Embodiment 1

[0034] This embodiment provides a variable-diameter, variable-intercept spiral sorting mechanism, such as figure 1 As shown, it includes a central column 4, a spiral sorting sheet, a feed port 1 and a discharge port 5, wherein the spiral sorting sheet is spirally arranged on the outer wall of the central column 4; the feed port 1 is arranged on The upper part of the central column 4, the discharge port 5 is arranged at the bottom of the central column 4; the upper surface of the spiral sorting sheet is formed with a spiral sorting groove along the length direction of the spiral sorting sheet, and the The upper end of the spiral sorting tank is connected with the feed inlet 4, and the lower end is connected with the discharge port 5; the spiral sorting tank includes a variable-diameter spiral sorting tank part 2 and a variable-intercept spiral sorting tank part 3 , and the variable-diameter spiral sorting groove part 2 is located above the variable-intercept spiral sorting groo...

Embodiment 2

[0041] The variable-diameter, variable-intercept spiral sorting mechanism that present embodiment provides, such as image 3 As shown, the number of spiral sorting sheets is two, and the two spiral sorting sheets are wound on the central column 4 at intervals, and the two feeding ports 1 corresponding to the two spiral sorting sheets are arranged up and down. In this embodiment, the structures and connections of other parts are the same as those in Embodiment 1, and will not be described in detail in this embodiment.

Embodiment 3

[0043] This embodiment provides a spiral separator, such as Figure 4 and Figure 5 shown. The spiral separator comprises a mounting bracket 6, a feed distributor 7 and a shunt pipe 8, the feed distributor 7 is fixedly installed on the top of the installation bracket 6, and one end of the shunt pipe 8 is connected to the feed distributor 7 The bottom outlet is connected, the other end of the shunt pipe 8 is connected to the feed port 1, and the central column 4 is vertically fixed on the mounting bracket 6.

[0044] Such as Figure 4 and Figure 5 As shown, the number of the spiral sorting sheet and the shunt pipe 8 are equal and multiple (two are shown in the figure, and there can be more according to actual needs), each of the spiral sorting sheets passes through a The root shunt pipe 8 is connected with the bottom outlet of the feed distributor 7 .

[0045] The quantity of the spiral sorting mechanism in each described spiral sorter among the figure can be set, Figur...

Abstract

In the variable-diameter, variable-intercept spiral sorting mechanism provided by the present invention, the upper surface of the spiral sorting piece is formed with a spiral sorting groove along the length direction of the spiral sorting piece, and the spiral sorting groove includes a diameter-changing groove located above The spiral sorting groove part and the variable intercept spiral sorting groove part located below, the inner diameter of each circle of the variable diameter spiral sorting groove part increases sequentially from top to bottom, and the water flow moves in the sorting grooves with different diameters , so that the material is subjected to a relatively large disturbance, which can strengthen the layering and zoning effect of different quality materials; the ratio of the pitch of each circle of the variable intercept spiral sorting groove to the inner diameter of the corresponding circle increases sequentially from top to bottom, so that Partially stratified materials through the variable-diameter spiral sorting tank can be subjected to greater centrifugal force and water flow after entering the variable-intercept spiral sorting tank, which can strengthen the sorting speed of materials and improve the processing capacity of the equipment.

Description

technical field [0001] The invention relates to a spiral sorting device used in a coal preparation plant, in particular to a variable-diameter and variable-intercept spiral sorting mechanism. Background technique [0002] Coal is an important energy and the basic energy for the continuous progress and development of human society. In the raw coal mining production process, a large amount of primary coal slime will be produced. After the primary coal slime passes through a classifying cyclone group, a spiral separator, a high-frequency fine screen and a coal slime centrifuge, the coarse and refined coal slime product is finally obtained. Among them, the spiral separator is a sorting equipment for sorting fine-grained coal, and its sorting effect directly affects the clean coal ash and clean coal recovery rate of the final clean coal slime product. Therefore, a good spiral separator can not only increase the recovery rate of coal, but also reduce the grayness of clean coal an...
