Pet silicone oil film recycling device and method for producing molten carbonate fuel cell diaphragm

Abstract

The invention discloses a pet silicone oil film recycling device for producing a molten carbonate fuel cell diaphragm. The pet silicone oil film recycling device comprises a conveying frame, wherein the conveying frame is provided with a driving roller and a driven roller which are spaced apart from each other and are connected through a belt; a placing box for holding diaphragm paste, a heating and drying device, a cooling device, a cleaning preheating device, a cleaning device and an oil brushing device are successively disposed on the top of the belt in the conveying direction; and the conveying frame is provided with a switch panel for controlling the heating and drying device, the cooling device, the cleaning preheating device, the cleaning device and the oil brushing device. By meansof the cleaning device and the cooperation of the cleaning device and a cleaning roller through an ultrasonic generator, the pet silicone oil film recycling device can remove the unformed paste and impurities on a pet silicone oil film. A fifth electric telescopic rod moves an oiling cylinder by means of the automatic oil brushing device, thus, the silicone oil can be evenly applied to the surface of the pet silicone oil film to achieve automatic cleaning and uniform oil brushing.

Description

Technical field [0001] The invention belongs to the technical field of battery diaphragm processing, and particularly relates to a pet silicon oil film recovery and reuse device for producing molten carbonate fuel cell diaphragms. Background technique [0002] As a chemical device that directly converts chemical energy into electrical energy, fuel cell has the advantages of high efficiency, zero emission, and no noise. The production and preparation of molten carbonate fuel cell membrane adopts the casting method, and the process is The pet silicone oil film driven by the casting roller is heated and formed to prepare a cured diaphragm material. [0003] During the preparation process, due to the dust in the air and the unformed diaphragm slurry adhering to the silicone oil film, the silicone oil film cannot be reused, and the recycling rate is low. The current cleaning method used is manual cleaning or through cleaning. A cleaning cloth is added to the roller, and the surface of ...

AI Technical Summary

Problems solved by technology

[0003] During the preparation process, due to the adhesion of dust in the air and unformed diaphragm slurry to the silicone oil film, the silicone oil film cannot be used again, and the recycling rate is low. The cleaning method currently used is manual cleaning or cleaning A cleaning cloth is added to the roller, and the surface of the silicone oil film is cleaned as the roller rotates

Both manual cleaning and automatic cleaning of the equipment destroy the silicone oil on the surface of the pet silicone oil film. After a long-term use of the pet silicone oil film, the silicone oil on the surface gradually decreases, resulting in poor formability of the re-cast diaphragm, which cannot be used again, and manual oiling will appear. Unevenness and safety hazards, etc.
