[0024] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0025] The quality of carbon fiber is determined by the quality of its precursor, and the key to ensuring the quality of the precursor is the control of each process. In the washing process, the carbon fiber precursor needs to replace the solvent to ensure the purity of the prepared precursor and prevent the occurrence of "fusion" in the later preparation process, which can cause filament breakage during oxidation and carbonization, thereby preparing high-performance carbon fiber. In this process, the spraying nozzle washes the solidified yarn, and the continuous positioning spraying water washing method is adopted to ensure that the residual solvent after washing is ≤100ppm, and the number of positioning spraying water washing positions is 2-10. Excessive pressure or too much water spraying of single yarn during the washing process can cause fuzzing and filament breakage during the production of the precursor.

[0028] ReferenceFigures 4-6 As shown, the spraying nozzle 601 is provided with a sliding assembly, and the spraying cover 6 is sleeved on the sliding assembly. The spraying cover 6 is internally provided with a horn shape. The position of the spraying cover 6 close to the spraying nozzle 601 is gradually tightened and narrowed, and the position of the spraying cover 6 away from the spraying nozzle 601 is gradually spread and widened. The sliding assembly is used for displacing the spraying cover 6 sleeved on the spraying nozzle 601. The spraying range and spraying pressure of the spraying nozzle 601 are controlled by the displacement of the spraying cover 6. The spraying cover 6 and the spraying joint 503 are provided with an elastic assembly. The elastic assembly is used in cooperation with the sliding assembly to limit and fix the spraying cover 6, so as to avoid the displacement of the spraying cover 6 under the water pressure.

[0029] The nozzle sleeve 602 is threadedly connected with the spraying nozzle 601. The nozzle sleeve 602 is sleeved on the spraying nozzle 601. The nozzle sleeve 602 is provided with a plurality of first sliding grooves 6021 and second sliding grooves 6022. The first sliding grooves 6021 and the second sliding grooves 6022 are used for displacing and limiting the spraying cover 6. The spraying cover 6 is provided with a pair of clamping blocks 6023. The clamping blocks 6023 are fixedly connected with the spraying cover 6. The length and width of the clamping blocks 6023 are matched with the width of the first sliding grooves 6021 and the second sliding grooves 6022. That is, the clamping blocks 6023 are matched with the first sliding grooves 6021 and the second sliding grooves 6022. The clamping blocks 6023 can slide along the first sliding grooves 6021 and the second sliding grooves 6022.

[0030] Reference Figures 4-6 As shown, one end of the first sliding groove 6021 transversely penetrates the nozzle sleeve 602. The first sliding groove 6021 includes a transverse groove and a plurality of longitudinal grooves. The clamping blocks 6023 on the spraying cover 6 can slide into the first sliding groove 6021 and sleeve the spraying cover 6 on the nozzle sleeve 602. The first sliding grooves 6021 and the second sliding grooves 6022 are connected in communication. The clamping blocks 6023 can be used to move the spraying cover 6 along the transverse first sliding groove 6021. In this process, the relative position of the spraying cover 6 and the nozzle of the spraying nozzle 601 is adjusted. The spraying range of the spraying nozzle 601 is restricted by adjusting the relative position of the spraying cover 6 and the spraying nozzle 601. After the spraying cover 6 reaches the appropriate position, the spraying cover 6 can be rotated to make the clamping blocks 6023 thereon slide along the longitudinal first sliding groove 6021, and finally make the clamping blocks 6023 reach the second sliding groove 6022 at the end of the longitudinal first sliding groove 6021. The clamping blocks 6023 on the spraying cover 6 are clamped to the second sliding groove 6022 in cooperation with the use of the elastic assembly, so as to limit and fix the spraying cover 6 after adjusting the spraying cover 6.

[0031] Reference Figures 4-6As shown, the elastic assembly is used to limit and fix the spray cover 6, and the elastic assembly comprises a connecting ring 603 and a spring 6031. The connecting ring 603 serves to fix the spring 6031, and the connecting ring 603 is fixedly connected with a connecting pipe 6032 inside. One end of the connecting pipe 6032 is inserted into the nozzle sleeve 602, and when the connecting pipe 6032 is inserted into the nozzle sleeve 602, the spring 6031 on the connecting ring 603 is wrapped outside the nozzle sleeve 602 and spirally wrapped therein. The other end of the connecting pipe 6032 is threadedly connected to the spray joint 503, that is, the connecting ring 603 is installed between the spray joint 503 and the nozzle sleeve 602. One end of the spring 6031 is fixedly connected to the connecting ring 603, and the other end is fixedly connected with the connecting pipe 6032. The spring 6031 is used to push the spray cover 6 and give it a force away from the spray nozzle 601. A clamping groove 6033 is formed on the spray cover 6, and the size of the clamping groove 6033 matches the size of the connecting pipe 6032, that is, the connecting pipe 6032 can be clamped on the clamping groove 6033 and exert a pushing force on the spray cover 6 under the action of the spring 6031. The spring 6031 is a compression spring, and when it is desired to move the spray cover 6 to the direction close to the spray nozzle 601, the spring 6031 is compressed, and when it is desired to move the spray cover 6 to the direction away from the spray nozzle 601, the spring 6031 is stretched.

