Abstract
The invention relates to a pipe blockage detecting device for paste filling pipelines. The pipe blockage detecting device comprises a lower cylinder body (1), and is characterized in that a piston (3) is arranged in the lower cylinder body (1), sealing rings (2) and guide rings (5) are arranged under the piston (3) which is connected with a piston rod (6), a guide key (9), a limit stop (11), a detection component (10) and a spring (4) are mounted on the piston rod (6), the lower cylinder body (1), a guide flange (7) and an upper cylinder body (8) are connected through bolts, the upper cylinder body (8) is further provided with a measuring switch (12), and a protecting cover (13) used for sealing is arranged at the top of the upper cylinder body (8). The pipe blockage detecting device has the advantages of simple structure, high reliability, no need of perforating the pipelines and low cost, and is particularly suitable for detection of paste filling pipeline blockage.
Description
Technical field
The present invention relates to a kind of pick-up unit of fluid circuit plugging, particularly relate to a kind of pick-up unit of the paste filling pipe plugging for filling mine workplace, belong to paste filling pipe slurry pipeline transport technical field, the length that is applicable to the filling in mine exploitation detects apart from the paste filling pipe plugging.
Background technology
China is the coal production of maximum in the world and the big country of consumption, along with the raising of technology level, in order to liberate " three times ", presses coal, and the filling technique in colliery has obtained great development.But paste body filling is carried non-homogeneous meson, easily plugging, once plugging, whole filling system causes heavy losses.The plugging detection technique is one of difficult point of paste body filling technology.The mode of at present main adopts pressure sensor detects, and when certain section line pressure is elevated to a certain set pressure, thinks that plugging appears in the pipeline of its back.Current common pressure transducer; be difficult to adapt to the flow at high speed of slip in pipeline; for example, and sandstone etc. is easy to the build-up of pressure sensor and can't detect pressure (stone just blocks up the detection mouth that detects original paper; when pressure increases; can't detect force value; as shut down not in time, pipe explosion accident may appear), the wearing quality of pressure transducer is also had relatively high expectations.So common pressure transducer is not suitable for the paste body filling plugging and detects, and its price is more expensive, has increased the input of filling.
Summary of the invention
Purpose of the present invention just is to overcome the prior art above shortcomings, provides a kind of new paste filling pipe plugging pick-up unit.That the present invention has is simple in structure, reliability is high, need not perforate on pipeline, characteristics that cost is low, be particularly suitable for the detection of paste body filling plugging.
The technical solution adopted in the present invention is: this paste filling pipe plugging pick-up unit, include lower cylinder body 1, be characterized in lower cylinder body 1 being provided with piston 3, piston 3 has O-ring seal 2 and guide ring 5, piston 3 is connected with piston rod 6, feather key 9, positive stop 11 are housed on piston rod 6, detect original paper 10 and spring 4, lower cylinder body 1, guide flange 7 and upper cylinder body 8 are bolted, measuring switch 12 also is housed on upper cylinder body 8, and the top of upper cylinder body 8 is provided with the protective cover 13 for sealing.
In technique scheme, the effect of O-ring seal 2 is to prevent that slip from entering cylinder interior; The effect of guide ring 5 is directly contact with cylinder body while preventing piston movement and rub and protect piston and cylinder body not damaged; Spring 4 is parts of core of the present invention, and the decrement by spring is directly proportional to the pressure of conveyance conduit, selects spring according to the pressure of conveyance conduit, thereby detects lotion slip pipeline pressure; Feather key 9 slides in the keyway of guide flange 7, rotates while preventing piston rod movement or is offset; Detect original paper 10 and move upward with piston rod 6, while touching measuring switch 12, report to the police.
Plugging of the present invention detects principle: same section lotion line pressure equates everywhere, when the pressure of carrying in normal range, material flows through in managing, piston 3 is substantially motionless, when pipeline generation plugging, the transfer pipeline increased pressure, line pressure increases to while being greater than spring 4 resistance, slip promotes piston and moves upward, and piston rod 6 moves upward with piston simultaneously, and line pressure further increases, while reaching default pressure, when testing agency touches measuring switch, pressure alarm, detect thereby complete fast the pipeline plugging.
Compared with prior art, the invention has the beneficial effects as follows: for coal mine paste filling pipeline characteristics, realized that the robotization of paste filling pipe plugging detects.By this pick-up unit is installed between transfer pipeline, when plugging appears in the pipeline of pick-up unit back, its pick-up unit place line pressure increases, when line pressure increases to the resistance that is greater than spring, connecting rod moves upward with piston, when link motion touches pick-up unit, send the plugging alerting signal, after outside filling controller collects the plugging alerting signal, automatically stop the filling pump work, guarantee the safety of whole pipeline, by plugging detection alarm position, can judge fast the plugging position, thus quick solution plugging problem.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of pipeline while plugging occurring.
Sequence number in figure: lower cylinder body 1, O-ring seal 2, piston 3, spring 4, guide ring 5, piston rod 6, guide flange 7, upper cylinder body 8, feather key 9, detect original paper 10, positive stop 11, measuring switch 12, protective cover 13.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Fig. 1～Fig. 2, this paste filling pipe plugging pick-up unit, by lower cylinder body 1, O-ring seal 2, piston 3, spring 4, guide ring 5, piston rod 6, guide flange 7, upper cylinder body 8, feather key 9, detect original paper 10, positive stop 11, measuring switch 12, protective cover 13 forms, be provided with piston 3 in wherein said lower cylinder body 1, piston 3 is provided with O-ring seal 2 and guide ring 5, piston 3 is connected with piston rod 6, feather key 9 is housed on piston rod 6, positive stop 11, detect original paper 10 and spring 4, lower cylinder body 1, guide flange 7 and upper cylinder body 8 are bolted, measuring switch 12 also is housed on upper cylinder body 8, the top of upper cylinder body 8 is provided with the protective cover 13 for sealing.
During use, the lower cylinder body 1 of this pick-up unit is installed between transfer pipeline, when plugging appears in the pipeline of pick-up unit back (as Fig. 2), its pick-up unit place line pressure increases, when line pressure increases to the resistance that is greater than spring 4, piston rod 6 moves upward with piston 3, when piston rod 6 motions touch measuring switch 12, send the plugging alerting signal, after outside backfill control system collects the plugging warning, automatically stop the filling pump work, guarantee the safety of whole pipeline, by plugging detection alarm position, judge fast the plugging position, thereby can quick solution plugging problem.
