Description

Technical Field

[0001] The invention belongs to the technical field of drying equipment, and specifically refers to multifunctional drying equipment for waste heat recovery and reuse. Background Art

[0002] Backing dry refers to the process of removing solvents and retaining solid content in some way. It usually refers to the process of introducing hot air to evaporate and take away the moisture in the material. According to the three ways of heat transfer, heat conduction, heat convection, and heat radiation, there are also three corresponding ways of drying: drum drying, hot air drying, and far-infrared drying. The main function of drying equipment is to vaporize and release the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain solid materials with specified moisture content. Drying operations are widely used in many industrial production and daily life scenes.

[0003] However, when traditional drying equipment is in operation, there are significant defects in the dehumidification process. While discharging moisture, a large amount of heat energy is also taken out of the equipment, which not only causes serious waste of energy, but also makes the drying cost high.

The outer wall of the material drying chamber 2 is fixed with a card slot 4, and a card handle 5 is fixed with the card slot 4 corresponding to the card slot 4 on the door panel 3. The handle 5 is clamped in the inside of the card slot 4. A top bin 6 is provided on the top of the main body box 1, a dehumidification component 7 is provided in the top bin 6, and a waste heat recovery component 8 is also provided in the top bin 6.

It also includes universal wheels 19, and the universal wheels 19 are evenly fixed to the bottom of the main body box 1.

[0029] like Figure 1-8 As shown, the dehumidification component 7 includes a dehumidification fan 11, which is arranged through the top of the material drying chamber 2 and two groups are arranged corresponding to the two groups of material drying chambers 2 respectively. The two groups of dehumidification fans 11 are connected to extend the air duct 12.

[0030] like Figure 1-8 As shown, the waste heat recovery component 8 includes a heat exchanger 13, which is fixedly connected to the top of the main box 1, and the two groups of air ducts 12 are connected to the heat exchanger 13. The waste heat recovery component 8 also includes a fresh air fan 14, which is fixedly connected to the top of the main box 1 and connected to the heat exchanger 13. A heat exchange fresh air inlet 24 is also provided on the top of the main box 1, and the heat exchange fresh air fan inlet 24 is connected to the heat exchanger 13. The waste heat recovery component 8 also includes a dehumidification port 16, which is arranged on the front side wall of the top bin 6 and corresponds to the dehumidification outlet of the heat exchanger 13. A placement bin 25 is provided inside the center of the front of the main box 1, and a circulating fan 22 is provided in the placement bin 25 and the circulating fan 22 is located directly above the heating chamber 10. The circulating fan 22 is connected to the heat exchange fresh air inlet 24, and the circulating fan 22 is connected to the heating chamber 10. The side of the heating chamber 10 is symmetrically provided with a conduit 23, and the heating chamber 10 is connected to the two groups of material drying chambers 2 through the conduit 23.

[0031] like Figure 1-8 As shown, the intelligent control component 9 includes a PLC control module 18, which is arranged at the center of the main box 1. The material drying chamber 2 is also provided with a temperature sensor 20 and a humidity sensor 21. The dehumidification fan 11, the heat exchanger 13, the fresh air fan 14, the temperature sensor 20, the humidity sensor 21, the circulation fan 22 and the PLC control module 18 are electrically connected.

[0032] When in use, first install the material drying chamber 2, dehumidification fan 11, heat exchanger 13, and fresh air fan 14 according to the design requirements, and connect the pipelines. After the power is turned on, start the PLC control module 18 to initialize the equipment, including setting the default drying mode, the initial operating parameters of each component, etc.;

[0033] Put the material to be dried into the material drying chamber 2, and select the appropriate drying mode in the interface of the PLC control module 18 according to the material type.

Finally, the hot air enters the material drying chamber 2 through the conduit 23 to complete the cycle. During the drying process, the PLC control module 18 adjusts the operating parameters of each component in real time according to the data fed back by the sensor to ensure the efficient and stable progress of the drying process;

[0034] When the material reaches the preset drying degree, the PLC control module 18 issues a command to turn off the dehumidification fan 11, the fresh air fan 14 and the heating device and other equipment to complete the drying operation;

[0035] In summary, this device can realize waste heat recovery and reuse by combining the dehumidification component 7, the waste heat recovery component 8 and the intelligent control component 9, which greatly reduces energy consumption and reduces drying costs. According to tests, compared with traditional drying equipment, the energy utilization rate can be increased by more than 25%, reducing the thermal pollution caused by direct heat energy discharge to the environment, meeting environmental protection requirements and correspondingly regulating by setting the PLC control module 18, which can adapt to the drying needs of various materials and improve the versatility and practicality of the equipment.
