Abstract
The utility model discloses a ring-shaped spiral discharging device for an annular roller type vertical mill. A large belt wheel is mounted at the lower end of a spindle; a spoke of the large belt wheel is a lower spiral spoke; a discharging hopper is mounted at the lower end of a shell; a material receiving hopper is arranged on the upper lateral face of the outer edge of an inner ring of the large belt wheel; and the material receiving hopper is sleeved on the outer lateral face of the lower end of the discharging hopper. The ring-shaped spiral discharging device provided by the utility model has the following technical effects that the material receiving hopper and the large belt wheel on the spindle of the annular roller type vertical mill are connected; and the spoke of the large belt wheel uses a spiral structure comprising a plurality of spiral blades. The spiral structure is in a descending spiral structure, and is communicated up and down, so that the spiral structure rotates with the large belt wheel; a conical material receiving opening is mounted at the upper part of a spiral center plate of the large belt wheel; the upper part of the spiral center plate of the large belt wheel is in butt joint with the material receiving hopper; when the large belt wheel rotates, a falling material is driven to fall down from a core part of the large belt wheel along a spiral face; and when the material is bonded, the material is discharged by using a spiral force, so that the defects in the prior art that the material is unsmooth to discharge and is easy to block can be eliminated.
Description
Technical field
The utility model relates to a kind of ring stone roller type vertical grinder drawing mechanism.
Background technology
Existing float mill, planetary vertical mill, wind are swept the drawing mechanism that annular grinder, pendulum roller mill, centrifugal circular mill etc. encircle stone roller type grinding machines, all are through from the charging of machine top, and material circumferentially falls from the cylindrical shell bottom, discharges from the machine side surface discharge bucket again.The side discharge bucket is a trapezoidal oblique slide structure; the upper end bore is large; the discharging opening bore is minimum; material is by falling along the circumferential straight line of cylindrical shell; close up gradually discharge along ladder chute; when material moisture greater than 10% the time; worn into the material of subparticle can be at passage turning, whereabouts and the discharge exit be the paste bonding and pile up; hindered the speed of material stream; cause discharge not smooth; even the obstruction discharge gate, cause shutdown, this also be existing flour mill material moisture can not continuous operation in greater than 10% situation one of reason.
The utility model content
The purpose of this utility model provides a kind of ring stone roller type vertical grinder circular spiral drawing mechanism, and this device can solve lower discharge port susceptible to plugging defective when material moisture is excessive effectively.
The technical solution of the utility model is, a kind of ring stone roller type vertical grinder circular spiral drawing mechanism is equipped with big belt pulley in the lower end of main shaft, and the spoke of big belt pulley is lower spiral spoke; Hopper is equipped with in lower end at casing, and ring outer rim upper side has receiving hopper in big belt pulley, and receiving hopper is enclosed within hopper lower end lateral surface.
The utlity model has following technique effect, receiving hopper is made the disjunctor shape with the big belt pulley on the ring stone roller type vertical grinder main shaft, at many helicoidal structures as propeller blade of width of cloth strip adoption of big belt pulley.This spiral is the decline spiral, be communicated with up and down, rotate with big belt pulley, a conical material receiving port is equipped with on the top of big belt pulley spiral former, docks with receiving hopper, when big belt pulley rotates, drive the core of falling material along helicoid from big belt pulley and fall, when materials from bonding, rely on spiral power to discharge, it is not smooth to have eliminated in the prior art discharge, the defective that easily results in blockage.
