Secondary filtering mechanism of glass fiber reinforced plastic filter

The secondary filtering mechanism comprises a box body, a confluence groove and a fixing seat, the outer surface of the box body is fixedly connected with a first limiting block, the middle of the upper surface of the box body is fixedly connected with the fixing seat, and the edge of the upper surface of the box body is fixedly connected with a first filtering net. A first penetrating groove is correspondingly formed in the position, opposite to the first filter screen, of the upper surface of the box body, flow dividing grooves are symmetrically formed in the side face of the side, away from the first limiting block, of the flow collecting groove, the ends, away from the flow collecting groove, of the flow dividing grooves communicate with the output groove, and a first groove is formed in the end, close to the flow collecting groove, of the flow dividing grooves. A storage groove is formed in the inner surface of the fixing base, second limiting blocks are symmetrically connected to the side face of the st
