Combined-type granulator

Abstract

The invention belongs to a wet material granulation principle and an equipment combination process, and particularly relates to a combined-type granulator. The combined-type granulator comprises a plurality of layers of combined box bodies, a temporary storage feed bin and a plurality of layers and groups of roller mills. Each group of roller mills is equipped with a rotary joint, a cleaning blade, an elastic stripping frame, a material baffle and a guide plate; a waste gas emptying interface is also arranged on each of the box bodies, and an air inlet at a lowest layer of the granulator is arranged on a bracket. The linear velocity of a tooth surface and the flow rate of volume of a rotary drum of each of the roller mills at a second layer are higher than those of a rotary drum of each of the roller mills at a first layer, and the linear velocity of a tooth surface and the flow rate of volume of a rotary drum with a reticular tooth socket or a single radial tooth socket of each of the roller mills at an adjacent lower layer are designed according to the volume properties of materials in the area. According to the granulator disclosed by the invention, hard foreign matters can be stripped, and simple granulation of soft materials in a cream state, a paste state, a slurry state and the like can be realized; meanwhile, caky and blocky materials can be pulled into monomer granules, soft and hard materials can simultaneously enter into the granulator, and granules at an outlet have a plurality of pores and are in an irregular shape.

Description

technical field [0001] The present invention mainly belongs to the principle of wet material granulation and equipment combination process, especially relates to a combined granulator using a mesh tooth surface rolling machine for heating as a unit. The combined granulator can be used for high-humidity materials, slurry , paste, paste, cake, block materials, especially suitable for granulation and drying of the above-mentioned mixed materials; used in environmental protection, metallurgy, light industry, chemical industry, food, medicine, feed, agriculture (forestry, animal husbandry, Fishery) industry product processing and other fields, granulate and dry (dry) the paste, paste, slurry, cake, bar, and block materials with high water content. The combined granulator of the present invention can also Municipal and industrial sludge are granulated and desiccated (dried). Background technique [0002] With the continuous emergence of new materials (raw materials), the requirem...

Problems solved by technology

Sometimes it will directly enter the granulation system in the form of a thin paste. Such a thin paste material will flow directly to the bottom without contacting the heat exchange surface in the gap between the two rolling drums of the granulator and cause blockage, which will seriously affect functioning normally, and the cleanup is very heavy
