AI Technical Summary

Technical Problem

When screening rapeseed using existing linear vibrating screens, the material tends to stay at the edges and corners, resulting in poor flowability and difficulty in screening out, thus affecting screening efficiency.

Method used

The vibrating screen structure adopts an inclined plate surrounding a sieve plate. The inclined plate is equipped with sieve holes and is combined with a limiting plate and an inclined screen. The collection structure is designed to collect impurities and control the flowability of materials. Through the cooperation of the inclined plate and the sieve holes, the flowability of rapeseed and the screening effect are enhanced.

Benefits of technology

It effectively filters out rapeseed from the edges and corners, improving screening efficiency, reducing the residence time of materials on the screen, and ensuring efficient separation of rapeseed and effective collection of impurities.

Abstract

The utility model relates to material screening technical field especially relates to a rapeseed screening device, include: screening chamber, vibrating screen, vibrating screen sets up in screening chamber, vibrating screen includes: inclined plate, sieve plate, sieve plate is surrounded by inclined plate, inclined plate is connected with the inner wall of screening chamber, inclined plate is inclined along the side close to the inner wall of screening chamber to the other side, and the sieve hole is opened to the side close to sieve plate of inclined plate. Some linear vibrating screen can leave larger impurities on the screen, and smaller rapeseed is screened down, but the structure of linear vibrating screen easily leads to some materials staying on the corner, and due to some impurities block, lead to these materials difficult to be screened down. Compared with prior art, the utility model uses the vibrating screen structure that inclined plate surrounds sieve plate, and the sieve hole is also opened on the inclined plate, so that the rapeseed at the corner can also be screened from the sieve hole, and at the same time, the rapeseed fluidity is greater, avoiding the problem that the rapeseed at the corner is difficult to be screened.
