Description

Technical Field

[0002] With the acceleration of China's urbanization process and the expansion of urban scale in recent years, the increase in urban population and the aggravation of urban population density are inevitable. During the peak hours of daily residents' travel, there is a large flow of people, and the conventional public transportation methods can no longer meet the demand for passenger transportation. To solve the increasingly serious traffic pressure, large and medium-sized cities are currently vigorously developing the construction of subways. As a result, a large amount of shield muck is formed during the construction process. The water content of the shield muck is relatively large. If the muck is directly loaded and transported out, the overflow along the road will cause damage to the environment, and the external transportation has become a difficult problem that the construction unit urgently needs to solve.

[0003] The existing sludge solidification devices on the market generally pour the sludge into the device, and then separate the muddy water through non-woven fabrics. After the separation is completed, the sludge part is pressed. On the one hand, the remaining water is squeezed out, and on the other hand, the flattened sludge blocks are more convenient for transportation. However, in the actual use process, during the sludge treatment process, the harmful gases formed by the respiration of bacteria in the sludge and other conditions may diffuse into the air. If not treated in time, staying in this environment for a long time may cause irreversible damage to the health of the staff. For this reason, we have proposed a solidification device for shield muck sludge. Content of the Utility Model
