[0084] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0085] like Figure 1 , Figure 5 and Figure 8 As shown, the present invention provides a quartz sand flotation device, including a flotation component 1, a washing component 2, a housing component 3, a stirring component 4, and a transfer component 5. The flotation component 1 includes a first flotation tank 11, a second flotation tank 12, and a third flotation tank 13; the washing component 2 includes a first washing tank 21; the housing component 3 includes a filter cylinder 31, which is hollow inside and open at the top; the stirring component 4 has a fixed end and a stirring end, the fixed end of the stirring component 4 is connected to the filter cylinder 31, and the stirring end is built into the filter cylinder 31; the transfer component 5 is detachably connected to the filter cylinder 31 and is used to drive the filter cylinder 31 to transfer between the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, and the first washing tank 21.

[0086] Specifically, quartz sand is fed into filter cartridge 31; the filter cartridge 31 containing the material is moved to the first flotation tank 11 by the transfer component 5, and the solution in the first flotation tank 11 enters the filter cartridge 31 through the filter holes. The stirring component 4 is activated to float silicate minerals; the filter cartridge 31 containing the material is detached from the first flotation tank 11 by the transfer component 5, and during the detachment process, the solution in the filter cartridge 31 flows back into the first flotation tank 11, while the quartz sand is trapped inside the filter cartridge 31; the filter cartridge 31 containing the material is transferred to the second flotation tank 12 by the transfer component 5, and the solution in the second flotation tank 12 enters the filter cartridge 31 through the filter holes. The stirring component 4 is activated to float impurities and iron-containing minerals introduced during production; the filter cartridge 31 containing the material is detached from the second flotation tank 12 by the transfer component 5, and during the detachment process, the solution in the filter cartridge 31 flows back into the second flotation tank 12, while the quartz sand is trapped inside the filter cartridge 31. The filter cartridge 31 containing material is transferred to the third flotation tank 13 via the transfer component 5. The solution in the third flotation tank 13 enters the filter cartridge 31 through the filter holes, and the stirring component 4 is activated to float the transition metal minerals. The filter cartridge 31 containing material is then removed from the third flotation tank 13 via the transfer component 5. During the removal process, the solution in the filter cartridge 31 flows into the third flotation tank 13, and the quartz sand is trapped inside the filter cartridge 31. The filter cartridge 31 containing material is then transferred to the first washing tank 21 via the transfer component 5. The first washing tank 21 contains a solution containing a cleaning agent. The solution enters the filter cartridge 31 through the filter holes, and the stirring component 4 is activated to wash the quartz sand in the filter cartridge 31. After washing, the filter cartridge 31 containing material is removed from the first washing tank 21 via the transfer component 5, and the transfer component 5 is also removed from the first washing tank 21. Finally, the material in the first washing tank 21 is removed.

[0087] In this application, the quartz sand is processed sequentially through the first flotation tank 11, the second flotation tank 12, and the third flotation tank 13, which can effectively remove impurities from the quartz sand and improve its purity. Moreover, the quartz sand is floated sequentially by the first flotation tank 11, the second flotation tank 12, and the third flotation tank 13 in the filter cartridge 31, using only a portion of the solution in the first flotation tank 11. The solutions in the first flotation tank 11, the second flotation tank 12, and the third flotation tank 13 can continuously float the quartz sand without the need to add a regulator to the first flotation tank 11, the second flotation tank 12, and the third flotation tank 13 to adjust the pH, thus making full use of the solution used for flotation.

[0088] like Figure 8As shown, in one embodiment, the receiving component 3 further includes a sleeve 32, a liquid inlet 33, and a liquid outlet 34. The sleeve 32 is fitted onto the filter cartridge 31, forming a receiving cavity between the sleeve 32 and the filter cartridge 31. The receiving cavity is connected to the interior of the filter cartridge 31 through the filter holes of the filter cartridge 31. The liquid inlet 33 includes a liquid inlet pipe 331 and a first control unit 332. The liquid inlet pipe 331 is connected to the sleeve 32 and is connected to the receiving cavity. The first control unit 332 is disposed on the liquid inlet pipe 331 and is used to control the opening and closing of the liquid inlet pipe 331. The liquid outlet 34 includes a liquid outlet pipe 341 and a second control unit 342. The liquid outlet pipe 341 is connected to the sleeve 32 and is connected to the receiving cavity. The second control unit 342 is disposed on the liquid outlet pipe 341 and is used to control the opening and closing of the liquid outlet pipe 341.

