Abstract

The utility model relates to a circular centrifugal jigger which is a separation device for raw ore. The main shape of the circular centrifugal jigger is that the casing of the machine body of an upper part is a cylinder body, and a lower part is composed of a plurality of cones. The shape of the main casing is circular. The technique is characterized in that material is fed along a tangent outer circle by a material inlet 6, and is sorted under the function of centrifugal force; secondly, the process of gravity sorting is that the material enters the air valve 2 of a wind box by a wind feeding pipe 1, and enters an inverted conic wind chamber 10 with a tangent line wind inlet pipe 9 and moves up and down by the air valve 2. A tangent line feeds wind so that medium wind and water move un and down and centrifugally move by a rotational flow mode. So the raw ore is layered according to the density of the material so as to achieve the aim of jigging and sorting.

Description

Circular centrifugal jig

The circular centrifugal jig of the utility model is a kind of centrifugal force, circular centrifugal jig of the produced utility model of gravity compound force field action principle of utilizing.

At present, coal belongs to sieve air cell type and sieve side formula jigging machine down mostly with jigging machine both at home and abroad.The operation principle of two kinds of jigging machines all is identical, and promptly coal carries out layering and sorting by the difference on its density under the effect of fluctuating flow.The utility model centrifugal jig is that housing construction or operation principle all have very big difference.

The purpose of this utility model provides a kind of circular centrifugal jig.It can not only choose low ash cleaned coal from raw material, and can sort metallic ore and nonmetallic ore effectively, deepens to improve lower limit of separation.

Technical scheme

The purpose of this utility model is achieved in that in the body of circular centrifugal jig, and raw material is by feeding mouth 6 feed tangentially, and pan feeding is earlier along the centrifugal rotation of casing 3 inwalls and is contracted to cleaned coal overflow pipe 5 gradually at spiral screen 4 water conservancy diversion and discharges cleaned coal; The material that density is high is thrown to the outer ledge of jigging machine.

Fine grained in the raw material sees through the vertical sieve plate 7 in side and discharges.High-pressure blast is through air inlet pipe 1, do at air-valve 2 and to pump, wind is to enter sieve air chamber 10 down by air inlet pipe 9 tangent lines, make the material bed make the purpose that flow fluctuation up and down reaches gravity preparation by wind action, and centrifugal rotatablely moving is under the synergy of fluctuating flow and centrifugal force, the light material of density is on the upper strata, discharge by overflow pipe 5, density greatly material discharge through circular gate 12 and debris tube 11 in lower floor, promptly finished the process of material layering in circular centrifugal jig, sorting.

What at present, the utility model centrifugal jig was different substantially with the body of traditional jigging machine is: the body fuselage shape of traditional jigging machine all is rectangular, and the body fuselage of centrifugal jig is circular.Compare with traditional jigging machine, its water (flow) direction is a direct current, and the water (flow) direction of the utility model centrifugal jig is to do circular motion under centrifugal action.

The utility model purpose: the utility model centrifugal jig utilizes centrifugal force, gravity compound force field principle of dynamics, and by wind action, pumping reaches gravity concentration in circular body; Reach centrifugal separation by the tangent line pan feeding as centrifugal motion.Therefore, the operating parameter of this centrifugal jig is regulated easily, and separation velocity is accelerated, and the unit disposal ability is improved, and has reached the purpose of the selected utility model of feed coal.

Owing to adopt technique scheme, circular centrifugal jig can sorting composite feed raw coal, again can selected coarse slime, and can decide and wash equipment, can do again and wash equipment again.Not only good separation effect, and floor space is little, saves the factory building space, small investment, and simple in structure, moving component is few, makes easily and keeps in repair.

Beneficial effect: the utility model centrifugal jig is installed and used proof at the scene, and the characteristics of centrifugal jig are: the unit disposal ability is 20t/hm ²More than, can make the coarse slime reclaimer again as the raw coal picking equipment, compare with the common jigging machine of prior art, can get separating effect well.Lower limit of separation can reach 200 meshes.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 2 is a vertical view of the present utility model.

1. air inlet pipe among the figure; 2. air valve; 3. circular body; 4. spiral sieve plate; 5. cleaned coal overflow pipe; 6. feeding mouth (pipe); 7. vertical side sieve plate; 8. sieve plate; 9. blast pipe; 10. air compartment: 11. debris tubes; 12. discharge gate.

The drawing explanation:

In Fig. 1, feeding pipe 6 enters circular body inwall 4 by autofeed or pumping feed and makes the circumference centrifugal motion along tangent line; Pump by air inlet pipe 1 and air-valve 2; Enter air compartment 10 by air inlet pipe 9 along tangent line and make circular motion; Promptly do gravity concentration up and down reciprocatingly by the material above the sieve plate 8; Do the centrifugal force coal separation again, the material layering that density is light is discharged by cleaned coal overflow pipe 5 last.The material fine fraction that density is big can be crossed sieve plate 8 saturating sieve dischargings, and bulky grain is discharged by gate 12.

Fig. 2 is the vertical view of Fig. 1, can see the position of spiral screen plate.

Realize the utility model best way: realize that the best mode of utility model is: the specific design of utility model technical scheme.Shape, structure, effect, the principle of 1 pair of product of accompanying drawing are illustrated, and function has been described, dynamically structure and using method.Make the people understand the circular centrifugal jig operation principle of utility model, parts, the relation that links to each other and can make with reference to drawings clear.This utility model centrifugal jig has been put high coal preparation plant of affair office and has been actually used in production in the Hegang, Heilongjiang Province, and has reached the specific designing requirement of new technique scheme.
