Description

Technical Field

[0001] This invention relates to the field of purification technology, and in particular to a purification device and method for high-purity quartz sand. Background Technology

[0002] Quartz sand is a granular material formed by crushing quartz stone and is widely used in chemical, construction, and other fields. Natural quartz sand contains various metal compounds. To improve the purity of the finished quartz sand and meet usage requirements, it needs to be acid-washed during processing to remove metal impurities. Some companies use horizontal rotary drums for acid washing, while others use belt conveyors. These acid washing processes can continuously produce large quantities of quartz sand particles, meeting the needs of large-scale continuous production. However, they suffer from drawbacks such as excessive equipment footprint, large acid washing space, and difficulty in controlling the acid washing ratio and effect. Using a vertical conical agitator for agitation and acid washing can effectively overcome some of the shortcomings of the above-mentioned acid washing methods.

[0003] Application number is 202310523434 Chinese Patent No. 9 discloses a high-purity quartz sand purification and pickling equipment, comprising: a pickling tank for containing quartz sand; the pickling tank includes a through main body, with a first pickling section and a second pickling section respectively provided at both axial ends of the main body, and a hollow conveying shaft connected to both radial sides of the main body; a support base for controlling the rotation of the pickling tank and providing rotation space for the pickling tank; a feeding device connected to the first end of the conveying shaft for directional conveying of quartz sand into the pickling tank; an acid pumping device connected to the second end of the conveying shaft for conveying pickling liquid into the pickling tank; a dividing assembly disposed within the main body of the pickling tank for dividing the pickling tank into a first pickling chamber and a second pickling chamber, the dividing assembly being connected to the feeding device and the acid pumping device respectively, and having a first receiving groove and a second receiving groove extending vertically through the dividing assembly; a first conductive assembly connected to the acid pumping device installed in the first receiving groove, the first conductive assembly having a position-adjustable first conductive part. The first through-hole is used to guide the pickling liquid provided by the acid pumping device into the first pickling chamber or the second pickling chamber; the second receiving tank is equipped with a second through-assembly component connected to the feeding device. The second through-assembly component has an adjustable discharge opening, which is used to transport the quartz sand provided by the feeding device to the first pickling chamber or the second pickling chamber. The second through-assembly component also has an adjustable second through-hole, which is used to control the directional flow of the pickling liquid between the first pickling chamber and the second pickling chamber. Although this scheme can improve the utilization efficiency of the pickling liquid and provide the pickling effect for pickling quartz sand, during the pickling process, because the pickling liquid reacts with the quartz sand, some quartz sand will remain on the side wall of the conical agitator and will not flow with the pickling liquid. This results in the quartz sand adhering to the side wall not being thoroughly pickled. At the same time, during the process of removing the pickled quartz sand, the quartz sand remaining on the side wall cannot be rinsed off, resulting in the quartz sand not being completely cleaned off.

[0004] Therefore, a purification device and method for high-purity quartz sand are invented to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a purification device and method for high-purity quartz sand, which can effectively solve the technical problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a purification device for high-purity quartz sand, comprising an acid washing tank and a support base, and further comprising: The rinsing assembly includes two rinsing rings fixedly connected to the pickling tank. Multiple rinsing holes are provided on the opposite sides of the two rinsing rings, and a mass ring is slidably connected inside the rinsing ring. An adjustment assembly includes an adjustment ring rotatably connected to the flushing ring. The adjustment ring has multiple first adjustment holes and second adjustment holes corresponding to the flushing holes. When the mass ring slides toward the flushing hole, the adjustment ring drives the first adjustment hole to communicate with the flushing hole for flushing. When the mass ring slides in the opposite direction to the flushing hole, the adjustment ring drives the second adjustment hole to communicate with the flushing hole for liquid storage. A partition assembly, located between the two rinse rings, is used to divide the pickling tank into two independent pickling chambers.

[0007] Preferably, the adjusting assembly includes a receiving cavity formed on the flushing ring, a first push block is fixed on the adjusting ring, and a second push block is fixed to the first push block via a connecting rod, with both the first push block and the second push block located within the receiving cavity.

[0008] Preferably, an auxiliary rod is fixed to one end of the mass ring away from the flushing hole, the free end of the auxiliary rod extends into the receiving cavity and is fixed with a vertically extending push rod, both ends of the push rod being able to contact the end faces of the corresponding first push block and second push block.

