Description

Technical Field

[0001] This utility model relates to the field of novel water-cooled screens, and more particularly to a novel water-cooled screen. Background Technology

[0002] The water-cooled screen of the single crystal furnace is a key component used for cooling during the growth of single crystal silicon. It is usually installed inside the single crystal furnace to control the temperature distribution inside the furnace and ensure that the single crystal silicon can maintain a uniform temperature gradient during the growth process, thereby improving the quality of the crystal.

[0003] Existing technologies, such as the utility model patent with publication number CN219059199U, disclose a novel water-cooled screen for a Czochralski single crystal furnace. This patent uses a water-cooled screen body with an auxiliary high-efficiency cooling structure fixedly connected to its outer side. The inner side of the water-cooled screen body has a high-efficiency heat dissipation curved surface. This curved surface allows the device to pass through a larger heat dissipation area, improving heat dissipation efficiency and removing more latent heat of crystallization. The auxiliary high-efficiency cooling structure includes a heat-conducting ring, a temperature-conducting output plate, a sheet-like temperature-conducting plate, and an inner temperature-conducting conduit. This utility model, through the design of a high-efficiency heat dissipation curved surface inside the water-cooled screen, allows the device to pass through a larger heat dissipation area, improving heat dissipation efficiency and removing more latent heat of crystallization. Furthermore, the design of the auxiliary high-efficiency cooling structure facilitates efficient and rapid auxiliary heat dissipation of the water-cooled screen, thereby further enabling the rapid removal of accumulated temperature from the water-cooled screen.

[0004] The inventors discovered in daily use that existing technologies may cause the frame and water-cooled screen to stick together during heating or operation, making them difficult to remove after lifting. During heating or cooling, temperature changes in the coolant inside the water-cooled screen may cause expansion or contraction, increasing the difficulty of disassembly. Over long-term use, the coolant may form corrosion or deposits, leading to a tight bond between the frame and the water-cooled screen, requiring more force to disassemble. The frame design may not have considered ease of disassembly, resulting in the need for additional tools or steps to remove the frame. If operators do not follow the standard procedures during disassembly, improper force or incorrect disassembly methods may make the frame difficult to remove.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies.

[0007] To solve the above technical problems, this utility model provides a novel water-cooled screen, comprising: a water-cooled screen body, a connecting frame installed at the upper end of the water-cooled screen body, a plurality of cooling towers installed on the arc surface of the connecting frame, an auxiliary structure provided on the surface of the water-cooled screen body, the auxiliary structure including a fixing frame disposed around the water-cooled screen, a rotating shaft rotatably connected to the inner wall of the fixing frame, a connecting block fixedly connected to the arc surface of the rotating shaft, an auxiliary frame fixedly connected to the end of the connecting block away from the fixing frame, and an auxiliary frame fixedly connected to the end of the auxiliary frame away from the connecting block. The device includes a connecting block. A rod is slidably connected to the inner wall of the fixed frame at the end away from the rotating shaft. The rod engages with the connecting block. A washer is fixedly connected to the upper end of the rod. A spring is fitted onto the arc surface of the rod. The two ends of the spring are fixedly connected to the washer and the fixed frame, respectively. Two connecting rods are fixedly connected to the auxiliary frame and the fixed frame on opposite sides. A fixed ring is fixedly connected to the arc surface of the connecting rod. A round rod is fixedly connected to the side of the two fixed rings that are close to each other. A rotating ring is rotatably connected to the arc surface of the round rod. A handle is fixedly connected to the arc surface of the rotating ring.

[0008] The aforementioned components achieve the following effects: When the water-cooled screen body needs to be lifted, the connecting rod is pulled to move it. The connecting rod drives the fixed frame and the auxiliary frame to move. Then, the auxiliary frame is fitted onto the fixed frame and connected to it. The auxiliary frame drives the connecting block to move. The auxiliary block drives the rotating shaft to rotate on the inner wall of the fixed frame. The auxiliary frame drives the connecting block to move. Then, the connecting block pushes the sliding rod to move. The sliding rod drives the shim to move. The shim drives the spring to stretch. After moving to the appropriate position, the spring contracts, causing the insertion rod to be inserted into the connecting block for fixation. When the pulling method needs to be adjusted, the handle is pulled to move it. The handle drives the rotating ring to move. The rotating ring drives the round rod to move. The round rod drives the fixed ring to move. The fixed rod drives the connecting rod to move.

[0009] Preferably, an anti-slip sleeve is fixedly connected to the arc surface of the handle, and the cross-section of the anti-slip sleeve is annular.

