Description

Technical Field

[0001] The present application relates to the technical field of quartz sand pickling equipment, and in particular to a quartz sand purification pickling equipment. Background Art

[0002] High-purity quartz sand, with its unique physical and chemical properties, plays a vital role in the fields of aviation, aerospace, electronics, and machinery. The stability of its inherent molecular chain structure, the superiority of its crystal morphology, and the regularity of its lattice changes give it high-temperature resistance, a low coefficient of thermal expansion, excellent insulation, strong corrosion resistance, significant piezoelectric and resonance effects, and extraordinary optical properties. These characteristics are increasingly prominent in numerous high-tech product applications.

[0003] Quartz sand purification primarily relies on pickling technology, which utilizes acid to chemically react with iron oxides and other impurities in the sand, effectively separating the impurities from the sand and achieving purification. Currently, to improve pickling efficiency, pickling equipment generally utilizes a stirring and mixing method. The specific operating process is as follows: the pickling solution and quartz sand are added to a reaction tank, and stirring is used to promote contact and reaction between the sand and the pickling solution, completing the entire pickling and purification process.

[0004] However, since each pickling step requires another water rinse, the pickling solution must be drained after pickling. Due to the large volume of pickling solution, draining the solution takes a long time, resulting in a waste of time. Furthermore, due to its high density, quartz sand tends to settle at the bottom of the reaction tank, making it difficult to distribute evenly during stirring. This can cause some quartz sand to be pickled prematurely. If the pickled sand is not promptly drained, it will not only cause over-pickling but also occupy space in the reaction tank, indirectly reducing overall pickling efficiency.

[0023] The quartz sand purification and pickling equipment according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, the quartz sand purification pickling equipment of the embodiment of the present application may include a pickling tank 1, a rotating drum 2, a feeding component 3, multiple dispersion components 4, an immersion tank 5, a pushing component 6 and a discharge component 7.

[0025] The rotating drum 2 is rotatably arranged inside the pickling tank 1 , and a plurality of partitioning mesh plates 9 are provided on the inner wall of the rotating drum 2 , which divide the rotating drum 2 into a plurality of spaces.

[0026] It should be noted that the drum 2 is a cylindrical hollow structure, and the curved surface of the drum 2 is a mesh structure. A bearing is provided inside the pickling tank 1, and the drum 2 is connected to the inner wall of the bearing. A drive shaft 17 is provided on one side of the drum 2. The drive shaft 17 extends to the outside of the pickling tank 1, and the drive shaft 17 is connected to an external drive motor, which can drive the drum 2 to rotate slowly through the motor.

[0027] Furthermore, the pickling tank 1 is provided with a heating module and a temperature control module. The heating module is connected to the temperature control module. The pickling tank 1 can be heated and heated by the heating module to accelerate the pickling effect and speed. The temperature control module can control the temperature in the pickling tank 1 to be constant.

[0028] In the embodiment of the present application, the partition mesh plate 9 can move the quartz sand in the pickling tank 1 to prevent the quartz sand from agglomerating, thereby allowing the quartz sand to fully contact with the pickling liquid, thereby improving the effect and efficiency of pickling.

[0029] A feed pipe 10 is connected to the pickling tank 1, and a delivery pipe 11 is provided inside the rotating drum 2. One end of the delivery pipe 11 passes through the rotating drum 2 and is connected to the feed pipe 10, and a plurality of feed ports 110 are provided at the bottom of the delivery pipe 11. The feeding assembly 3 is arranged inside the delivery pipe 11.

[0030] It should be noted that the feeding pipe 10 described in this embodiment is arranged at an angle, and a hopper 12 is connected to the top of the feeding pipe 10 . Quartz sand is placed in the hopper 12 and is fed into the conveying pipe 11 through the feeding pipe 10 .

[0031] Furthermore, the conveying pipe 11 is arranged inside the rotating drum 2, and the conveying pipe 11 is coaxially arranged with the rotating drum 2. When the feeding pipe 10 feeds the quartz sand into one end of the conveying pipe 11, the feeding assembly 3 can transport the quartz sand in the conveying pipe 11 to the interior of the rotating drum 2 and enter the interior of the rotating drum 2 through the feeding port 110.

[0032] Multiple dispersion components 4 are respectively arranged in corresponding spaces, and multiple dispersion components 4 are respectively connected to transmission components 8. A soaking tank 5 is provided below the rotating drum 2, and the bottom of the soaking tank 5 is inclined. The pushing component 6 is arranged in the soaking tank 5, and the discharge component 7 is arranged inside the pickling tank 1, and the discharge component 7 is connected to the soaking tank 5.

