Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical copper refining technology, and in particular, to a three-phase extraction device for use in extraction processes. Background Technology

[0002] In hydrometallurgical copper smelting, copper extraction is a crucial step that connects the preceding and following processes. However, during the extraction process, a stable emulsion is usually generated at the liquid-liquid interface. The reasons for the formation of this emulsion are as follows: First, the effect of solid particles in the leaching solution; second, the oxidative degradation of the organic phase copper extractant by harmful impurities such as Fe, Mn, and Si in the leaching solution. Ultimately, this leads to the formation of a flocculent substance resembling tofu pudding at the interface between the organic and aqueous phases (referred to as the third phase).

[0003] In hydrometallurgical copper smelting plants in the Democratic Republic of Congo, the extraction system inevitably produces three-phase materials due to various factors, including solid suspended particles in the leaching solution, the conversion of some soluble impurities into precipitates or micelles during extraction, extractant degradation, and humic acid interference. If these three-phase materials accumulate in the extraction system without timely removal, they can lead to system shutdown in severe cases, necessitating timely cleaning. One method is to shut down the system to clean the three-phase materials, but this severely impacts system operation; another method is to continuously extract the three-phase materials without shutting down the system. In small extraction plants (copper extraction capacity less than 10,000 t / a), manual removal or suction using a hose pump is typically used to reduce the adverse effects of the three-phase materials on subsequent electrowinning processes. However, in large extraction plants (copper extraction capacity greater than 20,000 t / a), the extraction workshop only uses self-priming hose pumps to extract the three-phase materials, without designing dedicated equipment for this purpose, resulting in low efficiency. If the three-phase material accumulated in the extraction clarification chamber is not cleaned in time or the cleaning rate is less than the enrichment rate, some organic phase will inevitably be carried into the electrodeposition system, which will have an adverse effect on the quality of the cathode copper product.

[0004] Existing three-phase extraction devices, such as the invention patent CN201810830922.3, disclose a method for three-phase material treatment and organic phase purification in an extraction process. According to this patent, it is used in a large copper extraction system. However, this patent has the following problems: 1. The device can only move on a fixed track to extract three-phase materials; 2. During the suction process of the hose pump, there is a situation where the pump suction force is too large, which will suck up excess oil or water phase, resulting in an increased load on the subsequent processing system. Utility Model Content

[0005] This invention provides a three-phase extraction device for extraction processes, which solves the technical problems of existing devices that can only move on a fixed track, are inflexible in extracting three-phase substances, and are prone to sucking up excess oil or water phase.

[0006] According to one aspect of the present invention, a three-phase material extraction device for an extraction process is provided. The three-phase material extraction device is installed in a clarification tank and is able to move freely within the clarification tank. The three-phase material extraction device includes a height adjustment device for adjusting the height of the three-phase material. A suction hose and a water phase baffle are installed on the height adjustment device. The suction port of the suction hose is used to extend into the interface of the three-phase material. The water phase baffle is located below the suction port of the suction hose and is used to support the water phase interface. A gap for suctioning the three-phase material is provided between the suction port of the suction hose and the water phase baffle.

[0007] Furthermore, the three-phase material extraction device also includes a support base, and the height adjustment device is mounted on the support base in a height-adjustable manner.

[0008] Furthermore, at least one side of the support base is provided with a traction bracket, and a traction rope is connected to the traction bracket. The traction rope is used to drive the three-phase material extraction device to move freely in the clarification tank through the traction bracket.

[0009] Furthermore, the traction brackets are symmetrically arranged on opposite sides of the support base, and the traction brackets are inclined outward in an upward direction away from the center of the support base.

[0010] Furthermore, the height adjustment device includes a vertically arranged screw threaded to a pre-set threaded hole on the support base.

[0011] Furthermore, the height adjustment device also includes a handle, which is disposed at the top of the screw thread and is used to drive the screw thread to rotate.

[0012] Furthermore, a visual scale is fixedly installed on the screw, which is used to display the depth of the liquid entering the suction port to ensure that the position of the three-phase material is reached.

[0013] Furthermore, the outlet end of the suction hose is connected to a hose pump, and an electromagnetic flow meter is installed at the outlet end of the hose pump to adjust the three-phase material extraction rate.

