Rotary grille equipment

Rotary grille equipment: also known as rotatable grille cleaning machine. It can continuously and automatically intercept and remove various large solid impurities in sewage. Used for pre pump decontamination in urban sewage stations and sewage treatment plants. The rotary grille has a compact structure, smooth operation, easy operation, and automatic unloading, making it an ideal and necessary pre pump cleaning equipment.

　　Rotary grille equipmentIntroduction

Rotary grille, also known as rotatable grille cleaning machine. It can continuously and automatically intercept and remove various large solid impurities in sewage. Used for pre pump decontamination in urban sewage stations and sewage treatment plants. The rotary grille has a compact structure, smooth operation, easy operation, and automatic unloading, making it an ideal and necessary pre pump cleaning equipment.

　　Rotary grille equipmentworking principle

The rotary grille rotates continuously, and the rake teeth intercept solid suspended solids in the sewage. When the intercepted solids are transported to the upper part of the equipment, the rake teeth change their direction of movement, and solid debris falls down on its own. The debris stuck to the rake teeth is cleaned up by the rubber brush of the cleaning mechanism running in the opposite direction. When overloaded, the spring presses down and the proximity plate approaches the proximity switch, causing the motor to stop running.

structural characteristics

The rotary grille mainly consists of a driving device, frame, sprocket, chain, rake teeth, cleaning device, and elastic overload protection device.

installation and debugging

1. The lifting of the rotary grille machine must be carried out by hanging the top plate hole or lower foot lifting ring of the box with steel wire rope.

2. Installation position: The bottom foot of the rotary grille must be flush with the bottom surface, and the front end of the equipment should be basically flush with the front end face of the groove.

3. Pour cement mortar into the anchor bolts, wait for the cement to solidify, and then tighten the nuts.

4. Before starting up, the front of the rotary grille should be free of large stones or other coarse debris. If there are any, they should be removed before starting up.

5. Operation

1) Before operation, check if all components are loose.

2) Remove the motor cover and rotate the fan by hand. The entire machine should run smoothly and flexibly.

3) Lubricate the sprocket and chain with lubricating oil.

4) Jogging the motor, visually check if the direction of operation is correct, start the motor, check if the electrical action is normal and reliable, and if the working current is normal.

5) During operation, all components should rotate flexibly without any jamming or abnormal sounds.

6) The rotary grille uses elastic devices as overload protection. Adjust the proximity position of the switch before use.

maintenance

1. The bearings of this machine are lubricated with calcium based grease, which has been fully added during installation. If running continuously, open the bearing gland and add sufficient lubricating grease every six months.

2. Chain lubrication: Lubricate the chain and sprocket once a week with lubricating oil.

3. The lubricating oil of the cycloidal pinwheel reducer should be kept at the normal position of the oil gauge.

4. Replace the lubricating oil for the motor bearings every six months.
