The pipe blockage detection device of the pipe filled by the paste comprises a lower cylinder body (1) and is characterized in that a piston (3) is arranged in the lower cylinder body (1), a sealing ring (2) and a guide ring (5) are arranged under the piston (3), the piston (3) is connected with a piston rod (6), a guide key (9), a limit stop (11), a detection element (10) and a spring (4) are installed on the piston rod (6), the lower cylinder body (1), a guide flange (7) and an upper cylinder body (8) are connected through bolts, a measuring switch (12) is further installed on the upper cylinder body (8), and a protecting cover (13) for sealing is arranged at the top of the upper cylinder body (8). The pipe blockage detection device of the pipe filled by the paste has the advantages of being simple in structure, high in reliability, low in cost and particularly suitable for detection of paste-filled pipe blockage. No hole needs to be arranged on the pipe.
Description
Technical field
The utility model relates to a kind of pick-up unit of fluid circuit plugging, particularly relate to a kind of paste filling pipe plugging pick-up unit 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 in the world maximum and the big country of consumption, along with the raising of technology level, presses coal in order to liberate " three times ", and the filling technique in colliery has obtained great development.But paste body filling is carried non-homogeneous meson, easily plugging, in case 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; and sandstone etc. is easy to the build-up of pressure sensor and can't detect pressure (stone stifled detection mouth to detecting original paper just for example; when pressure increases; can't detect force value; such as untimely shutdown, 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
The purpose of this utility model just is to overcome the prior art above shortcomings, provides a kind of new paste filling pipe plugging pick-up unit.The utlity model has simple in structure, reliability is high, do not need perforate on pipeline, characteristics that cost is low, is particularly suitable for the detection of paste body filling plugging.
The technical scheme that the utility model adopts is: this paste filling pipe plugging pick-up unit, include lower cylinder body 1, be characterized in being provided with in the lower cylinder body 1 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 the 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 the 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 to contact with cylinder body when preventing piston movement and rub and protect piston and cylinder body not damaged; Spring 4 is parts of the utility model core, and the decrement by spring is directly proportional with 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 when preventing piston rod movement or is offset; Detect original paper 10 and move upward with piston rod 6, when touching measuring switch 12, report to the police.
Plugging of the present utility model 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, when line pressure increases to greater than spring 4 resistance, the slip pushing piston moves upward, and simultaneously piston rod 6 moves upward with piston, and line pressure further increases, when reaching default pressure, when testing agency touched measuring switch, pressure alarm detected thereby finish fast the pipeline plugging.
Compared with prior art, the beneficial effects of the utility model are: 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 the 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 resistance 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of pipeline when plugging occurring.
Sequence number among the 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 detects original paper 10, positive stop 11, measuring switch 12, protective cover 13.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Such as Fig. 1～shown in Figure 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 consists of, be provided with piston 3 in the wherein said lower cylinder body 1, piston 3 is provided with O-ring seal 2 and guide ring 5, and piston 3 is connected with piston rod 6, feather key 9 is housed on the 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, and measuring switch 12 also is housed on the upper cylinder body 8, and 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 the transfer pipeline, when plugging appears in the pipeline of pick-up unit back (such as Fig. 2), its pick-up unit place line pressure increases, when line pressure increases to resistance 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, outside backfill control system stops the filling pump work after collecting the plugging warning automatically, guarantee the safety of whole pipeline, by plugging detection alarm position, judge fast the plugging position, thus can quick solution plugging problem.
