In order to further improve the quality of the product and reduce the environmental pollution caused by dyeing and finishing processes, many new processing techniques have been tried, such as microwave, ultrasonic wave, radio wave, infrared heating, etc., wherein ultrasonic wave has been successfully applied to the fiber dispersion treatment process.

Thus, a large amount of dispersant is relied upon to form a stable, fine particulate state during the fiber dissolution process. The existing ultrasonic dispersion equipment can not be used for completely and uniformly dispersing fibers in the fiber dispersion process, so that improvement is needed.

The present application will be described in detail with reference to the accompanying drawings 1-3, in conjunction with an embodiment.
An ultrasonic fiber dispersing instrument according to an embodiment of the invention comprises a reaction kettle 1, an ultrasonic generating device 2, a liquid storage tank 3 and a laser particle size distribution instrument 4. Specifically, the reaction kettle 1 comprises a kettle shell 11, an inner cavity 12 is formed inside the kettle shell 11, the reaction kettle 1 is provided with a feed inlet 13, a feed back port 14 and a discharge port 15 which are communicated with the inner cavity 12, and the inner cavity 12 is used for containing a fiber solution to be dispersed; the ultrasonic generating device 2 is connected with the reaction kettle 1 and is used for dispersing the fiber solution in the inner cavity 12; the liquid storage tank 3 is arranged below the reaction kettle 1, the liquid storage tank 3 is connected with the discharge port 15 through a first feeding pipe 31, the liquid storage tank 3 is connected with the feed back port 14 through a second feeding pipe 32, and a liquid extracting pump 33 is arranged on the second feeding pipe 32; the laser particle size distribution instrument 4 is arranged in the liquid storage tank 3 and is used for measuring the fiber dispersion uniformity of the liquid in the liquid storage tank 3.
In the embodiment of the present invention, referring to fig. 1, in the embodiment of the present invention, an inner cavity 12 formed inside a reaction kettle 1 is used for storing a fiber solution to be dispersed, a feed port 13 is used for inputting the fiber solution to be dispersed, after the fiber solution to be dispersed is input into the inner cavity 12 from the feed port 13, an ultrasonic wave generating device 2 is used for performing ultrasonic wave dispersion treatment on the fiber solution, and under the condition that the feed port 13 continuously inputs the fiber solution to be dispersed, the fiber solution after the dispersion treatment is discharged from a discharge port 15 into a liquid storage tank 3 for temporary storage. According to the embodiment of the invention, the laser particle size distribution instrument 4 is arranged in the liquid storage tank 3, and the uniformity and consistency of fiber dispersion can be detected by using the laser particle size distribution instrument 4, so that the next step of processing can be carried out according to the detection result of the laser particle size distribution instrument 4. When the uniformity of dispersion meets the requirement, the fiber solution is stored in the liquid storage tank 3; when the uniformity of dispersion does not meet the requirement, the liquid-extracting pump 33 can be started, and the fiber solution temporarily stored in the liquid storage tank 3 is replenished into the reaction kettle 1 again along the second feeding pipe 32 under the driving of the liquid-extracting pump 33 for ultrasonic dispersion treatment until the fiber solution is uniformly dispersed and falls into the liquid storage tank 3 again through the discharge port 15.
In summary, in the embodiment of the present invention, the laser particle size distribution instrument 4 is used to detect the uniformity of the dispersion of the fiber solution temporarily stored in the liquid storage tank 3, so as to ensure that the uniformity of the fiber dispersion meets the requirement, otherwise, the fiber solution that does not meet the requirement is discharged into the reaction kettle 1 again, and the ultrasonic wave generating device 2 is used to perform ultrasonic wave dispersion again until the uniformity of the dispersion of the fiber solution discharged into the liquid storage tank 3 meets the requirement.

