Introduction: In view of the problems of different depths of different terrain waters, which lead to the difficulty of normal treatment of black and smelly water bodies and silt, we have designed an all-in-one desilting and purifying machine that can adjust and adapt to the terrain and process mud and black and smelly water in a modular process. The machine can use the rope row telescopic and fixed claws to quickly stabilize in a variety of terrain, the combination of a variety of adjustable treatment methods so that it can handle a variety of water conditions, applicable to a wide range. When the machine is running, the fixed claw is put down and fixed on the bottom mud layer and the ground soil layer. The working accuracy is increased by the lowered sludge extractor to prevent the influence of the weather. The obtained mud is double-squeezed into the cavity and moderately dried to remove water to obtain mud cake, which is convenient for storage and transportation. The regional treatment of sewage in chemical, physical, biological and other ways makes it reach the standard. Innovation points: 1. The extractor uses a reamer to extract the bottom silt at the bottom of the water, and the vacuum pump extracts the mud to reduce the influence of weather and other factors, and the working area and silt depth are more accurate; The modular structure makes it easy to assemble and cooperate freely, and the combination of multiple sensor control and HDP process saves energy as much as possible. 3, double extrusion and moderate drying mud to obtain mud cake convenient storage and transportation 4. Multi-level mechanical structure area through the combination of aeration and oxygen, chemical, precipitation, filtration methods to treat sewage to purify it. Application prospects: Social needs: the state attaches great importance to ecological restoration, the recurrence of silt and sewage, the overall supply is less than demand; Industry status: the price of silt extractors on the market is high, there are many influencing factors, the extracted silt is difficult to transport and store, the degree of automation, the way of purifying water is single separation; Promotion value: reasonable mechanical structure and the main structure that can adapt to a variety of waters, the new process treatment method of silt is convenient to transport, reduce costs and increase functions, modular structure is convenient to separate processing and assembly and can adapt to a variety of situations after change, expand the sales scope of products, the development prospect is huge.
