Description

Technical Field

[0001] This utility model relates to the field of furnace tube cleaning technology, specifically a tool for cleaning quartz fragments inside high-temperature furnace tubes in the photovoltaic industry. Background Technology

[0002] High-temperature furnace tubes are core components in photovoltaic cell manufacturing, mainly used for key processes such as high-temperature deposition, diffusion, and sintering. The quartz tubes inside the high-temperature furnace tubes are subjected to thermal shock and chemical corrosion at temperatures above 1000°C for extended periods, which can cause the quartz tubes to crack. In such cases, the damaged quartz tubes need to be replaced.

[0003] After the quartz tube inside the high-temperature furnace tube breaks, the machine needs to be shut down until the temperature inside the furnace tube cools down to room temperature before the broken quartz tube is pulled out of the furnace tube. After that, workers need to wear protective gloves to clean the quartz tube fragments remaining on the inner wall of the furnace tube. In some cases, workers may even need to enter the furnace tube to clean the quartz tube fragments deep inside. After the quartz tube fragments inside the high-temperature furnace tube are cleaned, a new quartz tube is inserted into the high-temperature furnace tube for fixed installation.

[0004] The existing method of cleaning quartz tube fragments inside high-temperature furnace tubes requires workers to enter the furnace tubes for cleaning. However, the limited space inside the furnace tubes makes the cleaning work difficult. Furthermore, workers are prone to inhaling quartz powder while cleaning inside the furnace tubes, which can affect their health.

[0005] Therefore, a tool for cleaning quartz fragments from high-temperature furnace tubes in the photovoltaic industry is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The tool for cleaning quartz fragments inside a high-temperature furnace tube in the photovoltaic industry includes multiple telescopic rods; the length of the multiple telescopic rods after extension is greater than the inner cavity length of the high-temperature furnace tube; a fixed seat is fixedly connected to one end of the multiple telescopic rods that extends into the high-temperature furnace tube; multiple support rods are fixedly connected around the outer ring of the fixed seat; a suction cup is fixedly connected to one end of the support rod away from the fixed seat.

[0008] Preferably, a cleaning hook is fixed to one end of the support rod away from the fixed base.

[0009] Preferably, a hydraulic breaker is fixed to one end of the other support rod away from the fixed base.

[0010] Preferably, a cone seat is fixedly connected to the center of the side of the breaker away from the fixed seat.

[0011] Preferably, it also includes a fixing ring; the fixing ring can be fixedly connected to the flange of the furnace tube port; a vertical rod is fixedly connected to the middle of the fixing ring; a lifting cylinder is slidably installed on the outer ring of the vertical rod; a support rod is fixedly connected to one side of the lifting cylinder; and an open lifting ring is rotatably installed at the bottom end of the support rod.

[0012] Preferably, a positioning cylinder is rotatably mounted at the bottom of the lifting cylinder; the positioning cylinder is slidably mounted on the outer ring of the upright.

[0013] Preferably, the outer and inner walls of each section of the multi-section telescopic rod are threaded.

[0014] The advantages of this utility model are: 1. This utility model discloses a tool for cleaning quartz fragments inside high-temperature furnace tubes in the photovoltaic industry. It comprises a multi-section telescopic rod, a fixed base, a support rod, and a suction cup. The multi-section telescopic rod extends into the furnace tube, causing the fixed base to move to the quartz fragments remaining on the inner wall of the furnace tube. The suction cup is then directed towards the quartz fragments. By swinging the multi-section telescopic rod, the fixed base swings, causing the suction cup to press against and adhere to the quartz fragments. The multi-section telescopic rod is then pulled out of the furnace tube, and the fixed base and suction cup are removed. Workers can then remove the quartz fragments adsorbed on the suction cup. This avoids requiring workers to enter the furnace tube for cleaning, facilitating the cleaning process and ensuring the health of the workers.

