Coal bunker wall vibrating device

Abstract

The invention relates to a coal bunker wall vibrating device which is characterized in that a fixing base plate (10) is welded on the inner wall of a bunker wall (12), holes are correspondingly formed on the fixing base plate (10) and the bunker wall (12), a middle sleeve (11) is placed in the holes, a vibration connecting rod (7) is placed in the middle sleeve (11), one end of the vibration connecting rod (7) is provided with a vibrating plate (8), the vibrating plate (8) is fixed on the vibration connecting rod (7) by nuts (9), a vibration motor (1) and a vibration motor base (2) are connected with the other end of the vibration connecting rod (7) by fixed pins (3), a puller spring (6) is arranged outside of the vibration connecting rod (7), the puller spring (6) is fixed by puller nuts (4) and a spring collar (5), and the puller spring (6) is used for amplifying vibration amplitude of the vibration motor (1), so that the vibrating plate (8) in the bunker vibrates in a reciprocating way. The device provided by the invention has simple structure and can be transformed, installed and regulated conveniently; and compared with the prior art, the device has substantial characteristics and progress, can effectively solve the problems of material binding and material blockage in the bunker, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of an auxiliary device in the coal blending production process in the coking industry, in particular to a coal bunker wall vibration device. Background technique [0002] In the process of coal blending production in the coking industry, each single type of coal and blended coal must be pre-stored in the coal bunker before entering the next process. Due to the influence of coal powder humidity, viscosity, particle size, etc., it is easy to form fluff, The sticky material makes it difficult to lower the coal, and the coal material must be pulverized by vibration, so that the coal lowering can be carried out smoothly. In the prior art, the known vibrator, one is a silo wall vibrator installed on the outer wall of the silo, through high-frequency vibration, the power is transmitted to the silo wall to make it resonate, and at high frequency Under the action of vibration, the material and the bonding layer of t...

AI Technical Summary

Problems solved by technology

These two vibrators have the following defects: the silo wall vibrator on the outer silo wall of the silo transmits power to the silo wall, and the resonance is greatly affected by the thickness of the silo wall. If the silo wall is thick, the resonance amplitude is small, and the force on the material layer is small.

The effect is not ideal; the built-in vibrator has a small area of ​​action
