DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, a spinning slurry spinnability test device includes a first container 2, which can be used to prepare slurry or can also be used to contain oil for testing a spinneret 6. A stirring shaft 14 is provided in the first container 2, and a plurality of stirring blades are connected to the stirring shaft 14, which can be used to stir the slurry raw material put into the first container 2 to prepare the slurry. The stirring shaft 14 is driven by a driving motor 1 arranged outside the first container 2. Specifically, the top of the stirring shaft 14 is connected to the output shaft of the driving motor 1, for example, the output shaft of the driving motor 1 is connected to the stirring shaft 14 through a belt mechanism or a gear mechanism.

[0019] The outside of the first container 2 is coated with an electric heating layer 13. When preparing the slurry, the electric heating layer 13 can be activated to heat the first container 2 to provide necessary temperature conditions for the preparation of the slurry.

[0020] Specifically, an electric heating wire is embedded in the electric heating layer 13 , and the electric heating wire generates heat after being energized to heat the slurry in the first container 2 .

[0021] Furthermore, a thermometer 3 is also provided on the first container 2, which can realize real-time measurement of the temperature of the slurry in the first container 2. The technician can immediately see the temperature of the slurry to ensure the quality of slurry preparation and the consistency of different batches of slurry.

[0022] In order to ensure that the first container 2 has sufficient volume, the volume of the first container 2 is not less than 5L.

[0023] The spinning slurry spinnability testing device also includes a second container 8 and a delivery pipe, the front end of the delivery pipe is connected to the discharge port of the first container 2, and the rear end of the delivery pipe is fixedly connected to a spinneret 6, and the nozzle of the spinneret 6 faces the second container 8, that is, the liquid in the first container 2 can flow to the second container 8 through the delivery pipe.

[0024] The delivery pipe is provided with a first delivery pump 4, which is used to pump the slurry in the first container 2 to the spinneret 6, and smoothly deliver the slurry in the spinneret 6 to the second container 8. The first delivery pump 4 is driven by a first motor 10, and the delivery pressure in the delivery pipe can be controlled by controlling the rotation speed of the second motor 12, so as to achieve the regulation and control of the spinning speed.

[0025] The second container 8 can be placed on a workbench 7 or other supporting structures with a flat surface.

[0026] Furthermore, the delivery pipe is also provided with a pressure sensor 5, which can be used to monitor the pressure in the delivery pipe, ensure the stability of the pressure in the delivery pipe, avoid the pressure change in the delivery pipe affecting the slurry spinning quality, and effectively reduce the safety risks caused by excessive pressure in the delivery pipe. The pressure sensor 5 can also help technicians to promptly detect abnormal pressure in the delivery pipe, and can achieve real-time monitoring of related equipment.

[0027] The working process of spinning using the spinning slurry spinnability testing device disclosed in the utility model is as follows:

[0028] First, various raw materials for preparing spinning slurry are put into the first container 2, and the electric heating layer 13 outside the first container 2 is started to heat the raw materials. When the temperature in the first container 2 reaches the temperature required for slurry preparation, the stirring paddle is started to stir the slurry raw materials in the first container 2 so that the slurry raw materials are fully mixed to obtain spinning slurry. Subsequently, these prepared spinning slurries will be transported to the spinneret 6 through the delivery pipe, and the slurry will be sprayed from the spinneret 6 to form fibers in the second container 8. Collect the fibers formed in the second container 8. The spinnability of the slurry can be judged by observing the curling degree, cohesion and other performances of the fiber or by pulling the fiber to detect the strength and elongation properties of the fiber.

[0029] Therefore, the spinning slurry spinnability testing device disclosed in the utility model can be used to test the spinnability of slurries of different specifications and types with different components and different ingredient ratios, which is convenient for technicians to quickly determine the spinnability of slurries with new components or new ratios, thereby improving the efficiency of slurry preparation verification.

[0030] The spinning slurry spinnability testing device disclosed in the utility model can be used to detect the performance of the spinneret 6. When testing the performance of the spinneret 6, firstly, oil of a specific viscosity is put into the first container 2, and then, driven by the delivery pump, the oil output from the first container 2 flows through the delivery pipe, the spinneret 6 and finally into the second container 8. When the spinneret 6 sprays the oil, the form of the oil spraying can be observed and detected, and the performance of different spinnerets 6 can be tested.

[0031] Furthermore, the discharge port of the second container 8 is also connected to a reflux pipe, the end of which is connected to the first container 2, and the oil flowing out of the discharge port of the second container 8 can flow back to the first container 2 through the reflux pipe. In other words, the oil can circulate in the first container 2 and the second container 8, so that multiple different spinnerets 6 can be tested without changing the oil, and of course, the same spinneret 6 can also be tested multiple times. The reuse of the oil can greatly reduce the loss of the oil and effectively reduce the cost of experimental testing.

[0032] The reflux pipe is connected with a second delivery pump 9 to drive the oil or other liquid in the second container 8 to flow back into the first container 2. The second delivery pump 9 is driven by a second motor 12.

[0033] Preferably, the second motor 12 is a variable frequency motor.

[0034] Furthermore, the spinning slurry spinnability test device also includes an electric control system, which includes a programmable logic controller (PLC). The programmable logic controller is connected to the electric heating layer 13, the first motor 10, the second motor 12, the thermometer 3, the pressure sensor 5 and other devices in communication, and the first motor 10 and the second motor 12 can be controlled by the programmable logic controller to control the working state of the first delivery pump 4 and the second delivery pump 9, and the electric heating layer 13 can also be controlled according to the slurry preparation requirements of the first container 2 to more accurately control the temperature in the first container 2. The monitoring data of the pressure sensor 5 and the thermometer 3 can also be transmitted to the programmable logic controller, and the programmable logic controller transmits the real-time measurement results of the pressure sensor 5 and the thermometer 3 to the server for storage, and at the same time sends them to a terminal device that is convenient for technicians to view, such as a handheld mobile terminal.

[0035] Furthermore, the programmable logic controller is installed in the electric control cabinet 11 to improve the safety of the electric control system and reduce external interference.

[0036] The electric control cabinet 11 is provided with an operation panel including a touch screen and physical buttons. The programmable logic controller is connected to the operation panel, and the input and modification of control instructions to the programmable logic controller can be completed through the operation panel. The technician can also know the operating status of the spinnability testing device through the equipment information and equipment parameters displayed on the touch screen.

[0037] It should be noted that the communication connection can be achieved through a signal transmission cable connection, such as through an optical fiber connection, or it can be achieved through a wireless communication module to achieve a wireless communication connection, such as using 4G / 5G, Zigbee, WiFi and other wireless communication protocols to achieve wireless communication interaction.
