Two-stage drive complex high-frequency vibration sieve

Abstract

A two-stage drive complex high-frequency vibration sieve belongs to the technical field of high-frequency vibration sieves and is used for dewatering operations for fine materials such as coal slime, tailings and sand and gravel. The technical scheme is that the sieve is of a structure of dual bodies of an upper high-frequency sieve section and a lower high-frequency sieve section, wherein the upper high-frequency sieve section is mounted at a large positive angle with the feed end higher than the discharge end, the lower high-frequency sieve section is mounted at a small positive angle with the feed end almost parallel to the discharge end or at a negative angle with the feed end lower than the discharge end, the lower high-frequency sieve section is connected to the rear portion of the discharge end of the upper high-frequency sieve section through an elastic member, the upper high-frequency sieve section and the lower high-frequency sieve section are respectively mounted with an independent vibration device, and the upper high-frequency sieve section and the lower high-frequency sieve section are up to 4500mm in the width of the sieve surface and up to 6000mm in the total length of the sieve surface. The two-stage drive complex high-frequency vibration sieve has the advantages of being reliable in operation, large scale achievable, good in dewatering effect and low in energy consumption and the like, solves the long-term unsolved technical problems of high-frequency vibration sieves, facilitates the development of the high-frequency vibration sieves, and has significant economic benefits.

Description

Technical field [0001] The invention relates to a high-frequency vibrating dewatering screen used for dewatering fine-grained materials such as coal slime, tailings, sand and gravel, and belongs to the technical field of high-frequency vibrating screen equipment. Background technique [0002] At present, high-frequency vibrating screens have been widely used in the dehydration process of coarse slime dehydration, tailings dehydration, sand and gravel dehydration and other fine materials. The high-frequency vibrating screen has three types of structures: electromagnetic vibrating high-frequency screen, mechanical vibrating high-frequency screen and electromagnetic and mechanical composite vibrating high-frequency screen, each of which has advantages and disadvantages. The electromagnetic vibrating high-frequency screen has good reliability and can be large-scaled, but the moisture content on the screen is too high, and the dehydration effect is not good; the mechanical vibrating h...
