DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 The present invention is described in further detail.

[0038] Embodiment 1

[0039] Reference Figure 1 and Figure 6The present invention discloses a quartz sand impurity removal device for producing glass, comprising a pickling box 1, wherein a pickling inner tank 101 is provided in the pickling box 1, a stirrer 102 is installed in the inner tank, a heater 103 is spirally wound inside the inner tank, the pickling inner tank 101 is used to contain the quartz sand after impurities are removed, and the pickling efficiency and pickling effect of the quartz sand are greatly improved by injecting pickling liquid into the pickling inner tank 101 and by the stirring effect of the stirrer 102 and the heating effect of the heater 103, wherein the stirrer 102 and the heater 103 are integrated on the pickling inner tank 101 through a power supply, so as to be convenient for taking and placing.

[0040] It also includes a pre-treatment shell 2 fixed at the upper opening of the pickling box 1, and a first buffer mechanism 3 and a second buffer mechanism 4 located in the pre-treatment shell 2 for controlling the falling speed of the quartz sand, a magnetic separation mechanism 5 for removing iron from the quartz sand; a negative pressure mechanism 6 for vacuuming and smoking; and a grinding mechanism 7 for removing surface attachments from the quartz sand. The quartz sand is driven by the first buffer mechanism 3 to drive the magnetic separation mechanism 5 and the negative pressure mechanism 6 to operate, and then falls on the grinding mechanism 7 after passing through the second buffer mechanism 4, and enters the pickling box 1 after being ground.

[0041] Before the quartz sand is injected into the pickling box 1, in order to remove impurities from the quartz sand during the feeding process, the falling speed of the quartz sand is reduced to ensure the impurity removal effect of the quartz sand, that is, impurities such as iron, dust, and surface attachments can be removed to a large extent, thereby ensuring the quality of the finished quartz sand during the pickling process.

[0042] Specifically, the first buffer mechanism 3 includes a rotating shaft 301 that is laterally inserted into the upper part of the pre-processing shell 2, and a driving guide plate 302 is connected to the middle part of the rotating shaft 301. The rotating shaft 301 extends out of the pre-processing shell 2 and has driving bevel gears 303 at both ends. The driving guide plate 302 is evenly arranged around the rotating shaft 301 by a plurality of flip plates. The quartz sand is fed onto the driving guide plate 302. The driving guide plate 302 can reduce the feeding speed of the quartz sand, and the gravity of the quartz sand will drive the driving guide plate 302 and the rotating shaft 301 to rotate, thereby causing the driving bevel gears 303 located at both ends of the rotating shaft 301 to rotate.

[0043] The magnetic separation mechanism 5 includes a collection shell 501 and a magnetic cylinder 502 embedded in the side wall of the pre-processing shell 2, and the magnetic cylinder 502 is located inside the collection shell 501. Figure 2As shown, two embedding grooves are opened on the side wall of the pre-processing shell 2, and the collection shell 501 is fixed in the embedding groove with the open end facing the inside of the pre-processing shell 2, and the magnetic cylinder 502 is fixed in the other embedding groove. An adsorption drum 503 is arranged between the collection shell 501 and the magnetic cylinder 502, and a first rotating shaft 504 penetrating the collection shell 501 is arranged on the top of the adsorption drum 503. A driven bevel gear 505 meshing with the driving bevel gear 303 is arranged at one end of the first rotating shaft 504. It can be seen from the gravity of the quartz sand that drives the driving bevel gear 303 to rotate, that the driven bevel gear 505 will drive the adsorption drum 503 connected to the first rotating shaft 504 to rotate, as shown in FIG. Figure 3 As shown, the adsorption drum 503 and the magnetic drum 502 are coaxially arranged, and the adsorption surface 506 of the magnetic drum 502 is semicircular along the inner wall of the adsorption drum 503, which can adsorb more iron filings. A drop opening 507 is opened at the bottom of the collection shell 501, and the drop opening 507 is located on the side of the magnetic drum 502 away from the adsorption surface 506. Since the adsorption surface 506 is always facing the inside of the pre-treatment shell 2, the ferromagnetic impurities in the quartz sand will be continuously moved toward the adsorption surface 506 under the action of the magnetic force and adsorbed on the drum 503. The drum 503 is driven to rotate by the first rotating shaft 504, while the adsorption surface 506 remains fixed. After the drum 503 passes by the adsorption surface 506, the ferromagnetic impurities adsorbed on the surface of the drum 503 lose their magnetic effect and fall off from the drum 503 under the action of gravity, and are discharged through the drop port 507 set under the collection shell 501. The ferromagnetic impurities are cleaned more thoroughly, so there is no need to manually clean the magnetic separation mechanism 5 regularly, which reduces the burden on the operating workers and also realizes continuous impurity removal.

[0044] In addition, if Figure 2 As shown, the negative pressure mechanism 6 includes a negative pressure shell 601 embedded in the side wall of the pre-treatment shell 2, and the bottom of the adsorption drum 503 is provided with a second rotating shaft 602 that penetrates the collection shell 501. The second rotating shaft 602 is located in the negative pressure shell 601. One end of the impeller 603 is sleeved on the outside. That is, when the drum 503 rotates, it will drive the second rotating shaft 602 at the bottom to rotate, and the second rotating shaft 602 will drive the impeller 603 to rotate. The impeller 603 is located in the negative pressure shell 601. Under the action of the impeller 603, the impeller 603 located in the pre-treatment shell 2 will be affected by the negative pressure and collected by the negative pressure shell 601. The negative pressure shell 601 is located at one end of the pre-treatment shell 2 and is provided with a filter 604. The filter 604 can prevent the quartz sand from entering the negative pressure shell 601, thereby ensuring the normal operation of the impeller 603 in the negative pressure shell 601. As a preferred solution of this implementation, the negative pressure shell 601 is connected to the drop port 507 at the bottom of the collection shell 501, that is, the ferromagnetic impurities collected by the magnetic separation mechanism 5 and the dust collected by the negative pressure mechanism 6 are collected uniformly.

