[0026] A vegetable drying device for waste heat recovery comprises a drying box 1, a mounting ring 2 is provided on the drying box 1, a box cover 3 is provided on the mounting ring 2, a dryer 4 is provided inside the drying box 1, a drying tube 41 is provided in a circumferential array on the output end of the dryer 4, a drying hole 42 is provided on the drying tube 41, a mounting hole is provided on the mounting ring 2, a drying ring 5 is rotatably provided inside the mounting hole, a drying net 51 is provided on the inner ring surface of the drying ring 5, a heat conducting sheet 52 is provided in a circumferential array on the outer ring surface of the drying ring 5, a drain pipe 11 is provided at the bottom of the drying box 1, an exhaust pipe 31 is provided at the top of the box cover 3, a recovery cover 6 is provided on the mounting ring 2, the heat conducting sheet 52 is located inside the recovery cover 6, an air inlet pipe 7 and an air outlet pipe 71 are provided on the recovery cover 6, and the air inlet pipe 7 and the exhaust pipe 31 are connected to each other. They are connected, so that through the cooperation of the mounting ring 2, the drying ring 5, the heat conducting sheet 52, the exhaust pipe 31 and the air inlet pipe 7, the hot air discharged from the drying box 1 is transported to the inside of the recovery cover 6, which can not only utilize the residual heat of the hot air discharged from the drying box 1 to assist in heating the drying ring 5, thereby improving the drying efficiency of the vegetables on the drying net 51, but also utilize the driving force of the hot air discharged from the drying box 1 to drive the drying net 51 to rotate, thereby evenly drying the vegetables on the drying net 51, and through the cooperation of the dryer 4 and the drying tube 41, the hot air discharged from the drying hole 42 blows up the vegetables on the drying net 51, and then turns the vegetables over during the rotation of the drying net 51, further ensuring the effect of evenly drying the vegetables on the drying net 51.

[0027] like Figure 3 and Figure 4 As shown, a waterproof box 43 is provided inside the drying box 1, and the top surface of the waterproof box 43 is an inclined structure. The dryer 4 is arranged inside the waterproof box 43, and the output end of the dryer 4 extends to the top of the waterproof box 43. The drying pipe 41 is arranged on the end body extending from the output end of the dryer 4 to the top of the waterproof box 43. The inclined structure of the top surface of the waterproof box 43 prevents water on the vegetables from accumulating on the waterproof box 43, so that the water on the vegetables can be discharged from the drying box 1 in time.

[0028] like Figures 2 to 5 As shown, the mounting ring 2 is divided into an upper ring block 21 and a lower ring block 22 by a mounting hole. The lower ring block 22 is connected to the drying box 1. The box cover 3 is arranged on the upper ring block 21. The lower ring block 22 and the upper ring block 21 are both connected to the recovery cover 6. Therefore, through the cooperation of the upper ring block 21 and the lower ring block 22, the drying ring 5 can rotate on the mounting ring 2.

[0029] like Figures 2 to 5 As shown, the recovery cover 6 includes an upper ring plate 61, a side ring plate 62 and a lower ring plate 63. The lower ring plate 63 is connected to the lower ring block 22, and the upper ring plate 61 is connected to the upper ring block 21. Therefore, through the cooperation of the upper ring plate 61, the side ring plate 62 and the lower ring plate 63, the drying ring 5 rotates on the mounting ring 2 while the upper ring block 21 and the lower ring block 22 remain stable.

[0030] like Figure 1 and Figure 2 As shown, the air inlet pipe 7 and the air outlet pipe 71 are symmetrically arranged on the side ring plate 62, and the air inlet pipe 7 and the air outlet pipe 71 are both tangent to the rotation trajectory of the heat conducting plate 52, so that the residual heat of the hot air discharged from the drying box 1 through the air inlet pipe 7 is used to auxiliary heat the drying ring 5. At the same time, the driving force of the hot air discharged from the drying box 1 through the air inlet pipe 7 drives the drying net 51 to rotate, and the gas that has utilized the residual heat inside the recovery cover 6 is discharged through the air outlet pipe 71.

[0031] like Figure 1 and Figure 2 As shown, a connecting hose 72 is provided on the air intake pipe 7 , and the connecting hose 72 is connected to the exhaust pipe 31 , so that the hot air discharged from the exhaust pipe 31 is transported to the inside of the air intake pipe 7 through the connecting hose 72 .

[0032] like Figures 1 to 3 As shown, the bottom surface of the drying box 1 is provided with supporting feet 12 in a circumferential array, and the top surface of the box cover 3 is symmetrically provided with handles 32, so that the drying box 1 is kept stable by the supporting feet 12, and the box cover 3 is opened or closed by the handles 32.

[0033] Working principle: The dryer 4 transports hot air to the drying net 51 through the drying holes 42 on the drying tube 41 to dry the vegetables. After drying the vegetables, the hot air transported to the drying net 51 will be transported to the inside of the recovery cover 6 through the exhaust pipe 31, the connecting hose 72 and the air inlet pipe 7. The hot air transported to the inside of the recovery cover 6 will drive the drying ring 5 connected to the heat conducting plate 52 to rotate on the mounting ring 2, so that the drying ring 5 drives the vegetables on the drying net 51 to rotate, and then the vegetables on the drying net 51 are evenly dried. At the same time, the hot air transported to the inside of the recovery cover 6 will also assist in heating the drying ring 5, so as to improve the drying efficiency of the vegetables on the drying net 51. During the rotation of the drying net 51, the hot air discharged from the drying holes 42 can also blow up the vegetables on the drying net 51, so that the vegetables on the drying net 51 are turned back and forth during the drying process, further ensuring the effect of evenly drying the vegetables on the drying net 51.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
