[0001] The utility model relates to the technical field of mine environmental protection, in particular to a dust reduction device for mine exploitation. Background Art

[0002] A large amount of dust will be generated during the process of mine exploitation. These dusts will not only cause workers to suffer from respiratory diseases and affect their physical health, but may also trigger safety accidents such as explosions.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a dust reduction device for mine exploitation, including a water storage tank 1, and a water inlet 15 is provided on the water storage tank 1.

[0027] Furthermore, the water inlet 15 on the water storage tank 1 facilitates replenishing water into the tank at any time, ensuring that the dust reduction device can work continuously and stably, avoiding the interruption of the dust reduction operation due to water shortage, and ensuring the continuity of the dust reduction effect.

[0028] As Figure 1 and Figure 4 shown, a spraying mechanism is provided above the water storage tank 1. The spraying mechanism includes a support bolt 2, a water supply pipe 3 is fixed at the top of the support bolt 2, a plurality of horizontally extending water pipes 4 are fixed on the water supply pipe 3, a plurality of atomizing nozzles 5 are fixed on the horizontally extending water pipes 4, an L-shaped channel 6 is provided in the support bolt 2, and a spirally telescopic water pipe 7 communicated with the L-shaped channel 6 is fixed on the water storage tank 1.

[0029] Furthermore, in the spraying mechanism, the atomizing nozzles 5 can spray water mist at different heights and angles, covering the mine exploitation area in a large area and all-round manner, efficiently adsorbing dust in the air, significantly reducing the dust concentration, and creating a healthier working environment for workers.

[0030] As Figure 1 shown, a water pump 17 is provided at the bottom inside the water storage tank 1, and the water outlet end of the water pump 17 is connected and communicated with the spirally telescopic water pipe 7.

[0031] Furthermore, the spirally telescopic water pipe 7 can be stretched and spirally contracted to adapt to the height of the support bolt 2.

[0032] As Figure 4 shown, the plurality of horizontally extending water pipes 4 are evenly divided into two groups and symmetrically arranged on both sides of the water supply pipe 3, and the distance between two adjacent atomizing nozzles 5 on the same side is the same.

[0033] Furthermore, this can ensure that the water mist sprayed by the atomizing nozzles 5 can be evenly sprayed, improving the dust reduction effect.

[0034] As Figure 1 shown, the included angle formed between the water supply pipe 3 and the support bolt 2 is any value within the range of 90° to 180°.

[0035] Furthermore, this angle design can enable the water mist to better cover the mine mining area and enhance the dust suppression effect.

[0036] As Figure 1 shown, the water storage tank 1 and the spraying mechanism are connected through a lifting mechanism; the lifting mechanism includes a fixed cylinder 8 fixed on the water storage tank 1, the outer side wall of the support bolt 2 is slidably connected with the inside of the fixed cylinder 8, a cylinder 9 is fixed at the bottom inside the fixed cylinder 8, and the piston end of the cylinder 9 is fixedly connected with the bottom of the support bolt 2.

[0037] Furthermore, the overall design of the device is flexible, and the height of the spraying mechanism can be adjusted through the lifting mechanism, so as to adapt to different mining scenarios and operating conditions and meet diverse dust suppression requirements.

[0038] As Figure 1 shown, a sliding opening 18 is provided on the fixed cylinder 8.

[0039] Furthermore, the purpose of setting the sliding opening 18 is to facilitate the movement of the coiled retractable water pipe 7.

[0040] As Figure 1 and Figure 5 shown, the water supply pipe 3 and the support bolt 2 are connected through a quick-disassembly mechanism. The quick-disassembly mechanism includes an installation groove 10 opened at the top of the support bolt 2, an insertion pipe 11 communicated with the L-shaped channel 6 is fixed at the bottom inside the installation groove 10, an installation sleeve 12 is fixed at the bottom end of the water supply pipe 3, the inner side wall of the installation sleeve 12 is slidably connected with the outer side wall of the insertion pipe 11, and the top of the installation sleeve 12 and the support bolt 2 are connected through a plurality of fixing bolts.

