Self-moving type bottom mud separating and collecting device

Abstract

The invention discloses a self-moving type bottom mud separating and collecting device in the field of desilting and dredging devices. The self-moving type bottom mud separating and collecting device comprises a walking filtering mechanism. The walking filtering mechanism comprises a left end plate and a right end plate which are connected through a crawler tooth plate. A filtering grating is arranged between the left end plate and the right end plate. The left end plate is rotationally connected to a left supporting pipe, and the right end plate is rotationally connected to a right supporting pipe. Installing plates are arranged at the lower portions of the left supporting pipe and the right supporting pipe, and an arc protection cover is arranged between the two installing plates. A spiral blade shaft is arranged below the arc protection cover. A mud pump is arranged above the arc protection cover. A mud sucking opening is formed behind the arc protection cover and connected with an inlet of the mud pump through an inlet pipeline, and an outlet pipeline of the mud pump is connected with an outer mud discharging pipeline penetrating the right supporting pipe. The right supporting pipe is provided with a rotation driving mechanism through a seat plate, wherein the rotation driving mechanism drives the walking filtering mechanism to rotate. The self-moving type bottom mud separating and collecting device can efficiently collect riverway bottom mud and convey the riverway bottom mud out, energy saving and environment friendliness are achieved, and the desilting efficiency is higher.

Description

technical field [0001] The invention belongs to the field of dredging devices, in particular to a device for separating and collecting river bottom mud. Background technique [0002] Sediment is a mixture of clay, silt, organic matter and various minerals, formed by depositing at the bottom of a water body after long-term physical, chemical and biological actions and water transport. The sediment with a thickness of 0 to 15 cm on the surface is called surface sediment, and the sediment with a thickness of more than 15 cm is called deep sediment. With the development of industry, a large amount of industrial wastewater is discharged into the river, which destroys the ecological balance and causes the pollutant content in the sediment to exceed the standard. This requires us to dredge the river sediment; in addition to the polluted sediment in urban rivers, there are often Accompanied by domestic and construction waste, it increases the difficulty of dredging. [0003] In th...

Problems solved by technology

Its disadvantages are: the device needs to be operated manually, and the risk factor of the operation on the river is high; the degree of automation is low, and the operation of the staff is time-consuming and laborious; the work efficiency is low, it is difficult to clean the river sediment, and the dredging effect is poor

However, it is difficult to operate excavators on engineering ships, and the requirements for operators are too high. The cost of dispatching two engineering ships and excavators at the same time is high, energy consumption
