Description
Technical field:
The present invention relates to a kind of process equipment, specifically refer to a kind of for the energy-conservation far-infrared thermal baking box in Baking out technical field.
Background technology:
Traditional Roasting oven structure mainly has two kinds, and the structure of the first is by the internally installed all kinds of electrothermal tubes at toaster body, and its electrothermal tube is rustless steel electrothermal tube or pottery infrared electric heating tube or quartz electrothermal tube, directly baking box inside is heated after energising；The structure of the second is by the internally installed all kinds of fuel oil equipments of toaster body or gas-fired equipment, directly baking box being internally heated by oil or natural gas.
But no matter being the baking box adopting above-mentioned any structure, toaster body is required for installing air channel shrouding and circulated air, by circulation canal, the toasted thing body within toaster body is heated during work.Traditional heating technique is to heat from outside to inside, temperature reaches a timing inside just can be sent to inside, heat is in the process of transmission, high near the temperature of interior oven walls, and the temperature in centre position is low, cause the internal heating of toaster body uneven, the heat that toasted thing body absorbs easily runs off, and causes that the utilization rate of toasted thing body absorption heat is low, and degree of drying is failed to act and thought in the same way, time required for baking is excessively permanent, and energy loss is too high.
Summary of the invention:
For the deficiency existing for above-mentioned background technology, the present invention provides that one can make the internal homogeneous heating of working box, programming rate is fast, reaches cured effect and the significant far-infrared thermal baking box of energy-saving effect.
In order to realize above-mentioned technical problem, the energy-conservation far-infrared thermal baking box of one provided by the present invention, its structure includes the casing being provided with conveyer belt.Described casing has several carbon fiber far-infrared heat-generating pipes internally installed, described carbon fiber far-infrared heat-generating pipe is arranged on around conveyer belt, casing offers exhaust outlet at top, and casing is provided with, on outer side edges edge, the control box being connected with carbon fiber far-infrared heat-generating pipe.
Preferably, described casing is rectangle Open architecture or rectangular sealed structure, meets the needs of different roasting mode.
Further, described conveyer belt is spreaded type conveyer belt or suspension type conveyer belt.
Specifically, described carbon fiber far-infrared heat-generating pipe phosphorus content is at least the carbon fiber of 99.7%, processes with 1500 DEG C of 2500 DEG C of high temperature cabonizations again and form after 350 DEG C 450 DEG C decomposition are extruded.Carbon fiber far-infrared heat-generating pipe has the advantages that penetration power is strong, and thermal inertia is little, it is not necessary to air channel shrouding and circulated air, it is adaptable to all kinds of roasts.
It addition, for better effect of optimization, it is also possible to the sandwiched aluminium silicate wool for improving heat insulation effect of interior at casing.
What the present invention innovated arranges far infrared heating pipe in casing, utilizes the mode of radiation to be directly heated toasted thing body heating up so that it is to have highly efficient and energy-conservation effect.Far infrared is as a kind of electromagnetic wave that human body is useful, and its wavelength is between 6.0～l000 μm.When it is radiated object by radial pattern, the Radiation transport absorbed by object, to particles such as the atom in object, molecules, makes these particle generation irregular movements, causes the thermogenic action of object, be called an effect of far infrared, also referred to as warming effect.Owing to the ultrared wavelength of the wavelength ratio of far infrared is longer, therefore heats is better.
Toasted thing body is directly heated by the present invention, does not need air to make medium, and heat transfer is fast, and heat energy is directly diffused into toasted thing, is not absorbed by intermediate material, reaches energy-conservation purpose；Again because it belongs to overall heating, the place that far-infrared radiation is arrived, intensification uniformity is good, not by with or without air impact, namely reaching homogeneous temperature, without heating blind area, without the temperature difference.The present invention is compared to traditional baking box, energy consumption saving at least 40%, and required technique baking time promotes at least 50%, and effect is notable, and cleanliness factor is high, will not play dirt.
Simple in construction, easy to maintenance.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is described in further detail.

Fig. 2 is the structural side view of the embodiment of the present invention two.
In figure, 1, casing, 2, conveyer belt, 3, carbon fiber far-infrared heat-generating pipe, 4, exhaust outlet, 5, control box.
Detailed description of the invention:
The structure of the present invention is made up of casing 1, and casing 1 is provided with conveyer belt 2.Described casing 1 has several carbon fiber far-infrared heat-generating pipes 3 internally installed, described carbon fiber far-infrared heat-generating pipe 3 is arranged on conveyer belt 2 around, casing 1 offers exhaust outlet 4 at top, and casing 1 is provided with, on outer side edges edge, the control box 5 being connected with carbon fiber far-infrared heat-generating pipe 3.
Described casing 1 is rectangle Open architecture or rectangular sealed structure.
Described conveyer belt 2 is spreaded type conveyer belt or suspension type conveyer belt.
Described carbon fiber far-infrared heat-generating pipe 3 phosphorus content is at least the carbon fiber of 99.7%, processes with 1500 DEG C of 2500 DEG C of high temperature cabonizations again and form after 350 DEG C 450 DEG C decomposition are extruded.Carbon fiber far-infrared heat-generating pipe 3 penetrance is strong, is absent from heating blind area；Radiant intensity is high, is four times of common exothermic material；Further, owing to the electric conversion efficiency of carbon fiber is up to more than 92%, heat effect, compared to strong at least three times of tradition exothermic material, can save the energy 40% under comparable operating conditions.
In dry run, owing to the body surface moisture being dried or solvent constantly absorb heat evaporation so that the temperature of body surface reduces, and the temperature causing interior of articles is higher than the temperature of body surface, and temperature spreads from inside to outside.Additionally, will also result in the movement of the interior of articles gradation of moisture, moisture is always moved from the place that water content is more toward the local of moisture content less, in other words: it is consistent that the moisture diffusion of interior of articles spreads both directions with heat, thus accelerating the process that object dries.
Wavelength is approximated owing to radiation penetrates the degree of depth (depth of penetration heating) of object, and far infrared is more longer than near infrared waviness, particularly the molecule natural frequency of the material such as the tranmitting frequency of far infrared and plastics, macromolecule, water matches, it is easy to cause the molecule fierceness of these materials to resonate.So, far infrared can be penetrated into inside material, it is easy to is absorbed by material, therefore good than the effect that near infrared ray dries with far infrared drying.
The present invention utilizes the method that radiant heat transfer dries.Electromagnetic wave produced by carbon fiber far-infrared heat-generating pipe is propagated with the velocity linear of light and is arrived object to be dried, when the tranmitting frequency of carbon fiber far-infrared heat-generating pipe and the natural frequency of object to be dried Middle molecule motion match (in other words, the transmitting wavelength of carbon fiber far-infrared heat-generating pipe is consistent with the absorbing wavelength of object to be dried), the judder of object Middle molecule will be caused, at interior of articles generation severe friction, and then generation heat energy, reach the purpose dried.
