Description

Technical Field

[0001] This invention belongs to the field of molten salt melting technology, specifically a chlor-alkali molten salt melting device. Background Technology

[0002] Currently, the domestic chlor-alkali chemical industry has a caustic soda flake production capacity of 13-15 million tons. Fukang Energy's chlor-alkali plant has a solid caustic soda production capacity of 750,000 tons / year. Its solid caustic soda unit uses a molten salt system as the heat exchange medium. The molten salt is a mixture of 40% NaNO2, 7% NaNO3, and 53% KNO3. By heating the final concentrator with the molten salt, the caustic soda solution is concentrated from 62% to 98%. Furthermore, the molten salt is used for heat tracing in the molten caustic soda pipelines, flash evaporator EV-2311, and distributor V-2312. Molten salt is stored in molten salt tank T-6101. A molten salt pump is installed above the molten salt tank. Steam preheats, melts, and maintains the temperature of the molten salt through coils inside and outside the molten salt tank. At the same time, the molten salt passes through the molten salt circulation pump (P-6101) and then through the molten salt heating furnace (H-6101), where it is heated to 405℃-430℃. The flue gas from the molten salt furnace passes through an air preheater, which heats the combustion air from BL-6101 from ambient temperature to approximately 260℃. The cooled flue gas is then discharged into the atmosphere through a chimney (D-6104). An electromagnetic heater is installed at the bottom of the molten salt tank, allowing the tank to heat itself. The electromagnetic heating power is controlled by a temperature sensor. This design breaks through and replaces the steam preheating of the molten salt system, enabling the new unit to complete molten salt melting in one day, greatly shortening the commissioning time of the new unit. At the same time, it can maintain the temperature of the molten salt system when the unit is shut down, eliminating the energy waste caused by starting the molten salt pump and heating.

[0003] For example, patent CN216396287U discloses a rapid heating and melting device for molten salt, including a base plate. Support plates are fixedly connected to both sides of the top of the base plate. A melting device body is disposed inside the support plates. A cover plate is movably connected to the top of the melting device body. A transmission mechanism is movably connected to the top of the support plates. By setting the transmission mechanism, the melting device body can be moved upwards. Then, through a cylinder, the melting device body can be pushed back and forth to avoid dead corners inside the melting device body, thereby achieving the effect of rapid melting. This solves the problem that existing rapid heating and melting devices for molten salt cannot perform rapid melting. This rapid heating and melting device for molten salt has the advantage of rapid melting, and there are no dead corners inside the device during use, thus ensuring the processing efficiency of the rapid heating and melting device for molten salt.

[0004] In existing technologies, a hydraulic structure is used to drive the melting device to swing. During the swinging process, dead corners can be avoided inside the body, which can accelerate melting to a certain extent and thus increase the melting speed. However, the existing swinging structure can only achieve reciprocating swinging, and there will still be liquid stagnation in the areas on both sides. After stirring, the solution on both sides may be unevenly melted. Summary of the Invention

[0010] Preferably, the linkage locking assembly includes a rotating sleeve, with stabilizing slip rings installed on both sides of the rotating sleeve, an adjusting motor installed at the bottom of the rotating sleeve, and a worm gear transmission assembly provided at the output end of the adjusting motor.

[0012] Preferably, the push block is movably disposed above the fixed plate, a locking rod is installed on the top of the movable plate, and the locking rod is slidably inserted into the inner side of the locking groove. The top of the inner side of the lifting trapezoidal platform and the movable plate are elastically connected by a return spring.

[0013] Preferably, the linkage locking assembly includes two sets of welding sleeves. The rotating sleeve is rotatably disposed inside the two sets of welding sleeves. A combined bearing is fixedly disposed on the inner side of the welding sleeve away from the rotating sleeve. A rotating platform is rotatably disposed on the inner side of the combined bearing. A welding guide rod is installed in the middle of the rotating platform. A movable plate is slidably disposed on the outer side of the welding guide rod. A locking rod is installed on the top of the movable plate. The locking rod is movably inserted into the top of the inner side of the welding sleeve.

