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