Specific embodiment

The technical solution of the utility model is illustrated below by way of specific embodiment and in conjunction with attached drawing.

Embodiment 1

It is specific as follows if Fig. 1 and 2 is that one kind realizes the equally distributed structure of microwave in microwave equipment: including cabinet 1, 1 internal shaping of cabinet has drying cavity 2；Leaky antenna cavity 3 is installed, leaky antenna cavity 3 is communicated with microwave source at the top of cabinet 1 4；Leaky antenna cavity 3 is uniformly formed with several routed waves of the leaky antennas being connected to drying cavity 2 with the contact surface of drying cavity 2 Mouth 5；The rotation at 1 top of cabinet is connected with rotary blade 6, and blade 61 is equipped on rotary blade 6.The surface of further blade For curved and it is formed with several irregular protrusions.

The routed wave mouth 5 of several leaky antennas in this way by leaky antenna cavity 3 and corresponding to leaky antenna cavity 3 makes one A microwave source can be burst by leaky antenna wave mouth 5 drying cavity 2 in be separated into multiple uniform microwave sources, microwave is uniform It is transmitted in drying cavity 2, so that microwave can be uniformly distributed in drying cavity 2.

But although practical discovery, above structure make distribution of the microwave in drying cavity 2 uniform than before, but in The microwave intensity in portion is still apparently higher than surrounding, and the microwave intensity burst immediately below at wave mouth 5 of each leaky antenna also above its four The intensity in week.Therefore more uniform in order to spread microwave, rotary blade 6 is set, it is micro- to middle part by the rotation of rotary blade 6 Wave carries out randomness diffusing reflection, so that the microwave drying entirely in drying cavity 2 is more uniform.And it further improves Are as follows: the blade 61 is helical form, and so it can realize and entirely be dried to microwave by microwave refractometer to from all directions The three-dimensional comprehensive diffusing reflection of cavity 2, so that the microwave intensity in drying cavity 2 everywhere is in highly uniform state.Leaf Gap 11 is formed between piece 61.

As shown in figure 3, leaky antenna cavity 3 and leaky antenna are burst, wave mouth 5 can also use several single 4 generations of microwave source It replaces.But its microwave source 4 needed is more, energy consumption is high, waste of resource.

Embodiment 2

On the basis of embodiment 1, in order to carry out more uniform drying to water paint, as shown in Figures 4 and 5, in cabinet 1 Side is formed with external wind entrance 8, and the exit of the external wind entrance 8 is equipped with external wind air diffuser 9.External wind entrance 8 Periphery monomer microwave crevasse 10 is installed, cooperation monomer microwave crevasse 10 is equipped with single microwave source, to be formed a kind of aqueous Paint drying equipment.In this way on the basis of above-mentioned microwave drying is uniform, when so that the wind of external wind entrance 8 entering, pass through monomer Microwave crevasse 10 is heated, and the surface that external wind air diffuser 9 makes external wind uniformly blow over water paint is then passed through, thus Realize the uniform flash baking to paint film.

Embodiment 3

As shown in Examples 1 and 22, in industrial microwave drying equipment field, entrance can be facilitated to set in order to meet bulk material Standby interior, equipment opening can be made very big, open end can using door come provision for sealing, but due to microwave particularity, Need to ensure that the cavity junction of door and equipment not reveal the microwave beyond standard, it will usually be disposed between door and cavity Perhaps soft metal silk carrys out shield microwaves but metal mesh item or metal strand because being often subject to squeeze or rub to metal mesh It wipes and there is loss, certain on-off times there is the probability of failure, it is therefore desirable to which method in addition solves microwave from leakage Problem.The specific method is as follows:

As shown in Figures 6 and 7, cooperation cabinet 1 is equipped with metallic door 12, and forming is fluted at the cabinet 1 of 12 periphery of metallic door 13, it is equipped at groove 13 and inhibits piece 14.In embodiments herein, drying cavity 2 can be named as microwave cavity.

Inhibiting piece 14 is two or more.Inhibit the controlled size of piece 14 within the scope of 25mm-38mm, microwave power For 2450MHz, it is made to generate half-wavelength synergistic effect, forms reactance system.The microwave penetrated in this way from 12 gap of metallic door, A part can be suppressed the reflection of piece 14, to cancel out each other with the microwave interference that is not reflected, thus greatly reduce microwave Amount of leakage.When inhibiting piece is two or more, the adjacent spacing inhibited between piece 14 is less than 30mm.

Inhibit 14 bottom of piece to extend and be formed with fixinig plate 15, forms U-shaped or zigzag configuration；Fixinig plate 15 passes through staking, welding Or screw is fixed on 13 bottom surface of groove.

Inhibit piece 14 most basic for vertical baffle structure, but as shown in FIG. 7 and 8, inhibit 14 bottom of piece to extend forming There is fixinig plate 15 to form fall down U-shaped or zigzag configuration or L-shaped structure；Fixinig plate 15 is fixed on groove by staking, welding or screw 13 bottom surfaces.It may be that n shape structure is fixed by welding.

It above are only one of the utility model specific guiding embodiment, but the design concept of the utility model not office It is limited to this, all non-essential modifications to the present invention made by this concept should belong to the guarantor for invading the utility model Protect the behavior of range.
