Description

Technical Field

[0001] This application relates to the field of quartz sand flotation, and more specifically, to a flotation machine for quartz sand purification. Background Technology

[0002] Quartz sand flotation is a key mineral processing technology that separates target minerals from quartz sand ore and improves the purity and quality of quartz sand based on the differences in the physicochemical properties of mineral surfaces. During flotation, specific flotation reagents are added to the slurry to alter the hydrophobicity of the quartz sand particles and impurity minerals. Then, a large number of tiny bubbles are formed by the introduction of gas. The highly hydrophobic target quartz sand particles adhere to the bubble surface, rise with the bubbles to form a foam layer, and are subsequently scraped off, achieving separation from gangue and other impurities. It is widely used in many industries with high purity requirements for quartz sand, such as glass manufacturing, casting, and electronic semiconductors.

[0003] However, in practical applications, existing quartz sand flotation equipment often suffers from a lack of effective material distribution structure, resulting in concentrated quartz sand falling and localized quartz sand accumulation. Furthermore, the generated bubbles vary in size and are unevenly distributed. The uneven and larger bubbles cannot effectively contact more quartz sand particles, resulting in weak collection capacity and affecting flotation accuracy and recovery rate. Therefore, this application proposes a flotation machine for quartz sand purification. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a flotation machine for quartz sand purification, thereby solving the problem of poor flotation effect of quartz sand in existing technologies.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A flotation machine for purifying quartz sand includes a flotation tank with a stirring mechanism inside. A feed inlet is located at the top of the side wall of the flotation tank, and a tailings outlet is located at the bottom of the side wall. A gas pipe is horizontally arranged at the bottom of the flotation tank, above the tailings outlet. Multiple gas distribution branches are arranged on the gas pipe, pointing vertically upwards and evenly distributed along the length of the flotation tank. A distribution pipe is located at the top of the flotation tank, connected to the feed inlet. The distribution pipe is annular, and multiple distribution branches are vertically and evenly arranged at its bottom, connected to the distribution pipe.

[0008] Furthermore, a ring platform is provided at the top of the flotation tank, the diameter of the ring platform is larger than the diameter of the flotation tank, and a fine material discharge port is provided on the side wall of the ring platform.

[0009] Furthermore, the flotation tank is provided with a gas supply connector connected to the gas pipe on its side wall, and each gas branch pipe is provided with a one-way valve. The flotation tank is also provided with a chemical dosing port located below the distribution pipe.

[0010] Furthermore, the material distribution pipe is inclined downwards towards the side away from the feed port, and a feed connector is provided on the material distribution pipe, through which the feed port is connected to the material distribution pipe.

[0011] Furthermore, a gathering hood is suspended and fixed above the trachea. The gathering hood is configured as a bucket-shaped structure with a gathering opening at the center of the top of the gathering hood. A skirt is provided on the periphery of the bottom of the gathering hood. The gathering hood, together with the skirt, covers multiple gas branch pipes inside.

[0012] Furthermore, a platform is horizontally fixed at the top of the ring platform, and a bracket is fixed at the top of the platform. The stirring mechanism includes a vertical shaft that passes through the center of the flotation tank. A flow divider is provided at the bottom of the shaft, which is located above the collection hood. A stirring blade is provided in the middle of the shaft, which is located below the distribution pipe. A motor is installed on the bracket, and the top of the shaft is connected to the output end of the motor.

[0013] Furthermore, the diversion hood is configured as a bucket-shaped structure, and the radius of the diversion hood is smaller than the radius of the gathering hood but larger than the radius of the gathering opening. Multiple stirring support rods are provided around the diversion hood.

[0014] The beneficial effects of this application are as follows:

[0015] By setting the distribution pipes in a circular and inclined manner, and setting multiple distribution branch pipes at the bottom, the quartz sand can be evenly dispersed and fall, allowing the quartz sand to fully contact the reagents, improving the effect of the reagents on the quartz sand, and thus improving the flotation efficiency.

[0016] Through the special structural design of the gathering and dispersing hoods, combined with the stirring rods, the gas can be first gathered and then evenly dispersed, finally breaking into a large number of tiny bubbles. These tiny bubbles have a larger specific surface area, allowing them to contact more quartz sand particles, thus improving the bubbles' ability to collect quartz sand particles and consequently increasing flotation accuracy and recovery rate.

[0017] The stirring blades and diverter in the stirring mechanism rotate under the drive of the shaft, which can fully stir the quartz sand and air bubbles in the flotation tank, making the mixing between the quartz sand, reagents and air bubbles more uniform and further improving the flotation effect.

[0031] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Reference Figure 1-4 As shown, this utility model provides a flotation machine for quartz sand purification, including a flotation tank 1, which is used to contain quartz sand, reagents, and to carry out flotation reactions. A ring platform 2 is provided at the top of the flotation tank 1, the diameter of which is larger than the diameter of the flotation tank 1. A concentrate discharge port 4 is provided on the side wall of the ring platform 2 for discharging the quartz concentrate that has floated to the surface after flotation. A feed port 3 is provided at the top of the side wall of the flotation tank 1, and a tailings discharge port 5 is provided at the bottom of the side wall for discharging the tailings that have settled after flotation.

