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.
This device has the following deficiencies: (1) the aquatic plants after cutting are directly put into the channel, if not directly put into the channel, it is necessary to add a silo for storing aquatic plants
Due to the high moisture content of the cut aquatic plants, the weight of the materials in the silo is heavy, and the depth of the hull pool is deep, which increases the performance requirements for the hull; in addition, in order to recycle the aquatic plants, a drying process is required, and the processing cycle is longer. (2) The silt cleaning device cannot salvage the silt at the bottom of the water, and the silt will eventually be deposited at the bottom of the water

Embodiment 1

[0042] refer to figure 1 , a garbage disposal device proposed by the present invention, comprising a hull 0, a dredging unit 1, a silt separation unit 2 and a silt collection box 3 which are sequentially arranged on the hull 0 according to the process flow sequence; the dredging unit 1 is used for grabbing The sludge is taken and fed into the sludge separation unit 2; the sludge separation unit 2 is used for filtering and dehydrating the sludge; the silt collecting tank 3 is used for collecting the filtered and dehydrated sludge.

[0043] refer to Figure 6 , the dredging unit 1 includes a mud loosening mechanism connected to the bottom of the hull O, and a silt pump 223 that feeds silt from the mud loosening mechanism into the sludge separation unit.

[0044] refer to Figure 5 , the mud loosening mechanism includes a feed box 11 with a mud flow passage, a rotating shaft connected in the mud flow passage, and a plurality of shifting plates 13 distributed along the axial dir...

Embodiment 2

[0072] The difference between this embodiment and Embodiment 1 is that this embodiment also discloses the following features:

[0073] refer to Figure 7 , the guide screen 207 is movably connected to the outer box 203, and one side of the guide screen 207 is drivingly connected to the piston end of the blanking cylinder 215; the outer box 203 is also provided with The impurity outlet 213, the impurity outlet 213 is located directly below the sewage discharge hole, the guide screen 207 can be driven by the feeding cylinder 215 to the impurity outlet 213, the side of the impurity outlet 213 An impurity collection box 214 is provided.

[0074] It is mentioned in Embodiment 1 that when the impurities in the first inner box 201 need to be taken out, the cylinder 212 needs to be used to control the material baffle plate 206 to move upward. However, due to the deep depth of the first inner box 201 and the limited length of the suspender 209, it is found in actual operation that th...

Embodiment 3

[0079] The difference between this embodiment and the foregoing embodiments is that this embodiment also discloses the following features:

[0080] refer to Figure 10 , the dredging device is installed on the bow of the hull, the water weed removal device is installed on the stern of the hull, the water tank removal device includes a salvage unit 4, a cutting unit, a crushing unit and a grass box 6; the grass box 6 There are two material outlets, both of which are closed by control valves, and one of the material outlets extends into the first inner box 201 through a forage pipe, and a material pump 56 is installed on the forage pipe.

[0081] The salvage unit 4 is used to salvage aquatic plants on the river surface and send them into the grass collecting box 6 . In this process, the aquatic plants are cut by the cutting unit to reduce the size of the strip-shaped aquatic plants, and then the aquatic plants are crushed by the crushing unit to further reduce the size of the a...

Abstract

The invention relates to an environment-friendly decontamination system. The desilting device includes a desilting unit, a silt separation unit and a silt collection box; the silt separation unit includes an outer box body, a first inner box body and a second inner box body; the aquatic weed removal device includes Salvage unit, cutting unit, crushing unit and grass collection box; the two outlets of the grass collection box are closed by control valves, one of the outlets extends into the first inner box through the grass pipe, and the grass pipe is installed There is a feed pump. This system integrates the functions of silt cleaning and aquatic weed removal. The two operations can be carried out at the same time. It can be applied to river channel management operations in various environments and has high operating efficiency. The aquatic weed removal device can make full use of the silt separation unit of the desilting device, so that the silt separation unit has the functions of separating silt and dehydrating aquatic plants. Since there is no need to additionally design a device for dehydrating aquatic plants, and no need to occupy the space of the hull, the technical effect of saving the manufacturing cost of the equipment and reducing the space requirement for the hull is achieved.

Description

technical field [0001] The invention relates to the field of desilting, in particular to an environment-friendly decontamination system. 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 classif...
