Description

Technical Field

[0001] The invention belongs to the technical field of electrolytic capacitors, and in particular relates to an electrolytic capacitor core deliquescence system and a deliquescence method used in the production process of electrolytic capacitors. Background Art

[0002] The production process of aluminum electrolytic capacitors includes cutting, winding, impregnation, assembly, aging, sealing, printing, casing, measurement, packaging and other processes. After the aluminum foil is sliced, it is synthesized and wound into a cylindrical battery structure on a winding machine by pressing a layer of electrolytic paper, anode foil, another layer of electrolytic paper, and cathode foil. Electrolytic paper is used as a cushioning layer between the anode foil and the cathode foil to prevent the two electrode foils from contacting and short-circuiting, and at the same time as a carrier for adsorbing and storing liquid working electrolyte. After winding, it needs to be impregnated. Impregnation is the process of immersing the element in the electrolyte. The electrolyte can further repair the dielectric layer. The electrolyte is a liquid that conducts electricity by ions. It is the true cathode and plays the role of connecting the dielectric layer on the surface of the anode aluminum foil. The cathode aluminum foil plays the role of connecting the true cathode and the internal circuit like the collector. The electrolyte is a key material that determines the characteristics of the capacitor (temperature characteristics, frequency characteristics, service life, etc.).

[0003] In the aluminum electrolytic capacitor industry, since the impregnation process involves the injection of electrolyte, when a certain amount of electrolyte is injected, excess electrolyte will be attached to the surface of the battery cell and in the interlayer of the electrolytic paper layer. Therefore, an effective tool to remove these excess attached electrolytes is needed. Currently, open centrifugal dehydration equipment is used. The electrolyte after the centrifugal dehydration equipment is in a collecting chute, and then discharged into a waste liquid container for unified scrapping. However, this process requires human intervention, which has high labor costs. In addition, the electrolyte that has been scrapped is prone to environmental pollution, which is not conducive to environmental protection, and wastes electrolyte and production materials, resulting in increased costs.

[0004] Therefore, in view of the defects of the above-mentioned prior art, it is necessary to carry out research and development to provide a solution that is convenient for reducing the production cost of aluminum electrolytic capacitors and does not pollute the environment by discharging waste liquid, which is beneficial to environmental protection.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Reference Figure 1 As shown in FIG. 5 , the electrolytic capacitor cell dehydration system of the present invention comprises a dehydration body 1, a driving motor 2, a base 3 supporting the dehydration body, and a vacuum liquid suction mechanism. The driving motor 2 is connected to the dehydration body 1 to drive the dehydration body 1 to work; the vacuum liquid suction mechanism is connected to the dehydration body 1 through a liquid suction tube.

[0034] Specifically, the deliquoring body 1 is cylindrical, and includes a protective shell 10, a cover 100 disposed on the protective shell 10, a storage bucket 11 disposed in the protective shell 10, and a battery carrier basket (not shown) placed in the storage bucket 11 for placing batteries; wherein, a ring-shaped inner edge portion 101 is extended inward from the top of the protective shell 10, and the angle between the extension direction of the ring-shaped inner extension portion 101 and the vertical direction of the protective shell 10 is greater than 90°, and the ring-shaped inner edge portion 101 forms a circular opening at the top of the protective shell; an outer edge portion is extended outward from the bottom edge of the protective shell 10, and a plurality of fixing legs are provided on the outer edge portion, and the protective shell 10 is tightly fixed to the base 3 by the fixing legs. In the embodiment of the present invention, the fixing legs are connected to the base 3 by screws; of course, they can also be directly welded and fixed to the base 3, or connected and fixed by other fixing methods. The cover 100 is arranged on the top of the protective shell 10 to cover the circular opening at the top of the protective shell.

[0035] The storage bucket 11 is arranged in the protective shell 10, and the outer diameter of the storage bucket 11 is smaller than the inner diameter of the protective shell 10, so that there is a gap between the outer wall of the storage bucket 11 and the inner wall of the protective shell 10. The storage bucket 11 is provided with two layers, the upper layer is a battery cell shelf layer, which is used to place the battery cell carrier basket; the battery cell is placed in the battery cell carrier basket, specifically, a plurality of battery cells are installed in a battery cell carrier basket in the form of an external cut of the battery cell cylinder circle, and the outer surfaces of the battery cell cylinders are in close contact with each other, so that the plurality of battery cells are squeezed against each other and stably placed in the battery cell carrier basket. The battery cell carrier basket is made of stainless steel material, and is circular or semicircular, and is provided with laminated fittings; the main body of the carrier basket is designed with mesh holes to allow the electrolyte to leak out; as another embodiment of the present invention, the carrier basket is also provided with a carrying handle. The lower layer is an electrolyte collection layer 110, which is used to place electrolyte; an annular platform is provided on the top of the receiving barrel 11, and the edge 112 of the receiving barrel 11 is bent inward to form an annular groove with the annular platform; a plurality of convex strips 111 are longitudinally provided on the inner wall of the receiving barrel 11, and the convex strips 111 protrude from the inner wall surface of the receiving barrel, and the vertical direction of the convex strips 111 is perpendicular to the bottom plane of the receiving barrel. The convex strips 111 can be integrally formed with the receiving barrel 11, or can be formed by welding sheet metal to the inner wall of the receiving barrel. The convex strips 111 can strengthen the receiving barrel 11. At the same time, when the battery carrier basket is placed in the receiving barrel 11, the padding of the convex strips 111 can avoid the contact area between the inner wall of the receiving barrel 11 and the battery carrier basket being too large, so as to avoid excessive friction, thereby preventing large-area friction between the inner wall of the receiving barrel 11 and the carrier basket. In the embodiment of the present invention, the number of the convex strips 111 is 6.

