The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The granular fertilizer drying and curing equipment of the embodiment of the present application is described below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 8As shown, the granular fertilizer drying and curing equipment of the embodiment of the present application may include: a shell 1, a feeding mechanism 2, a hot pressing mechanism 3 and a discharge chute 4.

[0032] A heat supply device 11 is provided on the inner bottom wall of the shell 1 , and the heat supply device 11 is used to provide hot air to the interior of the shell 1 .

[0033] It should be noted that the heat supply device 11 described in this embodiment may be a hot air blower, and its specific structure has been disclosed in the prior art, so it will not be described in detail here.

[0036] Among them, the first fixed plate 321 and the second fixed plate 322 are respectively connected to the inner side wall of the shell 1, the two ends of the first rotating component 31 and the second rotating component 32 are respectively rotatably connected to the first fixed plate 321 and the second fixed plate 322, the first rotating component 31 and the second rotating component 32 are meshed and connected, the first rotating component 31 and the second rotating component 32 respectively include flexible pipe fittings 313, the flexible pipe fittings 313 are arranged between the first fixed plate 321 and the second fixed plate 322, and the flexible pipe fittings 313 are used to provide drying and curing space for granular fertilizer.

[0037] It should be noted that the first fixing plate 321 is fixedly connected to the inner side wall of the shell 1 , and the second fixing plate 322 is slidably connected to the inner side wall of the shell 1 .

[0038] It should be noted that the material of the flexible pipe 313 described in this embodiment may be cotton cloth, which has good air permeability and deformation ability and is relatively soft. The air permeability can enable the granular fertilizer to obtain a better drying effect, and the good deformation ability makes the flexible pipe 313 easier to tighten.

[0039] The driving device 33 is mounted on the outer wall of the housing 1 . The driving device 33 is connected to the second rotating assembly 32 . The driving device 33 is used to drive the second rotating assembly 32 to rotate.

[0040] It should be noted that the driving device 33 is meshedly connected with the second rotating component 32. The driving device 33 may include a driving motor, an outer cover and a driving gear. The outer cover passes through the outer wall of the shell 1. The output shaft of the driving motor is connected to the driving gear. The driving gear is located inside the outer cover, and the driving gear is meshedly connected with the second rotating component 32.

[0041] The first reset assembly 34 and the second reset assembly 340 are symmetrically arranged on the housing 1 . The first reset assembly 34 and the second reset assembly 340 are respectively connected to the second fixing plate 322 . The first reset assembly 34 and the second reset assembly 340 are respectively used to pull the second fixing plate 322 .

[0042] The stop component 35 is disposed on one side of the second rotating component 32 . The stop component 35 is connected to the second resetting component 340 . The stop component 35 is used to limit the second rotating component 32 .

[0043] The auxiliary component 37 is connected to the shell 1 . The auxiliary component 37 is located below the second fixing plate 322 . The auxiliary component 37 is connected to the feeding mechanism 2 . The auxiliary component 37 is used to receive the scattered granular fertilizer and deliver it into the interior of the feeding mechanism 2 .

[0044] The discharge chute 4 is connected to the shell 1 . The discharge chute 4 is located below the first fixing plate 321 . One end of the discharge chute 4 passes through the inner wall of the shell 1 , and one end of the discharge chute 4 extends to the outside of the shell 1 .

[0045] In the embodiment of the present application, a controller (not shown in the figure) is provided on the outer wall of the shell 1, and the heat supply device 11, the feeding mechanism 2 and the hot pressing mechanism 3 are respectively connected to the controller. Relevant technicians (for example, workers) can input operating data (for example, unloading speed, operating frequency of the stop component 35, rotation speed of the driving device 33, etc.) into the controller to ensure the normal operation of the device.

[0046] Specifically, relevant technicians use this equipment to dry and solidify a batch of granular fertilizers. First, the equipment is operated, the heat supply device 11 and the hot pressing mechanism 3 start to operate, and the granular fertilizer to be processed is placed inside the feeding mechanism 2 using an external feeding device. Under the action of gravity, the granular fertilizer enters the interior of the flexible pipe 313.