[0045] like Figure 1 As shown, by setting the grinding mechanism 7, not only can the surface attachments of the quartz sand be removed, but also the quartz sand passing through the grinding mechanism 7 can be ensured to be more rounded, and the subsequent processes can be reduced, so as to meet the requirements of the required quartz sand. Specifically, the grinding mechanism 7 includes an annular guide table 701 fixed at the lower part of the pre-treatment shell 2, and a grinding roller group 702 is provided on the inner side of the annular guide table 701. The grinding roller group 702 is installed on the pre-treatment shell 2. The annular guide table 701 is used to introduce the quartz sand into the grinding roller group 702, and the quartz sand is surface treated by the grinding roller group 702. Among them, a smoke exhaust channel 703 connecting the pickling box 1 and the negative pressure shell 601 is opened in the annular guide table 701. The temperature is increased by the heater 103 to carry out pickling. Although the pickling efficiency is increased, the temperature-increasing pickling will generate a large amount of smoke. In order to avoid environmental pollution caused by the smoke, the smoke exhaust channel 703 is opened, and the negative pressure mechanism 6 arranged above is cooperated to discharge the smoke and the smoke mixed with dust.

[0046] In addition, if Figure 1 and Figure 4 A second buffer mechanism 4 is also provided, because after the quartz sand passes through the first buffer mechanism 3 and reaches the grinding mechanism 7, it falls freely. In order to prevent the quartz sand from impacting the grinding mechanism 7, the second buffer mechanism 4 is used to reduce the falling speed of the quartz sand entering the grinding mechanism 7 for a second time. Specifically, the second buffer mechanism 4 includes an arched platform 401 fixed on the inner wall of the pre-processing shell 2, and the top of the arched platform 401 is connected to a buffer plate 403 through a spring 402. A rubber buffer layer can be provided on the surface of the buffer plate 403. After the quartz sand falls on the buffer plate 403, it flows along the arched platform 401 to the annular guide platform 701 under the action of the spring 402, and is guided to the grinding roller group 702.

[0047] Working principle: the quartz sand to be pickled is introduced through the upper part of the pre-treatment shell 2. The quartz sand first passes through the first buffer mechanism 3. After being buffered by the driving guide plate 302 of the first buffer mechanism 3, the driving guide plate 302 drives the magnetic separation mechanism 5 and the negative pressure mechanism 6 to operate, and the quartz sand passing through the first buffer mechanism 3 is subjected to iron removal, dust removal and fume removal treatment. Then, after being buffered by the second buffer mechanism 4, it falls on the grinding mechanism 7, which can not only remove the surface attachments of the quartz sand, but also ensure that the quartz sand passing through the grinding mechanism 7 is more rounded, and enters the pickling box 1 after grinding.

[0048] Embodiment 2

[0049] Reference Figure 4-Figure 5In order to achieve the effect of grinding the quartz sand and removing the surface attachments during the grinding of the quartz sand in this embodiment, based on the same concept as the above-mentioned embodiment 1, the quartz sand impurity removal device for producing glass further includes a water washing mechanism 8 at the bottom of the arched platform 401. Through the washing of the water washing mechanism 8, the surface attachments of the quartz sand after passing through the grinding mechanism 7 are basically separated from the quartz sand, and after washing, up to 80% of the surface attachments can be removed.

[0050] Specifically, the water washing mechanism 8 includes a transmission box 801 fixed in the recessed part of the arch platform 401, a double-sided rack 802 penetrating the arch platform 401 is fixed at the bottom of the buffer plate 403, two groups of gears 803 are arranged inside the transmission box 801, the two groups of gears 803 are symmetrically meshed on both sides of the double-sided rack 802, the central axis of the gear 803 passes through the two ends of the transmission box 801, and a swing frame 804 is connected between them, and a water washing nozzle 805 is connected to the swing frame 804.

[0051] The water washing is mainly performed by spraying the liquid for washing the quartz sand onto the surface of the quartz sand through the water washing nozzle 805. When the buffer plate 403 is buffered by the quartz sand, it drives the double-sided rack 802 to move up and down. The movement of the double-sided rack 802 drives the two sets of gears 803 to swing symmetrically, which drives the water washing nozzle 805 to spray and wash the quartz sand on the grinding mechanism 7 evenly.

[0052] Embodiment 3

[0053] Reference Figure 6 In order to achieve the quartz sand pickling effect and the recycling of the pickling liquid in this embodiment, based on the same concept as the above-mentioned embodiment 2, the quartz sand impurity removal device for producing glass also includes a water washing nozzle 805 connected to the pickling tank 1 through a circulating water pump 9, wherein, in order to prevent the impurities in the pickling tank 1 from entering the water washing nozzle through the circulating water pump 9, a filter is arranged at its entry end. The pickling liquid in the pickling tank 1 is sprayed toward the quartz sand on the grinding mechanism 7 through the water washing nozzle 805 through the circulating water pump 9, which accelerates the dissolution of impurities in the quartz sand, makes the acid showering more uniform, and saves costs.

[0054] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
