[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1-6 A preoxidation furnace for carbon fiber production is shown, including a preoxidation furnace body 1, a side end of the preoxidation furnace body 1 is fixedly connected with an outlet pipe 2, an end of the outlet pipe 2 away from the preoxidation furnace body 1 is provided with an outlet pipe 2 3, a filter plate 4 is slidably connected between the outlet pipe 2 and the outlet pipe 2 3, the upper end of the filter plate 4 is fixedly connected to the telescopic end of an electric push rod 5, the lower end of the outlet pipe 2 is sleeved with a collecting box 6, a pair of electric push rods 2 7 are fixedly connected to the inner bottom wall of the collecting box 6, and an electric push rod 3 8 is fixedly connected to the telescopic end of the electric push rod 2 7. Those skilled in the art can make the best choice of the models of the electric push rod 1 5, the electric push rod 2 7 and the electric push rod 3 8, such as ETS-10, a moving block 9 is fixedly connected to the telescopic end of the electric push rod 3 8, and the ends of the pair of moving blocks 9 close to each other are A scraper 10 is fixedly connected, a pair of limit blocks 21 are fixedly connected to the upper end of the collecting box 6, and the lower ends of the air outlet pipe 1 2 and the air outlet pipe 2 3 are provided with limit grooves 22 which are movably plugged with the limit blocks 21. After the limit blocks 21 are inserted into the limit grooves 22, the stability of the connection between the air outlet pipe 1 2 and the air outlet pipe 2 3 and the collecting box 6 can be improved. The upper end of the electric push rod 1 5 is fixedly connected to a fixed plate 11, and the side end of the pre-oxidation furnace body 1 is fixedly connected to the fixed plate 11, and a pair of arc blocks 12 are fixedly connected between the air outlet pipe 1 2 and the air outlet pipe 2 3. The side end of the pre-oxidation furnace body 1 is fixedly connected to a support frame 13, and the lower end of the collecting box 6 is fitted with the upper end of the support frame 13. The left and right ends of the collecting box 6 are fixedly connected with a transparent plate 15, and the transparent plate 15 is used to facilitate personnel to observe the status inside the collecting box 6.

[0025] The present invention can realize that when the gas enters the air outlet pipe 1 2, the dust in the gas is filtered by the filter plate 4. Finally, the filtered gas enters the outside through the air outlet pipe 2 3. After that, the personnel need to regularly clean the dust adhering to the filter plate 4. When cleaning the dust, the electric push rod 1 5 needs to be started to push the filter plate 4 downward. At the same time, the electric push rod 2 7 is started to move the scraper 10 to a certain height. When the filter plate 4 enters the collection box 6, the electric push rod 3 8 is started to move the scraper 10 toward the filter plate 4 until the scraper 10 and the filter plate 4 are fitted. Then, the electric push rod 2 7 is used to move the scraper 10 downward to scrape off the dust adhering to the filter plate 4. The scraped dust will fall into the collection box 6. Then, the collection box 6 is removed from the air outlet pipe 1 2 and the air outlet pipe 2 3, and the dust in the collection box 6 can be processed. Therefore, the furnace body can filter the dust in the gas and is convenient for personnel to collect and process the filtered dust.

[0026] The second implementation method:

[0027] Based on the first embodiment, this embodiment adds structures such as a water tank 16, and the rest of the parts are consistent with the first embodiment.

[0028] Figure 2 It is shown that a water tank 16 is provided at one end of the collecting box 6 away from the pre-oxidation furnace body 1, a micro spray pump is provided inside the water tank 16, a delivery pipe 17 is fixedly connected to one end of the water tank 16 close to the collecting box 6, the outer end of the delivery pipe 17 is fixedly connected to the inside of the collecting box 6, a nozzle 18 is fixedly connected to one end of the delivery pipe 17 away from the water tank 16, the nozzle 18 is plugged into the inside of the collecting box 6, a transparent plate 19 is fixedly connected to one end of the water tank 16 away from the delivery pipe 17, and the transparent plate 19 is used to facilitate personnel to observe the water amount in the water tank 16, a water pipe 20 is fixedly connected to the side end of the transparent plate 19, and a support plate 14 is fixedly connected to one end of the collecting box 6 away from the pre-oxidation furnace body 1, and the upper end of the support plate 14 is in contact with the lower end of the water tank 16.

[0029] This solution can be achieved. When the filter plate 4 is moved downward to scrape off the dust thereon, the micro spray pump needs to be started to spray the water in the water tank 16 from the nozzle 18 so that the water enters the collection box 6 and the filter plate 4, thereby achieving the purpose of dust reduction. This can prevent the dust from being dispersed to the outside when the dust is scraped off. At the same time, it can also prevent the dust from being inhaled by personnel when they are handling the dust in the collection box 6 due to the dust floating around.

[0030] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
