Example 3

[0034] As Figures 1 to 7 shown:

[0035] Further, the drying box 2 further comprises an outer shell 15, a drying conveying belt, an air inlet pipe 16, and a pushing mechanism 17, the drying conveying belt is arranged inside the outer shell 15, the air inlet pipe 16 is arranged on the left side of the outer shell 15, and the pushing mechanism 17 is arranged below the drying conveying belt;

[0036] Further, the drying conveying belt further comprises a conveying belt device 18, a drying belt 19, a protrusion 20, and an air hole 21, the drying belt 19 is arranged inside the conveying belt device 18, the protrusion 20 is arranged on the surface of the drying belt 19, and the air hole 21 is arranged on the surface of the drying belt 19 and the protrusion 20;

[0037] Further, the pushing mechanism 17 further comprises a transmission wheel 22, a cylinder 23, an inclined groove 24, a circular ring 25, a sliding block 26, a connecting rod 27, a pushing plate 28, and a limiting block 29. The transmission wheel 22 is arranged at the rear side of the driving motor b30 of the conveying belt device 18. The cylinder 23 is arranged below the transmission wheel 22 and is connected with the transmission wheel 22 through a transmission belt. The surface of the cylinder 23 is provided with an annular inclined groove 24. The circular ring 25 is arranged at the outer side of the inclined groove 24. The sliding block 26 is arranged at the inner side of the circular ring 25 and is slidingly connected with the sliding groove. The connecting rod 27 is hingedly connected at the left side of the circular ring 25. The connecting rod 27 is provided with a sliding groove at the left side. The pushing plate is obliquely arranged in the inside of the shell 15. The left and right ends and the front and back sides of the pushing plate 28 are slidingly connected with the groove in the inside of the shell 15. The sliding groove on the connecting rod 27 is slidingly connected with the limiting block 29 at the left end of the front side of the pushing plate 28.

[0038] Further, the pushing plate 28 is provided with a hole with a smaller diameter than the air hole 21.

[0039] When the barrel cover 10 of the feeding cylinder 9 is closed, the operator controls the air supply through the air inlet pipe 16 to the drying box 2 through the workshop controller. After the hot air passes through the hole of the pushing plate 28, the airflow becomes uniform, and the hot air is blown upward through the air holes 21 on the drying belt 19 and the protrusions 20 to clean the drying materials. The drying belt 19 and the protrusions 20 can be made of hard rubber material that can withstand high temperature, which ensures that the drying materials are carried without affecting the function of the conveying belt. Then, the hot air containing water vapor is discharged through the collecting hopper 4. The materials are pushed onto the drying belt 19 by the feeding mechanism. The drying belt 19 is driven by the conveying belt device 18 to move to the right. The materials fall onto the drying belt 19 and the protrusions 20 of the drying belt 19. The hot air blows upward to dry the materials. Then, the materials fall onto the pushing plate 28 to the right. This drying method increases the drying area and prevents the materials from being crushed to produce debris, which ensures the drying effect.

[0040] The pushing plate 28 is connected with the conveying belt device 18 through the transmission wheel 22. When the conveying belt device 18 operates, the transmission wheel 22 drives the cylinder 23 to rotate, which drives the sliding block 26 to slide on the inclined groove 24. The rotary motion is converted into the forward and backward reciprocating motion of the circular ring 25. The circular ring 25 drives the connecting rod 27 to swing, which drives the limiting block 29 to make the pushing plate 28 slide left and right in the shell 15. The drying materials are pushed to the right into the collecting box 3. During the drying process, small materials fall from the air holes 21. Because the diameter of the hole of the pushing plate 28 is smaller than the diameter of the air hole 21, and the hot air is blown, these small materials can also be dried and pushed into the collecting box 3. The hot air containing water vapor is sent upward in time after drying, which can separate the dried materials from the water vapor in time, prevent the water vapor from condensing to form water in the device, improve the drying efficiency of the device, and reduce the equipment maintenance problems caused by water accumulation.

[0041] In summary, the device is provided with a feeding device 1, a drying box 2, a material collecting box 3, through the drying method of hot air and material vertical blowing, preventing the generation of difficult-to-recover debris in the repeated stirring process of the material, ensuring the drying effect; at the same time, the material is discharged into the material collecting box 3 in time after drying, and the water vapor after drying is discharged after recycling waste heat through the water vapor recycling device, improving the drying efficiency of the device, reducing the equipment maintenance problems caused by accumulated water, recycling the waste heat in the hot air, and improving the thermal efficiency of the device.

[0044] After the barrel cover 10 of the feeding cylinder 9 is closed, the operator controls the air supply setting to deliver hot air to the drying box 2 through the air inlet pipe 16 through the workshop controller; after the hot air passes through the holes of the push plate 28, the airflow becomes uniform; the drying belt 19 and the protrusion 20 can be made of hard rubber material resistant to high temperature, so that the drying material can be carried without affecting the function of the conveying belt; then the hot air containing water vapor is discharged through the collecting hopper 4, the material is pushed onto the drying belt 19 through the feeding mechanism, the drying belt 19 is driven to run to the right under the driving of the conveying belt device 18, the material falls onto the drying belt 19 and the protrusion 20 of the drying belt 19, the hot air blows and dries from bottom to top, and then falls onto the push plate 28 to the right; this drying method increases the drying area and is not easy to cause the material to be pressed to generate debris, so that the drying effect is ensured;

[0045] The push plate 28 is connected to the conveying belt device 18 through the transmission wheel 22; when the conveying belt device 18 operates, the transmission wheel 22 drives the cylinder 23 to rotate, the driving sliding block 26 slides on the inclined chute 24 to convert the rotary motion into the forward and backward reciprocating motion of the circular ring 25, the circular ring 25 drives the connecting rod 27 to swing, the connecting rod 27 drives the limiting block 29 to make the push plate 28 slide left and right in the outer shell 15, the dried material is pushed into the material collecting box 3 to the right, and the fine material falls from the air hole 21 during the drying process; since the diameter of the hole of the push plate 28 is smaller than that of the air hole 21, and the hot air blows, the fine material can also be dried and pushed into the material collecting box 3;

[0046] The hot air carrying water vapor is pushed into the condenser 6 by the collector 4 through the fan 5, and the hot air in the collecting box 3 is introduced from the bypass air pipe 7 during the process. The hot air is discharged after recovering the waste heat in the condenser 6, the generated condensed water is discharged into the water tank through the drain pipe 8, the hot air carrying water vapor after drying is sent out upward in time, so that the dried material and water vapor can be separated in time to prevent water vapor from condensing in the device to produce accumulated water, improve the drying efficiency of the device, reduce the equipment maintenance problem caused by accumulated water, recover the waste heat in the hot air, and improve the thermal efficiency of the device.
