Description

Technical Field

[0001] This application relates to the field of solar cell technology, and more particularly to a pipe cleaning device. Background Technology

[0002] In the field of battery technology, particularly in the production of solar cells, boron diffusion is a key technology for passivated contact cells. It involves diffusing boron into silicon materials to form a PN junction. This process is typically carried out at high temperatures and involves the use of various gases, including a boron source gas and a protective atmosphere. The waste gases generated during boron diffusion need to be effectively treated in the exhaust pipes of the boron diffusion unit to prevent environmental pollution and ensure production safety. During boron diffusion, the boron source gas condenses in the exhaust pipes to form boron oxide crystals. These crystals can gradually accumulate and eventually clog the exhaust pipes, causing increased pressure, leaks, and even equipment malfunctions. This blockage not only affects production efficiency but can also lead to safety risks, as leaked harmful gases may be released into the working environment.

[0003] Therefore, the waste discharge pipeline cleaning device of the boron expansion unit plays a crucial role in this process. It is responsible for removing residues from the pipeline and maintaining unobstructed gas flow, thereby ensuring the continuity and efficiency of the process. Boron oxide crystallization blockage at the tail end of the boron expansion unit leads to abnormal leakage rates, resulting in long downtime for handling blockages and resuming operation, and consequently, low work efficiency.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

Unless otherwise stated, "a plurality of" means two or more.

[0031] In the field of solar cell manufacturing, boron diffusion is a key technology for passivated contact solar cells. It involves diffusing boron into silicon material to form a PN junction. A boron diffusion furnace is a commonly used process furnace. By controlling the atmosphere and temperature within the furnace, typically at high temperatures, and using various gases, including a boron source gas and a protective atmosphere, boron atoms can be uniformly diffused into the silicon wafer, thereby forming the desired P-type emitter. During the boron diffusion process, gases such as boron chloride introduced will generate boron oxide dust in the exhaust pipes after the process.

[0032] The waste discharge pipeline has two branch pipes, each equipped with a main extraction valve and a water washing extraction valve. The waste discharge pipeline has an inlet and an outlet, with the inlet connected to a waste discharge condenser. During the process, the outlet is connected to a vacuum pump. When the vacuum pump is evacuating, only the main extraction valve is opened. Boron oxide dust is drawn from the furnace tubes into the condenser for cooling before entering the waste discharge pipeline. It passes through a filter element on the waste discharge pipeline, below which is a filter cartridge. Smaller pieces of boron oxide dust are filtered into the cartridge, while larger pieces are transported to subsequent processes through the waste discharge pipeline. During the water washing process, only the water washing extraction valve is opened. The machine's own steam washes the furnace tubes. The reaction between the steam and the boron oxide dust causes crystallization, exacerbating pipeline blockage. A bypass valve is branched off from the main extraction valve, with its outlet connected to the acid discharge pipeline. This bypass valve is opened during leak detection, allowing flowing powder to enter the equipment. During these processes, boron oxide dust and crystals accumulate inside the pipe walls. The boron oxide crystals accumulated in the waste discharge pipes of the boron expansion unit need to be effectively treated to prevent environmental pollution and ensure production safety.

[0033] Although boron oxide exhibits good volatility at high temperatures, the decrease in temperature in cooled waste discharge pipes causes it to recrystallize, forming solid crystals. These crystals can accumulate inside the pipes, especially at the tail end of the boron diffusion furnace where the crystallization is more severe due to the large temperature gradient. These crystals may gradually accumulate and eventually clog the waste discharge pipes, causing increased pressure, leaks, and even equipment malfunctions. Such blockages not only affect production efficiency but also pose safety risks, as leaked harmful gases may be released into the working environment.

[0034] Therefore, cleaning the waste discharge pipeline is particularly important to remove residues and maintain unobstructed gas flow, thereby ensuring the continuity and efficiency of the process. However, cleaning requires disassembling and cleaning each branch of the pipeline individually. This repeated disassembly and reassembly after each process cycle can damage pipeline joints, leading to abnormal leak rates. This not only slows down the process of dealing with boron oxide blockages but also increases the time required to restore operation, resulting in low work efficiency and high spare parts costs.

[0035] Based on this, this application discloses a pipe cleaning device that can clean waste discharge pipes without having to disassemble and reassemble each section of the waste discharge pipe multiple times for cleaning. The device directly connects the two ends of the waste discharge pipe as a whole by a water pumping component and rinses it with hot water, reducing the disassembly and reassembly of the waste discharge pipe, reducing damage to pipe joints, and improving cleaning efficiency.

