Description
Technical field
The present invention relates to the technical field of drying machinery, especially refer to microwave and electromagnetic heat source convection current combined belt type drier.
Background technology
Convective drying refers to that heat transfer type take convection heat transfer' heat-transfer by convection as main drying mode.Such drier is a lot, as belt dryer, pneumatic conveyer dryer, flash distillation dryer, spray dryer, fluidized bed dryer and baking oven etc.Their common features are to using air as drying medium thermophore, contact carry out heat transmission with wet stock, and transfer mode be take convection current transmission as main.After the temperature of wet stock raises, hygroscopic water wherein will become steam to be taken away by air, i.e. mass transport process.Wet stock can reach dry object after overheated, matter transmission.
Investment and the Operation cost comparison of microwave drying are high, so also uneconomical as unique energy with heating using microwave, particularly, when material moisture content is very high, the energy-conservation advantage of micro-wave drying is just not remarkable.When the moisture content of material approaches or reaches critical point, the efficiency of convection heat transfer' heat-transfer by convection is just more and more lower, and rate of drying is also just more and more slower, if now material is imposed to microwave energy, will make rate of drying be increased sharply.
The current domestic combining form about microwave and conventional drying device, mostly be micro-wave vacuum equipment, this is a kind of more effective combining form for vacuum desiccator by microwave, obtains users' approval, the market sales volume, rising year by year, has been widely used in pharmacy and food industry.But for the combination of microwave and convective drying, particularly the moisture bright material of height is carried out to dry microwave and the combination of convective drying, but have no report.
Summary of the invention
Microwave of the present invention and electromagnetic heat source convection current combined belt type drier, the object of employing.
To achieve these goals, technical solution of the present invention is: microwave and electromagnetic heat source convection current combined belt type drier are comprised of feed hopper, uniform distributor, great-power electromagnetic heater, exhaust blower, microwave storehouse, microwave magnetron generator, body, small power electromagnetic heater, driving-belt, discharging Live roller, motor, speed changer, discharging power bin section, falling-rate periods of drying chamber section, air inlet, Micro-wave convection drying chamber section, electromagnetism constant rate of drying chamber section, stand leg, conveyer belt, charging Live roller; Body is connected and is combined by electromagnetism constant rate of drying chamber section, Micro-wave convection drying chamber section, falling-rate periods of drying chamber section and discharging power bin section.
Body upper of the present invention arranges the microwave storehouse with exhaust blower, is provided with microwave magnetron generator in microwave storehouse; Body one side arranges charging Live roller, opposite side arranges discharging Live roller, and charging Live roller is connected by conveyer belt with discharging Live roller; Charging Live roller top arranges the feed hopper with uniform distributor; Electromagnetism constant rate of drying chamber section internal upper part arranges great-power electromagnetic heater, bottom arranges air inlet; Section top, Micro-wave convection drying chamber is connected with microwave storehouse, bottom is provided with air inlet; Falling-rate periods of drying chamber section internal upper part arranges small power electromagnetic heater; In discharging power bin section, bottom arranges the speed changer of translator, and speed changer is connected with charging Live roller by driving-belt.
Electromagnetism constant rate of drying of the present invention chamber section is the first dryer section, material moisture content in this section is higher, and mostly be surperficial free moisture, the convection current that the high-temperature hot-air of this section of abundant sharp great-power electromagnetic heater generation forms, for constant speed drying section, when the moisture content of material approaches or reaches critical point, the efficiency of convection heat transfer' heat-transfer by convection is just more and more lower, rate of drying is also just more and more slower, and now material just enters Micro-wave convection drying chamber section.
Micro-wave convection drying of the present invention chamber section is the second dryer section, the moisture content of the material moisture of this section approaches or reaches critical point, now making full use of microwave has penetrability and can produce a large amount of frictional heat characteristics, can improve rapidly the temperature of material, microwave is the integral body generation effect to material directly, in the inner fuel factor that produces rapidly of material, rate of drying is increased sharply, realize material quick dewatering drying.
Falling-rate periods of drying of the present invention chamber section, material in this section is evaporation substantially, now the flow of hot blast, temperature can suitably reduce a bit, now adopt small power electromagnetic heater falling-rate periods of drying, the convection action of its formation is more remarkable, can greatly improve rate of drying, increase output, reduce drying cost.
Further, microwave and electromagnetic heat source convection current combine, and realize and having complementary advantages, and have possessed the advantage of convective drying and microwave drying, and have overcome shortcoming separately, greatly improve efficiency and the economy of dry run.
