Cleaning and drying device for corrosion foil

Abstract

The invention discloses a cleaning and drying device for corrosion foil. The device comprises a box. An acid gas treatment device and a hot air device are fixedly connected to the top of the box, theacid gas treatment device communicates with an inner cavity of the box through an air outlet pipe, and a hot air pipe is horizontally arranged on the top of the inner cavity of the box. The two ends of the hot air pipe are closed, the bottom of the hot air pipe is provided with multiple air jets with screening holes, and the upper end of the hot air pipe communicates with the hot air device through a pipe. A cleaning device is arranged on the portion, below the hot air pipe, of the inner cavity of the box, a cleaning plate is arranged below the cleaning device, and a rotation shaft is arrangedbelow the cleaning plate. The cleaning plate is rotatably connected with the rotation shaft, and the bottom of the box is provided with a heater. After cleaning is completed, the heater is opened forheating and drying, the hot air device is started at the same time, hot air of the inner cavity of the box blows into the acid gas treatment device through the air outlet pipe, the acid gas treatmentdevice absorbs acid gas in the hot air, and the situation is avoided that since the environmental pollution is caused by the acid gas, the health of personnel is influenced.

Description

technical field [0001] The invention relates to the field of corroded foil production, in particular to a corroded foil cleaning and drying device. Background technique [0002] Medium and high voltage corroded foil for aluminum electrolytic capacitors is a special material for electronics. It is one of the basic industries and a weak link in China's electronics industry. It has been included in the national key development and support industry. Imported key materials for basic industries, because China’s production of corrosion foil materials for aluminum electrolytic capacitors starts late and develops slowly, domestic products mainly rely on imports, and the current domestic supply is in short supply. The speed is increasing, so the production of medium and high pressure corroded foil products has broad market prospects. [0003] The aluminum foil used in electrolytic capacitors belongs to the category of electronic aluminum foil. This is a corrosive material that works ...

Problems solved by technology

[0003] The aluminum foil used in electrolytic capacitors belongs to the category of electronic aluminum foil. This is a corrosive material that works under polar conditions. Electronic aluminum foils of different polarities require different corrosion types. The foil is corroded in a spongy manner, and the anode foil in the medium-voltage section is corroded in a moth-eaten manner. Before the 1980s, most electrolytic capacitors used manual chemical corrosion. After the 1980s, linked electrochemical corrosion was used, and the purity of the aluminum foil used for manual corrosion was low. (99.3% ~ 99.7%), and the requirements for the processing quality of aluminum foil are not high. At present, the existing corrosion foil cleaning device is inconvenient to operate. big damage
