Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 The utility model provides a technical solution: a rapid drying device for plastic production, comprising a base 1, a heat preservation cylinder 2 is arranged above the base 1, support frames 21 are arranged on the front and rear sides of one side of the upper end of the base 1, and the support frames 21 are rotatably connected to the heat preservation cylinder 2, a drying chamber 9 is opened inside the heat preservation cylinder 2, a rotating door 3 is threadedly connected to one side of the heat preservation cylinder 2, and one end of the rotating door 3 extends into the interior of the drying chamber 9, and four equidistantly distributed annular heating blocks 11 are arranged on both sides of the outer wall of the drying chamber 9;

[0028] The transmission chamber 4 is provided on one side of the drying chamber 9. A stirring shaft 7 is rotatably provided on the upper and lower sides of the transmission chamber 4. One end of the stirring shaft 7 passes through and extends into the drying chamber 9. The outer wall of the stirring shaft 7 at one end inside the drying chamber 9 is welded with three groups of equally spaced stirring blades 8. Each group of stirring blades 8 is welded with four stirring blades 8 distributed in an annular shape and at equal distances.

[0029] The drying chamber 9 further comprises a purification box 16, which is arranged at the lower end of the heat-insulating cylinder 2, and one end of the purification box 16 extends into the interior of the drying chamber 9. The interior of the purification box 16 is provided with three equally spaced air activated carbon adsorption plates 17, and the lower end of the purification box 16 is provided with a plurality of through holes 19 distributed in a rectangular array.

[0030] It also includes a blowing chamber 12, which is opened on both sides of the upper end of the insulation cylinder 2. The blowing chamber 12 is connected to the drying chamber 9 through an air outlet 15. A fan 13 is installed at the upper end of the blowing chamber 12, and two heating wires 14 are provided below the fan 13.

[0031] During use, after adding the plastic pellet raw materials into the drying chamber 9, the servo motor 5 is started. The servo motor 5 will drive one of the stirring shafts 7 to rotate, and the other stirring shaft 7 will rotate synchronously under the meshing connection of the transmission gear 6, so that the stirring blades 8 are driven by the stirring shaft 7 to stir and turn the plastic pellet raw materials, so that the plastic pellet raw materials are evenly heated, thereby improving the drying effect of the plastic pellet raw materials. Then, by starting the fan 13 and the heating wire 14 to further dry the plastic pellet raw materials, the drying speed can be further increased and the drying efficiency can be improved.

[0032] See also Figure 1 A servo motor 5 is provided at the upper end of one side of the transmission chamber 4, and the output end of the servo motor 5 is connected to one of the stirring shafts 7 through a coupling, and the servo motor 5 provides power for the rotation of the stirring shaft 7;

[0033] See also Figure 1 and Figure 3 , the outer wall of the stirring shaft 7 at one end of the transmission chamber 4 is fixed with a transmission gear 6, and the transmission gears 6 are meshed and connected with each other. The meshing connection between the transmission gears 6 realizes the synchronous rotation of the stirring shaft 7;

[0034] See also Figure 1 and Figure 2 An electric telescopic rod 22 is installed on one side of the interior of the base 1. The output end of the electric telescopic rod 22 is rotatably connected to a connecting block 23, and one end of the connecting block 23 is connected to the heat preservation cylinder 2. When the electric telescopic rod 22 is started, the heat preservation cylinder 2 can be lifted, so that the dried plastic pellet raw materials can be discharged quickly.

[0035] See also Figure 5 , a filter screen 20 is provided at the upper end of the purification box 16, and the setting of the filter screen 20 can prevent the plastic pellet raw materials from entering the purification box 16;

[0036] See also Figure 5 Solid fragrances 18 are provided on both sides of the lower end of the purification box 16. The solid fragrances 18 produce a refreshing fragrance that neutralizes the purified air flow to avoid harming the health of the staff.

[0037] See also Figure 1 A feed port 10 is provided at the upper end of the heat preservation cylinder 2, and the feed port 10 is communicated with the drying chamber 9. The setting of the feed port 10 is convenient for the entry of the plastic pellet raw materials. After the plastic pellet raw materials are added, the feed port 10 can be closed by threading the cover with the feed port 10.

[0038] Working principle: When in use, the plastic pellet raw material is added from the feed port 10, and then the feed port 10 is closed through the cover, and the multiple annular heating blocks 11 are started to heat the drying chamber 9 to dry the plastic pellet raw material. At this time, the servo motor 5 is started, and one of the stirring shafts 7 can be rotated under the transmission of the coupling. The stirring shaft 7 will drive one of the transmission gears 6 to rotate. Since the two transmission gears 6 are meshed and connected, the other transmission gear 6 will be driven to rotate the other stirring shaft 7, so as to realize the synchronous rotation of the two stirring shafts 7. The rotation of the stirring shaft 7 will drive the stirring blades 8 to stir and turn the plastic pellet raw material, so that the heating of the plastic pellet raw material can be more evenly distributed. At the same time, the fan 13 and the electric heating wire 14 can be started. After the fan 13 is started, the air flow can be blown to the drying chamber 9 to air-dry the plastic pellet raw material, and the start of the electric heating wire 14 can heat the air flow, so that the temperature of the air flow blown to the plastic pellet raw material can be increased, thereby achieving the drying effect of the plastic pellet raw material, thereby further improving the drying effect and accelerating the drying effect. When the plastic pellets are stirred and turned, the air flow will pass through the gaps in the plastic pellets and enter the interior of the purification box 16, thereby improving the gas flow effect. The setting of the filter 20 can prevent the plastic pellets from entering the purification box 16. After the air flow with odor enters the purification box 16, it will be purified and filtered by the three air activated carbon adsorption plates 17, thereby avoiding pollution to the working environment. At the same time, the solid fragrance 18 will produce a refreshing fragrance that neutralizes the purified air flow, thereby avoiding harm to the health of the workers. When the drying of the plastic pellets is completed, the rotating door 3 can be moved out of the insulation cylinder 2 by rotating the rotating door 3. At this time, the electric telescopic rod 22 is started, and the output end of the electric telescopic rod 22 will drive the connecting block 23 to move upward synchronously. Since the output end of the electric telescopic rod 22 is rotatably connected to the connecting block 23, one end of the insulation cylinder 2 will be lifted, and then the support frame 21 is rotatably connected to the insulation cylinder 2, so that the insulation cylinder 2 can be rotated so that the internal plastic pellets can be poured out, making the discharge of the plastic pellets fast and convenient, thereby improving the overall drying efficiency.
