High-effective material charging vehicle

Abstract

A high-effective material charging vehicle. The invention belongs to the technical field of auxiliary devices for electrolytic aluminium production in an electrolysis workshop in an aluminum factory, and particularly relates to the high-effective material charging vehicle. The invention provides a high-effective material charging vehicle which is simple in structure and is accurate in quantitative material charging. The material charging vehicle includes a vehicle body. A material cabin is disposed on the vehicle body. A material discharge outlet on the bottom of the material cabin is connected to a material feeding device through a transition cabin. A quantitative apparatus is disposed in the transition cabin and includes a quantitative cylinder of which both the upper end and the lower end are opened. A connection rod is disposed in the quantitative cylinder. The upper end of the connection rod is connected to a driving apparatus on the material cabin. A lower plug, which is corresponding to the lower opening of the quantitative cylinder, is arranged on the lower end of the connection rod and an upper plug, which is corresponding to the upper opening of the quantitative cylinder, is arranged on the upper end of the connection rod. The distance between the lower plug and the upper plug is larger than the height of the quantitative cylinder.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for electrolytic aluminum production in an electrolytic workshop of an aluminum factory, and in particular relates to a high-efficiency feeding vehicle. Background technique [0002] When producing electrolytic aluminum in the electrolytic workshop of aluminum factory, a certain amount of fluoride salt is added to ensure the stability of acidic electrolyte components and improve the conductivity of electrolyte components. At present, there are two methods of feeding fluoride salt, manual and mechanical feeding. The main method of mechanical feeding is that the fluoride salt production workshop sends the fluoride salt to the silo, transports the fluoride salt to the transition bin through the dense phase, and then according to the electrolytic cell The fluoride salt is automatically replenished according to the material level of the silo, and finally the electrolytic cell is regularly a...

AI Technical Summary

Problems solved by technology

These two methods have great disadvantages: 1. The accuracy of the manual feeding method is not accurate, and the labor cost is still gradually increasing

[0003] 2. Although the mechanical feeding method realizes regular and quantitative addition of fluoride salt and mechanized production, it has relatively high requirements. This method requires: 1. The electrolysis workshop must have a dense phase conveying system

In this way, it is difficult to achieve very accurate feeding

[0009] At present, the feeding truck in the above-mentioned patent application documents has been used in some enterprises. Because it cannot achieve accurate feeding, some companies even set up a feeding bin specially used for quantitative feeding above the electrolytic cell; the feeding truck It is necessary to send the material to the feed bin with a higher height, and then the feed bin is used for quantitative feeding to the electrolytic cell

[0010] In addition, the separator used uses the form of interlaced movement of the isolation plates to realize the closing and opening of the feeding bin and the storage bin, and the interlaced movement of the isolation plates is prone to wear and tear, resulting in poor sealing, and if there are hard particles in the material If there is no solid material, the isolation plate will be stuck, resulting in the failure of the feeding port to close normally, and it is even more difficult to ensure the quantitative feeding of the electrolytic cell.

[0011] Third, the above-mentioned patent application documents are applied in relatively large aluminum plants, which have complex structures, large volumes, and high production costs, which are unacceptable for some small and medium-sized aluminum plants and have poor adaptability
