Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning tank. Background Technology

[0002] In the manufacturing process of solar cells, the graphite boat plays a crucial role as a carrier, and the cleanliness of the graphite boat has a significant impact on the quality of the solar cells and the stable output of the solar cells.

[0003] However, existing spray cleaning tanks have many drawbacks: side spraying with graphite boats suffers from uneven coverage, insufficient cleaning, and poor control of chemical contamination. For example, a cleaning blind zone forms on the back of the graphite boat blades, the impact pressure decreases from the nozzle to the opposite side, and the side-sprayed fluid impacts the boat blades, creating reflected turbulence that interferes with the jets from adjacent nozzles, easily forming low-pressure dead zones in some areas. Fixed top spraying suffers from insufficient dynamic cleaning force, significant edge effects, and low nanoparticle removal rates. In addition, there are problems such as high nozzle clogging rates due to sediment accumulation in horizontal pipelines and shortened seal life due to lateral forces. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] In the manufacturing process of solar cells, the graphite boat plays an indispensable role as a carrier, and its cleanliness is crucial. The cleanliness of the graphite boat has a significant impact on the quality and stable output of the solar cells, and the current photovoltaic and semiconductor industries have increasingly stringent requirements for the cleanliness of graphite boats. However, please refer to... Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of a cleaning tank in the prior art. Figure 2 This is the second structural diagram of a cleaning tank in the existing technology. Existing spray cleaning tanks have many defects in practical applications and are difficult to meet the needs of high-precision cleaning.

[0038] First, the side spraying of the graphite boat suffers from uneven coverage. Due to limitations in nozzle position and angle, a cleaning blind spot often forms on the back of the graphite boat, preventing effective removal of impurities. The impact pressure attenuates significantly from the nozzle to the opposite surface of the graphite boat, further affecting the cleaning effect. Furthermore, the side-sprayed fluid creates reflected turbulence upon impact with the boat, interfering with the jets from adjacent nozzles and easily forming low-pressure dead zones in localized areas, resulting in even worse cleaning in these areas.

[0039] Secondly, the dynamic cleaning force of the fixed top spray is insufficient, making it difficult to generate enough impact on stubborn impurities on the graphite boat surface during the cleaning process, resulting in incomplete cleaning. Furthermore, the fixed top spray exhibits a significant edge effect, with the cleaning effect differing between the edge areas and the center areas, affecting the overall uniformity of cleaning. Finally, the fixed top spray has a low nanoparticle removal rate, which cannot meet the high cleanliness requirements of current solar cell manufacturing.

[0040] Furthermore, existing horizontal piping in spray cleaning tanks is prone to sediment accumulation, leading to high nozzle clogging rates and affecting the normal operation of the spray system. Existing spray cleaning tanks experience significant lateral stress, which can shorten the lifespan of seals and cause problems such as cleaning fluid leakage, impacting cleaning effectiveness and the stability of the cleaning tank.

[0041] In view of this, this application discloses a cleaning tank, which expands the spray range and angle of the spray mechanism by setting the spraying mechanism on a rotatable cover plate, thereby improving the cleaning coverage of the cleaning tank and ensuring the reliability of graphite boat cleaning.

[0042] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0043] Please see Figures 3 to 5 , Figure 3 This is one of the structural schematic diagrams of the cleaning tank 100 provided in the embodiments of this application. Figure 4 This is the second schematic diagram of the structure of the cleaning tank 100 provided in the embodiments of this application. Figure 5 This is a schematic diagram of the cleaning tank 100 provided in this application embodiment when closed. The first aspect of this utility model discloses a cleaning tank 100 for cleaning a graphite boat 200. The cleaning tank 100 includes: a tank body 1 with an opening at the top, and the tank body 1 is used to accommodate the graphite boat 200; a cover plate 2 covering the opening, the cover plate 2 being rotatably connected to the tank body 1 to open or close the tank body 1; and a spraying mechanism 3 disposed on the side of the cover plate 2 facing the tank body 1, so that the spraying mechanism 3 rotates with the cover plate 2, and the spraying mechanism 3 being configured to spray cleaning fluid into the accommodating cavity to clean the graphite boat 200 located within the accommodating cavity.

