Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a wind and water linkage spray device in the coal mining process. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During the coal mining process, a large amount of dust will be generated. The usual protection method is to use water spray to reduce the dust. The wind and water linkage atomizing spray uses compressed air as the power to accelerate the water flow to the atomizing nozzle for atomization and spraying.

[0003] Although some of the current atomizing nozzles use compressed air as power to spray water mist, the compressed air has a large impact force, which carries the water mist with it and causes the water mist spray shape to tend to be linear. Although the spraying distance is far, there is still room for improvement in the diffusion range of the water mist. Utility Model Content

[0004] The purpose of the utility model is to provide a wind and water linkage spray device in the coal mining process to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wind and water linkage spray device for a coal mining process comprises an air blast structure, a wind and water pipe is rotatably mounted on the bottom of the air blast structure, a wind and water linkage spray head is fixedly mounted on the bottom side of the wind and water pipe, and the number of the wind and water linkage spray heads is several. The air blast structure comprises an air guide hood, a fan is fixedly mounted at a small opening on the top of the air guide hood, an annular groove is provided on the bottom side of a large opening at the bottom of the air guide hood, a motor is fixedly mounted on an outer wall on one side of the large opening at the bottom of the air guide hood, the air blast pipe comprises a connecting ring, a retaining ring is fixedly mounted on the upper surface of the connecting ring, an outer toothed ring is fixedly sleeved on the outer surface of the connecting ring, the outer toothed ring is meshed with a gear, the retaining ring is rotatably engaged with the annular groove, and the gear is fixedly mounted on the output end of the motor.

[0007] The invention further comprises that an air pipe protrusion groove is interspersed on the side wall of the large opening at the bottom of the air guide cover.

[0008] Furthermore, the Feng Shui pipeline includes a base block, a wind chamber is opened on the upper side of the base block, an inflation pipeline is connected to the upper side of the wind chamber through a sealing bearing, four air distribution pipes are connected to the side surface of the wind chamber in a circular shape with equal angles, a water chamber is opened on the lower side of the base block, a water injection pipeline is connected to the bottom of the water chamber through a sealing bearing, and four water distribution pipes are connected to the side surface of the water chamber in a circular shape with equal angles.

[0009] Furthermore, the four groups of gas distribution pipes and water distribution pipes are fixedly connected at equal angles in a ring shape on the side surface of the base block, and the outer ends are fixedly connected with connecting rings.

[0010] Furthermore, the wind and water linkage spray head comprises an air jet pipe, one side of the air jet pipe is fixedly connected to a water pipe, and an atomizing nozzle is fixedly installed at the lower end of the air jet pipe.

[0011] Furthermore, the plurality of air jet pipes are arranged in a linear array at the bottom of the air distribution pipe and are interconnected with the air distribution pipe.

[0012] Furthermore, the plurality of water delivery pipes are arranged in a linear array at the bottom of the water distribution pipe and are interconnected with the water distribution pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The air supply structure and the water supply structure are connected through the Fengshui pipeline, and the air and water are sprayed out from the Fengshui linkage spray head in atomized form. While spraying, the gear is rotated by the motor, and then the connecting ring is rubbed by the outer gear ring to drive the Fengshui pipeline to rotate while spraying through the Fengshui linkage spray head, thereby increasing the spraying range of the water mist. At the same time, the fan is started to generate airflow, and blown to the spray area under the guidance of the guide wind hood. The airflow is used to carry the water mist and blow it into the coal mine heading. The airflow increases the diffusion range of the water mist and improves the dust reduction effect.

[0015] 2. The high-pressure airflow in the gas distribution pipe will pass through the water delivery pipe to quickly push the water introduced into the jet pipe from the water distribution pipe to the atomizing nozzle for atomization and spraying. Before spraying, the water and gas are linked to avoid premature mixing of water and gas, which will lead to intermittent water output during pipeline transportation.
