[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that in the prior art, the quartz sand is not preliminarily cleaned of metal impurities before formal pickling, resulting in the presence of a large amount of metal impurities in the quartz sand after pickling and the low purity of the quartz sand, the present invention provides an acid treatment device, which can realize magnetic adsorption and impurity removal of quartz sand before pickling, so as to improve the purity of the quartz sand after subsequent pickling.

[0020] It should be noted that the acid treatment device described in the present invention is used for but not limited to quartz sand, etc. For the convenience of explanation, in the present invention, only the application of the acid treatment device to quartz sand is used as an example for explanation, and the principle of the acid treatment device being applied to other types of equipment is substantially the same as that applied to quartz sand, which will not be repeated here.

[0021] See also Figure 1 , Figure 1 The structure diagram of the acid treatment device 100 in one embodiment of the present invention is shown in FIG. 1 . The acid treatment device 100 includes a reactor 1, a stirring assembly 2 and an adsorption assembly 3. The reactor 1 is provided with a feed inlet 11, a reaction chamber 12 and a discharge port 3 which are connected in sequence. The stirring assembly 2 includes a stirring member 21 and a stirring motor 22. The stirring member 21 is rotatably disposed in the reaction chamber 12. The stirring motor 22 is connected to the stirring member 21 and is used to drive the stirring member 21 to rotate so as to stir the quartz sand in the reaction chamber 12 so that the quartz sand is fully pickled. The adsorption assembly 3 includes a first magnetic disk 31. The first magnetic disk 31 is rotatably disposed in the reaction chamber 12 and is located between the feed inlet 11 and the stirring member 21. The first magnetic disk 31 is embedded with a magnetic plate. The first magnetic disk 31 can receive the quartz sand falling from the feed inlet 11 and magnetically absorb the metal impurities in the quartz sand through the magnetic plate so that the metal impurities are attached to the surface of the first magnetic disk 31. The first magnetic disk 31 can pour the quartz sand that has been metal-removed into the stirring member 21 when rotating, and the stirring member 21 stirs the quartz sand together with the acidic solution to fully mix the quartz sand and the acidic solution to fully remove impurities on the surface of the quartz sand. The first magnetic disk 31 of this embodiment first preliminarily adsorbs the metal impurities in the quartz sand, and after adsorbing a part of the metal impurities, the first magnetic disk 31 pours the quartz sand into the acidic solution, which can make the metal impurities more fully removed, and finally the quartz sand discharged from the discharge port 3 has a higher purity.

[0022] In one embodiment, see Figure 1 The acid treatment device 100 further includes a shaking component 4, which is disposed on the outer wall of the reactor 1 and can shake the first magnetic disk 31 to make the quartz sand in the first magnetic disk 31 spread out. In this embodiment, the quartz sand entering from the feed port 11 falls on the first magnetic disk 31 in a roughly hill shape, and the shaking component 4 spreads out the accumulated quartz sand by shaking the first magnetic disk 31, so that the first magnetic disk 31 can fully magnetically absorb the metal impurities in the quartz sand, and the initial impurity removal effect is more sufficient.

[0023] In one embodiment, see Figure 1The shaking assembly 4 includes a bracket 41, a turntable 42 and a cam 43. The bracket 41 is connected to the outer wall of the reactor 1, the turntable 42 is rotatably connected to the bracket 41, and the cam 43 is connected to the turntable 42, and can drive the first magnetic disk 31 to shake when the turntable 42 rotates. In this embodiment, the turntable 42 is driven to rotate continuously in one direction by a motor (not shown in the figure) connected thereto, so as to drive the cam 43 to cyclically drive the first magnetic disk 31 to shake. The shaking assembly 4 is located outside the reaction chamber 12 and does not occupy additional space in the reaction chamber 12, so that the reaction chamber 12 can accommodate more quartz sand, which is beneficial to improving the pickling efficiency of the quartz sand. In addition, this embodiment adopts the method of rotating the cam 43 to drive the first magnetic disk 31 to shake, which has a simple structure and stable movement.

[0024] In one embodiment, see Figure 2 The adsorption assembly 3 further includes an outer frame 32, a slide bar 33, a reset spring 34 and a driving rod 35. The outer frame 32 is hollow with openings at both ends and is rotatably connected to the cavity wall of the reaction chamber 12. Specifically, both ends of the outer frame 32 are provided with rotating shafts 321, and the outer frame 32 is rotatably connected to the cavity wall of the reaction chamber 12 through two rotating shafts 321. The outer frame 32 is also connected to the first magnetic disk 31. When the outer frame 32 rotates, it can drive the first magnetic disk 31 to flip so as to dump the quartz sand in the first magnetic disk 31. The slide bar 33 is arranged inside the outer frame 32, and the first magnetic disk 31 is slidably connected to the slide bar 33. The reset spring 34 is sleeved on the slide bar 33 and is located between the outer frame 32 and the first magnetic disk 31. One end of the driving rod 35 slides through the outer frame 32 and is connected to the first magnetic disk 31. The other end of the driving rod 35 can drive the first magnetic disk 31 to reciprocate when pressed by the cam 43. In this embodiment, a pressure plate 351 is provided at the end of the driving rod 35, and the area of ​​the pressure plate 351 is relatively large. The cam 43 can cyclically press the pressure plate 351 during the rotation process, driving the driving rod 35 to slide toward the first magnetic disk 31, driving the first magnetic disk 31 to slide along the slide rod 33, and under the action of the return springs 34 at both ends of the first magnetic disk 31, the first magnetic disk 31 can be driven to slide back and forth, thereby shaking the contained quartz sand, and the quartz sand is gradually spread on the first magnetic disk 31.

