Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression for mining machines, in particular to a dry mist dust suppression component applied to mining machines. Background Art

[0002] While the widespread use of mining machines in the mining industry has greatly improved mining efficiency, it has also led to serious dust pollution. During mining operations, such as cutting, crushing, and loading, mining machines disturb large quantities of ore, coal, and other materials, generating large amounts of dust of varying particle sizes. This dust permeates the mining site, posing multiple hazards to the environment and human health.

[0003] During deep hole excavation, the crushing action of the drill bit on media such as rock and soil generates a large amount of dust. To reduce the dust hazards generated during deep hole excavation, traditional dust suppression methods include sprinkling water to reduce dust. However, sprinkling water to reduce dust has some limitations. First, the water droplets formed by sprinkling water are large in size, which is not effective for capturing smaller dust particles, and can only cause some large dust particles to settle. Second, large amounts of water sprinkling can easily cause water accumulation at the work site, especially in deep holes. Water accumulation can affect the normal progress of excavation operations and may also cause problems such as rusting of equipment. Therefore, a dry mist dust suppression component for use in mining machines is now proposed. Utility Model Content

[0004] The purpose of this utility model is to solve some limitations of existing traditional dust suppression methods, such as poor capture effect on dust with smaller particle size, only settling of some large dust particles, and large amount of water sprinkling easily causing water accumulation at the work site, especially water accumulation in deep holes, which will affect the normal progress of excavation operations and may also cause equipment to rust and other problems. A dry mist dust suppression component for use in mining machines is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A dry fog dust suppression component for use in a mining machine comprises a mining machine body, a water tank being arranged inside the mining machine body, a water pump being arranged at the upper and lower ends of the inner wall of the water tank, the water outlet end of the water pump being connected to a water pipe, one end of the water pipe being connected to a rectangular water outlet pipe, the outer wall of the rectangular water outlet pipe being provided with evenly distributed gas-liquid two-phase nozzles, and a water injection component being arranged at the top of the mining machine body.

[0007] Preferably, a connecting pipe is connected through the outer wall of the rectangular water outlet pipe, and the connecting pipe is slidably connected to the water pipe.

[0008] Preferably, a mounting groove is provided on the outer wall of the mining machine body, and evenly distributed hidden grooves are provided on the outer walls on both sides of the mounting groove, and threaded holes are provided at the bottom ends of the inner walls of the hidden grooves.

[0009] Preferably, the rectangular water outlet pipe is clamped with the installation groove, and the outer wall of the rectangular water outlet pipe is fixedly connected with a connecting plate, and the connecting plate is threadedly connected with bolts.

[0010] Preferably, the water injection assembly includes a sealing door, a notch, and a connecting port. The sealing door is connected to the top outer wall of the mining machine body through a hinge. The notch is arranged at the top of the mining machine body, and the connecting port is arranged at the inner bottom end of the notch.

[0011] Preferably, the sealing door is slidably connected to the notch, and the connecting port is through-connected to the water tank.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the utility model is in use, the rectangular water outlet pipe and the gas-liquid two-phase nozzle arranged behind the excavator head can be used to transport the water in the water tank to the rectangular water outlet pipe through the water pump, and then sprayed out through the gas-liquid two-phase nozzle to suppress the dust, thereby saving more space, achieving better dust capture effect, using less water, and not generating a large amount of accumulated water.

[0021] It should be noted that the mining machine body 1, water pump 3, and gas-liquid two-phase nozzle 6 are existing technologies. The specific model specifications need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0022] Furthermore, a connecting pipe 8 is connected through the outer wall of the rectangular water outlet pipe 5 , and the connecting pipe 8 is slidably connected to the water pipe 4 .

[0023] Among them, the diameter of the connecting pipe 8 is smaller than the diameter of the water pipe 4, so that the connecting pipe 8 can be inserted into the water pipe 4 along the way. One end of the connecting pipe 8 is provided with an inwardly concave bevel, which can better guide the water flow into the rectangular water outlet pipe 5.

[0024] Furthermore, a mounting groove 13 is provided on the outer wall of the mining machine body 1 , and evenly distributed hidden grooves 9 are provided on the outer walls on both sides of the mounting groove 13 , and threaded holes 10 are provided at the bottom ends of the inner walls of the hidden grooves 9 .

[0025] Among them, the size of the installation groove 13 is adapted to the size of the rectangular water outlet pipe 5. The rectangular water outlet pipe 5 is composed of two U-shaped parts. When installing the rectangular water outlet pipe 5, the rectangular water outlet pipes 5 are first assembled together and then inserted into the installation groove 13.

[0026] Furthermore, the rectangular water outlet pipe 5 is clamped with the installation groove 13 , and the outer wall of the rectangular water outlet pipe 5 is fixedly connected with a connecting plate 11 , and the connecting plate 11 is threadedly connected with a bolt 12 .

[0027] Among them, the connecting plate 11 is slidably connected to the hidden groove 9, and the bolt 12 passes through the connecting plate 11 and is connected to the threaded hole 10, so that the rectangular water outlet pipe 5 can be installed more stably and occupies a smaller area.
