Residue soil polymer production device for shielding operation

Abstract

The invention relates to a residue soil polymer production device for shielding operation. The residue soil polymer production device comprises a heating type stirring kettle, an air source bottle, a pressure reducing valve, a cooling extruder and a packaging machine, wherein after a residue oil polymer raw material is added to the heating type stirring kettle, the air source bottle is opened, air in the air source bottle flows into the heating type stirring kettle through the pressure reducing valve, heating and violent stirring are performed in the heating type stirring kettle, when the residue soil polymer raw material is melted into a high-viscosity fluid full of bubbles inside, the fluid type residue soil polymer raw material enters the cooling extruder to be cooled into solids, a granular residue soil polymer product is formed and enters the packaging machine for product subpackaging and sealing. The residue soil polymer production device is scientific and reasonable in design, bubbles are increased in polymers by means of an air-entrapping device, so that the polymers are made into products with small granularity, the dissolution time of the residue soil polymers can be reduced in use, and application of the residue soil polymers in practical production is facilitated.

Description

Technical field [0001] The invention relates to the field of muck polymer production equipment, in particular to a muck polymer production device used for shield tunneling operations. Background technique [0002] During the operation of the shield machine, due to the different geological conditions, such as a single sandy soil layer or a sandy gravel layer with a single particle size, the content of fine particles is small, the permeability is strong, and sandblasting, mud blasting and water spraying are easy to occur. , Resulting in instability of the excavation surface and collapse of the stratum, which affects the normal construction process. The workability of the muck can be improved by appropriately adding muck polymer to stabilize the excavation surface. However, in the process of using muck polymer, the most likely problem is the formation of agglomeration during dissolution, resulting in a longer dissolution time, which seriously affects the application and promotion of...
