[0037] The present application will be described in detail below with reference to the embodiments shown in the drawings, but it should be noted that these embodiments are not limiting of the present application, and equivalent transformations or substitutions of function, method, or structure made by those of ordinary skill in the art based on these embodiments are within the scope of protection of the present application.
[0038] It should be noted that the drawings (for example, Figure 2 and Figure 3 , Figures 5 to 8 ) are all sectional views or partial sectional views of the heat box 100 cut along the Z-axis in the present application. Figure 2
[0039] In the process of the heat box performing heating treatment on the chemical fiber (for example, pre-drafting yarn), the chemical fiber is decomposed at high temperature or the additives added in the chemical fiber processing process volatilize in the high-temperature environment formed by the heat box, thereby forming a large amount of oil fume. In the prior art, a negative pressure source is usually connected to the smoke exhaust pipes at the upper and lower ends of the heat box, and negative pressure is formed in the heating channel inside the heat box to exhaust the oil fume from the heat box. However, since the negative pressure source is difficult to completely and timely suck out the volatilized oil fume in the heat box, with the increase of the use time, the oil mist contained in the oil fume adheres to the heat track and gradually accumulates to form oil stains. Since the heat box is usually installed obliquely in the false twist texturing machine, the heat track is inclined with the heat box, and the oil stains on the heat track naturally flow along the inclined direction of the heat track under the action of gravity, and converge to the bottom end of the heat track along the length direction of the heat track, causing the oil stains to drip from the gap between the heat track and the door plate at the bottom end of the heat track.
[0040] In particular, in order to suppress the generation of oil stains and improve the exhaust effect of the oil fume in the prior art, it is usually necessary to continuously perform the exhaust operation on the oil fume generated in the heat box or increase the suction force of the negative pressure source, but this will cause a large amount of heat loss in the heat box, thereby causing excessive heat loss of the heat box and the false twist texturing machine containing the heat box, resulting in energy waste.
[0041] The heat box 100 in the present application can be understood as a deformation heat box arranged in a false twist texturing machine, or, for example, a biphenyl heating method is used to heat process the chemical fiber N and applied to other types of fiber processing equipment (i.e. the upper concept of the false twist texturing machine), which is not specifically limited and excluded in the present application.
[0042] Referring to Figure 1 With Figure 2 As shown, the heat box 100 disclosed in the present application is used to perform heat treatment on the chemical fiber N. During the heat treatment of the chemical fiber N, the heat box 100 is closed by the guide wall 21 to reduce the heat loss in the heat box 100. At the same time, the oil dirt flows naturally along the inclined direction of the heat rail 10 and converges to the bottom end 101 of the heat rail 10. The vertical normal line of the guide wall 21 intersects with the bottom end 101 of the heat rail 10, so that when the oil dirt drops downward under the action of gravity, the guide wall 21 can receive the dropping oil dirt, and the guide wall 21 receives the oil dirt through the guide pipe 22. The oil dirt is discharged from the heat box 100 to prevent the oil dirt from dripping from the bottom end of the heat rail 10 through the gap between the heat rail 10 and the door plate 803.
