Underground water supply pipeline filtering device

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...

[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, which increases the operating cost

[0003] Notification number CN206391707U discloses a water supply pipeline filter device with self-checking alarm function, including a connecting cylinder with flanges at both ends, one end of the connecting cylinder is provided with a water inlet, and the other end of the connecting cylinder is provided with a water outlet , a filter screen and a pressure sensor are arranged in the middle of the connecting cylinder, and the side of the filter screen close to the water outlet is offset against the pressure sensor, and the pressure sensor is connected with an alarm. After the filter screen in the device is blocked, it is not convenient to filter Net disassembly and cleaning