[0009] Preferably, the opposite ends of the first push block and the second push block are both connected to the sidewall of the receiving cavity via elastic elements.

[0010] Preferably, the diameter of the first adjusting hole is smaller than the diameter of the rinsing hole, which is used to increase the rinsing pressure of the pickling solution, and the opposing surfaces of the first push block and the second push block are both inclined surfaces and parallel to each other.

[0011] Preferably, the pickling tank includes a cylindrical main body and a symmetrical and conical pickling section, and the two sides of the pickling tank are rotatably connected to the support base via rotating shafts.

[0012] Preferably, the rinsing hole is inclined, with its inclination angle matching that of the pickling section and being close to the pickling section, for better rinsing of the sidewalls of the pickling section.

[0013] Preferably, each of the two opposite ends of the pickling section is fixed with a control valve for controlling the discharge of pickling solution and quartz sand in the pickling section.

[0014] Preferably, the partition assembly includes two partition plates fixedly connected to the pickling tank, and an acid pump assembly and a feeding assembly are arranged between the partition plates for injecting pickling solution and quartz sand into the pickling tank for pickling.

[0015] A method for purifying high-purity quartz sand includes the following steps: S1: First, the quartz sand is fed into the pickling tank through the feeding assembly, and the pickling liquid is pumped into the pickling tank through the pumping assembly. Then, the pickling tank is rotated to perform mixed pickling. S2: Then, acid is pumped into the pickling section through the separation assembly and the acid pumping assembly, and the acid in the upper pickling section flows into the lower pickling section through the feeding assembly for pickling again. S3: Next, the sidewall of the pickling section is rinsed by the rinsing assembly, which can also impact the quartz sand to a certain extent and improve the pickling effect. S4: Finally, open the control valve on the lower pickling section so that the rinsing assembly rinses the residual quartz sand on the side wall of the pickling section, thus preventing quartz sand from remaining on the side wall of the pickling section.

[0016] The technical effects and advantages of this invention are as follows: This invention, through the coordinated arrangement of a mass ring, an adjusting ring, a rinsing hole, a first pusher block, and a second pusher block, allows the pickling solution to be stored in the rinsing ring through the rinsing hole and the second adjusting hole during the continuous rotation of the pickling tank. Furthermore, the gravitational potential energy of the mass ring forces the pickling solution in the rinsing ring through the first adjusting hole and the rinsing hole under pressure, thereby enabling the pickling solution to rinse away residual quartz sand in the pickling section, reducing the occurrence of residue problems. Simultaneously, the pressurized and extruded pickling solution also improves the effect of mixed pickling of quartz sand and ensures that the quartz sand is thoroughly removed from the pickling section, improving the efficiency and quality of quartz sand pickling and purification.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figure 1 and Figure 2 As shown, this embodiment also provides a purification device for high-purity quartz sand, including an acid washing tank 1 and a support 2, and further including a rinsing assembly 3, which includes two rinsing rings 301 fixedly connected to the acid washing tank 1. Multiple rinsing holes 302 are opened on the opposite sides of the two rinsing rings 301, and a mass ring 303 is slidably connected inside the rinsing rings 301.

[0020] The partition assembly 5, located between the two rinsing rings 301, is used to divide the pickling tank 1 into two independent pickling chambers.

[0021] Pickling tank 1 includes a cylindrical main body 101 and a symmetrical and conical pickling section 102. Both sides of the pickling tank 1 are rotatably connected to the support base 2 via a rotating shaft 103.

[0022] Both pickling sections 102 are fixed with control valves 104 at opposite ends to control the discharge of pickling solution and quartz sand in the pickling section 102.

[0023] The partition assembly 5 includes two partition plates 501 that are fixedly connected to the pickling tank 1. A pumping assembly 6 and a feeding assembly 7 are arranged between the partition plates 501 for injecting pickling solution and quartz sand into the pickling tank 1 for pickling.

