[0033] Compared with the prior art, the above one or more technical solutions in the polyethylene particle mixing dehumidification device provided in the embodiment of the utility model have at least one of the following technical effects:

[0034] The dehumidification chamber 11 is divided into an upper loading chamber 13 and a lower air storage chamber 14 by a loading plate 12; the polyethylene particles pass through a feed channel 131 into the upper loading chamber 13 for dehumidification, and are discharged from a discharge channel 132; when in use, the stirring blade 23 rotates to stir the polyethylene particles, and because the bottom of the stirring blade 23 contacts the top of the loading plate 12, the polyethylene particles on the top surface of the loading plate can also be stirred; at this time, the wind generated by the air supply device 3 enters the air storage chamber 14, and then passes through the ventilation holes 121 into the gaps between the polyethylene particles, thereby air-drying the polyethylene particles; the utility model makes it easier for wind to enter the gaps between the polyethylene particles through the mutual cooperation of the loading plate 12, the air supply device 3, and the stirring device 2, thereby increasing the evaporation rate of water on the surface of the polyethylene particles, so as to improve the dehumidification efficiency and produce a better dehumidification effect.

[0035] In one embodiment of the present invention, reference Figure 2 The carrier plate 12 is tilted in the dehumidification chamber 11; the feed port of the discharge channel 132 is close to the lower end of the carrier plate 12; the inclination angle of the carrier plate relative to the horizontal plane is greater than 15° and less than 30°, so that the polyethylene particles on the top surface of the carrier plate 12 can automatically slide to the feed port of the discharge channel 132 on the carrier plate under the action of gravity; the feed port is provided with a valve to control its opening or closing, and the valve can be set as an electric valve or a manual valve, and the specific structure is set according to actual needs; of course, in other embodiments, the carrier plate 12 can be set horizontally so that the pressure of the polyethylene particles on the carrier plate 12 is uniform, so as to improve the load-bearing stability of the carrier plate 12.

[0037] Specifically, refer to Figure 3 The connecting assembly 24 includes a fixing member 241 and an elastic member 242; the fixing member 241 is arranged on the stirring shaft 22 and is located above the stirring blade 23, one end of the elastic member 242 is connected to the fixing member 241, and the other end of the elastic member 242 is connected to the stirring blade 23; the elastic member 242 is preferably set as a straight spring, and the two free ends of the elastic member 242 are always in contact with the fixing member 241 and the stirring blade 23, so that when the stirring blade 23 is in a low position, it can still be in contact with the top surface of the loading plate 12 under the elastic force of the elastic member 242; a limiting structure is also connected between the stirring shaft 22 and the stirring blade 23 to improve the connection stability between the two, so that the elastic member 242 is only used to provide elastic pressure to the stirring blade 23, and is not used to counteract the torsion formed relative to the stirring shaft 22 when the stirring blade 23 stirs the polyethylene particles.
