Abstract
The utility model relates to a magnetron top-mounted microwave dryer. A material conveyer belt is arranged inside the drying chamber of the dryer, and along the conveyer belt on the top of the dryer is equipped with at least one magnetron upon which is arranged a heat elimination fan. Outside at least one set of magnetron and the heat elimination fan is arranged a hot air collecting chamber whose hot-air outlet is connected with a set of air-drawing device, the outlet of which connected with the drying chamber of the microwave dryer. Without increasing energy consumption, the utility model makes full use of the waste heat produced during normal operation of the magnetron, improves the capacity of moisture absorption by increasing the ventilation temperature, and increases the utilization ratio by about 20% and the drying uniformity inside the material layer.
Description
Technical field
The utility model relates to a kind of magnetron overhead type microwave dryer.
Background technology
The not special ventilating mechanisms that utilizes the magnetron waste heat that is provided with in the existing micro-wave drying device, the moisture exhausting that is unfavorable for afterheat utilization and material, the heat that magnetron heat radiation is wherein sent all emits (particularly concentrating dynamical type heating using microwave, drying machine) in vain, thereby causes very big waste (be approximately total power consumption 20%).
The utility model content
At the problems referred to above, task of the present utility model provides a kind of magnetron overhead type microwave dryer, improves the drying efficiency of material, simultaneously the heat radiation heat of magnetron fully is used.
For achieving the above object, the technical solution of the utility model is: a kind of magnetron overhead type microwave dryer, in the drying machine drying chamber, be provided with material conveyer belt, along the material conveyer belt direction at least one magnetron is installed at the drying machine top, be equipped with cooling fan on the magnetron, outside the cooling fan of at least one group of magnetron and magnetron, be provided with the hot blast collecting chamber, be connected with a cover blower unit on the hot-blast outlet of hot blast collecting chamber, the air outlet of blower unit is communicated with the drying chamber of microwave dryer.
In the drying machine drying chamber conveyer belt above button be provided with downward opening blowing cover, the blowing mouth at blowing cover top is connected with the air outlet of blower unit by guide duct in the machine.
Described blowing cover is a trough type cover body along the belt direction setting, and the guide duct of this trough type cover body and connection thereof is made by low microwave consumable material.
The following induced duct that connects on the last induced duct that connects on the air inlet of described blower unit by air exhauster, air exhauster, the air outlet of air exhauster is formed, the import of last induced duct is connected with the hot-blast outlet of hot blast collecting chamber, the outlet of following induced duct is fixed on the machine wall of drying machine by ring flange, corresponding machine wall place is provided with air vent, and the import of the guide duct in the drying machine also is fixed on this air vent by ring flange.
Be equipped with the micro-wave screening filter on the described air vent.
The air output of described blower unit is at every square metre of drying area air quantity 0.1m each second
3In, make material bed interior wind speed less than 0.1m/s.
As seen, after this magnetron overhead type microwave dryer is provided with blower unit, for good condition has been created in the hydrofuge ventilation of microwave dryer, and enlarged range of application, can adopt the mesh-like conveyer belt except being suitable for all, the continous way of dry shot shape and puffy material or intermittent type microwave drying machine also are suitable for being merely able to adopt cord shape conveyer belt, the application of the continous way of dry powdery material or intermittent type microwave drying machine etc. outside using.Because the wind regime of blower unit is taken from the heat radiation hot blast of magnetron, so under the prerequisite that does not additionally increase energy consumption, make full use of the waste heat that produces under the magnetron normal operating conditions, by improving the temperature of draft, improved the ability of moisture absorption, and it is about 20% that capacity usage ratio is improved, and improved the uniform drying in material bed; Because the draft direction from top to bottom, the flow direction in material bed is consistent with the direction of microwave radiation material, is following current and ventilates, so help improving material bed interior uniform drying and drying efficiency.