[0014] Preferably, the movable plate is welded and installed on both sides of the lifting trapezoidal platform, and two sets of limiting guide rods are installed between the two sets of rotating sleeves. A pressing tilting platform is slidably arranged on the outer side of the limiting guide rod, and the pressing tilting platform is located below the lifting trapezoidal platform.

[0015] Preferably, a support platform is installed at the bottom of the two sets of welding sleeves, and a main support is welded to the top of the support platform. The positioning rotating sleeve is fixedly installed on the inner side of the upper end of the main support.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the combination of a shaking component and a ball joint end, facilitates the expansion of the melting cylinder through circular rotation, achieving uniform shaking. Combined with the internal fixing rod, this creates a stirring effect. A drive motor rotates and adjusts the connecting seat and arc-shaped guide frame. An electric winch with a steel cable releases and adjusts the tilt angle of the melting cylinder and the combined cover. During adjustment, the weight of the melting cylinder itself causes the sliding column to slide along the arc-shaped guide frame, adjusting the angle of the melting cylinder to suit different needs. The drive motor then rotates the arc-shaped guide frame at the output end, expanding the combined cover, melting cylinder, and ball joint end to shake uniformly along the ball joint seat. During this shaking, the internal solution flows synchronously, contacting and being diverted by the internal fixing rod, thus achieving uniform stirring. This effectively avoids the problem of normal stirring structures failing to operate properly due to molten salt solidification during internal rotation, significantly improving the shaking and stirring effect.

[0017] This invention, through the coordination of a linkage locking component and a ball joint end, facilitates the expansion of the melting cylinder structure and its combination with the combined cover via adjustment. This ensures the combined cover restricts the melting cylinder while locking the lower rotating structure to prevent interference with the upper stirring structure. Adjusting the motor, in conjunction with the worm gear transmission component, expands the rotation of the reverse screw. During rotation, the threaded structure of the reverse screw drives the adjusting sleeve and the inclined extrusion table to move towards the center. This movement pushes and lifts the central lifting trapezoidal platform, which in turn raises the ball joint end. The locking rod is then inserted into the welding sleeve for locking. Simultaneously, during lifting, the locking rod separates from the locking groove, allowing the ball joint end to rotate freely. Furthermore, during lifting, the melting cylinder is inserted into the inside of the combined cover for locking. This linkage adjustment ensures the device functions correctly.

[0021] like Figures 1 to 7 As shown, the present invention provides a chlor-alkali molten salt melting device, including a melting cylinder 100, and a shaking component 002 is provided on the top of the melting cylinder 100; The mixing assembly 002 includes an arc-shaped guide frame 503. A sliding column 505 is slidably arranged on the inner side of the arc-shaped guide frame 503, and a combined cover 507 is installed at the bottom of the sliding column 505.

An electric winch 509 is installed on one side of the arc-shaped guide frame 503, and steel wire ropes 500 are wound on the inner sides of both ends of the electric winch 509. Two sets of limiting ends 106 are installed on the side of the melting cylinder 100 near the steel wire ropes 500. The end of the steel wire rope 500 away from the electric winch 509 is rotatably arranged inside the limiting end 106. An electromagnetic heating ring 102 is embedded in the lower end of the melting cylinder 100.

[0022] Using the above scheme: the melting cylinder 100 can provide storage space for molten salt. The molten salt inside can be rapidly heated by electromagnetic heating through the bottom electromagnetic heating ring 102 and the electromagnetic heater 103. The inner structure can be restricted by the arc-shaped guide frame 503. The sliding column 505 can slide and adjust its position along the inner side of the arc-shaped guide frame 503 in conjunction with the sliding ring 506. The electric winch 509 can provide tension. By releasing the length, the angle of the melting cylinder 100 and the combined cover 507 can be adjusted along the lower earth hinge end 107. The limiting end 106 can be used to connect and restrict the end of the wire rope 500 to assist in angle adjustment.

[0023] like Figure 1 and Figure 2 As shown, a limiting arc groove 504 is provided on the inner side of the arc-shaped guide frame 503, and a sliding ring 506 is installed on the outer side of the sliding column 505. The sliding ring 506 is slidably disposed on the inner side of the limiting arc groove 504. A connecting seat 502 is welded and installed on the top of the arc-shaped guide frame 503 near the electric winch 509.

