Description

Technical Field

[0001] This utility model relates to an oil skimmer, and more specifically, to a float-type oil skimmer with adjustable buoyancy. Background Technology

[0002] In the process of rare earth hydrometallurgical production, no matter how the extraction and separation process is controlled, it is inevitable that a small amount or trace amount of organic phase will be carried in the wastewater. Over time, these organic phases accumulate in the wastewater collection pond and eventually form a thick layer of organic phase that floats on the water surface, affecting the wastewater treatment process and thus reducing the overall production efficiency.

[0003] The floating suction oil skimmer is used to remove oil, grease and floating matter from storage tanks, oil pans, intercepting ponds and other sewage pits; it can also be used in open water areas such as lakes, ports, ponds and lagoons, and is a weir-type oil skimmer that can be automatically adjusted.

[0004] The existing three-ball float skimmer has a fixed buoyancy of the float, and cannot adjust the height of the skimmer's inlet according to the amount of organic matter floating on the water surface. If the inlet height is too high, it is difficult to remove the organic matter on the water surface. If the inlet height is too low, more water will be drawn in when skimming the organic matter. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a simple, adjustable buoyancy float skimmer with adjustable floating height.

[0006] The technical solution of this utility model is implemented as follows: an adjustable buoyancy float-type oil skimmer includes a mounting frame, on which a plurality of floats are arranged circumferentially, and water supply and drainage components are provided on the floats; an oil suction hopper is provided at the center of the mounting frame, and the lower outlet of the oil suction hopper is connected to an external vacuum pump through a hose; a traction component is provided on the mounting frame.

[0007] In the above-mentioned adjustable buoyancy float-type skimmer, the mounting frame includes a first annular plate disposed near the lower end of the oil hopper, and a second annular plate parallel to the first annular plate disposed near the upper end of the oil hopper; both the first and second annular plates are provided with mounting notches along the axial direction to cooperate with the float.

[0008] In the above-mentioned adjustable buoyancy float-type oil skimmer, the water supply and drainage assembly includes a water inlet hole provided on the float, a water pipe connector for connecting to an external water pipe provided on the water inlet hole, and a sealing unit provided on the water pipe connector.

[0009] In the aforementioned adjustable buoyancy float skimmer, the sealing unit is a manual ball valve installed on the water pipe joint.

[0010] In the aforementioned adjustable buoyancy float skimmer, the traction assembly includes a connecting ring mounted on a mounting frame, and a towing rope is connected to the connecting ring.

[0011] After adopting the above structure, this utility model adjusts the buoyancy by adding and draining water into the float and adjusting the weight of the water supply and drainage components. This allows the oil pump inlet to be located on the liquid surface. When the organic phase in the water reaches a certain amount, it will be automatically sucked in through the oil pump inlet. The height of the oil pump inlet can be adjusted according to the amount of organic phase generated during production, ensuring the efficiency of extracting organic phase substances without extracting too much water. Attached Figure Description

[0016] See Figure 1-2 As shown, this utility model discloses an adjustable buoyancy float-type oil skimmer, comprising a mounting frame 1, on which a plurality of floats 2 are arranged circumferentially, and a water supply and drainage assembly 3 is provided on each float 2; an oil suction hopper 4 is located at the center of the mounting frame 1, and the lower outlet of the oil suction hopper 4 is connected to an external vacuum pump via a hose; a traction assembly 5 is provided on the mounting frame 1. By setting the water supply and drainage assembly to add water and drain water into the floats to adjust the weight and change the buoyancy, the inlet of the oil suction hopper is positioned on the liquid surface. When the organic phase in the water reaches a certain amount, it will be automatically sucked in through the inlet of the oil suction hopper. The height of the inlet of the oil suction hopper can be adjusted according to the amount of organic phase generated during production, ensuring the efficiency of extracting organic phase substances without extracting excessive water.

[0017] After adjusting the buoyancy to make the oil pump float in the water, the open end is matched with the organic phase material. The external vacuum pump is started to extract the organic phase material to the external equipment for collection and filtration. Then, the small amount of filtered clean water is returned to the water.

[0018] In this embodiment, the mounting frame 1 includes a first annular plate 1a disposed near the lower end of the oil hopper 4, and a second annular plate 1b parallel to the first annular plate 1a disposed near the upper end of the oil hopper 4; both the first annular plate 1a and the second annular plate 1b are provided with axial mounting notches that mate with the float 2. The mounting frame uses an annular plate design to increase contact with water during floating, thereby improving balance and preventing the oil hopper from tilting. The float is connected to the first and second annular plates using existing welding paste.

[0019] In this embodiment, preferably, the water supply and drainage assembly 3 includes a water inlet 3a disposed on the float 2, a water pipe connector 3b for connecting to an external water pipe on the water inlet 3a, and a sealing unit 3c disposed on the water pipe connector 3b. The sealing unit can employ any existing sealing technology, such as a rubber stopper seal or a valve.

[0020] Furthermore, the sealing unit 3c is preferably a manual ball valve installed on the water pipe joint 3b. Using a manual ball valve to seal the water pipe joint facilitates quick and easy opening and closing, and compared to a rubber stopper seal, it avoids the risk of rubber stopper loss.

[0021] In this embodiment, the traction component 5 includes a connecting ring 5a mounted on the mounting frame 1, and a towing rope 5b is connected to the connecting ring 5a. When the wastewater collection pool is small, the mounting frame can be moved manually using the towing rope, which is simple in structure, convenient to operate, and can effectively save costs. Furthermore, when the wastewater collection pool is large and personnel cannot reach the center of the water area, an automated mobile device, such as a drone equipped with sensors or remotely controlled, or a remotely controlled boat, can be connected to the towing rope for towing.

[0022] During use, add an appropriate amount of water to the inside of the float according to the thickness of the organic phase material floating on the water surface, so that the oil pumping bucket floats on the water surface at a suitable height. Pull it to the area with floating organic phase material by dragging the tow rope, start the external vacuum pump to draw the organic phase material into the oil pumping bucket and transport it to the outside for collection and filtration.

[0023] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
