[0028] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0029] It should be noted that the accompanying drawings (e.g., ...) included in this application... Figures 2 to 4 , Figures 6 to 9 All of them are Figure 3 A sectional view or partial sectional view formed by cutting the Z-axis of the hot box 100.

[0030] In the process of performing heat treatment on chemical fibers (e.g., pre-draft yarn) in a heat box, the chemical fibers are decomposed at high temperature or the additives added in the process of processing the chemical fibers volatilize in the high-temperature environment formed in 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 to form a negative pressure in the heat box (i.e., the space region formed between the heat rail 10 and the door plate 801) to exhaust the oil fume from the heat box. However, since the negative pressure source is difficult to completely and timely suck out the oil fume volatilized in the heat box, with the increase of the use time, the oil mist contained in the oil fume adheres to the heat rail and gradually accumulates to form oil stains. Since the heat box is usually installed obliquely in the false twist texturing machine, the heat rail is oblique with the heat box, and the oil stains on the heat rail naturally flow along the oblique direction of the heat rail under the action of gravity, converge to the bottom end of the heat rail along the length direction of the heat rail, and cause the oil stains to drip from the gap between the heat rail and the door plate at the bottom end of the heat rail.

[0031] In particular, in order to inhibit 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, and causing energy waste.

[0032] The heat box 100 in the present application can be understood as a texturing heat box configured in a false twist texturing machine (not shown), or, for example, a biphenyl heating method is used to perform heat treatment on the chemical fibers 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.

[0033] In some examples, referring to Figure 3 As shown, the box body 80 is the shell of the heat box 100, used to accommodate the heat rail 10 and the flow guide device 20 with flow guide grooves (hereinafter referred to as "flow guide device 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. Since the heat box 100 is obliquely installed in the false twist texturing machine, the heat rail 10 is oblique with the heat box 100, and thus the heat rail 10 has a certain oblique angle relative to the horizontal plane, for example, 50°, 55°, 60°, etc. Thus, the oil stains can naturally flow along the oblique 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 of the heat rail 10.

[0034] Referring to Figure 3 With Figure 4 And Figure 10As shown, the flow guiding device 20 disclosed in this application abuts against the bottom end 101 of the heat rail 10 included in the heat box 100 along its length. The bottom end 101 of the heat rail 10 is at least partially configured with an inclined guide portion 11 extending toward the flow guiding device 20. Oil flowing naturally along the inclined direction of the heat rail 10 converges to the inclined guide portion 11. The oil flows along the inclined direction of the inclined guide portion 11 (e.g., ...). Figure 4 The oil flows in the direction indicated by the middle arrow B1, abutting against the bottom end 101 of the hot rail 10 (i.e., the inclined guide portion 11) through the bottom wall 211 or partially extending into the bottom end 101 of the hot rail 10, so that the oil converging at the bottom end 101 of the hot rail 10 can flow along the inclined guide portion 11 towards the bottom wall 211, and be guided by the bottom wall 211 into the guide channel 210, and then by the guide channel 210 being inclined downward relative to the horizontal surface, so as to guide the oil along the bottom wall 211. Figure 4 The oil flows in the direction indicated by the middle arrow B2, thereby guiding the oil sludge along the bottom wall 211 to the guide pipe 213, so that the oil sludge flows along the guide pipe 213 as shown by the middle arrow B2. Figure 4 The oil flows in the direction indicated by the middle arrow B3 to discharge the oil contaminants into the hot box 100 through the discharge channel 215, preventing oil contaminants from dripping from the bottom of the hot rail 10 through the gap between the hot rail 10 and the door panel 801. The flow guiding device 20 disclosed in this application can collect the oil contaminants gathered at the bottom 101 of the hot rail 10 and discharge the oil contaminants into the hot box 100, thereby effectively preventing the dripping high-temperature oil droplets from contaminating the ground and preventing the dripping high-temperature oil droplets from causing personal injury to the operators in the working channel of the false twisting deformation machine.

