Vertical sludge cleaning treatment machine for river channel dredging

Abstract

The invention relates to a vertical sludge cleaning treatment machine for river channel dredging. The vertical sludge cleaning treatment machine comprises a workbench, a drying device, a block cuttingdevice and a crushing device, wherein the drying device is installed at the right end of the upper end face of the workbench in a sliding fit mode; the block cutting device is arranged on the left side of the drying device and is connected with the upper end face of the workbench in a sliding fit mode; and the crushing device is arranged on the left side of the workbench. According to the vertical sludge cleaning treatment machine for river channel dredging, river sludge is cleaned and reutilized by adopting the design concept of multi-stage treatment, so the waste is turned into the valuable, and the utilization rate and the forming degree of sludge are improved; and dried sludge blocks are crushed and refined by adopting the crushing device, so the crushed sludge blocks can be easily mixed with other substances during subsequent use.

Description

technical field [0001] The invention relates to the field of sludge treatment machinery, in particular to a vertical sludge cleaning and treatment machinery for dredging river channels. Background technique [0002] River sludge refers to sedimentary cohesive soil deposited in still water and slow water flow environment, formed by biochemical action, natural water content greater than liquid limit, and natural void ratio greater than or equal to 1.5. River sludge is composed of organic matter, inorganic matter and Composed of clay, river sludge is often gray-black in color, high water content and rich in organic matter are the most notable characteristics of river sludge, and its low mechanical strength, high compressibility, poor water permeability, low shear strength, etc., in daily river sewage Mud can often be used as fertilizer, mussel breeding, drying bricks, etc., or the sludge can be treated by chemical and physical methods to turn waste into treasure. In the process...

AI Technical Summary

Problems solved by technology

[0003] 1. Sludge under normal conditions is viscous and fluid. When it is processed directly, it will move with the movement of the equipment, and then form a drawing shape and stick to the equipment, which has poor formability and pollutes the equipment. At the same time, the equipment is not easy Apply force and pressure on the sludge, and then it is not easy to treat and reuse the sludge;

[0004] 2. The dry block formed by the sludge after drying is relatively large and thick, which is not convenient for subsequent treatment such as crushing directly. At the same time, in addition to being rich in organic matter that can be used as fertilizer, the sludge also contains metals, stones, harmful Substances and other impurities, direct use may affect the growth of plants or farmed animals
