Large-particle compound fertilizer granulating and forming device

Abstract

The invention relates to the technical field of granulation equipment, in particular to a large-particle compound fertilizer granulating and forming device. The device comprises a feeding cylinder body, and a plurality of discharging holes are formed in the surface of the feeding cylinder body; a stator is arranged in the feeding cylinder body; a material channel is formed in the stator; a first stirring screw rod is horizontally and rotatably arranged in the material channel; a feeding hole is formed in one end of the stator, and a discharging hole is formed in the other end; a feeding pipeline used for conveying molten materials into the material channel is arranged at the feeding hole; and the discharging hole is a rectangular cavity, and an equalizer is arranged in the rectangular cavity. The problems as follow are solved: when a material radial channel is blocked, insufficient yield, non-uniform material distribution and non-uniform material appearance are caused, and shutdown fordisassembly and cleaning is needed; and non-uniform material distribution and yield reduction are caused and shutdown for disassembly and cleaning is needed due to blockage of radial small holes in the equalizer caused by easy generation of sediments in the process of feeding molten materials into the equalizer for discharging.

Description

technical field [0001] The invention relates to the technical field of granulation equipment, in particular to a large-grain compound fertilizer granulation forming device. Background technique [0002] After the molten material enters the granulation equipment, when the molten material enters the material channel inside the feeding cylinder, the suspended solids in the molten material tend to precipitate and accumulate at the bottom of the material channel. After a period of production, the material radial channel It will be blocked, resulting in insufficient output, uneven material distribution, and uneven material shape. It must be stopped for disassembly and cleaning. This process takes 3 to 4 hours, resulting in great economic losses and environmental pollution. In addition, when the molten material enters the equalizer During the discharge process, the molten material will also easily produce sediment, which will block the radial holes in the equalizer, resulting in un...

AI Technical Summary

Problems solved by technology

[0004] Solve the problem that the radial channel of the material will be blocked, resulting in insufficient output, uneven material distribution, and uneven material shape. It must be stopped for disassembly and cleaning, and when the molten material enters the equalizer for discharge, the molten material will also easily produce sediment. , so as to block the radial holes in the equalizer, resulting in uneven distribution of materials, reduced output, and the need to stop the machine for disassembly and cleaning. A large-grain compound fertilizer granulation molding device is provided.
