Problems solved by technology

This solution still has the following problems: first, multiple foam filters are spliced, and the upper and lower supports of the filter are in point contact, which may easily cause the filter to break and fail; second: the disc filter device is a ceramic device, due to its relatively complicated structure , the production cost is high, resulting in high filtration cost and casting manufacturers can not afford and do not use

Embodiment Construction

[0025] Such as figure 1 with 2 As shown, the main body of the filter device is a ceramic shell 1, which forms a cavity, the cavity includes a diversion part 1-2, a confluence part 1-7 and a C-shaped sprue in the middle, wherein the confluence part 1-2 is located in the upper part of the shell, and the upper end is the inlet of the filter device; the diversion part 1-7 is located in the lower part of the shell, and the lower end is the outlet of the filter device; the C-shaped sprues in the middle are connected in parallel, each connected between the diversion part and the confluence part Between, a filter 2 is set in each C-shaped runner. In the present invention, the diversion part 1-2 is equivalent to the main pipe, and the multiple C-shaped runners are equivalent to branch pipes, and each branch pipe divides and filters the molten metal from the main pipe, and then gathers it to the confluence part 1-7.

[0026] In this preferred embodiment, as shown in the figure, the C-...

Abstract

The invention relates to a ceramic shell filtering device. A ceramic shell (1) forms a cavity; the cavity comprises a shunt part (1-2) positioned at the upper part of the shell, a converging part (1-7) positioned at the lower part of the shell, and C-shaped pouring gates in the middle, wherein the upper end of the shunt part (1-2) is an inlet of the filtering device; the lower end of the converging part (1-7) is an outlet of the filtering device; the C-shaped pouring gates are connected in parallel, and are respectively communicated between the shunt part and the converging part; and each of the C-shaped pouring gates is provided with a filter (2). The ceramic shell filtering device realizes the overall filtration of high-flow molten metal outside a casting mold through the design of shunting, filtering and converging, and satisfies the overall filtering requirements of molten metal of a large cast steel piece and an ultra-large cast iron piece outside the casting mold.

Description

technical field [0001] The invention relates to a casting ceramic mold shell, in particular to a ceramic mold shell filter device integrating multiple pieces of ceramic filters. Background technique [0002] The purification of molten metal plays an important role in improving the mechanical properties of castings. Therefore, filtration technology is particularly important in the purification of molten metal. [0003] In the production of auto parts castings, ceramic filters are used to filter molten iron, and its penetration rate has reached 90%. However, the molten steel filtration technology is subject to factors such as excessive pouring temperature, selection of ceramic filter types, and complex pouring system design. Using zirconia foam ceramic filters to filter molten steel will result in high overall filtration costs and poor technical reliability. The popularization rate is about 1-3%, which restricts the popularization and application of molten steel filtration te...
