Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, and more specifically to a waste heat recovery molten salt energy storage hot air device. Background Art

[0002] Molten salt is currently a widely used heat transfer and heat storage medium in medium and high temperature light and thermal energy utilization systems due to its significant advantages of large heat capacity, high stability and wide operating temperature range. Announcement No. CN219607802U proposes a waste heat recovery molten salt energy storage hot air device that usually accumulates molten salt in a storage tank. When the high-temperature molten salt liquid dissipates heat and converts into a solid state, the accumulated molten salt is prone to poor or incomplete heat dissipation, and the waste heat of the molten salt cannot be fully utilized. By arranging a molten salt storage coil rotating and coiled on the inner shell on the outside of the heating component, the molten salt can be stored in a dispersed manner, and will not accumulate when the heat is dissipated, so that the internal heat can be fully dispersed and the function of the molten salt waste heat can be fully utilized.

[0003] In the above device, molten salt is stored in a rotating coil for heat storage. However, there is a height difference in the rotating coil. After the molten salt is heated and melted into a fluid, it will flow downward and accumulate. After the heat exchange is completed, the molten salt will solidify together and accumulate at the bottom of the rotating coil, which is not convenient for subsequent heating. Utility Model Content

[0008] Technical effects and advantages of this utility model:

[0009] 1. The waste heat recovery molten salt energy storage hot air device uses excess electricity to start the electric heater for heating when electricity consumption is low. The external wind is transported to the inside of the shell for heating and then transported out for heat use. The waste heat will heat the molten salt inside the spiral copper tube, and the molten salt will store heat.

At this time, the sliding bar drives the rack downward, and the gear rotation drives the mounting plate to rotate, and then drives the spiral copper tube to rotate. When the eccentric wheel is away from the T-shaped lap plate, the elastic force of the connecting spring pushes the T-shaped connecting rod upward, and the gear is turned over by the rack, causing the spiral copper tube to rotate back and forth, and then the molten salt inside the spiral copper tube can be shaken to ensure heating. At the same time, the molten salt can be dispersed during heat dissipation to avoid accumulation.

When the T-shaped positioning block moves to the bottom of the circular block, the elastic force of the reset spring pushes the T-shaped positioning block out. At this time, the obstruction of the T-shaped positioning block can complete the installation of the filter screen. The filter screen can filter impurities in the air and prevent impurities from entering the interior of the shell. BRIEF DESCRIPTION OF THE DRAWINGS
