Description

Spiral rotary screen

Technical Field

The utility model relates to the field of zirconia bead treatment, in particular to a spiral rotary screen.

Background

Zirconia beads (TZP zirconium beads for short) are prepared by using micron-scale and sub-nanometer-scale raw materials and adopting an advanced process, and various technical indexes and performances reach the international advanced level. The method is mainly applied to superfine grinding and dispersion of materials requiring zero pollution, high viscosity and high hardness, such as: electronic ceramics, magnetic materials, zirconia, silica, zirconium silicate, titanium dioxide, medical food, pigments, dyes, printing ink and special chemical industry.

The existing grinding method usually adopts a manual screening method, and the method can produce a large amount of waste beads every year, wherein about 75 percent of the 'grinding beads' can be used repeatedly, and a large amount of waste is generated because the 'grinding beads' cannot be separated by manpower (similar machines can replace the manpower in the market).

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

A spiral rotary screen as shown in fig. 1 or 2 comprises a frame 100 for supporting other components, a circular rotary filter mechanism 200 is disposed on the frame, a feeding port 201 of the rotary filter mechanism 200 is connected to a feeding hopper 300 through a feeding pipe 310, and replaced grinding beads are screened.

The annular rotary filtering mechanism 200 is internally provided with filtering screens with different grain diameters, specifically, a four-stage filtering screen structure, and the aperture ratio of the first to fourth-

stage filtering screens

210, 220, 230 and 240 is 0.85:1.15:1.35: 1.85. The aperture of the filter screen is increased along the reverse direction of the feeding port 201.

The corresponding collecting devices 400 are arranged at the lower parts of the filtering screens with different particle sizes to separately screen and collect materials with different particles.

Specifically, a first collection tub 410 for collecting the crushed materials is provided under the first filtering screen 210.

A second collection tub 420 for collecting the first type material is provided under the second filtering screen 220.

A third collection tub 430 for collecting the second grade material is disposed under the third filtering screen 230.

A fourth collection tub 440 for collecting a third type of material is disposed under the fourth filtering screen 240.

Different types of materials correspond to different grinding requirements. The width of the first filter screen 210 is greater than the width of any of the second through

fourth filter screens

220, 230, or 240.