[0033] Furthermore, in this embodiment, a gas pipe 11 is horizontally arranged at the bottom of the flotation tank 1, located above the tail material discharge outlet 5. Multiple gas branch pipes 12 are arranged on the gas pipe 11, pointing vertically upwards and evenly distributed along the length of the flotation tank 1. A gas supply connector 17, communicating with the gas pipe 11, is provided on the side wall of the flotation tank 1 for supplying gas into the gas pipe 11. Each gas branch pipe 12 is equipped with a one-way valve to prevent liquid backflow into the gas pipe 11.

[0034] Furthermore, in this embodiment, a distribution pipe 10 is provided at the top of the flotation tank 1. The distribution pipe 10 is circular and is inclined downwards towards the side away from the feed port 3. Multiple distribution branch pipes 19 are vertically and evenly arranged at the bottom of the distribution pipe 10. The distribution branch pipes 19 are connected to the distribution pipe 10. Specifically, a feed connector 18 is provided on the distribution pipe 10. The feed port 3 is connected to the distribution pipe 10 through the feed connector 18. After the quartz sand enters the distribution pipe 10 through the feed port 3, it is dispersed and falls down by the multiple distribution branch pipes 19.

[0035] Furthermore, in this embodiment, a gathering cover 13 is suspended and fixed above the air pipe 11. The gathering cover 13 is configured as a bucket-shaped structure. A gathering opening 21 is provided at the center of the top of the gathering cover 13. A skirt 20 is provided on the periphery of the bottom end of the gathering cover 13. The gathering cover 13, together with the skirt 20, covers multiple air distribution branches 12 inside, so that the gas blown out from the air distribution branches 12 can be gathered and overflow from the gathering opening 21 and float upward.

[0036] In a further embodiment, a stirring mechanism is also provided inside the flotation tank 1. The stirring mechanism includes a vertically centered shaft 9 that passes through the flotation tank 1. A flow divider 14 is provided at the bottom end of the shaft 9, which is located above the collection hood 13. An agitator blade 15 is provided in the middle of the shaft 9, which is located below the distribution pipe 10. A platform 6 is horizontally fixed at the top of the flotation tank 1. A bracket 7 is fixed at the top of the platform 6. A motor 8 is installed on the bracket 7. The top end of the shaft 9 is connected to the output end of the motor 8. The motor 8 drives the shaft 9 to rotate, which in turn drives the agitator blade 15 and the flow divider 14 to rotate. The flow divider 14 is also configured as a bucket-shaped structure. The radius of the flow divider 14 is smaller than the radius of the collection hood 13 but larger than the radius of the collection opening 21. Multiple stirring rods 22 are provided around the flow divider 14. The gas overflowing from the collection opening 21 is evenly dispersed by the flow divider 14 and further dispersed into fine bubbles by the multiple stirring rods 22.

[0037] Furthermore, a chemical dosing port 16 is provided on the side wall of the flotation tank 1. The chemical dosing port 16 is located below the feed distribution pipe 10 and above the stirring blade 15. Frothing agents, collectors, inhibitors and other reagents are added into the flotation tank 1 through the chemical dosing port 16.

[0038] Working Principle: This flotation machine for quartz sand purification operates as follows: Water is injected into flotation tank 1, and appropriate amounts of frothers, collectors, and depressants are added through the reagent inlet 16. These reagents alter the physicochemical properties of the quartz sand particles, giving them varying degrees of hydrophobicity. Then, motor 8 is started, activating the stirring mechanism. Simultaneously, quartz sand is fed into the feed inlet 3, passing through the feed connector 18 into the distribution pipe 10, and then dispersed and fallen through multiple distribution branches 19, making full contact with the reagents during its descent. At the same time, gas is fed into the gas pipe 11 through the gas inlet 17, and then blown out through multiple gas distribution branches 12. After being gathered by the collecting hood 13, the gas overflows and floats upwards from the collecting port 21, is evenly dispersed by the distribution hood 14, and then broken into fine bubbles by multiple stirring rods 22. As these tiny bubbles rise, they mix thoroughly with the dispersed quartz sand. Under the action of the collector, the hydrophobic quartz sand particles adhere to the surface of the bubbles and rise with them to the platform 2, then are discharged from the concentrate outlet 4. Hydrophilic impurity particles, however, do not adhere to the bubbles and settle at the bottom of the flotation tank 1, being discharged from the tailings outlet 5, thus achieving the separation and purification of quartz sand and impurities. The shaft 9 of the stirring mechanism rotates under the drive of the motor 8, and the rotation of the stirring blades 15 disperses the quartz sand, allowing it to mix more thoroughly with the reagents, while also facilitating contact and adhesion between the bubbles and the quartz sand. The rotation of the diverter hood 14 further disperses the bubbles evenly, improving the flotation effect.
