Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module cleaning technology, and in particular to a cleaning device for retired photovoltaic modules. Background Technology

[0002] Photovoltaic modules, commonly known as solar panels or solar modules, are the core component of solar power generation systems. Their function is to directly convert sunlight into direct current (DC) electricity. In recent years, with the rapid development of the photovoltaic industry, a large number of early-installed photovoltaic modules are about to enter their retirement period. The recycling and disposal of retired photovoltaic modules is a key link in achieving resource recycling and environmental protection.

[0003] However, during transportation, storage, and long-term use, retired photovoltaic modules often accumulate impurities such as dust, dirt, oil, and encapsulant residue on their surfaces. If these impurities are not cleaned before being dismantled, it will not only affect the operational stability and dismantling efficiency of subsequent equipment (such as junction box removal, frame removal, and glass removal devices), but may also cause abnormal wear and blockage of mechanical parts. At the same time, the presence of surface impurities will reduce the purity of subsequent material sorting and recycling, increasing the risk of impurity contamination, thereby affecting the economic viability and reuse value of resource recycling.

[0004] Therefore, setting up a reliable cleaning process before retired photovoltaic modules enter the dismantling process is of great significance for ensuring the stable operation of the entire recycling production line and improving the resource recovery rate. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for retired photovoltaic modules, so as to solve the cleaning problem in the pretreatment of retired photovoltaic modules in the prior art.

[0006] The technical solution of this utility model is: a cleaning device for retired photovoltaic modules, comprising: a frame; A conveying platform, mounted on the frame, is used to convey photovoltaic modules along a predetermined path; The first cleaning zone is located on the conveying path of the conveying platform and is used for the initial cleaning of photovoltaic modules; The physical cleaning area is set on the conveying path of the conveying platform and is located downstream of the first cleaning area. It removes the adhering substances on the surface of the photovoltaic module through physical friction. The second cleaning zone is located on the conveying path of the conveying platform and downstream of the physical cleaning zone, and is used to clean the photovoltaic modules again. The drying zone is located on the conveying path of the conveying platform and downstream of the second cleaning zone, and is used to dry the cleaned photovoltaic modules.

[0007] Preferably, the first cleaning zone includes an upper spray assembly disposed above the conveying platform and a lower spray assembly disposed below the conveying platform. The spraying directions of the upper spray assembly and the lower spray assembly are opposite to each other to flush the upper and lower surfaces of the photovoltaic module.

[0008] Preferably, the first cleaning area is also integrated with a negative pressure mist suction system. The negative pressure mist suction system includes an air suction device located above the conveying platform and a water collection tank located below the conveying platform. The air suction device is used to collect water mist generated during the cleaning process, and the water collection tank is used to collect wastewater after cleaning.

[0009] Preferably, the structure of the second cleaning zone is the same as that of the first cleaning zone.

[0010] Preferably, the air intake device is connected to an exhaust system, which is used to exhaust the inhaled water vapor and impurities to the outside of the device or to a post-treatment system.

[0011] Preferably, the water collection tank is connected to a water circulation filtration system, which includes a filtration device and a circulation pump for filtering the sewage in the water collection tank and pumping it to the spray components of the first cleaning area and the second cleaning area.

[0012] Preferably, the physical cleaning area is a roller brush cleaning mechanism, which includes at least one rotatable roller brush. The bristles of the roller brush contact the surface of the photovoltaic module on the conveying platform and remove the surface deposits by friction.

[0013] Preferably, the drying zone includes a lower drying device disposed below the conveyor platform and an upper drying device disposed above the conveyor platform.

[0014] Preferably, the frame includes two spaced-apart support platforms and a support frame between them. Each support platform is equipped with a material conveying component, and the support frame supports the conveying platform and the various functional areas distributed along the conveying path.

[0015] Preferably, the first cleaning zone, the physical cleaning zone, the second cleaning zone, and the drying zone are all covered by a closed cavity.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: by setting up a first cleaning zone, a physical cleaning zone, a second cleaning zone, and a drying zone, a complete cleaning system is formed. The first cleaning zone uses high-pressure flushing to efficiently remove loose attachments such as dirt and gravel; the physical cleaning zone uses the physical friction of roller brushes to powerfully peel off stubborn adhesive film residues, oil stains, etc.; the second cleaning zone performs a fine wash again to thoroughly rinse away the small residues peeled off by physical cleaning, and finally dries the surface, achieving comprehensive removal of dirt from the surface of retired photovoltaic modules. This effectively avoids problems such as wear and blockage of subsequent dismantling equipment and reduced sorting accuracy caused by impurities, thereby improving the operating efficiency of the entire recycling production line and the recycling value of the final material.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1 to 4 As shown, a cleaning device for decommissioned photovoltaic modules includes a frame, which serves as the supporting foundation for the entire device.

[0019] The conveyor platform 6, mounted on the frame, is used to transport photovoltaic modules along a predetermined path, smoothly and continuously delivering the photovoltaic modules to be cleaned through each processing station.

[0020] The first cleaning zone 1 is set on the conveying path of the conveying platform 6 and is located at the front end of the conveying path. It is used to perform preliminary cleaning of photovoltaic modules and remove most of the loose attachments on the surface of photovoltaic modules, such as mud and gravel.

[0021] The physical cleaning zone is set on the conveying path of the conveying platform 6 and is located downstream of the first cleaning zone 1. It removes the adhering substances on the surface of the photovoltaic module through physical friction.

