Abstract
Description
Technical Field
[0001] This utility model relates to the field of material drying technology, and specifically to a material drying device. Background Technology
[0002] Fertilizers are chemical fertilizers made by chemical or mixed methods that contain any two or three of the crop nutrients nitrogen, phosphorus, and potassium. Their function is to meet the comprehensive and balanced needs of agriculture for various nutrients under different production conditions. They are widely used in modern agriculture. During the production process, compound fertilizers need to be dried to avoid clumping caused by high humidity during storage.
[0003] In existing technology, after fertilizer granules are produced, they need to be transported by belt conveyor equipment. At the same time, multiple hot air blowers are set at intervals along the conveying path of the belt conveyor equipment to dry the fertilizer by blowing hot air. When the fertilizer is transported on the belt conveyor equipment, only the surface fertilizer granules can come into contact with the hot air flow, while the inner fertilizer granules cannot come into contact with the hot air flow. This can easily lead to poor drying effect of the fertilizer granules, which is not conducive to the filling and storage of fertilizer. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Improve the drying effect of materials.
[0028] This utility model is only used as an example of drying fertilizer with a drying device. Of course, the drying device can also be used to dry other granular materials, which will not be elaborated here.
[0029] Please see Figures 1-5 , Figures 1-5According to one embodiment of the present invention, a material drying device includes a conveying mechanism 1, a hot air mechanism 2, and a hydrothermal mechanism 3. The conveying mechanism 1 includes a conveying cylinder 11, a shaft 12, a spiral blade 13, and a driving component 14. The conveying cylinder 11 has a feeding section 1a and a discharging section 1b at opposite ends. The shaft 12 has a channel along its axial direction and multiple through holes 12a communicating with the channel. The shaft 12 is rotatably mounted inside the conveying cylinder 11. The spiral blade 13 is mounted on the shaft 12. The driving component 14 is fixed to one end of the conveying cylinder 11 and connected to one end of the shaft 12. The hot air mechanism 2 is connected to the channel and can convey hot air into the channel. The hydrothermal mechanism 3 is mounted on the conveying cylinder 11 and located between the feeding section 1a and the discharging section 1b, and is used to perform water bath heating on the conveying cylinder 11.
[0030] In actual use, fertilizer granules are conveyed into the conveying cylinder 11 via the feeding section 1a. At the same time, the driving component 14 drives the shaft 12 to rotate, thereby driving the spiral blades 13 to rotate, which in turn drives the fertilizer granules to move within the conveying cylinder 11. The hot air mechanism 2 delivers hot airflow into the channel. The hot airflow can enter the conveying cylinder 11 through multiple through holes 12a, making the hot airflow evenly distributed within the conveying cylinder 11. Meanwhile, the hydrothermal mechanism 3 heats the conveying cylinder 11 in a water bath, which can shorten the drying time of the fertilizer granules within the conveying cylinder 11 and improve the drying effect of the fertilizer.
[0031] It should be noted that the hydrothermal mechanism 3 is not limited to a specific structure, as long as it can heat the conveying cylinder 11 in a water bath, and no further details will be provided here.
[0032] In one embodiment, the hydrothermal mechanism 3 includes a sleeve 31 and a heating element 32. The sleeve 31 is mounted on the conveying cylinder 11 and forms an annular cavity for holding liquid between the sleeve 31 and the conveying cylinder 11. The heating element 32 is mounted on the sleeve 31 and is used to heat the liquid.
[0033] It is understandable that the annular cavity contains a heat-conducting liquid, which is heated by the heating element 32. The heat-conducting liquid can transfer heat to the conveying cylinder 11, and the heat can dry the fertilizer particles in the conveying cylinder 11.
[0034] It should be noted that the heating element 32 includes a plurality of heating cells fixed on the sleeve 31. When the heating cells are energized, they can heat the heat-conducting liquid.
[0035] Based on the above scheme, in order to increase the contact area between the conveying cylinder 11 and the heat-conducting liquid, specifically, a plurality of fins 11c are spaced apart on the conveying cylinder 11, and the plurality of fins 11c are all located in the annular cavity.
[0036] It should be noted that the hot air mechanism 2 includes a cover 21 and a blower 22. The cover 21 is fixed to the other end of the conveying cylinder 11, the blower 22 is connected to the cover 21, and the other end of the shaft 12 extends to the outside of the conveying cylinder 11 and is inserted into the cover 21.
[0037] Understandably, by blowing hot air into the cover 21 through the hair dryer 22, the hot air inside the cover 21 can enter the channel.
[0038] Based on the above scheme, in order to facilitate the filling of fertilizer granules output from the discharge section 1b, a bag-supporting mechanism 4 is specifically included. The bag-supporting mechanism 4 includes a hopper 41 and at least three opening support members 42. The hopper 41 is connected to the discharge section 1b. The at least three opening support members 42 are installed at intervals on the hopper 41. The at least three opening support members 42 can open the opening of the packaging bag so that the material discharged from the hopper 41 can fall into the packaging bag.
[0039] It should be noted that the opening support 42 is not limited to a particular structure; it is sufficient as long as it can open the packaging bag. No further details will be provided here.
[0040] In one embodiment, the support member 42 includes a base plate 421, an L-shaped plate 422, and a telescopic part 423. The base plate 421 is fixedly connected to the hopper 41, the L-shaped plate 422 is slidably connected to the base plate 421, the telescopic part 423 is mounted on the base plate 421 and its output end is connected to the L-shaped plate 422, and the telescopic part 423 can drive the L-shaped plate 422 to slide relative to the base plate 421.
[0041] Understandably, by simultaneously driving the three L-shaped plates 422 relative to the base plate 421 through the three telescopic parts 423, the three L-shaped plates 422 can open the opening of the packaging bag.
[0042] Furthermore, based on the above solution, in order to prevent the packaging bag from detaching from the three L-shaped plates 422 when the opening of the packaging bag is opened, specifically, the L-shaped plate 422 is provided with at least one pointed head that can pierce the packaging bag. It can be understood that when the L-shaped plate 422 opens the opening of the packaging bag, the pointed head can pierce the packaging bag.
[0043] In one embodiment, the telescopic part 423 is an electric cylinder. Of course, in other embodiments, the telescopic part 423 may also be a pneumatic cylinder or a hydraulic cylinder.
[0044] Based on the above scheme, in order to facilitate the conveying of fertilizer granules into the feed section 1a, specifically,
[0045] It also includes a feeding mechanism 5, which is connected to the feeding part 1a and can transport materials into the conveying cylinder 11.
[0046] In one embodiment, the feeding mechanism 5 includes a guide cylinder 51, a reduction motor 52, a rotating shaft 53, and stirring rods 54. The lower end of the guide cylinder 51 is connected to the feeding section 1a, and the upper end of the guide cylinder 51 is open. The reduction motor 52 is fixed to the top of the guide cylinder 51. The rotating shaft 53 is located inside the guide cylinder 51 and connected to the output end of the reduction motor 52. Multiple stirring rods 54 are installed on the rotating shaft 53. The rotation shaft 53 is driven to rotate by the reduction motor 52, thereby driving the stirring rods 54 to rotate and stir the fertilizer particles in the guide cylinder 51. This can prevent the fertilizer particles from arching inside the guide cylinder 51, which would cause feeding difficulties.
[0047] In addition, the lower end of the rotating shaft 53 extends into the feed section 1a, and the lower end of the rotating shaft 53 is also fixed with an auger blade 55.
[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