[0024] In actual use, quartz sand is first fed simultaneously into the two pickling sections 102 on the pickling tank 1 via the feeding assembly 7, and the pickling solution is injected directionally into the pickling section 102 via the pump acid assembly 6 for pickling. It should be noted that both the pump acid assembly 6 and the feeding assembly 7 are located between the rotating shaft 103, the pickling tank 1, and the partition plate 501, and are existing technologies. The specific structure and connection method will not be described in detail. Since a drive structure is provided in the bearing seat 2, which is an existing technology, it is used to drive the pickling tank 1 to rotate along the bearing seat 2. When the pickling tank 1 rotates, in the main body 101, The combined action of the partition plate 501 and the two conical pickling sections 102 enables the pickling solution and quartz sand to be thoroughly mixed and pickled, improving the effect and efficiency of pickling and purifying the quartz sand. The two independently existing pickling sections 102 can not only directionally control the injection of the pickling solution, but also control the pickling solution to mix with the new quartz sand through the feeding component 7 when new quartz sand is fed into the pickling tank 1, thus improving the utilization rate of the pickling solution. After the quartz sand is pickled, the control valve 104 is opened to allow the quartz sand and pickling solution to flow out from the opening end of the pickling section 102 for subsequent steps. Example

[0025] During use, it was found that when the pickling tank 1 is rotating, some quartz sand remains on the side wall of the pickling section 102 located below, and does not flow with the pickling liquid. This results in the quartz sand adhering to the pickling section 102 not being thoroughly pickled. At the same time, during the process of removing the quartz sand from the pickling section 102, the residue on the side wall of the pickling section 102 is not rinsed, resulting in the quartz sand not being thoroughly removed from the pickling tank 1. Therefore, further improvements were made based on the above embodiment.

[0026] like Figures 2 to 9 As shown, the adjustment component 4 includes an adjustment ring 401 rotatably connected to the flushing ring 301. The adjustment ring 401 has a plurality of first adjustment holes 402 and second adjustment holes 403 corresponding to the flushing holes 302. When the mass ring 303 slides toward the flushing hole 302, the adjustment ring 401 drives the first adjustment hole 402 to communicate with the flushing hole 302 for flushing. When the mass ring 303 slides in the opposite direction to the flushing hole 302, the adjustment ring 401 drives the second adjustment hole 403 to communicate with the flushing hole 302 for liquid storage.

[0027] The adjustment assembly 4 includes a receiving cavity 404 opened on the flushing ring 301. A first push block 405 is fixed on the adjustment ring 401. A second push block 406 is fixed to the first push block 405 through a connecting rod. Both the first push block 405 and the second push block 406 are located in the receiving cavity 404.

[0028] An auxiliary rod 407 is fixed to one end of the mass ring 303 away from the flushing hole 302. The free end of the auxiliary rod 407 extends into the receiving cavity 404 and is fixed with a vertically extending push rod 408. Both ends of the push rod 408 can contact the end faces of the corresponding first push block 405 and second push block 406.

[0029] The opposite ends of the first pusher 405 and the second pusher 406 are both connected to the side wall of the receiving cavity 404 through the elastic element 409.

[0030] The diameter of the first adjusting hole 402 is smaller than the diameter of the rinsing hole 302, which is used to increase the rinsing pressure of the pickling solution. The opposing surfaces of the first push block 405 and the second push block 406 are both inclined surfaces and parallel to each other.

[0031] The rinsing hole 302 is tilted, and its tilt angle is the same as that of the pickling section 102 and close to the pickling section 102, so as to better rinse the side wall of the pickling section 102.

[0032] In actual use, during the rotation of the pickling tank 1, the pickling tank 1 drives the rinsing ring 301 to rotate synchronously. When the pickling tank 1 rotates from a horizontal to a vertical position, the mass ring 303 in the rinsing ring 301 located on the lower side slides along the rinsing ring 301 towards the rinsing hole 302. Due to the large mass of the mass ring 303, it can overcome the resistance of the pickling liquid and slide downwards. As the pickling tank 1 rotates from a horizontal to a vertical position, the downward sliding speed of the mass ring 303 gradually increases. The mass ring 303 drives the auxiliary rod 407 to slide along the receiving cavity 404. The auxiliary rod 407 drives the push rod 408 to slide towards the rinsing hole 302. At this time, the push rod 408 no longer presses the second push block 406. Under the action of the elastic element 409, the elastic element 409 drives the adjusting ring 401 to rotate through the second push block 406, so that the adjusting ring 401 drives the second adjusting hole 403 to no longer communicate with the rinsing hole 302, so that the pickling liquid can be stored in the rinsing ring 301.

