Description

Technical Field

[0001] The present invention relates to an intelligent regulating oxidation furnace, and more specifically to a plurality of devices of an intelligent regulating system of an oxidation furnace in an intelligent heat treatment production line for producing carbon fiber. Background Art

[0002] Carbon fiber is a fibrous carbon material with a carbon content of more than 90%. It is made by carbonizing various organic fibers under high temperature conditions of inert gas. With the increasing maturity of carbon fiber manufacturing technology, the current carbon fiber manufacturing process mostly includes two steps. The first step is to manufacture fiber precursors, and the second step is to pre-oxidize and carbonize the fiber precursors. Among them, the purpose of the pre-oxidation treatment is to convert the linear molecular chain of the fiber precursor into a heat-resistant ladder structure, so that it will not melt or burn during high-temperature carbonization, and maintain the fiber state.

[0003] Pre-oxidation is an intelligent key mechanical equipment of the entire production line. Its core function is not heating, but to quickly and efficiently remove a large amount of heat removed during the pre-oxidation of the precursor. If the heat is not removed in time, the fibers of the precursor will be concentrated with heat, resulting in fusion between the fibers, which will cause the subsequent carbonized fibers to become brittle and have poor performance; if the heat is accumulated more, the tow will catch fire, and improper handling may even cause the oxidation furnace to explode. This will bring huge losses of personnel and property. Therefore, it is necessary to circulate air in the oxidation furnace to preheat the carbon fiber precursor on the one hand, and to remove a large amount of heat generated by the oxidation reaction on the other hand to ensure the quality of carbon fiber molding. Some harmful substances will be generated during the oxidation process. Therefore, in order to prevent gas leakage in the pre-oxidation furnace and reduce the loss of temperature in the furnace, it is necessary to set a system that can adjust the size of the narrow slit opening online at the narrow slit device at both ends of the oxidation furnace to prevent gas leakage from the inlet and outlet at both ends of the furnace.

[0004] The ultimate goal of many existing narrow gap adjustment systems is to reduce the leakage of exhaust gas. The tow needs to pass through the entire oxidation furnace without contacting the oxidation furnace, but only contacting the reciprocating rollers at both ends of the oxidation furnace. In order to reduce the overflow of exhaust gas, the narrow gap should be closed as small as possible and will not contact the tow. The best state is to fine-tune the entire narrow gap opening to less than 8mm. However, most oxidation furnace narrow gap adjustment systems have some defects. First, due to debugging, oxidation furnace maintenance, etc., it is often necessary to adjust the size of the narrow gap opening. The inconvenience of adjustment will consume a lot of manpower and time. For example, some adjustment systems require manual adjustment of multiple adjustment rods or adjustment bolts, etc., which is not only inefficient each time, but also difficult to ensure the adjustment accuracy. Secondly, the tow may have different heights or be not in the center of the narrow gap. Correspondingly, the opening center height of the narrow gap adjustment system must also change accordingly, but most of the existing adjustment systems are cumbersome to adjust, and even cannot achieve this adjustment function. They can only adjust the height of the reciprocating roller outside the oxidation furnace to achieve this purpose, which also consumes a lot of manpower and time. In addition, after the raw silk is pulled to the oxidation furnace, when the machine is started, the tension of the tow will gradually increase until it reaches the tension required by the process. The change in tension will cause the tow to drape to change, so the opening size and height of the narrow slit will also change. Most existing oxidation furnaces have narrow slits that are first roughly adjusted to the position of the tow when the process tension is reached. When the actual tow height is inconsistent with the calculated height, the machine needs to be stopped and the opening size and height of the narrow slit need to be readjusted. The narrow slit cannot be easily adjusted online, which greatly affects the working efficiency and stability of the oxidation furnace. Finally, the structure of some adjustment systems still has the problem of long-term heat deformation. The adjustment system is twisted and deformed in the width of the tow, which will make the opening size of the narrow slit different. In order to accommodate the smallest opening, the opening of the narrow slit becomes larger, causing more waste gas to overflow, making it difficult to achieve our goal. Summary of the invention

[0005] In order to remedy the above defects, the present invention provides an intelligent adjustable oxidation furnace to solve the problems faced by the above background technology.