[0015] 2. The tool described in this utility model for cleaning quartz fragments inside high-temperature furnace tubes in the photovoltaic industry utilizes a cleaning hook. When the suction cup has difficulty adsorbing and removing the quartz tube fragments, rotating the multi-section telescopic rod causes the fixed base to rotate, making the cleaning hook face the quartz tube fragment. Swinging the multi-section telescopic rod causes the fixed base to swing, allowing the cleaning hook to contact the inner wall of the furnace tube on the side of the quartz tube fragment away from the worker. Pulling the multi-section telescopic rod causes the cleaning hook to slide against the inner wall of the furnace tube, allowing the tip of the cleaning hook to insert between the quartz tube fragment and the inner wall of the furnace tube, thus detaching the quartz tube fragment from the inner wall of the furnace tube. This facilitates the cleaning of quartz tube fragments adhering to the inner wall of the furnace tube, improving the cleaning effect and efficiency.

[0016] 3. The tool described in this utility model for cleaning quartz fragments inside high-temperature furnace tubes in the photovoltaic industry utilizes a breaker hammer. When the quartz tube fragments are large and difficult for the suction cup to remove in one go, the multi-section telescopic rod is rotated, causing the fixed base to rotate and the breaker hammer to face the quartz tube fragments. Repeated rotation of the multi-section telescopic rod causes the fixed base to rotate repeatedly, resulting in the breaker hammer reciprocating and oscillating. The breaker hammer repeatedly strikes the quartz tube fragments, breaking large pieces into smaller pieces, thus facilitating the cleaning of the quartz tube fragments and further improving the cleaning effect and efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1 to 2 As shown, a tool for cleaning quartz fragments inside a high-temperature furnace tube in the photovoltaic industry includes a multi-section telescopic rod 1; the extended length of the multi-section telescopic rod 1 is greater than the inner length of the high-temperature furnace tube; a fixed base 2 is fixedly connected to one end of the multi-section telescopic rod 1 that extends into the high-temperature furnace tube; multiple support rods 3 are fixedly connected around the outer ring of the fixed base 2; a suction cup 4 is fixedly connected to one end of the support rod 3 away from the fixed base 2. Specifically, a disc is fixed to the inner end of the multi-section telescopic rod 1, and multiple through holes are opened around the disc; the fixing seat 2 is a cylindrical structure, and multiple screws are fixed to one side of the fixing seat 2, and the screws match the through holes on the disc, and nuts are threaded on the screws; by the cooperation of the nuts and screws, the fixing seat 2 is fixedly installed on the disc at the end of the multi-section telescopic rod 1. The outer ring of the fixed base 2 is provided with multiple screw holes 5, and both ends of the support rod 3 are provided with threads on the outer ring; one end of the support rod 3 is fixedly installed into the screw hole 5 of the outer ring of the fixed base 2 by the thread. An internally threaded cylinder is fixedly connected to the middle of the back of the suction cup 4, and the other end of the support rod 3 is threadedly fixed to the internally threaded cylinder of the suction cup 4; an air pipe connector is connected to one side of the back of the suction cup 4, and the air pipe connector can be connected to a vacuum pump via an air pipe; a sealing cap is installed on the outer thread of the air pipe connector. After the quartz tube inside the high-temperature furnace tube breaks, and the internal temperature of the furnace tube cools to room temperature, the broken quartz tube is pulled out of the furnace tube. At this time, the multi-section telescopic rod 1 is pulled and extended to extend its length, extending it into the furnace tube. This moves the fixing seat 2 to the quartz tube fragment remaining on the inner wall of the furnace tube. The suction cup 4 is then oriented towards the quartz tube fragment. The multi-section telescopic rod 1 is swung, causing the fixing seat 2 to swing, causing the suction cup 4 to press against the quartz tube fragment. Due to the pressure of the suction cup 4, the air in the groove in the middle of the suction cup 4 is expelled, creating a negative pressure that causes the suction cup 4 to attract the quartz tube fragment. At the same time, air can also be used to... The air pipe connector on the suction cup 4 is connected to a vacuum pump. When the vacuum pump is used, a vacuum negative pressure environment is created inside the suction cup 4. Then, the multi-section telescopic rod 1 is swung in the opposite direction, causing the fixed seat 2 to reset and driving the suction cup 4 to move. The suction cup 4 removes the quartz tube fragments from the inner wall of the furnace tube. The multi-section telescopic rod 1 is then pulled out of the furnace tube, and the fixed seat 2 and suction cup 4 are removed from the furnace tube. The workers then remove the quartz tube fragments adsorbed on the suction cup 4. The above cleaning process is repeated until all the quartz tube fragments inside the furnace tube are removed. This avoids the need for workers to enter the furnace tube for cleaning, which not only facilitates the cleaning work but also ensures the health of the workers.