[0036] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0037] Please see Figures 1 to 3 , Figure 1 This is a first-view structural schematic diagram of the pipe cleaning device 100 disclosed in the embodiments of this application. Figure 2 This is a schematic diagram of the pipe cleaning device 100 disclosed in the embodiments of this application from a second perspective. Figure 3 This application discloses a pipe cleaning device 100 for cleaning the waste discharge pipe 8 of a boron expansion unit. The waste discharge pipe 8 includes a first port a, a second port b, and a third port c. The first port a is the inlet of the waste discharge pipe 8, the second port b is the outlet of the waste discharge pipe 8 connected to a vacuum pump, and the third port c is a bypass outlet connected to an acid discharge pipe. The pipe cleaning device 100 includes a water supply tank 1, a recovery water tank 2, and a pumping assembly 3. The water supply tank 1 is used to hold water for cleaning the waste discharge pipe 8, the recovery water tank 2 is used to recover the wastewater after cleaning the waste discharge pipe 8, and the pumping assembly 3 includes a water pump 311, a pumping pipe 31, a heater 32, a first water pipe 33, and a second water pipe 34. The first end of the pumping pipe 31 is connected to the water supply tank 1, and the second end of the pumping pipe 31 is connected to the heater 32. The first port a of the waste discharge pipe 8 is connected to the heater 32, the second port b is connected to the heater 32, the third port c is connected to the heater 34, the third port a is connected to the heater 32, the third port b is connected to the heater 34, the fourth port b is connected to the heater 35, the fifth port b is connected to the heater 36, the sixth port b is connected to the heater 37, the seventh port b is connected to the heater 38, the eighth port b is connected to the heater 39, the ninth port b is connected to the heater 30, the eleventh port b is connected to the heater 31, the eleventh port b is connected to the heater 32 ... The first end of water pipe 33 is detachably connected to the second pipe port b, and the first end of water pipe 34 is detachably connected to the third pipe port c. The second ends of both water pipes 33 and 34 are connected to the recovery water tank 2. A water pump 311 is installed on the water supply pipe 31 to draw water from the water supply tank 1 into the heater 32. The heated water then flows through the waste discharge pipe 8 and into the recovery water tank 2, thereby flushing away the boron oxide crystals in the waste discharge pipe 8 and reducing the leakage rate caused by blockage due to boron oxide crystals. Cleaning the pipe with hot water is more thorough, and the cleaning of the waste discharge pipe 8 can be completed by disassembling both ends of the entire pipe, without having to disassemble each section of the waste discharge pipe 8. This saves operation time, reduces damage to pipe joints, extends the service life of the pipe, and saves on spare parts costs.

[0038] Combination Figure 1 and Figure 3As an optional implementation, the pipe cleaning device 100 also includes a water inlet pipe 4. The first end of the water inlet pipe 4 is connected to the heater 32, and the second end of the water inlet pipe 4 is detachably connected to the first port a of the waste discharge pipe 8, allowing heated water to flow from the water inlet pipe 4 into the waste discharge pipe 8. In this way, hot water is introduced from the heater 32 into the waste discharge pipe 8 through the water inlet pipe 4, lengthening the hot water transport path and preventing the hot water entering the waste discharge pipe 8 from overheating and damaging the pipe. Furthermore, it ensures the flow rate of the water entering the waste discharge pipe 8, providing sufficient flow space for the hot water and preventing the waste discharge pipe 8 from being directly connected to the heater 32, thus ensuring thorough and complete cleaning of the connection between the waste discharge pipe 8 and the pipe cleaning device 100.

[0039] Combination Figure 1 and Figure 3 It is understandable that the first water pipe 33 and the second water pipe 34 can be connected to the recycling tank 2 separately, but the connection method is cumbersome. In some possible embodiments, the pipe cleaning device 100 also includes a drain pipe 5, with the second end of the first water pipe 33 connected to the first end of the drain pipe 5, and the second end of the second water pipe 34 connected to the first end of the drain pipe 5. The second end of the drain pipe 5 is connected to the recycling tank 2, so that the wastewater flowing through the first water pipe 33 and the second water pipe 34 flows into the drain pipe 5, and the wastewater flows into the recycling tank 2 through a single drain pipe 5. This simplifies the pipeline design, not only avoiding the cumbersome connection method of inserting the second ends of the first water pipe 33 and the second water pipe 34 into the recycling tank 2 together, but also reducing the damage caused by multiple disassemblies of the first and second pipelines when treating the wastewater in the recycling tank 2, as only the second end of the drain pipe 5 needs to be disassembled.

[0040] It should be noted that the first water pipe 33, the second water pipe 34 and the drain pipe 5 can be manufactured as a single piece, or they can be connected by a T-connector. This embodiment does not limit this.

