Problems solved by technology

The flocculation mixing tank only allows flocs to form, and then directly flows into the solid-liquid separation device without any concentration, so the efficiency of solid-liquid separation is low and the water content is high
[0003] In the prior art, the flocculation formed after stirring in the flocculation mixing tank usually flows directly into the solid-liquid separation device. During the self-flowing process, since the material has been continuously entering and the stirring has been continuously running, the flocculation time is also short. Therefore, it is inevitable that some materials that have not been flocculated will also be mixed into the body, resulting in the phenomenon of material running out of the solid-liquid separation device
The flocculation mixing tank mostly uses stirring to keep the flocs from settling, and then flows into the solid-liquid separation device through overflow. This solid-liquid separation is completely realized by the gravity of the material and the thrust of the stirring shaft itself. Due to the limited extrusion force , the moisture content cannot be lowered, and the agitator shaft itself is prone to slow propulsion speed or internal blockage of the solid-liquid separation device due to its weak thrust

Description

【Technical field】 [0001] The invention belongs to the technical field of water treatment devices, and specifically refers to a flocculation concentration device with a grid structure and a filtrate recovery tank with a grid structure. 【Background technique】 [0002] In the field of water treatment, the main function of the flocculation mixing tank is to fully mix the material and flocculant to form flocs, and then flow the flocs into a solid-liquid separation device such as a screw dehydrator for concentration and dehydration by gravity. The flocculation mixing tank only allows flocs to form, and then directly flows into the solid-liquid separation device without any concentration, so the efficiency of solid-liquid separation is low and the water content is high. [0003] In the prior art, the flocculation formed after stirring in the flocculation mixing tank usually flows directly into the solid-liquid separation device. During the self-flowing process, since the material h...
