[0002] Fused ceramic sand, also known as pearl sand, has the advantages of high temperature resistance, no breakage, no dust, spherical shape, high air permeability, good filling, no silica dust hazards, etc. It is a green casting environmentally friendly sand. In the process of fused ceramic sand production, it is necessary to coarsely filter the formed fused ceramic sand according to the particle size, which requires the use of fused ceramic sand coarse filtration device.

[0003] In the related art, a filter screen (plate) is usually provided on the coarse filtration device of molten ceramic sand, and the filter holes on the filter screen (plate) are used to filter and screen the molten ceramic sand.

A plurality of filter holes 9 are evenly distributed on the bottom inner wall of the filter cartridge 8. The molten ceramic sand can be screened and filtered by using the plurality of filter holes 9, so that the required small particles of molten ceramic sand can be discharged through the filter holes 9 and fall, and the large particles of molten ceramic sand are intercepted inside the filter cartridge 8. An L-shaped plate 10 is fixedly installed at the bottom of the platform 1, and a first motor 11 is fixedly installed on the L-shaped plate 10.

[0034] In the process of filtering the molten ceramic sand, the driving shaft 21 and the cam 22 can be controlled to rotate by utilizing the transmission effect of the main pulley 23, the auxiliary pulley 24 and the belt 25, and by setting the diameter of the main pulley 23 to half of the diameter of the auxiliary pulley 24, it can be ensured that when the filter cartridge 8 rotates one circle, the cam 22 rotates half a circle, and then the transmission characteristics of the cam 22 and the elastic force of the spring 7 are utilized to control the filter cartridge 8 to perform intermittent horizontal reciprocating motion on the carrier box 5 during the process of horizontal rotation with the vertical axis 4 as the axis, and the filter cartridge 8 performs intermittent horizontal reciprocating motion.
