Abstract
The utility model discloses an open-close type blowout prevention hole composite dust hood which comprises a dust hood body. The dust hood body consists of an upper cover body and a lower cover body; one sides of the upper cover body and the lower cover body are connected by a hinge pin and the other sides of the upper cover body and the lower cover body are locked and sealed by a rapid hasp; the upper part of the upper cover body is provided with a dust collection passage; the lower part of the lower cover body is provided with a dust discharge port; the front end of the dust hood body is provided with a pipeline leading to a coal hole; the pipeline is connected with a rapid clamping steel ring; the inside and the outer wall of the dust hood body are at least provided with two perforated steel plates capable of allowing drill rods to penetrate through; and perforated axes of the steel plates are consistent with the axis of the pipeline communicated to the coal hole. The design of the open-close type blowout prevention hole composite dust hood provides great convenience for rapidly installation and disassembly of the dust hood at an underground narrow orifice, improves working efficiency, and not only ensures that all dust and gas are totally collected, but also can reasonably treat the dust and the gas respectively; and meanwhile, the air return condition in a drilled hole is observed by large coal granules falling from the lower end of the dust hood so as to determine whether the conditions of hole collapse and hole blockage are generated, so as to timely carry out treatment and ensure safety production of the drilled gas hole.
Description
Technical field
The utility model relates to a kind of deduster, specifically the anti-compound dust shield of spray orifice of a kind of opening-closing type.
Background technology
At present, coal holds an important position in the national economy energy resource structure, and along with development and national economy, the demand of coal is also increasing, when raw coal output increases fast, also must guarantee the safety and high efficiency of mine.Mine gas is in the coal mining now, need hole in the coal seam usually, because the coal seam drying, coal dust flies upward when boring, also be mingled with gas simultaneously, causing great injury for operator's health, coming a lot of unsafe factors also for the colliery safety belt.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes the anti-compound dust shield of spray orifice of a kind of opening-closing type, thereby prevents that effectively coal dust and gas from gushing out in the hole in a large number.
In order to solve above technical problem, the utility model provides a kind of opening-closing type to prevent the compound dust shield of spray orifice, comprises the dust shield body, and described dust shield body is made up of upper cover body and lower cover, a side is connected by pivot pin between described upper cover body and the lower cover, and opposite side is by quick hasp lock tightening seal; Described upper cover body top is provided with dust absorption passage, and described lower cover bottom is provided with the dust outlet opening; The front end of described dust suction cover body is provided with the pipeline that leads to the coal hole, is connected with fast steel-fastening circle on the described pipeline; Described dust shield body interior and outer wall arrange the perforate steel plate that twice can be by drilling rod at least, and the bore axis of described steel plate is consistent with the described conduit axis that leads to the coal hole.
The utility model further limits technical scheme: aforesaid opening-closing type is prevented the compound dust shield of spray orifice, accompanies the silicone rubber seal pad in the middle of the described perforate steel plate drilling rod is sealed.
Further, aforesaid opening-closing type is prevented the compound dust shield of spray orifice, and the described pipe lining that leads to the coal hole has the H62 copper coin, and the other end of pipeline puts in the brill coal hole of holding successfully in advance, can accomplish with the sealing of junction, coal hole air tight.
With existing equipment earlier than, the utility model design has greatly made things convenient for Fast Installation and the dismounting of place, narrow aperture, down-hole dust shield, improved operating efficiency, both guaranteed that whole dust and gas were collected fully, can distinguish again rationally and to dispose, the large coal particles grain situation that falls by the dust shield lower end is observed return air situation in the boring simultaneously, with the situation of determine whether to collapse hole, plug-hole, the safety in production in gas hole so that disposal in time, assurance are drilled.Even slight gas spray orifice is arranged, dust shield also can decompose easily, dispose, and guarantees safety in production.

The specific embodiment
Embodiment 1
A kind of opening-closing type that present embodiment provides is prevented the compound dust shield of spray orifice, structure comprises dust shield body 1 as depicted in figs. 1 and 2, and the dust shield body is made up of upper cover body 2 and lower cover 3, a side is connected by pivot pin 4 between upper cover body and the lower cover, and opposite side is by quick hasp 5 lock sealings; Upper cover body top is provided with dust absorption passage 6, and the lower cover bottom is provided with dust outlet opening 7; The front end of dust suction cover body is provided with the pipeline 8 that leads to the coal hole, and pipeline is long to be 100mm, and internal diameter is Φ 125mm, and pipe lining has the H62 copper coin, is connected with fast steel-fastening circle 9 on the pipeline; Dust shield body interior and outer wall arrange twice at least and can accompany 11 pairs of drilling rods of silicone rubber seal pad in the middle of the steel plate and seal by the perforate steel plate 10 of drilling rod, and the bore axis of steel plate is consistent with the conduit axis that leads to the coal hole.
Present embodiment in use, the pipeline that will serve as a contrast H62 copper earlier inserts the boring of having held successfully, then drilling rod is stretched into and insert the coal seam in the dust shield, again the dust shield upper cover body is opened along pivot pin, drilling rod is encased the quick hasp of closed and locked dust shield afterwards, with quick steel card dust shield is connected with dust leg at last and finishes; The coal dust bulky grain natural mouth of pipe from the dust shield lower end under the effect of gravity that enters in the dust shield falls earthward, the negative pressure that tiny dust and the methane gas upper orifice by dust shield is produced by mining wet type pneumatic dust collection device work is taken away and is entered into the deduster integrated treatment that atomizes, and the gas that does not contain dust at last is drained into the gas exhaust system by the interface of deduster end.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
