Aquatic feed particle powder screening device

Abstract

The invention discloses an aquatic feed particle powder screening device which comprises a box body, a rotating shaft, a second screening plate, a dust collecting pipe and a cover plate. A feed inletis fixedly formed in the left side of the box body, baffle plates are arranged on the front and back sides of the upper end of a first screening plate, a fixed plate is mounted below a spring, the rotating shaft penetrates into the fixed plate, the second screening plate is located below the first screening plate, a collecting box is arranged below the second screening plate, a supporting seat isarranged below the collecting box, the dust collecting pipe is located at the upper end of the box body, a dust storage tank is mounted at the back end of a sucking pump, a dust collecting hood is mounted on the right side of the sucking pump, the cover plate is located at the lower end of the dust collecting hood, and a conveyor belt is mounted at the lower end of the cover plate. The aquatic feed particle powder screening device can screen particles and detritus of an aquatic feed uniformly, and can collect the dust, so that the powder is collected more cleanly.

Description

technical field [0001] The invention relates to the technical field of aquatic feed production, in particular to an aquatic feed granular powder screening device. Background technique [0002] In the process of processing aquatic feed, a granulator is needed to granulate. When granulating, the prepared mixture is compacted and extruded from the die hole to form a granular feed, and then packaged. However, during the granulation process of the granulator, Still can be mixed with a part of powdered feed that does not form granular feed, and this part of powdered feed affects the quality of the product. At the same time, when feeding in aquaculture, powdered feed is easy to cause waste and pollute water quality. [0003] At present, there are many devices for producing and processing aquatic feed on the market, but most of them still have many deficiencies. For example, the existing screening devices cannot screen the granular powder of aquatic feed very well, and cannot renew ...