[0044] The top of the tank 1 has an opening, and the tank 1 is used to accommodate the graphite boat 200. The structural design of the tank 1 provides a stable environment for the cleaning fluid, while effectively reducing the evaporation and splashing of the cleaning fluid during the cleaning process, reducing the risk of pollution to the surrounding environment, and ensuring the relative enclosure and safety of the cleaning area.

[0045] The cover plate 2 covers the opening at the top of the tank 1 and is rotatably connected to the tank 1. This allows the cover plate 2 to be easily opened for the placement and removal of the graphite boat 200, while also tightly covering the opening during the cleaning process to prevent external liquid residue from dripping or foreign objects from falling into the tank 1. This avoids secondary contamination of the graphite boat 200 and greatly improves the purity and safety of the cleaning process.

[0046] In addition, the rotatability of the cover plate 2 increases the flexibility of opening and closing operations, reduces the complexity of opening and closing operations, and improves the efficiency of placing and removing the graphite boat 200.

[0047] The spraying mechanism 3 is located on the side of the cover plate 2 facing the tank 1, so that the spraying mechanism 3 can change its position and angle as the cover plate 2 rotates, so as to ensure that the spraying range of the spraying mechanism 3 covers all surfaces of the graphite boat 200, including some hard-to-reach corners and edges.

[0048] The graphite boat 200 typically has multiple boat blades arranged at intervals along its width. Traditional cleaning methods often involve spraying from the left and right sides, that is, spraying in a direction perpendicular to the boat blades. This results in the left spray mechanism 3 only covering the left side of the boat blade, and the right spray mechanism 3 only covering the right side. This design prevents both sides of the boat blades from being effectively cleaned simultaneously, resulting in a significantly insufficient coverage area. Consequently, the cleaning effect of the graphite boat 200 is unsatisfactory, failing to meet the expected cleanliness requirements and affecting the quality and efficiency of subsequent solar cell production processes.

[0049] The cleaning tank 100 provided in this application has a spraying mechanism 3 mounted on the top cover plate 2 and equipped with multiple sets of nozzles, which can fully cover the graphite boat 200 from top to bottom. This design ensures that both the left and right sides of the boat blades can be cleaned, thereby significantly improving the cleaning coverage, making the cleaning more thorough, effectively removing impurities from the surface of the graphite boat 200, and improving the cleaning effect.

[0050] Meanwhile, the top spray design avoids flow field interference problems. Traditional side spraying easily causes complex reflections and turbulence on the surface of the graphite boat 200, resulting in low-pressure dead zones in local areas and affecting the cleaning effect. However, with top spraying, all nozzles spray downwards, and the water flow force is in the same direction, so there is no mutual interference. This avoids flow field chaos and the formation of low-pressure dead zones, ensuring a stable and efficient cleaning process.

[0051] It is understandable that the cover plate 2 can stop at any angle, at which point the spraying mechanism 3 can begin spraying, thus providing great flexibility for the cleaning process of the graphite boat 200. Through this design, the spraying mechanism 3 can spray from different angles according to the specific shape of the graphite boat 200 and the cleaning requirements, ensuring that the cleaning fluid covers all surfaces of the graphite boat 200, including hard-to-reach corners and edges inside the boat. This not only improves the uniformity and coverage of cleaning but also enhances the cleaning effect of the graphite boat 200, enabling it to achieve higher cleanliness standards.

[0052] Optionally, the spraying mechanism 3 can be a single type of nozzle, such as a high-pressure water nozzle, which can provide strong impact force to effectively remove stubborn stains from the surface of the graphite boat 200; it can also be a combination of multiple nozzles, such as combining a high-pressure nozzle with a coverage nozzle, to achieve all-round, no-dead-angle cleaning of the graphite boat 200 through spraying with different shapes and angles; or it can be a nozzle with an adjustable nozzle, which allows the operator to flexibly adjust the opening angle and spray intensity of the nozzle according to the actual cleaning needs, thereby achieving the best cleaning effect.