[0033] In the embodiment of the present application, the dispersion component 4 can disperse the quartz sand inside the drum 2 to prevent the quartz sand from agglomerating, thereby increasing the pickling speed of the quartz sand.

[0034] Furthermore, the soaking tank 5 has a mesh structure on the side wall and a plate structure on the bottom. The quartz sand particles will become smaller after pickling, so they will pass through the holes on the rotating drum 2 into the interior of the soaking tank 5, and slide along the inclined surface of the soaking tank 5 to a lower position. The pickled quartz sand is pushed into the discharge component 7 by the pushing component 6 and discharged through the discharge component 7.

[0035] A flushing tank 13 is provided on the side wall of the pickling tank 1, and a conveyor belt 14 is provided obliquely in the flushing tank 13. The conveyor belt 14 is located below the discharge port 15 of the discharge assembly 7. A support plate 18 is provided on the side wall of the flushing tank 13. A water pipe 19 is installed on the support plate 18. A plurality of nozzles 20 are connected to the water pipe 19, and the nozzles 20 are located above the conveyor belt 14.

[0036] It should be noted that a cleaning liquid is provided inside the flushing tank 13, the lower end of the conveyor belt 14 is located inside the cleaning liquid, and the higher end of the conveyor belt 14 is located above the cleaning liquid. A baffle 21 is provided on the conveyor belt 14, and the baffle 21 can block the quartz sand to prevent the quartz sand from sliding off the conveyor belt 14. The nozzle 20 is a high-pressure nozzle for flushing the quartz sand on the conveyor belt 14.

[0037] In the embodiment of the present application, the discharge assembly 7 can transport the pickled quartz sand to the conveyor belt 14 and transport it out through the conveyor belt 14.

[0038] In one embodiment of the present application, Figure 2 As shown, the feeding assembly 3 may include a first rotating shaft 30 and a first spiral blade 31 , wherein the first rotating shaft 30 is rotatably disposed inside the conveying pipe 11 , and the first spiral blade 31 is disposed on the first rotating shaft 30 .

[0039] It should be noted that the first spiral blade 31 described in this embodiment has multiple mesh holes evenly distributed on it, and the diameter of the mesh holes is smaller than the diameter of the quartz sand to be pickled. The first spiral blade 31 can transport the quartz sand to various positions of the conveying pipe 11 without causing a large flow of the pickling liquid.

[0040] In one embodiment of the present application, Figure 3 As shown, the dispersion assembly 4 may include a support shaft 40 and a plurality of scattering rods 41, wherein the support shaft 40 is rotatably connected to the rotating drum 2, and the plurality of scattering rods 41 are evenly distributed on the support shaft 40, and the scattering rods 41 are in a "V" shape.

[0041] In an embodiment of the present application, the scattering rod 41 located below the feed port 110 can disperse the quartz sand to prevent the quartz sand from gathering in the same position, and during the rotation of the drum 2, the scattering rod 41 can also disperse the quartz sand, further improving the pickling effect of the quartz sand.

[0042] Further, if Figure 4 As shown, the transmission assembly 8 may include a plurality of gears 80 and a gear ring 81, wherein a protective cover 16 is provided inside the pickling tank 1, one end of the support shaft 40 passes through the side wall of the rotating drum 2 and extends to the interior of the protective cover 16, a plurality of gears 80 are respectively arranged on the corresponding support shafts 40, the gear ring 81 is arranged inside the protective cover 16, and the gear ring 81 is meshed with the support shaft 40.

[0043] It should be noted that the multiple gears 80 and gear rings 81 described in this embodiment are all arranged inside the protective cover 16. The protective cover 16 can protect the gears 80 and gear rings 81 to prevent the gears 80 and gear rings 81 from being corroded by acid. The rotating drum 2 is rotatably connected to the protective cover 16. When the rotating drum 2 drives the support shaft 40 to rotate, the gear 80 rotates with the support shaft 40, and through the cooperation of the gear ring 81, the gear 80 can also rotate on its own, and drive the support shaft 40 and the loosening rod 41 to rotate, thereby finally realizing the stirring of the quartz sand.

[0044] In one embodiment of the present application, Figure 3 As shown, the pushing assembly 6 may include a ball screw 60, two nut sliders 61 and two pushing plates 62, wherein the ball screw 60 is rotatably arranged inside the immersion tank 5, the two nut sliders 61 are respectively mounted on the ball screw 60, and the two pushing plates 62 are respectively connected to the corresponding nut sliders 61.