[0024] A positioning rotating sleeve 501 is installed on the top of the connecting seat 502, and a drive motor 508 is installed on the top of the positioning rotating sleeve 501 by bolts. The output end of the drive motor 508 is fixedly connected to the connecting seat 502.

[0025] Several sets of fixing rods 101 are installed on the bottom of the inner side of the melting cylinder 100. The input end of the electromagnetic heating ring 102 is connected to the electromagnetic heater 103, and the bottom of the electromagnetic heater 103 is connected to the slip ring 104 through the line. A ball joint end 107 is welded to the bottom of the melting cylinder 100, and a locking groove 108 is opened at the bottom of the ball joint end 107. A flow guide port 105 is opened on one side of the upper end of the melting cylinder 100, and a linkage locking component 001 is provided on the outer side of the lower end of the ball joint end 107.

[0026] Using the above scheme: the limiting arc groove 504 can restrict the inner sliding ring 506, assist in sliding adjustment, and avoid positional deviation. The connecting seat 502 can be used to rotate the bottom arc guide frame 503 and the positioning rotating sleeve 501 to ensure the rotational stability of the structure. The drive motor 508 can provide driving force and control the rotational adjustment of the arc guide frame 503. The fixed rod 101 can assist in stirring the internal flowing liquid. The electromagnetic heater 103 can assist in power supply. The electric slip ring 104 fixed on the top of the ball joint seat 201 can be connected to the circuit to ensure stable power supply. The ball joint seat 201 can rotate the ball joint end 107 to ensure that the ball joint end 107 can rotate stably inside. The guide port 105 can guide the internal liquid to pour out.

[0027] like Figures 3-6 As shown, the linkage locking assembly 001 includes a rotating sleeve 301, with stabilizing slip rings 302 installed on both sides of the rotating sleeve 301, an adjusting motor 303 installed at the bottom of the rotating sleeve 301, and a worm gear transmission assembly 304 provided at the output end of the adjusting motor 303. A reverse lead screw 300 is installed at the output end of the worm gear transmission assembly 304, and a fixed plate 305 is installed at the top of the worm gear transmission assembly 304.

[0028] The linkage locking component 001 includes a lifting trapezoidal platform 200, a ball joint seat 201 is installed on the top of the lifting trapezoidal platform 200, the ball joint end 107 is rotatably disposed inside the ball joint seat 201, a movable disk 202 is movably disposed inside the lifting trapezoidal platform 200, and a push block 205 is installed at the bottom of the movable disk 202.

[0029] The push block 205 is movably positioned above the fixed plate 305. A locking rod 203 is installed on the top of the movable plate 202, and the locking rod 203 slides into the inner side of the locking groove 108. The top of the inner side of the lifting trapezoidal platform 200 and the movable plate 202 are elastically connected by a return spring 204.

[0030] The linkage locking assembly 001 includes two sets of welding sleeves 401. A rotating sleeve 301 is rotatably disposed inside the two sets of welding sleeves 401. A combined bearing 402 is fixedly disposed inside the end of the welding sleeve 401 away from the rotating sleeve 301. A rotating platform 403 is rotatably disposed inside the combined bearing 402. A welding guide rod 404 is installed in the middle of the rotating platform 403. A movable plate 400 is slidably disposed on the outer side of the welding guide rod 404. A locking rod 405 is installed on the top of the movable plate 400. The locking rod 405 is movably inserted into the top of the inner side of the welding sleeve 401.

[0031] The movable plate 400 is welded and installed on both sides of the lifting trapezoidal platform 200. Two sets of limiting guide rods 406 are installed between the two sets of rotating sleeves 301. A pressing tilting platform 407 is slidably arranged on the outside of the limiting guide rods 406, and the pressing tilting platform 407 is located below the lifting trapezoidal platform 200. An adjusting screw sleeve 408 is installed at the bottom of the pressing tilting platform 407, and the adjusting screw sleeve 408 is slidably arranged on the outside of the reverse screw 300.

