Abstract

The invention discloses a bottom mud recycling device. The device comprises: a support; a draining barrel, which is obliquely arranged on the support, wherein a feeding port is formed in the area, close to the lower end, of the side wall of the draining barrel, and a steel wire mesh is arranged at an opening in the upper end of the draining barrel; a drying mechanism, which comprises a first fixing disc, a rotating cylinder, a second fixing disc and a driving gear, wherein a plurality of air inlets are annularly formed in the first fixing disc and communicate with an air heater, a cutting knife is arranged on the inner wall of the rotating cylinder, meshing teeth are annularly arranged on the outer wall of the rotating cylinder, and the meshing teeth are meshed with the driving gear; a conveying cylinder, wherein one end of the conveying cylinder is connected with the second fixing disc, a second auger is arranged in the conveying cylinder, the conveying direction of the second auger is in a direction away from the rotating cylinder, and a plurality of air outlets are formed in the surface of the conveying cylinder at intervals; and a batching groove, wherein the upper end of the batching groove is open, and the batching groove is located below the other end of the conveying cylinder. The invention further provides a bottom mud recycling method. According to the invention, bottom mud can be quickly and automatically dried and resourcefully treated.

Description

technical field [0001] The present invention relates to bottom sludge treatment. More specifically, the present invention relates to a bottom sludge reuse device and method. Background technique [0002] A large amount of sediment will be produced during the dredging process of the river channel. However, at present, the obtained sediment is usually stacked in the open air as solid waste, which not only occupies a large amount of space, but also easily produces secondary pollution. Therefore, there is an urgent need to design a technical solution to at least partially realize the resource reuse of sediment. Contents of the invention [0003] An object of the present invention is to provide a bottom sludge reuse device and method, which can quickly and automatically dry and recycle the bottom sludge. [0004] In order to achieve these objects and other advantages according to the present invention, according to one aspect of the present invention, the present invention p...
