Sliding guide stock bin

Abstract

The invention relates to a sliding guide stock bin. The sliding guide stock bin is a part installed and constructed in a guide sliding frame of a crust breaking and discharging device of an aluminum electrolysis cell, the sliding guide stock bin can adjust the working height of a guide discharging pipe assembly under the driving of an upper portion driving device, and is characterized in that thesliding guide stock bin is of a groove-shaped structure formed by a connecting bottom plate, front and rear side plates and left and right side plates, a groove frame and the sliding guide frame of the groove-shaped structure are configured, a crust breaking hammer guide pipe penetrating hole and an aluminum oxide drainage hole are constructed in the connecting bottom plate, an aluminum oxide material collecting bin formed by separating through a baffle plate is constructed between the front side plate and the rear side plate and above the aluminum oxide discharge hole of the bottom connectingplate, and the height of the left side plate and the right side plate of the sliding guide stock bin is larger than that of the front side plate and the rear side plate, namely, the left side plate and the right side plate of the sliding guide stock bin are designed for heightened channel steel or heightened thick steel plates, so that the sliding guide stock bin has the function of a linear guide sliding rail.

Description

technical field [0001] The invention provides a slide-guiding silo, which is a component installed in the guide sliding frame of the shelling and unloading device of the aluminum electrolytic cell, and is mainly used in the structural design of the aluminum electrolytic cell, the manufacture of production technical equipment, and the production of the aluminum electrolytic cell. Background technique [0002] In order to solve the problem that the hammer head sticks to the electrolyte solution to form a long bag during the production process of the aluminum electrolytic cell, and the problem that the alumina powder cannot be directly added to the fire hole of the discharge port of the electrolytic cell after it leaks from the feed pipe, and the problem that the lower guide At the bottom of the feed port, the height cannot be adjusted. The applicant of this patent, Gao Dejin, applied for a patent titled "Aluminum Oxide Feeding Device for Aluminum Electrolyzer" in April 2017. T...

AI Technical Summary

Problems solved by technology

[0005] 1. Set the metal telescopic tube between the outlet of the constant volume feeder and the alumina guide pipe. Due to the difficulty in manufacturing, the height of the telescopic adjustment is small, and it is not easy to install, resulting in the flow of alumina from the outlet of the constant volume feeder. The powder cannot flow into the guiding and discharging pipe according to the set technical requirements.

Easy to cause disordered loss of alumina powder

[0006] 2. The rectangular plate-type guide slide plate set in the guide slide frame, due to the low height of the steel plate itself, the contact area and height of the slide guide on the inner wall of the guide slide frame are small, and the electrolytic cell is affected by the electromagnetic force of the magnetic field , easy to produce swing offset, resulting in large swing of the guide pipe of the shelling hammer head and the end of the discharge port, poor guiding performance, and easy to cause jamming

[0007] 3. After long-term operation, the sliding gap between the rectangular guide slide plate and the inner wall of the rectangular guide frame will increase with the wear of the dispersed alumina dust material, resulting in the leakage of alumina powder from the constant volume feeder. It will diffuse from the sliding gap, and make the flue gas in the electrolytic cell overflow and diffuse from this place, which is not conducive to environmental protection production.

[0008] 4. The outer structure of the guide sliding frame is relatively large, and a higher guide sliding frame needs to be constructed to meet the travel requirements of the up and down movement of the rectangular guide slide.