[0043] The heat box 100 disclosed in the present application collects the oil dirt dripping from the bottom end of the heat rail 10 through the connecting structure 20 and discharges the oil dirt from the heat box 100, thereby effectively avoiding the pollution of the ground by the dripping high-temperature oil drops, and avoiding the personal injury to the operators in the operation channel 500 of the false twist texturing machine caused by the dripping high-temperature oil drops. The heat box 100 is provided below with a smoke exhaust pipe (i.e. a first suction pipe 70) connected to the guide pipe 22. When the first suction pipe 70 is connected to a negative pressure source, since the connecting structure 20 can collect the oil dirt at the bottom end 101 of the heat rail 10 and discharge the oil dirt from the heat box 100, the demand for the exhaust volume of the negative pressure source can be reduced, and high-intensity oil smoke exhaust operation is not required. Even when the first suction pipe 70 is not connected to the negative pressure source, the oil dirt at the bottom end 101 of the heat rail 10 can be guided into the first suction pipe 70 through the connecting structure 20 under the action of gravity and discharged from the heat box 100, so as to prevent the oil dirt from accumulating in the heat box 100. Thus, the heat loss in the heat box 100 caused by the oil smoke exhaust operation can be further reduced, the energy waste is reduced, and the energy saving and consumption reduction of the heat box 100 and the false twist texturing machine 1000 containing the heat box 100 are achieved. The energy consumption to be reduced in the present application can be considered as the energy consumption produced by the heat box 100 containing the heat rail 10, or as the energy consumption produced by the whole false twist texturing machine 1000 containing the heat box 100, or as the energy consumption produced by the false twist texturing machine 1000 and the negative pressure source together, or as the energy consumption produced by the negative pressure source.
[0044] Referring to Figures 1 to 4As shown, the heat box 100 comprises a box body 80, a plurality of heat tracks 10 arranged in the box body 80, a heating channel 801 formed in the box body 80 along the length direction of the box body 80 and arranged with the heat tracks 10, and a guide structure 20 arranged below the heat tracks 10 in the heating channel 801 along the vertical direction (indicated by the Z-axis). Figure 2 The heating channel 801 forms an outlet portion 802 for the chemical fibers to be discharged in the box body 80. The guide structure 20 comprises a flow guide wall 21 intersecting the vertical normal line of the bottom end 101 of the heat track 10, a window 211 formed in the flow guide wall 21 for the chemical fibers N to pass through, and a flow guide pipe 22 connected to the flow guide wall 21 to discharge the oil stains and / or oil fume out of the box body 80, and the flow guide wall 21 partially encloses the outlet portion 802. During the heating process of the chemical fibers N in the heat box 100, the outlet portion 802 is partially enclosed by the flow guide wall 21, which can reduce the escape of hot air in the heat box 100 and block the cold air from entering the heat box 100, thereby reducing the heat loss in the heat box 100. At the same time, the oil stains on the heat track 10 naturally flow along the inclined direction of the heat track 10 under the action of gravity and converge to the bottom end 101 of the heat track 10. The oil stains converged to the bottom end 101 of the heat track 10 will drip downward under the action of gravity. The vertical normal line of the bottom end 101 of the heat track 10 intersects the flow guide wall 21, so that the dripping oil stains can be received by the flow guide wall 21, and the oil stains received by the flow guide wall 21 can be discharged out of the heat box 100 through the flow guide pipe 22, to prevent the oil stains from dripping from the gap between the heat track 10 and the door panel 803 at the bottom end of the heat track 10.
[0045] In some examples, the heat box 100 is arranged in the heat box 100. Figure 2 As shown, the box body 80 is the outer shell of the heat box 100, used to accommodate the heat tracks 10 and the guide structure 20. The chemical fibers N form a moving path M when being transported into the heat box 100, and the chemical fibers N are heated by the high-temperature environment in the heat box 100 and discharged out of the heat box 100 through the outlet portion 802. The flow guide wall 21 is provided with the window 211 for the chemical fibers N to be discharged in the heat box 100, to avoid the interference of the guide structure 20 with the moving path M of the chemical fibers N. Since the heat box 100 is installed obliquely in the false twist texturing machine 1000, the heat tracks 10 are inclined with the heat box 100, so that the heat tracks 10 have a certain inclination angle with respect to the horizontal plane H, for example, 50°, 55°, 60°, etc., so that the oil stains can naturally flow along the inclined direction of the heat tracks 10 under the action of gravity to converge to the bottom end 101 of the heat tracks 10 along the length direction of the heat tracks 10.