[0053] Specifically, in actual operation, firstly, the cover plate 2 is opened, and the graphite boat 200 to be cleaned is smoothly placed into the tank 1. Then, according to the position of the graphite boat 200 and the cleaning requirements, the angle of the cover plate 2 is adjusted, and the cover plate 2 is fixed in the appropriate position. After starting the spray mechanism 3, the cleaning fluid will be evenly sprayed onto the surface of the graphite boat 200 under a certain pressure, performing a thorough rinse. The cleaning fluid circulates within the tank 1, washing away impurities on the surface of the graphite boat 200 and carrying the impurities to the bottom of the tank 1 for centralized treatment.

[0054] Thus, the cleaning tank 100 provided in this embodiment of the application, by setting the spray mechanism 3 on the movable cover plate 2, achieves a flexible spray angle adjustment function, enhances the cleaning effect on the graphite boat 200, and improves the safety and convenience of cleaning. The cleaning tank 100 cleans the graphite boat 200, providing a more reliable clean carrier for subsequent solar cell production processes, reducing the risk of contamination during the cleaning process, reducing operational difficulty, and improving production efficiency.

[0055] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of the cleaning tank 100 when it is opened according to the embodiment of this application. In some embodiments, the cleaning tank 100 further includes a rotating mechanism 4, which is connected between the tank body 1 and the cover plate 2 so that the cover plate 2 and the tank body 1 can be rotatably set through the rotating mechanism 4.

[0056] The rotating mechanism 4 provides the cover plate 2 with flexible adjustability. During the placement or removal of the graphite boat 200, the operator can easily open the cover plate 2 without additional disassembly steps, simplifying the operation process. During the cleaning process, the closed state of the cover plate 2 can prevent the splashing of cleaning fluid and the intrusion of external impurities, thereby ensuring the stability of the cleaning environment and the reliability of the cleaning effect.

[0057] Secondly, the rotating mechanism 4 provides a basis for adjusting the position and angle of the spraying mechanism 3. By rotating the cover plate 2, the spraying mechanism 3 can perform cleaning at different angles according to the specific shape of the graphite boat 200 and the cleaning requirements. For example, when certain areas of the graphite boat 200 need to be cleaned in a focused manner, the angle of the spraying mechanism 3 can be adjusted by rotating the cover plate 2, allowing the spraying mechanism 3 to be more precisely aimed at these areas, thereby improving the targeting and efficiency of the cleaning. This flexibility not only helps to improve the cleaning quality but also adapts to graphite boats 200 of different sizes and shapes, enhancing the versatility of the cleaning tank 100.

[0058] Furthermore, the rotating mechanism 4 enhances the structural stability and service life of the cleaning tank 100. During the cleaning process, the impact of the water flow may affect the structure of the cover plate 2 and the tank body 1. The rotating mechanism 4 is designed to disperse the impact of the water flow, reduce concentrated stress on the connection points, thereby reducing the risk of wear and damage at the connection points and extending the service life of the cleaning tank 100.

[0059] The rotating mechanism 4 can take various forms or structures. For example, the rotating mechanism 4 may include a physical shaft connected between the groove 1 and the cover plate 2, allowing the groove 1 and the cover plate 2 to rotate relative to each other, or a virtual shaft that enables relative rotation of the groove 1 and the cover plate 2 through a specific structure such as a hinge. The rotating mechanism 4 may also include various manual or automatic drive structures that can apply a certain force to the shaft, the groove 1, or the cover plate 2, allowing the groove 1 and the cover plate 2 to rotate relative to each other under the constraint of the shaft. In some embodiments, the drive structure in the rotating mechanism 4 can drive the shaft to rotate, thereby driving the cover plate 2 to rotate relative to the groove 1; while in other embodiments, the drive structure of the rotating mechanism 4 can directly apply a force to the groove 1 or the cover plate 2, thereby pushing the cover plate 2 to rotate relative to the groove 1.

[0060] Please see Figure 7 , Figure 7 yes Figure 6 The enlarged schematic diagram at point A shows that, in some embodiments, the rotating mechanism 4 includes: a drive shaft 41, which passes through the groove 1 and extends along the first direction X; a drive gear 42, which is sleeved on the drive shaft 41 and configured to rotate with the drive shaft 41; a driven gear 43, which meshes with the drive gear 42 and is configured to rotate with the drive gear 42; and a driven shaft 44, which passes through the cover plate 2 and extends along the first direction X with the drive shaft 41, and is configured to rotate with the driven gear 43 to drive the cover plate 2 to rotate.