[0035] In some examples, the parameter Figure 4 As shown, a smoke exhaust pipe 70 is provided below the hot box 100, and the smoke exhaust pipe 70 is connected to the guide pipe 213 included in the guide device 20. The smoke exhaust pipe 70 can be connected to an external negative pressure source. The negative pressure source forms a suction force on the inside of the hot box 100 through the smoke exhaust pipe 70 and the guide pipe 213, so as to discharge the oil fumes and / or oil stains collected by the guide device 20 from the hot box 100. This can improve the working efficiency of discharging oil stains and / or oil fumes and reduce suction power consumption. The flow guiding device 20 disclosed in this application collects the oil sludge gathered at the bottom 101 of the hot rail 10 and discharges it from the hot box 100. This eliminates the need for continuous, high-intensity oil fume extraction from the hot box 100, reducing the demand for exhaust airflow from the negative pressure source. Furthermore, the exhaust pipe 70 connected to the flow guiding device 20 below the hot box 100 does not need to be connected to the negative pressure source. This reduces heat loss from the hot box 100 and the false-twist texturing machine (not shown) containing the hot box 100, thus reducing energy waste and achieving energy conservation and consumption reduction. The energy consumption to be reduced in this application can be considered as the energy consumption generated by the hot box 100 containing the hot rail 10, or as the energy consumption generated by the entire false-twist texturing machine containing the hot box 100, or as the energy consumption generated jointly by the false-twist texturing machine and the negative pressure source.

[0036] Reference Figure 1 、 Figure 2 and Figure 4 As shown, the flow guiding device 20 includes: a bottom wall 211 inclined downward with respect to the horizontal plane, the bottom wall 211 abuts against the bottom end 101 of the hot rail 10 or partially extends 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 flow guiding pipe 213 connected to the bottom wall 211; the bottom wall 211 and the side walls 212 together form a flow guiding groove 210 communicating with the flow guiding pipe 213, and the flow guiding groove 210 and the flow guiding pipe 213 together form a discharge channel 215 for discharging oil stains and / or oil fumes from the hot box 100. During the process of the hot box 100 performing a heating treatment on the chemical fiber N, the oil stains on the hot rail 10 naturally flow along the inclined direction of the hot rail 10 under the action of gravity and converge towards the bottom end 101 of the hot rail 10. The oil stains flow towards the bottom wall 211 along the direction shown by the arrow B1 in Figure 4 Since the bottom wall 211 abuts against the bottom end 101 of the hot rail 10 (i.e., the inclined guiding portion 11) or partially extends into the bottom end 101 of the hot rail 10, the oil stains can flow along the inclined guiding portion 11 along the direction shown by the arrow B2 in Figure 4 to the bottom wall 211, and the bottom wall 211 guides the oil stains to flow along the direction shown by the arrow B3 in Figure 4 to the flow guiding pipe 213, and then the oil stains are discharged from the inside of the hot box 100 through the discharge channel 215. The two opposite side walls 212 form the boundary of the flow guiding groove 210 to maintain the flow path of the oil stains in the flow guiding groove 210, ensure that the oil stains flow from the bottom wall 211 to the flow guiding pipe 213, and avoid leakage caused by deviating from the flow path.

[0037] In some examples, reference Figure 4 As shown, the discharge channel 215 is jointly formed by the flow guiding groove 210 and the flow guiding pipe 213 to provide a continuous and smooth flow path for the oil stains. The bottom wall 211 which is inclined downward as a whole provides power for the oil stains to flow naturally to the lowest point. Under the action of gravity, the oil stains flow along the inclined surface of the bottom wall 211 to the flow guiding pipe 213 and are discharged from the hot box 100 through the flow guiding pipe 213, avoiding the accumulation or leakage of the oil stains in the hot box 100 to achieve smooth discharge of the oil stains. The discharge channel 215 can also be used to discharge the oil fumes from the hot box 100. When a smoke exhaust pipe 70 communicating with the discharge channel 215 is provided in the hot box 100 and the smoke exhaust pipe 70 is externally connected to a negative pressure source, the negative pressure source forms a suction force on the inside of the hot box 100 through the smoke exhaust pipe 70 and the discharge channel 215, so as to discharge the oil fumes and / or the oil stains collected by the flow guiding device 20 in the hot box 100 from the hot box 100 through the discharge channel 215. Thereby, the working efficiency of discharging the oil stains and / or the oil fumes can be improved, and the suction power consumption can be reduced.

[0038] In some examples, the parameter Figure 4 As shown, the bottom wall 211 slopes downward relative to the horizontal plane H, and the extension direction E of the bottom wall 211 forms an acute angle α with the horizontal plane H. By adjusting the angle α, the flow direction and velocity of the oil are adjusted. Without interfering with the movement path M of the synthetic fiber N, the larger the angle α, the stronger the component of gravity that causes the oil to flow along the bottom wall 211, thus increasing the flow velocity of the oil on the bottom wall 211 and improving discharge efficiency, while preventing the oil from stagnating and accumulating on the bottom wall 211. Preferably, the acute angle α is greater than or equal to 30° and less than or equal to 60°.

