Description

Technical Field

[0001] This utility model belongs to the technical field of dust collection equipment, specifically relating to a dust adsorption device for perovskite battery encapsulation. Background Technology

[0002] The purpose of perovskite solar cell encapsulation is to create a robust, highly airtight, and highly watertight sealed environment to isolate moisture and oxygen, and prevent physical scratches and chemical corrosion. During the encapsulation process, the perovskite film is extremely fragile; even micron- or nano-sized dust particles can cause encapsulation failure. Therefore, dust adsorption and removal operations are necessary to prevent suspended particulate matter and debris from the perovskite cell processing from falling onto the perovskite cell surface or encapsulating adhesive, which could cause wear or create gaps in the encapsulated perovskite cell, allowing moisture and oxygen to enter the cell. In the cleanroom for perovskite solar cell encapsulation, industrial vacuum cleaners are a common dust removal device used to adsorb dust from the workshop environment. Air is delivered into the clean encapsulation room through HEPA / ULPA filters in the dust collection bin to prevent secondary dust generation. This cleans the workshop floor and processing tables of settled dust and removes airborne dust around the encapsulation station, protecting the workpiece (such as the perovskite substrate) from contamination by operators and the surrounding environment.

[0003] In existing industrial vacuum cleaners, as vacuuming continues, dust accumulates on the filter media in the dust collection bin. Dust particles can clog the micropores of the filter media and the air delivery pipes, leading to poor airflow and reduced suction. Cleaning the filter media requires opening the dust collection bin lid, removing the filter media and emptying the dust, then reinstalling the filter media and finally closing the dust collection bin lid, which is a rather complicated process. Cleaning the pipes is also cumbersome, requiring disassembly. Furthermore, industrial vacuum cleaners lack pre-filtration of the dusty air entering the pipes and do not have a design that facilitates disassembly and cleaning, which needs improvement.

[0004] Existing industrial vacuum cleaners lack pre-filtration of dusty gases entering the duct and have duct connection designs that facilitate disassembly and cleaning. To address this, this application proposes a perovskite battery encapsulation dust adsorption device. Utility Model Content

[0005] The purpose of this invention is to provide a dust adsorption device for perovskite battery encapsulation, in order to solve the problem mentioned in the background art that industrial vacuum cleaners do not have a pipe connection design that pre-filters the dusty gas entering the pipe and facilitates disassembly and cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a perovskite battery encapsulation dust adsorption device, comprising a dust removal device for adsorbing dust around the perovskite battery encapsulation station, including a mobile trolley and a dust collection bin, an air supply pipe connected to the inside of the dust collection bin, a handheld rod connected to the inside, and a first suction head; further comprising a pre-filter for filtering dust particles in the conveying gas, including a split-connected connecting pipe head and a locking sleeve, a support mesh cylinder fixedly connected to the connecting pipe head, and a filter bag sleeved on the outside of the support mesh cylinder, wherein a limiting cylinder sleeved on the outside of the support mesh cylinder is threadedly connected to the surface of the connecting pipe head, and an adhesion plate is connected to the limiting cylinder; further comprising a two-way valve for connecting the connecting pipe head and the handheld rod.

The outer diameter of the locking sleeve is the same as the outer diameter of the connecting pipe head, and the inner diameter of the locking sleeve is the same as the outer diameter of the limiting sleeve.

[0008] Preferably, an arc groove a is formed on the surface of the limiting cylinder, the adhesive plate of the arc block cooperates with the arc groove a, and the inner surface of the adhesive plate is covered with adsorbent foam.

[0009] Preferably, the dust gas conveying path of the dust collection bin is as follows: first suction head, hand handle, two-way valve, pre-filter, gas delivery pipe, and dust collection bin.

[0010] Preferably, the gas flow path within the pre-filter is: direction b, connecting pipe head, direction c within the support mesh cylinder, limiting cylinder, and direction d.

[0011] Preferably, the top of the supporting mesh cylinder is a sealed structure, and the distance between the adhesive plate and the filter bag is 2 mm.

[0012] Preferably, one end of the dual-way valve is connected to a connecting pipe via a threaded connection, and the other end of the connecting pipe is fixedly connected to a connector, with a second suction head connected to the connector via a threaded connection.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a perovskite battery encapsulation dust adsorption device, including a dust removal device for adsorbing dust around the perovskite battery encapsulation station, comprising a mobile trolley 11 and a dust collection bin 12, an air supply pipe 13 connected to the inside of the dust collection bin 12, a handheld lever 14 connected to the inside, and a first suction head 15. The dust gas transport path is: first suction head 15, handheld lever 14, double-way valve 5, pre-filter 4, air supply pipe 13, and dust collection bin 12. The dust gas is filtered by the filter inside the dust collection bin 12, achieving the purpose of collecting dust around the perovskite battery encapsulation station, which can reduce the dust content around the perovskite battery encapsulation station; it also includes a pre-filter 4 for filtering dust particles in the transported gas, comprising a split-connected connecting pipe head 41 and a locking sleeve 42, a support mesh cylinder 44 fixedly connected to the connecting pipe head 41, and a filter bag 43 sleeved on the outside of the support mesh cylinder 44. The pre-filter 4... The dust in the gas transported by the pre-filtered gas supply pipe 13 is filtered through the following paths: direction b, connecting pipe head 41, direction c inside the support mesh cylinder 44, limiting cylinder 7, and direction d. The filter bag 43 filters the dust contained in the gas passing through the support mesh cylinder 44, achieving the purpose of dust adsorption. The surface of the connecting pipe head 41 is threadedly connected to the limiting cylinder 7, which is sleeved on the outside of the support mesh cylinder 44. An adhesive plate 71 is connected to the limiting cylinder 7. The adsorption foam on the adhesive plate 71 has a microporous structure and also plays a role in adsorbing dust. The adhesive plate 71 and the limiting cylinder 7 are separate structures, which makes it easy to manually remove the adhesive plate 71, facilitate the cleaning of the dust adsorbed on the surface of the adhesive plate 71, and facilitate the replacement of the adhesive plate 71. It also includes a two-way valve 5 for connecting the connecting pipe head 41 and the hand handle 14. The two-way valve 5 plays a role in changing the gas flow path and also in sealing the pipeline.

