Sludge in-situ treatment device

Abstract

The invention provides a sludge in-situ treatment device for mechanical equipment and in particular relates to equipment with a hydraulic system, such as a tractor, a dredging ship and a wheel excavator. The sludge in-situ treatment device is mounted at the front end of a small arm of the excavator and is connected with the small arm of the excavator through a connecting assembly; the sludge in-situ treatment device has a main function of stirring bottom mud of a river channel and feeding a medicament. By utilizing the in-situ treatment device of the bottom mud of the river channel, the engineering operation cost produced by transporting sludge out can be reduced and the occupied area of a sludge storage yard is reduced; meanwhile, the medicament is used and a repairing capability of microorganisms on the bottom mud is improved, and a function of biologically digesting the sludge is realized; a water body microorganism ecological system is recombined, completed and optimized, and a self-purifying capability of a water body ecological system is promoted, so that the aim of repairing water body ecology is realized.

Description

technical field [0001] The invention relates to the field of mechanical technology, and in particular provides an in-situ sludge treatment device installed on the front end of the small arm of an excavator. Background technique [0002] At present, the water quality of the river and the silt at the bottom are black and smelly, seriously affecting the ecological environment. The siltation of the river has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal functions of the river and promote rapid economic and social development Continue to develop and carry out river dredging and dredging projects. The river channel will become deeper and wider through treatment, and the river water will become clearer. The production conditions and living environment of the people will be significantly improved, and the goal of "clear water, smooth river, green banks and be...

Drainage and dredging is a method of dry excavation or hydraulic excavation after the water is drained. It has the advantages of intuitive construction status and easy guarantee of quality; the disadvantage is that the construction of temporary cofferdams is increased due to the need to drain the running water in the river. At the same time, many river courses can only be constructed during the non-flood season, the construction period is limited, and it is easy to cause certain impact on the river slope and ecological environment

Underwater desilting generally installs the dredging machine on the ship, and the dredging ship is used as a construction platform to operate the dredging equipment on the water surface to excavate the sludge and transport it to the shore through pipelines; it is divided into grab dredging, pump dredging Suction dredging, cutter suction dredging, and bucket wheel dredging; their disadvantages are that grab dredging is prone to floating mud leakage, strong disturbance of sediment, and can not achieve the purpose of water quality improvement; pump suction dredging equipment is easy Causes blockage of the suction port; cutter suction dredging and bucket wheel dredging are likely to cause the diffusion of pollutants in the bottom mud and the phenomenon of back-silting. In addition, the low concentration of mud will increase the land occupation of the sludge dump
