A kind of hermatic door of microwave-heating biomass equipment
Technical field
The utility model relates to microwave energy and uses field, particularly a kind of hermatic door of microwave-heating biomass equipment in the industrialization of the industries such as metallurgy, chemical industry and biomass pyrolytic.
Background technology
Existing microwave-heating biomass equipment all adopt completely open wide, Purely mechanical firmly contact sealing oven door design, though the manufacture of opposite house body, to install with the requirement of quality of fit and maintenance close to harshness, but still cannot reach that microwave is prevented letting out, the safety in production requirement of leakproof.Especially when industrialization continuous seepage, because in-furnace temperature is higher, door body inevitably produces larger thermal deformation, thus cause seal failure, bring microwave leakage, safety of workers operation hidden danger is given prominence to, flue gas and dust leak in a large number, the serious problems such as contaminated environment.
Summary of the invention
The purpose of this utility model is to provide a kind of hermatic door of microwave-heating biomass equipment, it adopts the structure design of non-hard contact and circulating water chennel sealing, not only significantly reduce machine-building and the required precision coordinated is installed, and make full use of absorb microwave optimisation substance---water is to prevent microwave leakage, and effectively reduce the temperature of door body, avoid the seal failure that a body causes because of high temperature thermal deformation, when industrialization continuity is produced, completely avoid microwave, leaking of flue gas and dust, effectively overcome the weak point that prior art exists, its shape, structure or its combination propose a kind of new technical scheme being suitable for practicality.
The utility model is achieved through the following technical solutions: a kind of hermatic door of microwave-heating biomass equipment, comprise a body and doorframe, the outstanding difference of itself and prior art is: door body has outer ring-like deep trouth, the doorframe being positioned at heating using microwave cavity opening part is annular tank, time closed, the outer shroud trough rim of door body, buckles in the annular tank of doorframe uniformly.Be groove structure inside annular tank, the external recirculating cooling water system of the water body in tank.
The structure design of the utility model uniqueness, door body does not have any firmly to contact with microwave equipment cavity, ensure that the dual shield of microwave, the microwave be not completely absorbed in microwave heating chamber, shielded, even if by shield trenches, also absorbed completely by the secondary shield that water ring forms, without any possibility that leaks.The annular tank water body be connected with recirculating cooling water system, can be reduced to 100 ° of below C, substantially stop the thermal deformation of fire door by door temperature; It is inner that flue gas and dust are also completely enclosed within heating using microwave cavity by water ring, completely avoid leaking of microwave, flue gas and dust; Make the hermatic door of such industrial microwave equipment be easy to processing, install, safeguard, maintenance, reliability and safety promote greatly.
Below in conjunction with drawings and Examples, the utility model is set forth.

Detailed description of the invention
Detailed description of the invention is intended to describe in further detail and explain the utility model, instead of limits the utility model by any way.Any simple modifications that those of ordinary skill in the art do the utility model and replacement, all should fall within protection domain of the present utility model.
A kind of hermatic door of microwave-heating biomass equipment, comprise a body 2 and doorframe 1, the outstanding difference of itself and prior art is: door body 2 has outer ring-like deep trouth, the doorframe 1 being positioned at heating using microwave cavity 3 opening part is annular tank, time closed, the outer shroud trough rim of door body 2, buckles in the annular tank of doorframe 1 uniformly.
It is groove structure inside annular tank.
The external recirculating cooling water system of water 4 in annular tank.
In the practice of industrialization continuous seepage, door body 2 and heating using microwave cavity 3 can not produce any firmly to contact.Groove structure inside annular tank 1 coordinates with door body 2 the primary shielding that ensure that microwave.Water 4 is the best materials absorbing microwave, annular tank 1 forms the secondary shield to remaining microwave, and remaining microwave is absorbed completely, flue gas and dust are also sealed in heating using microwave cavity 3 by water ring completely simultaneously, external recirculating cooling water system can be cooled to 100 ° of below C to continuously the groove structure inside door body 2 and annular tank 1, efficiently avoid the above-mentioned seal failure that thermal deformation causes.Guarantee operator not by the impact of the microwave that leaks, realize safety in production and cleaner production.
The utility model is also applicable to microwave metallurgical chemical industry equipment completely.
