Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model provides a pair of fractional centrifuge, including casing 1 the equal welding bracing piece 1.1 of four corners in below of casing 1 passes through bolt fixed connection motor 1.2 in the below of casing 1, and motor 1.2's main shaft upwards passes the lateral wall of casing 1 welds rotary drum 2 on motor 1.2's main shaft, and rotary drum 2 sets up in the casing 1.

A first hydraulic cylinder 3 is fixed at the bottom in the rotary drum 2 through a bolt, the first hydraulic cylinder 3 is vertically arranged, a first piston plate 4 is welded on a piston rod of the first hydraulic cylinder 3,

an opening is formed in the upper portion of the shell 1, a cover plate 1.3 is hinged to the opening, and a second hydraulic cylinder 5 is fixed to the lower portion of the cover plate 1.3 through bolts. And a second piston plate 6 is welded on a piston rod of the second hydraulic cylinder 5, and the second piston plate 6 is arranged in the rotary drum 2.

A closed space can be formed between the first piston plate 4 and the second piston plate 6, so that materials can only rotate and be separated in the space, the aperture size of the filter holes in the rotary drum 2 is gradually reduced from top to bottom, and the materials can pass through different apertures by moving the first piston plate 4 and the second piston plate 6, so that particles with different sizes are separated.

The rotary drum type material separating device is characterized in that a group of annular plates 7 are welded on the inner wall of the shell 1 from top to bottom, in the embodiment, the number of the group of annular plates 7 is four, the rotary drum 2 is inserted at the inner ring of the annular plates 7, annular cavities 8 are formed between every two adjacent annular plates 7 and the rotary drum 2, three annular cavities 8 are shared in total, namely, the device can separate particles with three different apertures, when materials are separated, the second piston plate 6 is moved to be flush with the uppermost annular plate 7, the first piston plate 4 is moved to be flush with the second annular plate 7 above, the separated materials enter the first annular cavity 8, then the first piston plate 4 and the second piston plate 6 are moved according to the separating condition of the materials, and the separated materials enter the second annular cavity 8 or the third annular cavity 8.
