Description

Technical Field

[0001] This invention relates to the field of single crystal furnace technology, and more particularly to a main heater protection fixture. Background Technology

[0002] A single crystal furnace consists of a tank, a lid, connecting pipes, a heater body, a placement tank, and a support. It is a device used to process single crystal silicon and is quite common in daily life.

[0003] Existing technologies, such as the utility model patent with publication number CN104593863B, disclose a single crystal furnace. This patent employs a furnace body with a furnace cavity; a flow guide tube disposed within the furnace cavity; and a quartz crucible disposed within the furnace cavity and below the flow guide tube. The single crystal furnace also includes an anti-splashing device disposed within the flow guide tube. The anti-splashing device comprises multiple protective components for protecting the ends of the flow guide tube and a driving mechanism. The multiple protective components have recycle positions that are close to each other and protection positions that are far apart from each other. The driving mechanism is drivenly connected to the multiple protective components to drive the multiple protective components to move between the recycle positions and the protection positions. This solves the problem that since the materials of graphite crucibles, graphite resistance heaters, etc., are all carbon, these carbon materials are affected by high-temperature molten silicon, thereby shortening the service life of graphite components and indirectly increasing production costs.

[0004] The inventors discovered a problem during the use of the single crystal furnace: when the heater body heats the placement tank, because the placement tank is made of metal, the heater body is prone to irreversible damage when it comes into contact with the placement tank. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a main heater protection clamp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a main heater protective clamp, comprising a heater body, a protective structure and a fixing structure, wherein a bracket is fixedly connected to the lower surface of the heater body, and a protective structure is provided on the surface of the heater body, the protective structure comprising a protective plate, the protective plate being slidably connected to the heater body, and a connecting strap and a fixing strap being fixedly connected to the upper surface of the protective plate respectively.

[0007] By adopting the above technical solution, when it is necessary to isolate and protect the heater body, the protective plate is installed on the heater body, then the heater body is placed on the single crystal tank, and then the heater body is placed downwards. After being placed in a suitable position, the connecting strap and fixing strap are fixed, and then the heater body is started to heat the single crystal tank. The protective pad can prevent the heater body from contacting the tank and causing unnecessary wear.

[0008] Preferably, the upper ends of the connecting strap and the fixing strap both have an angle of 90 degrees.

[0009] Preferably, the interior of both the connecting strap and the fixing strap is made of glass fiber.

[0010] Preferably, the protective plate has an arc-shaped cross-section, and the protective plate support has a groove with a thickness equal to that of the heater body.

[0011] Preferably, the protective plate is made of silicate material.

[0012] By adopting this preferred solution, the silicate material achieves good heat insulation properties, and its high melting point makes it less likely to be melted by the heater body.

[0013] Preferably, the lower surface of the heater body is provided with a fixing structure, the fixing structure including a main beam, the main beam abutting against the heater body, two extension rods fixedly connected to both ends of the main beam, two slide rails fixedly connected inside the main beam, sliders slidably connected to the inner walls of the slide rails, an arc plate fixedly connected to the upper surface of the sliders, a screw rotatably connected inside the slide rails, the screw rotatably connected to the main beam, a connecting ring rotatably connected to the end of the screw away from the main beam, several auxiliary blocks fixedly connected to the inner wall of the connecting ring, and several locking blocks made of rubber fixedly connected to the arc surface of the screw near the connecting ring.

[0014] This preferred solution achieves the following: when the heater body needs to be fixed, the connecting ring is rotated to move, the connecting ring drives the auxiliary block to move, the auxiliary block drives the locking block to move, the locking block drives the screw to move, and then the screw rotates on the inner wall of the slide rail and the main beam. The screw drives the slider to move, the slider drives the arc plate to move, and then the two arc plates press and fix the tank. When the connecting ring cannot rotate to the moving position, it can be rotated in the opposite direction to reset.

[0015] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one side of the two arc plates that are close to each other.

[0016] By adopting this preferred solution, the anti-slip pad can increase the friction between the arc plate and the heater body, thus preventing the arc plate from sliding when it is pressed and fixed to the heater body.

[0017] Preferably, the arc surface of the connecting ring is fixedly connected to a plurality of fixing rods, and the plurality of fixing rods are evenly distributed on the connecting ring.

[0018] By adopting this preferred solution, the fixing rod can be directly rotated when the connecting ring needs to be rotated, making it more convenient to rotate the connecting ring.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0020] 1. In this invention, by setting a protective structure, the heater body can be easily protected, and irreversible damage can be easily caused to the heater body when it comes into contact with the single crystal tank because the single crystal tank is made of metal.

[0021] 2. In this invention, by setting a fixing structure, the heater body can be easily clamped and fixed, making it convenient to transport and avoiding the difficulty of transporting the heater body due to excessive temperature after use. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, such as Figure 1-5 As shown, the present invention provides a main heater protection clamp, including a heater body 1, a protective structure 3 and a fixing structure 4. A bracket 2 is fixedly connected to the lower surface of the heater body 1, the protective structure 3 is provided on the surface of the heater body 1, and the fixing structure 4 is provided on the lower surface of the heater body 1.

[0031] The specific design and function of its protective structure 3 and fixing structure 4 will be explained below.

