Embodiment Construction
[0026] refer to figure 1 , figure 1 Schematic diagram of the structure of the negative pressure drilling dust removal device provided by the embodiment of the present invention.
[0027] Such as figure 1 As shown, the negative pressure drilling dust removal device provided in this embodiment includes a dust catcher 1 for absorbing dust in the space, a negative pressure chamber 2 for providing negative pressure for the dust catcher 1 and a dust collector for filtering dust Bin 3; dust catcher 1 communicates with negative pressure bin 2, and negative pressure bin 2 communicates with dust removal bin 3. In order to improve the ability of the dust catcher 1 to absorb dust, on the one hand, it is necessary to improve the suction capacity of the negative pressure chamber 2, and a negative pressure fan can be installed in the negative pressure chamber 2; The cross-section of the dust port to improve the ability to absorb dust.
[0028] The dust removal bin 3 is provided with a fi...

The invention provides a negative pressure drilling dust removal device, which comprises a dust catcher for absorbing dust in a space, a negative pressure bin for providing negative pressure for the dust catcher and a dust removal bin for filtering dust. The dust catcher is communicated with the negative pressure bin, and the negative pressure bin is communicated with the dust removal bin; and a filter screen for filtering dust and a plurality of spray heads are arranged in the dust removal bin, the dust removal bin is partitioned into a filter bin and a purification bin by the filter screen, and the filter bin is close to the negative pressure bin. Through the negative pressure drilling dust removal device, the dust is absorbed by the dust catcher communicated with the negative pressure bin, and the dust is filtered and purified for many times through the filter screen and a plurality of spray heads arranged in the dust removal bin, so that the quantity of the dust in a roadway can be effectively reduced, the operating safety of a coal mine is improved, and harm to body health of operating workers due to the dust is reduced.
Description
technical field [0001] The invention relates to the coal mine underground drilling dust removal technology, in particular to a negative pressure drilling dust removal device. Background technique [0002] During the drilling process of underground coal mine construction, the slag generated during drilling is discharged through the compressed air, and the tiny coal (rock) dust particles generated during the drilling construction process will be discharged in the state of floating particles, resulting in Coal (rock) dust is flying in the front and rear, and the visibility on the site is low, which brings safety hazards to coal mine production. At the same time, the dust causes great harm to the health of on-site workers. [0003] The existing dust removal device is orifice spray dust removal, most of which are single-hole spray devices, which reduce the dust concentration on the site through spraying operations. Because the spray volume of the single-hole spray device is small...
