Energy saving vibrating screen

Abstract

The invention relates to an energy-saving vibration sieve, which comprises a sieve body, a support device and a vibration exciter, wherein the support device is used for supporting the sieve body, the vibration exciter is used for driving the sieve body to move relative to the support device, the sieve body is assembled on the support device along the horizontal direction in a guide moving way, the vibration exciter is provided with a vibration exciter output end used for outputting the horizontal displacement, an elastic device is arranged between the vibration exciter output end and the sieve body, in addition, the vibration exciter output end and the sieve body are in transmission connection through the elastic device, and the elastic device has the deformation direction consistent to the guide moving direction of the sieve body. During the work process, the vibration exciter moves in the horizontal direction, the sieve body and materials do not need to generate vertical movement through driving, and the working by overcoming the gravity is not needed. In addition, the elastic device realizes the buffer effect during the starting, the acting force requirements during the starting can be reduced, the energy can be stored in the operation, and the energy loss when the sieve body moves to the maximum stroke can be reduced, so the integral energy utilization rate is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to an energy-saving vibrating screen. Background technique [0002] Vibrating screen is a commonly used screening equipment for granular materials, widely used in civil engineering, chemical industry, mining, medicine, food and other industries. According to the running track of the material during operation, the existing vibrating screens can be divided into linear vibrating screens, circular vibrating screens and fine vibrating screens. The existing vibrating screen is mainly composed of a screen body, a support device, and a vibrator for driving the screen body to move relative to the support device. Drive the screen box for reciprocating motion. For example, the application number is 201410236182.2, and the Chinese patent application publication number is CN103977951A discloses a mining linear vibrating screen, which includes a pillar as a supporting device and a screen body arranged on the pillar. There is a vibrating devi...

AI Technical Summary

Problems solved by technology

However, when the existing vibrating screen is working, since the exciter needs to drive the screen body and the material to produce vertical motion together to do work, the requirements for the self-weight of the screen body structure and the driving force of the vibrator are relatively high; moreover, the exciter When the vibrator is just started, it needs a large starting torque and a high-power drive motor. The cost of the motor is high, the impact on the power grid is large, the power factor is low during operation, the load loss transmitted by the generator to the screen is large, and the power consumption is large. , high energy consumption, low efficiency

In addition, the vibrating screen is prone to damage under the long-term vibration load of the exciter, especially the parts of the screen body, which require frequent maintenance and have a great impact on production efficiency
