Description

Technical Field

[0001] The utility model relates to the technical field of removing impurities, in particular to a feed impurity removing device. Background Art

[0002] Feed is generally animal food processed from soybean meal, corn, meat and bone meal, grains and other main raw materials. Some of the raw materials of feed come directly from the fields, and inevitably contain impurities such as soil, sand, branches and leaves. The finished feed is not allowed to have impurities. During the feed production process, the impurities in the feed need to be strictly removed. Common impurities in feed include sand, small stones, plastics, metal objects, glass shards, etc. The most harmful are small metal objects and glass shards in the feed. These impurities are mixed with feed. When feeding livestock, they may cause damage to the oral cavity and digestive tract of livestock, and even cause the death of livestock, resulting in economic losses; in addition, when metal objects, small stones, plastics and other impurities are mixed in the feed raw materials, if they are not removed in time, it will have an adverse effect on the subsequent production and processing equipment. For example, if a metal nail enters a high-speed mixer, it will cause the mixer shaft to get stuck or damaged, and sometimes even endanger the safety of the operator; in addition, rotten branches and leaves in the feed will breed bacteria and reduce the shelf life and product quality of the feed. In the prior art, feed cleaning equipment mainly relies on sieves and magnets to screen out and remove impurities. The main problem is that the fine metal in the feed is generally attracted by the attraction of electromagnets or permanent magnets. However, the impurities attracted by the electromagnets or permanent magnets are increasing. After a period of use, the machine needs to be stopped for cleaning. Otherwise, more and more metal impurities may be attracted by the magnets, causing problems such as blocking the circulation of feed. Utility Model Content

[0003] In view of this, the utility model proposes a feed impurity removal device, which utilizes magnetic blocks to absorb metal impurities mixed in the feed. The metal impurities are separated from the feed as the drum rotates. When they rotate to the bottom of the drum, they lose magnetic force and automatically fall off, thereby achieving automatic removal of metal impurities and avoiding the problem of having to stop the machine for cleaning.
