Description

Technical Field

[0001] This utility model relates to the technical field of flotation machines, and in particular to a flotation machine that is easy to add reagents to. Background Technology

[0002] In mineral flotation processes, reagents, including collectors, frothers, and modifiers, are core elements for achieving efficient mineral separation. The timeliness, uniformity, and precision of their addition directly affect flotation indicators and production efficiency. Different minerals exhibit significant differences in flotation characteristics, requiring flexible adjustments to reagent dosage and timing based on pulp conditions during production. Therefore, to optimize reagent addition, enhance the overall efficiency and flexibility of mineral processing, and meet the process's demands for efficient and convenient reagent dosing, a flotation machine with easy reagent dosing is needed to facilitate stable and efficient flotation operations. Thus, a flotation machine with easy reagent dosing is particularly needed.

[0003] However, existing flotation machines have several drawbacks during operation. The traditional flotation machine has a complex reagent dosing structure design, making it difficult to achieve quantitative and uniform dosing by manual dosing. If electric dosing is used, it relies on additional power and an electrical control system, which not only increases the difficulty of operation but also increases the equipment maintenance cost. On the other hand, the mixing of reagents and slurry often relies on simple stirring or natural diffusion, and the dosing point design of some models is unreasonable, which leads to the reagents not being able to quickly and fully mix with the slurry, affecting the flotation reaction efficiency.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN222152423U that discloses a flotation machine with a reagent dosing function. The patent states that "the beneficial effects of this utility model are: by setting up a reagent dosing component, the entire dosing component is independent of the flotation machine body, thus improving the flexibility of equipment assembly. There is no need to arrange reagent dosing pipes and related dosing equipment on the flotation machine body, greatly reducing the difficulty of equipment assembly, and also facilitating later inspection and maintenance by users." While this device achieves gravity-impact premixing of raw materials and reagents before flotation, and the independent dosing component facilitates assembly and maintenance... While it possesses protective functions, its dosing relies on additional power equipment such as dosing metering pumps, lacking a simple, purely mechanical method for quantity control, resulting in high operation and maintenance costs. The mixing of reagents and raw materials only occurs in the mixing drum before flotation, without being combined with the dynamic stirring process of the slurry in the flotation cell. It cannot replenish or adjust reagents in real time or dynamically during the flotation reaction, leading to poor adaptability to the flotation process. The mixing relies on gravity impact, and the mixing effect is greatly affected by the fluidity of the raw materials and reagents, as well as the structural dimensions of the mixing hopper. For some viscous or easily agglomerated reagents and raw materials, uneven mixing or material accumulation clogging of the leak holes and overflow holes can easily occur, resulting in insufficient stability.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide a flotation machine that facilitates reagent dosing, thereby addressing the problems mentioned in the background section regarding existing flotation machines. In operation, traditional flotation machines have complex reagent dosing structures, making it difficult to achieve quantitative and uniform dosing with manual dosing. Electric dosing relies on additional power and an electronic control system, increasing both operational difficulty and equipment maintenance costs. Furthermore, the mixing of reagents and slurry often relies on simple stirring or natural diffusion, and some models have poorly designed dosing points, resulting in reagents failing to quickly and fully integrate with the slurry, thus affecting flotation reaction efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flotation machine for easy dosing of chemicals, comprising a flotation tank, a dosing pipe on one side of the flotation tank, an air supply pipe on the other side of the flotation tank, a connecting pipe fixedly connected to one end of the air supply pipe, a first drive motor fixedly connected to one end of the flotation tank, a first transmission shaft fixedly connected to the output end of the first drive motor, an impeller fixedly connected to one side of the surface of the first transmission shaft, a fixing plate fixedly connected to one end of the connecting pipe, a chemical storage tank fixedly connected to one end of the dosing pipe, a sliding groove provided on one side of the inner wall surface of the chemical storage tank, a sliding plate slidably connected to the surface of the sliding groove, a lead screw threadedly connected to one side of the sliding plate, and a one-way valve provided on one side of the inner wall surface of the dosing pipe.

[0008] Preferably, a second drive motor is fixedly connected to one side of the flotation box, a second transmission shaft is fixedly connected to the output end of the second drive motor, and a discharge blade is fixedly connected to one side of the surface of the second transmission shaft.

[0009] Preferably, one end of the surface of the fixing plate is provided with a through hole, and the impeller is spiral in shape.

[0010] Preferably, the dosing tube is inclined, and one end of the dosing tube is located above the edge of the impeller.

[0011] Preferably, the first drive shaft is connected to the flotation box bearing.

[0012] Preferably, the lead screw is connected to the dosing tube bearing.

