Selective filtering precleaner

Abstract

The invention relates to a selective filtering precleaner, and belongs to the field of feed processing.The selective filtering precleaner comprises a machine body, a screen drum is rotationally connected into the machine body, a feeding pipe is arranged on the machine body, a discharging hopper is arranged at the bottom of the machine body, the feeding pipe is communicated with a precleaner pipeline and a receding pipeline, and the receding pipeline is communicated with the interior of the screen drum; the receding pipeline is communicated with the discharging hopper, a reversing mechanism is arranged on the feeding pipe and located between the precleaner pipeline and the receding pipeline, and the reversing mechanism is used for communicating the feeding pipe with the precleaner pipeline or communicating the feeding pipe with the receding pipeline. According to different conditions of the materials, the materials selectively enter the screen drum for preliminary cleaning or directly enter the discharging hopper for subsequent machining procedures, and the effect that the equipment abrasion degree caused by unnecessary use of a preliminary cleaning screen is reduced is achieved.

Description

technical field [0001] The present application relates to the field of feed processing equipment, in particular to a selective filtration primary cleaning sieve. Background technique [0002] Feed is a general term for food for animals raised by humans. The raw materials of feed include soybeans, corn, fish meal, additives, etc. In the production and processing of feed, the initial cleaning sieve is the equipment used for preliminary filtration of feed raw materials, and the cylinder initial cleaning sieve is one of the commonly used types of initial cleaning sieve. [0003] There is a sieve cylinder inside the cylinder primary cleaning screen, and a large number of sieve holes are opened on the sieve cylinder. The material enters the sieve cylinder, and the sieve cylinder rolls to separate the impurities from the material. The material whose size is smaller than the sieve hole is separated out of the sieve cylinder. Impurities whose size is larger than the sieve hole will ...

AI Technical Summary

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there are the following defects: if the raw materials have been preliminarily filtered and removed before entering the assembly line, the first processing procedure after entering the assembly line will hardly produce obvious effect, and increase the degree of wear inside the primary cleaning screen
