Problems solved by technology
Because the molten salt is a mixture, there is no fixed melting point, which makes the determination of the melting point of the molten salt particularly difficult.
At present, the commonly used equipment for measuring molten salt is to use differential thermal analysis, which measures the melting point of molten salt according to the law of heat and temperature changes. This method requires high equipment accuracy and measurement technology, so the equipment is expensive and expensive. Unable to be widely used

Embodiment Construction
[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] This embodiment relates to an imaging method for measuring the melting point of molten salt, wherein the "imaging method" implies that the main design idea of the measuring device is to record the deformation image of the molten salt sample as the temperature changes, and The deformation image is compared with the temperature to determine the melting point of the molten salt. Such as figure 1 As shown in , the device for determining the melting point of molten salt by image method mainly includes a high-temperature furnace 1, a temperature sensor 8, a high-temperature furnace controller 10, a camera device, an image acquisition card 12, a variable light source and a lighting co...

Abstract
The invention relates to an image-method-based method for measuring a melting point of molten salt. The device comprises a high temperature furnace, a temperature sensor, a high temperature furnace controller, a camera device, an image acquisition card, a variable light source, a light control unit and a computer. The computer is connected with the the high temperature furnace controller and the image acquisition card electrically. The computer is configured to send a start-stop signal to the high-temperature furnace controller due to external triggering, so that the high-temperature furnace controller controls the high-temperature furnace to start or stop; a temperature signal can be carried and the high temperature furnace controller is controlled based on the temperature signal to control the temperature rising speed of the high temperature furnace; and the computer can carry out comparison and analysis on the temperature signal and the image signal to obtain the melting point of amolten salt sample. According to the invention, with the provided device, the computer can carry out comparison and analysis on the temperature signal and the image signal to obtain the melting pointof the molten salt sample; and the measuring process is simple. The accuracy requirement of the measuring device is low; and the device has a simple structure with low cost.
Description
technical field [0001] The invention relates to the technical field of melting point measuring equipment, in particular to a device for measuring the melting point of molten salt by image method. Background technique [0002] As one of the mainstream high-temperature heat storage materials in the world, molten salt has strict requirements on the use temperature, so it is very important to determine the melting point of molten salt. Because molten salt is a mixture, there is no fixed melting point, which makes the determination of the melting point of molten salt particularly difficult. At present, the commonly used equipment for measuring molten salt is to use differential thermal analysis, which measures the melting point of molten salt according to the law of heat and temperature changes. This method requires high equipment accuracy and measurement technology, so the equipment is expensive and expensive. Can not be widely used. Therefore, there is an urgent need to propo...
