Abstract

The invention discloses a feed grading screening device. The feed grading screening device comprises a cyclone separator, wherein a feed port connected with an outlet of an external granulator is formed in one end of the cyclone separator; a dust outlet connected with an external negative pressure pipe is formed in the other end of the cyclone separator; an air lock valve is arranged at the lowerend of the cyclone separator; an air lock shaft is arranged inside the air lock valve; an air lock motor for driving the air lock shaft to rotate is arranged outside the air lock valve; a plurality ofair lock blades are uniformly distributed on the air lock shaft; two of the air lock blades are always in close contact with the inner wall of the air lock valve during rotation; a screening box is communicated with the lower end of the air lock valve; a discharge port is formed in the lower end of the screening box. The feed grading screening device completes multi-stage separation of dust, scraps, a finished product and large-grain feed, so that the uniformity of the feed is guaranteed, the quality is improved, dust pollution is reduced and the surrounding environment is guaranteed; the dust, the scraps and the large-grain feed can be recycled, so that the cost is reduced.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a feed grading and screening device. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Pellet feed is a large category of feed. It is inevitable that there will be debris during the pelleting process. In order to ensure the uniformity of the feed, it is often sieved. The existing sieving devices generally only sieve the broken materials, and cannot sieve the feed fine powder and larger particle feed, which not only affects the uniformity of the feed, but also causes the feed fine powder to float in the surrounding environment. Affect the working environment, meanwhile, the waste of feed fine powder will also cause the increase of cost. Contents of the invention [0003] The technical problem to be solved by the pres...
