Description

Technical Field

[0001] This utility model relates to the field of oil recovery machine technology, specifically a rotary drum oil recovery machine for recovering oil spills from water surfaces. Background Technology

[0002] Oil spills on water are mainly caused by oil well contamination, oil loading and unloading pollution, ship accidents, and natural disasters. Oil spills on water form an oil film on the sea surface, hindering the photosynthesis of marine phytoplankton and the exchange of water and air, reducing the dissolved oxygen content in the water, and thus causing marine environmental pollution. This poses a serious threat to marine ecosystems and biodiversity. Traditional physical oil spill treatment methods include the containment method, oil skimmers, ship-mounted oil recovery systems, and oil spill recovery vessels. The containment method is only used to prevent the oil from spreading on the water surface and cannot achieve true oil spill recovery. Oil skimmers have disadvantages such as high water content in the recovered oil-water mixture and recovery efficiency being easily affected by the environment. Ship-mounted oil recovery systems and oil spill recovery vessels are mostly used for large-area oil spill treatment, and their flexibility and collection efficiency need to be improved. To solve the above problems, a rotary drum oil skimmer for surface oil spill recovery is needed.

[0003] Existing oil spill recovery devices suffer from problems such as high water content in the collected oil-water mixture, requiring subsequent oil-water separation, low recovery rate, limited ability to recover oil spills only in fixed water areas behind barriers, inability to recover oil spills in moving areas, poor flexibility, large size and weight, and inability to recover oil spills in shallow water areas. Therefore, there is an urgent need for a rotary drum oil recovery device for oil spill recovery on water surfaces. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a rotary drum oil recovery machine for water surface oil spill recovery, so as to solve the problems of existing water surface oil spill recovery devices, which have high water content in the collected oil-water mixture, requiring subsequent oil-water separation operations, low recovery rate, can only recover oil spills in fixed water surface areas behind fences and cannot recover oil spills in moving oil spill areas, lack of flexibility, large size and heavy weight of equipment, and cannot recover oil spills in shallow water areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary drum oil recovery machine for recovering oil spills from water surfaces, comprising a rotary drum, an oil collection trough installed on the outer wall of the rotary drum, a main oil scraper installed on the inner wall of the oil collection trough, a side oil scraper installed on the side wall of the rotary drum, a cover plate installed on the top of the oil collection trough, a tank cover installed on the outer wall of the oil collection trough, float boxes installed on both sides of the outer wall of the rotary drum, a garbage filter screen installed on the inner wall of the tank cover, an oil discharge port opened at the bottom of the oil collection trough, an oil delivery hose installed on the outer wall of the oil discharge port, and an oil pump connection port installed on the outer wall of the oil delivery hose.

[0006] Preferably, both the main scraper and the side scraper are threadedly connected to the oil collection groove, and both the main scraper and the side scraper are tightly fitted to the outer wall of the rotating drum.

[0007] Preferably, the cover plate is threaded to the lid of the container, and the garbage filter screen is symmetrically arranged with the central axis of the lid as the center.

[0008] Preferably, the oil drain port is aligned with the center of the tank cover, and the oil delivery hose is connected to the oil drain port flange.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a rotating drum, oil collection tank, main oil scraper, and side oil scraper, partially submerges the rotating drum in water. Through the rotation of the drum, the overflow oil floating on the water surface is adhered and collected, which can recover flowing oil, and is particularly suitable for recovering medium and low viscosity oil. Then, the oil adhering to the surface of the rotating drum is scraped off by the main oil scraper and side oil scraper and collected into the oil collection tank. Moreover, the collected oil contains little free water, so there is no need for subsequent oil-water separation operations, and the overflow oil collection efficiency is significantly improved.

[0010] 2. This utility model, through the design of a cover plate, a box cover, a float box, and a garbage filter, allows the device to float on the water surface, keeping the rotating drum in a semi-submerged state, facilitating the recovery of floating oil. It also ensures stable buoyancy, good wave-riding ability, and a certain degree of resistance to wind and waves, making it suitable for oil spill recovery operations in rivers, lakes, harbors, and docks. Furthermore, its lightweight design facilitates deployment and use, and its shallow draft makes it ideal for oil recovery operations in shallow water areas such as rivers and bays, enhancing its practicality.
