Description

Technical Field

[0001] This application relates to the technical field of chemical fiber production equipment, and in particular to a spinning ring blowing lifting device. Background Technology

[0002] In the process of chemical fiber production, spinning is an important step, which requires the use of a ring blower. Cooling air is blown from the circumference towards the fine stream of melt ejected from the spinneret orifice, so that the fine stream is cooled and solidified into fibers evenly. This method is suitable for spinning cooling when there are many spinneret orifices.

[0003] In the existing technology, the ring blower equipment includes a ring blower for spinning yarn and a lifting component that drives the ring blower to rise and fall. The top and bottom of the ring blower are respectively provided with a feed inlet and a discharge outlet. The lifting component that drives the ring blower to rise and fall is usually a cylinder, and the air supply equipment for the cylinder is usually an air compressor. If the air compressor fails, the ring blower will fall, and production must be stopped on site. Production can only be resumed after the air compressor is repaired. However, this will cause a large amount of waste yarn, so further improvement is needed. Utility Model Content

[0004] To address the above problems, this application provides a spinning ring blowing lifting device.

[0005] This application provides a spinning ring blowing lifting device, which adopts the following technical solution:

[0006] A spinning ring blowing lifting device includes a cylinder for supporting the ring blowing tube, an air inlet pipe fixedly inserted through the cylinder, and an air compressor connected to the air inlet pipe to supply air to the cylinder. A shut-off valve is provided on the air inlet pipe.

[0007] By adopting the above technical solution, when the air compressor malfunctions, a shut-off valve installed on the intake pipe cuts off the air supply, preserving the previously supplied air pressure within the cylinder. This effectively maintains the air pressure in the ring blower for a certain period, buying time for repairs and preventing direct production interruption during air compressor maintenance. This is suitable for emergency scenarios. Furthermore, by incorporating a shut-off valve, it offers advantages in terms of lower cost and simpler structure compared to existing backup air compressors or large-capacity air tank solutions.

[0008] Preferably, a pressure sensor is provided on the shut-off valve.

[0009] By adopting the above technical solution, and further installing a pressure sensor on the shut-off valve on the intake pipe, this solution can monitor the pressure status inside the cylinder in real time and ensure that the pressure is kept within a safe and effective range.

[0010] Preferably, the intake pipe includes a first intake pipe connected to the air compressor and a second intake pipe connected to the cylinder. The shut-off valve is disposed between the first and second intake pipes. The outer peripheral walls of the first and second intake pipes are provided with first flanges. The two ends of the shut-off valve are provided with second flanges. A sealing element is disposed between the first and second flanges. The ends of the first and second intake pipes that are close to each other or the two ends of the shut-off valve have protruding insertion portions for insertion into the sealing element and abutting against the sealing element. A connecting element is disposed between the first and second flanges.

[0011] By adopting the above technical solution, the sealing performance between the stop valve added to the intake pipe and the intake pipe needs to be improved during installation. To this end, the design of the fit between the first flange, the second flange and the sealing element further improves the sealing performance at the connection, ensuring effective pressure maintenance. As the connecting element connects the first flange and the second flange, it squeezes the sealing element, thereby improving the sealing effect.

[0012] Preferably, the seal is elastic, the seal is coaxially sleeved on the insertion part, the diameter of the insertion part is smaller than the inner diameter of the first air inlet pipe and the second air inlet pipe, or smaller than the inner diameter of the ports at both ends of the shut-off valve, and the outer peripheral wall of the seal is provided with a first inclined surface inclined towards the insertion part.

[0013] By adopting the above technical solution, the seal is elastic and can tightly fit the insertion part, effectively reducing gas leakage and improving pressure holding effect. The seal is coaxially sleeved on the insertion part, ensuring assembly accuracy and sealing performance. The diameter of the insertion part is smaller than the inner diameter of the first and second air inlet pipes or the inner diameter at the shut-off valve port, forming a stepped structure, further enhancing sealing reliability. The first inclined surface on the outer peripheral wall of the seal can automatically adjust the contact area under force, improving sealing adaptability, thereby better maintaining the pressure inside the cylinder and extending emergency time in the event of air compressor failure.

