Detailed Implementation
[0023] Referring to the accompanying drawings and specific embodiments, the structure, composition, features and advantages of a drying tank and drying device of the present invention will be described below by way of example. However, all descriptions should not be construed as limiting the present invention in any way.
[0024] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the various drawings, the present invention still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle. Therefore, these further embodiments according to the present invention should also be considered within the scope of the description herein.
[0025] It should also be noted that the terms "upper," "lower," "bottom," and "vertical," etc., indicate the direction or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this disclosure. In the description of this application, the "two sides of the tank" refers to the two sides of the wind direction V.
[0026] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.
[0027] In the words "supply wind" and "blow wind," "wind" is also equivalent to gas.
[0028] In some embodiments, the capacity of the photovoltaic trough device drying tank is increased from accommodating 4 baskets to accommodating 6 baskets, the increase in the number of baskets accommodated by the drying tank brings an increase in time productivity and use efficiency, while also bringing challenges to the process effect of the tank body. The drying tank accommodating 4 baskets has a small volume and a short drying time, and the process effect is good. The drying tank accommodating 6 baskets has an increased tank body space, and the basic structure of the drying tank is basically unchanged. The number of fans and the power of the heater are increased. However, due to the large tank body space, the tank body is a plate made of PVDF material and welded together. Due to the material properties, the tank body has poor thermal insulation, especially during the process of grabbing and placing the basket by the mechanical arm after opening the tank cover. The tank body inside will obviously cool down, which will slow down the heating after cooling down, seriously affecting the drying effect of the drying tank, delaying and increasing the drying time, resulting in low efficiency of the drying tank. At present, the only way to deal with this phenomenon is to extend the drying time and increase the number of drying tanks. However, this will lead to an increase in equipment energy consumption and operating costs. In summary, the following problems exist:
[0029] 1. The large volume of the tank body slows down the heating, affecting the drying effect;
[0030] 2. Increasing the drying time requires an increase in energy consumption;
[0031] 3. Increasing the process time requires more tank bodies to be configured, resulting in an increase in equipment production costs and an increase in equipment size, affecting the layout of the workshop.
[0032] Therefore, the present application provides another kind of drying tank for blowing and drying a plurality of silicon wafers carried in a basket. The drying tank is described below through specific embodiments.
[0033] Figures 1 to 4 The structure of the drying tank and its components according to the embodiments of the present application is shown.
[0034] As Figures 1 to 4 shown, the present application provides a drying tank, which comprises: a tank body 10, the tank body 10 is provided with a plurality of placing positions for accommodating baskets 20; a telescopic air wall 30 is arranged in the tank body 10, the telescopic air wall 30 is located between two adjacent placing positions, and the telescopic air wall 30 is provided with a plurality of air outlets 30K; when the telescopic air wall 30 is working, the conduit sends hot air into the telescopic air wall 30, the telescopic air wall 30 is extended, and the air outlets 30K of the telescopic air wall 30 blow hot air outward, which can blow and dry the baskets 20; and a conduit, which communicates with the telescopic air wall and provides air for the telescopic air wall.
[0035] As the capacity of the slot body needs to be increased, the slot body needs to be large enough to accommodate multiple flower baskets. In order to fully dry the silicon wafers in the flower baskets 20 located in the middle of the slot body 10, the retractable air walls 30 are arranged between the adjacent flower baskets 20. When the retractable air walls 30 are working, the retractable air walls 30 are extended, and the air outlets of the retractable air walls 30 blow air to the adjacent flower baskets 20. In this way, the silicon wafers in the flower baskets 20 located in the middle of the slot body 10 can also be fully dried. When the retractable air walls 30 are not working (or not opened), or in other words, when no air is flowing through the retractable air walls 30, the retractable air walls are in a retracted state.
[0036] In other embodiments, the cold air can also be sent through the duct.
[0037] As Figure 3 shown, the drying slot is provided with six placement positions for accommodating the flower baskets 20. The six placement positions are arranged in a manner of two rows and three columns, and each of the six placement positions in the figure is provided with a flower basket 20. One retractable air wall 30 is arranged between every two placement positions. As shown in the figure, the first retractable air wall 301, the second retractable air wall 302, the third retractable air wall 303, and the fourth retractable air wall 304 are provided. In other words, in the working state, during drying, there is one retractable air wall between every two flower baskets 20, and the retractable air wall 30 is provided with air outlets 30K. When the retractable air wall 30 is working, the duct sends hot air into the retractable air wall 30, the retractable air wall 30 is extended, and the air outlets 30K of the retractable air wall 30 blow hot air to both sides. The air outlets 30K of the retractable air wall 30 blow hot air to the flower baskets 20 located on both sides, so as to dry the silicon wafers carried in the flower baskets 20.
[0038] The above-described embodiment is exemplified by a drying slot accommodating six flower baskets. In embodiments not shown, other drying slots accommodating multiple flower baskets can also be used, which are not limited here.
[0039] As Figure 4As shown, the bottom of the tank 10 is provided with a support plate 107, which supports the telescopic air walls 30 on the upper side, and the lower side of the support plate 107 is provided with a conduit, which includes a tank bottom air pipe 104 and two branch pipes 106 communicating with the tank bottom air pipe 104, and the two branch pipes 106 respectively pass through the support plate 107 to communicate with an adjacent group of telescopic air walls (i.e. two telescopic air walls in the figure), such as the first telescopic air wall 301 and the fourth telescopic air wall 304. A valve 105 is arranged on the tank bottom air pipe 104, so that the hot air to the first telescopic air wall 301 and the fourth telescopic air wall 304 can be simultaneously opened or closed. In the figure not shown, there is another group of tank bottom air pipes 104 and two branch pipes 106 communicating with the tank bottom air pipe 104, and the two branch pipes 106 respectively pass through the support plate 107 to communicate with an adjacent group of telescopic air walls (i.e. two telescopic air walls in the figure), that is, the second telescopic air wall 302 and the third telescopic air wall 303, and similarly, another valve is arranged on the tank bottom air pipe 104, so that the air to the second telescopic air wall 302 and the third telescopic air wall 303 can be simultaneously opened or closed. That is, two valves are arranged in the space on the lower side of the support plate 107 of the tank 10, respectively controlling the ventilation of the two groups of telescopic air walls. The placing position of the flower basket is also on the upper side of the support plate 107.