[0014] Furthermore, the suction port of the suction hose is shaped like a downward-facing funnel.

[0015] Furthermore, the three-phase material extraction device is equipped with casters at the bottom.

[0016] This utility model has the following beneficial effects:

[0017] This utility model discloses a three-phase material extraction device installed within a clarification tank and capable of free movement within the tank. Under manual traction control, the device extracts three-phase materials from various areas of the clarification tank, offering greater flexibility. A height adjustment device is used to adjust the extraction based on the height of the three-phase materials, allowing for flexible application at interfaces with different heights. The suction port of the suction hose extends into the three-phase interface, maximizing the intake of three-phase materials through this port. A water phase baffle is positioned below the suction port of the suction hose and is used at the water phase interface. The water phase baffle is positioned opposite the suction port of the suction hose, preventing the intake of excessive water phase while extracting the three-phase materials, thus improving extraction efficiency and reducing the load on subsequent processing.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] See Figure 1An embodiment of the first aspect of this utility model provides a three-phase material extraction device for an extraction process. The three-phase material extraction device is installed in a clarification tank and can move freely within the clarification tank. The three-phase material extraction device includes a height adjustment device 1 for adjusting according to the height of the three-phase material. A suction hose 2 and an aqueous phase baffle 6 are installed on the height adjustment device 1. The suction port 5 of the suction hose 2 is used to extend into the interface of the three-phase material. The aqueous phase baffle 6 is located below the suction port 5 of the suction hose 2 and is used to be mounted at the aqueous phase interface. A gap for suctioning the three-phase material is provided between the suction port 5 of the suction hose 2 and the aqueous phase baffle 6.

[0028] This utility model's three-phase material extraction device is installed inside a clarification tank and can move freely within it. Under manual traction control, it can extract three-phase materials from various areas of the clarification tank, making it more flexible to use. With external traction, the three-phase material extraction device can move from 400 to 800 meters. 3 The purpose is to allow for free movement within the clarification chamber to extract the three-phase material. The suction hose 2 is made of transparent PVC and is fixed to the height adjustment device 1 by a hose clamp. Under the adjustment of the height adjustment device 1, the suction hose 2 draws in the maximum amount of the three-phase material from the three-phase compression layer through the suction port 5. The aqueous phase baffle 6 is set opposite to the suction port 5 of the suction hose 2, which can prevent the suction of too much aqueous phase while extracting the three-phase material, thereby improving the extraction efficiency of the three-phase material and reducing the load on subsequent processing.

[0029] During the absorption of the three-phase material, as the thickness of the three-phase material decreases, the thickness of the organic phase increases (since the total height of the organic phase, aqueous phase, and three-phase material is constant, in the extraction and clarification chamber, when the valve adjusting the height of the aqueous phase is fixed, the total height of the three-phase material and the organic phase is also fixed; as the three-phase material gradually decreases, the thickness of the organic phase gradually increases to fill the space freed up by the decrease in the three-phase material). At this time, the probability of the suction hose 2 drawing the aqueous phase will also gradually increase. This application sets an aqueous phase baffle 6 on the height adjustment device 1, which can reduce the amount of aqueous phase drawn and reduce the load on the subsequent three-phase material treatment. When performing the actual three-phase material extraction work, the position of the extraction device and the height of the suction hose 2 can also be moved and the height of the suction hose 2 adjusted by observing the extraction of the three-phase material in the suction hose 2 (the contents of the clarification tank from bottom to top are: ① aqueous phase: copper sulfate solution, blue; ② three-phase material: milky white; ③ organic phase: brownish black; the color and flow of the liquid in the suction hose can be observed to determine whether the three-phase material is being extracted).

[0030] This device is suitable for clarification chambers with uneven thickness of three-phase materials. It allows for precise extraction of three-phase materials through observation and manual adjustment via a visual quartz tube, and by manually adjusting the position of the three-phase material extraction device. It is suitable for small-scale scenarios or scenarios requiring more flexible control. Due to its relatively simple structure, low cost, and ease of maintenance, it is especially suitable for working conditions requiring frequent operation.

[0031] In an embodiment of this utility model, the three-phase material extraction device further includes a support base, and the height adjustment device 1 is vertically and flexibly mounted on the support base. The support base on the three-phase material extraction device supports and fixes the height adjustment device 1. The height adjustment device 1 passes through the support base and can rotate up and down relative to the support base to adjust its height, so as to adapt to the extraction conditions of three-phase materials of different thicknesses.