[0014] Preferably, the inner peripheral walls of the first and second air intake pipes that are close to each other or the two ends of the shut-off valve are provided with a second inclined surface that is slidably connected to the first inclined surface.

[0015] By adopting the above technical solution, the inner peripheral walls of the first and second air inlet pipes that are close to each other or the two ends of the shut-off valve are provided with a second inclined surface that slides and connects with the first inclined surface of the seal. This allows the seal to be positioned and assembled more smoothly during installation, while enhancing the tightness of the seal with the air inlet pipe or shut-off valve, thereby further improving the overall sealing effect and reducing the possibility of gas leakage.

[0016] Preferably, the inner peripheral wall of the seal is provided with a second sealing ring at the middle part.

[0017] By adopting the above technical solution, the second sealing ring set on the inner circumferential wall of the middle part of the seal can further improve the sealing effect and effectively prevent gas leakage.

[0018] Preferably, the sealing element has a large outer diameter end and a small outer diameter end, depending on its own diameter. The first flange or the second flange protrudes with a limiting part, and the end face of the sealing element at the large end is provided with a slot for the limiting part to slide and insert.

[0019] By adopting the above technical solution, the seal, with its large and small ends and a slot on the large end face to engage with the limiting part of the first or second flange, effectively prevents circumferential rotation or axial displacement during installation, thereby improving the installation stability of the seal. This design further enhances the sealing performance between the intake pipe and the shut-off valve, ensuring that the pressure inside the ring blower is effectively maintained during air compressor failures, extending production time in emergency scenarios.

[0020] Preferably, a first sealing ring is provided between the first flange and the second flange.

[0021] By adopting the above technical solution, a first sealing ring is set between the first flange and the second flange. In conjunction with the set sealing element and the second sealing ring, the sealing performance of the connection can be further improved and the possibility of gas leakage can be reduced.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. By installing a shut-off valve on the air intake pipe, the pressure inside the cylinder can be effectively maintained when the air compressor fails, preventing the ring blower from falling down, thereby reducing production interruption time and reducing waste wire generation;

[0024] 2. A sealing element is installed between the shut-off valve and the air inlet pipe, which significantly improves the pressure holding effect of the system and extends the pressure holding time, making it suitable for short-term fault maintenance in emergency scenarios.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail below.

[0032] This application discloses a spinning ring blowing lifting device.

[0033] Example 1:

[0034] A spinning ring blowing lifting device, as described in the reference Figure 1 , Figure 2 It includes a cylinder 2 for supporting the ring blower 1, an air inlet pipe 3 fixedly inserted through the cylinder 2, and an air compressor 4 connected to the air inlet pipe 3 to supply air to the cylinder 2. The air inlet pipe 3 is equipped with a shut-off valve 5, which achieves the effect of maintaining the stable state of the ring blower 1 in the short term when the air compressor 4 fails.

[0035] Reference Figure 2 , Figure 3 Specifically, the intake pipe 3 includes a first intake pipe 31 connected to the air compressor 4 and a second intake pipe 32 connected to the cylinder 2. The shut-off valve 5 is located between the first intake pipe 31 and the second intake pipe 32. The outer peripheral walls of the first intake pipe 31 and the second intake pipe 32 are provided with first flanges 33. The two ends of the shut-off valve 5 are provided with second flanges 51. A first sealing ring 6 is provided between the first flange 33 and the second flange 51. The first sealing ring 6 is elastic and can be made of fluororubber, which has excellent high temperature resistance and corrosion resistance. The first sealing ring 6 is fixedly connected to one of the first flange 33 and the second flange 51, or the first sealing ring 6 is provided between both of them to improve the sealing performance between the shut-off valve 5 and the intake pipe 3.

