Description

Technical Field

[0001] This utility model belongs to the field of chemical separation technology, specifically relating to a copper extractant oil-water emulsion dehydrator. Background Technology

[0002] The copper extractant oil-water emulsifier is a device specifically designed to address the oil-water emulsification problem encountered during copper extraction. In the hydrometallurgical process of copper, the copper extractant plays a crucial role, selectively extracting copper ions from copper-containing solutions.

[0003] However, during the extraction and reverse mixing processes, the oil and water phases are continuously mixed and rapidly dispersed in the mixer, followed by phase separation. During this process, a small amount of oil and water emulsifies to form tiny water-in-oil droplets. These droplets are then transported with the extractant to the reverse mixing unit for further continuous mixing, rapid dispersion, and phase separation. During the transfer of the extractant between acidic and alkaline solutions, acidic and alkaline droplets are continuously entrained into the other liquid phase, resulting in acid-base neutralization reactions. Therefore, it is necessary to continuously add new reagents to adjust the pH value, which increases material and labor waste and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a copper extractant oil-water emulsion dehydrator to solve the problem mentioned in the background art, which requires the continuous addition of new reagents to adjust the pH value, thus increasing material waste and reducing production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper extractant oil-water emulsification dehydrator, comprising a water tank and an oil inlet installed inside the outer wall of the right end of the water tank;

[0006] An oil drain port is provided on the outer wall of the left end of the water tank near the lower side;

[0007] A baffle plate is provided on the lower inner wall of the water tank;

[0008] The baffle plate is equipped with an overflow pipe inside;

[0009] The lower inner wall of the water tank is fixedly connected with filter screen a, filter screen b and filter screen c from left to right.

[0010] Preferably, the surface of the filter screen a is coated with a Teflon coating.

[0011] Preferably, the vertical lengths of filter screens a, b, and c are all less than the vertical length of the water tank.

[0012] Preferably, filter a has a mesh size of 200, filter b has a mesh size of 180, and filter c has a mesh size of 150.

[0013] Preferably, filter screens a, b, and c are all made of stainless steel.

[0014] Preferably, the overflow pipe is internally threaded with an adjusting pipe to adjust the water level at the inlet of the overflow pipe.

[0015] Preferably, the upper outer wall of the water tank is provided with an inspection cover, and each of the four corners of the upper outer wall of the inspection cover is provided with a fastening screw that engages with the water tank to restrict the position of the inspection cover.

[0016] Preferably, an observation window is embedded inside the front outer wall of the water tank to observe the water level inside the tank, and a drain valve is screwed into the lower outer wall of the water tank.

[0017] Compared with the prior art, this utility model provides a copper extractant oil-water emulsification dehydrator, which has the following beneficial effects:

[0018] By installing filters a, b, and c, the oil-phase extractant passes through multiple layers of high-density stainless steel filters. The larger water droplets in the oil-in-water mixture are blocked, continuously aggregating, colliding, merging, and growing larger, achieving secondary oil-water phase separation. The oil phase floats to the top, while the water phase sinks. A small number of tiny water droplets in the oil-in-water mixture reach the high-density Teflon filter and are blocked again, continuously aggregating, colliding, merging, and growing larger. The oil phase is then blocked by the water phase, achieving tertiary oil-water phase separation. The oil phase floats to the top, while the water phase sinks. The different levels of filters sequentially block the water droplets, greatly increasing the probability of droplet aggregation and growth, significantly improving the efficiency of oil-water separation. The multi-layered filters and multiple... The phase separation design achieves more thorough oil-water separation. From the interception of larger water droplets in oil by a high-density stainless steel filter, to the further processing of tiny water droplets in oil by a high-density Teflon filter, almost all water in the oil phase can be separated. Even extremely small water droplets can be separated into larger droplets after multiple interceptions and fusions through multiple layers of filters. This results in an oil phase extractant with extremely low water content, meeting the stringent purity requirements of the subsequent copper extraction process. At the same time, it can also intercept some solid impurities in the oil phase extractant, improving the quality of the oil phase extractant and laying the foundation for improving the purity of the final copper product.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 The copper extractant oil-water emulsion dehydrator shown includes a water tank 3 and an oil inlet 11 installed inside the outer wall of the right end of the water tank 3.

