Three-product teetered bed separator

Abstract

The invention relates to a three-product teetered bed separator, which comprises a separating device, a feeding device, an overflow device, an inner backwater device, an outer backwater device, a control system and a discharging device; the control system controls the running of all devices, the separating device comprises an inner barrel and an outer barrel, the feeding device sends material into the inner barrel, the inner backwater device ensures that water moves upwards from the bottom part of the inner barrel so as to form a first interference layer with the material which is sent by the feeding device, the material which is precipitated through the first interference layer is discharged from the discharging device on the bottom part of the inner barrel, and the material which moves to the top through the first interference layer enters the outer barrel; and the outer backwater device ensures that the water moves upwards from the bottom part of the outer barrel so as to form a second interference layer with the material inside the outer barrel, the material which is precipitated through the second interference layer is discharged through the discharging device on the bottom part of the outer barrel, and the material moves to the top part of the outer barrel through the second interference layer automatically flows into the overflow device to be collected. The three-product teetered bed separator is used for separating superfine particle swarms to obtain three products, the separation precision is greatly improved, and the controllability of the product quality is strengthened.

Description

technical field [0001] The invention relates to a hydraulic classification equipment, in particular to a three-product interference bed sorter. Background technique [0002] The traditional disturbed bed separator is a kind of hydraulic grading equipment using water as the medium. The disturbed bed sorter is a square or circular tank. Water is introduced into the tank from the bottom to flow upwards. The material is fed from the upper center of the tank. The fast-settling particles are discharged from the discharge port at the bottom, and the rising water carries light and fine particles. Spills flow upward and are collected as overflow product. After the sorted material enters the barrel, it interferes and settles according to its own particle size and density. The difference between the respective settling velocity and the rising water velocity forms different flow directions up and down, and the material group whose settling velocity is close to the rising water velocity...

Problems solved by technology

Therefore, this equipment can only divide the material to be sorted into two products at the same time, that is, the overflow product and the underflow product. At this time, the difficulty of sorting increases and the sorting accuracy decreases. At this time, the two products of overflow and underflow will inevitably make this part of the intermediate density material be randomly distributed to the overflow or underflow, which will cause either the ash content of the overflow product to increase or Reduced ash content in underflow product, resulting in loss of efficiency
