Online water measuring equipment for grain drying tower

Abstract

The utility model discloses online water measuring equipment for a grain drying tower. A plurality of drying air sections are arranged in a tower body of the grain drying tower; grain input pipes arearranged at the upper end and the lower end of the lowermost tail wind section respectively; the grain input pipe is transversely arranged inside and outside the tower body; a stranding cage is arranged in the grain input pipe; a plurality of grain input openings are formed in the pipe wall of the grain input pipe arranged in the tower body; a grain outlet is formed in the pipe wall of the grain input pipe arranged outside the tower body, a grain water meter is arranged below each grain outlet, the detection end of each grain water meter is connected with the corresponding grain outlet througha grain sliding pipe, a grain input motor is arranged outside the tower body and at the end part of the grain input pipe, and the grain input motor is in power connection with a stranding cage arranged in the grain input pipe; a plurality of grains are taken from the upper end and the lower end of the tail wind section and sent to a grain moisture meter for moisture detection at regular intervals; the real-time online moisture value is obtained, the grain moisture of the grain reaching the grain discharging position can be predicted in advance, then the temperature of the tail air section isadjusted, finally, the dried grain with the uniform moisture value is obtained, the finished product rate of the dried grain is increased, and grain storage is facilitated.

Description

technical field [0001] The invention relates to special auxiliary equipment for grain drying towers, in particular to online water measuring equipment for grain drying towers. Background technique [0002] The grain drying tower is equipped with multiple air sections from top to bottom, and the hot air is sent to each air section through the hot air pipeline to dry the grain in the tower. The temperature of the hot air in each air section passes through the air distribution door in the pipeline To adjust, when the opening of the air distribution door becomes smaller, the temperature in the corresponding air section will increase, and when the opening of the air distribution door becomes larger, the temperature in the corresponding air section will decrease, so as to dry different grains, The elevator transports the wet grain to the top of the drying tower and sends it into the tower. The grain is dried by each air section and then discharged by the grain discharge device. Th...

[0002] The grain drying tower is equipped with multiple air sections from top to bottom, and the hot air is sent to each air section through the hot air pipeline to dry the grain in the tower. The temperature of the hot air in each air section passes through the air distribution door in the pipeline To adjust, when the opening of the air distribution door becomes smaller, the temperature in the corresponding air section will increase, and when the opening of the air distribution door becomes larger, the temperature in the corresponding air section will decrease, so as to dry different grains, The elevator transports the wet grain to the top of the drying tower and sends it into the tower. The grain is dried by each air section and then discharged by the grain discharge device. The purpose of grain drying is to control the moisture content in the grain and facilitate grain storage. When drying the grain moisture, most of the grain samples are obtained at the grain discharge port of the grain discharge device, and the moisture value is measured. When the grain moisture value is high, the grain discharge speed is reduced by adjusting the speed of the grain discharge motor in the grain discharge device , to increase the residence time of grain in the tower, which is used to reduce the moisture value in the grain; when the moisture content of the grain is low, the grain discharge speed can be increased by adjusting the speed of the grain discharge motor in the grain discharge device, and the residence time of the grain in the tower can be shortened. It is used to reduce the volatilization of moisture in the grain; the disadvantage is: because it takes several hours for the grain to be put into the dryer until it is discharged, and the initial moisture content of the grain put into the tower is not the same, so at a constant temperature in the tower After the drying treatment, the moisture value of the discharged grain fluctuates greatly, resulting in uneven drying of the processed grain moisture.
