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.

[0024] like Figures 1 to 3 As shown, the present invention provides a drying device for monocrystalline silicon rods used in the production of new energy batteries, comprising a drying device body 1 and a conveying device 2. The conveying device 2 is installed on one side of the drying device body 1. A uniform drying component 3 is provided on the side of the drying device body 1 near the conveying device 2. A heat insulation component 4 is installed on the side of the drying device body 1 near the conveying device 2.

[0025] refer to Figure 2 The uniform drying component 3 includes heating blocks 31, and several heating blocks 31 are arranged at equal distances. A concentrated hopper 32 is arranged on the outside of the heating blocks 31. The concentrated hopper 32 is installed on one side of the drying device body 1. A connecting pipe 33 is connected to the top of the concentrated hopper 32. A hot air blower 34 is connected to the other end of the connecting pipe 33. The hot air blower 34 is installed on the top of the drying device body 1.

[0026] As a technical optimization of this utility model, by setting up a uniform drying component 3 and starting the hot air blower 34, the blower draws in air and heats it at its suction end, and then sends the hot air into the connecting pipe 33 and the concentrated hopper 32 through its output end. The user starts the heating block 31 to further increase the heat of the hot air and stably dry the material. This can quickly increase the temperature of the surface and inside of the monocrystalline silicon rod and accelerate the evaporation of moisture. Compared with the traditional drying method, it greatly shortens the drying time and improves the uniformity of drying the material.

[0027] refer to Figure 2 The heat insulation component 4 includes a heat insulation box 41, which is located on top of the conveying device 2. The top of the heat insulation box 41 is connected to the bottom of the collection hopper 32. A vacuum heat insulation plate 42 is installed on the outside of the heat insulation box 41. A collection box 43 is installed at the bottom inside the conveying device 2. A blower 44 is connected to the bottom of the collection box 43. A circulation pipe 45 is connected to the output end of the blower 44. The other end of the circulation pipe 45 is connected to one side of the connecting pipe 33. One side of the collection box 43 is installed on the drying device body 1.

[0028] As a technical optimization of this utility model, by setting up a heat insulation component, the heat insulation box 41 plays a good role in heat preservation of the bottom of the concentrated hopper 32, slowing down the heat dissipation rate of the hot air, so that the hot air can act more effectively on the monocrystalline silicon rod. The setting of the vacuum heat insulation plate 42 greatly reduces the heat loss of the heat insulation box 41 and reduces energy consumption. By starting the blower 44, the hot air can be recovered and transported back to the connecting pipe 33 through the circulation pipe 45, realizing the recycling of heat and further improving the energy utilization rate.

[0029] refer to Figure 3 A connecting rod 5 is installed on the top of the heating block 31, and the outer side of the connecting rod 5 is installed inside the concentrator 32.

[0030] As a technical optimization of this utility model, by setting a connecting rod 5, the connecting rod 5 can drive the heating block 31 to be installed inside the centralized hopper 32. At the same time, the uniform installation can make the output hot air more uniform, and will not affect the flow of hot air.

[0031] refer to Figure 2 The intake end of the hot air blower 34 is connected to a ventilation pipe 6, and a filter plate 7 is installed at the other end of the ventilation pipe 6.

[0032] As a technical optimization of this utility model, by setting up a ventilation pipe 6 and a filter plate 7, the ventilation pipe 6 provides a stable airflow to the hot air blower 34, ensuring that the hot air blower 34 can work continuously and normally. The filter plate 7 effectively blocks dust and impurities from entering the interior of the hot air blower 34, preventing these impurities from causing wear or blockage to the fan blades, motor and other components of the hot air blower 34, extending the service life of the hot air blower 34, improving the reliability of equipment operation, and reducing the cost of equipment maintenance and replacement of parts.

[0033] refer to Figure 3 A guide plate 8 is installed on the top of the inner wall of the centralized bucket 32. Several guide plates 8 are provided and are arranged at equal intervals.

[0034] As a technical optimization of this utility model, by setting up air guide plates 8, the air guide plates 8 are evenly arranged at the top of the inner wall of the concentrated bucket 32, which can reasonably guide the hot air, so that the air force is delivered to the top of the conveying device 2 more evenly, further enhancing the uniformity of the single crystal silicon rod drying process, ensuring that all parts of the single crystal silicon rod can fully receive the hot air, and avoiding the phenomenon of local over-drying or under-drying.