[0022] In some embodiments, such as Figures 1 to 3 As shown, a cleaning hook 6 is fixedly connected to one end of the support rod 3 away from the fixed base 2; Specifically, the cleaning hook 6 has a hook-shaped structure, and the side of the cleaning hook 6 away from the fixing seat 2 is flat, which can fit against the inner wall of the furnace tube along the axial direction; the end of the cleaning hook 6 near the inner wall of the furnace tube and the side away from the inner wall of the furnace tube are chamfered, so that the cleaning hook 6 can slide against the inner wall of the furnace tube and be inserted between the quartz tube fragment and the inner wall of the furnace tube; the end of the cleaning hook 6 near the fixing seat 2 is fixedly connected to an internal threaded cylinder, and the internal threaded cylinder of the cleaning hook 6 is threadedly fixed to the end of the support rod 3, so that the cleaning hook 6 is fixedly installed on a support rod 3; When the suction cup 4 has difficulty adsorbing and removing the quartz tube fragments, the multi-section telescopic rod 1 is rotated, causing the fixed base 2 to rotate so that the cleaning hook 6 faces the quartz tube fragments. The multi-section telescopic rod 1 is swung, causing the fixed base 2 to swing, so that the cleaning hook 6 contacts the inner wall of the furnace tube on the side of the quartz tube fragment away from the worker. The multi-section telescopic rod 1 is pulled, causing the cleaning hook 6 to slide against the inner wall of the furnace tube, so that the tip of the cleaning hook 6 is inserted between the quartz tube fragment and the inner wall of the furnace tube, causing the quartz tube fragment to detach from the inner wall of the furnace tube. Then, the suction cup 4 is used to remove the quartz tube fragment that has detached from the inner wall of the furnace tube, or the cleaning hook 6 is used to bring the quartz tube fragment out. This makes it easier to clean the quartz tube fragments adhering to the inner wall of the furnace tube, improving the cleaning effect and efficiency.

[0023] In some embodiments, such as Figures 1 to 5As shown, a breaker hammer 7 is fixedly connected to one end of the other support rod 3 away from the fixed base 2; Specifically, the hydraulic breaker 7 has an overall elliptical columnar structure, and an internally threaded cylinder is fixedly connected to the side of the hydraulic breaker 7 near the fixed base 2. The internally threaded cylinder of the hydraulic breaker 7 is threadedly fixed to the end of the support rod 3. When the quartz tube fragments are large enough that the suction cup 4 cannot easily pick them up in one go, the multi-section telescopic rod 1 is rotated, causing the fixed base 2 to rotate, so that the breaker 7 faces the quartz tube fragments. The multi-section telescopic rod 1 is rotated repeatedly, causing the fixed base 2 to rotate repeatedly, causing the breaker 7 to swing back and forth. The breaker 7 repeatedly strikes the quartz tube fragments, breaking the large quartz tube fragments into smaller pieces. Then, the suction cup 4 and cleaning hook 6 are used to remove the quartz tube fragments, which further facilitates the cleaning of the quartz tube fragments and further improves the cleaning effect and efficiency.

[0024] Furthermore, such as Figures 1 to 5 As shown, a cone seat 8 is fixedly connected to the middle of the side of the breaker hammer 7 away from the fixed seat 2; Specifically, the breaker 7 has a threaded hole in the middle of the side away from the fixed seat 2; the cone seat 8 includes a threaded post that matches the threaded hole, and a cone is fixedly connected to the end of the threaded post away from the breaker 7. A convex ring is fixedly connected to the outer ring of the cone, and an anti-slip groove is provided around the outer ring of the convex ring. When the quartz tube fragments are large enough that the suction cup 4 cannot pick them up in one go, the multi-section telescopic rod 1 is rotated, which drives the fixed base 2 to rotate, so that the breaker 7 faces the quartz tube fragments. The multi-section telescopic rod 1 is swung, which causes the fixed base 2 to swing, and the breaker 7 to swing. This causes the cone of the cone seat 8 to hit the large quartz tube fragments, causing the large quartz tube fragments to crack and break, thereby improving the breaking efficiency of the quartz tube fragments.

