An environment-friendly dredging device

Abstract

The invention relates to an environment-friendly dredging device. The dredging unit includes a mud loosening mechanism and a dredging pump; the sludge separation unit includes an outer box body, a first inner box body and a second inner box body installed on the hull; the sludge separation unit It also includes a dehydration tank, which is provided with spiral blades; a water pump and a medicine tank are also installed on the hull, and the water inlet of the water pump extends to the bottom of the outer box through a water pipe; the medicine tank is filled with deodorizing liquid, medicine The liquid outlet of the tank extends to the bottom of the outer box through the liquid outlet pipe; the first inner box, the second inner box, the stirring paddle and the screw blade are all driven to rotate by the transmission mechanism. The invention can automatically clean the silt at the bottom of the river or lake, and can filter and dehydrate the silt, and has the technical effects of simple operation, high working efficiency, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of dredging, in particular to an environment-friendly dredging device. Background technique [0002] There are many rivers and lakes in our country, and the problem of sedimentation is very serious. The sedimentation causes the river bed to rise, which not only affects flood control and threatens the safety of people's lives and property, but also makes it difficult for various functions such as drainage, irrigation, water supply, and navigation to be properly performed. Seriously restricting the comprehensive utilization of water resources and exacerbating the deterioration of the water environment, it is necessary to regularly dredge the drainage to ensure the smooth flow of the river. [0003] The invention patent with the patent number of 201811268780.2 discloses a river dredging device for water conservancy projects. The device extracts the sludge from the bottom of the water and sends it into the classification ...

AI Technical Summary

Problems solved by technology

This device has the following defects: (1) the filtering efficiency of the screen is limited. If the filtering effect of the screen is to be guaranteed, the amount of sludge transported by the lifting device needs to be limited, thereby restricting the dredging efficiency; To a certain extent, it can accelerate the separation of impurities and silt, but the water content of silt is increased after washing the silt with water, which not only wastes water resources, but also increases the burden of subsequent transportation of silt; (3) the whole device provides walking power through the walking device , due to the complex working environment at the bottom, there may be undulating terrain, which will not bring certain resistance to the advancement of the device, resulting in the inability of the cleaning device to effectively sweep the silt into the lifting device, reducing the efficiency of dredging; (4) If the amount of impurities in the sludge is too large, it will block the screen and cause the dredging process to fail to proceed smoothly.

In order to ensure the effectiveness of the dredging work, it is necessary to transport the device from the bottom of the river to the ground and remove the impurities, and then put the device back to the bottom of the river. This process reduces the efficiency of dredging and increases the number of staff workload
