Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-Figure 3 The utility model discloses a semi-conductive PE sheath material dehumidification device, comprising a storage tank 1 and a top cover 2, the top cover 2 is installed on the top surface of the storage tank 1, a bracket 3 is installed on the outer surface of the storage tank 1, a vacuum pump 4 is installed on the top surface of the top cover 2, a heating plate 5 is installed on the bottom surface of the top cover 2, a guide pipe 6 is installed on the bottom surface of the storage tank 1, a bearing 7 is installed on the bottom surface of the guide pipe 6, a stirring component is installed on the inner wall of the bearing 7, and a control component is installed on the inner wall of the guide pipe 6.

[0023] The top cover 2 is movably and rotatably connected to the storage tank 1, one side surface of the top cover 2 is in movably contact with the top surface of the storage tank 1, one end of the vacuum pump 4 extends from the top surface of the top cover 2 to its bottom surface, and the outer surface of the bearing 7 is fixedly connected to the inner wall of the outlet pipe 6.

[0024] The stirring assembly includes a driving motor 8, a reducer 9 is installed on the top surface of the driving motor 8, a stirring rod 10 is installed on the top surface of the reducer 9, a turning plate 11 is installed on the outer surface of the stirring rod 10, and the driving motor 8 is installed on the top surface of the inner wall of the bracket 3.

[0025] The reducer 9 is connected to the output end of the driving motor 8 , one end of the stirring rod 10 is fixedly connected to the output end of the reducer 9 , the stirring rod 10 is fixedly connected to the turning plate 11 , and the stirring rod 10 is spiral.

[0026] When the driving motor 8 is started, the reducer 9 connected to its output end will be driven to start, and the output end of the reducer 9 is equipped with a stirring rod 10. At this time, the stirring rod 10 will rotate on the inner wall of the bearing 7, and the outer surface of the stirring rod 10 is equipped with a turning plate 11. The turning plate 11 is spiral, so when the stirring rod 10 drives the turning plate 11 to rotate, the rotating turning plate 11 will drive the PE sheath material stored in the storage tank 1 from the bottom to the top through rotation, thereby turning the PE sheath material. When the PE sheath material is turned to the top of the material pile, due to the high temperature generated by the heating plate 5, the high temperature will dry the moisture in the PE sheath material, and the moisture in the PE sheath material will be evaporated by the high temperature, thereby achieving the function of dehumidification.

[0027] Embodiment 2

[0028] Based on the above Example 1, please refer to Figure 4-Figure 5 , including a control component including a shunt pipe 12, a feeding motor 13 is installed on one side surface of the shunt pipe 12, a screw rod 14 is installed on one side surface of the feeding motor 13, a humidity sensor 15 is installed on the inner wall of the storage tank 1, a controller 16 is installed on the outer surface of the storage tank 1, and the shunt pipe 12 is installed on one side surface of the outlet pipe 6.

[0029] There are two shunt pipes 12, which are respectively distributed on one side and the other side of the outlet pipe 6. A feeding motor 13 is installed on one side of each shunt pipe 12, and a screw rod 14 is correspondingly distributed on one side of each feeding motor 13. One end of the screw rod 14 is connected to the output end of the feeding motor 13, and one end of the screw rod 14 extends from one side of the shunt pipe 12 to its inner wall.

[0030] The humidity sensor 15 is electrically connected to the controller 16 , the controller 16 is electrically connected to the drive motor 8 , the controller 16 is electrically connected to the air pump, and the controller 16 is electrically connected to the heating plate 5 .

[0031] When the feeding motor 13 is started, it will drive the screw rod 14 connected to its output end to rotate. Because the outlet pipe 6 and the storage tank 1 are interconnected, and the outlet pipe 6 and the shunt pipe 12 are interconnected, when the screw rod 14 rotates, the PE sheath material in the storage tank 1 will flow into the outlet pipe 6, and then flow into the shunt pipe 12 from the outlet pipe. At this time, the rotating screw rod 14 will push the PE sheath material to move on the inner wall of the shunt pipe 12, and finally push the PE sheath material out from the other end of the shunt pipe 12 through rotation, thereby realizing the function of unloading.

[0032] The working principle and use process of the utility model are as follows: when it is necessary to use a PE sheath material dehumidification device, the top cover 2 installed on the top surface of the storage tank 1 is rotated, and the top cover 2 and the storage tank 1 are separated from each other by rotation. After the separation is completed, the PE sheath material to be stored is poured into the inner wall of the storage tank 1, and the PE sheath material is stored through the storage tank 1. After the pouring is completed, the top cover 2 is rotated again, so that the top cover 2 and the top surface of the storage tank 1 are in contact with each other, and the interior of the storage tank 1 is sealed by the mutual contact between the two. After the storage is completed, the vacuum pump 4 and the heating plate 5 are controlled by the controller 16 to start, because the interior of the storage tank 1 is connected to the outside through the shunt pipe 12, and the storage tank 1 is filled with PE sheath material. At this time, the vacuum pump 4 will discharge the moisture and air inside the storage tank 1, and make the interior of the storage tank 1 have a certain vacuum effect, and the material can be kept in this environment for a period of time, allowing moisture and other gas molecules to be released from the material. When added When the hot plate 5 is started, high temperature will be generated. At this time, the high temperature will radiate on the surface of the PE sheath material stored in the storage tank 1. Through long-term radiation, the temperature inside the storage tank 1 gradually increases. At this time, the controller 16 will control the drive motor 8 electrically connected to it to start. When the drive motor 8 is started, it will drive the reducer 9 connected to its output end to start, and the output end of the reducer 9 is equipped with a stirring rod 10. At this time, the stirring rod 10 will rotate on the inner wall of the bearing 7, and the outer surface of the stirring rod 10 is equipped with a turning plate 11. The turning plate 11 is spiral, so when the stirring rod 10 drives the turning plate 11 to rotate, the rotating turning plate 11 will drive the PE sheath material stored in the storage tank 1 from the bottom to the top through rotation, thereby turning the PE sheath material. When the PE sheath material is turned to the top of the material pile, because of the high temperature generated by the heating plate 5, the high temperature will dry the moisture in the PE sheath material, and the moisture in the PE sheath material will be evaporated by the high temperature, thereby realizing the dehumidification function.

[0033] When the dehumidified PE sheath material needs to be input into the injection molding machine, the feeding motor 13 is started. When the feeding motor 13 is started, the screw rod 14 connected to its output end is driven to rotate. Because the outlet pipe 6 and the storage tank 1 are interconnected, and the outlet pipe 6 and the shunt pipe 12 are interconnected, when the screw rod 14 rotates, the PE sheath material in the storage tank 1 will flow into the outlet pipe 6, and then flow into the shunt pipe 12 from the outlet pipe. At this time, the rotating screw rod 14 will push the PE sheath material to move on the inner wall of the shunt pipe 12, and finally push the PE sheath material out from the other end of the shunt pipe 12 through rotation, thereby realizing the function of material discharge.