[0013] Preferably, the second drive shaft is connected to the flotation box bearing.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This flotation machine, which facilitates reagent addition, utilizes a purely mechanical reagent addition structure driven by a screw-driven sliding plate. It eliminates the need for additional power and electrical control systems. This allows for precise manual control of the sliding plate displacement to achieve quantitative reagent addition, reducing operational difficulty and maintenance costs. Furthermore, the combination of the inclined reagent addition pipe and the negative pressure zone at the impeller edge directly delivers the reagent to the core area of ​​the dynamic mixing of the slurry. This allows the reagent to quickly and fully integrate into the slurry under the dual effects of gravity delivery and negative pressure adsorption, significantly improving the mixing efficiency between the reagent and the slurry. Simultaneously, the independent design of the reagent storage tank and the reagent addition pipe facilitates timely reagent addition, and the connection between the reagent addition components and the main body of the flotation tank is simple, allowing for maintenance without complex operations. This effectively ensures the continuity and convenience of flotation operations and greatly improves the efficiency of the flotation reaction. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5This utility model provides a technical solution: a flotation machine for easy dosing of reagents, including a flotation tank 1, a dosing pipe 2 on one side of the flotation tank 1, an air supply pipe 3 on the other side of the flotation tank 1, a connecting pipe 4 fixedly connected to one end of the air supply pipe 3, a first drive motor 5 fixedly connected to one end of the flotation tank 1, a first transmission shaft 6 fixedly connected to the output end of the first drive motor 5, an impeller 7 fixedly connected to one side of the surface of the first transmission shaft 6, a fixing plate 8 fixedly connected to one end of the connecting pipe 4, a reagent storage tank 12 fixedly connected to one end of the dosing pipe 2, a sliding groove 13 opened on one side of the inner wall surface of the reagent storage tank 12, a sliding plate 14 slidably connected to the surface of the sliding groove 13, a lead screw 15 threadedly connected to one side of the sliding plate 14, and a one-way valve 16 provided on one side of the inner wall surface of the dosing pipe 2. During use, an appropriate amount of liquid reagent is first added to the reagent storage tank 12, and then the handle of the lead screw 15 is manually turned. Because the lead screw 15 is threadedly connected to the sliding plate 14 and the sliding plate 14... The sliding plate 14 moves closer to the dosing pipe 2 as the lead screw 15 rotates along the sliding groove 13 on the inner wall of the storage tank 12, thereby squeezing the reagent in the storage tank 12. Under pressure, the reagent pushes open the one-way valve 16 on the inner wall of the dosing pipe 2 and flows into the flotation tank 1 along the dosing pipe 2. At the same time, the first drive motor 5 is started, and its output end drives the first transmission shaft 6 to rotate, which in turn causes the spiral impeller 7 fixed on the surface of the first transmission shaft 6 to rotate. An external air source delivers air to the connecting pipe 4 through the air supply pipe 3, and then enters the flotation tank 1 through the through hole on the surface of the fixed plate 8. The air is broken into tiny bubbles by the rotation of the impeller 7 and is fully mixed with the reagent and slurry.

[0023] Furthermore, a second drive motor 9 is fixedly connected to one side of the flotation box 1, and a second transmission shaft 10 is fixedly connected to the output end of the second drive motor 9. A discharge blade 11 is fixedly connected to one side of the surface of the second transmission shaft 10. During use, when the slurry in the flotation box 1 has completed the flotation operation, the second drive motor 9 is started, and its output end drives the second transmission shaft 10 to rotate, causing the discharge blade 11 fixed to the surface of the second transmission shaft 10 to rotate accordingly. During the rotation, the discharge blade 11 pushes the slurry in the flotation box 1 to move towards the discharge port, so as to realize the orderly discharge of the slurry after flotation.

[0024] Furthermore, a through hole is provided at one end of the surface of the fixed plate 8, and the impeller 7 is spiral in shape. The through hole at one end of the surface of the fixed plate 8 allows the air transported by the connecting pipe 4 to be dispersed into multiple streams and enter the flotation box 1 evenly, avoiding concentrated air impact on the slurry. At the same time, it facilitates the impeller 7 to fully break up the air, improving the efficiency and uniformity of bubble generation. The spiral impeller 7 generates stronger axial and radial thrust when it rotates, which can drive the slurry in the flotation box 1 to roll up and down and form a circulating flow, enhancing the mixing effect of reagents and slurry. It can also more efficiently shear the air into microbubbles, increasing the contact probability between bubbles and mineral particles.

