[0002] Currently, nickel extraction is generally achieved through a wet nickel smelting production process. In existing solutions, the flocculant addition process generally utilizes a CCD reverse washing process. However, in the specific production process, the production cost accounts for a large proportion due to the unsatisfactory mixing of the flocculant and the slurry. In order to effectively reduce the production cost, it is generally solved by reducing the flocculant consumption. However, reducing the flocculant consumption makes it difficult to ensure the mixing ratio and mixing effect of the flocculant and the slurry.

[0003] Therefore, it is necessary to design a quantitative analysis scheme to estimate the input of flocculant based on the input of slurry, so as to ensure the best matching effect, reduce the consumption of flocculant and ensure the mixing reaction effect of flocculant and slurry.

[0026] The present application provides a method, device, electronic device and storage medium for determining a flocculant filling point, which are described below respectively.

[0027] Figure 1 This is a flow chart of an embodiment of the method for determining the flocculant filling point provided in this application, as shown in FIG. Figure 1 As shown in the figure, the method for determining the flocculant filling point includes: S101. Determine the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port at different slurry initial velocities, and perform curve fitting to obtain a first mapping relationship between the slurry initial velocity and the depth of the flocculant feed pipe extending into the thickener, and a second mapping relationship between the slurry initial velocity and the distance between the flocculant feed pipe and the slurry feed port; Determine the depth of the flocculant feed pipe inserted into the thickener and the distance between the flocculant feed pipe and the slurry feed port at different slurry concentrations, and perform curve fitting to obtain a third mapping relationship between the slurry concentration and the depth of the flocculant feed pipe inserted into the thickener, and a fourth mapping relationship between the slurry concentration and the distance between the flocculant feed pipe and the slurry feed port; A flocculant filling point is determined based on the first mapping relationship, the second mapping relationship, the third mapping relationship, and the fourth mapping relationship.

[0028] It should be noted that, when executing the embodiments of the present application, it is necessary to conduct a single variable experimental analysis under different slurry initial velocities and slurry concentrations. Through the accumulation of big data, a curve fitting analysis is performed on the nonlinear functional relationship between the collected slurry initial velocity and the depth value of the flocculant feed pipe extending into the thickener, as well as the distance value between the flocculant feed pipe and the slurry feed port, so as to analyze the intrinsic correlation between each other from a quantitative perspective. At the same time, a similar scheme is adopted to also perform a curve fitting analysis on the nonlinear functional relationship between the collected slurry concentration and the depth value of the flocculant feed pipe extending into the thickener, as well as the distance value between the flocculant feed pipe and the slurry feed port, so as to analyze the intrinsic correlation between each other from a quantitative perspective. Finally, after analyzing the intrinsic correlation, under the actual slurry initial velocity and slurry concentration, the above-mentioned depth value and distance value can be determined according to these mapping relationships, thereby achieving precise positioning, which is equivalent to achieving the positioning of the flocculant filling point.

[0029] It should be noted that the first mapping relationship, the second mapping relationship, the third mapping relationship and the fourth mapping relationship are all dimensionless mapping relationships.

[0030] Compared with the prior art, the method provided by the present application first determines the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port at different slurry initial velocities and different slurry concentrations, then performs curve fitting to obtain corresponding mapping relationships, and finally determines the flocculant filling point based on the mapping relationship. The present application uses experimental means to determine the depth and distance of the flocculant feed pipe extending into the thickener under the condition of quantitative analysis of the slurry initial velocity and slurry concentration, analyzes its inherent correlation by curve fitting, and finally determines the filling point at different concentrations and different feed speeds by correlation calculation, thereby achieving sufficient mixing of the slurry and flocculant while also improving efficiency.

[0031] In some embodiments of the present application, the flocculant feeding pipe includes a first flocculation pipe, a second flocculation pipe and a third flocculation pipe at a triangular point. Specifically, a three-point addition method is generally adopted, such as Figure 2 As shown, starting from the point where the underflow and overflow of the forced dilution pump outlet mix, the three flocculation tubes are added according to a distribution of triangular points within the central cylinder circle, and the depths of insertion of the three different flocculation tubes into the mixed liquid are gradually decreasing. Generally speaking, the flocculation tube inserted at the forced dilution pump outlet is: the first flocculation tube. The upper edge of the first flocculation tube is downward to a first depth, which allows the flocculant to mix with a large amount of material. The first depth is preferably 15 cm. When inserting the second flocculation tube, it is necessary to appropriately reduce the insertion depth. The second flocculation tube is inserted a certain distance shorter than the first flocculation tube, and this distance is preferably 10 cm. The third flocculation tube is inserted a certain distance shorter than the second flocculation tube, and this distance is preferably 5 cm.

