Description

Technical Field

[0001] The utility model relates to the technical field of velvet making, in particular to a groove surface exhaust structure. Background Art

[0002] Texturing of solar cells refers to the process of brightening and matting the silicon wafers covered with an oxide layer. The texturing process includes:

[0003] a. Pre-cleaning: silicon oxide surface treatment;

[0004] b. Cleaning: remove surface dirt and organic matter;

[0005] c. Texturing: The silicon wafer is matted by flowing chemical agents. The chemical reaction formula is:

[0006] 2NaOH+Si+H2O=NaSiO3+H2↑.

[0007] During the texturing process, a large amount of H2 byproduct is produced. If this H2 is not extracted in time, it will accumulate on the liquid surface, affecting the reaction rate. Furthermore, due to the fact that H2 is a hazardous gas, the high temperature of the liquid in the reaction tank, and the complex process environment that makes it difficult to eliminate static electricity, it poses a safety hazard. Currently, the exhaust structure of the texturing process is located outside the reaction tank. Because the tank body and tank cover are sealed to the liquid surface inside the tank, gas exchange and exhaust of the H2 generated during the texturing process only occur when the texturing process ends, the tank cover is opened, and the robot replaces the basket filled with silicon wafers. This operation prevents the timely discharge of this H2. Utility Model Content

At the same time, since the generated H2 is extracted in time, it will not remain in the tank body, which can improve the safety of the texturing process.

[0011] Furthermore, there are a plurality of through holes, which are evenly spaced and distributed on the exhaust pipe. Thus, the plurality of through holes can improve the exhaust efficiency of H2.

[0012] Furthermore, one end of the exhaust pipe is provided with a plug, thereby ensuring that H2 can flow to one side of the blower.

[0015] Furthermore, the card holder is provided with a card slot, and the exhaust pipe is inserted into the card slot and connected to the card holder, thereby facilitating the installation of the exhaust pipe into the card holder through the card slot.

[0016] Furthermore, the other end of the exhaust pipe is connected to the connecting pipe through a mounting joint.

[0033] like Figures 1 to 6 The figure shown is the optimal embodiment of the present invention. The trough surface exhaust structure of this embodiment includes: a trough body 1, an exhaust pipe 2 and a blower 3. The exhaust pipe 2 is installed in the trough body 1. The exhaust pipe 2 is provided with a through hole 201. The blower 3 is located outside the trough body 1 and is connected to the exhaust pipe 2. Therefore, when making the texturizing process, the blower 3 is started to extract the H2 generated in the trough body 1 through the exhaust pipe 2. Compared with the method of opening the trough cover 101 to discharge the H2, this method can promptly extract the H2 generated in the texturizing process because the exhaust pipe 2 is located in the trough body 1, thereby improving the reaction rate of the texturizing process. At the same time, since the generated H2 is promptly extracted, it will not be retained in the trough body 1, which can improve the safety of the texturizing process.

[0034] In this embodiment, multiple through holes 201 are provided, and the multiple through holes 201 are evenly spaced and distributed on the exhaust pipe 2. A plug 202 is provided at one end of the exhaust pipe 2. Thus, the multiple through holes 201 can improve the exhaust efficiency of H2 and ensure that H2 can flow to one side of the blower 3.

[0035] In this embodiment, the apparatus further comprises a connecting pipe 4, which passes through the tank body 1 and has two ends connected to the other end of the exhaust pipe 2 and the blower 3. For example, the connecting pipe 4 is a steel hose.

[0036] In this embodiment, the device further comprises: a plurality of latches 5, which are evenly spaced and distributed inside the tank body 1. The latches 5 are connected to the tank body 1. The latches 5 are provided with latching slots 501. The exhaust pipe 2 is inserted into the latching slots 501 and connected to the latches 5. Thus, the latching slots 501 facilitate installation of the exhaust pipe 2 into the latches 5.

[0037] In this embodiment, the other end of the exhaust pipe 2 is connected to the connecting pipe 4 through the installation joint 6.

[0038] In this embodiment, it also includes: a throat frame 7 and a valve 8. The throat frame 7 and the valve 8 are both located outside the tank body 1. The throat frame 7 is connected to the tank body 1. The connecting pipe 4 passes through the throat frame 7. The valve 8 is installed on the connecting pipe 4.

[0039] In this embodiment, there are two exhaust pipes 2 , which are respectively located on both sides of the tank surface of the tank body 1 . A tank cover 101 is provided on the top of the tank body 1 , and the exhaust pipes 2 are located below the tank cover 101 .

[0040] The H2 discharge process of the utility model is: when texturing, the silicon wafer is placed in the tank body 1, and the tank cover 101 is closed, the valve 8 is opened and the blower 3 is started, and the generated H2 will flow into the exhaust pipe 2 through the through hole 201, and pass through the connecting pipe 4 and the blower 3 in turn, and finally be discharged.

[0041] To sum up, during texturing, the present invention starts the blower 3 and extracts the H2 generated in the tank body 1 through the exhaust pipe 2. Compared with the method of opening the tank cover 101 to discharge H2, this method can extract the H2 generated in the texturing process in time because the exhaust pipe 2 is located in the tank body 1, thereby improving the reaction rate of the texturing process. At the same time, since the generated H2 is extracted in time, it will not remain in the tank body 1, which can improve the safety of the texturing process.

[0042] 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.
