Abstract
A washing method of a full and gravity pipeline is provided in the invention, which is that: the upper end of a water supply pipe(3) is connected with a head tank (1); the lower end is connected with a filling-up pipe(6) through a brake vale (4); the filling pipe goes to a goaf filling (9) of mining downhole; equal pipe diameter of the water supply pipe and the filling pipe, and the height of outlet of the head tank is higher than that of the filling pipe; the outlet of the head tank and the outlet of the filling pipe are respectively provided with brake valves (2, 8); an outlet pipe (10) and the filling pipe are connected with each other in front of the outlet brake valve; the outlet pipe is provided with a brake valve(7), and the filling pipe is connected with a conveying pump (5); after the convey pump stops conveying slurry, the outlet brake valve of the filling pipe is closed; the brake valve on the outlet pipe and that between the brake valve outlet of the head tank and the filling pipe are opened, so as to wash the filling pipe until clean water flows out from the outlet pipe. The invention has simple technical flow with good technical continuity and high washing efficiency, and the residue of slurry can be completely removed.
Description
Technical field
The invention belongs to filling in mine mining technique field.
Background technology
Adopt the mine of the method for mining by the way of filling, generally adopt last mortar, the glued last mortar of high concentration, lotion slip or crushed stone concrete filling hole goaf down, change the goaf stress state, to satisfy the requirement of safety mining.Tailings, lotion slip and crushed stone concrete all adopt pipeline to be transported to goaf down, hole.Last mortar, the glued last mortar of high concentration adopt the gravity flow mode of movement, after mortar is carried and is finished, open wash tub pipe, conveyance conduit is washed, and the intermittent flushing pipe of flushing water in the pipeline is after the flushing, crook under the local pipeline, stay a little residue,, may cause line clogging if downward bent part part pipeline is longer.Lotion slip or crushed stone concrete adopt the pump mode of movement, and slip is opened wash tub pipe after carrying and finishing, with the pump transporting water pipeline is washed, the intermittent flushing pipe of flushing water in the pipeline is after the flushing, duct bottom stays a little residue, because slurry contains cement or other Binder Materials, the time has been grown, duct bottom meeting condensation cure one layer concrete or solidfied material, conduit section is dwindled, increase the pipeline transporting resistance, pipeline is removed out piecemeal for this reason, clear up.Sometimes also adopt high-pressure blast to mix pipeline purging, but effect is also with preceding identical with water.And washing time is longer, needs about 60 minutes, and flushing pipe efficient is low.
Summary of the invention
Purpose of the present invention provides in order to solve the deficiency that above-mentioned prior art exists just that a kind of technological process is simple, the technology continuity is good, pipeline cleaning efficiency height, slurry residue are removed clean full pipe gravity flow pipeline flushing method.
The objective of the invention is to be achieved through the following technical solutions.
Full pipe gravity flow pipeline flushing method, method is as follows:
1. the water supply line upper end is connected with head-tank, the lower end is connected with filling pipeline by gate valve, and filling pipeline leads to the underground goaf of mining; Water supply line is identical with the caliber of filling pipeline, head-tank go out the outlet that open height is higher than filling pipeline, be respectively arranged with gate valve in the outlet of head-tank and the outlet of filling pipeline, before being positioned at the outlet gate valve, filling pipeline is connected with outlet pipe, outlet pipe is provided with gate valve, and filling pipeline is connected with delivery pump;
2. after delivery pump stops to carry slurry, filling pipeline is exported gate valve (8) closes, gate valve on the outlet pipe (7) places full open position, open the gate valve (4) between head-tank outlet gate valve (2) and water supply line and the filling pipeline, beginning flushing filling pipeline flows out clear water until the outlet pipe outlet;
The water velocity of the inventive method flushing filling pipeline is greater than slurry material critical flow velocity.The time of flushing filling pipeline is 10～15 minutes.
Adopt method of the present invention, when lotion slip in the filling pipeline carry substantially finish after, open the water supply line gate valve, all open until gate valve, the water of water supply line is all filled with filling pipeline, form full packages from stream mode, under the effect of natural pressure reduction, the filling in-pipe flow reaches the flow at high speed state, surpassed the slurry critical flow velocity, at this moment the residue in the pipeline along with current flow out filling pipeline, thereby reaches the purpose that pipe flushing is clean.Technological process of the present invention is simple, the flush efficiency height, and less energy consumption does not stay residue in the pipeline.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, method of the present invention is, water supply line 3 upper ends are connected with head-tank 1, and the lower end is connected with filling pipeline 6 by gate valve 4, and filling pipeline 6 leads to underground goaf 9; Water supply line 3 is identical with the caliber of filling pipeline 6, head-tank 1 go out the outlet that open height is higher than filling pipeline 6, in the outlet of head-tank and the outlet of filling pipeline gate valve 2 and gate valve 8 are set respectively.Connect outlet pipe 10 before filling pipeline is positioned at outlet gate valve 8, outlet pipe is provided with gate valve 7, and filling pipeline connects delivery pump 5.During work, when delivery pump 5 stops after slurry is carried in goaf 9, gate valve between water supply line and the filling pipeline 4 is placed full open position, closing gate valve 8, gate valve 7 places full open position, opens head-tank 1 outlet gate valve 2 gradually, beginning flushing filling pipeline, the water slurry of flushing flows out from outlet pipe 10, does not enter goaf 9.Washing time was generally 10～15 minutes, flowed out clear water until outlet pipe 10 outlets.The water velocity V of flushing filling pipeline must be greater than slurry material critical flow velocity V
0, choose coefficient of reliability m=V ÷ V usually
0〉=1.3.
Slurry material critical flow velocity V
0Computing formula as follows:
In the formula, d is maximum material particular diameter, and unit is mm.
General maximum material particular diameter is 10mm, calculates V
0So=4.29m/s is general V 〉=5.58m/s.
