Description

Technical Field

[0001] The present application relates to the technical field of medicinal fertilizer granules, and in particular to a drying device for medicinal fertilizer granules that can prevent pesticide degradation at low temperature. Background Art

[0002] Medicinal fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a certain proportion and stabilizing fertilizers and pesticides in a specific composite system through certain process technologies. Fertilizer is generally used as a carrier of pesticides. In the production process of medicinal fertilizer granules, the medicinal fertilizer granules need to be dried by a drying device.

[0003] In the related art, the fertilizer to be dried enters the storage bin through the feed port. At this time, the storage bin door is closed, and the feed port and the discharge port are blocked with baffles, so that the wind bin forms a relatively closed space. At this time, the negative pressure fan 1 and the negative pressure fan 2 are started at the same time to form an air flow in the wind bin. The rapid flow of air will quickly take away the moisture in the fertilizer, and the dirty gas with the smell of fertilizer will pass through the air filter device to reduce the turbidity and then be discharged out of the dryer. After the drying process is completed, open the storage bin door and the baffle at the discharge port to discharge the fertilizer out of the dryer.

[0004] However, during the drying process of the fertilizer granules, the fertilizer granules accumulate together, which results in the fertilizer granules accumulated inside being unable to be dried quickly, thereby requiring an increase in drying time. This, during prolonged drying, can easily lead to the fertilizer granules being exposed to high temperatures for a long time and degrading, making it difficult to dry the fertilizer granules and reducing the drying effect of the fertilizer granules. Therefore, those skilled in the art have provided a drying device for fertilizer granules at low temperatures to prevent pesticide degradation, in order to solve the problems raised in the above-mentioned background art.

[0029] In this embodiment, when the medicinal fertilizer granules are dried, the medicinal fertilizer granules are transported to the pad net 7 in the return frame 5 through the feed port 2, and then the interior of the drying box 1 is ventilated and heated by the fan provided on the drying box 1 to dry the medicinal fertilizer granules. Then, under the movement of the swing component 4, the rotating plate 3 is driven to swing continuously, and the rotating plate 3 drives the return frame 5 to swing continuously, thereby driving the medicinal fertilizer granules on the pad net 7 to swing continuously. When the medicinal fertilizer granules slide from the high place to the low place of the pad net 7, the medicinal fertilizer granules first pass through the thinning rod 9, and the medicinal fertilizer granules can be combed by the thinning rod 9 to avoid the medicinal fertilizer granules from piling up, thereby facilitating the rapid drying of the medicinal fertilizer granules, reducing the drying time of the medicinal fertilizer granules, avoiding the degradation of the medicinal fertilizer granules, and improving the drying effect of the medicinal fertilizer granules.

[0030] In a further embodiment, Figure 1-2 As shown, the swing assembly 4 includes a drive motor 41 fixedly arranged on one side of the drying box 1, the output shaft of the drive motor 41 is fixed with a first connecting rod 42, one end of the first connecting rod 42 is hinged with a second connecting rod 43, one end of the second connecting rod 43 is hinged with a third connecting rod 44 fixed to the rotating plate 3, and the limiting assembly 6 includes a limiting block 61 fixedly arranged on the inner wall of the drying box 1, and the top of the limiting block 61 is fixed with a rubber pad 62 that contacts the circular frame 5.

[0031] When the medicinal fertilizer granules are dried on the mat net 7, the movement of the driving motor 41 drives the first connecting rod 42 to rotate, and the first connecting rod 42 pulls the second connecting rod 43 to move, and the second connecting rod 43 drives the third connecting rod 44 to swing continuously, and the third connecting rod 44 drives the rotating plate 3 to swing continuously, and the rotating plate 3 drives the return frame 5 to swing continuously, thereby driving the medicinal fertilizer granules to slide back and forth, facilitating the rapid drying of the medicinal fertilizer granules, and during the swinging process of the return frame 5, the cooperation of the limit block 61 and the rubber pad 62 is convenient to limit the swing amplitude of the return frame 5 to avoid excessive swing amplitude of the return frame 5.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a material discharge chute 10 is provided on one side of the circular frame 5, and a first baffle 11 is slidably connected to the material discharge chute 10. A material discharge port 12 is provided on one side of the drying box 1, and a material guide plate 13 located below the circular frame 5 is fixed obliquely in the material discharge port 12.

A lifting component 15 is provided on one side of the drying box 1 to drive the second baffle 14 to move, and the second baffle 14 is connected to the first baffle 11 through a linkage component 16.

[0033] When the drying of the fertilizer granules is completed, the return frame 5 is rotated downward in the direction of the discharge port 12 to an angle, and then the second baffle 14 is driven to move upward under the movement of the lifting component 15 to open the discharge port 12. At the same time, the second baffle 14 drives the first baffle 11 to move upward through the linkage component 16 during the movement, and the discharge chute 10 can be opened. In this way, the fertilizer granules on the pad net 7 can fall onto the guide plate 13 through the discharge chute 10 and then be discharged outward through the guide plate 13, thereby facilitating the rapid discharge of the fertilizer granules and improving the discharge efficiency of the fertilizer granules.

[0034] Furthermore, guide blocks are fixed on both sides of the first baffle 11, and guide grooves that cooperate with the guide blocks are opened on both sides of the discharge chute 10. The guide blocks can slide in the guide grooves to maintain the stability of the movement of the first baffle 11, and the guide blocks and the guide grooves are connected by springs. The setting of the springs facilitates the automatic resetting of the first baffle 11 and facilitates the shielding of the discharge chute 10.

[0035] In a further embodiment, Figure 3-4 As shown, the lifting assembly 15 includes a slider 151 fixedly arranged on one side of the second baffle 14, and a slide groove 152 for the slider 151 to slide is opened on one side of the drying box 1.

When the granular fertilizers slide from the high place to the low place of the pad net 7, the granular fertilizers first pass through the thinning rod 9, and the granular fertilizers can be sorted by the thinning rod 9 to avoid the granular fertilizers from piling up, thereby facilitating the rapid drying of the granular fertilizers, reducing the drying time of the granular fertilizers, and avoiding The fertilizer granules are degraded, which improves the drying effect of the fertilizer granules. When the fertilizer granules are dried, the return frame 5 is rotated downward in the direction of the discharge port 12 to an angle, and then the slider 151 is driven to move upward under the movement of the electric telescopic rod 153. The slider 151 drives the second baffle 14 to move upward, and the discharge port 12 can be opened. At the same time, when the second baffle 14 moves upward, it drives the first striker 161 to move. When the first striker 161 moves to the bottom of the second striker 162, it can drive the second striker 162 to move upward synchronously. The second striker 162 drives the first baffle 11 to move upward, and the feed chute 10 can be opened. The fertilizer granules can fall onto the guide plate 13 through the feed chute 10 and then be discharged outward through the guide plate 13, thereby facilitating the rapid discharge of the fertilizer granules and improving the discharge efficiency of the fertilizer granules.
