Abstract
The utility model discloses a high-pressure water jet pneumatic negative pressure drilling dust removal device, which is characterized by comprising a wind-guiding slag separator (1), a drilling dedusting protective cover (2), a skeleton type airway tube (3) and a dedusting barrel (4) connected in sequence, wherein the dedusting barrel (4) comprises an outer cover (5) and a spray head (6) mounted in the outer cover (5) as well as a static pressure water supply pipe (7) connected onto the spray head (6), a compressed air supply pipe and a jet device (8); and the skeleton type airway tube (3) is connected with the spray head (6). According to the utility model, the high-pressure water jet pneumatic negative pressure drilling dust removal device utilizes the negative pressure to separate dust from drilling slag in different ways and eliminates dust in the dedusting barrel, so as to effectively and quickly prevent drilling dust from diffusing and protect staff against the damage of high-concentration dust.
Description
Technical field
The utility model relates to the pneumatic negative pressure drilling dust-removing apparatus of a kind of high-pressure water jet, dedusting when being mainly used in coal bed drilling work, and the dust that prevents from holing diffusion, the Protection personnel avoid the high concentrate dust infringement.
Background technology
The colliery downhole powder dust refers to the fine coal dust that produces and the general name of rock dirt in coal production.The colliery downhole powder dust has following characteristic: dust adsorption one deck air film, hinder between dust or the flocking settling between water droplet and dust; The decentralization of dust increases, and is adsorbed on its surperficial oxygen molecule and increases, and has accelerated the dust oxidation decomposition course; Trickle rock dirt is because surface area increases, and the free silicon dioxide in the rock dirt dissolves readily in the Human Lung cell; The fresh dust that getting working face produces is easily charged than the dust in the air-return duct.Because dust has these characteristics and has determined following harm: easily cause pneumoconiosis; Easily cause burning and blast; High concentrate dust can wear and tear by acceleration mechanical, shortens the application life of precision instrument.
Down-hole coal excavation, driving, reprinting, transportation all can produce a large amount of dust; the severe contamination subsurface environment; when coal bed drilling was worked, owing to there not being suitable cleaner, single dependence coal mining personnel wore mouth mask or mask; because the Dust Capacity concentration short time can't disappear; therefore, mouth mask and mask all can not really be protected coal mining personnel's breathing safety, so coal bed drilling when work; need a kind of high effect dust cleaner, but have no report in the prior art.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model provides a kind of pneumatic negative pressure drilling dust-removing apparatus of high-pressure water jet of energy high-effective dust-removing.
For achieving the above object, the technological means of employing described in the utility model is: the pneumatic negative pressure drilling dust-removing apparatus of a kind of high-pressure water jet, comprise and connect successively wind-guiding scummer, boring dedusting protective cover, skeleton wireway, dust removing drum, described dust removing drum comprises outer cover and is installed in the fog-spray nozzle in the outer cover and is connected to static pressure feed pipe, compressed air air supply pipe and ejector on the fog-spray nozzle, and described skeleton wireway connects described fog-spray nozzle.
Operating principle: under the dust removing drum effect, make boring dedusting protective cover place form negative pressure, air then enters boring dedusting protective cover by the wind-guiding scummer, the dust that forms during with boring sucks skeleton wireway, mix the dirt that goes out through the fog-spray nozzle in the dust removing drum, the boring slag is because gravity falls within ground through the wind-guiding scummer, and the dust that prevents from holing spreads.
The beneficial effects of the utility model are: utilize negative pressure that dust is separated from different approach with the boring slag, and the dirt that in dust removing drum, goes out, fast efficient, the dust that prevents from holing diffusion, the Protection personnel avoid the high concentrate dust infringement.
Description of drawings
Below in conjunction with accompanying drawing the technical solution of the utility model is described.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, wind-guiding scummer, 2, boring dedusting protective cover, 3, skeleton wireway, 4, dust removing drum, 5, outer cover, 6, fog-spray nozzle, 7, the static pressure feed pipe, 8, compressed air air supply pipe and ejector.
The specific embodiment
The pneumatic negative pressure drilling dust-removing apparatus of a kind of high-pressure water jet as shown in Figure 1, comprise and connect successively wind-guiding scummer 1, boring dedusting protective cover 2, skeleton wireway 3, dust removing drum 4, described dust removing drum 4 comprises outer cover 5 and is installed in the fog-spray nozzle 6 in the outer cover 5 and is connected to static pressure feed pipe 7, compressed air air supply pipe and ejector 8 on the fog-spray nozzle 6, and described skeleton wireway 3 connects described fog-spray nozzle 6.
Under dust removing drum 4 effects, make boring dedusting protective cover 2 places form negative pressure, air then enters boring dedusting protective cover 2 by wind-guiding scummer 1, the dust that forms during with boring sucks skeleton wireway 3, mix the dirt that goes out through the fog-spray nozzle 6 in the dust removing drum 4, the boring slag is because gravity falls within ground through wind-guiding scummer 1, and the dust that prevents from holing spreads.
