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 cavity of 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 vacuum pumping system of a vibration forming machine for electrolytic aluminum production. Background technique [0002] The quality of anode carbon blocks directly affects the current efficiency of electrolytic aluminum production and the quality of aluminum products. The anode carbon block formed by vibration under vacuum state is better than the carbon block produced under normal pressure environment in terms of density and internal and external homogeneity, and the temperature requirement for the paste used in the production of carbon block is relatively loose. Since the forming of carbon blocks is realized by violent vibration, a flexible connection must be provided between the fixed vacuum station and the vibrating mold sleeve in order to evacuate the forming space. This connection must not only withstand the high pressure during forming The vibration of the frequency can move with the mold slee...

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
