Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, and more specifically, to a device for screening impurities in early-stage feed raw materials. Background Art

[0002] Feed is the general term for food for animals raised by all people. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, grains, feed additives, etc. Generally, some impurities are mixed into the feed during the production process, which requires the use of filtering devices to screen the feed.

[0003] During the production process of existing feed, impurities are mixed in, so the feed needs to be placed in a screening device for screening. However, the traditional screening device cannot completely screen the feed and will waste a lot of time of the staff.

[0004] After searching, a Chinese patent with publication number CN213996746U discloses a feed and raw material impurity screening device. The structure puts the feed into the first screening chamber, and the feed and impurities are blown up by the rotation of the fan blade. At this time, the feed and impurities will be filtered through the filter plate, and the feed will remain in the first screening chamber. The impurities will enter the filter net through the filter plate. At this time, the filter net will filter the feed and impurities again, and the feed will fall to the bottom of the second screening chamber through the filter net. The device can screen the feed and impurities twice, so that the staff does not need to screen the impurities again, which saves the staff's time, is simple and convenient to operate, and improves the practicality and convenience of the device.

[0005] However, when this structure is actually used, the feed is directly put into the first screening cavity. When the feed is stored in the storage box, the feed is easy to clump in the box, resulting in the feed clumps in the first screening cavity being difficult to shake off, affecting the screening efficiency of the feed, thereby increasing the workload and delaying the work progress.
