Automatic thermoregulator device of grain drier

Abstract

The invention discloses an automatic thermoregulator device of a grain drier. The automatic thermoregulator device comprises a hot air lock device, a hot air pipe, a cold air inlet volume control mechanism and a flow guide mechanism, wherein the hot air lock device is connected with the hot air pipe; the hot air pipe is connected with the cold air inlet volume control mechanism; the flow guide mechanism is connected with the hot air pipe, and is further connected with the cold air inlet volume control mechanism; a shaft hole is formed in a stroke motor base of a hot air barrel shell of the hot air lock device; the shaft hole goes through the hot air barrel shell and is connected with a circular shaft; the circular shaft is connected with a stroke motor; the stroke motor is fixedly connected with the stroke motor base; the other end of the circular shaft is connected with an indicating arrow; and the circular shaft inside the hot air barrel shell is connected with an air door plate. According to the automatic thermoregulator device, when the grain drier performs drying operation, the automatic thermoregulator device enables the temperature control accuracy to reach + / -1 DEG C, and the accuracy is improved by 2 to 4 times compared with the accuracy of a device which has no thermoregulator and has the same power; and through the utilization of the automatic thermoregulator device, two operators are saved for each operation team, and the fuel can be saved by 5 to 10%.

Description

technical field [0001] The invention relates to the technical field of grain machinery, in particular to an automatic temperature regulator device for a grain dryer. Background technique [0002] my country has a vast territory, with large temperature differences between north and south latitudes and large differences in precipitation between east and west longitudes. In addition to the differences in geographical topography, the natural moisture content of grains during harvest is very different. When drying grain after harvest, the low-temperature circulation grain dryer has different requirements for the air volume, wind pressure, and temperature of the hot air provided by the hot blast stove. Among them, the temperature index is the key to the quality of grain drying and the efficiency of drying operations. one of the factors. [0003] Previously, the air inlet temperature control of the dryer relied on the manual control of the furnace temperature of the hot blast stov...

Problems solved by technology

[0003] Previously, the air inlet temperature control of the dryer relied on the manual control of the furnace temperature of the hot blast stove and the control of the air intake volume of the hot air. Influenced by factors such as slow reaction speed, the temperature control accuracy is low, and the general temperature control accuracy is ±3-5°C
