Description

Novel dust-proof curtain for return airway

Technical Field

The utility model relates to a novel return airway dustproof curtain is particularly useful for adopting the coal mining method of caving coal and the great mine of working flour dirt.

Background

A dust curtain for a return airway is a device which is widely applied to the fields of mining and geotechnical engineering and used for controlling dust in the return airway. At present, the dust-proof curtain of the return airway mainly comprises a fixed rod, a sprayer and a dust-proof curtain. Wherein, atomizer and dustproof curtain pass through the dead lever to be fixed in the tunnel, make dustproof curtain cover the whole cross-section in tunnel almost, and the atomizer is fixed in the dead lever below. When the working face is produced, the sprayer is opened to spray downwards, so that the dust falling effect is achieved. But because the dustproof curtain goes up sewage more, the area is great, makes the pedestrian pass through comparatively trouble, and the sewage that flows down from the dustproof curtain makes the tunnel very dirty and disorderly moreover. When the pedestrian passes through the dustproof curtain, the pedestrian needs to lift the dustproof curtain by hand to pass through the narrow space.

Therefore, in coal mine production, how to effectively treat sewage flowing down on the curtain cloth and pedestrians conveniently pass through the dust-proof curtain cloth so as to realize efficient and green mines is a key problem to be solved by technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem that exists among the above-mentioned prior art, the utility model provides a novel dust curtain in return airway, this dust curtain not only can control the sewage that flows down on the dust curtain effectively, makes the tunnel make the pedestrian cleaner and tidier, can let the convenient dust curtain that passes through of workman moreover.

The above purpose is realized by the following technical scheme:

the utility model provides a novel return airway dust curtain which constitutes and includes: fixing device, atomizer, dustproof curtain, sewage treatment plant.

The fixing device comprises a sprayer fixing rod and a dustproof curtain fixing rod. The atomizer dead lever is two cylindrical metal poles, and the symmetric distribution is in the curtain both sides. The dustproof curtain fixing rod is also a cylindrical metal rod and is positioned between the two sprayer fixing rods. The three rods are welded together in sequence.

The sprayer is a common mine dust fall sprayer and is fixed below the sprayer fixing rod.

The dustproof curtain is an ordinary mining dustproof curtain, the curtain is fixed through a metal ring with the diameter larger than the diameter of a dustproof curtain fixing rod, and two sides of the dustproof curtain can be pulled inwards.

The sewage treatment device comprises a fixed hook, a sewage tank and a water pipe. The fixed hook is a metal hook, and a hook base is fixed with the sewage tank and hung below the dustproof curtain cloth; the sewage tank is a semicircular hard glass water tank; the water pipe is a mining soft water pipe, the diameter of the water pipe is larger than that of the sewage tank, and the water pipe can be tightly sleeved on the sewage tank.

The utility model has the advantages that: the utility model discloses in, three metal poles among the fixing device are fixed at two sides in the tunnel to evenly fix four atomizers down respectively under two atomizer dead levers, will prevent dust the curtain and fix in dustproof curtain dead lever below through the metal circle that the diameter is greater than dustproof curtain dead lever, hang sewage treatment plant in dustproof curtain below at last: during the working face production, can produce a large amount of dust, open the atomizer switch, the dust is at the big lane in-process that flows through the return air tunnel, combines with water when dustproof curtain to form sewage, flows down along the curtain, flows to sewage treatment plant's bilge pit to flow to the basin both sides to the water pipe, water pipe end connection water drainage tank makes sewage finally discharge through water drainage tank, makes the tunnel more clean and tidy. And when the pedestrian passes through, because the curtain passes through the becket to be hung in dustproof curtain dead lever below, the pedestrian can pass through after pulling the curtain open like drawing the window curtain, treats to pull back dustproof curtain after passing through, and the operation is convenient, and the space of passing through is big, can let many people pass through fast moreover.

The advantages are that: the utility model relates to a rationally, simple structure, convenient to use can make the environment that makes the tunnel when reaching dustproof purpose comparatively clean and tidy, has solved the pedestrian simultaneously and has passed through inconvenient problem.

Fig. 1 is a schematic diagram of the present invention.

FIG. 2 shows a view of the fixing device.

FIG. 3 is a schematic diagram of a sewage treatment apparatus.

In the figure, 1, a sprayer fixing rod, 2, a dustproof curtain fixing rod, 3, a dustproof curtain, 4, a fixing hook, 5, a sewage tank, 6, a water pipe and 7, a sprayer are arranged.

Detailed Description

As shown in the figure, the novel dustproof curtain of the return airway comprises: fixing device, atomizer 7, dustproof curtain 2, sewage treatment plant. The fixing device comprises a sprayer fixing rod 1 and a dustproof curtain fixing rod 2. The atomizer dead lever 1 is two cylindrical metal poles, and the symmetric distribution is in dustproof curtain 3 both sides. The dustproof curtain fixing rod 2 is also a cylindrical metal rod and is positioned between the two sprayer fixing rods 1. The three rods are welded together in sequence. The sprayer 7 is a common mine dust fall sprayer and is fixed below the sprayer fixing rod 1. Dustproof curtain 3 is ordinary mining dustproof curtain, and the curtain is fixed through the metal ring that the diameter is greater than dustproof curtain dead lever diameter, and both sides can inwards be spur. The sewage treatment device comprises a fixed hook 4, a sewage tank 5 and a water pipe 6. The fixed hook 4 is a metal hook, and a hook base is fixed with the sewage tank 5 and hung below the dustproof curtain 3; the sewage tank 5 is a semicircular hard glass water tank; the water pipe 6 is a mining soft water pipe, the diameter of the water pipe is larger than that of the sewage tank 4, and the water pipe can be tightly sleeved on the sewage tank.

Three metal poles in the fixing device are fixed at two sides in the tunnel to 1 evenly fixes four atomizer 7 down respectively under two atomizer dead levers, fixes dustproof curtain 3 in dustproof curtain dead lever 2 below through the metal circle that the diameter is greater than dustproof curtain dead lever 2, hangs sewage treatment plant in dustproof curtain 3 below through fixed couple 4 at last: when the working face is produced, a large amount of dust is generated, the sprayer 7 is turned on at the moment, the dust is combined with water to form sewage when passing through the dustproof curtain 3 in the process of flowing to the main roadway through the return airway, the sewage flows down along the curtain and flows into the sewage tank 5 of the sewage treatment device, the sewage flows to the water pipe 6 from two sides of the water tank, and the tail end of the water pipe is connected with the drainage tank, so that the sewage is finally drained away through the drainage tank, and the roadway is cleaner and tidier. And when the pedestrian passes through, because dustproof curtain 3 hangs in dustproof curtain dead lever 2 below through the becket, the pedestrian can pass through after pulling the curtain open like drawing the window curtain, treats to pull back dustproof curtain 2 after passing through, and the operation is convenient, and the space of passing through is big, can let many people pass through fast moreover.