[0032] It should be noted that the principle behind the triangular arrangement of the first, second, and third flocculation tubes is that after the first flocculation tube is added, the slurry begins to flocculate and settle. Under the action of thrust, the slurry mixes with the flocculant and rotates within the stabilizing tube. After flocculation, large particles rotate and sink, while relatively small particles continue to rotate within the stabilizing tube due to the thrust. During this rotation, the sinking of heavy particles creates an upward buoyancy force for the slurry. When the weight of the small particles is less than their buoyancy, they float upward. The second flocculation tube, then added at the second point, can then further add flocculant to mix and flocculate, causing the fine particles to flocculate and sink due to gravity. Finally, the third flocculation tube, added at the third point, further flocculates the remaining very fine particles, further flocculating them and causing them to sink due to gravity. Therefore, the design of the three flocculation tubes at different points allows slurry to be flocculated at different particle sizes, accelerating flocculation efficiency while also saving flocculant usage.

[0033] In the embodiment of the present application, determining the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port at different slurry initial velocities includes: Determining a first depth value of the first flocculation tube extending into the thickener, a second depth value of the second flocculation tube extending into the thickener, and a third depth value of the third flocculation tube extending into the thickener at different slurry initial velocities; A first distance value between the first flocculation tube and the slurry feed port, a second distance value between the second flocculation tube and the slurry feed port, and a third distance value between the third flocculation tube and the slurry feed port are determined at different slurry initial velocities.

[0034] As a preferred embodiment, the first depth value is greater than the second depth value, and the second depth value is greater than the third depth value.

[0035] In an embodiment of the present application, the curve fitting to obtain a first mapping relationship between the initial velocity of the slurry and the depth of the flocculant feed pipe extending into the thickener includes: According to the initial velocity of the slurry, the first depth value, the second depth value, and the third depth value, curve fitting is performed based on the B-spline curve fitting method to obtain an expression for the first mapping relationship; The expression of the first mapping relationship is:

[0036] in, represents the initial velocity of the slurry, represents the first depth value, represents the second depth value, Indicates the third depth value, 、 、 、 、 、 、 、 represents the fitting parameters, which are all constants.

[0037] It should be noted that, through experimental demonstration and curve fitting analysis, the following conclusions can be verified: there is a nonlinear relationship between the initial velocity of the slurry and the depth of the flocculant feed pipe inserted into the thickener, which is positively correlated, and the correlation (degree of influence) between the initial velocity of the slurry and the first depth value is greater than the correlation between the initial velocity of the slurry and the second depth value, while the correlation between the initial velocity of the slurry and the second depth value is slightly greater than the correlation between the initial velocity of the slurry and the third depth value.

[0038] It is understandable that the fitting parameters 、 、 、 、 、 、 、 These are constants calculated based on geometric points such as intersection points and tangent points in the curve during the curve fitting process. In the actual implementation process, these constants can be fine-tuned.

[0039] In an embodiment of the present application, the curve fitting to obtain a second mapping relationship between the initial velocity of the slurry and the distance between the flocculant feed pipe and the slurry feed port includes: According to the initial velocity of the slurry, the first distance value, the second distance value, and the third distance value, curve fitting is performed based on a B-spline curve fitting method to obtain an expression for the second mapping relationship; The expression of the second mapping relationship is:

[0040] in, represents the initial velocity of the slurry, represents the first distance value, represents the second distance value, represents the third distance value, 、 、 Respectively represent the horizontal angles between the first flocculation tube, the second flocculation tube, and the third flocculation tube and the slurry feed port, 、 、 、 、 、 、 、 、 represents the fitting parameters, which are all constants.

[0041] It should be noted that, through experimental demonstration and curve fitting analysis, the following conclusions can be verified: the initial velocity of the slurry and the distance between the flocculant feed pipe and the slurry feed port have an inversely correlated nonlinear relationship, and the correlation (degree of influence) between the initial velocity of the slurry and the first distance value, the correlation between the initial velocity of the slurry and the second distance value, and the correlation between the initial velocity of the slurry and the third distance value are not much different.

[0042] It should also be noted that the angles between the first flocculation tube, the second flocculation tube and the third flocculation tube and the slurry feed port in the horizontal direction are 、 、 This is an influencing factor discovered during the experiment. Under different initial slurry velocities, when the angle between the slurry outlet and the lowest end of the flocculant feed pipe is different, it has a certain impact on the mixing effect of the slurry and flocculant. In specific implementations, the first distance value is generally greater than the second and third distance values.

[0043] It is understandable that the fitting parameters 、 、 、 、 、 、 、 、 These are constants calculated based on geometric points such as intersection points and tangent points in the curve during the curve fitting process. In the actual implementation process, these constants can be fine-tuned.

[0044] In the embodiment of the present application, determining the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port at different slurry concentrations includes: Determining a fourth depth value of the first flocculation tube extending into the thickener, a fifth depth value of the second flocculation tube extending into the thickener, and a sixth depth value of the third flocculation tube extending into the thickener at different slurry concentrations; The fourth distance value between the first flocculation tube and the slurry feed port, the fifth distance value between the second flocculation tube and the slurry feed port, and the sixth distance value between the third flocculation tube and the slurry feed port are determined at different slurry concentrations.

