Description

Technical Field

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

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries.

[0003] Before testing quartz, the submitted quartz samples often need to be processed. This involves physical crushing followed by magnetic separation. After magnetic separation, the quartz sand is purified by acid washing. However, current acid washing equipment does not screen the quartz sand according to its particle size before acid washing; instead, it soaks the quartz sand in a uniform concentration of mixed acid solution. Due to varying soaking times, over- or under-acid washing can easily occur. Furthermore, during acid washing, the mixed acid solution is usually pre-poured into the acid washing tank before the quartz sand is added. This method causes quartz sand to accumulate, preventing some sand from fully contacting the mixed acid solution, resulting in incomplete acid washing and reduced purification quality. Therefore, to address these shortcomings, this invention makes the following improvements. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] This invention provides a purification apparatus for high-purity quartz sand. It has the following beneficial effects:

[0019] (1) The purification device for high-purity quartz sand can screen and classify the pretreated quartz sand, which is convenient for subsequent acid washing with mixed acid solutions of different concentrations. Large-particle quartz sand is suitable for high-concentration mixed acid solutions, while small-particle quartz sand is suitable for low-concentration mixed acid solutions. By distinguishing the two, the phenomenon of uneven acid washing effect can be avoided. At the same time, the quartz sand can be fully mixed in the mixed acid solution during the acid washing process. The injection of mixed acid solution and the feeding of quartz sand can be carried out simultaneously. Dynamic stirring is used to accelerate the acid washing efficiency and quality. Finally, the solid-liquid separation mechanism is used to realize the rapid separation of solid particles and waste liquid, which facilitates the acquisition of high-purity quartz sand.

[0020] (2) The purification device for high-purity quartz sand can screen the pretreated quartz sand by setting the feeding and dispersing mechanism and the screening holes, and classify it into large-particle quartz sand and small-particle quartz sand. As the cleaning brush rotates and moves to the surroundings, it can speed up the screening efficiency of quartz sand and avoid the phenomenon of some quartz sand particles clogging the screening holes.

[0021] (3) The purification device for high-purity quartz sand, through the setting of the connecting components, can prevent small particles of quartz sand from overflowing during the upward or downward movement of the protective cylinder, and plays a guiding role for the small particles of quartz sand.

[0022] (4) The purification device for high-purity quartz sand, through the setting of the solid-liquid separation mechanism, can realize the rapid separation of solid particles and waste liquid after the quartz sand has been acid-washed, thereby facilitating personnel to screen the acid-washed and purified quartz sand.

[0023] (5) The purification device for high-purity quartz sand, through the setting of the stirring mechanism, can mix and stir the mixed acid solution and quartz sand particles, so that the quartz sand is fully immersed in the mixed acid solution, so that the two are fully in contact, improving the pickling efficiency and quality, and avoiding the phenomenon of insufficient pickling caused by static pickling.

[0030] 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.

[0031] Example 1

[0032] Please see Figures 1 to 4 As shown, the present invention provides a purification device for high-purity quartz sand, including an acid washing tank. The acid washing tank includes an outer cylinder 1 and an inner cylinder 2. The top of the front of the outer cylinder 1 is connected to a liquid inlet pipe 9, and one end of the liquid inlet pipe 9 passes through the outer cylinder 1 and is connected to the surface of the inner cylinder 2. A screening cylinder 3 is fixedly installed on the top of the acid washing tank by a support frame. A pushing and dispersing mechanism 4 is provided inside the screening cylinder 3, and the pushing and dispersing mechanism 4 is used to accelerate the screening speed of quartz sand particles. An agitation mechanism 5 is provided inside the acid washing tank, and the agitation mechanism 5 is used to fully mix the quartz sand particles with the mixed acid solution. The bottom end of the screening cylinder 3 is connected to the top end of the inner cylinder 2 by a connecting component 6. A central plate 7 is provided in the middle of the screening cylinder 3. Screening holes 8 are opened inside the central plate 7 and at the bottom end of the screening cylinder 3. The diameter of the screening holes 8 inside the central plate 7 is smaller than the diameter of the screening holes 8 on the screening cylinder 3.

[0033] By screening and classifying the pretreated quartz sand, it is convenient to select mixed acid solutions of different concentrations for subsequent pickling. Large-particle quartz sand is suitable for high-concentration mixed acid solutions, while small-particle quartz sand is suitable for low-concentration mixed acid solutions. By separating the two, uneven pickling effect can be avoided. At the same time, the quartz sand can be fully mixed in the mixed acid solution during the pickling process. The injection of mixed acid solution and the feeding of quartz sand can be carried out simultaneously. Dynamic stirring is used to accelerate the pickling efficiency and quality. Finally, the solid-liquid separation mechanism 10 realizes the rapid separation of solid particles and waste liquid, which facilitates the acquisition of high-purity quartz sand.

[0034] Example 2

[0035] Based on Example 1, please refer to Figures 1 to 4As shown, the material pushing and dispersing mechanism 4 includes a motor 41 fixedly connected to the top of the screening cylinder 3 via a support frame. One end of the output shaft of the motor 41 is fixedly connected to a rotating rod 42 via a coupling. The bottom end of the rotating rod 42 is rotatably connected to the top of the center plate 7 via a bearing. A movable plate 43 is movably disposed on the surface of the rotating rod 42. A through groove is formed on the surface of the movable plate 43, and an inclined rod 44 is rotatably connected to the inside of the through groove via a rotating shaft. A telescopic rod 45 is fixedly disposed at the bottom of the surface of the rotating rod 42, and an arc-shaped push plate 47 is fixedly disposed at one end of the telescopic rod 45. The arc-shaped push plate 47... A cleaning brush 46 is fixedly installed at the bottom. The bottom end of the inclined rod 44 is rotatably connected to the top of the arc-shaped push plate 47 via a movable shaft. A T-shaped collar 48 is movably installed on the top of the movable plate 43 and on the surface of the rotating rod 42. A protrusion is provided on the inner wall of the T-shaped collar 48. A groove adapted to the protrusion is opened on the surface of the rotating rod 42. The surface of the protrusion is slidably connected to the inner wall of the groove. A first electric push rod 49 is installed inside the support frame. A U-shaped plate 410 is fixedly connected to the protruding end of the first electric push rod 49. The protrusion of the T-shaped collar 48 is located inside the U-shaped plate 410.

