提案が重ねられている。[Problems to be solved by the prior art and the invention When sieving powder and granules, conventionally, the sieve surface is kept on a plane close to the horizontal plane, and the powder and granules introduced from above are passed through reciprocating motion of the sieve surface. Alternatively, the sieve's ability to classify into fine powder that passes through the sieve surface and coarse powder that does not pass through the sieve surface is determined by vibration.
It has been expressed by the area of the sieve surface used. However, unless the sieve is constantly subjected to impact or repeatedly cleaned with a black or the like, it will quickly become clogged and become unusable. Therefore, many proposals have been made for efficient sieving of powder and granular materials.

別装置の出現が強く望まれていた。In particular, currently, pneumatic transportation accounts for the majority of methods for handling powder and granular materials, so as a proposal for pneumatic transportation,
Nie Air Screen (Classification Equipment Technical Handbook 5 Japan Primary Industry Association: p. 234. (1978)), Micro sifter (same book + p. 238. (1978)), Fine sifter (Powder equipment guide (1986 edition) , All Efficiency Association, Powder Industry Exhibition Secretariat, p. 90. (1986)
), but all of these have a sieve surface of a certain area to sieve the powder and granules transported with suction air,
As a means of eliminating clogging, we use a method of scanning and backwashing with high-speed air using a nozzle. Therefore, each device cannot be easily inserted into the middle of a powder air transport pipe, and is relatively large-scale. Furthermore, when scanning and backwashing the sieve surface, it takes a while after backwashing. Since the sieve surface that has passed through the sieve is subsequently contacted with powder and granules, it is likely to become clogged, and the sieving efficiency over the entire surface area must be reduced. There has been a strong desire for a simple sieving device that can sieve using a sieving surface and that can be easily installed in the middle of a powder air transport pipe.
