The dry powder spray granulation device has the characteristics of simple process, low comprehensive cost, high granulation rate, uniform granularity, high output, energy saving, environment protection and the like and is easy to realize, and thus, the dry powder spray granulation device has scientificity, technicality, reliability and economy and can ensure a manufacturer to obtain a product meeting the requirements with low investment so as to obtain a novel economic growth point.
Description
Technical field
The utility model relates to a kind of dry powder spray granulation plant.
Background technology
Existing traditional prilling method mainly contains pressure comminution granulation and liquid slurry spray granulation.
The pressure comminution granulation mainly adopts tablet press machine, roll squeezer, roller press, screw extruder equal pressure Granulation Equipments, by suppressing the oven dry of granulation, tunnel type, has obtained certain success aspect the relatively large particle producing.But this technology is used to produce 0.5～2 millimeter-sized particles than difficulty, and very low to those water capacities, granularity is very thin, internal friction is little, to carry out the pressure application granulation also be difficulty to the powder material of good fluidity, not only power consumption is big, and granulating rate is low, and single machine yield is low.
The liquid slurry liquid that spray granulation adopted slurry mist projection granulating equipment has press atomization granulating and drying machine and centrifugal spray granulation drying machine, mainly be to make slip and then mist projection granulating by ball mill, and it is air-dry dry to obtain heat-flash by burning gases or fuel oil.This technology need consume great lot of water resources when producing slip, adopt the air-dry dry meeting of heat-flash to discharge a large amount of hot gas, causes energy waste, and produces flue dust and CO simultaneously
2, CO, SO
2Deng toxic gas, environment is polluted.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art part, provide a kind of simple in structure, integrated cost is lower, the dry powder spray granulation plant of convenient operating maintenance.
For achieving the above object, the utility model adopts following technical scheme: a kind of dry powder spray granulation plant comprises: the dry powder sponging granulator, in order to micro mist is carried out are dried to particulate material in dry method centrifugal granulating and early stage; And microwave dryer, in order to particulate material is carried out later stage rapid draing.
As preferably, described microwave dryer is the tunnel type micro wave drying machine.
Further, be provided with the powder conveyer belt between described dry powder sponging granulator and the microwave dryer.
Further, the material inlet of described dry powder sponging granulator is connected with a feeding device.Described feeding device preferably is made up of hopper and screw conveying device.
The utlity model has that technology is simple, characteristics such as lower, the easy realization of integrated cost, granulating rate height, epigranular, output height and energy-conserving and environment-protective, therefore have science, technical, reliability and economy, can allow the low investment of manufacturer also can obtain satisfactory product, thereby obtain new growth engines.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure:
10-dry powder sponging granulator; The 11-atomization chamber; 12-high-pressure fog mouth; 13-umbrella shape rotating disk; The 14-spray tower; 15-infrared ray heating plate; 20-tunnel type micro wave drying machine; 30-powder conveyer belt; The 41-hopper; The 42-screw conveying device.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
The specific embodiment
As shown in Figure 1: dry powder spray granulation plant described in the utility model, mainly form by dry powder sponging granulator 10, tunnel type micro wave drying machine 20 and feeding device.Wherein, between dry powder sponging granulator 10 and tunnel type micro wave drying machine 20, be provided with powder conveyer belt 30; Feeding device is made up of hopper 41 and screw conveying device 42.
The course of work of the present utility model is as follows:
Micro mist in the hopper 41 is sent into the spraying chamber 11 of dry powder sponging granulator 10 by screw conveying device 42, and the amount of sending into of micro mist is regulated by the rotating speed of Frequency Converter Control screw conveying device 42; Feeding compressed air simultaneously in spraying chamber 11 dispels micro mist.The atomized water that micro mist and the high-pressure fog mouth 12 in spraying chamber of flying out sprays combines and condenses, drop on the umbrella shape rotating disk 13, umbrella shape rotating disk 13 rotation at a high speed (can by frequency control) makes micro mist carry out centrifugal granulating in spray tower 14, the particle that falls is through infrared ray heating plate 15 direct-fired high temperature drying air sections, the discharging opening of spray tower bottom is fallen at last by rapid draing (being called the heated-air drying in early stage) in the particle top layer.Bottom at spray tower feeds dry air, keeps spray tower 14 bottom air dryings, simultaneously the water vapour on spray tower 14 upper stratas is discharged.The particulate material that also there is not bone dry is after the tower bottom of spraying comes out, in powder conveyer belt 30 is conveyed into tunnel type micro wave drying machine 20.In microwave dryer, particulate material heated by microwave rapid draing (being called later stage microwave drying), and the water content of control particulate material is in effective range; , by the blower fan input air water vapour in the drying machine is discharged at the microwave drying drive end unit.Be transported at last in the powder deposit storehouse from the particulate material that microwave dryer comes out and store.
The described dry powder spray granulation plant of present embodiment has following characteristics:
1, adopting the dry powder mist projection granulating, is to spray dried micro mist and atomized water simultaneously in spray tower, only need use the water of powder water content about 20%, and the water yield of dry evaporation is little; Only add dry air in a small amount, the heat of discharge is little; Adopt infrared ray directly to heat, no pernicious gas produces, both energy savings, environmental protection again.
2, the tunnel type micro wave drying is compared with burning gases or fuel oil drying, and microwave drying is even, speed is fast, energy savings, and no pernicious gas produces.
3, heated-air drying is fast to surperficial rate of drying, can take away water vapour fast, but wasted heat is big, and the volume drying time is long.And microwave drying is even to volume drying, speed is fast, energy-conservation, easy to control, but the particle surface drying is wanted slow with respect to hot blast, also need to increase throughput and take away water vapour.Therefore adopt the classification drying, be the infrared ray heated-air drying early stage, to particle surface rapid draing, and can be with a large amount of water vapours in the spray tower; Later stage is microwave drying, energy rapid draing, and uniform drying, and energy savings, fair like this branch utilizes the advantage of hot blast and microwave drying, avoids their deficiency.
