Since the loading amount of the double cone rotary vacuum dryer is related to the bulk density of the material (referring to the mass of the material per unit volume), in general, the material specific gravity is calculated as 0.6g/cm3 during design. If it exceeds this specific gravity, the material is still loaded according to the original theoretical amount in actual production, which will affect the drying efficiency of the material; secondly, long-term operation will reduce the life of the motor, reducer, sprocket chain, etc., until they cannot be used. In addition, some manufacturers, in order to pursue production and blindly operate workers, ignore the filling rate (the ratio of the actual loading volume to the drying cylinder volume), which leads to continuous equipment operation and product quality problems of the double cone rotary vacuum dryer. It is worth mentioning that the filling rate of the double cone rotary vacuum dryer is usually between 30% and 50%, and cannot exceed 60% at most.
If used improperly, the double cone rotary vacuum dryer may experience phenomena such as vacuum tube bending, sealing sleeve damage, filter head deformation and even breakage during the drying process. This is because the outside air (referred to as venting) is allowed to enter the tank body to recoil the filter head during the drying process. At this time, the tank body has reached a high vacuum degree, which will cause a strong impact of positive and negative airflows and damage the vacuum system.
It is worth noting that: after the material is dried, the tank body needs to be emptied. When emptying, the flow rate must be controlled by the venting valve, that is, first open the valve a little, and then slowly increase it after the vacuum degree in the tank gradually decreases.
During the drying process, the double cone rotary vacuum dryer often has insufficient or too high vacuum degree. This is usually due to three reasons:
(1) Leakage of mechanical seal at the vacuum end;
(2) Leakage or blockage of vacuum pipeline;
(3) Blockage of filter. This requires inspection during use, and maintenance, cleaning, etc.
(1) Excessive noise is caused by loose feet, damaged worm gear reducer, damaged bearing tube, loose or tight chain, etc. of the double cone rotary vacuum dryer. Just check regularly and eliminate the fault in time.
(2) Leakage at the inlet and outlet is normally caused by damaged sealing strips. Just replace them.
