Description
Technical field
The utility model relates to a kind of heated-air circulation oven, especially a kind of heated-air circulation oven that is fit to high water-bearing solid material oven dry.
Background technology
Heating tube is generally arranged, circulating fan is arranged, no matter air supply mode is level or vertical, so long as hot blast all can be described as heated-air circulation oven at the baking oven of casing the inside circulation.
Because baking oven has the uniform specification requirement of heat distribution, there is intrinsic structural defect in the vertical ventilation mode, and therefore, heated-air circulation oven substantially all adopts the horizontal blast mode, the hot blast that level is sent and material surface heat exchange add thermal material and take away moisture, are used for hot air sterilization or the drying of material.Such as Fig. 1 and shown in Figure 2, the heated-air circulation oven of existing horizontal blast mode, comprise casing 1, be provided with circulating fan 2 in the described casing 1, heater 3 and drying chamber 4, described drying chamber 4 is by top board 40, base plate 41, left deflector 42 and right deflector 43 enclose and form, described left deflector 42 is the air-out deflector, described right deflector 43 is the air intake deflector, described left deflector 42 and right deflector 43 are comprised of a plurality of horizontally disposed dividing plate 100 longitudinal arrangements respectively, leave gap 101 between adjacent two dividing plates 100, the gap 101 of the right and left one by one corresponding and institute gapped 101 width all, be placed with material bearing support 5 in the drying chamber 4, be placed with material loading tray 6 on the described material bearing support 5.Its drying course is roughly as follows: circulating fan 2 imports dry wind in the casing 1 by the air inlet 20 at casing 1 top, then heater 3 adds the thermosetting hot blast with the dry wind that imports, hot blast enters in the drying chamber 4 by the gap 101 on the right deflector 43 and the materials in the material loading tray 6 is dried and forms steam, and then by the gap 101 discharge drying chambers 4 on the left deflector 42, finally discharge outside the casings 1 by the air outlet 21 at casing 1 top.There is following defective in the heated-air circulation oven of this structure: because thermal current has the characteristic of rising, therefore easily be gathered in the top in the drying chamber 4, trend towards forming saturated vapor, affect the oven dry of upper materials, and because the width in gap 101 is all the same, cause upper strata steam to be difficult to get rid of, easily form saturated vapor pressure, drying effect and the Drying Rates of upper materials and lower floor's material differ greatly, thereby have greatly prolonged drying time, increase the oven dry energy consumption.The heated-air circulation oven of this structure is only applicable to the material of low water content, equipment can satisfy the heat distribution requirement in unloaded or fully loaded low water-bearing solid material (approximately moisture 20%) situation, and water evaporation quantity is few, rises even hot blast is a small amount of, also moisture can be taken away fully, do not affected drying; But when the high water-containing materials of oven dry (moisture is greater than 20%), be warming up to a certain degree (approximately 70 ℃) with baking oven, moisture begins a large amount of evaporations, and casing can not be taken away and discharge to hot blast fully, and these vapours transpirations also are gathered in casing top, form saturated vapor, affect the drying of upper materials, causing wets does down the defective that dry materials is inhomogeneous, and for the drying that guarantees upper materials prolongs drying time, reduced drying efficiency.
The utility model content
In order to overcome the defective of above-mentioned prior art, it is high and dry uniform heated-air circulation oven that technical problem to be solved in the utility model provides a kind of drying efficiency, is particularly suitable for the oven dry of high water-bearing solid material.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of heated-air circulation oven, comprise casing, be provided with circulating fan, heater and drying chamber in the described casing, described drying chamber is enclosed by top board, base plate, left deflector and right deflector and forms, described left deflector is the air-out deflector, described right deflector is the air intake deflector, described left deflector and right deflector are comprised of a plurality of horizontally disposed dividing plate longitudinal arrangements respectively, leave the gap between adjacent two dividing plates, gap on the described right deflector broadens from top to bottom gradually, and the gap on the described left deflector narrows down from top to bottom gradually.
Wherein, the gap on described left deflector and the right deflector is respectively 12, the gap width of the lowermost end on the described left deflector be top gap width 1/3, the gap width of the top on the described right deflector be lowermost end gap width 1/3.
Wherein, also comprise material bearing support and material loading tray, described material loading tray places on the described material bearing support, and the bottom of described material loading tray is netted, and described material bearing support places in the described drying chamber, and the bottom of described material bearing support is provided with roller.
The utility model is left by changing, gap width on the right deflector, the gradient of increase distributes to make the air intake flow be from top to bottom successively, air-out flow is the gradient that reduces successively from top to bottom and distributes, the air intake flow of drying chamber inner bottom part is large and air-out flow is few, impel the hot blast of drying chamber inner bottom part to flow to the top, thereby the hot blast in the drying chamber is evenly distributed, drying materials is also more even, flowing of hot blast also accelerated the Drying Rates of material, and since vapours more near the top of drying chamber, gap on the left deflector (air-out deflector) is also larger, the discharge rate of vapours (air-out flow) is also larger, so that the formation saturated vapor pressure is gathered at the top that vapours is difficult in drying chamber, the drying materials speed of drying chamber top and bottom is more consistent, and drying effect is more approaching.
Take the material of dry water content 50% as example, proof by experiment, heated-air circulation oven of the present utility model is compared with existing heated-air circulation oven, has at least following advantage:
1, be difficult for forming saturated vapor pressure: the temperature that the utility model forms saturated vapor pressure is about 80 ℃, and the temperature of existing heated-air circulation oven formation saturated vapor pressure is about 70 ℃;
2, oven dry is more even: when being dried to water content 13%, levels material moisture maximum of the present utility model differs approximately 4%, be lower floor's moisture minimum be 11%, upper strata moisture is the highest to be no more than 15%, and the levels material moisture maximum of existing heated-air circulation oven differs and can reach 10%, be lower floor's moisture minimum be 8%, the upper strata is up to 18%;
3, drying efficiency is higher, and is more energy-conservation: when being dried to water content 13%, adopt the utility model can shorten drying time approximately 15%, energy efficient 10%.
