Description

Technical Field

[0001] This utility model relates to the field of silicon wafer production technology, specifically a flower basket crossbar condensate treatment device and a silicon wafer flower basket. Background Technology

[0002] A silicon wafer basket, also known as a process basket or carrier, is a precision tool used in the wet process of photovoltaic cells to hold, fix, and transport silicon wafers; it ensures that the silicon wafers can react safely and uniformly during the intense chemical immersion and cleaning process.

[0003] The wet process for photovoltaic cells mainly includes texturing and post-diffusion cleaning. Each process requires drying. Since the drying chamber is a closed space, and due to factors such as the material of the basket crossbar (usually made of plastics such as PFA and PVDF, whose heat capacity is much lower than that of the silicon wafer) and its installation position (the crossbar is usually located above or to the side of the silicon wafer), water vapor evaporating from the silicon wafer surface is prone to condense on the basket crossbar, and then condense into water droplets on its surface. If these condensed water droplets are not treated in time, the continuously expanding water droplets will drip onto the silicon wafer surface, thus affecting the quality and dryness of the silicon wafer and impacting production quality.

[0004] Based on the above analysis, this solution designs a flower basket crossbar condensate treatment device and a silicon wafer flower basket. Utility Model Content

[0005] The purpose of this invention is to provide a condensate treatment device for a flower basket crossbar and a silicon wafer flower basket. This device can receive and guide the condensate on the flower basket crossbar to separate it from the crossbar, thereby preventing the condensate from dripping onto the silicon wafer surface and affecting the quality and dryness of the silicon wafer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for treating condensate on a basket crossbar is provided. The device is located at the bottom of the basket crossbar and includes a base and a guiding mechanism. The guiding mechanism is disposed on the base and includes a flow-guiding tip and at least one set of flow-guiding inclined plates. The flow-guiding tip is located at the upper end of the flow-guiding inclined plates and can contact the condensate on the basket crossbar and break its surface tension, thereby separating the condensate from the basket crossbar. The flow-guiding inclined plates can receive and treat the condensate.

[0007] As a preferred embodiment, the guide plate includes a heat-conducting support plate. A heating component is arranged on the inner side of the heat-conducting support plate, and a hydrophobic coating is applied to the outer side. The heating component can heat the heat-conducting support plate to form an evaporation surface on its outer side, thereby evaporating the condensate.

[0008] In a preferred embodiment, the heat-conducting support plate includes a metal heat-conducting plate and a heat-insulating pad, and the heating component is disposed between the metal heat-conducting plate and the heat-insulating pad.

[0009] As a preferred embodiment, the heating component is a heating film.

[0010] As a preferred embodiment, the base is provided with a radially extending arc-shaped plate near the bottom, and a collection groove is formed between the arc-shaped plate and the base. The guide plate can guide the condensate into the collection groove.

[0011] As a preferred embodiment, the guiding mechanism includes two sets of guide ramps, which are joined together in an inverted "V" shape, and the guiding tip is the joint end of the two sets of guide ramps.

[0012] As a preferred embodiment, the drainage tip is provided with multiple microgrooves arranged along its length, and the capillary force generated by the microgrooves can quickly adsorb the condensate.

[0013] As a preferred embodiment, the length of the base corresponds to the length of the crossbar of the flower basket, and the base is a frame structure integrally formed with the guide plate.

[0014] This solution also provides a silicon wafer flower basket, which includes a crossbar, and the flower basket crossbar condensate treatment device described in any of the above-mentioned embodiments is provided directly below the crossbar.

[0015] Compared with the prior art, the beneficial effects of this utility model are: The condensate treatment device for the basket crossbar is located directly below the basket crossbar. When steam condenses into water droplets, the guide tip can contact these droplets and break their surface tension, guiding them to the guide plate. The guide plate can then dry and collect the condensate. Therefore, this condensate treatment device can automatically separate the condensate from the basket crossbar, preventing condensate (water droplets) from dripping onto the silicon wafer surface and affecting wafer quality and dryness. This improves silicon wafer production quality and solves existing shortcomings. In summary, this condensate treatment device is simple and compact in structure, automatically breaks the surface tension of water droplets to achieve automatic separation of condensate from the basket crossbar, and prevents condensate from contacting the silicon wafer, significantly improving silicon wafer quality and possessing certain market value and economic benefits.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0024] This embodiment provides a condensate treatment device for a basket crossbar. The device is installed at the bottom of the basket crossbar 60 and includes a base 10 and a guide mechanism 20. In this embodiment, the base 10 can be a frame structure or a closed structure. The base 10 has a supporting counterweight function, providing stable support for the guide mechanism 20. The guide mechanism 20 is mounted on the base 10 and includes a flow-guiding tip 21 and at least one set of flow-guiding inclined plates 22. The flow-guiding tip 21 is located above the flow-guiding inclined plates 22 and 5-8 mm directly below the basket crossbar 60, ensuring that when the steam condenses into water droplets 70, it can just contact the flow-guiding tip 21. Preferably, the base 10 is a rectangular structure, and the flow-guiding inclined plates 22 include two sets. The two sets of flow-guiding inclined plates 22 are joined in an inverted "V" shape, and the flow-guiding tip 21 is the joining end of the two sets of flow-guiding inclined plates 22. Figure 1 As shown in Figure 3, the guide tip 21 can contact the condensate on the basket crossbar 60 and break its surface tension, thereby separating the condensate from the basket crossbar 60 and preventing the condensate from accumulating. The guide plate 22 can receive and process the condensate. It is understood that the tilt angle of the guide plate 22 can be selected according to actual needs. In this embodiment, the guide plate 22 can specifically use at least one of the following methods to process the condensate: collection or drying.

