Problems solved by technology

These drying methods all adopt intermittent operation, and need to be loaded one by one for drying, and the production efficiency is low; and the fusible fluorine-containing resin particles cannot directly absorb the heat of the heating source, the heating time is long, and the efficiency is low; During the drying and devolatilization process of permanent fluorine-containing resin, there is a problem of uneven heating caused by inability to turn over
These defects lead to low drying and devolatilization efficiency, high energy consumption, poor devolatilization effect, and intermittent operation is labor-intensive, the workplace environment is poor, and impurities such as dust are easily mixed.

Abstract

The invention discloses a device capable of quick removing meltable fluorine-containing resin volatile matters. The device comprises a box body (1), and is characterized in that the upper part in the box body (1) is provided with a feeding conveying belt (4), the lower part in the box body (1) is provided with a discharge conveying belt (5), and the upper parts of the feeding conveying belt (4) and the discharge conveying belt (5) are each provided with far infrared directional radiation heaters (2); the bottom of the box body (1) is provided with hot air inlet pipes (6), and the top of the box body (1) is provided with tail gas outlet pipes (7); the outer side of the front end of the feeding conveying belt (4) is provided with a transition plate (3), and the transition plate (3) is arranged above the discharge conveying belt (5) so that a meltable fluorine-containing resin on the feeding conveying belt (4) can overturn onto the discharge conveying belt (5) through the transition plate (3). The invention also provides a method adopting the device to quick remove the meltable fluorine-containing resin volatile matters. The device and the method have the advantages of convenient operation, high efficiency, safety, environmental protection, and good devolatilization effect.

Description

technical field [0001] The invention relates to a device for removing volatile matter of fusible fluorine-containing resin, in particular to a device and method for rapidly removing volatile matter of fusible fluorine-containing resin. Background technique [0002] Fusible fluorine-containing resins mainly refer to fluorine-containing plastics that can be formed by melt extrusion processing technology, mainly including polyperfluoroethylene propylene, polyvinylidene fluoride, vinylidene fluoride-chlorotrifluoroethylene copolymer, ethylene-tetrafluoroethylene Vinyl fluoride copolymers, ethylene-chlorotrifluoroethylene copolymers, etc., due to their excellent physical and chemical properties, such fluorine-containing resins are generally used as materials for wires and cables under special requirements, or made into films, plates, rods, and profiled materials and other products. The original state of fusible fluorine-containing resin is generally powder, which needs to be pro...
