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. Th...

Abstract

The invention discloses a spiral plate type hot blast stove which comprises a spiral plate type heat exchanger, a hot blast stove shell and a hearth for heating. The spiral plate type heat exchanger comprises an upper spiral heat exchanger, a lower spiral heat exchanger, two upper spiral plates, two lower spiral plates and a center pipe. When airflow to be heated flows into the stove from an opening of a spiral channel of the upper / lower spiral heat exchanger and flows out of the stove from an opening of a spiral channel of the lower / upper spiral heat exchanger after flowing through spiral channels of the upper spiral heat exchanger and the lower spiral heat exchanger. Hot airflow for heating upwards flows into the stove from the adjacent spiral channels of the upper spiral heat exchanger and the lower spiral heat exchanger, and two paths of airflow in the spiral channels flow along the spiral channels in an adjacent manner for transferring heat to inflowing airflow to be heated; and a radiation and convection principle is adopted for heat exchange, and it is guaranteed that materials are dried through clean heat air. The invention further discloses the cyclone type flashing drying machine for oilseed rapes and with the spiral plate type hot blast stove.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a spiral plate hot blast stove and a rape cyclone flash dryer using the hot blast stove. Background technique [0002] The waste of rapeseed due to mildew in the storage of rapeseed is very serious. Since the rapeseed is harvested in 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 enterpris...