[0025] Understandably, the lengths of the base 10 and the guide mechanism 20 should correspond to the length of the basket crossbar 60 to ensure that the condensate at any position of the basket crossbar 60 can be promptly diverted to the guide ramp 22.

[0026] like Figure 5 As shown, this embodiment provides a schematic diagram of a set of flow guide plates 22. In this structure, the base 10 is a sloping trapezoid, and a set of flow guide plates 22 are disposed on the sloping side of the sloping trapezoid. The top end of the flow guide plate 22 and the top end of the sloping trapezoid are chamfered to form a flow guide tip 21.

[0027] As a preferred embodiment, the guide plate 22 includes a heat-conducting support plate, on the inner side of which a heating component 223 is arranged, and on the outer side which is coated with a hydrophobic coating 224. Figure 4 As shown, the heating component 223 can heat the heat-conducting support plate to form an evaporation surface on its outer side, thereby drying the condensate. Specifically, when there is condensate on the crossbar 60 of the flower basket, the condensate droplets 70 formed will contact the guide tip 21 and, under the action of the guide tip 21, break its surface tension, causing it to flow along the guide tip 21 to the guide slope 22. Since the guide slope 22 has a high temperature, the condensate will be heated and evaporated through the evaporation surface of the guide slope to achieve the purpose of drying.

[0028] In this embodiment, the heat-conducting support plate includes a metal heat-conducting plate 221 and a heat-insulating pad 222. The metal heat-conducting plate 221 is preferably made of copper with a high thermal conductivity, the heat-insulating pad 222 is made of high-temperature cotton, and the heating component 223 is a heating film. The heating component 223 is disposed between the metal heat-conducting plate 221 and the heat-insulating pad 222. The heat-conducting support plate with this structure can ensure that the temperature of the evaporation surface meets the actual needs, and can also avoid temperature loss, thereby improving the working efficiency of the heat-conducting support plate.

[0029] In a preferred embodiment, the base 10 has a radially extending arc-shaped plate 30 near its bottom, which is either welded or integrally formed. A collection groove 40 is formed between the arc-shaped plate 30 and the base 10. The guide plate 22 guides the collected condensate into the collection groove 40. In this embodiment, the number and position of the arc-shaped plates 30 can be selected according to the specific structure of the base 10. Preferably, the base 10 has collection grooves 40 on both its inner and outer sides. Since steam also condenses on the inner side of the guide plate 22, the collection grooves 40 on the inner side of the base 10 are used to collect the condensate condensed on the guide plate 22. Figure 1 As shown in 3 or 5.

[0030] Understandably, the size of the collection tank 40 can be selected according to actual needs. In this embodiment, it is preferably used as a guide tank, with one end connected to a condensate recovery device.

[0031] As a preferred embodiment, the drainage tip 21 is provided with multiple microgrooves 50 arranged along its length. The capillary force generated by these microgrooves 50 can quickly adsorb the condensate, such as... Figure 2 As shown; specifically, as explained above, the drainage tip 21 in this embodiment is part of the guide plate 22, that is, the main material of the drainage tip 21 is a metal heat-conducting plate 221, but it is coated with a hydrophobic coating 224 on the outer layer. The hydrophobic coating 224 may affect the function of the drainage tip 21. In this embodiment, by opening micro-grooves 50, the hydrophobic coating 224 of the drainage tip 21 is removed and the metal heat-conducting plate 221 is exposed. By utilizing the strong adsorption effect of metal on water, the water droplet 70 can be separated from the basket crossbar 60 with a small contact angle. On the other hand, by utilizing the strong capillary force generated by the micropores, once the water droplet 70 comes into contact with the guide tip, it will be instantly sucked into these micro-grooves 50 and quickly diffused along the structure to the entire path, thereby increasing the guiding speed of the water droplet 70. It is understood that the length and depth of the micro-grooves 50 can be selected according to actual needs, and this embodiment does not make specific limitations here.

[0032] As a preferred embodiment, the length of the base 10 corresponds to the length of the basket crossbar 60, and the base 10 is a frame structure integrally formed with the guide plate 22; of course, the base 10 can also be an independent structure.

[0033] The operating principle of the basket crossbar condensate treatment device in this embodiment includes: The device is placed directly below the crossbar 60 of the flower basket. When the condensed water droplets 70 on the crossbar 60 come into contact with the guide tip 21 at a certain angle, the strong capillary force of the micro-groove 50 of the guide tip 21 will quickly adsorb the condensate and diffuse it along the micro-groove 50, and then guide it to the guide plate 22. Most of the condensate flows into the collection tank 40 along the guide plate 22, and the remaining part of the condensate will be evaporated by the evaporation surface of the guide plate 22.

[0034] In summary, the condensate treatment device of this embodiment is simple and compact in structure, and can automatically break the surface tension of water droplets to achieve automatic separation of condensate from the basket crossbar 60. It also uses a combination of collection and evaporation to treat condensate, avoiding contact between condensate and silicon wafers, which can significantly improve the quality of silicon wafers and has certain market value and economic benefits.

[0035] As a preferred embodiment, this embodiment provides a silicon wafer basket, including a crossbar 60, with the basket crossbar condensate treatment device of the above embodiment located directly below the crossbar 60. Figure 3 Or as shown in Figure 5.

[0036] The silicon wafer basket structure enables automatic separation of condensate from the crossbar 60, and uses a combination of collection and evaporation to treat the condensate, preventing the condensate from accumulating on the crossbar 60 and falling onto the silicon wafer. This significantly improves the quality of the silicon wafer and has certain market value and economic benefits.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
