[0002] A dryer is a mechanical device that uses heat to vaporize the moisture (generally water or other volatile liquid components) in the material to obtain solid materials with a specified moisture content. It is a mechanical device that realizes the material drying process.

[0003] The Chinese patent with patent number CN202322092941.X discloses "A granulation and drying device". When the auger drives the fertilizer to be transported, the fertilizer is dried by hot air blowers arranged on both sides to improve the air drying efficiency, so that no moisture remains in the fertilizer, and the vibrating discharge plate is used to effectively avoid fertilizer blockage.

The left end of the right base is fixed to the left base, and an air inlet hole is provided inside the right base. The mounting plate and the right base are respectively locked and fixed to the assembly by bolts.

[0009] It is further preferred that the cross-section of the air inlet is funnel-shaped, with a large cross-section at the right end and a small cross-section at the left end, so that after the hot air blower at the right end outputs hot air, it can directly flow into the large air inlet at the right end over a large area, and through the effect of the funnel shape, the hot air enters the drying barrel at a high air flow rate, which can quickly dry the granular material and improve the drying efficiency.

[0014] It is further preferred that the guide plate is made of stainless steel, which has high strength and is resistant to support.

DETAILED DESCRIPTION

[0026] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0027] See also Figure 1-2 The utility model provides a granulation drying device, including an assembly 1, a drying chamber 2, a feed hopper 4, a motor 5, an auger 6, an air outlet plate 7, and a hot air blower 8. The upper end of the assembly 1 is provided with the drying chamber 2, and the feed hopper 4 is fixed to the top thereof. The motor 5 is installed inside the assembly 1, and the bottom end thereof is connected to the auger 6 by a coupling. The left end of the assembly 1 is provided with the air outlet plate 7, and the hot air blower 8 is installed at the right end of the assembly 1.

[0028] See also Figure 3-4The utility model provides a granulating and drying device, wherein a cooling device 3 is fixed to the bottom end of an assembly body 1, and the cooling device 3 comprises a base body 31, a guide plate 32, a cooling fan 33, a connecting pipe 34, a conveying pipe 35, a connecting air pipe 36, an air nozzle 37, an anti-slip strip 38, a drying barrel 39, an exhaust fan 310, and a discharge pipe 311. The top end of the base body 31 is fixed to the assembly body 1, the top end of the guide plate 32 is fixed to the base body 31, the cooling fan 33 is installed at the right end of the base body 31, the bottom end of the connecting pipe 34 is connected to the cooling fan 33, and the left end thereof is connected to the conveying pipe 35, the conveying pipe 35 is installed inside the bottom end of the base body 31, and the top end thereof is connected to the connecting air pipe 36, the top end of the connecting air pipe 36 is installed with an air nozzle 37, the top end of the drying barrel 39 is fixed to the assembly body 1, the exhaust fan 310 is installed at the left end of the base body 31, and the discharge pipe 311 is installed at the left end of the base body 31.

[0029] In this embodiment, the bottom end of the guide plate 32 is hollow, which is convenient for the heat dissipation of the granular material during the process of being input into the interior of the matrix 31, thereby increasing the heat dissipation time of the granular material and improving the heat dissipation efficiency. The guiding effect of the guide plate 32 allows the granular material to remain from the right end of the matrix 31, thereby increasing the output path length of the granular material. The granular material rolls inside the matrix 31 to fully dissipate the heat and improve the heat dissipation efficiency. An anti-slip strip 38 is bonded to the bottom end of the interior of the matrix 31 to block the downward sliding output of the granular material, so that it is slowly output inside the matrix 1 and dissipates the heat sufficiently, thereby avoiding the situation where the granular material still carries hot air after being output and avoiding the situation where the granular material regains moisture. The guide plate 32 is made of stainless steel, which is strong and resistant to support. The anti-slip strip 38 is made of composite plastic, which is practical and hard in texture.

[0030] See also Figure 5-6 The utility model provides a granulation drying device, the drying barrel 39 includes a left base 391, a discharge port 392, a mounting plate 393, a right base 394, and an air inlet 395. The top of the left base 391 is fixed with a mounting plate 393, and the bottom of the left base 391 is provided with a discharge port 392, the bottom end of the discharge port 392 is connected with the base 31, the left end of the right base 394 is fixed with the left base 391, the inside of the right base 394 is provided with an air inlet 395, and the mounting plate 393 and the right base 394 are respectively locked and fixed with the assembly 1 by bolts.

[0031] In this embodiment, the cross-section of the air inlet 395 is funnel-shaped, with a large cross-section at the right end and a small cross-section at the left end. This facilitates the hot air to flow directly into the large air inlet 395 at the right end after the hot air blower 8 at the right end outputs the hot air. The funnel-shaped effect allows the hot air to enter the drying barrel 39 at a high air flow rate. By blowing in hot air at a high flow rate, the particulate material can be dried quickly and the drying efficiency can be improved. The cross-section of the right side substrate 394 is rectangular, and a semicircular channel is provided inside the left end to facilitate the input of hot air, so that it fills the interior of the drying barrel 39 and fully and completely dries the particulate material. The surface of the left side substrate 391 is provided with filter holes to facilitate the output of hot air.

[0032] See also Figure 1-Figure 6 When in use, a small amount of processed granular material is put into the hopper 4, so that the material enters the drying barrel 39, and the motor 5 drives the auger 6 to rotate, so that the material moves on the auger 6. At the same time, the hot air blown by the hot air blower 8 flows into the drying barrel 39 at a high speed through the air inlet hole 395, and the granular material is quickly dried, so that the dried material flows into the interior of the base 31 from the discharge port 392;

[0033] Under the action of the guide plate 32, the material flows into the right end of the base 31 and rolls downward. During the rolling process, it is affected by the anti-slip strip 38 and the rolling is retained, which increases the time for the granular material to dissipate heat inside the base 31. Dry cool air is blown in by the air cooler 33, input into the conveying pipe 35, and sprayed out through the air nozzle 37, so as to fully dissipate the heat of the granular material. After the material has dissipated the heat, it is discharged through the discharge pipe 311. Among them, the exhaust fan 310 is used to accelerate the discharge of the wind mixed with hot air inside, so as to improve the heat dissipation effect.
