Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and in particular to a device for plugging leaks in the pump seat of a spinning box. Background Technology

[0002] The spinning melt metering pump is an essential piece of equipment in the textile production process. Installed on the pump base of the spinning housing, its normal operation ensures the stability of product quality. However, the structure of the spinning melt metering pump, which is essentially a gear pump, is prone to damage after long-term operation or encountering impurities in the melt, resulting in defective products. In such cases, the spinning melt metering pump needs to be replaced. During the replacement process, if the sizing agent at the spinning position is not sufficiently frozen or undergoes abnormal carbonization or degradation, it can cause severe leakage from the spinning housing pump base. A high sizing agent flow rate further hinders freezing, making it impossible to replace the spinning melt metering pump online, thus causing the entire spinning line to shut down. Therefore, there is an urgent need to design a leak-sealing device to seal the spinning housing pump base and prevent sizing agent flow that could prevent freezing. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a device for sealing and plugging leaks in a spinning box pump seat. This device effectively seals and plugs leaks in the spinning box pump seat, thereby ensuring that the internal slurry stops flowing, achieving freezing, and facilitating the replacement of the spinning melt metering pump.

[0004] This utility model discloses a device for plugging leaks in a spinning box pump seat, comprising a transport trolley with a collection trough, a support plate at one end of the trolley, a support platform at the end of the support plate, a vertical telescopic frame on the support platform, and a melt guide pipe on the telescopic frame. The melt guide pipe is divided into a horizontal section and vertical sections on both sides. The horizontal section of the melt guide pipe is placed horizontally on the telescopic frame, and the vertical section of the melt guide pipe at one end inside the transport trolley... The section extends into the collection tank. A guide copper pipe is installed at the end of the vertical section of the melt guide pipe at one end of the transport trolley. The outer diameter of the guide copper pipe is smaller than the outer diameter of the vertical section of the melt guide pipe. An annular step is formed at the connection between the guide copper pipe and the melt guide pipe. A sealing ring is installed at the annular step. A melt valve is installed on the melt guide pipe. A support frame is installed on the horizontal section at the connection between the vertical section and the horizontal section of the melt guide pipe at one end of the transport trolley. An electro-hydraulic device is installed on the support frame.

[0005] The telescopic frame has the following structure: four guide holes are arranged in a spaced array on the support platform, and a guide rod is installed in each guide hole. The axial direction of the guide holes and guide rods is vertical. A support seat is installed on the top of the four guide rods, and a compression spring is installed between the support seat and the support platform.

[0006] It also includes a controller mounted on a transport trolley, the controller having a built-in power supply, and multiple pressure sensors arrayed on the same circumference of the side wall of the melt guide tube at the connection between the melt guide tube and the guide copper tube. The pressure sensors extend into the interior of the melt guide tube and are electrically connected to the controller. The electro-hydraulic device is also electrically connected to the controller.

[0007] Several guide members are arranged vertically at intervals on the support plate on the outside of the transport trolley. The guide members are provided with through holes. The vertical section of the melt guide tube is inserted into the through hole and is slidably connected to the guide member.

[0008] A horizontal positioning ruler is installed on the melt guide pipe at the connection between the melt guide pipe and the guide copper pipe. The structure of the horizontal positioning ruler is as follows: it includes a first connecting part and a second connecting part. The first connecting part is rotatably connected to the melt guide pipe. A slide rail is fixed on the first connecting part. The second connecting part is slidably connected on the slide rail. A positioning nut is provided on the slide rail to limit the position of the second connecting part on the slide rail. A connecting hole is provided on the second connecting part.

[0009] The present invention provides a slurry leakage plugging device for a spinning box pump seat. When the spinning box pump seat leaks, a guide copper pipe is inserted to guide the slurry along the melt guide pipe to the collection tank. During the process, pressure is applied to seal the leak, and then the melt valve is shut off to achieve the plugging. This process eliminates the risk of slurry splashing, improves the reliability of the plugging, facilitates the freezing of the spinning box pump seat, and ensures the safe replacement of the spinning melt metering pump. It is also highly efficient. Attached Figure Description

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Example 1:

