As shown in Figure 2,4, in the housing of gas-liquid heat exchange of heat pipe, be provided with the gravity type heat pipe 211 that multiple row Vertical dimension is laid, also be provided with the diaphragm plate 216 heat exchanger condensation end 214 and evaporation ends 215 separated, heat pipe front-back staggered arranges, all through diaphragm plate, and the heat pipe periphery being positioned at diaphragm plate epicoele is provided with many group fins 217.One end of gas-liquid heat exchange of heat pipe diaphragm plate epicoele, is provided with air intlet 218, and the other end is provided with pre-hot-blast outlet 219.
As shown in Figure 3,4,
In the housing of gas gas heat exchange of heat pipe, be provided with the gravity type heat pipe 221 that multiple row Vertical dimension is laid, be also provided with the diaphragm plate 226 heat exchanger condensation end 224 and evaporation ends 225 separated, heat pipe front-back staggered arranges, and all through diaphragm plate.And the heat pipe periphery of diaphragm plate upper and lower cavity is equipped with many group fins 227.One end of the diaphragm plate epicoele of gas gas heat exchange of heat pipe, be provided with the air inlet 228 that hot-blast outlet 219 pre-with gas-liquid heat exchange of heat pipe communicates, the other end is hot-blast outlet 229, be communicated with by the hot wind inlet of ajutage with dehumidification drying device drying chamber lower portion, one end of its diaphragm plate cavity of resorption, be provided with the high-temp waste gas import 222 communicated with harvester tail gas outlet, the other end is provided with low temperature waste gas outlet 223.
As shown in Figure 5,
Vibrating motor 32 outside dehumidification drying device drying chamber 31 produces exciting source, and be connected to the vibrating 33 in drying chamber by output shaft, vibrating is connected with perforated distributor body 34.The top of drying chamber, corresponds to perforated distributor one side and is provided with the blanking window 35 entered for cereal 6; And perforated distributor is the shape that has a down dip of 1-10 °; This drying chamber corresponding position, side that has a down dip is provided with discharging opening 36, and discharging opening is provided with gate valve 361.The lower portion of drying chamber is provided with high hot wind inlet 38, lingering remnants of past customs outlet 39; Drying chamber be provided with discharging opening 37 for subsequent use bottom, and switch valve 371.
The present invention is according to technical scheme and above-mentioned detailed description of the invention requirement, select the perforated distributor in certain aperture according to harvesting grain granular size, and with suitable tilt angled down install appropriate after, can the harvester of cooperating state, carry out the real-time removal moisture drying of cereal, its process is as follows:
The air circulation that cfentrifugal blower produces is crossed ajutage and is entered gas-liquid heat exchange of heat pipe, the hot water flowing to heat exchanger with harvester water-cooling apparatus carries out heat exchange, because the fin of gravity type heat pipe and periphery thereof has good endothermic effect, the air stream entering heat exchanger is made to obtain preheating, pre-heated air flow enters gas gas heat exchange of heat pipe, carry out second time heat exchange arranging with harvester tail gas discharging pipe the high-temperature tail gas entering this heat exchanger, pre-heated air flow obtains and obviously heats up, the air stream of high temperature enters from dehumidification drying device drying chamber bottom and upwards runs, through the hole of perforated distributor, slowly the fresh cereal fallen with drying chamber blanking window fully contacts, again because perforated distributor is at vibrating motor, again and again vibrate under the control of vibrating, cereal is heated and dehumidified drying under the suspended state of spring, and concentrate discharging to porous sieve plate downdip direction, so go round and begin again.
When native system uses, in case of outside air is moist, also air dryer can be started; As once under occurring that second time heat exchange hot blast temperature does not reach expection situation, also can start electric heater and assist raising to enter the hot blast temperature of dehumidification drying device again.Separately, native system maybe can adopt intelligent control technology, arranges epidemic disaster and the components and parts such as wind speed, air flow sensor in the assembly region of interest of system, realizes automatically or artificially regulates job parameter, to obtain the real-time best removal moisture drying effect of cereal.
To sum up, the present invention can reach the goal of the invention of expection.