[0039] In some examples, the configuration of the bottom wall 211 abutting against the bottom end 101 of the hot rail 10 or partially extending into the bottom end 101 of the hot rail 10 can achieve the purpose of guiding the oil stains from the tilting guide 11 along... Figure 4 The flow proceeds in the direction indicated by the middle arrow B2 to the bottom wall 211. Among these, the reference... Figure 4 As shown, the bottom wall 211 abuts against the bottom end 101 of the heat rail 10, directly contacting and tightly adhering to the bottom end 101 of the heat rail 10, and is tightly connected to the bottom end 101 of the heat rail 10. This allows oil contaminants at the bottom end 101 of the heat rail 10 to flow along the inclined guide portion 11 to the bottom wall 211, and then along the bottom wall 211 to the guide pipe 213, so that the oil contaminants are discharged from the heat box 100 through the discharge channel 215. Part of the bottom wall 211 extends into the bottom end 101 of the heat rail 10 (this state is not shown), making the joint between the bottom wall 211 and the bottom end 101 of the heat rail 10 more compact, reducing potential gaps, preventing oil contaminants from leaking as they flow along the inclined guide portion 11 to the bottom wall 211, and reducing the risk of contamination of the external working area of ​​the heat box 100.

[0040] In some examples, the parameter Figure 4 As shown, the guide pipe 213 is inclined downward relative to the horizontal plane on the bottom wall 211. This allows the oil in the guide groove 210 to flow more smoothly into the guide pipe 213 along the bottom wall 211 under the action of gravity, and flow along the inner wall of the guide pipe 213, so as to concentrate the oil and discharge it from the heat box 100, thereby avoiding stagnation or accumulation caused by the flow resistance of the oil and improving the oil discharge efficiency.

[0041] In some examples, the parameter Figure 5 As shown, the diameter w1 of the pipe opening formed laterally at one end of the guide pipe 213 connected to the bottom wall 211 is greater than or equal to the width w2 formed laterally on the guide groove 210. This is to allow the oil to flow along the bottom wall 211. Figure 4 When the flow is in the direction indicated by the middle arrow B2, it can be completely guided into the guide pipe 213 to prevent oil from overflowing or deviating from the guide pipe 213, ensuring that the oil can be completely discharged and avoiding oil leakage into the inside or outside of the housing 80.

[0042] In some examples, the parameter Figure 1 participates Figure 2 As shown, the side wall 212 is constructed with a positioning portion 214 extending towards the hot rail 10, and the positioning portion 214 is interconnected with the hot rail 10 (this state is not shown). By interconnecting the positioning portion 214 with the hot rail 10, the position of the diversion device 20 in the hot box 100 is prevented from shifting, enabling the diversion device 20 to be stably maintained at a predetermined position, maintaining the guidance of the oil stain and ensuring the accuracy of discharge. The positioning portion 214 and the hot rail 10 can be interconnected by means such as welding and plugging. For example, the positioning portion 214 can be inserted into a plugging groove (not shown) constructed in the hot rail 10 to maintain the diversion device 20 at a predetermined position.

[0043] In some examples, a plurality of positioning holes 2112 are constructed on one side where the bottom wall 211 and / or the side wall 212 extend beyond the diversion pipe 213. For example, Figure 4 As shown, a plurality of positioning holes 2112 are constructed on one side where the bottom wall 211 extends beyond the diversion pipe 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 can also be omitted on the bottom wall 211 and / or the side wall 212, and the diversion device 20 can be installed in the box body 80 by means such as welding and plugging and abutted against the bottom end 101 of the hot rail 10. This application makes no limitation thereto.

[0044] Based on any of the above 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.

[0045] Refer Figure 3 to Figure 4 As shown, the hot rail device 1 includes: a hot rail 10, and a diversion device 20 configured at the bottom end 101 of the hot rail 10 as disclosed in the above embodiments; at least part of the bottom end 101 of the hot rail 10 is constructed with an inclined guiding portion 11 extending obliquely downward with respect to the horizontal plane, and one end 2111 of the bottom wall 211 close to the hot rail 10 abuts against the inclined guiding portion 11 or partially extends into the inclined guiding portion 11, so that the bottom wall 211 guides the oil stain from the inclined guiding portion 11 to the diversion pipe 213. The inclined guiding portion 11 is formed along the length direction of the hot rail 10 and close to the bottom end 101 of the diversion device 20.