[0046] In some examples, the heat box 100 is arranged in the heat box 100. Figure 3As shown, when the heat box 100 is provided with the first suction pipe 70 in communication with the flow guide pipe 22, and the first suction pipe 70 is connected to the negative pressure source, the negative pressure source forms a suction force on the heating channel 801 through the first suction pipe 70 and the flow guide pipe 22, so as to discharge the oil fume and / or the oil stain collected by the ignition structure 20 from the heat box 100 through the flow guide pipe 22, thereby improving the working efficiency of discharging the oil fume and / or the oil stain, and reducing the suction power consumption of the negative pressure source.
[0047] In some examples, the heat box 100 is provided with a first suction pipe 70 in communication with the flow guide pipe 22, and the first suction pipe 70 is connected to the negative pressure source. Figure 3 As shown, the heat rail 10 is provided with a plurality of grooves 12 for heating the chemical fiber N along the length direction of the heat rail 10, and a groove wall 13 formed on both sides of the groove 12; the vertical normal line V2 of the bottom end 121 of the groove 12 along the length direction of the heat rail 10 intersects with the flow guide wall 21, and the vertical normal line V1 of the bottom end 131 of the groove wall 13 along the length direction of the heat rail 10 intersects with the flow guide wall 21. The vertical normal line of the bottom end 101 of the heat rail 10 includes the vertical normal line V1 of the bottom end 131 of the groove wall 13 and the vertical normal line V2 of the bottom end 121 of the groove 12. In the process of heating the chemical fiber N by the heat box 100, the oil mist contained in the oil fume adheres to the surface of the groove wall 13 and the groove 12 and gradually forms oil stains, and the oil stains on the surface of the groove wall 13 and the groove 12 naturally flow along the inclined direction of the heat rail 10 under the action of gravity to converge at the bottom end 131 of the groove wall 13 and the bottom end 121 of the groove 12, so that the oil stains at the bottom end 131 of the groove wall 13 and the bottom end 121 of the groove 12 drop downward along the vertical normal line V1 and the vertical normal line V2, respectively, and are received by the flow guide wall 21. Figure 3 As shown, the oil stains at the bottom end 131 of the groove wall 13 drop downward along the vertical normal line V1 to the flow guide wall 21, and the oil stains at the bottom end 121 of the groove 12 drop downward along the vertical normal line V2 to the flow guide wall 21, so as to realize that the flow guide wall 21 receives the oil stains dropped downward from the bottom end 101 of the heat rail 10, and discharges the oil stains received by the flow guide wall 21 from the heat box 100 through the flow guide pipe 22, thereby preventing the oil stains from dropping from the gap between the heat rail 10 and the door panel 803. Figure 3 As shown, the oil stains at the bottom end 131 of the groove wall 13 drop downward along the vertical normal line V1 to the flow guide wall 21, and the oil stains at the bottom end 121 of the groove 12 drop downward along the vertical normal line V2 to the flow guide wall 21, so as to realize that the flow guide wall 21 receives the oil stains dropped downward from the bottom end 101 of the heat rail 10, and discharges the oil stains received by the flow guide wall 21 from the heat box 100 through the flow guide pipe 22, thereby preventing the oil stains from dropping from the gap between the heat rail 10 and the door panel 803.
