The use of disc feeder structure installation operation and maintenance

1 Purpose and scope of use
Disc feeder for the volumetric Vibrating feeder, it can even be continuously fed to the next device in the material to go , feed can be adjusted.
Upper portion of the cover , the degree of purification suitable for the air require a higher place .
Type upper no cover , operation and maintenance more convenient and suitable for less demanding place air purification .
Disc feeding functional feed powder, granular or small block of material . For example : coal, cement , clinker, limestone, clay and so on. Not suitable for the feed viscosity,

easy flow or flow particularly good materials.
2 Structure and working principle
The machine consists of : electric motor , deceleration devices , disc , disk sets, scraper , Pan feeder adjusting device and channel steel columns composed of several parts .
It consists of motor through V-belt , worm reducer, vertical shaft, driven by rotation of the disc . The lower disc set with worm gear connected to the upper column through the

channel connected with the silo . Motor through the motor base plate fixed to the side cover . So the entire disc feeder is hanging on

Silo below, but Channel Columns can turn around and become sitting install disc feeder .
Feed material from the hopper through the following screw gate out of the machine into the flow tube and activities on the disc sleeve . Since the rotation of the disc and the

action of the blade to be scraped , put through a discharge port plate , slip into the next device to go.
Adjusting production capacity there are three ways :
( 1 ) regulating blade position: Turn the handwheel screw through both complete. And through that the scraper blade shaft position indicator .
( 2 ) regulate the activities of the sleeve height by turning the handwheel screw complete.
( 3 ) When using the DC motor drive, the motor speed can be changed to adjust .
3 Installation and Commissioning
( 1 ) According to the silo center to find a good location , close to the center deviation of not more than 5 mm .
( 2 ) the disc must be in the horizontal position , the deviation not greater than 0.5/1000 . Channel Columns then fixed on the lower part of the silo , the feed tube with screw

gate connections.
( 3 ) hand plate moving belt, check the operation is flexible.
( 4 ) Check the worm gear lubricant inside height , and to inject the right amount of lubrication points, lubricants ( grease ) .
( 5 ) empty load test load test should be carried out after eight hours , check for anomalies. Also check the adjustment device is a flexible and reliable lag , everything is

normal , before formally put into production.
4 operation, maintenance and overhaul
( 1 ) should be carefully checked before driving scraper position and activities of the sleeve meets the requirements of the volume of feed .
( 2 ) should be carefully checked before driving the lubrication of the various parts of the history and inject the right amount of lubricant ( grease ) .
( 3 ) Subject to the disc while driving smooth rotation , and then open the screw gate . Parking should be closed screw gate and then stop.
( 4 ) Production capacity adjustment method : When using DC drive , try to adjust the speed of the method used . When AC drive , then try to use a method to change the blade

position . Only in the above two methods ( DC drive , in addition to adjust the speed , it can also adjust the blade position ) can not be

Meet the needs , the only regulate the activities of the sleeve height using a method . When adjusting, the material must be taken to the outermost edge of the disc should

maintain a distance S , in order to avoid material stuck disc , causing an overload caused by something mine .
( 5 ) operation should always check lubrication , bearings work , the part of temperature rise , if there is overheating , should be immediately eliminated.
( 6 ) Long-term operation should be regularly checked scraper , activity sleeve , disc , worm gear, belt and seal losses, in order to adjust or replace .
( 7 ) Maintenance and replacement of worn parts deadline , according to the usage of specific decisions .
( 8 ) Replacement parts can be based on the following principles demolition methods :
a. replacement worm gear and worm shaft portion of the radial ball bearings , the first to get rid of the pressure in the center of the disc pads, dish care through the two

screw holes at the top of the disc tray and pull out the disc together , and then remove the pulley cover , remove the belt , you can remove the worm gear overhaul .
b. Replace the lower worm shaft radial ball bearings or thrust bearings may be used without removing the entire worm gear box , as long as the bottom three disc set with screws

to tighten overhaul , until you feel it has so far withstood the disc . The three screws and a good long stay disk spindle after they removable reducer

The bottom of the bearing cap , remove the thrust bearing cap , could be put on the three demolition through the bearing bore of the bearing sleeve silk top out , radial ball

bearings are also together with the bearing sleeve . Replace with new bearings , you must remove the lower part of the plate with a screw cap to withdraw only after a trial .
c. Replace worm or worm bearings at both ends , as long as both ends of the gland opening , you can remove screw hole through the bearing sleeve , remove the cover and bearing

together , the worm will be easily pulled out from the bearing hole came.
( 9 ) When installing worm reducer , gear cover seal groove should be filled with dry yellow oil .