[0025] In some embodiments, such as Figure 1 , Figures 6 to 8 As shown, it also includes a fixing ring 9; the fixing ring 9 can be fixedly connected to the flange of the furnace tube port; a vertical rod 10 is fixedly connected to the middle of the fixing ring 9; a lifting cylinder 11 is slidably installed on the outer ring of the vertical rod 10; a support rod 12 is fixedly connected to one side of the lifting cylinder 11; and an open lifting ring 13 is rotatably installed at the bottom end of the support rod 12. Specifically, the size of the retaining ring 9 matches the size of the flange at the furnace tube port. Multiple countersunk holes 14 are provided around the retaining ring 9, and the countersunk holes 14 correspond to the threaded holes on the flange. The retaining ring 9 is fixedly installed on the flange at the furnace tube port by passing countersunk screws through the countersunk holes 14 and threading them into the threaded holes on the flange, so that the inner ring of the retaining ring 9 is aligned with the inner ring of the furnace tube. Both ends of the upright 10 are fixed with inserts, and the inserts match the inner ring of the fixing ring 9; the inserts at both ends of the upright 10 are fixed and locked to the fixing ring 9 by screws, so that the upright 10 remains vertical. A threaded through hole is provided on the side of the lifting cylinder 11 away from the support rod 12. The threaded through hole penetrates the side wall of the lifting cylinder 11, and a locking screw 15 is installed inside the threaded through hole. By engaging the locking screw 15 with the threaded through hole, the locking screw 15 presses against the outer wall of the upright rod 10, thereby fixing and locking the lifting cylinder 11 to the upright rod 10, and thus adjusting the height of the lifting cylinder 11. The support rod 12 has a rotating ring groove at the end away from the lifting cylinder 11; the open lifting ring 13 includes a rotating cylinder that is rotatably connected to the rotating ring groove, and a semi-circular ring hook is fixed to the bottom end of the rotating cylinder. When it is necessary to clean the quartz tube fragments remaining on the inner wall of the furnace tube, use countersunk screws to thread them through the countersunk hole 14 and into the threaded hole on the flange to fix the retaining ring 9 to the flange at the furnace tube port. Push the lifting cylinder 11 to slide up and down along the upright 10, adjust the open lifting ring 13 to a suitable height, and turn the locking screw 15 to fix and lock the lifting cylinder 11 to the upright 10. After the multi-section telescopic rod 1 is extended, place it on the open lifting ring 13. The open lifting ring 13 serves as the fulcrum for the swing and rotation of the multi-section telescopic rod 1, thereby effectively reducing the difficulty of operation for workers and improving the cleaning efficiency.

[0026] Furthermore, such as Figure 1 , Figures 6 to 8 As shown, a positioning cylinder 16 is rotatably mounted on the bottom of the lifting cylinder 11; the positioning cylinder 16 is slidably mounted on the outer ring of the upright 10. Specifically, the bottom outer ring of the lifting cylinder 11 is provided with an annular groove, the top of the positioning cylinder 16 is rotatably engaged with the annular groove at the bottom of the lifting cylinder 11, the outer ring of the positioning cylinder 16 is provided with multiple threaded holes, and the internal threads of the threaded holes are fitted with threaded columns. The positioning cylinder 16 is fixed and locked to the outer ring of the upright 10 by pressing against the outer wall of the upright 10 through the threaded columns. After the lifting cylinder 11 is adjusted to the appropriate height of the upright 10, the lifting cylinder 11 is locked with the locking screw 15; then the positioning cylinder 16 is locked and fixed to the upright 10 with the threaded column, thereby improving the locking firmness of the lifting cylinder 11; when it is necessary to adjust the position of the support rod 12 and the open lifting ring 13, the locking screw 15 is rotated in the opposite direction to loosen the lifting cylinder 11. Due to the obstruction of the positioning cylinder 16, the lifting cylinder 11 is kept at the same height. The lifting cylinder 11 is rotated to adjust the direction and position of the support rod 12 and the open lifting ring 13, thereby facilitating the cleaning of quartz tube fragments in different positions.

