Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber, and more specifically, to a low-temperature carbonization furnace for producing continuous carbon fiber. Background Art

[0002] Carbon fiber refers to a high-strength and high-modulus fiber with a carbon content of more than 90%. It is made from acrylic fiber and viscose fiber as raw materials, and is formed by high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment such as aerospace. The composite material composed of carbon fiber and epoxy resin has the highest comprehensive index of specific strength and specific modulus among existing structural materials. In fields with strict requirements for density, stiffness, weight, fatigue characteristics, etc., and in occasions requiring high temperature and high chemical stability, carbon fiber composite materials have great advantages.

[0003] In the production process of carbon fiber, as the temperature in the carbonization furnace hearth gradually rises, the carbon fiber will gradually react and release harmful gases, which mainly include carbon monoxide, carbon dioxide, nitrogen oxides, and some incompletely burned hydrocarbon compounds. However, currently, the exhaust gas emission system of the carbonization furnace is usually limited to allowing the exhaust gas to naturally disperse by opening the furnace lid. This method is not only inefficient but also easily causes the exhaust gas to accumulate in the furnace and adhere to the furnace hearth wall. Long-term accumulation will cause tar to deposit on the inner wall of the furnace hearth. Once it reaches a certain level, the tar will drip, thereby polluting the fiber and affecting its performance. Summary of the Invention

The plurality of pipes 34 fixedly connected to the top of the air extraction plate 33 extend to the inner wall of the waste gas purification assembly 35; When carbon fiber needs to be put into the carbonization furnace 23, first start the second motor 123, so that the output end of the second motor 123 drives the third turntable 124 to rotate. Then, the third turntable 124 drives the fourth turntable 126 to rotate through the second crawler 125. The rotation of the fourth turntable 126 causes the second columnar rotating rod 127 to rotate. The rotation of the second columnar rotating rod 127 causes the two fifth turntables 129 to rotate. The rotation of the two fifth turntables 129 drives the two sixth turntables 1212 to rotate respectively through the two third crawlers 1211. The rotation of the two sixth turntables 1212 causes the two rotating rods 1214 to move. The movement of the two rotating rods 1214 pulls the two second rotating rods 213 to rotate respectively through the two columnar internal connecting rods 1215. The rotation of the two second rotating rods 213 causes the two L-shaped cover connecting rods 212 to rotate. The rotation of the two L-shaped cover connecting rods 212 causes the arc-shaped cover 214 to open, and then the carbonization furnace feeding port 24 is exposed. At this time, carbon fiber can be put into the carbonization furnace 23. After the carbon fiber is put into the carbonization furnace 23, start the second motor 123 in the opposite direction. At this time, the arc-shaped cover 214 resets to close the carbonization furnace feeding port 24; The carbon fiber in the carbonization furnace 23 is subjected to low-temperature carbonization treatment by the electromagnetic heating tray 22. The electromagnetic heating tray 22 converts electrical energy into heat energy through the principle of electromagnetic induction to uniformly heat the carbonization furnace 23. During the heating process, the carbon fiber in the carbonization furnace 23 gradually undergoes a carbonization reaction to generate continuous carbon fiber. At the same time, in order to control the temperature of the carbonization process, the temperature of the electromagnetic heating tray 22 can be precisely controlled by adjusting the intensity of electromagnetic induction to ensure the stability and controllability of the carbonization process; When the waste gas in the carbonization furnace 23 reaches a certain amount, at this time, start the motor 113, so that the output end of the motor 113 drives the turntable 116 to rotate. The rotation of the turntable 116 will cause the crawler 117 to move. The movement of the crawler 117 will cause the second turntable 118 to rotate. The rotation of the second turntable 118 will cause the columnar rotating rod 114 to rotate. The rotation of the columnar rotating rod 114 will cause the conical rotating block 115 to rotate. The rotation of the conical rotating block 115 will cause the runner 211 to slide along the outer wall of the conical rotating block 115, thereby pushing the whole low-temperature carbonization furnace 2 towards the inner wall of the waste gas discharge bin 3. The two side guide plates 28 slide along the outer wall of the columnar guide rod 119, and the bottom of the low-temperature carbonization furnace 2 slides on the tops of the two sliding pallets 1110. When the low-temperature carbonization furnace 2 slides towards the inner wall of the waste gas discharge bin 3, at this time, since the second motor 123 is not started, the two rotating rods 1214 and the columnar inner connecting rod 1215 inside them are fixed. Therefore, when the whole low-temperature carbonization furnace 2 moves towards the inner wall of the waste gas discharge bin 3, at this time, the two second rotating rods 213 will pull the two L-shaped cover connecting rods 212 to rotate along the inner wall of the hinge block 25. The rotation of the two L-shaped cover connecting rods 212 will open the arc-shaped cover 214, thereby exposing the carbonization furnace discharge port 24. At this time, the waste gas generated in the carbonization furnace 23 will be discharged into the waste gas discharge bin 3 through the carbonization furnace discharge port 24. The air extraction plate 33 in the waste gas discharge bin 3 is started to extract the waste gas, and the waste gas is inhaled into the waste gas purification component 35 through multiple pipes 34 for purification treatment to avoid environmental pollution caused by harmful substances in the waste gas. When the whole low-temperature carbonization furnace 2 moves to the inner wall of the waste gas discharge bin 3, at this time, the outer wall of the conical rotating block 115 just fits with the outer wall of the runner 211. At this time, turn off the motor 113 to stop pushing the low-temperature carbonization furnace 2.