[0025] Furthermore, the dosing pipe 2 is set at an angle, with one end of the dosing pipe 2 located above the edge of the impeller 7. By setting the dosing pipe 2 at an angle, gravity is used to assist the flow of reagents, reducing the retention of reagents in the pipe and lowering the risk of blockage. At the same time, it allows the reagents to enter the flotation box 1 at a more reasonable angle, facilitating rapid integration into the slurry. With the dosing pipe 2 and the impeller 7 positioned so that one end of the dosing pipe 2 is above the edge of the impeller 7, the reagents can directly enter the negative pressure zone formed by the rotation of the impeller 7. Under the dual action of "gravity pressure delivery + negative pressure suction", it is ensured that the reagents enter stably and are immediately dispersed by the slurry flow driven by the impeller 7, avoiding waste caused by the reagents floating on the surface of the slurry and improving the utilization rate of the reagents.

[0026] Furthermore, the first drive shaft 6 is connected to the flotation box 1 by a bearing. Through the arrangement of the first drive shaft 6 and the flotation box 1, the bearing connection not only ensures the flexible rotation of the first drive shaft 6 and reduces the frictional resistance during rotation, but also forms an effective seal at the connection between the flotation box 1 and the first drive shaft 6 to prevent the slurry from leaking from the gap.

[0027] Furthermore, the lead screw 15 is connected to the dosing pipe 2 by a bearing. Through the setting of the lead screw 15 and the dosing pipe 2, the bearing connection enables the lead screw 15 to rotate smoothly, ensuring the displacement accuracy of the sliding plate 14, which facilitates precise control of the amount of agent delivered. At the same time, combined with the skeleton oil seal at the bearing, it can effectively prevent the agent from leaking from the connection gap, ensuring the sealing of the dosing system.

[0028] Furthermore, the second drive shaft 10 is connected to the flotation box 1 bearing. Through the arrangement of the second drive shaft 10 and the flotation box 1, the bearing connection ensures that the second drive shaft 10 is flexible and stable when driving the discharge blade 11 to rotate, reducing operating noise and energy consumption, while preventing the slurry from leaking from the connection between the drive shaft and the flotation box 1, ensuring the sealing and reliability of the discharge process.

[0029] Working principle: During flotation, the handle of screw 15 is manually turned first. Screw 15 is connected to the bearing of dosing pipe 2, and a skeleton oil seal is provided at the bearing of screw 15 to ensure sealing. Since screw 15 is threadedly connected to the sliding plate 14 on the surface of the sliding groove 13 on the inner wall of the reagent tank 12, the rotation of screw 15 will drive the sliding plate 14 to move along the sliding groove 13, thereby pushing the reagent in the reagent tank 12 to flow along the inclined dosing pipe 2; at this time, the reagent in the dosing pipe 2... The one-way valve 16 on the wall is open, allowing the reagent to flow from the storage tank 12 into the flotation tank 1. The reagent is conveyed by gravity pressure formed by the height difference of the storage tank 12. At the same time, because the outer edge of the impeller 7 is a negative pressure adsorption zone when it rotates, one end of the dosing pipe 2 is located above the edge of the impeller 7. The negative pressure actively "absorbs" the reagent, forming a dual effect of "gravity pressure conveying + negative pressure adsorption", so that the reagent is stably delivered to the flotation tank 1 above the edge of the impeller 7. In addition, the one-way valve 16 can prevent the slurry from flowing back into the dosing pipe 2 due to the liquid level difference when the machine is stopped. Subsequently, an external air source delivers air through the air supply pipe 3. A filter screen at the connection point of the air supply pipe 3 filters impurities. After being transmitted through the connecting pipe 4, the air flows from the through-holes on the surface of the fixed plate 8 to the impeller 7 area. Simultaneously, the first drive motor 5 is activated, its output driving the first transmission shaft 6, connected to the bearing of the flotation box 1, to rotate. The spiral impeller 7, composed of three spiral blades, on the surface of the first transmission shaft 6 rotates accordingly. This rotation causes the slurry to tumble up and down, ensuring thorough mixing of the reagents and slurry. Simultaneously, it breaks the air flowing in from the through-holes of the fixed plate 8 into tiny bubbles, meeting the bubble requirements for flotation. After the slurry completes the flotation reaction of reagent action and bubble attachment within the flotation box 1, the second drive motor 9 is activated. Its output driving the second transmission shaft 10, connected to the bearing of the flotation box 1, to rotate. The discharge blades 11 on the surface of the second transmission shaft 10 rotate accordingly, ultimately discharging the flotation-completed slurry from the flotation box 1, completing the entire flotation process and significantly improving the efficiency of the flotation reaction.
