[0025] In order to promote the efficient and high-quality manufacturing of photovoltaic cells, it is necessary to fill the inside of the photovoltaic quartz tube with high-purity quartz sand to provide silicon source, control the melting process, maintain temperature stability and prevent impurity contamination. Since the quartz tube is a slender tubular body, if the quartz sand cannot be evenly filled inside the photovoltaic quartz tube, it is easy to cause uneven temperature distribution inside the quartz tube, thereby affecting the crystallization quality of the silicon wafer and the performance of the photovoltaic cell.
[0026] See also Figure 1-Figure 5 As shown, the device includes a photovoltaic quartz tube body 1, which is made of transparent material as a whole. Both ends of the photovoltaic quartz tube body 1 are movably connected with end plugs 11 for sealing the inside thereof. The upper end of the inner wall of the photovoltaic quartz tube body 1 is movably connected with a sand filling component 2 for uniformly filling sand inside the photovoltaic quartz tube body 1. A sand discharging component 3 for controlling the discharging of high-purity quartz sand is installed in the middle of the sand filling component 2.
[0027] First, the specific structure of the sand loading component 2 is disclosed. The sand loading component 2 includes two cardboards 22 installed on the upper end of the inner wall of the photovoltaic quartz tube body 1, and a sand loading arc plate 21 is movably installed between the two cardboards 22. A sand entry bin 24 is provided inside the sand loading arc plate 21, and a sand entry cover 23 is sealed and installed at the opening of the sand entry bin 24. A plurality of discharge pipes 25 are fixedly connected to the bottom of the sand loading arc plate 21. By setting the two cardboards 22 on the upper end of the inner wall of the photovoltaic quartz tube body 1, the sand loading arc plate 21 can be movably installed between the two cardboards 22. By opening the sand entry cover 23, high-purity quartz sand can be poured into the inside of the sand entry bin 24. By evenly connecting the plurality of discharge pipes 25 at the bottom end of the sand loading arc plate 21, the high-purity quartz sand can be evenly laid inside the photovoltaic quartz tube body 1. After the sand loading is completed, the sand loading arc plate 21 is slid out of the interior of the photovoltaic quartz tube body 1, and the end plug 11 is inserted, so that the photovoltaic quartz tube body 1 can be used normally.
[0028] Secondly, the specific structure of the sand lowering assembly 3 is disclosed. The sand lowering assembly 3 includes an inner groove 31 opened at the bottom of the sand inlet bin 24. The inner groove 31 is provided with a first bonding plate 33 and a second bonding plate 34 for sliding. The ends of the first bonding plate 33 and the second bonding plate 34 are magnetically bonded. The first bonding plate 33 and the second bonding plate 34 are fixedly connected to a sand lowering rod 32 on one side near the opening of the inner groove 31. When the high-purity quartz sand inside the sand-filling arc plate 21 needs to be filled into the interior of the photovoltaic quartz tube body 1, the two sand lowering rods 32 are slid in the opposite direction to drive the first bonding plate 33 and the second bonding plate 34 to separate, so that several discharge ports at the bottom of the sand inlet bin 24 can be opened at the same time, which is convenient for regulating the amount and speed of sand discharge, and improving the feeding effect of high-purity quartz sand.
[0029] The improvement of this embodiment is that: first, the end plugs 11 arranged at both ends of the photovoltaic quartz tube body 1 are used to make the interior of the photovoltaic quartz tube body 1 made of transparent material sealed, and the two card plates 22 arranged at the upper end of the inner wall of the photovoltaic quartz tube body 1 make the sand-filling arc plate 21 movably installed between the two card plates 22, and the sand-inlet cover 23 is opened to pour high-purity quartz sand into the sand-inlet bin 24. Through a number of feed pipes 25 evenly connected to the bottom end of the sand-filling arc plate 21, the high-purity quartz sand can be evenly laid inside the photovoltaic quartz tube body 1. After the sand filling is completed, the sand-filling arc plate 21 is slid out of the interior of the photovoltaic quartz tube body 1, and the end plugs 11 are inserted, so that the photovoltaic quartz tube body 1 can be used normally;
[0030] When the high-purity quartz sand inside the sand-filled arc plate 21 needs to be filled into the interior of the photovoltaic quartz tube body 1, the two sand-discharging rods 32 are slid in the opposite direction to drive the first bonding plate 33 and the second bonding plate 34 to separate, so that several discharge ports at the bottom of the sand inlet bin 24 can be opened at the same time, which is convenient for controlling the amount of sand discharged and the speed of sand discharged, thereby improving the feeding effect of the high-purity quartz sand.