[0041] Furthermore, the quick-disassembly mechanism between the water supply pipe 3 and the support bolt 2 enables the water supply pipe 3 and the atomizing nozzle 5 thereon to be quickly disassembled when a failure occurs for separate repair or replacement, without the need to perform large-scale disassembly on the entire spraying mechanism, saving maintenance time and cost.

[0042] As Figure 1 shown, a ladder 16 is fixed on the top of the water storage tank 1.

[0043] Furthermore, the ladder 16 on the top of the water storage tank 1 can facilitate workers to perform operations such as inspection, maintenance, and cleaning on the top of the water storage tank 1 and other related components, and can provide a convenient support platform for the disassembly of the water supply pipe 3.

[0044] As Figure 1As shown in the figure, a moving mechanism is provided at the bottom of the water storage tank 1. The moving mechanism includes a moving platform 13 fixed to the bottom of the water storage tank 1, and a plurality of moving wheels 14 are fixed to the bottom of the moving platform 13.

[0045] Furthermore, the combination of the moving platform 13 and the moving wheels 14 enables the dust suppression device to quickly move to various working locations in the mine. Without a complex installation and commissioning process, it can be put into use in a short time to promptly respond to dust pollution situations in different areas, improving the response speed and working efficiency of the device.

[0046] The functional principle of the present utility model can be elaborated through the following operation methods:

[0047] I. Preparation stage

[0048] Adding water

[0049] Add an appropriate amount of water to the water storage tank 1 through the water inlet 15 on the water storage tank 1. A water pipe can be used to connect to the water source for water injection, ensuring the cleanliness of the water and avoiding blockage of the atomizing nozzle 5 by impurities.

[0050] II. Movement and positioning stage

[0051] Moving the device

[0052] Push or drive (if it is an electric or mechanical drive moving platform 13) the dust suppression device to the mine area where dust suppression operations need to be carried out. Utilize the moving wheels 14 at the bottom of the moving platform 13 to select an appropriate path and method according to the actual situation to move the device to the target position.

[0053] Positioning the device

[0054] After reaching the designated position, determine the optimal placement position of the dust suppression device according to the terrain of the mine exploitation site, the height of the working surface, and the dust distribution situation. Ensure that the device will not be interfered by other equipment or obstacles during the working process, and at the same time can effectively cover the dust generation area.

[0055] III. Adjusting the spray mechanism stage

[0056] Adjusting the height

[0057] If it is necessary to adjust the height of the spray mechanism, the user can operate the lifting mechanism. By controlling the expansion and contraction of the cylinder 9, the support bolt 2 slides up and down in the fixed cylinder 8, thereby adjusting the water delivery pipe 3 and the atomizing nozzle 5 to an appropriate height. For example, for a higher working surface, raise the spray mechanism; for a wider working area, appropriately lower the height of the spray mechanism to increase the water mist coverage area.

[0058] IV. Starting the dust suppression device stage

[0059] Turning on the spray

[0060] After confirming that the position, height, and angle of the device are adjusted properly, the user turns on the water pump 17. Water is pumped by the water pump 17 from the water storage tank 1 through the coiled retractable water pipe 7 into the L-shaped channel of the support bolt 2, then transported to the water delivery pipe 3 and the laterally extending water pipe 4, and finally sprayed out from the atomizing nozzle 5 to form a water mist for dust suppression operations.

[0061] V. Maintenance and Shutdown Phases

[0062] Equipment Maintenance

[0063] After the dust suppression operation is completed or the equipment has been running for some time, the user needs to maintain the device. The user can climb to the top of the water storage tank 1 through the ladder 16 on the top of the water storage tank 1 to inspect and clean components such as the spraying mechanism and water pipes. If the water delivery pipe 3 or the atomizing nozzle 5 fails, it can be disassembled using the quick-disassembly mechanism for repair or replacement.

[0064] Shutting Down the Device

[0065] When the dust suppression device is not needed, the user first turns off the water pump 17 and then moves the device to a suitable storage location.

[0066] Through the above steps, the user can effectively operate the mine dust suppression device to achieve the purpose of dust suppression during the mine mining process and protect the health of workers and environmental safety.

[0067] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
