The application makes the discovery of following facts and problem and understanding based on inventor：

Concentrator in the relevant technologies, the single straight-through straight tube of generally use add flocculant into chute and feedwell, so And when the flow for entering the ore pulp in chute and feedwell is larger, it is in direct contact in the flow area of ore pulp with flocculant Ore pulp shared by area it is smaller, that is to say, that the larger ore pulp of flow cannot come into full contact with flocculant, cause ore pulp with wadding Solidifying agent contact, the chance of mixed coalescence into wadding core or floc sedimentation are few, especially for large-scale concentrator, ore pulp and flocculant it is mixed It is worse to close effect, flocculating effect, so as to influence the settling efficiency of concentrator.

For this purpose, present applicant proposes a kind of feeding mechanisms for concentrator that can improve the pockets of efficiency of ore pulp flocculation 10。

Below with reference to the accompanying drawings the feeding mechanism 10 for concentrator of the utility model first aspect embodiment is described.

As shown in Fig. 1-Fig. 9, according to the feeding mechanism 10 for concentrator of the utility model embodiment, including：Feed Well 200, chute 100 and multiple flocculant distributors 300.

Specifically, feedwell 200 has feed chamber.Chute 100 is located in feedwell 200, and chute 100 and feed chamber Connection enters feed chamber after the transport that ore pulp passes through chute 100.Multiple flocculant distributors 300 are respectively provided at 200 He of feedwell In chute 100, each flocculant distributor 300 includes：Manifold 310 and multiple branch pipes 320.Multiple branch pipes 320 are located at manifold 310 On, and multiple branch pipes 320 are distributed along the axially spaced-apart of manifold 310, each branch pipe 320 is connected with manifold 310, and each branch pipe 320 have multiple discharge holes 321.

For example, the central axis of the manifold 310 of each flocculant distributor 300 is vertically oriented, multiple branch pipes 320 It is vertically spaced apart, in this way, the ore pulp in the manifold 310 of each flocculant distributor 300 is distinguished by discharge hole 321 Flocculant is sprayed into chute 100 and feedwell 200, specifically, each flocculant distributor 300 is conveyed by manifold 310 To each branch pipe 320, flocculant flows out flocculant from the discharge hole 321 on branch pipe 320.

In this way, the arrangement of multiple discharge holes 321 on multiple branch pipes 320 and branch pipe 320 so that no matter in transverse direction (example Such as horizontal direction) on or longitudinal direction (such as vertical direction) on can supply into chute 100 and feedwell 200 uniformly and stabilization Flocculant, here, laterally include the width direction of chute 100 and the radial direction of feedwell 200, longitudinal direction includes the depth of chute 100 Spend the axial direction of direction and feedwell 200.That is, in the entire flow area of ore pulp, ore pulp can be abundant with flocculant It contacts to be mixed into wadding core.

It should be noted that the flow area of ore pulp is referred to perpendicular to the section of the flow direction of ore pulp, for example, slipping In slot 100 flow area of ore pulp be perpendicular to chute 100 feedstock direction (when chute 100 is horizontal positioned, chute 100 Feedstock direction is horizontal direction) section, the flow area of ore pulp is be parallel to feedwell 200 axial in feedwell 200 Section.

Further, since flocculant distributor 300 is set respectively in chute 100 and feedwell 200, in this way, being flowed by chute 100 It when the ore pulp gone out rotates in feedwell 200, can be contacted again with flocculant, repeatedly flocculation makes the flocculation of ore pulp unite chance It greatly increases.
