Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silicon wafer drying, in particular to a flower basket bottom rod drying device. Background Art
[0002] During the solar cell production process, silicon wafers undergo a series of processes, including texturing, diffusion, etching, coating, and printing. During the texturing process, the silicon wafers are immersed in a reaction solution to corrode the surface, forming a textured surface. After texturing, the wafers need to be dried during the diffusion process. Therefore, after the texturing process, the silicon wafers must be cleaned and dried to remove water stains on the surface to ensure their quality and performance.
[0003] In photovoltaic trough cleaning equipment, drying is the last step in the equipment process. Currently, silicon wafers are dried using sidewall drying (i.e., the drying trough uses sidewall blowing to dry silicon wafers). A drying pipe is installed on the inner wall of the drying trough, and air is blown from the inner wall to the basket containing the silicon wafers (the basket serves as the carrier of the silicon wafers during the drying process). This drying method uses air intake through the inner wall pipe of the drying trough and air outlet from the bottom of the drying trough. This drying method easily causes the basket near the air outlet to be difficult to dry due to its distance from the air inlet. In addition, the silicon wafers are located above the bottom rod of the basket, which is the lowest point where water gathers and flows. Therefore, the bottom rod of the basket will be liquid-carrying, resulting in long drying time and poor drying effect. Utility Model Content
[0004] The technical problem to be solved by the present invention is: in order to solve the technical problem of long drying time and poor drying effect of the existing silicon wafer side wall drying method, the present invention provides a flower basket bottom rod drying device, which can avoid liquid on the flower basket bottom rod by improving the silicon wafer drying method, shorten the silicon wafer drying time, and improve the silicon wafer drying effect.
[0005] The technical solution adopted by the utility model to solve the technical problem is: a flower basket bottom rod drying device, comprising: a fan, an air inlet pipe and a ventilation hole, the inlet end of the air inlet pipe is connected to the outlet end of the fan, and the ventilation hole is provided on the air inlet pipe; wherein: the air inlet pipe is located below the flower basket, and the ventilation hole is provided on the side of the air inlet pipe facing the flower basket.
[0006] Therefore, the design method of the ventilation holes being located below the flower basket adopts a bottom-up blowing method to dry the flower basket. Compared with the side wall drying method, this method has a simple structure and is easy to operate. It can directly apply the drying air to the bottom rod of the flower basket, ensuring that after the silicon wafers are dried, the bottom rod of the flower basket will not carry any liquid, which can shorten the drying time of the silicon wafers and improve the drying effect of the silicon wafers.
[0007] Furthermore, it also includes: a blowing pipe, the blowing pipe is connected to the outlet end of the air inlet pipe, and the ventilation hole is opened on the side of the blowing pipe facing the flower basket.

Thus, each bottom rod can be equipped with a blowing pipe to carry out targeted drying operations on the bottom rods, thereby further shortening the drying time of the silicon wafers and improving the drying effect of the silicon wafers.
[0009] Furthermore, the blowing pipe is located directly below the bottom rod, thereby shortening the effective distance of the blowing. Compared with other staggered blowing methods, this method can maximize the drying effect of the blowing, thereby further shortening the drying time of the silicon wafer and improving the drying effect of the silicon wafer.
[0010] Furthermore, each of the blowing pipes is provided with a plurality of ventilation holes, and the plurality of ventilation holes are distributed at equal intervals, thereby being able to complete the drying operation of the entire bottom bar.
[0011] Furthermore, the device further comprises a heater, wherein the inlet end of the heater is connected to the outlet end of the fan, and the outlet end of the heater is connected to the inlet end of the air inlet pipe. Thus, the air generated by the fan can be heated, and the heated air is applied to the basket to dry the silicon wafers.
[0012] Furthermore, the device further comprises: a valve, which is connected in series to the outlet end of the heater, so that the ventilation volume of the ventilation hole can be adjusted through the valve.
[0013] Furthermore, it also includes: a hose, both ends of which are respectively connected to the outlet end of the heater and the inlet end of the air inlet pipe.
[0014] Furthermore, it also includes: a drying box, the blowing pipe is located inside the drying box, the air inlet pipe runs through the drying box, and the fan and the heater are both located outside the drying box and connected to the drying box.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0026] like Figures 1 to 4 The figure shows a preferred embodiment of the present invention. The flower basket bottom rod drying device of this embodiment comprises: a fan 1, an air inlet pipe 2, and a vent 3. The inlet end of the air inlet pipe 2 is connected to the outlet end of the fan 1, and the vent 3 is formed in the air inlet pipe 2. The air inlet pipe 2 is located below the flower basket 4, and the vent 3 is formed on the side of the air inlet pipe 2 facing the flower basket 4. Thus, the design of the vent 3 below the flower basket 4 adopts a bottom-up air blowing method to dry the flower basket 4. Compared with the side wall drying method, this method is simpler in structure and easier to operate. It can directly apply the drying air to the bottom rod 401 of the flower basket 4, ensuring that the bottom rod 401 of the flower basket 4 is free of liquid after the silicon wafers 402 are dried. This can shorten the drying time of the silicon wafers 402 and improve the drying effect of the silicon wafers 402.
