Description

Technical Field

[0001] This invention relates to the field of photovoltaic glass production technology, and in particular to a debris cleaning device for a whole photovoltaic glass panel. Background Technology

[0002] Annealing is a common process in photovoltaic glass production. When photovoltaic glass is annealed in an annealing furnace, some oxides or dust particles fall from the furnace top onto the surface of the glass (commonly known as the air surface). The longer the annealing furnace is used, the more oxides or dust particles fall from the furnace top onto the air surface of the glass. If these impurities are not cleaned in time, they will block the light when the glass passes through the defect inspection machine, affecting the detection of glass defects. When the amount of dust and impurities reaches a certain level, the inspection machine will reject the glass or malfunction, and a debris cleaning device will be used to process the photovoltaic glass.

[0003] In existing technology, float glass production lines are equipped with a blowing and dust removal device after the emergency drop of the glass at the annealing furnace outlet. This device blows dust and debris to both sides of the glass sheet to ensure that the effective area in the middle of the glass is not contaminated. This technology can play a certain cleaning role, but the cleaning effect is not good. When the glass passes through the inspection machine, many particles and debris can still be detected, affecting the quality of the glass sheet. At the same time, due to the lack of dust collection function or poor dust collection effect, a lot of dust and debris will be blown into the air in the emergency drop area and fall to the ground, seriously affecting the production environment in that area.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a debris cleaning device for photovoltaic glass panels. The debris cleaning device for photovoltaic glass panels includes a debris removal component 1 and a belt conveyor 2. By setting the debris removal component 1, gas can be sprayed out and gas convection can be used to achieve the purpose of blowing away dust and removing debris in the debris removal working state. At the same time, it can transmit and filter and collect impurities, which provides a guarantee for the stable operation of the inspection machine. While ensuring stable production, it ensures product quality and environmental pollution in the workshop, and realizes clean production.

[0033] Specifically, the impurity removal component 1 includes two airflow transmission shells 11. A centrifugal fan 113 is bolted to the top of each airflow transmission shell 11. A cleaning frame 12 is fixed between the two airflow transmission shells 11. Two first air chambers 121 and a single second air chamber 122 are respectively opened within the cleaning frame 12. Air supply components 13 are provided on both sides of the cleaning frame 12 for introducing gas. Each air supply component 13 includes a transmission cylinder 131. A ventilation ring 132 is fixed to one end of the transmission cylinder 131. A rotating sleeve 133 is rotatably connected to the ventilation ring 132. A turbine blade 1332 is fixed inside the cleaning frame 12. A return air pipe 14 is fixed at the center of the cleaning frame 12 for drawing out gas. A through groove 141 is opened at the bottom of the return air pipe 14. An auxiliary air component 16 is installed inside the return air pipe 14. The auxiliary air component 16 includes a rotating cylinder 161 located inside the return air pipe 14. An air jet head 162 is rotatably connected to the outer ring of the rotating cylinder 161. An adjusting component 15 is installed at the center of the cleaning frame 12. The adjusting component 15 includes a fixed plate 155 fixed inside the cleaning frame 12. A movable plate 156 is rotatably connected to the bottom of the fixed plate 155.

[0034] Specifically, belt conveyor 2 is located at the bottom of cleaning frame 12 and is used to smoothly transport photovoltaic glass panels.

[0035] The belt conveyor 2 consists of a conveyor belt, rollers, idlers, a drive unit, a tensioning device, and a frame. Its working principle is that the drive unit drives the drive rollers to rotate, and the friction between the rollers and the conveyor belt drives the conveyor belt to move continuously in a cycle. The photovoltaic glass is placed on the conveyor belt and moves synchronously with it. The conveying direction is adjusted by the redirecting rollers, and finally the material is transferred from the starting point to the end point. It has the characteristics of large conveying capacity, long conveying distance, and continuous uninterrupted operation. It also has a simple structure, stable operation, low maintenance cost, and relatively low energy consumption. It is easy to realize automated control and production line integration. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0036] Example 2, refer to Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, two airflow transmission shells 11 are symmetrically arranged on both sides of the belt conveyor 2. Each airflow transmission shell 11 has a return air chamber 111 and an air inlet chamber 112, with the air inlet chamber 112 located inside the return air chamber 111. The air inlet end of the centrifugal fan 113 extends into the air inlet chamber 112. An auxiliary pipe 1131 is fixed to the air outlet end of the centrifugal fan 113. The end of the auxiliary pipe 1131 away from the centrifugal fan 113 extends into the return air chamber 111. A filter cartridge 114 is fixed inside the air inlet chamber 112. Both ends of the return air pipe 14 pass through the filter cartridge 114 to filter the transmitted gas. The air inlet end of the gas delivery component 13 extends into the return air chamber 111.

