Technical Field

[0001] The utility model relates to the technical field of cleaning molten salt heat exchangers, in particular to an easy-to-clean molten salt heat exchanger. Background Art

[0002] The molten salt heat exchanger is a heat exchange device widely used in industry. It uses molten salt as the working fluid and transfers and exchanges heat through conduction, convection and radiation. Molten salt is usually composed of mixed salts such as sodium chloride and potassium chloride. Molten salt exhibits good fluidity and low viscosity at high temperatures, while the fluidity of molten salt decreases or completely loses at low temperatures, and the viscosity increases significantly. This results in some molten salt and other impurities remaining in the finned tubes of the heat exchanger after heat exchange. When cleaning the finned tubes of the existing molten salt heat exchanger, it is necessary to disassemble the equipment and perform high-pressure water or air flushing on the inner tube wall of the finned tube one by one to complete the cleaning, which is very inconvenient, and the cleaning effect is general, which is not conducive to improving the performance and service life of the molten salt heat exchanger. Utility Model Content

The utility model provides an easy-to-clean molten salt heat exchanger, which can clean the entire fin tube, has a simple cleaning process and good cleaning effect, which is beneficial to improving the performance and service life of the molten salt heat exchanger.

[0004] The utility model provides the following technical solutions:

[0005] It includes a molten salt heat exchanger body, and the finned tubes inside the molten salt heat exchanger body are installed in a row and vertically. It is characterized in that a rotatable collecting main board is installed at the head of the molten salt heat exchanger body, and a fixed support plate is arranged between the collecting main board and the finned tubes, and the fixed support plate is clamped on the head of the molten salt heat exchanger body.

[0006] It is further characterized by:

[0007] A support seat is installed on the left side of the molten salt heat exchanger body, the width of the side of the support seat gradually decreases from right to left and stress grooves are opened on the side, and above the stress grooves, mainboard rotating columns are symmetrically installed on the surface of the support seat, and the head of the mainboard rotating column extends into the groove at the tail of the current collecting mainboard and is rotatably connected to the current collecting mainboard;

[0008] A support pad is installed on the surface of the support seat, the tail end of the support pad is close to the mainboard rotating column and the plate body gradually extends to the left evenly until the end of the protruding end is flush with the end of the free end of the support seat, and the support pad plays a stable supporting role for the current collecting mainboard after rotation and expansion;

[0009] A vibration motor is installed at the middle part of the bottom surface of the molten salt heat exchanger body.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The molten salt heat exchanger body is provided with a rotatable current collecting main board, which can directly connect the fixed support plate to the air pressure device after opening. The fixed support plate ensures the overall stability of the finned tube, so that it can withstand the scouring of high-pressure airflow. The cleaning steps are simple, time-saving and labor-saving, which is conducive to improving the performance and service life of the molten salt heat exchanger.

[0012] A vibration motor is installed at the bottom of the molten salt heat exchanger body. The raised bottom plate ensures the stability of the entire equipment when the vibration motor is working.
