Description

Technical field:

[0001] The utility model belongs to the technical field of sludge solidification, and in particular relates to a sludge solidification stirring device. Background technology:

[0002] Sludge solidification construction is to add solidifying agents into the sludge pit, stir and mix, destroy the microbial cell structure in the sludge, promote the release of water in the cells, and fix toxic and harmful substances in the network chain formed by solidification through a series of complex physical and chemical reactions, so that it is transformed into a solid similar to soil or with high cementation strength, thereby reducing the water holding capacity of the sludge and achieving the purpose of sludge solidification. The process has high performance requirements, for this reason, a series of sludge in-situ solidification treatment devices have been developed and designed, and the stirring device can be divided into a vertical stirring head and a horizontal stirring head according to the stirring head. For example, the patent with announcement number CN219259803U discloses a sludge in-situ solidification treatment device for river channel regulation construction, in which the stirring blade is a horizontal stirring head, and the second motor drives the second rotating shaft and the telescopic rod to rotate together, and the telescopic rod drives the spray box and the connecting seat to rotate together, and the fixed rod and the stirring frame rotate together with the connecting seat, that is, while the stirring frame is stirring in the sludge, the curing agent is sprinkled into the sludge through the nozzle, so that the curing agent and the sludge are mixed evenly, and the effect of the curing agent is fully exerted, so as to achieve the purpose of improving the sludge solidification efficiency by using the sludge in-situ solidification treatment device in river channel regulation construction; the patent with announcement number CN2149876U discloses a rotary soft base in-situ solidification stirring device, in which the stirring blade is a horizontal stirring head, and the hydraulic motor drives the bevel gear one to rotate, and the bevel gear one drives the stirring blade on the rotating seat to rotate through the bevel gear two and the rotating rod, and the stirring The blades can stir the sludge during the rotation process, and the bevel gear one drives the rotating tube to rotate through the bevel gear three at the same time. During the rotation process, the rotating tube reversely mixes the sludge through the reamer on the outside of the rotating sleeve, and during the rotation of the rotating sleeve, the bevel gear four drives the reamer to rotate through the bevel gear five. During the rotation process of the rotating sleeve, the reamer can increase the degree of disorder of the sludge by self-rotation, thereby effectively increasing the stirring efficiency; the patent with announcement number CN104563093B discloses a contaminated soil in-situ solidification and stabilization treatment device, the stirring head is a vertical stirring head, and by adopting a special mixing arm, the soil can be efficiently cut, turned, and mixed, and three-dimensional multi-directional deep stirring is achieved. The rotating cylinder is equipped with a spirally arranged stirring blade, which has the advantages of good mixing and stirring effect, strong crushing ability, large torque, small motion resistance, and not easy to damage. A large amount of dust is prone to occur during the solidification process of soft soil, resulting in a decrease in air quality. Although the above stirring device can achieve a good stirring effect, it cannot solve the dust problem. In addition, compared with the horizontal stirring head, the vertical stirring head can better achieve the vertical stirring of sludge, but the existing vertical stirring head is fixed and can only stir within the fixed point range, and the stirring range is limited, which limits its further application.
