Grader for separation of spindle-shaped and long-strip-shaped materials

Abstract

The invention provides a grader for separation of spindle-shaped and long-strip-shaped materials. The grader comprises a feed mechanism, a grading mechanism, an impurity removal mechanism and a dedusting mechanism. The grading mechanism comprises a long strip roller screen and a plurality of grading receiving hoppers located at the bottom of the long strip roller screen. Stone impurity removal hoppers are arranged at the tail ends of the grading receiving hoppers. The impurity removal mechanism comprises an impurity removal blower and an impurity removal hopper on the outer side of the inlet end of the long strip roller screen. A dedusting air opening is formed above the impurity removal hopper relative to an air outlet of an impurity removal blower air channel. The dedusting air opening is connected with a dedusting fan, a cyclone separator and a dust collecting bag sequentially. The other end of the dust collecting bag is connected to the air inlet end of the impurity removal blower. The feed mechanism is provided with a shaking refinder in an inclined state toward a feed inlet of the long strip roller screen. The grader achieves mechanical grading of radix pseudostellariae, integration of dedusting and impurity removal and air direction series connection, thus the effects of energy conservation and emission reduction are achieved, and product grading quality is promoted.

Description

technical field [0001] The invention relates to the technical field of classification and separation equipment, and is particularly suitable for a classification device for separating spindle-shaped and strip-shaped materials, especially for size classification of spindle-shaped varieties such as Radix Pseudostellariae. Background technique [0002] Pseudostellaria Pseudostellariae is the dry tuberous root of the caryophyllaceae plant ginseng. It is slender spindle or slender strip, slightly curved. The surface is gray-yellow to yellow-brown, relatively smooth, with slight longitudinal wrinkles, and fibrous root scars in the depressions. It has the effects of replenishing qi and invigorating the spleen, promoting body fluid and moistening the lungs. It is often used for spleen deficiency, fatigue, loss of appetite, weakness after illness, deficiency of Qi and Yin, spontaneous sweating and thirst, dryness of lung and dry cough. At present, the grading of Pseudostellaria gi...

Problems solved by technology

[0003] The invention provides a classifier for spindle-shaped and long-strip materials, which creates the mechanized classification of Radix Pseudostellariae, overcomes the semi-artificial selection of traditional winnowing machines, and the sizes of the classified Radix Radix Pseudostellariae are not uniform. Repeated winnowing is required to achieve the corresponding grading effect. The loss is large, the efficiency is limited, the floor space is large, it is easily affected by the weather, and the sanitation requirements are not guaranteed. A mechanized grading machine is specially provided, mainly using a long strip sieve. The sieve mesh is classified according to the diameter of the material to be graded, and the materials with different diameters are screened and classified by screens with different pore sizes.