[0032] Using the above scheme: the rotating sleeve 301 can rotate and adjust along the inner side of the welded sleeve 401. The stabilizing slip ring 302 can increase the stability of the rotating connection of the welded sleeve 401, ensuring rotational stability. The adjusting motor 303 can provide the adjusting driving force, which, together with the worm gear transmission assembly 304, can drive the reverse screw 300 to rotate and adjust. During the adjustment, the threaded structure can be used to drive the adjusting screw sleeve 408 to move towards the center or in the opposite direction. The fixed plate 305 can block the falling push block 205, preventing the push block 205 from falling synchronously with the lifting trapezoidal platform 200. The movable plate 202 can be raised and adjusted under the action of the push block 205. The locking rod 203 can be inserted into the inner side of the locking groove 108 under the obstruction of the movable plate 202 to achieve the locking effect. The welded sleeve 401 can restrict the inner structure, and the combined bearing 402 can assist. The rotating table 403 is rotated and adjusted, and the limiting guide rod 406 can connect the two sets of rotating tables 403 to ensure the integrity. At the same time, the limiting guide rod 406 can restrict the outer sliding extrusion tilting table 407. The movable plate 400 can move up and down along the inner side of the welding guide rod 404. During the adjustment, the locking rod 405 will be embedded in the top of the inner side of the welding sleeve 401 to achieve the locking effect. After locking, the rotating sleeve 301 and the top structure will not be able to rotate and adjust normally. It should be noted that the rotation of the rotating sleeve 301 inside the welding sleeve 401 is limited, and it can only rotate 90 degrees in one direction. At the same time, the bottom of the lifting trapezoidal platform 200 is evenly provided with several sets of roller-like structures to ensure the smoothness of contact with the extrusion tilting table 407. The sliding ring 506 has a certain friction on the inner side of the limiting arc groove 504. Without the application of force, the sliding ring 506 will not slide.

[0033] A support platform 601 is installed at the bottom of the two sets of welding sleeves 401, and a main support 600 is welded and installed on the top of the support platform 601. The positioning rotating sleeve 501 is fixedly installed on the inner side of the upper end of the main support 600.

[0034] Using the above scheme: the support platform 601 can provide support for the top structure, and the main support 600 can rotate and adjust the inner positioning rotating sleeve 501, while also stabilizing and restricting the inner structure.

[0035] The working principle and usage process of this invention are as follows: Chlor-alkali molten salt material is poured into the inner side of the melting cylinder 100. Then, the motor 303, in conjunction with the worm gear transmission assembly 304, drives the reverse screw 300 to rotate. During rotation, the screw thread drives the adjusting sleeve 408 and the extrusion tilting table 407 to move towards the center. During this movement, the tilting surface pushes the lifting trapezoidal platform 200 to move stably upwards. During this movement, the locking rod 405 of the movable plate 400 will be embedded in the top of the inner side of the welding sleeve 401 to achieve a locking effect. Simultaneously, during the lifting, the pushing block 205 separates from the fixed plate 305. After separation, under the push of the return spring 204, the locking rod 203 separates from the locking groove 108 of the ball joint end 107. During the separation process, the upper end of the melting cylinder 100 will be spliced ​​with the combined cover 507. Then, the electric winch 509 is used to release the wire rope 500, thereby driving the melting cylinder 100, the combined cover 507 and the sliding column 505 to adjust the angle along the ball joint end 107. After the adjustment is completed, the drive motor 508 controls the arc guide frame 503 to rotate, thereby driving the melting cylinder 100 and the ball joint end 107 to rotate and sway along the ball joint seat 201. During the swaying process, the electromagnetic heating ring 102 will heat the molten salt inside, and the liquid molten salt will accelerate the mixing after hitting the fixed rod 101. Finally, the melting cylinder 100 is adjusted to be perpendicular to the ground, and the adjustment motor 303 is used to unlock it. After unlocking, the wire rope 500 is released again. Under the action of gravity, the rotating sleeve 301 and the overall structure at the upper end rotate 90 degrees along the inner side of the welding sleeve 401, thereby pouring out the molten salt inside.
