Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a feed powder screening device. Background Art

[0002] Feed is a general term for food for all animals raised by humans. In a narrower sense, feed refers primarily to food for animals raised in agriculture or animal husbandry. Hard-grained feed, when subjected to friction from equipment and falling from high altitudes during the production process, can break into small dust particles and larger broken particles. If this unformed feed is not effectively cleaned, these impurities can easily enter the packaging during packaging, affecting product quality.

[0003] The existing reference announcement number is: CN208853260U Chinese utility model patent, which discloses a feed powder screening device, including a fine material screening mechanism and a powder screening mechanism, the fine material screening mechanism includes a sieve plate, a baffle fixed to one side of the sieve plate, and a flip assembly, a feeding channel is provided below the end of the sieve plate away from the baffle, a conveyor belt is provided below the feeding channel, and a powder absorption device is provided above the conveyor belt, a driving device pushes the hinge plate to tilt the sieve plate toward one side of the baffle, and the feed moves toward the baffle on the sieve plate, and fine materials with smaller particle sizes are screened out during the movement, and then the driving device pulls the hinge plate to tilt the sieve plate toward the side of the feeding channel, and transports the feed to the powder absorption device for secondary screening of dust in the feed. The device uses the flip assembly to make the feed move on the sieve plate to screen out the fine material, and then passes through the powder absorption device for secondary screening of the feed, and the two screenings respectively screen out fine materials and powder, and the screening is sufficient to ensure that the feed output from the device is of good quality, with less finely divided feed and powdered feed.

[0004] When screening, the existing screening device may get stuck in the metal mesh or grid, causing material blockage. At the same time, the existing screening device generally separates the material from the dust by vibration. In this way, the material will stay above the screening structure, affecting the screening efficiency and being very inconvenient during continuous operation. Utility Model Content
