Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a flow guiding device and a hot rail device. Background Technology

[0002] During the processing of chemical fiber filaments, for example, when a hot box heats pre-drawn yarn (POY) and other chemical fibers, and then stretches the chemical fibers by subsequent conveying rollers, and when a false twisting device is used to perform false twisting deformation on the heated chemical fibers, a large amount of oil fumes are generated because the chemical fibers decompose at high temperatures or the additives added during the chemical fiber processing volatilize in the high-temperature environment formed by the hot box.

[0003] Existing technologies typically employ a negative pressure source connected to the exhaust pipe of the heating box, creating negative pressure inside the box to expel cooking fumes. However, because the negative pressure source cannot completely and promptly extract the volatile cooking fumes from the heating box, over time, the oil mist contained in the fumes adheres to the heating rails and gradually accumulates, forming grease. Since the heating box is usually installed at an angle, the grease on the heating rails drips from the gap between the heating rails and the door panel under gravity. In particular, to suppress grease formation and improve the extraction efficiency of cooking fumes, existing technologies usually require continuous extraction of cooking fumes from the heating box or increased suction force of the negative pressure source. However, this results in significant heat loss from the heating box, leading to excessive heat loss from the heating box and the false-twisting texturing machine containing it, resulting in energy waste.

DETAILED DESCRIPTION

[0043] ​The utility model will be explained in detail in combination with the embodiments shown in the drawings, but it should be explained that these embodiments are not the limitation of the utility model, the equivalent transformation or substitution of function, method or structure made by the ordinary skilled in the art according to these embodiments all belong to the protection scope of the utility model.

[0044] It should be noted that the drawings (for example, Figures 3 to 6 , Figure 8 , Figures 13 to 16 ) contained in the specification of the present application are all sectional views or partial sectional views formed by cutting the hot box 100 along the Z-axis in Figure 3 .

[0045] In the process of the hot 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 hot 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 hot box, and negative pressure is formed in the hot box (i.e., the space region formed between the hot rail 10 and the door plate 801) to exhaust the oil fume from the hot box. However, since the negative pressure source is difficult to completely and timely suck out the volatilized oil fume in the hot box, with the increase of the use time, the oil mist contained in the oil fume adheres to the hot rail and gradually accumulates to form oil stains. Since the hot box is usually installed obliquely in the false twist texturing machine, the hot rail is inclined with the hot box, and the oil stains on the hot rail naturally flow along the inclined direction of the hot rail under the action of gravity, converge to the bottom end of the hot rail along the length direction of the hot rail, and cause the oil stains to drip from the bottom end of the hot rail through the gap between the hot rail and the door plate.

[0046] Especially, in order to suppress the generation of oil stains and improve the exhaust effect of the oil fume, it is usually necessary to continuously perform the exhaust operation on the oil fume generated in the hot box or increase the suction force of the negative pressure source, but this will cause a large amount of heat loss in the hot box, thereby causing excessive heat loss of the hot box and the false twist texturing machine containing the hot box, and causing energy waste.

[0047] The hot box 100 in the present application can be understood as a texturing hot box configured in a false twist texturing machine (not shown), or, for example, a diphenyl heating method is used to heat treat the chemical fiber N and applied to other types of fiber processing equipment (i.e., the upper concept of the false twist texturing machine), and the present application is not specifically limited and excluded.

[0048] In some examples, the hot box 100 is configured in a false twist texturing machine (not shown). Figure 3As shown, the box 80 is the shell of the heat box 100, for accommodating the heat rail 10 and the flow guide device 20. The chemical fiber N is conveyed into the heat box 100 to form a moving path M, and the chemical fiber N is heated by the high-temperature environment in the heat box 100. Since the heat box 100 is installed obliquely on the false twist texturing machine, the heat rail 10 is inclined with the heat box 100, so that the heat rail 10 has a certain inclination angle, for example, 50°, 55°, 60°, etc., relative to the horizontal plane, so that the oil stains can flow naturally along the inclined direction of the heat rail 10 under the action of gravity to converge to the bottom end 101 of the heat rail 10 along the length direction.

