One ends of the four first sliders away from the first chutes are fixedly connected to the side wall of the guiding sleeve.

[0019] The steps of a method for pickling quartz sand include:

[0020] Step 1: First, the staff opens the sliding door arranged on the installation shell. At this time, the pickling acid solution placement box is placed into the inner cavity of the installation shell, and then the sliding door is closed again. At the same time, the staff pours quartz sand into the inner cavity of the heating box from the feed inlet arranged above the installation shell.

[0021] Step 2: The staff can drive the heating box to rotate through the driving assembly. When the heating box rotates, it can drive the circular installation plate to rotate through the conical connecting rod. When the circular installation plate rotates, it can drive the rotating shaft to rotate. Since a guiding chute is opened on the rotating shaft, and a guiding slider is slidably arranged in the inner cavity of the guiding chute, and a limiting rod is connected to the outer wall of the guiding slider and is connected to the guiding sleeve, and a first sliding mechanism is arranged on the outer side wall of the guiding sleeve, the guiding sleeve can move vertically downward.

[0022] Step 3: When the guiding sleeve moves vertically downward, it will be able to drive the moving rod to move vertically downward. Through the moving rod, it will be able to drive the circular moving plate to move vertically downward. When the circular moving plate moves vertically downward, it will be able to drive the mounting rod to move vertically downward, thereby driving the conical plate to move downward;

[0023] Step 4: When the circular moving plate moves to a certain position, it will be able to squeeze the ring insertion plate to move vertically downward with the assistance of the slide rail. At this time, the conical plate continues to move downward; until the ring insertion plate moves to a certain position, at this time, the second rectangular notch opened on the ring insertion plate and the first rectangular notch opened on the ring insertion plate are in a semi-closed state. Therefore, the quartz sand accumulated on the ring placement plate outside the outer wall of the ring socket cylinder can slowly enter the inner ring of the ring socket cylinder and is located above the conical plate. Until the second rectangular notch and the first rectangular notch are aligned, it will be completely opened. Therefore, the quartz sand can be quickly introduced above the conical plate. At this time, when the guiding sleeve moves upward, it will be able to drive the circular moving plate to move upward, so that the conical plate at this time drives the quartz sand above to move upward. At the same time, the circular moving plate will lose the extrusion force on the ring insertion plate, so that the ring insertion plate can be reset with the assistance of the second return spring. When the ring insertion plate is reset, at this time, the circular moving plate will continue to pull the conical plate upward until the second rectangular notch at the conical plate and the ring insertion plate is at the same horizontal plane. At this time, the quartz sand placed above the conical plate can return from the inclined surface and the second rectangular notch above the ring placement plate, thereby realizing the transposition of the quartz sand and making its preheating effect by the heating box better;

[0024] Step 5: At the same time, when the driving component rotates, it can squeeze the material guiding plate to move vertically downward with the assistance of the second sliding mechanism. When the material guiding plate moves vertically downward, it will be able to drive the sealing rod to move vertically downward, so that the sealing rod can leave the material guiding plate. Therefore, the quartz sand can be discharged and enter the pickling acid solution placement box arranged below for pickling and cooling.

[0025] The present invention has the following beneficial effects compared with the prior art:

[0026] In the present invention, the driving component is used to make the material guiding plate move vertically downward. When the material guiding plate moves vertically downward, it can make the sealing rod move vertically downward, so that the quartz sand is discharged and enters the pickling acid solution placement box arranged below for pickling and cooling. At the same time, the driving component can also drive the heating box to rotate, so that the internal structure of the limit rotation unit moves vertically downward, so that the material changing unit can change the material of the placed quartz sand.