[0048] In some examples, the heat box 100 is provided with a first suction pipe 70 in communication with the flow guide pipe 22, and the first suction pipe 70 is connected to the negative pressure source. Figures 2 to 5 As shown, the flow guide wall 21 includes a flow guide portion 212 inclined relative to the horizontal plane H and forming an acute angle a1 with the horizontal plane H, and the flow guide pipe 22 is connected to the flow guide portion 212 to receive the oil stains dropped from the bottom end 101 of the heat rail 10 to the flow guide portion 212. The oil stains converged at the bottom end 101 of the heat rail 10 drop downward under the action of gravity, and the flow guide portion 212 intersects with the vertical normal line of the bottom end 101 of the heat rail 10, so that the dropped oil stains can be received by the flow guide portion 212, and the flow guide portion 212 is inclined relative to the horizontal plane H and forms an acute angle a1 with the horizontal plane H, so that the flow guide portion 212 can guide the oil stains to drop along the vertical normal line of the bottom end 101 of the heat rail 10 under the action of gravity. Figure 3 As shown, the flow guide wall 21 includes a flow guide portion 212 inclined relative to the horizontal plane H and forming an acute angle a1 with the horizontal plane H, and the flow guide pipe 22 is connected to the flow guide portion 212 to receive the oil stains dropped from the bottom end 101 of the heat rail 10 to the flow guide portion 212. The oil stains converged at the bottom end 101 of the heat rail 10 drop downward under the action of gravity, and the flow guide portion 212 intersects with the vertical normal line of the bottom end 101 of the heat rail 10, so that the dropped oil stains can be received by the flow guide portion 212, and the flow guide portion 212 is inclined relative to the horizontal plane H and forms an acute angle a1 with the horizontal plane H, so that the flow guide portion 212 can guide the oil stains to drop along the vertical normal line of the bottom end 101 of the heat rail 10 under the action of gravity. Figure 5The oil flows in the direction indicated by the middle arrow B3 to enter the guide pipe 22, and the oil received by the guide section 212 is discharged from the heat box 100 through the guide pipe 22 to prevent the oil from dripping from the bottom of the heat rail 10 through the gap between the heat rail 10 and the door panel 803. In some examples, a window 211 is opened in the guide section 212 to allow the chemical fiber N to be discharged into the heat box 100, so as to avoid the guide wall 21 interfering with the movement path M of the chemical fiber N.
[0049] In some examples, the parameter Figure 3 and Figure 5 As shown, by adjusting the acute angle α1, the flow direction and velocity of the oil on the guide section 212 are adjusted. The larger the acute angle α1, the stronger the component of gravity that causes the oil to flow along the guide section 212, thus making the oil flow faster on the guide section 212, thereby improving the discharge efficiency and preventing the oil from stagnating and accumulating in the guide section 212. Preferably, the acute angle α1 is greater than or equal to 30° and less than or equal to 60°.
[0050] In some examples, the parameter Figure 4 As shown, the width w2 of the flow guide 212 formed laterally is greater than or equal to the width w3 of the bottom end 101 of the hot rail 10 formed laterally. This is to ensure that the flow guide 212 can fully receive the oil stains at the bottom end 101 of the hot rail 10, and to prevent the oil stains from leaking into or outside the housing 80.
[0051] In some examples, the parameter Figure 3 and Figure 4 As shown, the diameter w1 of the pipe opening formed laterally at one end of the guide pipe 22 connected to the guide section 212 is greater than or equal to the width w2 formed laterally on the guide section 212. This is to allow the oil slick to move along the guide section 212. Figure 4 When the flow is in the direction indicated by the middle arrow B3, it can be completely guided into the guide pipe 22 to prevent oil from overflowing or deviating from the guide pipe 22, ensuring that the oil can be completely discharged and avoiding oil leakage into the inside or outside of the box 80.
[0052] In some examples, the parameter Figure 6 As shown, the guide wall 21 also includes: two opposing sidewalls 213 extending along the length of the guide section 212, and a baffle 214 disposed in the guide section 212 and laterally connected to the sidewalls 213; the guide section 212, the sidewalls 213, and the baffle 214 together form a collection trough 210 communicating with the guide pipe 22 to receive oil dripping from the bottom end 101 of the hot rail 10 to the guide section 212. The oil that converges to the bottom end 101 of the hot rail 10 drips downward under the action of gravity. The guide section 212 intersects with the vertical normal of the bottom end 101 of the hot rail 10, so that the dripping oil can be received by the guide section 212. Because the guide section 212 is inclined relative to the horizontal plane H and forms an acute angle α1 with the horizontal plane H, the guide section 212 can guide the oil along the direction of gravity.Figure 6 The oil stains in the collecting groove 210 are discharged from the heat box 100 through the guide pipe 22 to prevent the oil stains from dripping from the bottom end of the heat rail 10 through the gap between the heat rail 10 and the door panel 803. The oil stains dripping onto the guide portion 212 can be intercepted and guided through the side wall 213 to prevent the oil stains from escaping from the collecting groove 210 and leaking into or outside the box body 80.
