Abstract
Description
Technical Field
[0001] This utility model relates to the field of ink recycling technology, specifically to an electrode spraying platform with ink recycling function. Background Technology
[0002] In the fields of fuel cells and water electrolysis, electrode materials are typically precious metals. To address the problem of precious metal waste, many studies have begun to explore the fabrication process of plated electrode (PTE) methods. However, the porous transport layer (PTL), which serves as the electrode "skeleton," has a through-hole structure.
[0003] The Porous Transport Layer (PTL) method for electrode preparation has been widely studied. In this method, the porous transport layer (PTL) that serves as the electrode "skeleton" is often a porous structure such as titanium mesh. However, when the catalyst layer is coated with ink, the porous structure inevitably leads to ink leakage. Some platforms do not have a dedicated recovery structure, which makes it difficult to collect and utilize the leaked ink and results in low flow efficiency, making it impossible to achieve full recovery and cleaning of the ink. Therefore, this invention provides an electrode coating platform with ink recovery function. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides an electrode spraying platform with ink recovery function. This solves the problems that, when spraying ink onto the catalyst layer, the through-hole structure inevitably leads to ink leakage, some platforms do not have a dedicated recovery structure, making it difficult to collect and utilize the leaked ink, and the low flow efficiency makes it impossible to achieve full ink recovery and cleaning.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrode spraying platform with ink recovery function, comprising a mounting bracket, wherein the mounting bracket is provided with an ink recovery mechanism for the electrode spraying platform, the recovery mechanism comprising:
[0006] The recycling component includes a titanium mesh connected to the upper end of a mounting bracket via a locking assembly, a vacuum heating plate seat on the inner side of the mounting bracket, vacuum holes evenly distributed on the upper surface of the vacuum heating plate seat, a Teflon film substrate adhered to the surface of the vacuum heating plate seat, and a sloped surface on the surface of the vacuum heating plate seat extending to the bottom of the inner side of the mounting bracket and penetrating to form a guide groove.
[0007] The cleaning component includes a groove formed in the inner wall of the mounting bracket, and a brush connected by a reciprocating component is disposed inside the groove.
[0008] Preferably, the vacuum heating plate holder includes a heating wire and a vacuum pump, and the inclined surface on the surface of the vacuum heating plate holder has an inverted V-shaped structure.
[0009] Preferably, the locking assembly includes a fixing plate fixed to the inner wall of the mounting bracket, a fixing bolt fixed to the upper end of the fixing plate, a titanium mesh located on the upper surface of the fixing plate and inserted into the fixing bolt, and a locking buckle threaded onto the outer wall of the fixing bolt.

[0013] Beneficial effects
[0014] This invention provides an electrode spraying platform with ink recovery function. Compared with the prior art, it has the following advantages:
[0015] Firstly, in this invention, some ink leaks through the titanium mesh through-holes onto the surface of the Teflon film substrate. The vacuum pump inside the vacuum heating plate holder draws air through the vacuum holes, adsorbing the Teflon film substrate onto the vacuum heating plate holder. Simultaneously, the heating wire heats the ink to dry it. The ink leaking onto the film surface flows towards the edge along the inverted V-shaped slope under the guidance of gravity and the inclined surface, and falls into the collection shell through the guide channel. The inverted V-shaped slope design causes the ink to converge towards the edge, accelerating the guiding efficiency and preventing ink accumulation on the film surface. The guide channel and the collection shell are linked to form a closed recovery path, preventing ink leakage, improving recovery efficiency, saving precious metal catalysts, ensuring film fixation, accelerating ink drying with heating, facilitating collection, and reducing spray diffusion pollution.
[0016] Secondly, the reciprocating screw of this invention rotates via a motor, causing a sliding plate to slide back and forth along the screw axis within a groove. The brush moves with the sliding plate to clean the residual ink on the surface of the vacuum heating plate seat and the Teflon film substrate. The cleaned ink also flows into the collection shell through the inclined surface and guide groove, reducing the amount of manual cleaning and ensuring that leaked and residual ink can be effectively recycled, thus improving the ink recovery rate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 This utility model provides a technical solution: an electrode spraying platform with ink recovery function, including a mounting bracket 1, on which an ink recovery mechanism for the electrode spraying platform is provided, the recovery mechanism including:
[0025] The recycling component includes a titanium mesh 203 connected by a locking component at the upper end of the mounting bracket 1, a vacuum heating plate seat 3 on the inner side of the mounting bracket 1, vacuum holes 302 uniformly opened on the upper end surface of the vacuum heating plate seat 3, a Teflon film substrate 304 attached to the surface of the vacuum heating plate seat 3, a slope 301 opened on the surface of the vacuum heating plate seat 3, and a guide groove 303 opened through the slope 301 extending to the bottom of the inner side of the mounting bracket 1.
[0026] The cleaning component includes a groove 4 opened on the inner wall of the mounting bracket 1, and a brush 403 connected by a reciprocating component is provided inside the groove 4.