[0040] In the embodiment not shown, the interface of the telescopic air wall can pass through the support plate 107 and then communicate with the branch pipe 106.
[0041] In the embodiment not shown, the conduit includes a tank bottom air pipe and four branch pipes communicating with the tank bottom air pipe, each branch pipe communicates with one telescopic air wall, and one valve is arranged on the tank bottom air pipe, so that one valve simultaneously opens or closes the hot air to the four telescopic air walls.
[0042] In the embodiment not shown, part of the two adjacent placing positions can also not be provided with telescopic air walls.
[0043] When there is no flower basket 20 in the tank, the valves 105 are all in the closed state. When there is a flower basket 20 in the tank, during drying, the valves 105 are opened, the hot air enters the branch pipes 106 through the tank bottom air pipe 104, and then the hot air enters the telescopic air walls inside the tank through the branch pipes 106. At this time, the telescopic air walls will stand up, and the hot air passing through the air outlet holes of the telescopic air walls will dry the adjacent flower baskets. Since the telescopic air walls are close to the flower baskets, the drying effect can be increased and the drying time can be reduced.
[0044] Further, the drying tank also comprises a gas collecting cavity 102, the gas collecting cavity 102 is connected with the air inlet pipe 101, the hot air is provided to the gas collecting cavity 102 through the air inlet pipe 101 in the direction V. The two tank bottom air pipes 104 are communicated with the gas collecting cavity 102. The supplied hot air passes through the air inlet pipe 101, and then passes through the gas collecting cavity 102, the tank bottom air pipe 104 and the branch pipe 106 in sequence, and then the hot air is sent into the telescopic air wall. The hot air passes through the air outlet hole of the telescopic air wall to dry the adjacent flower basket.
[0045] Further, the tank body has side plates 10C on both sides, and adjacent positions on the inner side of the side plates 10C on both sides are provided with telescopic air walls 10B. Figure 4 The three tank inner air pipes 103 are arranged in sequence in the vertical direction, and a total of six tank inner air pipes 103 are arranged on both sides. A plurality of air outlet holes 103K are arranged on each tank inner air pipe 103, so that the air can pass through the plurality of tank inner air pipes 103 to blow and dry the flower basket through the plurality of air outlet holes 103K of the tank inner air pipes 103 from both sides of the tank body. The six tank inner air pipes 103 are communicated with the gas collecting cavity 102, the supplied hot air passes through the air inlet pipe 101, and then passes through the gas collecting cavity 102 and the tank inner air pipe 103 in sequence to enter the inside of the tank body. The hot air passes through the air outlet hole 103K of the tank inner air pipe 103 to dry the inside of the tank body.
[0046] In the above embodiment, the hot air first passes through the gas collecting cavity 102 before entering the tank body 10, and the gas collecting cavity 102 has the functions of pressure equalization and pressure stabilization, which avoids the direct air supply of the air supply device to the tank body 10, thereby avoiding the unstable air pressure and the vibration and noise of the drying tank caused by the unstable air pressure.
[0047] Further, the tank body is made of PVDF material, and the tank body can be welded.
[0048] The valve 105 described above is a pneumatic valve, which is used to open or close the air to the telescopic air wall. The valve 105 can also be other types of valves, as long as it can be used to open or close the air to the telescopic air wall, which is not limited here.
[0049] The specific operation state of the drying tank in the above embodiment is described as follows: ① When there is no flower basket 20 placed in the inside of the tank body 10, that is, the drying tank is not in the working state, the two valves 105 at the bottom of the tank body are in the closed state, the hot air passes through the air inlet pipe 101 into the gas collecting cavity 102 in the direction V, and then the hot air is transported into the inside of the tank body 10 through the six tank inner air pipes 103 connected with the gas collecting cavity 102, so as to maintain the temperature in the tank body 10.
[0050] When the groove body has the flower basket 20 to carry out the drying process, that is, the drying groove is in the working state, the hot air enters the air collecting cavity 102 through the air inlet pipe 101, and is transported into the groove body through the groove internal ventilation pipe 103 connected with the air collecting cavity 102 to dry the flower basket, when drying for 200s, the two valves 105 at the bottom of the groove body are opened, the hot air enters the branch pipe 106 through the groove bottom ventilation pipe 104, and then enters the telescopic air wall 30 in the groove body through the branch pipe 106, at this time, the telescopic air wall 30 is erected, the hot air passes through the air outlet hole 30K of the telescopic air wall 30 to dry the flower basket nearby, since the telescopic air wall 30 is close to the flower basket 20, the drying effect can be increased, and the drying time can be reduced.
[0051] When the drying process in the groove body is completed, the two valves 105 at the bottom of the groove body are closed, the hot air enters the air collecting cavity 102 through the air inlet pipe 101, and is transported into the groove body 10 through the six groove internal ventilation pipes 103 connected with the air collecting cavity 102 to keep the temperature in the groove body.
[0052] In another embodiment of the application, a drying device is provided, which comprises the blowing mechanism and the drying groove described above; the blowing mechanism is connected to the drying groove to supply hot air to the drying groove.
[0053] The technical scope of the application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the application, and these modifications and changes should be within the scope of the application.
