Description

Technical Field

[0001] This utility model relates to the field of powder processing technology in industrial production, and in particular to a fully automatic and efficient crucible unloading system. Background Technology

[0002] In current industrial production, it is common to fill powder into crucibles and continuously calcine it at high temperatures in a kiln to remove impurities. The crucibles, cylindrical containers made of refractory and heat-insulating materials, are arranged in a regular pattern on kiln cars and moved into the kiln for calcination via tracks. After calcination, the material is cooled by air and traditionally, it is manually fed into a silo by a vacuum feeder under negative pressure. In this process, manual operation can be adjusted according to the actual situation of the material to ensure the smooth progress of the feeding process, and the application of the vacuum feeder improves the feeding efficiency to a certain extent.

[0003] However, existing technologies have many problems in practical operation. First, the working environment temperature is high. Due to the poor thermal conductivity of the crucible and the limited effect of air cooling, the discharge temperature usually exceeds 250°C, resulting in high operating temperatures and increasing the labor intensity of workers. Second, material lumps easily clog the suction pipe. After calcination, the powder undergoes physical and chemical changes, shrinking in volume, sticking together, and agglomerating. Operators need to constantly crush and cut large material lumps to avoid blockage. Third, it is difficult to clean the material lumps stuck to the inner wall of the crucible, affecting the loading amount and thus production efficiency. Finally, the material at the bottom of the crucible is not completely sucked out, leaving a certain amount of powder residue, which affects output. Utility Model Content

Secondly, material lumps easily clog the suction pipe; after calcination, the powder undergoes physical and chemical changes, shrinking in volume, sticking together, and agglomerating, requiring operators to constantly crush and cut large lumps to avoid blockage. Thirdly, material lumps adhering to the inner wall of the crucible are difficult to clean, affecting the loading capacity and thus production efficiency. Finally, the bottom of the crucible is not completely cleaned, leaving a certain amount of powder residue, which affects output.

The material is pre-crushed by the crushing blade 45 inside the shield crushing head 42, while the steel wire rope flexible wall cleaner 46 cleans the material adhering to the inner wall of the crucible. The crushed and cleaned material is sucked in by the suction pipe 35 and transported through the pipeline to the heat exchange cooling tank 20 for cooling. After cooling, the material is filtered and separated by the filter bag 10 inside the vacuum feeder 2 and then enters the finished product silo 1. Finally, the material undergoes secondary crushing and weighing through the arch-breaking component 4, the slide valve 5, the first rotary discharge valve 6, and the pipe crusher 7 under the finished product silo 1, and is then loaded into the ton bag 9 for packaging. Throughout the process, the blower 3 provides the necessary airflow support to ensure smooth system operation.
