Novel bottom-flow water-flow adjustable cyclone

TLDR: In this article, a bottom-flow water-flow adjustable cyclone was proposed to solve the problems of blockage of a bottom flow port as well as overflow and running of coarse particles of an ordinary hydraulic cyclone.

Abstract: The invention relates to a novel bottom-flow water-flow adjustable cyclone which can be used for solving the problems of blockage of a bottom flow port as well as overflow and running of coarse particles of an ordinary hydraulic cyclone. The novel bottom-flow water-flow adjustable cyclone is characterized in that a cone, bell mouth and conical cylinder cyclone taking a cylinder 2 as an upper body, taking a cone 4 as a middle section and arranging a bell mouth bottom-flow section 5 at the lower part is arranged, wherein a feed port 1 is arranged at the side end of the cylinder 2, an overflow pipe 3 is arranged at the center of the top end of the cylinder 2, a bottom-flow port adjustable device 6 is arranged in a bell mouth of the bottom-flow section 5, the bottom-flow port adjustable device 6 is arranged at the mouth of the cylinder, and the upper-body cylinder 2, the middle-section cone 4 and the lower-part bell mouth bottom-flow section 5 are sequentially hermetically connected through connecting discs arranged on respective edges and fixed through bolts 8. The novel bottom-flow water-flow adjustable cyclone has the advantages of improving the separation precision of coal particles, lowering a separation lower limit, playing a role in reverse regulation of pressure, improving the separation effect of the cyclone and being suitable for separation applications of coal and other minerals according to the density.
