Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology, specifically a dust suppression device for coal yards. Background Technology

[0002] In coal storage and transfer sites such as coal yards, a large amount of dust is generated during the loading, unloading, stacking and transportation of coal. This dust not only pollutes the surrounding environment and affects air quality, but may also harm the health of workers. Long-term exposure to high concentrations of dust can easily lead to occupational diseases such as pneumoconiosis. In addition, the flying dust may also cause safety hazards such as dust explosions.

[0003] To effectively control dust pollution in coal yards, traditional dust suppression methods mainly involve covering with dust nets. However, existing methods still have some obvious shortcomings. Covering with dust nets requires a lot of manpower and resources, and the dust nets are easily damaged and need to be replaced regularly, increasing operating costs. With the increasing awareness of environmental protection and the advancement of technology, it is particularly important to develop a high-efficiency, energy-saving, and environmentally friendly dust suppression device for coal yards. This device should be able to automatically adjust the dust suppression angle and range to adapt to the dust suppression needs under different working conditions. Therefore, a dust suppression device for coal yards is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust suppression device for coal yards, which has the advantages of good dust suppression effect and easy adjustment of dust suppression angle, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for a coal yard, comprising a body, a dust suppression cylinder fixedly connected to the top of the body, a fan fixedly connected inside the dust suppression cylinder, a transmission mechanism provided inside and at the top of the body, a water supply mechanism fixedly connected to one end of the body, and a collection mechanism fixedly connected to the bottom of the dust suppression cylinder.

[0006] Furthermore, the transmission mechanism includes a motor fixedly connected to the inside of the machine body, a rotating disk fixedly connected to the top of the motor, a bracket fixedly connected to the top of the rotating disk, and an electric push rod hinged to the top of the rotating disk.

[0007] Furthermore, the collection mechanism includes a support plate fixedly connected to the bottom of the dust collection cylinder, and a collection box is provided on the top of the support plate.

[0008] Furthermore, the output shaft of the electric push rod is hinged to the bottom of the dust collection cylinder, and the dust collection cylinder is hinged inside the bracket.

[0009] Furthermore, a magnet is provided inside the support plate, the collection box is made of metal, and the collection box is attached to the top of the support plate.

[0010] Furthermore, the water supply mechanism includes a water tank fixedly connected to one end of the machine body, an inlet pipe fixedly connected to the top of the water tank, a water pump fixedly connected inside the machine body, a pumping pipe fixedly connected to one end of the water pump, an output pipe fixedly connected to the top of the water pump, and an atomizing nozzle fixedly connected to the top of the output pipe.

[0011] Furthermore, the atomizing nozzle is located inside the dust suppression cylinder, and the water pumping pipe is connected to the water supply tank.

[0012] Furthermore, the top end of the output pipe is fixedly connected to the inside of the dust collection cylinder, the bottom end is movably connected to the inside of the rotating disk, and the bottom end of the output pipe is a flexible hose.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1.

At the same time, the motor in the transmission mechanism drives the rotating disk to rotate, which in turn drives the dust suppression cylinder to rotate horizontally. The electric push rod adjusts the pitch angle of the dust suppression cylinder, realizing flexible adjustment of the dust suppression angle and range, which greatly improves the dust suppression efficiency.

[0014] 2. The dust suppression device for coal yards features a cleverly designed support plate and collection box in its collection mechanism. The collection box is magnetically attached to the top of the support plate, facilitating installation and disassembly. During dust suppression, any water droplets generated from insufficient atomization or water mist detaching from the inner wall of the dust suppression cylinder fall into the collection box, preventing water droplet pollution of the ground and waste of water resources.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The dust suppression device for a coal yard in this embodiment includes a body 1, a dust suppression cylinder 2 fixedly connected to the top of the body 1, a fan 201 fixedly connected inside the dust suppression cylinder 2, a transmission mechanism 4 provided inside and at the top of the body 1, a water supply mechanism 5 fixedly connected to one end of the body 1, and a collection mechanism 3 fixedly connected to the bottom of the dust suppression cylinder 2.