[0006] The intelligent adjustable oxidation furnace of the present invention comprises an adjusting system 1, which has a bilaterally symmetrical structure and is provided with an adjusting plate 1 in the entire width direction of the narrow slit opening. Specifically, the adjusting plate 1 is an L-shaped bent plate with a plurality of oblong holes formed on the plate body. A round tube is welded at one end of the bent plate, with a section of round steel extending from each end of the round tube, and the round steel extending out of the narrow slit.

[0007] Furthermore, each oblong hole on the adjusting plate 1 is provided with a compression spring, and the compression spring adjusts the elastic force through a bolt so that the adjusting plate 1 can be closely attached to the panel of the narrow slit without being completely locked and pressed.

[0008] Furthermore, at the top of the left and right sides of the narrow slit panel, there is a fixing seat, each with an oblong hole on the fixing seat, which is fixed to the narrow slit panel by locking bolts in the oblong hole. There is a support seat and an adjustment bolt under the fixing seat, the support seat is welded to the narrow slit panel, and the adjustment bolt passes through the fixing seat and the support seat. The bolts on the oblong holes of the fixing seat can be loosened, and the height of the fixing seat can be adjusted by using the adjustment bolts and the support seat.

[0009] Furthermore, a connecting rod mechanism is installed next to the fixing seat, and the connecting rod mechanism drives the two rods to rotate through the middle bearing, and the connecting rod mechanism is connected to the fixing seat through the bearing, so that when the fixing seat adjusts its height, the connecting rod structure can be driven to adjust its height together.

[0010] Furthermore, a column is connected to each of the two rods of the connecting rod mechanism, the inner column is close to the narrow slit, and the outer column is far away from the narrow slit, and the two columns are vertically downward through a limiter. Each layer of narrow slit has an upper adjustment plate 1 and a lower adjustment plate 1, and the round steels extending from both ends of the upper adjustment plate 1 are connected to the inner column connecting block, and the round steels extending from both ends of the lower adjustment plate 1 are connected to the outer column connecting block. The inner column connecting block is connected to the inner column with a fastener, and the outer column connecting block is connected to the outer column with a fastener. In this way, all the upper adjustment plates 1 of each layer of narrow slits are connected to the inner columns on the left and right sides of the narrow slit, and all the lower adjustment plates 1 of each layer of narrow slits are connected to the outer columns on the left and right sides of the narrow slit.

[0011] Furthermore, at the bottom of the left and right sides of the narrow slit panel, there is a screw lift with a handle. The lift is an intelligent key mechanical component of the adjustment system. The lift is fixed to the narrow slit panel. The left and right lifts are connected together by a driving rod to achieve common rotation and common adjustment of the screw height. At the top of the screw lift, the screw is close to the lift connection plate, and the outer column is supported on the lift connection plate.

[0012] When working, you can turn the screw lift with a handle, and the lifts on both sides will rise or fall together, driving the outer column to rise or fall. The outer column drives the inner column to fall or rise through the connecting rod mechanism at the top, so that the inner and outer columns move in opposite directions at the same time. The inner and outer columns each drive the upper adjustment plate 1 and the lower adjustment plate 1 of each layer of the narrow slit, so that the upper and lower adjustment plates 1 move in opposite directions, and the size of the opening of all narrow slits can be quickly adjusted. When the tow is not in the middle of the narrow slit, the adjustment bolt at the top of the narrow slit can be adjusted to make the left and right fixed seats rise or fall, so that the entire adjustment system can rise or fall to match the height of the tow. In addition, the screw lift is an intelligent universal component. In addition to the handle, it can also be connected to a motor to achieve the function of automatic adjustment.

[0013] The intelligent adjustable oxidation furnace of the present invention includes an adjustment system 2. The adjustment system 2 is bilaterally symmetrical in structure, and an adjustment plate 2 is provided in the entire width direction of the narrow slit opening. Specifically, the adjustment plate 2 is composed of a rotating round steel, an angle steel, and a clamping sleeve. A groove is provided on the rotating round steel, and one end of the angle steel is embedded and welded together. The clamping sleeve is inserted into the other end of the angle steel and fixed. The length of the angle steel and the clamping sleeve is consistent with the width of the narrow slit, and the length of the rotating round steel is greater than the width of the narrow slit. Both ends of the round steel extend out of the narrow slit. The parts used in the entire adjustment system are universal parts, and only a small amount is required for installation.

