[0002] Quartz sand plays an important role in the manufacture of non-metallic mineral products. Its characteristics such as high silicon dioxide (SiO2) content (usually exceeding 90%), chemical stability, high melting point and hardness make it a core raw material in many fields, such as glass, ceramics, refractory materials, artificial quartz stone, building materials, as well as chemical industry, machinery, metallurgy and other fields. With the continuous progress and innovation of technology, future demands will develop towards high purity (electronic grade), refinement (nano-scale powder) and environmental protection processes (such as low-energy smelting), promoting the technological upgrading of the non-metallic mineral products industry.

Detailed implementation manners

[0020] An electronically activated quartz sand purification device, as Figures 1-9 shown, includes a support base 1, and a double-cone rotary cylinder is rotatably connected to the support base 1; the double-cone rotary cylinder includes a connecting cylinder 5 rotatably connected to the support base 1, and conical cylinders 4 are detachably connected to both ends of the connecting cylinder 5; a discharge pipe 8 is provided on one of the conical cylinders 4, and a discharge valve 16 is provided on the discharge pipe 8; connecting flanges are provided at both ends of the connecting cylinder 5 and on the conical cylinders 4, and the connecting cylinder 5 and the conical cylinders 4 are connected by bolts passing through the connecting flanges.

[0021] Further, a main shaft 19 is rotatably connected inside the double-cone rotary cylinder. Stirring assemblies are provided at both ends of the main shaft 19 and are adapted to cooperate with the tapered portions at both ends of the double-cone rotary cylinder; each of the pair of stirring assemblies includes a plurality of stirring plates 20 evenly distributed along the circumference of the main shaft 19, and through holes 28 are evenly distributed on the plurality of stirring plates 20; a sleeve that rotates in the opposite direction as the main shaft 19 is sleeved on the main shaft 19, and a stirring paddle 21 is provided on the sleeve. The stirring paddle 21 is disposed between the tapered portions at both ends of the double-cone rotary cylinder.

[0022] When the present invention is in use, quartz sand is conveyed into the double-cone rotary cylinder, and strong acid solutions such as hydrofluoric acid and hydrochloric acid solutions are injected, causing the double-cone rotary cylinder to rotate along the support base 1. The quartz sand slides and mixes along the inner wall in the double-cone rotary cylinder together with the strong acid solution; at the same time, the main shaft 19 is rotated, and the main shaft 19 drives the stirring plates 20 to stir and mix the quartz sand and the strong acid solution, so that while the quartz sand and the strong acid solution are flipping and flowing in the double-cone rotary cylinder, they also perform circumferential flow, enabling three-dimensional mixing between the quartz sand and the strong acid solution; as the main shaft 19 rotates, the sleeve rotates in the direction opposite to the rotation direction of the main shaft 19, and the sleeve mixes the quartz sand and the strong acid solution through the stirring paddle 21 to improve the uniformity of the mixing of the quartz sand and the strong acid solution.

[0023] Further, as Figures 5-8 shown, mounting brackets 27 detachably connected to the connecting cylinder 5 are provided between the stirring paddle 21 and each of the pair of stirring assemblies. The main shaft 19 is rotatably connected to the mounting brackets 27; a mounting seat is provided inside the connecting cylinder 5. Mounting holes are provided on both the mounting seat and the mounting brackets 27, and the mounting seat and the mounting brackets 27 are connected by bolts passing through the mounting holes; sector-shaped material guiding plates 25 are fixedly connected to each of the pair of mounting brackets 27. The pair of material guiding plates 25 are coaxial with the connecting cylinder 5, and the diameters of the pair of material guiding plates 25 are both smaller than the diameter of the mounting brackets 27; the straight edges of the pair of material guiding plates 25 are parallel to the axis of rotation of the connecting cylinder 5, and the pair of material guiding plates 25 are symmetrically arranged along the axis of rotation of the connecting cylinder 5.

[0024] Since the diameter of the material guiding plate 25 is smaller than the diameter of the mounting bracket 27, two flow paths are formed between the material guiding plate 25 and the double-cone rotary cylinder. The sector-shaped edge of the material guiding plate 25 and the double-cone rotary cylinder form the first path, and the straight edge of the material guiding plate 25 and the double-cone rotary cylinder form the second path; in addition, the pair of material guiding plates 25 are symmetrically arranged along the axis of rotation of the double-cone rotary cylinder, so that the quartz sand and the strong acid solution flowing through the second path of one of the material guiding plates 25 can flow to the other material guiding plate 25 for further diversion under the rotation of the double-cone rotary cylinder, thereby improving the fluidity of the quartz sand and the strong acid solution in the double-cone rotary cylinder; during the process of the quartz sand and the strong acid solution flowing from one deflector to the other deflector 25, the stirring paddle 21 mixes the quartz sand and the strong acid solution.