[0046] The oil stain flowing naturally along the hot rail 10 converges to the inclined guiding portion 11, and the oil stain flows along the inclined direction of the inclined guiding portion 11 (such as Figure 4The oil dirt gathered at the bottom end 101 of the heat rail 10 flows in the direction indicated by the arrow B1, and is guided to flow along the bottom wall 211 by the inclined guide part 11 or the part extending into the inclined guide part 11 at one end 2111 of the bottom wall 211 close to the heat rail 10, so that the oil dirt gathered at the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the bottom wall 211, and is guided to flow into the flow guide groove 210 through the bottom wall 211, and is guided to flow downward relative to the horizontal plane through the flow guide groove 210, so as to guide the oil dirt to flow along the bottom wall 211 as indicated by the arrow B2, and is guided to flow along the bottom wall 211 to the flow guide pipe 213, so that the oil dirt flows in the flow guide pipe 213 as indicated by the arrow B3. Figure 4 The oil dirt gathered at the bottom end 101 of the heat rail 10 flows in the direction indicated by the arrow B1, and is guided to flow along the bottom wall 211 by the inclined guide part 11 or the part extending into the inclined guide part 11 at one end 2111 of the bottom wall 211 close to the heat rail 10, so that the oil dirt gathered at the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the bottom wall 211, and is guided to flow into the flow guide groove 210 through the bottom wall 211, and is guided to flow downward relative to the horizontal plane through the flow guide groove 210, so as to guide the oil dirt to flow along the bottom wall 211 as indicated by the arrow B2, and is guided to flow along the bottom wall 211 to the flow guide pipe 213, so that the oil dirt flows in the flow guide pipe 213 as indicated by the arrow B3. Figure 4 The oil dirt gathered at the bottom end 101 of the heat rail 10 flows in the direction indicated by the arrow B1, and is guided to flow along the bottom wall 211 by the inclined guide part 11 or the part extending into the inclined guide part 11 at one end 2111 of the bottom wall 211 close to the heat rail 10, so that the oil dirt gathered at the bottom end 101 of the heat rail 10 can flow along the inclined guide part 11 to the bottom wall 211, and is guided to flow into the flow guide groove 210 through the bottom wall 211, and is guided to flow downward relative to the horizontal plane through the flow guide groove 210, so as to guide the oil dirt to flow along the bottom wall 211 as indicated by the arrow B2, and is guided to flow along the bottom wall 211 to the flow guide pipe 213, so that the oil dirt flows in the flow guide pipe 213 as indicated by the arrow B3.

[0047] In some examples, the heat rail device 1 further comprises a flow guide device 20. Figure 4 As shown, the heat box 100 is provided below with an exhaust pipe 70 connected to the flow guide pipe 213 of the flow guide device 20, and the exhaust pipe 70 is in communication with the exhaust channel 215. The exhaust pipe 70 can be connected to a negative pressure source, and the negative pressure source forms a suction force in the heat box 100 through the exhaust pipe 70 and the exhaust channel 215, so as to exhaust the oil fume in the heat box 100 and / or the oil dirt collected by the flow guide device 20 from the heat box 100 through the flow guide device 20, thereby improving the working efficiency of exhausting the oil fume and / or the oil dirt and reducing the suction power consumption.

[0048] The heat rail device 1 disclosed in the present application collects the oil dirt gathered at the bottom end 101 of the heat rail 10 through the flow guide device 20 and exhausts the oil dirt from the heat box 100, so that the heat box 100 does not need to be continuously operated at high strength for oil fume exhaust, thereby reducing the demand of the heat box 100 on the exhaust volume of the negative pressure source, and even the exhaust pipe 70 connected to the flow guide device 20 below the heat box 100 does not need to be connected to the negative pressure source, thereby reducing the heat loss in the heat box 100 and the false twist texturing machine (not shown) comprising the heat box 100, reducing energy waste, and achieving the purpose of energy saving and consumption reduction.

