[0027] The following is combined with Figure 1 ~Attached Figure 4 The embodiments of the present utility model are described in detail.
[0028] The embodiment of the utility model provides a dewatering device. The dewatering device includes: a filter mechanism 1 and an adsorption mechanism 2.

The filter channel 3 is provided with a first inlet and a first outlet connected to the drying box, and valves are respectively adapted. A drain port is provided at the bottom of the drainage chamber 4, and a valve is adapted. The adsorption mechanism 2 includes: an adsorption channel 6, activated carbon arranged in the adsorption channel 6, and a third electric heating element arranged in the adsorption channel 6; it should be understood that the third electric heating element is usually configured as an electric heating wire or an electric heating network extending along the length direction of the adsorption channel 6. The adsorption channel 6 is provided with a second inlet 7 and a second outlet 8 connected to the drying box, and valves are respectively adapted; the adsorption channel 6 is also provided with an exhaust port 9, and a valve is adapted.

When the airflow carrying water vapor passes through the filter channel 3, the filter channel 3 will retain the water vapor in the airflow through the obstruction and adhesion of the filler, and the retained water vapor will flow to the drainage chamber 4 connected to the bottom of the filter channel 3. During deep drying, the valves of the first inlet and the first outlet are closed, and the valves of the drainage port, the second inlet 7, and the second outlet 8 are opened to discharge the accumulated water in the drainage chamber 4; and the adsorption channel 6 is in a connected state with the housing 5 of the drying box, thereby, in cooperation with the fan in the housing 5, a circulating airflow is formed between the adsorption channel 6 and the housing 5. When the airflow passes through the adsorption channel 6, the water vapor it carries will be adsorbed by the activated carbon. Finally, the valves of the second inlet 7 and the second outlet 8 are closed, and the valve of the exhaust port 9 is opened, and the water vapor adsorbed by the activated carbon is discharged by heating through the third electric heating element. The dehydration device uses the filter channel 3 to remove most of the water vapor in the airflow in the early stage to complete the preliminary drying; and uses the adsorption channel 6 to remove the remaining small part of the water vapor in the airflow in the later stage to complete the deep drying. Compared with removing water vapor by condensation, the dehydration device can greatly reduce the heat loss of the circulating airflow, which is conducive to reducing the energy consumption of the drying box.
