Fluid differential separator

Abstract

The invention provides a liquid differential grader which is characterized by comprising a mixing bin provided with a feed inlet, a liquid outlet and a cone opening at the upper part, an equalizing bin provided with a liquid inlet, a liquid-outlet feed inlet and a discharge port at the lower part, and a separation tube for connecting the cone opening of the mixing bin and the liquid-outlet feed inlet of the equalizing bin. In the invention, solid particles can be suspended by the liquid flowing upwards to reduce the mutual friction among the solid particles so that the solid particles can move freely; and under the action of gravity, the high-mass solid particles can be sunk and finally discharged by overcoming the upflow resistance of the liquid, while the low-mass solid particles are difficult to be sunk owing to failure in overcoming the upflow resistance of the liquid, therefore, the solid particles with different mass can be separated completely under an operating condition of uniform liquid distribution by simple structural composition and the separated liquid can be recycled after sedimentation and simple treatment, thus avoiding environmental pollution, achieving good grading effect and high separation efficiency, saving energy, and being suitable for grading the particles with various density and different mass.

Description

technical field [0001] The invention relates to a separator, in particular to a separator for hydraulically separating solid particles, and belongs to the technical field of design and manufacture of solid particle separation equipment. Background technique [0002] Most of the existing hydraulic solid particle classifiers are mechanical agitation hydraulic classifiers, which need to be equipped with a power device, which not only consumes electric energy, but also has a large volume, occupies an area, and is difficult to configure. The sieve plate type trough hydraulic classifier, also known as the Denver type hydraulic classifier, is a special equipment for separating solid particles of different qualities by using the interference and sedimentation conditions caused by the sieve plate. It is often used as a pulp separation equipment for mineral processing industry. It is a conical body with a cavity. The vertically arranged partitions are used to divide the cavity into 4...

Problems solved by technology

However, this kind of sieve plate hydraulic classifier often causes secondary reflux agitation due to the uneven distribution of rising water velocity, or the number of sieve holes, or the size of the sieve hole diameter, which ultimately affects the classification effect and classification rate, and even makes it difficult to continue the classification.
