Description
Technical field
The present invention relates to a kind of Three-product teetered bed separator and method of work thereof, specifically sorting is carried out to fine particle stage material, obtain hindered bed separator and its implementation of three different densities stage materials.
Background technology
Hindered bed separator is the separation of coarse slime equipment of being used widely in recent years.Based on hindered falling principle and the fluidized bed principle of maturation, hindered bed separator is designed to cylindricality and square column type more.Tradition hindered bed separator is generally made up of charging gear, waterworks, discharge device and automaton.Material enters in separator, under ascending current effect, form spontaneous fluidized-bed layer.The ore particle that density is less than bed density becomes overflow under ascending current effect, and the particle penetration bed that density is greater than bed density forms underflow, finally completes the separation of weight particle.Selected material only can be divided into the material of two density levels by tradition hindered bed separator, i.e. overflow and underflow.For coal separation, the low ash extract coal that washability is easy choosing, medium optional pan feeding obtains higher yields by traditional hindered bed separator.But for the coarse slime of the difficult choosing of washability, extremely difficult choosing, more owing to closing on thing content, cause separating density not have the effect changing ash content within the specific limits.
For difficulty select material and extremely difficulty select material, intermediate density stage material content is more, and each grade density content is relatively even, carries out sorting can adopt narrow density level sorting to this part material.If carry out secondary sorting to underflow, as shown in Figure 1, namely one section of sorting adopts low-density sorting, and two sections adopt high density sorting, and in tube structure one situation, the underflow that one section of sorting obtains, enters two sections of sortings.If carry out secondary sorting to overflow, as shown in Figure 2, namely one section of sorting adopts low-density sorting, and two sections still adopt less dense sorting, and in tube structure one situation, the overflow that one section of sorting obtains, enters two sections of sortings.That is, from separating density angle, comparatively low-density sorting more easily realizes.
Summary of the invention
Object of the present invention selects material to provide a kind of three mixing technology adopting overflow secondary sorting mode to carry out efficient separation for difficulty choosing, extremely difficulty that intermediate density level content is many just.
Object of the present invention realizes by following technique measures:
A kind of Three-product teetered bed separator of the present invention comprises feeding system, water supply system, separation system, discharge system and accessory system;
A, described separation system comprises one section of sorting chamber and two sections of sorting chambers, described one section of sorting chamber is made up of the inner cylinder hollow cavity arranged with separator main body coaxial line, and the lower end of inner cylinder terminates in the middle and lower part of outer cylinder inner chamber, the upper end of inner cylinder is concordant with the upper end of outer cylinder, the mozzle that internal diameter is greater than inner cylinder external diameter is set with outside inner cylinder, and the lower end of mozzle terminates in above bowl-shape anti whip device that inner cylinder lower end outer wall is fixedly installed, mozzle upper end is higher than the upper end of outer cylinder, lower than the upper mouth being arranged on outer cylinder upper port place overflow launder, described two sections of sorting chambers are made up of the cavity between mozzle and outer cylinder,