[0019] The transmission mechanism 4 includes a motor 401 fixedly connected inside the body 1, a rotating disk 402 fixedly connected to the top of the motor 401, a bracket 403 fixedly connected to the top of the rotating disk 402, an electric push rod 404 hinged to the top of the rotating disk 402, the output shaft of the electric push rod 404 hinged to the bottom of the dust collection cylinder 2, and the dust collection cylinder 2 hinged inside the bracket 403.

[0020] The motor 401 in the transmission mechanism 4 drives the rotating disk 402 to rotate, which in turn drives the dust collection cylinder 2 to rotate horizontally. The electric push rod 404 adjusts the pitch angle of the dust collection cylinder 2, realizing flexible adjustment of the dust collection angle and range, which greatly improves the dust collection efficiency.

[0021] Secondly, the collection mechanism 3 includes a support plate 301 fixedly connected to the bottom of the dust collection cylinder 2. A collection box 302 is provided on the top of the support plate 301. A magnet is provided inside the support plate 301. The collection box 302 is made of metal and is attached to the top of the support plate 301.

[0022] The support plate 301 and collection box 302 in the collection mechanism 3 are ingeniously designed. The collection box 302 is magnetically attached to the top of the support plate 301, which is convenient for installation and disassembly. During the dust suppression process, water droplets generated by insufficient atomization of water mist or water mist detaching from the inner wall of the dust suppression cylinder fall into the collection box together, avoiding water droplet pollution to the ground and waste of water resources. The metal material and magnetic adsorption design of the collection box also facilitate regular cleaning and replacement, keeping the dust suppression device clean and operating efficiently.

[0023] Furthermore, the water supply mechanism 5 includes a water tank 501 fixedly connected to one end of the body 1. A water inlet pipe 502 is fixedly connected to the top of the water tank 501, facilitating the addition of water to the tank and the collection box 302. A water pump 503 is fixedly connected inside the body 1. A suction pipe 504 is fixedly connected to one end of the pump 503, and an output pipe 505 is fixedly connected to the top of the pump 503. An atomizing nozzle 506 is fixedly connected to the top of the output pipe 505, located inside the dust collection cylinder 2. The suction pipe 504 communicates with the water tank 501. The top of the output pipe 505 is fixedly connected to the inside of the dust collection cylinder 2, and the bottom is movably connected to the inside of the rotating disk 402. The bottom of the output pipe 505 is a flexible hose, which allows the rotating disk 402 to stretch or deform during rotation, thus facilitating its operation.

[0024] The water supply tank 501 in the water supply mechanism 5 stores the water needed for dust suppression. The water pump 503 draws water from the water supply tank 501 through the water pumping pipe 504 and delivers it to the atomizing nozzle 506 for atomized spraying through the output pipe 505. This design realizes the recycling of water resources, reduces water waste, and at the same time, the fine water mist generated by the atomizing nozzle can more effectively adsorb dust, improve the dust suppression effect, and further save water resources.

[0025] The working principle of the above embodiments is as follows: (1) The dust suppression device for coal yards generates a strong airflow through the fan 201, which blows the water mist sprayed by the atomizing nozzle 506 to every corner of the coal yard, effectively adsorbing and settling dust particles in the air. At the same time, the motor 401 in the transmission mechanism 4 drives the rotating disk 402 to rotate, which drives the dust suppression cylinder 2 to rotate in the horizontal direction. The electric push rod 404 adjusts the pitch angle of the dust suppression cylinder 2, realizing flexible adjustment of the dust suppression angle and range, which greatly improves the dust suppression efficiency.

[0026] (2) The dust suppression device for coal yards has a cleverly designed support plate 301 and collection box 302 in the collection mechanism 3. The collection box 302 is attached to the top of the support plate 301 by a magnet, which is convenient for installation and disassembly. During the dust suppression process, water droplets generated by insufficient atomization of water mist or water mist disintegrating with the inner wall of the dust suppression cylinder fall into the collection box together, avoiding water droplet pollution of the ground and waste of water resources. The metal material and magnetic adsorption design of the collection box are also convenient for regular cleaning and replacement, keeping the dust suppression device clean and efficient.
