Example two
As shown in fig. 2 to 4, the present embodiment is a material drying and conveying device designed based on the first embodiment. The material drying and conveying device comprises a heating part 1, a drying cylinder 2, a belt conveyor 3 and a rotary cooling cylinder 4.
The heating part 1 and the drying drum 2 are described in detail in the first embodiment, and are not described herein again. First silo 26 is fixedly mounted below discharge port 231 of drying cylinder 2, and first silo 26 is made of iron plate or plastic material, is in a U-shaped long strip structure, and forms a certain included angle with discharge port 231.
A belt conveyor 3 is fixedly arranged on the right side of the drying cylinder 2, and a rotary cooling cylinder 4 is fixedly arranged on the right side of the belt conveyor 3.
The belt conveyor 3 is of a zigzag structure, the structure of the rotary cooling cylinder 4 is similar to that of the drying cylinder 2, the rotary cooling cylinder also comprises a cooling cylinder body 40, a cooling cylinder supporting roller frame 41, a rotary driving mechanism, a cooling cylinder upper cover 42, a cooling cylinder feeding port 43 and the like, and blades are also fixedly arranged on the inner wall of the cooling cylinder body 40. The cooling cylinder support roller frame 41 rotatably supports the cooling cylinder 40; the rotary driving mechanism is rotationally connected with the cooling cylinder 40 and provides torque for the cooling cylinder; the upper end of the cooling cylinder body 40 is fixedly provided with a cooling cylinder upper cover 42, and the cooling cylinder upper cover 42 is provided with a cooling cylinder feeding port 43.
One end of a conveying belt on the belt conveyor 3 is positioned below one end of the first trough 26, and the other end of the conveying belt is positioned above and to the left of the cooling cylinder feeding port 43. A second trough 30 is fixedly arranged below the other end of the conveying belt, and the end part of the second trough 30 extends into a feeding hole 43 of the cooling cylinder.
The belt conveyor 3 adopts a common conveyor with a V-shaped or U-shaped cross section on the market, is provided with a power device in a matching way, and can work only by being connected with a power supply according to requirements.
In operation, the drying cylinder 2 is first preheated as described in the first embodiment, and when the temperature reaches a predetermined value, the material is slowly fed from the feeding chute 25, and the cylinder 20 is rotated and heated for drying. Since the barrel 20 is inclined at an angle to the ground, the material slowly moves toward the bottom end and is transferred into the first trough 26 from the discharge port 231. After the material has been transferred into the first chute 26, the material slides under gravity onto the belt of the belt conveyor 3, since it is also inclined. The belt of the belt conveyor 3 carries the material up and over to the top and then falls into the second chute 30, as the second chute 30 is also inclined, the material slides into the second chute 30. After the material gets into cooling barrel 40, because the structure of rotatory cooling cylinder 4 is unanimous with stoving section of thick bamboo 2, only does not have the heating function, the material is rotatory, is rolled, is raised etc. under the effect of blade and barrel, finally reaches quick heat dissipation purpose. When the material reaches the end of the cooling cylinder 40, the temperature has dropped to the point where packaging or further processing can take place.
When drying and cooling the material that the granule is less, because its granule is little, raise dust appears easily, consequently can seal band conveyer 3. The specific scheme is as follows: a U-shaped cover made of organic glass or iron sheet is arranged on the upper belt of the belt conveyor 3, and the cover and the belt conveyor 3 are matched in shape, so that dust can be well inhibited.
The utility model discloses area occupied is little, compact structure, and work efficiency is high.