[0049] Referring to Figure 3 With Figure 4 As shown, the flow guide device 20 disclosed in the present application is arranged at the bottom end 101 of the heat rail 10 along the length direction included in the heat box 100. The bottom end 101 of the heat rail 10 is configured with an inclined guide part 11 extending towards the flow guide device 20, and the oil stains flowing naturally along the inclined direction of the heat rail 10 converge to the inclined guide part 11. The oil stains flow along the inclined direction of the inclined guide part 11 (for example, the direction shown by the arrow B1 in FIG. 1), and the flow guide wall 21 abuts against the bottom end 101 of the heat rail 10 (i.e., the inclined guide part 11) or partially extends into the bottom end 101 of the heat rail 10, so that the oil stains converged to the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the flow guide wall 21, and the oil stains are guided into the flow guide groove 210 through the flow guide wall 21, and the flow guide groove 210 is inclined downward relative to the horizontal plane, so as to guide the oil stains to flow along the direction shown by the arrow B2 in FIG. 1 on the flow guide wall 21, thereby guiding the oil stains to flow along the flow guide pipe 22 along the direction shown by the arrow B3 in FIG. 1, so as to discharge the oil stains in the heat box 100 through the discharge channel 23, and prevent the oil stains from dripping from the bottom end 101 of the heat rail 10 between the heat rail 10 and the door plate 801. The flow guide device 20 disclosed in the present application collects the oil stains converged at the bottom end 101 of the heat rail 10 and discharges the oil stains out of the heat box 100, thereby effectively avoiding the pollution of the ground by the dripping high-temperature oil drops, and avoiding the personal injury of the operators in the operation channel of the false twist texturing machine caused by the dripping high-temperature oil drops. Figure 4 Figure 4 In some examples, referring to Figure 4

[0050] In some examples, referring to Figure 4 ​​As shown, the heat box 100 is provided below with an exhaust pipe 70 connected with the guide pipe 22 of the guide device 20, and the exhaust pipe 70 is in communication with the exhaust channel 23. The exhaust pipe 70 can be externally connected with a negative pressure source, and the negative pressure source forms a suction force through the exhaust pipe 70 and the exhaust channel 23 to the inside of the heat box 100, so as to discharge the oil fume and / or the oil stain collected by the guide device 20 from the heat box 100 through the guide device 20, thereby improving the working efficiency of discharging the oil fume and / or the oil stain and reducing the suction power consumption. The guide device 20 disclosed in the present application collects the oil stain gathered at the bottom end 101 of the heat rail 10 and discharges the oil stain from the heat box 100, so as to reduce the need for the heat box 100 to continuously perform high-intensity oil fume suction and discharge operation, reduce the demand of the heat box 100 on the exhaust volume of the negative pressure source, and even eliminate the need for the exhaust pipe 70 connected with the guide device 20 below the heat box 100 to be connected with the negative pressure source, thereby reducing the heat loss in the heat box 100 and the false twist texturing machine (not shown) containing the heat box 100, reducing energy waste, and achieving the purpose of energy saving and consumption reduction. The energy consumption to be reduced in the present application can be considered as the energy consumption of the heat box 100 containing the heat rail 10, or the energy consumption of the false twist texturing machine containing the heat box 100 as a whole, or the energy consumption of the false twist texturing machine and the negative pressure source together, or the energy consumption of the negative pressure source.

