Technical Field

[0001] This invention belongs to the field of materials research technology, specifically a carbon fiber infrared heating viscometer. Background Technology

[0002] A heating viscometer is an instrument used to measure the viscosity of liquid or molten materials at a specific temperature. Its technological background dates back to the Industrial Revolution and is crucial for understanding and controlling various industrial processes.

[0003] With the rapid development of materials science and chemical industry, the demand for high-temperature, high-precision viscosity measurement has surged, leading to the emergence of numerous heated viscometers. Most existing heated viscometers utilize heating wires or heating bands to generate heat. However, these heating elements often suffer from slow heating rates, simple heating structures, uneven heating, low temperature control accuracy, and limited heating ranges, typically only reaching around 300℃. Furthermore, they suffer from poor insulation and significant heat dissipation, resulting in significant limitations in testing and large errors in the test results. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3As shown, this utility model provides a carbon fiber infrared heating viscometer, including a heating pot support 1. The heating pot support 1 is mainly used for the carbon fiber infrared heating pot and the overall viscometer system; it can provide power for the rotation of the pot body; in addition, a temperature, speed and other control system and a display screen can be set on the heating pot support 1 to facilitate the operation of the carbon fiber infrared heating pot. A vacuum heat-insulating outer pot body 8 is placed on the top of the heating pot support 1. It is made of stainless steel, alloy and other metal materials, which can effectively ensure the shape of the pot body and avoid its deformation. The hollow structure design can effectively insulate and keep the heat, prevent the generation of waste heat, and thus save energy. In addition, the inner wall of the vacuum heat-insulating outer pot body 8 can also reflect the infrared radiation waves generated during the heating of the carbon fiber heating layer back to the interior, so as to act on the internal test sample again. The inner wall of the vacuum insulated outer pot body 8 is fixed with an insulation layer 9. The insulation layer 9 can be made of any material with heat insulation effect, such as aerogel, heat insulation cotton, mica sheets, etc. This insulation layer 9 can play a role in heat insulation and heat preservation, and can also play a role in supporting and fixing the heating layer and the temperature collection element, and play a role in insulation protection, isolating the carbon fiber heating layer from the vacuum insulated outer pot body 8. A carbon fiber infrared heating layer 11 is fixedly installed on the inner wall of the heat insulation layer 9 and placed on the outer surface of the inner liner 12 of the heating pot, and is tightly attached. Its distribution can be in various forms such as weaving and winding. In addition, during the heating process, it can not only generate heat itself, but also generate infrared radiation, thereby achieving dual heating of the sample being tested, making the heating speed faster. Multiple second temperature sensing elements 10 are provided on the outer side of the carbon fiber infrared heating layer 11, and the second temperature sensing elements 10 are distributed in a stepped manner. The purpose is to form an internal and external temperature interaction with the multiple first temperature sensing elements 7 distributed on the viscometer test head, so as to form mutual temperature feedback. When the temperature difference between the two exceeds 0.5℃, the instrument will alarm. At this time, the heating pot will quickly reduce the temperature difference between the inside and outside of the pot to the error range under the control of the required temperature. Manual intervention can also be used to balance the temperature to achieve the purpose of precise temperature control. The inner wall of the carbon fiber infrared heating layer 11 is fixed with a heating pot inner liner 12. The heating pot inner liner 12 must be made of a material that is resistant to high temperature, has high cleanliness, and can transmit infrared radiation waves, such as quartz, ceramic, sapphire, etc. It is mainly used to hold viscosity test samples.

[0016] Specifically, the top two sides of the heating pot support 1 are fixed with tester support rods 2 for raising and lowering the viscosity tester 5. The outer sides of the two tester support rods 2 are slidably provided with tester carriers 3 for supporting the viscosity tester 5. The top of the tester carrier 3 is fitted with the viscosity tester 5 on the side facing away from the tester support rods 2 for testing the viscosity of the sample.

[0017] Furthermore, the bottom of the viscosity tester 5 is rotatably equipped with a viscometer test head body 6. The lower outer side of the viscometer test head body 6 is equipped with a first temperature sampling element 7, which has a rotation function and is mainly used to test the viscosity of the sample. In addition, multiple first temperature sampling elements 7 are set at its end, which can form an internal and external temperature interaction with multiple second temperature sampling elements 10 distributed on the external carbon fiber heating layer, and provide mutual feedback to achieve the purpose of precise temperature control.

[0018] Furthermore, the outer side of the tester carrier 3 is provided with a lifting and fixing component 4 that rotates spirally, and the other end of the lifting and fixing component 4 is attached to the outer side of the tester support rod 2 to fix the position of the viscosity tester 5.

[0019] It is worth noting that the top of the vacuum insulated outer pot body 8 is fitted with a porous heating pot cover 13, and the viscometer test head body 6 penetrates the center of the porous heating pot cover 13. The top of the porous heating pot cover 13 has holes at equal intervals. The porous heating pot cover 13 is made of stainless steel, alloy or other metal materials, which can reflect the infrared radiation waves generated inside the carbon fiber heating pot and act on the test sample again; to a certain extent, it can ensure the cleanliness of the sample during the test process; the porous design can ensure the balance of internal and external atmospheric pressure during the test.

[0020] It is worth noting that handles are fixed on both sides of the top of the perforated lid 13 of the heating pot, which can be used to make it easy to pick up the perforated lid 13 of the heating pot.

[0021] Working principle: During use, the test sample is placed inside the inner pot 12 of the heating pot, and the porous lid 13 of the heating pot is placed on top of the vacuum insulated outer pot 8. The tester support rod 2 slides the tester carrier 3 on the outside of the sliding tester carrier 3, which moves up and down. The up and down movement of the tester carrier 3 drives the viscometer test head body 6 at the bottom of the viscometer 5 to move. The lower part of the viscometer test head body 6 is placed into the test sample inside the inner pot 12 of the heating pot. The heating pot support 1 provides power to the carbon fiber infrared heating layer 11, which heats the test sample inside the inner pot 12. The second temperature sampling element 10 is used to control the temperature and forms an internal and external temperature interaction with the first temperature sampling element 7, forming a temperature feedback. When the temperature difference between the two exceeds 0.5℃, the instrument will alarm. The viscometer test head body 6 has its own rotation function. During the rotation, it is used to test the viscosity of the sample and transmit the sample viscosity data to the viscometer 5, thereby achieving accurate measurement of the test sample data.