[0027] In a preferred embodiment, the vacuum heating plate holder 3 includes a heating wire and a vacuum pump. The inclined surface 301 has an inverted V-shaped structure on the surface of the vacuum heating plate holder 3. A first slide rail bracket 5 is fixed to the lower end face of the mounting bracket 1. A collection shell 501 is slidably connected inside the first slide rail bracket 5. The collection shell 501 corresponds to the area directly below the guide groove 303. The ink nozzle 7 sprays ink onto the titanium mesh 203. Some of the ink seeps through the through holes of the titanium mesh onto the surface of the Teflon film substrate 304. The vacuum pump inside the vacuum heating plate holder 3 evacuates air through the vacuum hole 302, adsorbing the Teflon film substrate 304 onto the vacuum heating plate holder 3. At the same time, the heating wire heats the ink to dry it, allowing it to seep onto the film surface. Under the guidance of gravity and the inclined plane 301, the ink on the surface flows towards the edge along the inverted V-shaped inclined plane, and falls into the collection shell 501 through the guide channel 303. The design of the inverted V-shaped inclined plane 301 makes the ink converge towards the edge, accelerates the guiding efficiency, and avoids the ink accumulation on the film surface. The guide channel 303 and the collection shell 501 are linked to form a closed recycling path to prevent ink leakage, improve recycling efficiency, and save precious metal catalysts. The vacuum hole 302 ensures the film is fixed, and heating accelerates the drying of ink, which is convenient for collection and reduces spray diffusion pollution. The vacuum pump model is GL-810 and the heating wire model is Cr20Ni80, both of which are existing technologies and will not be described in detail.
[0028] In a preferred embodiment, the locking assembly includes a fixing plate 2 fixed to the inner wall of the mounting bracket 1. A fixing bolt 201 is fixed to the upper end of the fixing plate 2. A titanium mesh 203 is located on the upper surface of the fixing plate 2 and is inserted into the fixing bolt 201. A locking buckle 202 is threaded onto the outer wall of the fixing bolt 201. The titanium mesh 203 is fixed to the upper end of the mounting bracket 1 by the locking assembly. Specifically, the titanium mesh 203 is placed on the fixing plate 2 and fixed by the fixing bolt 201 and the locking buckle 202. The operation is simple, it is detachable, and it is convenient to replace the titanium mesh 203. It is suitable for porous transmission layers of different sizes.
[0029] In a preferred embodiment, the reciprocating assembly includes a reciprocating screw 401 rotatably connected inside a slide groove 4. A sliding plate 402 is slidably connected to the inner wall of the slide groove 4. One end of the sliding plate 402 located inside the slide groove 4 is threadedly connected to the reciprocating screw 401. Brushes 403 are evenly distributed on the lower end face of the sliding plate 402. The reciprocating screw 401 is rotated by a motor, which drives the sliding plate 402 to slide back and forth along the screw axis inside the slide groove 4. The brushes 403 move with the sliding plate 402 to clean the residual ink on the surface of the vacuum heating plate seat 3 and the Teflon film substrate 304. The cleaned ink also flows into the collection shell 501 through the inclined surface 301 and the guide groove 303, reducing the amount of manual cleaning work and ensuring that leaked and residual ink can be effectively recovered, thereby improving the ink recovery rate. The motor model is N30-050.
[0030] In a preferred embodiment, a support frame 6 is fixed to the outer wall of the mounting bracket 1, and a second slide rail bracket 601 is fixed to the upper end of the support frame 6. A protective cover 602 is slidably connected inside the second slide rail bracket 601. An ink nozzle 7 for processing is provided above the mounting bracket 1. The protective cover 602 is slidably connected to the second slide rail bracket 601. According to the needs of the spraying operation, the protective cover 602 can be slid to adjust its position to ensure that it can cover the spraying area to a certain extent and reduce the leakage of ink over a large area.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0032] When operating the electrode spraying platform with ink recovery function of this utility model, firstly, the titanium mesh 203 is fixed to the upper end of the mounting bracket 1 by the locking assembly. Specifically, the titanium mesh 203 is placed on the fixing plate 2 and fixed by the fixing bolt 201 and the locking buckle 202 to ensure that the titanium mesh is stable and removable, so as to facilitate subsequent replacement to adapt to porous transmission layers of different sizes. Next, the Teflon film substrate 304 is attached to the upper end surface of the vacuum heating plate seat 3 to ensure that all vacuum holes 302 are covered, and the collection shell 501 is prepared to slide and connect in the first slide rail bracket 5, corresponding to the direct below the guide groove 303.
[0033] Subsequently, the ink nozzle 7 is activated to spray the titanium mesh 203. During the spraying process, some ink leaks through the through-holes of the titanium mesh onto the surface of the Teflon film substrate 304. At this time, the vacuum pump in the vacuum heating plate holder 3 draws air through the vacuum hole 302, tightly adsorbing the Teflon film substrate 304 onto the vacuum heating plate holder 3. Simultaneously, the heating wire begins to heat, causing the ink to dry rapidly. The ink that leaks onto the film surface, guided by gravity and the inverted V-shaped slope 301, flows along the slope to the edge and falls precisely into the collection shell 501 through the guide groove 303, forming a closed recovery path. This effectively prevents ink leakage, improves recovery efficiency, and saves precious metal catalyst. After the spraying operation is completed, the reciprocating assembly is activated, reciprocating... The screw 401 rotates via a motor, causing the sliding plate 402 to slide back and forth along the screw axis within the slide groove 4. The brush 403 moves with the sliding plate 402, thoroughly cleaning the residual ink on the surface of the vacuum heating plate seat 3 and the Teflon film substrate 304. The cleaned ink also flows into the collection shell 501 through the inclined surface 301 and the guide groove 303, reducing the workload of manual cleaning and ensuring that leaked and residual ink can be effectively recovered. In addition, according to the needs of the spraying operation, the coverage area of the sliding protective cover 602 can be adjusted by adjusting its position on the second slide rail bracket 601 to ensure that the spraying area is effectively protected, reduce large-area ink leakage, protect the safety of operators, and maintain a clean environment.
