This utility model discloses a feed equalizer for poultry farming, belonging to the technical field of feed equalizers. The feed equalizer for poultry farming includes a feed equalizer box slidably installed in a feed trough, forming a feed accumulation area within the feed equalizer box. The inclined surface of the feed equalizer box and the feed trough form a feed recovery area. Fixed frames are fixedly installed at both ends of the feed equalizer box. It also includes: "L"-shaped guide plates symmetrically installed at both ends of the feed equalizer box, with the outer surface of the guide plates connected to the feed recovery area. Symmetrical interceptor plates are installed on the feed equalizer box, and these interceptor plates are installed within the feed recovery area. Rollers are rotatably installed on the feed equalizer box, and scraper plates are fixedly installed on the rollers. This utility model utilizes the scraper plate in conjunction with the interceptor plates to effectively scrape away some of the old feed located at the edge of the feed trough and collect it in the accumulation area to mix with the new feed. This prevents the old feed from becoming moldy or spoiled due to prolonged lack of consumption, thus avoiding problems such as affecting poultry health and increasing farming costs.

The invention relates to the technical field of blood filters, in particular to a two-channel graded targeted filtering blood filter and a using method.The two-channel graded targeted filtering blood filter comprises a targeted filtering bin, an anticoagulation bin is installed at the upper end of the targeted filtering bin through a second conveying pipeline, and the lower end of the targeted filtering bin is connected with a nutrition bin through a pipeline and a third electromagnetic valve; and an inner shell is installed in the targeted filtering bin, a fixing frame is installed in the inner shell, a first targeted pipe and a second targeted pipe are symmetrically installed in the fixing frame, and a second electromagnetic valve is installed at the upper end of the inner shell. A series of structures are arranged, a double-membrane double-channel filtration system is constructed through series connection design of the first targeting tube polyethersulfone small-aperture membrane and the second targeting tube polyethersulfone large-aperture membrane, small-molecular toxins and medium-macromolecular toxins are sequentially and accurately removed, the contact area is increased through the spiral tubular membrane structure, toxin residues are avoided, and the toxic and side effects are reduced. The blood filtration treatment effect is remarkably improved, and the requirements of patients with different toxin accumulation types are met.
