Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cyclone, concretely is a coal preparation cyclone. BACKGROUND

[0002] The coal cyclone is a device based on centrifugal force and fluid mechanics principle, and rotates viscous fluid to realize grading and separation of coal. When the mixture enters from the tangential direction of the periphery of the cyclone at a certain pressure, strong three-dimensional elliptical strong rotating shear turbulent flow motion is generated inside the cyclone. Due to the difference in density and particle size of different particles in the material, they are affected differently under the action of centrifugal force, centripetal buoyancy and fluid drag force. Through the rotating action of the cyclone, the coal can be effectively separated according to its density and particle size.

[0003] The utility model patent with patent application publication number 202323375501.1 discloses a coal preparation cyclone, relating to the technical field of cyclone, including cyclone body, inlet pipe, overflow pipe, underflow pipe, ball joint assembly and adjusting assembly, the side of the left end of cyclone body outer wall is equipped with feed inlet, inlet pipe is fixedly connected on cyclone body and is located inlet pipe outside; the overflow pipe is fixedly inserted in the left end of the cyclone body; the underflow pipe is fixedly connected at the right end of the cyclone body; the ball joint assembly is arranged at the port of the inlet pipe; the adjusting assembly is arranged at the left end of the outer wall of the cyclone body, and is used for adjusting the ball joint assembly. Through the mutual cooperation of the ball joint assembly and the adjusting assembly, the inclination of the material entering the inlet pipe port can be adjusted in the axial direction. The adjustment is convenient, so that the cyclone can adjust the angle of the material entering according to the actual needs, avoid the poor separation effect when sorting different materials, and improve the practicability of the device.

[0004] According to the above-mentioned patent, there is a coal preparation cyclone, which still has the following disadvantages in actual use: when the coal mixture contains a large amount of impurities or particulate matter, it will affect the separation effect of the cyclone, and even cause the cyclone to be blocked or damaged. At this time, the coal mixture usually needs to be filtered to remove large particles and impurities. However, when there are sticky impurities in the impurities, the vibrating filter plate is easily blocked, resulting in reduced filtering efficiency and affecting the working efficiency of the cyclone. Therefore, we propose a coal preparation cyclone. Utility model content
