Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] see Figure 1 to Figure 12 The cyclone flash dryer for rape in this embodiment includes a frame 1, a frequency conversion motor 2, a high-pressure centrifugal fan 3, a belt transmission group mechanism 4, a spiral plate type hot blast stove 5, a screw type K-type M6 metric thermocouple 6, a valve type Feeder 7, dryer 8, cyclone receiver 9, star unloader 10. The belt transmission group mechanism 4 includes a belt 42 and a shaft coupling 41. The casing of the shaft coupling 41 is semicircular and the rectangular plates at the extensions on both sides are screwed to the frame. The shaft of the motor 2 is connected, and the other side shaft is fixedly connected with the inner impeller 31 of the high-pressure centrifugal fan 3 . The high-pressure centrifugal fan 3 includes an impeller 31, a fan support 32, a fan casing 33, and a fan inlet pipe 98. T...

Abstract

The invention discloses a cyclone type flashing drying machine for oilseed rapes. The cyclone type flashing drying machine comprises a drive mechanism, a high-pressure centrifugal fan, a spiral-plate type hot blast heater, a valve type feeding device, a drying device, a cyclone collection device and a star-type discharging device. An air outlet of the hot blast stove is connected with the lower end of a pipe of the valve type feeding device and an inlet of an annular channel at the bottom end of a drying cylinder. The top of the cyclone collecting device is provided with a spiral airflow inlet pipe and an air guide and outlet pipe which are connected with the drying device and an inlet pipe of a fan. The lower end of the cyclone collection device is connected with the star type discharging device through a trapped pipe on the lower portion of the cyclone collection device. The spiral plate type hot blast stove comprises a spiral plate type heat exchanger which is provided with at least a pair of spiral channels arranged in a spaced manner so that cold fluid and heat fluid can flow helically and flow upwards in two runners respectively. By means of the structure, the heat utilization rate is high, and clean airflow can be obtained; meanwhile the valve type feeding device is adopted, no devices for stirring, chopping and the like are adopted, and the quality and integrity of material particles in the feeding and drying processes when the drying machine operates are guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a cyclone flash dryer suitable for granular materials such as rapeseed. Background technique [0002] The waste of rapeseed due to mildew in the storage of rapeseed is very serious. Because the rapeseed harvest is the rainy season in the Yangtze River Basin, the moisture content of the harvested rapeseed is between 15% and 30%, the particle size of the rapeseed is 1.27-2.10mm, the gap between the particles is small, the heat transfer is slow, and it is not easy to lose heat. Water, plus high respiratory intensity, is prone to heat and mildew, so freshly harvested wet rapeseed must be properly dried before it can be safely stored. The efficiency of traditional natural drying of rapeseed is very low, and the process of stacking, spreading, and transporting rapeseed requires a lot of manpower, which increases the cost burden of rapeseed processing enterprises. Therefore, the ...
