Description

Technical Field

[0001] The utility model belongs to the technical field of material management devices, in particular to a visualized material feeding management device for a material bin of an aluminum electrolysis crane. Background Art

[0002] In the aluminum electrolysis production process, as the electrolysis process gradually proceeds, the content of electrolyte material components also changes. If the content of electrolyte material components changes too much, it will lead to an increase in the impurity content of aluminum products, reducing the quality and yield of aluminum products. Therefore, in order to keep the content of electrolyte material components in the electrolytic cell basically stable, it is necessary to add materials to the electrolytic cell in time. In the prior art, an overhead crane is usually used to add materials to the electrolytic cell. A silo is provided on the overhead crane, and a storage bin is provided in the workshop. A feeder is provided at the outlet of the storage bin. When the overhead crane moves close to the storage bin, the material is transported to the overhead crane silo through the feeder. When the overhead crane moves above the electrolytic cell, the silo is opened to add the material to the electrolytic cell. In order to increase the production capacity of the enterprise, an aluminum electrolysis production workshop often has multiple overhead cranes and multiple storage bins to improve the efficiency of adding materials. However, since the overhead crane is usually installed on the dome of the production workshop, the operator cannot observe the volume of materials in the silo, and the feeder cannot judge the volume of materials in the silo. If the feeder continuously transports materials to the overhead crane silo, the materials will overflow from the overhead crane silo, resulting in material waste.

[0003] In the prior art, a patent document with publication number "CN117568872A" discloses an aluminum electrolysis multifunctional overhead crane automatic feeding system and a control method thereof, the system comprising: a silo, a feeding valve is provided at the feeding port at the bottom of the silo; further comprising a control end, a trolley, a tool trolley, a first limit switch, a second limit switch, and a level meter, the tool trolley is provided with a material box, and the level meter is arranged in the material box; a knob switch is provided on the control end, when the knob switch is in the on state, the first limit switch and the second limit switch meet the trigger conditions in turn, and when the level meter signal is in an underfilled state, the control end can control the feeding valve to open. The feeding control method starts feeding when the set conditions are met and stops feeding when the material in the material box is full. The process of starting and stopping feeding is automatic. The patented technology basically realizes the automation of the feeding process. The above patented technology usually uses a detector with switching characteristics to detect the volume of materials in the silo. The corresponding detector only sends out two signals of "full silo" or "empty silo". When the overhead crane adds material to a certain electrolytic cell, if there is still material left in the overhead crane silo, and the feeder cannot identify the internal space condition of the silo, it will still cause the material to overflow the silo, which not only wastes materials but also affects the hygiene of the production workshop.

Compared with the prior art, the feeder can timely and correctly identify the material volume status in the silo. Even if there is still material left in the overhead crane silo, it will not cause the material to overflow the silo, which not only saves materials but also improves the sanitary environment of the production workshop.
