Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0017] The coarse coal slime separation system uses water as the medium to separate the coarse coal slime. In this embodiment, the mixture of coarse coal powder, gangue impurities and water is called slime water. The coarse coal slime includes coal with large particle diameter differences. Granules, gangue and other non-combustible substances are called ash. The coarse coal slime separation system can extract coal particles with a particle diameter within the required range from the slime water to form a concentrat...

The invention discloses a coarse slime sorting system and method. The coarse slime sorting system comprises a feeding mechanism, a coarse slime sorting machine, a concentrate discharging mechanism anda controller. The feeding mechanism comprises a feeding barrel, a feeding pump and a first grading cyclone; the feeding barrel is provided with a first liquid level meter; coal slime water in the feeding barrel is pumped into the first grading cyclone through a first switch gate valve by the feeding pump; a first valve limit switch monitors the in-place state of the first switch gate valve; the first grading cyclone is provided with a first pressure gauge; the controller can adjust the frequency of the feeding pump and the in-place state of the first switch gate valve according to first stable parameters including the liquid level of the feeding barrel, the frequency of the feeding pump and the pressure of the first grading cyclone, and so that the first stable parameters are within the standard range. The provided system and method can solve the problems that the sorting density of the sorting system is uneven and the sorting system is unstable.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a coarse coal slime sorting system and a sorting method. Background technique [0002] Telligent Coarse Slime Separator (TCS) is a slime separation system that uses water as the medium in coal preparation plants, and is an important process link in the production process of coal preparation plants for processing coarse slime. Through TCS sorting, it can effectively improve the product recovery rate of the coal preparation plant and improve the economic benefits of the coal preparation plant. [0003] However, in the prior art, in the coarse coal slime sorting process, the density of the sorting system with water as the medium is adjusted manually, and the continuous change of the partial flow rate makes it difficult to stabilize the pressure and flow of the slime, which is very difficult. It is difficult to achieve the stability of the sorting system. For example, in the feedin...
