Description

[Detailed description of the invention] Industrial applications The present invention relates to a voice control device for a grain dryer.

Conventional technology Conventionally, when an abnormality occurs in each part of a dryer, each sensor installed in each part detects the abnormality, and the abnormality detected by each sensor is used to start and stop the dryer. It is configured to display on the operating device etc. that performs operations such as, etc., and it is not possible to issue an audible alarm to the abnormality detected location, or to confirm the abnormality detection location detected by each sensor using an intercom etc. It was a grain dryer.

Problems to be Solved by the Invention Since the grains stored in the dryer are not repeatedly circulated within the dryer, they are exposed to hot air generated from a burner and dried, and during this drying operation, the grains generated from the burner are dried. A flame sensor that detects the combustion flame, a hot air temperature sensor that detects abnormal hot air temperature generated from this burner, a grain flow sensor that detects the flow of circulating grains during drying, and a suction air that is sucked and discharged by an exhaust fan. When an abnormality is detected by the airflow sensor and each of these sensors, the location of the abnormality is displayed on the display window of the operating device that starts and stops the dryer. The installation location is a workplace, and drying work is often done at night, so workers are often not in the workplace where the dryer is installed. Since this information cannot be known, the dryer may be left in a state where it automatically stops for a long time, resulting in a significant drop in grain drying efficiency, or the dryer may be stopped for a long time while drying high-moisture grains. If the grains were left untreated, the grains being dried in the dryer would become stuffy and the quality would deteriorate.

Means for Solving the Problems This invention provides a flame sensor (2) for detecting the presence or absence of combustion flame generated from a burner (1), and a grain flow sensor for detecting the presence or absence of a circulating grain flow during circulating drying. (3), an air volume sensor (5) that detects the presence or absence of dry air sucked and exhausted by the exhaust fan (4), and a hot air temperature sensor (6) that detects abnormal hot air temperature generated from the burner (1), etc. When an abnormality is detected by each of these sensors (2), (3), (5), and (6), the audio alarm device (7) issues an audible warning to the location where the abnormality has occurred, and an intercom (8) When it is confirmed by the sound whether or not each sensor (2), (3), (5), (6) has detected an abnormality, the sound alarm device (
In 7), there is provided a voice control device for a grain dryer characterized in that an alarm control device is provided to issue an alarm at a location where an abnormality has been detected.

Effect of the Invention The grains housed in the dryer are dried by being exposed to hot air generated from the burner (1) while repeatedly circulating in the dryer, and during this drying operation, combustion flame is emitted from the burner (1). When the combustion flame is no longer generated, the flame sensor (2) detects it, and the combustion flame generated from this burner (1) is sucked by the exhaust fan (4) and becomes hot air.If the temperature of this hot air becomes abnormally high, this A hot air temperature sensor (
6) detects it, and when the exhaust air (4) stops sucking outside air, the air volume sensor (6) detects it, and when the grains stop circulating in the dryer, the grain flow sensor (3) detects it. However, when each of these sensors (2), (3), (5), and (6) detects an abnormality, the alarm control device controls the audio alarm system M (7) at the location where the abnormality is detected, and this audio alarm system (7
), and when the intercom (8) confirms whether or not each of the sensors (2), (3), (5), and (6) has detected an abnormality, the alarm control device The voice warning device (7) is controlled by the voice warning device (7).
In step 7), if an abnormality is detected at a location, an audio warning is issued.

Effects of the Invention According to the present invention, each sensor (2), (3), (5), (6) installed in the dryer to detect an abnormality during grain drying operation can be used.
) detects an abnormality, it will issue an audible warning to the location where the abnormality has been detected using the audio alarm device (7), or an intercom (8).
) to each sensor (2), (3), (5), (
6) confirms whether or not an abnormality has been detected, and if there is an abnormality detected by the voice alarm device (7), the drying operator will be alerted to the detected abnormality by sounding the abnormality. Even if you are located far away, you can immediately know if there is an abnormality in the dryer, so you no longer have to leave the dryer automatically stopped for long periods of time, which improves drying efficiency and improves grain quality. The drying operation becomes convenient because the drying temperature does not decrease and it is possible to check whether or not an abnormality has occurred.
