[0003] During the carbon fiber production process, water washing is required to remove residual electrolyte from the surface of the carbon fibers after electrolysis. Existing carbon fiber washing systems typically dilute the electrolyte concentration on the carbon fiber surface in a static water bath, resulting in poor washing results, low processing efficiency, and the need for frequent cleaning of lint and broken fibers. Utility Model Content

[0007] Furthermore, it also includes a plurality of circulation filtration systems, which are connected to the plurality of water washing tanks in a one-to-one correspondence, and the circulation filtration systems are used to circulate and filter the cleaning liquid in the water washing tanks.

[0008] Furthermore, the circulation filtration system includes a circulation pipeline and a circulation pump and a filter arranged on the circulation pipeline, and the inlet and outlet of the circulation pipeline are both connected to the corresponding water washing tank.

[0034] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] It should be noted that in the description of this utility model, the terms "connection" and "installation" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; direct connection or connection through an intermediate medium; mechanical connection or electrical connection. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0037] The utility model provides a carbon fiber water washing device, which has a feed end (i.e., the left end in the figure) and a discharge end (i.e., the right end in the figure). Figure 1 and Figure 2 The device includes several water washing tanks 1, which are arranged in sequence from the feed end to the discharge end and rise in sequence. The water washing tank 1 closest to the discharge end has a water inlet 11; the bottom plate of each water washing tank 1 is inclined from bottom to top from the feed end to the discharge end.

[0038] Reference Figure 2 , Figure 2 The dotted arrow in the figure indicates the running direction of the carbon fiber tow 100. The carbon fiber tow 100 is fed into the device from the feeding end and output from the discharging end. Figure 2 The solid arrow in the figure indicates the direction of water flow. The cleaning liquid is input from the water inlet 11 of the washing tank 1 closest to the discharge end. After the washing tank 1 is filled with cleaning liquid, the cleaning liquid overflows to the next level washing tank 1, and so on, so that each washing tank 1 is filled with cleaning liquid.

[0039] Compared to the existing static water cleaning method, the carbon fiber washing device provided by the present application, during operation, the cleaning liquid flows into each washing tank 1 in sequence from the discharge end of the device to the feed end of the device to rinse the carbon fiber tow 100, thereby improving the washing effect and processing efficiency. The running direction of the carbon fiber tow 100 is opposite to the flow direction of the cleaning liquid in each washing tank 1, which is more conducive to flushing away the residual electrolyte on the surface of the carbon fiber tow 100, further improving the washing effect. The bottom plate of each washing tank 1 is inclined from bottom to top from the feed end to the discharge end. Under the action of the water flow, the hair and broken wires in the washing tank 1 are accumulated on the lower side of the bottom plate of the washing tank 1, thereby achieving the purpose of facilitating the cleaning and collection of the hair and broken wires in the washing tank 1, reducing the frequency and difficulty of manually cleaning the hair and broken wires, and saving labor costs.

[0040] In this embodiment, there are three water washing tanks 1. The number of water washing tanks 1 can be adaptively adjusted according to usage requirements and is not limited here.

[0041] Continue to refer to Figure 1 and Figure 2 The carbon fiber washing device further includes a plurality of smooth rollers 4 disposed above the washing tank 1 and a plurality of washing rollers 5 at least partially disposed within the washing tank 1. The carbon fiber tows 100 pass over the smooth rollers 4 and the washing rollers 5 and are guided by the washing rollers 5 into the washing tanks 1.

[0042] Furthermore, the surface of at least one of the smooth rollers 4 is coated with adsorption cotton 6. In this embodiment, the surface of the smooth roller 4 near the feed end is coated with adsorption cotton 6. The adsorption cotton 6 is used to adsorb residual electrolyte.

[0043] Continue to refer to Figure 1 and Figure 2 The carbon fiber water washing device also includes an overflow tank 9, which is connected to the water washing tank 1 closest to the feed end (i.e., the water washing tank 1 on the far left in the figure). It is used to receive the cleaning liquid overflowing from the water washing tank 1 closest to the feed end, thereby reducing the workload of manually cleaning the overflow cleaning liquid.

[0044] Based on the above structure, the carbon fiber washing device also includes an inlet pipe 81 and an outlet pipe 82, wherein: the inlet of the inlet pipe 81 is connected to the washing liquid storage device, and the outlet of the inlet pipe 81 is connected to the water inlet 11; the inlet of the outlet pipe 82 is connected to the overflow tank 9, and the outlet of the outlet pipe 82 is connected to the recovery device or the washing liquid storage device. During operation, the washing liquid enters the washing tank 1 at the far right through the inlet pipe 81, then overflows into each washing tank 1 in sequence, and finally overflows into the overflow tank 9 and is discharged from the outlet pipe 82. The washing liquid discharged from the outlet pipe 82 can be sent back to the washing tank 1 after filtering, forming a washing liquid circulation loop.

[0045] Furthermore, the carbon fiber washing device also includes a plurality of circulating filtration systems 2, which are connected to a plurality of washing tanks 1 in a one-to-one correspondence.

The inlet and outlet of the circulation line 21 are both connected to the corresponding water washing tank 1. During operation, the cleaning liquid in the water washing tank 1 enters the circulation and filtration system under the action of the circulation pump 22. After the filter 23 filters out the lint and broken threads, the liquid is returned to the water washing tank 1. This further improves the fluidity and cleanliness of the cleaning liquid in the water washing tank 1, enhances the washing effect, and reduces the frequency and difficulty of manual cleaning of lint and broken threads.

[0047] In this embodiment, the outlet of the circulation pipeline 21 faces the carbon fiber tow 100 , so that the circulating water can flush the carbon fiber tow 100 .