[0022] In this embodiment, one end of the gas supply pipe 13 passes through the locking sleeve 42 and is connected to the limiting cylinder 7. The outer diameter of the locking sleeve 42 is the same as the outer diameter of the connecting pipe head 41, and the inner diameter of the locking sleeve 42 is the same as the outer diameter of the limiting cylinder 7. The limiting cylinder 7 and the connecting pipe head 41 are connected by a simple threaded connection, and the locking sleeve 42 and the limiting cylinder 7 are connected by a simple threaded connection, which facilitates the disassembly of the locking sleeve 42 and the limiting cylinder 7.

[0023] In this embodiment, an arc groove a is provided on the surface of the limiting cylinder 7, and the adhesive plate 71 of the arc block cooperates with the arc groove a. Adsorbent foam is glued to the inner surface of the adhesive plate 71. The adsorbent foam on the adhesive plate 71 has a microporous structure and also plays the role of adsorbing dust. The adhesive plate 71 and the limiting cylinder 7 are separate structures, which makes it easy to manually remove the adhesive plate 71.

[0024] In this embodiment, the dust gas conveying path filtered by the dust collection bin 12 is sequentially: first suction head 15, hand handle 14, double-way valve 5, pre-filter 4, air supply pipe 13, and dust collection bin 12. The gas flow path within the pre-filter 4 is: direction b, connecting pipe head 41, direction c within the support mesh cylinder 44, limiting cylinder 7, and direction d. During the dust gas flow process, some dust in the dust gas is adhered by the filter bag 43 and adhesion plate 71 within the pre-filter 4, preventing dust from clogging the air supply pipe 13.

[0025] In this embodiment, the top of the support mesh cylinder 44 is a sealed structure, the distance between the adhesive plate 71 and the filter bag 43 is 2 mm, the support mesh cylinder 44 supports the filter bag 43, and there is a distance between the filter bag 43 and the adhesive plate 71, which does not affect the flow of gas.

[0026] In this embodiment, one end of the dual-way valve 5 is connected to a connecting pipe 61 by a threaded connection, and the other end of the connecting pipe 61 is fixedly connected to a connector 62. A second suction head 63 is connected to the connector 62 by a threaded connection. The second suction head 63 plays the role of adsorbing dust. When one end of the dual-way valve 5 is closed and the other end is open, the dust gas flows along the path of the second suction head 63, the connector 62, the connecting pipe 61, and the pre-filter 4. The size and shape of the second suction head 63 are different from those of the first suction head 15. The second suction head 63 is a long, flat head shape, which is conducive to dust adsorption in small spaces at the perovskite battery packaging station.

[0027] Working principle and usage process of this utility model:

[0028] When the industrial vacuum cleaner is working, the dust gas delivery path is the first suction head 15, hand handle 14, two-way valve 5, pre-filter 4, air supply pipe 13, and dust collection bin 12. The dust gas is filtered by the filter in the dust collection bin 12 to achieve the purpose of collecting dust around the perovskite battery packaging station, which can reduce the dust content around the perovskite battery packaging station.

[0029] When the dust gas is conveyed through the pre-filter 4, the dust gas flow path is in the b direction, the connecting pipe head 41, the c direction inside the support mesh cylinder 44, the limiting cylinder 7, and the d direction. The filter bag 43 filters the dust contained in the gas passing through the support mesh cylinder 44, thereby achieving the purpose of adsorbing dust.

[0030] The adsorption foam on the adhesive plate 71 has a microporous structure and also plays a role in adsorbing dust. The adhesive plate 71 and the limiting cylinder 7 are separate structures, which makes it easy to manually remove the adhesive plate 71.

[0031] The limiting sleeve 7 and the connecting pipe head 41 are connected by a simple threaded engagement, and the locking sleeve 42 and the limiting sleeve 7 are connected by a simple threaded engagement, which makes it easy to disassemble the locking sleeve 42 and the limiting sleeve 7, and easy to clean or replace the adhesive plate 71 and the filter bag 43.

[0032] When one end of the dual-way valve 5 is closed and the other end is open, the dust gas flows along the path of the second suction head 63, connector 62, connecting pipe 61, and pre-filter 4. The size and shape of the second suction head 63 are different from those of the first suction head 15. The second suction head 63 is a long, flat head shape, which is conducive to dust adsorption in small spaces at the perovskite battery packaging station.

[0033] In summary, the industrial vacuum cleaner of this application features a pre-filtration design for dusty gas entering the pipe and a pipe connection design that facilitates disassembly and cleaning. The dusty gas is transported through the pre-filter 4, the filter bag 43 filters the dust contained in the gas passing through the support mesh cylinder 44, and the adhesion plate 71 adsorbs the dust, thus achieving the purpose of dust adsorption. The second suction head 63 is a long, flat head shape, which is conducive to dust adsorption in small spaces at the perovskite battery packaging station.
