[0028] The first filter layer 16, the second filter layer 17 and the third filter layer 18 are respectively provided with a guide plate c21, a guide plate b20 and a guide plate a19 on their upper sides. The upper end outer walls of the guide plates a19, b20 and c21 are provided with upper and lower openings 22 for liquid to pass through. The liquid and unfiltered impurities passing through the first filter layer 16, the second filter layer 17 and the third filter layer 18 will be filtered for the second time by the guide plates c21, b20 and a19, and the filtered liquid will be discharged from the opening 22 and collected in the depression to avoid accumulation.

[0029] like Figure 3 As shown, a thickened plate 23 is fixedly connected at the center of the lower end outer wall of the guide plate a19 , the guide plate b20 and the guide plate c21 , and a positioning rod 24 is fixedly connected to the lower end outer wall of the plurality of thickened plates 23 .

[0030] By setting a thickened plate 23 to block part of the opening 22, the filtered impurities can be blocked and stored by the thickened plate 23, and the height of the guide plate a19 is increased by the positioning rod 24, so that the inclination angles of the guide plates a19, b20 and c21 reach the optimal angle.