[0051] Referring to Figures 1 to 7 As shown, the guide device 20 includes a guide wall 21 abutting against the bottom end 101 of the heat rail 10 or partially extending into the bottom end 101 of the heat rail 10, the guide wall 21 forms a guide groove 210 inclined downward as a whole relative to the horizontal plane, and a guide pipe 22 in communication with the guide groove 210, and the guide groove 210 and the guide pipe 22 together form an exhaust channel 23 for discharging the oil fume and / or the oil stain from the heat box 100. During the heating process of the chemical fiber N performed by the heat box 100, the oil stain on the heat rail 10 naturally flows along the inclined direction of the heat rail 10 under the action of gravity, converges to the bottom end of the heat rail 10 along the length direction of the heat rail 10, and flows along the inclined guide part 11 to the guide wall 21 in the direction indicated by arrow B1 in the middle of FIG. 2, and the oil stain on the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the guide wall 21 to enter the guide groove 210 and flow to the guide pipe 22 in the direction indicated by arrow B2 in the middle of FIG. 2 through the guide of the guide wall 21, and then the oil stain is discharged from the inside of the heat box 100 through the exhaust channel 23. Figure 4 As shown, the guide device 20 includes a guide wall 21 abutting against the bottom end 101 of the heat rail 10 or partially extending into the bottom end 101 of the heat rail 10, the guide wall 21 forms a guide groove 210 inclined downward as a whole relative to the horizontal plane, and a guide pipe 22 in communication with the guide groove 210, and the guide groove 210 and the guide pipe 22 together form an exhaust channel 23 for discharging the oil fume and / or the oil stain from the heat box 100. During the heating process of the chemical fiber N performed by the heat box 100, the oil stain on the heat rail 10 naturally flows along the inclined direction of the heat rail 10 under the action of gravity, converges to the bottom end of the heat rail 10 along the length direction of the heat rail 10, and flows along the inclined guide part 11 to the guide wall 21 in the direction indicated by arrow B1 in the middle of FIG. 2, and the oil stain on the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the guide wall 21 to enter the guide groove 210 and flow to the guide pipe 22 in the direction indicated by arrow B2 in the middle of FIG. 2 through the guide of the guide wall 21, and then the oil stain is discharged from the inside of the heat box 100 through the exhaust channel 23. Figure 4 As shown, the guide device 20 includes a guide wall 21 abutting against the bottom end 101 of the heat rail 10 or partially extending into the bottom end 101 of the heat rail 10, the guide wall 21 forms a guide groove 210 inclined downward as a whole relative to the horizontal plane, and a guide pipe 22 in communication with the guide groove 210, and the guide groove 210 and the guide pipe 22 together form an exhaust channel 23 for discharging the oil fume and / or the oil stain from the heat box 100. During the heating process of the chemical fiber N performed by the heat box 100, the oil stain on the heat rail 10 naturally flows along the inclined direction of the heat rail 10 under the action of gravity, converges to the bottom end of the heat rail 10 along the length direction of the heat rail 10, and flows along the inclined guide part 11 to the guide wall 21 in the direction indicated by arrow B1 in the middle of FIG. 2, and the oil stain on the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the guide wall 21 to enter the guide groove 210 and flow to the guide pipe 22 in the direction indicated by arrow B2 in the middle of FIG. 2 through the guide of the guide wall 21, and then the oil stain is discharged from the inside of the heat box 100 through the exhaust channel 23.

[0052] In some examples, referring to Figures 4 to 6As shown, the discharge passage 23 is jointly formed by the flow guide groove 210 and the flow guide pipe 22 to provide a continuous and unobstructed flow path for the oil stains. By inclining the flow guide groove 210 as a whole downward relative to the horizontal plane, the oil stains are provided with a natural flow force to the lowest point, and under the action of gravity, the oil stains flow along the inclined surface of the flow guide wall 21 to the flow guide pipe 22 and are discharged from the heat box 100 through the flow guide pipe 22, avoiding the accumulation or leakage of the oil stains in the heat box 100, so as to achieve smooth discharge of the oil stains. The discharge passage 23 can also be used to discharge the oil fume from the heat box 100. When the heat box 100 is provided with a smoke exhaust pipe 70 communicating with the discharge passage 23, and the smoke exhaust pipe 70 is connected to a negative pressure source, the negative pressure source forms a suction force on the inside of the heat box 100 through the smoke exhaust pipe 70 and the discharge passage 23, so as to discharge the oil fume in the heat box 100 and / or the oil stains collected by the flow guide device 20 from the heat box 100 through the discharge passage 23. Therefore, the working efficiency of discharging the oil stains and / or the oil fume can be improved, and the suction power consumption can be reduced.

[0053] In some examples, the flow guide wall 21 is inclined relative to the horizontal plane H. Figure 4 As shown, the flow guide groove 210 is inclined as a whole downward relative to the horizontal plane H, and the extension direction E of the flow guide groove 210 forms an acute angle a2 with the horizontal plane H. By adjusting the angle of the acute angle a2, the flow direction and flow rate of the oil stains can be adjusted. In the case where the flow guide wall 21 does not interfere with the movement path M of the chemical fiber N, the greater the angle of the acute angle a2, the stronger the component force of the oil stains flowing along the flow guide wall 21 under the action of gravity, so that the flow speed of the oil stains on the flow guide wall 21 is faster, thereby improving the discharge efficiency while avoiding the stagnation and accumulation of the oil stains on the flow guide wall 21. Preferably, the acute angle a2 is greater than or equal to 30° and less than or equal to 60°.

[0054] In some examples, the flow guide wall 21 is arranged to abut against the bottom end 101 of the heat rail 10 or partially extend into the bottom end 101 of the heat rail 10, so as to guide the oil stains to flow along the inclined guide portion 11 to the flow guide wall 21. Figure 4 As shown, the flow guide wall 21 abuts against the bottom end 101 of the heat rail 10, directly contacts and tightly abuts against the bottom end 101 of the heat rail 10, and is tightly connected with the bottom end 101 of the heat rail 10, so that the oil stains on the bottom end 101 of the heat rail 10 can smoothly flow along the inclined guide portion 11 to the flow guide wall 21 and then flow along the flow guide wall 21 to the flow guide pipe 22, so as to be discharged from the heat box 100 through the discharge passage 23. In some examples, the flow guide wall 21 partially extends into the bottom end 101 of the heat rail 10 (not shown), so that the joint between the flow guide wall 21 and the bottom end 101 of the heat rail 10 is more tightly connected, thereby reducing the gap that may exist and preventing the oil stains from leaking during the flow along the inclined guide portion 11 to the flow guide wall 21, thereby reducing the risk of pollution of the working area outside the heat box 100.

