Abstract
The utility model relates to a waveguide used for vacuum microwave drying equipment, which can effectively solve the problems that a vacuum chamber is caused, vacuum drop is caused or the needed vacuum cannot be reached due to the bad tightness of the existing microwave waveguide. The utility model adopts a technical scheme as follows: the waveguide used for the vacuum microwave drying equipment comprises a vacuum chamber, and a fixed opening is configured on the vacuum chamber; a base is fixed on the fixed opening by welding, and an opening is configured on the base; the opening is provided with a teflon sealing block; a sealing gasket is arranged between the teflon sealing block and the base; a pressing plate is arranged at the upper part of the base; the pressing plate is provided with a microwave inlet corresponding to the teflon sealing block. The waveguide used for the vacuum microwave drying equipment provided by the utility model has the advantages of novel and unique structure, safe and convenient use, good tightness and capability of effectively reducing the attenuation of the microwave in the waveguide.
Description
Technical field
The utility model relates to microwave device, particularly a kind of vacuum microwave drying device waveguide.
Background technology
Present microwave dryer waveguide assembly, due to structural reason, poor sealing, in use, its vacuum chamber is known from experience gas leakage, causes vacuum to decline, or does not reach required vacuum, therefore, thus improve the structure of waveguide or mounting means to improve its sealing effectiveness be the key of dealing with problems.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of vacuum microwave drying device waveguide, can effectively solve existing microwave waveguide poor sealing and cause vacuum cavity, cause vacuum to decline, or do not reach the problem of required vacuum.
The technical scheme of its solution is, comprise vacuum cavity, on vacuum cavity, there is fixing port, on fixing port, be welded with base, on base, there is opening, teflon seal piece is housed on opening, between teflon seal piece and base, sealing gasket is housed, pressing plate is equipped with on base top, has the microwave import corresponding with teflon seal piece on pressing plate.
The utility model novel structure uniqueness, safe and convenient to use, good airproof performance, can effectively reduce the decay of microwave in waveguide.
Accompanying drawing explanation
Fig. 1 is front view sectional structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further details.
Provided by Fig. 1, the utility model comprises vacuum cavity, on vacuum cavity 1, there is fixing port, on fixing port, be welded with base 2, on base 2, there is opening, teflon seal piece 3 is housed on opening, between teflon seal piece 3 and base 2, sealing gasket 4 is housed, pressing plate 5 is equipped with on base 1 top, has the microwave import 6 corresponding with teflon seal piece 3 on pressing plate 5.
The utility model is fixed on excitation cavity 7 on pressing plate 5 through screw, first vacuum cavity 1 is cut out to the fixing port measure-alike with base 2, and then base is welded on vacuum cavity, pressing plate 5 compresses teflon seal piece 3 and sealing gasket 4, assurance vacuum cavity can not be revealed, what select due to sealing block is not absorb microwave but polytetrafluoroethylene (PTFE) that microwave energy penetrates completely, can guarantee that microwave energy can not lose.
The waveguiding structure of the technical program is simple, easy to use, can effectively suppress microwave leakage and reach sealing effectiveness, and effectively reducing the decay of microwave in waveguide the inside.
