Description

Technical Field

[0001] This invention relates to the field of pressure vessel manufacturing technology, specifically a method for rapid disassembly and positioning assembly of a reduction furnace. Background Technology

[0002] Polysilicon is a core raw material for the photovoltaic industry. As an important device for producing polysilicon materials, the production efficiency and output of polysilicon reduction furnaces are particularly important for the development of enterprises.

[0003] The reduction furnace consists of a chassis assembly, a bell jar assembly, and various flange pipelines. Polycrystalline silicon raw materials are formed in the bell jar assembly through a series of chemical vapor deposition reactions. After reaching a certain quantity, the bell jar assembly is opened, the produced polycrystalline silicon material is taken out, and then the bell jar assembly is reinstalled for production again.

[0004] Because silicon rods are handled at a very high frequency, the bell jar assembly needs to be opened frequently. This necessitates improving the assembly and disassembly efficiency of the connecting bolts and nuts between the bell jar assembly and the chassis assembly, saving time, and thus increasing the production efficiency of silicon rods.

[0005] Taking the 72-pair rod reduction furnace as an example, the bell jar assembly and the chassis assembly are connected by 104 sets of bolts and nuts. The bolts are φ45mm in diameter and 1000mm in length. Each bolt weighs 10kg. Manual operation is inconvenient for disassembly and installation, and the work is arduous and inefficient.

[0006] Therefore, we propose a method for rapid disassembly and positioning assembly of a reduction furnace to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a method for rapid disassembly and positioning assembly of a reduction furnace, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for rapid disassembly and positioning assembly of a reduction furnace, comprising...

[0009] S1: Production of bell jar body, bell jar flange, chassis body, chassis flange, positioning pin, pin sleeve one, pin sleeve two, bolt, hexagonal nut and lifting ring;

[0010] S2: Weld at least three pin sleeves one onto the chassis flange and insert the locating pins into the pin sleeves one;

[0011] S3: Place the chassis body and weld the chassis flange on top of the chassis body. After the chassis flange is assembled, align the bell flange with the positioning pin and place it on the chassis flange. After adjusting and placing the bell flange, use bolts to connect the chassis flange and the bell flange. Install hexagonal nuts on both ends of the bolts and tighten them to assemble the bell body.

[0012] S4: When disassembling the bell flange, remove the hexagonal nut at the top of the bell flange;

[0013] S5: Start the cylinder under the chassis flange, and there is a base under the cylinder. The cylinder causes the lifting ring to descend, and the bolt will follow the lifting ring down to below the mating surface of the bell flange and chassis flange assembly.

[0014] S6: Lift the bell body to disengage the pin sleeve on the outer wall of the bell flange from the positioning pin, and disassemble the reduction furnace.

[0015] Furthermore, a disassembly mechanism is provided above the bell jar body, and the disassembly mechanism includes a support column fixedly connected to the base. A top plate is fixedly provided at the end of the support column away from the base, and an electric telescopic rod is fixedly provided on the bottom surface of the top plate near the center.

[0016] The above structural design, utilizing support columns and a top plate, facilitates the support of the electric telescopic pole, thereby improving its stability during operation.

[0017] Furthermore, a connecting rod is fixedly provided at the output end of the electric telescopic rod, and a support plate is fixedly provided at the end of the connecting rod away from the electric telescopic rod. A fixed telescopic rod is fixedly provided on the bottom surface of the support plate, and an electromagnetic suction is fixedly provided at the end of the fixed telescopic rod away from the support plate.

[0018] With the above structural design, when in use, the electric telescopic rod can be started to move the connecting rod, the connecting rod can move the support plate, the support plate can move the fixed telescopic rod, the fixed telescopic rod can move the electromagnetic suction, and the electromagnetic suction can move the reduction furnace, thus facilitating the disassembly or installation of the reduction furnace and resulting in high working efficiency.

[0019] Furthermore, an extension rod is fixedly provided on the top surface of the support plate, and a support ring is fixedly provided at the end of the extension rod away from the support plate. A fixing rod is fixedly provided on the bottom surface of the support ring, and a hollow sleeve is sleeved on the outside of the fixing rod.

[0020] With the above structural design, when the support plate moves, it will drive the extension rod to move, the extension rod to move, the support ring to move, the support ring to move, the fixed rod to move, and the fixed rod to move the hollow sleeve to be fitted onto the outside of the hexagonal nut.

[0021] Furthermore, a support rod is fixedly provided on the inner surface of the hollow sleeve, and a nut sleeve adapted to a hexagonal nut is fixedly provided at one end of the support rod.

