Abstract
The utility model discloses a coal slime clearing device for a coal mine underground small water-absorbing well, which comprises a water sump, wherein a sewage pump is arranged on the inner wall of the bottom of the water sump, a high-pressure rubber pipe is connected to an output port of the sewage pump, a galvanized pipe is arranged in the water sump, and a ball valve is arranged at one end of the galvanized pipe. The utility model solves the problem that the small water-absorbing well of the main drainage pump room is difficult to clean, ensures the normal operation of the water pump, ensures the safety of workers and simultaneously improves the working efficiency.
Description
Technical Field
The utility model relates to the technical field of coal mines, in particular to a coal slime cleaning device for a small water-absorbing well under a coal mine.
Background
The central water pump room of the coal mine aims to solve the problem of water burst discharge of the whole mine so as to ensure the drainage safety of the whole mine. The central water pump room can be ensured to normally drain water, the integrity of drainage equipment is particularly important in coal mine safety production, the mine production has large mine water yield, a large amount of coal slime enters a small water-absorbing well along with sewage to cause difficulty in drainage, and a pump body enters the coal slime to have high failure rate.
When the coal slime deposited in the small water-absorbing well is cleaned, the water in the small water-absorbing well is drained firstly, and workers enter the small water-absorbing well to perform manual operation after checking toxic and harmful gases, so that the method is time-consuming, labor-consuming and unsafe. Because the mine gushes out the water yield greatly, the work of drawing clearly can't be accomplished to the manual work, this device of special transformation installation. After the device is used, workers do not need to enter a small water-absorbing well, and the coal slime is directly discharged to a water ditch of a bottom-hole yard by using a sewage pump; the safety is ensured, the cleaning efficiency is improved, and the time and the labor are saved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a coal slurry cleaning device for a coal mine underground water-absorbing small well.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a clear device of drawing of colliery sump pit coal slime, includes the sump, sump bottom inner wall is provided with the dredge pump, and the delivery outlet of dredge pump is connected with the high-pressure rubber pipe, the inside galvanized pipe that is provided with of sump, and galvanized pipe one end is provided with the ball valve, the specification of ball valve is phi 19.
The utility model has the beneficial effects that:
1. the small water-absorbing well is only needed to be drawn clearly after the clear drawing device is used, and the safety is guaranteed and the efficiency is improved because no personnel are needed to enter the small water-absorbing well. This achievement has solved the problem that main drainage pump house water absorption small well is difficult to clear and elutriates, has guaranteed the normal operating of water pump, and has improved work efficiency when having guaranteed worker's safety.
Drawings
FIG. 1 is a schematic structural diagram of a coal slurry clearing device for a coal mine underground water absorption small well, which is provided by the utility model.
In the figure: 1. a water sump; 2. a sewage pump; 3. a high-pressure rubber hose; 4. galvanizing the pipe; 5. a ball valve.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1, the coal slime clearing device for the coal mine underground water-absorbing small well comprises a water sump 1, wherein a sewage pump 2 is arranged on the inner wall of the bottom of the water sump 1, a high-pressure rubber pipe 3 is connected to an output port of the sewage pump 2, a galvanized pipe 4 is arranged inside the water sump 1, a ball valve 5 is arranged at one end of the galvanized pipe 4, and the ball valve 5 is phi 19 in specification.
The working principle is as follows: the coal slime around a bottom valve of the water pump is flushed by high-pressure water supplied underground, then the coal slime is discharged into a ditch of a bottom shaft vehicle yard by a dredge pump 2, and the sediment is manually removed from the ditch of the bottom shaft vehicle yard; when the galvanized steel pipe deep into the small water absorption well is connected with the high-pressure water pipe, a special U-shaped clamp is required and the connection is firm; the sludge discharge pipe of the sludge pump 5 must be firmly connected.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