Four first rectangular notches 5021 and second rectangular notches 5031 arranged in a circular distribution are respectively provided on the circular ring socket cylinder 502 and the circular ring insertion plate 503. Each first rectangular notch 5021 and second rectangular notch 5031 are aligned with each other and fit together. The blanking unit 400 includes a material guiding plate 401. The material guiding plate 401 is provided at the bottom of the circular ring mounting plate 3016. Four sealing rods 4014 arranged in a circular distribution are fixedly installed above the material guiding plate 401. The four sealing rods 4014 respectively penetrate through the circular ring mounting plate 3016 in a sealed manner. The transmission unit 200 includes a driving component. The driving component is used to drive the heating box 301 to rotate, and the driving component is also used to push the material guiding plate 401 to move vertically downward. By the driving component, the material guiding plate 401 moves vertically downward. When the material guiding plate 401 moves vertically downward, the sealing rods 4014 can move vertically downward, so that the quartz sand can be discharged and enter the pickling acid solution placement tank provided below for pickling and cooling. At the same time, the driving component can also drive the heating box 301 to rotate, so that the internal structure of the limit rotation unit 300 moves vertically downward, so that the material changing unit 500 can change the material of the placed quartz sand.

[0047] As Figures 2 to 4As shown, in the specific implementation manner, the driving assembly includes a servo motor 201. The servo motor 201 is disposed above the mounting housing 101.

When the rotating rod 2011 rotates, the driving gear 2012 can be driven to rotate. When the driving gear 2012 rotates, the toothed ring 2013 can be driven to rotate. When the toothed ring 2013 rotates, the heating box 301 can be driven to rotate.

[0048] As Figures 2 to 4 shown, further, the driving assembly further includes a worm 202. A worm gear 2021 is meshingly installed on the worm 202.

In this setting, it is ensured that when the driving gear 2012 rotates, the worm 202 disposed at the bottom can be driven to rotate. When the worm 202 rotates, the worm gear 2021 can be driven to rotate. Since the worm 202 and the worm gear 2021 have a speed reduction effect and the reduction ratio is 1:20, when the worm gear 2021 rotates, the rotating rod 2022 can be driven to rotate. When the rotating rod 2022 rotates, the cam 2023 can be driven to rotate, so that after the cam 2023 rotates a certain angle, it can squeeze the material guiding plate 401 to move vertically downward with the assistance of the second sliding mechanism.

[0049] As Figures 2 to 6 shown, further, a circular mounting plate 3012 is disposed in the inner cavity of the heating box 301. Conical connecting rods 3011 are fixedly installed at the four - week ends of the circular mounting plate 3012 respectively. The four conical connecting rods 3011 are circumferentially distributed. One end of each of the four conical connecting rods 3011 away from the circular mounting plate 3012 is fixedly connected to the inner wall of the heating box 301. In this setting, it is ensured that when the heating box 301 rotates, the circular mounting plate 3012 can be driven to rotate through the conical connecting rods 3011.

At the same time, the connecting rods 3015 penetrate through the circular ring placing plate 501 movably, and the bottom ends are fixedly connected with the circular ring mounting plate 3016. Among them, the circular ring mounting plate 3016 is connected to the outer wall of the mounting shell 101 through the positioning plate 3017. Therefore, it can be ensured that the protection cylinder 3013 will not rotate.

[0051] As Figures 4 to 7 shown, further, a rotating shaft 302 is fixedly installed in the middle of the bottom of the circular mounting plate 3012. A guiding sliding groove 3021 is arranged on the rotating shaft 302. A guiding sliding block 3022 is slidably installed on the guiding sliding groove 3021.

One end of the limiting rod 3023 far away from the guiding sliding block 3022 is fixedly connected with a guiding sleeve 3024. The guiding sleeve 3024 is sleeved on the rotating shaft 302. In this setting, when the circular mounting plate 3012 rotates, it will be able to drive the rotating shaft 302 to rotate. Because the guiding sliding groove 3021 is arranged on the rotating shaft 302, and the guiding sliding block 3022 is slidably arranged in the inner cavity of the guiding sliding groove 3021. And the outer wall of the guiding sliding block 3022 is connected with the limiting rod 3023, and the limiting rod 3023 is connected with the guiding sleeve 3024. At the same time, a first sliding mechanism is arranged on the outer side wall of the guiding sleeve 3024. Therefore, it can make the guiding sleeve 3024 move vertically downward.

