DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figures 1-5 In the embodiments of the utility model, the drying mechanism for thermoplastic elastomer production comprises an inner shell 1, the outer surface of the inner shell 1 is nested with a heat exchange coil 3, the outer surface of the inner shell 1 is nested with an outer shell 4, the upper end face of the outer shell 4 is detachably connected with a cover body 2.

[0025] The upper surface of the cover body 2 is fixedly connected with a stepping motor 201, the output end of the stepping motor 201 is fixedly connected with a rotating shaft 202, the outer surface of the rotating shaft 202 is nested with a stirring mechanism 5, the stirring mechanism 5 comprises a stirring frame 501, an air outlet pipe 506 and a scraping brush 507, the stirring frame 501 is nested and detachably connected to the outer surface of the rotating shaft 202, the air outlet pipe 506 is fixedly connected to the outer surface of the stirring frame 501, and the scraping brush 507 is fixedly connected to the lower surface of the stirring frame 501.

[0026] Specifically, the installation of the air pipe rotary joint 203 does not affect the rotation of the shaft 202, and the air pipe rotary joint 203 and the air outlet 204 are connected. Therefore, outside air can pass through the air pipe rotary joint 203, the air outlet 204, the air passage 502, and finally be discharged from the interior of the inner shell 1 through the air outlet pipe 506. Since the air is heated and the blowing position is changed in conjunction with the stirring frame 501, it is beneficial to the uniform heat distribution inside the inner shell 1. In addition, the hot air with a large moisture content enters the heat exchange coil 3 through the connecting pipe 206, and heats the outer wall of the inner shell 1 through the heat exchange coil 3, reducing the moisture content of the raw materials while heating the air with a large moisture content. The material is reused, allowing it to be heated on both sides, thus improving the drying efficiency of the device. Outside air can pass through the air pipe rotary joint 203, the air outlet 204, and the air passage 502, and finally be discharged into the interior of the inner shell 1 through the air outlet pipe 506. Since the air is heated and the blowing position is changed in conjunction with the stirring rack 501, it is beneficial to the uniform heat distribution inside the inner shell 1. The hot air with a large moisture content enters the heat exchange coil 3 through the connecting pipe 206, and heats the outer wall of the inner shell 1 through the heat exchange coil 3. This reduces the moisture content of the raw material and reuses the air with a large moisture content, allowing the material to be heated on both sides and improving the drying efficiency of the device.

[0027] Example 1

[0028] like Figures 1-4 As shown, a plug 101 is threadedly connected to the lower surface of the inner shell 1, a controller 6 is fixedly connected to the lower surface of the inner shell 1, an electric heater 103 is fixedly connected inside the inner shell 1, a feed pipe 102 is fixedly connected to the lower surface of the inner shell 1, a feed square pipe 205 is fixedly connected to the upper surface of the cover 2, a connecting pipe 206 is embedded and fixedly connected to the upper surface of the cover 2, the other end of the connecting pipe 206 is inserted into the heat exchange coil 3, and a support leg 401 is fixedly connected to the lower surface of the outer shell 4.

[0029] In this embodiment, the plug 101 is used to limit the end of the rotating shaft 202. The controller 6 works with the electric heater 103 to heat the inner shell 1 near the center and the rotating shaft 202. The feed square tube 205 is used for feeding, and a tube cover is hinged on the feed square tube 205. The connecting tube 206 is used to realize the gas conduction between the inside of the cover 2 and the heat exchange coil 3.

[0030] Example 2

[0031] Based on Example 1, in order to overcome the problem of not being able to utilize the heat in the humid air in Example 1.

The outer surface of the rotating shaft 202 is provided with an air outlet 204. The interior of the stirring rack 501 is provided with an air passage 502, and the air passage 502 and the air outlet 204 are matched.

[0033] In the embodiment, after the inner shell 1 is filled with materials, the rotating shaft 202 is connected with the air pump outside through the air pipe rotary joint 203, the air pipe rotary joint 203 does not affect the rotation of the rotating shaft 202, and the air pipe rotary joint 203 and the air outlet hole 204 are in communication, so that the air outside can pass through the air pipe rotary joint 203, the air outlet hole 204, the air duct 502 and finally the air outlet pipe 506 to be discharged to the inside of the inner shell 1. Since the air is heated and the blowing position is changed by the stirring frame 501, the heat distribution in the inner shell 1 is uniform, and the hot air with a large water content enters the heat exchange coil 3 through the connecting pipe 206, thereby heating the outer wall of the inner shell 1, reducing the water content of the materials and recycling the air with a large water content, so that the materials are heated on both sides, and the drying efficiency of the device is improved.

[0034] As shown in Figures 1-5 The stirring mechanism 5 further comprises a sliding block 503, a connecting block 504 and stirring blades 505.

The side surface of the connecting block 504 is threadedly connected with a bolt, and the number of the stirring blades 505 is multiple, and adjacent stirring blades 505 along the axial direction of the rotating shaft 202 are mirror images of each other.

[0035] In the embodiment, on the basis that the stirring frame 501 is rotatable, the stirring blades 505 can be installed on the outer surface of the stirring frame 501 by means of the sliding block 503, the connecting block 504 and the bolt, and the installation direction can be adjusted, so that the material is subjected to different stress directions when the stirring blades 505 stir, which is beneficial to the tumbling of the material and further improves the uniformity of heat distribution in the material.
