Abstract

The invention discloses a productization forming system for slurry shield construction waste slurry, and relates to the technical field of waste slurry treatment. A slurry shield construction waste slurry productization forming system comprises a supporting frame, a first-stage dehydration system, a second-stage dehydration system and a material forming system, wherein the first-stage dehydration system, the second-stage dehydration system and the material forming system are communicated in sequence. The primary dehydration system is arranged on the support frame and is used for dehydrating the waste slurry to obtain concentrated slurry; the secondary dehydration system is arranged on the support frame and is used for compressing and dehydrating the concentrated slurry to obtain a mud cake; the material forming system is arranged on the supporting frame and used for smashing the mud cakes into mud powder, mixing the mud powder with additional materials and pressing the mixture into blocks. According to the invention, the brick is formed through multi-stage dehydration and compression molding, and the baking-free brick product with uniform texture and up-to-standard strength can be directly obtained through the process.