[0014] Furthermore, soft pads are installed at the positions corresponding to the rotating round steel on the panels above and below the narrow gap, so that the rotating round steel of the adjustment plate 2 is pressed onto the soft pads to prevent gas leakage at the upper and lower parts of the narrow gap.

[0015] Furthermore, in order to facilitate the rotation of the second adjustment plate, a rotating handle is connected to both ends of the rotating round steel, and the rotating handle is embedded in the round steel to provide a fulcrum for the rotation of the second adjustment plate.

[0016] Furthermore, a windshield is closely attached to both ends of the angle steel, the windshield is inserted between the upper and lower adjustment plates of the narrow slot, and is fixed with fasteners to prevent gas leakage from the side of the narrow slot.

[0017] Furthermore, a fixed shaft seat is installed on the panel of the narrow slot, and the fixed shaft seat has a handle bolt. The rotating round steel passes through the fixed shaft seat, and the entire adjusting plate 2 is fixed by relying on the fixed shaft seat.

[0018] During operation, the handle bolts on the fixed shaft seats at both ends can be loosened, and the rotating handle can be turned to drive the entire adjustment plate 2 to rotate. After the adjustment plate 2 rotates to the specified position, the handle bolts can be tightened to position the entire adjustment plate 2. This method can be used to rotate the two adjustment plates above and below the narrow slit to achieve the effect of opening and closing the narrow slit.

[0019] The invented intelligent regulating oxidation furnace includes regulating system 3. Specifically, the regulating plate 3 is a rectangular tube with a length equal to the width of the narrow slit.

[0020] Furthermore, soft cushions are installed on the panels above and below the narrow gap at positions corresponding to the windshield arc plates, so that the windshield arc plates of the adjustment plate three are pressed onto the soft cushions to prevent gas leakage above and below the narrow gap.

[0021] Furthermore, a glass windshield is closely attached to both ends of the working arc plate 1, and the windshield is inserted between the short circular tubes of the upper and lower adjustment plates 3 of the narrow gap to prevent gas leakage from the side of the narrow gap.

The pipe seat is fixed to the narrow slot panel by fasteners.

[0023] Furthermore, a silicone gasket is attached to the outside of the tube seat. When the short round tube of the adjustment plate three is inserted into the tube seat, the silicone cushion is also inserted together, so that the silicone cushion is squeezed onto the glass windshield, thereby fixing the glass windshield at this end of the column.

[0024] Further, the other end of the adjusting plate 3 is provided with a fixed shaft seat, and the short round tube at this end is inserted into the fixed shaft seat, and the whole adjusting plate 3 is fixed by the fixed shaft seat. In addition, a square plug is welded on the short round tube head at this end, and the square plug passes through the fixed shaft seat.

[0025] Furthermore, a compression spring is inserted into the fixed shaft seat near the third side of the adjustment plate. The compression spring is clamped between the fixed shaft seat and the glass windshield. The glass windshield is squeezed onto the working arc plate 1 of the adjustment plate 3, thereby fixing the glass windshield at this end of the column.

[0026] During operation, the fastening shaft bolt on the fixed shaft seat at one end can be loosened, and then the square plug at the main end can be clamped with a special wrench or an open-end wrench, and the square plug can be rotated to drive the entire adjustment plate three to rotate. Rotating the adjustment plate can not only quickly adjust the opening and closing of the narrow slit, but also the arc surface of the working arc plate one can be used to adjust the angle of the adjustment plate three according to the height of the wire bundle when the height of the wire bundle is different, so as to achieve the purpose of adjusting the height of the narrow slit opening. After the adjustment plate three is rotated to the specified position, the fastening shaft bolt is tightened to position the entire adjustment plate three. This method can not only adjust the size of the narrow slit opening, but also adjust the height of the narrow slit opening according to the height of the wire bundle.

