[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that, in the absence of conflict, the embodiments in this application and the feature vectors in the embodiments can be arbitrarily combined with each other.
[0031] In the related art, the existing drying section is usually set up parallel to the horizontal plane. Since there is a sizing agent on the fiber, waste gas will be generated during the drying process of the fiber 7, and the waste gas is easy to gather in the drying section 1 and condense and drip, and is not easy to disperse, which will affect the quality of the fiber 7 after drying. In the process of sizing the sizing fiber sizing drying device treating the carbon fiber, since the sizing agent on the carbon fiber is not thoroughly dried, the carbon fiber tow will be stuck and difficult to defilament during use, and the waste gas generated will gather in the furnace, affecting the subsequent performance of the carbon fiber, and with the increase of waste gas, it is easy to cause safety hazards.
[0032] In order to solve the problems existing in the related art, an embodiment of the present application provides a fiber sizing and drying device. The fiber sizing and drying device includes a drying section, which is used to define a drying chamber, in which fibers are dried, wherein the drying section is inclined, and the drying section has an inlet end and an outlet end, and the height of the inlet end is higher than the height of the outlet end. In the present application, the drying section is inclined, and the drying section has an inlet end and an outlet end, and the height of the inlet end is higher than the height of the outlet end, so as to prevent the exhaust gas from condensing in the drying section and dripping on the fibers, and the inclined drying section is also conducive to the rapid discharge of the internal exhaust gas to ensure the quality of the fibers after drying.
[0033] In order to make the purpose, technical solution and beneficial effects of the embodiment of the present application clearer, a fiber sizing and drying device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0034] According to the disclosed exemplary embodiments, Figure 1 and Figure 2 As shown, a fiber sizing and drying device is shown, which is used to dry fiber 7. Fiber 7 can be man-made fiber, synthetic carbon fiber and other materials. In this application, fiber 7 can be carbon fiber. It should be noted that in order to obtain better fiber 7, the fiber raw silk needs to be made into fiber 7 through sizing, drying and other processes, wherein the drying process can improve the strength and hardness of fiber 7, thereby preparing fiber 7 that meets the use requirements.
[0035] The fiber sizing and drying device includes a drying section 1, which is used to dry the fibers 7 impregnated with the sizing agent. The drying section 1 is used to define a drying chamber 11, and the fibers 7 are located in the drying chamber 11, wherein the drying section 1 can be a drying box, a drying furnace, a heating tank, etc., as long as it can dry the fibers 7. The drying section 1 also has an inlet end 12 and an outlet end 13. The drying section 1 in the present application is inclined relative to the horizontal plane 8, so that the inlet end 12 and the outlet end 13 of the drying section 1 are located at different heights. For example, the height of the inlet end 12 is higher than the height of the outlet end 13. The hot air generated in the drying section 1 can flow from the outlet end 13 to the inlet end 12, and as the temperature in the drying section 1 increases, the exhaust gas can be quickly discharged to avoid the exhaust gas from accumulating in the drying section 1, so as to ensure the quality of the subsequent fibers 7.
[0036] In one example, continue to refer to Figure 1 The inlet end 12 and the outlet end 13 of the drying section 1 are both provided with rollers 100 . The number and arrangement of the rollers 100 can be adaptively arranged as required. In this regard, there are no excessive restrictions in the present application. The rollers 100 are used to support or pull the fibers 7 .
[0037] In some embodiments, Figure 1 to Figure 2As shown, there is a preset angle between the line connecting the inlet end 12 and the outlet end 13 and the horizontal plane 8, and the preset angle is 1° to 60°. Figure 1 to Figure 2 The preset angle between the line connecting the inlet end 12 and the outlet end 13 of the drying section 1 and the horizontal plane 8 is 15°. When drying the fiber 7, the hot air generated by the drying section 1 rises and flows from the outlet end 13 to the inlet end 12, thereby reducing the drying time of the fiber 7.
[0038] In some embodiments, the drying section 1 is provided with a plurality of baffles, and the shape and structure of the baffles can be adaptively set as required. This application will not go into detail. The baffles are used to block the heat in the drying chamber 11 of the drying section 1 to prevent it from being lost, so that the heat is gathered in the space formed by the plurality of baffles and the drying chamber 11. In one example, Figure 1 and Figure 2 As shown, a first baffle 2 is provided at the inlet end 12 of the drying section 1, and a second baffle 3 is provided at the outlet end 13 of the drying section 1. A first channel is formed between the first baffle 2 and the top wall of the inlet end 12, and a second channel is formed between the second baffle 3 and the bottom wall of the outlet end 13. Both the first channel and the second channel are connected to the drying chamber 11. The fiber 7 enters the drying chamber 11 through the first channel and passes out of the drying chamber 11 through the second channel, so that when the fiber 7 is drying, the sizing agent or the fiber 7 covering the surface is not scratched by the first baffle 2 and the second baffle 3, thereby ensuring the strength of the fiber 7 after drying.
