Detailed Description
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a vertical cylindrical first shell 1, a feeding cylinder 2 coaxial with the first shell 1 is arranged at the upper end of the first shell 1, the lower end of the first shell 1 is conical, and a discharge hole 3 is arranged at the lower end of the first shell 1; a cylindrical second shell 4 coaxial with the first shell is arranged in the first shell 1, fine ventilation holes are formed in the side wall of the second shell 4, a plurality of spiral blades 5 which are uniformly distributed in the circumferential direction are arranged on the outer circular surface of the second shell 4, the outer edge surface of each spiral blade 5 is in contact with the side wall of the first shell 1, and an annular channel is formed between every two adjacent spiral blades 5; dry and cold air is introduced into the lower end of the second shell 4.
In order to fix the second housing 4, the first housing 1 and the second housing 4 are fixed together via a plurality of connecting rods 6.
In order to realize that compound fertilizer particles can evenly and can get into the annular passage fast, second casing 4 upper end have a toper protruding piece 7, have a plurality of and a plurality of helical blade 5 one-to-one's baffle 10 on the outer disc of protruding piece 7, baffle 10 cuts apart into even many with protruding piece 7 outer conical surface.
The lower end of the second shell 4 is provided with a horizontal air inlet pipe 8, and one end of the air inlet pipe 8 penetrates through the side wall of the first shell 1 and is arranged outside the first shell 1.
In order to realize convenient discharging, the lower end of the first shell 1 is provided with a horizontal bottom plate, and the bottom plate and the first shell 1 are fixed together through a plurality of support rods.
In order to accelerate the air drying efficiency, the spiral blade 5 is made of a filter screen.
