Abstract
The utility model relates to a mining suspension type orifice dust hood, which comprises an outer cover and a drill rod sleeve, wherein the outer cover and the drill rod sleeve are connected through soft connection; the dust hood is concave; the drill rod sleeve adopts front and back two-stage silica gel soft baffle plates. The utility model has the advantages that: the dust catching rate is guaranteed, the drill rod sleeve can automatically change along with the angle of the drill rod when the drill rod is applicable to inclined drilling, the outer cover can still be perpendicular to the coal wall, drilling of a drilling machine is not influenced, good sealing of the dust hood and the coal wall is kept, and the influence of vibration of the drill rod during rotation on the whole outer cover can be reduced by the soft joint.
Description
[technical field]
The utility model relates to the dust excluding hood technical field, specifically, is a kind of mining suspension type aperture dust excluding hood.
[background technology]
The harmfulness of Mine Dust is very big, not only pollutes work situation, also is detrimental to health, and more serious meeting causes burning and blast.Down-hole mining working face construction pump drainage is put boring and is carried out in coal and the processes such as gas outbursts Prediction forecast, effect verify, the test of gas basic parameter, can produce a large amount of dust, cause the whole tunnel dust to fill the air, workman's expiratory dyspnea, safety in production to mine seriously influences, and also jeopardizes miner's healthy and life security." safety regulations in coal mine " (2010) the 17th regulations " adopt the dry drilling digging laneway must take dust suppression, and use individual proofing dust and protecting articles for use ".Yet, handle the diffusion phenomena of dust in the work progress of drilling how efficiently, fast, easily, perplexing mines leaders at different levels and numerous researcher all the time, at present, also there are not effective equipment and technology to solve this problem.
At present, adopt presses air drill to advance more during the coal bed drilling construction, and particularly at driving face, coal borer perforating dust-producing amount accounts for 80～90% of the total dust-producing amount of driving.The dust that is produced not only threatens the workmen healthy under the Coal Production condition, in the Mine Dust drilling process when taking dry drilling, utilize at present the dust discharge technology of compressed air at hole bottom blowing dirt more, coal (rock) dust that dry drilling is produced is discharged along the slit between drilling rod and hole wall, and this operating type is used very general at home.But the dust concentration that this operating type produces is up to 1000mg/m
3More than, greatly polluting tunnel working space and working face, the serious harm operating personnel is healthy, and causes the dust local accumulation and burn or explode, and threatens workman's life security greatly.
Adopt measures such as aperture spraying, full section spraying, dust removing effects is relatively poor; Existing electrical dust-removing equipment is the installation and maintenance trouble under coal mine; Existing unpowered cleaner volume is unfavorable for that more greatly installation in the narrow and small tunnel, down-hole and use or dust removing effects are relatively poor.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of mining suspension type aperture dust excluding hood is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of mining suspension type aperture dust excluding hood comprises outer cover and drilling rod sleeve, it is characterized in that the drilling rod sleeve links to each other with outer cover by connecting hose; This compound mode had both guaranteed the capture rate of dust, during applicable again drilling rod inclined drilling, the drilling rod sleeve changes automatically with the drilling rod angle, outer cover is vertical rib still, neither influencing rig creeps into, keep the well airtight of dust excluding hood and rib face, the vibration when connecting hose can reduce the drilling rod rotation again is to the influence of outer cover integral body;
The matrix dust excluding hood is set catches the aperture dust and effectively save equipment occupation space, and be convenient to observe the state that creeps into of drilling rod, monitor rate of penetration at any time, the drilling rod place has or not situations such as dust leakage; With iron wire by hook with the outstanding rib that is buckled in of dust excluding hood; The tight-lipped rib of buckleing of dust excluding hood anterior device cloth bag increases the seal that covers mouth;
The drilling rod sleeve adopts the soft plate washer of front and back stages silica gel, by preceding soft plate washer the dirt slag is separated, and stops most of dust, when back plate washer prevention dust drilling rod advances from stitching thin effusion; The silica gel baffle plate also is circular to be divided into several, but good springiness, and the drilling rod that can be fit to different apertures is constructed, it is on fire to be unlikely to generate heat when rubbing with drilling rod etc., more outstanding than other product, also have when baffle plate and broken or worn and torn, can change does not influence critical piece;
The drilling rod sleeve links to each other with outer cover by connecting hose, top arrangement atomizer spray water is to the dust wet purification, two slag-drip openings are set in the bottom of this deduster device, use connecting hose draining coal dust slag, reduce the sewage draining exit wind speed, promote the secondary of dust and water to condense, and avoid the sewage draining exit gas gas too high reentrainment that causes of speed (kicking up);
The whole cylinder that adopts of dust excluding hood, inner core also adopts cylinder, and the whole inwall of the fog abundant moistening dust excluding hood of energy promotes that dust coheres the dusting aqueous mixtures at inwall; The matrix chute is established in the bottom, and dirt aqueous mixtures uni-flow vat flows to sewage draining exit, is discharged by the blowdown flexible pipe.
[description of drawings]
Fig. 1 is the structural representation of mining suspension orifice dust catcher;
Fig. 2 is the vertical view of Fig. 1;
Label in the accompanying drawing is respectively: 1, matrix dust excluding hood, 2, preceding soft plate washer, 3, the soft plate washer in back, 4, drilling rod, 5, atomizer, 6, hook, 7, wire drawing, 8, water inlet pipe, 9, ball valve, 10, slag notch, 11, connecting hose, 12, inner core, 13, the deslagging flexible pipe, 14, rig.
[specific embodiment]
See also attached Fig. 1 and 2, a kind of mining suspension type aperture dust excluding hood is provided with matrix dust excluding hood 1, described matrix dust excluding hood 1 is formed by connecting by outer wall and inner core 12, and integral body is anterior indent, and the rear portion is an annular, the outer wall top is provided with three pull hooks 6, by 3 wire drawings 7 dust excluding hood is hung on rib.When the drilling rod 4 of rig 14 advances, during from boring spirt dust excluding hood, the drilling rod jacket casing that preceding soft plate washer 2, the soft plate washer 3 in back and inner core 12 are formed prevents that dust from leaking along drilling rod to dust on drilling rod with compressed air, and jacket casing adopts connecting hose 11 outer cover indent to link to each other.4 atomizers of inwall top arrangement 5 ejection fogs with dust excluding hood in dust condense, atomizer is connected to water inlet pipe 8 with 90 degree elbows and threeway respectively, controls inflows at the anterior dress of water inlet pipe ball valve 9.The dust water of cohesion imports two circular hole slag notches 10 in the dust excluding hood bottom by the funnel type chute, and slag flexible pipe 13 controls of running in are respectively discharged.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection domain of the present utility model.