[0033] When one end of the push rod 408 gradually presses the first push block 405, since the opposing surfaces of the first push block 405 and the second push block 406 are both inclined, the push rod 408 can drive the adjusting ring 401 to rotate along the flushing ring 301 through the inclined surface of the first push block 405. As a result, the adjusting ring 401 drives the first adjusting hole 402 to gradually connect with the flushing hole 302. Since the diameter of the first adjusting hole 402 is smaller than the diameter of the flushing hole 302, when the mass ring 303 slides towards the flushing hole 302, the flushing pressure when the pickling liquid in the flushing ring 301 is squeezed out from the first adjusting hole 402 through the flushing hole 302 is greater, which facilitates better flushing of the quartz sand remaining on the inner wall of the pickling section 102, thereby improving the pickling and purification effect of the quartz sand.

[0034] Meanwhile, the mass ring 303 in the upper flushing ring 301 slides away from the flushing hole 302 along the flushing ring 301. As the pickling tank 1 rotates from horizontal to vertical, the downward sliding speed of the mass ring 303 gradually increases. The mass ring 303 drives the auxiliary rod 407 to slide along the receiving cavity 404. The auxiliary rod 407 drives the top rod 408 to gradually slide away from the flushing hole 302. At this time, one end of the top rod 408 no longer presses the first push block 405. Under the action of the elastic element 409, the elastic element 409 drives the adjusting ring 401 to rotate through the first push block 405, so that the adjusting ring 401 drives the first adjusting hole 402 to no longer communicate with the flushing hole 302.

[0035] When the other end of the push rod 408 gradually presses against the second push block 406, the push rod 408 can drive the adjusting ring 401 to rotate along the flushing ring 301 through the inclined surface of the second push block 406. The elastic element 409 is compressed, and the adjusting ring 401 drives the second adjusting hole 403 to gradually connect with the flushing hole 302. A filter screen is provided in the flushing hole 302 to prevent quartz sand from flowing into the flushing ring 301 with the pickling solution. When the mass ring 303 slides away from the flushing hole 302, the mass ring... The pickling solution is drawn into the rinsing ring 301 through the second regulating hole 403 and the rinsing hole 302 and stored in the rinsing ring 301. As the pickling tank 1 continues to rotate, the above movement is repeated. Under the action of the mass ring 303, the pickling solution can be stored in the rinsing ring 301 and can also be squeezed out under pressure, thereby rinsing the side wall of the pickling section 102, avoiding the quartz sand residue on the side wall, and also facilitating the complete removal of the quartz sand in the pickling section 102.

[0036] In summary, through the coordinated arrangement of the mass ring 303, adjusting ring 401, flushing hole 302, first push block 405, and second push block 406, during the continuous rotation of the pickling tank 1, not only can the pickling solution be stored in the flushing ring 301 through the flushing hole 302 and the second adjusting hole 403, but the pickling solution in the flushing ring 301 can also be pressurized and squeezed out through the first adjusting hole 402 and the flushing hole 302 by the gravitational potential energy of the mass ring 303. This allows the pickling solution to flush the residual quartz sand on the pickling section 102, reducing the occurrence of residue problems. At the same time, the pressurized and squeezed-out pickling solution can also improve the effect of mixed pickling of quartz sand and ensure that the quartz sand is completely cleaned out of the pickling section 102, thus improving the efficiency and quality of pickling and purifying quartz sand. Example

[0037] This embodiment also provides a method for purifying high-purity quartz sand, including the following steps: S1: First, the quartz sand is fed into the pickling tank 1 through the feeding component 7, and the pickling liquid is pumped into the pickling tank 1 through the acid pumping component 6. Then, the pickling tank 1 is rotated to perform mixed pickling. S2: Then, acid is pumped into the pickling section 102 through the separating component 5 and the acid pumping component 6, and the acid in the upper pickling section 102 flows into the lower pickling section 102 through the feeding component 7 for pickling again. S3: Next, the side wall of the pickling section 102 is rinsed by the rinsing component 3, which can also impact the quartz sand to a certain extent and improve the pickling effect. S4: Finally, open the control valve 104 on the lower pickling section 102 so that the rinsing assembly 3 rinses the residual quartz sand on the side wall of the pickling section 102, thus preventing quartz sand from remaining on the side wall of the pickling section 102.
