Description

Technical Field

[0001] The utility model relates to the technical field of material temperature measurement, in particular to a temperature measurement structure for high-viscosity materials. Background Art

[0002] With the rapid development of the medical aesthetics industry, the demand for the treatment of high-viscosity materials such as gels is increasing day by day. During the gel mixing and sterilization processes, accurately measuring the material temperature is the key to ensuring product quality and process safety.

[0003] Since the gel is a high-viscosity material, the heat transfer between its materials is not good. Therefore, generally two temperature sensors need to be arranged, namely the upper material temperature detection and the bottom material temperature detection; and currently, the bottom temperature sensor usually welds the probe rod of the temperature probe to the bottom of the tank. Since the probe rod is a protruding structure, it will affect the circumferential rotation of the spiral ribbon. Therefore, usually if the temperature probe rod is welded to the bottom of the tank, a corner of the spiral ribbon needs to be cut off, but this will seriously affect the mixing efficiency of the bottom material and the discharging at the bottom. Summary of the Utility Model

[0004] Aiming at the problems of inaccurate temperature measurement, affecting the mixing efficiency and emptying, etc. existing in the temperature measurement of high-viscosity materials in the prior art, the utility model proposes a temperature measurement structure, aiming to improve the temperature measurement accuracy and avoid affecting the material mixing and emptying at the same time.

[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the accompanying drawings in the present invention.

[0018] Embodiment 1, as Figure 1-2 shown, a temperature measuring structure for high-viscosity materials includes a hollow stirring shaft 1, the hollow stirring shaft 1 is installed inside a reaction chamber 2, a gearbox 3 is installed above the reaction chamber 2, a driving motor 4 is installed on the side of the gearbox 3, the upper end of the hollow stirring shaft 1 sequentially passes through the reaction chamber 2 and the gearbox 3, and the hollow stirring shaft 1 and the output shaft of the driving motor 4 are connected by a gear pair transmission inside the gearbox 3;

[0019] A slip ring seat 5 is fixedly installed above the gearbox 3. A conductive slip ring 6 is installed inside the slip ring seat 5. The inner ring of the conductive slip ring 6 is fixedly connected coaxially with the hollow stirring shaft 1. The conductive slip ring 6 is connected to one end of a transmission cable 7. The other end of the transmission cable 7 passes through the hollow cavity of the hollow stirring shaft 1 and is connected to a first temperature sensor 8. The first temperature sensor 8 is fixedly installed at the lower end of the hollow stirring shaft 1. An eccentric position on the upper surface of the reaction chamber 2 is fixedly installed with a second temperature sensor 9. The probe end of the second temperature sensor 9 is located inside the cavity of the reaction chamber 2.

[0020] Working principle:

[0021] During use, the hollow stirring shaft 1 rotates under the driving action of the driving motor 4 to stir the high-viscosity material in the reaction chamber 2. In this utility model, by installing the slip ring seat 5 above the gearbox 3, the static ring of the conductive slip ring 6 is installed on the slip ring seat, and the moving ring of the conductive slip ring 6 is fixedly connected coaxially with the hollow stirring shaft 1 to rotate synchronously with the hollow stirring shaft 1. Since the first temperature sensor 8 is fixed at the lower end of the hollow stirring shaft 1, the first temperature sensor 8 will rotate together with the hollow stirring shaft 1. Therefore, through the conductive slip ring 6, it can be ensured that the first temperature sensor 8 can rotate synchronously without causing the problem of the transmission cable 7 being wound and broken, thus ensuring data transmission. At the same time, since the first temperature sensor 8 is located at the lower end of the hollow stirring shaft 1, it can meet the measurement of the lowest point of the material without affecting the normal use of the hollow stirring shaft 1, so as to ensure the accuracy of the measurement. At the same time, since the stirring shaft does not need to cut the spiral ribbon due to the installation of the temperature probe, the integrity of the spiral ribbon is ensured, thereby improving the mixing efficiency of the material. And it also makes the material emptying smoother without residue.

[0022] Embodiment 2, as a further preferred solution of Embodiment 1, a sealing gasket is fixedly installed between the first temperature sensor 8 and the lower end face of the hollow stirring shaft 1. Through the sealing gasket, the sealing effect between the first temperature sensor 8 and the lower end face of the hollow stirring shaft 1 can be effectively ensured, thereby effectively preventing the material from entering the hollow cavity of the hollow stirring shaft 1.

[0023] Embodiment 3, as a further preferred solution of Embodiment 1, a sealing slip sleeve 12 is fixedly installed on the upper surface of the reaction chamber 2. The hollow stirring shaft 1 passes through the sealing slip sleeve 12 and is slidably connected to the sealing slip sleeve 12. Through the sealing slip sleeve 12, the sealing performance when the hollow stirring shaft 1 slides relative to the reaction chamber 2 can be ensured.

[0024] Embodiment 4, as a further preferred solution of Embodiment 1, an opening 10 is provided at an eccentric position on the upper surface of the reaction chamber 2. A cover 11 is movably connected to the opening 10 through a hinge. The second temperature sensor 9 passes through the cover 11 and is hermetically connected to the cover 11. By means of the second temperature sensor 9, the temperature of the upper-layer material in the reaction chamber 2 can be detected.