[0039] In some embodiments, the size of the first channel is 10 mm to 20 mm, and the size of the second channel is 10 mm to 20 mm. In one example, the sizes of the first channel and the second channel are both 15 mm, so as to reduce the heat loss in the drying chamber 11 of the drying section 1, thereby effectively drying the fiber 7, and also ensuring that the fiber 7 is not scratched when entering the drying section 1.
[0040] In some embodiments, the drying section 1 includes a drying furnace 10. Along the extension direction of the drying furnace 10, a plurality of heating tubes 14 are evenly arranged on the top wall and the bottom wall of the drying furnace 10. The number of heating tubes 14 can be eight, sixteen, etc. The number of heating tubes 14 can be adaptively set as needed. Figure 1 and Figure 2 As shown, the temperature of the multiple heating tubes 14 reaches 230°C. The heating tubes 14 are arranged on the upper and lower inner walls of the drying furnace 10 and are evenly arranged along the extension direction of the drying furnace 10, so that the fibers 7 in the drying chamber 11 are thermally balanced, thereby enhancing the performance of the fibers 7 after drying.
[0041] It should be noted that the temperature of the heating tube 14 is not the one mentioned above. For example, different temperatures can be adjusted to dry the fibers 7 according to the material of the fibers 7 required.
[0042] In some embodiments, Figure 1 and Figure 2 As shown, the fiber sizing and drying device also includes a waste gas treatment part 4, which is used to treat the waste gas. The waste gas treatment part 4 includes a waste gas collecting channel 41 and a waste gas treatment pool 42, wherein the inlet end 12 and the outlet end 13 of the drying part 1 are both connected to the first end 411 of the waste gas collecting channel 41, and the waste gas treatment pool 42 is connected to the second end 412 of the waste gas collecting channel 41, so that the waste gas in the drying part 1 can be transported to the waste gas treatment pool 42 through the waste gas collecting channel 41, thereby reducing the concentration of the waste gas discharged into the air, so that the waste gas can be effectively treated.
[0043] In some embodiments, continue to refer to Figure 1 The first end 411 of the exhaust gas collecting channel 41 is provided with an exhaust valve 9, which is used to exhaust the gas or liquid in the system, and the exhaust valve 9 controls the speed and pressure of the gas or liquid flow in the system by opening or closing to ensure stability and safety. Figure 1 As shown, the exhaust valves 9 are respectively installed on the exhaust gas collecting channel 41 near the inlet end 12 and the outlet end 13. The exhaust valves 9 are used to discharge the exhaust gas generated in the drying section 1. By adjusting the exhaust valves 9, the exhaust gas collection and discharge speeds at the inlet end 12 and the outlet end 13 of the drying section 1 can be regulated.
[0044] In some possible embodiments, Figure 1 and Figure 2 As shown, a fan 6 is arranged between the first end 411 of the exhaust gas collecting channel 41 and the second end 412 of the exhaust gas collecting channel 41. The fan 6 is used to suck the exhaust gas generated by the drying section 1 into the exhaust gas treatment tank 42. When the fiber sizing and drying device is working, the exhaust gas can be quickly gathered and sucked into the exhaust gas treatment tank 42 to prevent the exhaust gas from flowing out to the outside and causing environmental pollution.
[0045] In some embodiments, the shape and structure of the waste gas treatment pool 42 are adaptively set as needed. Figure 1 As shown, the waste gas treatment pool 42 is box-shaped and defines a waste gas treatment chamber 421, wherein the waste gas treatment chamber 421 contains water 422, and the waste gas is placed below the liquid level of the water 422. It should be noted that the water 422 is the use of water resources, and the water 422 can be industrial water, production water, domestic water, etc. In this application, it is industrial water, and 0.2% of oil removal additives are added to the industrial water. The oil removal additives are used to dilute or decompose the waste gas. The industrial water in the waste gas treatment pool 42 can not only effectively absorb the waste gas generated in the drying section 1, but also reduce the waste gas emission concentration.
