Description

Technical Field

[0001] This utility model relates to the technical field of spinneret cleaning equipment, specifically an ultrasonic cleaning machine. Background Technology

[0002] The function of a spinneret is to transform a viscous polymer melt or solution into a fine stream with a specific cross-sectional shape through micropores, which then solidifies into filaments through a coagulation medium such as air or a coagulation bath. After prolonged use, residual polymer can remain on the surface of the spinneret and within the micropores, affecting the spinning effect. Regular cleaning of the spinneret is essential to ensure its proper functioning. Carbon fiber spinnerets are one type of spinneret. Patent CN207143377U describes a cleaning device for carbon fiber spinnerets that our company is currently using; as shown in the attached drawings of that patent. Figure 2 As shown, a ring of positioning through holes 3 is opened on the disc support 2, and the carbon fiber spinneret to be cleaned is placed in the positioning through holes 3. An upper ultrasonic transducer structure 5 and an ultrasonic transducer box 8 are respectively aligned with the ring positioning through holes 3 from the top and bottom directions. The ultrasonic transducer box 8 is not set directly below the upper ultrasonic transducer structure 5. However, when cleaning based on the method of this patent, the number of spinnerets to be cleaned each time is small, and multiple replacements are required to clean all the spinnerets. Summary of the Invention

[0003] To address the problem that the cleaning efficiency of existing ultrasonic cleaning equipment does not meet actual needs, this utility model provides an ultrasonic cleaning machine that can effectively increase the number of spinnerets cleaned per cycle.

[0004] The structure of this utility model is as follows: an ultrasonic cleaning machine includes a positioning device and a cleaning device. The positioning device is disposed in a cleaning tank. The positioning device includes a disc support with annularly arranged positioning through holes. The disc support is connected to a rotary drive device via a rotating shaft.

[0005] Its features are:

[0006] The positioning through holes of the same diameter form a positioning structure ring, and the number of positioning structure rings provided on the disc bracket is greater than 1;

[0007] The cleaning device includes an upper ultrasonic structure and a lower ultrasonic structure; the upper ultrasonic structure and the lower ultrasonic structure are respectively disposed above and below the disc support;

[0008] The upper ultrasonic device includes: an upper ultrasonic transducer structure, and each of the positioning structure rings is respectively provided with the corresponding upper ultrasonic transducer structure;

[0009] The lower ultrasonic device includes: a lower ultrasonic transducer and an ultrasonic transducer box. The ultrasonic transducer box has a fan-shaped structure, and the area of ​​the ultrasonic transducer box simultaneously covers all the positioning structure rings within the fan-shaped area. The total number of lower ultrasonic transducers is greater than 1, and all lower ultrasonic transducers are evenly arranged in the ultrasonic transducer box.

[0010] The ultrasonic transducer box and the upper ultrasonic transducer structure are positioned such that their vertical projections do not overlap.

[0011] Its further features are:

[0012] The rotary drive device includes: a drive motor, the output shaft of which is driven and connected to the rotating shaft based on a transmission device;

[0013] The number of ultrasonic transducers is greater than 1;

[0016] It also includes: a cabinet, wherein the positioning device and the cleaning device are both located in the inner cavity of the cabinet.

[0017] This utility model provides an ultrasonic cleaning machine in which carbon fiber spinnerets to be cleaned are placed in positioning through holes, forming a positioning structure ring. By setting multiple positioning structure rings of different diameters on a disc support, it is ensured that more carbon fiber spinnerets can be cleaned simultaneously in each cleaning cycle. The disc support is driven to rotate by a rotary drive device, and an upper ultrasonic transducer structure is set for each positioning structure ring. This ensures that the upper surface of the carbon fiber spinneret in each positioning structure ring can be cleaned by the upper ultrasonic transducer structure during rotation. At the same time, a fan-shaped ultrasonic transducer box is set below the disc support to clean the lower surface of the carbon fiber spinnerets to be cleaned on all positioning structure rings simultaneously, effectively improving the cleaning efficiency.

[0022] Figure 5 Example 2 is a disc support. Detailed Implementation

[0023] like Figures 1-5 As shown, this utility model includes an ultrasonic cleaning machine, comprising: a cleaning tank 2, a positioning device, and a cleaning device. The cleaning tank 2, positioning device, and cleaning device are all housed within the inner cavity of a cabinet 1, ensuring that liquid does not splash during the cleaning process and preventing external impurities from falling into the cleaning tank 2 and the carbon fiber spinneret to be cleaned. An exhaust port 14 is provided at the top of the cabinet 1, and a drain port 11 is provided at the bottom. The drain port is connected to the inner cavity of the cleaning tank 2 via a pipe. Simultaneously, a cleaning fluid inlet 12 is also provided on the cabinet, with one end connected to a cleaning fluid supply device (not marked in the figure) and the other end connected to the inner cavity of the cleaning tank 2.

[0024] A positioning device is installed in the cleaning tank 2. The positioning device includes a disc support 3 with annularly arranged positioning through holes 8. The disc support 3 is connected to a rotary drive device 4 via a rotating shaft 9. The rotary drive structure 4 is based on existing technology. In this embodiment, the rotary drive device 4 includes a drive motor 41. The output shaft of the drive motor 41 is driven and connected to the rotating shaft 9 via a transmission device 42. The transmission device is based on existing technology. In this embodiment, the output shaft of the drive motor 41 is fitted with a drive gear, and the outer circumference of the transmission shaft is fitted with a driven gear. The transmission gear and the drive gear are meshed and connected to form the transmission device 42. After the drive motor 41 is started, the output shaft drives the drive gear to rotate, and the drive gear drives the transmission gear and the rotating shaft 9 to rotate synchronously, thereby realizing the rotation between the discs 2.

