Abstract
The invention provides a belt lower coal dust removal device, which comprises a roller; the roller support is supported on the roller support through a rotating shaft, the roller support is further provided with a dust removal support, and the dust removal support is provided with a scraper and a spray head. According to the invention, the spraying device is additionally arranged at the upper end of the belt at the blanking position, so that water mist and dust fall down after being combined, and dust pollution is reduced.
Description
Technical Field
The invention relates to a belt lower coal dust removing device.
Background
in dry weather, coal extracted from a mine is dry as well, the cut coal always has dust, and the dust can be raised when wind blows or blanking is carried out, so that the sight of workers in a coal yard is influenced, and the pollution to the bodies of the workers is great.
Disclosure of Invention
In order to solve the technical problem, the invention provides a belt lower coal dust removal device.
The invention is realized by the following technical scheme.
The invention provides a belt lower coal dust removal device, which comprises a roller; the dust removing device is supported on a roller bracket through a rotating shaft, the roller bracket is also provided with a dust removing bracket, and the dust removing bracket is provided with a scraper and a spray head.
The scraper is arranged at the lower end of the roller, and the distance between the scraper and the roller is the range from the roller support to the water inlet mm.
The spray head is arranged at the upper end of the roller and is connected with a water pipe fixed in the dust removal bracket.
The shower nozzle evenly sets up to a plurality ofly on dust removal support, the opening of shower nozzle is vertical upwards.
The dust removal support is fixedly connected to the upper end and the lower end of the roller support, grooves are machined in the direction of the dust removal support, the spray head and the scraper are installed in the grooves in the dust removal support, and the grooves in the spray head are also internally provided with cleaning devices.
The cleaning device is U-shaped and is clamped on the groove wall of the groove.
The invention has the beneficial effects that: by adding the spraying device at the upper end of the belt at the blanking position, the water mist and the dust fall after being combined, and the dust pollution is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
In the figure: 1-roller, 2-roller bracket, 3-dedusting bracket, 4-scraper, 5-water inlet, 6-rotating shaft and 7-spray head.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A belt lower coal dust-removing device comprises a roller 1; the dust removing device is supported on the roller bracket 2 through a rotating shaft 6, the roller bracket 2 is also provided with a dust removing bracket 3, and the dust removing bracket 3 is provided with a scraping plate 4 and a spray head 7.
The scraper 4 is arranged at the lower end of the roller 1, and the distance between the scraper 4 and the roller 1 is 2-5 mm of the roller bracket.
The spray head 7 is arranged at the upper end of the roller 1, and the spray head 7 is connected with a water pipe fixed in the dust removal bracket 3.
The plurality of spray heads 7 are uniformly arranged on the dust removing support 3, and the openings of the spray heads 7 are vertically upward. The shower nozzle is not direct to spray the coal on the belt, prevents that the coal on the belt from absorbing water too much and attaching to on the belt, influences the operation of belt to upwards spray, make the scope of water smoke bigger, the effect of preventing the dust is better.
The dust removal support 3 is fixedly connected to the upper end and the lower end of the roller support 2, grooves are processed in the direction of the dust removal support 3, the spray head 7 and the scraper 4 are both installed in the grooves in the dust removal support 3, and the grooves in the spray head 7 are also provided with cleaning devices.
The cleaning device is U-shaped and is clamped on the groove wall of the groove. The U-shaped card slides on the groove wall to remove accumulated dust in the groove and prevent the spray head from being blocked by excessive dust.
