With the continuous upgrading of industrial equipment, grain steel silo are basically equipped with automatic dryers. In this way, grains can be directly dried and stored in the warehouse after harvesting, saving a lot of manpower and time. However, sometimes we find that the grains stored in the warehouse are not dried very thoroughly. Long-term storage in the range will cause mold, which brings serious safety hazards to grains. Today we will explain to you the six reasons why leisure grains in steel silos are not dried thoroughly.
In the actual application of grain dryers, one of the most common problems is the unqualified quality of grain drying. There are two specific manifestations. One is that the moisture content of rice is uneven after drying, some with high moisture content and some with low moisture content: the other is that after the rice is dried, the overall moisture content is still too high and does not meet the requirements of safe storage.
The main reasons for uneven moisture content in rice are: first, there is a huge difference in the moisture content of the raw grain itself; second, during the application of the grain dryer, the temperature of the hot air is unstable, the fluctuation is too large, and the temperature is sometimes high and sometimes low, which causes uneven moisture in the rice; third, there are problems with the grain discharge mechanism of the grain dryer, the grain discharge gaps are of different sizes and not uniform, which eventually leads to uneven moisture in the rice; fourth, there is a local blockage problem in the grain discharge mechanism of the grain dryer, which affects the drying quality; fifth, the hot air coverage is uneven, some parts can be blown, and some parts cannot be blown, which eventually causes uneven moisture in the rice; sixth, there is a blockage problem at the exhaust port of the exhaust chamber of the grain dryer, or the area is too small, which affects the drying quality and causes uneven moisture.
For the problem of uneven moisture in the grain dryer, the main solution is to grade the wet grain, stack it separately according to the level, and dry it in batches when drying. In order to maintain the uniformity of moisture, generally speaking, the moisture difference should not exceed 3%, preferably below 2%, so as to effectively ensure the storage safety of grain. In the process of using the grain dryer, the hot air furnace must be operated strictly in accordance with the operating procedures. If there is a gap problem with the grain discharge mechanism, it is necessary to stop the machine to adjust and repair the grain discharge mechanism. Ensure the uniformity of the gap. If there is a blockage problem, it is necessary to stop the machine to clean the blocked part. In addition, according to the actual situation, the performance of the grain dryer can be effectively adjusted by increasing the area of the air guide plate and the exhaust port, so as to ensure the uniformity of the moisture content of the rice after drying, so as to store grain more safely. If the overall moisture content of the rice is too high after drying, this may be caused by insufficient heat supply. Therefore, it is necessary to effectively control the production capacity of the grain dryer and adjust the heat supply.
Uneven grain discharge is also one of the common phenomena of poor drying effect of grain dryers. The main reason for uneven grain discharge is that there is a blockage problem between the six impellers and the side grain distribution plate of the grain dryer, or the gap between the six impellers and the side grain distribution plate is inconsistent and uneven. The solution to this problem is: if there is a blockage problem, stop the machine for cleaning to ensure the smooth flow between the six impellers and the side grain distribution plate. In view of the problem of uneven grain discharge gap, the grain discharge gap is adjusted to ensure that its size is consistent.
In the process of using the grain dryer, the simplified body causes the roller ring to swing during operation, which is also one of the more common problems. The main reason for this failure is that the side of the concave joint of the roller ring is not clamped. For this reason, the electric plate can be used to adjust and process the joint between the roller ring and the concave so that it can always remain uniform. At the same time, the side is tightened with appropriate force to prevent the swing problem caused by too loose. It should be noted that too much force should not be used during the clamping process to prevent the side of the concave joint of the roller ring from being too tight, and then safety accidents will be caused by its lack of flexibility during the application of the grain dryer.
In the process of using the grain dryer, wear and tear will inevitably occur. Even if the staff operates or keeps it improperly, it will cause damage to the grain dryer. Therefore, mechanical wear is one of the main reasons for the poor drying effect of the grain dryer. Among them, the destruction of the meshing clearance of large and small gears is its main symptom. During the long-term mechanical wear process, the tug and the stopper of the grain dryer will be affected to a certain extent, and there will be traces of wear. In addition, the small gear of the grain supply machine will also wear, which will cause the meshing gap between the large and small gears to become larger, seriously affecting the meshing effect of the large and small gears, and then affecting the drying effect of the grain dryer. In view of this problem, in order to effectively solve the problem of the meshing gap of the large and small gears being destroyed, it is necessary to combine the actual situation, mainly to observe the degree of wear of the large and small gears. If the wear is too heavy, it is necessary to directly replace the gears: if the wear is light, only the gear needs to be turned to change the meshing gap between the large and small gears, thereby improving the drying effect of the grain dryer. In addition, according to the specific situation, the upper boundary can also be installed on the reverse side or updated in pairs, which can effectively solve the problem of poor drying effect caused by the destruction of the meshing gap of the large and small gears, and effectively improve the drying quality of rice.
Vibration of the whole body is also one of the more common problems in the actual application of the grain dryer. The main cause of this failure is usually caused by damage to the connection between the tug device and the base. In addition, if the side of the roller of the grain dryer causes serious wear during long-term use, it will also cause the problem of whole-body vibration.
For the cause of the whole-body vibration of the grain dryer, the main solution is to tighten and correct the connection between the tugboat device and the base to ensure the correct position of the connection between the tugboat device and the base. For the wear problem of the side of the roller, different treatment methods should be adopted according to the actual situation. If the wear is serious, it needs to be replaced directly: if the wear is light. The roller needs to be turned to restore its normal function and eliminate the whole-body vibration problem of the dryer.
In the long-term application of the grain dryer, in addition to causing wear of the gears and rollers, it will also affect the cylinder, causing deformation of the cylinder, and then cracking of the weld of the cylinder, and then causing weld leakage. In addition, the inspection work is not in place when purchasing the grain dryer, and the gap of the cylinder weld is not found in time, which leads to weld leakage. This is also one of the common reasons for leakage of the welding gap of the grain dryer.
Regarding the problem of leakage in the welding gap of the cylinder, if it is a procurement quality problem caused by not checking in detail during procurement, it is necessary to find the manufacturer for repair or replacement; if it is a gap leakage problem caused by illegal operation, it is necessary to ask the manufacturer to recalculate the wind pressure, and at the same time carefully study the equipment manual, master the correct use method, and operate the grain dryer in a standardized manner; if it is a problem of wear and tear due to long-term use, it is necessary to replace or repair it according to the actual situation.
The above are the six reasons why the leisure grain in the grain steel silo is not completely dried. I hope it will be helpful to everyone when using Shandong steel silo in the future.
