DETAILED DESCRIPTION

[0019] The embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0020] The air drying device for engineering plastic granulation of the embodiments of the present application will be described below in conjunction with the drawings.

[0021] As Figures 1-4The utility model discloses a drying device for engineering plastics granulation, including support seat 1 and drying assembly 2, wherein, drying assembly 2 includes drive motor 21, interconnection board 22, first drying cylinder 23, second drying cylinder 24, hot air machine 25, blow pipe 26, control mechanism 27, two exhaust mechanisms 28, two air supply pipes 29, two drying pipes 210 and connecting plate 211, wherein, drive motor 21 is installed on support seat 1.

[0022] It should be explained that the first drying cylinder 23 or the second drying cylinder 24 is provided with an adding port of raw materials at one end, and a sealing plate is installed on the adding port, so that the plastic raw materials can be added into the first drying cylinder 23 or the second drying cylinder 24 by opening the sealing plate.

[0023] The interconnection board 22 is installed on the output end of the drive motor 21. The first drying cylinder 23 is installed on one end of the interconnection board 22. The second drying cylinder 24 is installed on the other end of the interconnection board 22, and the opposite end of the second drying cylinder 24 and the first drying cylinder 23 is a circular truncated cone.

[0024] It should be explained that the circular truncated cone-shaped first drying cylinder 23 and the second drying cylinder 24 can reduce the diameter of the flow of plastic raw materials, so that the plastic raw materials flow slowly, thereby increasing the drying effect of the plastic raw materials.

[0025] The two ends of the connecting plate 211 are connected with the first drying cylinder 23 and the second drying cylinder 24 respectively, the hot air machine 25 is installed on the connecting plate 211, and the blow pipe 26 is installed on the blowing end of the hot air machine 25.

[0026] It should be explained that the drying pipes 210 in the first drying cylinder 23 and the second drying cylinder 24 are respectively located at the adjacent end of the first drying cylinder 23 and the second drying cylinder 24, so that the drying pipe 210 in the lower drying cylinder is always above the drying cylinder, so that the air discharged by the drying pipe 210 in the drying cylinder can be blown downward, and the drying pipe 210 is spiral, and a plurality of drying holes are distributed on the drying pipe 210, thereby the air discharged by the plurality of drying holes can dry the falling granulation raw materials.

[0027] The control mechanism 27 is arranged on the connecting plate 211, and the control mechanism 27 is connected with the blow pipe 26.

[0028] It should be explained that the maximum temperature of the hot air blown by the hot air machine 25 cannot exceed the tolerance value of the plastic raw materials, so as to avoid melting the plastic raw materials when drying the plastic raw materials.

[0029] Two air exhaust mechanisms 28 are arranged on the first and second air drying cylinders 23 and 24 respectively, two air supply pipes 29 are arranged on the regulating mechanism 27, and two air drying pipes 210 are installed in the first and second air drying cylinders 23 and 24 respectively and connected with the corresponding air supply pipes 29.

[0030] Specifically, in actual operation, the related personnel need to dry the raw materials for plastic granulation to shorten the melting speed of the plastic granulation raw materials.

[0031] When the granulation raw materials need to be dried, first, the first air drying cylinder 23 is rotated to the upper side of the second air drying cylinder 24 by controlling the switch, and then the granulation raw materials to be dried are added into the first air drying cylinder 23. At the same time of adding the granulation raw materials, the hot air blower 25 is controlled to operate, the air blown by the hot air blower 25 enters the regulating mechanism 27 through the air blowing pipe 26, and then flows into the air supply pipe 29 and the air drying pipe 210 under the control of the regulating mechanism 27. The air discharged from the air drying pipe 210 on the second air drying cylinder 24 blows downward (the air drying pipe 210 in the first air drying cylinder 23 is in a closed state under the control of the regulating mechanism 27), thereby the granulation raw materials falling from the first air drying cylinder 23 can be blown, and the air entering the second air drying cylinder 24 can increase the air pressure in the second air drying cylinder 24. Under the action of the air pressure, the air flows upward into the first air drying cylinder 23, and at the same time, the granulation raw materials can be blown again. Finally, the air is discharged from the air exhaust mechanism 28 on the first air drying cylinder 23. After the granulation raw materials in the first air drying cylinder 23 enter the second air drying cylinder 24, the first air drying cylinder 23 and the second air drying cylinder 24 are driven to rotate by the driving motor 21, so that the positions of the first air drying cylinder 23 and the second air drying cylinder 24 can be exchanged. At this time, the air drying principle is the same as that above, and the granulation raw materials can be continuously dried.

