Problems solved by technology

In this method, the transport vehicle logistics is long, the uniformity of the mixture is poor, and the automation of the conveying system is low. At the same time, the ratio of alumina and electrolyte cannot be accurately and real-time controlled, which is not conducive to the precise control of the insulation performance of the electrolytic cell covering material.

Embodiment 1

[0022] like figure 1 As shown, the system mainly includes: electrolyte transport vehicle 1, high-level electrolyte warehouse 5, high-level alumina warehouse 6, electrolyte conveyor 4, lifting equipment 2, pneumatic chute 9, fan, mixing and feeding device 3, control valve, Control system (not shown in the figure).

[0023] In this embodiment, a delivery system needs to build a high-level electrolyte warehouse 5 and a high-level alumina warehouse 6. Both the high-level electrolyte warehouse 5 and the high-level alumina warehouse 6 are built next to the corridor between the two workshops of the electrolysis workshop. And electrolyte transport distance is short.

[0024] The electrolyte transport vehicle 1 transports the crushed electrolyte powder to the high-level electrolyte bin 5 of the electrolysis workshop, and transports the electrolyte powder to the high-level electrolyte bin 5 through the lifting device 2, and the lifting device 2 selects bucket lifting according to the t...

Embodiment 2

[0029] like figure 2 As shown, the system mainly includes: electrolyte transport vehicle 1, high-level electrolyte warehouse 5, electrolyte conveyor 4, pneumatic chute 9, fan, mixing and feeding device 3, control valve, and control system (not shown in the figure).

[0030] In this embodiment, a set of conveying system only needs to build a new high-level electrolyte warehouse 5. The high-level electrolyte warehouse 5 is built next to the corridor between the two workshops in the electrolysis workshop, and the alumina can be obtained from the fresh alumina warehouse between the two workshops. To obtain, no need to build a new high-level alumina warehouse 6. Alumina enters the pneumatic chute 9 through the chute under the wall of the fresh alumina large storehouse. Electrolyte delivery and mixing methods are consistent with Example 1. Compared with Embodiment 1, this implementation can save the construction investment of the high-level alumina warehouse and reduce the consum...

Abstract

The invention discloses a novel aluminum oxide and electrolyte automatic proportioning covering material storage and transportation system. The system comprises a high-position electrolyte bin and a high-position aluminum oxide bin; lifting equipment is used for conveying electrolyte powder into the high-position electrolyte bin for storage; a concentrated phase conveying system is used for conveying aluminum oxide into the high-position aluminum oxide bin for storage; a electrolyte conveyor is used for conveying the electrolyte powder in the high-position electrolyte bin to a mixing and feeding device; a pneumatic chute is used for conveying the aluminum oxide to the mixing and feeding device; the mixing and feeding device is connected with a discharge port of the electrolyte conveyor and a discharge port of the pneumatic chute to realize mixing, and is discontinuously connected with a feed port of a crown block feed box to realize feeding. According to the heat preservation requirements of different production stages of an electrolytic cell, the conveying amount of the electrolyte powder and the aluminum oxide powder can be adjusted by adjusting a control valve and a novel mixing and feeding three-way control system, and automatic proportioning of the aluminum oxide and electrolyte in covering materials used on the electrolytic cell can be achieved.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to a storage and transportation system for a novel aluminum oxide and electrolyte automatic ratio covering material suitable for 200kA-600kA electrolysis series. Background technique [0002] With the gradual enlargement of the aluminum electrolytic cell, the heat balance of the electrolytic cell occupies a very important position in the aluminum electrolytic production process. In the electrolytic production process of aluminum electrolysis, due to the large heat energy consumption of the electrolytic cell, it is necessary to heat the upper surface of the anode group in the electrolytic cell by covering the upper surface of the electrolytic cell to properly reduce the heat dissipation of the upper part of the anode electrolytic cell, thereby reducing the heat of the electrolytic cell loss, to meet the energy balance of the electrolyzer. [0003] The cover...