[0089] By setting up the receiving component 3, when the receiving component 3 moves into the flotation tank under the action of the transfer component 5, the liquid inlet 33 is opened, and the solution in the flotation tank enters the sleeve 32 through the liquid inlet 33 and enters the filter cartridge 31 through the filter hole. When a certain amount of solution has entered, the liquid inlet pipe 331 is closed by the first control unit 332, and then the stirring component 4 is started. The stirring component 4 stirs the solution and quartz sand to float the quartz sand. During the flotation, the foam formed is discharged through the sleeve 32. The foam formed during the stirring process will not be unable to enter the flotation tank through the sleeve 32, and the stirring will not affect the solution in the flotation tank. After the flotation is completed, the receiving component 3 is lifted by the transfer component 5. During the lifting process, the solution in the filter cartridge 31 flows out of the filter cartridge 31 through the filter hole through the second control unit 342 and is discharged into the corresponding flotation tank through the discharge pipe 341, which can fully recover the unreacted components in the solution.

[0090] It should be understood that the first control unit 332 and the second control unit 342 can be solenoid valves, hydraulic valves, and pneumatic valves, etc.

[0091] like Figure 5 As shown, in one embodiment, the flotation assembly 1 further includes three overflow members 14, which are respectively disposed in the first flotation tank 11, the second flotation tank 12 and the third flotation tank 13. The overflow members 14 have through holes that are connected to the corresponding flotation tanks. The overflow members 14 have overflow grooves around the through holes. The sleeve 32 can be inserted into the through holes.

[0092] By setting the overflow component 14, when the stirring component 4 is stirring, the foam and impurities formed in the sleeve 32 overflow outward from the open end of the sleeve 32. During the overflow process, the overflowing foam enters the overflow groove of the overflow component 14 through the open end of the sleeve 32 and flows away from the overflow groove. By setting the overflow groove, the overflowing foam and impurities can be collected and treated.

[0093] It should be understood that the overflow channel is an annular channel with an opening at the top, and the overflow component 14 passes through one side.

[0094] like Figure 6 and Figure 8 As shown, in one embodiment, the receiving component 3 further includes a retaining ring 35, which connects the sleeve 32 and the filter cartridge 31 and is able to abut against the overflow groove when the sleeve 32 is inserted into the through hole.

[0095] By setting a retaining ring 35, when the sleeve 32 is inserted into the flotation tank, the retaining ring 35 abuts against the overflow member 14. By setting the retaining ring 35, the retaining ring 35 can support the sleeve 32 inserted into the flotation tank. Moreover, the retaining ring 35 can block the gap between the sleeve 32 and the flotation tank, so that the foam formed by the overflow can enter the overflow trough through the retaining ring 35, and prevent the foam from entering the flotation tank from the gap between the sleeve 32 and the flotation tank.

[0096] like Figure 8 As shown, in one embodiment, the receiving component 3 further includes a discharge component 36, which includes a discharge pipe 361 and a third control unit 362. The feed end of the discharge pipe 361 extends into the sleeve 32 and is connected to the filter cartridge 31. The third control unit 362 is disposed in the discharge pipe 361 and is used to control the opening and closing of the discharge pipe 361.

[0097] Specifically, by setting up the discharge component 36, when it is necessary to discharge the quartz sand in the filter cartridge 31, the discharge pipe 361 is opened by the third control unit 362, and the quartz sand in the filter cartridge 31 is discharged through the discharge pipe 361, thus realizing the discharge of the quartz sand in the filter cartridge 31.

[0098] It should be understood that the third control unit 362 can be a solenoid valve, hydraulic valve, or pneumatic valve, etc.

[0099] like Figure 1 and Figure 5 As shown, in one embodiment, the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, and the first washing tank 21 are arranged linearly; the transfer assembly 5 includes a bracket 51, a slide rail 52, a sliding member 53, a drive member 54, a lifting member 55, and a connecting member 56. The slide rail 52 is connected to the bracket 51 and is arranged along the arrangement direction of the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, and the first washing tank 21. The sliding member 53 is slidably connected to the slide rail 52. The drive member 54 is connected to the sliding member 53 and the slide rail 52 and is used to drive the sliding member 53 to slide relative to the slide rail 52. The lifting member 55 has a fixed end and a lifting end. The fixed end of the lifting member 55 is connected to the sliding member 53. The connecting member 56 is connected to the lifting end of the lifting member 55. The connecting member 56 can be connected to or disconnected from the sleeve 32.

