[0002] The outstanding features of thermoplastic polyurethane elastomers are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. In a humid environment, the hydrolysis stability of polyether esters is far greater than that of polyesters, and they need to be dehydrated during production.

[0003] However, in actual use, the dehydration method of the dehydration device is usually relatively single, which easily leads to low dehydration efficiency. Moreover, when the dehydration process is large, the dehydration effects of different material positions will be different, some fast and some slow, and the overall dehydration efficiency of the material will also be affected. Therefore, a device that can combine multiple dehydration methods is needed to improve efficiency. At the same time, it also needs to be able to stir the material well to maintain uniform dehydration. Utility Model Content

A rotating motor is fixedly connected to the bottom of the tank body, and the top power output end of the rotating motor passes through the interior of the tank body and is fixed to the bottom of the filter cartridge.

[0010] Preferably, the spacings between the plurality of stirring plates and the central rod inside the filter cartridge are different, the outer wall of the central rod and the fixing ring are fixedly connected to each other, and the side walls of the inclined plates are inclined.
