Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte storage devices, specifically an electrolyte storage device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors, also known as capacitors, are energy storage elements. Their structures can be divided into three types: fixed capacitors, semi-variable capacitors, and variable capacitors. In circuits, they function as tuners, filters, couplers, bypasses, converts energy, and delays. Structurally, an aluminum electrolytic capacitor consists of an aluminum cylinder as the negative electrode, filled with a liquid electrolyte, and a bent aluminum strip inserted as the positive electrode. The electrolyte, as the discharge medium of the battery, provides ion channels for the normal operation of the positive and negative electrodes. It is generally composed of high-purity organic solvents, lithium electrolyte salts, and necessary additives, mixed under certain conditions and in certain proportions. For convenient access and stable storage, the electrolyte is usually stored in a sealed electrolyte storage device.

[0003] The use of electrolyte is mainly divided into two cases: quantitative and non-quantitative. Existing aluminum electrolytic capacitor electrolyte storage devices mostly adopt quantitative discharge structures for quantitative dispensing. However, due to the limitations of the quantitative dispensing structure, its efficiency is extremely low when dispensing large amounts of non-quantitative materials, and it is very inconvenient to use. Therefore, an aluminum electrolytic capacitor electrolyte storage device is proposed. Utility Model Content

The tank structure is used for electrolyte storage and includes a storage tank 1, a drive motor 2, and a stirring rod 3, as shown in the attached figure. Figure 3 As shown, the storage tank 1 adopts a vertical working installation structure. To facilitate the placement and support of the storage tank 1, a bottom support column 4 is fixedly installed at the bottom of the storage tank 1. To improve the heat insulation characteristics of the tank, the cylindrical wall of the storage tank 1 is double-layered, as shown in the attached figure. Figure 1 As shown, in order to facilitate the filling of electrolyte, a feed inlet is provided at the top of the storage tank 1. In order to facilitate the observation of electrolyte storage, a liquid level window 5 is provided on the middle side of the storage tank 1. The liquid level window 5 is sealed with explosion-proof glass. In order to facilitate liquid level measurement, a liquid level scale is provided on the outer side of the liquid level window 5.

[0027] The stirring rod 3, driven by the drive motor 2 to rotate on a fixed shaft, is installed inside the storage tank 1 for stirring and mixing the electrolyte, as shown in the attached diagram. Figure 3 As shown, the drive motor 2 is fixedly installed on the upper part of the storage tank 1 by bolts, and the stirring rod 3 is fixedly and rotatably installed on the inner side of the storage tank 1 by a shaft column. The shaft column end of the stirring rod 3 is fixedly installed with the rotating shaft end of the drive motor 2. The electrolyte in the storage tank 1 can be mixed and stirred by the rotating stirring rod 3 driven by the drive motor 2.

[0028] The discharge mechanism is installed on the lower discharge side of the storage tank 1. The discharge mechanism includes a discharge seat 6, a straight cylindrical material pipe 7, a drive cylinder 8, a sliding plug seat 9, and a sealing top seat 10. The straight cylindrical material pipe 7 is connected to the lower part of the storage tank 1 via the discharge seat 6. Specifically, see attached... Figure 2 As shown, the discharge seat 6 is fixedly installed to the lower opening side of the storage tank 1 by bolts. The straight cylindrical material pipe 7 is cylindrical and is vertically fixedly installed to the lower part of the discharge seat 6. For convenient discharge connection, see attached... Figure 4 As shown, a discharge connecting seat is provided at the lower part of the straight cylindrical material tube 7, and the drive cylinder 8 is fixedly installed at the lower part of the discharge connecting seat by bolts.