[0061] Specifically, after the drive shaft 41 rotates, the drive gear 42 rotates with the drive shaft 41. Then, the drive gear 42 meshes with the driven gear 43, causing the driven gear 43 to rotate, thereby driving the driven shaft 44 that passes through the driven gear 43. The rotation of the driven shaft 44 causes the cover plate 2 to rotate relative to the groove 1.

[0062] It is understandable that gear transmission can ensure the accuracy and synchronization of the rotation process, making the opening and closing of cover plate 2 smoother and more stable, avoiding problems such as jamming or excessive rotation.

[0063] Meanwhile, the adjustable gear ratio facilitates the control of the rotation angle of the cover plate 2. By appropriately designing the gear ratio of the driving gear 42 and the driven gear 43, precise control of different angles can be achieved to meet the requirements of different cleaning processes for the spray angle. For example, when a specific area of ​​the graphite boat 200 needs to be cleaned, the rotation angle of the cover plate 2 can be precisely adjusted so that the spray mechanism 3 is aimed at the target area for concentrated cleaning, thereby improving cleaning efficiency and effectiveness.

[0064] Furthermore, gear transmission offers high efficiency and a long service life. The meshing transmission between the driving gear 42 and the driven gear 43 can withstand large torques, ensuring good performance even under frequent opening and closing operations. At the same time, the standardized design of the gears facilitates replacement and maintenance, reducing maintenance costs and downtime for the cleaning tank 100.

[0065] In some embodiments, the cleaning tank 100 further includes a rotating handle (not shown), which is connected to the drive shaft 41 and configured to drive the drive shaft 41 to rotate. The rotating handle, connected to the drive shaft 41, allows the drive shaft 41 to rotate directly by manual rotation. When an operator holds the rotating handle and applies rotational force, the drive shaft 41 rotates, thereby driving the drive gear 42, which is fitted onto the drive shaft 41, to rotate. Since the drive gear 42 meshes with the driven gear 43, the driven gear 43 also rotates, thereby driving the driven shaft 44 to rotate. Ultimately, the rotation of the driven shaft 44 causes the cover plate 2 to rotate around its axis, realizing the opening or closing action of the cover plate 2.

[0066] Understandably, turning the handle allows operators to easily control the opening and closing of the cover 2 without relying on complex drive equipment or electrical systems, simplifying the operation of the cover 2 and improving its convenience and flexibility. By turning the handle, operators can precisely control the rotation angle of the cover 2 according to actual needs, ensuring that the spray mechanism 3 is in the optimal cleaning position.

[0067] This manual control method, which controls the opening and closing of the cover plate 2 by turning the handle, not only reduces the operating cost of the cleaning tank 100, but also enhances the reliability and ease of maintenance of the cleaning tank 100. It also provides greater flexibility in the use of the cleaning tank 100, enabling it to adapt to different cleaning processes and operating environments.

[0068] Please see Figure 2 In some embodiments, the cleaning tank 100 further includes a drive (not shown in the figure), which is connected to the rotating mechanism 4 and is configured to drive the cover plate 2 to rotate relative to the tank body 1.

[0069] Optionally, the driving component can be a device capable of providing rotational power, such as a motor, cylinder, or hydraulic cylinder. When the driving component is working, it outputs linear or rotational torque, driving the cover plate 2 to rotate or the drive shaft 41 to rotate. Taking a motor as an example, in one embodiment, the output shaft of the motor is connected to the drive shaft 41 via a coupling. After the motor starts, the rotation of the output shaft directly transmits power to the drive shaft 41, and then drives the driven shaft 44 to rotate through the meshing of the drive gear 42 and the driven gear 43, ultimately realizing the opening and closing action of the cover plate 2. In another embodiment, the output shaft of the motor can move forward or backward along its own axis, thereby lengthening or shortening. The output shaft of the motor can then be connected to the cover plate 2 or the groove 1, so that the extension or shortening of the motor output shaft causes it to rotate relative to its own shaft, realizing the opening and closing action of the cover plate 2.