[0025] In one embodiment, see Figure 2 , a return spring 34 is provided between both ends of the first magnetic disk 31 and the outer frame 32. In this embodiment, two slide bars 33 are provided, and the two slide bars 33 are arranged in parallel inside the outer frame 32 at intervals. Both ends of the two slide bars 33 are provided with a return spring 34, and the number of the return springs 34 is four in total. When the driving rod 35 is pressed by the cam 43 and drives the first magnetic disk 31 to slide back and forth, the first magnetic disk 31 can press the four return springs 34 in a reciprocating cycle, and the four return springs 34 can accumulate and release elastic force, strengthen the shaking of the first magnetic disk 31, and can quickly spread the quartz sand in the first magnetic disk 31.

[0026] In one embodiment, see Figure 1 The acid treatment device 100 also includes a recovery component, which includes a recovery box 51, a recovery pipe 52 and a liquid pump 53. A recovery tank 511 is provided in the recovery box 51. The recovery tank 511 is located below the discharge port 13 and is used to receive the acid liquid flowing out of the discharge port 13. One end of the recovery pipe 52 is connected to the recovery tank 511, and the other end is close to the feed port 11. The liquid pump 53 is provided in the recovery pipe 52 and can suck the acid liquid in the recovery tank 511 when working. The acid liquid is then discharged from the other end of the recovery pipe 52 to the feed port 11 and flows back into the reaction chamber 12, so as to facilitate the recycling of the acid liquid.

[0027] In one embodiment, see Figure 2 The recovery component also includes a main controller (not shown in the figure) and a first liquid level sensor 54. The first liquid level sensor 54 is arranged on the inner wall of the recovery tank 511. The main controller is connected to the first liquid level sensor 54 and the liquid pump 53. When the liquid level of the recovery tank 511 reaches the first liquid level sensor 54, the first liquid level sensor 54 sends a control signal to the main controller, so that the main controller controls the liquid pump 53 to suck the acid liquid in the recovery tank 511 into the feed port 11.

[0028] In one embodiment, see Figure 1 The recovery component further includes a hopper 55, which is rotatably connected to the inner wall of the recovery tank 511. The hopper 55 is located directly below the discharge port 13 and is used to receive the acid liquid discharged from the discharge port 13. When the received acid liquid accumulates to a certain extent, the hopper 55 can rotate relative to the recovery box 51 to dump the acid liquid into the recovery tank 511. In this embodiment, by setting the hopper 55 to receive the acid liquid, since the hopper 55 has a large volume, the hopper 55 is usually rotated relative to the recovery box 51 when it is full of acid liquid to dump the acid liquid into the recovery tank 511, and more acid liquid can be added to the recovery tank 511 instantly. The liquid pump 53 can work intermittently, and the first liquid level sensor 54 can be set at the liquid level after the hopper 55 has poured out the acid liquid. The liquid pump 53 can also be connected to the main controller. When the hopper 55 has poured out the acid liquid, the liquid level of the recovery tank 511 just reaches the first liquid level sensor 54. The first liquid level sensor 54 sends a control signal to the main controller to control the liquid pump 53 to suck the acid liquid from the recovery tank 511. This is beneficial to saving energy, and the liquid pump 53 does not need to work all the time.

[0029] In the present embodiment, the second liquid level sensor 56 can also be set at the inner wall of the recovery tank 511, and the second liquid level sensor 56 is located below the first liquid level sensor 54, and the second liquid level sensor 56 is also connected to the main controller. As the liquid pump 53 continuously sucks the acid solution in the recovery tank 511, the acid solution in the recovery tank 511 gradually decreases. When the liquid level of the acid solution drops to below the second liquid level sensor 56, the second liquid level sensor 56 generates a corresponding sensing signal and is transmitted to the main controller, and the main controller controls the liquid pump 53 to suspend work, so as to realize the automatic control of the liquid pump 53 to work or not work.

