How to achieve efficient recovery rate

 

Why the stacked screw machine can achieve efficient recycling. The stacked screw machine uses multiple end plates and organic sludge dewatering to achieve efficient recovery of solid particles! Specifically, let's take a look at it: according to the principle of gravity dewatering filtration + extrusion, using energy-saving structures and Miniaturized design, the installation process is very simple; especially the installation area of ​​ND and DS is only 70%, which is more compact and can be installed on equipment and mobile car dehydration; the pressure of the stacking screw machine can handle oily sludge and oily Sludge floc floating, filter cloth type, centrifugal type, etc., are difficult to effectively treat, but this machine does not have an effective treatment for oily sludge that may cause blockage of the offline structure. Yes, high solid recovery rate can be obtained .

 

The continuous operation of the stacker is achieved by a button operation. When automatic operation of the machine is achieved, continuous operation can be achieved without using a standard additional liquid polymer flocculant dissolving device. We all know that the required sludge dewatering is polyacrylamide as a dehydrating agent. Cationic polyacrylamide and cationic polyacrylamide flocculants are usually strong. They can rise quickly and steadily through the network and the absorption of urban sewage. And the rapid sedimentation and clarification of solid-liquid separation and the effect of sludge, therefore, the sludge dehydration of cationic polyacrylamide, it gave us a fixed impression.

Sludge dehydration polyacrylamide and cations? As a manufacturer of polyacrylamide, this problem is not accurate. Cationic PAM is suitable for flocculation, sedimentation and dehydration of organic sewage sludge. Inorganic wastewater can also achieve flocculation and sludge dewatering by anionic or non-ionic means. Sludge dewatering with anionic polyacrylamide sewage sludge includes: mine sewage treatment, sewage treatment, coal mine sewage treatment, sewage treatment, stone washing sand sewage treatment, sewage treatment plant, electronics, etc., these sewage inorganic wastewater, so use Anionic polyacrylamide or non-ionic PAM can also achieve the purpose of wastewater flocculation and dewatering sludge.

 

The flow of the sludge after gravity dehydration is almost completely lost. The distance between the filter belt and the filter press belt gradually decreases, and the material begins to have a slight pressure. When the filter belt runs, the pressure gradually increases. The role of the wedge-shaped area expansion is gravity dehydration time. Extrude the stable and increasing floc and prepare to enter the pressure zone. The material is wedged into the nip, and the extruded material is in this area. The pressure along the direction of the filter belt and the reduction of the diameter of the extrusion roller increases, the material squeezes and shrinks, and the gap between the free water is squeezed. The content of the filter cake can be reduced to a lower level after the area tail water is continuously pressed.
