Problems solved by technology

[0004] The current powder classifier is mainly used for sorting through the cooperation of the filter screen. When the filter screen is set vertically, the time for the powder to contact the filter screen is short, and it is difficult to sort out. When the equipment is horizontal, it is easy to cause the powder to Accumulation, thus affecting the efficiency of powder selection, so it needs to be optimized

Embodiment 1

[0024] Such as figure 1 , 2 . The powder separator for mines shown in 3 includes an outer shell 1, the bottom of the outer shell 1 is fixedly equipped with a fine powder discharge pipe 4, and the outer side of the fine powder discharge pipe 4 is fixed with the outer shell 1. The connected support column 3, the outer shell 1 is provided with an inner shell 2, the bottom of the inner shell 2 is fixedly installed with a coarse powder discharge pipe 5, and the coarse powder discharge pipe 5 runs through the bottom of the outer shell 1 And extend to the outside, that is, through the cooperation of the inner shell 2 and the outer shell 1, and through the cooperation of the coarse powder discharge pipe 5 and the fine powder discharge pipe 4, the coarse and fine powder separation of the ore is realized, and the ore after the powder separation is cleaned for convenience. out, the bottom of the outer casing 1 is a conical structure, so as to avoid the accumulation of fine powder and ca...

Embodiment 2

[0029] This embodiment is further optimized on the basis of embodiment 1, as Figure 4 As shown, the coarse powder discharge pipe 5 includes a hopper 20 and a spiral cylinder 21, the hopper 20 is fixedly installed at the bottom of the filter cartridge 10, and the spiral cylinder 21 is fixedly connected to the bottom of the hopper 20 through the material connection pipe 22 , that is, the unselected coarse powder falls into the bottom of the filter cartridge 10, and is collected by the receiving hopper 10, and sent from the receiving pipe 22 to the spiral cylinder 21; the surface of the spiral cylinder 21 is provided with a plurality of sorting holes 24, That is, the material passing through the spiral cylinder 21, under the action of centrifugal force, throws out the remaining fine powder that may remain, and realizes complete separation; the bottom of the spiral cylinder 21 is fixedly installed with a discharge pipe 23 communicating with it. The lower end of the material tube ...

Abstract

The invention relates to a powder concentrator for mines, and belongs to the technical field of mining equipment. The powder concentrator comprises an outer shell, wherein a fine powder discharge pipeis fixedly arranged at the bottom of the outer shell, a support column fixedly connected to the outer shell is arranged on the outer side of the fine powder discharge pipe, an inner shell is sleevedwith the outer shell, a coarse powder discharge pipe is fixedly arranged at the bottom of the inner shell, the coarse powder discharge pipe penetrates through the bottom of the outer shell and extendsto the outside, a sorting mechanism rotationally connected to the inner shell is arranged in the inner shell, the upper end of the sorting mechanism penetrates through the outer shell and extends tothe outside, and a driving mechanism used for driving the sorting mechanism to rotate is fixedly arranged on the side face of the outer shell, a feeding pipe is fixedly arranged on the upper end of the outer shell, and the lower end of the feeding pipe extends into the inner shell; According to the powder concentrator for mines, the sorting path is prolonged, the sorting effect is improved, a packing auger is synchronously driven to work to realize continuous feeding, in addition, thorough separation is realized under the cooperation of a centrifugal separation effect, and the powder sorting efficiency is improved; and therefore, the powder concentrator for mines is more efficient and practical.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a powder separator used in mines. Background technique [0002] Mine refers to an independent production and operation unit that extracts ore with a certain mining boundary. Mine mainly includes one or more mining workshops (or pitheads, mine shafts, open pits, etc.) and some auxiliary workshops, and most mines also include ore dressing plants (coal washing plants). Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. According to the different stope management methods in the process of ore mining, non-coal underground mining methods can be divided into: empty stop mining method, caving mining method, and filling mining method. Mining can be carried out according to specific conditions, but no matter which mining method is used It is inseparable from the support of mining equipment. [0003] Mining equipment include...
