[0021] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0022] See Figs. 1-3A high-efficiency ventilated drying chamber for granular fertilizer includes a frame 1, a chamber body 2 mounted on the frame 1, a partition plate 3 mounted inside the chamber body 2, several air ducts 4 and 5 vertically staggered inside the chamber body 2, a damper assembly 6 alternately sealing both ends of the air ducts 4, and a damper assembly 7 alternately sealing both ends of the air ducts 5.

The partition plate 3 and the bottom of the chamber body 2 form a ventilation chamber 8. A ventilator 9 connected to the ventilation chamber 8 is arranged on the outside of the chamber body 2. Granular fertilizer is contained between the air ducts 4 and 5. A discharge valve 31 is arranged on the bottom side of the partition plate 3. A discharge port 21 is arranged at the bottom of the chamber body 2.
[0023] The damper assembly 6 includes an upper damper unit 61 that is separable and sealed at the top of several air ducts 4, a lower damper unit 62 that is separable and sealed at the bottom of several air ducts 4, a connecting rod 63 that connects the upper damper unit 61 and the lower damper unit 62, and several cylinders 64 for driving the upper damper unit 61 to rise and fall. The cylinders 64 are mounted on the frame 1.
[0024] The upper air damper unit 61 includes an upper support 611, a plurality of upper air dampers 612 disposed on the upper support 611, and a plurality of cylinders 64 respectively connected to the upper support 611. The upper air dampers 612 are detachably sealed at the top of the air duct 4.
[0025] The downwind door unit 62 includes a lower support 621 installed in the air chamber 8, a plurality of downwind doors 622 installed on the lower support 621, and a connecting rod 63 installed in the air duct 4. One end of the connecting rod 63 is connected to the upper air door 612, and the other end of the connecting rod 63 is connected to the downwind door 622.
[0026] The damper assembly 27 includes an upper damper unit 271 that is separable and sealed at the top of several air ducts 25, a lower damper unit 272 that is separable and sealed at the bottom of several air ducts 25, a connecting rod 273 that is connected between the upper damper unit 271 and the lower damper unit 272, and several cylinders 274 for driving the upper damper unit 271 to rise and fall.
[0027] The upper air damper unit 2 71 includes an upper support 2 711, a plurality of upper air dampers 2 712 disposed on the upper support 2 711, and a plurality of cylinders 2 74 respectively connected to the upper support 2 711. The upper air dampers 2 712 are detachably sealed at the top of the air duct 2 5.
[0028] Downwind door unit 2 72 includes a lower support 2 721 installed in the air chamber 8, a plurality of downwind doors 2 722 installed on the lower support 2 721, and a connecting rod 2 73 installed in the air duct 2 5. One end of the connecting rod 2 73 is connected to the upper air door 2 712, and the other end of the connecting rod 2 73 is connected to the downwind door 2 722.
[0029] The partition plate 3 is inverted conical, and the discharge valve 31 is located at the conical part of the partition plate 3. Furthermore, the valve stem of the discharge valve 31 passes through the bin body 2 and is equipped with a handwheel. The opening and closing of the discharge valve 31 is controlled by the handwheel. Alternatively, the discharge valve 31 is an electric valve, and the opening and closing of the discharge valve 31 is operated by remote control. The bottom of the bin body 2 is also inverted conical.
[0030] Specifically, if the chamber 2 is rectangular, four cylinders 64 and 74 are arranged on the frame 1 near the four corners of the chamber 2. If the drying chamber is cylindrical, four cylinders 64 and 74 are arranged in an array on the frame 1 near the outer edge of the drying chamber.
[0031] Furthermore, several air ducts 1 4 and several air ducts 2 5 are arranged in a rectangular array inside the chamber 2, or several air ducts 1 4 and several air ducts 2 5 are arranged in a ring array inside the chamber 2, and the air ducts 1 4 and air ducts 2 5 are arranged alternately to ensure that the airflow distributed into the air ducts 1 4 and air ducts 2 5 is more uniform.
[0032] The specific working process of this utility model:
[0033] First, several cylinders 64 are activated simultaneously. Cylinders 64 lower the upper support 611 of damper assembly 6 and the upper support 711 of damper assembly 7, thereby lowering the upper dampers 612 and 712 above the air ducts 4 and 5, sealing the air ducts 4 and 5 tightly. Then, the feed conveyor belt above the drying chamber is activated to transport the granular fertilizer into the silo 2, causing the granular fertilizer to fall onto the partition plate 3 in the gap between the air ducts 4 and 5. When the area above the partition plate 3 in the silo 2 is full... After the granular fertilizer does not exceed the upper end of the ventilation duct 1 4 and ventilation duct 2 5, start cylinder 1 64. Cylinder 1 64 drives the damper assembly 1 6, which causes the upper damper unit 1 61 on the damper assembly 1 6 to drive the lower damper unit 1 62 to rise through the connecting rod 1 63. The lower bracket 1 621 of the lower damper unit 1 62 drives the lower damper 1 622 to block the bottom end of the ventilation duct 1 4. At the same time, the upper damper 1 612 separates from the top end of the ventilation duct 1 4. At this time, the top end of the ventilation duct 2 5 is still blocked by the upper damper 2 712, and the bottom end of the ventilation duct 2 5 separates from the lower damper 2 722.
[0034] Start the ventilator 9, which delivers airflow to the air chamber 8. The airflow in the air chamber 8 enters the air duct 2 5 through the lower ends of several air ducts 2 5. Since the top of the air duct 2 5 is blocked by the upper air door, the airflow in the air duct 2 5 passes through the side ventilation holes, carries away the moisture from the granular fertilizer, and then flows out through the ventilation holes on the sides of the surrounding air ducts 2 5. Finally, it is discharged through the top of the ventilation hole 1, carrying away the moisture.
[0035] After the ventilator 9 runs continuously for a certain period of time to dry the granular fertilizer, the discharge valve 31 is opened. The granular fertilizer passes through the discharge valve 31, then through the air chamber 8, and is discharged onto the discharge belt through the discharge port 21.
[0036] By operating the ventilator 9, the granular fertilizer in the silo 2 is dried with a constant air volume. The air volume is more uniform and stable, and no heat source is required for drying, which reduces the energy consumption of drying granular fertilizer. After passing through the air chamber 8, the airflow is distributed to several air ducts 5. After drying the granular fertilizer, it is discharged through the adjacent air duct 4. The airflow distribution is more uniform and reasonable, which further improves the drying efficiency of granular fertilizer.
[0037] When there is no rush to dry the granular fertilizer, stop the ventilation fan 9. When the ventilation fan 9 is not running, the natural drying effect is also good through the setting of the air duct 1 4 and the air duct 2 5.
[0038] By using several cylinders 64 connected to the upper support 611 to drive several upper air doors 612 and lower air doors 622 to rise or fall together via connecting rod 63, and by using several cylinders 74 connected to the upper support 711 to drive several upper air doors 712 and lower air doors 722 to rise or fall together via connecting rod 73, the feeding and ventilation drying of granular fertilizer can be realized. The operation efficiency of the drying chamber is higher, and the applicability of the drying chamber is improved.
[0039] Both the bottom of the partition plate 3 and the bin body 2 are inverted cones. The side of the right bin body 2 of the ventilator 9 is connected to the air chamber 8, which makes the airflow in the air chamber 8 uniform and further improves the uniformity of the airflow distribution to the air duct 2 5, thus improving the efficiency of the drying bin.
[0040] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
