Abstract
Description
Technical Field
[0001] This application relates to the field of solar cell manufacturing technology, and in particular to a leakage collection device and a tank-type cleaning equipment. Background Technology
[0002] With the growing global demand for renewable energy, solar energy, as a clean and sustainable energy source, has received widespread attention. Texturing the silicon wafer surface is a crucial step in solar cell manufacturing. The purpose of silicon wafer texturing is to reduce sunlight reflection loss on the wafer surface and increase the path length of light within the wafer, thereby improving the photoelectric conversion efficiency of the solar cell. After texturing, the silicon wafer typically requires cleaning in a washing tank to remove residual impurities and byproducts generated during the texturing process, resulting in a cleaner wafer surface.
[0003] During the cleaning process of silicon wafers, chemical agents (such as hydrofluoric acid and sodium hydroxide) are typically used to clean the wafers in a cleaning tank. However, during the cleaning process, leaks of chemical solutions can occur. When leaks occur, operators need to use absorbent cotton to cover the leak and absorb the liquid, then dispose of the cotton directly in the chemical waste bin. Operators inevitably come into contact with the solutions during the leak handling process, and these chemical reagents are highly corrosive, thus posing a risk to their safety and health.
[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.
[0030] like Figures 1-3 As shown, in a first aspect, embodiments of this application may provide a leakage collection device, which may include:
[0031] The collection body 1 is provided with a first collection chamber 11, which is used to collect the leakage of the cleaning tank. A collection hole 12 is provided on the bottom wall of the first collection chamber 11.
[0032] A spray section is provided in the collection body 1. The spray section sprays liquid to flush the leaked liquid in the first collection chamber 11 into the collection hole 12.
[0033] The collection hole 12 is used to connect to the recovery tank 2 and to guide the leaked liquid in the first collection chamber 11 into the recovery tank 2.
[0034] In this embodiment, when the cleaning tank leaks, the leaked liquid flows into the first collection chamber 11. Then, through the rinsing action of the spray section, the leaked liquid is quickly collected into the recovery box 2 through the collection hole 12, reducing the consumption of manual processing resources and making the recovery of leaked liquid safer, more convenient and faster. Compared with using acid-absorbing cotton to recover leaked liquid, the leaked liquid treatment device of this application greatly reduces the contact between operators and leaked liquid, improves the efficiency of leaked liquid recovery, and ensures the safety and health of operators.
[0035] In an optional embodiment, the recycling bin 2 is detachably disposed at the bottom of the collection body 1. After the leaked liquid in the first collection chamber is collected into the recycling bin, the operator can remove the recycling bin from the collection body, pour out the leaked liquid from the recycling bin for treatment, and then install the empty recycling bin back onto the collection body.
[0036] In an optional embodiment, the leakage collection device includes a detection element 4 disposed in the collection body 1, and the detection element 4 is used to detect leakage. In this embodiment, the detection element 4 is located in the collection hole 12, and the size of the detection element 4 is smaller than the aperture of the collection hole 12, so as not to affect the flow of leakage in the collection hole 12; the detection element 4 is used to detect leakage, thereby realizing the collection of leakage.
[0037] In an optional embodiment, the spray section is disposed above the edge of the collection body 1; when the detection element 4 detects leakage, it controls the spray section to spray liquid to rinse the leakage on the inner wall of the first collection chamber 11.
[0038] In this embodiment, the detection element 4 is connected to an external control unit PLC system. When the detection element 4 detects leakage, the control unit PLC system will activate the spray unit to spray pure water to collect the leakage, thereby quickly collecting the leakage at the bottom of the first collection chamber 11. This improves the leakage collection efficiency and further reduces manual intervention, ensuring the safety of the operators. Furthermore, the sprayed pure water can wash away the leakage adhering to the inner wall of the first collection chamber 11, reducing the likelihood of leakage adhering to the inner wall. After the leakage is collected, the spray unit can also automatically clean the collection body 1 by spraying pure water.
[0039] In some embodiments, the detection element includes a leakage detection unit and an acid / alkalinity detection unit, both of which are electrically connected to the control unit PLC system. The leakage detection unit is used to detect whether leakage has occurred in the cleaning tank, while the acid / alkalinity detection unit is used to detect the acidity or alkalinity of the leaked liquid. The leakage detection unit can be a capacitive level sensor, an ultrasonic level gauge, or a guided wave radar level gauge. The acid / alkalinity detection unit can be a pH probe / electrode or an online pH analyzer.
[0040] In an optional embodiment, the spray unit includes a first spray assembly and a second spray assembly, which are disposed opposite to each other above the edge of the collecting body 1. The first spray assembly includes a first spray pipe 31 and a plurality of first spray heads 32. The first spray pipe 31 is disposed above the edge of the collecting body 1, and the plurality of spray heads are disposed at intervals on the first spray pipe 31. The first spray heads 32 spray liquid to flush the leakage on the first inclined plate 15 into the collecting hole 12. The second spray assembly includes a second spray pipe 33 and a plurality of second spray heads 34, which are disposed above the edge of the collecting body 1. The plurality of spray heads are disposed at intervals on the second spray pipe 33, and the second spray heads 34 spray liquid to flush the leakage on the second inclined plate 16 into the collecting hole 12. The first spray pipe 31 and the second spray pipe 33 are disposed opposite to each other.
