Detailed ways

Technical scheme of the present utility model: referring to Fig. 1 to Fig. 4, a drum dryer includes a drum, a rolling drive device, and a drying device, and the rolling drive device includes a motor 1, a driving gear (not marked in the drawings) and a chain (attached Not shown in the figure), the motor 1 is connected to the drive gear; the drum includes a cylinder 2 and a helical blade 6, a number of air holes 3 are evenly arranged on the cylinder 2, and a circle of driven gear 13 is arranged around the cylinder 2 on the outer wall of the middle part of the cylinder 2 ; The driving gear and the driven gear 13 are connected by a chain, and the driving gear and the driven gear 13 move relatively to drive the drum to rotate. The drying device includes an air delivery pipe 8 arranged in the middle of the cylinder body 2 and a blower 14 connected to the air delivery pipe 8 , and several vents 12 are arranged on the air delivery pipe 8 . The wind blown by the blower 14 blows to the rotating product through the vent 12, so that the moisture on the surface of the product evaporates to achieve the purpose of drying, and the rotation of the drum makes the drying more uniform, preventing the surface from being dry or even scorched when the bottom is wet when the pile is dry.

In order to prevent the operator from being scalded by the gas ejected from the vent hole 3, a protective cover 9 is provided outside the cylinder body 2. The protective cover 9 is buckled and connected to the bracket 15, and the bracket 15 supports the roller. The protective cover 9 can be opened or removed for easy maintenance. An exhaust port 11 is provided above the protective cover 9, a drain port 10 is provided below, and a collection tank is provided below the drain port 10. Part of the gas ejected from the vent hole 3 condenses with the cylinder 2 and flows out along the drain port 10, and part of it flows out from the exhaust port. 11 Exhausted in gaseous form.

In order to prevent uneven cleaning and drying due to product accumulation, the spiral blade 6 spirally extends from one end of the cylinder 2 to the other end of the cylinder 2 to form the feed port 4 and the discharge port 5 of the dryer. A partition 7 with the same height as the width of the helical blade 6 is arranged between the blades 6, and the angle between the plane of the partition 7 and the radius of the cylinder 2 is 45-60°. The rotation angle of the helical blade 6 is 45-60°.

Both the feed port 4 and the discharge port 5 are closed structures, that is, the diameter of the cylinder body 2 gradually decreases from the cylinder body to the mouth end, and is in the shape of a trapezoidal thin-walled cylinder. The feed port 4 is connected to the feed conveyor belt, and the discharge port 5 is connected to the discharge conveyor belt. Fully automatic continuous drying without manual feeding.

In an embodiment of the present invention, the blower 14 is provided with a temperature controller for adjusting the temperature of the air blown out by the blower 14 . The temperature of the air blower 14 can be set according to the different types of products or the degree of drying of the products, so as to speed up the drying speed while ensuring the drying effect.

The work process of the utility model: the product to be dried enters the feed port 4 through the feed conveyor belt, the drum dryer is started, the product is turned over in the drum, the blower 14 is started and adjusted to the required temperature, and the product is During the rotation of the drum, it starts to dry under the action of hot air. The wind blown by the blower 14 is blown onto the product from the vent 12 of the air pipe 8. The product moves forward with the helical blade 6. The helical blade 6 has a certain inclination angle, which improves the product. The degree of tumbling is improved, and the drying is more thorough, and the partition 7 between the spiral blades 6 in the middle of the drum can also prevent the product from accumulating between the spiral blades 6, making the product dry unevenly. After drying, the product falls onto the discharge conveyor belt through the discharge port 5, and is transported to the next process by the discharge conveyor belt for further processing.
