Description

Technical Field

[0001] This utility model belongs to the field of hair fiber production technology, specifically relating to a monitoring device for the blockage of cooling water jackets in hair fibers. Background Technology

[0002] The production of synthetic fibers involves a cooling system during the spinning process. This system is designed to dissipate excess heat generated by the shearing and frictional heating of the screw extruder during operation, preventing issues such as decreased melt viscosity or plastic decomposition due to temperature rise. The screw extruder is externally equipped with a cooling water jacket. Cooling water is transported from the cooling tower to the cooling water jacket via cold water pipes, and the heated water returns to the cooling tower via hot water pipes. Over time, various blockages can occur within the cooling water jacket, affecting the cooling effect on the screw extruder and consequently impacting spinning quality. Currently, it's difficult to visually determine the cleaning cycle for the cooling water jacket by observing blockages. Therefore, the protective sleeve is removed periodically to check for blockages and clean the interior. This method is rather reactive; sometimes, disassembly reveals no blockages, thus impacting work efficiency. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a monitoring device for the blockage of fiber cooling water jackets that is installed on pipelines, easy to operate, and provides real-time and intuitive monitoring.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device for monitoring the blockage of a fiber cooling water jacket, comprising an inlet pipe connector, a transparent conical tube, a cover plate, and an outlet pipe connector arranged sequentially from top to bottom. The transparent conical tube is smaller at the top and larger at the bottom. The upper end of the transparent conical tube is connected to the lower end of the inlet pipe connector. The cover plate is detachably connected to the lower port of the transparent conical tube. The upper end of the outlet pipe connector is connected to the center of the cover plate. An elastic valve assembly located inside the transparent conical tube is provided on the upper surface of the cover plate. A scale line for monitoring the position of the elastic valve assembly is opened on the outside of the transparent conical tube along the generatrix direction.

[0005] The resilient valve assembly includes a disc-shaped valve plate, which is aligned with and parallel to the cover plate. The bottom surface of the valve plate and the top surface of the cover plate are connected by several compression springs, which are arranged in a circumferential array along the center line of the cover plate. The bottom surface of the valve plate is provided with an upper positioning post located inside the upper end of the compression spring, and the top surface of the bottom plate is provided with a lower positioning post located inside the lower end of the compression spring.

[0006] The lower outer edge of the transparent conical tube is integrally provided with an annular plate. The top surface of the cover plate and the bottom surface of the annular plate are attached to each other and connected as one unit by several bolt assemblies arranged in a circular array. A sealing ring is provided between the top surface of the cover plate and the bottom surface of the annular plate.

[0007] Several tension members are provided between the top surface of the cover plate and the inner wall of the transparent conical tube. All tension members are arranged in a circumferential array along the center line of the cover plate and are located outside the elastic valve assembly.

[0008] Each tensioning component includes a first L-shaped plate and a second L-shaped plate. The lower end of the vertical section of the first L-shaped plate is fixedly connected to the top surface of the cover plate, and the upper end of the vertical section of the second L-shaped plate is fixedly connected to the inner wall of the transparent conical tube. A hook gap is formed between the upper horizontal section of the first L-shaped plate and the cover plate. The lower horizontal section of the second L-shaped plate extends into the hook gap. The bottom surface of the upper horizontal section of the first L-shaped plate and the top surface of the lower horizontal section of the second L-shaped plate are pressed together.

[0009] Both the outer circle of the cover plate and the outer circle of the annular plate are provided with corresponding upper and lower installation positioning mark grooves.

[0010] Compared with the prior art, the present invention has the following advantages by adopting the above technical solution: 1) This utility model is installed on the cold water pipe supplying water to the adjacent cooling water jacket, and the smoothness of water flow is observed in real time according to the scale corresponding to the position of the valve plate. A transparent conical tube is provided to facilitate observation of the position of the valve plate on the scale line to determine whether there is a blockage in the pipe.

[0011] 2) The cover plate is fixedly connected to the annular plate by several bolt assemblies, which facilitates the installation of the internal elastic valve assembly, and a sealing ring is provided to ensure the reliability of the seal.

[0012] 3) Due to the large area of ​​the cover plate and the small diameter of the outlet pipe joint, a tensioning component is specially designed to prevent the cover plate from bulging downwards in the middle due to high water pressure and thus affecting the sealing performance. When the cover plate is under pressure, the second L-shaped plate pulls on the first L-shaped plate, thereby keeping the cover plate level and ensuring the seal between the cover plate and the annular plate, while also improving the strength of the cover plate.

