Environment-friendly dirt removing system

Abstract

The invention relates to an environment-friendly dirt removing system. A dirt removing device comprises a dirt removing unit, a dirt separation unit and a dirt collecting box, wherein the dirt separation unit comprises an outer box body, a first inner box body and a second inner box body; a waterweed removing device comprises a pulling unit, a cutting unit, a crushing unit and a waterweed collecting box; two discharge ports of the waterweed collecting box are both closed by control valves; one discharge port extends into the first inner box body through a waterweed pipe; and a waterweed material pump is arranged on the waterweed pipe. According to the system, the functions of dirt removing and waterweed removing are integrated, and the two operations can be carried out simultaneously, thus, the system is suitable for river channel treatment operations in various environments with high working efficiency. The waterweed removing device can fully utilize the dirt separation unit of the dirt removing system device, so that the dirt separation unit can not only separate the dirt but also dehydrate the waterweed. Due to the fact that a device for dehydrating the waterweed is not needed to be additionally designed as well as no space of a ship body needs to be occupied, the technical effects of saving the manufacturing cost of the device and reducing the space requirement for the shipbody are 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...

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.

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
