Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flotation column foam collection, in particular to a flotation column foam collection device. Background Technique
[0002] A flotation column is an air-injection type flotation machine without a stirring mechanism. It aerates and stirs the pulp by passing compressed air through a porous medium (aerator), thereby realizing the separation of minerals. The types of flotation columns include microbubble countercurrent flotation columns and microbubble jet flotation columns, etc. In a flotation column, the pulp is fed into the column through an upper feed pipe and evenly flows into the flotation column. Compressed air is filled into the column through a vertical air pipe in an air chamber at the lower end of the column body, and the formed fine bubbles are evenly distributed over the entire cross-section. The pulp slowly descends under the action of gravity, and the bubbles slowly rise from bottom to top, constantly meeting the useful minerals to be selected in the pulp in the column. In the convective movement, due to the action of the reagent, the minerals to be selected adhere to the surface of the rising bubbles, forming a mineralized foam layer at the upper part of the column body and overflowing into the concentrate tank, while the remaining minerals (generally gangue or non-selected minerals) are discharged from the tailing pipe at the conical bottom of the lower part of the column body.
[0003] In the prior art, when collecting the foam layer, generally, the foam overflows into the collection device by itself, and it takes a long waiting time to accumulate enough foam for collection. During this process, the production efficiency is limited, and it is necessary to wait for the foam layer to reach the height at which it can overflow. The thickness of the foam layer is unevenly set, and the adhesion force between the foams will affect the overall flow of the foam, which may cause some foams to stay inside the device and not be effectively collected.
[0004] In view of the above problems, a flotation column foam collection device is proposed to solve the above problems. Content of the Utility Model

A fixing plate 7 is fixedly connected to the rear side of the bottom of the bracket 2. A motor 8 is fixedly connected to the rear side of the fixing plate 7. An output end of the motor 8 is fixedly connected to a gear 9. The gear 9 and the rack 6 are meshed and connected. Two electric push rods 10 are fixedly connected to the bottom of the moving plate 23. Output ends of the two electric push rods 10 are fixedly connected to a scraper 11. Inclined plates 12 are fixedly connected to the left and right sides inside the flotation machine 1. Collection boxes 13 are fixedly connected to the left and right sides outside the flotation machine 1. Filter meshes 14 are slidably connected to the inside of the two collection boxes 13. Fixing components are arranged on the front and rear sides outside the collection boxes 13, and the fixing components are used for quickly disassembling the filter meshes 14.
[0032] Specifically, the flotation machine 1 is the main device for foam generation and is used in the mineral flotation process, where the foam contains the required minerals. The support plate 3 is fixedly connected to the bottom of the bracket 2 to increase the structural stability and jointly form a sliding track for the slider 5 with the fixed rod 4. The slider 5 is slidably connected to the outside of the fixed rod 4 and is fixedly connected to the moving plate 23, moving along with the movement of the rack 6. The rack 6 is fixedly connected to the top of the moving plate 23 and meshes with the gear 9. The rotation of the gear 9 causes the movement of the rack 6 and the moving plate 23. The motor 8 is fixedly connected to the rear side of the fixed plate 7, and the output end is connected to the gear 9 to provide power to drive the rotation of the gear 9. The gear 9 is fixedly connected to the output end of the motor 8 and meshes with the rack 6. The rotation of the gear 9 drives the movement of the rack 6 and the moving plate 23. The electric push rod 10 is fixedly connected to the bottom of the moving plate 23, and the output end is connected to the scraper 11, which is used to adjust the position of the scraper 11 to adapt to foam layers of different heights. The scraper 11 is fixedly connected to the output ends of the two electric push rods 10 and is used to drain the foam from the inside of the flotation machine 1 to the collection box 13. The inclined plates 12 are fixedly connected to the left and right sides inside the flotation machine 1 and may be used to guide the foam to flow towards the collection box 13. The collection box 13 is fixedly connected to the left and right sides outside the flotation machine 1, and the filter screen 14 is slidably connected inside it, which is used to collect the foam drained by the scraper 11. The filter screen 14 is slidably connected inside the collection box 13 and is used to separate the solid particles and liquid in the foam.
[0033] Referring to Figure 2 and Figure 4 , the fixing assembly includes a frame one 15. The outside of the frame one 15 is fixedly connected to the outer wall of the collection box 13. A pull rod 16 is slidably connected inside the frame one 15. A baffle 17 is fixedly connected to one side of the outside of the pull rod 16. A spring 18 is sleeved on the other side of the outside of the pull rod 16. A frame two 19 is fixedly connected to the top of the frame one 15, and a blocking block 20 is arranged inside the frame two 19.
