A kind of feedstuff shakes and screens out powder system
Technical field
This utility model relates to Feed Manufacturing processing technique field, is specifically related to a kind of feedstuff gumming system, namely shakes and screen out powder system。
Background technology
Owing to sieve aperture is easily blocked or because of compass screen surface material skewness during pellet screening, cause that pellet fine powder material screening when screening is not thorough, so finished particle feedstuff packaging time finished product material pulverization rate content higher be about 2.5%, broken material and particulate material there is micropowder, classifying screen also is difficult to remove, the existence of these fine powders can affect the quality of feedstuff, also can increase the loss in packed and transported process, and the fine powder flown upward can have a strong impact on production environment, granule is even caused to suspend, the fire safety in workshop is constituted a latent danger, so, need pellet is carried out dedusting recycling。
At present, producing the powder assorted and less than finished particle greatly of conglomeration in Pelleting, a lot of Feed Enterprise are all with manually picking out these assorted greatly and powders and shifting aborning。Labor strength is very big, and efficiency is also very low。If assorted greatly and powder does not pick out in time because of anthropic factor will be mixed in finished particle, cause finished particle uneven and feedstuff rate containing powder exceeds standard, affect feeding quality。The dust shield that existing pellet powder separation retracting device is arranged is with traditional to arrange inlet scoop effect in feed bin upper end be the same, yet suffer from all being processed by the air of mixed-powders a large amount of in feed bin, some powder also do not siphon away and just deposited get off, the problem that gumming effect is bad。It addition, the sieve nest area of existing feedstuff bolter is little, material is high containing powder rate, is not easy to cleaning, and follow-up too long in flow material impacting pulverization rate is high。Therefore, how to research and develop to shake and screen out powder system, it is achieved the recovery of powder in feedstuff, have important practical significance。
