Abstract
The utility model relates to a box-type microwave heater, which adopts rotary antenna feed energy. The utility model comprises a box body, a rectangular waveguide coaxial converter (converter for short, similarly hereinafter) which is arranged outside the box body, a rotary antenna which is communicated with the coaxial converter and can rotate around a coaxial rotary end, and a rotary shaft which is fixed on the rotary antenna and is transversely inserted into the converter. After microwave energy enters through a rectangular waveguide, the microwave energy passes through the transition of a ridge waveguide transition segment, the microwave energy is transmitted to the rotary antenna through the converter, a microwave radiates through the antenna, and the microwave carries out microwave heating on a material which is in the box body. A motor drives the antenna to rotate at a certain angular speed through the rotary shaft, when the antenna rotates at 360 DEG, longitudinal and transverse microwave field distribution of the inside of the heater is effectively changed. Compared with other heating forms, the utility model results in more even heating.
Description
Technical field
The utility model relates to a kind of microwave applicator, is specifically related to a kind of tunnel type micro wave heater box or that connected and composed by the heating cabinet more than, particularly the antenna of microwave applicator.
Background technology
Box heater is that application is a kind of very widely in the microwave applicator, and it is not strict with the shape that adds thermal material, is particularly suitable for heating bulk, graininess, granular material.A plurality of chests are tied, can form the tunnel type heater and heat continuously, the monomer chest can be used as batch war proclamation setting forth the purpose of the expedition and enumerating the crimes of the enemy wave heater.Associativity is very flexible, can make up arbitrarily as required.But, people are when using box heater, and how does an important technological problems that runs into promptly make processing materials obtain evenly heating? the method of improving the box heater heating uniformity is a lot, analyze from principle, mainly contain the pattern complementary method, method and near-field illumination method three classes are moved in the field:
1. the pattern complementary method is a kind of the most frequently used method of early stage microwave applicator design, and it is a foundation with the microwave mode resonance opinion of rubbing.According to this theory, microwave energy with multiple different pattern at hollow metal box interior resonance, the field strength distribution of different mode is different, the pattern complementary method is exactly to make the pattern that has two or more in the case simultaneously, utilize the difference of their strength distribution to improve the uniformity of heating, simultaneous mode of resonance number and mode of resonance and their intensity are relevant in the degree of improvement and the case.One Yin Dynasty, simultaneous mode of resonance number is The more the better in the case, the mode of resonance number is many more, the possibility of homogeneous heating property improvement is big more, the heater design of this method to empty van or have very light load be correct reliably, but in high-power commercial Application, because material feedback mouth, the influence of feed inlet and outlet, it is bigger that actual situation and empty van or underloaded situation are departed from, and Here it is improves the basic shortcoming of heating uniformity with the pattern complementary method.
2. the method for moving is exactly to utilize microwave field and the relative position that adds between the thermal material moves the uniformity of improving heating, in the continuous-type microwave heating that conveyer belt is arranged is clamored. it can only improve along the inhomogeneous heating that causes of field intensity branch on the conveyer belt direction inhomogeneous, can not improve the inhomogeneous inhomogeneous heating that causes perpendicular to the direction of transfer field strength distribution.Equally, in the batch heater, in case, install rotating disk, use the motor-driven rotating disk, make the material periodical rotation in microwave field on the rotating disk, it can improve the inhomogeneous inhomogeneous heating that causes of circumferential field strength distribution, but can not improve the inhomogeneous inhomogeneous heating that causes of warp-wise field strength distribution.
3. the near-field illumination method is that top, bottom or side at heating cabinet opened a plurality of feedbacks mouths and improved homogeneous heating.The starting point of this method is not based on pattern theory, and from practice, this method is to improve a more practicable method of heating uniformity.But this method needs a plurality of independently microwave sources to the case energy regenerative, so structure is comparatively complicated.
Summary of the invention
The utility model technical issues that need to address are to disclose a kind of box microwave applicator that adopts the rotable antenna energy regenerative, to overcome the above-mentioned defective that prior art exists.
The technical solution of the utility model:
Microwave applicator of the present utility model comprises:
Heat casing and be in the outer rectangular waveguide-coaxial converter of casing and (be called for short converter, down together.) and be connected with coaxial converter and can be around the rotable antenna in the casing of being arranged on that do to rotate with axle head, the rotating shaft Joint of this antenna and horizontal insertion converter, the rotation of rotating shaft is the rotation of driven rotary antenna, the motor that the other end of rotating shaft is connected by transmission mechanism.
After microwave energy was entered by waveguide, the transition by transition conduit transferred to rotable antenna, and microwave carries out heating using microwave by aerial radiation to the material that is in the casing; Motor drives antenna by rotating shaft and revolves with certain angular speed, when antenna is done 360 ° rotation, can effectively change microwave field vertical and horizontal in the heater and distribute, and compares with the heat form of above-mentioned alternate manner, makes heating more even.
