Description

Technical Field

[0001] This invention relates to the field of carbonized felt production technology, specifically to a carbonization equipment for producing carbonized felt. Background Technology

[0002] Against the backdrop of accelerated global energy transformation, the new energy and new materials industries have ushered in a new window of opportunity for development. With the current strong momentum of new energy development, the role and value of carbon felt are increasing daily. Carbon fiber materials have excellent heat resistance, withstanding temperatures above 1000 degrees Celsius in inert gases and an ignition point as high as 500 degrees Celsius in air. Therefore, many manufacturers in industry use carbon felt as insulation material for the inner walls of high-temperature furnaces, wrapping the furnace walls.

[0003] Carbonized felt is produced by sending raw materials into carbonization equipment for high-temperature carbonization. After carbonization, the carbonized felt needs to be cooled to room temperature. During carbonization, the oxygen content in the furnace needs to be strictly controlled. After carbonization, opening the furnace lid to dissipate heat can cause the felt to continue reacting with oxygen at high temperatures, affecting the quality of the finished product. However, if the furnace lid is not opened and the furnace is in a closed state, the high temperature of the carbonization furnace will result in a long heat dissipation time, which not only wastes the time of the staff but also greatly reduces work efficiency and is inconvenient to use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a carbonization equipment for producing carbonized felt, which solves the problem of low cooling efficiency in existing carbonization equipment.

[0013] Beneficial effects

[0014] This invention discloses a carbonization equipment for producing carbonized felt, which has the following beneficial effects: The device has a compact structure. By setting up a split carbonization furnace, the inner and outer furnace bodies are combined during heating, and the heating effect is ensured by the heat insulation layer. When cooling is required, the outer furnace body is moved by the drive mechanism to separate from the inner furnace body, which can effectively improve the cooling efficiency in the closed state. At the same time, the high-heat exhaust gas generated during the heating process is heat exchanged in the heat exchange chamber, and the hot gas is blown into the drying box by the blower and the air distribution plate to dry the material and realize heat recovery. Meanwhile, during the flow of gas in the transmission housing, it will drive the blades to rotate, and then the rotating shaft will drive the stirring rods at both ends to rotate, realizing the stirring of the material and improving the drying effect. The exhaust gas after heat exchange enters the gas purification device, and after purification, it flows back into the annular pipe and is blown into the inner furnace body by the jet nozzle, further improving the cooling efficiency and bringing convenience to people's use.

The transmission housing 15 is provided with a stirring mechanism. The output end of the gas purification device 17 is connected to the heat dissipation mechanism through the return pipe 18. The heat dissipation mechanism is fixedly provided above the base 1. The base 1 is also provided with a drive mechanism connected to the outer furnace body 4.

[0020] In this embodiment, the driving mechanism is further configured such that the sliding mechanism includes a slide groove 19 disposed on the upper wall of the base 1, a slider 20 disposed in the slide groove 19, the upper wall of the slider 20 being fixedly connected to the outer furnace body 4 via a slide frame 21, an electric push rod 22 disposed on one side of the upper wall of the base 1, the telescopic end of the electric push rod 22 being connected to the slide frame 21, a fixing ring 23 disposed on the outer wall of the inner furnace body 3, a plurality of guide rods 24 disposed on the side wall of the fixing ring 23 along the circumferential direction, and a guide hole matching the guide rods 24 disposed in the inner furnace body 4.

[0021] In this embodiment, the stirring mechanism is further configured such that the stirring mechanism includes a rotating shaft 25 rotatably installed in the transmission housing 15, the two ends of the rotating shaft 25 penetrate the transmission housing 15 and are fixedly installed with a plurality of stirring rods 26, and a plurality of transmission blades 27 are fixedly installed at the center of the rotating shaft 25.

[0022] In this embodiment, the heat dissipation mechanism includes a plurality of annular tubes 28 fitted on the outside of the outer furnace body 4. The plurality of annular tubes 28 are connected to each other by connecting pipes 29. The annular tube 28 near the furnace cover 5 is connected to the return pipe 18. The inner wall of the annular tube 28 is provided with a plurality of jet nozzles 30 along the circumferential direction.

[0023] In this embodiment, a pipe rack 31 for supporting the annular pipe 28 is fixedly provided above the base 1.

[0024] In this embodiment, the gas supply pipe 16 is further configured to be equipped with a circulating fan 32.

[0026] In this embodiment, the drying box 10 is further configured such that a feed inlet is provided at the top and a discharge outlet is provided at the bottom.

[0027] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0028] Example: During operation, the pre-oxidized felt is placed in the placement rack 8 of the inner furnace body 3. The material is carbonized at high temperature by the heating component 7. The generated high-temperature exhaust gas can enter the heat exchange tube 13 through the exhaust pipe 9. During the flow of the heat exchange tube 13 in the heat exchange chamber 12, the blower 14 is started, so that the airflow comes into contact with the heat exchange tube 13 to exchange heat and form hot gas. Finally, it is blown into the drying box 10 by the air distribution plate to dry the raw material of the carbonized felt. Heat exchange chambers 12 are set on both sides of the drying box 10 to ensure the heat exchange effect. At the same time, when the high-temperature exhaust gas flows through the transmission shell 15, since the transmission shell 15 is located below the heat exchange tube 13, the high-temperature exhaust gas will drive the transmission blade 27 to rotate, and then the rotating shaft 25 will drive the stirring rod 26 to rotate, stirring the material and improving the drying effect. The exhaust gas after heat exchange enters the gas purification device 17 through the gas delivery pipe 16 for filtration and purification. In order to ensure the gas flow effect, multiple circulation pumps can be added to the pipeline.

[0029] When cooling is required after carbonization, the electric push rod 22 drives the slide 21 to slide horizontally, thereby separating the outer furnace body 4 from the inner furnace body 3, so that the inner furnace body 3 is directly exposed to the room, improving the cooling efficiency. At the same time, the purified gas can be transported to the annular pipe 28 through the return pipe 18 and sprayed out through the jet nozzle 30 to assist in cooling, further improving the cooling efficiency and making it convenient to use.
