Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic wet trough cleaning equipment, specifically a drying structure for photovoltaic wet trough cleaning equipment. Background Technology

[0002] In the photovoltaic cell manufacturing process, silicon wafer cleaning is a crucial step. Currently, wet cleaning equipment is typically used to chemically treat silicon wafers to achieve processes such as etching and texturing on the surface of the silicon wafers. After wet cleaning, hot air is blown onto the surface of the silicon wafers to accelerate the evaporation of moisture using high temperature, thereby removing residual moisture and achieving a drying effect.

[0003] A published Chinese patent, publication number CN221259293U, discloses a drying tank for silicon wafers, including an outer tank body comprising a first base plate, a first outer plate, and a second outer plate. The first and second outer plates are disposed opposite each other on both sides of the first base plate to form a first inner cavity. An inner tank body is disposed in the first inner cavity of the outer tank body. The inner tank body includes a second base plate, a first flow equalizing plate connected to one side of the second base plate, and a second flow equalizing plate connected to the other side of the second base plate. The second base plate, the first flow equalizing plate, and the second flow equalizing plate are used to form a second inner cavity for accommodating a basket. The first flow equalizing plate and the first outer plate are spaced apart to form a first air inlet channel. The second base plate and the first base plate are spaced apart to form a second air inlet channel. The second flow equalizing plate and the second outer plate are spaced apart to form an air outlet channel. A guide hole for connecting the second inner cavity and the second air inlet channel is provided at one end of the second base plate near the air outlet channel.

[0004] The drying tank provided by the disclosed patent only sends air to the bottom of the basket through the guide holes on the second base plate, which cannot achieve full coverage of the silicon wafer and the bottom of the basket. In particular, the contact area between the bottom of the basket and the front and rear support structures is prone to forming drying dead corners, resulting in moisture residue. Utility Model Content

[0005] The purpose of this invention is to provide a drying structure for a photovoltaic wet trough cleaning device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drying structure for a photovoltaic wet trough cleaning device, including a shell with a drying chamber inside, and symmetrical support seats for fixing flower baskets on both sides of the bottom of the drying chamber; The bottom of the drying chamber is provided with a first air inlet assembly for drying the bottom of the silicon wafer, the bottom of the basket, and the dead corner between the basket and the left and right support seats. The front and rear inner walls of the drying chamber are respectively provided with a second air inlet assembly for drying the entire silicon wafer and an air outlet assembly for discharging hot air. The first air intake assembly includes a longitudinal air intake pipe and a transverse air intake pipe. Several longitudinal air intake pipes are distributed in parallel between the two side supports to cover the required drying area of ​​all silicon wafers and the bottom of the basket. Several transverse air intake pipes are located on the opposite side of the support to cover the drying dead corner where the basket connects to the support.

[0007] In one embodiment of the present invention, a first T-shaped air collecting pipe is provided between two adjacent longitudinal air inlets, and a second T-shaped air collecting pipe is provided between two adjacent transverse air inlets. The bottom of the drying chamber is provided with a plurality of first air inlets for connection to a hot air blower. The bottom ends of the first T-shaped air collecting pipe and the second T-shaped air collecting pipe are connected to the corresponding first air inlets.

[0008] In one embodiment of the present invention, the top of the longitudinal air inlet pipe is provided with a plurality of longitudinal air inlet holes at equal intervals, and the side of the transverse air inlet pipe facing the support base is provided with a plurality of transverse air inlet holes at equal intervals.

[0009] In one embodiment of the present invention, the second air inlet assembly includes a lateral air inlet pipe, a fixing plate, and an air collection chamber. A plurality of the lateral air inlet pipes are sequentially installed on the fixing plate from top to bottom and fixed to the inner wall of the front side of the drying chamber. A plurality of lateral air inlet holes are equidistantly opened on the side of the lateral air inlet pipe facing the drying chamber. The bottom ends of the air collection chambers on both sides are connected to a second air inlet for connection with a hot air blower. Both ends of the lateral air inlet pipes are connected to the air collection chambers.

[0010] In one embodiment of the present invention, the air outlet assembly includes an air outlet plate and a trapezoidal cavity. The air outlet plate is disposed on the front side of the rear inner wall of the drying chamber to form a relatively closed air outlet cavity. A plurality of drainage holes are equally spaced on the air outlet plate. The trapezoidal cavity is disposed at the bottom of the air outlet cavity, and an air outlet is connected to the bottom of the trapezoidal cavity.

