Technical field
The present invention relates to material microwave dryer field, be specifically related to a kind of single-stage belt No leakage microwave dryer.
Background technology
Drying is that most widely used process unit one of operates, and is widely used in the industries such as medicine, chemical industry, food, building materials, papermaking, agricultural chemicals, coating.The mode of most employing convection current, conduction, radiation evaporates the hygroscopic water in material to heating material, make material reach drying purpose.Wherein utilize microwave energy to the technology of heating material drying, last century Mo obtains universal and development in China, because its firing rate is fast, efficient energy-saving, homogeneous heating and be easy to the features such as controls, progressively becomes the drying means that employing is maximum,
Gateway mechanism in existing microwave heating equipment, what generally adopt is the changeless structure of gateway size.Therefore, larger microwave leakage can be caused when can not adapt to much less than the size of gateway of the size of the change of the size of material to be machined, particularly material to be machined.In addition, the gateway mechanism in existing microwave heating equipment mainly by absorb and the microwave of decay leak prevents leakage, therefore can cause the waste of microwave energy.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, provide a kind of single-stage belt No leakage microwave dryer, structure is simple, easily manufactured, can effectively prevent microwave energy from revealing, thus improves drying efficiency.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of single-stage belt No leakage microwave dryer, comprise housing, mass transport belting, feeding device, discharge device and multiple microwave generator, feeding device and discharge device are separately positioned on the two ends of housing, described mass transport belting comprises active roll, driven running roller and the conveyer belt be arranged between active roll and driven running roller, described multiple microwave generator is disposed on above conveyer belt, and the housing above microwave generator also offers hydrofuge passage, the active roll of described mass transport belting is arranged on outside housing, driven running roller is arranged in housing, and at conveyer belt, housing sidewall place is provided with choke groove, described choke groove is rectangular cylinder, a sidewall of its middle cylinder body offers elongated slot, and the length of elongated slot is greater than the width of conveyer belt, described choke groove is fixedly connected with housing by the sidewall adjacent with elongated slot, and elongated slot is arranged on above conveyer belt down.
Described choke groove is close to above conveyer belt and is arranged, and choke groove and conveyer belt be arranged in parallel.
The below of the corresponding choke groove of described conveyer belt is provided with supporting plate, and supporting plate one end is fixedly connected with housing.
Described hydrofuge passage place is provided with dust collect plant.
beneficial effect
1, structure of the present invention is simple, and the active roll of material conveying mechanism and drive unit are arranged on hull outside, overhaul convenient, fast, result of use is good.
2, the present invention is by arranging choke groove at shell nozzle place, make the microwave reflection of leaking possibly being radiated gateway place on material by the reflex of choke groove, or turn back in dryness storehouse, shield completely in drying machine by microwave action region, therefore improve the utilization rate of microwave energy, and then improve microwave energy utilization rate.
