Description
Technical Field
The utility model belongs to vibration screening machinery mainly relates to the spiral circular cone orbit screening machine that can carry out all-round screening to the material.
Background
In the existing screening machines, there are three general vibration trajectories of the screening machine: straight lines, circles, and ellipses. The three trajectories all occur in the longitudinal plane of the vibrating screen, so that the material particles only have a motion throwing force in the longitudinal plane and are not stressed in the transverse direction of the vibrating screen. Therefore, once the particles difficult to screen or irregular critical particles are clamped in the screen holes, the particles are difficult to find out a proper stress angle to pop up or fall off, and further, the holes are blocked, and the screening efficiency is influenced. In addition, the material layer is difficult to be uniformly loosened from thick to thin from the feeding end to the discharging end of the screening machine, the effective utilization area of the screen surface is low, and the screening efficiency is also influenced.
Chinese patent No. 200910208010.3 "a spiral orbit shale shaker", its sharp excitation source of shaking and the line of action of violently shaking the excitation source resultant force all pass through the barycenter of sieve case, and the orbit that forms is columniform spiral orbit, and the orbit size from feed end to discharge end is equal, and to the condition that feed end material layer is thick, the screening effect is not good, is unfavorable for the improvement of screening efficiency. The Chinese patent No. 201610198022.2 provides a vibrating screen with transverse force, and because the vibrating screen has no longitudinal acting force, the movement of materials must depend on the inclination angle of the screen surface, and the screening efficiency is limited. In addition, the screening machine is provided with the elastic rod connected with the spherical support at the discharge end, so that the amplitude of the discharge end of the screening machine is limited while a conical track is formed, and the screening efficiency is very low. The existing vibration sieve with the amplitude decreasing gradually is suitable for sieving the thickness of a material layer, and does not realize all-dimensional sieving and solve the problem of sieve penetration of irregular materials due to the absence of transverse acting force.