[0032] Under the joint action of the sliding assembly and the elastic assembly, when it is necessary to adjust the position of the spray cover 6 relative to the spray nozzle 601, the spray cover 6 can be manually dragged or twisted to make the clamping block 6023 thereon move along the tracks of the first sliding groove 6021 and the second sliding groove 6022. After the spray cover 6 reaches the predetermined position, the spray cover 6 is twisted to make the clamping block 6023 thereon reach the position of the second sliding groove 6022 along the first sliding groove 6021, and then the hand is released. At this time, the spring 6031 exerts a pushing force thereon, and the clamping of the clamping block 6023 and the second sliding groove 6022 realizes the fixation and limitation of the spray cover 6.

[0033] Reference Figures 2-3 As shown, the fixed plate 4 is provided with a sliding rail 401, and the sliding rail 401 is provided with a sliding block 402. The sliding block 402 cooperates with the sliding rail 401, and the sliding block 402 can move along the track inside the sliding rail 401, and simultaneously drive the water pipe support 5 fixedly connected to the sliding block 402 to move up and down along the direction of the sliding rail 401. When the water pipe support 5 moves, the spray nozzle 601 installed on the water pipe support 5 also moves up and down, so as to change the vertical distance between the spray nozzle 601 and the carbon fiber precursor, and further control the spraying range and the force generated by the spraying on the carbon fiber precursor.

[0034] Reference Figures 2-3As shown, the water pipe rack 5 is provided with a plurality of water pipe interfaces 501, and a plurality of hoses 502 are installed on the water pipe interfaces 501, wherein the hoses 502 are elastic hoses, and the weight of the elastic hoses is light, so that the hoses 502 can conveniently follow the synchronous movement of the water pipe rack 5 when the water pipe rack 5 is displaced upward or downward. The slide rail 401 and the slide block 402 are used in the prior art, and a locking device for locking the position of the slide block 402 relative to the slide rail 401 is installed on one side of the slide block 402, and the locking device is sufficient to fix the water pipe rack 5 after the water pipe rack 5 is displaced to the corresponding position.

[0035] In specific use, the body 1 of the carbon fiber precursor water washing equipment pulls the carbon fiber precursor, and after the carbon fiber precursor is washed by the washing assembly in the body 1, the carbon fiber precursor is transferred to the body of the next process. When the carbon fiber precursor is washed, the vertical distance between the spray nozzle 601 and the carbon fiber precursor and the spray range of the spray nozzle 601 can be controlled by using the spray cover 6, and the influence of the spraying of the spray nozzle 601 on the tension of the carbon fiber precursor is comprehensively controlled. The water pipe rack 5 can be manually pulled to move along the direction of the slide rail 401, so as to change the vertical distance between the spray nozzle 601 and the carbon fiber precursor, and the position of the water pipe rack 5 is limited by using the locking device on the slide block 402. The position of the spray cover 6 relative to the spray nozzle 601 can be controlled and the spray cover 6 is limited by adjusting the sliding assembly and the elastic assembly installed on the spray nozzle 601, and the area of the spray nozzle 601 can be constrained by adjusting the position of the spray cover 6. The spray range and the overlapping area at different positions in the water washing process of the carbon fiber precursor can be controlled by synchronously adjusting the spray ranges of a plurality of spray nozzles 601 on the carbon fiber precursor water washing equipment. By adjusting the spray range, the spray height, the water temperature and the spray pressure and the like, the tension of the carbon fiber precursor in the water washing process can be controlled in multiple dimensions, so as to reduce the occurrence of fuzzing and breaking of the carbon fiber precursor in the water washing process.

[0036] Compared with the prior art, the beneficial effects of the utility model are that the spray cover body controlled by the elastic assembly is additionally installed on the spray port, the spray range and the spray intensity of the spray port are constrained by adjusting the spray cover body, the flushing pressure caused by the overlapping spraying is reduced, the tension of the carbon fiber precursor in the water washing process is adjusted by controlling the spray cover bodies at different spraying positions in the water washing process, and the occurrence of fuzzing and breaking of the carbon fiber precursor is reduced.