[0010] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the hand and the handle, preventing slippage when pulling the handle.

[0011] Preferably, both the inner walls of the fixed frame and the auxiliary frame are fixedly connected with anti-slip pads, which are rubber pads.

[0012] The effect achieved by the above components is that the anti-slip pad can increase the friction between the fixed frame and the auxiliary frame, preventing the fixed frame and the auxiliary frame from sliding when they come into contact with and are lifted by the water-cooled screen body.

[0013] Preferably, both ends of the rotating shaft are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the connecting block and the fixing frame, respectively.

[0014] The effect achieved by the above components is that when the fixed frame and the auxiliary frame are separated, the connecting block drives the coil spring to retract, and then the rebound force of the coil spring drives the fixed frame and the auxiliary frame to reset.

[0015] Preferably, the cross-section of the insertion rod is circular, and the insertion rod is a stainless steel rod.

[0016] The effect achieved by the above components is that the insert rod can limit the spring, preventing the spring from deforming during use and improving the service life of the spring.

[0017] Preferably, the connecting rod has a circular cross-section and is made of titanium alloy.

[0018] The effect achieved by the above components is that the titanium alloy material is relatively hard, which can prevent the connecting rod from being damaged during use.

[0019] Preferably, the arc surface of the gasket is fixedly connected to a plurality of pull plates, and the cross-section of the pull plates is in the shape of a straight groove.

[0020] The effect achieved by the above components is that when it is necessary to pull the pad and the insert rod, the handle can be pulled directly to move them, making it easier to move the insert rod and the pad.

[0021] Compared with related technologies, the novel water-cooled screen provided by this utility model has the following beneficial effects:

[0022] This invention provides a novel water-cooled screen. By incorporating an auxiliary structure, existing technologies can prevent the frame from sticking to the water-cooled screen during heating or operation, making it difficult to remove after lifting. During heating or cooling, temperature changes in the coolant inside the screen can cause expansion or contraction, increasing the difficulty of disassembly. Over time, the coolant may form corrosion or deposits, leading to a tight bond between the frame and the screen, requiring greater force for disassembly. The frame design may not have considered ease of disassembly, necessitating additional tools or steps. Furthermore, improper disassembly by operators, such as incorrect force or methods, can make the frame difficult to remove. This device allows the water-cooled screen to be removed before heating after the frame is lifted, preventing the frame from being heated and allowing for easy adjustment of the lifting method.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6 The present invention provides a novel water-cooled screen, comprising: a water-cooled screen body 1, a connecting frame 2 installed on the upper end of the water-cooled screen body 1, a plurality of cooling towers 3 installed on the arc surface of the connecting frame 2, and an auxiliary structure 4 provided on the surface of the water-cooled screen body 1.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 6The auxiliary structure 4 includes a fixed frame 402, which is disposed around the water-cooled screen. A rotating shaft 411 is rotatably connected to the inner wall of the fixed frame 402. A connecting block 409 is fixedly connected to the arc surface of the rotating shaft 411. An auxiliary frame 401 is fixedly connected to the end of the connecting block 409 away from the fixed frame 402. A connecting block 413 is fixedly connected to the end of the auxiliary frame 401 away from the connecting block 409. A plug rod 414 is slidably connected to the inner wall of the end of the fixed frame 402 away from the rotating shaft 411. The plug rod 414 engages with the connecting block 413. A washer 416 is fixedly connected to the upper end. A spring 415 is fitted on the arc surface of the insertion rod 414. The two ends of the spring 415 are fixedly connected to the washer 416 and the fixed frame 402 respectively. Two connecting rods 403 are fixedly connected to the side of the auxiliary frame 401 and the fixed frame 402 that are far apart from each other. A fixing ring 404 is fixedly connected to the arc surface of the connecting rod 403. A round rod 405 is fixedly connected to the side of the two fixing rings 404 that are close to each other. A rotating ring 406 is rotatably connected to the arc surface of the round rod 405. A handle 407 is fixedly connected to the arc surface of the rotating ring 406. When it is necessary to lift the water-cooled screen body 1, pull the connecting rod 403 to move it. The connecting rod 403 drives the fixed frame 402 and the auxiliary frame 401 to move. Then, the auxiliary frame 401 is fitted onto the fixed frame 402, and then the auxiliary frame 401 is connected to the fixed frame 402. The auxiliary frame 401 drives the connecting block 409 to move. The auxiliary block drives the rotating shaft 411 to rotate on the inner wall of the fixed frame 402. The auxiliary frame 401 drives the connecting block 413 to move. Then, the connecting block 413 pushes the sliding rod to move. The sliding rod drives the pad 416 to move. When the handle moves, the pad 416 stretches the spring 415. After moving to the appropriate position, the spring 415 retracts, causing the insert rod 414 to insert into the connecting block 413 for fixation. When the pulling method needs to be adjusted, the handle 407 is pulled, which in turn moves the rotating ring 406. The rotating ring 406 moves the round rod 405, which in turn moves the fixing ring 404. The fixing rod then moves the connecting rod 403. An anti-slip sleeve 408 is fixedly connected to the arc surface of the handle 407. The anti-slip sleeve 408 has a circular cross-section. The anti-slip sleeve 408 increases the friction between the hand and the handle 407, preventing slippage when pulling the handle. Anti-slip pads 412, which are rubber pads, are fixedly connected to the inner walls of both the fixed frame 402 and the auxiliary frame 401. The anti-slip pad 412 can increase the friction between the fixed frame 402 and the auxiliary frame 401, and prevent the fixed frame 402 and the auxiliary frame 401 from sliding when they come into contact with the water-cooled screen body 1 and are lifted. The arc surfaces at both ends of the rotating shaft 411 are fitted with coil springs 410, and the two ends of the coil springs 410 are fixedly connected to the connecting block 409 and the fixed frame 402 respectively.When the fixed frame 402 separates from the auxiliary frame 401, the connecting block 409 drives the coil spring 410 to retract. Then, the rebound force of the coil spring 410 drives the fixed frame 402 and the auxiliary frame 401 to reset. The cross-section of the insertion rod 414 is circular, and the insertion rod 414 is a stainless steel rod. The insertion rod 414 can limit the spring 415, preventing the spring 415 from deforming during use and improving the service life of the spring 415. The cross-section of the connecting rod 403 is circular, and the connecting rod 403 is a titanium alloy rod. The titanium alloy material is relatively hard, which can prevent the connecting rod 403 from being damaged during use. Several pull plates 417 are fixedly connected to the arc surface of the gasket 416. The cross-section of the pull plate 417 is straight groove-shaped. When it is necessary to pull the gasket 416 and the insertion rod 414, the handle 407 can be pulled directly to move them. The handle 407 makes it easier to move the insertion rod 414 and the gasket 416.

