[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] Example 1

[0024] like Figures 1-5 As shown, an exhaust device for a carbon fiber oxidation furnace includes: a housing 3 having an air inlet and an air outlet, wherein an air inlet pipe 18 is installed at the air inlet and an air outlet pipe 8 is installed at the air outlet; a plurality of filter screens 11 disposed inside the housing 3 and arranged sequentially along the gas flow path; a support assembly for installing the filter screens 11 inside the housing 3; an elastic assembly for pushing the filter screens 11 out of the housing 3; and a limiting assembly for limiting the elastic assembly.

[0025] The housing 3 is equipped with a cover plate 6, and the housing 3 and the cover plate 6 are connected by an adsorption assembly. The adsorption assembly includes a first magnetic block 4 disposed on the housing 3 and a second magnetic block 5 disposed on the cover plate 6, and the first magnetic block 4 and the second magnetic block 5 are magnetically coupled together. The adsorption assembly adsorbs and fixes the cover plate 6, thereby preventing the cover plate 6 from moving and causing gas leakage inside the housing 3, and improving the stability of the cover plate in sealing the housing.

[0026] The support assembly includes a slider 17 connected to the filter screen 11 and a groove 10 disposed on the inner wall of the housing 3. The slider 17 and the groove 10 are slidably connected. In this embodiment, there are two filter screens 11, and sliders 17 are welded to the two side frames of each filter screen 11. A groove 10 for installing the filter screen 11 is provided on a set of opposite side walls of the housing 3.

[0027] The elastic component includes a spring 14 and a slip ring 16 disposed within the slide groove 10; one end of the spring 14 is connected to the bottom of the slide groove 10, and the other end is connected to the slip ring 16; when the filter screen 11 is installed inside the housing 3, the slip ring 16 abuts against the surface of the slider 17. A guide rod 13 is also disposed within the slide groove 10, passing through the slip ring 16 and inserting into the slider 17. The guide rod 13 is used to guide the movement of the spring 14 and the slip ring 16, improving the stability of their movement.

[0028] The limiting assembly includes an L-shaped plate 7 mounted on the housing 3, a threaded rod 12 rotatably connected to the L-shaped plate 7, an insert rod 15 for limiting the slider 17, and a fixing rod 9 connected to the L-shaped plate 7. The insert rod 15 is threadedly connected to the threaded rod 12. The insert rod 15 is slidably connected to the fixing rod 9. A knob for rotating the threaded rod 12 is welded to one end of the threaded rod 12. The knob has multiple anti-slip grooves on its outer side, which are evenly distributed and increase the force driving the threaded rod 12. The limiting assembly can stop the slider, thereby ensuring stable placement of the filter screen inside the housing, preventing the filter screen from moving, and improving the stability of the filter screen installation.

[0029] Working principle: When the filter screen 11 needs to be disassembled and cleaned, pull the cover plate 6 upward. The cover plate 6 will drive the second magnetic block 5 upward, causing the second magnetic block 5 to disengage from the first magnetic block 4, thereby opening the housing 3. Then, turn the threaded rod 12 by turning the knob. The threaded rod 12 will drive the insertion rod 15 to move along the fixed rod 9, so that the insertion rod 15 no longer blocks the slider 17. At this time, the spring 14 will push the slip ring 16 upward along the guide rod 13. The slip ring 16 will push the slider 17 upward along the slide groove 10. The slider 17 will move the filter screen 11 upward, thereby pushing the filter screen 11 out of the housing 3, realizing the disassembly and cleaning of the filter screen 11, avoiding the filter screen 11 from clogging and affecting its use, and improving the use effect of the exhaust device. After the filter screen 11 is cleaned, install the filter screen 11 in the reverse process. First, insert slider 17 into slide groove 10 and press down filter screen 11. At this time, slider 17 pushes slide ring 16 along guide rod 13 to compress spring 14 within slide groove 10. When filter screen 11 reaches the set position, rotate threaded rod 12 in the opposite direction using knob. Threaded rod 12 will drive insertion rod 15 to move along fixed rod 9, causing insertion rod 15 to block slider 17. Then, release filter screen 11 and place cover plate 6 on housing 3. This completes the process of disassembling, cleaning, and resetting filter screen 11.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
