[0044] Working principle: After the silt is dehydrated and crushed by the dehydration equipment and the crushing equipment, it is transported to the mixing equipment 2 by the conveyor belt 1. By adding the silt and water into the mixing equipment 2, the fluidized solidified soil is formed by stirring.

[0045] When the silt is added to the inside of the mixing equipment 2, the two mixing chambers are used alternately. One mixing chamber is used for mixing and discharging, and the other mixing chamber is used to collect the silt transported by the conveyor belt 1 to prepare for subsequent mixing, thereby saving the production time of the fluidized solidified soil and relatively increasing the production of the fluidized solidified soil, meeting the needs of uninterrupted transportation operations of the pumping equipment 5.

[0046] Before the sludge is added to the inside of the mixing equipment 2, it is first screened through the sieve plate 41 to screen out larger particles of impurities. When the sludge falls onto the sieve plate 41, the impact force generated by the fall causes the spring telescopic rod 36 to elastically expand and contract, thereby driving the sieve plate 41 to shake, thereby improving the screening efficiency of the sieve plate 41. After the screening is completed, the hydraulic rod 42 extends, driving the sieve plate 41 to rotate upward, so that large particles of impurities slide out of the sieve plate 41.