[0025] Further, to improve the fluidity of quartz sand and strong acid solution on the material guiding plate 25, scraping plates 24 that cooperate with the material guiding plate 25 are fixedly connected to the stirring plates 20, and the other ends of the scraping plates 24 are fixedly connected to the main shaft 19. When the main shaft 19 rotates, the main shaft 19 drives the scraping plates 24 to rotate, and the scraping plates 24 drive the quartz sand and strong acid solution on the material guiding plate 25 to flow.

[0026] Further, stabilizing rings 26 are provided at both ends of the stirring plate 20, and both ends of several stirring plates are fixedly connected to the stabilizing rings 26. The two ends of the stirring plate 20 are connected by the stabilizing rings 26 to improve the stability of the stirring plate 20 during rotation. Several stirring plates 20 are all inclined and aligned with the inclination angle of the conical cylinder 4.

[0027] Further, as Figure 6 and Figure 9 shown, a stirring motor 9 is fixedly connected to the support base 1, the output end of the stirring motor 9 is fixedly connected to a driving shaft 23, and the driving shaft 23 penetrates through the following driving rotating cylinder. A driving bevel gear 29 is fixedly connected to the driving shaft 23, a first driven bevel gear 30 is engaged with the driving bevel gear 29, and the first driven bevel gear 30 is fixedly connected to the sleeve. A second driven bevel gear 31 is also engaged with the driving bevel gear 29, and the second driven bevel gear 31 is fixedly connected to the main shaft 19.

[0028] When the main shaft 19 and the sleeve need to rotate, start the stirring motor 9, and the stirring motor 9 drives the driving shaft 23 to rotate. The driving shaft 23 drives the driving bevel gear 29 to rotate, the driving bevel gear 29 drives the sleeve to rotate through the first driven bevel gear 30, and the driving bevel gear 29 drives the main shaft 19 to rotate through the second driven bevel gear 31. As Figure 9 shown, the first driven bevel gear 30 and the second driven bevel gear 31 are symmetrically arranged. When the driving bevel gear 29 rotates, the first driven bevel gear 30 and the second driven bevel gear 31 rotate coaxially in opposite directions.

[0029] Further, a flipping motor 10 is fixedly connected to the support base 1, and the output end of the flipping motor 10 is fixedly connected to a driving sprocket. A driving rotating cylinder is fixedly connected to the connecting cylinder 5, a driven sprocket 15 that cooperates with the driving sprocket is fixedly connected to the driving rotating cylinder, and a chain that cooperates with the driven sprocket 15 is provided on the driving sprocket.

[0030] When the double-cone rotary cylinder needs to rotate, start the flipping motor 10, and the flipping motor 10 drives the driving sprocket to rotate. The driving sprocket drives the driven sprocket 15 to rotate through the chain, the driven sprocket 15 drives the connecting cylinder 5 to rotate through the driving rotating cylinder, and the connecting cylinder 5 drives the conical cylinder 4 to rotate.

[0031] Further, as Figure 2 and Figure 4As shown in the figure, a feeding rotary cylinder 14 that rotates with the support base 1 is fixedly connected to the connecting cylinder 5, and a feeding cylinder 7 that penetrates through the feeding rotary cylinder 14 is fixedly connected to the support base 1; a feeding pipe 11 is provided on the feeding cylinder 7, and a feeding hole 18 corresponding to the inside of the connecting cylinder 5 is also provided on the feeding cylinder 7; a liquid inlet pipe corresponding to the feeding hole 18 is further provided on the feeding cylinder 7, and a water inlet pipe 13 and an acid inlet pipe 12 are connected to the liquid inlet pipe; a feeding motor 6 is fixedly connected to the feeding cylinder 7, and a propeller 17 that cooperates with the feeding cylinder 7 is fixedly connected to the output end of the feeding motor 6.

[0032] When strong acid solution and clear water are being fed, the strong acid solution and clear water respectively flow into the feeding cylinder 7 through the acid inlet pipe 12 and the water inlet pipe 13 via the liquid inlet pipe, and then flow into the connecting cylinder 5 through the feeding hole 18 on the feeding cylinder 7; when quartz sand is being fed, the quartz sand flows into the feeding cylinder 7 through the feeding pipe 11. The feeding motor 6 is started, and the feeding motor 6 drives the propeller 17 to rotate. The propeller 17 drives the quartz sand to flow into the connecting cylinder 5 through the feeding hole 18.

[0033] Further, a pair of drain pipes 2 respectively corresponding to the acid inlet pipe 12 and the water inlet pipe 13 are provided on the other conical cylinder 4, and drain valves 3 are provided on the drain pipes 2; a filter screen 22 corresponding to the drain pipes 2 is provided on the conical cylinder 4; through the arrangement of the filter screen 22 and the pair of drain pipes 2, the strong acid solution and clear water can be automatically discharged respectively through the pair of drain pipes 2 under the action of the filter screen 22, improving the convenience of this application.