[0022] The second cleaning zone 3 is located on the conveying path of the conveying platform 6 and downstream of the physical cleaning zone, and is used to clean the photovoltaic modules again.

[0023] Drying zone 4 is located on the conveying path of conveying platform 6 and downstream of second cleaning zone 3, and is used to dry the cleaned photovoltaic modules.

[0024] like Figure 3 As shown, the first cleaning zone 1 includes an upper spray assembly 11 disposed above the conveying platform 6 and a lower spray assembly 12 disposed below the conveying platform 6. Both the upper spray assembly 11 and the lower spray assembly 12 are equipped with multiple sets of high-pressure nozzles, and the spraying directions of the upper spray assembly 11 and the lower spray assembly 12 are opposite to each other, so as to flush and rinse the upper and lower surfaces of the photovoltaic module, thereby cleaning the upper and lower surfaces of the photovoltaic module thoroughly and effectively.

[0025] The first cleaning zone 1 is also equipped with a negative pressure mist suction system. The negative pressure mist suction system includes an air suction device 101 located above the conveying platform 6 and a water collection tank 102 located below the conveying platform 6. The air suction device 101 is used to collect water mist generated during the cleaning process, and the water collection tank 102 is used to collect wastewater after cleaning.

[0026] The structure of the second cleaning zone 3 is the same as that of the first cleaning zone 1, including an upper spray assembly 11, a lower spray assembly 12, an air suction device 101, and a water collection tank 102. Its function is to rinse away the fine residues that have been peeled off from the surface of the module after being cleaned by the roller brush 2, and to perform a secondary fine cleaning of the photovoltaic module to further improve its surface cleanliness.

[0027] The suction device 101 is connected to an exhaust system 103, which is used to exhaust the sucked-in water vapor and impurities to the outside of the equipment or to the post-treatment system. Since the first cleaning zone 1 uses high-pressure spraying, a large amount of water mist will be generated. The suction device 101 is connected to the exhaust system 103 through a pipe. When working, it generates negative pressure, which can quickly suck in the water vapor and volatile organic compounds in the cleaning zone and exhaust them to the post-treatment system (such as an exhaust gas treatment device) outside the equipment. This effectively improves the workshop working environment and prevents water vapor from corroding the electrical components of the equipment.

[0028] The water collection tank 102 is connected to a water circulation filtration system, which includes a filter device and a circulation pump. The wastewater and large particles washed down from the first cleaning zone 1 and the second cleaning zone 3 will naturally fall into the water collection tank 102 below. After being filtered by the water circulation filtration system, the wastewater is pumped to the spray components of the first cleaning zone 1 and the second cleaning zone 3, thereby recycling water resources.

[0029] The physical cleaning area is a roller brush cleaning mechanism, which includes at least one rotatable roller brush 2. The bristles of the roller brush 2 contact the surface of the photovoltaic module on the conveying platform 6. Using physical friction, it removes impurities that are still stubbornly attached to the surface of the module after the initial rinsing, such as dried bird droppings, film residue, oil stains and other attachments.

[0030] like Figure 4 As shown, the drying zone 4 includes a lower drying device 41 located below the conveyor platform 6 and an upper drying device 42 located above the conveyor platform 6. Heated airflow is used to uniformly dry the surface of the photovoltaic modules as they move slowly forward with the conveyor platform 6, achieving drying while moving. The drying zone 4 can be designed as a multi-stage drying system according to actual needs, such as designing multiple sets of upper drying devices 42 to achieve gradient drying of the photovoltaic module surface, ensuring both drying effect and photovoltaic module safety. This avoids the risk of localized overheating and cracking of the glass panels on the photovoltaic modules due to excessively high temperatures from a single drying device designed for comprehensive drying.

[0031] like Figure 1 As shown, the frame includes two spaced-apart support platforms 8 and a support frame 9 between them. Each support platform 8 is equipped with a material conveying component 5, and the support frame 9 carries the conveying platform 6 and the various functional areas distributed along its conveying path.

[0032] The first cleaning zone 1, the physical cleaning zone, the second cleaning zone 3, and the drying zone 4 are all enclosed by a closed cavity 7. The closed cavity 7 provides a sealed space for the entire workflow, effectively preventing water mist, water droplets, noise, and potentially harmful substances from spreading outwards during the cleaning process, thus protecting the workshop environment and the health of the operators.

[0033] Working principle: Decommissioned photovoltaic modules awaiting cleaning are placed on support platform 8 via upstream equipment or manually, and then transported to conveyor platform 6 by material conveying component 5 for continuous conveying. First, the modules enter the first cleaning zone 1, where upper spray component 11 and lower spray component 12 perform high-pressure flushing to remove most loose dirt; simultaneously, a negative pressure mist suction system collects water mist, and wastewater falls into collection tank 102. The modules then enter the physical cleaning zone, where roller brush 2 rolls and rubs the module surface to remove stubborn deposits. Next, they enter the second cleaning zone 3, where they are again flushed and sprayed to thoroughly wash away any residue removed by the roller brush 2, completing further cleaning. Finally, the modules enter the drying zone 4, where upper drying device 42 and lower drying device 41 blow hot air to completely dry their surface. The photovoltaic modules, having completed all cleaning and drying processes, are output from the other end of conveyor platform 6 and transported by material conveying component 5 to support platform 8 on the other side.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
