Embodiment Construction

[0025] The invention provides an air heat recovery device for printing equipment, which includes a frame body 1; the inside of the frame body is divided into upper and lower cavities. There is a condensing heat exchanger 2 under the inside of the frame body, and a fan 5 installed on one side of the condensing heat exchanger to form a negative pressure. After negative pressure is formed at one end of the condensing heat exchanger 2, fresh air will be driven to be introduced from the fresh air outlet 3 And after being heated by the condensing heat exchanger, it is transported from the hot air pipe 4 to the fan inside the printing equipment that needs to be heated. The condensing heat exchanger can heat the fresh air, driven by the blower fan 5, it enters into other equipment that needs to heat the gas. A laminar flow pipe 18 is arranged in the hot air pipe 4, and a plurality of cylindrical laminar flow channels 20 are arranged in the laminar flow pipe. The value range of the rad...

Abstract

The invention discloses an air heat energy recovery device for printing equipment. The air heat energy recovery device for the printing equipment comprises a framework body, a draught fan, a drive motor, an exhaust duct, a heat exchanger, a compressor and an expander, wherein the draught fan is arranged inside the framework body and provided with the drive motor; the exhaust duct is arranged on the upper portion inside the framework body and used for leading out and discharging return air of the printing equipment; the heat exchanger is arranged on the exhaust duct and used for absorbing the heat of hot air inside the exhaust duct; and the compressor and the expander are arranged on the heat exchanger and a condensing heat exchanger and used for exchanging heat of the heat exchanger and heat of the condensing heat exchanger. According to the air heat energy recovery device for the printing equipment, the condensing heat exchanger can be used in cooperation with the heat exchanger, the temperature in the return air can be reutilized, the air heat energy is used, and therefore, the consumption can be reduced, and the energy utilization efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of drying auxiliary equipment for printing equipment, in particular to an air heat recovery device for printing equipment. Background technique [0002] In the printing industry or the soft packaging industry, it is often necessary to dry or heat the product. For example, in the soft package industry, high-heat air is usually used for drying. During the drying process, the hot air takes away the moisture and discharges it from the air outlet. Existing soft bag air heating devices mostly use fresh air to pass through the heating plate and heat it into high-temperature gas, then transport it to the corresponding drying part of the soft bag through pipelines, and discharge it directly into the air after drying. The method adopted in the prior art has a low heat utilization rate, generally only between 10% and 30%, and a large amount of heat is directly discharged into the air, resulting in waste of energy.
