Abstract
The invention discloses a superfine high-density slurry suction filtration experiment system and an implementation method, which are characterized in that in the implementation process of the experiment system, a geotechnical cloth clamp is connected with a vacuum kettle through a hose, the vacuum kettle is connected with a vacuum pump through an air pipe, and a suction filtration experiment is carried out on high-concentration tailing slurry. The geotechnical cloth clamp is a carrier of the geotechnical cloth and a connecting part of a suction filtration pipeline of the experimental system, and can be used for testing the reverse filtration performance and the drainage performance of different geotechnical cloths under different types of tailings, different tailings concentrations and different vacuum pressures; meanwhile, the vacuum kettle and the electronic scale are used in combination, and the change characteristics of the clogging process and the filtrate along with time can be researched by means of the high-definition camera. According to the invention, a new idea is provided for solving the problems of unclear clogging mechanism, unclear filter cake production efficiency and the like in the traditional tailing suction filtration experiment.
Description
Technical field [0001] The present invention relates to an ultrafine high density concentration slurry filtering experiment system and implementation method can be widely used in tailings processing, metallurgy, coal, chemical, pharmaceutical food, environmental protection, thermal power plant, coal treatment, sewage treatment and other industries. Background technique [0002] The filtration is an important construction method and auxiliary means during tailings treatment. However, with the improvement of the mineral indicators, the average particle size of the current tailings is reduced, and the ultra-fine tailing method is concentrated and dehydrated when using the filtration method, and the filter cloth is more easy to silly. Blocking. [0003] The silt has always been the focus of the study in the process of tail mining, and the observation and research of the silty blocking mechanism of the geotextile, and the observation and research of filter cake is the focus of scholar...
