Description
Technical field
The invention belongs to baking oven technical fields, and in particular to a kind of multifunctional electro-heating circulation convection oven.
Background technique
Convection oven is common equipment in laboratory and production, can make oven temperature more evenly by air blast, reach
It to the effect that is rapidly heated, can be used for the drying of solid powder, can be used for liquid resin curtain coating casting, can also use
In the Determination of Volatile Matter of various samples.
Injection molding, such as fuel battery proton exchange film or liquid epoxies and liquid silicon are cast for liquid resin
Rubber in baking oven film-forming process using needing for the mold that liquid charging stock is perfused to be put into baking oven, and then baking and curing forms, and makes
Final film thickness is more uniform, needs to level baking oven into the performance test for avoiding causing because non-uniform film thickness is even influencing material before drying
As a result inaccurate.Levelling device is arranged at all few levelling devices of common baking oven, some baking oven bottoms, but due to baking oven multilayer
It is not to be substantially parallel between placement plate, leads to that multilayer placement plate cannot be leveled simultaneously, and use the levelling device of baking oven bottom
Operation is also inconvenient.
In order to reduce the volatile matter of the sheet material after solidifying, it usually needs it is put into baking oven and carries out two sections of solidifications, and it is existing
Baking oven can only lie in sheet material on partition, and area occupied is larger, cannot be stacked between each sheet material or fill it is folded, for irregular
Sample, many areas can be wasted by being placed on partition, it will usually multilayer insulating panel is set, with improve its sheet material batch processed amount and
Treatment effeciency, but not only increase cost in this way, also can distance setting be too small between partition is also inconvenient to pick and place sample.And every
The setting of plate is excessively also unfavorable for the circulation of hot-air, and sheet material, which is attached on one side on partition, to be also unfavorable for sheet material and sufficiently connect with hot-air
Touching, is unfavorable for volatile matter and evaporates, substantially reduce the volatile matter removal efficiency of sheet material.
For the solid sheet material of softwood matter performance test when, in order to make its heating more evenly, should be avoided and be directly placed at
In heating plate or in netted placement plate, because will lead to its upper and lower surface uneven heating in this way, its performance is influenced, it is tested and waves
Hair timesharing in order to make wherein volatile matter faster volatilize, it is also desirable to come into full contact with it with air.Existing baking oven is all not provided with
It can fix and be evenly heated solid sheet material and test the device of its volatile matter.
Existing baking oven cannot generally be adjusted wind speed, can not adjust wind speed according to service condition, cannot be used to be cast simultaneously
The volatile matter of injection molding and test gas-solid.
In addition existing general baking oven weighs just starting weight for needing electronic scale of arranging in pairs or groups when testing volatile matter outside baking oven
It after amount, places into baking oven, carries out drying a period of time, measure its weight again after its cooling after pull-out.Some samples are outstanding
It is when taking out cooling after the heating, to be easy the moisture absorption for powder material, causes test result inaccurate, and the needs that cool down
Long period, the fugitive constituent if necessary to test different time is then more troublesome, also cannot achieve the purpose of long term monitoring.
Chinese patent CN203957203U discloses a kind of preheating oven comprising cabinet is provided with case on the cabinet
Door, which is characterized in that having heaters and an at least thermal field circulating fan is arranged in the intracorporal bottom of case, and in the cabinet
Several layers are provided with for placing the shelf for being preheated product, the two sides of the shelf in the top parallel interval of the heater

The loss of amount, start by set date switch and timing are turned off the switch for being timed the setting that starting and timing are closed to baking oven.But
It is the patent for being still inconvenient to level when casting film, the thickness that not can guarantee film is uniform, and not side when film secondary curing
Just it fixes, can not also test its volatile matter simultaneously.
Chinese patent CN201320778830.8 discloses a kind of electric drying oven with forced convection, be provided on cabinet inner cavity and
Door, inner cavity are provided with the blast orifice for lateral outlet air, vertical hurricane globe are covered on blast orifice.It is effectively right using the design
The hot wind that blast orifice is formed is separated or deflecting, so that the aluminium-foil paper for carrying sample is stablized in the lumen, is not easy to tumble.It should
Porous hurricane globe is arranged before blast orifice to reduce wind speed in design, and aluminium-foil paper sample disc is prevented to be turned over.But this sets
Meter also suffers from certain drawbacks.If drying powder sample in air dry oven, powder sample is light, is easy to be dispelled, only
It is only that the effect that powder sample radix saposhnikoviae is not achieved in porous hurricane globe is set in blast orifice.And the baking oven cannot be used to be cast simultaneously
Injection molding is not suitable for use in the volatile matter of test sample.
