Device for fastening ultrasonic vibrating screen

Abstract

The invention discloses a device for fastening an ultrasonic vibrating screen. The device comprises a screen body. A feed port is formed in the top end of the screen body, the feed port is covered with a dust cover, screen plates are arranged in the screen body, and fastening device bodies are arranged between the screen plates and the screen body. Each fastening device body comprises a bolt and anut, and the bolts and the nuts are spirally connected, annular grooves are formed in the side walls of the thread ends of the bolts. A base is arranged at the lower end of the screen body, a vibrating motor is fixedly installed at the upper end of the base, the power output end of the vibrating motor is connected with eccentric wheels, and longitudinal damping springs are arranged at the upper ends and the lower ends of the eccentric wheels respectively. Through the arrangement of the screen body, the screen plates, the fastening device bodies, the vibrating motor, the eccentric wheels, thelongitudinal damping springs and transverse damping springs, the problems that a traditional vibrating screen is too high in vibrating amplitude, short in service life and high in production cost aresolved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic vibrating screen auxiliary equipment, in particular to an ultrasonic vibrating screen fastening device. Background technique [0002] Ultrasonic vibrating screen converts 220v, 50HZ or 110v, 60HZ electric energy into 38KHZ high-frequency electric energy, inputs it into an ultrasonic transducer, and turns it into 38KHZ mechanical vibration, so as to achieve the purpose of efficient screening and net cleaning. The modified system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the traditional vibrating screen and superimposes a high-frequency and low-amplitude ultrasonic vibrator on the screen, and the ultra-fine powder receives huge ultrasonic acceleration. , so that the material on the screen surface is always kept in a suspended state, thereby inhibiting the blocking factors such as adhesion, friction, flat drop, etc. [0003] However, in the actual p...
