Description
Technical field
The utility model belongs to the equipment that the goods with progressive motion is carried out drying, particularly a kind of vortex multi-function drying machine.
Background technology
The oven dry of present domestic fruits and vegetables and marine product all is to do thermal source with pure hot blast basically, adopts the following current air supply mode, perhaps adverse current air supply mode, and the employing that also has crossing current air supply mode is dried.These air supply modes exist a common shortcoming to be: the drying materials inequality.Same batch materials, the partial material water content has reached standard, also has the water content of partial material still to exceed standard.At this moment, if stop oven dry, some material moisture is too high, does not reach quality standard, if continue oven dry, then partial material will overdrying, has both increased the oven dry cost, has reduced output again.The uneven main cause of oven dry is: air-supply is uneven.The same cross section that hot blast flows in dryer, the position hot blast amount of flow that has is big, and drying materials is just fast, and the position hot blast amount of flow that has is little, and drying materials is just slow.Figure 4 shows that dryer following current air supply mode: hot blast 19 enters dryer 1 by air inlet 18, after humidity discharging gas port 2 is discharged moisture 22.In dryer, hot blast 19 vertically flows, material bed height difference, and the air output difference, hot blast 19 all is directly to blow to material after entering dryer 1, therefore directly blows to the hot blast 21 of material part, and its hot blast amount of flow is big, and heat is also big, and drying rate is just fast; And the dryer upper and lower blows to the hot blast 20 of material, and its hot blast amount of flow is little, and heat is little, and drying rate is just slow, and it is uneven therefore to have formed air-supply; The little air output of dryer two collateral resistances is big, and resistance big air output in middle part is few, and it is uneven also to have formed air-supply, the problem that oven dry is uneven.
Be the air-supply of following current air-supply, adverse current, or all there is problem because of the uneven oven dry inequality that produces of blowing in the crossing current air-supply.
Summary of the invention
The purpose of this utility model is exactly to adopt air-supply of main air duct equal pressure and secondary air channel eddy current air supply mode to solve the problem of the uneven oven dry inequality of bringing of air-supply, thus reach improve the quality of products, output, reduce the purpose of drying cost.
The utility model has designed a kind of vortex supply air system---secondary air channel.As shown in Figure 3: secondary air channel is by the secondary air channel import 9 of steel plate, secondary blower fan 8, circular steel plate hot-blast pipe line 29, steel construction humidity discharging heater 30, circular steel plate damp air discharge pipe road 11, the independently hot blast closed cycle system that secondary ducting outlet 10 and dryer 1 are formed.Secondary air channel import 9 is at high point, and secondary ducting outlet 10 is installed in the same side of dryer 1 respectively at low spot, between air inlet 9 and air outlet 10 are horizontal certain spacing arranged.
The utility model has designed a kind of humidity discharging heater 30, and the humidity discharging heater also is the waste-heat recoverer of hot-blast stove.As shown in Figure 8: hot-blast stove chimney 31 usefulness ring flanges 36 are connected the top of hot-blast stove 42.The outer surface welding steel fin 33 of hot-blast stove chimney 31, steel cylinder 34 usefulness upper covers 37, low head 41 is welded on the chimney 31, forms the heat exchanger 44 of a sealing.Heat exchanger 44 usefulness steel plate bars 32 are separated into left and right sides two parts from the centre, air channel 43 is left on top.Hot-blast outlet 40 is installed in heat exchanger 44 left sides, and moisture import 35 is installed on the right side.
As Fig. 1, shown in Figure 3: the utility model has designed a kind of isobaric chamber 13.Isobaric chamber 13 is to go along with sb. to guard him the big bellows of not adorning any material that form by hot blast import 12, internal layer hot-dip galvanizing sheet steel 16 (or corrosion resistant plate), heat-insulation layer 14, outer color steel 15, and hot blast import 12 must be installed in the side of dryer 1.

The specific embodiment
As shown in Figure 7: the hot blast 25 from main air blower 7 outputs by the side of main air duct import 12 at dryer 1, enters isobaric chamber 13.Because isobaric chamber 13 is big bellows without any material and resistance, hot blast 25 enters isobaric chamber from the dryer side, directly do not blow to material, hot blast blast in isobaric chamber 13 equates, form isobaric wind 28, isobaric wind 28 is blown with 23 each material bed vertical flowing at dryer 1, for condition has been created in balanced ventilation as main.
The vortex supply air system is made up of secondary air channel.As Fig. 3, shown in Figure 7: the moisture that has reduced temperature 27 in the dryer 1 is drawn by secondary blower fan 8, the 11 input humidity discharging heaters 30 through the damp air discharge pipe road, in humidity discharging heater 30, through heat exchange, discharge section moisture, again moisture 27 is brought up to the temperature of requirement, re-entered dryer 1 as hot blast 26.Owing to secondary air channel import 9 with between exporting 10 difference in height and horizontal spacing are arranged, hot blast 26 is again lateral flow in dryer 1, so under the vertical effect of main air-supply with 23 isobaric wind, form gyrate wind band 24 by hot blast 26 and the isobaric wind 28 of part, in each material bed lateral flow of dryer.Gyrate wind band 24 has thoroughly solved the difficult problem of each uneven air between material bed, thereby has reached the purpose of even oven dry.
The embodiment of humidity discharging heater 30 such as Fig. 3, Fig. 7, shown in Figure 8: moisture 27 is introduced humidity discharging heater 30 through secondary blower fan 8, and moisture 27 moves 39 on a side direction of heat exchanger 44, wash away fin 33, fume afterheat is absorbed, moisture 27 has been removed part moisture in heated process, through upper air duct 43, move and be enhanced temperature downwards and become hot blast 38, through hot-blast outlet 40, re-enter dryer 1 again, lateral flow forms eddy current wind 24 in dryer.
As Figure 1-3: be contained in the drip pan 4 by the material of being dried, enter dryer 1 from end door 17, carrying drip pan 4 vertically move dolly 5, the order intermittence moves forward, after isobaric wind oven dry, the oven dry of eddy current wind, by horizontal travelling car 6, send dryer again from side door 3.
The utility model is compared than prior art has following characteristics:
In the main air duct, the hot blast 25 that main air blower is exported forms isobaric wind 28 in isobaric chamber 13, is with 23 as main air-supply, at each material bed hot blast that vertically flows, is air quantity, and blast equates the isobaric wind 23 of formation substantially, has reached the purpose of balanced ventilation.
In secondary air channel, the hot blast 26 of secondary blower fan output forms gyrate wind band 24, material bed lateral flow.Gyrate wind band 24 has thoroughly solved the difficult problem of each uneven air between material bed, thereby has reached the purpose of even oven dry.
