Brief Instruction of flour mill airlock feeder
Flour mill airlock feeder is an important device for pneumatic conveying and dust removal. The main usage of flour mill airlock feeder 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. Flour mill airlock feeder can handle materials in powder, pellet, flake shapes and also fiber materials. And at the same time, flour mill airlock feeder 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 flour mill airlock feeder
This flour mill airlock feeder is a kind of improved impeller open type flour mill airlock feeder. It is a discharging machine structured with impeller, bearing, oil seal, airlock shell, end cover and other spare parts. On the top of the flour mill airlock feeder there is flange connected with the unload opening of discharger to receive the material from discharger, and then unload material from the bottom of flour mill airlock feeder while impeller rotating. The impeller is open type, which can prevent material from blocking as well as reduce flour mill airlock feeder weight and shape.
Model Selection for flour mill airlock feeder and Using Form
Model selection basis for flour mill airlock feeder:
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 airlock of flour mill if above 60°C);
5. Material handling capacity(Theoretical calculation of volume×1.2).
Using form for flour mill airlock feeder:
Independent work by single flour mill airlock feeder( transmission by belt, chain or direct coupling), multi-machine series and in parallel. No more than 5 flour mill airlocks feeder 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 flour mill airlock feeder
Before installation flour mill airlock feeder must be carefully examined to make sure the impeller rotates flexibly and that relevant connecting parts reliable and correct. Then fix the flour mill airlock feeder 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 flour mill airlock feeder is used, there must be overload and short-circuit protection devices in order to prevent the damage of motor.
Before feeding, flour mill airlock feeder with separate power must be turned on before host machine, while flour mill airlock feeder without separate power should be turned on with host machine at the same time. And flour mill airlock feeder 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 flour mill airlock feeder. Timely treatment if accumulation.
Daily Maintenance and Repair for flour mill airlock feeder
1. Lubrication
While installation of reducer for flour mill airlock feeder driving, the added lubricant should be fully unloaded one month later and add the new lubricant. Regular check for oil level keep. Lubrication for flour mill airlock feeder bearings can be done when equipment maintenance.
2. Lutation
Both ends of the viewing window of flour mill airlocks feeder 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 flour mill airlock feeder with double oil seal and discharge opening.
Lutation between impeller and air lock shell is the key point of flour mill airlock feeder. 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 flour mill airlock feeder 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.
