DETAILED DESCRIPTION

[0017] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-5 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0018] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0019] Embodiment 1, a ceramic powder screening device for preparing an anodic anti-oxidation coating, comprising a screening drum 1, wherein an array of screens 2 is arranged inside the screening drum 1, wherein a rotating shaft 3 penetrating the screen 2 is arranged inside the screening drum 1, wherein the rotating shaft 3 is driven by a power device, wherein a first discharge pipe 4 corresponding to the screen 2 is arranged at intervals on the side wall of the drum, and a second discharge pipe 5 is arranged at the bottom, wherein the first discharge pipe 4 and the second discharge pipe 5 are both provided with a blocking component, wherein first airflow pipes 6 cooperating with the screen 2 are arranged at intervals on the rotating shaft 3, wherein the first airflow pipe 6 is provided with an array of first air outlet holes 7, wherein the rotating shaft 3 A second airflow duct 8 located at the bottom of the screening drum 1 is provided on the shaft 3, and an array of second air outlet holes 9 is provided on the second airflow duct 8. A feed duct 14 is provided on the top of the screening drum 1; the blocking assembly includes a telescopic plate 10 provided on the first discharge duct 4, and also includes a plug 11 provided on the second discharge duct 5; the power device includes an electric motor 12 provided at the bottom of the screening drum 1, and the rotating shaft 3 is driven by the electric motor 12, and the electric motor 12 is electrically connected to the controller; the side wall material of the screening drum 1 is made of transparent material; four groups of shock-absorbing bases 13 are provided at the bottom of the screening drum 1.

[0020] When in use, after the feed pipe 14 provided at the upper end of the screening drum 1 is connected to the material conveying end, the material falls onto the uppermost screen 2 of the screening drum 1. The number of layers of the screen 2 can be set according to the process requirements, and the mesh numbers of the screen 2 can be set from large to small from top to bottom. At the same time, the motor 12 and the air pump are driven to work. The action of the motor 12 can drive the rotating shaft 3 to rotate, so that the first air flow duct 6 moves circumferentially along the screening drum 1. The air of the air pump is discharged from the first air outlet 7 to blow up the material. Since the mesh numbers of each layer of the screen 2 are different, the material can be divided into particles of different sizes to achieve the purpose of multi-stage screening.
