Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dewatering devices, in particular to a shield mud dewatering environmental protection device. BACKGROUND

[0002] Shield mud, also known as shield construction mud, is a high water content and high viscosity slurry formed by mixing soil and water during shield tunnel construction, which is mainly used to balance groundwater pressure, support tunnel wall, prevent collapse and transport excavated spoil. Shield mud has complex composition, usually containing clay, sand, water, additives, etc., and has good fluidity and stability. However, if not properly handled, it can pollute the environment, so it needs to be dewatered, separated and purified by a special treatment device to realize resource utilization and meet the discharge standard.

[0003] The shield mud dewatering environmental protection device is a device specially used for treating high water content mud generated during shield construction. Through multi-stage screening, flocculation and pressure filtration, solid particles and water in the mud are efficiently separated, achieving reduction and harmless treatment of the mud, and finally obtaining mud cake for resource utilization and clean water for standard discharge.

[0004] The plate and frame filter press forces water in the mud and sand out of the filter plate hole under high pressure, which can quickly reduce the water content. However, when faced with shield mud mixed with micron-sized clay particles and tens of millimeter-sized pebbles, coarse and hard particles are easily wedged and bridged to block the filter holes, resulting in a sharp decrease in effective filtration area and a cliff-like drop in dewatering efficiency. In addition, high pressure impact and shear accelerate filter cloth damage and filter plate deformation, forcing frequent on-site shutdown, frame disassembly, washing and replacement of spare parts, severely weakening continuous operation capability. Therefore, a shield mud dewatering environmental protection device is proposed to solve the above problems. SUMMARY
