Flexible structure for vacuum-pumping system of vibratory forming machine

Abstract

The invention discloses a flexible structure for a vacuum-pumping system of a vibratory forming machine used in electrolytic aluminum production. The flexible structure is characterized in that one end of an inner pipe (1) is connected with a vacuum cover on a vibrating table; the other end of the inner pipe is connected with the bottom of a gasbag group (2) after passing through the inner cavityof the gasbag group (2); the whole body of the gasbag group (2) is arranged in an outer housing (3); the top of the gasbag group (2) is connected with the inner side of the top of the outer housing (3); a connecting pipe (4) is arranged on the outer housing (3); and the outer housing (3) is connected with the machine frame or base of the vibratory forming machine. The flexible structure is simple, has low manufacturing cost, and can satisfy the working condition requirement of the vacuum-pumping system of the vibratory forming machine, thereby solving the technical obstacle of retrofitting a vacuum-pumping system to a domestic vibratory forming machine and filling the gap of domestic technology in the link.

Description

Technical field [0001] The invention relates to a flexible structure of a vacuuming system of a vibration forming machine for electrolytic aluminum production. Background technique [0002] The quality of anode carbon block directly affects the current efficiency of electrolytic aluminum production and the quality of aluminum products. The anode carbon block formed by vibration in the vacuum state is better than the carbon block produced under normal pressure in terms of density and internal and external homogeneity, and the requirements for the paste temperature for producing the carbon block are looser. Since the forming of the carbon block is realized by violent vibration, a flexible connection must be set up between the fixed vacuum station and the vibrating mold sleeve to evacuate the forming space. This connection must be able to withstand the high temperature during forming. The frequency vibration can move with the mold sleeve in a larger range when the mold sleeve is op...

Problems solved by technology

However, the first problem with foreign products is: special materials, special production and small batch production, resulting in high prices, and domestic purchases are about 10,000 euros per piece; the second problem is that they are only provided as spare parts for their own vibration molding machine, there is no way for domestic molding machines to obtain this kind of product