As another embodiment of the present invention, a water cooling tank 5 is arranged outside the reaction kettle 1, a water inlet 51 and a water outlet 52 are arranged on the water cooling tank 5, and the water inlet 51 is used for inputting circulating water for cooling. This is because ultrasonic energy of sufficiently high energy in operation produces a "cavitation effect" in which millions of bubbles are generated, which upon detonation release large amounts of energy, which causes the acoustic medium to undergo chemical bond rupture, aqueous phase combustion or thermal decomposition within the cavitation bubbles, and promotes heterogeneous interface perturbation and phase interface renewal, thereby accelerating the mass and heat transfer processes between the interfaces, and promoting a range of physical and chemical changes. Therefore, referring to fig. 1, in the embodiment of the present invention, the water cooling tank 5 is disposed outside the reaction kettle 1, so that the heat of the reaction kettle 1 can be greatly reduced, and the overheating phenomenon of the ultrasonic wave generating device 2 during operation can be avoided.
As another ultrasonic fiber disperser according to the embodiment of the present invention, the feed inlet 13 and the feed back port 14 are disposed at the lower end of the reaction vessel 1, and the discharge port 15 is disposed at the upper end of the reaction vessel 1. Referring to the attached drawing 1, in the embodiment of the present invention, a feed port 13 and a feed back port 14 are disposed at the lower end of the reaction kettle 1, so that the fiber solution to be dispersed can be supplemented from the lower end of the reaction kettle 1, and then the fiber solution to be dispersed is discharged from a discharge port 15 at the upper end to a liquid storage tank 3 after passing through an action area of the ultrasonic wave generation device 2, and is stored, such that the flow mode from bottom to top is opposite to the deposition direction from top to bottom of the fiber, so that the fiber can be better mixed in the solution, and the uniformity of fiber dispersion can be improved.
As an ultrasonic fiber dispersion instrument according to an embodiment of the present invention, the ultrasonic generator 2 includes an ultrasonic generator 21, an ultrasonic transducer 22, an ultrasonic horn 23, and an ultrasonic tool head 24; the ultrasonic generator 21 and the ultrasonic transducer 22 are arranged on the outer side of the reaction kettle 1, the ultrasonic tool head 24 is arranged inside the kettle shell 11, one end of the ultrasonic amplitude transformer 23 is arranged on the outer side of the reaction kettle 1, and the other end of the ultrasonic amplitude transformer 23 is arranged inside the kettle shell 11; the ultrasonic generator 21 is connected with the ultrasonic transducer 22, the ultrasonic transducer 22 is connected with the ultrasonic horn 23, and the ultrasonic horn 23 is connected with the ultrasonic tool head 24. Referring to FIG. 1, in an embodiment of the present invention, an ultrasonic generating device 2 is used to disperse fibers by sound waves. Specifically, the ultrasonic generator 21 is used for generating an ultrasonic electrical signal, the ultrasonic transducer 22 is used for converting the ultrasonic electrical signal into a mechanical signal, the ultrasonic horn is used for transmitting the mechanical signal of ultrasonic waves, and the ultrasonic tool head 24 is used for generating an ultrasonic signal in the fiber solution in the inner cavity 12, so as to achieve the purpose of ultrasonically dispersing the fiber solution.