[0041] In this embodiment, when the leakage detection unit in the detection component detects leakage, the control unit PLC system receives the data and controls the first spray head 32 to spray pure water from the first spray pipe 31 to rinse the leakage. Similarly, the second spray head 34 sprays pure water from the second spray pipe 33 to rinse the leakage, thereby fully and quickly collecting the leakage into the recovery tank 2. In this embodiment, there are seven first spray heads 32, which are evenly spaced on the first spray pipe 31; there are also seven second spray heads 34, which are evenly spaced on the second spray pipe 33. The evenly spaced first spray heads 32 and second spray heads 34 can improve the uniformity of pure water spraying, ensuring that the pure water can fully rinse the inner wall of the first collection chamber 11, rinsing all the leakage on the inner wall of the first collection chamber 11 into the collection hole 12.
[0042] In an optional embodiment, the recycling bin 2 includes a first diversion section 21, a second diversion section 22, a receiving tube 23, a first baffle 24, and a second baffle 25. The receiving tube 23 is connected to the collection hole 12. The first baffle 24 is openable and closed between the first diversion section 21 and the receiving tube 23, and the second baffle 25 is openable and closed between the second diversion section 22 and the receiving tube 23.
[0043] In this embodiment, the leaked liquid enters the receiving tube 23 through the collection hole 12, and then flows from the receiving tube 23 into the first diversion section 21 and the second diversion section 22. The first diversion section 21 and the second diversion section 22 can collect the same or different leaked liquids, and the acid-base detection section of the detection element 4 can detect the acidity or alkalinity of the leaked liquid in the receiving tube 23. When the detection element 4 detects that the leaked liquid is acidic, the control unit PLC system receives the data and controls the first baffle 24 to open and the second baffle 25 to close, so as to guide the leaked liquid into the first diversion section 21; when the detection element 4 detects that the leaked liquid is alkaline, the control unit PLC system receives the data and controls the first baffle 24 to close and the second baffle 25 to open, so as to guide the leaked liquid into the second diversion section 22. Therefore, the leaked liquid collection device of this application can collect leaked liquid while also separating and recovering acidic and alkaline leaked liquids, thereby further ensuring the safety of the operators. It should be noted that mixing acidic and alkaline leaks will cause a reaction. The entire reaction is violently exothermic, which will cause the temperature of the mixed solution to rise sharply, and may even cause the solution to boil or splash, causing burns to the human body. Therefore, mixing acidic and alkaline leaks poses a significant safety hazard.
[0044] In an optional embodiment, the collecting body 1 includes a first side plate 13, a second side plate 14, a first inclined plate 15, and a second inclined plate 16. The first side plate 13 and the second side plate 14 are arranged opposite to each other, and the first inclined plate 15 and the second inclined plate 16 are both disposed between the first side plate 13 and the second side plate 14. The first inclined plate 15 and the second inclined plate 16 are connected by a bottom plate, and a collecting hole 12 is disposed through the bottom plate. The first side plate 13, the second side plate 14, the first inclined plate 15, the second inclined plate 16, and the bottom plate enclose a first collecting cavity 11. In this embodiment, the bottom plate is located on the bottom wall of the first collecting cavity 11. When leakage occurs, there is no need to use absorbent cotton to absorb the leakage; the leakage flows directly into the first collecting cavity 11 and is collected. Therefore, the first collecting cavity 11 formed by the first side plate 13, the second side plate 14, the first inclined plate 15, the second inclined plate 16, and the bottom plate can collect the leakage, reduce the contact between the leakage and the operator, and thus improve the safety and health of the operator. This design can guide the leakage, improving the efficiency of leakage treatment and reducing the adhesion of leakage to the inner wall of the first collection chamber 11. In this embodiment, both the first inclined plate 15 and the second inclined plate 16 can be inclined to guide the leakage into the collection hole 12.
[0045] In an optional embodiment, the collecting body 1 further includes a second collecting cavity 18. The periphery of the bottom plate is connected to the first inclined plate 15 and the second inclined plate 16 through an extension plate 19. The bottom plate and the extension plate 19 enclose the second collecting cavity 18, and the collecting hole 12 communicates with the first collecting cavity 11 through the second collecting cavity 18.
[0046] In this embodiment, the second collection chamber 18 is provided to quickly collect the leaked liquid in the first collection chamber 11 and then recover the leaked liquid from the collection hole 12 to the recovery tank 2, thereby further improving the efficiency of leaked liquid collection.
[0047] In an optional embodiment, the base plate includes a first connecting plate 171, a second connecting plate 172, and a carrier plate 173, with a collection hole 12 extending through the carrier plate 173; one end of the carrier plate 173 is connected to the first connecting plate 171, and the other end is connected to the second connecting plate 172; the end of the first connecting plate 171 near the carrier plate 173 is inclined away from the first collection chamber 11, and the end of the second connecting plate 172 near the carrier plate 173 is inclined away from the first collection chamber 11; the first connecting plate 171 and the second connecting plate 172 are used to guide the leakage in the second collection chamber 18 into the collection hole 12. When a leak occurs in the cleaning tank, the leaked liquid flows rapidly into the first collection chamber 11 under the guidance of the first inclined plate 15 and the second inclined plate 16. It first collects at the bottom of the first collection chamber 11, and then flows rapidly onto the carrier plate 173 under the guidance of the first connecting plate 171 and the second connecting plate 172. That is, the leaked liquid flows into the recovery tank 2 through the collection hole 12 on the carrier plate 173, thus completing the collection of the leaked liquid.
[0048] Secondly, embodiments of this application may provide a tank-type cleaning device, which includes a cleaning tank and a leakage collection device from any of the above embodiments, with the leakage collection device disposed at the bottom of the cleaning tank.