[0036] A connector 7 is provided between the first flange 33 and the second flange 51. Several connectors 7 are provided at intervals along the axis of the first flange 33. The connector 7 specifically includes a connecting bolt 71 and a connecting nut 72 threaded to the connecting bolt 71. The connecting bolt 71 passes through the first flange 33 and the second flange 51, and the connecting bolt 71 is threaded to the connecting nut 72, so as to install the first flange 33 and the second flange 51 and install the shut-off valve 5 on the air intake pipe 3.

[0037] Furthermore, a pressure sensor (not shown in the figure) is installed on the shut-off valve 5 to monitor the pressure changes in the first intake pipe 31 and the cylinder 2 in real time.

[0038] The implementation principle of the spinning ring blowing lifting device in this embodiment is as follows: When the air compressor 4 malfunctions, the shut-off valve 5 installed on the air inlet pipe 3 is used to cut off the air supply, so that the air pressure previously delivered by the air compressor 4 is stored in the cylinder 2. This allows the ring blowing tube 1 to be effectively maintained for a certain period of time, buying time for fault repair. It ensures that production is not directly interrupted during the air compressor 4 malfunction maintenance period, making it suitable for emergency scenarios. Furthermore, by incorporating the shut-off valve 5, it has the advantages of low cost and simple structure compared to existing backup air compressor 4 or large-capacity air tank solutions.

[0039] Example 2:

[0040] Reference Figure 4 , Figure 5 The difference from Embodiment 1 is that a sealing element 8 is provided between the first flange 33 and the second flange 51. In this embodiment, the sealing element 8 is elastic, and the outer diameter of the sealing element 8 is smaller than the outer diameter of the first flange 33 and the second flange 51. The sealing element 8 can be made of PTFE material or the same material as the first sealing ring 6.

[0041] In this embodiment, an insertion portion 9 protrudes from one end of the first air intake pipe 31 and the second air intake pipe 32, or from both ends of the shut-off valve 5. The diameter of the insertion portion 9 is smaller than the inner diameter of the first air intake pipe 31 and the second air intake pipe 32, or smaller than the inner diameter of the ports at both ends of the shut-off valve 5. It should be noted that the sealing element 8 can be fixed to the inner wall of the first air intake pipe 31, the second air intake pipe 32, or the shut-off valve 5, or coaxially sleeved on the outer peripheral wall of the insertion portion 9, and can be fixed to the insertion portion 9. In this embodiment, the insertion portion 9 is provided on the first air intake pipe 31 and the second air intake pipe 32, and the sealing element 8 is coaxially sleeved on the outer peripheral wall of the insertion portion 9 for demonstration.

[0042] In this embodiment, the outer peripheral wall of the sealing member 8 is inclined with a first inclined surface 81 towards the insertion part 9, and the inner peripheral walls of the first air inlet pipe 31 and the second air inlet pipe 32, or the two ends of the shut-off valve 5, are provided with a second inclined surface 10 that is slidably connected to the first inclined surface 81. In this embodiment, since the insertion part 9 is provided on the first air inlet pipe 31 and the second air inlet pipe 32, the second inclined surface 10 is provided on the inner peripheral wall of the shut-off valve.

[0043] Furthermore, a second sealing ring 82 is provided on the inner peripheral wall of the seal 8 in the middle, and an installation groove 83 is provided on the inner peripheral wall of the seal 8 for installing the second sealing ring 82, so as to further improve the sealing between the intake pipe 3 and the shut-off valve 5.

[0044] Furthermore, during installation, the sliding connection between the first inclined surface 81 and the second inclined surface 10 will exert some pressure on the seal 8. During the pressure process, relative slippage may occur. In order to reduce the possibility of relative movement of the seal 8 along the axis, in this embodiment, the first flange 33 or the second flange 51 protrudes with a limiting part 34. The seal 8 is divided into two parts according to its own diameter: the end with the larger outer diameter is the large end 84, and the end with the smaller outer diameter is the small end 85. The end face of the seal 8 located at the large end 84 is provided with a slot 86 for the limiting part 34 to slide and insert. Since the insertion part 9 is provided on the shut-off valve 5, the limiting part 34 is specifically provided on the second flange 51 for demonstration purposes.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
