Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, in particular to a flotation device for ore dressing. Background Art

[0002] Flotation refers to the use of surfactants - frothers that can generate a large number of bubbles. When air is introduced into the water or air enters the water due to water agitation, the hydrophobic end of the surfactant is oriented toward the air side of the bubbles at the gas-liquid interface, while the hydrophilic end remains in the solution, forming bubbles; another type of surfactant that acts as a capture agent (generally cationic surfactants, also including fatty amines) is adsorbed on the surface of the solid mineral powder.

[0003] However, the existing flotation devices for mineral processing have the following shortcomings:

[0004] When the slurry is placed in the flotation device, air is released from the bottom to the top. After being stirred by the mechanical components, the air is accelerated to mix into the slurry, and bubbles are continuously generated under the action of the activator. The solid mineral powder in the slurry is locked into the generated bubbles. Under the action of the mechanical components, the bubbles adsorbed with mineral powder continue to float toward the surface of the slurry. The existing flotation device mainly uses a scraper to continuously scrape off the bubbles on the surface of the mortar. However, the surface mortar cannot be locked during the process, which makes it easy for the scraper to scrape off the bubbles together with the mortar and mix them into the bubbles, resulting in the need for repeated processing of the resulting product. Utility Model Content

[0005] The utility model starts the pneumatic push rod, and its shaft end is slowly released, driving the pressing net to move slowly downward until the pressing net is fully pressed onto the mortar surface and the bubbles are locked in each grid. The driving motor is further started and acts on the second linkage rod to make the scraper rotate at a low speed and continuously scrape the bubbles floating to the grid surface, thereby ensuring that the scraper cannot contact the slurry, so as to solve the problems raised by the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flotation device for mineral processing, comprising a reaction box, the front surface of the reaction box is connected with a triangular interface, a group of metal brackets are fixedly installed on the top of the reaction box, a first horizontal plate is fixedly installed between the tops of a group of the metal brackets, a rectangular frame is arranged inside the reaction box, a pressure covering net is fixedly installed on the inner surface wall of the rectangular frame, a hollow sleeve is fixedly installed at the center of the pressure covering net, connecting plates are fixedly installed on both sides of the inner wall of the rectangular frame, a locking frame is fixedly installed on the top of each of the first horizontal plates, a pneumatic push rod is fixedly installed inside each of the locking frames, and the axial end of each of the pneumatic push rods is fixedly inserted in the corresponding connection plate, two joints are fixedly installed on the top of the triangular interface, a second linkage rod is movably inserted between the opposite sides of the two joints, two clamps are fixedly installed on the outer wall of the second linkage rod, and two scrapers are embedded in the two clamps, a driving motor is fixedly installed on the outer wall of one of the joints, and the output end of the driving motor is connected to one end of the outer wall of the second linkage rod.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] In the utility model, by starting the relevant driving components, the stirring fan blades are continuously driven to turn the slurry, so that the bubbles adsorbed with mineral powder can be turned to the surface of the slurry, at this time, the pneumatic push rod is turned on, and the shaft end thereof is slowly released, and the movable connection between the first linkage rod and the hollow sleeve is utilized to drive the pressing net in the rectangular frame to move slowly downward until the pressing net is fully pressed onto the mortar surface and the bubbles are locked in each grid, and the driving motor is further started and acts on the second linkage rod, so that the scraper rotates at a low speed and continuously scrapes the bubbles floating to the grid surface, the equipment adopts a mechanical transmission method, and a preset grid frame is used to press the upper slurry, and the bubbles turned to the upper layer are locked in each grid, forming a fault with the slurry surface, so that the scraper cannot directly contact the slurry when scraping the bubbles, thereby avoiding the slurry and the bubbles from mixing again.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a flotation device for mineral processing, comprising a reaction box 1, the front surface of the reaction box 1 is connected with a triangular interface 2, a group of metal brackets 3 are fixedly installed on the top of the reaction box 1, a first horizontal plate 4 is fixedly installed between the tops of the group of metal brackets 3, a rectangular frame 8 is provided inside the reaction box 1, a pressure-covering net 7 is fixedly installed on the inner surface wall of the rectangular frame 8, a hollow sleeve 28 is fixedly installed at the center of the pressure-covering net 7, connecting plates 9 are fixedly installed on both sides of the inner wall of the rectangular frame 8, and each first horizontal plate 4 is fixedly installed on the top There is a locking frame 5, and a pneumatic push rod 6 is fixedly installed inside each locking frame 5. The axial end of each pneumatic push rod 6 is fixedly inserted in the corresponding connecting plate 9. Two joints 24 are fixedly installed on the top of the triangular interface 2, and a second linkage rod 25 is movably inserted between the opposite sides of the two joints 24. Two clamps are fixedly installed on the outer wall of the second linkage rod 25, and two scrapers 26 are embedded in the two clamps. A driving motor 27 is fixedly installed on the outer wall of a joint 24, and the output end of the driving motor 27 is connected to one end of the outer wall of the second linkage rod 25.

