Description

A multi-flame longitudinal combustion device for processing quartz fiber materials Technical Field

[0001] This utility model relates to the field of quartz fiber technology, specifically to a multi-flame longitudinal combustion device for processing quartz fiber materials. Background Technology

[0002] Quartz fiber is a fiber made from high-purity silicon dioxide and natural quartz crystals. It possesses heat resistance, corrosion resistance, and flexibility. It exhibits high strength retention at high temperatures, dimensional stability, thermal shock resistance, chemical stability, good light transmittance, and good electrical insulation. During processing, quartz fiber requires combustion before it can be processed.

[0003] However, current burners often have only one nozzle, resulting in a small combustion area, which in turn affects the efficiency of combustion and is not conducive to the processing of quartz fibers. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-flame longitudinal combustion device for processing quartz fiber materials.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A multi-flame longitudinal combustion device for processing quartz fiber materials includes a housing. A rotatable bidirectional lead screw is installed inside the housing. A fixed block is rotatably mounted in the middle of the bidirectional lead screw and is fixed within the housing. Two movable blocks, located on either side of the fixed block, are threaded onto the bidirectional lead screw. A rotatable threaded rod is installed within each movable block. A limit block is rotatably mounted at one end of the threaded rod, and a threaded block is threaded onto the threaded rod. A fixing plate for mounting nozzles is fixed to one end of each of the limit block, threaded block, and fixed block. Multiple nozzles are arranged longitudinally in two rows. A combustion mechanism for feeding materials is also provided on the housing. The combustion mechanism is connected to the nozzles via a pre-reserved flexible hose.

[0007] Preferably, the two rows of nozzles are arranged in a staggered manner.

[0008] Preferably, the limiting blocks are all rotatably mounted on the end of the threaded rod near the fixed block.

[0009] Preferably, the moving blocks are all L-shaped, and the inner angles of the two moving blocks are facing each other.

[0010] Preferably, each of the movable blocks is equipped with a drive motor, and the drive motor is connected to the end of the threaded rod away from the fixed block.

[0011] Preferably, the top of the housing is rotatably provided with a turntable that penetrates the housing and is fixedly connected to a bidirectional lead screw.

[0012] Preferably, the front and rear sides of the housing are provided with sliding grooves, and the front and rear ends of the moving block are fixed with sliding plates that are slidably connected to the sliding grooves.

[0013] Preferably, the combustion mechanism includes an oxygen tank and a fuel tank located on both sides of the housing, and a mixing tank located at the bottom of the housing. The oxygen tank and the fuel tank are connected to the mixing tank through pipes, and the mixing tank is connected to the nozzle through a hose.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model improves combustion efficiency by using multiple nozzles. By using two rows of nozzles, the distance between two adjacent nozzles in the same row can be increased while ensuring complete combustion. At the same time, the two rows can increase the combustion area, and the combined effect improves combustion efficiency, thereby increasing practical value.

[0016] 2. This utility model uses the rotation of a bidirectional lead screw to drive two moving blocks to move in opposite directions, thereby adjusting the distance between the nozzle on the limiting block and the nozzle on the fixed block. The rotation of the threaded rod drives the threaded block to move, thereby adjusting the distance between the nozzle on the threaded block and the nozzle on the limiting block, thus ensuring that the distance between two adjacent nozzles in the vertical direction is equal.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] As shown in Figure 1, a multi-flame longitudinal combustion device for processing quartz fiber materials according to this utility model includes a housing 1. An oxygen tank 3 and a fuel tank 4 are respectively arranged on both sides of the housing 1. A mixing box is also arranged at the bottom of the housing 1. The oxygen tank 3 and the fuel tank 4 are connected to the mixing box through pipes. A turntable 2 is rotatably arranged at the top of the housing 1, and the turntable 2 passes through the housing 1. A bidirectional lead screw 6 located inside the housing 1 is fixed at the bottom of the turntable 2. A fixed block 7 is rotatably arranged in the middle of the bidirectional lead screw 6 and is fixed inside the housing 1. Two moving blocks 8 are respectively located on both sides of the fixed block 7 with mirror threads on the bidirectional lead screw 6. By rotating the turntable 2, the two moving blocks 8 are driven to move in opposite directions on the bidirectional lead screw 6, thereby changing the distance between the moving blocks 8 and the fixed block 7. As shown in Figure 2, sliding grooves 5 are opened on both the front and rear sides of the housing 1. Sliding plates 10 that are slidably connected to the sliding grooves 5 are fixed at both the front and rear ends of the moving blocks 8 to ensure that the moving blocks 8 do not rotate when the bidirectional lead screw 6 rotates, thereby ensuring the stability of the moving blocks 8 in raising and lowering.

[0027] As shown in Figure 3, the movable blocks 8 are all L-shaped, and the included angles of the two movable blocks 8 are set towards each other, so that the part of the movable block 8 connected to the bidirectional lead screw 6 is the end away from the fixed block 7. The side of the movable block 8 away from the fixed block 7 is equipped with a drive motor 9, as shown in Figure 4. The output end of the drive motor 9 is equipped with a threaded rod 15 located inside the movable block 8. The end of the threaded rod 15 near the fixed block 7 is rotatably equipped with a limit block 13, and the threaded rod 15 is threaded with threaded blocks 11. The threaded blocks 11 all pass through the movable block 8 and are slidably connected to the movable block 8. The limit block 13 is rotatably set on the end of the threaded rod 15 near the fixed block 7 so that when the bidirectional lead screw 6 rotates, it directly adjusts the distance between the limit block 13 and the fixed block 7. Then, the drive motor 9 drives the threaded rod 15 to rotate and adjust the distance between the threaded block 11 and the limit block 13, thereby ensuring that the distances between the two adjacent threaded blocks 11, the limit block 13 and the fixed block 7 are equal.

[0028] As shown in Figures 3 and 4, a fixing plate 12 is fixed to one end of the limiting block 13, the threaded block 11, and the fixing block 7. A nozzle 14 is installed on the fixing plate 12. Two through holes for raising and lowering the nozzle 14 are opened on the front side of the housing 1, and there is a gap between the through holes and the nozzle 14 to avoid the friction caused by contact affecting the service life of the nozzle 14. Multiple nozzles 14 are arranged longitudinally in two rows, and the two rows of nozzles 14 are staggered. The staggered arrangement of the two rows of nozzles 14 improves the combustion efficiency on the one hand, and increases the spacing between adjacent nozzles 14 in the same row while ensuring complete combustion. At the same time, the two rows can increase the combustion area, and together improve the combustion efficiency, thereby increasing the practical value. One end of the nozzle 14 is connected to the mixing box through a hose, and the hose has a reserved length to ensure the stability of the raising and lowering of the nozzle 14. The combustion mechanism composed of oxygen tank 3, fuel tank 4 and mixing box sprays fuel to the nozzle 14, thereby ensuring the stability of the combustion operation.

[0029] In use, the rotation of the bidirectional lead screw 6 drives the two moving blocks 8 to move in opposite directions, thereby adjusting the distance between the nozzle 14 on the limiting block 13 and the nozzle 14 on the fixed block 7. The rotation of the threaded rod 15 drives the threaded block 11 to move, thereby adjusting the distance between the nozzle 14 on the threaded block 11 and the nozzle 14 on the limiting block 13. This ensures that the distance between two adjacent nozzles 14 in the vertical direction is equal. The nozzles 14 are used for combustion. The size of the flame emitted by the nozzles 14 is controlled by the valve to ensure that the two adjacent nozzles 14 can stably and fully burn the quartz fiber.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
