The Mechanical Screen is composed of driven device, rake tooth facility, flush facility, which is assembled by a special rake tooth into a group of rotary grille chain.
Under the drive of motor reducer, the rake tooth chain turn Rotary motion as reverse flow. When it get the top, the guiding power of the Geneva wheel and curve will make every rake tooth to do the relative self-cleaning motion, then due to the gravity, most of the solid will drop down. The sundries sticking in the rake tooth will be cleaned up by sweeper's reverse movement.
Structure and Working Principle
Toothed harrow made of nylon or stainless steel is equipped to the chain shaft according to certain rankings, which will form an enclosed circulating toothed harrow surface. The whole toothed harrow surface does the circulating exercise from top to bottom driven by the driven chain. The solid suspended matter intercepted on the toothed harrow will be picked up to the platform, and cleaned by turning the brush. Then the goal of protecting the water pump and reducing subsequent work load will be reached.
1. Sieve screen is offered with apertures from 0.5 mm ,1mm, 1.5mm to 3 mm;
2. Passive filtration method maximizes solids removal;
3. No moving parts, easy to set up with small installation area;
4. Self-cleaning, easy to maintain, and the running cost is zero;
5. No actuating equipment, neither vibration nor noise is produced;
6. Simple structure, operation simplicity, sturdiness;
