5.3.1 When the dryer or the lower part is loaded with grain, the upper part is loaded with grain to be dried. If there is a smoke gun, all of them can be loaded into the wet gun, and the lower wet 1.$/T 12052002
shuttle is discharged and the high-speed drying should be carried out. When the dryer discharges the dry grain, the drying system should be stopped immediately and the continuous drying should be started. 5.3.2 When the loading height reaches the upper and lower positions, the grain system should be automatically stopped and the grain shaker should be turned on. 5.3.3 Control and adjustment of processing
The frequency converter of the grain discharge mechanism or the single-phase motor should be used to adjust the processing quantity. 5.3.3.1 Rotary grain discharge mechanism, adjust the speed. The higher the speed of the wheel, the faster the grain discharge speed and the larger the processing volume; on the contrary, the smaller the grain discharge speed. 5.3.3.2 Non-plate type grain discharge mechanism. The following two types of settings are adopted: 1) The reciprocating motion rate of the discharge plate is low. The higher the rate, the faster the grain discharge speed and the larger the processing volume; on the contrary, the smaller the grain discharge speed. 2) Adjust the interval between the discharge plate and the grain level. The larger the interval, the faster the grain discharge speed and the larger the processing volume; on the contrary, the smaller the grain discharge speed. 5.3.3.3 The grain discharge mechanism of the plate type is the grain discharge plate: the larger the number of revolutions, the larger the processing volume; on the contrary, the smaller the processing volume. 5.3.4 Determination of moisture content of grain

The machine with a depth of more than 100℃ or more than 100℃ for a long time: The machine should be handled according to the following two methods. 6.3..1 When the machine is in the machine! And the amount of grain in the store tower temperature: from front to back according to the disaster to close the drying machine before the equipment: up) if the block below the stable food gradually empty, the user above the hot air Kai equipment into the air room 1. Step by step to reduce the amount of coal added to the hot air furnace: keep the cooling fan open, until all the food is evenly discharged from the drying machine: practice? Ai cut the grain discharge mechanism of the dryer first, turn off the cold air fan: from the back you turn off the idle dryer after the conveying, cleaning equipment: F
meaning of the system:
stop expansion, the temperature on the rest of the big!
6.2.2.2 When only the collecting tower is left in the machine, a series of methods can also be used: a) Use cannon to extinguish the remaining fire in the furnace:
b) Close the initial point and change the grain feeding;
Drain all the food:
d) Shut down the drying machine and its auxiliary equipment;
) Non-grain treatment
6.3.2.3 When there is only moisture in the machine, use a cannon to extinguish the remaining fire in the furnace:
b) Close the initial point and change the grain feeding;
D) Shut down the drying machine and its auxiliary equipment;
) Non-grain treatment
6.3.2.3 When there is moisture in the machine! The last tower of the hot blast furnace is used to carry grain. After the lights are turned off, the hot air blower is equipped with a damper to use the residual heat in the hot air to dry the grain. After the grain is dried, it is discharged. The operation of the hot blast furnace is completed. 7.1 Basic requirements. The hot blast furnace meets the requirements of IBT6. 7.2 Inspection before baking. The operator should conduct a comprehensive inspection of the hot blast furnace and its auxiliary equipment. The inspection is as follows: The guard plate is in good condition with the sprocket. It rotates smoothly at the staggered wheel shaft. 2. The grate plate is connected to the furnace. If the two sides of the grate are not in order with the furnace body, there will be a phenomenon of disorder. The guard plate is damaged and the silicon is damaged. The damaged parts should be replaced in time! 6. Install the bolts on the left car, and clean up the metal debris such as nails and butt heads; the water gate should be closed with a flexible material, and the lower edge should be parallel to the working surface of the grate; the cover plate should be sealed: settling chamber. heat exchanger: virtual closing pressure or cultivation: the motor shaft should be lubricated with oil (grease): blower. induced draft fan, and the coal blower and outlet fan should be checked to be in normal operation. 7.3 Drying furnace
