A partition is fixedly connected to the inner wall of the dust suction frame, and a cavity is formed between the partition and the inner wall of the dust suction frame. A number of through holes are evenly spaced on the partition, a filter screen is fixedly connected to the inner wall of the through hole, an air extraction pipe is fixedly connected to the outer wall of the dust suction frame, one end of the air extraction pipe is communicated with the cavity, and an air extraction pump is fixedly connected to the other end of the air extraction pipe".

The rotating mechanism 9 includes a groove gear ring 901, the groove gear ring 901 is fixedly sleeved on the bottom edge of the sieve plate 4, a connection opening 902 is opened on the screening cylinder 1 at the groove gear ring 901, a gear 903 is slidably connected inside the connection opening 902, a gearbox 904 is fixedly installed outside the screening cylinder 1, a clamping block 905 is fixedly installed at the output end of the gearbox 904, a telescopic sleeve 906 is arranged above the gearbox 904, the gear 903 is rotatably connected to the free end of the telescopic sleeve 906, and the gear 903 is clamped with the clamping block 905.

[0025] The vibration mechanism 8 includes a lifting cylinder 811, the lifting cylinder 811 is fixedly installed on the inner bottom wall of the screening cylinder 1, the rotating shaft 3 is located above the lifting cylinder 811, and a return spring 812 is fixedly installed at the top of the rotating shaft 3. Through such a setting, by the up and down movement of the lifting cylinder 811 and in cooperation with the return spring 812, the sieve plate 4 can be vibrated up and down.

[0026] A support sleeve 10 is fixedly installed inside the screening cylinder 1, and the rotating shaft 3 is rotatably connected inside the support sleeve 10. Through such a setting, the rotating shaft 3 can be limited.

[0027] The cross-sectional shape of the sieve plate 4 is a frustum shape, and positioning plates 11 are fixedly connected to both the upper and lower ends of the sieve plate 4 where the rotating shaft 3 is located. Through such a setting, it can be avoided that the screened glaze accumulates concentratedly in the middle.

[0028] The number of the discharge ports 5 is multiple, and the multiple discharge ports 5 are equidistantly distributed. Through such a setting, it is convenient for discharging materials.

[0029] The inner bottom wall of the collecting ring 7 is inclined, with the side of the inner bottom wall of the collecting ring 7 close to the outlet being the lowest and the side far from the outlet being the highest. Such a setting enables the discharged glaze to naturally slide down to the lowest point.

[0030] Based on the above structure,

[0031] Embodiment 2: The vibration mechanism 8 includes a motor 821, which is fixedly installed on the inner bottom wall of the screening cylinder 1. The sieve plate 4 is fixedly connected to the rotating shaft 3. A connecting plate 822 is fixedly installed at the output end of the motor 821, and a top rod 823 is fixedly installed on the upper surface of the connecting plate 822.

With such a setting, when the telescopic positioning column 826 expands and contacts the support plate 824, the top rod 823 cannot squeeze the extrusion block 825 to move in the vertical direction but drives the sieve plate 4 to move. When the telescopic positioning column 826 contracts to leave space for the up and down movement of the rotating shaft 3, the top rod 823 squeezes the extrusion block 825 to realize the vibration of the sieve plate 4. Through such a setting, the switching between driving vibration and driving rotation can be realized by using a single device.

[0032] Working principle: The glaze is placed into the interior of the screening cylinder 1 through the feed port 2, and multi-stage sorting is achieved by setting the multi-stage sieve plates 4 to vibrate up and down. During the vibration process, by setting the baffle 6 to cover the discharge port 5, it can be avoided that the glaze is discharged from the discharge port 5 before the grading is completed. After the vibration screening is completed, the sieve plate 4 is driven to rotate by the rotating mechanism 9. Under the action of centrifugal force, and when the baffle 6 does not completely cover the discharge port 5, the graded glaze is discharged from the discharge port 5, avoiding the mutual doping of the graded glaze in the prior art.
