Problems solved by technology

[0002] During the underground operation, it is often necessary to use the water body in the mine to assist the operation. However, the water body in the mine contains a lot of inorganic salts, and the hardness of the water body is generally high. In most of them, the downhole pipeline filter structure is used to filter the water body, but the filter part of the downhole pipeline filter structure is easy to be blocked, and if it is not cleaned in time, the filtering effect on the water body will be affected, and the existing filter structure is inconvenient to disassemble after being blocked. Cleaning is time-consuming and laborious, and even some devices cannot be cleaned and have to be replaced, whic

Embodiment 1

[0018] An underground water supply pipeline filtering device of the present invention is realized in this way, consisting of water inlet pipe (1), water inlet chamber (2), filter core (3), pull ring (4), partition plate (5), main body Shell (6), medium flow chamber (7), filter screen (8), water outlet chamber (9), outlet pipe (10), slot (11), settling tube (12), ramp hole (13) and plugging (14) Composition, the water inlet pipe is connected to one end of the main shell and communicated with each other, the outlet pipe is connected to the other end of the main shell and communicated with each other, and the main shell is a return-shaped pipe that has been bent vertically twice , two settling tubes (12) are vertically placed at the bottom of the main body shell (6), and the two settling tubes (12) are vertically placed at the two bends of the main shell respectively, and the settling tubes (12) and the main body The shells are connected, and the two bends of the main shell are r...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that a plug (14) is placed between one side of the partition plate (5) and the inner wall of the settling tube (12), and a plurality of Inclined hole (13), when in use, the settling tank cooperates with the sedimentation pipe, which can further precipitate and filter impurities in the water and improve the filtering effect;

[0026] The design of the inner filter of the filter element (3) decreases in pore diameter along the direction from the water inlet pipe to the water outlet pipe, which can realize filtering step by step and improve the filtering effect;

[0027] The design of a sealing ring between the filter element (3) and the notch of the slot (11) can prevent water from overflowing from between the filter element (3) and the slot (11);

[0028] The purpose of multi-layer filtering is achieved, the filtering effect is good, and the filter element (3) can be easily disassembled and cleaned.

Abstract

The invention relates to an underground water supply pipeline filtering device and discloses an underground water supply pipeline filtering device for multiple layer filtration. Filtering effect is good and a filter element can be conveniently disassembled and cleaned. A water inlet pipe is communicated with one end of a main shell, a water outlet pipe is communicated with the other end of the main shell, the main shell is a concentric-square-shaped pipe which is vertically bent twice, two settling tubes are vertically arranged at the bottom of the main shell, the two settling pipes are respectively and vertically arranged at two bent parts of the main shell, the settling pipe is communicated with the main shell, partition plates are arranged at the two bent positions of the main shell respectively, the section of the partition plate is T-shaped, the bottom of the partition plate extends into the settling pipe, a certain distance is reserved between the partition plate and the bottom end of the settling pipe, a certain distance is reserved between the partition plate and the inner wall of the settling pipe, the interior of the main shell is divided into a water inlet cavity, a middle flow cavity and a water outlet cavity by the two partition plates, and the water inlet cavity is communicated with the water inlet pipe.

Description

technical field [0001] The invention relates to a filter device for underground water supply pipelines, which relates to a filter device for mine water supply pipelines and belongs to the field of mine equipment. In particular, it relates to an underground water supply pipeline filtering device capable of multi-layer filtering, good filtering effect, and easy to disassemble and clean the filter element. Background technique [0002] During the underground operation, it is often necessary to use the water body in the mine to assist the operation. However, the water body in the mine contains a lot of inorganic salts, and the hardness of the water body is generally high. In most of them, the downhole pipeline filter structure is used to filter the water body, but the filter part of the downhole pipeline filter structure is easy to be blocked, and if it is not cleaned in time, the filtering effect on the water body will be affected, and the existing filter structure is inconveni...
