River channel dredging equipment

Abstract

The invention discloses river dredging equipment, and relates to the technical field of environmental protection. The equipment comprises a mud pump, an overwater platform, a stirring bin, a vibrating screen, a cyclone separator and a dosing machine A, the stirring bin, the vibrating screen and the cyclone separator are arranged on the water platform and are connected in sequence; the mud pump is connected with the stirring bin through a hose; the dosing machine A is connected with the hose; the stirring bin comprises a bin body and a stirring device, the stirring device comprises a stirring motor, a stirring rod and stirring paddles, the stirring rod is connected with the stirring motor, the stirring paddles are located on the stirring rod, and multiple groups of stirring paddles are arranged on the stirring rod; the stirring motor is positioned at the top of the bin body; the stirring rod and the stirring paddle are positioned in the bin body; a plurality of rotational flow baffles are arranged in the bin body, and the rotational flow baffles and the stirring paddles are distributed in the bin body in a staggered mode. The river channel desilting equipment can be suitable for desilting treatment of large-area water areas of large rivers and large lakes, is movable, convenient and flexible, harmful substances are effectively removed after sludge treatment, heavy metal and total phosphorus are chelated and mineralized, and mud and tail water meet the environmental protection standard at the same time.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a dredging equipment for rivers and lakes. Background technique [0002] Most of the existing dredging equipment for rivers and lakes covers a large area, has many facilities, and is difficult to move. It is not suitable for the treatment of large rivers and other large-scale waters containing various sediments, and the existing dredging equipment is difficult to separate mud and water. Odor exists in the production environment, and the mud cake odor produced is difficult to dispel, and there is a problem that the tail water is not up to the standard, and it is necessary to add equipment to treat the tail water; in addition, the existing dredging equipment cannot remove the harmful substances in the sludge. Heavy metals and total phosphorus exceed the standard, and the transport of sludge is pollution transfer, causing new pollution to the environment. The total ...

[0002] Most of the existing dredging equipment for rivers and lakes covers a large area, has many facilities, and is difficult to move. It is not suitable for the treatment of large rivers and other large-scale waters containing various sediments, and the existing dredging equipment is difficult to separate mud and water. Odor exists in the production environment, and the mud cake odor produced is difficult to dispel, and there is a problem that the tail water is not up to the standard, and it is necessary to add equipment to treat the tail water; in addition, the existing dredging equipment cannot remove the harmful substances in the sludge. Heavy metals and total phosphorus exceed the standard, and the transport of sludge is pollution transfer, causing new pollution to the environment. The total phosphorus in the sludge is washed by rain and then returns to the water body of the river and lake after being collected. In the rainy season, the sediment After being washed by rainfall, the leachate can easily cause secondary pollution