[0038] The return air chamber 111 and the intake air chamber 112 separate the internal space of the airflow transmission shell 11, forming two gas flow spaces that do not interfere with each other.

[0039] When the centrifugal fan 113 is working, the gas flows upward from the inlet chamber 112 and is discharged into the return chamber 111 through the auxiliary pipe 1131. With the cooperation of the gas delivery component 13 and the return pipe 14, the gas can flow through the return pipe 14, the filter cartridge 114, the inlet chamber 112, the auxiliary pipe 1131, the return chamber 111 and the gas delivery component 13 to form a complete circulating airflow transmission line, which can effectively remove impurities from the photovoltaic glass on the belt conveyor 2.

[0040] Specifically, a dust inlet 123 is provided at the center of the bottom of the cleaning frame 12 to meet the airflow transmission requirements containing dust.

[0041] The gas discharged through the gas supply component 13 will enter the first gas chamber 121. The air flow velocity in the two first gas chambers 121 is different. Under the guidance of the regulating component 15, the two airflows converge at the impurity inlet 123. Dust and impurities are blown away from the photovoltaic glass panel and enter the middle second gas chamber 122 to complete the cleaning operation.

[0042] Specifically, the outer ring of the ventilation ring 132 has a first air hole 1321, and the outer ring of the rotating sleeve 133 has a second air hole 1331 that cooperates with the first air hole 1321. The number of the first air hole 1321 and the second air hole 1331 are the same and the same size. The inner diameter of the first air hole 1321 is larger the farther away from the air inlet end of the transmission cylinder 131, in order to meet the remote exhaust requirements. The connection between the rotating sleeve 133 and the ventilation ring 132 is sealed.

[0043] An auxiliary frame 1333 is fixed to the inner wall of the rotating sleeve 133, and the turbine blade 1332 is screwed onto the auxiliary frame 1333. The rotating sleeve 133, the turbine blade 1332 and the auxiliary frame 1333 are all made of polytetrafluoroethylene, which has the advantages of low friction coefficient, wear resistance, high temperature resistance and light weight.

[0044] With the turbine blade 1332 in place, the airflow transmitted through the transmission cylinder 131 and the ventilation ring 132 will cause the rotating sleeve 133 to rotate, thereby causing the first air hole 1321 and the second air hole 1331 to continuously overlap or misalign.

[0045] Specifically, the center of the return gas pipe 14 is designed to be sealed, forming two separate delivery lines.

[0046] In practical applications, the airflow entering the second air chamber 122, mixed with dust and impurities, will enter the return air pipe 14 through the through groove 141 and be transported into the filter cartridge 114 for interception and filtration.

[0047] Specifically, the auxiliary gas component 16 also includes two stabilizing blocks 163 fixed to the inner wall of the return gas pipe 14, and the rotating cylinder 161 is fixed between the two stabilizing blocks 163. The outer ring of the rotating cylinder 161 is provided with a first air groove 1611.

[0048] Specifically, the connection between the jet head 162 and the rotating drum 161 is sealed. A transmission cavity 1622 is provided inside the jet head 162. A second air groove 1621 that cooperates with the first air groove 1611 is provided inside the transmission cavity 1622. A jet hole 1624 is provided at the outer end of the jet head 162.

[0049] Specifically, a coil spring 1623 is fitted around the outer ring of the rotating drum 161. One end of the coil spring 1623 is fixed to the stabilizing block 163, and the other end of the coil spring 1623 is fixed to the jet head 162 to provide torque to the jet head 162.