[0031] Considering the fluidity of high-purity quartz sand during loading, in order to reduce the outflow of high-purity quartz sand during loading, Figure 2-Figure 3 As shown, a vertical pole 41 is fixedly installed at the bottom of one end of the sand-filled arc plate 21 , and a support plate 4 is fixedly connected to the bottom of the vertical pole 41 , and the surface of the support plate 4 is in contact with the inner wall of the photovoltaic quartz tube body 1 .
[0032] The improvement lies in that: by utilizing a vertical pole 41 installed at the bottom of one end of the sand-filling arc plate 21 and a support plate 4 installed at the bottom of the vertical pole 41, and the surface of the support plate 4 fits with the inner wall of the photovoltaic quartz tube body 1, the end of the photovoltaic quartz tube body 1 can be sealed, effectively reducing the outflow of high-purity quartz sand during the sand filling process.
[0033] Since the high-purity quartz sand needs to be stored in the sand inlet bin 24 when loading, and the material discharge point of the sand inlet bin 24 is separated by the first bonding plate 33 and the second bonding plate 34, in order to reduce the situation that the high-purity quartz sand flows out from the bonding gap between the first bonding plate 33 and the second bonding plate 34, Figure 1-Figure 2 As shown, an end of the first bonding plate 33 close to the second bonding plate 34 is fixedly connected to an extension plate 51 , and an end of the second bonding plate 34 close to the first bonding plate 33 is provided with a bonding slot 5 that is bonded to the surface of the extension plate 51 .
[0034] The improvement lies in that: by utilizing an extension plate 51 fixedly connected to the end of the first bonding plate 33 and a bonding slot 5 opened at the end of the second bonding plate 34, the first bonding plate 33 and the second bonding plate 34 can be inserted and connected, which effectively reduces the gap between the first bonding plate 33 and the second bonding plate 34 and improves the internal sealing of the sand inlet bin 24.
[0035] In summary, the working principle of this scheme is as follows: first, the end plugs 11 arranged at both ends of the photovoltaic quartz tube body 1 are used to seal the interior of the photovoltaic quartz tube body 1 made of transparent material, and the two card plates 22 arranged at the upper end of the inner wall of the photovoltaic quartz tube body 1 make the sand-filling arc plate 21 movably installed between the two card plates 22, and the sand-entry cover 23 is opened to pour high-purity quartz sand into the interior of the sand-entry bin 24, and the high-purity quartz sand can be evenly laid in the interior of the photovoltaic quartz tube body 1 by a plurality of feed pipes 25 evenly connected to the bottom end of the sand-filling arc plate 21, and the vertical pole 41 installed at the bottom of one end of the sand-filling arc plate 21 and the support plate 4 installed at the bottom of the vertical pole 41 can achieve the effect of blocking the end of the photovoltaic quartz tube body 1, and after the sand filling is completed, the sand-filling arc plate 21 is slid out of the interior of the photovoltaic quartz tube body 1, and the end plug 11 is plugged into the end of the photovoltaic quartz tube body 1, so that the photovoltaic quartz tube body 1 can be used normally;
[0036] When the high-purity quartz sand inside the sand-filled arc plate 21 needs to be filled into the interior of the photovoltaic quartz tube body 1, the two sand lowering rods 32 are slid in the opposite direction to drive the first bonding plate 33 and the second bonding plate 34 to separate, so that several feeding ports at the bottom of the sand entry bin 24 can be opened at the same time, which is convenient for regulating the amount of sand and the speed of sand discharge, thereby improving the feeding effect of high-purity quartz sand. By using the extension plate 51 fixedly connected to the end of the first bonding plate 33 and the bonding slot 5 opened at the end of the second bonding plate 34, the first bonding plate 33 and the second bonding plate 34 can be inserted and connected, which effectively reduces the gap between the first bonding plate 33 and the second bonding plate 34, thereby improving the internal sealing of the sand entry bin 24.