[0027] The invented intelligent regulating oxidation furnace includes regulating system 4. Specifically, the main body of regulating plate 4 is a rectangular tube with a length equal to the width of the narrow slit. A long round tube is connected to one end of the rectangular tube close to the narrow slit panel. The long round tube is longer than the width of the narrow slit and extends out of the narrow slit.

[0029] Furthermore, a glass windshield is closely attached to both ends of the working arc plate 2, and the windshield is inserted between the long circular tubes of the upper and lower adjustment plates 4 of the narrow gap to prevent gas leakage from the side of the narrow gap.

[0030] Furthermore, a pipe seat is installed at one end of the adjusting plate 4, and the pipe seat is two sleeves connected together, and the long round tubes at the ends of the upper and lower adjusting plates of the narrow slot are inserted into the pipe seat to provide support. The pipe seat is fixed to the narrow slot panel by fasteners.

[0031] Furthermore, a silicone gasket is attached to the outside of the tube seat. When the long round tube of the adjusting plate 4 is inserted into the tube seat, the silicone cushion is also inserted together, so that the silicone cushion is squeezed onto the glass windshield, thereby fixing the glass windshield at this end of the column.

When the long round tube of the adjustment plate is inserted into the fixed tube seat, the silicone cushion is also inserted together, so that the silicone cushion is squeezed onto the glass windshield, thereby fixing the glass windshield at this end of the column.

[0034] During operation, the fastening shaft bolt on the fixed shaft seat at one end can be loosened, and then a special wrench or an open-end wrench can be used to clamp the square plug at the main end, and the square plug can be rotated to drive the entire adjustment plate four to rotate. Rotating the adjustment plate can not only quickly adjust the opening and closing of the narrow slit, but also use the arc surface of the working arc plate two to adjust the angle of the adjustment plate four according to the height of the wire bundle when the height of the wire bundle is different, so as to achieve the purpose of adjusting the height of the narrow slit opening. After the adjustment plate four is rotated to the specified position, the fastening shaft bolt is tightened to position the entire adjustment plate four.

Specifically, it is an intelligent adjustable oxidation furnace narrow gap adjustment system 39, and its adjustment plate 7 is bilaterally symmetrical, including an L-shaped bending plate with several oblong holes on the plate, a round tube welded on the plate, and a section of round steel extending from each end of the round tube, and the round steel extending out of the narrow gap. Each oblong hole is installed with a compression spring 12, and the elastic force is adjusted by bolts so that the adjustment plate 7 can be tightly attached to the panel of the narrow gap without being completely locked and pressed. At the top of the left and right sides of the narrow gap panel, there is a fixing seat 1, and the fixing seat 1 has an oblong hole on its body, which is fixed to the narrow gap panel by locking bolts on the oblong hole. There is a support seat 3 and an adjusting bolt 2 under the fixing seat 1, and the support seat 3 is welded to the narrow gap panel, and the adjusting bolt 2 passes through the fixing seat 1 and the support seat 3. The bolts on the oblong holes of the fixing seat 1 can be loosened, and the height of the fixing seat 1 can be adjusted by using the adjusting bolts 2 and the support seat 3. Next to the fixed seat 1, a connecting rod mechanism 4 is installed. The connecting rod mechanism 4 drives the two rods to rotate through the middle bearing, and the connecting rod mechanism 4 and the fixed seat 1 are connected together through the bearing. When the fixed seat 1 adjusts its height, it can drive the connecting rod mechanism 4 to adjust its height together. A column is connected to each of the two rods of the connecting rod mechanism 4. The inner column 6 is close to the narrow gap, and the outer column 5 is far away from the narrow gap. The two columns are vertically downward through a limiter. Each layer of the narrow gap has an upper adjustment plate 7 and a lower adjustment plate 7. The round steels extending from both ends of the upper adjustment plate 7 are connected to the inner column connection block 9, and the round steels extending from both ends of the lower adjustment plate 7 are connected to the outer column connection block 8. The inner column connection block 9 is connected to the inner column 6 with a fastener, and the outer column connection block 8 is connected to the outer column 5 with a fastener. In this way, all the upper adjustment plates 7 of each layer of narrow slits are connected to the inner columns 6 on the left and right sides of the narrow slits, and all the lower adjustment plates 7 of each layer of narrow slits are connected to the outer columns 5 on the left and right sides of the narrow slits. At the bottom of the left and right sides of the narrow slit panel, there is a screw elevator 10 with a handle, which is fixed to the narrow slit panel.