One ends of the four first sliding blocks 3026 away from the first sliding grooves 3025 are fixedly connected to the side wall of the guiding sleeve 3024. Two symmetrically arranged moving rods 3027 are fixedly installed at the bottom of the guiding sleeve 3024. The two moving rods 3027 respectively pass through the protective cylinder 3013 movably. One ends of the two moving rods 3027 away from the guiding sleeve 3024 are connected with a circular moving plate 3028. An installation rod 5041 is fixedly installed at the bottom of the circular moving plate 3028. The other end of the installation rod 5041 is fixedly connected with a conical plate 504. The conical plate 504 is arranged in the inner ring of the ring socket cylinder 502. In this setting, the first sliding grooves 3025 in the first sliding mechanism are opened in the inner cavity of the protective cylinder 3013, and the first sliding blocks 3026 slidably installed in the inner cavities of the first sliding grooves 3025 are fixedly connected to the guiding sleeve 3024.

The ring installation plate 3016 is connected to the outer wall of the installation shell 101 through a positioning plate 3017. Therefore, it can be ensured that the protective cylinder 3013 will not rotate, and at the same time, the guiding sleeve 3024 can also move vertically downward.

[0053] Embodiment 2:

[0054] Different from the above-mentioned embodiment and this embodiment is that: As Figure 2 shown, in a quartz sand pickling device, a second sliding mechanism is arranged at the side wall of the material guiding plate 401. The second sliding mechanism includes two second sliding grooves 4012, and the two second sliding grooves 4012 are respectively opened on the inner wall of the installation shell 101. The two second sliding grooves 4012 are symmetric to each other. A sliding rod 4011 is slidably installed in each of the inner cavities of the two second sliding grooves 4012. The two sliding rods 4011 are symmetric to each other. One ends of the two sliding rods 4011 opposite to each other are fixedly connected to the material guiding plate 401. A first return spring 4013 is arranged at the bottom of the inner cavities of the two second sliding grooves 4012. The other end of the first return spring 4013 is fixedly connected to the sliding rod 4011. In this setting, it is ensured that when the cam 2023 leaves the material guiding plate 401, at this time, the material guiding plate 401 can be reset with the assistance of the first return spring 4013.

[0055] As Figures 5 to 6 and Figures 8 to 9As shown in the figure, in the specific implementation manner, four sliding rails 5022 are provided on both opposite side walls of the inner cavity of the circular ring socket cylinder 502. The four sliding rails 5022 are symmetric with each other in pairs. On one side wall where the four sliding rails 5022 are opposite to each other in pairs, a circular ring plug-in board 503 is fixedly connected. At the bottom of the circular ring plug-in board 503, four second return springs 5023 arranged in a circumferential distribution are fixedly installed. The other ends of the four second return springs 5023 are fixedly connected to the bottom of the inner cavity of the circular ring socket cylinder 502. In this setting, when the guiding sleeve 3024 moves upward, it can drive the circular moving plate 3028 to move upward. At this time, the conical plate 504 drives the quartz sand above to move upward. At the same time, the circular moving plate 3028 will lose the extrusion force on the circular ring plug-in board 503, so that the circular ring plug-in board 503 can be reset with the assistance of the second return spring 5023. When the circular ring plug-in board 503 is reset, at this time, the circular moving plate 3028 will continue to pull the conical plate 504 upward until the second rectangular notch 5031 at the conical plate 504 and the circular ring plug-in board 503 is at the same horizontal plane. At this time, the quartz sand placed above the conical plate 504 can return from the inclined surface and the second rectangular notch 5031 to above the circular ring placement plate 501, thus realizing the transposition of the quartz sand.

[0056] Embodiment 3:

At the same time, the staff pours quartz sand into the inner cavity of the heating box 301 from the feed port 1013 provided above the installation housing 101.

