At the same time, the first positioning block 831 and the second positioning block 841 can slightly push the feed valve 81 downward during installation, so that the bottom of the sealing sleeve 89 provided on the outside of the feed valve 81 is tightly fitted with the installation disk 10 provided above, so as to prevent the leakage of the carbon fiber raw material.

[0043] Working process: When the carbon fiber spinning pretreatment device is used, first, the device is fixed in a suitable position by the fixed shaft 3, and then the discharge valve 12 and the feed valve 81 are connected through a pipeline. At this time, the carbon fiber raw material is sent into the feed valve 81 through the pipeline. At this time, the feed valve 81 is opened, and the material enters the guide pipe 13 through the feed valve 81. The guide pipe 13 sends the material into the filter sleeve 66. At this time, the material passes through the filter sleeve 66 and enters the fixed shell 61. The material in the fixed shell 61 enters through the insert pipe 725. The material passes through the lower connecting shell 722 and the insert tube 725 into the filter sleeve 66 for secondary filtration. The material after secondary filtration passes through the lower guide tube 13 and enters the discharge valve 12. At this time, the discharge valve 12 is opened, and the filtered material is sent out through the discharge valve 12 and the pipeline to realize the pretreatment of the carbon fiber spinning raw material. When there are too many impurities in the filter screen and it needs to be replaced, please refer to Figure 11-16, first close the feed valve 81, press the push plate 87, the push plate 87 drives the separation plate 88 to move downward, the separation plate 88 pushes the first upper positioning plate 834 and the second upper positioning plate 844 to move through the arc setting at the bottom, at this time the spring 836 set in the second upper positioning plate 844 moves to a suitable position, at this time the first upper positioning plate 834 and the second upper positioning plate 844 respectively drive the first positioning block 831 and the second positioning block 841 to move outside the limit plate 82, the second positioning block 841 drives the plug plate 843, the second upper positioning plate 844 and the second lower positioning plate 845 to move, and then moves the first positioning block 831 and the second positioning block 841 to both sides, the first positioning block 831 and the second positioning block 841 drive the first upper positioning plate 834 and the second upper positioning plate 845 to move. 844, the first lower positioning plate 835 and the second lower positioning plate 845 are moved, and then the first positioning block 831 and the second positioning block 841 are removed from the outside of the limiting plate 82, and at the same time, the first upper positioning plate 834, the second upper positioning plate 844, the first lower positioning plate 835 and the second lower positioning plate 845 are removed from the card slot 86 opened by the card block 85.
