CERAMIC SHELL FILTER DEVICE INTEGRATED WITH MULTIPLE-PIECE FILTER

Abstract(summary):

Disclosed is a ceramic shell filter device. A ceramic shell (1) forms a cavity. The cavity comprises: a flow division part (1-2) which is located at the upper part of the shell, and an upper end thereof is a filter device inlet; a flow converging part (1-7) which is located at the lower part of the shell, and a lower end thereof is a filter device outlet; and C-type running channels which are located in the middle, wherein the C-type running channels are connected in parallel, the C-type running channels are in communication between the flow division part and the flow converging part respectively, and a filter (2) is arranged in each of the C-type running channels. By means of the design of flow division, filtration and flow convergence, the ceramic shell filter device achieves the overall filtration of molten metal at a high flow rate outside a casting mould, thereby satisfying the requirement of the overall filtration of molten metal for large steel casting and ultra-large iron casting outside a casting mould.
