Description

Technical Field

[0001] This utility model relates to the field of quartz sand acid leaching technology, specifically to an acid leaching treatment device for quartz sand. Background Technology

[0002] Quartz sand acid leaching technology is a key process for deep purification of quartz sand. It utilizes acidic solutions to chemically react with impurities and minerals on the surface and in the crystal lattice of quartz sand, converting them into soluble salts which are then removed by washing. This technology significantly improves the purity of quartz sand by dissolving metal oxides such as iron, aluminum, and titanium, as well as silicate impurities, meeting the stringent requirements for raw materials in high-end fields such as photovoltaic glass, semiconductors, and high-purity quartz crucibles. The core process includes pretreatment, acid leaching, washing, neutralization, and drying. Pretreatment involves water washing to remove muddy impurities. The acid leaching stage uses hydrochloric acid, hydrofluoric acid, or a mixed acid system, and the reaction is accelerated under heating conditions. For example, hydrochloric acid reacts with iron impurities in quartz sand to form soluble ferric chloride, and hydrofluoric acid can dissolve the surface silica layer to remove inclusions. The washing stage requires repeated rinsing with deionized water until neutral to avoid residual acid affecting product quality. The neutralization treatment uses dilute alkaline solution to adjust the pH value and prevent acidic wastewater from polluting the environment.

[0003] In existing quartz sand acid leaching equipment, the acid leaching solution and quartz sand are prone to forming local dead zones, causing the quartz sand to deposit at the bottom of the equipment. This results in insufficient contact between the quartz sand and the acid solution, leading to low reaction efficiency, limiting the dissolution rate of impurities, and consequently affecting the overall purification efficiency. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the scheme of this application:

[0015] 1. To address the problems of blind spots, poor mixing effect, and low reaction rate in the existing technology of acid leaching treatment of quartz sand, this application proposes a stirring structure in which a drive motor drives a spiral stirring blade to rotate, and the spiral stirring blade drives the fixed frame and drive gear to rotate along the gear ring. This causes the stirring rod on the rotating rod to rotate on its own axis while revolving around the inside of the treatment tank. This unique design allows the spiral stirring blade and multiple stirring rods to work together, covering all areas of the treatment tank, effectively reducing the stirring blind spot, greatly improving the mixing effect of quartz sand and acid, accelerating the acid leaching reaction process, increasing the reaction rate, and ensuring the treatment quality and efficiency.

[0016] 2. To address the problems of material accumulation, low filtration efficiency, and poor performance in existing filtration technologies, this application proposes a filter frame and related material feeding mechanism. The treated material flows into the filter screen within the filter frame, while the acid leaching solution flows out through the filter screen and is discharged from the discharge pipe. The installation motor is activated, and through the connecting rod, first bevel gear, and second bevel gear, the lead screw rotates within the guide sleeve, causing the installation rod to move. Simultaneously, the installation gear on the installation rod rotates along the rack, driving the material feeding frame to feed the material. This design ensures that the material is continuously agitated during filtration, preventing accumulation and allowing the acid leaching solution to pass through the filter screen more smoothly. This effectively improves filtration efficiency, enhances filtration performance, and ensures the smooth operation of subsequent processes. Attached Figure Description

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.

[0023] This utility model embodiment provides a quartz sand acid leaching treatment device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a processing tank 1, a support leg 2 fixedly connected to the bottom of the processing tank 1, a base 3 fixedly connected to the bottom of the support leg 2, a feed inlet 4 fixedly connected to the top outer wall of the processing tank 1, a stirring assembly 5 inside the processing tank 1, a filter assembly 7 on the top of the base 3, and a valve 6 fixedly connected to the bottom of the processing tank 1. The stirring assembly 5 includes a drive motor 501, which is fixed to the top of the processing tank 1. The output shaft of the drive motor 501 is fixedly connected to a spiral stirring blade 502 via a coupling. A fixing frame 503 is fixedly connected to the outer wall of the spiral stirring blade 502. A drive gear 504 is rotatably connected to the bottom of the fixing frame 503. A gear ring 505 is meshed with the outer wall of the drive gear 504. A rotating rod 506 is fixedly connected inside the drive gear 504. A stirring rod 507 is fixedly connected to the outer wall of rod 506. Quartz sand can be fed into the treatment tank 1 through the feed port 4. At this time, the quartz sand can be acid leaching inside the treatment tank 1. In addition, by starting the drive motor 501, the drive motor 501 can drive the spiral stirring blade 502 to rotate. The spiral stirring blade 502 can drive the fixed frame 503 to rotate. The fixed frame 503 can drive the drive gear 504 to rotate along the gear ring 505. The drive gear 504 can drive the stirring rod 507 on the rotating rod 506 to revolve around the inside of the treatment tank 1 during rotation. Thus, by relying on the stirring of the spiral stirring blade 502 and multiple stirring rods 507, the blind zone in the stirring process can be reduced, the mixing effect can be improved, and the reaction rate can be increased.

[0024] Further such as Figure 3 As shown, the fixed frame 503 forms a rotating structure with the rotating rod 506 through the drive gear 504, and there are three drive gears 504. The three drive gears 504 are evenly spaced at the bottom of the fixed frame 503, which strengthens the connection between the drive gear 504 and the rotating rod 506. This allows the fixed frame 503 to drive the rotating rod 506 on the drive gear 504 to perform circular motion when it rotates.

