Embodiment 1

[0033] Such as figure 1 , figure 2 and image 3 As shown, the sorting combination equipment provided by the embodiment of the present invention includes: a pretreatment component 100, a photoelectric sorting component 200 and an air screening component 300, and the photoelectric sorting component 200 and the gas screening component 300 are respectively connected with the preprocessing component 100 connected;

[0034] The pretreatment assembly 100 includes a size-selectable sifter configured to sieve the sorted raw materials within a preset particle size range into N-type sifted raw materials, and the particle size of the N-type sifted raw materials is Radius ranges do not overlap;

[0035] The particle size optional sieve passes the first N-2 type of screening material into the photoelectric separation module 200, passes the N-1st type of screening material into the air screening assembly 300, and discharges the Nth type of screening material , wherein the maximum partic...

Embodiment 2

[0065] Such as figure 1 , figure 2 and image 3 As shown, the sorting process provided by the embodiment of the present invention includes the following steps: identifying the particle size range of the sorted raw material;

[0066] If it is determined that the particle size range is within the preset particle size range, the sorted raw materials are screened into N-type sieved raw materials, and the particle size ranges of the N-type sieved raw materials do not overlap;

[0067] Use the photoelectric sorting method to sort the N-2 type of screening raw materials before sorting, and use the air sieve sorting method to sort the N-1st type of screening raw materials into the air sieve sorting component, and discharge the Nth type of screening raw materials , wherein the maximum particle size within the particle size range corresponding to the Nth type of screening material is less than or equal to the minimum particle size within the corresponding particle size range of the N...

Abstract

The invention provides a sorting combination equipment and a sorting process, specifically a kind of full dry sorting combined equipment and sorting process for lump coal (photoelectric sorter) and fine coal (gas screen sorter), It relates to the field of sorting technology. The combined sorting equipment provided by the present invention includes: a pretreatment component, a photoelectric sorting component and an air screening component. It is configured to screen the sorting raw materials into N-type screening raw materials, and the particle size ranges of N-type screening raw materials do not overlap; the particle size optional screener passes the first N-2 screening raw materials into the photoelectric sorting component, The N-1 type of screening material is passed into the air screening assembly, and the N-th type of screening material is discharged. The photoelectric separation assembly includes N-1 parallel photoelectric separators, and each parallel photoelectric separator is used for Process sieved raw materials corresponding to the particle size range. It can improve the sorting accuracy of materials while increasing the processing capacity of materials per unit time.

Description

technical field [0001] The invention relates to the field of sorting technology, in particular to a sorting combination equipment and a sorting process. Background technique [0002] At present, the coal preparation process generally adopts wet separation, which is complex and requires water during the separation process, which is not suitable for water-shortage areas in Northwest China, and the cost of water treatment is relatively high. In addition, in the alpine region, the product coal that is separated by wet method is easy to freeze and difficult to transport, and low-rank coal is easy to produce mud during wet separation. Therefore, more and more coal preparation processes begin to use dry separation for separation. [0003] However, when using dry sorting, when it is necessary to increase the processing capacity per unit time, the processing capacity can only be increased by increasing the number of sets of the same sorting system. Contents of the invention [00...
