In the process of ceramic production, ceramic pug is crushed by crushing equipment (such as ceramic pug crushing and granulating equipment) to obtain ceramic powder, and the particle size of the obtained ceramic powder is generally smaller than the sieve mesh of a sieve in the crushing equipment, so that large particles which cannot be used in the next process do not exist generally. However, these ceramic powders contain many small particles or fine powders having too small a particle size, and therefore it is necessary to remove this portion of unnecessary small particles to make the particle composition of the ceramic powder particles acceptable.
At present, the ceramic powder is generally screened by adopting a screening mode in the field of ceramic production, and the adopted equipment is a vibrating screen or a circular screen. These devices all employ a screen having a size of apertures. When the ceramic powder passes through the screen surface of the screen, small particles pass through the screen surface because the particle diameter of the small particles is smaller than the aperture of the screen, thereby achieving the purpose of separating the small particles of the ceramic powder.
However, since the water content of the ceramic powder is generally 5% to 10%, when the ceramic powder passes through the screen, a part of the ceramic powder is adhered to the periphery of the screen holes, which causes the screen holes to become smaller, even blocks the screen holes, and thus the screening device equipped with the screen has the following problems:

The pulse-jet ash removal device 34 is a common component of a dust collector and will not be described in detail in this specification.
In order to make the powder material more uniformly blown by the wind from the wind blowing port 22 during the falling, in the present embodiment, the feed port 21 is formed in a long shape and is provided above the left side of the sorting chamber 2 in the front-rear direction of the sorting chamber 2. The feed inlet 21 is arranged in a long strip shape to enable powder entering the sorting chamber 2 to fall in a waterfall shape. In the present embodiment, the number of the air blowing ports 22 is 3, the air blowing ports 22 are also long, the 3 air blowing ports 22 are uniformly provided on the left side of the sorting chamber 2 from top to bottom, and the air blowing ports 22 are substantially parallel to the feed ports 21. It should be noted that the number of the air blowing openings 22 may be increased or decreased according to actual needs. Theoretically, the larger the number of the air blowing openings 22, the more favorable the air blowing of the powder in the air separation chamber is, and the separation of the particles is facilitated. The 3 air blowing openings 22 are communicated with the air blower 7 through pipelines 6, each pipeline 6 connected with the air blowing openings 22 is provided with an air volume adjusting valve 61, and the air volume of each air blowing opening 22 can be adjusted through the air volume adjusting valve 61.
The lower part of the right side of the sorting chamber 2 is provided with 1 back flushing port 23, and the back flushing port 23 is arranged on the air guide column 200. As shown in fig. 4, the air guide column 200 is a straight quadrangular prism, the inside of the air guide column is hollow, the bottom surface of the air guide column is a right trapezoid, the side surface of the right-angle side of the right trapezoid is parallel to the bottom surface of the sorting chamber 2, and the side surface close to the left side surface of the sorting chamber 2 is provided with strip-shaped air holes.

The dust shielding plate 202 functions to prevent the ceramic powder from falling into the interior of the gas guiding column 200 through the blowback port 23.
The two bottom surfaces of the air guide column 200 are respectively communicated with the pipeline 6 of the air blowing port 22 positioned at the lowest edge through branch pipelines.
In the process that the ceramic powder particles fall to the lower part above the sorting chamber 2, under the action of horizontal right transverse airflow of the air outlet 22, the larger particles fall on the left side of the sorting chamber 2, the smaller particles fall on the right side of the sorting chamber, most of the powder floats in the sorting chamber and is finally sucked into the dust collecting chamber 3. However, since the ceramic powder contains about 10% of water, the small particles collected in the right part of the separation chamber 2, which should be sucked into the dust collecting chamber 3, are liable to adhere together to form "false" large particles, and finally fall out from the discharge port of the separation chamber 2. The effect that sets up blowback 23 is just solving this problem, and the "false" large granule that is located sorting chamber 2 right part is when falling soon, and under the impact of the different air currents of two strands of directions that blowback 23 and air outlet 22 blown out, a plurality of tiny granules that the adhesion is together can separate, and the floatage is in sorting chamber 2 right part once more, finally is inhaled in dust collecting chamber 3, reaches the purpose of separating out the less powder granule of particle size more thoroughly to ceramic powder.

The dust baffle 100 has two main functions, namely, the dust baffle serves as a partition of the sorting chamber 2 and the dust collecting chamber 3 to prevent powder from being directly brought into the dust collecting chamber 3 by airflow blown out from the air blowing port 22; secondly, the air flow of the air blowing port 22 is blocked, and the air flow is turned back to form a rotary air flow after being blocked by the dust blocking plate 100, so that the powder in the sorting chamber 2 can be stirred sufficiently.
A plurality of ash discharge hoppers 8 are arranged below the dust chamber 32, star-shaped ash discharge valves or spiral ash conveyors 9 are arranged at the bottoms of the ash discharge hoppers 8, and in the embodiment, the number of the ash discharge hoppers 8 is 3.
