Description

A kind of use for laboratory Multifunctional oven

Technical field

The utility model belongs to baking oven technical field, and in particular to a kind of use for laboratory Multifunctional 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.

Existing general baking oven weighs initial weight for needing electronic scale of arranging in pairs or groups when testing volatile matter outside baking oven Afterwards, it places into baking oven, carries out drying a period of time, measure its weight again after its cooling after pull-out.Some samples are especially Be when taking out cooling after the heating, is easy by the moisture absorption, causes test result inaccurate for powder material, and cool down needs compared with For a long time, the fugitive constituent if necessary to test different time is then more troublesome, also cannot achieve the purpose of long term monitoring.

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.

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 sample.

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 It is provided with distribution of air flow baffle, if offering a air hole on the distribution of air flow baffle, the intracorporal middle part of case is equipped with Temperature sensors of high precision, the temperature sensors of high precision are electrically connected with control cabinet.Not only temperature controls above-mentioned preheating oven Precision is high；And thermal field is uniform in baking oven, ensure that the pre-heat effect to polypropylene board.The bottom of cabinet described in the patent Being equipped with leveling support leg can be used for the leveling of baking oven entirety, but the levelness of step shelf may be different, for being cast The thickness that not can guarantee film when injection molding is uniform.

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.

Chinese patent CN206131624U discloses a kind of anti-floating dust convection oven, including cabinet, body side setting drum Blower, tank floor are arranged heating element, the chamber door of observation panel are provided with before cabinet, it is characterised in that: set through cabinet Support rod is set, arranges several sample discs along support rod length direction sequence through support rod, being partly wrapped in the setting of sample disc side can The baffle of air blower is blocked, the baffle plate setting is between sample disc and air blower.The purpose of the utility model is to solve to make When drying powder sample with convection oven, powder sample caused by air-flow is unstable at blast orifice drifts.To achieve the above object, One baffle is set between blast orifice and sample disc, a kind of anti-floating dust convection oven for making sample powder avoid air port is provided. But baffle is located at and has only covered the blast orifice of side in the design, the air-flow of top and side is still easy to blow in dust It walks.And the baking oven cannot be used to be cast injection molding simultaneously, be not suitable for use in the volatile matter of test sample.