[0055] In some examples, the flow guide wall 21 is arranged to abut against the bottom end 101 of the heat rail 10 or partially extend into the bottom end 101 of the heat rail 10, so as to guide the oil stains to flow along the inclined guide portion 11 to the flow guide wall 21. Figure 1 In some examples, the flow guide wall 21 is arranged to abut against the bottom end 101 of the heat rail 10 or partially extend into the bottom end 101 of the heat rail 10, so as to guide the oil stains to flow along the inclined guide portion 11 to the flow guide wall 21. Figure 4As shown, the flow guide wall 21 comprises a bottom wall 211 abutting against or partially extending into the bottom end 101 of the heat track 10, and two oppositely arranged side walls 212 extending along the length direction of the bottom wall 211; the bottom wall 211 and the side walls 212 jointly form a flow guide groove 210 of the flow guide pipe 22 to at least discharge the oil dirt and / or oil fume out of the heat box 100. By contacting or partially extending into the bottom end 101 of the heat track 10 through the bottom wall 211, it is ensured that the oil dirt can flow along the bottom end 101 of the heat track 10 to the bottom wall 211, and then flow along the bottom wall 211 to the flow guide pipe 22, and then flow out of the heat box 100 through the discharge passage 23, so as to prevent the oil dirt from accumulating in the heat box 100. Figure 4 As shown, the oil dirt flows along the inclined guide part 11 to the bottom wall 211 in the direction of the arrow B1, so as to be guided by the bottom wall 211 to enter the flow guide groove 210, and then be guided by the bottom wall 211 to the flow guide pipe 22, and then be discharged out of the heat box 100 through the discharge passage 23, so as to prevent the oil dirt from accumulating in the heat box 100. Moreover, the two oppositely arranged side walls 212 form the boundary of the flow guide groove 210, so as to keep the flow path of the oil dirt in the flow guide groove 210, and ensure that the oil dirt flows along the bottom wall 211 to the flow guide pipe 22, and avoid deviating from the flow path to cause leakage.

[0056] In some examples, as shown in FIG. 2, the flow guide pipe 22 comprises a pipe body 221 and a pipe head 222 connected to the pipe body 221. Figure 12 As shown, the pipe opening diameter w1 of the end of the flow guide pipe 22 connected to the bottom wall 211 is greater than or equal to the width w2 of the flow guide groove 210 formed in the transverse direction. So that when the oil dirt flows along the bottom wall 211 in the direction of the arrow B2, it can be completely guided into the flow guide pipe 22, and prevent the oil dirt from overflowing or deviating from the flow guide pipe 22, so as to ensure that the oil dirt can be completely discharged, and avoid leaking into the inside or outside of the box body 80. Figure 7 As shown, the pipe opening diameter w1 of the end of the flow guide pipe 22 connected to the bottom wall 211 is greater than or equal to the width w2 of the flow guide groove 210 formed in the transverse direction. So that when the oil dirt flows along the bottom wall 211 in the direction of the arrow B2, it can be completely guided into the flow guide pipe 22, and prevent the oil dirt from overflowing or deviating from the flow guide pipe 22, so as to ensure that the oil dirt can be completely discharged, and avoid leaking into the inside or outside of the box body 80.

