Abstract

The utility model discloses an utilize sump waste fitting discharging in pit of high-pressure wind belongs to the blowdown system field in the pit, and what mainly solve is that the silt that sump deposits in the pit blocks up the sewage pump suction opening, causes the problem that the dredge pump head damaged and motor burns out even. Utilize the sump waste fitting discharging in pit of high-pressure wind to include the blow off pipe, the dredge pump, the sump still includes a plurality of tuber pipes, with tuber pipe disect insertion sump bottom, utilize valve control to send the high-pressure wind of earth's surface air compressor station into the sump bottom via the tuber pipe, stir the silt and the clear water that the sump bottom precipitated, recycle the dredge pump and discharge, the back of having discharged, adopt the high-pressure wind again to blow the muddy water in the blow off pipe to next-level sump, concrete sedimentation in the muddy water has been avoided solidifying, block up the problem of blowdown pipe. The utility model discloses simple structure, it is easy and simple to handle, durable, extensive applicability.

Description

Underground water sump pollution discharge device utilizing high-pressure air

Technical Field

The utility model belongs to the sewage system field in the pit, concretely relates to utilize sump waste fitting discharging in pit of high-pressure wind.

Background

The method is characterized in that impact type rock drilling is usually adopted during rock drilling of each working face of each plane in the well, water is required to be injected continuously during rock drilling, waste water is generated, in addition, more tunnels have water seepage or water burst, and therefore a large number of water bins are arranged in the well.

Sewage need be arranged to the sump from each tunnel, and the drainage is gradually concentrated in grades, therefore often can deposit more silt in the sump, can block up the sewage pump suction opening when the accumulation is more, causes the damage of sewage pump head and motor to burn out even, and artifical clearance silt has the clearance untimely, the clearance degree of difficulty is big, cleaning efficiency hangs down, silt transports difficulty scheduling problem.

After sewage had been taken out, there was full pipe muddy water in the blow-off pipe always, and wherein contain a small amount of concrete liquid, can persist in the blow-off pipe always, until opening the dredge pump next time, could discharge muddy water, muddy water persists for a long time like this, and the concrete can deposit and solidify, can block up the sewage pipes gradually for a long time repeatedly, and is difficult to the investigation mediation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an utilize sump waste fitting discharging in pit of high-pressure wind to solve the silt that deposits in the sump in pit and block up the sewage pump suction opening, cause the problem that the sewage pump head damaged and the motor burns out even.

In order to solve the above problems, the utility model discloses the technical scheme who takes is:

the utility model provides an utilize sump waste fitting discharging in pit of high-pressure air, includes the sump, and blow off pipe outlet section, still includes first tuber pipe, the export of first tuber pipe divides two the tunnel, communicates with the second tuber pipe is perpendicular all the way, and the other end of second tuber pipe inserts the sump bottom downwards, is equipped with first valve on the second tuber pipe, another sweetgum fruit of first tuber pipe is equipped with the third valve through the coaxial intercommunication of third tuber pipe and blow off pipe outlet section on the third tuber pipe.

The utility model has the advantages as follows:

high-pressure air is sent into the sump before drawing water, stirs clear water and silt in the sump, later draws water and discharges, blocks up the sewage pump suction opening when having avoided the silt accumulation of sediment more, causes the wearing and tearing of sewage pump head to damage and the motor burns out even, and then has avoided the shut down of this class of problem of construction engineering.

After pumping water, high-pressure air is used for blowing away muddy water in the sewage discharge pipe, so that the problem that concrete in the muddy water is precipitated and solidified to block the sewage discharge pipe is solved. The utility model discloses simple structure, durable, extensive applicability.

Drawings

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

the reference numbers are as follows: 1-a water sump; 2-a first air duct; 3-a second air duct; 4-a first valve; 5-a third air duct; 6-a third valve; 7-a drain outlet section; 8-the middle section of the sewage draining pipe; 9-a second valve; 10-a sewage pump; 11-inlet section of sewage draining pipe

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, a downhole sump blowdown apparatus using high pressure air, firstly, a bracket is made of an anchor rod on the wall of a downhole tunnel, a hook is arranged on the bracket, a first air pipe 2 is clamped in the hook, the other end of the first air pipe 2 is connected with a second air pipe 3, a third air pipe 5 is connected through a three-way joint, the second air pipe 3 is inserted into the bottom of the sump 1, the first air pipe 2 and the third air pipe 5 are communicated in a straight line, the second air pipe 3 is connected with a first valve 4 through a flange, the third air pipe 5 is connected with a third valve 6 through a flange, the other end of the third air pipe 5 is connected with a blowdown pipe outlet section 7, a blowdown pipe middle section 8 is connected through a reducing three-way, the third air pipe 5 is communicated with the blowdown pipe outlet section 7 in a straight line, the second valve 9 is connected to the blowdown pipe middle section 8 through a flange, a blowdown pump 10 is connected to the bottom end of the blowdown pipe middle section 8 through, the sewage pump 10 is directly arranged on a platform beside the water sump 1, the sewage pump 10 is provided with a pipe, the pipe is a sewage pipe inlet section 11, the sewage pipe inlet section 11 directly extends into the bottom of the water sump 1, the other end of the sewage pipe outlet section 7 extends to the water sump of the next level, and the pipe orifice is downward and fixed in the water sump of the next level.

Further, first tuber pipe 2, second tuber pipe 3, third tuber pipe 5 all adopt DN 25's welded tube, and blow off pipe export section 7, blow off pipe interlude 8, blow off pipe entry section 11 all adopt welded tube or polyvinyl chloride plastic tubing more than DN50, and the welded tube of different bores passes through the reducing and connects.

Before the pollution discharge operation, the first valve 4 is opened, high-pressure air is sent into the water sump 1, and clear water and sludge precipitated at the bottom of the water sump 1 are stirred; and then opening the second valve 9, starting the sewage pump 10 to pump water, turning down the first valve 4 along with the reduction of the water level, finishing the drainage, closing the first valve 4 and the second valve 9, opening the third valve 6, blowing the system air of the ground surface air compressor station to the sewage outlet section 7 through the first air pipe 2 and the third air pipe 5, blowing muddy water in the sewage outlet section 7 to the next-stage water sump, and closing the third valve 6 after the muddy water is completely blown.