[0025] Positioning through holes 8 of the same diameter form a positioning structure ring, and the number of positioning structure rings on the disc support 3 is greater than one. The specific number of positioning structure rings, and the number of positioning through holes 8 on each positioning structure ring, are set according to the size of the carbon fiber spinneret to be cleaned. In this embodiment, the inner cavity size of the cleaning tank 2 is 1200mm*1200mm. If a spinneret with a diameter of 150mm is placed in the corresponding disc support 3, two positioning structure rings can be set at the same time, for a total of 24 spinnerets to be cleaned. Figure 4 As shown. If a spinneret with a diameter of 192mm is used, two positioning structure rings can be set up simultaneously for 18 spinnerets to be cleaned, such as... Figure 5 As shown. If the spinneret diameter is smaller, three positioning structure rings can be set to place more spinnerets to be cleaned at once. This application can set different positioning structure rings for spinnerets of different sizes.

[0026] The cleaning device includes an upper ultrasonic structure and a lower ultrasonic structure. The upper and lower ultrasonic structures are respectively positioned above and below the disc support 3, ensuring simultaneous cleaning of the spinneret in both the upper and lower directions. In this application, the ultrasonic transducer 7 in the lower ultrasonic structure is implemented using a distributed ultrasonic device; the upper ultrasonic transducer structure 5 in the upper ultrasonic structure is implemented using a focused ultrasonic device, with each upper ultrasonic transducer structure 5 equipped with a corresponding ultrasonic transducer 6. By using the distributed ultrasonic device and the focused ultrasonic device in combination, an effective cleaning effect is achieved at a lower cost, striking a balance between cost and cleaning performance.

[0027] The upper ultrasonic device includes: an upper ultrasonic transducer structure 5, with each positioning structure ring having a corresponding upper ultrasonic transducer structure 5; the upper ultrasonic transducer structure 5 is connected to a transducer 6, and the transducer 6 is installed in the inner cavity of the cabinet 1 via an upper bracket 61. The number of upper ultrasonic transducer structures 5 corresponds one-to-one with the number of positioning structure rings. Specifically, for each upper ultrasonic transducer structure 5, the horizontal projection position on the disc bracket 3 and the vertical position of the upper ultrasonic transducer structure 5 can be adjusted via the upper bracket 61, thereby adjusting the positioning structure ring aligned with the upper ultrasonic transducer structure 5. In this embodiment, the water immersion depth of each upper ultrasonic transducer structure 5 is 10-15mm, and the working gap between the transducer and the spinneret to be cleaned is 2-4mm.

[0028] Figure 2 In this embodiment, the disc support 3, centered on the rotating shaft 9, has only two positioning structure rings formed by positioning through holes 8, and therefore only two upper ultrasonic transducer structures 5 are provided, each corresponding to one positioning ring structure. This ensures that during the rotation of the disc support 3, the spinnerets to be cleaned placed in the positioning through holes 8 on each positioning ring structure can be cleaned by the upper ultrasonic transducer structure 5 above.

[0029] The lower ultrasonic device includes: a lower ultrasonic transducer 71 and an ultrasonic transducer 7. The ultrasonic transducer 7 has a fan-shaped structure, and the area of ​​the ultrasonic transducer 7 covers all the positioning structure rings within the fan-shaped area. The total number of lower ultrasonic transducers 71 is greater than 1, and all the lower ultrasonic transducers 71 are evenly arranged in the ultrasonic transducer 7.

[0030] In practice, the number of ultrasonic transducers 7 is greater than 1; all ultrasonic transducers 7 are arranged continuously to form a sector with a central angle greater than 180 degrees; this ensures that the area under all the spinnerets to be cleaned can be covered at the same time, and that the area under the spinnerets is repeatedly rinsed by the sector-shaped ultrasonic transducers 7 with a central angle greater than 180 degrees during the rotation of the disc support 3, thereby improving rinsing efficiency.

[0031] The upper ultrasonic transducer structure 5 and the lower ultrasonic transducer 71 are respectively connected to the ultrasonic generator (not marked in the figure). For example... Figure 3 As shown, the ultrasonic transducer 7 and the upper ultrasonic transducer structure 5 are positioned so that their vertical projections do not overlap, preventing the ultrasonic wave vibrations above and below from canceling each other out.

[0032] To improve cleaning efficiency, this application also includes a cleaning fluid heating device, which includes a coil 21. The coil 21 is installed in the cleaning tank and its shape is adapted to the inner cavity of the cleaning tank 2. The coil 21 is connected to both a steam inlet 22 and a steam outlet 23. The steam inlet 21 is connected to a high-temperature steam supply device (not marked in the figure). When it is necessary to adjust the temperature of the cleaning fluid in the cleaning tank 2, high-temperature steam is introduced from the steam outlet 22 and indirectly heated through the coil 21 to the cleaning fluid in the cleaning tank 2.

[0033] To ensure the device can operate for extended periods, a compressed air inlet 13 is provided. One end of the compressed air inlet 13 is connected to a compressed air supply device (not marked in the figure), and the other end is connected to the transducer 6. After prolonged operation, compressed air is used to cool the transducer 6. The specific connection method is based on existing technology. The specific circuit design of this application is also based on existing technology.

[0034] After using the technical solution of this utility model, all the spinnerets to be cleaned are placed in the positioning through holes 8, the drive motor 41 is started, and all the spinnerets to be cleaned are rotated at a uniform speed. The upper ultrasonic structure and the lower ultrasonic structure are started, and the spinnerets to be cleaned are cleaned from the top and the bottom respectively. Based on the technical solution of this application, the micro-holes and guide holes on the spinnerets are cleaned in one go. There is no need to flip the plate during the cleaning process, which can greatly improve the cleaning efficiency.
