Background
The current gravure printing is widely applied in the field of printing and packaging, particularly the appearance of water-based ink, so that the gravure printing is environment-friendly, no VOCs are discharged, and the application field of the gravure printing is further widened. However, the aqueous ink is not volatilized and dried as solvent ink, so that the speed of a unit gravure press of the general aqueous ink is generally low. The requirements on a hot air drying system are high, and the energy consumption is high. The heating power required by a hot air drying system of a unit is about 40KW, and the hot air drying system is a pain point for gravure of water-based ink. Currently, the advent of air-source heat pumps has resulted in significant savings in the electrical energy of hot air drying systems. By utilizing the compressor, the refrigerant realizes heat absorption and heat release through phase change, and the efficiency and economy of heating hot air are greatly improved.
The water-based ink gravure printing machine has one oven for each machine set, and is provided with a hot air drying system for providing hot air. Some manufacturers currently replace a hot air drying system with an air energy heat pump to supply hot air to an oven on a unit. The oven on the unit is generally provided with two pipelines connected with the air energy heat pump, one is an air inlet pipeline and the other is an air return pipeline. And hot air enters the gravure baking oven through the air inlet pipeline, evaporates and absorbs the ink moisture on the printing product, and then enters the air energy heat pump through the air return pipeline. At this time, the return air temperature is still high, and the direct discharge can cause heat energy waste.

Detailed Description
The utility model will be described in detail below with reference to the drawings and the detailed description.
Example 1
The utility model relates to an aerodynamic energy heat pump heat exchange system structure for water-based ink gravure printing, as shown in figure 1, wherein the whole heat exchanger consists of a standard heat exchanger body and other sheet metal parts, and four corners of the heat exchanger body 5 are wrapped by four supporting strips 3 like angle steel. The opposite sides of the support batten 3 are respectively provided with side sealing plates 4. The cross section of the front cavity 2 of the heat exchanger is provided with a round opening, the end part of the front cavity is welded with a cylinder, and the end part of the cylinder is the air inlet 1 of the return air heat exchanger.
Example 2
On the basis of the embodiment 1, as shown in fig. 2, the front and rear parts of the supporting lath 3 are provided with turned edges, the turned edges at the front ends of the supporting lath 3 are connected with the front cavity 2 of the heat exchanger through self-tapping screws 7, and the rear ends of the supporting lath 3 are connected with the rear cavity 8 of the heat exchanger through self-tapping screws 7 to form a whole. As shown in fig. 3, the rear end of the rear cavity 8 of the heat exchanger is provided with an air return heat exchanger air outlet 9, and the bottom of the rear cavity 8 of the heat exchanger is provided with a trapezoidal sheet metal boss 12.
Example 3
On the basis of the embodiment 2, a bevel side surface of the metal plate boss 12 is provided with a return air port 11, a pipe joint is welded at the bottom beside the metal plate boss, and a water outlet pipe 10 is arranged on the metal plate boss.
As shown in fig. 4, the connection between the structure of the heat exchange system of the aerodynamic energy heat pump for gravure printing of water-based ink and the air energy heat pump is as follows:
the air return heat exchanger air inlet 1 of the heat exchanger front cavity 2 is connected with an air return pipeline of a gravure printing unit oven, and air return of the printing ink dried in the oven enters the heat exchanger body 5 through the air return heat exchanger air inlet 1. The return air heat exchanger air outlet 9 on the rear cavity 8 of the rear heat exchanger is in butt joint with the return air fan air inlet 14 on the return air fan 16 in the air source heat pump. Above the heat exchanger is a fresh air heat exchanger air inlet 6 for accessing fresh air to be heated. The lower part is a fresh air heat exchanger air outlet 13 which is the position for the fresh air after heat exchange to flow out. The lower part is connected with a wind mixing cavity 17, and the lower part of the wind mixing cavity 17 is connected with a condenser 18 in the air energy heat pump.
The working principle of the aerodynamic energy heat pump heat exchange system structure for water-based ink gravure printing is that when in operation, the return air of the dried ink in the gravure baking oven enters into the front cavity 2 of the heat exchanger through the air inlet 1 of the return air heat exchanger of the developed heat exchanger. The front cavity 2 of the heat exchanger is communicated with the copper pipe opening in the heat exchanger body 5, so that return air enters the copper pipe. On the other hand, under the action of the negative pressure at the bottom of the fresh air to be subjected to heat exchange, the fresh air flows in from the air inlet 6 of the fresh air heat exchanger at the upper part, namely the gap between the copper pipes. Because the return air temperature is much higher than the fresh air temperature, the heat heats the fresh air through the copper pipe, and the heated fresh air flows into the air mixing cavity 17 through the fresh air heat exchanger air outlet 13.
Because the return air after heat exchange and temperature reduction is generally much higher than the fresh air after heat exchange, the return air continues to flow to the rear cavity 8 of the heat exchanger under the negative pressure effect generated by the return air fan 16. As the humidity in the return air from the oven is very high, water molecules in the water-based ink are absorbed, and the humidity saturation state is basically achieved. Such return air is cooled in the heat exchanger by heat exchange, and some of the water molecules therein are condensed to water, which is carried into the rear chamber 8 of the heat exchanger due to the return air flow direction. The water will flow to the bottom of the back chamber 8 of the heat exchanger, whereas the bottom of the back chamber 8 of the heat exchanger is provided with a water outlet pipe 10, through which water will flow to the outside of the machine under the influence of gravity.
Part of the return air which is still at high temperature after cooling enters the return air blower 16 through the return air blower air inlet 14 due to the action of the return air blower 16, and is pumped into the air outlet of the air energy heat pump through the return air blower air outlet 15. And the other part of the return air has a certain high temperature, and a part of water is removed due to temperature reduction, so that negative pressure caused by a lower fan of the main air path enters the air mixing cavity 17 through the air return port 11 on the side surface of the sheet metal boss 12 at the bottom of the rear cavity 8 of the heat exchanger and fresh air heated by the heat exchanger is mixed and enters the condenser 18 for heating. The temperature of the air entering the condenser 18 is greatly increased so that the heating power of the condenser can be saved. Therefore, the temperature in the return air is fully utilized, and the effect of effectively saving electric energy can be achieved.
The utility model can heat fresh air by the heat exchanger to achieve the effect of heat exchange by utilizing heat energy of return air, and can reuse a part of dehumidified return air, thereby greatly improving the basic temperature of the inlet air and having obvious energy-saving effect.
