Abstract

The invention discloses an automatic back washing device. The automatic back washing device comprises a filtering module and a water storage and energy storage module which are connected with each other; the filtering module is connected with a medium sampling device; when the pressure in the medium sampling device is larger than that in the filtering module, water in media is filtered out throughthe filtering module and delivered into the water storage and energy storage module to be stored; and when the pressure in the medium sampling device is smaller than that in the filtering module, thestored water is delivered into the medium sampling device through the filtering module by means of the water storage and energy storage module to wash the medium sampling device. Automatic back washing on the medium sampling device is achieved under the condition that no water source exists and power does not need to be supplied by the outside. The invention further discloses a pressure detectionsampling system comprising the automatic back washing device. The medium retention, solidification and blockage phenomena in the medium sampling device are effectively avoided, and medium pressure detection is more stable and more accurate.

Description

technical field [0001] The invention relates to the technical field of high-concentration medium sampling, in particular to an automatic backwashing device and a pressure detection sampling system including the device. Background technique [0002] With the rapid development of my country's iron and steel industry, many mining (steel) enterprises have long-distance pipelines to transport high-concentration slurry, so there are problems of leakage and leak point inspection. Pressure detection is used to judge leakage and leak point inspection in pipeline transportation. This method has many advantages, but it also has its disadvantages, that is, the pressure detection sampling system is prone to stagnation, solidification, and blockage when production is stopped or decompressed. The pressure detection sampling system is generally a short sampling pipe with a flange or is composed of a short sampling pipe, a cut-off ball valve, and a flange. After the pipeline transport of pulp...
