Description

Technical Field

[0002] With the rapid development of consumer electronics, aluminum electrolytic capacitors have steadily grown in this sector. Their application has also expanded, driven by structural transformation and technological advancement, into emerging fields such as energy-saving lamps, inverters, and new energy sources, extending their reach. Aluminum electrolytic capacitors' fundamental functions in electronic circuits can be summarized as: passing AC and blocking DC, providing filtering, bypassing, coupling, and rapid charge and discharge capabilities. They are also characterized by their compact size, high capacity storage, and high cost-performance. With the advancement of modern technology and the continuous improvement of capacitor performance, electrolytic capacitors have found widespread application in consumer electronics, communications products, computers and peripherals, new energy, automation control, the automotive industry, optoelectronics, high-speed rail, aviation, and military equipment.

[0003] During the preparation process of aluminum electrolytic capacitors, electrolyte is injected into the inside. In order to ensure the performance and quality of the battery, the composition and proportion of the electrolyte need to be strictly controlled.

The cold air then enters the exhaust pipe 10 through the second air guide pipe 19 and the second air delivery pipe 21, and is then discharged through the outlet pipe 11, so that the cold air cools the outside of the mixing tank 1, thereby cooling the electrolyte from the outside to the inside. When the cold air enters the second air guide pipe 19, it is diverted and enters the interior of the installation box 20. The adsorbent 30 inside the installation box 20 adsorbs moisture carried in the cold air. The dried cold air enters the interior of the connecting pipe 14 through the first air delivery pipe 15. It is then transported to the inside of the stirring rod 22 through the refrigeration pipe 26, and then discharged through the exhaust holes 23 and the exhaust nozzle 28 provided on the stirring rod 22, thereby cooling the electrolyte in the mixing tank 1 from the inside to the outside, and the gas blown upward through the air supply pipe 15 is diverted by the upper air guide pipe 13, and enters the inside of the feed pipe 5 through the air guide pipe 13, thereby accelerating the raw materials input through the feed pipe 5, and cleaning the raw materials remaining on the screw conveyor 46 inside the feed pipe 5.

The cold air is then discharged through the exhaust hole 23 and the exhaust nozzle 28 provided on the stirring rod 22 , thereby cooling the electrolyte in the mixing tank 1 from the inside out. The gas blown upward through the gas delivery pipe 15 is diverted by the upper gas guide pipe 13 and enters the interior of the feed pipe 5 through the gas guide pipe 13, thereby accelerating the raw materials fed through the feed pipe 5; Step 4: The mixed and cooled electrolyte is discharged through the drain pipe 3 provided below.

[0038] According to the proportioning method, through the setting of the adsorbent 30, cold air enters the interior of the adsorbent 30 through the diversion of the air guide pipe 19, the adsorbent 30 adsorbs the moisture carried by the cold air and dries the cold air. The dried cold air enters the interior of the refrigeration pipe 26 through the air supply pipe and the connecting pipe 14, and is then transported to the interior of the stirring rod 22 through the refrigeration pipe 26, and is discharged through the exhaust hole 23 and the exhaust nozzle 28 provided on the stirring rod 22, thereby quickly cooling the proportioned liquid inside the mixing tank 1 to prevent the electrolyte from being corroded by moisture in the air.