[0059] Step 2: The staff can drive the heating box 301 to rotate through the driving component. When the heating box 301 rotates, it can drive the circular mounting plate 3012 to rotate through the conical connecting rod 3011. When the circular mounting plate 3012 rotates, it can drive the rotating shaft 302 to rotate. Since the guiding chute 3021 is provided on the rotating shaft 302, and the guiding slider 3022 is slidably arranged in the inner cavity of the guiding chute 3021, and the outer wall of the guiding slider 3022 is connected with the limiting rod 3023, and the limiting rod 3023 is connected to the guiding sleeve 3024, and at the same time, a first sliding mechanism is arranged on the outer side wall of the guiding sleeve 3024, so that the guiding sleeve 3024 can move vertically downward.

[0060] Step 3: When the guiding sleeve 3024 moves vertically downward, it will be able to drive the moving rod 3027 to move vertically downward. Through the moving rod 3027, it will be able to drive the circular moving plate 3028 to move vertically downward. When the circular moving plate 3028 moves vertically downward, it will be able to drive the mounting rod 5041 to move vertically downward, thereby driving the conical plate 504 to move downward;

[0061] Step 4: When the circular moving plate 3028 moves to a certain position, it will be able to squeeze the ring plug-in plate 503 to move vertically downward with the assistance of the slide rail 5022. At this time, the conical plate 504 continues to move downward; until the ring plug-in plate 503 moves to a certain position, the second rectangular notch 5031 opened on the ring plug-in plate 503 and the first rectangular notch 5021 opened on the ring plug-in plate 503 are in a semi-closed state. Therefore, the quartz sand accumulated on the ring placement plate 501 outside the outer wall of the ring socket cylinder 502 can slowly enter the inner ring of the ring socket cylinder 502 and be located above the conical plate 504. Until the second rectangular notch 5031 and the first rectangular notch 5021 are aligned, it will be completely opened. Therefore, the quartz sand can be quickly introduced above the conical plate 504. At this time, when the guiding sleeve 3024 moves upward, it will be able to drive the circular moving plate 3028 to move upward, so that the conical plate 504 at this time drives the quartz sand above to move upward. At the same time, the circular moving plate 3028 will lose the extrusion force on the ring plug-in plate 503, so that the ring plug-in plate 503 can be reset with the assistance of the second return spring 5023. When the ring plug-in plate 503 is reset, at this time the circular moving plate 3028 will continue to pull the conical plate 504 upward until the conical plate 504 and the second rectangular notch 5031 at the ring plug-in plate 503 are at the same horizontal plane. At this time, the quartz sand placed above the conical plate 504 can return from the inclined surface and the second rectangular notch 5031 to above the ring placement plate 501, thereby realizing the transposition of the quartz sand and making its preheating effect by the heating box 301 better;

[0062] Step 5: At the same time, when the driving component rotates, it can squeeze the material guiding plate 401 to move vertically downward with the assistance of the second sliding mechanism. When the material guiding plate 401 moves vertically downward, it will be able to drive the sealing rod 4014 to move vertically downward, so that the sealing rod 4014 can leave the material guiding plate 401. Therefore, the quartz sand can be discharged and enter the pickling acid solution placement tank 102 arranged below for pickling and cooling.

[0063] The implementation principle of a quartz sand pickling device and its method in this embodiment is as follows:

[0064] Step 1: First, the staff opens the sliding door 1011 provided on the installation housing 101. At this time, the pickling solution placement box 102 is placed into the inner cavity of the installation housing 101, and then the sliding door 1011 is closed again. Meanwhile, the staff pours quartz sand into the inner cavity of the heating box 301 from the feed port 1013 provided above the installation housing 101;

