A molten salt furnace that is easy to maintain, characterized in that the molten salt furnace comprises: a molten salt furnace body 1 and a molten salt furnace cover 2 covering the open part of the molten salt furnace body 1; wherein the molten salt furnace cover 2 comprises: a plurality of temperature measuring devices 5, a radar level gauge 6, a pressure relief valve 7 and an acoustic and visual alarm component 8 connected to the upper surface of the molten salt furnace cover 2 through a flange, the measuring ends of the plurality of temperature measuring devices 5 respectively penetrate the upper surface of the molten salt furnace cover 2 and extend into the interior of the molten salt furnace body 1, and their measuring ends are respectively located at different heights and positions inside the molten salt furnace, the measuring end of the radar level gauge 6 is located inside the molten salt furnace cover 2 to measure the liquid level height, the pressure relief valve 7 is arranged on the upper surface of the molten salt furnace cover 2 for automatically relieving pressure when the internal pressure is too high, and the acoustic and visual alarm component 8 is respectively electrically connected to the radar level gauge 6 and the plurality of temperature measuring devices 5 to issue an alarm when their values ​​deviate from the set values.

[0031] The present application detects the temperature at different heights and positions in the molten salt furnace in real time through a temperature measuring device 5 with multiple measuring ends located at different heights and positions inside the molten salt furnace, which helps to detect temperature anomalies in time and improves the safety and stability of the molten salt furnace. The setting of the radar level gauge 6 can accurately measure the liquid level height in the molten salt furnace to ensure that the use and storage of the molten salt in the molten salt furnace are in good condition. The setting of the pressure relief valve 7 can automatically release pressure when the internal pressure of the molten salt furnace is too high, avoiding the potential safety hazards caused by the excessive pressure inside the furnace body. The sound and light alarm component 8 is electrically connected to the radar level gauge 6 and the temperature measuring device 5, and can sound an alarm when the liquid level or temperature deviates from the set value, reminding the operator to take corresponding measures, thereby ensuring the safe operation of the molten salt furnace.

[0035] The molten salt furnace of this design in the present application has an audible and visual alarm system. When the value of the radar level meter 6 or the temperature measuring device 5 deviates from the set value, the buzzer 801 will sound an alarm and the alarm light 802 will flash to remind the operator to take corresponding measures. Such a design helps to detect temperature or liquid level abnormalities in a timely manner and ensure the safe operation of the molten salt furnace.

[0036] Reference Figure 1 The upper surface of the molten salt furnace cover plate 2 is also flange-connected with a plurality of pumps 9 for extracting the molten salt liquid inside for use and a salt return pipeline 10 for recovering the molten salt liquid whose temperature has been reduced after use.

[0045] This design of the present application allows the operator to conveniently use the handle 13 to remove the molten salt furnace cover 2 when inspection or maintenance is required, thereby improving the convenience and safety of operation.

[0046] Reference Figure 2 and Figure 6 The bottom side of the molten salt furnace body 1 is surrounded by a plurality of electric heating rods 3 inserted therein for heating the molten salt liquid, and the rod bodies of each electric heating rod 3 are arranged in a staggered manner.

[0047] The design of the present application enables the electric heating rods 3 to be evenly distributed at the bottom of the molten salt furnace, effectively heating the molten salt liquid and improving the heating efficiency.