[0032] like Figure 1 and Figure 2 As shown, the protective structure 3 includes a protective plate 31, which is slidably connected to the heater body 1. A connecting strap 32 and a fixing strap 33 are fixedly connected to the upper surface of the protective plate 31. Using this technical solution, when the heater body 1 needs to be isolated and protected, the protective plate 31 is installed on the heater body 1, then the heater body 1 is placed on the single crystal tank, and then the heater body 1 is placed downwards. After being placed in the appropriate position, the connecting strap 32 and the fixing strap 33 are fixed. Then, the heater body 1 is started to heat the single crystal tank. The protective pad can prevent unnecessary wear caused by contact between the heater body 1 and the tank. The upper ends of the connecting strap 32 and the fixing strap 33 both have a 90-degree angle. The interior of the connecting strap 32 and the fixing strap 33 is made of glass fiber. The protective plate 31 has an arc-shaped cross-section. The support 2 of the protective plate 31 has a groove with a thickness equal to that of the heater body 1. The protective plate 31 is specifically made of silicate material, which provides good heat insulation and has a high melting point, making it difficult for the heater body 1 to melt.

[0033] The effect of the entire protective structure 3 is that when it is necessary to isolate and protect the heater body 1, the protective plate 31 is installed on the heater body 1, then the heater body 1 is placed on the single crystal tank, then the heater body 1 is placed downwards, and after being placed in the appropriate position, the connecting strap 32 and the fixing strap 33 are fixed, and then the heater body 1 is started to heat. The protective pad can prevent the heater body 1 from causing unnecessary wear. The silicate material has good heat insulation properties, and its high melting point makes it difficult to be melted by the heater body 1.

[0034] like Figure 4 and Figure 5As shown, the fixed structure 4 includes a main beam 402, which abuts against the heater body 1. Two extension rods 401 are fixedly connected to both ends of the main beam 402. Two slide rails 403 are fixedly connected inside the main beam 402. A slider 408 is slidably connected to the inner wall of the slide rail 403. An arc plate 404 is fixedly connected to the upper surface of the slider 408. A screw 409 is rotatably connected inside the slide rail 403. The screw 409 is rotatably connected to the main beam 402. A connecting ring 406 is rotatably connected to the end of the screw 409 away from the main beam 402. Several auxiliary blocks 410 are fixedly connected to the inner wall of the connecting ring 406. Several locking blocks 411 are fixedly connected to the arc surface of the screw 409 near the connecting ring 406. The locking blocks 411 are made of rubber. When it is necessary to fix the heater body 1, the connecting ring 406 is rotated to move it. The connecting ring 406 drives the auxiliary block 410 to move. Then the auxiliary block 410 drives the locking block 411 to move. The locking block 411 drives the screw 409 to move. Then the screw 409 rotates on the inner wall of the slide rail 403 and the main beam 402. The screw 409 drives the slider 408 to move. The slider 408 drives the arc plate 404 to move. Then the two arc plates 404 press and fix the tank. When the connecting ring 406 cannot rotate to the moving position, the connecting ring 406 can be rotated in the opposite direction to reset it. The anti-slip pad 405 is fixedly connected to the side of the two arc plates 404 that are close to each other. The anti-slip pad 405 is a rubber pad. The anti-slip pad 405 can increase the friction between the arc plate 404 and the heater body 1, and prevent the arc plate 404 from sliding when squeezing and fixing the heater body 1. Several fixing rods 407 are fixedly connected to the arc surface of the connecting ring 406. The fixing rods 407 are evenly distributed on the connecting ring 406, so that the fixing rods 407 can be directly rotated when the connecting ring 406 needs to be rotated. The fixing rods 407 make it easier to rotate the connecting ring 406.

[0035] The overall effect of the fixing structure 4 is as follows: when it is necessary to fix the heater body 1, the connecting ring 406 is rotated to move, the connecting ring 406 drives the auxiliary block 410 to move, then the auxiliary block 410 drives the locking block 411 to move, the locking block 411 drives the screw 409 to move, then the screw 409 rotates on the inner wall of the slide rail 403 and the main beam 402, the screw 409 drives the slider 408 to move, the slider 408 drives the arc plate 404 to move, and then the two arc plates 404 press and fix the tank. When the connecting ring 406 cannot rotate to the moving position, the connecting ring 406 can be rotated in the opposite direction to reset. The anti-slip pad 405 can increase the friction between the arc plate 404 and the tank, and prevent the arc plate from sliding when pressing and fixing the tank. When it is necessary to rotate the connecting ring 406, the fixing rod 407 can be rotated directly, and the fixing rod 407 makes it easier to rotate the connecting ring 406.

[0036] The overall working principle is as follows: when it is necessary to isolate and protect the heater body 1, the protective plate 31 is installed on the heater body 1, then the heater body 1 is placed on the single crystal tank, and then the heater body 1 is placed downwards. After it is placed in the appropriate position, the connecting strap 32 and the fixing strap 33 are fixed, and then the heater body 1 is started to heat. The protective pad can prevent the heater body 1 from being damaged by unnecessary wear. The silicate material has good heat insulation properties, and its melting point is high and it is not easy to be melted by the heater body 1.

[0037] When it is necessary to fix the heater body 1, the connecting ring 406 is rotated to move it. The connecting ring 406 drives the auxiliary block 410 to move, and then the auxiliary block 410 drives the locking block 411 to move. The locking block 411 drives the screw 409 to move, and then the screw 409 rotates on the inner wall of the slide rail 403 and the main beam 402. The screw 409 drives the slider 408 to move, and the slider 408 drives the arc plate 404 to move. Then the two arc plates 404 press and fix the tank. When the connecting ring 406 cannot rotate to the moving position, the connecting ring 406 can be rotated in the opposite direction to reset it. The anti-slip pad 405 can increase the friction between the arc plate 404 and the tank to prevent the arc plate from sliding when pressing and fixing the tank. When it is necessary to rotate the connecting ring 406, the fixing rod 407 can be rotated directly. The fixing rod 407 makes it easier to rotate the connecting ring 406.