As another embodiment of the present invention, the ultrasonic tool head 24 includes a first annular body 241, a second annular body 242, and a third annular body 243, the first annular body 241, the second annular body 242, and the third annular body 243 are sequentially concentrically arranged, and the first annular body 241, the second annular body 242, and the third annular body 243 are connected to the ultrasonic horn 23 through a connecting rod 244. The ultrasonic tool head 24 of the embodiment of the present invention is an important component of the ultrasonic generator 2, and functions to transmit the vibration energy of the ultrasonic waves to the action object (i.e., the fiber solution in the present embodiment). The existing ultrasonic tool head is generally in the shape of a cylinder, a cone, a cuboid and the like, the working surface of the existing ultrasonic tool head is basically the end surface of the top end, and the working surface of the existing ultrasonic tool head is generally not large in consideration of actual installation and use, so that the radiation capability is relatively concentrated, and the following defects exist: because the radiating surface of the existing ultrasonic tool head is single, the radiation sound energy has extremely strong directivity, and when the ultrasonic tool head works, the sound intensity in the container is often extremely uneven, namely, the sound intensity facing to the radiating surface of the tool head is extremely strong, and the sound intensity facing away from the radiating surface of the tool head is very weak. While the more uniform the sound intensity, the better the dispersion of the fibers. Based on this, referring to fig. 1 and fig. 2, in the embodiment of the present invention, the ultrasonic tool head 24 includes a first circular ring body 241, a second circular ring body 242, and a third circular ring body 243, the first circular ring body 241, the second circular ring body 242, and the third circular ring body 243 are concentrically arranged in sequence, and the first circular ring body 241, the second circular ring body 242, and the third circular ring body 243 are connected to the ultrasonic horn 23 through a connecting rod 244. The embodiment of the invention can use the ultrasonic longitudinal vibration to excite the bending vibration of the first circular ring body 241, the second circular ring body 242 and the third circular ring body 243, and the annular surfaces of the first circular ring body 241, the second circular ring body 242 and the third circular ring body 243 become radiation surfaces. At the time of vibration, the outer rings of the first, second, and third annular bodies 241, 242, and 243 radiate toward the outer periphery; the inner ring surfaces of the first ring body 241, the second ring body 242 and the third ring body 243 radiate towards the inside, so that the radiation area of the ultrasonic tool head 24 is greatly increased, and the working power of ultrasonic waves is further improved
As another ultrasonic fiber disperser according to an embodiment of the present invention, the first annular body 241, the second annular body 242, and the third annular body 243 have different ultrasonic radiation frequencies. In particular, the radiation frequency range of the ultrasonic tool tip 24 of the embodiments of the present invention may be between 10-100kHz, as desired. Meanwhile, for the purpose of uniform dispersion, the materials, structures, sizes, and the like of the first annular body 241, the second annular body 242, and the third annular body 243 may be slightly different, so that the ultrasonic radiation frequencies of the first annular body 241, the second annular body 242, and the third annular body 243 are different. Finally, the dispersion of the ultrasonic wave generating devices 2 under the action of different vibration frequencies is more uniform.
As an embodiment of the present invention, the ultrasonic fiber dispersion apparatus further includes a data analysis module 6, and the data analysis module 6 is respectively connected to the liquid extraction pump 33 and the laser particle size distribution instrument 4, and is configured to receive and analyze detection data of the laser particle size distribution instrument 4, and control the liquid extraction pump 33 to be turned on or turned off. Referring to fig. 3, in the embodiment of the present invention, the data analysis module 6 may be configured to receive and analyze the detection data of the laser particle size distribution analyzer 4, and control the liquid-extracting pump 33 to be turned on or off. Specifically, when the data analysis module 6 detects that the solution in the liquid storage tank 3 is uniformly dispersed, the liquid extracting pump 33 is not started; when the data analysis module 6 detects that the solution in the liquid storage tank 3 is not uniformly dispersed, the liquid extracting pump 33 can be started, so that the solution in the liquid storage tank 3 enters the reaction kettle 1 to continue to be uniformly dispersed by ultrasonic waves until the solution in the liquid storage tank 3 is uniform, and then the operation of the liquid extracting pump 33 is stopped. Therefore, the arrangement of the data analysis module 6 can ensure that the ultrasonic fiber dispersing instrument provided by the embodiment of the invention works more automatically and intelligently, so that the uniform dispersion of the fiber solution can be more accurately ensured.
Specifically, the data analysis module 6 may select an existing upper computer to implement the functions of the present application, and should not limit the present application.
As another ultrasonic fiber disperser according to the embodiment of the present invention, the second feeding pipe 32 is provided with a first check valve 7. Referring to fig. 1, the first check valve 7 is provided to prevent the solution in the reaction kettle 1 from flowing back to the liquid storage tank 3, and to prevent the solution which is not uniformly dispersed from contaminating the dispersed solution in the liquid storage tank 3.
As an ultrasonic fiber dispersion instrument according to an embodiment of the present invention, the upper end of the reaction kettle 1 is further provided with a pressure relief pipe 8, the pressure relief pipe 8 is vertically arranged, and the lower end thereof is communicated with the inside of the kettle shell 11. Referring to fig. 1, this is because the ultrasonic generator 2 may form a high-pressure environment in the reaction vessel 1 during operation, which may affect the safety of the equipment.
