Description

Technical Field

[0001] This utility model relates to the technical field of angle deflection devices, specifically a manual angle deflection device for electrode spraying in a polycrystalline silicon reduction furnace. Background Technology

[0002] The polycrystalline silicon reduction furnace is a core piece of equipment in the upstream of the photovoltaic and semiconductor industry chain. It is responsible for reducing fumed silicon (mainly trichlorosilane SiHCl3) with hydrogen (H2) at high temperatures to produce high-purity polycrystalline silicon rods. The electrodes are the core components of the polycrystalline silicon reduction furnace, requiring a coating to be sprayed onto their outer surface for protection. During electrode coating, a positioning structure is needed to fix the electrodes in place, facilitating the coating process.

[0003] Regarding the above technical conditions, there is still a drawback: spraying requires multiple angles of the electrode during the spraying process, but the positioning structure can generally only position the electrode and cannot change the angle of the electrode according to the spraying requirements.

[0004] Based on this, this utility model designs a manual angle deflection device for electrode spraying in a polycrystalline silicon reduction furnace to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a manual angle deflection device for electrode spraying in a polycrystalline silicon reduction furnace, so as to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manual angle deflection device for electrode spraying in a polycrystalline silicon reduction furnace, comprising a positioning structure, wherein the positioning structure is connected to a deflection structure, the deflection structure comprising a base, a gear, a rotating rod, and a semicircular plate, wherein the positioning structure is provided with a rotating shaft, the rotating shaft being rotatably connected to the base, the semicircular plate being fixedly mounted on the rotating shaft, wherein multiple toothed grooves are formed on the outer side wall of the semicircular plate, the gear being mounted on the base and meshing with the toothed grooves, a reducer being fixedly mounted on the base, a fixing hole being formed on the base, one output shaft of the reducer passing through the fixing hole and being fixedly connected to the gear, the rotating rod being fixedly connected to the other output shaft of the reducer, a first limiting rod being fixedly connected to the base, a limiting plate being fixedly mounted on the semicircular plate, and the first limiting rod being below the limiting plate.

[0007] Preferably, the positioning structure includes a mounting base, grippers, a fastening assembly, a chuck, and a drive assembly. The rotating shaft is fixedly mounted on the mounting base, the chuck is mounted on the mounting base, the grippers are mounted on the chuck, and multiple grippers are mounted on the chuck. The drive assembly is mounted on the mounting base and connected to the chuck. The fastening assembly is mounted on the chuck and connected to the grippers.

[0008] Preferably, an auxiliary ring is fixedly connected to the rotating rod, and an auxiliary rod is fixedly connected to the auxiliary ring.

[0009] Preferably, a second limiting rod is fixedly connected to the base.

[0010] Preferably, a stabilizing rod is fixedly mounted on the base, and two stabilizing rods are mirror-arranged on the base.

[0011] Preferably, the bottom of the base is made of solid metal material, and the thickness of the bottom of the base is greater than 5cm.

[0012] In summary, this application has the following beneficial technical effects: During use, the electrode is positioned and fixed using the positioning structure. By holding and rotating the auxiliary rod, the rotating rod's rotational power is transmitted to the gears via a reducer. The gears rotate, driving the semi-circular plate to rotate. The semi-circular plate then rotates the positioning structure, causing a change in the angle between the positioning structure and the base. When the gear rotates counterclockwise, the angle between the positioning structure and the first limiting rod decreases. When the limiting plate abuts against the first limiting rod, the rotation angle of the positioning structure on that side is at its maximum. When the gear rotates clockwise, the angle between the positioning structure and the second limiting rod decreases. When the drive assembly abuts against the second limiting rod, the rotation angle of the positioning structure on that side is at its maximum. By changing the angle of the positioning structure, the electrode can be sprayed from multiple angles, improving the coating effect and achieving the effect of changing the electrode angle according to usage requirements.

Detailed Implementation

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0018] A manual angle deflection device for electrode spraying in a polycrystalline silicon reduction furnace includes a positioning structure connected to a deflection structure. The deflection structure includes a base 5, a gear 17, a rotating rod 8, and a semi-circular plate 12. The positioning structure has a rotating shaft rotatably connected to the base 5. The semi-circular plate 12 is fixedly mounted on the rotating shaft, and multiple toothed grooves 11 are formed on the outer side wall of the semi-circular plate 12. The gear 17 is mounted on the base 5 and meshes with the toothed grooves 11.