[0018] like Figures 1-6 As shown, this utility model discloses a device for plugging leaks in a spinning box pump seat, including a transport trolley 1, a collection trough 2 on the transport trolley 1, a support plate 4 at one end of the transport trolley 1, a support platform 5 at the end of the support plate 4, a vertical telescopic frame on the support platform 5, and a melt guide pipe 3 on the telescopic frame. The melt guide pipe 3 is divided into a horizontal section and vertical sections on both sides. The horizontal section of the melt guide pipe 3 is placed horizontally on the telescopic frame, and the vertical section of the melt guide pipe 3 is located at one end inside the transport trolley 1. Extending into the collection tank 2, a guide copper pipe 6 is provided at the end of the vertical section of the melt guide pipe 3 at one end of the outer side of the transport cart 1. The outer diameter of the guide copper pipe 6 is smaller than the outer diameter of the vertical section of the melt guide pipe 3. An annular step is formed at the connection between the guide copper pipe 6 and the melt guide pipe 3. A sealing ring 7 is provided at the annular step. A melt valve 9 is provided on the melt guide pipe 3. A support frame 10 is provided on the horizontal section at the connection between the vertical section and the horizontal section of the melt guide pipe 3 at one end of the outer side of the transport cart 1. An electro-hydraulic device 11 is provided on the support frame 10.

[0019] In practical use, when the spinning melt metering pump needs to be replaced, the spinning box pump base needs to be frozen to fix the internal melt and prevent leakage. However, in reality, if the leakage of the spinning box pump base is large, that is, if the internal melt flows too fast, it is impossible to freeze and fix the melt, thus making it impossible to replace the spinning melt metering pump. The existing operation is to shut down the entire production line, which seriously affects production efficiency. In the solution of this application, when the leakage of the spinning box pump base is large and it is impossible to freeze the internal melt, the transport trolley 1 can be moved to the side of the spinning box pump base. The position of the transport trolley 1 and the melt guide pipe 3 is adjusted so that the guide copper pipe 6 at the vertical end of the melt guide pipe 3 is directly above the feed port of the spinning box pump base. Since in actual spinning equipment, there is a crossbeam directly above the spinning box pump base for mounting the spinning melt metering pump. After the spinning melt metering pump is removed, a space exists between the spinning box pump base and the crossbeam. The vertical section of the melt guide pipe 3 is located within this space, and the support frame 10 on the melt guide pipe 3 is located directly below the crossbeam, with the electro-hydraulic actuator 11 above it abutting against the crossbeam. The electro-hydraulic actuator 11 is a known existing product, and its specific structure will not be described in detail. The electro-hydraulic actuator 11 is telescopic. When the guide copper pipe 6 is aligned with the feed port of the spinning box pump base, the electro-hydraulic actuator 11 can be extended, lowering the entire melt guide pipe 3 and guide copper pipe 6. The guide copper pipe 6 is then inserted into the feed port of the spinning box pump base until the sealing ring 7 seals the feed port. During this process, because the guide copper pipe 6 and the melt guide pipe 3 remain unobstructed, the melt inside the spinning box pump base can flow smoothly into the collection box, achieving pressure relief. Once the flow guide copper pipe 6 is sealed to the spinning box pump seat, and the electro-hydraulic actuator 11 maintains appropriate pressure, the melt valve 9 can be closed to seal the melt, preventing further flow of the melt inside the spinning box pump seat, thus enabling cryogenic sealing. The telescopic frame supports the melt guide pipe 3; when the melt guide pipe 3 moves downwards under the pressure of the electro-hydraulic actuator 11, the telescopic frame is compressed. The melt guide pipe 3 is made of stainless steel, specifically S304 material, with an outer diameter of 1 / 2 inch and a wall thickness conforming to the SCH160 standard. The horizontal and vertical sections of the melt guide pipe 3 are connected by stainless steel right-angle elbows; the material and wall thickness of the horizontal and vertical sections and the stainless steel right-angle elbows are identical. The flow guide copper pipe 6 has an outer diameter of 12mm and a wall thickness of 2mm.

[0020] In practical use, an aluminum silicate insulation blanket can be placed over the outside of the melt guide tube 3, and the outermost layer can be fixed with sheet metal to provide heat insulation and prevent burns during operation.

[0021] The telescopic frame has the following structure: four guide holes are arranged in a spaced array on the support platform 5, and a guide rod 12 is installed in each guide hole. The axial directions of the guide holes and guide rods 12 are vertical. A support seat 13 is installed at the top of the four guide rods 12, and a compression spring 14 is installed between the support seat 13 and the support platform 5. The guide rods 12 are slidably installed in the guide holes of the support platform 5, and the support seat 13 is installed on the guide rods 12. The compression spring 14 between the support seat 13 and the support platform 5 maintains a certain distance between them. When the melt guide pipe 3 needs to move downward under the action of the electro-hydraulic device 11, the melt guide pipe 3 overcomes the elastic force of the compression spring 14 and compresses the compression spring 14, so that the support seat 13 can move downward with the guide rods 12. The telescopic frame always supports the melt guide pipe 3 to ensure its stability.