[0050] Specifically, the jet head 162 is set at an angle, and one end of the rotating drum 161 is fixed with an air supply pipe 164. The other end of the air supply pipe 164 passes through the cleaning frame 12 and is connected to the external air pump.

[0051] The spring 1623 provides torque to the jet head 162, thereby maintaining the jet head 162 in an inclined state without external force. At this time, the second air groove 1621 and the first air groove 1611 are misaligned. The gas transmitted through the air pipe 164 can be transmitted into the return air pipe 14 through the rotating drum 161, the first air groove 1611, the second air groove 1621, the transmission chamber 1622 and the jet hole 1624, providing auxiliary airflow power for gas transmission.

[0052] The gas can be evenly diffused into the return pipe 14 through the jet hole 1624, and since the jet head 162 is set at an angle, it can provide auxiliary airflow to facilitate the discharge of dust and impurities.

[0053] When the photovoltaic glass is large and the cleaning frame 12 has a large span, using only the centrifugal fan 113 may result in insufficient suction on the side away from the centrifugal fan 113. With the assistance of the auxiliary air component 16, an auxiliary airflow can be provided to accelerate the discharge of dust and impurities, which is more in line with actual usage needs.

[0054] Specifically, the adjusting component 15 also includes two screw sleeves 151 embedded in the top of the cleaning frame 12. The screw sleeves 151 are internally threaded with screw rods 152. The bottom of the screw rods 152 is rotatably connected to connecting rods 157. The bottom of the connecting rods 157 is connected to a first connecting frame 153 via a pivot. The bottom of the first connecting frame 153 is connected to a second connecting frame 154 via a pivot. The bottom end of the second connecting frame 154 is fixed to the movable plate 156.

[0055] The fixed plate 155 is fixed to the inner wall of the cleaning frame 12, while the movable plate 156 slides in contact with the inner wall of the cleaning frame 12 and is sealed.

[0056] As the screw 152 gradually moves downward, the movable plate 156 can rotate around the fixed plate 155 under the connection of the connecting rod 157, the first connecting frame 153 and the second connecting frame 154. This is used to adjust the tilt angle of the movable plate 156, change the distance between the movable plate 156 and the inner wall of the cleaning frame 12, and adjust the gas flow space transmitted through the first air chamber 121.

[0057] Example 3, referring to Figures 2-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0058] Specifically, there are several transmission cylinders 131, among which the transmission cylinder 131 located on the cleaning frame 12 is fixedly installed, and the transmission cylinder 131 located inside the cleaning frame 12 is fixed to the inner wall of the cleaning frame 12 by a support rod.

[0059] A backflush valve 115 is fixed on the airflow transmission housing 11, and an auxiliary plate 116 is fixed to the bottom inner side of the airflow transmission housing 11 with screws.

[0060] The connection between the auxiliary plate 116 and the airflow transmission shell 11 is sealed. With the backflush valve 115, the filter cartridge 114 can be pulsed backflushed to prevent blockage, in conjunction with the airflow. In actual operation, the auxiliary plate 116 can be removed, which makes it convenient for the operator to remove the filter cartridge 114 and clean the collected dust and impurities.

[0061] As shown in the attached diagram of the instruction manual. Figure 8 As shown, taking two adjacent ventilation rings 132 as an example, when the first air hole 1321 and the second air hole 1331 on the right ventilation ring 132 coincide, the first air hole 1321 and the second air hole 1331 on the left ventilation ring 132 are misaligned. With this design, when gas is transmitted through the transmission cylinder 131, after being discharged through the smaller-sized first air hole 1321 and second air hole 1331, the gas flow velocity entering the rotating sleeve 133 is relatively high. With the cooperation of the turbine blades 1332, the rotating sleeve 133 accelerates its rotation, reducing the exhaust time of the smaller-sized first air hole 1321. When the gas is discharged through the large-sized first air hole 1321 and second air hole 1331, the gas flow rate into the rotating sleeve 133 is relatively low. The rotating sleeve 133 decelerates and rotates, increasing the exhaust time of the large-sized first air hole 1321. According to this design, the first air hole 1321, which is closer to the air inlet end of the transmission cylinder 131, exhausts at high speed and has a short exhaust time, while the first air hole 1321, which is farther from the air inlet end of the transmission cylinder 131, exhausts at low speed and has a longer exhaust time. This allows the gas to be evenly distributed in the first air chamber 121, which can uniformly spray and clean the top of the photovoltaic glass.