[0046] In some embodiments, Figure 1As shown, the waste gas treatment pool 42 includes an exhaust channel 43, and the exhaust channel 43 is arranged at the top of the waste gas treatment pool 42 away from the drying section 1. The exhaust channel 43 is connected to the waste gas treatment pool 42. The exhaust channel 43 is used to discharge the treated waste gas through the waste gas treatment pool 42, that is, the waste gas generated by the drying section 1 is decomposed and treated by the waste gas treatment pool 42 to reduce the concentration, and then discharged through the exhaust channel 43.
[0047] The waste gas treatment pool 42 includes a water replenishment channel 44, which is arranged at one side of the waste gas treatment pool 42 away from the drying part 1, and the water replenishment channel 44 is connected to the waste gas treatment pool 42. The staff can replenish the water 422 in the waste gas treatment chamber 421 through the water replenishment channel 44. The waste gas treatment pool 42 also includes a drainage channel 45, which is arranged at the bottom of the waste gas treatment pool 42 away from the drying part 1, and the drainage channel 45 is connected to the waste gas treatment pool 42. When the water 422 in the waste gas treatment chamber 421 decomposes or dilutes the waste gas, Afterwards, too much residue is left in the waste gas treatment chamber 421 and mixed with the water 422 to form sewage. The water 422 or sewage of the treated waste gas can be discharged through the drainage channel 45 and can be discharged into the sewage station for sewage treatment. At the same time, during the drying work, when the fiber sizing and drying device causes a fire due to an abnormal situation, the flames can spread along the waste gas collecting channel 41, causing waste gas leakage and polluting the environment. The water 422 in the waste gas treatment chamber 421 can also effectively block the spread of the fire, thereby effectively reducing the economic losses caused by the abnormal fire.
[0048] In some embodiments, the waste gas treatment pool 42 is provided with a liquid level meter 5, which measures the height of the liquid inside the container. The type of the liquid level meter 5 can be a magnetic flap liquid level meter, a float liquid level meter, a capacitive liquid level meter, etc., as long as it can measure the height of the liquid. In this regard, there are no excessive restrictions in the present application. The liquid level meter 5 is located on the side wall of the waste gas treatment pool 42. The staff can replenish the waste gas treatment chamber 421 with water 422 according to the liquid level height displayed by the liquid level meter 5 to ensure that the liquid level of the water 422 is higher than the height of the second end 412 of the waste gas collection channel 41.
[0049] The use steps of a fiber sizing and drying device of the present application are as follows:
[0050] like Figure 1 and Figure 2 FIG. 1 shows a fiber sizing and drying device. First, a fiber 7 impregnated with a sizing agent is placed on a roller 100 near an inlet end 12, and one end of the fiber 7 passes through a first channel of a drying section 1 through a drying chamber 11 and a second channel, and is placed again on another roller 100 near an outlet end 13, and the fiber 7 is dried along an extension direction (such as Figure 1 Drying work is carried out in the x direction as shown in FIG.
[0051] Next, the heating tube 14 of the drying section 1 is turned on, so that the heating tube 14 is heated to the required temperature, and the fiber 7 is dried. During the drying process, since the drying section 1 is inclined, the hot air generated in the drying section 1 flows from the outlet end 13 to the inlet end 12, thereby reducing the drying time. At the same time, as the temperature in the drying section 1 increases, the waste gas generated can enter the waste gas collecting channel 41 through the inlet end 12 and the outlet end 13. According to the waste gas accumulation situation, the exhaust valve 9 on the waste gas collecting channel 41 is opened or closed to control the collection and speed of the waste gas.
[0052] Afterwards, the exhaust gas is collected in the exhaust gas treatment pool 42 by the fan 6, that is, the exhaust gas is blown along the Figure 1 The waste gas enters the waste gas treatment pool 42 in the opposite direction of the x direction shown in the figure. The water 422 in the waste gas treatment pool 42 decomposes and dilutes the waste gas to reduce the concentration of the waste gas, thereby discharging the treated waste gas. In the process of drying and discharging the waste gas, the staff can measure the water volume of the water 422 according to the liquid level meter 5, and adaptively replenish and discharge the water through the water replenishment channel 44 and the drainage channel 45 set on the waste gas treatment pool 42.
[0053] Finally, the treated waste gas is discharged through the exhaust channel 43, and the treated water 422 is also discharged to the sewage station through the drainage channel 45 for further treatment, thereby completing the drying work.
