Triglycidyl isocyanurate dry powder extruding and pelletizing production line and triglycidyl isocyanurate dry powder extruding and pelletizing production technology

Abstract

The invention relates to a triglycidyl isocyanurate dry powder extruding and pelletizing production line and a triglycidyl isocyanurate dry powder extruding and pelletizing production technology. The triglycidyl isocyanurate dry powder extrucing and pelletizing production line is characterized by comprising a vibration dryer, a condenser connected with the gas outlet of the vibration dryer, a solvent recycling tank and a gas draught fan I which are sequentially connected with the condenser, a dry powder cyclone separator and a dry powder tank which are connected with the material outlet of the vibration dryer as well as a material extruder, a tablet machine, a band-type cooling conveyor, a pulverizer, a screening machine and a packaging machine which are sequentially connected with the discharge hole of the dry powder tank. The triglycidyl isocyanurate dry powder extruding and pelletizing production technology comprises a drying moist material, carrying out cyclone separation on a dry powder material, performing melt extrusion, tabletting, cooling on the band type cooling conveyor, pulverizing, screening and packaging. The triglycidyl isocyanurate dry powder extruding and pelletizing production line and the triglycidyl isocyanurate dry powder extruding and pelletizing production technology have the advantages that a volatile organic solvent is effectively recycled, environmental pollution is reduced, the operating environment in a production process is improved, and the environmental problem is solved; meanwhile, the density of the triglycidyl isocyanurate dry powder product is medorate and is about 1.32g/cm<3> generally, so that the hardness of the triglycidyl isocyanurate dry powder product is maintained, and the triglycidyl isocyanurate dry powder product can be easily pulverized and dispersed when being used by a user.

Description

technical field [0001] The invention belongs to the technical field of triglycidyl isocyanurate granulation, in particular to a triglycidyl isocyanurate dry powder extrusion granulation production line and a production process. Background technique [0002] Triglycidyl isocyanurate is irritating to human skin. In order to prevent its dust from falling on human skin, it is usually made into granules at home and abroad. [0003] At present, there are two production processes for the production of triglycidyl isocyanurate, one is the wet granulation production process, which is to extrude and granulate the material containing organic solvent (25-30%) with an extrusion granulator , and then put the material in an oven for drying. The advantage of the wet granulation process is that the product particles are uniform and the density is small (1.25g / cm 3 ), the product is relatively loose and easy to disperse when used by the user, but a large amount of organic solvents volatilize...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two production processes for the production of triglycidyl isocyanurate, one is wet granulation production process, which will contain organic solvent (25-30 %) of the material is extruded and granulated by an extrusion granulator, and then dried in an oven. The advantage of the wet granulation process is that the product particles are uniform and the density is small (1.25g/cm3), the product is relatively loose and easy to disperse when used by users, but a large amount of organic solvents volatilize into the air during the drying process of the wet granulation production process, which not only pollutes the environment, endangers the physical and mental health of workers, but also wastes energy.
