Copper coated steel wire hot air circulation drying system

Abstract

The invention discloses a copper coated steel wire hot air circulation drying system. After being heated and pressurized through an automatic temperature control hot draught fan, circulation drying air is led into a cyclone airflow drying cylinder inner cavity though a hot air duct and a tangent spiral air inlet and is exhausted through an inclined tee joint air outlet in the wire inlet ends, saturated steam formed through evaporation of a water film on the surface of a wire is taken away, and after water mist is adsorbed through a rotating filter screen device and a drying pipe adsorbs water again, the circulating drying air is fed to the automatic temperature control hot draught fan through an air returning duct to be heated and pressurized cyclically. A heat-preserving layer is arranged outside a cyclone airflow drying cylinder, and the inner cavity is provided with a turbulent flow drying segment. A low-pressure evaporation and separation segment is further provided with a drain valve. Moisture evaporation windows are distributed on the cylinder wall. A water film drive-way segment is arranged on the surface of the metal wire. According to the rotating adsorbing net device, a filter screen disk on a rotating shaft is driven by driving fan blades to rotate at high speed, and water mist is thrown to a reducing pipe shell in a centrifuging mode after being adsorbed by the filter screen disk. The rotating filter screen disk is composed of a plurality of layers of screen nets formed by interweaving fiber wires or metal and plastic monofilaments. A drying pipe is a heat-resistant and high-air-resistance pipe.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a copper-coated steel wire drying system. Background technique [0002] At present, the continuous electroplating of steel wires requires closed treatment, water washing, and drying processes; steel wire pickling lines, galvanized wires, enameled wires, and color-coated wires produced by steel wire manufacturers generally also need to be dried with hot air dryers, while other There are some deficiencies in drying method for metal wire drying. Generally, the fan for drying draws air at a room temperature of about 20°C into the air heater and heats it to 150-180°C. The heated air transfers heat to the metal wire while spraying on the surface of the wet metal wire, and takes away the moisture on the surface of the metal wire. Water vapor, thereby drying the wet metal wire. After the hot air dries the surface of the metal wire, all or a small part of the exhaust is supplemented by a...

Problems solved by technology

A condensing device is added to the hot air circulation system. Although the water mist is condensed into liquid water and discharged, the circulating air components are also cooled at the same time, which increases energy consumption; the discharged part of the high-humidity and high-temperature hot gas supplements the low-humidity cold air, and there is also a supplementary part At the same time of low-humidity cold air, dust and other harmful substances in the air are introduced into the hot air circulation drying system; in the high-humidity air environment, the drying quality cannot be guaranteed