[0053] In some examples, the width of the collecting groove 210 formed in the transverse direction is greater than or equal to the width of the bottom end 101 of the heat rail 10 formed in the transverse direction. In this way, the collecting groove 210 can receive the oil stains dripping downward from the bottom end 101 of the heat rail 10 to prevent the oil stains from leaking into or outside the box body 80.
[0054] In some examples, the width of the collecting groove 210 formed in the transverse direction is greater than or equal to the width of the bottom end 101 of the heat rail 10 formed in the transverse direction. In this way, the collecting groove 210 can receive the oil stains dripping downward from the bottom end 101 of the heat rail 10 to prevent the oil stains from leaking into or outside the box body 80. Figure 3 As shown, the heat box 100 further comprises a support plate 81 arranged in the box body 80 and connected to the guide wall 21. The connecting structure 20 further comprises a support wall 215 arranged on the guide wall 21, and the support wall 215 is provided with a plurality of positioning holes 2151. The guide wall 21 is connected and fixed to the support plate 81 by passing through the positioning holes 2151 with fixing members such as bolts (not shown) to ensure the position stability of the connecting structure 20 and prevent the connecting structure 20 from moving due to vibration or other factors. In some examples, the connecting structure 20 can also be installed in the box body 80 and arranged below the heat rail 10 by welding, insertion or other methods, which are not limited in the present application.
[0055] In some examples, the width of the collecting groove 210 formed in the transverse direction is greater than or equal to the width of the bottom end 101 of the heat rail 10 formed in the transverse direction. In this way, the collecting groove 210 can receive the oil stains dripping downward from the bottom end 101 of the heat rail 10 to prevent the oil stains from leaking into or outside the box body 80. Figure 7 With Figure 8 As shown, the bottom end 101 of the heat rail 10 is at least partially provided with a guide portion 11 inclined relative to the horizontal plane H, and the guide portion 11 forms an acute angle a2 with the horizontal plane H. The guide portion 11 extends through the bottom end of the groove 12 and the groove wall 13, and the guide portion 11 forms a discharge guide portion 111 extending through the bottom end 121 of the groove 12. The vertical normal V3 of the bottom end 112 of the discharge guide portion 111 in the inclined direction intersects with the guide portion 212. During the heating process of the chemical fiber N by the heat box 100, the oil mist contained in the oil fume adheres to the surfaces of the groove wall 13 and the groove 12 and gradually forms oil stains. The oil stains on the surfaces of the groove wall 13 and the groove 12 respectively flow along the guide portion 212 and the guide portion 11 under the action of gravity. Figure 8 The oil stains flow in the directions indicated by the arrows B01 and B02 to converge on the guide portion 11 and flow along the guide portion 11 in the direction indicated by the arrow B03. Figure 7 Or Figure 8 The oil stains flow along the guide portion 11 in the direction indicated by the arrow B1, and the vertical normal V3 of the bottom end 112 of the discharge guide portion 111 intersects with the guide portion 212, so that the oil stains will flow along the guide portion 212 in the direction indicated by the arrow B2 at the bottom end 112 of the discharge guide portion 111. Figure 7The oil dirt drops downward in the direction indicated by the middle arrow B2 to the flow guide part 212, so as to realize that the flow guide wall 21 receives the oil dirt dropping downward from the bottom end 101 of the heat track 10, and the flow guide wall 21 receives the oil dirt is discharged from the heat box 100 through the flow guide pipe 22, preventing the oil dirt from dropping from the bottom end of the heat track 10 through the gap between the heat track 10 and the door panel 803.
