[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-4 A molten salt energy storage and heat exchange device that is easy to inject includes a heat exchange box 1, a storage barrel 101 is fixedly connected to the top of the heat exchange box 1, a feeding assembly 2 is installed on the inner wall of the storage barrel 101, and the feeding assembly 2 is used to inject the molten salt in the inner cavity of the storage barrel 101 into the inner cavity of the heat exchange box 1. A discharge assembly 3 is installed at the bottom of the heat exchange box 1, and the discharge assembly 3 is used to discharge the molten salt in the inner cavity of the heat exchange box 1. It also includes:

[0023] The feeding assembly 2 includes a mounting plate 201, which is fixedly mounted on the top of the material storage barrel 101. A first servo motor 202 is fixedly connected to the top of the mounting plate 201. A first rotating shaft 203 is fixedly connected to the output end of the first servo motor 202, and the first rotating shaft 203 extends to the inner cavity of the material storage barrel 101. Collision plates 204 are slidably connected to the top of the material storage barrel 101 on both sides of the first servo motor 202. A connecting column 205 is fixedly connected to the bottom of the collision plate 204, and the connecting column 205 extends to the inner cavity of the material storage barrel 101.

[0024] A concave plate 206 is fixedly connected to the side wall of the inner cavity connecting column 205 located in the storage barrel 101, a spring 207 is fixedly connected between the collision plate 204 and the storage barrel 101, and an extrusion column 208 is fixedly connected to the side wall of the first rotating shaft 203, and the extrusion column 208 can fit with the collision plate 204;

[0025] It should be noted that when molten salt is injected into the inner cavity of the heat exchange box 1 through the storage barrel 101, the first servo motor 202 is driven to drive the first rotating shaft 203 to rotate, and the first rotating shaft 203 drives the extrusion column 208 to collide with the collision plate 204, so that the collision plate 204 drives the connecting column 205 to slide downwardly of the storage barrel 101, thereby causing the connecting column 205 to drive the concave plate 206 to slide downwardly. At this time, the spring 207 is squeezed to generate a rebound force. When the extrusion column 208 is away from the collision plate 204, the collision plate 204 returns to its original position under the action of the rebound force of the spring 207, and waits for the next collision, thereby causing the concave plates 206 on both sides of the storage barrel 101 to slide up and down in turn, thereby avoiding the accumulation of molten salt in the inner cavity of the storage barrel 101, and then causing the inner cavity of the storage barrel 101 to be blocked.

[0026] Reference Figure 1-4 The discharging assembly 3 includes a connecting pipe 301, which is fixedly mounted on the bottom of the heat exchange box 1, and a second servo motor 302 is fixedly connected to the side wall of the connecting pipe 301;

[0027] The output end of the second servo motor 302 is fixedly connected to the second rotating shaft 303, and the side wall of the second rotating shaft 303 is fixedly connected to the spiral piece 304;

[0028] It should be noted that: driving the second servo motor 302 drives the second rotating shaft 303 to rotate, thereby driving the spiral piece 304 on the side wall of the second rotating shaft 303 to rotate, and then promoting the molten salt in the inner cavity of the connecting pipe 301 to be transferred to the outside of the connecting pipe 301 to complete the discharge.

[0029] Reference Figure 1-4 The top of the storage barrel 101 is fixedly connected to the feed box 4, the inner wall of the feed box 4 is rotatably connected to a rotating column, and the side wall of the rotating column is fixedly connected to a plurality of rotating plates 401, and the rotating plates 401 are in contact with the inner wall of the feed box 4;

[0030] The inner wall of the storage barrel 101 is fixedly connected with a first semicircular plate 402, and the bottom end of the first rotating shaft 203 is fixedly connected with a second semicircular plate 403, and the first semicircular plate 402 and the second semicircular plate 403 can separate the storage barrel 101;

[0031] The side walls of the heat exchange box 1 are fixedly connected with a water inlet pipe 404 and a water outlet pipe 405, and the top of the collision plate 204 is set to an arc shape;

[0032] It should be noted that: molten salt is added to the inner cavity of the storage barrel 101 through the feed box 4, and the rotating rotating plate 401 can make the molten salt enter the inner cavity of the storage barrel 101 in an orderly manner, and when driving the first servo motor 202 to drive the first rotating shaft 203 to rotate to avoid blockage in the inner cavity of the storage barrel 101, the first rotating shaft 203 will also drive the second semicircular plate 403 to rotate. When the second semicircular plate 403 rotates, the molten salt in the inner cavity of the storage barrel 101 can enter the interior of the heat exchange box 1. When the first semicircular plate 402 and the second semicircular plate 403 are symmetrical, the storage barrel 101 is blocked and the molten salt cannot be injected, thereby controlling the amount of molten salt injected into the inner cavity of the heat exchange box 1 by the storage barrel 101, and the water outlet pipe 405 and the water inlet pipe 404 can control the entry of hot and cold water into the inner cavity of the heat exchange box 1 for heat exchange operation.

[0033] Operation method: molten salt is added to the inner cavity of the storage barrel 101 through the feed box 4, wherein the rotating rotating plate 401 can make the molten salt enter the inner cavity of the storage barrel 101 in an orderly manner, driving the first servo motor 202 to drive the first rotating shaft 203 to rotate, and the first rotating shaft 203 will also drive the second semicircular plate 403 to rotate. When the second semicircular plate 403 rotates, the molten salt in the inner cavity of the storage barrel 101 can enter the interior of the heat exchange box 1. When the first semicircular plate 402 and the second semicircular plate 403 are symmetrical, the storage barrel 101 is blocked and the molten salt cannot be injected. Therefore, the amount of molten salt injected into the inner cavity of the heat exchange box 1 by the storage barrel 101 is controlled;

[0034] When the first rotating shaft 203 rotates, it will also drive the extrusion column 208 to collide with the collision plate 204, so that the collision plate 204 drives the connecting column 205 to slide downwardly in the storage barrel 101, thereby causing the connecting column 205 to drive the concave plate 206 to slide downwardly. At this time, the spring 207 is squeezed to generate a rebound force. When the extrusion column 208 is away from the collision plate 204, the collision plate 204 returns to its original position under the rebound force of the spring 207, and waits for the next collision, thereby causing the concave plates 206 on both sides of the storage barrel 101 to slide up and down in turn, thereby avoiding the accumulation of molten salt in the inner cavity of the storage barrel 101, thereby causing the inner cavity of the storage barrel 101 to be blocked, driving the second servo motor 302 to drive the second rotating shaft 303 to rotate, thereby driving the spiral piece 304 on the side wall of the second rotating shaft 303 to rotate, thereby prompting the molten salt in the inner cavity of the connecting pipe 301 to be transferred to the outside of the connecting pipe 301, completing the discharge.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
