First, technical objectives (product output, quality and process requirements, etc.):
(1) technical parameters:
One point oneName of drying material: Granulation of ceramic materials20200 M）
One point twoSolid content : 50%-60%About
One point threeMaximum moisture evaporation: 5-8kg/h(large scale production equipment can be customized)
One point fourIntake air temperature: 120-280℃ Air temperature: 75-145℃
One point fiveHeating method: Electric heating (electric heating power)20kw）
One point sixDischarging mode: The bottom discharge particles of a cyclone separator material, Gabriel bag filter material
One point sevenDrying chamber diameterXhigh 1300*1600
One point eightTotal height of drying tower: aboutTwo point three fiverice
One point nineTotal mechanical power: aboutTwenty-fiveKW
One point one zeroAtomizing form: Air flow prilling nozzle
One point one oneSelection of bag dust collector
Two, technical design (process design, equipment layout, control design)
1) process node
1.Feeding system: the liquid material is pumped to the prilling nozzle by the pump.
2.Granulation spray system: from the spray nozzle atomized liquid droplets into micron size, into the dry tower.
ThreeHeating system: it is composed of electric heater and hot air pipe to complete the heating of atmospheric pressure to the high temperature air needed by process.
4.Drying tower system:The utility model is composed of a drying tower body, a hot air distributor, a spiral case, an illuminating lamp, an observation door, etc.
5.Product delivery and dust removal: cyclone separator, bottom collection bottle, tail bag dust collector three points collection
6.Electrical control system: embedded touch control system
Two) system technology expounded
After the pretreatment of the process, the feed liquid enters the screw pump to the drying tower at the bottom of the granulation atomizer. The nozzle uniformly atomized the material into micron droplets and entered the tower. Atmospheric air enters the heating system is required to process the heating temperature, the hot air duct, hot air volute, hot air distributor evenly into the upper drying tower, and the droplets contact after high temperature curing, pyrolysis product, finished product after drying with exhaust by the air outlet pipe to the cyclone separator gas solid separation