[0056] In some examples, the guide part 11 is configured to be at least one of a plane and a curved surface. Figure 8 As shown, the guide part 11 extends downwardly relative to the horizontal plane H, and the guide part 11 forms an acute angle a2 with the horizontal plane H. The angle of the acute angle a2 is adjusted to adjust the flow direction and flow rate of the oil dirt. The greater the angle of the acute angle a2, the stronger the gravity component of the oil dirt along the guide part 11, so that the flow speed of the oil dirt on the guide part 11 is faster, so as to improve the discharge efficiency, while avoiding the oil dirt stagnating and accumulating on the guide part 11. Preferably, the acute angle a2 is greater than or equal to 15° and less than or equal to 75°.
[0057] In some examples, the guide part 11 is configured to be at least one of a plane and a curved surface. Figure 8 As shown, the cross-sectional shape of the guide part 11 cut along the Z axis is a plane that is downwardly inclined relative to the horizontal plane, or the cross-sectional shape of the guide part 11 cut along the Z axis is a curved surface that is downwardly curved relative to the horizontal plane (this state is not shown), or even a combination of a curved surface and a plane (this state is not shown). The guide part 11 can also be other shapes that can guide the oil dirt to drop to the flow guide wall 21, which are not limited in the present application.
[0058] In some examples, the guide part 11 is configured to be at least one of a plane and a curved surface. Figure 2 With Figure 3As shown, the heat box 100 further comprises a first suction pipe 70 connected with the communication flow guide pipe 22. According to different working requirements, the first suction pipe 70 can be connected with or not connected with a negative pressure source (not shown). When the first suction pipe 70 is connected with the negative pressure source (for example, a vacuum pump), the negative pressure source generates an exhaust negative pressure, and through the first suction pipe 70 and the flow guide pipe 22, the oil fume in the heat box 100 is sucked, and the oil stains collected by the connecting structure 20 can be exhausted. Under the action of the suction force, the oil stains can be quickly exhausted from the flow guide pipe 22 and the first suction pipe 70 to the heat box 100, improving the exhaust efficiency of the oil stains, so as to realize the exhaust of the oil stains and the oil fume from the heat box 100. Since the connecting structure 20 can collect the oil stains at the bottom end 101 of the heat rail 10 and exhaust the oil stains from the heat box 100, the exhaust air volume of the negative pressure source can be reduced, and the high-intensity oil fume exhaust operation does not need to be continuously performed. Even when the first suction pipe 70 is not connected with the negative pressure source, the oil stains at the bottom end 101 of the heat rail 10 can flow into the first suction pipe 70 through the connecting structure 20 under the action of gravity, so as to be exhausted from the heat box 100. Thus, the heat loss in the heat box 100 caused by the oil fume exhaust operation is reduced, and the energy waste is reduced, so as to achieve the energy saving and consumption reduction of the heat box 100 and the false twist texturing machine 1000 comprising the heat box 100.
[0059] In some examples, the first suction pipe 70 is integrally formed with the flow guide pipe 22. Thus, the connection stability between the flow guide pipe 22 and the first suction pipe 70 is high, and no additional fixing structure is needed. Moreover, the gap formed between the first suction pipe 70 and the flow guide pipe 22 can be reduced, so as to reduce the risk of oil stain and / or oil fume leakage.
[0060] In some examples, the first suction pipe 70 is formed separately from the flow guide pipe 22. Thus, the independence between the first suction pipe 70 and the flow guide pipe 22 is maintained, and the configuration and position of the first suction pipe 70 and the flow guide pipe 22 can be adjusted according to actual requirements. For example, the length, angle or position of the first suction pipe 70 and the flow guide pipe 22 can be adjusted according to the space layout. Moreover, the first suction pipe 70 and the flow guide pipe 22 can be independently installed, disassembled, inspected and cleaned.