[0057] In some examples, as shown in FIG. 2, the flow guide pipe 22 comprises a pipe body 221 and a pipe head 222 connected to the pipe body 221. Figure 2 As shown, the pipe opening diameter w1 of the end of the flow guide pipe 22 connected to the bottom wall 211 is greater than or equal to the width w2 of the flow guide groove 210 formed in the transverse direction. So that when the oil dirt flows along the bottom wall 211 in the direction of the arrow B2, it can be completely guided into the flow guide pipe 22, and prevent the oil dirt from overflowing or deviating from the flow guide pipe 22, so as to ensure that the oil dirt can be completely discharged, and avoid leaking into the inside or outside of the box body 80. Figure 5 As shown, the bottom wall 211 is configured with a connecting part 2111 abutting against or partially extending into the bottom end 101 of the heat track 10; the flow guide device 20 further comprises a guide wall 213 downwardly inclined relative to the horizontal plane and arranged on the bottom wall 211 and transversely connected to the side walls 212; the guide wall 213 extends towards the heat track 10 and partially extends over the perpendicular normal line V of the connecting part 2111, and the guide wall 213 and the perpendicular normal line V form an obtuse angle β. Since the connecting part 2111 of the bottom wall 211 abuts against or partially extends into the bottom end 101 of the heat track 10, the oil dirt may, in the process of flowing from the inclined guide part 11 to the bottom wall 211, be caused to flow along the connecting part 2111 and the bottom end 101 of the heat track 10 due to gravity and the like, so as to be guided by the guide wall 213 to flow along the bottom wall 211 to the flow guide pipe 22, and then be discharged out of the heat box 100 through the discharge passage 23, so as to prevent the oil dirt from accumulating in the heat box 100. Figure 5The oil stains falling in the direction of the middle arrow B22 directly fall downward, extend toward the hot rail 10 through the guide wall 213, and partially extend over the vertical normal line V of the connecting portion 2111, so that the oil stains falling downward at the connecting portion 2111 and the bottom end 101 of the hot rail 10 can directly fall on the guide wall 213, and then form an obtuse angle β with the vertical normal line V through the guide wall 213, so that the guide wall 213 can guide the oil stains to flow along the direction of the arrow B23 under the action of gravity. Figure 5 The oil stains flow in the direction of the middle arrow B4 to enter the flow guide pipe 22, and are concentrated and discharged out of the hot box 100 through the flow guide pipe 22. In the process of guiding the oil stains to the flow guide pipe 22 through the guide wall 213, the oil stains flowing on the guide wall 213 can be shielded through the side wall 212, so as to avoid the oil stains escaping from the guide wall 213 to the flow guide groove 210, and avoiding the oil stains leaking into or outside the box body 80.

[0058] In some examples, the oil stains flowing in the direction of the middle arrow B4 flow into the flow guide pipe 22, and are concentrated and discharged out of the hot box 100 through the flow guide pipe 22. Figure 6 As shown, the flow guide wall 21 comprises a bottom wall 211 abutting against or partially extending into the bottom end 101 of the hot rail 10, two opposite side walls 212 extending along the length direction of the bottom wall 211, and a guide wall 213 downwardly inclined relative to the horizontal plane and transversely connecting the side walls 212 and arranged on the bottom wall 211; the side wall 212 extends toward the hot rail 10 and abuts against or partially extends into the bottom end 101 of the hot rail 10, and the bottom wall 211, the side wall 212 and the guide wall 213 jointly constitute a flow guide groove 210 communicating with the flow guide pipe 22, so as to at least discharge the oil stains and / or oil fume out of the hot box 100. By abutting or partially extending into the bottom end 101 of the hot rail 10 through the bottom wall 211 and the side wall 212, the oil stains of the bottom end 101 of the hot rail 10 can flow to the bottom wall 211 and the side wall 212, and the oil stains can be guided to the flow guide groove 210 through the bottom wall 211 and the side wall 212. And the oil stains on the side wall 212 can be intercepted and guided to the flow guide pipe 22 through the guide wall 213, so as to avoid the oil stains escaping from the side wall 212 and leaking into or outside the box body 80.

[0059] In some examples, the oil stains flowing in the direction of the middle arrow B4 flow into the flow guide pipe 22, and are concentrated and discharged out of the hot box 100 through the flow guide pipe 22. Figure 6 As shown, the bottom wall 211 is configured with a connecting portion 2111 abutting against or partially extending into the bottom end 101 of the hot rail 10; the guide wall 213 extends toward the hot rail 10 and partially extends over the vertical normal line V of the connecting portion 2111, and forms an obtuse angle β with the vertical normal line V. Since the connecting portion 2111 of the bottom wall 211 abuts against or partially extends into the bottom end 101 of the hot rail 10, the oil stains flowing from the inclined guide portion 11 to the bottom wall 211 can be caused to flow along the connecting portion 2111 and the bottom end 101 of the hot rail 10 (not shown) due to gravity and other reasons. Figure 6The oil drips directly downwards in the direction indicated by the middle arrow B22, extending through the guide wall 213 towards the hot rail 10 and partially through the vertical normal V of the connecting part 2111. This allows the oil dripping downwards at the connection between the connecting part 2111 and the bottom end 101 of the hot rail 10 to fall directly onto the guide wall 213, so that the guide wall 213 can guide the dripping oil along the direction indicated by gravity. Figure 6 The direction indicated by the middle arrow B4 leads to the guide pipe 22. During the process of the guide wall 213 guiding the oil to the guide pipe 22, the side wall 212 can intercept the oil flowing on the guide wall 213, preventing the oil from escaping from the guide wall 213 to the guide groove 210, and preventing the oil from leaking into the inside or outside of the box 80.