[0047] The driving device 33 drives the second rotating component 32 to rotate. At the same time, a plurality of spiral folds appear on the surface of the flexible tube 313. The flexible tube 313 rotates along with the first rotating component 31 and the second rotating component 32. The granular fertilizer rolls in the flexible tube 313 and moves along the folds toward the first fixed plate 321. Under the action of the heat supply device 11, the granular fertilizer inside the flexible tube 313 is dried.

[0048] After a certain period of time (which can be determined according to actual conditions), the controller sends an operation signal to the stop component 35, and the stop component 35 can be clamped at the second rotating component 32, and the other end of the first rotating component 31 and the second rotating component 32 stops rotating. Under the action of the driving device 33, one end of the first rotating component 31 and the second rotating component 32 continues to rotate.

[0049] At this time, the feeding mechanism 2 stops feeding, and the flexible pipe 313 is tightened. The flexible pipe 313 can apply a certain force to the granular fertilizer inside it, thereby achieving a compaction and solidification effect, and improving the crush resistance of the granular fertilizer.

[0050] When the flexible pipe 313 is tightened, the distance between the first rotating component 31 and the second rotating component 32 is reduced, the first reset component 34 and the second reset component 340 are extended, and after the compaction and solidification of the granular fertilizer is completed, the stop component 35 is reset, the other end of the first rotating component 31 and the second rotating component 32 continues to rotate, the first reset component 34 and the second reset component 340 retract, the flexible pipe 313 returns to its original state, and the granular fertilizer moves toward the first fixed plate 321 until it falls into the inside of the discharge trough 4, and is finally temporarily stored by an external collection device. In the above process, the drying process and the curing process can be completed in the same equipment.

[0051] As a possible situation, in order to improve the drying and curing efficiency of granular fertilizer, the number of the first rotating components 31 and the second rotating components 32 in the hot pressing mechanism 3 can also be set to multiple, for example: 4, 6, 8, etc., and its specific connection structure and working method have been disclosed in the above technical solution, so they will not be repeated here.

[0052] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the first rotating assembly 31 and the second rotating assembly 32 further include a first ring body 311 , a first gear ring 312 , a second ring body 314 and a second gear ring 315 , respectively.

[0053] Among them, the first ring body 311 is rotatably connected to the first fixed plate 321, the second ring body 314 is rotatably connected to the second fixed plate 322, the first ring gear 312 is sleeved on the outside of the first ring body 311, the second ring gear 315 is sleeved on the outside of the second ring body 314, the first ring gear 312 in the first rotating component 31 is meshed and connected with the first ring gear 312 in the second rotating component 32, the second ring gear 315 in the first rotating component 31 is meshed and connected with the second ring gear 315 in the second rotating component 32, the two ends of the flexible tube 313 are respectively connected to the first ring body 311 and the second ring body 314, and the driving device 33 is meshed and connected with the first ring gear 312 in the second rotating component 32.

[0054] It should be noted that the first ring body 311 and the first fixing plate 321 described in this embodiment are rotatably connected via a bearing (not shown in the figure).

[0055] In one embodiment of the present application, Figure 5 and Figure 6As shown, the first reset assembly 34 and the second reset assembly 340 respectively include a first cover body 341, a limiting plate 342 and a tension spring 343.

[0056] Among them, the first cover body 341 passes through the outer wall of the shell 1, the limiting plate 342 is slidably connected to the first cover body 341, the limiting plate 342 is connected to the second fixing plate 322, one end of the tension spring 343 is connected to the limiting plate 342, and the other end of the tension spring 343 is connected to the inner wall of the first cover body 341.

[0057] In one embodiment of the present application, Figure 5 , Figure 6 and Figure 7 As shown, the stopping assembly 35 includes a clamping plate 352 , a supporting plate 353 and a cylinder 354 .

