Sea float waste salvaging device with dual functions of negative pressure suction and conveying

Abstract

The invention discloses a sea float waste salvaging device with double functions of negative pressure suction and conveying. The sea float waste salvaging device comprises a suction unit, a conveyingunit and a negative pressure unit. The suction unit comprises a collection opening, a stainless steel folding hose, a hydraulic telescopic device and a conveying belt bottom protective cover. The conveying unit comprises a conveying belt, a driving roller, a driven roller, a conveying belt protection side plate, a pre-dewatering roller, a one-way baffle, a belt transmission device and a motor. Thenegative pressure unit comprises a water inlet pipeline and a vacuum pump; salvage device operation starting time, vacuum pump activation, negative pressure is formed around the collecting opening; the mixture of the sea floating waste and the water is sucked in at the same time; waste is directly taken away by the conveying belt, water is discharged out of the ship body under the pressure of thevacuum pump, auxiliary power is provided for the ship body, the sea float waste salvaging device with the double functions of negative pressure suction and conveying is simple in structure and capable of continuously operating, and sea float waste can be salvaged efficiently.

Description

technical field [0001] The invention relates to the field of sea drift waste salvage treatment, in particular to a sea drift waste salvage device with dual functions of negative pressure suction and transmission. Background technique [0002] At present, the Chinese government has paid more attention to the salvage of sea-drift waste in the offshore. While trying its best to control emissions, it has adopted various methods to salvage sea-drift waste. Among them, the most widely used sea-drift waste salvage methods are: manual salvage , Double-wing attack net fishing, double-vessel trawling fishing, belt transmission fishing, floating trawling spiral centrifugal pump fishing, etc. The manual salvage method has very low salvage efficiency due to the lack of mechanized equipment; the double-wing attack and pocket net salvage method improves the efficiency of waste salvage to a certain extent, but it has certain requirements on the carrying capacity of the hull and has limitati...

AI Technical Summary

Problems solved by technology

The manual salvage method has very low salvage efficiency due to the lack of mechanized equipment; the double-wing attack and pocket net salvage method improves the efficiency of waste salvage to a certain extent, but it has certain requirements on the carrying capacity of the hull and has limitations; Ship trawling salvage is an effective method to deal with large-scale waste floating areas, but it is very difficult to transport and change bags when the net bag is full, which reduces the salvage speed; belt drive salvage can operate continuously, and the collection efficiency is high. However, due to the limitations of its conveyor belt structure, this transmission method is not easy to collect garbage in the shape of a bottle; the floating trawl spiral centrifugal pump salvage can operate continuously without changing the mesh bag, but this method sucks waste and sea water mixture, the salvage efficiency is not very high, and now there is an urgent need to research and develop a simple and efficient sea drift waste salvage device