[0036] The electrolyte collection layer 110 is arranged at the bottom of the storage barrel 11, and is a fully enclosed design to prevent the electrolyte from being contaminated after dehydration. An isolation disc 112 and a storage barrel fixed disc 113 are arranged between the battery cell shelf layer and the electrolyte collection layer 110; the isolation disc 112 is roughly dome-shaped, so that there is a certain gap between the center of the isolation disc 112 and the center of the fixed disc 113, and when the storage barrel 11 rotates at high speed, it can play a shock-absorbing role for the battery cell carrier basket placed in the storage barrel 11; the radial direction of the isolation disc 112 and the vertical direction of the inner wall of the storage barrel 11 are less than 90°, and the edge of the isolation disc 112 is provided with a plurality of through holes 1120 that directly pass through the electrolyte collection layer 110, so as to facilitate the electrolyte to enter the electrolyte collection layer 110 from the through holes 1120. In the embodiment of the present invention, there are at least two through holes 1120. The isolation disc 112 is also provided with a plurality of reinforcing ribs 1121 along the radial direction.

One end of the reinforcing rib 1121 points to the center of the isolation disc 112, and the other end is connected to the convex strip 111 on the inner wall of the receiving barrel. In the embodiment of the present invention, the number of the reinforcing ribs 1121 is 6 corresponding to the number of convex strips 111, and the 6 reinforcing ribs 1121 divide the isolation disc into 6 equal fan blade blocks 1122. A flange 1123 is provided in the center of the isolation disc 112, and the isolation disc 112 is fixed by the central flange 1123 and a nut.

[0037] As another embodiment of the present invention, the reinforcing rib is an arc-shaped groove, and the plurality of arc-shaped grooves divide the disk surface into a plurality of blade blocks. The blade blocks are arranged obliquely between two arc-shaped grooves, and the ends of the arc-shaped grooves are connected to the through holes on the edge of the disk, so as to facilitate the electrolyte to flow directly into the electrolyte collection layer. After the dehydration is completed, the suction pipe of the vacuum suction mechanism is inserted into the electrolyte collection layer 110 through the through hole 1120 on the isolation disk 112, and the electrolyte in the electrolyte collection layer 110 is sucked into the suction mechanism for storage for reuse.

[0038] The fixed disk 113 is fixedly connected with the rotating shaft 4, and the rotating shaft 4 is connected to the driving motor 2 through the pulley 40. When the driving motor 2 is working, the rotating shaft 4 is driven to rotate, thereby driving the storage barrel 11 to rotate. During the high-speed operation of the storage barrel 11, the electrolyte on the surface of the battery cell in the carrier basket is separated from the battery cell under the action of centrifugal force, thereby achieving the purpose of de-liquidation of the battery cell. Of course, in other embodiments, the rotating shaft can also be connected to the driving motor 2 by means of gears.

[0039] The base 3 supporting the deliquidation body is provided with three support columns 30, a chassis 31 and a support plate 32 for fixing the deliquidation body 1; wherein, a space for accommodating the rotating shaft 4 and the pulley 40 is provided between the chassis 31 and the support plate 32, the distance between the chassis 31 and the ground is less than the distance between the chassis 31 and the support plate 32, and the chassis 31 is thicker than the support plate 32, which is conducive to the stability of the device and is not prone to shaking during rotation. The support column 30 is in the shape of a bullet head, wherein the lower half is a solid and the upper half is a hollow structure, and the support plate 32 is fixed by a nut 33 in the hollow structure, so as to facilitate shock absorption. The base is also provided with a rotating shaft brake device connected to the rotating shaft 4. After the driving motor stops, the rotating shaft can stop rotating through the rotating shaft brake device, thereby stopping the storage barrel from rotating. In an embodiment of the present invention, the motor adopts a variable frequency control motor.

[0040] The vacuum liquid suction mechanism includes a liquid storage barrel, a liquid extraction pipe, and a PU pipe connecting the liquid extraction pipe and the liquid storage barrel.

The liquid extraction pipe is made of stainless steel, one end of the PU pipe is connected to the interface pipe, and the other end is connected to the liquid extraction pipe in a pluggable manner. When the liquid extraction pipe is inserted into the electrolyte collection layer of the deliquidation column, the electrolyte in the electrolyte collection layer is sucked into the liquid storage barrel under air pressure by controlling the control valve on the interface pipe. The lower layer of the liquid storage barrel is used to hold the electrolyte, and the upper layer is a vacuum layer.

[0041] By means of the electrolytic capacitor dehydration device of the present invention, the electrolyte after dehydration enters the fully enclosed electrolyte collection layer 110 along the through hole 1120 on the edge of the isolation disc 112 of the receiving barrel 11, and then the electrolyte is directly sucked into the liquid storage barrel for storage through the vacuum suction mechanism.

The lower layer of the liquid storage barrel is used to hold the electrolyte, and the upper layer is a vacuum layer.

[0047] The electrolyte after dehydration enters the fully enclosed electrolyte collection layer along the through holes on the edge of the isolation disc of the receiving barrel, and then the electrolyte is directly sucked into the liquid storage barrel for storage through the vacuum liquid suction mechanism.
