Environmental protection multi-function and high-efficiency special vehicle

Abstract

The invention relates to an environment-friendly, multifunctional and high-efficiency special-purpose vehicle, which comprises a vehicle body, a vehicle panel, a frame above the vehicle panel, a suction device with a retractable end on the frame, and a suction device connected to the vehicle panel. A collection box for pretreatment; the outer cylinder and the inner cylinder are arranged upwardly from the water outlet to the discharge outlet; there are several filter holes hollowed out on the peripheral surface of the inner cylinder, and the inner peripheral surface of the inner cylinder is provided with The feeding plate with screw thread extension, the direction of rotation of the inner cylinder is the same as the screw direction of the feeding plate; it also includes a feeding pipe communicated with the collecting box and extending into the inner cylinder. By adopting the above technical scheme, the moisture in the sludge is diverted to the water outlet under the action of its own weight, and the solids in the sludge move toward the discharge outlet under the action of the feeding plate and are removed from the discharge outlet, thereby realizing solid-liquid separation. The solids in the sludge at the outlet and the moisture in the sludge at the water outlet can be received and further processed through different containers respectively.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging, in particular to an environment-friendly, multi-functional and high-efficiency special vehicle. Background technique [0002] At present, the urban underground drainage pipe is an important system to prevent urban waterlogging and drainage. As the service life of the drainage pipe increases, a certain amount of silt will accumulate in the drainage pipe, which reduces the drainage efficiency. The drainage pipe needs to be dredged to maintain smooth drainage. . [0003] Existing dredging work is generally carried out by dredging equipment, such as a pipeline dredging equipment disclosed in a Chinese patent with application number CN201820290248. After the sludge is sucked by the silt pipe, it is collected in the pre-installed collection box on the equipment for temporary storage or pretreatment. Conventional pretreatment operations include throwing flocculants into the collection box, s...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art solutions have the following defects: the existing dredging equipment often has a single function, and there are many inconveniences in the actual use process. After the dredging equipment collects the sludge, it cannot further process the sludge. After the flocculant is put in, the sludge is settled, but the water content in the sludge is high, and it cannot be directly purified after being discharged from the collection box. How to reduce the humidity of the sludge, there is still room for improvement
