction is deflected on the circumferential side of the cone 4, thereby forcing the high-pressure water flow to pre-diffuse towards the surface of the hollow sphere 1. Combined with the multiple through holes 2 on the surface of the hollow sphere 1, the water flow is further diffused, thereby improving the efficiency of the spray head spraying atomized water and ultimately improving the dust removal efficiency.

[0037] Specifically, the diameter of the bottom circle of the cone 4 is equal to the inner diameter of the water inlet pipe 3. The diameter of the water column entering the hollow sphere 1 through the water inlet pipe 3 is equal to the diameter of the bottom circle of the cone 4. At the same time, the central axis of the water inlet pipe 3 coincides with the central axis of the cone 4. In this way, the water entering the hollow sphere 1 first fully contacts the circumferential surface of the cone 4 before impacting the inner surface of the hollow sphere 1, ensuring that the high-pressure water is fully diffused inside the hollow sphere 1.

[0038] like Figure 5 As shown, in a specific embodiment, the central axis of the water inlet pipe 3 and the central axis of the cone 4 both coincide with the diameter direction of the hollow sphere 1.

[0039] In this embodiment, specifically, the central axis of the cone 4 coincides with the diameter direction of the hollow sphere 1, and the distance between different positions on the circumference of the same radial section of the cone 4 and the inner surface of the hollow sphere 1 remains consistent, so that the high-pressure water flow is diffused more evenly.

[0040] like Figure 5 As shown, in a specific embodiment, the generatrix of the cone 4 is wavy.

[0041] In this embodiment, specifically, the high-pressure water column entering the hollow sphere 1 through the water inlet pipe 3 impacts the peripheral side of the cone 4. When the high-pressure water column impacts the trough of the peripheral side, the high-pressure water will flow along the wavy surface to the crest. This can promote the high-pressure water to change direction and diffuse towards the inner surface of the hollow sphere 1. The wavy peripheral side of the cone 4 plays a role in guiding the direction of the high-pressure water.

[0042] Meanwhile, the wavy cone 4 has smooth curved surfaces on its sides, so the impact of high-pressure water flow on the circumference of the cone 4 will not significantly deplete the kinetic energy of the high-pressure water flow.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, another embodiment of the present invention also provides a spraying device, which includes: a fixing plate 5, a guide pipe 6, a plurality of the aforementioned spray heads and a Venturi mechanism;

[0044] The fixing plate 5 is installed at the edge of the spray area;

[0045] The guide pipe 6 is rotatably connected to the surface of the fixed plate 5;

[0046] One end of the water inlet pipe 3 is connected to the wall of the guide pipe 6, and the other end is connected to the surface of the hollow sphere 1;

[0047] The Venturi mechanism includes an outer tube 7 and an inner conical tube 8. The outlet of the outer tube 7 is connected to the wall of the guide tube 6 via a flexible hose 9. The inner conical tube 8 is coaxially disposed inside the outer tube 7, with the small end of the inner conical tube 8 facing the outlet of the outer tube 7. The wall of the outer tube 7 surrounding the inner conical tube 8 is connected to the air intake pipe 10.

[0048] In this embodiment, specifically, the inlet of the outer pipe 7 is connected to a high-pressure water conveying device. After the high-pressure water enters the outer pipe 7, it first flows through the inner conical pipe 8. The high-pressure water flows through the small end of the inner conical pipe 8. Due to the Venturi effect, a negative pressure zone is formed between the inner conical pipe 8 and the pipe wall of the outer pipe 7. Outside air enters the negative pressure zone of the outer pipe 7 through the air inlet pipe 10. Thus, the air and water flow mix in the outer pipe 7, so that the water entering the guide pipe 6 contains a certain amount of air bubbles. On this basis, in the hollow sphere 1, due to the bursting of air bubbles, the high-pressure water can have greater kinetic energy, thereby further increasing the speed of the high-pressure water when passing through multiple through holes 2, and further improving the atomization degree of the sprayed water flow.

[0049] Specifically, the edge of the spraying area can be the edge of the pit 13 of an open-pit coal mine. The lower side of the fixing plate 5 is fixed to the edge of the pit 13 by anchor bolts. The guide pipe 6 is rotatably connected to the surface of the fixing plate 5. As the guide pipe 6 rotates, the extension direction of the water inlet pipe 3 changes accordingly, the position of the hollow sphere 1 changes accordingly, and the direction of the water mist spray changes accordingly.

[0050] like Figure 1 As shown, specifically, multiple water inlet pipes 3 are arranged sequentially along the axial direction of the guide pipe 6, and the multiple water inlet pipes 3 are parallel to each other, so that the radial positions of multiple hollow spheres 1 relative to the guide pipe 6 are kept consistent, so that the water mist sprayed from the surface of multiple hollow spheres 1 sequentially forms a water wall, which blocks the dust raised in the mine pit 13.

[0051] like Figure 1 As shown, specifically, the hose 9 is made of rubber or PE material. One end of the hose 9 is fixedly connected to the outlet of the outer tube 7, and the other end is connected to the wall of the guide tube 6 through multiple branches. The hose 9 can deform in accordance with the rotation of the guide tube 6.

[0052] like Figure 1 , Figure 4 As shown, in a specific embodiment, the surface of the fixing plate 5 is arranged with a plurality of annular components 11, and the guide pipe 6 is rotatably connected to the plurality of annular components 11 respectively.

[0053] In this embodiment, each annular component 11 is bolted to the surface of the fixing plate 5, and the guide tube 6 passes through multiple annular components 11 in sequence, thereby stabilizing the relative position of the guide tube 6 and the fixing plate 5.

[0054] like Figure 1 As shown, in a specific embodiment, a drive motor 12 is also included. The drive motor 12 is mounted on the fixed plate 5, and the output shaft of the drive motor 12 is coaxially connected to the guide pipe 6.

[0055] In this embodiment, specifically, the drive motor 12 is installed at the edge of the mine pit 13 at the end of the fixing plate 5 by anchor bolts. The drive motor 12 drives the guide pipe 6 to rotate, thereby changing the extension direction of the water inlet pipe 3.

[0056] Specifically, the drive motor 12 is a stepper motor. By changing the step angle of the stepper motor, the extension direction of the water inlet pipe 3 is changed, and ultimately the direction of the water mist sprayed out by the hollow sphere 1 is changed.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