[0025] Further such as Figure 3As shown, the processing tank 1 forms a rotating structure with the gear ring 505 and the drive gear 504, and the outer wall of the drive gear 504 meshes with the inner wall of the gear ring 505. The outer wall of the gear ring 505 is fixed to the inner wall of the processing tank 1. Through the provided drive gear 504, the drive gear 504 can rotate along the gear ring 505 inside the processing tank 1.

[0026] Further such as Figure 3 As shown, the rotating rod 506 and the stirring rod 507 form a fixed structure, and there are multiple stirring rods 507. The multiple stirring rods 507 are evenly spaced on the outer wall of the rotating rod 506, which strengthens the connection between the rotating rod 506 and the stirring rods 507, so that the rotating rod 506 can drive the multiple stirring rods 507 to stir the material.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the filter assembly 7 includes a filter frame 701, which is fixed to the top of the base 3. A motor 702 is mounted on one side of the filter frame 701. The output end of the motor 702 is fixedly connected to a connecting rod 703 via a coupling. A first bevel gear 704 is fixedly connected to the outer wall of the connecting rod 703. A second bevel gear 705 is meshed with one side of the first bevel gear 704. A lead screw 706 is fixedly connected inside the second bevel gear 705. A guide sleeve 707 is threadedly connected to the outer wall of the lead screw 706. An installation rod 710 is rotatably connected inside the guide sleeve 707. An installation gear 708 is fixedly connected to the outer wall of the installation rod 710. A rack 709 is meshed with the bottom of the installation gear 708. A material feeding frame 711 is fixedly connected to the wall. A filter screen 712 is installed inside the filter frame 701. A discharge pipe 713 is fixedly connected to one side of the filter frame 701. When the installation motor 702 is started, it can drive the first bevel gear 704 to rotate via the connecting rod 703. The first bevel gear 704 can drive the second bevel gear 705 to rotate. The second bevel gear 705 can drive the lead screw 706 to rotate. The lead screw 706 can rotate within the guide sleeve 707. The installation rod 710 can move under the drive of the guide sleeve 707. At the same time, the installation rod 710 rotates along the rack 709 via the installation gear 708, which can drive the material feeding frame 711 to feed the material, thereby improving the filtration effect.

[0028] Further such as Figure 4As shown, the connecting rod 703 forms a meshing transmission structure with the first bevel gear 704 and the second bevel gear 705. The outer surface of the first bevel gear 704 is fitted with the outer surface of the second bevel gear 705, which strengthens the connection effect between the first bevel gear 704 and the second bevel gear 705. This allows the connecting rod 703 to drive the first bevel gear 704 and then drive the second bevel gear 705 to rotate.

[0029] Further such as Figure 4 As shown, the second bevel gear 705 forms a threaded transmission structure with the lead screw 706 and the guide sleeve 707. The outer diameter of the lead screw 706 matches the inner diameter of the guide sleeve 707, and the outer wall of the lead screw 706 fits against the inner wall of the guide sleeve 707, which enhances the connection between the lead screw 706 and the guide sleeve 707. This allows the second bevel gear 705 to rotate within the guide sleeve 707 by driving the lead screw 706, which facilitates the movement of the guide sleeve 707.

[0030] Further such as Figure 4 As shown, the mounting rod 710 forms a rotating structure with the rack 709 via the mounting gear 708, and the outer wall of the mounting gear 708 meshes with the top of the rack 709, which strengthens the connection between the mounting gear 708 and the rack 709, allowing the mounting gear 708 to rotate along the rack 709, which in turn drives the mounting rod 710 to rotate.

[0031] Working Principle: During use, quartz sand can be fed into the treatment tank 1 through the feed inlet 4. The quartz sand undergoes acid leaching treatment inside the treatment tank 1. Furthermore, by starting the drive motor 501, the drive motor 501 drives the spiral stirring blades 502 to rotate. The spiral stirring blades 502 drive the fixed frame 503 to rotate, which in turn drives the drive gear 504 to rotate along the gear ring 505. The drive gear 504 then drives the stirring rods 507 on the rotating rod 506 to revolve around the inside of the treatment tank 1. Through the stirring of the spiral stirring blades 502 and multiple stirring rods 507, blind spots in the stirring process are reduced, the mixing effect is improved, and the reaction rate is increased. The externally opening valve 6 allows the processed material to flow into the filter screen 712 inside the filter frame 701 for feeding, and allows the acid leaching solution to flow out from the filter screen 712 and be discharged through the discharge pipe 713. At the same time, starting the installation motor 702 can drive the first bevel gear 704 to rotate via the connecting rod 703, which in turn drives the second bevel gear 705 to rotate, which in turn drives the lead screw 706 to rotate. The lead screw 706 can rotate within the guide sleeve 707, allowing the installation rod 710 to move under the drive of the guide sleeve 707. Simultaneously, the installation rod 710 rotates along the rack 709 via the installation gear 708, which drives the material feeding frame 711 to feed the material, improving the filtration effect.
