[0002] Single crystal furnaces, widely used in semiconductor manufacturing and crystal growth processes, employ filter tanks to remove impurities and ensure crystal quality. Traditionally, single crystal furnace filter tanks are water-cooled to maintain a stable operating temperature and prevent overheating. However, in practice, the cooling water in the filter tank may heat up over time, reducing its cooling effect and impacting normal operation and filtration. Furthermore, traditional filter screens often require disassembly of the filter tank for maintenance and cleaning, a complex and time-consuming process that is difficult to ensure sealing, potentially affecting equipment efficiency. Therefore, improving cooling efficiency and simplifying the cleaning and replacement process of filter screens has become a key technological challenge. Utility Model Content

Detailed Implementation
[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3 This utility model provides an embodiment of a novel single-crystal furnace filter tank, comprising a tank body 1, a cooling sleeve 2 fixedly connected to the outer side of the tank body 1, a water storage tank 6 fixedly connected to the middle of the outer side of the cooling sleeve 2, semiconductor coolers 7 fixedly connected to both the front and rear sides of the water storage tank 6, sealing gaskets 3 fixedly connected to both the upper and lower sides of the cooling sleeve 2, mounting blocks 4 evenly fixedly connected around the lower outer side of the cooling sleeve 2, support legs 5 fixedly connected to the lower part of the mounting blocks 4, a discharge pipe 19 fixedly connected to the lower middle of the tank body 1, a valve 20 fixedly connected to the outer side of the discharge pipe 19, and a valve 20 fixedly connected to the upper right side of the cooling sleeve 2. A circulation assembly is provided for recycling cooling water. The circulation assembly includes a support plate 8, which is fixedly connected to the upper right side of the cooling sleeve 2. A water pump 9 is fixedly connected to the upper wall of the support plate 8. A water pump 10 is fixedly connected to the input end of the water pump 9, and a water delivery pipe 11 is fixedly connected to the output end of the water pump 9. A water guide pipe 12 is fixedly connected to the rear side of the cooling sleeve 2. The end of the water guide pipe 12 away from the cooling sleeve 2 is fixedly connected to the water storage tank 6. The end of the water pump 10 away from the water pump 9 is fixedly connected to the water storage tank 6. The end of the water delivery pipe 11 away from the water pump 9 is fixedly connected to the cooling sleeve 2.
[0027] By controlling the start of the semiconductor cooler 7, the cooling water inside the water storage tank 6 is cooled down, ensuring effective control of the cooling water temperature. Subsequently, by starting the water pump 9, the water pump 9 drives the water extraction pipe 10 to extract the cooling water from the water storage tank 6. The water pump 9 delivers this cooling water to the cooling jacket 2 through the water delivery pipe 11. In the jacket, the cooling water exchanges heat with the tank body 1, absorbing the heat generated by the tank body 1, thereby achieving a cooling effect. Finally, the water after heat exchange is discharged through the water guide pipe 12 and returned to the water storage tank 6 for cooling circulation. The whole process effectively realizes the circulating cooling system of the single crystal furnace filter tank, which not only improves the cooling efficiency of the equipment, but also enhances its stability and practicality under long-term operation. This allows the single crystal furnace filter tank to maintain a low operating temperature under high load conditions, extending the service life of the equipment and improving the overall working performance.
[0028] A mounting bracket 18 is evenly and slidably connected around the inner wall of the tank body 1. A filter screen 17 is fixedly connected to the opposite side of the mounting bracket 18. A quick-release assembly is provided on the upper part of the tank body 1 for quick disassembly of the filter screen 17. The quick-release assembly includes a limiting sleeve 13, which is fixedly connected to the upper part of the front and rear sides of the tank body 1. A limiting block 14 is slidably connected inside the limiting sleeve 13. A cover plate 15 is fixedly connected to the opposite side of the limiting block 14. A handle 16 is fixedly connected to the upper part of the cover plate 15.
[0029] By turning the handle 16, the handle 16 drives the cover plate 15 to rotate. The cover plate 15 is connected to the limiting block 14. During the rotation, the limiting block 14 disengages from the limiting sleeve 13, ensuring that the firm connection between the cover plate 15 and the tank body 1 can be smoothly released. Then, the operator continues to pull the handle 16 to drive the cover plate 15 away from the tank body 1, opening the top of the tank body 1 and providing convenient access space for subsequent maintenance operations. Finally, the mounting bracket 18 is pulled, and the mounting bracket 18 lifts and removes the filter screen 17 from the tank body 1. Through this simple disassembly process, not only can the filter screen 17 be quickly disassembled, but the labor intensity and operation difficulty of cleaning the filter screen 17 are also greatly reduced. This design greatly improves the maintenance efficiency of the single crystal furnace filter tank and ensures the long-term stable operation of the equipment.
[0030] Working principle: When cooling of the single crystal furnace filter tank is required, the semiconductor cooler 7 is activated to cool the cooling water inside the water storage tank 6. Then, the water pump 9 is activated to drive the water pumping pipe 10 to pump the cooling water from the water storage tank 6 into the water pump 9. The cooling water is then fed into the cooling jacket 2 through the water delivery pipe 11. The cooling water in the cooling jacket 2 exchanges heat with the tank body 1. Finally, the water is discharged into the water storage tank 6 through the water guide pipe 12 for further cooling. This achieves the cooling of the single crystal furnace filter tank. The circulating cooling system improves the practicality of the single crystal furnace filter tank. When the filter screen 17 needs to be disassembled, the handle 16 is turned to rotate the cover plate 15. The cover plate 15 rotates the limiting block 14 to disengage from the limiting sleeve 13. Then, the handle 16 is pulled to disengage the cover plate 15 from the tank body 1. Finally, the mounting bracket 18 is pulled to disengage the filter screen 17 from the tank body 1. This allows for quick disassembly of the filter screen 17 in the single crystal furnace filter tank, reducing the difficulty of cleaning the filter screen 17.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
