Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression equipment, in particular to a dust suppression device for a mine tunnel. Background Art

[0002] During the construction of mine tunnels, dust pollution has always been an important issue affecting the working environment and workers' health.

[0003] Traditional dust removal equipment generally adopts a single spray or mechanical filtration method, which has defects such as low dust removal efficiency, easy filter clogging, and frequent maintenance. Especially in a high-concentration dust environment, ordinary sprays are difficult to completely capture fine particles, and mechanical filtration devices are prone to increased wind resistance due to dust accumulation, seriously affecting the normal operation of the equipment. In addition, the equipment lacks an effective self-cleaning function and requires frequent shutdowns for maintenance, which not only increases the cost of use, but also affects the construction progress.

[0004] For this reason, we propose a dust suppression device for mine tunnels to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a dust suppression device for a mine tunnel to solve the above-mentioned technical deficiencies.

[0011] Preferably, support seats are installed on the outer walls of both sides of the dust removal cylinder through supporting plates.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] The first annular tube sprays fine water mist into the airflow through an atomizing nozzle, so that the dust particles are fully in contact with the water mist and increase weight and settle.

[0023] Embodiment 1

[0024] Refer to the instruction manual Figure 1-4 A dust suppression device for a mine tunnel comprises a dust removal cylinder 1, the interior of which is divided into an atomizing chamber and a cleaning chamber by a filter cotton net 3 fixedly installed by a positioning ring 2. In the atomizing chamber, a first annular tube 4 is arranged along the inner wall, and atomizing nozzles 5 are evenly distributed thereon. A dust suppression liquid supply system is externally connected through a first liquid inlet pipe 8, so that the dust suppression liquid is evenly sprayed in the dust-containing air flow after atomization. A second annular tube 6 installed on the side wall of the cleaning chamber is connected to the cleaning liquid supply system through a second liquid inlet pipe 9. A spray head 7 sprays cleaning liquid toward the filter cotton net 3 in a directional manner to maintain the permeability of the filter net. A honeycomb air intake plate 11 is embedded in the fixing ring 10 on the inner wall at one end of the dust collector 1, and its porous structure is used to guide the dust-laden airflow to evenly enter the atomization chamber to avoid direct impact on the filter. A plurality of exhaust sleeves 13 are installed on the back plate 12 on the inner wall at the other end, and a built-in exhaust fan 14 forms a negative pressure environment to accelerate the airflow through the device. The drainage pipes 15 at the bottom of the atomization chamber and the cleaning chamber converge into the water guide pipe 16, and an external waste liquid collection system is connected to realize circulation treatment. The support seats 17 are fixed on both sides of the dust collector 1 by support plates, which facilitates the installation of the utility model at a designated position.

[0025] Implementation II

[0026] Based on the first embodiment, a fixing ring 10 is added to the end of the atomizing chamber of the dust collector 1 to install a honeycomb air inlet plate 11 to stabilize the airflow, an exhaust sleeve 13 with an exhaust fan 14 is installed on the back plate 12 to form negative pressure suction, and the support seat 17 fixes the dust collector 1 through a supporting plate. The atomizing nozzle 5 and the spray head 7 are arranged in a ring shape, and the sewage generated by the atomizing chamber and the cleaning chamber are combined and discharged through the water pipe 16.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-4 In the mine, the dust-laden airflow is sucked by the exhaust fan 14 and evenly enters the atomizing chamber of the dust collecting tube 1 through the honeycomb air intake plate 11. The first annular tube 4 sprays fine water mist into the airflow through the atomizing nozzle 5, so that the dust particles are fully in contact with the water mist and increase weight and settle. The initially purified air then penetrates the filter cotton net 3 and enters the cleaning chamber. The filter cotton net 3 further intercepts the remaining fine dust. At this time, the second annular tube 6 continuously reversely flushes the filter cotton net 3 through the spray head 7 to prevent dust accumulation and blockage. The flushed sewage and the muddy water settled in the atomizing chamber are respectively collected into the water guide pipe through their respective drainage pipes 15. 16 is discharged uniformly, and the purified air is discharged from the device through the exhaust sleeve 13 under the push of the exhaust fan 14. During the whole process, the first liquid inlet pipe 8 and the second liquid inlet pipe 9 continuously provide water to the atomization system and the flushing system respectively. The support seat 17 is convenient for installing the utility model in a specified position. After the filter cotton net 3 has been used for a period of time, the detachable positioning ring 2 can be replaced and maintained, and the quick-release connection design of the annular tube and the inlet and outlet water pipelines is convenient for rapid maintenance and component replacement of the equipment. Through the synergistic effect of atomization dust suppression, filtration interception and automatic flushing, efficient and continuous dust suppression in the working environment of the mine tunnel is achieved.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