[0049] In some examples, the heat rail device 1 further comprises a flow guide device 20. Figure 6 As shown, the heat rail device 1 further comprises a flow guide device 20. Figure 10 As shown, the bottom end 101 of the heat rail 10 is partially configured with an inclined guide part 11a extending downward relative to the horizontal plane. Figure 7 As shown, the bottom end 101 of the heat rail 10 is partially configured with an inclined guide part 11a extending downward relative to the horizontal plane. As shown, the bottom end 101 of the heat rail 10 is partially configured with an inclined guide part 11a extending downward relative to the horizontal plane.

[0050] In some examples, the parameter Figure 6 and Figure 7 As shown, the inclined guide section 11 extends downward at an angle relative to the horizontal plane H, forming an acute angle α1 with the horizontal plane H. By adjusting the angle α1, the flow direction and velocity of the oil are adjusted. The larger the angle α1, the stronger the component of gravity acting on the oil along the inclined guide section 11, thus making the oil flow faster on the inclined guide section 11, thereby improving the discharge efficiency and preventing the oil from stagnating and accumulating in the inclined guide section 11. Preferably, the acute angle α1 is greater than or equal to 15° and less than or equal to 75°.

[0051] In some examples, the parameter Figure 3 and Figure 5 and Figure 10 As shown, the heating rail 10 has several channels 12 formed along its length to heat the synthetic fibers, and channels 13 are formed on both sides of the channels 12. An inclined guide portion 11 extends through the bottom end of the channels 12 and the channels 13 along the length of the heating rail 10, forming a guide portion 112 extending through the bottom end of the channels 12. The bottom wall 211 abuts against the guide portion 112 or partially extends into the guide portion 112. The channels 12 extend from the bottom end 121 along the length of the heating rail 10 to the inclined guide portion 11, and the channels 13 extend from the bottom end 131 along the length of the heating rail 10 to the inclined guide portion 11. During the heating process of chemical fiber N in the hot box 100, the oil mist contained in the oil fume adheres to the surface of the tank wall 13 and the channel 12 and gradually forms oil stains. The oil stains on the surface of the tank wall 13 and the channel 12 flow naturally along the inclined direction of the hot rail 10 under the action of gravity and converge towards the inclined guide part 11. The oil stains flow through the guide part 112 to flow towards the bottom wall 211, and finally are discharged from the hot box 100 through the guide device 20.

[0052] In some examples, the parameter Figure 6 and Figure 10 As shown, the inclined guide portion 11 forms a guide portion 112a extending through the bottom end 121 of the channel 12, and the bottom wall 211 abuts against or partially extends into any position of the guide portion 112a. This allows the bottom wall 211 to effectively receive oil flowing along the inclined guide portion 11.

[0053] In some examples, the parameter Figure 7 As shown, the inclined guide portion 11 forms a guide portion 112b extending through the bottom end 121 of the channel 12, and the bottom wall 211 abuts against or partially extends into any position of the guide portion 112b. This allows the bottom wall 211 to effectively receive oil flowing along the inclined guide portion 11.

[0054] In some examples, the parameter Figure 4 and Figure 10As shown, in order to avoid the bottom wall 211 interfering with the moving path M of the fiber N, preferably, the bottom wall 211 abuts against the bottom end 111 of the flow guide portion 112 along the inclined direction thereof (i.e., the bottom end of the inclined guide portion 11) or partially extends into the bottom end 111 of the flow guide portion 112.

[0055] In some examples, the inclined guide portion 11 is configured to be at least one of a plane or a curved surface. Figure 5 As shown, the bottom wall 211 is formed with a width w3 in the transverse direction (i.e., the direction indicated by the X-axis) that is greater than the transverse width w4 between the groove walls 13 on both sides of the channel 12. This allows the bottom wall 211 to sufficiently receive the oil stains flowing along the inclined guide portion 11, avoiding leakage of the oil stains to the inside or outside of the cabinet 80. Figure 5

[0056] In some examples, the inclined guide portion 11 is configured to be at least one of a plane or a curved surface. Figure 6 Alternatively, Figure 7 As shown, the cross-sectional shape of the inclined guide portion 11 formed by cutting along the Z-axis is a plane 11a, 11a' that is downwardly inclined relative to the horizontal plane, or alternatively, Figure 8 Alternatively, Figure 9 As shown, the cross-sectional shape of the inclined guide portion 11 formed by cutting along the Z-axis is a curved surface 11b that is downwardly curved relative to the horizontal plane, 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 flow of oil stains to the bottom wall 211, which are not limited by the present application.
