A self-propelled sediment separation and collection device

Abstract

Self-propelled sediment separating and collecting equipment comprising a traveling filter mechanism. The traveling filter mechanism comprises a circular left extremity plate (1) and a right extremity plate (2). The left extremity plate (1) and the right extremity plate (2) are connected therebetween via several grouser plates (3) in a radial arrangement. Several filter gratings (4) also are arranged at intervals between the left extremity plate (1) and the right extremity plate (2). The left extremity plate (1) and the right extremity plate (2) are rotatively connected to a left support pipe (5) and to a right support pipe (6). Mount plates (8) are arranged below corresponding opposite extremities of the left support pipe (5) and of the right support plate (6). An arced shield (9) is arranged between the two mount plates (8). An auger conveyor shaft (11) driven by a first hydraulic motor (10) is arranged below the arced shield (9). A slurry pump (14) is arranged above the arced shield (9). A mud suction opening (12) is provided at the rear of the arced shield (9) corresponding to the auger conveyor shaft (11). The mud suction opening (12) is connected to an inlet of the slurry pump (14) via an inlet pipe (13). An outlet pipe (15) of the slurry pump (14) is connected to the external mud discharging pipe (16) running through the right support pipe (6). A rotatable driving mechanism for driving the rotation of the traveling filter mechanism is mounted on the right support pipe (6) via a base plate (18).

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 is high, and it is not environmentally friendly.

In order to facilitate the cleaning of the bottom mud and prevent the clogging of the suction device, the current sanitation department also uses a crushing and cutting machine to cut and crush the larger debris mixed in the bottom mud, and then uses the suction device to pump the bottom mud to the transportation pipeline to realize cleaning. However, the cutting of sundries by the crushing and cutting machine will also consume more energy, which is not energy-saving and environmentally friendly.