[0041] Combination Figure 1 Optionally, the pumping assembly 3 also includes an outlet pipe 35, a diverter 36, and a distribution pipe 361. One end of the outlet pipe 35 is connected to the heater 32, and the other end is connected to the inlet of the diverter 36. The first end of the distribution pipe 361 and the first end of the inlet pipe 4 are respectively connected to the two outlets of the diverter 36, and the second end of the distribution pipe 361 is connected to the water supply tank 1, so that part of the hot water in the outlet pipe 35 is diverted back to the water supply tank 1 through the distribution pipe 361, and the other part of the hot water flows into the inlet pipe 4. The flow of hot water in the pipe will result in a large pressure inside the pipe. The diverter 36 diverts part of the hot water from the pipe, thereby achieving a pressure distribution effect and realizing the rational distribution of hot water. Part of the hot water is recycled to the circulating water tank, reducing heat loss, and the other part of the hot water is directly used for cleaning the waste pipe 8, improving the cleaning effect and optimizing energy utilization efficiency.

[0042] Combination Figure 1 As an optional implementation, the pipeline cleaning device 100 also includes a mobile trolley 6. The upper layer of the mobile trolley 6 is provided with an installation groove 61 for placing the water supply tank 1, the recovery water tank 2, and the heater 32. The mobile trolley 6 provides a stable placement platform for the circulating water tank, the recovery water tank 2, and the heater 32, improving the portability and flexibility of the pipeline cleaning device 100. This facilitates movement and operation at different work sites and makes it convenient to use in different work locations, thereby improving the ease of use and work efficiency of the pipeline cleaning device 100.

[0043] Combination Figure 1 In some embodiments, the pumping assembly 3 further includes a power strip 321, which is disposed on the outer wall of the mobile trolley 6 to provide power to the heater 32. The power strip 321 ensures a stable power supply to the heater 32. The power strip 321 is disposed on the side wall, while the water tank and pumping assembly 3 are both disposed inside the mobile trolley 6, which largely prevents water from leaking onto the power strip 321 and causing damage, thus improving operational safety and convenience.

[0044] Combination Figure 2 As an optional implementation, the bottom of the mobile trolley 6 is provided with a water receiving tray 62, which is located vertically below the mounting groove 61. The water receiving tray 62 can collect some of the liquid leaking from the water supply tank 1, the recovery tank 2, and the pumping assembly 3, while also facilitating the maintenance and cleaning of the equipment, thus improving the practicality and safety of the entire device.

[0045] Understandably, the water pump 311 is mounted on the water receiving tray 62, and the water pump pipe 31 passes through the water pump 311 on the water receiving tray 62 to the upper part of the mobile trolley 6 and is connected to the heater 32.

[0046] Combination Figure 1 In some possible implementations, the pipe cleaning device 100 also includes an adapter 7, through which the waste discharge pipe 8 is connected to the inlet pipe 4, the first water pipe 33, and the second water pipe 34. The adapter is typically simple in design, easy to install and maintain, and convenient to disassemble, enhancing the flexibility and adaptability of pipe connections, improving work efficiency, and providing flexible connection options for various standard pipe sizes.

[0047] Optionally, the adapter 7 can be a clamp, crimping fitting, or tower-type adapter, etc. The clamp connection connects the hose to an unthreaded pipe or equipment by using a clamp to firmly fix the hose to the adapter; the crimping connection uses a special crimping tool to press the metal fitting of the hose to the hose body to form a sealed connection.

[0048] As an optional implementation, adapter 7 is a tower-type adapter. Tower-type connections offer better structural stability, especially when subjected to lateral forces and bending moments. This connection method helps distribute the load, reduces stress concentration at individual connection points, thereby improving the safety of the entire piping system. The connection is more compact, ensuring the piping system's sealing, stability, and ease of maintenance, while reducing the space occupied, decreasing fluid flow resistance, and improving system efficiency.

[0049] The pipeline cleaning device 100 has many connecting pipes, and ordinary water pumps may not be able to provide sufficient water pressure to clean the waste discharge pipes. Optionally, the water pump 311 can be a booster pump to increase the water pressure to flush the waste discharge pipes 8. This increases the water pressure and accelerates the water flow rate. Based on centrifugal force and volume change, liquid pressurization is achieved, providing sufficient water pressure to ensure that the liquid can be delivered into the pipes, resulting in cleaner pipe cleaning.

[0050] Combination Figures 1 to 3 When washing the waste discharge pipe 8, open the water pump 311 and the valve 81 on the waste discharge pipe 8, and replace the filter cartridge on the waste discharge pipe 8 with the filter plug 82. The water in the water supply tank 1 enters the heater 32 from the water pump 31 and is heated into hot water. It flows into the water outlet pipe 35 and is partially diverted back to the water supply tank 1 by the diverter 36. The remaining hot water is used to clean the waste discharge pipe 8. It enters the waste discharge pipe 8 through the first pipe port a through the water inlet pipe 4, flows out from the second pipe port b and the third pipe port c, and finally flows into the recovery water tank 2 through the drain pipe 5, thus completing the cleaning of the waste discharge pipe 8.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
