Description

Technical Field

[0001] The utility model relates to the technical field of coarse coal slime separation, in particular to a coarse coal slime water medium separation cyclone. Background Art

[0002] Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. Its properties vary greatly according to different varieties and formation mechanisms, and its availability also varies greatly. It has many types and a wide range of uses. Coarse coal slime refers to the coarse coal slime produced in the coal preparation process. Its particles are coarse, mainly including crushed coarse coal slime, secondary coarse coal slime and primary coarse coal slime. It is of great significance to improve the utilization rate of coal resources, reduce the labor intensity of workers and achieve sustainable development. When sorting coarse coal slime, a mud-water medium cyclone is needed.

[0003] The common coarse coal slime water medium separation cyclone is mainly composed of a feed port, a tangential feed port, a cylindrical section, an overflow pipe, a conical section and an underflow port. The material is introduced into the cyclone, and the tangential feed port introduces the material into the cylindrical section tangentially at a certain pressure. The cylindrical section centrifuges the material, and the overflow pipe collects the light material. The conical section further separates the heavy and light materials, and the underflow port is used to discharge the heavy material. This is the common structure and use of the coarse coal slime water medium separation cyclone. The traditional coarse coal slime water medium separation cyclone is not convenient for adjusting the separation density of the water medium separation cyclone, and it is impossible to achieve the density separation operation of the material without adding heavy medium. For example, patent number CN206701521U discloses a composite cone water medium cyclone with an adjustable overflow pipe. The insertion depth of the overflow pipe can be adjusted by a spiral hand wheel, a screw and a bracket to adjust the depth of the overflow pipe inserted into the feed barrel, thereby realizing the adjustment of the separation density in the water medium cyclone. The material can be separated by density without adding a heavy medium. However, in this method, since the fluid inside the cyclone is in a high-speed rotating state when the cyclone is working, the whole vibrates, and the spiral hand wheel and the screw are connected by threads. Under long-term vibration, they will become loose, resulting in the inability to control the depth of the overflow pipe inserted into the feed barrel. For this reason, a coarse coal slime water medium separation cyclone is proposed. Utility Model Content

When the overflow box drives the positioning rods to descend, the depth of the overflow pipe inserted into the outer shell can be determined according to the positioning rod scale lines on the positioning side plates, so as to avoid the overflow pipe insertion depth being too short or too long.

[0012] Preferably, a telescopic rod is vertically installed at the center of the back of the drive motor, and a fixing plate is added at the center of the rear end of the telescopic rod.