[0060] In some examples, the parameter Figure 5 and Figure 6 As shown, the guide pipe 22 is inclined downward relative to the horizontal plane and disposed on the bottom wall 211. The inner wall 221 of the end of the guide pipe 22 connected to the bottom wall 211 smoothly transitions to the inner wall 2131 of the guide wall 213 facing the hot rail 10. The downward inclination of the guide pipe 22 relative to the horizontal plane allows oil sludge in the guide channel 210 to flow more smoothly into the guide pipe 22, and the guide pipe 22 concentrates and discharges the oil sludge from the hot box 100, avoiding stagnation or accumulation due to oil flow resistance, thus improving oil discharge efficiency. Furthermore, the smooth transition between the inner wall 221 of the pipe opening and the inner wall 2131 of the guide wall 213 facing the hot rail 10 allows oil sludge on the guide wall 213 to flow along the inner wall 2131 to the inner wall 221 of the pipe opening and finally into the guide pipe 22, thus preventing oil overflow or leakage.

[0061] In some examples, the parameter Figure 11 As shown, the sidewall 212 is configured with a positioning portion 24 extending toward the heat rail 10, and the positioning portion 24 is connected to the heat rail 10. By connecting the positioning portion 24 to the heat rail 10 (this state is not shown), the position of the flow guiding device 20 in the heat box 100 is prevented from shifting, allowing the flow guiding device 20 to be stably held in a predetermined position, maintaining the guidance of oil and ensuring the accuracy of discharge. The positioning portion 24 and the heat rail 10 can be connected to each other by welding, plugging, or other methods. For example, the positioning portion 24 can be inserted into a plug-in slot (not shown) constructed in the heat rail 10 to hold the flow guiding device 20 in a predetermined position.

[0062] In some examples, the guide wall 21 is configured with a plurality of positioning holes 2112. In some examples, the parameters... Figures 9 to 11As shown, a number of positioning holes 2112 are formed on one side where the bottom wall 211 extends past the diversion pipe 22 and / or on one side where the side wall 212 extends past the guiding wall 213. The bottom wall 211 is connected and fixed to the hot box 100 by fixing members such as bolts (not shown) passing through the positioning holes 2112 to ensure the stable position of the diversion device 20 and prevent it from moving due to vibration or other factors. In some examples, the positioning holes 2112 may be omitted on the bottom wall 211 and / or the side wall 212, and the diversion device 20 may be installed in the box body 80 and configured below the hot rail 10 by welding, plugging, etc. This application does not limit this.

[0063] In some examples, referring Figure 16 As shown, a triangular connecting plate 27 as shown in Figure 16 is filled and formed between the part of the guiding wall 213 extending out of the side wall 212 and the side wall 212 to intercept and guide the oil stain dripping onto the guiding wall 213 from the bottom end 111 of the inclined guiding part 11 along the Figure 16 direction of the arrow B22 shown in

[0064] Based on any of the technical solutions of the diversion device 20 disclosed in the foregoing embodiments and their reasonable combinations, this embodiment also discloses a hot rail device 1, which is configured inside the hot box 100.

[0065] Referring Figure 3 and Figure 4 As shown, the hot rail device 1 includes: a hot rail 10, and the bottom end 101 of the hot rail 10 is configured with the diversion device 20 disclosed in the foregoing embodiments; at least part of the bottom end 101 of the hot rail 10 is constructed with an inclined guiding part 11 that extends obliquely downward relative to the horizontal plane, and one end 2111 of the diversion wall 21 close to the hot rail 10 abuts against the inclined guiding part 11 or partially extends into the inclined guiding part 11, so that the oil stain can be guided from the inclined guiding part 11 to the diversion pipe 22 by the diversion wall 21. The inclined guiding part 11 is formed along the length direction of the hot rail 10 and close to the bottom end 101 of the diversion device 20.

