Brief Instruction of Rotary airlock
Rotary airlock is an important device for pneumatic conveying and dust removal. The main usage of rotary airlock is to timely and constantly unload the material from discharger or dust collector, and to prevent the outside air from entering the discharger or dust collector. Rotary airlock can handle materials in powder, pellet, flake shapes and also fiber materials. And at the same time, rotary airlock is widely used in rice milling, powder, animal feed, machinery, chemical engineering, medicine, tobacco, metallurgy and cement making, dust removal and many other industries.
Structure and Working principle of Rotary airlock
This rotary airlock is a kind of improved impeller open type rotary vane feeder. It is a discharging machine structured with impeller, bearing, oil seal, air lock shell, end cover and other spare parts. On the top of the rotary airlock there is flange connected with the unload opening of discharger to receive the material from discharger, and then unload material from the bottom of rotary airlock while impeller rotating. The impeller is open type, which can prevent material from blocking as well as reduce air lock weight and shape.
Model Selection for Rotary airlock and Using Form
Model selection basis for rotary airlock
1. Material granularity (powder or granule);
2. Material viscosity(water or other liquids included);
3. Material pH value(may select common material or stainless steel with different properties);
4. Material temperature(select external type air lock above 60°C);
5. Material handling capacity(Theoretical calculation of volume×1.2).
Using form for rotary airlock :
Independent work by single rotary airlock( transmission by belt, chain or direct coupling), multi-machine series and in parallel. No more than 5 rotary airlocks in one unit when working by multi-machine in series or in parallel. The length of tandem shaft coupling and the height of bracket can be decided by users.
Installation and Use for Rotary airlock
Before installation rotary airlock must be carefully examined to make sure the impeller rotates flexibly and that relevant connecting parts reliable and correct. Then fix the rotary airlock on the floor or the bracket. Add full oil according to the using instructions if there is a reducer (3# Lithium-based lubricant). If a combination of rotary airlock are used, there must be overload and short-circuit protection devices in order to prevent the damage of motor.
Before feeding, rotary airlock with separate power must be turned on before host machine, while rotary airlock without separate power should be turned on with host machine at the same time. And rotary airlock should be shut down after discharging of raw material.
Always pay attention to the observing window to see whether material flow is normal or not while running the rotary airlock Timely treatment if accumulation.
Daily Maintenance and Repair for Rotary airlock
1. Lubrication
While installation of reducer for rotary airlock driving, the added lubricant should be fully unloaded one month later and add the new lubricant. Regular check for oil level keep. Lubrication for rotary airlock bearings can be done when equipment maintenance.
2. Lutation
Both ends of the viewing window of rotary airlock are U type rubber sealing rings, and they should be replaced immediately if damaged.
Oil seal is for the lutation of impeller shaft and end cover, which should be always checked. It should be replaced immediately if damage, otherwise the material will enter into the rolling bearing and thus cause bearing damage. Users are advised to choose rotary airlock with double oil seal and discharge opening.
Lutation between impeller and air lock shell is the key point of rotary airlock . If the other place does not leak but material accumulation happens, it is mostly because of the abrasion between the impeller outer diameter and the inside holes of the device shell. In this caseusers shouldreplace immediately.
3. Teardown and Maintenance
Correct methods for rotary airlock teardown
1. Tear down by bolt;
2. Tear down by hammer. Remember to put copper bar or wood blocks on spindle head or end cover when teardown.
When replacing, first clean the end cover, then fit the machine with the same specifications of the oil seal and bearing. There must be full lubricating oil.