[0034] As Figures 1 to 9 shown, the working process of the present invention will be specifically explained below.

[0035] When the present invention is in use, the pickling process is as follows: Quartz sand flows into the feeding cylinder 7 through the feeding pipe 11. The feeding motor 6 is started, and the feeding motor 6 drives the propeller 17 to rotate. The propeller 17 drives the quartz sand to flow into the connecting cylinder 5 through the feeding hole 18; the strong acid solution flows into the feeding cylinder 7 through the acid inlet pipe 12 via the liquid inlet pipe, and then flows into the connecting cylinder 5 through the feeding hole 18 on the feeding cylinder 7.

[0036] The turning motor 10 is started, and the turning motor 10 drives the driving sprocket to rotate; the driving sprocket drives the driven sprocket 15 to rotate through the chain, the driven sprocket 15 drives the connecting cylinder 5 to rotate through the driving rotary cylinder, the connecting cylinder 5 drives the conical cylinder 4 to rotate, and the quartz sand slides and mixes along the inner wall in the double-cone rotary cylinder composed of the connecting cylinder 5 and the conical cylinder 4 together with the strong acid solution.

[0037] Meanwhile, start the stirring motor 9. The stirring motor 9 drives the drive shaft 23 to rotate. The drive shaft 23 drives the driving bevel gear 29 to rotate. The driving bevel gear 29 drives the sleeve to rotate through the first driven bevel gear 30, and the driving bevel gear 29 drives the main shaft 19 to rotate through the second driven bevel gear 31. The main shaft 19 drives the stirring plate 20 to stir and mix the quartz sand and the strong acid solution, so that while the quartz sand and the strong acid solution are tumbling and flowing in the double-cone rotary drum, they also flow in a circular motion, enabling a three-dimensional mixing between the quartz sand and the strong acid solution.

[0038] Due to the arrangement of a pair of guide plates 25, since the diameter of the guide plate 25 is smaller than that of the mounting bracket 27, the guide plate 25 and the double-cone rotary drum form two flow paths. The fan-shaped edge of the guide plate 25 and the double-cone rotary drum form the first path, and the straight edge of the guide plate 25 and the double-cone rotary drum form the second path. Another pair of guide plates 25 are symmetrically arranged along the axis of rotation of the double-cone rotary drum, so that the quartz sand and the strong acid solution flowing through the second path of one of the guide plates 25 can flow onto another guide plate 25 for further diversion under the rotation of the double-cone rotary drum, thereby improving the fluidity of the quartz sand and the strong acid solution in the double-cone rotary drum. During the process of the quartz sand and the strong acid solution flowing from one guide plate to another guide plate 25, the sleeve drives the stirring paddle 21 to mix the quartz sand and the strong acid solution in a mixed flow.

[0039] After pickling, open the drain valve 3 to allow the strong acid solution to flow out through the filter screen 22 and the drain pipe 2. After the strong acid solution is discharged, let the clear water flow into the feeding cylinder 7 through the inlet pipe 13 via the liquid inlet pipe, and then flow into the connecting cylinder 5 through the feeding hole 18 on the feeding cylinder 7. Under the action of the stirring plate 20, the stirring paddle 21, and the guide plate 25, the clear water is used to wash the quartz sand. After the quartz sand is washed, the clear water is discharged through the drain pipe 2.

[0040] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: 1. When the present invention is in use, through the coordinated setting of the main shaft 19, the stirring plate 20 and the double-cone rotary drum, while the quartz sand and the strong acid solution slide and mix along the inner wall in the double-cone rotary drum, the main shaft 19 drives the stirring plate 20 to stir and mix the quartz sand and the strong acid solution, and they flow in a circular motion, enabling a three-dimensional mixing between the quartz sand and the strong acid solution, so as to improve the uniformity of the mixing of the quartz sand and the strong acid solution.

[0041] 2. When the present invention is in use, since the diameter of the material guiding plate 25 is smaller than the diameter of the mounting frame 27, two flow paths are formed by the material guiding plate 25 and the double-cone rotary drum. The fan-shaped edge of the material guiding plate 25 and the double-cone rotary drum form the first path, and the straight edge of the material guiding plate 25 and the double-cone rotary drum form the second path. When the double-cone rotary drum rotates, under the action of a pair of material guiding plates 25, the quartz sand and the strong acid solution flow between the first path and the second path of the pair of material guiding plates 25, and are dispersed and mixed under the action of the stirring paddle 21, so as to improve the fluidity of the quartz sand and the strong acid solution in the double-cone rotary drum.
