Abstract

The invention discloses a classifying screen with a pull belt type annular screening belt. Classification of material is an important link in industrial production, and a material classifying screen is large industrial equipment used for material classification. According to the scheme, the classifying screen with the pull belt type annular screening belt comprises an equipment rack (1) and a screen box (2) hung on the equipment rack, a head wheel (21) and a tail wheel (22) are hinged to the screen box through shafts and bearings, the head wheel is connected with a rotation driving device (23), the screen box is connected with a flat-return driving device (24), the annular screening belt (3) serves as a conveying belt to be arranged on the head wheel and the tail wheel in a sleeving mode,the annular screening belt comprises a set of pull belts (31) and a set of screen plates (4) mounted on the pull belts, the screen plates are sequentially arranged to form a screening face, screeningholes (41) are formed in the screen plates, a screen face lifting device (5) is arranged at the lower part of the annular screening belt and is fixedly connected with the screen box. The classifying screen is widely applied to industries such as grains, coal, metallurgy, mines, chemical engineering and environmental protection.

Description

technical field [0001] The invention relates to a material grading sieve in a physical mode, which realizes low energy consumption and high screening efficiency and effect through precise local vibration. Background technique [0002] Material grading is an important link in industrial production. Material grading sieve is a large-scale industrial equipment used for material grading. It is widely used in grain, coal, metallurgy, mining, chemical industry, environmental protection and other industries. The grading sieve in the grain industry is also called Cleaning sieve, its function is to sieve the large, medium and small impurities in the grain. The grading sieve in the coal industry is used to divide the coal into different grades according to the shape and size for different needs. In the higher education textbooks of different industries such as grain and coal, material classification theory is an important chapter. Sieving is an indispensable technical research direct...