[0070] Understandably, the drive unit increases the automation level of the cleaning tank 100 and improves work efficiency. The drive unit can achieve precise speed and angle control, ensuring that the cover plate 2 stops accurately at the required position, meeting the requirements of different cleaning processes.

[0071] In addition, the drive components enhance the adaptability of the cleaning tank 100, allowing for the selection of appropriate drive component types and specifications, such as motor speed and torque, to suit various cleaning tasks according to the production process.

[0072] In some embodiments, the cleaning tank 100 further includes a control unit electrically connected to a drive member, the control unit being configured to control the rotation state of the drive member to adjust the rotation angle of the cover plate 2 relative to the tank body 1.

[0073] It is understandable that the control unit can adjust the rotation angle of the cover plate 2 relative to the tank 1 according to preset requirements. Specifically, the control unit sends corresponding control signals to the drive component according to a predetermined program or real-time operation instructions. The drive component adjusts the rotation speed, direction and angle accordingly, thereby driving the cover plate 2 to achieve precise opening and closing.

[0074] The control unit optimizes the automation level of the cleaning tank 100, improving the stability and reliability of the cleaning process. Simultaneously, by precisely controlling the opening and closing angle of the cover plate 2, it better meets the spray angle requirements of different cleaning processes, thereby improving the cleaning effect.

[0075] Optionally, the cleaning tank 100 may also be equipped with detection elements such as angle detection sensors and liquid level detection sensors. The control unit can dynamically adjust the rotation angle of the cover plate 2 and the cleaning process based on the real-time information fed back by the sensors, such as the position of the cover plate 2, the liquid level of the cleaning fluid, and the cleaning status of the graphite boat 200, to ensure the efficient operation of the cleaning process.

[0076] Please see Figure 2In some embodiments, the spraying mechanism 3 includes: a plurality of spray pipes 31, the length of which extends along a first direction X, the plurality of spray pipes 31 being spaced apart along a second direction Y, the first direction X being the length direction of the cleaning tank 100, and the second direction Y intersecting the first direction X; a plurality of spray heads 32, each spray pipe 31 being provided with a plurality of spray heads 32, the plurality of spray heads 32 on each spray pipe 31 being spaced apart along the first direction X, each spray head 32 being connected to each spray pipe 31, and the spray heads 32 being configured to spray the cleaning liquid in each spray pipe 31 into the receiving cavity.

[0077] The spraying mechanism 3 includes multiple spray pipes 31 and spray heads 32. The length of the spray pipes 31 extends along the first direction X, and the multiple spray pipes 31 are arranged at intervals in the second direction Y, ensuring that the spray pipes 31 can cover the entire working area of ​​the cleaning tank 100, providing a basis for the comprehensive cleaning of the graphite boat 200.

[0078] Optionally, the spray pipe 31 and the cover plate 2 can be detachably connected by bolts, quick connectors, or clamps. This application embodiment does not limit this.

[0079] Each spray pipe 31 is equipped with multiple spray heads 32, which are spaced apart along the first direction X. Each spray head 32 is connected to a corresponding spray pipe 31, allowing the cleaning fluid to be delivered from the spray pipe 31 to each spray head 32 and finally sprayed into the receiving cavity of the cleaning tank 100. The spray heads 32 ensure that the cleaning fluid is evenly distributed across the entire surface of the graphite boat 200, thereby improving the cleaning coverage and efficiency.

[0080] Furthermore, the spray head 32 is detachably mounted on the spray pipe 31, which facilitates the replacement or maintenance of the spray head 32 according to different cleaning needs, ensuring the efficient operation of the spray system.

[0081] Optionally, the spray head 32 and the spray pipe 31 can be detachably connected by bolts. The spray head 32 is provided with external threads, and the spray pipe 31 is provided with multiple mounting holes corresponding to multiple spray heads 32. The inner wall of the mounting hole is provided with internal threads, and the spray head 32 is connected to the mounting hole through the external threads and internal threads.

