Embodiment 1

[0017] The structure of the double-toothed roller oil skimmer (see the attached figure 1 ) mainly consists of five parts: a buoyancy box 1, a casing 2, an oil-absorbing surface 3, two toothed rollers 4A and 4B, and drive shafts 5A and 5B. Two buoyancy boxes 1 are symmetrically and balancedly installed on both sides of the casing 2. The buoyancy boxes are used to support all parts of the oil skimmer. The tooth outer surfaces of the gear rollers 4A and 4B are close to the oil-absorbing surface 3, and the oil-absorbing surface 3 is made of wool felt. The oil-absorbing material has a thickness of 30mm; the length of the toothed roller is 1000mm, and the diameter is 500mm; the arc surfaces on both sides of the casing 2 are attached to the outside of the oil-absorbing material at the tooth tip of the two toothed rollers to form a relative seal, and the two toothed rollers The centers of 4A and 4B are respectively connected with drive shafts 5A and 5B to form a static fit, and the dr...

Embodiment 2

[0020] The toothed roller in this embodiment is formed by superimposing a plurality of toothed columnar members. The oil-absorbing surface material on the toothed roller adopts a plurality of small strips of alloy aluminum plates stacked end to end to form a plate chain layer with a thickness of 80 mm. Fastened to the outer surface of the teeth of the toothed roller, the diameter of the toothed roller is 1500 mm, and the length is 2000 mm. The overall structure of the oil skimmer is basically the same as that of Embodiment 1.

Embodiment 3

[0022] The toothed roller of this embodiment is formed by superimposing a plurality of toothed columnar members. The oil-absorbing surface material on the toothed roller is made of a plurality of small stainless steel plates stacked end to end to form a plate chain layer with a thickness of 500 mm. Fastened to the outer surface of the teeth of the toothed roller, the diameter of the toothed roller is 4000 mm, and the length is 5000 mm. The overall structure of the oil skimmer is basically the same as that of Embodiment 1.

Abstract

A dual toothed rollers type oil collector for recovering the oil leaked on the water surface features that the mutually engaged two toothed rollers on whose surface an oil absorbing material is stuck are arranged in the casing supported by a floating box, and when said two toothed rollers are rotating, and oil-collecting space is formed above the rollers in the casing. The collected oil is delivered via pipeline to a defined position.

Description

technical field [0001] The invention relates to a special equipment used for recovering oil spill after an oil spill accident occurs on the water surface. Background technique [0002] In the process of offshore oil exploitation and ship transportation, oil spill accidents on the water surface are unavoidable. The oil skimmer is any mechanical device specially designed to recover the oil spilled on the water surface / oil-water mixture without changing its physical and chemical properties. The basic principle is to separate the oil from the water surface by using the flow characteristics of the oil / oil-water mixture, the density difference between oil and water, and the adsorption characteristics of materials for the oil / oil-water mixture. [0003] Classified from the working principle of oil spill recovery, the oil skimmers currently in use mainly include four types: weir type, vacuum type, lipophilic type and other types of mechanical devices. Weir oil skimmer refers to a d...
