Abstract

The invention relates to a large-span vibrating screen exciter for sludge water treatment, slurry treatment and material screening and conveying. The large-span vibrating screen exciter comprises a motor and a vibrating screen, wherein the motor adopts a shock-proof motor, the two ends of the shock-proof motor are connected with a universal transmission shaft through a coupling, the universal transmission shaft is connected with at least two eccentric mass blocks through the coupling, and the eccentric mass blocks are supported on a motor base through a bearing and a bearing support; and the entire exciter is connected to be a whole through an extension cylinder component connected at the two ends of the casing of the shock proof motor. The shock-proof motor can be a flame-proof or non-flame-proof shock-proof motor. The invention effectively realizes the improvement on the force-mass ratio and the large span of the excitation system. The invention has the advantages of simple structure, convenient manufacturing and assembly, long service life and low cost. Compared with the prior special long-shaped large-span exciting motor, the cost performance of the invention is improved greatly, and the limitation that the prior long-shaped large-span exciting motor can not be enlarged further is broke through.

Description

technical field

[0001] The invention relates to an exciter, in particular to an exciter for a vibrating screen involving muddy water treatment, mud treatment, material screening and transportation, and belongs to the field of mechanical equipment. Background technique

[0002] At present, the hydraulic exciter used in industrial production is generally composed of a vibration cylinder, a hydraulic control reversing valve, an elastic element and a hydraulic system. The vibration cylinder is a double-rod differential cylinder. coupling. This hydraulic component uses a hydraulic system to ensure the stability of the frequency of the vibration system and to make it easy to adjust (see the first issue of "Heavy Machinery" in 1994, page 51 and the magazine "China Mechanical Engineering" in issue 8, 1999, page 866 .). On March 15, 2006, the Chinese Patent Office disclosed a utility model patent (Patent No.: 200520029824.8) named "Motor Exciter", which includes a casing, a stator ...
