Crushing device used before rolling construction of sludge solidified soil

Abstract

The invention discloses a crushing device used before rolling construction of sludge solidified soil, and belongs to the technical field of environmental protection. The crushing device comprises a housing, a crushing cavity, crushing rollers, crushing blades, connecting rods, a crushing motor, a mesh screen, a rotary motor, shock-absorbing bases, a feed hopper, a first rotating shaft, a vibration generator, a screw blade, a second rotating shaft and a discharge opening, wherein the housing is arranged at the tops of the shock-absorbing bases; the crushing cavity is arranged in the housing; the feed hopper is arranged at the center of the top end of the housing; the feed hopper communicates with the crushing cavity; the first rotating shaft is horizontally arranged below the crushing rollers; the crushing blades are arranged on the first rotating shaft through the connecting rods; the crushing motor is fixedly arranged at the middle of the left side of the housing; and the output shaft of the crushing motor is connected with the first rotating shaft. The crushing device used before rolling construction of sludge solidified soil is simple in structure, reasonable in design and time-saving and labor-saving, can be better used for quick and uniform crushing of solidified soil, and can further ensure the compactness and uniformity of the soil body after subsequent rolling and compacting construction.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a crushing device used before construction of silt-solidified soil rolling. Background technique [0002] Due to the construction and maintenance needs of water conservancy projects, port waterway projects, coastal projects, etc., as well as the comprehensive environmental management of rivers and lakes, and the protection of drainage systems, large-scale dredging and dredging projects are carried out in my country every year, resulting in a large amount of dredged silt; The dredged silt is difficult to be used directly due to its high moisture content, high content of fine particles, and low strength. Usually, the silt will be solidified; after the silt is solidified, it can be used as land fill in the project, which realizes waste utilization and eases the burden on the project. The lack of filler is a solid waste treatment method with high added value; at presen...

[0002] Due to the construction and maintenance needs of water conservancy projects, port waterway projects, coastal projects, etc., as well as the comprehensive environmental management of rivers and lakes, and the protection of drainage systems, large-scale dredging and dredging projects are carried out in my country every year, resulting in a large amount of dredged silt; The dredged silt is difficult to be used directly due to its high moisture content, high content of fine particles, and low strength. Usually, the silt will be solidified; after the silt is solidified, it can be used as land fill in the project, which realizes waste utilization and eases the burden on the project. The lack of filler is a solid waste treatment method with high added value; at present, there is no special machine for the crushing of silt-solidified soil lumps. Manual crushing is labor-intensive and low-efficiency, and after crushing The particle size of the agglomerates is different, which affects the filling quality. For a long time, the existing machinery for crushing soil is mainly agricultural machinery, and some crushing of dry materials, so it cannot be used for crushing solidified soil. construction; therefore, we need a crushing device for silt solidified soil rolling before construction