[0022] With the above structural design, the nut sleeve is compatible with the hexagonal nut during use, making it easy to be sleeved on the outside of the hexagonal nut and to abut against the hexagonal nut.

[0023] Furthermore, a fixing plate is fixedly installed at one end of the fixing rod, and a limiting rod is provided on one side of the fixing plate. A vertical groove is opened on the inner surface of the hollow sleeve, and the vertical groove is adapted to the limiting rod.

[0024] With the above structural design, when the hollow sleeve abuts against the bell flange during use, the continuous movement of the fixing rod will push the fixing plate to move directionally along the vertical groove using the limiting rod, so that the nut sleeve can be fitted onto the outside of the hexagonal nut.

[0025] Furthermore, a threaded groove is provided below the vertical groove, and the threaded groove is adapted to the limiting rod.

[0026] With the above structural design, during use, when the limiting rod moves into the threaded groove, the fixed rod continues to descend, which will drive the hollow sleeve to rotate using the threaded groove. The rotation of the hollow sleeve will drive the support rod to rotate, and the rotation of the support rod will drive the nut sleeve to rotate, thereby disassembling the hexagonal nut. This results in high work efficiency. Furthermore, when the nut sleeve and the hexagonal nut are in contact but the contact surfaces do not align, the rotation of the hollow sleeve using the threaded groove will align the contact surfaces of the nut sleeve and the hexagonal nut, making it easier to disassemble the nut, thereby reducing labor and improving work efficiency.

[0027] Furthermore, a buffer spring is fixedly installed on the top surface of the fixed plate, and the end of the buffer spring away from the fixed plate is fixedly connected to the inner top surface of the hollow sleeve.

[0028] The above structural design, utilizing a buffer spring, prevents the fixed rod from causing the hollow sleeve to descend, thus improving the stability of disassembling the hexagonal nut.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the method for quick disassembly and positioning assembly of the reduction furnace;

[0030] The positioning pins, pin sleeve one, and pin sleeve two can accurately position the bell flange and the base flange, which reduces the time spent adjusting the angle and speeds up the installation when installing the bell flange multiple times. Furthermore, the cylinder facilitates the raising or lowering of the bolts, saving a lot of labor and working time, thereby improving the efficiency of disassembling or assembling the reduction furnace.

[0031] When disassembling or installing the bell jar body, the electric telescopic rod is activated to facilitate the movement of the connecting rod, which in turn facilitates the movement of the support plate, which in turn facilitates the movement of the fixed telescopic rod, which in turn facilitates the movement of the electromagnetic suction, which in turn facilitates the movement of the reduction furnace. This makes it easy to disassemble or install the reduction furnace and increases work efficiency.

[0032] When the support plate moves, it will drive the extension rod to move, which in turn will drive the support ring to move. The support ring will then drive the fixed rod to move. As the fixed rod continues to move, when the hollow sleeve comes into contact with the bell flange, the movement of the fixed rod will push the fixed plate to move directionally along the vertical groove using the limit rod, making it easier for the nut sleeve to be fitted onto the outside of the hexagonal nut. At the same time, the continuous descent of the fixed rod will drive the hollow sleeve to rotate using the threaded groove. The rotation of the hollow sleeve will drive the support rod to rotate, which in turn will drive the nut sleeve to rotate, thereby disassembling the hexagonal nut. This process is highly efficient.

[0052] Through the above structural design, the positions of the bell flange 4 and the base flange 9 can be accurately positioned by the positioning pin 11, pin sleeve one 10 and pin sleeve two 12. This reduces the time for adjusting the angle and speeds up the installation when installing the bell flange 4 multiple times. Furthermore, the cylinder 8 facilitates the raising or lowering of the bolt 3, saving a lot of labor and working time, thereby improving the efficiency of disassembling or assembling the reduction furnace.

A buffer spring 1379 is fixedly provided on the top surface of the fixed plate 1377, and the end of the buffer spring 1379 away from the fixed plate 1377 is fixedly connected to the inner top surface of the hollow sleeve 1372.

[0056] Through the above structural design, during use, when the support plate 134 moves, it will drive the extension rod 137 to move. The movement of the extension rod 137 will drive the support ring 1370 to move. The movement of the support ring 1370 will drive the fixed rod 1371 to move. As the fixed rod 1371 continues to move, when the hollow sleeve 1372 abuts against the bell flange 4, the movement of the fixed rod 1371 will push the fixed plate 1377 to move in the direction of the vertical groove 1375 using the limiting rod 1378, so that the nut sleeve 1374 can be fitted onto the outside of the hexagonal nut 6. At the same time, the continuous descent of the fixed rod 1371 will drive the hollow sleeve 1372 to rotate using the threaded groove 1376.
