Vibration screening mechanism and early warning device for vibrating screen mesh rupture

Abstract

The invention provides an early warning device (2) for vibrating screen mesh rupture in a vibration screening mechanism (1). The early warning device comprises a supporting part (21), a rotating arm part (22) and a sensor (231), wherein the supporting part (21) is fixed on a discharging conduit (13) of the vibration screening mechanism (1); the rotating arm part (22) is provided with a pivoting part which is pivoted with the supporting part (21), and a first end which is arranged in a flow path of screened materials; and the sensor (231) is arranged on the supporting part (21) or the rotatingarm part (22) and is used for sensing the pivoting position of the rotating arm part (22) and triggering an early warning signal. The early warning device realizes the early warning effect on the screen mesh rupture according to the flow rate of screened sand discharged from the discharging conduit, avoids inefficient work of a worker for checking the screen mesh every day, realizes real-time monitoring of the screening effect, can timely early warn when the screen mesh is failed, is convenient for the worker to timely repair and replace the screen mesh, and can more accurately control the proportioning of the mixed raw materials.

Description

technical field [0001] The present invention relates to a vibrating screening mechanism, more specifically, to a vibrating screening mechanism early warning device for breaking a vibrating screen mesh and a vibrating screening mechanism equipped with the early warning device. Background technique [0002] At present, in the process of using dry powder mixing plant equipment, it is necessary to meet the requirements of precise proportioning of raw materials, especially to ensure the precise proportioning of sand and gravel with different particle sizes. Therefore, a vibrating screening mechanism is provided in the dry powder mixing station equipment. [0003] Such as figure 1 As shown, the vibrating screening mechanism 1 in the prior art includes one or more vibrating screens 11 , a hoist 12 , one or more discharge conduits 13 and one or more silos 14 . Wherein, the vibrating screen 11 is located between the elevator 12 and the top of the feed bin 14, and is inclined; the d...

AI Technical Summary

Problems solved by technology

[0004] During the screening process, the friction between the screen and the sand and gravel is relatively large, and rupture often occurs, which is a loss part.

The shortcoming of above-mentioned vibratory screening mechanism 1 is: in the screening process, whether the screen is broken or not cannot be judged from the outside

This method of operation involves a lot of work, which increases the danger of workers' work, and it is impossible to know when the screen was broken, and the impact on the screening accuracy is also unknown.
