Description

Technical Field

[0001] The invention relates to the technical field of prebaked anode production and processing, and in particular to a prebaked anode processing and forming machine based on a vacuum environment. Background Art

[0002] The production process of prebaked anodes is mainly divided into three steps: calcination, molding and roasting. Among them, the molding process is a key link that determines the quality of prebaked anodes. In the traditional molding process, a heavy hammer is used to provide pressure to the lower mold box to mold the prebaked anodes. Due to the extrusion of the heavy hammer, the molding is completed to form the prebaked anode green blocks. The molding process determines the quality indicators of the prebaked anode green blocks, among which the volume density of the prebaked anode green blocks is a key indicator to measure the quality of the prebaked anode green blocks. Good volume density can increase the quality of the finished prebaked anodes.

[0003] In order to extract the gas in the paste more thoroughly and obtain prebaked anode green blocks with higher volume density, prebaked anode forming equipment manufacturers have designed and manufactured vacuum forming equipment. The current vacuum forming equipment designs the upper mold box and the lower mold box into a closed structure. The internal opening of the mold box is connected to the vacuum equipment. After the measuring car unloads the paste, the upper mold box falls to form a closed environment, and the vacuum pump starts to work. However, the position near the exhaust hole is prone to dry material due to the rapid flow of air. In addition, due to the good fluidity of the paste, the smoke near the inside is not easy to be extracted. The sealing parts of traditional vacuum forming equipment have to be opened and closed frequently, causing the sealing ring to become a consumable, shortening the maintenance cycle of the equipment and increasing the cost of consumables. Summary of the invention

[0004] In order to solve the problem of incomplete vacuuming during the production of prebaked anode green blocks and reduce the frequent startup of vacuum forming equipment, the present invention provides a prebaked anode processing and forming machine based on a vacuum environment.

The outlet valve is indirectly connected to the main cabin through the buffer cabin, and the internal valve is controlled to open and close by the internal valve cylinder. The buffer cabin is connected to and installed with a buffer air inlet valve.

[0017] The buffer cabin is used to move the measuring vehicle out of the vacuum cabin after the material is discharged without affecting the vacuum environment of the vacuum cabin, thereby improving the continuity of production and reducing the opening and closing of the vacuum environment.
