[0002] A large amount of dust is generated during the mining process, which not only affects the health of the workers, but also affects the work efficiency of the workers. A wet dust collector is needed to separate the dust from the flue gas. The existing wet dust collector device usually sucks the dusty air into the device through a centrifuge, sprays water to achieve the dust removal effect, and then discharges the gas. However, the dust removal effect of only spraying water is not good. Therefore, we propose a coal mining wet dust removal device to solve the problem of poor dust removal effect of the existing device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1-Figure 5 As shown, the utility model provides a wet dust removal device for coal mining, including an assembly cylinder 1, a fixed seat 101 is arranged on the top of the assembly cylinder 1, a rotating bearing 102 is sleeved on the bottom of the fixed seat 101, the assembly cylinder 1 is connected to the fixed seat 101 through the rotating bearing 102, a water inlet pipe 103 is installed on the top of the assembly cylinder 1, a sealing ring 104 is fixedly connected around the bottom of the assembly cylinder 1, a closing cover 105 is threadedly connected to the bottom of the assembly cylinder 1, and a control component 2 is arranged around the assembly cylinder 1, and the control component 2 includes a plurality of assembly Window 201, multiple assembly windows 201 are evenly distributed around the axis of the assembly tube 1, the assembly window 201 is built with an assembly pipe 210, and one end of the assembly pipe 210 close to the assembly window 201 is provided with multiple limit grooves 211, and the limit seat 206 is slidably connected to the wall of the limit groove 211, and multiple atomizing heads 212 are installed on one side of the assembly pipe 210, and the end of the assembly pipe 210 away from the assembly tube 1 is fixedly connected with a screw wheel 213, and water enters the assembly tube 1 from the water inlet pipe 103 at the top of the assembly tube 1 to form a certain water pressure. The assembly tube 1 is connected to the top fixed seat 101 through a rotating bearing 102, so that the assembly tube 1 can be flexibly rotated relative to the fixed seat 101, which provides a basis for subsequent adjustment of the atomization spray direction, and the assembly windows 201 around the assembly tube 1 are provided with assembly pipes 210, and the end of the assembly pipe 210 close to the assembly window 201 is fixed by the cooperation of the limit seat 206 and the limit groove 211, so that the assembly pipe 210 is stably installed and can rotate around the axis. A plurality of atomizing heads 212 installed on one side of the assembly tube 210 atomize water into tiny particles under the action of water pressure and spray them out. When the screw wheel 213 at one end of the assembly tube 210 is rotated, the spraying direction of the atomizing head 212 can be changed, thereby realizing rotary atomization spraying, so that the sprayed water mist can cover the surrounding space more comprehensively and increase the contact area with the dust.

[0024] Furthermore, a plurality of mounting grooves 202 are provided on the inner wall of the assembly window 201, and the plurality of mounting grooves 202 are evenly distributed around the axis of the assembly window 201. A fixed cylinder 203 is fixedly connected to both sides of the inner wall of the mounting groove 202, and a rotating roller 204 is built in the fixed cylinder 203. Both ends of the rotating roller 204 are rotatably connected to the bottom of the inner cavity of the fixed cylinder 203 on both sides. A coil spring 205 is sleeved on both ends of the rotating roller 204, and the coil spring 205 is placed in the fixed cylinder 203. One end of the coil spring 205 is connected to the fixed cylinder 203. 03 inner wall, the other end of the coil spring 205 is fixedly connected to the surface of the rotating roller 204, the surface of the rotating roller 204 is sleeved with a limit seat 206, one end of the limit seat 206 is fixedly connected to the rotating roller 204, one side of the limit seat 206 is an elliptical surface 207, one side of the mounting groove 202 is provided with an embedding groove 209, and the other side of the limit seat 206 is a vertical surface 208. When the assembly tube 210 rotates around its axis, the limit seat 206 connected to the assembly tube 210 will also rotate. The limit seat 206 is fixedly connected to one end of the rotating roller 204, and the rotating roller 204 is in the fixed cylinder 203 in the mounting groove 202 and has coil springs 205 sleeved at both ends. During the rotation of the assembly tube 210, the rotating roller 204 will rotate accordingly with the movement of the limit seat 206. Since one end of the coil spring 205 is fixedly connected to the inner wall of the fixed cylinder 203 and the other end is fixedly connected to the surface of the rotating roller 204, when the rotating roller 204 rotates, the coil spring 205 will undergo elastic deformation to store energy. As the assembly tube 210 rotates to a suitable angle, the elastic restoring force of the coil spring 205 will prevent the rotating roller 204 from continuing to rotate at will, thereby indirectly playing a role of clamping and fixing the limit seat 206 and the assembly tube 210 connected thereto. In other words, the coil spring 205 utilizes its own elastic characteristics, and when the assembly tube 210 rotates to a desired position, by constraining the rotating roller 204, the entire assembly tube 210 can be stably maintained at the position, preventing it from easily deviating or shaking due to external interference and other factors. This clamping and fixing effect ensures that the assembly tube 210 can remain stable after the spraying direction of the atomizing head 212 is adjusted, so that the water mist can be continuously and stably sprayed out in the set direction. In this way, whether it is concentrated dust reduction in a local area or uniformly covering a larger area, the accuracy and continuity of the spraying direction can be guaranteed, which helps to improve the efficiency and stability of the contact between dust and water mist, and thus stabilize the dust removal effect.

[0025] The rotary atomization spraying method allows the water mist to be more evenly dispersed in the air and fully contact the dust particles. Compared with the traditional fixed-direction spraying, the rotary spraying can make the water mist form a more complex motion trajectory in the space, increasing the chances of dust and water mist colliding and combining, thereby increasing the dust's dependence on the water mist, making it easier for the dust to be captured and settled by the water mist, effectively improving the dust removal effect.

[0026] With the unique rotating roller 204 and limit seat 206 structure in the assembly window 201, the spray area of ​​the atomizing head 212 can be conveniently adjusted according to the actual working scene and dust removal requirements. In different mining areas or dust distribution conditions, the coverage of the water mist can be flexibly changed to ensure that a good dust reduction effect can be achieved in various complex coal mining environments, thereby improving the adaptability and practicality of the device, being able to better meet the diversified dust reduction requirements in the coal mining process, helping to improve the air quality in the workplace, protecting the health and production safety of miners, and also helping to improve the efficiency and sustainability of coal mining operations.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
