Description

Technical Field

[0001] This invention relates to the field of mineral separation, and more particularly to a fluorite flotation system based on oleic acid synergist. Background Technology

[0002] Flotation involves using surfactants—foaming agents—that generate a large number of bubbles. When air is introduced into water or when agitation causes air to enter the water, the hydrophobic end of the surfactant oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming a bubble. Another type of fluorite flotation system, based on oleic acid as a synergist, uses surfactants (generally cationic surfactants, but also including aliphatic amines) that adsorb onto the surface of solid mineral powder. This adsorption exhibits selectivity depending on the mineral's properties. The basic principle is to utilize lattice defects on the crystal surface, allowing the outward-facing hydrophobic end to partially insert into the bubble. Thus, during flotation, the bubble may carry away specific mineral powder, achieving the purpose of mineral beneficiation.

[0003] Our experimental team has long been reviewing and studying a large amount of relevant records and data on mineral flotation technology. Simultaneously, relying on relevant resources and conducting numerous related experiments, we discovered existing technologies such as CN108499745B, CN112657684B, US09550191B2, and US08833562B2. For example, the existing technology discloses a flotation ore separator, flotation device, and flotation ore separator configuration method, which relates to the field of mineral processing technology. The flotation ore separator provided by this invention includes: a box body, a first valve group, and a second valve group; the box body has a first inlet, a first outlet, and a second outlet; the first valve group and the second valve group are respectively installed on the box body, the first valve group is used to control the on / off state of the first inlet and the first outlet, and the second valve group is used to control the on / off state of the first inlet and the second outlet. The flotation ore box provided by this invention can switch the slurry flow direction without interrupting the overall flotation process. It is especially suitable for connecting two flotation machines in the flotation process, and can isolate the flotation machines operating in different locations.

[0004] This invention addresses the common problems in the field, such as the inability to automatically identify, locate, and transfer the flotation foam layer in flotation operations with varying amounts of fluorite ore, the inability to effectively improve the efficiency of fluorite flotation, and the inadequate stirring of fluorite ore deposited at the bottom of the mixing tank, which in turn affects the flotation effect.

[0026] Example 1:

[0027] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 This embodiment constructs a fluorite flotation system based on oleic acid synergist;

[0028] A fluorite flotation system based on oleic acid synergist, the fluorite flotation system comprising a mixing module for receiving and mixing fluorite ore, a detection module for monitoring the formation of a foam layer within the mixing module, and a scraping module for automatically scraping off the foam layer generated within the mixing module. The mixing module includes a receiving tank for receiving the fluorite ore, a stirring unit disposed within the receiving tank for stirring the mixed slurry, an inlet for inputting the oleic acid synergist into the receiving tank, an outlet disposed on the tank wall for transferring the mixed slurry, a screw discharge device connected to the outlet, and an air inlet mechanism for inputting gas into the receiving tank. The stirring unit includes a bottom stirring mechanism disposed on the bottom wall of the receiving tank, and at least two horizontal stirring mechanisms respectively disposed at different horizontal heights within the receiving tank.

[0029] Specifically, the bottom wall of the receiving tank is a frustum structure protruding relative to the top wall of the receiving tank, with the top frustum surface of the frustum structure as the upper platform and the side surface of the frustum structure as the side platform. The bottom stirring mechanism includes a mating port disposed on the upper platform and communicating with the outside of the receiving tank, a bottom bearing ring sleeved in the mating port, a rotating shaft passing through and sleeved in the bottom bearing ring, a bottom rotary motor fixed to the outer bottom wall of the receiving tank and used to drive the rotating shaft to rotate, and at least one rotating scraper with one end connected to the outer shaft wall of the rotating shaft and at least partially attached to the side platform. When the bottom rotary motor drives the rotating shaft to rotate, the rotating scraper is driven by the rotating shaft to scrape along the side platform to prevent fluorite ore from adhering and accumulating on the side platform.

[0030] The horizontal stirring mechanism includes a communication port on the side wall of the receiving tank, a side bearing ring fitted inside the communication port, a horizontal rod that passes through the side bearing ring and extends horizontally into the receiving tank, fixed cylinders fitted on the outer walls of the horizontal rods, a plurality of vertical rods, one end of which is connected to the outer wall of the fixed cylinder and is perpendicular to the horizontal rod, a connecting rod that is perpendicular to the other end of the vertical rod, stirring blades fixed to the outer walls of the connecting rods, and a side rotary motor fixed to the outer wall of the receiving tank by a corresponding mounting seat and used to drive the horizontal rod to rotate.