[0100] Specifically, when the receiving component 3 needs to be transferred sequentially between the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, and the first washing tank 21, the sleeve 32 is connected by the connector 56, and then the sleeve 32 and the connector 56 are raised and lowered by the lifting component 55. After the sleeve 32 is detached from the tank, the drive component 54 is activated, and the drive component 54 drives the sliding component 53 and the receiving component 3 to slide along the guide rail 52 until the receiving component 3 moves above the next tank. At this time, the sleeve 32 and the connector 56 are lowered by the lifting component 55 until the sleeve 32 is inserted into the next tank. At this time, the connector 56 is disengaged from the sleeve 32 to achieve the separation of the sleeve 32 from the connector 56. Through the above settings, the receiving component 3 can be transferred between the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, and the first washing tank 21.

[0101] It should be understood that the driving component 54 can be a roller or gear driven by a servo motor, or a roller or gear driven by a hydraulic motor. The roller rolls in contact with the slide rail 52, and the rotation of the roller drives the sliding component 53 to slide relative to the slide rail 52. The lifting component 55 can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, or a gear and rack structure set vertically and driven by a servo motor. The connecting component 56 can be a clamping claw, a clamping arm, etc.

[0102] In one embodiment, the retaining ring 35 is made of ferromagnetic material; the connector 56 is an electromagnetic adsorption structure, which can electromagnetically adsorb the retaining ring 35 when energized and release the retaining ring 35 when de-energized.

[0103] When it is necessary to connect the connector 56 and the retaining ring 35, the connector 56 is energized. The energized connector 56 forms an electromagnetic attraction force and is electromagnetically attracted to the retaining ring 35. The retaining ring 35 and the connector 56 are connected through electromagnetic attraction, thus realizing the connection between the connector 56 and the retaining ring 35.

[0104] It should be understood that electromagnetic adsorption structures include electromagnetic coils, electromagnetic chucks, etc.

[0105] like Figure 8 As shown, in one embodiment, the stirring assembly 4 includes a fixed frame 41, a stirring shaft 42, multiple blades 43, and a motor 44. The fixed frame 41 is connected to the sleeve 32 and the filter cylinder 31. The stirring shaft 42 is rotatably connected to the fixed frame 41, and one end extends into the filter cylinder 31. The multiple blades 43 are all built into the filter cylinder 31 and connected to the stirring shaft 42. The motor 44 is fixed to the fixed frame 41, and its output shaft is connected to the stirring shaft 42.

[0106] When the quartz sand to be floated and washed needs to be stirred by the stirring assembly 4, the motor 44 is started. The motor 44 drives the stirring shaft 42 to rotate, and the stirring shaft 42 drives multiple blades 43 to rotate. The rotating blades 43 stir the quartz sand located in the filter cylinder 31 to promote the contact between the quartz sand and the solution and to promote the formation of flotation foam.

[0107] An electrical contact can be provided in the overflow component 14. When the electrical contact abuts against the retaining ring 35, power is supplied to the motor 44 through the retaining ring 35. Alternatively, a battery that supplies power to the motor 44 can be provided on the mounting bracket 41.

[0108] like Figure 5 As shown, in one embodiment, the cleaning assembly 2 further includes a second cleaning tank 22 and a collection tank 23. The first flotation tank 11, the second flotation tank 12, the third flotation tank 13, the first cleaning tank 21, the second cleaning tank 22, and the collection tank 23 are arranged linearly. The second cleaning tank 22 is filled with water. The collection tank 23 includes a tank body 231 and a screen 232. The tank body 231 is hollow inside and open at the top. The screen 232 is built into the tank body 231 and is disposed at the open end of the tank body 231. The transfer assembly 5 can drive the filter cartridge 31 to transfer between the first flotation tank 11, the second flotation tank 12, the third flotation tank 13, the first cleaning tank 21, the second cleaning tank 22, and the collection tank 23.

[0109] Specifically, when it is necessary to separate quartz sand from the filter cartridge 31, the filter cartridge 31 containing quartz sand is transferred to the second washing tank 22 via the transfer assembly 5. The inlet pipe 331 is opened by the first control unit 332, allowing water to enter the sleeve 32 and the filter cartridge 31 through the inlet pipe 331. When the sleeve 32 is full of water, the inlet pipe 331 is closed by the first control unit 332. Then, the filter cartridge 31 containing water and quartz sand is transferred to the collection tank 23 via the transfer assembly 5. It is set above the screen 232. The third control unit 362 controls the discharge pipe 361 to open. The quartz sand flows from the discharge pipe 361 to the screen 232 under the carry of water. The screen 232 intercepts the quartz sand, and the water flows directly through, realizing the discharge of quartz sand from the filter cylinder 31. Moreover, the impact of the water flow can prevent the quartz sand from adhering to the inside of the filter cylinder 31. The screen 232 can separate the quartz sand and water. The water is collected by the collection tank 23 and can be reused.

[0110] The present invention also relates to a method for flotation of quartz sand, using the above-described quartz sand flotation apparatus, comprising the following steps:
