Description

Technical Field

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

[0002] High-temperature furnace tubes in the photovoltaic industry are core equipment for depositing silicon nitride antireflective films and polycrystalline silicon layers in photovoltaic cell manufacturing. They are mainly used in high-temperature deposition, sintering, annealing and other processes, and their performance directly affects production efficiency and cell quality.

[0003] High-temperature furnace tubes need to operate continuously at 400-1100℃. During the transport of silicon wafers, about 3%-5% of the fragments generated by mechanical vibration or thermal stress breakage will fall deep into the furnace tube. If the fragments are not cleaned in time, they will accumulate inside the tube, causing short circuits between the fragments and the silicon wafers in the graphite boat, preventing the formation of a discharge circuit and leading to process failure. It will also cause uneven coating. Too many fragments will lead to uneven temperature in the heating zone, resulting in poor coating color. Therefore, it is necessary to clean the fragments inside the furnace tube in a timely manner to ensure the cleanliness of the furnace tube.

[0004] Due to the large length of the high-temperature furnace tubes, the debris located at the tail end of the tubes is difficult to clean deeply by hand with a brush. This poses a risk of damage to the tubes and also presents safety hazards for workers when cleaning debris directly from the tubes at higher elevations.

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

A fixed seat is sleeved at the end of the cantilever paddle. Multiple spring telescopic rods are uniformly fixed to the bottom of the fixed seat. A mounting plate is fixed to the bottom of the multiple spring telescopic rods. Multiple brush strips are provided on the bottom surface of the mounting plate.

[0008] Preferably, the bottom outer ring of the fixed base is provided with an arc-shaped sliding groove; the bottom side of the fixed base away from the cantilever propeller is provided with a stepped groove; a baffle is bolted inside the stepped groove; a rotating ring is slidably installed inside the arc-shaped sliding groove; and the top of the spring telescopic rod is fixedly connected to the outer wall of the rotating ring.

[0009] Preferably, an arc-shaped protrusion is fixedly connected to the center of the side of the arc-shaped groove that is close to the baffle; an annular groove is provided on both sides of the rotating ring; the arc-shaped protrusion slides in conjunction with the annular groove.

[0010] Preferably, both ends of the arc-shaped groove are provided with inner cavities; the inner cavities penetrate the side wall of the fixed seat; an internal gear ring is fixedly connected to the inner ring of the rotating ring; a drive gear is rotatably installed in the middle of one side of the inner cavity; the drive gear meshes with the internal gear ring; a rotating rod is fixedly connected to the middle of the drive gear; the rotating rod rotatably penetrates the outer wall of the fixed seat.

[0011] Preferably, a limiting gear is rotatably installed in the middle of the inner cavity on the other side; the limiting gear meshes with the internal gear ring; a tapered hole is opened in the middle of the side of the limiting gear away from the baffle; a pointed screw is slidably arranged inside the tapered hole; the pointed screw penetrates the outer wall of the fixed seat, and the pointed screw is threadedly engaged with the fixed seat.

[0012] Preferably, both sides of the drive gear and both sides of the limiting gear are provided with limiting ring grooves; the side of the inner cavity that is close to the baffle is fixedly connected with a limiting protrusion; the limiting protrusion and the limiting ring groove are rotatably engaged.

[0014] Preferably, the bottom surface of the mounting plate is provided with a plurality of clamping strips; a bristle strip is clamped and fixed between two adjacent clamping strips.

[0015] The advantages of this utility model are: 1. This utility model discloses a tool for cleaning debris inside high-temperature furnace tubes in the photovoltaic industry. It comprises a cantilever paddle, a fixed base, a spring telescopic rod, a mounting plate, and brush strips. The cantilever paddle is controlled to rise to its upper limit, extending into the interior of the high-temperature furnace tube. This causes the brush strips to move to the tail end of the furnace tube, specifically to the side where debris is furthest from the opening. The cantilever paddle then descends to its lower limit, bringing the brush strips into contact with the bottom of the furnace tube. This causes the spring telescopic rod to retract, and the spring force within the rod compresses the brush strips, keeping them firmly against the bottom of the furnace tube. Finally, the cantilever paddle moves out of the furnace tube, causing the brush strips to slide out while still attached to the bottom, carrying away the accumulated debris. This facilitates cleaning the interior of the high-temperature furnace tube, avoids the dangers of direct cleaning by workers, and reduces damage to the furnace tube.

[0016] 2. The tool described in this utility model for cleaning debris inside high-temperature furnace tubes in the photovoltaic industry comprises a rotating ring, an internal gear ring, a drive gear, and a rotating rod. The drive rod drives the drive gear to rotate, and the drive gear meshes with the internal gear ring, causing the internal gear ring to rotate, which in turn drives the rotating ring to rotate. This causes the brush strips to rotate and adjust their orientation, allowing the brush strips to contact the debris and impurities adhering to the inner wall of the high-temperature furnace tube. The cantilever paddle is controlled to move axially back and forth, driving the brush strips to move back and forth, thus cleaning the debris and impurities adhering to the inner wall of the high-temperature furnace tube. The debris and impurities fall to the bottom of the high-temperature furnace tube, and then the debris and impurities at the bottom of the high-temperature furnace tube are cleaned, thereby improving the comprehensiveness of cleaning the inside of the high-temperature furnace tube.

[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 debris inside high-temperature furnace tubes in the photovoltaic industry includes a cantilever paddle 1 capable of precisely transferring silicon wafers inside the high-temperature furnace tube. A fixed base 2 is sleeved at the end of the cantilever paddle 1. Multiple spring telescopic rods 3 are uniformly fixed to the bottom of the fixed base 2. A mounting plate 4 is fixed to the bottom of the multiple spring telescopic rods 3. Multiple brush strips 5 are provided on the bottom surface of the mounting plate 4. Specifically, the cross-section of the cantilever propeller 1 is a U-shaped structure, the two side walls of the cantilever propeller 1 are inclined to both sides, and the top of the two side walls of the cantilever propeller 1 is provided with protruding strips on the outer side; the cantilever propeller 1 can extend into and out of the interior of the high-temperature furnace tube, and can rise and fall in different heights. The outer ring of the fixed base 2 is a semi-circular structure, and both sides are vertical sides; the middle of the fixed base 2 is provided with a U-shaped groove that matches the cantilever propeller 1, and the top two sides of the U-shaped groove are provided with slots, which slide in cooperation with the protrusions on both sides of the cantilever propeller 1. The top of both sides of the fixed base 2, and the top of the slot, are provided with threaded holes, and locking screws 6 are installed inside the threads of the threaded holes; by pressing the top surface of the protrusion of the cantilever propeller 1 with the locking screws 6, the fixed base 2 and the cantilever propeller 1 are fixed and locked. The spring telescopic rod 3 includes an outer cylinder, a sliding rod is slidably installed inside the outer cylinder, and a spring is fixed between the outer cylinder and the sliding rod; the spring force pushes the sliding rod to slide out from inside the outer cylinder; and, due to the cooperation between the outer cylinder and the sliding rod, the movement direction of the mounting plate 4 is ensured, and the stability of the mounting plate 4 is improved. Mounting plate 4 has an arc-shaped structure and matches the curvature of the inner wall of the high-temperature furnace tube; the brush strip 5 is made of PC material, which makes the brush bristles of the brush strip 5 less likely to fall off, thus avoiding secondary pollution to the inside of the high-temperature furnace tube. When debris accumulates inside the high-temperature furnace tube, it needs to be cleaned. The debris will fall to the bottom of the high-temperature furnace tube. Align the U-shaped groove of the fixing seat 2 with the cantilever paddle 1, and slide the fixing seat 2 to the outer end of the cantilever paddle 1. Control the cantilever paddle 1 to rise to the upper limit. At this time, the spring telescopic rod 3 is in the extended state, and the brush strip 5 at the bottom of the mounting plate 4 is not in contact with the inner wall of the high-temperature furnace tube. Control the cantilever paddle 1 to extend into the interior of the high-temperature furnace tube, driving the fixing seat 2, spring telescopic rod 3, mounting plate 4, and brush strip 5 to move to the tail of the high-temperature furnace tube, i.e., at the location of the debris. The impurities are far from the opening side of the high-temperature furnace tube. At this time, the cantilever paddle 1 descends to the lower limit, causing the brush strip 5 to contact the bottom of the high-temperature furnace tube. This causes the spring telescopic rod 3 to retract, and the elastic force generated by the compression of the spring inside the spring telescopic rod 3 pushes the brush strip 5 to always keep it in close contact with the bottom of the high-temperature furnace tube. The cantilever paddle 1 is controlled to move out of the high-temperature furnace tube, causing the brush strip 5 to slide out of the high-temperature furnace tube while still in contact with the bottom of the high-temperature furnace tube, thus carrying away the accumulated debris and impurities. This facilitates the cleaning of the inside of the high-temperature furnace tube, avoids the danger of direct cleaning by personnel, and reduces damage to the high-temperature furnace tube.

[0022] In some embodiments, such as Figures 1 to 4 As shown, the bottom outer ring of the fixed base 2 is provided with an arc-shaped sliding groove 7; the bottom of the fixed base 2 away from the cantilever propeller 1 is provided with a stepped groove 8; a baffle 9 is bolted inside the stepped groove 8; a rotating ring 10 is slidably installed inside the arc-shaped sliding groove 7; the top of the spring telescopic rod 3 is fixedly connected to the outer wall of the rotating ring 10. Specifically, the curvature of the arc-shaped slide 7 is the same as that of the outer ring at the bottom of the fixed base 2; the stepped groove 8 is connected to the arc-shaped slide 7, and multiple screw holes are evenly provided on one side of the stepped groove 8 near the middle of the fixed base 2. The baffle 9 is provided with a through hole that matches the screw hole on the stepped groove 8. The baffle 9 is fixedly installed in the stepped groove 8 by threading screws through the through hole and the screw hole, so that the baffle 9 blocks one side of the arc-shaped slide 7; the curvature of the rotating ring 10 is the same as that of the arc-shaped slide 7. The rotating ring 10 is rotated and installed into the arc-shaped slide 7 by the cooperation of the baffle 9 with the inner side wall of the arc-shaped slide 7. A small amount of debris and impurities will adhere to the tube wall inside the high-temperature furnace tube. At this time, rotating the rotating ring 10 causes it to slide and rotate along the inside of the arc-shaped groove 7, driving the spring telescopic rod 3, the mounting plate 4, and the brush strip 5 to rotate, so that the brush strip 5 faces the debris and impurities adhering to the inner wall of the high-temperature furnace tube. Then, the cantilever paddle 1 is inserted into the high-temperature furnace tube, and the height of the cantilever paddle 1 is adjusted so that the brush strip 5 contacts the debris and impurities adhering to the inner wall of the high-temperature furnace tube. The cantilever paddle 1 is controlled to move axially back and forth, driving the brush strip 5 to move back and forth, cleaning the debris and impurities adhering to the inner wall of the high-temperature furnace tube from the inner wall of the high-temperature furnace tube, so that the debris and impurities fall to the bottom of the high-temperature furnace tube. Then, the debris and impurities at the bottom of the high-temperature furnace tube are cleaned, thereby improving the comprehensiveness of the cleaning of the inside of the high-temperature furnace tube.

[0023] Furthermore, in some embodiments, such as Figures 2 to 6 As shown, an arc-shaped protrusion 11 is fixedly connected to the center of the side of the arc-shaped groove 7 that is close to the baffle 9; an annular groove 12 is provided on both sides of the rotating ring 10; the arc-shaped protrusion 11 and the annular groove 12 are slidably engaged. Specifically, by slidingly engaging the arc-shaped protrusion 11 with the annular grooves 12 on both sides of the rotating ring 10, the rotation of the rotating ring 10 is not only guided, enabling the rotating ring 10 to maintain stable rotation, but also the rotating ring 10 is fixed in the arc-shaped groove 7, preventing the rotating ring 10 from detaching from the arc-shaped groove 7.

[0024] In some embodiments, such as Figures 2 to 5 As shown, both ends of the arc-shaped groove 7 are provided with inner cavities 13; the inner cavity 13 penetrates the side wall of the fixed base 2; the inner ring of the rotating ring 10 is fixedly connected to an internal gear ring 14; a drive gear 15 is rotatably installed in the middle of one side of the inner cavity 13; the drive gear 15 is not meshed with the internal gear ring 14; a rotating rod 16 is fixedly connected to the middle of the drive gear 15; the rotating rod 16 rotatably penetrates the outer wall of the fixed base 2. Specifically, the inner cavity 13 has a circular structure and is located at both ends of the arc-shaped groove 7; the two ends of the baffle 9 can cover the inner cavity 13; a circular hole is opened in the middle of the side of the inner cavity 13 away from the baffle 9, and the rotating rod 16 is rotatably installed in the circular hole, and an internal hexagon head is fixed to one end of the rotating rod 16 located outside the inner cavity 13. The inner ring of the rotating ring 10 has an annular groove, and the drive gear 15 is fixedly connected in the annular groove of the inner ring of the rotating ring 10. When it is necessary to adjust the orientation of the brush strip 5 to clean debris and impurities adhering to the inner wall of the high-temperature furnace tube, use a hex wrench inserted into the internal hex head of the rotating rod 16 to drive the rotating rod 16 to rotate, which in turn drives the drive gear 15 to rotate. Through the meshing of the drive gear 15 with the internal gear ring 14, the drive gear 15 drives the internal gear ring 14 to rotate, which in turn drives the rotating ring 10 to rotate, thus rotating the brush strip 5 to adjust its orientation. This makes it easier for workers to adjust the orientation of the brush strip 5, improving the convenience and accuracy of the adjustment.

[0025] In some embodiments, such as Figures 2 to 6 As shown, a limiting gear 17 is rotatably installed in the middle of the inner cavity 13 on the other side; the limiting gear 17 meshes with the internal gear ring 14; a tapered hole 18 is provided in the middle of the side of the limiting gear 17 away from the baffle 9; a pointed screw 19 is slidably disposed inside the tapered hole 18; the pointed screw 19 penetrates the outer wall of the fixed seat 2, and the pointed screw 19 is threadedly engaged with the fixed seat 2; Specifically, a screw hole is provided in the middle of the inner cavity 13 near the limit gear 17 on the side away from the baffle 9; one end of the pointed screw 19 has a pointed structure, the outer ring of the middle part of the pointed screw 19 has a thread, and the other end of the pointed screw 19 is fixed with an internal hexagon head; the thread of the outer ring of the middle part of the pointed screw 19 is engaged with the thread of the screw hole. The drive gear 15 drives the internal gear ring 14 to rotate, which in turn drives the rotating ring 10 and the bristle strip 5 to rotate. At the same time, the internal gear ring 14 drives the limiting gear 17 to rotate. When the orientation of the bristle strip 5 is adjusted, a hex wrench is used to rotate the pointed screw 19. Since the pointed screw 19 is threaded into the screw hole, it rotates and moves into the inner cavity 13. The pointed tip of the pointed screw 19 is inserted into the tapered hole 18 of the limiting gear 17. The outer wall of the pointed tip of the pointed screw 19 presses against the inner wall of the tapered hole 18, fixing and locking the limiting gear 17. Since the limiting gear 17 meshes with the internal gear ring 14, the internal gear ring 14 is locked in place after the limiting gear 17 is locked. This prevents the rotating ring 10 from rotating accidentally, causing the bristle strip 5 to move and thus affecting the cleaning effect.

[0026] Furthermore, such as Figures 2 to 6 As shown, both sides of the drive gear 15 and both sides of the limiting gear 17 are provided with limiting ring grooves 20; the inner cavity 13 and the side close to the baffle 9 are fixedly connected with limiting protrusions 21; the limiting protrusions 21 and the limiting ring grooves 20 are rotatably engaged. Specifically, by slidingly engaging the limiting protrusion 21 with the limiting ring groove 20, the drive gear 15 and the limiting gear 17 are respectively fixedly installed in the inner cavities 13 on both sides, thereby ensuring the stability of the drive gear 15 and the limiting gear 17 during operation, and thus improving the stability of the rotating ring 10 during rotation and the firmness of the fixed position.

[0027] In some embodiments, such as Figures 1 to 2 As shown, the outer ring of the rotating ring 10 has multiple planar mounting positions 22; the spring telescopic rod 3 can be fixedly installed on the mounting positions 22; Specifically, the multiple mounting positions 22 facilitate the installation of spring telescopic rods 3; at the same time, multiple sets of spring telescopic rods 3, mounting plates 4 and brush strips 5 can be installed on the outer ring of the rotating ring 10. By setting multiple sets of brush strips 5, it is convenient to clean debris and impurities at different locations on the inner wall of the high-temperature furnace tube, thus improving the cleaning effect.

[0028] In some embodiments, such as Figures 7 to 9 As shown, the bottom surface of the mounting plate 4 is provided with a plurality of clamping strips 23; a bristle strip 5 is clamped and fixed between two adjacent clamping strips 23; Specifically, a protruding plate is fixed to one bottom side of the mounting plate 4, and square rods are fixed to the bottom of both ends of the protruding plate, forming a channel between the square rods and the mounting plate 4. Guide rods 24 are fixed to the top of both ends of the protruding plate, and the guide rods 24 are located in the middle of the channel. The outer ring of the guide rod 24 away from the protruding plate is threaded, and a nut is installed on the outer ring of the guide rod 24 away from the protruding plate. The shape of the clamping strip 23 matches the shape of the bottom surface of the mounting plate 4, so that the clamping strip 23 can fit against the bottom surface of the mounting plate 4; both ends of the clamping strip 23 can slide through the channels at both ends of the mounting plate 4, and the clamping strip 23 has sliding holes at both ends, through which the guide rod 24 slides. By engaging the nut with the threaded connection of the outer ring of the guide rod 24, multiple clamping strips 23 are pushed closer together, and two adjacent clamping strips 23 are brought closer together to clamp and fix the bristle strip 5. By fixing each bristle strip 5 independently, the probability of the bristle strip 5 falling off is reduced, and it is also convenient to replace the damaged bristle strip 5.

[0029] Working principle: When it is necessary to clean the inside of the high-temperature furnace tube, align the U-shaped groove of the fixed seat 2 with the cantilever paddle 1, and slide the fixed seat 2 to the outer end of the cantilever paddle 1. Insert a hex wrench into the internal hex head of the rotating rod 16 to drive the rotating rod 16 to rotate, which in turn drives the drive gear 15 to rotate. Through the meshing of the drive gear 15 with the internal gear ring 14, the drive gear 15 drives the internal gear ring 14 to rotate, which in turn drives the rotating ring 10 to rotate, which in turn drives the brush strip 5 to rotate and adjust its orientation so that the brush strip 5 faces the debris and impurities adhering to the inner wall of the high-temperature furnace tube. At this time, use a hex wrench to rotate the pointed screw 19. Since the pointed screw 19 is threaded with the screw hole, the pointed screw 19 rotates and moves into the inner cavity 13. The pointed tip of the pointed screw 19 is inserted into the tapered hole 18 of the limiting gear 17. The outer wall of the pointed tip of the pointed screw 19 presses against the inner wall of the tapered hole 18, fixing and locking the limiting gear 17. Since the limiting gear 17 meshes with the internal gear ring 14, after the limiting gear 17 is fixed and locked, the internal gear ring 14 will be locked and fixed, and the orientation of the brush strip 5 will be fixed and locked. Next, extend the cantilever paddle 1 into the high-temperature furnace tube and adjust the height of the cantilever paddle 1 so that the brush strip 5 contacts the debris and impurities adhering to the inner wall of the high-temperature furnace tube. Control the cantilever paddle 1 to move axially back and forth, driving the brush strip 5 to move back and forth, cleaning the debris and impurities adhering to the inner wall of the high-temperature furnace tube from the inner wall of the high-temperature furnace tube, so that the debris and impurities fall to the bottom of the high-temperature furnace tube. Then, move the cantilever paddle 1 out of the high-temperature furnace tube, rotate the pointed screw 19 in the opposite direction to loosen and release the limiting gear 17 and the internal gear ring 14; then rotate the rotating rod 16 to drive the drive gear 15 to rotate, which in turn drives the internal gear ring 14 and the rotating ring 10 to rotate, so that the brush strip 5 is vertically downward; then rotate the pointed screw 19 to lock and fix the limiting gear 17 and the internal gear ring 14. Then, the cantilever paddle 1 is raised to its upper limit. At this point, the spring telescopic rod 3 is extended, and the brush strip 5 at the bottom of the mounting plate 4 is not in contact with the inner wall of the high-temperature furnace tube. The cantilever paddle 1 is then inserted into the high-temperature furnace tube, moving the fixed base 2, spring telescopic rod 3, mounting plate 4, and brush strip 5 to the tail of the high-temperature furnace tube, i.e., the side where the debris and impurities are far from the opening of the high-temperature furnace tube. At this point, the cantilever paddle 1 is lowered to its lower limit, causing the brush strip 5 to contact the bottom of the high-temperature furnace tube. This causes the spring telescopic rod 3 to retract, and the elastic force generated by the compression of the spring inside the spring telescopic rod 3 pushes the brush strip 5 to remain firmly against the bottom of the high-temperature furnace tube. The cantilever paddle 1 is then moved out of the high-temperature furnace tube, causing the brush strip 5 to slide out of the high-temperature furnace tube while still attached to the bottom, thus carrying away the accumulated debris and impurities. This facilitates the cleaning of the inside of the high-temperature furnace tube, avoids the dangers of direct cleaning by personnel, and reduces damage to the high-temperature furnace tube.

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.
