Abstract

The utility model provides a dry vertical spiral bean separator for separating impurities in beans by utilizing gravity and centrifugal action.

The main working part of the machine is provided with a feeding hopper and a rectifying hopper which are fixed on a bracket; the flow dividing cap, the spiral inner and outer slideways, the discharge ports of the certified products and the defective products and the discharge ports of the impurities are all fixed on the mandrel; the bracket and the mandrel are vertically arranged on the base frame and covered in the outer cover. The beans to be sorted are sent into the feeding hopper by a spiral lifting mechanism (or manually), then freely fall onto the shunting cap, and are sorted along the spiral inner and outer slideways by the rectifying hopper. The machine occupies less land, is convenient to operate, saves labor and energy, has high impurity removal rate and has no noise pollution.

Description

Vertical spiral bean sorter

The utility model provides a kind of dry method cull eliminator that utilizes gravity to separate impurity in the beans with centrifugal action.

The screening installation of beans mainly contains vibratory sieve, the sorting of suction (blowing) wind formula, ladder chute, horizontal spiral sorting at present, wherein vibratory sieve, the sorting of suction (blowing) wind formula are dry separations, ladder chute, horizontal spiral sorting are wet splits, but all there is sorting cost height, impurities removing efficiency is low, loss is big, and noise is big, shortcomings such as contaminated environment.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of shunting cap that has is provided, the inside and outside slideway structure device of the vertical multi-layer spiral of rectification bucket, and it can isolate the impurity in the beans rapidly, and sorting is thorough, efficiency of separation height.

The utility model purpose is achieved like this, make the vertical direction spiral motion as particle, the linear velocity of motion is big more, suffered centrifugal action is just big more, but just different as the suffered resistance of different suffered gravity of the proportion of granular materials and motion on flight, beans mainly are to roll on flight, frictional resistance is little, acceleration is big, and it is big that the movement velocity value increases, and keeping screw needs centripetal force also big; Impurity mainly is to slide on flight, frictional resistance is big, acceleration is little, it is little that the movement velocity value increases, keeping screw needs centripetal force little, and the centripetal force that beans obtain when mixing on flight motion is different, and the centripetal force that impurity obtains can be kept its motion in spiral, and the centripetal force deficiency that beans obtain just breaks away from spiral and makes centrifugal motion.

This device is finished according to above-mentioned idea design, see accompanying drawing 1, be vertical helical bean sorter schematic diagram, beans and impurity rise to elevating hopper 8 by feed hopper 4 through spiral, again through shunting cap 9 with rectification bucket 10 enters into helical form

inner slide

12 and 13 of helical form external slideway are downward for the helical movement, impurity such as dust, skin of beancurd flows out from impurity outlet 19 as a result, and particles such as soil block, rubble, broken beans flow out from substandard products discharging opening 17, and whole grain soybean is flowed out from certified products discharging opening 16.

Wherein the helical form inner slide is made up of four identical spirals, their aligning method is to add a slice along the every half-twist of helical axis interval P distance, general P sees accompanying drawing 2 at 10-50mm(), the helical form external slideway has only a slice, but the baffle plate of holding up (seeing accompanying drawing 3) is arranged on the external diameter, the pitch of helical form external slideway must be less than 2/3 of helical form external slideway outer diameter D with the helical angle and the outside diameter d identical, the helical form inner slide of helical form inner slide, and the helixangle of external slideway flight is advisable at 30 °-60 ° in the helical form.

Shunting cap 9(sees accompanying drawing 4) to form by a cone and column, the cone angle of cone is at 90 °---and be advisable in 150 ° of scopes, be threaded on the column and can adjust cone up and down, adjustment height is 0---80mm(sees accompanying drawing 4).

But adjust the helical angle of external slideway in the helical form and cone angle and the cone and the upper and lower different types of bean or pea of distance sorting of rectification bucket of cone, as red bean, mung bean etc.

Elevating hopper 8, rectification bucket 10 all are fixed on the support.Shunting cap 9, helical form inner slide 12, helical form external slideway 13 all is fixed on the helical axis core 11.Sorting working portions such as elevating hopper 8 shunting caps 9, rectification bucket 10, helical form inner slide 12, helical form external slideway 13, helical axis core 11, support 14 are all in outer cover 18, to prevent dust and the influence that weakens NOISE ON ENVIRONMENT.

This equipment has cheap, and is simple in structure, time saving and energy saving, the impurities removing efficiency height, good separation effect, power consumption less, advantage such as pollution-free.

Below in conjunction with specific embodiment (seeing shown in the accompanying drawing 1) each concrete structure of bean sorter is described: 1. underframe 2. motors 3. decelerators 4. storage bin(hopper)s 5. material loading helical axis 6. material loading spiral urceolus 7. discharging openings 8. elevating hoppers 9. shunting caps 10. rectification buckets 11. mandrels 12. helical form inner slide sea whelks 13. helical form external slideway sea whelks 14. peripheral boards 15. supports 16. certified products discharging openings 17. substandard products discharging openings 18. outer covers 19. sundry goods discharging openings 20. castors.Be the bean sorter parameter of sorting soya bean below:

The inside and outside slideway pitch of helical form t is 240mm, and helixangle is 45 °

Helical form inner slide spiral outside diameter d 230mm, arrangement pitch p is 35mm.

Helical form external slideway spiral outer diameter D 450mm.

It is 10mm with the vertical distance of rectification bucket discharging opening that shunting cap tapering α is 120 °.

Soya bean sorting amount can reach 1 ton/hour.

Impurities removing efficiency＞98%.