[0066] The oil stain flowing naturally along the hot rail 会聚至倾斜导引部11,油污沿倾斜导引部11的倾斜方向(如 Figure 4 中箭头B1所示方向)流动,通过导流壁21靠近热轨10的一端抵靠于倾斜导引部11或者部分延伸入倾斜导引部11,以使汇聚至热轨10的底端101的油污能够沿倾斜导引部11向导流壁21流动,通过导流壁21引导油污进入导流槽210,并通过导流槽210相对于水平面向下倾斜,以引导油污在导流壁21上沿如 Figure 4 It should be noted that there is an unclear expression "油污沿倾斜导引部11的倾斜方向(如 Figure 4 中箭头B1所示方向)流动,通过导流壁21靠近热轨10的一端抵靠于倾斜导引部11或者部分延伸入倾斜导引部11,以使汇聚至热轨10的底端101的油污能够沿倾斜导引部11向导流壁21流动,通过导流壁21引导油污进入导流槽210,并通过导流槽210相对于水平面向下倾斜,以引导油污在导流壁21上沿如 " in the original text. The translation is based on the best understanding of the context, but this part may need further clarification for a more accurate translation.flows in the direction indicated by the middle arrow B2, thereby guiding the oil stains to flow along the flow guide wall 21 to the flow guide pipe 22, so that the oil stains flow in the flow guide pipe 22 along the direction indicated by the arrow B1. Figure 4 flows in the direction indicated by the middle arrow B3, so as to discharge the oil stains in the heat box 100 through the discharge channel 23, preventing the oil stains from dripping from the bottom end 101 of the heat rail 10 at the gap between the heat rail 10 and the door plate 801. The heat rail device 1 disclosed in the present application collects the oil stains gathered at the bottom end 101 of the heat rail 10 through the flow guide device 20 and discharges the oil stains out of the heat box 100, thereby effectively avoiding the pollution of the ground by the dripping high-temperature oil drops and avoiding the personal injury of the operators in the operation channel of the false twist texturing machine caused by the dripping high-temperature oil drops.

[0067] In some examples, the heat rail device 1 further comprises a flow guide device 20. Figure 4 As shown, a smoke exhaust pipe 70 is arranged below the heat box 100, the smoke exhaust pipe 70 is connected to the flow guide pipe 22 included in the flow guide device 20, and the smoke exhaust pipe 70 is in communication with the discharge channel 23. The smoke exhaust pipe 70 can be externally connected to a negative pressure source, and the negative pressure source forms a suction force on the inside of the heat box 100 through the smoke exhaust pipe 70 and the discharge channel 23, so as to discharge the oil fume in the heat box 100 and / or the oil stains collected by the flow guide device 20 out of the heat box 100 through the flow guide device 20, thereby improving the working efficiency of discharging the oil stains and / or the oil fume and reducing the suction power consumption.

[0068] The heat rail device 1 disclosed in the present application collects the oil stains gathered at the bottom end 101 of the heat rail 10 through the flow guide device 20 and discharges the oil stains out of the heat box 100, thereby eliminating the need for continuous high-intensity oil fume suction and discharge operation on the heat box 100, reducing the demand of the heat box 100 on the suction and discharge volume of the negative pressure source. Even if the smoke exhaust pipe 70 below the heat box 100 is not connected to the negative pressure source, the oil stains at the bottom end 101 of the heat rail 10 can flow into the smoke exhaust pipe 70 through the flow guide device 20 under the action of gravity, thereby being discharged out of the heat box 100, thereby reducing the heat loss in the heat box 100 caused by the oil fume suction and discharge operation, reducing energy waste, and achieving the purpose of energy saving and consumption reduction of the heat box 100 and the false twist texturing machine including the heat box 100.

[0069] In some examples, the heat rail device 1 further comprises a flow guide device 20. Figure 8 As shown, the bottom end 101 of the heat rail 10 is partially configured as an inclined guide part 11a extending downwardly inclined relative to the horizontal plane. Figure 17 As shown, the bottom end 101 of the heat rail 10 is partially configured as an inclined guide part 11a extending downwardly inclined relative to the horizontal plane. Figure 13 As shown, the bottom end 101 of the heat rail 10 is partially configured as an inclined guide part 11a extending downwardly inclined relative to the horizontal plane.

[0070] In some examples, the heat rail device 1 further comprises a flow guide device 20. Figure 8 As shown, the bottom end 101 of the heat rail 10 is partially configured as an inclined guide part 11a extending downwardly inclined relative to the horizontal plane. Figure 13As shown, the inclined guide part 11 extends downwardly relative to the horizontal plane H, and forms an acute angle a1 with the horizontal plane H. The angle of the acute angle a1 is adjusted to adjust the flow direction and flow rate of the oil stains. The greater the angle of the acute angle a1, the stronger the gravity force of the oil stains along the inclined guide part 11, so that the flow speed of the oil stains on the inclined guide part 11 is faster, thereby improving the discharge efficiency and avoiding stagnation and accumulation of the oil stains on the inclined guide part 11. Preferably, the acute angle a1 is greater than or equal to 15° and less than or equal to 75°.