[0058] Among them, a notch 351 is provided on the second gear ring 315 in the second rotating component 32, the clamping plate 352 is slidably connected to the inner wall of the first cover body 341 in the second reset component 340, one end of the support plate 353 is connected to the limit plate 342 in the second reset component 340, the support plate 353 passes through the inner wall of the clamping plate 352 and the first cover body 341 in the second reset component 340, and the support plate 353 is slidably connected to the clamping plate 352 and the first cover body 341 in the second reset component 340.

[0059] The cylinder 354 is installed on the support plate 353 , and the telescopic rod of the cylinder 354 passes through the outer wall of the first cover body 341 in the second reset assembly 340 , and the telescopic rod of the cylinder 354 is slidably connected to the first cover body 341 in the second reset assembly 340 , and the telescopic rod of the cylinder 354 is connected to the clamping plate 352 .

[0060] Specifically, during the operation of the hot pressing mechanism 3, first, the driving device 33 is meshed and connected with the first ring gear 312 in the second rotating component 32, and the first ring gear 312 in the second rotating component 32 is meshed and connected with the first ring gear 312 in the first rotating component 31, and the first ring gear 312 drives the first ring body 311 to rotate, and the first ring body 311 drives the flexible tube 313 to rotate, and the granular fertilizer rolls and moves in the flexible tube 313, thereby drying the granular fertilizer.

[0061] After a certain period of time, the stop component 35 operates, and when the second ring gear 315 in the second rotating component 32 rotates to a preset position (this working condition can be obtained through a position sensor), the cylinder 354 pushes the clamping plate 352 to be clamped in the notch 351, and the second ring gear 315 in the first rotating component 31 and the second rotating component 32 stops rotating, the flexible pipe 313 is tightened, and a force is applied to the granular fertilizer inside the flexible pipe 313 to mechanically compact the granular fertilizer, thereby achieving solidification of the granular fertilizer.

[0062] When the flexible tube 313 is tightened, the axial distance of the flexible tube 313 is reduced, and one end of the first rotating assembly 31 and the second rotating assembly 32 moves, thereby driving the limit plate 342 to move inside the first cover body 341. When the curing process is completed, under the action of the tension spring 343, the limit plate 342 and the second fixed plate 322 are reset at the same time, and the above steps are repeated. The equipment can continuously dry and cure the granular fertilizer.

[0063] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the hot pressing mechanism 3 further includes a friction assembly 36 , and the friction assembly 36 includes a friction block 361 , two limiting columns 362 and two springs 363 .

[0064] Among them, the friction block 361 conflicts with the second ring body 314 in the first rotating component 31 and the second ring body 314 in the second rotating component 32; the two limiting columns 362 are respectively connected to the friction block 361, one end of the limiting column 362 passes through the second fixed plate 322, the limiting column 362 is slidably connected to the second fixed plate 322, and the two springs 363 are respectively mounted on the corresponding limiting columns 362.

[0065] It should be noted that, in order to further increase the effect of the spiral fold on the flexible pipe 313 , the friction block 361 abuts against the second ring body 314 to reduce the rotation speed of the two second ring bodies 314 , thereby ensuring that the granular fertilizer rolls and moves in the flexible pipe 313 .

[0066] In one embodiment of the present application, Figure 3 and Figure 8 As shown, the auxiliary component 37 includes a collecting plate 371 and two screw conveyors 372 .

[0067] Among them, both ends of the collecting plate 371 are connected to the inner wall of the shell 1, the collecting plate 371 is located below the second fixed plate 322, the screw feeder 372 is connected to the shell 1, and the screw feeder 372 is connected to the collecting plate 371 and the feeding mechanism 2 respectively.