[0029] Drive cylinder 8 is a servo electric cylinder, as shown in the attached image. Figure 5 As shown, the push rod end of the drive cylinder 8 movably passes through the discharge connecting seat. The sliding plug seat 9 is movably installed inside the straight cylindrical material tube 7 by the drive cylinder 8. A quantitative dispensing structure is adopted, using the straight cylindrical material tube 7 as a plug structure in conjunction with the sliding plug seat 9 driven by the drive cylinder 8 to form a piston-type quantitative dispensing structure, which can realize quantitative dispensing control of electrolyte. Specifically, the sliding plug seat 9 is plug-shaped, with a connecting insertion hole through its center. The push rod end of the drive cylinder 8 is movably inserted into the connecting insertion hole. The sliding plug seat 9 is movably installed with the push rod end of the drive cylinder 8 by the sealing top seat 10 pushing and limiting it. See attached diagram for details. Figure 6 As shown, to facilitate electrolyte flow, flow holes are evenly arranged on the upper part of the sliding plug seat 9. The connecting holes are circumferentially and evenly opened through the middle of the sliding plug seat 9. The sealing top seat 10 is fixedly installed on the upper end of the push rod of the drive cylinder 8 for sealing the flow holes when moving downward. To improve sealing stability, a sealing support 11 is fixedly installed on the lower part of the sealing top seat 10. To facilitate the upward push of the sliding plug seat 9 when moving upward, a limiting ring seat 12 is provided in the middle of the push rod of the drive cylinder 8. The limiting ring seat 12 is installed in contact with the sliding plug seat 9 for support. The sliding plug seat 9 adopts a floating installation structure. A sliding plug seat 9 with a flow hole is movably installed on the push rod end of the drive cylinder 8. Together with the sealing top seat 10 and the limiting ring seat 12 on the upper part of the push rod, it forms a variable valve plug structure. When the push rod moves upward, the sealing top seat 10 moves upward and opens, allowing the electrolyte to flow freely through the flow hole. It can be used as an absorption connection structure for quantitative material dispensing and a normally open high-efficiency connection structure for non-quantitative material dispensing. When the push rod moves downward and pulls, the sealing top seat 10 moves downward and closes the flow hole. It can be used as a push and discharge drive structure for quantitative material dispensing. The structure is simple and flexible to use. The quantitative and non-quantitative material dispensing needs of electrolyte can be met by a single set of discharge structures.

[0030] In order to seal the opening side of the discharge connector after the material is discharged downwards, as shown in the attached document. Figure 5As shown, a support ring seat is provided on the inner hole connecting the straight cylindrical material pipe 7 and the discharge connecting seat. In order to facilitate the discharge of electrolyte, a discharge end pipe 13 is fixedly connected to the side of the discharge connecting seat. The liquid inlet of the discharge end pipe 13 is located below the support ring seat. After the sliding plug seat 9 moves down to block it, the electrolyte above can be prevented from entering the discharge end pipe 13. In order to facilitate the on / off control of the discharge end pipe 13, a material taking valve is provided in the middle of the discharge end pipe 13.

[0031] The working principle or structural principle is as follows: When the electrolyte is taken out, the driving motor 2 drives the stirring rod 3 to stir and mix the electrolyte in the storage tank 1, so that the electrolyte is evenly distributed. When taking out non-quantitative amounts, the sliding plug seat 9 is positioned as shown in the attached figure. Figure 5 In the working state shown, the sealing top seat 10 is in the normally open, upward-moving state. Simply pull the opening valve on the upper part of the discharge end pipe 13, and the electrolyte in the storage tank 1 flows through the straight cylindrical material pipe 7 and the flow hole, directly discharged from the discharge end pipe 13, achieving efficient non-quantitative dispensing of the electrolyte. For quantitative dispensing, the dispensing parameters are set according to the dispensing requirements on the device's operation panel. Then, with the dispensing valve closed, driven by the drive cylinder 8, the sliding plug seat 9 is moved upward by the limiting ring seat 12. After reaching the set height, the slide plug 9 stops and moves downwards for a fixed stroke. During the downward movement, the sliding plug 9 remains stationary due to friction. At the same time, the push rod drives the sealing top seat 10 to move downwards and fit against the upper part of the sliding plug 9 to seal the flow hole. Then, the material valve at the top of the discharge end pipe 13 is opened, and the sliding plug 9 is driven downwards by the drive cylinder 8 to push the electrolyte in the straight tube 7 out. The sliding plug 9, after moving downwards, seals the liquid inlet side of the discharge end pipe 13 to prevent excess material from flowing out, thus completing the quantitative discharge work.

[0032] In summary, this storage device adopts a quantitative dispensing structure. The straight cylindrical material tube 7 serves as a plug structure, which, together with the sliding plug seat 9 driven by the drive cylinder 8, forms a piston-type quantitative dispensing structure. This enables quantitative dispensing control of the electrolyte. Furthermore, the sliding plug seat 9 adopts a floating installation structure, with the sliding plug seat 9, which has a flow hole, movably mounted on the push rod end of the drive cylinder 8. Together with the sealing top seat 10 and the limiting ring seat 12 on the upper part of the push rod, it forms a variable valve plug structure. When the push rod moves upward, the sealing top seat 10 moves upward and opens, allowing the electrolyte to flow freely through the flow hole. This can serve as an absorption connection structure for quantitative dispensing and a normally open, high-efficiency connection structure for non-quantitative dispensing. When the push rod moves downward, the sealing top seat 10 moves downward and closes the flow hole. This can serve as a push dispensing drive structure for quantitative dispensing. The structure is simple and flexible in use. The quantitative and non-quantitative dispensing requirements of the electrolyte can be met with a single dispensing structure.