[0027] Furthermore, such as Figure 1As shown, the outer and inner walls of each section of the multi-section telescopic rod 1 are threaded. Specifically, each section of the multi-section telescopic rod 1 has threads on its inner and outer walls. The threads on the inner and outer walls of two adjacent sections of the multi-section telescopic rod 1 can be threaded together. This allows the threaded connection between adjacent sections to be fixed after the multi-section telescopic rod 1 is extended, thereby improving the stability of the multi-section telescopic rod 1 after extension and ensuring the effectiveness of the swing and rotation of the operating fixed seat 2, and thus ensuring the cleaning effect of quartz tube fragments.

[0028] Working principle: After the quartz tube inside the high-temperature furnace tube breaks, the internal temperature of the furnace tube cools down to room temperature. The broken quartz tube is then pulled out of the furnace tube. A countersunk screw is used to thread it through the countersunk hole 14 and into the threaded hole on the flange. The fixing ring 9 is then fixedly installed on the flange at the furnace tube port. The lifting cylinder 11 is pushed to slide up and down along the upright 10. The open lifting ring 13 is adjusted to a suitable height. The locking screw 15 is rotated to fix the lifting cylinder 11 to the upright 10. The positioning cylinder 16 is then locked to the upright 10 using a threaded post. This improves the locking firmness of the lifting cylinder 11. When it is necessary to adjust the position of the support rod 12 and the open lifting ring 13, the locking screw 15 is rotated in the opposite direction to loosen the lifting cylinder 11. Due to the obstruction of the positioning cylinder 16, the lifting cylinder 11 remains at the same height. The lifting cylinder 11 is then rotated to adjust the direction and position of the support rod 12 and the open lifting ring 13. After the multi-section telescopic rod 1 is extended, it is placed on the open lifting ring 13. The multi-section telescopic rod 1 is then inserted into the furnace tube, causing the fixing seat 2 to move to the quartz tube fragment remaining on the inner wall of the furnace tube. The suction cup 4 is then oriented towards the quartz tube fragment. The multi-section telescopic rod 1 is swung, causing the fixing seat 2 to swing, which causes the suction cup 4 to press against the quartz tube fragment. Due to the pressure from the suction cup 4, the air in the groove in the middle of the suction cup 4 is expelled, creating a negative pressure that causes the suction cup 4 to adhere to the quartz tube fragment. Then, the multi-section telescopic rod 1 is swung in the opposite direction, causing the fixing seat 2 to return to its original position and moving the suction cup 4. The suction cup 4 then removes the quartz tube fragment from the inner wall of the furnace tube. The multi-section telescopic rod 1 is then pulled out of the furnace tube, and the fixing seat 2 and suction cup 4 are removed from the furnace tube. The operator then removes the quartz tube fragment adsorbed on the suction cup 4. When the suction cup 4 has difficulty adsorbing and removing the quartz tube fragment, at this time, rotate the multi-section telescopic rod 1 to drive the fixed base 2 to rotate, so that the cleaning hook 6 is facing the quartz tube fragment. Swing the multi-section telescopic rod 1 to make the fixed base 2 swing, so that the cleaning hook 6 contacts the inner wall of the furnace tube on the side of the quartz tube fragment away from the worker. Pull the multi-section telescopic rod 1 to drive the cleaning hook 6 to slide against the inner wall of the furnace tube, so that the tip of the cleaning hook 6 is inserted between the quartz tube fragment and the inner wall of the furnace tube, and drives the quartz tube fragment to detach from the inner wall of the furnace tube. When the quartz tube fragments are large enough that the suction cup 4 cannot pick them up in one go, the multi-section telescopic rod 1 is rotated, which drives the fixed base 2 to rotate, so that the breaker 7 faces the quartz tube fragments. The multi-section telescopic rod 1 is rotated repeatedly, which drives the fixed base 2 to rotate repeatedly, which drives the breaker 7 to swing back and forth. The breaker 7 is used to repeatedly strike the quartz tube fragments, breaking the large quartz tube fragments into smaller pieces. Then, the suction cup 4 and the cleaning hook 6 are used to remove the quartz tube fragments. Repeat the cleaning process described above until all the quartz tube fragments inside the furnace tube are removed; this avoids the need for workers to enter the furnace tube for cleaning, which not only facilitates the cleaning work but also ensures the health of the workers.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
