Abstract
The invention discloses a streaming assistant-selection jigging sorting method. A streaming device is additionally arranged in a bed layer so as to generate a local streaming area and streaming motion, a horizontally flowing water flow generates negative pressure in a tail flow area of a streaming motion plane, so that a part of relatively heavy sorted materials is gathered in the area, the horizontally flowing water flow generates a local loosing area in the tail flow area of the streaming motion plane, and accordingly local loose degree of the bed layer is improved. When the streaming assistant-selection jigging sorting method is used for sorting ores or coal, effects of improving sorting precision and a sorting lower limit can be obtained, water consumption is further reduced, processing quantity is increased, and the streaming assistant-selection jigging sorting method is brand-new and is particularly applicable to jigging sorting of high slack coal.
Description
Affiliated technical field
The present invention relates to a kind of jigging method for separating, especially relate to a kind of stream to help select the jigging method for separating.
Background technology
At present; In the air impulsive motion jigging method for separating both domestic and external; The motion of jig bed mainly by under fluctuating flow effect up and down move up and down and two kinds of basic exercises of horizontal movement under the bottom horizontal flow sheet flow action are formed; Wherein moving up and down of bed accomplished by the sorting work of sorting material, and horizontal movement has then mainly been born by the horizontal transport of sorting material.This method becomes always from the production practices of this method generation last 100 years till now; But along with the expansion of the scope of application, along with further raising to jigging efficient; When particularly using this method that thin material is carried out the jigging sorting; Find that there is following problem in this method: 1. surface water laminar flow speed is big, and the thin material of a part flows in superficial water, does not obtain sorting; 2. water consumption is big, and the little meeting of the water yield brings porosity of jig bed not enough, has influence on the sharpness of separation of this method; When 3. duff content was too much, bed top was prone to harden, and the upper strata sorting is bad; 4. the comprehensive dressing lower limit can only reach 0.5mm; 5. the flowing water flow energy is not participated in sorting.These problems make this method use and are restricted that the sharpness of separation and the lower limit that have influenced this method further improve.
