Problems solved by technology

And existing excitation motors, including the above two patents, are restricted by various factors due to the "force-to-mass ratio" between the excitation force and its own mass (i.e. the ratio of the excitation force to its own mass) , it is difficult to get further improvement, especially it is difficult to get a substantial imp

Embodiment 1

[0014] A large-span vibration exciter, including a vibrating screen and a motor, the motor adopts an anti-vibration motor 1, and the two ends of the anti-vibration motor 1 are connected with a universal joint transmission shaft 3 through a coupling 2, and the universal joint transmission shaft 3 is connected through a coupling The shaft device 2 is connected with two eccentric mass blocks 4, and the eccentric mass block 4 is supported on the motor base 7 of the side plate 8 of the screen box through the bearing 5 and the bearing seat 5; The elongated cylinder parts 9 connected at the ends are connected to form a whole. Wherein, the anti-vibration motor 1 is an explosion-proof anti-vibration motor. Since the anti-vibration motor used in this vibrator is not directly connected to the eccentric mass 4, the entire anti-vibration motor 1 is not directly affected by the radial centrifugal excitation force generated by the rotation of the eccentric mass 2. Therefore, the load on the...

Embodiment 2

[0016] The vibration motor 1 in the first embodiment is a non-flameproof and anti-vibration motor.

Embodiment 3

[0018] A large-span vibration exciter, including a vibrating screen and a motor, the motor adopts an anti-vibration motor 1, and the two ends of the anti-vibration motor 1 are connected with a universal joint transmission shaft 3 through a coupling 2, and the universal joint transmission shaft 3 is connected through a coupling The shaft device 2 is connected with two eccentric mass blocks 4, and the eccentric mass block 4 is supported on the motor base 7 of the side plate 8 of the screen box through the bearing 5 and the bearing seat 6; The elongated cylinder parts 9 connected at the ends are connected as a whole. Wherein, the anti-vibration motor 1 is an explosion-proof anti-vibration motor. The vibrator adopts frequency conversion to start, that is, starts at a low speed, and gradually reaches the rated operating speed for the stable operation of the vibrating screen, which can achieve the purpose of saving energy. The vibrating screen uses three exciters to vibrate at the ...

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 ...
