Description

Technical Field

[0001] The utility model relates to the technical field of filter plates, in particular to a filter plate for an aluminum alloy casting flow trough. Background Art

[0002] During the casting process of aluminum alloys, the aluminum liquid in the casting launder is filtered through a filter sheet to separate solid inclusions suspended in the melt.

[0003] The prior art has a publication number of CN220880535U, and the technical solution disclosed in the patent document is as follows: a filter plate for aluminum alloy casting flow trough, which relates to the technical field of molds, and solves the problem that the corrosion resistance of traditional glass cloth used for aluminum alloy filtration deteriorates with increasing temperature and time. During the filtering process of molten aluminum, the aluminum silicate gasket seals the main board and the casting flow trough to prevent the molten aluminum from passing through the casting flow trough without being filtered by the filter plate.

[0004] The above patent filters by setting a main board in the flow channel. The filtering structure is simple. When the aluminum liquid passes through, it is filtered only through a single straight hole mesh. The filtering time is short, resulting in poor filtering effect of the aluminum liquid. In addition, when the aluminum liquid flowing in the flow channel rushes to the filter plate, the filter plate will be deformed due to the impact force, and the strength is low, which will cause damage to the filter plate and reduce the filtering effect.

The outer surface of the rubber ring is fixedly connected to a baffle in the circumferential direction, and the baffle is provided with liquid outlet holes arranged in an array.

[0018] As a further preferred embodiment of the present technical solution, the rubber ring is arranged on the front outer surface of the guide ring, and the baffle is in a fan shape.
