Deposition press combined solid-liquid separation column

Abstract

The invention discloses a sink squeezing composite typed solid / liquid separation tower, comprising a material storage, a slurry inlet valve, a drainage liquid valve, a drainage suspension liquid valve, a vertical conveying machine, a driving bridge frame, a squeezing machine, a base and a control system; the material storage bin is fixed on the base; the slurry inlet valve is arranged on the top of the material storage bin; the drainage liquid valve and the drainage suspension liquid valve are arranged on the wall of the material storage bin; the drainage liquid valve is arranged on the drainage suspension liquid valve; the vertical conveying machine is arranged at the center of the material storage bin; the outlet end of the vertical conveying machine right faces to the bottom end of the material storage bin; the vertical conveying machine is embedded in the middle of the driving bridge frame which is fixed on the internal wall of the material storage bin; the squeezing machine is transversely and obliquely arranged below the material storage bin and communicated with the material storage bin; the squeezing machine is fixed with the lower shell of the material storage bin and the base; the slurry inlet valve, the drainage liquid valve, the drainage suspension liquid valve, the vertical conveying machine and the squeezing machine are respectively connected with the control system. The sink squeezing composite typed solid / liquid separation tower has reasonable structure, and can achieve the quick separation and processing of the slurry with investment-saving, high efficiency and low separation cost.

Description

Technical field [0001] The invention relates to a solid-liquid separation device, in particular to a solid-liquid separation device that combines the self-weight precipitation of solid particles in the solid-liquid with external squeezing and dewatering. The squeezing compound solid-liquid separation tower with initial rapid separation. Background technique [0002] With the increasing emphasis on environmental protection and the rapid development of urbanization, the dredging, dredging, and deepening of many inland rivers and lakes have been closely linked to urban reconstruction and industrial development. It is no longer allowed to be stored around it, and it needs to be dewatered at a high speed by a rapid separation device to facilitate the use of the separated solid mud as a resource. The most commonly used method of the prior art rapid separation solid-liquid separation device to treat fluid mud is to use a decanter centrifuge as the terminal separation; but the original f...

Problems solved by technology

However, 1. Due to the complex composition of the mud, the sedimentation speed and density are not consistent, which will cause the solid slag settled in the cone collector to be inconsistent in hardness and dry humidity, resulting in the solid slag transported to the bottom screw conveyor is a kind of In the state of free fall, sometimes the bridge is blocked, sometimes collapsed, and the liquid is injected, which makes the reliability of the separation work poor; The efficiency of solid-liquid separation is reduced, and the effect of initial fluid mud separation is not ideal