[0045] It should be noted that the ball screw 60 described in this embodiment is connected to an external drive motor, which can drive the ball screw 60 to rotate, and the ball screw 60 is provided with two sections of threads in opposite directions, and the two nut sliders 61 are respectively arranged on different sections of threads. When the ball screw 60 rotates, it can drive the two nut sliders 61 to move toward or away from each other, and then push the quartz sand inside the immersion tank 5 to the middle position through the pushing plate 62.

[0046] Furthermore, the push plate 62 is fitted with the bottom and side walls of the immersion tank 5. The push plate 62 is a mesh structure, and the mesh diameter on the push plate 62 is smaller than the diameter of the quartz sand after pickling. During the movement of the push plate 62, the resistance of the mesh structure is small.

[0047] In one embodiment of the present application, Figure 3 As shown, the discharge assembly 7 may include a discharge cylinder 70, a second rotating shaft 71 and a second spiral blade 72, wherein the discharge cylinder 70 is arranged inside the pickling tank 1, and the discharge cylinder 70 is connected to the immersion tank 5, the second rotating shaft 71 is rotatably arranged inside the discharge cylinder 70, and the second spiral blade 72 is arranged on the second rotating shaft 71.

[0048] It should be noted that the discharge barrel 70 is located below the center of the pickling tank 1, and a plurality of mesh holes are evenly distributed on the second spiral blade 72, and the diameter of the mesh holes is smaller than the diameter of the quartz sand after pickling. The discharge barrel 70 is arranged at an angle, and the discharge port 15 is arranged at the higher end of the discharge barrel 70, and the discharge port 15 is located above the acid liquid, so that the quartz sand can be transported alone without bringing out the acid liquid.

[0049] Specifically, when pickling quartz sand, relevant personnel put the quartz sand into the hopper 12. Under the action of gravity, the quartz sand slides along the feed pipe 10 to one end of the conveying pipe 11. At this time, the relevant personnel control the first rotating shaft 30 to rotate, and the first rotating shaft 30 drives the first spiral blade 31 to rotate. The first spiral blade 31 can transport the quartz sand to the inside of the conveying pipe 11 and enter the inside of the rotating drum 2 through the feed port 110. Under the action of the dispersing rod 41, the quartz sand can be dispersed more evenly inside the rotating drum 2. At the same time, the relevant personnel control the drive shaft 17 to rotate, and the drive shaft 17 drives the rotating drum 2 and the partition mesh plate 9 to rotate slowly. Through the cooperation of the partition mesh plate 9 and the rotating drum 2, the quartz sand can be driven to roll, so that the quartz sand is fully in contact with the pickling liquid, thereby improving the effect and efficiency of pickling.

[0050] During the rotation of the drum 2, the transmission assembly 8 cooperates to drive the support shaft 40 and the spreading rod 41 to rotate, so as to spread the quartz sand and avoid the aggregation of the quartz sand, thereby further improving the pickling effect.

[0051] After the quartz sand comes into contact with the pickling liquid, impurities such as iron oxides, other oxides, yellow skin, water rust and organic chromosomes in the quartz sand can react with the pickling liquid to generate soluble salts, thereby removing these impurities from the quartz sand and achieving the purpose of purification. At the same time, after pickling, the quartz sand particles become smaller and will enter the interior of the immersion tank 5 through the mesh of the rotating drum 2.

[0052] Then, the relevant personnel controls the rotation of the ball screw 60, and the ball screw 60 drives the two pushing plates 62 to move toward each other, thereby pushing the quartz sand at the bottom of the immersion tank 5 to the center of the immersion tank 5, and finally falls into the discharge barrel 70, and the quartz sand after pickling is transported to the conveyor belt 14 through the second spiral blade 72. After soaking and washing, it is rinsed with clean water to completely remove the acid on the quartz sand, so that the quartz sand after pickling can be discharged in time to avoid excessive pickling, and also make room for the rotating drum 2 to facilitate the continued transportation of quartz sand to be pickled into the rotating drum 2, thereby realizing continuous pickling.

[0053] In summary, the quartz sand purification and pickling equipment of the present embodiment can continuously pickle quartz sand without interrupting to drain the pickling solution, thereby saving the time required for draining the solution. Furthermore, it can promptly discharge the pickled quartz sand, effectively preventing over-pickling and significantly improving the overall efficiency of quartz sand pickling.