[0032] In an embodiment of this utility model, a traction bracket 3 is provided on at least one side of the support base, and a traction rope is connected to the traction bracket 3. The traction rope is used to drive the three-phase material extraction device to move freely in the clarification tank via the traction bracket 3. The traction bracket 3 is fixedly connected to the side of the support base to facilitate the free movement of the three-phase material extraction device. In addition, traction brackets 3 can be provided on multiple sides of the support base to improve the flexibility of the three-phase material extraction device.

[0033] In this embodiment of the invention, the traction bracket 3 is symmetrically arranged on opposite sides of the support base, and the traction bracket 3 is inclined outwards in an upward direction away from the center of the support base. The traction bracket 3 includes a first connecting rod, a second connecting rod, and a crossbar fixedly connected to the first connecting rod and the second connecting rod. The first connecting rod and the second connecting rod are respectively fixed to both ends of one side of the support base, so that the traction bracket 3 forms a quadrilateral structure. By symmetrically arranging such a traction bracket 3 on two sides of the support base and connecting a traction rope to the traction bracket 3, the three-phase material extraction device can be pulled and moved in any direction, with a high degree of flexibility and freedom.

[0034] In an embodiment of this utility model, the height adjustment device 1 includes a vertically arranged helical screw 7, which is threadedly connected to a pre-set threaded hole on the support base for adjusting the height of the helical screw 7 vertically. The threaded hole can be directly formed on the support base plate or by a nut fixed to the support base plate. In this application, the helical screw 7 is threadedly connected to the mounting plate via a nut, which not only enables height adjustment but also further improves the installation tightness of the helical screw 7, preventing tilting and wobbling during the three-phase material extraction process.

[0035] In an embodiment of this utility model, the height adjustment device 1 further includes a handle, which is disposed on the top of the screw 7 and is used to drive the screw 7 to rotate.

[0036] In this embodiment of the invention, a scale 4 is fixedly mounted on the screw 7. The scale 4 is used to display the depth of the liquid entering the suction port, ensuring that the position of the three-phase material is reached. Before extraction, the height of the three-phase material is measured through a graduated glass tube, and the height of the screw 7 is adjusted according to the obtained height data. The screw 7 is set with a scale of 0-50cm. By adjusting the screw 7 in conjunction with the PVC transparent flexible tube, the efficiency of three-phase material extraction can be accurately observed, providing higher observation accuracy and adjustment flexibility.

[0037] In this embodiment of the invention, the outlet end of the suction hose 2 is connected to a hose pump, and an electromagnetic flow meter is installed at the outlet end of the hose pump. The electromagnetic flow meter is used to adjust the three-phase material extraction rate. By adjusting the flow rate of the electromagnetic flow meter at the hose pump outlet (adjusting the three-phase material extraction rate under the precise control of the PLC), the extraction rate of the three-phase material can be roughly calculated. After multiple tests, a suitable extraction rate can be obtained. This device stabilizes the extraction of three-phase materials by adjusting the flow rate and ensures accuracy during the extraction process through the electromagnetic flow meter.

[0038] In an embodiment of this utility model, the suction port 5 of the suction hose 2 is shaped like a downward-facing funnel. By framing the suction port 5 of the suction hose 2 as a funnel, this application increases the contact area with the three-phase material, reduces local resistance, facilitates the extraction of the three-phase material, and improves suction efficiency.

[0039] In an embodiment of this invention, the three-phase material extraction device is equipped with casters at its bottom. Installing casters at the bottom of the three-phase material extraction device improves its mobility.

[0040] This application allows for flexible adjustment of the extraction range and accuracy via a traction rope and a visually calibrated pipeline. Compared to the fixed track design of existing technologies, it offers greater operational flexibility and can cover a larger area of ​​the clarification chamber. By employing an aqueous phase baffle and an electromagnetic flowmeter to control the extraction process, excessive aqueous phase ingress is avoided, improving extraction efficiency and reducing the burden of subsequent processing. This makes it suitable for the extraction needs of large-scale clarification chambers. In particular, the simplification and efficiency of this application's structure are more effective in large-area extraction systems.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
