Description
Technical field
The present invention relates to a kind of microwave heating equipment, especially relate to a kind of microwave heating equipment being applicable to powder body material and volatile material.
Background technology
Microwave heating is a kind of Novel heating mode by material self dielectric loss and self-heating in microwave field, except can making material Fast Heating and heating up, also has and improves reaction speed, improves reacting finisheding degree, reduces the non-thermal effects such as by-products content.
Microwave heating, be produce microwave by the magnetron in microwave generation system, microwave Formation rule in transmission system shakes and transmits, and finally by adpting flange by microwave feed-in reaction cavity, realizes heating material.For reducing the power loss of microwave in transmission system and avoiding causing the electric components job stability in microwave generation system to reduce because of dust adhesion and useful life shortens, often need to arrange blind plate at microwave feed-in mouth.But because the adpting flange near microwave feed-in mouth need adopt water-cooling pattern to ensure equipment good seal to guarantee flange indeformable, therefore to affect temperature by flange water-cooling system lower for blind plate.When microwave equipment is for the treatment of powder material or volatile material, dust easily condensation on blind plate, gathers and formed and block.And due to the microwave power of microwave feed-in mouth comparatively concentrated, the material blocked on blind plate is rapidly heated and even forms focus, thus causes blind plate scaling loss and puncturing, and then jeopardizes the operation stability of microwave device useful life and integral device.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly prevents blind plate scaling loss, puncture thus improve the microwave heating equipment being applicable to powder/volatile material of the operation stability of microwave device useful life and integral device.
In order to solve the problems of the technologies described above, the microwave heating equipment being applicable to powder/volatile material provided by the invention, comprise body of heater, burner hearth, microwave generation system, microwave feed-in mouth, external thermal insulation or inner thermal insulating layer, be provided with in described burner hearth and be in the described microwave body of heater of feedback described in entrance side and the wave transparent dividing plate between the material in described burner hearth.
In described burner hearth, be provided with gas flow purging device, the outlet of described gas flow purging device aligns described wave transparent separator face to the side of material.
Described wave transparent dividing plate is located between described inner thermal insulating layer and material, and namely described inner thermal insulating layer is located between described body of heater and described wave transparent dividing plate.
Described wave transparent dividing plate is located between described body of heater and described inner thermal insulating layer.
Described wave transparent dividing plate is ceramic wafer, microcrystal glass plate, micarex, quartz plate, polytetrafluoroethylene composite plate, polyether-ether-ketone composite plate, polytetrafluoroethylmodified modified plastic plate or polyether-ether-ketone modified plastics plate.
Adopt the microwave heating equipment being applicable to powder/volatile material of technique scheme, be for the blind plate scaling loss easily occurred in microwave equipment process granular material and volatile material process, puncture, cause the problems such as microwave equipment fluctuation of service, operational efficiency are low and propose a kind of microwave heating equipment being applicable to above-mentioned material process.Wherein, wave transparent dividing plate plays buffer action to from the airborne dust of material and volatile matter; The air-supply of gas flow purging device purges wave transparent dividing plate, prevents dust in the condensation of wave transparent dividing plate or gathers.
The present invention has following beneficial effect:
Prevent material from gathering at blind plate, avoid heating process to inhale microwave heating fast because of accumulation dust and cause blind plate scaling loss or puncture;
Simultaneously because dividing plate does not connect water cooling plant, and closer to thermal source, therefore the plate surface temperature of dividing plate is higher compared with the plate surface temperature of blind plate, can effectively reduce volatile matter condensation on plate face;
Adopt air-flow to purge wave transparent dividing plate, prevent dust from gathering;
Improve thermal field and atmosphere evenness: wave transparent dividing plate the natural subsidence stroke that effectively can shorten dust is set, therefore equipment does not need the natural subsidence stroke being improved dust by increasing device height, decreases heat loss simultaneously; The flowing that purging system is preventing dust stop from adding atmosphere and heat in body of heater simultaneously, thus improve the uniformity of thermal field and atmosphere.
In sum, the present invention a kind ofly prevents blind plate scaling loss, punctures thus improves the microwave heating equipment being applicable to powder/volatile material of the operation stability of microwave device useful life and integral device.