[0022] like Figure 3 and Figure 4 As shown, a circular hole 10 is opened inside each first horizontal plate 4, and a limiting sleeve 11 is fixedly installed inside each circular hole 10. The inner shaft of each pneumatic push rod 6 is movably placed inside a corresponding limiting sleeve 11. By presetting the above components, when the pressure covering net 7 is in full contact with the mortar, the reverse force generated by the downward pressure will directly act on the axial end of the pneumatic push rod 6, causing the axial end to shake, and the limiting sleeve 11 can effectively limit the swing amplitude of the inner shaft of the pneumatic push rod 6 to prevent the inner shaft from bending and breaking.

[0023] like Figure 3 and Figure 4 As shown, a second horizontal plate 12 is fixedly installed between the tops of a group of metal brackets 3, a positioning sleeve 13 is fixedly installed on the top of the second horizontal plate 12, a first linkage rod 14 is movably inserted inside the positioning sleeve 13, and an air inlet 23 is preset inside the first linkage rod 14. By presetting the above components, when the equipment is working, the air inlet 23 is preset, and air enters from the top of the first linkage rod 14 and then flows out from its bottom, thereby determining the flow direction of air from top to bottom.

[0024] like Figure 3 and Figure 4As shown, the outer wall of the first linkage rod 14 is fixedly sleeved with an annular tray 21, a group of stirring blades 22 are embedded inside the annular tray 21, and a hollow sleeve 28 is movably sleeved on the outer wall of the first linkage rod 14. By presetting the above components and utilizing the movable connection between the hollow sleeve 28 and the first linkage rod 14, the rectangular frame 8 can freely move longitudinally inside the reaction box 1.

[0025] like Figure 3 As shown, a splicing plate 16 is fixedly mounted on the outer wall of a metal bracket 3 , a supporting bracket 17 is welded to the top of the splicing plate 16 , and a servo motor 18 is fixedly mounted on the outer wall of the supporting bracket 17 .

[0026] like Figure 3 As shown, the outer wall of the first linkage rod 14 is fixedly sleeved with a driven roller 15, the shaft end of the servo motor 18 is fixedly sleeved with a driving roller 19, and a set of traction belts 20 are movably sleeved between the outer walls of the driven roller 15 and the driving roller 19.

[0027] The effect achieved by the whole device is as follows: first, the device is moved to the designated working area, and the bottom of the reaction box 1 is fully in contact with the ground, and then the external line is connected to the power supply of the device, in order to provide energy for the multiple electrical components contained therein. When the device is working, the slurry is continuously poured into the interior of the reaction box 1 by using an external pipeline, and a quantitative activator is added. After the raw materials are fully injected into the reaction box 1, the servo motor 18 is turned on to drive the active roller 19 to rotate at a uniform speed, and the power is transmitted to the lower level by the traction belt 20, which synchronously drives the driven roller 15 and its connected parts to rotate synchronously. At this time, the slurry in the reaction box 1 begins to be stirred by the stirring blades 22 on the annular tray 21, and then air is introduced from the top of the first linkage rod 14. It is transported through the air inlet 23 and discharged from the end of the first linkage rod 14 to mix with the ore pulp. Under the action of the activator, bubbles are continuously generated, and the solid mineral powder is continuously adsorbed into the generated bubbles. As the stirring blades 22 continue to turn the ore pulp, the bubbles adsorbed with the mineral powder can be turned to the surface of the ore pulp. At this time, the pneumatic push rod 6 is turned on, and its axial end is slowly released. The movable connection between the first linkage rod 14 and the hollow sleeve 28 is utilized to drive the pressure-coating net 7 in the rectangular frame 8 to move slowly downward until the pressure-coating net 7 is fully pressed onto the mortar surface and the bubbles are locked in each grid. The drive motor 27 is further started and acts on the second linkage rod 25, so that the scraper 26 rotates at a low speed to continuously scrape the bubbles floating to the grid surface.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