[0022] It also includes a controller 15 mounted on the transport trolley 1. The controller 15 has a built-in power supply and multiple pressure sensors 8 arrayed on the same circumference of the side wall of the melt guide tube 3 at the connection between the melt guide tube 3 and the guide copper tube 6. The pressure sensors 8 extend into the interior of the melt guide tube 3 and are electrically connected to the controller 15. The electro-hydraulic device 11 is also electrically connected to the controller 15.

[0023] Four pressure sensors 8 can be spaced apart on the vertical section sidewall of the melt guide pipe 3 at the connection with the guide copper pipe 6. The pressure sensors 8 are used to detect the melt pressure at four locations inside the melt guide pipe 3. The pressure sensors 8 are located near the feed inlet of the spinning box pump base. The four evenly spaced pressure sensors 8 can detect the pressure at four locations in the melt guide pipe 3 and transmit the pressure signals to the controller 15. The controller can then determine the sealing condition at the connection between the guide copper pipe 6 and the spinning box pump base based on the pressure data. That is, if the pressure value of one of the pressure sensors 8 is low, it can be determined that there is a possibility of leakage at the corresponding location. The seal can be checked, or the pressure of the electro-hydraulic actuator 11 can be increased. The controller 15 can receive signals and control the corresponding components. The controller 15 has a built-in power supply to provide power to the electro-hydraulic actuator 11, pressure sensors 8, etc.

[0024] Several guide members 16 are vertically spaced on the support plate 4 outside the transport trolley 1. Each guide member 16 has a through hole, and the vertical section of the melt guide tube 3 is inserted into the through hole, with a slidable connection between the vertical section of the melt guide tube 3 and the guide member 16. To ensure that the melt guide tube 3 remains vertically upright during pressurization by the electro-hydraulic pump 11, thereby ensuring that the guide copper tube 6 can be stably inserted into the feed inlet of the spinning box pump seat, two guide members 16 are vertically positioned on the support plate 4. Each guide member 16 has a through hole, and the central axes of the two through holes coincide. The vertical section of the melt guide tube 3 is located within the through hole, and the two are slidably connected. Therefore, under the pressure of the electro-hydraulic pump 11, the melt guide tube 3 can only move vertically, resulting in higher stability.

[0025] A horizontal positioning ruler is provided on the melt guide pipe 3 at the connection between the melt guide pipe 3 and the guide copper pipe 6. The structure of the horizontal positioning ruler is as follows: it includes a first connecting part 17 and a second connecting part 18. The first connecting part 17 is rotatably connected to the melt guide pipe 3. A slide rail 19 is fixed on the first connecting part 17. The second connecting part 18 is slidably connected on the slide rail 19. A positioning nut 20 is provided on the slide rail 19 to limit the position of the second connecting part 18 on the slide rail 19. A connecting hole 21 is provided on the second connecting part 18.

[0026] A horizontal positioning ruler is installed on the melt guide pipe 3 near the guide copper pipe 6. Since the melt valve 9 needs to be closed after the guide copper pipe 6 is connected to the spinning box pump base, the internal pressure increases sharply during this process, which can easily cause the melt guide pipe 3 to shake and leak at the connection. Therefore, a horizontal positioning ruler is used to maintain its stability. The first connecting part 17 of the horizontal positioning ruler is rotatably connected to the melt guide pipe 3, and the connecting hole 21 of the second connecting part 18 is used for installation on the pump shaft of the adjacent melt metering pump. The position of the second connecting part 18 on the slide rail 19 is adjusted and locked by the positioning nut 20, thereby fixing the melt guide pipe 3 between the pump shaft of the adjacent melt metering pump and the melt guide pipe 3, making the melt guide pipe 3 more stable and safer.

[0027] After closing the melt valve 9, freeze the spinning box pump base for at least one hour. Then, slightly open the melt valve 9 and observe the changes in the four pressure sensors 8. If the pressure sensors 8 remain unchanged, it indicates that the spinning box pump base has been frozen and sealed. The melt guide tube 3 can then be removed for replacement and installation of the melt metering pump. If the melt inside the melt guide tube 3 has solidified, the external aluminum silicate insulation blanket needs to be removed, and the melt guide tube 3 needs to be calcined to remove the solid melt, thus enabling the melt guide tube 3 to be reused.