[0032] This invention utilizes the combined operation of a bottom stirring mechanism and a side stirring mechanism to effectively mix the slurry, air, and oleic acid enhancer, while preventing fluorite ore in the slurry from settling on the bottom wall of the receiving tank and affecting the efficiency of fluorite flotation, thereby effectively improving the efficiency of fluorite flotation.

[0033] Example 2:

[0034] Combined with appendix Figure 1Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 In addition to the content included in the above embodiments, it also includes:

[0035] The detection module includes a transparent window disposed on the wall of the receiving tank to allow visual observation of the inside of the receiving tube; a camera device that captures images of the mixed slurry in the receiving tank through the transparent window at a preset specification; an analysis unit that receives the images captured by the camera device and further analyzes the foam layer formation of the mixed slurry in the images; and an operation control unit that further controls the scraping module to move to the target area of ​​the receiving tank to perform foam scraping operations based on the analysis and judgment of the analysis unit.

[0036] During the flotation process, the mixed slurry generates an upper foam layer and a lower solution layer. Specifically, the analysis unit achieves this through the following process steps:

[0037] S101: Receive the image captured by the camera device and use the image as an analysis image.

[0038] S102: Obtain the grayscale histogram of the analyzed image. Since the grayscale difference between the corresponding foam layer and solution layer in the mixed slurry of the analyzed image is large, the grayscale histogram is a bimodal curve function with two peaks. Further, the grayscale value corresponding to the trough between the two peaks is extracted as the distinguishing value Pathd.

[0039] S103: Mark the unit pixels with a grayscale value of Pathd in the analyzed image as marked pixels, thereby obtaining at least one closed shape composed of consecutive marked pixels in the analyzed image. The closed shape with the largest total number of unit pixels is used as the boundary liquid surface pattern between the foam layer and the solution layer. Based on the pre-set association between each image region in the analyzed image and the actual position of the receiving tank, and through the positional distribution of the boundary liquid surface pattern in the analyzed image, the minimum horizontal height of the boundary liquid surface pattern in the actual processing tank is further obtained.

[0040] S104: Based on the boundary liquid surface graphic, the graphic regions corresponding to the foam layer and solution layer in the analysis image are distinguished and marked to obtain a processed image that distinguishes the corresponding foam layer and solution layer regions, wherein P x，y Let P be the unit pixel in the x-th column and y-th row of the analyzed image. A，B F represents the set of all unit pixels in the boundary liquid surface graphic. x，y The grayscale value of the unit pixel in the x-th column and y-th row of the processed image:

[0041]

[0042] S105: In the processed image, the pixel gray level of the foam layer pattern is 0, the pixel gray level of the solution layer pattern is 255, and the pixel gray level of the boundary liquid surface pattern is 125. Further, the number of pixels with a gray level of 0 in the processed image is defined as Nu0, and the number of pixels with a gray level of 255 is defined as Nu. 255 To obtain the development parameters of the mixed slurry foam layer, deR = Nu0∶Nu 255 When the development parameters of the foam layer exceed the preset development parameter threshold, further analysis and processing of the foam layer are performed.

[0043] S106: Extract the foam layer pattern from the analysis image as the observation image, where T is the most important element. n·m Let GT(n, m) represent the unit pixel in the nth column and mth row of the observed image, where GT(n, m) is the T n·m The gray levels are used to obtain the mean gray value (grayF) of the pixels within the observed image.

[0044]

[0045] Where i∈{1, 2, 3…n}, j∈{1, 2, 3…m},

[0046] S107: Analyze each single-element point in the observed image to further obtain the foam characteristic parameter foR of the foam layer in the observed image. Specifically:

[0047] Get T n·m The level difference value Encro(n, m):

[0048] Encro(n, m) = |(P n+1，m )-(P n-1，m )|,

[0049] Get T n·m The vertical difference value Enver(n, m):

[0050] Enver(n, m) = |(P n，m+1 )-(P n，m-1 )|,

[0051] Get T n·m Standard difference value EST(n, m):

[0052]

[0053] further:

[0054] S108: Obtain the state parameter Rat of the foam layer:

[0055]

[0056] Where n·m is the total number of unit pixels in the observed image, NU is the preset reference value for the total number of unit pixels in the observed image, grayE is the preset reference gray level value for the foam layer, and ff' is the preset reference value for foam features.

