Description

Technical Field

[0001] The utility model relates to the technical field of coating film processing, in particular to a PE coating film processing and drying device. Background Art

[0002] PE coating film is made by applying para-aramid slurry by blade coating, where the full name of para-aramid is poly(p-phenylene terephthalamide) (PPTA), also known as aramid 1414. The poly(p-phenylene terephthalamide) molecule is a rigid structure, and aramid fiber has high strength, high modulus, and excellent heat resistance, flame retardancy, and chemical corrosion resistance. It is a key basic material, and the fibers prepared from it are usually used in many fields such as optical cable communications, composite materials, aerospace, national defense, and automobiles.

[0003] At present, poly(p-phenylene terephthalamide) film is prepared based on the low-temperature solution polymerization method, and the PE coating film is prepared through polymerization, swelling, dispersion, filtration and drying steps.

[0004] In the above process of drying the PE coated film, the steam evaporated during the drying of the PE coated film contains water and aluminum oxide, so the steam needs to be filtered and separated. In the prior art, for the filtration and separation of steam, the steam first needs to be cooled and liquefied, and then the aqueous solution containing aluminum oxide is filtered through a filter medium (such as filter paper or filter cloth) so that the aluminum oxide particles are retained on the filter medium, and the water flows out through the filter medium. Subsequently, the aluminum oxide on the filter medium can be cleaned to achieve separation from water, but in the prior art, when the filter medium intercepts the aluminum oxide in the steam, the large amount of aluminum oxide accumulated on the filter medium causes the filter device to be blocked, reducing the efficiency of the filtration, thereby requiring manual disassembly and cleaning on a regular basis, and it is impossible to clean it all at once, which increases the trouble of use. Utility Model Content

The temperature generated by the heating of the electric heating racks 3 is transferred to the coating film to dry the coating film. The steam generated by the drying contains water and aluminum oxide. At the same time, the exhaust fan 4 is started, and the exhaust fan 4 discharges the steam from the inside of the drying box 1 to the condenser 5. The steam is condensed and liquefied by the condenser 5. After condensation and liquefaction, the steam enters the filter cartridge 702 through the rotary joint 704 and the hollow shaft 703 for filtration and separation, and the water and aluminum oxide are separated. At the same time, the driving motor 7 is started, and the driving motor 7 drives the filter cartridge 702 to rotate through the annular rack 701. The rotation of the filter cartridge 702 enables the inner wall to fully contact with water and aluminum oxide, thereby increasing the contact filtration area, avoiding the accumulation of aluminum oxide at one position of the filter cartridge 702, and affecting the filtration of water from the filter cartridge 702, thereby improving the filtration efficiency.