[0062] In practical applications, the gas supply pipe 164 is equipped with a one-way valve, which allows external gas to safely enter the rotating drum 161 in one direction through the gas supply pipe 164.

[0063] A handwheel is fixed to the top of the screw 152, which is used to facilitate the operator to drive the screw 152 to rotate, and then cooperate with the screw sleeve 151 to adjust the height of the bottom end of the screw 152.

[0064] In practical applications, for example, see the attached diagram in the instruction manual. Figure 6 As shown, when the photovoltaic glass is transported from left to right, the first air chamber 121 on the left is called the "forward blowing chamber" and the first air chamber 121 on the right is called the "reverse blowing chamber". The right screw sleeve 151 needs to be driven to rotate in the opposite direction in advance, so that the movable plate 156 gradually rotates upward. The air outlet of the reverse blowing chamber is wide and the air volume is large. The left screw sleeve 151 is driven to rotate in the forward direction, so that the movable plate 156 gradually rotates downward. The air outlet of the forward blowing chamber is narrow and the air volume is relatively small. This design is to prevent dust particles and debris from being blown away from the debris inlet 123 by the reverse blowing airflow, to prevent dust particles and debris from escaping and reduce the blowing and suction cleaning effect.

[0065] In practical applications, several cleaning components 1 can be installed on the outside of the belt conveyor 2 to form a multi-station cleaning system and ensure the cleaning effect on the photovoltaic glass panel.

[0066] In practical applications, the outlet end of the centrifugal fan 113 can be equipped with a discharge needle. In the working state, it not only provides airflow, but also ionizes the air into positive and negative ions through high-voltage corona discharge. This is used to eliminate static electricity on the photovoltaic glass and prevent static electricity from affecting the cleaning of small debris.

[0067] In use, with the belt conveyor 2 in operation, the photovoltaic glass is transported from left to right, and the centrifugal fan 113 is controlled to work. When the photovoltaic glass passes the cleaning frame 12, it is blown by the air convection through the two first air chambers 121, causing the dust and impurities on the top of the photovoltaic glass to be lifted. The dust and impurities enter the second air chamber 122 with the airflow, and are filtered by the filter cartridge 114 through the through groove 141 and the return air pipe 14. The clean air then enters the centrifugal fan 113, and so on, to complete the cyclic cleaning and impurity removal process.

[0068] Depending on the transmission direction of the photovoltaic glass panel, the two movable plates need to be pre-adjusted at a 156° tilt angle to ensure that a counter-flowing airflow is formed to lift up dust and impurities.

[0069] When the gas supply component 13 supplies gas, the rotating sleeve 133 can rotate continuously, causing the first air hole 1321 to repeatedly misalign or align with the second air hole 1331, thereby making the gas evenly distributed in the first air chamber 121, and finally evenly spraying and cleaning the photovoltaic glass panel.

[0070] Dust and impurities stirred up by the airflow enter the return air pipe 14. Due to the operation of the centrifugal fan 113 or other factors in the system, the gas transmission speed changes. When the air velocity entering the through slot 141 is low, there is no airflow to support the jet head 162. Under the action of the coil spring 1623, the jet head 162 rotates downward around the rotating drum 161. The first air slot 1611 and the second air slot 1621 gradually overlap. Under the action of the external air pump, the gas is transmitted through the air supply pipe 164, the rotating drum 161, the first air slot 1611, the second air slot 1621, the transmission chamber 1622 and the jet hole 1624 to form an upward-sloping auxiliary airflow, which accelerates the discharge of dust and impurities and better meets the actual use requirements.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
