Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of bipolar plate impregnation processing, and particularly relates to a graphite plate cleaning and impregnation tool. BACKGROUND

[0002] The statements herein merely provide background technology related to the present disclosure, and do not necessarily constitute prior art.

[0003] A fuel cell is a power generation device that directly converts chemical energy into electrical energy through an electrochemical reaction of hydrogen fuel and an oxidant, and a graphite bipolar plate needs to be installed in the fuel cell. In the production process of the graphite bipolar plate, a resin needs to be impregnated into the pores inside the graphite bipolar plate by using an impregnation device. However, when the current impregnation device is used to impregnate or clean multiple graphite plates, the graphite bipolar plates are often stuck together. After impregnation or cleaning is completed, it is difficult to separate the stuck graphite bipolar plates, and subsequent separate operation and separation are required. However, this process not only consumes time and effort, but also often causes the stuck graphite plates to break or be damaged during the separation process, resulting in the graphite plates being unable to be used, thereby reducing the overall production efficiency.

[0023] As Figure 1As shown in 4, the embodiment provides a graphite plate cleaning and dipping tool, which comprises a dipping cage, the dipping cage is a box type structure, comprising a baffle 3 horizontally arranged at the top, two groups of first surrounding plates 1 and two groups of second surrounding plates 2 vertically arranged, and a support plate 4 horizontally arranged at the bottom. A plurality of partition nets for separating graphite bipolar plates are arranged in the dipping cage, the partition nets are parallel to each other and have equal spacing, so as to ensure the uniformity of the distribution of the graphite bipolar plates during the dipping process and the efficiency of the dipping.

[0024] Specifically, as shown in Figure 1 and Figure 2 , the vertical edge of the first surrounding plate 1 is provided with a clamping groove, and the vertical edge of the second surrounding plate 2 is provided with a connecting block corresponding to the clamping groove of the first surrounding plate 1. By inserting the connecting block into the clamping groove of the first surrounding plate 1, the tight connection between the two surrounding plates is realized.

[0025] The support plate 4 is provided with a plurality of and is fixedly connected with the inner bottom of the first surrounding plate 1 at equal intervals.

[0026] Specifically, as shown in Figure 2 and Figure 3 , the support plate 4 is provided with at least 5, and the support plate 4 is fixedly connected at equal intervals on the inner bottom of the first surrounding plate 1, and each support plate 4 is provided with a through hole connected with the partition net. The through hole provides stable support for the partition net, enhancing the stability of the overall structure of the partition net.

[0027] As shown in Figure 2 , the partition net is composed of a horizontal long steel pipe 6 and a plurality of vertical short steel pipes 5 connected vertically, and the short steel pipes 5 are arranged at equal intervals on the long steel pipe 6.

[0028] Specifically, the spacing of the short steel pipe 5 on the long steel pipe 6 is equal to the distribution spacing of the support plate 4, which not only ensures the structural beauty of the partition net, but also ensures that the support plate 4 can be evenly distributed on the partition net, thereby enhancing the overall support effect and stability.

[0029] As shown in Figure 2 , a plurality of through holes for conveniently installing and fixing the partition net are designed in the top region of the second surrounding plate 2, and the long steel pipe 6 is connected to the top of the second surrounding plate 2 by plug-in connection, which is not only firm but also convenient for disassembly and adjustment. At the same time, the short steel pipe 5 also adopts a similar plug-in technology, which is tightly connected with the support plate 4, ensuring the stability and reliability of the whole structure.

[0030] As shown in Figure 2As shown, the top of the first enclosure 1 is provided with an outwardly curved limiting plate 9, the length of which is less than that of the first enclosure 1, and a notch consistent with the width of the baffle plate is provided on the limiting plate 9. An outwardly curved connecting plate 8 is provided on the vertical edge of the first enclosure 1, and a connecting hole for mounting the handle 7 is provided on the connecting plate 8.

[0031] On the top of the first enclosure 1, an outwardly curved limiting plate 9 is designed, which is slightly shorter than the length of the first enclosure 1, and a notch consistent with the width of the baffle plate 3 is carefully provided on the limiting plate 9. The baffle plate 3 is semicircular at both ends, and can be embedded in the limiting plate 9 through the notch, and can slide on the limiting plate 9, which can prevent the graphite bipolar plate from sliding out of the impregnation cage, while maintaining the compactness of the overall structure.

[0032] On the vertical edge of the first enclosure 1, an outwardly curved connecting plate 8 is also designed, which not only strengthens the structural strength of the enclosure, but also has a connecting hole for mounting the handle 7, so that the operator can easily lift or lower the impregnation cage by the electric hoist, thereby improving the efficiency of production.

[0033] Working principle:

[0034] When using the impregnation cage for the impregnation treatment of graphite bipolar plates, first, the baffle plate 3 at the top of the impregnation cage is disassembled. Next, the graphite bipolar plates that need to be impregnated are placed between each layer of the partition net in the impregnation cage. The role of the partition net is to ensure that the graphite bipolar plates are evenly distributed, avoiding overlapping or stacking during the impregnation process. After placement, the disassembled baffle plate 3 is reinstalled at the top of the impregnation cage to ensure the stability of the graphite bipolar plates in subsequent operations. Then, the entire impregnation cage is lifted using the electric hoist and moved to the designated impregnation and cleaning area. Upon arrival at the area, the operation of impregnating and cleaning the graphite bipolar plates can begin to ensure that the impurities on the surface are thoroughly removed.

[0035] Although the specific embodiments of the present disclosure have been described above in conjunction with the accompanying drawings, they are not intended to limit the scope of protection of the present disclosure. Those skilled in the art should understand that various modifications or variations can be made to the technical solutions of the present disclosure without the need for creative labor, and such modifications or variations are still within the scope of protection of the present disclosure.