[0071] In some examples, the inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 3 The inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 12 As shown, the heating track 10 is provided with a plurality of heating fiber grooves 12 formed along the length direction of the heating track 10, and groove walls 13 formed on both sides of the grooves 12. The inclined guide part 11 extends to the bottom end (not shown) of the heating track 10 along the length direction of the heating track 10, and forms a flow guide part 112 extending to the bottom end 121 of the groove 12. The flow guide wall 21 abuts against the flow guide part 112 or partially extends into the flow guide part 112. In the process of heating the fiber N by the heating box 100, the oil mist contained in the oil fume adheres to the surfaces of the groove walls 13 and the grooves 12 and gradually forms oil stains. The oil stains on the surfaces of the groove walls 13 and the grooves 12 naturally flow along the inclined direction of the heating track 10 under the action of gravity, converge to the inclined guide part 11, flow through the flow guide part 112 to the flow guide wall 21, and are finally discharged out of the heating box 100 through the flow guide device 20.

[0072] In some examples, the inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 8 The inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 17 As shown, the inclined guide part 11 forms a flow guide part 112a extending to the bottom end 121 of the groove 12, and the flow guide wall 21 (i.e., the bottom wall 211 and / or the side wall 212) abuts against or partially extends into any position of the flow guide part 112a. This enables the flow guide wall 21 to effectively receive the oil stains flowing along the inclined guide part 11.

[0073] In some examples, the inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 13 As shown, the inclined guide part 11 forms a flow guide part 112b extending to the bottom end 121 of the groove 12, and the flow guide wall 21 (i.e., the bottom wall 211 and / or the side wall 212) abuts against or partially extends into any position of the flow guide part 112b. This enables the flow guide wall 21 to effectively receive the oil stains flowing along the inclined guide part 11.

[0074] In some examples, the inclined guide part 11 is arranged to extend along the length direction of the heating track 10. Figure 4 As shown, to avoid the flow guide wall 21 interfering with the movement path M of the fiber N, preferably, the flow guide wall 21 (i.e., the bottom wall 211) abuts against or partially extends into the bottom end 111 of the flow guide part 112a along the inclined direction of the flow guide part 112a (i.e., the bottom end of the inclined guide part 11).

[0075] In some examples, the parameter Figure 12 As shown, the guide wall 21 is transverse (i.e. Figure 12 The width w3 formed in the direction indicated by the X-axis is greater than the lateral width w4 between the channel walls 13 on both sides of the channel 12. In some examples, the lateral width w3 of the guide wall 21 includes the width w2 formed laterally by the guide channel 210, so that the guide channel 210 can fully receive the oil sludge at the bottom end 101 of the hot rail 10, preventing oil sludge from leaking into the inside or outside of the housing 80. In some examples, the lateral width w3 of the guide wall 21 includes the width of the bottom wall 211 that abuts against the bottom end 101 of the hot rail 10 or partially extends into the bottom end 101 of the hot rail 10, so that the bottom wall 211 can fully receive the oil sludge flowing from the bottom end 101 of the hot rail 10 to the guide wall 21, preventing oil sludge from leaking into the inside or outside of the housing 80. In some examples, the lateral width w3 of the flow guide wall 21 includes the overall width of the bottom wall 211 and side wall 212 that abut against the bottom end 101 of the hot rail 10 or partially extend into the bottom end 101 of the hot rail 10, so that the bottom wall 211 and side wall 212 can fully receive the oil flowing from the bottom end 101 of the hot rail 10 into the flow guide wall 21, and prevent the oil from leaking into the inside or outside of the housing 80.

[0076] In some examples, the tilt guide 11 is configured as at least one of a plane or a curved surface. (See reference...) Figure 8 or Figure 13 As shown, the cross-sectional shape formed by cutting the inclined guide section 11 along the Z-axis is a plane 11a, 11a' that is inclined downward relative to the horizontal plane, or, refer to Figure 14 or Figure 15 As shown, the cross-sectional shape formed by cutting the inclined guide portion 11 along the Z-axis is a curved surface 11b that curves downward relative to the horizontal surface, or even a combination of a curved surface and a plane (this state is not shown). The inclined guide portion 11 can also be other shapes that can guide the oil flow to the guide wall 21, and this application does not limit this.
