Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0035] The magnetized spray assembly comprises a foam spray head 1, which is transmission-connected with a swing assembly, and the foam spray head 1 is rotationally arranged and connected with a foam generating assembly and an air supply assembly respectively;

[0036] The swing assembly includes a swing gear ring 47 fixed to the rear end of the foam nozzle 1 , the swing gear ring 47 is meshed with a first swing gear 45 and a second swing gear 46 coaxially arranged, and the first swing gear 45 and the second swing gear 46 are transmission-connected to the swing motor 44 .

[0037] The invention discloses a magnetized foam generating device for dust reduction. When in use, an air supply component and a water supply component supply water and air to the foam generating component, a large amount of foam is generated in the foam generating component and enters the magnetized injection component, the foam is magnetized in the magnetized injection component and then ejected, and is used for dust reduction treatment in a mine; a large amount of generated foam enters a foam nozzle 1 and is magnetized in the foam nozzle 1; the foam nozzle 1 is transmission-connected with a swing component, so that the foam nozzle 1 swings left and right during the foam ejection process, thereby expanding the ejection range of the foam nozzle 1 , expanding the efficiency and effect of dust reduction; when swinging, the output shaft of the swing motor 44 rotates toward the first swing gear 45 and the second swing gear 46, the first swing gear 45 and the second swing gear 46 are incomplete gears, and the two are staggered and do not mesh with the swing gear ring 47 at the same time, and the first swing gear 45 and the second swing gear 46 have opposite tooth directions, so when the two mesh with the swing gear ring 47 respectively, they provide driving forces in opposite directions for the foam nozzle 1, so that the foam nozzle 1 swings left and right, expanding the spray dust reduction range of the foam nozzle 1. The present invention has a simple structure, can quickly provide foam, and magnetize the foam, expanding the effect of foam dust reduction, and at the same time, by setting the foam nozzle 1 to swing left and right, the spray range of the foam nozzle 1 is expanded, and the range and efficiency of foam dust reduction are improved.

[0038] Further optimization scheme, the two sides of the foam nozzle 1 are respectively provided with a first fixed joint 2 and a second fixed joint 3 connected with the inner cavity of the foam nozzle 1, the first fixed joint 2 is rotatably arranged and connected with a first movable joint 4, the second fixed joint 3 is rotatably arranged and connected with a second movable joint 5, the first movable joint 4 is connected with the foam generating assembly, and the second movable joint 5 is connected with the air supply assembly. The first movable joint 4 is matched with the first fixed joint 2, and the second movable joint 5 is matched with the second fixed joint 3, which ensures that the foam and compressed air are connected, and also ensures that the foam nozzle 1 will not be restricted when deflected.

[0039] Furthermore, a sealed bearing 50 is provided between the first movable joint 4 and the first fixed joint 2, and a sealed bearing 50 is also provided between the second movable joint 5 and the second fixed joint 3, so as to ensure rotational flexibility while having a good sealing effect and ensuring the connection effect.

[0040] A further optimized solution is that a first conical cylinder 6 is provided in the inner cavity of the foam nozzle 1, and a first magnetized structure 7 is arranged around the outer wall of the first conical cylinder 6; the small end of the first conical cylinder 6 is fixedly connected to and communicated with an intermediate tube 8, and a second magnetized structure 9 is arranged around the outer side of the intermediate tube 8; the intermediate tube 8 is connected to a second conical cylinder 10, and the large end of the second conical cylinder 10 is away from the intermediate tube 8 and is provided with a spoiler 11, and the outer wall of the second conical cylinder 10 is connected to the air supply assembly through a plurality of air inlet holes 12. The foam generated by the foam generating assembly enters the inner cavity of the foam nozzle 1 under the action of the remaining compressed air. After entering the first conical tube 6, the foam is preliminarily magnetized by the first magnetizing structure 7. Then, the foam enters the intermediate tube 8 from the outlet at the small end of the first conical tube 6 and is further magnetized by the second magnetizing structure 9. The magnetized high-speed foam enters the second conical tube 10. At the same time, the air supply assembly supplies compressed air to the foam nozzle 1, which enters the second conical tube 10 through the air inlet 12 to further accelerate and pressurize the magnetized high-speed foam, so that the magnetized high-speed foam is ejected from the outlet of the foam nozzle 1 to form a large foam area for dust reduction.

[0041] Furthermore, the outlet end of the foam nozzle 1 of this embodiment is provided with a conical nozzle 48, and the outlet of the conical nozzle 48 is provided with a filter screen 49. The high-speed foam is further accelerated and pressurized when entering the conical nozzle 48, and impacts the filter screen 49, breaking the foam flow, expanding the coverage area, and improving the dust reduction effect.

[0042] Furthermore, the foam of the first conical tube 6 of the present embodiment enters the middle tube 8 through the large end and exits the small end, forming a structure similar to a venturi tube, so that the speed and pressure of the foam entering the middle tube 8 are greatly increased; the acceleration and pressurization of the fluid by the venturi tube is an existing technical principle and will not be repeated here.

[0043] In a further optimized solution, the first magnetization structure 7 includes a plurality of magnetization tubes 13 surrounding the outer wall of the first conical cylinder 6, and a magnetic liquid is filled in the magnetization tubes 13. Since the first conical cylinder 6 is a conical configuration, a plurality of independent magnetization tubes 13 are used to fit the outer wall of the first conical cylinder 6, and the foam is preliminarily magnetized by the magnetism generated by the magnetic liquid filled inside.

[0044] Furthermore, the magnetized liquid of this embodiment is a strong magnetic liquid, also called magnetic liquid or magnetic fluid, which is a new type of functional material. It combines the fluidity of liquid and the magnetism of solid magnetic material. It is a superparamagnetic material formed by a large number of magnetic micro-nano particles uniformly dispersed and suspended in an oil-based liquid (or other base carrier liquid). It can flow freely like a liquid and can be controlled by a magnetic field to move in a directional manner. Strong magnetic liquid has fluidity, magnetism and stability; strong magnetic liquid has both the fluidity of liquid and the magnetism of solid magnetic material, and can move in a directional manner under the action of a magnetic field; stability refers to the fact that the particle size in the magnetic fluid is very small (usually 3-15 nanometers), and under the influence of Brownian motion, it can remain suspended without aggregation in the absence of an external magnetic field, ensuring uniform magnetic distribution.

Compressed air enters the air distribution cavity 19 through the second fixed joint 3, and then enters the second cavity 21 through the air distribution holes 20 after air distribution, so that the pressure of the second cavity 21 increases, and then the compressed air enters the second conical cylinder 10 through the air inlet holes 12, further pressurizing and accelerating the foam in the second conical cylinder 10, increasing the pressure of the foam ejection, and expanding the range of foam dust reduction.

[0049] Furthermore, the air distribution holes 20 of the present embodiment are arranged at an angle, and their direction is inclined toward the second conical cylinder 10, which reduces the pressure loss of the high-pressure air and improves the efficiency of pressurization and acceleration.