[0068] Specifically, during the tightening process of the flexible pipe 313, the granular fertilizer at the end of the flexible pipe 313 will be squeezed out, and this part of the granular fertilizer will fall on the collecting plate 371. Through the conveyance of the screw conveyor 372, this part of the granular fertilizer will be sent to the interior of the feeding mechanism 2, so that it will re-enter the interior of the flexible pipe 313.

[0069] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 8As shown, a liquid collecting assembly 12 is provided above the shell 1 , and the liquid collecting assembly 12 includes a cover 121 , two liquid collecting parts 122 , two drainage pipes 123 and a plurality of guide strips 124 .

[0070] The cover 121 is disposed on the shell 1 , two liquid collecting parts 122 are integrally formed on both sides of the cover 121 , two drain pipes 123 are respectively connected to the corresponding liquid collecting parts 122 , and a plurality of guide strips 124 are respectively disposed on the inner top wall of the cover 121 .

[0071] It should be noted that during the drying process of the granular fertilizer, the high-humidity gas moves upward and encounters the cover body 121. The water molecules in the high-humidity gas condense into water droplets on the cover body 121. The water droplets gather in the liquid collecting part 122 along the guide strip 124 and are discharged into the external environment through the drain pipe 123, which can ensure that the high-humidity gas is discharged in time, thereby ensuring the drying effect of the granular fertilizer.

[0072] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 8 As shown, the feeding mechanism 2 includes a collecting trough 21 , two first feeding pipes 22 , two electromagnetic flow valves 23 and two second feeding pipes 24 .

[0073] Among them, one end of the two first feed pipes 22 is connected to the collecting tank 21, two electromagnetic flow valves 23 are installed on the corresponding first feed pipes 22, two second feed pipes 24 are connected to the corresponding first feed pipes 22, and the two second feed pipes 24 extend to the inside of the corresponding flexible pipe 313.

[0074] It should be noted that the electromagnetic flow valve 23 described in this embodiment is connected to the controller, the electromagnetic flow valve 23 can control the feeding speed, the second feed pipe 24 is arranged at an angle, and one end of the second feed pipe 24 extends to the inside of the flexible pipe 313, which can prevent the granular fertilizer from spilling to the outside of the flexible pipe 313 during the feeding process. When the flexible pipe 313 is tightened, one end of the second feed pipe 24 can be detached from the flexible pipe 313.

[0075] In one embodiment of the present application, Figure 1 and Figure 8 As shown, it also includes a heat utilization component 5, which includes a pump body 51, an air outlet pipe 52 and an air inlet pipe 53.

[0076] Among them, the pump body 51 is arranged on the shell 1, one end of the air inlet pipe 53 is connected to the pump body 51, the other end of the air inlet pipe 53 is connected to the liquid collecting component 12, one end of the air outlet pipe 52 is connected to the pump body 51, and the other end of the air outlet pipe 52 is connected to the feeding mechanism 2.

[0077] It can be understood that, under the action of the pump body 51, the high-humidity and high-temperature gas can enter the interior of the feeding mechanism 2 through the air inlet pipe 53 and the air outlet pipe 52, thereby pre-drying the granular fertilizer, which can improve the thermal utilization rate of the equipment and prevent the high-temperature and high-humidity gas from overflowing through the discharge trough 4 and affecting the granular fertilizer that has been dried and solidified.

[0078] In summary, the granular fertilizer drying and curing equipment of the embodiment of the present application constructs a thermal environment in the shell with the help of a heat supply device. Under the action of the driving device, the flexible pipe can rotate at a uniform speed, and at the same time, a plurality of spiral folds are formed on its surface. The granular fertilizer inside the flexible pipe continuously rolls along the spiral folds, thereby achieving the drying of the granular fertilizer. Then, under the action of the stop component, one end of the flexible pipe stops rotating, and the flexible pipe begins to shrink, thereby applying force to the granular fertilizer, and compacting and curing the granular fertilizer with mechanical pressure, thereby improving the granular fertilizer's resistance to crushing. In the above process, the drying process and the curing process can be completed in the same equipment.