[0036] The protective cylinder 61 is controlled to rise along the screening cylinder 3 until its top surface is flush with the top surface of the screening cylinder 3. Pre-treated quartz sand is then placed inside the protective cylinder 61, landing on top of the central plate 7. The diameter of the screening holes 8 inside the central plate 7 is smaller than the diameter of the screening holes 8 on the screening cylinder 3, allowing smaller quartz sand particles to be discharged through the screening holes 8 on the central plate 7, while larger quartz sand particles are discharged through the screening holes 8 on the screening cylinder 3. During the discharge process, the motor 41 is started, causing the motor 41 to drive the rotating rod 42 to rotate. The rotating rod 42, through the protrusions and grooves, drives the T-shaped collar 48 to rotate. The movable plate 43, through the inclined rod 44, drives the arc-shaped push plate 47 to rotate synchronously. At this time, the cleaning brush 46 rotates, accelerating the quartz sand screening efficiency and preventing blockage inside the screening holes 8. After the small quartz sand particles inside the protective cylinder 61 are screened out, the protective cylinder 61 is controlled to descend to... Figure 2 In this state, only large-particle quartz sand remains in the screening cylinder 3. The first electric push rod 49 is activated, causing the extended end of the first electric push rod 49 to drive the T-shaped collar 48 downward through the U-shaped plate 410. At this time, the movable plate 43 moves synchronously along the rotating rod 42. With the rotation setting at both ends of the inclined rod 44, the four arc-shaped push plates 47 can drive the cleaning brush 46 to move around the center of the central plate 7. Combined with the rotation of the rotating rod 42, the large-particle quartz sand can be pushed over a large range, thereby accelerating the falling speed and facilitating material discharge.

An external agitator is disposed inside the outer cylinder 1, and an internal agitator is disposed inside the inner cylinder 2. The external agitator includes a connecting rod 52. One end of the connecting rod 52 is fixedly connected to the extended end of the first hydraulic cylinder 51, and the other end of the connecting rod 52 passes through the outer cylinder 1 and extends into the interior of the outer cylinder 1. A first stirrer 53 is fixedly disposed on the surface of the connecting rod 52 located inside the outer cylinder 1. An outer protective frame is slidably disposed on the surface of the inner cylinder 2, and a first annular magnet 54 is fixedly disposed inside the outer protective frame. One end of the connecting rod 52 located inside the outer cylinder 1 is fixedly connected to the surface of the outer protective frame. The internal agitator includes an inner protective frame slidably disposed on the inner wall of the inner cylinder 2, and a second annular magnet 55 is fixedly disposed inside the inner protective frame. The magnetic poles of the first annular magnet 54 and the second annular magnet 55 are opposite. A second stirrer 56 is fixedly disposed between the two sides of the inner wall of the inner protective frame through a crossbar.

[0039] During the quartz sand feeding process, a high-concentration mixed acid solution suitable for large-particle quartz sand is slowly poured into the outer cylinder 1, while a low-concentration mixed acid solution suitable for small-particle quartz sand is transported to the inner cylinder 2 through the inlet pipe 9 until a certain liquid level is reached. Then, the first hydraulic cylinder 51 is activated, causing the extended end of the first hydraulic cylinder 51 to move the outer protective frame up and down along the surface of the inner cylinder 2. At this time, due to the adsorption setting of the first annular magnet 54 and the second annular magnet 55, the inner protective frame moves up and down synchronously. During the up and down movement, the first agitator 53 and the second agitator 56 can stir the quartz sand inside the inner cylinder 2 and the outer cylinder 1, so that it is fully mixed with the mixed acid solution, thereby accelerating the pickling speed and quality.

[0040] Example 4

[0041] Please refer to Examples 1 to 3. Figure 1 and Figure 2As shown, a solid-liquid separation mechanism 10 is provided inside the outer cylinder 1.

A discharge valve 108 is fixedly installed inside the inner cylinder 2.

[0042] After the quartz sand pickling inside the pickling tank is completed, the second hydraulic cylinder 101 is activated, causing the extended end of the second hydraulic cylinder 101 to drive the L-shaped rod 102 downward. At this time, the L-shaped rod 102 drives the sealing seat 104 and the sealing plate 103 to move synchronously, so that the top of the sealing plate 103 releases the seal on the annular filter plate 109, and the sealing seat 104 moves down to release the seal on the filter hole 105. At this time, the waste liquid inside the outer cylinder 1 and the inner cylinder 2 is discharged through the annular filter plate 109 and the filter hole 105 respectively, and finally drained through the liquid outlet pipe 106. After the waste liquid is drained, the solenoid valve is opened, so that the solid particles inside the outer cylinder 1 are discharged through the discharge pipe 107, and the solid particles inside the inner cylinder 2 are discharged downward.

[0045] Activate the second electric push rod 63, so that the extended end of the second electric push rod 63 drives the protective cylinder 61 to move up or down through the fixed rod. During the movement of the protective cylinder 61, the small particles of quartz sand can always be discharged into the inner cylinder 2 through the setting of the telescopic tube 62 to prevent overflow.
