[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the flow direction of the material is disrupted by the turbulence tube, resulting in chaotic flow of hot air and material, which increases the mixing effect of material and hot air.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, a material drying device includes a drying cylinder 4, which is provided with an air inlet, an air outlet and a discharge port 43, and a turbulence cylinder 5 for disrupting the airflow direction is provided inside the drying cylinder 4.

[0025] It also includes a hot air device for inputting hot air into the drying cylinder 4. Specifically, in this embodiment, the hot air device is a hot air furnace 1, and the hot air outlet of the hot air furnace 1 is connected to the air inlet of the drying cylinder 4 through an air inlet pipe 2.

[0026] It also includes a dust removal device that works in conjunction with the air outlet of the drying cylinder 4. Specifically, in this embodiment, the dust removal device is a cyclone dust collector 8, and the air outlet of the drying cylinder 4 is connected to the dust removal inlet of the cyclone dust collector 8 through an air outlet pipe 6.

[0027] It also includes a feeding device for adding the material to be dried into the drying cylinder 4. Specifically, in this embodiment, the feeding device is a feeding hopper 3, which is connected to the drying cylinder 4 or the air inlet pipe 2 via a pipe. The feeding hopper 3 is preferably connected to the air inlet pipe 2, so that the material to be dried first enters the air inlet pipe 2 from the feeding hopper 3, and then is dried by hot air for a certain period of time before entering the drying cylinder 4 for further drying, thus increasing the drying efficiency of the material.

[0028] In this embodiment, the air intake pipe 2 is configured as a coil-shaped structure extending vertically.

[0029] In this embodiment, an induced draft fan 7 is also included, which is preferably disposed between the drying cylinder 4 and the dust removal device.

[0030] Preferred, such as Figure 2 As shown, the drying cylinder 4 is configured as a cylindrical structure, specifically including a cylindrical wall 41, the two ends of which are sealed by side walls 42.

[0031] Preferred, such as Figure 2 As shown, the turbulence-dispersing cylinder 5 is configured as a cylindrical structure and is arranged coaxially with the drying cylinder 4. The two ends of the turbulence-dispersing cylinder 5 are respectively fixedly connected to the corresponding side plates 42.

[0032] In this embodiment, as Figure 1 As shown, the air inlet and discharge outlet 43 of the drying cylinder 4 are located on the cylinder wall 41; the air outlet of the drying cylinder 4 is located on the side wall 42 on the side away from the air inlet.

[0033] Working principle: When in use, the material to be dried is added from the feed hopper 3. The hot air discharged from the hot air furnace 1 enters the air inlet pipe 2 and carries the material into the drying cylinder 4 under the action of the wind.

[0034] The radial flow direction of the hot airflow and material within the drying cylinder 4: When the hot air carrying the material enters the drying cylinder 4, due to the obstruction of the baffle 5, the hot airflow and material entering the drying cylinder 4 from the air inlet pipe 2 will collide with the baffle 5. After colliding with the baffle 5, the hot airflow and material will be reflected (reflection direction as follows). Figure 2 As shown, Figure 2The indicated reflection direction is the ideal reflection direction after excluding the influence of subsequent hot airflow and materials, gravity, and other factors. The reflected hot airflow and materials will disperse to the surrounding area of ​​the turbulence cylinder 5. At the same time, the impact of subsequent hot airflow and materials will further disrupt the flow direction of the hot airflow and materials.

[0035] The axial flow direction of the hot air flow and materials in the drying cylinder 4 is: from the air inlet to the air outlet of the drying cylinder 4.

[0036] Because the flow direction of the material is disturbed by the turbulence cylinder 5, the flow direction of the hot air and the material becomes chaotic, which increases the mixing effect of the material and the hot air. At the same time, the disturbance reduces the flow rate of the hot air and the material, which indirectly increases the travel and residence time of the material in the drying cylinder 4, thereby increasing the drying effect of the material.

[0037] The material flows through the discharge port 43 and is discharged from the drying cylinder 4 by gravity. The hot air flows through the cyclone dust collector 8 and is discharged to the outside.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