[0026] An oil drain port 4 is provided on the outer wall of the left end of water tank 3 near the lower side;

[0027] A baffle plate 6 is provided on the lower inner wall of the water tank 3;

[0028] An overflow pipe 12 is installed inside the baffle plate 6;

[0029] The lower inner wall of the water tank 3 is fixedly connected with filter screens a7, b9, and c10 from left to right. By opening the valve connecting the oil inlet 11 to the outside, the oil-water emulsion containing copper extractant is slowly introduced into the water tank 3. After entering the water tank 3, the oil-water emulsion begins to separate under the action of gravity. The water phase gradually settles to the bottom of the water tank, while the oil phase floats upward. During the upward movement of the oil phase, it passes through filter screens c10, b9, and a7 in sequence to achieve secondary phase separation of oil and water. Upon contact with the high-density Teflon filter screen a7, the oil phase will pass through this filter screen to achieve tertiary phase separation. The oil phase after the third phase separation enters the left side of the baffle plate 6 through the adjustable overflow pipe 12 and is finally discharged outward from the oil outlet 4.

[0030] like Figure 2 and Figure 4 As shown, the surface of filter a7 is coated with Teflon. The vertical lengths of filter a7, filter b9, and filter c10 are all less than the vertical length of water tank 3. Filter a7 is 200 mesh, filter b9 is 180 mesh, and filter c10 is 150 mesh. Filter a7, filter b9, and filter c10 are all made of stainless steel.

[0031] As the first layer of filter, filter c10, with its relatively large pore size, can initially intercept larger water droplets in the oil, causing these droplets to gather, collide, and merge on the filter surface. The remaining relatively smaller water droplets in the oil after initial treatment by filter c10 are further intercepted by filter b9. Filter b9, with a smaller pore size than filter c10, can capture even smaller water droplets, further promoting their aggregation and fusion. Finally, the oil treated by the first two layers of filters reaches filter a7. Filter a7, with its even smaller pore size, intercepts even smaller water droplets, achieving deep separation of water from the oil. The Teflon material has low surface energy, making it less likely for water droplets to adhere to filter a7 upon contact; instead, they tend to roll and gather on the filter surface.

[0032] like Figure 3 As shown, an adjusting pipe 13 is screwed into the inside of the overflow pipe 12 to adjust the water level of the inlet water in the overflow pipe 12.

[0033] When the regulating tube 13 is rotated clockwise, it moves upward, increasing the height of the effective inlet. When the regulating tube 13 is rotated counterclockwise, it moves downward, lowering the height of the effective inlet. By adjusting the regulating tube 13, the discharge rate of the oil phase and the water level are controlled, ensuring the stable operation of the oil-water separation process.

[0034] like Figure 1 As shown, an inspection cover 1 is provided on the upper outer wall of the water tank 3. At the four corners of the upper outer wall of the inspection cover 1, there are fastening screws 2 that are screwed into the water tank 3 to restrict the position of the inspection cover 1.

[0035] When it is necessary to inspect, repair or replace the filters a7, b9 and c10, baffle 6, overflow pipe 12 and other components inside the water tank, unscrew the fastening screw 2 to open the inspection cover 1, which will allow the operator to enter the water tank for operation.

[0036] like Figure 1 and Figure 2 As shown, an observation window 5 is embedded inside the front outer wall of the water tank 3 to observe the water level inside the water tank 3, and a drain valve 8 is screwed into the lower outer wall of the water tank 3.

[0037] The observation window 5 embedded inside the outer wall of the front end of the water tank 3 allows the operator to directly observe the water level inside the water tank 3. By observing the water level, the operator can judge the progress of oil-water separation and whether the water phase is accumulating and being discharged normally. The drain valve 8 screwed inside the outer wall at the lower end of the water tank 3 is used to quickly discharge the water phase remaining at the bottom of the water tank when the equipment is being cleaned or emptied. After the oil-water separation work is completed, opening the drain valve 8 can completely empty the remaining water phase in the water tank, facilitating subsequent cleaning and maintenance work.

[0038] The implementation principle of this embodiment is as follows: Open the valve connecting the oil inlet 11 to the outside, and slowly introduce the oil-water emulsion containing copper extractant into the water tank 3. After the oil-water emulsion enters the water tank 3, it begins to separate under the action of gravity. The water phase gradually settles to the bottom of the water tank, and the oil phase floats upward. During the upward movement of the oil phase, it passes through the filter screen c10, filter screen b9 and filter screen a7 in sequence to achieve secondary phase separation of oil and water. When it comes into contact with the high-density Teflon filter screen a7, the oil phase will pass through the filter screen to achieve tertiary phase separation. The oil phase after the third phase separation enters the left side of the baffle plate 6 through the adjustable overflow pipe 12, and finally is discharged outward from the oil outlet 4.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
