Problems solved by technology

[0002]Currently, bolted aluminum electrolytic capacitors use vacuum or compressed air to pressurize the core package into the electrolyte pot, and then vacuumize or pressurize the air Place it in the state for more than 30~40 hours, and manually monitor and observe whether it is soaked in the middle process. For the core bag above Φ50, the time is longer, and the pot body must be opened many times in the middle process, which is very inconvenient to operate. The diameter of the bolt type aluminum electrolytic capacitor is ≥ Φ70, and the length ≥150mm core package and slender aluminum electrolytic capacitors have a diameter of Φ10 and a core package length ≥50mm. The middle part is likely to cause insufficient adsorption of electrolyte. After impregnation, the capacity of the capacitor will decrease and the loss will be large. , it is necessary to add a considerable number of impregnation pots, compressed air production needs to be equipped with air compressors, refrigerators, dryers, and oil-water separator equipment to process the gas and transfer it to a large storage tank through pipes, and then send the gas to to the impregnation pot, and the pressure loss during the transmission process is large, the operation is inconvenient, the equipment occupies a large area and space, and the investment, manufacturing and maintenance costs are high. At the same time, the air compressor is noisy and oily, and the energy consumption is large. Thorough treatment will cause certain pollution to the electrolyte and directly affect product quality

Abstract

The invention discloses a full-automatic electrolyte pressurizing impregnation device and method for an aluminum electrolytic capacitor. The device comprises am impregnation core bag pot, an electrolyte storage pot and a pressure pump, wherein the impregnation core bag pot and the electrolyte storage pot are connected with a secondary fluid pump through the pressure pump, the impregnation core bag pot is provided with a pressure gage, the upper end of the pressure pump is provided with a transducer, the upper end of the secondary fluid pump is provided with a pressure pump variable-frequency governor, the upper end of the pressure pump variable-frequency governor is provided with a controller, and the upper end of the controller is provided with an alarm lamp. When a capacitor core bag is impregnated, the method that self electrolyte is pressurized and permeated into the core bag is adopted. The device has small volume, saves occupied space, and lowers cost in equipment input and manufacture; and the method has the advantages of being low in impregnation temperature, more energy-saving and high in work efficiency, preventing impurities such as water and oil from polluting the electrolyte, and guaranteeing the electrical property stability and reliability of the aluminum electrolytic capacitor.

Description

Technical field: [0001] The invention discloses a crawler electrolytic capacitor manufacturing and processing equipment and process, in particular an aluminum electrolytic capacitor equipment and process, especially a bolt-type and slender aluminum electrolytic capacitor equipment and process. Background technique: [0002] At present, bolt-type aluminum electrolytic capacitors use vacuum or compressed air to pressurize the core package into the electrolyte pot, and place it in a vacuum or air pressurized state for more than 30 to 40 hours. Soaking, it takes longer for the core package above Φ50, and the pot body must be opened several times in the middle process, which is very inconvenient to operate. The diameter of the bolt type aluminum electrolytic capacitor is ≥ Φ70, and the core package and the slender aluminum electrolytic capacitor with a length of ≥ 150mm have a diameter of Φ10. The core package with a length of ≥50mm, the middle part is likely to cause insuffici...