[0019] A reducer 9 is fixedly mounted on the base 5. A fixing hole is provided on the base 5. One output shaft of the reducer 9 passes through the fixing hole and is fixedly connected to the gear 17. The rotating rod 8 is fixedly connected to the other output shaft of the reducer 9. The reducer 9 is a closed mechanical transmission device used to convert the high-speed, low-torque output of a motor or engine into a low-speed, high-torque output to match the needs of the working machine.

[0020] In this embodiment, an external force is applied to the rotating rod 8 by hand, and the rotating rod 8 is rotated under the action of the external force. The power of the rotating rod 8 can be transmitted to the gear 17 through the reducer 9, so that the gear 17 rotates. The gear 17 then drives the semicircular plate 12 to rotate. After the semicircular plate 12 rotates, it carries the positioning structure to rotate, and the angle between the positioning structure and the base 5 changes.

[0021] A first limiting rod 16 is fixedly connected to the base 5. The first limiting rod 16 is located on the side of the base 5 away from the rotating rod 8. A limiting plate 13 is fixedly installed on the end of the semicircular plate 12 away from the rotating rod 8, and the first limiting rod 16 is below the limiting plate 13. The first limiting rod 16 and the limiting plate 13 limit the rotation angle of the positioning structure, making it difficult for the gear 17 to derail from the semicircular plate 12. When the limiting plate 13 abuts against the first limiting rod 16, the positioning structure is rotated to its maximum angle on that side.

[0022] The positioning structure includes a mounting base 14, grippers 1, a fastening assembly 15, a chuck 2, and a drive assembly 3. The rotating shaft is fixedly mounted on the mounting base 14, the chuck 2 is mounted on the mounting base 14, and the grippers 1 are mounted on the chuck 2. The grippers 1 and chuck 2 are movable relative to each other, and multiple grippers 1 are provided on the chuck 2. The drive assembly 3 is mounted on the mounting base 14 and connected to the chuck 2. The fastening assembly 15 is mounted on the chuck 2 and connected to the grippers 1.

[0023] When positioning the electrode, place the electrode on the chuck 2, positioning it between multiple jaws 1. Move the jaws 1 until they press against the electrode, and then secure them to the chuck 2 using the fastening assembly 15. At this point, the electrode is also fixed to the chuck 2. Activate the drive assembly 3, which causes the chuck 2 to rotate. The electrode rotates along with the chuck 2, facilitating the application of the coating to the electrode.

[0024] An auxiliary ring 7 is fixedly connected to the rotating rod 8, and an auxiliary rod 6 is fixedly connected to the auxiliary ring 7. The rotating rod 8 can be rotated via the auxiliary ring 7, and the auxiliary rod 6 can also be rotated via the auxiliary rod 6. A second limiting rod 4 is fixedly connected to the base 5. The second limiting rod 4 is located on the side of the base 5 away from the first limiting rod 16, and is below the drive assembly 3. The second limiting rod 4 limits the rotation angle of the positioning structure on that side, preventing the gear 17 from derailing from the semicircular plate 12. When the drive assembly 3 abuts against the second limiting rod 4, the rotation angle of the positioning structure on that side is at its maximum.

[0025] A stabilizing rod 10 is fixedly mounted on the base 5. The stabilizing rod 10 is fixedly mounted on the side of the base 5 where the first limiting rod 16 is located. Two stabilizing rods 10 are mirror-image mounted on the base 5. The stabilizing rod 10 increases the contact area between the deflection structure and the ground, thereby improving the stability of the deflection structure in contact with the ground. The bottom of the base 5 is made of solid metal material, and the thickness of the bottom of the base 5 is greater than 5cm, which increases the center of gravity of the base 5 and further improves the stability of the deflection structure.

[0026] The implementation principle of this embodiment is as follows: In use, the electrode is positioned and fixed using the positioning structure. The auxiliary rod 6 is held and rotated by hand, causing the rotating rod 8 to rotate. The rotational power of the rotating rod 8 is transmitted to the gear 17 via the reducer 9. The gear 17 rotates, driving the semi-circular plate 12 to rotate. The semi-circular plate 12 rotates, carrying the positioning structure with it, thus changing the angle between the positioning structure and the base 5. When the gear 17 rotates counterclockwise, the angle between the positioning structure and the first limiting rod 16 decreases. When the limiting plate 13 abuts against the first limiting rod 16, the rotation angle of the positioning structure on that side is at its maximum. When the gear 17 rotates clockwise, the angle between the positioning structure and the second limiting rod 4 decreases. When the driving component 3 abuts against the second limiting rod 4, the rotation angle of the positioning structure on that side is at its maximum. By changing the angle of the positioning structure, the electrode can be sprayed from multiple angles, improving the coating effect and achieving the effect of changing the electrode angle according to usage requirements.