[0061] In some examples, the first suction pipe 70 is integrally formed with the flow guide pipe 22. Thus, the connection stability between the flow guide pipe 22 and the first suction pipe 70 is high, and no additional fixing structure is needed. Moreover, the gap formed between the first suction pipe 70 and the flow guide pipe 22 can be reduced, so as to reduce the risk of oil stain and / or oil fume leakage. Figure 2 With Figure 3As shown, the heat box 100 further comprises a second suction pipe 90 connected to the box body 80 and arranged away from the lead-in structure 20. The first suction pipe 70 and the second suction pipe 90 form the same or different suction forces. The first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source; or, the first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources, at this time, the negative pressure sources connected to the first suction pipe 70 and the second suction pipe 90 respectively form the same or different exhaust negative pressure and suction air volume. When the first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source, the negative pressure source only needs to provide a constant and uniform pressure, so that the suction forces of the first suction pipe 70 and the second suction pipe 90 are the same. And the negative pressure source can maintain a stable negative pressure state by providing a constant and uniform pressure, so that the power consumption of the negative pressure source can remain stable, which helps to reduce energy consumption, avoids the increase of energy consumption caused by power fluctuation, and realizes higher energy use efficiency.
[0062] In some examples, when the first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources, the different negative pressure sources can also provide a constant and uniform pressure to the first suction pipe 70 and the second suction pipe 90, so that the suction forces of the first suction pipe 70 and the second suction pipe 90 are the same. In addition, the first suction pipe 70 and the second suction pipe 90 can adjust different suction forces according to the respective negative pressure sources. The power consumption of the negative pressure source will depend on the exhaust negative pressure and suction air volume independently provided and formed. Each negative pressure source needs to provide different exhaust negative pressure and suction air volume according to the needs of the suction pipe (i.e., the first suction pipe 70 and the second suction pipe 90) connected thereto.
[0063] In some examples, referring to Figure 2 With Figure 3As shown, the suction force formed by the second suction pipe 90 is greater than the suction force formed by the first suction pipe 70. The first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources, and the suction force of the first suction pipe 70 and the second suction pipe 90 on the heating channel 801 is flexibly controlled by adjusting the pressure of the negative pressure source, so that the suction force formed by the second suction pipe 90 on the heating channel 801 is greater than the suction force formed by the first suction pipe 70 on the heating channel 801. The suction pipe port (not shown) of the second suction pipe 90 extends into the top of the heating channel 801, and the high-temperature oil fume rises to the top of the heating channel 801, so that the second suction pipe 90 with stronger suction force can more effectively exhaust the oil fume in the heat box 100. The first suction pipe 70 with smaller suction force can make the oil fume flowing to the connecting structure 20 naturally by gravity without forced suction, and the oil fume flows into the first suction pipe 70 through the flow guide pipe 22 and is exhausted, thereby reducing the heat loss in the heat box 100 caused by the oil fume exhaust operation. By providing lower suction force by the first suction pipe 70 relative to the second suction pipe 90 or not connecting the negative pressure source to the first suction pipe 70, the second suction pipe 90 provides stronger suction force, so that the power output of the two negative pressure sources connected to the first suction pipe 70 and the second suction pipe 90 respectively matches the required suction force, avoiding excessive suction of hot air in the heating channel 801, thereby reducing the heat loss of the heat box 100 and the false twist texturing machine 1000 containing the heat box 100, and reducing the energy consumption of the heat box 100 and the false twist texturing machine 1000.
[0064] Based on the same inventive concept, the embodiment also discloses a false twist texturing machine 1000, which is described in detail as follows. Figure 9 As shown, the false twist texturing machine 1000 comprises a yarn conveying device 200, a cooling device 300, a false twist device 400, and a heat box 100 arranged between the yarn conveying device 200 and the cooling device 300. The heat box 100, the cooling device 300 and the false twist device 400 are arranged in sequence after the yarn conveying device 200. Since the yarn conveying device 200, the cooling device 400 and the false twist device 300 are prior art, they will not be described here. The false twist texturing machine 1000 with the heat box 100 can reduce heat loss and energy waste in actual application, which is helpful to realize energy saving and consumption reduction.