When working, the screw lift with a handle can be turned, and the lifts on both sides can be lifted or lowered together, driving the outer column 5 to rise or fall. The outer column 5 drives the inner column 6 to fall or rise through the connecting rod mechanism 4 at the top, so that the inner and outer columns move in opposite directions at the same time. The inner and outer columns respectively drive the upper adjustment plate 7 and the lower adjustment plate 7 of each layer of the narrow slit, so that the upper and lower adjustment plates 7 move in opposite directions, and the size of the opening of all narrow slits can be quickly adjusted. When the tow is not in the middle of the narrow slit, the adjustment bolt 2 at the top of the narrow slit can be adjusted to make the left and right fixed seats 1 rise or fall, so as to realize the rise or fall of the entire adjustment system 39 to match the height of the tow. In addition, the screw lift with a handle 10 can be connected to a motor, and an intelligent automatic control system can be used to achieve the function of automatic adjustment.The adjustment system makes the narrow gap adjustment more convenient and quick, does not need to consume a lot of manpower and time, and is simple and convenient to operate.

The length of the angle steel 20 and the sleeve 22 is consistent with the width of the narrow gap, while the length of the rotating round steel 14 is larger than the width of the narrow gap, and both ends of the rotating round steel 14 extend out of the narrow gap. Soft pads 21 are installed at the upper and lower panels of the narrow gap, corresponding to the rotating round steel 14, so that the rotating round steel 14 of the adjustment plate 23 is squeezed onto the soft pads 21 to prevent gas leakage at the upper and lower parts of the narrow gap. The soft pads 21 are made of silicone material, and the thickness should be moderate, which can provide sufficient friction without causing excessive pressure on the rotating round steel 14, resulting in difficulty in rotation. In order to facilitate the rotation of the adjustment plate 23, a rotating handle 17 is connected to both ends of the rotating round steel 14. The rotating handle 17 is embedded in the rotating round steel 14 to provide a fulcrum for the adjustment plate 23 to rotate. The design of the rotating handle 17 makes it fit tightly with the rotating round steel 14 to ensure that it will not loosen during the rotation process. A windshield 15 is tightly attached to both ends of the angle steel 20. The windshield 15 is inserted between the upper and lower adjustment plates 23 of the narrow gap and fixed with fasteners to prevent gas leakage from the side of the narrow gap. A fixed shaft seat 16 is installed on the panel of the narrow gap. The fixed shaft seat 16 has a handle bolt 18. The rotating round steel 14 passes through the fixed shaft seat 16 and relies on the fixed shaft seat 16 to fix the entire adjustment plate 23.

In this way, the opening size of the narrow slit can be adjusted quickly and accurately to achieve the purpose of adjusting the oxidation furnace. In addition, the design of the rotating round steel 14 and the angle steel 20 of the adjustment system 2 40 of the present invention makes the adjustment more stable and will not be deformed due to long-term heat exposure, thereby ensuring the use effect of the equipment. The parts used in the entire adjustment system 2 40 are all universal parts, which can be installed with only a small amount of processing, which is convenient for processing, manufacturing and installation.

The soft pad 21 is made of silicone material, and the thickness should be moderate, which can provide sufficient friction without causing excessive pressure on the adjustment plate three 27, resulting in difficulty in rotation. A glass windshield 25 is attached to both ends of the working arc plate 1 32. The glass windshield 25 is inserted between the short round tubes 31 of the upper and lower adjustment plates 3 27 of the narrow slit to prevent gas leakage from the side of the narrow slit. A pipe seat 26 is installed at one end of the adjustment plate 3 27. The pipe seat 26 is two sleeves connected together. A short round tube 31 at the end of the upper and lower adjustment plates 3 27 of the narrow slit is inserted into the pipe seat 26 to provide support. The pipe seat 26 is fixed to the narrow slit panel by fasteners. A silicone gasket 24 is attached to the outside of the pipe seat 26. When the short round tube 31 of the adjustment plate 3 27 is inserted into the pipe seat 26, the silicone gasket 24 is also inserted together, so that the silicone gasket 24 is squeezed onto the glass windshield 25, thereby fixing the glass windshield 25 at this end of the column.