[0034] The working principle of this novel water-cooled screen is as follows: When the water-cooled screen body 1 needs to be lifted, the connecting rod 403 is pulled to move it. The connecting rod 403 drives the fixed frame 402 and the auxiliary frame 401 to move. Then, the auxiliary frame 401 is fitted onto the fixed frame 402, and then the auxiliary frame 401 is connected to the fixed frame 402. The auxiliary frame 401 drives the connecting block 409 to move, and the auxiliary block drives the rotating shaft 411 to rotate on the inner wall of the fixed frame 402. 01 drives the connecting block 413 to move, then the connecting block 413 pushes the slide rod to move, the slide rod drives the washer 416 to move, the washer 416 drives the spring 415 to stretch, after moving to the appropriate position, the spring 415 retracts and drives the insertion rod 414 to insert into the connecting block 413 for fixation. When it is necessary to adjust the pulling method, pull the handle 407 to move, the handle 407 drives the rotating ring 406 to move, the rotating ring 406 drives the round rod 405 to move, the round rod 405 drives the fixed rod 405 to move. The fixed ring 404 moves, and the fixed rod drives the connecting rod 403 to move. The anti-slip sleeve 408 increases the friction between the hand and the handle 407, preventing slippage when pulling the handle. The anti-slip pad 412 increases the friction between the fixed frame 402 and the auxiliary frame 401, preventing slippage when the fixed frame 402 and the auxiliary frame 401 come into contact with and are lifted from the water-cooled screen body 1. When the fixed frame 402 and the auxiliary frame 401 separate, the connecting block 409 drives the coil spring 410 to retract. The rebound force of the coil spring 410 drives the fixed frame 402 and the auxiliary frame 401 to reset. The insertion rod 414 can limit the spring 415 to prevent the spring 415 from deforming during use, thus improving the service life of the spring 415. The titanium alloy material is relatively hard, which can prevent the connecting rod 403 from being damaged during use. When it is necessary to pull the pad 416 and the insertion rod 414, the handle 407 can be pulled directly to move them. The handle 407 makes it easier to move the insertion rod 414 and the pad 416.
