In order to achieve the above object, the utility model adopts the following technical solutions:

A drying device convenient for energy saving and emission reduction, comprising an oven 1, a heating box 2, and a heat exchanger 3, the heating box 2 is provided with a heater, and the air outlet of the oven 1 passes through a return air pipe 41 to all The heating box 2 returns air, and the heating box 2 is connected with a fan 5 for extracting the gas in the heating box 2. The output end of the fan 5 enters the air into the oven 1 through the air inlet pipe 42, and the heat exchange A fresh air inlet 31 is provided on the device 3, and a fresh air conveying pipe 32 for sending the wind entering the heat exchanger 3 from the fresh air inlet 31 to the heating box 2 is respectively connected, and is used to transfer the returned air to the heat exchanger 3. The air part in the air duct 41 is sent to the first exhaust connecting pipe 33 of the heat exchanger 3, and the second exhaust connecting pipe 34 for outputting the wind that enters the heat exchanger 3 through the first exhaust connecting pipe 33 .

As mentioned above, a drying device that facilitates energy saving and emission reduction, the fresh air inlet 31 is connected with a fresh air inlet pipe 311 .

Compared with the prior art, the beneficial effects of the utility model are:

In this case, the outlet of the oven, the air return pipe, the heating box, the fan, and the air inlet of the oven are connected in sequence to form a loop, which is convenient for the recycling of old air and increasing its temperature according to needs, which is conducive to energy saving and emission reduction, and has substantial characteristics and progress; In addition, the first air exhaust connecting pipe in this case is used to send the air part in the return air pipe to the heat exchanger and then discharge through the second exhaust air connecting pipe, and the fresh air entering from the fresh air inlet passes through the heat exchanger , The fresh air transmission pipe is sent to the heating box. In this way, it is beneficial to discharge part of the old air in the device to reduce the concentration of harmful gases and to add a part of fresh air to the device to reduce the concentration of harmful gases. In this process, The exhausted old air is exchanged and preheated by the heat exchanger for the incoming fresh air, which is beneficial to heat recovery and realizes energy-saving control, which has substantial characteristics and progress; in addition, the fresh air transmission pipe in this case is connected to the heating box instead of It is directly connected to the oven, which can avoid the problem that the wind with insufficient temperature directly enters the oven and affects the drying effect.

Detailed ways

The utility model feature and other relevant features are described in further detail below through the embodiments, so as to facilitate the understanding of those skilled in the art:

As shown in Figures 1 to 2, a drying device that is convenient for energy saving and emission reduction includes an oven 1, a heating box 2, and a heat exchanger 3, the heating box 2 is provided with a heater, and the oven 1 The air outlet returns air to the heating box 2 through the air return pipe 41, and the heating box 2 is connected with a fan 5 for extracting gas from the heating box 2, and the output end of the fan 5 flows to the heating box 2 through the air inlet pipe 42. The oven 1 is air-intake, and the heat exchanger 3 is provided with a fresh air inlet 31, and is respectively connected with a fresh air transmission for sending the wind entering the heat exchanger 3 from the fresh air inlet 31 to the heating box 2. Pipe 32, the first exhaust connecting pipe 33 for sending the wind in the return air pipe 41 to the heat exchanger 3, and the wind that enters the heat exchanger 3 through the first exhaust connecting pipe 33. The output second exhaust connecting pipe 34.
