Abstract
The invention discloses a process technology for guaranteeing continuous production of industrial microwave facilities. In the invention, microwave is adopted to penetrate into the interior of a material so that the exterior and the interior of the material generate heat energy at the same time, the phenomenon of dry exterior and wet interior doest not exist, and the water ratio of the material is controlled by controlling the radiation time of the material by the microwave; double-sided cooling is carried out on a multiple tube microwave generating source, thus improving the service life of the microwave generating source; and at the same time, a distributing device and a dustproof airtight device are respectively arranged on a feeding funnel and a hopper, thus preventing the leakage and dust raising of the material during the transporting process, improving the material transporting efficiency, and reducing environmental pollution and harm to the health of workers.
Description
Technical field
The present invention relates to the powder body material drying equipment, relate to a kind of technology that ensures that the industrial microwave apparatus continous way is produced especially.
Background technology
Microwave be frequency at the electric wave of 300 megahertzes to 300 gigahertzs, the hydrone in the heated medium material is a polar molecule.It is under the effect of fast-changing high frequency points magnetic field, and its polarity orientation will change along with the variation of external electric field.Cause the mutual friction effect of motion of molecule, this moment, the field energy of microwave field was converted into heat energy in the medium, and temperature of charge is raise, and produced thermalization and a series of processes such as expanded and reached the purpose of micro-wave drying.
Microwave energy is penetrated into material inside, makes and produces heat energy in the material table simultaneously, can not produce wet phenomenon in outer the doing.Along with the material surface moisture constantly evaporates, material surface temperature will be a little less than the nexine temperature, and the thermograde of formation is by outside the interior sensing, and is consistent with the migratory direction and the heat migratory direction of the vapour pressure of following generation in the heating process.According to the dry materials theory, this heated condition dry materials that is highly advantageous to.Modern industry production is mainly used in sintering, the heating of meticulous goods such as mineral smelting, powder metallurgy, function ceramics, carbon material, dry, the processing and fabricating of various powder body materials, and the quick extraction of active ingredient, the fast deep drying of pottery, cardboard, timber, food, medicine, chemical industry etc.But traditional microwave powder body material drying equipment is the fault rate height in process of production, is difficult to accomplish the production of 24H continous way; Loading and unloading are difficult to accomplish the automation setting, make material be subjected to microwave irradiation inhomogeneous in dry run, cause dry materials inhomogeneous; Dust raising phenomenon in the blanking process is difficult to solve, and when reducing productivity ratio workman's health is also had certain harm, and environmental pollution is also bigger.
Summary of the invention
The object of the invention is exactly to be to overcome above-mentioned deficiency of the prior art and a kind of production continuously, high efficiency, a kind of technology that ensures that the industrial microwave apparatus continous way is produced simple to operate be provided.
For achieving the above object, the present invention realizes by the following technical solutions:
1, material is placed into elevating hopper, is tiled in equably on the transport tape behind the distribution device of elevating hopper bottom, and wherein width is 600mm～1200mm, and thickness is 20mm～80mm;
2, transport tape by certain speed uniform motion, is written into the microwave drying cavity to material under the drive of motor;
3, material is subjected to the irradiation of microwave in cavity, produces steam, and steam moves upward, and enters the hydrofuge pipeline from both sides, cavity top, is discharged to outdoor under the dehumidifier effect of blower fan through external pipe;
4, blower fan is blown into the cold air after air cleaner filters in the air channel, cooled off the one side of microwave source in the air channel, blow to the space between the saturating ripple thermal insulation board in microwave source and below simultaneously, another side to microwave source cools off, the hot blast of discharging in the blower fan utilizes pipeline to be blown in the microwave action chamber by hot air circulation, as another thermal source to material processing;
5, after drying was finished, material arrived discharging opening, enters the storehouse that connects material by hopper.
Advantage of the present invention:
1), in the technical program multitube microwave source is carried out two-sided cooling technology.Multitube microwave source system and cooling system are contained in the top in microwave action chamber, wherein 1～9 of every square metre of layout microwave source, and covering the heat insulation special material plate of the saturating ripple of one deck below the waveguide of microwave source and between the microwave cavity inside top, this sheet material does not absorb microwave, microwave is seen through fully and good effect of heat insulation is arranged.Cold air after air cleaner filters is blown in the air channel, cooled off the one side of microwave source in the air channel, blow to the space between the saturating ripple thermal insulation board in microwave source and below simultaneously, the another side of microwave source is cooled off, improved the service life of microwave source; The hot blast that cooling system is discharged utilizes pipeline to be blown in the microwave action chamber by hot air circulation, as another thermal source to material processing, has saved the energy when improving drying efficiency; Can select as required to be controlled the moisture content of material by the time of microwave irradiation.
2), TVS is installed, make microwave leakage value≤1mw/cm at two ends, microwave action chamber
2, be higher than national standard≤5mw/cm
2, can effectively prevent microwave leakage, increase work efficiency, reduce production costs.
3), the distributing device of elevating hopper is evenly distributed on the conveyer belt material, makes material dry uniformly; The sealed dust-tight device of hopper can not produce material and leaks and airborne dust in the process of transporting, improve the efficient of mass transport, reduces environmental pollution and to the harm of workman's health.
4), control cabinet for power distribution and power-supply system are contained in a side in microwave action chamber in the technical scheme, even equipment also can carry out maintenance and repair under the state of normal boot-strap, have guaranteed the production running of equipment continous way.
The specific embodiment:
1, material is placed into elevating hopper, is tiled in equably on the transport tape behind the distribution device of elevating hopper bottom, and wherein width is 600mm～1200mm, and thickness is 20mm～80mm;
2, transport tape by certain speed uniform motion, is written into the microwave drying cavity to material under the drive of motor, selects material on average to shine the volume time according to the characteristic and the dehydration rate of material, generally in 30min;
3, material is subjected to the irradiation of microwave in cavity, produces steam, and steam moves upward, and enters the hydrofuge pipeline from both sides, cavity top, is discharged to outdoor under the dehumidifier effect of blower fan through external pipe;
4, blower fan is blown into the cold air after air cleaner filters in the air channel, cooled off the one side of microwave source in the air channel, blow to the space between the saturating ripple thermal insulation board in microwave source and below simultaneously, another side to microwave source cools off, the hot blast of discharging in the blower fan utilizes pipeline to be blown in the microwave action chamber by hot air circulation, as another thermal source to material processing;