[0013] 4) When installing the cover plate, first make the installation positioning mark groove on the cover plate offset from the installation positioning mark groove on the ring plate by a certain angle. Then rotate the cover plate or transparent conical tube to make the installation positioning mark grooves on the cover plate and the ring plate correspond. The holes of the corresponding through bolt assemblies between the cover plate and the ring plate are all connected one by one. At this time, the horizontal section of the lower end of the second L-shaped plate extends into the hook gap to ensure that each tensioning component is assembled and connected in place.

[0014] In summary, this utility model has a scientific principle, simple structure, and is installed on a pipeline using a mechanical structure, making it less prone to damage and with a long service life. By observing the scale value corresponding to the position of the valve plate, it is possible to determine whether the annular water jacket outside the screw extruder is blocked or severely blocked. The blockage situation inside the sleeve is analyzed to determine whether maintenance and unblocking are required, thus allowing for timely disassembly of the annular water jacket.

Detailed Implementation

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a fiber cooling water jacket blockage monitoring device, comprising an inlet pipe connector 1, a transparent conical tube 2, a cover plate 3, and an outlet pipe connector 4 arranged sequentially from top to bottom. The transparent conical tube 2 is smaller at the top and larger at the bottom. The upper end of the transparent conical tube 2 is connected to the lower end of the inlet pipe connector 1. The cover plate 3 is detachably connected to the lower port of the transparent conical tube 2. The upper end of the outlet pipe connector 4 is connected to the center of the cover plate 3. The upper surface of the cover plate 3 is provided with an elastic valve assembly located inside the transparent conical tube 2. The outside of the transparent conical tube 2 is provided with a scale line 5 along the generatrix direction for monitoring the position of the elastic valve assembly.

[0018] The elastic valve assembly includes a disc-shaped valve plate 6, which is co-centered and parallel to the cover plate 3. The bottom surface of the valve plate 6 and the top surface of the cover plate 3 are connected by a number of compression springs 7. The number of springs are arranged in a circumferential array along the center line of the cover plate 3. The bottom surface of the valve plate 6 is provided with an upper positioning post 8 located inside the upper end of the compression spring 7, and the top surface of the bottom plate is provided with a lower positioning post 9 located inside the lower end of the compression spring 7.

[0019] The lower outer edge of the transparent conical tube 2 is integrally provided with an annular plate 10. The top surface of the cover plate 3 is attached to the bottom surface of the annular plate 10 and connected as a whole by a number of bolt assemblies 11 arranged in a circular array. A sealing ring 12 is provided between the top surface of the cover plate 3 and the bottom surface of the annular plate 10.

[0020] Several tension members are provided between the top surface of the cover plate 3 and the inner wall of the transparent conical tube 2. All tension members are arranged in a circumferential array along the center line of the cover plate 3 and are located outside the elastic valve assembly.

[0021] Each tensioning member includes a first L-shaped plate 13 and a second L-shaped plate 14. The lower end of the vertical section of the first L-shaped plate 13 is fixedly connected to the top surface of the cover plate 3, and the upper end of the vertical section of the second L-shaped plate 14 is fixedly connected to the inner wall of the transparent conical tube 2. A hook gap is formed between the horizontal section of the upper end of the first L-shaped plate 13 and the cover plate 3. The horizontal section of the lower end of the second L-shaped plate 14 extends into the hook gap. The bottom surface of the horizontal section of the upper end of the first L-shaped plate 13 is pressed into the top surface of the horizontal section of the lower end of the second L-shaped plate 14.

[0022] Both the outer circle of the cover plate 3 and the outer circle of the annular plate 10 are provided with corresponding upper and lower installation positioning mark grooves 15.

[0023] The working process of this utility model is as follows: First, connect the inlet pipe connector 1 and the outlet pipe connector 4 to the cold water pipe that supplies water to the external cooling water jacket of the screw extruder. High-pressure water enters the transparent conical tube through the inlet pipe connector 1, applying pressure to the valve plate 6. The valve plate 6 moves downward, and the compression spring 7 is compressed. The high-pressure water flows downward through the annular gap between the outer circle of the valve plate 6 and the inner wall of the transparent conical tube, and then is discharged through the outlet pipe connector 4. Since a scale line 5 for monitoring the position of the valve plate 6 is opened on the outer wall of the transparent conical tube 2, the position of the valve plate 6 is 0 when the outer circle of the valve plate 6 contacts the inner circle of the transparent conical tube. The scale line 5 is marked with numbers sequentially from 0 down. The scale value corresponding to the position of the valve plate 6 is set to the range of 8-20 as the normal water pressure scale. When the scale value corresponding to the valve plate 6 is in the range of 0-8, it indicates that a blockage has occurred in the cooling water jacket. The smaller the scale value, the more serious the blockage. At this time, it is necessary to stop the spinning operation and disassemble the cooling water jacket to clear the blockage.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