[0065] Step 2: The staff then starts the servo motor 201. The servo motor 201 can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the driving gear 2012 to rotate. When the driving gear 2012 rotates, it can drive the toothed ring 2013 to rotate. When the toothed ring 2013 rotates, it can drive the heating box 301 to rotate. When the heating box 301 rotates, it can drive the circular mounting plate 3012 to rotate through the conical connecting rod 3011. When the circular mounting plate 3012 rotates, it can drive the rotating shaft 302 to rotate. Since the guiding chute 3021 is provided on the rotating shaft 302, and the guiding slider 3022 is slidably arranged in the inner cavity of the guiding chute 3021, and the outer wall of the guiding slider 3022 is connected with the limiting rod 3023, and the limiting rod 3023 is connected with the guiding sleeve 3024. At the same time, a first sliding mechanism is provided on the outer side wall of the guiding sleeve 3024. Therefore, the guiding sleeve 3024 can move vertically downward. In the first sliding mechanism, the first chute 3025 is provided in the inner cavity of the protective cylinder 3013, and the first slider 3026 slidably installed in the inner cavity of the first chute 3025 is fixedly connected with the guiding sleeve 3024. Since the fixed rod 3014 is fixedly connected to the outer side wall of the protective cylinder 3013, and the fixed rod 3014 is fixedly connected to the bottom of the connecting rod 3015. At the same time, the connecting rod 3015 movably penetrates through the circular ring placement plate 501 and is fixedly connected to the circular ring mounting plate 3016 at the bottom end. The circular ring mounting plate 3016 is connected to the outer wall of the installation housing 101 through the positioning plate 3017. Therefore, it can be ensured that the protective cylinder 3013 will not rotate;

[0066] Step 3: When the guiding sleeve 3024 moves vertically downward, it can drive the moving rod 3027 to move vertically downward. Through the moving rod 3027, it can drive the circular moving plate 3028 to move vertically downward. When the circular moving plate 3028 moves vertically downward, it can drive the mounting rod 5041 to move vertically downward, thereby driving the conical plate 504 to move downward;

[0067] Step Four: When the circular moving plate 3028 moves to a certain position, it will be able to squeeze the ring plug-in plate 503 to move vertically downward with the assistance of the slide rail 5022, and at this time, the conical plate 504 continues to move downward; until the ring plug-in plate 503 moves to a certain position, at this time, the second rectangular notch 5031 opened on the ring plug-in plate 503 and the first rectangular notch 5021 opened on the ring plug-in plate 503 are in a semi-closed state. Therefore, the quartz sand accumulated on the ring placement plate 501 outside the ring socket cylinder 502 can slowly enter the inner ring of the ring socket cylinder 502 and be located above the conical plate 504. Until the second rectangular notch 5031 and the first rectangular notch 5021 are aligned, it will be completely opened. Therefore, the quartz sand can be quickly introduced above the conical plate 504. At this time, the guide sleeve 3024 moves upward and will be able to drive the circular moving plate 3028 to move upward, so that the conical plate 504 drives the quartz sand above to move upward. At the same time, the circular moving plate 3028 will lose the extrusion force on the ring plug-in plate 503, so that the ring plug-in plate 503 can be reset with the assistance of the second return spring 5023. When the ring plug-in plate 503 is reset, at this time, the circular moving plate 3028 will continue to pull the conical plate 504 upward until the conical plate 504 and the second rectangular notch 5031 at the ring plug-in plate 503 are at the same horizontal plane. At this time, the quartz sand placed above the conical plate 504 can return from the inclined surface and the second rectangular notch 5031 above the ring placement plate 501, thus realizing the transposition of the quartz sand and making its preheating effect by the heating box 301 better;

[0068] Step Five: When the driving gear 2012 rotates, it will be able to drive the worm 202 arranged at the bottom to rotate. When the worm 202 rotates, it will be able to drive the worm wheel 2021 to rotate. Because the worm 202 and the worm wheel 2021 have a speed reduction effect and the reduction ratio is 1:20, when the worm wheel 2021 rotates, it can make the rotating rod 2022 rotate. When the rotating rod 2022 rotates, it will be able to drive the cam 2023 to rotate, so that the cam 2023 can squeeze the material guiding plate 401 to move vertically downward with the assistance of the second sliding mechanism after rotating a certain angle. When the material guiding plate 401 moves vertically downward, it will be able to drive the sealing rod 4014 to move vertically downward, so that the sealing rod 4014 can leave the material guiding plate 401. Therefore, the quartz sand can be discharged and enter the pickling acid solution placement box 102 arranged below for pickling and cooling.