[0032] By controlling the downward flow of the granulation raw materials from the small opening, the air blowing effect on the raw materials is better, thereby the drying speed is significantly improved. The air blows upward and is discharged, and in the process, the air contacts the downward flowing granulation raw materials again, thereby the drying effect is further enhanced.

[0033] In an embodiment of the present application, as shown in Figure 1 The second air drying cylinder 24 and the first air drying cylinder 23 are communicated with each other at opposite ends.

[0034] In an embodiment of the present application, as shown in Figure 3 The regulating mechanism 27 comprises an adjusting shell 271, a sealing block 272 and two communication openings 273. The adjusting shell 271 is installed on the connecting plate 211. The sealing block 272 is slidingly arranged in the adjusting shell 271. The two communication openings 273 are oppositely arranged on the adjusting shell 271.

[0035] Specifically, in the actual implementation process, in the initial state, the sealing block 272 is below the adjusting shell 271 under the action of gravity, when the driving motor 21 drives the first air drying cylinder 23 and the second air drying cylinder 24 to rotate, the adjusting shell 271 also rotates, and the sealing block 272 is above the adjusting shell 271 after the adjusting shell 271 rotates, at this time, under the action of gravity, the sealing block 272 will automatically move down, at this time, the sealing block 272 seals one of the communication ports 273, if after rotation, the first air drying cylinder 23 is above the second air drying cylinder 24, the sealing block 272 will seal one end of the air supply pipe 29 corresponding to the first air drying cylinder 23, and similarly, when the second air drying cylinder 24 is above the first air drying cylinder 23, the sealing block 272 will seal one end of the air supply pipe 29 corresponding to the second air drying cylinder 24.

[0036] In an embodiment of the present application, as shown in Figure 4 The air exhaust mechanism 28 includes an air exhaust cylinder 281, a plurality of air exhaust ports 282, a sliding rod 283, a limiting disc 284 and a sealing disc 285, wherein the air exhaust cylinder 281 is installed on the first air drying cylinder 23, and the air exhaust cylinder 281 communicates with the first air drying cylinder 23.

[0037] It should be noted that who is above in the first air drying cylinder 23 and the second air drying cylinder 24 performs air exhaust, thereby the wind direction can be controlled to flow upwards, and the wind direction can be contacted with the downward flowing granulation raw materials again when flowing upwards.

[0038] The plurality of air exhaust ports 282 are circularly arranged on one end of the air exhaust cylinder 281. The sliding rod 283 penetrates and slides on the air exhaust cylinder 281. The limiting disc 284 is installed on one end of the sliding rod 283.

[0039] It should be noted that a sealing gasket is installed on the sealing disc 285, which can improve the sealing effect of the sealing disc 285 on the air exhaust port 282.

[0040] The sealing disc 285 is installed on the end of the sliding rod 283 away from the limiting disc 284, and the sealing disc 285 is slidingly arranged in the air exhaust cylinder 281.

[0041] Specifically, in the actual implementation process, when the first air drying cylinder 23 is below the second air drying cylinder 24, the sealing disc 285 on the first air drying cylinder 23 moves down under the action of gravity, so that the sealing disc 285 contacts the bottom end of the air exhaust cylinder 281 and seals the air exhaust port 282 at the bottom end of the air exhaust cylinder 281, and the sealing disc 285 in the second air drying cylinder 24 moves down under the action of gravity, so that the sealing disc 285 no longer seals the air exhaust port 282, and the air in the second air drying cylinder 24 can be exhausted through the air exhaust port 282.

[0042] In conclusion, the air drying device for engineering plastic granulation, by controlling the downward flow of the granulation raw materials from the small opening, makes the wind blowing on the raw materials more effective, thereby significantly improving the drying speed, and the blown wind flows upward and is discharged, and in this process, the granulation raw materials flowing downward are contacted again, further enhancing the air drying effect.
