Description
Technical field
The invention belongs to the dry field of eliminating liquid from solid material or goods, be specifically related to a kind of perpendicular box-type drying unit.
Background technology
Along with the improvement of grain kind, the raising of per unit area yield and country increase the investment of grain drying device, build the more and more of large, medium and small type grain heat-drying facility.Can match that quality is high, dryer that long service life, economical and practical, good reliability and automaticity are high is most important.
At present, the foodstuff drying device great majority of China are large-scale perpendicular chamber typed drying-machine, and version has cross-flow type and mixed-flow etc.Its main drying means is that Convective Heating is dry, and employing thermal current is drying medium, with convection type, heat is passed to cereal, and the steam of cereal evaporation is taken away, to reach dry object.The supporting thermal source of dryer mostly is coal-fired hot-blast stove or oil oven, and the thermal efficiency is lower, and specific energy consumption is higher, is difficult to meet environmental protection and dry the not contaminated requirement of grain.Adopt the thermal source that mechanical coal furnace and heat exchanger combine, though can meet the non-staining requirement of grain, the reliability of hot-blast stove is poor, efficiency is low, cost is high, the life-span is short; When adopting oil oven, often because quality nozzle does not pass a test, cause fuel atomization effect poor, burn insufficient, both caused the waste of fuel oil, caused environmental pollution again.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of drying efficiency high, the perpendicular box-type drying unit of environmentally safe.
For achieving the above object, technical scheme of the present invention is: perpendicular box-type drying unit, comprise casing, wherein, also comprise elevator, warehouse for drying and far infrared electro-thermal tube, described wall box offers steam vent, on described warehouse for drying, bottom is funnel-form, middle part cylindrically, described warehouse for drying is made up of sieve, also be provided with in warehouse for drying and surrounded by sieve, and the hot air chamber of all round closure, described far infrared electro-thermal tube is installed in hot air chamber, drying channel is formed between hot air chamber and warehouse for drying, be connected with elevator charging aperture by pipeline bottom described drying channel, described elevator discharging opening is positioned at above warehouse for drying.
When adopting technique scheme, grain adds in warehouse for drying, flow into the drying channel that warehouse for drying and hot air chamber are formed subsequently, continue to fall to bottom warehouse for drying, and flow into elevator charging aperture through pipeline, grain is promoted again the top being circulated to warehouse for drying by elevator, thus carry out cyclic drying, because hot air chamber is positioned at warehouse for drying, surrounded by sieve, and all round closure, so grain can not enter in hot air chamber, and far infrared electro-thermal tube is installed in hot air chamber, far infrared infrared heating pipe is outwards radiation infrared and add hot-air, hot blast is from hot air chamber to external diffusion, hot blast enters in drying channel, thus the moisture taken away in grain, because warehouse for drying is also for sieve is made, so hot blast can more easily from hot air chamber to external diffusion, the heat diffused in casing upwards flows, and enter the funnelform top of warehouse for drying, heating, drying can also be carried out to the grain on warehouse for drying top, Btu utilization is more abundant.The present invention utilizes far-infrared heating tube as heating source, and make it outwards radiation infraredly carry out heat drying to grain, compared with fuel combustion, can not produce air-polluting tail gas, be the energy comparing hygiene.In addition, warehouse for drying is made up of sieve, heat easily through, and far infrared has the fast feature of heating, so can improve dry efficiency.
Further, described hot air chamber top is coniform.The grain to be dried added like this can not accumulate on hot air chamber top, can be slides quickly in the drying channel between hot air chamber and warehouse for drying.
Further, the blower fan of air outlet towards far infrared electro-thermal tube is provided with in described hot air chamber.Blower fan can force the flowing accelerating hot blast, is taken out of by the moisture content in grain rapidly, can accelerate drying efficiency.
Further, the gripper shoe of supporting warehouse for drying top, bottom is respectively equipped with in described casing.Warehouse for drying top adds more grain to be dried usually, and the grain gravity in warehouse for drying is born in bottom, and gripper shoe is established respectively in warehouse for drying top, bottom all comparatively greatly in warehouse for drying top, the stressed of bottom, thus reduces warehouse for drying distortion.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation that the present invention erects box-type drying unit embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of perpendicular box-type drying unit, comprise casing 1, wherein, also comprise elevator 6, warehouse for drying 2 and far infrared electro-thermal tube 4, casing 1 sidewall offers steam vent, on warehouse for drying 2, bottom is funnel-form, middle part cylindrically, warehouse for drying 2 is made up of sieve 3, also be provided with in warehouse for drying 2 and surrounded by sieve 3, and the hot air chamber of all round closure, far infrared electro-thermal tube 4 is installed in hot air chamber, drying channel is formed between hot air chamber and warehouse for drying 2, be connected with elevator 6 charging aperture 61 by pipeline 5 bottom drying channel, elevator 6 discharging opening is positioned at above warehouse for drying 2.
In the present embodiment, hot air chamber top is coniform.The grain to be dried added like this can not accumulate on hot air chamber top, can be slides quickly in the drying channel between hot air chamber and warehouse for drying 2.
The blower fan of air outlet towards far infrared electro-thermal tube 4 is provided with in hot air chamber.Blower fan can force the flowing accelerating hot blast, is taken out of by the moisture content in grain rapidly, can accelerate drying efficiency.
The gripper shoe of supporting warehouse for drying 2 top, bottom is respectively equipped with in casing 1.Warehouse for drying 2 top adds more grain to be dried usually, and the grain gravity in warehouse for drying 2 is born in bottom, and gripper shoe is established respectively in warehouse for drying 2 top, bottom all comparatively greatly in warehouse for drying 2 top, the stressed of bottom, thus reduction warehouse for drying 2 is out of shape
Operation principle:
As shown in Figure 1, grain adds in warehouse for drying 2, flow into the drying channel that warehouse for drying 2 is formed with hot air chamber subsequently, continue to fall to bottom warehouse for drying 2, and flow into elevator 6 charging aperture 61 through pipeline 5, grain is promoted again the top being circulated to warehouse for drying 2 by elevator 6, thus carry out cyclic drying, because hot air chamber is positioned at warehouse for drying 2, surrounded by sieve 3, and all round closure, so grain can not enter in hot air chamber, and far infrared electro-thermal tube 4 is installed in hot air chamber, far infrared infrared heating pipe is outwards radiation infrared and add hot-air, hot blast is from hot air chamber to external diffusion, hot blast enters in drying channel, thus the moisture taken away in grain, because warehouse for drying 2 is also made for sieve 3, so hot blast can more easily from hot air chamber to external diffusion, the heat diffused in casing 1 upwards flows, and enter the funnelform top of warehouse for drying 2, heating, drying can also be carried out to the grain on warehouse for drying 2 top, Btu utilization is more abundant.
Above is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