[0030] In one embodiment, see Figure 1 , the recovery assembly also includes a heating element 57, the heating element 57 includes a connecting sleeve 571 and a heating wire 572, the connecting sleeve 571 is sleeved on the outer wall of the recovery pipe 52, and the heating wire 572 surrounds the connecting sleeve 571 and is used to heat the acid solution flowing through the connecting sleeve 571. In the present embodiment, the heating wire 572 only heats the acid solution flowing through the connecting sleeve 571, and the acid solution that does not flow through the connecting sleeve 571 is temporarily not heated, which is conducive to saving energy. In addition, the acid solution heated by the heating wire 572 can immediately flow into the reaction chamber 12 through the feed port 11 for utilization, and the heat loss of the acid solution is low. Especially in cold winter, the acid solution heated by the heating wire 572 has a higher temperature, can react quickly with the metal impurities in the quartz sand, and is conducive to improving the impurity removal efficiency.

[0031] In one embodiment, see Figure 1 The adsorption component 3 also includes a second disk 36, which is rotatably connected to the cavity wall of the reaction chamber 12. The second disk 36 is located between the first disk 31 and the stirring member 21, and is used to receive the quartz sand poured by the first disk 31. The second disk 36 can pour the quartz sand after secondary impurity removal when rotating. In this embodiment, the second disk 36 has the same structure as the first disk 31, and both can be used to adsorb metal impurities in the quartz sand. The difference is that the second disk 36 does not need to use the shaking component 4 to shake the quartz sand flat, because the first disk 31 has already laid the quartz sand flat through the shaking component 4, and the first disk 31 pours the quartz sand in a flat state into the second disk 36 by flipping. The second disk 36 receives the quartz sand poured by the first disk 31 and is naturally in a flat state, so the second disk 36 does not need to shake the quartz sand flat through the shaking component 4. After the second magnetic disk 36 removes impurities from the quartz sand for the second time, the quartz sand is poured into the stirring member 21 by flipping, and the stirring of the stirring member 21 and the pickling solution can quickly remove impurities from the quartz sand. In this embodiment, the second magnetic disk 36 is provided to further improve the impurity removal efficiency of the quartz sand, so that the purity of the quartz sand after pickling is higher. In other embodiments, magnetic disks can be further provided below the second magnetic disk 36, and the number of magnetic disks is not limited, and can be provided specifically according to the effect of the impurity removal required for the quartz sand.

[0032] The first motor 14 and the second motor 15 are arranged outside the reactor 1. The first motor 14 is connected to the outer frame 32 and is used to drive the outer frame 32 and the first magnetic disk 31 to flip back and forth, so as to pour the quartz sand onto the second magnetic disk 36. The second motor 15 is connected to the second magnetic disk 36 and is used to drive the second magnetic disk 36 to flip back and forth, so as to pour the quartz sand onto the stirring member 21. The first magnetic disk 31 and the second magnetic disk 36 both flip back and forth in a cycle, and do not rotate continuously in one direction.

[0033] An arc-shaped through hole (not shown in the figure) is opened on the side wall of the reactor 1, and the driving rod 35 passes through the arc-shaped through hole. When the first motor 14 drives the outer frame 32 to flip back and forth, the outer frame 32 drives the driving rod 35 to make an arc-shaped motion. The path of the arc-shaped through hole is consistent with the path of the driving rod 35, so that the driving rod 35 can move along the arc-shaped through hole when the outer frame 32 flips. The arc-shaped through hole is used to provide a movement space for the driving rod 35.

[0034] The bottom of the reaction chamber 12 is inclined, and the discharge port 13 is located at the lowest point, so that the quartz sand and acid solution in the reaction chamber 12 can flow to the discharge port 13 by their own gravity for easy discharge.

[0035] The acid treatment device also includes a diverter assembly 6, which includes a first pipe 61, a second pipe 62, a main valve 63, a filter valve 64 and a diverter valve 65. One end of the first pipe 61 is connected to the discharge port 13, and the other end is located directly above the hopper 55. The second pipe 62 is integrally formed with the first pipe 61 and is connected to the side of the first pipe 61. The diverter valve 65 is arranged at the connection between the first pipe 61 and the second pipe 62, and is used to control the discharge of the fluid from the outlet of the first pipe 61 or the second pipe 62. The main valve 63 and the filter valve 64 are both located between the discharge port 13 and the second pipe 62, and the main valve 63 is closer to the discharge port 13. When the reaction chamber 12 is acid-washing the quartz sand, the main valve 63 is in a closed state to prevent the acid solution and quartz sand from being discharged in advance. When the quartz sand is pickled, the main valve 63 can be opened and the filter valve 64 can be closed. The filter valve 64 has a filter screen. The mixture of quartz sand and acid solution passes through the main valve 63 and falls to the filter valve 64. The quartz sand is restricted from falling, and the acid solution continues to flow downward through the filter screen of the filter valve 64. At this time, the diverter valve 65 can be adjusted to a state of closing the second pipeline 62, and the acid solution directly falls to the hopper 55 through the first pipeline 61. When the quartz sand needs to be discharged, the diverter valve 65 is first adjusted to a position of closing the first pipeline 61 and opening the second pipeline 62, and then the filter valve 64 is opened, and the quartz sand is discharged through the second pipeline 62 for use in the next process.

[0036] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