[0058] Specific embodiment 4, refer to Figure 13 to Figure 17. Specifically, it is an intelligent regulating oxidation furnace narrow gap regulating system 42, whose regulating plate 434 includes a rectangular tube 33 as the main body, and the length of the rectangular tube 33 is equal to the width of the narrow gap. An elongated tube 38 is connected to one end of the rectangular tube 33 near the narrow gap panel, and the elongated tube 38 is longer than the width of the narrow gap and extends out of the narrow gap. A semicircle is cut in the middle of the elongated tube 38 at a position equal to the length of the rectangular tube 33, and then the rectangular tube 33 is embedded in the elongated tube 38 from this semicircle. Several triangular support plates 36 are welded to the other end of the rectangular tube 33. In addition, this end has a working arc plate 2 35 and an arc connecting plate 37, which are fixed to the rectangular tube 33 by fasteners. The length of the working arc plate 2 35 and the arc connecting plate 37 is the same as the width of the narrow gap. At the upper and lower panels of the narrow gap, at the position corresponding to the elongated tube 38, a soft pad 21 is installed, so that the elongated tube 38 of the regulating plate 434 is squeezed onto the soft pad 21 to prevent gas leakage at the upper and lower parts of the narrow gap. The cushion is made of silicone material, and the thickness should be moderate, which can provide sufficient friction without causing excessive pressure on the rotating long round tube 38, resulting in difficulty in rotation. A glass windshield 25 is closely attached to both ends of the working arc plate 2 35, and the glass windshield 25 is inserted between the long round tubes 38 of the upper and lower adjustment plates 4 34 of the narrow slit to prevent gas leakage from the side of the narrow slit. A pipe seat 26 is installed at one end of the adjustment plate 4 34. The pipe seat 26 is two sleeves connected together. The long round tubes 38 at the ends of the upper and lower adjustment plates 4 34 of the narrow slit are inserted into the pipe seat 26 to provide support. The pipe seat 26 is fixed to the narrow slit panel by fasteners. A silicone gasket 24 is attached to the outside of the pipe seat 26. When the long round tube 38 of the adjustment plate 4 34 is inserted into the pipe seat 26, the silicone gasket 24 is also inserted together, so that the silicone gasket 24 is squeezed onto the glass windshield 25, thereby fixing the glass windshield 25 at this end. A fixed shaft seat 16 is installed at the other end of the adjustment plate 434, and the long round tube 38 at this end is inserted into the fixed shaft seat 16, and the entire adjustment plate 434 is fixed by the fixed shaft seat 16. In addition, a square plug 29 is welded on the head of the long round tube 38 at this end, and the square plug 29 passes through the fixed shaft seat 16. A silicone gasket 24 is also attached to the side of the fixed shaft seat 16 close to the adjustment plate 434. When the long round tube 38 of the adjustment plate 434 is inserted into the fixed shaft seat 16, the silicone gasket 24 is also inserted together, so that the silicone gasket 24 is squeezed onto the glass windshield 25, thereby fixing the glass windshield 25 at this end. During operation, the fastening shaft bolt on the fixed shaft seat 16 at one end can be loosened, and then the square plug 29 at the main end can be clamped with a special wrench or an open-end wrench, and the square plug 29 can be rotated to drive the entire adjustment plate 4 34 to rotate. Rotating the adjustment plate can not only quickly adjust the opening and closing of the narrow slit, but also use the arc surface of the working arc plate 2 35 to adjust the angle of the adjustment plate 4 34 according to the height of the wire bundle when the height of the wire bundle is different, so as to achieve the purpose of adjusting the height of the narrow slit opening. After the adjustment plate 4 34 is rotated to the specified position, the fastening shaft bolt is tightened to position the entire adjustment plate 4 34.This method can not only quickly adjust the size of the narrow slit opening, but also adjust the height of the narrow slit opening according to the height of the yarn bundle. Moreover, even when the production line is running, the function of online rapid adjustment can be achieved.