[0035] refer to Figure 3 A fixing rod 9 is installed on one side of the inner wall of the heat preservation box 41, and a temperature sensor 10 is installed on the other end of the fixing rod 9. The temperature sensor 10 is electrically connected to a temperature display 11 through a wire, and the temperature display 11 is installed on the front of the vacuum insulation plate 42.

[0036] As a technical optimization of this utility model, by setting a fixing rod 9, a temperature sensor 10 and a temperature display 11, the fixing rod 9 installed on one side of the inner wall of the heat preservation box 41 fixes the temperature sensor 10. The temperature sensor 10 detects the internal temperature of the heat preservation box 41 in real time and sends the detected temperature data to the temperature display 11, so that the user can intuitively and timely understand the internal temperature changes. The temperature controller 12 is electrically connected to the heating block 31 and the temperature display 11, and the user can flexibly adjust the temperature of the heating block 31 according to actual needs through the temperature controller 12.

[0037] refer to Figure 3 A temperature controller 12 is installed on the front of the vacuum insulation plate 42. The temperature controller 12 is electrically connected to the heating block 31 through wires and to the temperature display 11 through wires.

[0038] As a technical optimization of this utility model, by setting a temperature controller 12, the temperature controller 12 can control the temperature of the heating block 31 during use, thereby enhancing the convenience of temperature control during use.

[0039] The working principle and usage process of this utility model are as follows: First, place the monocrystalline silicon rod on the conveying device 2, connect the power supply and start the equipment. The hot air blower 34 starts working. Outside air enters through the ventilation pipe 6. The filter plate 7 on the ventilation pipe 6 blocks dust and impurities, preventing them from entering the hot air blower 34 and affecting its operation. The hot air blower 34 heats the air, and the hot air enters the centralized hopper 32 through the connecting pipe 33. According to the production process requirements, the temperature controller 12 is operated to turn on the heating blocks 31. Multiple equally spaced heating blocks 31 heat up, further increasing the temperature of the hot air in the centralized hopper 32, which is then evenly blown onto the monocrystalline silicon rod for drying. The air guide plate 8 inside the centralized hopper 32 directs the hot air... The airflow is guided in a reasonable manner to ensure that all parts of the monocrystalline silicon rod are heated evenly. The heat preservation box 41 is located at the top of the conveying device 2 and is connected to the bottom of the collection hopper 32. It can keep the bottom of the collection hopper 32 warm, slow down the heat loss of hot air, and allow the hot air to dry the monocrystalline silicon rod more effectively, achieving a uniform drying effect. The vacuum insulation plate 42 outside the heat preservation box 41 reduces heat loss and lowers energy consumption. After the equipment has been running for a period of time, the blower 44 is started. It draws in hot air from the bottom of the collection box 43, which is then sent back to the connecting pipe 33 through the circulation pipe 45 and mixed with the hot air output from the hot air blower 34 to achieve heat recycling and improve energy utilization.

[0040] Inside the insulation box 41, the temperature sensor 10 on the fixing rod 9 monitors the temperature in real time and transmits the data to the temperature display 11 on the front of the vacuum insulation plate 42. If the temperature does not meet the drying process requirements, the temperature of the heating block 31 can be adjusted by the temperature controller 12. The temperature is increased when it is low and decreased when it is high, so as to accurately control the temperature, ensure the drying effect, avoid damage to the monocrystalline silicon rod due to abnormal temperature, and enhance the use effect of the monocrystalline silicon rod drying device.

[0041] In summary, this new energy battery production monocrystalline silicon rod drying device, by setting up a uniform drying component 3 in conjunction with a heat insulation component, uniformly dries the material on the conveying device 2. This solves the problem in existing drying devices where the drying lamps are installed on both sides of the inner wall of the frame, which leads to different parts of the monocrystalline silicon rod receiving different amounts of heat during drying, resulting in uneven drying, which easily affects the production quality of the monocrystalline silicon rod and reduces the effectiveness of the monocrystalline silicon rod drying device.
