Description
Technical field
The utility model relates to a kind of baking oven, is specifically related to a kind of high accuracy vacuum drying oven.
Background technology
Vacuum drying oven, is again vacuum oven, vacuum bakeout case, Zhen Kong oven, is widely used in the industries such as chemical industry, electronics, food, light industry, medicine, can carries out drying under vacuum conditions to material.Have rate of drying fast, pollute little, not to the advantage that the inherent quality of dried article damages.
Vacuum drying oven carries out dry a kind of box-type drying equipment under dried material being in condition of negative pressure.It utilizes vavuum pump to carry out bleeding dehumidifier, makes to form vacuum state in operating room, reduces the boiling point of water, accelerate dry speed.Vacuum drying oven can obtain higher rate of drying at a lower temperature, and Btu utilization is abundant, is mainly applicable to heat sensitive material and contains solvent and need the drying of recycling design material.Before it is dried can disinfection, in dry run, any impurity is without being mixed into, and this drier belongs to static vacuum drier, therefore the formation of dried material can not damage.Mode of heating has: steam, hot water, conduction oil, electric heating.Vacuum drying oven aims at dry heat sensitivity, easily decomposition and readily oxidizable substance and designs, and internally can be filled with inert gas, particularly the article of some complicated components also can carry out rapid draing.Vacuum drying carries out drying under dried material being in vacuum condition.It utilizes vavuum pump to carry out bleeding dehumidifier, makes to form vacuum state in operating room, reduces the boiling point of water, accelerate dry speed.Vacuum drying oven by condition of high vacuum degree vavuum pump, casing, operating room, electric heater and digital temperature device composition, can setting vacuum degree condition under steady operation, cabinet shell is with cold rolled plate plastic-blasting, attractive in appearance pleasing.Interior case, with the withstand voltage PROCESS FOR TREATMENT of the close weldering of corrosion resistant plate, is mixed the silica gel sealing pressure pad on door, the air-tightness in guard box, and is adopted spun-glass insulation, provide thermal insulation, saves energy consumption effect.Heating board is arranged on internal box four side, to ensure temperature homogeneity.
Vacuum drying oven and glove box support the use, mainly Electric heating, can be undertaken heating by button, vacuumize, inflated with nitrogen, heating calendar scheduling function, traditional vacuum baking oven is all adopt heating plate to heat, there are two kinds of mode of heatings: a kind of mode of heating being heating plate and being attached to the outside of casing, by box body wall, heat is imported into vacuum chamber, heat can not be delivered in casing in time, although it is enough large that heating plate size is done, all can not stick box body wall, heat uneven, and bad installation, inconvenient maintenance; Another kind of mode be heater strip around cabinet wall, outside presses heating plate, although heat transfer rate is fast, but adopt be 220V voltage heating, heater strip often ruptures, and the electrode wires of heater strip also will from box body wall perforate draw, be not easy sealing, cause box body tightness bad.
The shortcoming of the structural principle of traditional vacuum baking oven is:
One, heating plate is directly attached on cabinet exterior, although size do very large, all can not encase cabinet exterior, heat uneven.
Two, heat transfer cooling effectiveness is slow.First heat tank wall during heating and then just heat is delivered to box house, heat transfer is slow, and will wait until during cooling that the cooling of whole casing is completely just passable, cooling velocity is slow, will add water cooling plant if desired.
Three, heat insulation and preservation effect is bad.4 pieces of heating plate externally heating plate dividing plates make of 0.8mm corrosion resistant plate, and play heat-blocking action, although one layer of heat preservation cotton has been wrapped up in outside, effect of heat insulation is not fine, is heated to uniform temperature and heat-preservation cotton wrapper sheet temperature will be made to increase rapidly, easily scald arm.
Four, inconvenient maintenance.If heating plate or other damage parts, shell, various meter, heat-preservation cotton etc. all disassemble just can be changed, and wastes time and energy.
