Abstract

The utility model discloses a mud salvage tube which comprises a steel cylinder with two ends open. A circular base seat is fixed on the edge of the bottom end of the steel cylinder, and a movable hinge is arranged at the upper end of the circular base seat through a fixed shaft connected on the base seat. When the mud salvage tube is used for cleaning mud, the hinge is pressed and opens upwards, and the mud enters the steel cylinder. When the steel cylinder is filled with the mud, the mud salvage tube is lifted, the hinge closes, and the mud salvage tube is lifted to ground. The mud salvage tube further comprises a salvage tube liquid-releasing platform in matching using with the salvage tube, the salvage tube liquid-releasing platform comprises a base plate and two stand columns fixed on the base plate perpendicularly, and the two stand columns can push the hinge open to release the mud liquid. The mud salvage tube is manufactured according to the theory of a check valve, and an original pipeline underground mud discharging process is changed into ground pumping and discharging, a mud discharging risk is reduced, the mud liquid can be discharged to the utmost degree, and accidents can be prevented from occurring. The mud salvage tube improves work efficiency, and is simple and easy to operate, and pumping and discharging is thorough, and manufacturing materials are easy to select.

Description

Mud is salvaged pipe

Technical field

The utility model relates to a kind of plasma discharge Accrete clearing device that extracts the device, particularly a kind of mine gas pipeline of solidliquid mixture in pipeline.

Background technology

The gas that the down-hole extraction is discharged needs to be delivered to ground by the gas tube well, needs at the bottom of the gas tube lower going-into-well after the construction of gas tube well shaft is finished, and by returning paste-making method the piping shaft pipeline is fixed.

After solid plumber's journey finished, slurries and water remained in the pipeline, and the water that floats over the upper strata can pass through the deep well pump pump drainage, but the concentration of slurry of lower floor is large, can't extract out with pump.In the past plasma discharge process using underground construction is visited lane or boring, punches the seamless steel pipe of gas tube slurries are discharged.This method row silt has a big risk, efficient is low, and slurries can't be discharged fully.In the past some mines once because of pipeline in mud do not clean out the accident of occuring.This kind operation is desilting in large in the degree of depth, that diameter the is little pipeline, and the method for present domestic employing all is from the bottom white-out, and this method efficient is low, row is unclean, leaves over easily hidden danger, and is accidents caused.

Summary of the invention

The purpose of this utility model be solve gas tube well array that in the past plasma discharge technique causes become silted up have a big risk, efficient is low, can't discharge the problem of slurries fully, provides a kind of mud to salvage pipe.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of mud is salvaged pipe, comprises the steel cylinder of a both ends open, steel cylinder bottom edge stationary annular base, and movable hinge is installed by the fixed axis that is connected on the base in the annular base upper end.

During use, salvage pipe with the boring tower fixation, put into gas tube downwards, when salvaging pipe contact mud, the hinge pressurized upwards opens, and mud enters steel cylinder, after mud is filled steel cylinder, upwards promote and salvage pipe, hinge is closed, and will salvage pipe and upwards be promoted to ground.

The utility model also comprises one and the matching used salvaging pipe tapping platform of salvaging pipe, salvages pipe tapping platform and comprises substrate and two columns that are vertically fixed on the substrate.On carry salvaging pipe to the ground and be placed on and salvage on the pipe tapping platform, two columns can back down hinge, emit slurries.

The utility model is the slurries fishing tool of making according to the non retern valve principle, changes plasma discharge technique under the piping shaft in the past into the ground pump drainage, and (1) is safe, has reduced the plasma discharge risk, can at utmost discharge slurries, the generation of Accident prevention; (2) promoted operating efficiency, pump drainage is clean, and is simple, easy to operate, makes material and chooses easily.

The specific embodiment

Below in conjunction with accompanying drawing the claimed technical scheme of the utility model is done and to be specified.

A kind of mud described in the utility model is salvaged pipe, comprises the steel cylinder 1 of a both ends open, steel cylinder 1 bottom edge stationary annular base 2, and movable hinge 4 is installed by the fixed axis 3 that is connected on the base 2 in annular base 2 upper ends.Simultaneously, comprise that is also salvaged a pipe tapping platform, salvage pipe tapping platform and comprise substrate 5 and two columns 6 that are vertically fixed on the substrate.

Be described further as an example of Shanxi coal group Cheng Zhuan ore deposit gas tube well array slurry example.

Cheng Zhuan ore deposit No. 2 ventilating shaft 3# gas tube well, construction well vertical depth 210m, the gas pipeline depth of setting is 198m, pipe well φ 750mm, estimate that in No. 3 coal seams disclosing the position is 194m, gas tube well actual measurement depth of mud is 170m, and predictable pressure is 1.7MPa, and the anti-aperture (146*160mm) of starching, bottom enters seat earth 3m.

1. fishing tool is made

1.1 fishing tool is chosen the seamless steel pipe less than gas tube well diameter and is made steel cylinder 1, length can be decided according to the boring tower height (generally choose boring tower height 1/2nd), pipe thickness is chosen 8-15mm and all can, also strengthening because be accompanied by the increase deadweight of the degree of depth, can insert in the mud salvaging pipe fully.Cheng Zhuan ore deposit No. 3 gas tube wells of No. 2 ventilating shafts are chosen and salvaged the seamless steel pipe diameter is 0.5m, and length is 8m, and pipe thickness is chosen 15mm, as shown in Figure 1.

1.2 steel cylinder 1 bottom processes a movable hinge 4, hinge 4 is fixed on the base 2 by fixed axis 3, and movable hinge 4 pressurizeds can open to salvaging the interior direction of pipe, and hinge 4 radiuses are less than steel cylinder 1 radius, till freely opening, see Fig. 2,3.

1.3 movable hinge 4 is fixed in base 2, base 2 size is consistent with the seamless steel pipe diameter, and height can be about 0.1 m, and steel cylinder welds; In order to make in lifting, install suspension ring 7 additional on salvaging pipe top, see that Fig. 1 shows.

Choose a block plate 1.4 salvage pipe tapping platform, weld at an upper portion thereof two little short columns, stub length is salvaged pipe bottom movable hinge with jack-up and is advisable, and sees among the figure shown in 4.

2. it is up and down to handle the salvaging pipe with the boring tower pulley, and the salvaging step is as follows:

2.1 salvage pipe with the boring tower fixation, transfer downwards, during contact mud face, record mud tube position;

2.2 transfer in the process, when salvaging pipe contact mud, hinge 4 pressurizeds upwards open, mud enters salvages pipe;

2.3 when mud tube is transferred 8m(downwards and salvaged length of tube from recording the position) time, illustrate that mud has been filled to salvage to manage.Make progress this moment to promote and salvage pipe, hinge 4 is closed, and mud is full of to salvage to manage and upwards is promoted to ground;

2.4 after being promoted to ground, will salvaging pipe and be placed in ground salvaging pipe tapping platform, emit mud liquid, finish a salvage;

2.5 the circulation said process continues salvage, until finish.Specifically see shown in Fig. 5,6,7,8.
