Gas-catalytic, flameless and infrared-radiation hot air internal recycle drying unit module of passenger car

Abstract

The invention discloses a gas-catalytic, flameless and infrared-radiation hot air internal recycle drying unit module of a passenger car, and relates to a drying device for quickly drying putty and a film on the surface of the passenger car. The gas-catalytic, flameless and infrared-radiation hot air internal recycle drying unit module comprises a fixed bracket, wherein a hot air internal recycle system and at least one gas-catalytic, flameless and infrared-radiation heater are arranged in the fixed bracket; the hot air internal recycle system comprises an air feeding system and an air return system which are communicated with each other; the air feeding system is provided with a flow-equalizing air feeding plate below each gas-catalytic, flameless and infrared-radiation heater; and the gas-catalytic, flameless and infrared-radiation heater is connected to a gas source through a gas inlet tube. In use, even a circulating fan of the hot air internal recycle system on one drying unit module has faults, the circulating fans of the rest of drying unit modules still can operate without affecting drying progress of a product. The gas-catalytic, flameless and infrared-radiation hot air internal recycle drying unit module is uniform in heating, capable of avoiding generating chromatic aberration during product drying, has characteristics of being high in heating efficiency, low in cost, environmentally-friendly, safe and reliable, and the like, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a drying device for quickly drying putty and paint film on the surface of a passenger car, in particular to a gas catalytic flameless infrared radiation hot air internal circulation drying unit module for a passenger car. Background technique [0002] In the production process of passenger cars such as passenger cars and sedans, the quality of surface coating has been paid more and more attention. However, the existing large-scale drying equipment for passenger cars is generally of integral structure, and only a If the circulating fan fails, the entire drying equipment will not work, which seriously affects the production progress of passenger cars. In addition, the heaters of the existing large-scale drying equipment for passenger cars are mainly electric heating and fuel gas heating. The cost of electric heating is high, the thermal efficiency is low, and fuel gas heating is unsafe; Color difference occurs on the surface whe...
