Description

Technical Field

[0001] The utility model relates to the technical field of metallic sodium production equipment, in particular to a stirring device for liquid metallic sodium. Background Art

[0002] After electrolysis in an electrolytic cell, the content of calcium in the produced liquid metallic sodium is relatively high and cannot meet the product quality requirements. It is necessary to send the liquid metallic sodium to the next process for purification and refinement. During the transfer process of the liquid metallic sodium, the liquid metallic sodium is stored in a sodium collecting tank, and then the liquid discharge port of the sodium collecting tank is connected to a refiner, so that the liquid sodium in the sodium collecting tank is discharged into the refiner for refinement. Since metallic calcium in the liquid sodium will settle to the bottom of the sodium collecting tank, affecting the discharge of the liquid sodium, before discharging the liquid metallic sodium into the refiner, it is necessary to stir the liquid sodium in the sodium collecting tank.

[0003] Currently, when stirring the liquid sodium in the sodium collecting tank in the workshop, a special wrench is used to connect the stirring shaft of the sodium collecting tank, and workers use the wrench to stir manually, which is time-consuming and laborious, and the stirring effect is not good; moreover, the connection between the sodium collecting tank and the refiner is a rigid connection, and it is necessary for workers to frequently move the sodium collecting tank on the ground to achieve docking with the refiner. The process of moving and docking is time-consuming and laborious, with low efficiency. Frequent movement of the sodium collecting tank not only generates a large amount of workload, but also poses a great safety hazard, greatly affecting the production operation efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a stirring device for liquid metallic sodium, which is used to improve the stirring efficiency and effect of the liquid sodium in the sodium collecting tank, making the discharge of the liquid sodium smoother; at the same time, it improves the docking efficiency between the sodium collecting tank and the refiner, and improves the production operation efficiency.

A clamping groove is formed on the top surface of the coupling ring, the coupling ring is slidably sleeved on the connection sleeve, the cross bar fixed on the connection sleeve is clamped in the clamping groove, and a connection port is formed on the connection sleeve.

[0006] Further, the universal coupling assembly includes two couplings connected by a coupling joint.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1 to 13As shown in the figure, this embodiment provides a liquid metal sodium stirring device, which includes a bracket 1, a driving motor 2, and a universal coupling assembly 3. The bottom end of the bracket 1 is fixed to the ground, and a driving motor 2 with an output shaft facing downward is fixed at the top of the bracket 1, which can achieve forward and reverse rotation. According to actual needs, a driving motor 2 with a speed reducer can be selected to meet the stirring speed requirements of the process. The universal coupling assembly 3 includes two couplings 3.1 connected by a coupling joint 3.2. A connecting piece is sleeved and fixed on the output shaft of the driving motor 2, and the top end of the upper coupling 3.1 is fixedly connected to the connecting piece by screws. The bottom end of the universal coupling assembly 3 is connected to the top surface of the coupling ring 4.1 of the connecting assembly 4. The connecting assembly 4 includes a coupling ring 4.1, a connecting sleeve 4.2, and a cross bar 4.3. Two symmetrical card slots 4.11 are opened on the top surface of the coupling ring 4.1. The coupling ring 4.1 is slidably sleeved on the connecting sleeve 4.2, and a cross bar 4.3 clamped in the card slots 4.11 is welded and fixed on the connecting sleeve 4.2. A connection port 4.21 is opened on the connecting sleeve 4.2. The connection port 4.21 is square, and the shape of the end of the stirring shaft of the sodium collecting tank is adapted to the connection port 4.21. The connection port 4.21 is inserted into the end of the stirring shaft of the sodium collecting tank. Driven by the driving motor 2, the power is transmitted from the universal coupling assembly 3 to the stirring shaft through the connecting assembly 4, so as to stir the liquid sodium in the sodium collecting tank and ensure its smooth discharge. Therefore, the utility model can meet the quick and effective connection between the connecting sleeve 4.2 and the sodium collecting tank at a given placement position by setting the universal coupling assembly 3 on the premise of ensuring the effective docking of the liquid discharge port of the sodium collecting tank and the refiner.

[0029] During the power transmission process, the universal coupling assembly 3 first transmits the force to the coupling ring 4.1 of the connecting assembly 4, drives the cross bar 4.3 through the edges of the two card slots 4.11 on the coupling ring 4.1, then drives the connecting sleeve 4.2 to rotate by the cross bar 4.3, and further drives the stirring shaft to act by the connecting sleeve 4.2. When there is a large amount of metallic calcium deposited at the bottom of the sodium collecting tank, it will cause a large resistance to the blades at the bottom of the stirring shaft. In order to avoid damage to the universal coupling assembly 3 or the driving motor 2, the utility model sets the connecting sleeve 4.2 and the cross bar 4.3 which are welded to each other and have relatively weak bearing capacity. When the force is large, the connecting sleeve 4.2 and the cross bar 4.3 are separated first, blocking the power transmission, and thus playing an effective protective role for the universal coupling assembly 3 and the driving motor 2. Therefore, the utility model can effectively protect the safety of the equipment on the premise of improving the stirring efficiency and ensuring the stirring effect.

[0030] Each coupling 3.1 includes a cross joint 3.11 and a bushing 3.12 integrally formed with one end of the cross joint 3.11. A spline groove 3.121 is formed in the bushing 3.12. A spline shaft 3.13 is slidably inserted into the spline groove 3.121. One end of the spline shaft 3.13 is integrally formed with a smooth shaft 3.14 coaxially. The end of the smooth shaft 3.14 is fixedly connected to the coupling 3.2. The bushing 3.12 of the next coupling 3.1 can slide telescopically along the corresponding spline shaft 3.13. The spline shaft 3.13 of the previous coupling 3.1 can also slide telescopically in the corresponding bushing 3.12 after being stressed. The utility model can not only meet different placement positions but also meet the connection of sodium collection tanks at different heights. A retaining ring 3.15 is fixedly installed on the end face of the bushing 3.12 and slidably sleeved on the smooth shaft 3.14. The retaining ring 3.15 plays an effective limiting role on the spline shaft 3.13 to prevent it from slipping out of the corresponding bushing 3.12.

[0031] It further includes a universal ball table 5 placed below the connection assembly 4. The universal ball table 5 includes a chassis 5.1, a bottom cover 5.2 and balls 5.4. The bottom of the chassis 5.1 is fixed to the ground by bolts. A retaining ring 5.5 is fixedly installed on the top edge of the top surface of the chassis 5.1. A plurality of columns 5.3 are fixedly installed on the top surface of the chassis 5.1 inside the retaining ring 5.5. The balls 5.4 are rotatably embedded in the top surfaces of the columns 5.3. The bottom cover 5.2 that is in rolling contact with the balls 5.4 is covered on the chassis 5.1. The retaining ring 5.5 plays an effective limiting role on the bottom cover 5.2 to prevent it from slipping off the balls 5.4. The sodium collection tank is placed on the top surface of the bottom cover 5.2. When the placement position of the sodium collection tank has a large deviation from the position of the refiner and cannot be normally connected, the sodium collection tank can be easily moved manually to drive the bottom cover 5.2 to move on the balls 5.4, realizing the simple and efficient connection between the sodium collection tank and the refiner, avoiding the traditional laborious and frequent manual movement of the sodium collection tank, effectively reducing the labor intensity, and avoiding the safety hazards during the damage of the sodium collection tank and the movement process.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
