Description
(1) technical field
The utility model relates to a kind of water conservancy equipment facility, particularly a kind of sediment transport through pipeline surge tower.
(2) background technique
Exploitation of coal resources industry is while promotion various places economic development, and also to bringing many negative effects, cause comparatively serious geological ecology and destroy, part Rive flood routing, road, bridges and culverts break convergence, hydroelectric facility damages.Long-term ponding region, mining collapse area, Cultivated Land Area Decrease, grain drop in production, total crop failure, agricultural economy loss is huge.Pressure coal village house spot splits, tilts, collapses, masses' security of the lives and property in serious threat subsidence area, also has a strong impact on layout and the process of this area's urbanization simultaneously.Utilize sediment transport through pipeline technology, Yellow River mud can be transported to subsided land from coal mine and carry out filling, at the former mold of filling silt Surface mulch, reach natural ground level or close to natural ground level, recover original cultivated land function.
But in the process of sediment transport through pipeline, when secondary pumping plant breaks down, the quantity of sand and mud carried in pipeline will exceed the transportability of sediments of secondary pumping plant, causes the damage of equipment.When secondary pumping plant normally works, and chopped-off head pumping plant breaks down, and when not reaching design feed flow, the quantity delivered of secondary pumping plant is not enough; cause equipment to dally, damage equipment, waste energy; and once break down, will shutdown maintenance, this all can cause very large loss to whole sediment transport system.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides the continuous non-stirred of a kind of remote pipe multistage booster station pipeline and automatically regulates and have the sediment transport through pipeline surge tower of the features such as Cemented filling silt high efficiency, low energy consumption, low cost, environmental protection.
The utility model is achieved by the following technical solution:
A kind of sediment transport through pipeline surge tower, comprise sediment delivery pipe, it is characterized in that: also comprise PLC control system, described sediment delivery pipe is upwards connected with setting pipeline, wet pit is provided with above described sediment delivery pipe, the upper outlet of described setting pipeline is curved downwards and towards wet pit, reverse time only valve is connected with between described wet pit and setting pipeline, described wet pit is provided with drain valve, described wet pit is supporting to be had for the motor-pumped well of wet pit moisturizing and submersible pump, pressure transducer is provided with in described wet pit, described pressure transducer, stop valve reverse time, drain valve and pressure transducer are connected with PLC control system circuit respectively.
The height of described setting pipeline is 40 meters, and its internal diameter is 0.1 meter, and the distance between described wet pit and sediment delivery pipe is 15 meters.
Described setting pipeline is made up of superhigh molecular weight polyethylene material.
Described setting pipeline peripheral hardware has duct frame.
The beneficial effects of the utility model are:
When chopped-off head pumping plant normally work, secondary pumping plant break down or quit work time, the slurry carried by sediment delivery pipe will be moved upward by erectting pipeline, through downward outlet earial drainage in wet pit, when the water level in wet pit exceedes Liquid level display, drain valve is opened, and is automatically drained into hold by the water in wet pit and lets out region;
When secondary pumping plant normally works, and chopped-off head pumping plant is when breaking down, slurry quantity not sufficient in sediment delivery pipe, when not reaching the slurry amount of design conveying, pressure in sediment delivery pipe reduces, erect the husky water yield of supplementing and lacking that will lower of water in pipeline, now erect ducted pressure will correspondingly diminish, stop valve reverse time automatically to open under the effect of pressure reduction, the water in wet pit flows out, and adds in sediment delivery pipe, simultaneously, submersible pump works, and maintains the liquid level in wet pit, ensures that secondary pumping plant is carried according to design discharge.Being adjusted to fix a breakdown in time and gaining time by above-mentioned two situations, raises the efficiency, maintains the normal operation of whole pipeline slurry pipeline steel system.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure, 1 sediment delivery pipe, 2 erect pipeline, 3 duct frame, 4 wet pits, stop valve, 6 drain valves, 7 pressure transducers, 8 submersible pumps, 9 PLC control system, 10 motor-pumped wells 5 reverse times.
(5) embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, this kind of sediment transport through pipeline surge tower, sediment delivery pipe 1 and PLC control system 9, sediment delivery pipe 1 is upwards connected with and erects pipeline 2, erect pipeline 2 to be made up of superhigh molecular weight polyethylene material, it is supported by duct frame 3, duct frame 3 preferably steel structure, erect pipeline 2 upper end to be bent downwardly, it is 40 meters from sediment delivery pipe 1 and the distance h of the joint to the peak erectting pipeline 2 of erectting pipeline 2, the internal diameter erectting pipeline 2 is 0.6 meter, above sediment delivery pipe 1, d=15 rice is provided with wet pit 4, the volume keeping water in wet pit 4 is 100 cubic metres, Liquid level height 5 meters, the outlet towards erectting pipeline 2 suitable for reading of wet pit 4, reverse time only valve 5 is connected with between wet pit 4 and setting pipeline 2, wet pit 4 is provided with drain valve 6, wet pit 4 is supporting to be had for the motor-pumped well 10 of wet pit 4 moisturizing and submersible pump 8, submersible pump 8 is positioned at motor-pumped well 10, pressure transducer 7 is provided with in wet pit 4, pressure transducer 7, stop valve 5 reverse time, drain valve 6 and pressure transducer 7 are connected with PLC control system 9 circuit respectively.
When chopped-off head pumping plant normally work, secondary pumping plant break down time, the water sand carried by sediment delivery pipe 1 will be moved upward by erectting pipeline 2, along with increasing in water sand, pressure increase in sediment delivery pipe 1, the water sand exceeding secondary pumping plant transportability of sediments is discharged in wet pit 4 by erectting pipeline 2, alleviates the pressure in sediment delivery pipe 1; When the water level in wet pit 4 exceedes Liquid level display, drain valve 6 is opened, and the water in night cylinder is drained into automatically planning region; When secondary pumping plant normally works, and chopped-off head pumping plant is when breaking down, defeated slurry quantity not sufficient in sediment delivery pipe 1, when not reaching design slurry body amount, pressure in sediment delivery pipe 1 reduces, erect the husky slurry amount of supplementing and lacking that will lower of water in pipeline 2, now the pressure erect in pipeline 2 will correspondingly diminish, stop valve 5 reverse time automatically to open under the effect of pressure reduction, the water in wet pit 4 flows out, and adds in sediment delivery pipe 1, simultaneously, submersible pump 8 works, and maintains the liquid level in wet pit 4, ensures that secondary pumping plant is carried according to design discharge.
Except technical characteristics described in specification, all the other technical characteristicss are those skilled in the art's known technology.
