Filling strainer pipe

Abstract

A filling strainer pipe comprises a longitudinally arranged strainer pipe body and a steel wire rope, wherein the steel wire rope is located inside the strainer pipe body, the upper end and lower end of the strainer pipe body are respectively provided with a steel wire rope clip and a chuck in sequence, and a limiter is arranged inside the strainer pipe body; each chuck comprises a first limiting ring and an upper supporting ring; the limiter comprises a second limiting ring and a third limiting ring, and the steel wire rope penetrates through the first limiting ring and the upper supporting ring of the chuck at the upper end of the strainer pipe body, the second limiting ring and the third limiting ring of the limiter, and the upper supporting ring and the first limiting ring of the chuck at the lower end of the strainer pipe body in sequence; the upper end of the steel wire rope is clamped through the steel wire rope clip at the upper end of the strainer pipe body, and the lower end of the steel wire rope is clamped through the steel wire rope clip at the lower end of the strainer pipe body. The filling strainer pipe is simple in structure, convenient and quick to install, high in safety performance, long in service life, low in cost, and good in water filtration effect.

Description

technical field [0001] The invention relates to mine goaf filling technology, in particular to a filling filter pipe. Background technique [0002] Mine goaf is the underground empty area left after mining. If it is not filled, it will cause the ground to collapse and bring danger. Filling mining is to fill the goaf with filling materials underground or on the ground, which can control surface subsidence, eliminate unsafe factors, and improve resource recovery rate. [0003] In the research process of filling technology, in order to discharge as much free water in the filling slurry as possible, it is often necessary to install a water filter pipe to achieve the purpose of rapid water filtration and avoid slurry running, thereby improving drainage efficiency and eliminating potential safety hazards . Therefore, it is necessary to take appropriate technical measures to quickly and conveniently drain the filling slurry in the goaf filling of mines. [0004] When different d...

Problems solved by technology

In general, in order to improve the efficiency of water filtration and ensure the effect of water filtration, bellows are sometimes used as water filter pipes. When bellows are used as water filter pipes, both sides of the entire pipe need to be reinforced with steel wire ropes. The processing procedure is cumbersome and the consumption of steel wire ropes is relatively high And it is not recyclable; every other section of the external steel wire rope needs to be fixed with pipe clips, which is time-consuming and labor-intensive, and the cost is high; when installing the water filter pipe, the external steel wire rope is easy to scratch with the outside world, which affects the speed of the operator to install the water filter pipe

[0005] Sometimes, ordinary plastic pipes are also used as water filter pipes. When ordinary plastic pipes are used as water filter pipes, steel wire rope reinforcement is not required, but ordinary plastic pipes have low water filtration efficiency due to their small cross-sections; in order to solve the problem of low water filtration efficiency, Sometimes holes are drilled in the pipe wall or ordinary plastic pipes with larger diameters are used. If too many holes are drilled in the pipe wall, the ordinary plastic pipes may be broken due to the lack of steel wire rope reinforcement. If ordinary plastic pipes with larger diameters are used, Ordinary plastic pipes with larger diameters are difficult to straighten completely and are easy to curl, which reduces the water filtration efficiency and is more difficult to install, which will greatly affect the water filtration effect, and it is difficult to guarantee the operation safety
