Filling integrated sewage recovery device for variable pipeline flow plugging simulation test

Abstract

The invention discloses a sewage recovery device for a filling and filling integrated variable pipeline flow plugging simulation test, which belongs to the technical field of sewage treatment. An aggregate recovery bag is fixedly installed on the outside of the aggregate recovery port. The aggregate recovery bag is connected to the recovery tank through a plug-in fixing component. A rotating centrifugal component is installed under the diversion filter component. The invention is scientific and reasonable, and safe and convenient to use. By gradually filtering the sewage containing sand, gravel, slurry and aggregate, the efficiency of recycling and filtering the sewage used for the simulation test of the integrated variable pipeline flow plugging is greatly improved. , At the same time, solid-liquid separation and recovery are effectively realized, making the filtration of sewage more layered, avoiding damage to the entire sewage recovery device caused by sand, gravel and aggregate, and effectively extending the service life of the sewage recovery device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage recovery device for a filling and filling integrated variable pipeline flow plugging simulation test. Background technique [0002] Filling integrated variable pipeline flow plugging refers to the use of grouting prevention and control methods to block groundwater resources in the mining process to avoid pollution and damage to groundwater resources and the environment. Filling integrated variable pipeline flow plugging simulation test It refers to the simulation experiment of the above grouting method, so that the success rate in the actual operation process is higher, but when the plugging simulation test is carried out, due to the use of sand, grout and aggregate to block the pipeline, there will be problems after the test. More sewage, if the sewage is discharged directly, it will not only pollute the environment, but also cause waste of water resources, whi...

[0002] Filling integrated variable pipeline flow plugging refers to the use of grouting prevention and control methods to block groundwater resources in the mining process to avoid pollution and damage to groundwater resources and the environment. Filling integrated variable pipeline flow plugging simulation test It refers to the simulation experiment of the above grouting method, so that the success rate in the actual operation process is higher, but when the plugging simulation test is carried out, due to the use of sand, grout and aggregate to block the pipeline, there will be problems after the test. More sewage, if the sewage is discharged directly, it will not only pollute the environment, but also cause waste of water resources, which does not conform to the concept of green environmental protection in the current society. When recycling the sewage of raw materials, it is only recycled by means of filtration. Since the sewage contains a lot of sand and aggregate, it will cause serious weight burden and damage to the filtering equipment, which greatly reduces the service life of the filtering equipment. Therefore, there is an urgent need for a kind of sewage recovery device for the simulation test of variable pipeline flow plugging to recycle the above-mentioned sewage
