Abstract

The invention discloses an energy-saving type synthetic leather drying device based on double bypass air blades. The energy-saving type synthetic leather drying device based on the double bypass air blades comprises a drying chamber, a plurality of double bypass air blades and a conveyor belt, each double bypass air blade is arranged on the upper part of the drying chamber respectively, the conveyor belt is fixed to the lower part of the drying chamber, two air inlets of the double bypass air blades are connected to an outer air supplying duct and a circular duct respectively, outlets of the double bypass air blades are connected to the circular duct through the drying chamber, and the synthetic leather is flatly paved on the conveyor belt to enter in or get out from the drying chamber. The energy-saving type synthetic leather drying device based on the double bypass air blades is based on the principle of double bypass air blades, negative pressure zones are formed on necking down parts of the outlets of inner bypasses through a small amount of hot air flowing in high-speed in the inner bypass, waste exhaust air coming from an outer bypass after adsorption and filtration is attracted and jointly acts on the surface of the synthetic leather, so that cyclic utilization of the hot air is realized, and the double energy-saving effect of using waste heat and lowering the power of amain draught fan is achieved, so that the production cost of the synthetic leather product is lowered.

Description

technical field [0001] The invention relates to an energy-saving drying equipment for synthetic leather based on a double-duct air knife. Background technique [0002] Synthetic leather is a material widely used for surface coverings such as furniture and vehicle interiors. Synthetic leather needs to be dried during processing to reduce the moisture content in the product for subsequent processing. Traditional synthetic leather drying devices generally use steam to heat the water inside the water tank to increase the surface temperature of the water tank, and then use a heat exchanger to blow the heat to the product through hot air to evaporate the water in the product. The drying devices widely used at present do not realize the repeated utilization of steam resources, and the energy waste is serious, which does not meet the current needs of energy conservation and environmental protection. Contents of the invention [0003] The purpose of the invention is to solve the ...