[0034] Specifically, the first frame 15 is fixedly connected to the outer wall of the collection box 13, providing a closed sliding space for the pull rod 16 and the baffle 17 to ensure that they can move smoothly without being interfered by the outside world. The pull rod 16 is slidably connected inside the first frame 15, with a baffle 17 fixedly connected to one side and a spring 18 sleeved on the other side. The function of the pull rod 16 is to move the baffle 17 under the control of the operator, thereby releasing or fixing the filter screen 14. The baffle 17 is fixedly connected to the outer side of the pull rod 16, usually located on one side of the filter screen 14, and is used to prevent the filter screen 14 from moving during normal operation, ensuring its stable position inside the collection box 13. The spring 18 is sleeved on the other outer side of the pull rod 16, with one end fixed and the other end connected to the pull rod 16. The function of the spring 18 is to provide a restoring force. When the pull rod 16 is pulled, the spring 18 is compressed. Once the pull rod 16 is released, the elastic force of the spring 18 will make the pull rod 16 and the baffle 17 return to their original positions. The second frame 19 is fixedly connected to the top of the first frame 15, providing a sliding and positioning space for the blocking block 20. The design of the second frame 19 ensures that the blocking block 20 can slide into or out of the first frame 15 when needed to control the movement of the baffle 17. The blocking block 20 is arranged inside the second frame 19 and is used to prevent the movement of the baffle 17 at a specific moment. When the pull rod 16 is pulled, the blocking block 20 will slide into the first frame 15 to prevent the baffle 17 from continuing to move, so that the filter screen 14 can be taken out for cleaning or replacement without fixing the baffle 17.
[0035] Refer to Figure 1 - Figure 4 Four support legs 22 are fixedly connected to the periphery of the bottom of the flotation machine 1, and a drain pipe 24 is fixedly connected to the front side of the flotation machine 1. A baffle 17 is slidably connected inside the first frame 15. One end of the spring 18 is fixedly connected to the middle of the baffle 17, and the other end of the spring 18 is fixedly connected to the inner wall of the first frame 15. The outside of the blocking block 20 is slidably connected inside the second frame 19, and the bottom of the blocking block 20 is slidably connected inside the first frame 15. One end of the pull rod 16 penetrates through the collection box 13 and is inserted into the filter screen 14, and a handle 21 is fixedly connected to the side end of the pull rod 16.
[0036] Specifically, the support legs 22 are fixedly connected to the periphery of the bottom of the flotation machine 1 to provide stable support for the flotation machine 1, ensuring that the entire device remains stable during operation. The drain pipe 24 is fixedly connected to the front side of the flotation machine 1 and is used to discharge the wastewater and unnecessary liquids generated during the flotation process, ensuring that the liquid level inside the flotation machine 1 remains at an appropriate level. One end of the spring 18 is fixedly connected to the middle of the baffle 17, and the other end is fixedly connected to the inner wall of the first frame 15. The function of the spring 18 is to provide a force to keep the baffle 17 in the position of fixing the filter screen 14 without external force, ensuring the stability of the filter screen 14. The blocking block 20 is slidably connected inside the second frame 19 and also slidably connected inside the first frame 15 at the bottom. The function of the blocking block 20 is to prevent the movement of the baffle 17 when needed, so that the operator can easily take out the filter screen 14 from the collection box 13 for cleaning or replacement. One end of the pull rod 16 passes through the collection box 13 and is inserted into the filter screen 14, and the other side is fixedly connected with a handle 21. The function of the pull rod 16 is to control the movement of the baffle 17 by operating the handle 21, thereby realizing the fixation or release of the filter screen 14. The handle 21 is fixedly connected to the side end of the pull rod 16, providing an easy-to-grip part for the operator, so that the operator can control the movement of the pull rod 16 and the baffle 17 by pulling or pushing the handle 21.
[0037] Working principle: When foam needs to be collected, start the motor 8 to drive the gear 9 to rotate. Since the gear 9 and the rack 6 are meshed and connected, when the gear 9 rotates, it will drive the rack 6 to move back and forth, and at the same time drive the moving plate 23 and the slider 5 fixedly connected thereto to slide back and forth outside the fixed rod 4, thereby driving the electric push rod 10 and the scraper 11 to move back and forth. Under the action of the electric push rod 10, the position of the scraper 11 can be adjusted according to the height of the pulp liquid level. Under the action of the scraper 11, the foam layer is drained into the collection box 13. Under the action of the filter screen 14, the foam and the remaining ore are separated, and the foam can be discharged through the drain pipe outside the collection box 13. When the filter screen 14 is used for a long time, the impurities will accumulate more and more. If it is not cleaned regularly, it will cause the filter screen 14 to be blocked, thereby affecting the filtering effect of the filter screen 14. At this time, pull the pull rod 16 outwards to drive the baffle 17 to move synchronously, thereby compressing the spring 18, so that the blocking block 20 slides into the first frame 15, thereby preventing the baffle 17 from moving until the pull rod 16 is completely separated from the inside of the filter screen 14. At this time, the handle 21 can be pulled to take out the filter screen 14 from the collection box 13 for cleaning. When installation is required, put the filter screen 13 back into the collection box 13, pull the blocking block 20 out of the first frame 15. At this time, push the pull rod 16 inwards to drive the baffle 17 to move synchronously, so that the spring 18 is reset until the pull rod 16 is inserted tightly into the filter screen 14 to complete the installation.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