[0011] In one embodiment of the present invention, the longitudinal air inlet pipe and the transverse air inlet pipe are fixed to the bottom of the drying chamber by a mounting base, and the outer surface of the shell is provided with reinforcing ribs.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting up a first air inlet component, the hot air blower efficiently diverts hot air to several parallel longitudinal air inlets and a transverse air inlet on one side of the support base through the first air inlet, the first T-shaped air collection pipe and the second T-shaped air collection pipe. The longitudinal air inlets fully cover all the silicon wafers and the drying area required at the bottom of the basket. The transverse air inlets precisely target the dead corner where the basket and the support base are connected, solving the problem of moisture residue at the bottom and contact parts in the traditional structure, ensuring that the silicon wafers can be dried in all directions after cleaning, and improving the drying efficiency. (2) By setting up a second air inlet component and an air outlet component, the hot air delivered by the hot air blower can enter the air collection chamber through the second air inlet and then be diverted to the side air inlet pipe of the second air inlet component to blow and dry the silicon wafers of various heights from the side. The tubular structure of the side air inlet pipe replaces the air inlet plate structure of the traditional drying tank, avoiding the air inlet plate structure from being affected by high temperature hot air for a long time and causing expansion and deformation. After the blowing and drying is completed, the hot air enters the air outlet chamber through the drainage hole on the air outlet plate, and then enters the trapezoidal cavity and is discharged from the air outlet. This design combined with the hot air blower improves the structural stability of the equipment in the long-term high temperature operation environment and extends the service life of the structure.

[0014] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0015] This utility model provides a technical solution: a drying structure for a photovoltaic wet trough cleaning device, including a shell 20 with an internal drying chamber 10. Symmetrical support seats 11 for fixing the basket are provided on both sides of the bottom of the drying chamber 10; the support seats 11 can stably fix the basket, providing a stable foundation for subsequent drying. A first air inlet assembly 30 is provided at the bottom of the drying chamber 10 for drying the bottom of the silicon wafer, the bottom of the basket, and the dead corners between the basket and the left and right support seats 11. A second air inlet assembly 40 for drying the entire silicon wafer and an air outlet assembly 50 for discharging hot air are respectively provided on the front and rear inner walls of the drying chamber 10. The first air inlet assembly 30, the second air inlet assembly 40, and the air outlet assembly 50 work together to form a good hot air circulation, further improving drying efficiency and effect, and ensuring the drying quality of the silicon wafer after wet cleaning. The first air intake assembly 30 includes a longitudinal air intake pipe 31 and a transverse air intake pipe 32. Several longitudinal air intake pipes 31 are distributed in parallel between the two side support bases 11 to cover the required drying area of ​​all silicon wafers and the bottom of the basket, ensuring that the bottom of the silicon wafers and the bottom of the basket can be fully heated by hot air. Several transverse air intake pipes 32 are located on the opposite side of the support base 11 to cover the drying dead corner where the basket connects to the support base 11, effectively avoiding the problem of moisture residue caused by the drying dead corner not being fully dried by hot air.

[0016] A first T-shaped air collecting pipe 311 is provided between two adjacent longitudinal air inlet pipes 31, and a second T-shaped air collecting pipe 321 is provided between two adjacent transverse air inlet pipes 32. Several first air inlets 12 for connection to a hot air blower are opened parallel to each other at the bottom of the drying chamber 10. The bottom ends of the first T-shaped air collecting pipes 311 and the second T-shaped air collecting pipes 321 are connected to the corresponding first air inlets 12. The hot air generated by the hot air blower can enter the first T-shaped air collecting pipes 311 and the second T-shaped air collecting pipes 321 through the first air inlets 12 respectively, and then the air collecting pipes will evenly distribute the hot air to each longitudinal air inlet pipe 31 and transverse air inlet pipe 32. This design avoids the dispersion and loss of hot air during the transportation process, and ensures that each air inlet pipe can obtain stable and sufficient hot air. This makes the drying of the silicon wafer and the bottom of the basket by the longitudinal air inlet pipe 31 and the drying of the basket and the dead corner of the support base 11 by the transverse air inlet pipe 32 more uniform and efficient, further improving the overall drying effect and reducing the problem of incomplete drying caused by uneven hot air supply. The top of the vertical air inlet duct 31 has several vertical air inlet holes 312 at equal intervals; the vertical air inlet holes 312 allow the hot air entering the vertical air inlet duct 31 to be blown out evenly from the top, thereby providing comprehensive and uniform drying of the silicon wafer and the bottom of the basket. The side of the horizontal air inlet duct 32 facing the support base 11 has several horizontal air inlet holes 322 at equal intervals; the horizontal air inlet holes 322 allow the hot air entering the horizontal air inlet duct 32 to be blown precisely and evenly to the dead corner where the basket connects to the support base 11, ensuring that every corner of this area receives sufficient hot air.

