Description

Technical Field

[0001] This invention relates to the field of quartz sand purification and processing technology, specifically to an acid washing device and method for purifying high-purity quartz sand. Background Technology

[0002] In certain industrial sectors, extremely high purity requirements are placed on quartz sand. Natural quartz sand contains not only clay, biological and organic impurities, but also a significant amount of metal oxide impurities, primarily iron oxide, which often form water rust on the surface. While metal oxides can be removed through acid chemical reactions, impurities such as clay still affect the pickling effect. A quartz sand purification and pickling device (application number 2023109118826) addresses this issue. It includes an pickling tank for immersing and pickling quartz sand and a pretreatment device mounted above the pickling tank for pretreatment before pickling. This device enables simultaneous impurity removal pretreatment before quartz sand pickling and purification, achieving continuous pretreatment processing, improving pretreatment efficiency, and ensuring the pickling effect.

[0003] Although this device has the advantages mentioned above, it still has the following drawbacks in use:

[0004] 1) Although the device removes impurities such as clay through pretreatment, the drying effect is poor due to the stacking of materials, and the crowded internal structure results in a small drying volume, thus making the pretreatment efficiency low.

[0005] 2) Although the device can separate impurities such as clay through pretreatment, the dried quartz sand and clay impurities are not easy to screen, which can easily affect the pickling or drying process.

[0006] Therefore, it is necessary to address the aforementioned problems. Summary of the Invention

[0019] Beneficial effects

[0020] This invention provides an acid washing device and method for purifying high-purity quartz sand. Compared with the prior art, it has the following advantages:

[0022] (2) By setting up a pretreatment component, before drying and removing impurities, the impurities that can be easily separated on the quartz sand are removed by the impact of falling material, and the sieve is screened by wind power, which further improves the efficiency of drying and separation.

[0023] (3) By setting up a sealing component, the linear motor drives the filter screen to seal the inside of the hopper. Through the action of multiple filter screens with different filter hole diameters, it is easy to prevent the leakage of raw materials during drying and to facilitate the separation of impurities and quartz sand after drying.

[0024] (4) By setting up structures such as rings, the contact between the sliding block and the rotating block, as well as the extension and retraction of the output end of the spring rod, the impact plate can rotate in one direction when it contacts the quartz sand, so as to guide the quartz sand and impurities, so as to facilitate the screening of the two and the discharge of the quartz sand.

The inside of the dust box 332 is movably connected to the inside of the dust box 32. The outer surface of the dust box 332 is slidably connected to the body of the dust box 31.

[0052] By setting up a receiving unit 33, and adjusting the motor 336 to make the rack 334 drive the dust box 332 to move, the material inlet 333 is connected to the hopper 4 and the inside of the dust box 32 respectively, so that the impurities screened during pretreatment and the impurities filtered after drying can be received. At the same time, the connection between the gear 335 and the rack 334 facilitates the disassembly and assembly of the dust box 332, thereby facilitating the unified treatment of impurities.

[0053] Example 6: This example combines Examples 1 to 5. It utilizes impact force for pretreatment and separation, and uses wind power for sieving impurities. At the same time, it employs a planetary orbital processing method to facilitate continuous processing and uniform drying, thereby improving the drying effect and efficiency.

[0054] This invention also discloses an acid washing method for purifying high-purity quartz sand, specifically including the following steps:

[0055] Step 1: Quartz sand is added into the solid box 31 through the feed pipe 37. The dry clay is separated by the collision with the impact plate 35, and the movement of the impact plate 35 guides the quartz sand and impurities. The support rod 34 drives the rotating block 345 to follow suit. The contact between the curved surfaces of the rotating block 345 and the sliding block 344 compresses the output end of the spring rod 343, causing the impact plate 35 to rotate unidirectionally. The contact between the straight surfaces of the rotating block 345 and the sliding block 344 further contributes to this process. The contact is used to restrict the reverse rotation, and the blower 39 blows the dry clay and quartz sand to screen. The quartz sand enters the filter cylinder 2 through the guide plate 38 and the hopper 4. Then the linear motor 55 slides along the slide rail 56 and drives the filter screen 53 to move inside the hopper 4 through the baffle plate 54. The hopper 4 and the filter cylinder 2 are sealed. At the same time, the filter screen 53 stretches the drum 57 to rotate, which compresses the spring or torsion spring. The dust enters the dust box 332 through the dust box 32 and the material port 333.

[0056] Step 2: The heating rod 7 is energized to heat and dry the quartz sand in the filter cylinder 2. At the same time, the feeding motor 15 drives the fixed plate 11 and the sliding plate 13 to rotate, which moves the quartz sand to dry it and separate the dust. Meanwhile, the output end of the rotating motor 8 rotates in the opposite direction and drives the filter cylinder 2 to rotate through the circular plate 6 to load materials in sequence.

[0057] Step 3: After drying and dust removal, adjust motor 336 to drive dust box 332 to move, so that material inlet 333 is below hopper 4. Then, outer linear motor 55 resets, so that outer filter screen 53 is unwound from the complete seal inside hopper 4. Thus, through the filtering effect of inner filter screen 53, dust inside filter cartridge 2 enters dust box 332. After dust box 332 resets, inner linear motor 55 drives inner filter screen 53 to reset, and quartz sand falls into pickling tank 1 through hopper 4 for pickling.

6. An acid washing method for purifying high-purity quartz sand, characterized in that: The acid washing equipment for purifying high-purity quartz sand according to claim 5 specifically includes the following steps: Step 1: Quartz sand is added into the solid box (31) through the feed pipe (37). The dry clay is separated by the collision with the impact plate (35). At the same time, the quartz sand is screened by the blowing of the blower (39). The quartz sand enters the filter cartridge (2) through the guide plate (38) and the hopper (4), while the dust enters the dust box (332) through the dust box (32) and the material port (333). Step 2: The heating rod (7) is powered on to heat and dry the quartz sand in the filter cylinder (2). At the same time, the feeding motor (15) drives the fixed plate (11) and the sliding plate (13) to rotate, which moves the quartz sand to dry it and separate the dust. Meanwhile, the rotating motor (8) drives the filter cylinder (2) to rotate through the circular plate (6) to load the material in sequence. Step 3: After drying and dust removal, adjust the motor (336) to drive the dust box (332) to move, so that the material inlet (333) is below the hopper (4), so that the dust inside the filter cartridge (2) enters the dust box (332). Then, after the dust box (332) is reset, the quartz sand falls into the pickling tank (1) through the hopper (4) for pickling.
