Cement Clinker Manufacturing Process Machine dumping phenomenon
The phenomenon of Cement Clinker Manufacturing Process Machine dumping is mainly because the amount of material in the hopper increases with the demand of the enterprise. In the process of unloading, the material is too late to be taken out from the hopper and brought to the receiving plate. The material of the hopper does not fall.
The time taken to slide this distance has exceeded the time taken by the hopper from A to B, and thus the returning phenomenon has occurred. The material that has not been cleaned is scattered to the Cement Clinker Manufacturing Process Machine casing and then dropped to the end of the machine and re-examined to the nose, so that the cycle is poor until the casing is worn.
When checking the dumping at the manhole door at the discharge end of the head of the Cement Clinker Manufacturing Process Machine, it was found that the back of the hopper also acted as a receiving plate when the material was brought to the head by the hoist to the falling material. During the process of starting the unloading of the hoist to the receiving plate, when some of the material falls to the back of the hopper and slides down, it is brought into the casing below the receiving plate because it does not fall onto the receiving plate, so wear occurs. phenomenon.
So what are the treatment methods? Please see the analysis of Shanghai Shibang:
Treatment plan 1: Replace the lower part of the lifting plate of the lifting machine. Since the angle of the lifting machine can not change, the lowering of the receiving plate is limited, only 300mm can be moved, the effect is not obvious.
Due to the problem of pouring, the hoist casing is worn through, the hopper and the chain connecting screw are worn away, and the thickness of the edge of the chain chain is 2 mm, and the interface screw of the chain is worn away by half. In severe cases, the plates are disconnected, the hopper is removed, and the lower sprocket of the hoist is out of the groove.
Treatment plan 2: Extend the blanking time. The hoist is driven by a 4-pole motor, the speed ratio of the reducer is i=21.5, the diameter of the upper sprocket is 1 meter, and the running speed of the hoist is calculated to be 67.51 m/min, which is 1.125 m/s. The distance from the receiving plate to the nose hopper is 3 meters. Therefore, the Cement Clinker Manufacturing Process Machine hopper needs 2.66 seconds to run at this distance. We installed a 1 m new casing on the original casing above the receiving plate. This extends the blanking time by 0.35 seconds. The calculation formula is as follows:
S=V0t+0.5gt2 is known: V0=1.125, g=9.8, S=1
Substituting the formula to calculate: t = 0.35 (seconds)
The above is the reason and treatment method of the Cement Clinker Manufacturing Process Machine dumping phenomenon introduced by Shanghai Shibang. If you have any questions, please consult us directly!