[0017] The second air inlet assembly 40 includes a lateral air inlet pipe 41, a fixing plate 42, and an air collection chamber 43. Several lateral air inlet pipes 41 are sequentially installed from top to bottom on the fixing plate 42 and fixed to the inner front wall of the drying chamber 10. This installation method ensures the stability of the lateral air inlet pipes 41 and allows them to fully cover the silicon wafers in the height direction, ensuring that silicon wafers of different heights are all affected by hot air. Several lateral air inlet holes 411 are equidistantly opened on the side of the lateral air inlet pipe facing the drying chamber 10. The lateral air inlet holes 411 allow the hot air entering the pipe to be blown out evenly, avoiding uneven drying caused by excessively strong or weak local hot air. Both sides of the air collection chamber 43 are connected to a second air inlet 431 for connection with the hot air blower. The two ends of the side air inlet pipe 41 are connected to the air collection chamber 43. The hot air delivered by the hot air blower can first enter the air collection chamber 43 for buffering and distribution, and then be evenly delivered to each side air inlet pipe 41, ensuring that the hot air supply of each side air inlet pipe 41 is consistent.

[0018] The air outlet assembly 50 includes an air outlet plate 51 and a trapezoidal cavity 52. ​​The air outlet plate 51 is located on the front side of the rear inner wall of the drying chamber 10 to form a relatively closed air outlet cavity. This provides a dedicated space for the convergence and discharge of hot air, avoiding energy waste caused by the disorderly flow of hot air within the drying chamber 10. Several drainage holes 511 are equidistantly provided on the air outlet plate 51, which can guide the hot air in the drying chamber 10 to enter the air outlet cavity evenly, ensuring that hot air from different areas can be discharged in a timely manner. The trapezoidal cavity 52 is located at the bottom of the air outlet cavity, and an air outlet 521 is connected to the bottom of the trapezoidal cavity 52. ​​The trapezoidal cavity 52 can converge and guide the discharged hot air, allowing the hot air to be discharged more smoothly through the air outlet 521 connected to the bottom, enhancing the stability of the air outlet.

[0019] The longitudinal air inlet pipe 31 and the transverse air inlet pipe 32 are fixed to the bottom of the drying chamber 10 by the mounting base 13; the mounting base 13 ensures that the air inlet pipes maintain a stable position during hot air delivery and avoids displacement due to airflow impact or equipment vibration. The outer surface of the shell 20 is provided with reinforcing ribs 21; the reinforcing ribs 21 effectively improve the structural strength and deformation resistance of the shell 20.

[0020] Working principle: Place the basket containing the silicon wafers on the support seats 11 on both sides of the bottom of the drying chamber 10. Then, the hot air blower is started, and the generated hot air enters the drying chamber 10 through the first air inlet 12 and the second air inlet 431 respectively. For the first air intake component 30, hot air flows into the first T-shaped air collection pipe 311 and the second T-shaped air collection pipe 321 through the first air inlet 12. The first T-shaped air collection pipe 311 evenly distributes the hot air to each longitudinal air intake pipe 31. The hot air is evenly blown towards the bottom of the silicon wafer and the bottom of the basket through the longitudinal air intake holes 312 that are equidistantly opened at the top of the longitudinal air intake pipe 31, so as to achieve comprehensive drying of these areas. At the same time, the second T-shaped air collection pipe 321 distributes hot air to each horizontal air inlet pipe 32, and the hot air is precisely blown to the dead corner where the flower basket and the support base 11 are connected through the horizontal air inlet hole 322. For the second air intake assembly 40, the hot air delivered by the hot air blower enters the air collection chamber 43 through the second air inlet 431. After the air collection chamber 43 buffers and distributes the hot air, it is evenly delivered to each side air intake pipe 41. Then the hot air is evenly blown out through the side air intake hole 411 to blow and bake the silicon wafer as a whole, and can cover silicon wafers of different heights. During the entire drying process, the air outlet assembly 50 works synchronously. The hot air in the drying chamber 10 enters the relatively closed air outlet cavity through the guide hole 511 on the air outlet plate 51. Then the hot air converges in the trapezoidal cavity 52 at the bottom of the air outlet cavity. The trapezoidal cavity 52 guides the hot air, allowing the hot air to be smoothly discharged from the drying chamber 10 through the air outlet 521, forming a complete hot air flow circulation.
