This internal two - stage swirler that is equipped with of swirler, the drum part comprises upper portion and lower part, wherein two - stage swirler tilting fixed is on the upper portion of swirler drum. The utility model discloses a design of two -stage swirler, two - stage swirler's inlet pipe links to each other with the overflow pipe of one -level swirler, the material gets into one -level swirler by total pan feeding pipe, the result that density is big is discharged as the product from failing from one -level swirler underflow opening, the result that density is little gets into two - stage swirler through one -level swirler overflow pipe, the slightly little result of its middle density is again from the two - stage swirler overflow pipe drum upper portion of discharging, because drum upper portion is seal structure, the result is full of the back with drum upper portion and discharges from the export of swirler concentrate and regard as the concentrate result, the result that density is big is slightly discharged as the chats result through the two - stage swirler underflow opening to having been divided into three kinds of products by the ore dressing thing, the purpose that three products selected separately has been realized. This device has adopted swirler ontology built -in two - stage swirler structure, has not only realized the sorting of three kinds of products of mineral, has improved the precision of selecting separately, has reduced area moreover, simple structure, convenient operation.

Description

Three products heavy medium cyclone

Technical field

This utility model relates to a kind of cyclone for sorting, particularly to a kind of three products heavy medium cyclone.

Background technology

The three products heavy medium cyclone structure that existing factory uses is complicated, and the area that takes up room is big, and sharpness of separation is relatively low, and cost of investment is higher, gives to install and use and brings a lot of inconvenience.And the three products heavy medium cyclone described by this utility model is to be provided with a second cyclone in the inside of one-level cyclone, and second cyclone is to tilt to be fixed on cyclone cylinder top, this design had both reduced the abrasion to second cyclone of the bulky grain in material, the most also have easy for installation, area occupied is little and sharpness of separation advantages of higher, has good market prospect.

Summary of the invention

Goal of the invention of the present utility model is for existing heavy medium cyclone sharpness of separation low, inconvenience is installed, take up an area absolutely empty the shortcoming such as big, it is provided that tilting in a kind of cyclone body fix a second cyclone, can realize sorting the three products heavy medium cyclone of three kinds of different products simultaneously.

Realize above-mentioned purpose by the following technical solutions:

A kind of three products heavy medium cyclone, this cyclone includes total feeding pipe, cylinder, bores section, and second cyclone, mine tailing export, and chats outlet and concentrate export.Being provided with second cyclone in described cyclone body, wherein cylindrical portions is made up of with bottom top.

The tilting top being fixed on cyclone cylindrical portions of described second cyclone.

In described cyclone, the overflow pipe of one-level cyclone is connected with the feed pipe of second cyclone.

Described cylinder upper part is provided with concentrate outlet and chats exports, and cylinder lower part connects with feeding pipe, and cone pars infrasegmentalis is provided with mine tailing outlet.

This utility model uses technique scheme, compared with prior art, its remarkable result is: owing to using two cyclone design, the feed pipe of second cyclone is connected with the overflow pipe of one-level cyclone, material is entered cyclone by total feeding pipe, the product that density is big is discharged from one-level cyclone underflow opening, the product that density is little enters second cyclone through one-level cyclone overflow pipe and again sorts, the product of density minimum is discharged to cylinder top from second cyclone overflow pipe, until discharging from the outlet of cyclone concentrate after being full of cylinder top, the slightly larger product of density is discharged through second cyclone underflow opening, thus selected mineral be divide into three kinds of products, achieve the purpose of tertiary industry sorting.This device have employed cyclone body built-in second cyclone structure and not only achieves the sorting of mineral three products, and decreases floor space, and simple in construction is easy to operate.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

In figure, labelling is as follows: mine tailing outlet 1, cone section 2, total feeding pipe 3, cylinder 4, second cyclone 5, chats outlet 6, concentrate outlet 7.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described.

The utility model discloses a kind of three products heavy medium cyclone, its design philosophy is: fix a second cyclone in cyclone body cylinder upper angled, and the overflow to one-level cyclone sorts again, thus realizes the purpose of three products sorting.

This three products heavy medium cyclone body is cylinder 4 and circular cone 2 structure, and cylinder 4 is divided into upper and lower two parts, tilting inside cylinder top fixes a second cyclone.Use this structure, it is possible to use the suspension of a kind of density sub-elects three kinds of different densities products simultaneously.

Cylindrical structure top is provided with concentrate outlet 7, and the side of nozzle is provided with chats outlet 6.Cylindrical structure bottom connects with feeding pipe 3.Cone pars infrasegmentalis is provided with mine tailing outlet 1.The cylinder of cyclone body is divided into two parts by this utility model, and cylinder upper part tilts to fix a second cyclone 5, and cylinder upper and lower part is only connected with one-level cyclone overflow pipe, and the overflow pipe of one-level cyclone is as the feed pipe of second cyclone.One-level cyclone overflow can be again broken down into two kinds of different products of density by this set, thus reaches the purpose of three products sorting.

Operation principle of the present utility model:

See Fig. 1, when material and suspension tangentially feed cyclone with certain pressure, material starts to form the external spiral stream declined along cyclone cylinder bottom from total feeding pipe 3, and one internal coiling stream risen it is formed about in cyclone axle center, owing to centrifugal action is at cyclone axle center formation air column, material can be layered along with the difference of density, under density maximum product flows to external spiral, from mine tailing outlet 1 discharge.The product that density is lighter flows to internal coiling, it is discharged into built-in second cyclone 5 charging aperture from one-level cyclone overfall, then one section of overflow product is again built second cyclone 5 and is divided into the product of two kinds of different densities, the little material of density is through concentrate outlet 7 discharge, and the slightly larger material of density is via chats outlet 6 discharge.Thus selected mineral be divide into three kinds of products, it is achieved that the purpose of tertiary industry sorting.

Claims (2)

1. three products heavy medium cyclone, it is characterised in that: being provided with second cyclone in described cyclone body, cylindrical portions is top and bottom, and two parts are connected by one-level cyclone overflow pipe, and one-level cyclone overflow pipe is as second cyclone feed pipe.

Three products heavy medium cyclone the most according to claim 1, it is characterised in that: described second cyclone tilts to be fixed on the upper part of cylinder.
