Abstract

The invention provides a device for preventing a pressure sensor from being solidified and a using method of the device, and belongs to the technical field of paste pipeline conveying. The device comprises a pressure sensor, a tee joint, a four-way joint, a gate valve and pipelines, wherein the gate valve controls the opening and closing states of the pipelines, the pressure sensor is connected with the pipelines, the pipelines are connected through the four-way joint to form the whole device, and the whole device is connected with a slurry pipe through the tee joint. According to the invention, various inconveniences in previous tests are solved, and the pressure in the slurry pipe can be efficiently monitored; and the residual slurry in the pressure sensor can be cleaned while the pressure sensor is not disassembled, so that the experiment precision is ensured while the experiment efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of paste pipeline transportation, in particular to a device for preventing the solidification of a pressure sensor and a use method thereof. Background technique [0002] In recent years, paste filling technology has been gradually adopted by mines due to its advantages of safety, environmental protection, high efficiency and economy. The whole tailings are prepared into high-concentration paste slurry and backfilled to the underground goaf, which not only eliminates the need to build tailings The potential safety hazards brought by the warehouse reduce the pollution to the environment, and can effectively control the ground pressure to ensure the safety of the stope. Therefore, the paste slurry can be efficiently and accurately transported into the stope A key link in body filling. [0003] During the transportation of paste slurry, if the transportation resistance cannot be accurately monitored, it is eas...