[0027] In other words, the side wall drying method is not easy to dry because the flower basket 4 close to the air outlet is closer to the air inlet, and the silicon wafer 402 is located above the bottom rod 401 of the flower basket 4. During the drying operation, the bottom rod 401 of the flower basket 4 is the lowest point where water gathers and flows. If the side wall drying method is adopted, after the silicon wafer 402 is dried, the bottom rod 401 of the flower basket 4 will still have liquid. However, the present application blows air from top to bottom through the ventilation hole 3, which can directly act on the bottom rod 401 of the flower basket 4 (that is, the bottom rod 401 is first exposed to the air), and the downward flow direction of the liquid intersects with the upward flow direction of the air, which can improve the effect of the air blowing, thereby shortening the drying time of the silicon wafer 402 and improving the drying effect of the silicon wafer 402.
[0028] It should be noted that: Figure 4 As shown, the flower basket 4 serves as a carrier for the silicon wafers 402. When drying the silicon wafers 402, the silicon wafers 402 are placed on the flower basket 4 and then dried, rather than stacking multiple silicon wafers 402 for drying.
[0029] In this embodiment, the apparatus further includes: a blow pipe 5, which is connected to the outlet end of the air inlet pipe 2; a ventilation hole 3 is provided on the side of the blow pipe 5 facing the flower basket 4; a plurality of blow pipes 5 are provided; wherein: the number of blow pipes 5 is equal to the number of bottom bars 401; and the blow pipes 5 are located directly below the bottom bars 401. Thus, each bottom bar 401 can be equipped with a blow pipe 5, so that the bottom bars 401 can be dried in a targeted manner, thereby further shortening the drying time of the silicon wafers 402 and improving the drying effect of the silicon wafers 402; and the effective distance of the blowing air can be shortened. Compared with other staggered blowing methods, this method can maximize the drying effect of the blowing air, thereby further shortening the drying time of the silicon wafers 402 and improving the drying effect of the silicon wafers 402.
[0030] In other words, when the ventilation hole 3 is blowing air, its effect is strongest in the middle position and gradually weakens at the edge position. In this way, the design of the blowing pipe 5 being located directly below the bottom rod 401 can maximize the effect of the blowing pipe 5.
[0031] In this embodiment, each blowing pipe 5 is provided with a plurality of ventilation holes 3, and the plurality of ventilation holes 3 are distributed at equal intervals, thereby being able to complete the drying operation of the entire bottom bar 401.
[0032] This embodiment further includes a heater 6, a valve 7, and a hose 8. The inlet of the heater 6 is connected to the outlet of the fan 1, which in turn is connected to the inlet of the air inlet pipe 2. The valve 7 is connected in series to the outlet of the heater 6, and the ends of the hose 8 are connected to the outlet of the heater 6 and the inlet of the air inlet pipe 2, respectively. This allows the air generated by the fan 1 to be heated, and the heated air is applied to the flower basket 4 to dry the silicon wafers 402. The valve 7 can be used to adjust the ventilation volume of the vent 3.
[0033] In this embodiment, it also includes: a drying box 9, the blowing pipe 5 is located inside the drying box 9, the air inlet pipe 2 runs through the drying box 9, the fan 1 and the heater 6 are both located outside the drying box 9 and connected to the drying box 9.
[0034] The drying process of the silicon wafers 402 of the present invention is as follows: first, the oven door (not shown) is opened, the flower basket 4 to be dried is placed into the drying oven 9, and the oven door is closed; then, the fan 1 and heater 6 are started, and the valve 7 is opened to adjust the ventilation volume of the ventilation hole 3 to dry the silicon wafers 402; finally, after the silicon wafers 402 are dried, the oven door is opened and the dried flower basket 4 is removed.
[0035] To sum up, the ventilation hole 3 of the utility model is designed to be located below the flower basket 4, and the flower basket 4 is dried by blowing air from bottom to top. Compared with the side wall drying method, this method has a simple structure and is easy to operate. The drying air can be directly applied to the bottom rod 401 of the flower basket 4 to ensure that after the silicon wafer 402 is dried, the bottom rod 401 of the flower basket 4 will not carry any liquid, which can shorten the drying time of the silicon wafer 402 and improve the drying effect of the silicon wafer 402.
[0036] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model. The technical scope of this utility model is not limited to the content of the specification and must be determined according to the scope of the claims.