[0057] S109: When Rat≤RP, it is determined that the foam layer development has reached the target scraping state, where RP is the upper limit value of the state parameter corresponding to the target foam state of the foam layer during the flotation of the mixed slurry in the receiving tank, obtained by those skilled in the art through a large number of repeated experiments.

[0058] S110: When the foam layer develops to the scraping state, the lowest horizontal height of the boundary liquid surface pattern in the actual treatment tank is taken as the working height, and the working height is further sent to the working control unit.

[0059] The present invention uses the analysis unit to effectively detect the flotation of the mixed slurry in the receiving tank, and automatically and accurately scrapes and transfers the foam layer in the receiving tank by monitoring and analyzing the foam layer in the mixed slurry, thereby effectively improving the efficiency of fluorite flotation.

[0060] Example 3: Combined with Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 In addition to the content included in the above embodiments, it also includes:

[0061] The scraping module includes a vertically arranged scraper plate for scraping the foam layer of the mixed slurry, a transfer port on the scraper plate, through-holes distributed on the top wall of the receiving tank, a transfer pipe with one end connected to the transfer port and the other end extending through the through-hole to the outside of the receiving tank, a negative pressure pump connected to the transfer pipe to generate negative pressure at the transfer port for adsorbing foam, a fixing unit connected to the outer wall of the receiving tank for adjusting and fixing the transfer pipe, a lifting drive mechanism fixedly connected to the fixing plate for driving the scraper plate to move up and down relative to the receiving tank, and a horizontal drive mechanism for driving the lifting drive mechanism to move horizontally relative to the receiving tank.

[0062] Specifically, the operation control unit receives the operation height obtained by the analysis unit, generates a drive command related to the operation height, and sends the drive command to the scraping module. Further, the lifting drive mechanism in the scraping module drives the scraper to descend to the operation height. The horizontal drive mechanism drives the scraper to move horizontally at the operation height to scrape the foam layer. The foam scraped by the scraper enters the transfer pipe from the transfer port on the scraper and is further discharged to the outside of the receiving tank, thereby realizing the precise transfer of the foam layer in the mixed slurry.

[0063] The fixing unit includes fixing components that are respectively fitted to the through-hole to fix the corresponding transfer tubes exiting the through-hole. Each fixing component includes at least two rotating wheels that are rotatably fitted to opposite sides of the through-hole via a rotating shaft, driving teeth evenly distributed on the outer wall of the rotating wheels, at least two driving gears that are rotatably fitted to the outer wall of the receiving tank via corresponding fixing seats and mesh with different driving teeth, and a reduction motor that drives the driving gears to rotate. Thus, the rotation of the rotating wheels is achieved by the rotation of the driving gears, and the length of the transfer tube inserted into the receiving tank is adjusted. The two rotating wheels in each fixing unit are configured to clamp and fit onto the outer wall of the transfer tube on opposite sides, and the transfer tube is moved relative to the through-hole by the opposite rotation of the two rotating wheels.

[0064] The lifting drive mechanism includes a fixed bracket fixed to the ground, a horizontal plate fixedly connected to the top of the fixed bracket and horizontally arranged above the receiving tank, a fixed base movably fixed to the bottom wall of the horizontal plate, a linear drive motor fixed to the fixed base by a corresponding mounting seat and vertically extending towards the receiving tank, at least two vertical rods respectively fixedly connected to the top of the fixed base, at least two horizontally arranged stabilizing plates, one end of which is fixedly connected to one of the vertical rods and the other end of which is fixedly connected to the other vertical rod, a stabilizing opening arranged in the middle of the stabilizing plate, a drive rod passing through the stabilizing opening and connected and fixedly connected to the drive end of the linear drive motor at the corresponding top, and a connecting piece that fixes the bottom of the drive rod to the scraper plate.

[0065] The horizontal drive mechanism includes at least one linear slide fixed to the bottom wall of the horizontal plate, a moving block driven by the linear slide to move horizontally linearly, and a connecting element that connects and fixes the moving block to the fixed base to realize the synchronous driving of the linear slide to drive the fixed base and the lifting drive mechanism to move horizontally linearly. When the linear slide drives the moving block to move linearly, the lifting drive mechanism is synchronously driven to move horizontally linearly, thereby driving the scraper to move horizontally in the receiving tank to scrape and transfer the foam layer of the mixed slurry.

[0066] The present invention uses the scraping module to accurately scrape and transfer foam layers at different heights in the receiving tank, thereby effectively improving the automatic adaptability to flotation processing of different quantities of fluorite ore.
