Abstract
The utility model is related to a kind of drainage system under coal mine, specially a kind of backpulsing underground main drainage system.The problems such as blocking that solution underground drainage system is present is serious, including sump, drinking-water pipe, drinking-water pipe connection water pump and motor, pump outlet connection drainpipe are provided with sump, drainpipe connects two and removes ground delivery pipe respectively, go ground delivery pipe to be provided with valve, connect recoil drainage tube on a ground delivery pipe wherein, recoil drainage tube is provided with recoil valve, recoil drainage tube connects recoil tube by three-way valve, in described recoil tube insertion sump.Under normal operation, water in sump is sent to ground delivery pipe by water pump, once there is clogging, can be by valve closing, recoil valve is opened simultaneously, and recoil drainage tube and recoil tube constitute an interior circulation, by the effect of water pump, water is set to recoil in the effect in sump, reaching cleaning blocking.Solve the accumulation of water suction The Small Well coal slime, the hidden danger of blocking pipeline.
Description
Technical field
The utility model is related to a kind of drainage system under coal mine, specially a kind of backpulsing underground main drainage system.
Background technology
, it is necessary to use substantial amounts of water in coal mining, and the substantial amounts of underground water that can also gush out in recovery process.Cause
This in time discharges the water of underground, is one of important leverage measure of safety in production.Underground drainage system design comparison is simple, leads to
Cross and set up sump collection water, and extracted out the water in sump using water pump.But there are the following problems for this system：
1. coal slime is more in underground coal mine main drainage system, although periodic cleaning is big but go back often aggregation in the The Small Well that absorbs water
Amount coal slime, blocks suction hose tap, drain discharge decline, main drain pump and motor is chronically at poorly efficient consumption state high, equipment
Performance consume is serious, and service life shortens；
2. need continuous recoil multiple because coal slime is more, when main draining driver draws water, break up what is blocked in water suction The Small Well
Coal slime ability proper drainage, the operation used time is more more than proper drainage operational sequence, such as the situation that water yield is larger, can cause storehouse
Full, swelling Chu great lanes and gas accident；
3. the coupling cock of sump and water suction The Small Well is often extruded by coal slime and blocked, and prevents sump water burst small from smoothly flowing to
Well, increased draining difficult.
The content of the invention
A kind of the problems such as blocking of the utility model in order to solve underground drainage system presence is serious, there is provided backpulsing well
Lower main drainage system.
The technical solution of the utility model is, a kind of backpulsing underground main drainage system, including sump, is provided with sump
Drinking-water pipe, drinking-water pipe connection water pump and motor, pump outlet connection drainpipe, drainpipe connects two and goes to ground to discharge respectively
Pipe, goes ground delivery pipe to be provided with valve, connects recoil drainage tube on a ground delivery pipe wherein, is set on recoil drainage tube
There is recoil valve, recoil drainage tube connects recoil tube by three-way valve, in described recoil tube insertion sump.
Under normal operation, the water in sump is sent to ground delivery pipe by water pump, once there is clogging,
Can be by valve closing, while opening recoil valve, recoil drainage tube and recoil tube constitute an interior circulation, by water pump
Effect, makes water recoil in the effect in sump, reaching cleaning blocking.Solve the accumulation of water suction The Small Well coal slime, blocking pipeline it is hidden
Suffer from.
The utility model design is ingenious rationally, is that the recoil for being capable of achieving coal slime is cleaned by increasing a pipeline, solves
Suction hose tap is blocked, drain discharge decline, main drain pump and motor is chronically at poorly efficient consumption state high, equipment performance consume
Seriously, the problem that service life shortens；And increased displacement, it is ensured that production security.

Specific embodiment
As schematically shown in Figure 1, a kind of backpulsing underground main drainage system, including sump 14, drinking-water pipe is provided with sump 14,
Drinking-water pipe connects water pump 8 and motor 9, and the delivery port of water pump 8 connection drainpipe 7, drainpipe 7 connects two and removes ground delivery pipe respectively
1st, 4, go ground delivery pipe 1,4 to be provided with valve 2,3, recoil drainage tube 6, recoil are connected on a ground delivery pipe 4 wherein
Drainage tube 6 is provided with recoil valve 5, and recoil drainage tube 6 connects recoil tube 16 by three-way valve 15, and described recoil tube 16 is inserted
In entering sump 14.
14 points described of sump is several water suction The Small Wells, and described water pump 8 and motor 9 has three sets, and described recoil is drawn
Three recoil tubes 16 are connected in flow tube 6, each recoil tube 16 is respectively placed in a water suction The Small Well.
