The change in lead angle of the lobes may be continuous, i.e., portions of the lobes at different lead angles do not form a significant included angle. In addition, the lead angle can also be changed directly, i.e. the blade sections of different lead angles form a distinct angle.
The present invention provides an embodiment in which the lead angle of the helical integral blade is set to a first lead angle, a second lead angle, and a third lead angle, and the blades of the first lead angle, the second lead angle, and the third lead angle are sequentially arranged on the helical integral blade. And the first lead angle and the third lead angle are less than the second lead angle. The blades arranged at the first lead angle and the third lead angle are positioned at two ends of the spiral integral blade, and the blades arranged at the second lead angle are arranged in the middle of the spiral integral blade. Set up to first lead angle blade and be located the blade bottom, and the lead angle is less for just the material of entering device obtains inside the power access device of better upwards promotion, and less causes the blockking to the entering device material. The blade lead angle set as the second lead angle is larger, so that the material can rotate in the device faster under the pushing of the blade, the centrifugal force is improved, and the separation of the material and impurities is more thorough.

The sum of the proportion of the blades of the first lead angle and the blades of the third lead angle in the helical whole blade may be smaller than the proportion of the blades of the second lead angle in the helical whole blade.
The above solution is only one implementation manner of this embodiment, and this technical solution does not limit the number of changes in the lead angle of the blade, and the proportion of the blade at each lead angle to the whole blade, and can be adjusted according to actual conditions.
In an implementation manner of this embodiment, the screening component 3 may be divided into a first screening subcomponent and a second screening subcomponent … …, and an isolation net is installed inside each screening subcomponent, so that the present apparatus may form several independent compartments by each screening subcomponent and a corresponding portion of the rotating component 2, and may perform impurity separation processing on different kinds of materials at the same time without affecting each other.
In one implementation manner of this embodiment, the material of the screening member 3 may be a metal material, so as to ensure the mechanical strength and wear resistance of the screening member 3.
In one implementation manner of this embodiment, the material of the screening member 3 may be a plastic material, so as to reduce the weight of the screening member 3, and the screening member 3 is more convenient to disassemble.

It should be noted that the rotating member 2 performs better in a horizontally placed solution than in a vertically placed solution of the screen member 3. When the rotating component 2 and the screening component 3 are horizontally arranged, the materials in the device are driven by the rotating component 2 to rotate to generate the centrifugal force and the gravity, and when the materials rotate to the lower end of the device, impurities attached to the materials are separated from the materials through the screen holes under the action of the centrifugal force and the gravity; when rotary part 2 with screening part 3 is vertical to be placed, the material in the device not only receives rotary part 2 driven centrifugal force effect, moreover because material density is less for impurity such as earth, also continuously plays the separation effect under the gravity in rotatory in-process, makes the material is in rotatory in-process rotary part 2's upper portion, impurity such as earth sinks to rotary part 2's lower part or throws away from screening part 3 in rotatory in-process. Therefore, compared with the horizontal placement mode of the rotating component 2 and the screening component 3, the rotating component 2 and the screening component 3 are vertically placed and subjected to double sorting by centrifugal force and gravity, so that the separation effect of the materials and the impurities is better, and the time for separating the impurities is shorter.