[0021] Working principle of the present invention: When carbon fiber needs to be put into the carbonization furnace 23, first start the second motor 123, so that the output end of the second motor 123 drives the third turntable 124 to rotate. Then, the third turntable 124 drives the fourth turntable 126 to rotate through the second track 125. The rotation of the fourth turntable 126 causes the second columnar rotating rod 127 to rotate. The rotation of the second columnar rotating rod 127 causes the two fifth turntables 129 to rotate. The rotation of the two fifth turntables 129 drives the two sixth turntables 1212 to rotate respectively through the two third tracks 1211. The rotation of the two sixth turntables 1212 causes the two rotating rods 1214 to move. The movement of the two rotating rods 1214 pulls the two second rotating rods 213 to rotate respectively through the two columnar inner connecting rods 1215. The rotation of the two second rotating rods 213 causes the two L-shaped cover connecting rods 212 to rotate. The rotation of the two L-shaped cover connecting rods 212 causes the arc-shaped cover 214 to open, and then the carbonization furnace feeding port 24 is exposed. At this time, carbon fiber can be put into the carbonization furnace 23. After the carbon fiber is put into the carbonization furnace 23, start the second motor 123 in the reverse direction. At this time, the arc-shaped cover 214 resets to close the carbonization furnace feeding port 24. The carbon fiber in the carbonization furnace 23 is subjected to low-temperature carbonization treatment by the electromagnetic heating tray 22. The electromagnetic heating tray 22 converts electrical energy into heat energy through the principle of electromagnetic induction to uniformly heat the carbonization furnace 23. When the waste gas in the carbonization furnace 23 reaches a certain amount, at this time, start the motor 113, so that the output end of the motor 113 drives the turntable 116 to rotate. The rotation of the turntable 116 causes the track 117 to move. The movement of the track 117 causes the second turntable 118 to rotate. The rotation of the second turntable 118 causes the columnar rotating rod 114 to rotate. The rotation of the columnar rotating rod 114 causes the conical rotating block 115 to rotate. The rotation of the conical rotating block 115 causes the runner 211 to slide along the outer wall of the conical rotating block 115, and then pushes the whole low-temperature carbonization furnace 2 towards the inner wall of the waste gas discharge chamber 3. The two side guide plates 28 slide along the outer wall of the columnar guide rod 119. The bottom of the low-temperature carbonization furnace 2 slides on the tops of the two sliding trays 1110. When the low-temperature carbonization furnace 2 slides towards the inner wall of the waste gas discharge chamber 3, at this time, since the second motor 123 is not started, the two rotating rods 1214 and the columnar inner connecting rods 1215 inside them are fixed. Therefore, when the whole low-temperature carbonization furnace 2 moves towards the inner wall of the waste gas discharge chamber 3, at this time, the two second rotating rods 213 pull the two L-shaped cover connecting rods 212 to rotate along the inner wall of the hinge block 25. The rotation of the two L-shaped cover connecting rods 212 causes the arc-shaped cover 214 to open, and then the carbonization furnace feeding port 24 is exposed. At this time, the waste gas generated in the carbonization furnace 23 is discharged into the waste gas discharge chamber 3 through the carbonization furnace feeding port 24. The air extraction plate 33 in the waste gas discharge chamber 3 is started to extract the waste gas, and the waste gas is sucked into the waste gas purification component 35 through multiple pipes 34 for purification treatment to avoid environmental pollution caused by harmful substances in the waste gas.When the whole low-temperature carbonization furnace 2 is moved to the inner wall of the waste gas discharge bin 3, at this time, the outer wall of the conical rotating block 115 just fits with the outer wall of the rotating wheel 211. At this time, the motor 113 is turned off to stop the pushing of the low-temperature carbonization furnace 2.
