Description

TECHNICAL FIELD

[0001] The utility model belongs to lithium salt conveying technical field, concretely relates to a lithium salt speed control feeding device. BACKGROUND

[0002] In the lithium battery production and application field of new energy industry, lithium salt is an important raw material, and lithium salt will react chemically when it contacts with air. In the existing lithium salt unloading and feeding process, manual operation is often adopted, which inevitably exposes lithium salt to air, and the quality of lithium salt will be poor after reacting with air. In the air-tight space, it is difficult for manual operation to unload and feed lithium salt

[0003] The applicant previously applied for a Chinese patent with application number 2022114174605, which discloses a full-automatic lithium salt feeding device. The device includes a ton barrel, which is placed on a mounting frame. The ton barrel is installed with a discharge nozzle at the lower end. The mounting frame is movably installed in the middle of the rack through a lifting mechanism. The lower end of the rack is movably installed on a translation mechanism. The lifting mechanism and the translation mechanism are both electrically connected with a plurality of travel switches. A sending tank is fixedly installed on the tank frame at the middle position of one end of the translation mechanism. The ton barrel moves a certain distance to the top of the sending tank through the translation mechanism and the lifting mechanism. The discharge nozzle of the ton barrel is downwardly and sealingly connected to the feeding port of the sending tank through a flexible docking positioning mechanism.

[0004] The above-mentioned scheme realizes the action of full-automatic sealed feeding, which reduces the labor cost. However, when lithium salt is discharged from the discharge nozzle of the ton barrel, it is easy to be blocked at the discharge nozzle. Once the speed is reduced or the discharge is impossible, the discharge speed of the ton barrel is affected, which leads to uncontrollable discharge speed of the ton barrel. UTILITY MODEL CONTENTS

In summary, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances for the ordinary skilled in the art. Example 1

[0022] As Figure 1As shown, a lithium salt speed control feeding device includes a barrel 1, a support 2 connected around the barrel 1, the barrel 1 supported by the support 2, a discharge pipe 3 provided at the bottom of the barrel 1, a speed regulating conveying mechanism provided at the bottom of the discharge pipe 3, lithium salt stored in the barrel 1 entering the speed regulating conveying mechanism through the discharge pipe 3 and being conveyed and fed by the speed regulating conveying mechanism. A butterfly valve is provided at the discharge pipe 3, which can accurately control the speed of lithium salt flowing out of the barrel 1 by adjusting the opening of the butterfly plate. When the feeding speed needs to be accelerated, the opening of the butterfly plate can be increased; otherwise, when the feeding speed needs to be slowed down or the feeding amount needs to be accurately controlled, the opening of the butterfly plate can be reduced. The ability of precise adjustment helps to ensure the stability and accuracy of feeding.

[0023] In combination Figure 2 , the speed regulating conveying mechanism includes a conveying pipe 4 and a driving device, a conveying auger 5 is rotatably arranged in the conveying pipe 4, a feeding port 6 is provided above the conveying pipe 4, the feeding port 6 is connected with the discharge pipe 3, a feeding port 7 is provided below the conveying pipe 4 away from the feeding port 6, the driving device includes a driving motor 8, the output end of the driving motor 8 extends into the conveying pipe 4 and is connected with the conveying auger 5, after lithium salt is conveyed into the conveying auger 5, the conveying auger 5 is driven to rotate by the driving motor 8, and the lithium salt is conveyed to the feeding port 7 for feeding. The cooperation of the conveying pipe 4, the conveying auger 5 and the driving motor 8 enables the conveying speed of lithium salt to be accurately adjusted according to production requirements. This control method not only improves the stability of the discharge speed, but also ensures the continuity and consistency of the production process, which is beneficial to improve the product quality and production efficiency.

[0024] A vibration motor 9 is connected to the side of the barrel 1 by bolts, the outer shell of the vibration motor 9 is attached to the outer side wall of the barrel 1, and the vibration frequency and amplitude are set to drive the side of the barrel 1 to vibrate. By installing the vibration motor 9 on the side of the barrel 1 and working closely to the outer side wall of the barrel 1, the device can effectively vibrate the barrel 1, prevent lithium salt from accumulating at the discharge nozzle and the inner side wall of the barrel 1, and thus significantly reduce the risk of blockage. This active anti-blocking measure is the core advantage of the scheme, which can ensure smooth discharge and avoid production interruption.

[0025] In combination Figure 1The side of the discharge pipe 3 is connected with a negative pressure flow pipe 10, the top of the barrel 1 is provided with a negative pressure extraction pump 11, the negative pressure extraction pump 11 is connected with the negative pressure flow pipe 10, the negative pressure flow pipe 10 is provided with a control switch valve 12, the negative pressure extraction pump 11 can generate negative pressure to adsorb the lithium salt at the discharge pipe 3 to the top of the barrel 1, so as to avoid the discharge port of the barrel 1 to stop. The lithium salt at the bottom of the discharge pipe 3 accumulates and forms a blockage. The negative pressure extraction pump can generate negative pressure, and the lithium salt at the discharge pipe 3 is adsorbed to the top of the barrel 1 through the negative pressure flow pipe 10. This design fundamentally solves the problem of blockage caused by the accumulation and caking of lithium salt at the discharge pipe 3. Even when the discharge speed slows down or stops, the discharge pipe 3 can still be kept unobstructed, avoiding the blockage caused by the accumulation at the bottom in the traditional way. Especially when dealing with lithium salt with high viscosity or easy caking, this effect is more obvious. By reducing the risk of blockage, the design enhances the stability and reliability of the equipment. In the process of continuous production for a long time, the stable discharge speed can be maintained to ensure the continuity and consistency of the production process.

[0026] In combination Figure 3 The inside top of the barrel 1 is connected with a support, the support extends to the inside top of the barrel 1 and is connected with a stirring motor 14, the bottom output end of the stirring motor 14 is connected with a stirring shaft 15, and the bottom of the stirring shaft 15 extends to the bottom of the barrel 1 and is connected with stirring blades 16. The operation of the stirring motor 14 can continuously stir the lithium salt in the barrel 1, effectively preventing the material from accumulating and caking at the bottom or sidewall of the barrel 1. This is crucial for maintaining the flowability of lithium salt and the smoothness of discharge, avoiding the problem of blockage caused by caking. The rotation of the stirring blades 16 not only prevents caking, but also promotes the uniform mixing of lithium salt in the barrel 1. This is particularly important for production processes that require precise control of raw material ratios, ensuring the accuracy of feeding and the stability of product quality.

[0027] In combination Figure 4 The stirring blades 16 include a flat plate structure and a twisted plate structure 18 connected with the flat plate structure, and the flat plate structure and the twisted plate structure 18 are detachably connected. The detachable connection can be bolted or any other connection structure. The combination of the flat plate structure and the twisted plate structure 18 can promote the mutual collision and shearing between lithium salts, further improving the possibility of avoiding blockage.

[0028] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