[0082] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the structure of the high-pressure spray head 32 provided in the embodiment of this application. Figure 9This is a schematic diagram of the structure of the covering spray head 32 provided in this application embodiment. Optionally, the spray head 32 can be of various types, such as high-pressure penetration type, fan-shaped covering type, or atomizing rinsing type, to adapt to different cleaning needs. The high-pressure spray head 32 adopts a small-hole design, which provides high impact force and fast flow rate of the cleaning fluid, focusing on deep penetration and local high pressure. The high-pressure spray head 32 can generate a strong water flow impact force, effectively removing stubborn stains and particles from the surface of the graphite boat 200, and is suitable for areas with high requirements for cleaning effect. The covering spray head 32 adopts a multi-hole design, with outlets distributed in a ring or fan shape, focusing on wide and uniform coverage. The covering spray head 32 ensures that the cleaning fluid can be evenly distributed on the entire surface of the graphite boat 200 through a wide spray coverage, improving the cleaning coverage and overall effect.

[0083] It is understandable that by selecting the appropriate type of spray head 32 and optimizing the arrangement spacing, the graphite boat 200 can be cleaned in all directions without dead angles, effectively removing surface impurities and meeting the high cleanliness requirements of the graphite boat 200 in the solar cell manufacturing process.

[0084] Please see Figure 5 and Figure 6 In some embodiments, when the cover plate 2 rotates relative to the tank 1, the angle between the cover plate 2 and the horizontal plane ranges from 0° to 90°; wherein, when the cover plate 2 is at 0° relative to the horizontal plane, the tank 1 is in a closed state.

[0085] When cover plate 2 rotates relative to the horizontal plane, the rotation angle range of cover plate 2 is set from 0° to 90°. When cover plate 2 rotates to 0° with the horizontal plane, cover plate 2 fits tightly with tank 1, forming a closed receiving cavity. At this time, tank 1 is in the closed state, ensuring that the cleaning fluid will not leak and preventing external impurities from entering, providing a stable environment for cleaning graphite boat 200. As cover plate 2 rotates upward from 0°, the angle between cover plate 2 and the horizontal plane gradually increases until it reaches 90°, at which point cover plate 2 is in the fully open state, facilitating the placement and removal of graphite boat 200.

[0086] During the rotation of the cover plate 2, the spray mechanism 3 rotates together with the cover plate 2, thereby adjusting the spray angle as needed to achieve the best cleaning effect. This allows the cleaning tank 100 to operate efficiently at different stages of operation, meeting the sealing requirements during cleaning and facilitating the loading and unloading of the graphite boat 200.

[0087] Please see Figure 5 and Figure 6In some embodiments, the cover plate 2 includes a first cover plate 21 and a second cover plate 22. The first cover plate 21 and the second cover plate 22 are rotatably disposed on opposite sides of the opening. When the angle of the first cover plate 21 and the second cover plate 22 relative to the horizontal plane is 0°, the tank 1 is in a closed state. Multiple spray pipes 31 are provided on the side of the first cover plate 21 and the second cover plate 22 facing the tank 1.

[0088] The cover 2 includes a first cover 21 and a second cover 22, which are rotatably mounted on opposite sides of the opening of the cleaning tank 100. This design allows the first cover 21 and the second cover 22 to rotate independently, providing greater operational flexibility for opening and closing the cover 2.

[0089] When the angles of the first cover plate 21 and the second cover plate 22 relative to the horizontal plane are both 0°, the first cover plate 21 and the second cover plate 22 are fitted together to form a complete closed structure, keeping the tank 1 in a closed state. At this time, a sealed containment cavity is formed inside the cleaning tank 100, ensuring that the cleaning fluid will not leak and preventing external impurities from entering, providing a stable environment for the cleaning of the graphite boat 200. The first cover plate 21 and the second cover plate 22 can be rotated upwards to form a certain angle, facilitating the loading and unloading of the graphite boat 200, and the opening and closing angle of the cover plate 2 can be adjusted according to actual cleaning needs to improve cleaning efficiency.

[0090] It is understood that the number of spray pipes 31 set on the first cover plate 21 can be equal to the number of spray pipes 31 set on the second cover plate 22, and the distance between each spray pipe 31 is equal, so as to ensure the uniformity of the spraying of the graphite boat 200 by the cleaning tank 100.