[0045] In an embodiment of the present application, curve fitting is performed to obtain a third mapping relationship between slurry concentration and the depth of the flocculant feed pipe extending into the thickener, including: According to the slurry concentration, the fourth depth value, the fifth depth value, and the sixth depth value, curve fitting is performed based on the least squares method to obtain an expression for the third mapping relationship; The expression of the third mapping relationship is:

[0046] in, Indicates the slurry concentration, represents the fourth depth value, represents the fifth depth value, represents the sixth depth value, 、 、 、 、 、 、 、 represents the fitting parameters, which are all constants.

[0047] It should be noted that, through experimental demonstration and curve fitting analysis, the following conclusions can be verified: there is a nonlinear relationship between the slurry concentration and the depth of the flocculant feed pipe inserted into the thickener, which is positively correlated, and the correlation (degree of influence) between the slurry concentration and the fourth depth value is smaller than the correlation between the slurry concentration and the fifth depth value, while the correlation between the slurry concentration and the fifth depth value is slightly greater than the correlation between the slurry initial velocity and the sixth depth value.

[0048] It is understandable that the fitting parameters 、 、 、 、 、 、 、 These are constants calculated based on geometric points such as intersection points and tangent points in the curve during the curve fitting process. In the actual implementation process, these constants can be fine-tuned.

[0049] In some embodiments of the present application, curve fitting is performed to obtain a fourth mapping relationship between the slurry concentration and the distance between the flocculant feed pipe and the slurry feed port, including: Performing curve fitting based on the least squares method according to the slurry concentration, the fourth distance value, the fifth distance value, and the sixth distance value to obtain an expression for the fourth mapping relationship; The expression of the fourth mapping relationship is:

[0050] in, Indicates the slurry concentration, represents the fourth depth value, represents the fifth depth value, represents the sixth depth value, 、 、 、 、 、 、 、 represents the fitting parameters, which are all constants.

[0051] It should be noted that, through experimental demonstration and curve fitting analysis, the following conclusions can be verified: there is a nonlinear relationship between the slurry concentration and the distance between the flocculant feed pipe and the slurry feed port, which is positively correlated, and the correlation (degree of influence) between the slurry concentration and the fourth distance value is greater than the correlation between the slurry concentration and the fifth distance value, while the correlation between the slurry concentration and the fourth depth value is slightly smaller than the correlation between the slurry initial velocity and the sixth distance value.

[0052] It is understandable that the fitting parameters 、 、 、 、 、 、 、 These are constants calculated based on geometric points such as intersection points and tangent points in the curve during the curve fitting process. In the actual implementation process, these constants can be fine-tuned.

[0053] In some embodiments of the present application, determining the flocculant filling point based on the first mapping relationship, the second mapping relationship, the third mapping relationship, and the fourth mapping relationship includes: Based on the influence relationship between the initial slurry velocity and the slurry concentration on the degree of mixing between the slurry and the flocculant, a weight distribution ratio of the initial slurry velocity and the slurry concentration under the first mapping relationship and the second mapping relationship is established, and the flocculant injection distribution relationship is determined according to the first mapping relationship, the second mapping relationship and the weight distribution ratio; The actual initial slurry velocity and slurry concentration are obtained, and based on the injection distribution relationship, the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port are adjusted.

[0054] Specifically, the flocculant injection distribution relationship is expressed by the following formula:

[0055] Where S represents the flocculant filling point, which is a two-dimensional data used to characterize the depth of the flocculant feed pipe extending into the thickener and the distance between the flocculant feed pipe and the slurry feed port. 、 represent the weight distribution ratio of the initial slurry velocity and slurry concentration respectively.

[0056] It should be noted that the formula for the flocculant injection distribution relationship is a dimensionless mapping relationship.

[0057] It is understandable that when the depth values ​​determined by the first mapping relationship and the third mapping relationship may differ, then in the case of a difference, the weight distribution ratio is used to make fine adjustments to achieve a more reasonable depth. Similarly, when the distance values ​​determined by the second mapping relationship and the fourth mapping relationship may differ, then in the case of a difference, the weight distribution ratio is used to make fine adjustments to achieve a more reasonable depth. It is necessary to explain here that the depth values ​​determined by the first mapping relationship and the third mapping relationship will have a small difference, which has been related to experimental analysis and demonstration during the quantitative analysis. Similarly, the distance values ​​determined by the second mapping relationship and the fourth mapping relationship will also have a small difference.

[0058] In summary, the method for determining the flocculant filling point provided in the embodiment of the present application determines the depth and distance of the flocculant feed pipe extending into the thickener by experimental means when the initial velocity and slurry concentration are quantitatively analyzed respectively, and analyzes its internal correlation by curve fitting. Finally, the filling point conditions at different concentrations and different feed rates are determined by correlation calculation, thereby achieving sufficient mixing of the slurry and flocculant while also improving efficiency.
