purpose

The ZG type hub type grid cleaning machine, abbreviated as hub type grid, is suitable for industrial and domestic wastewater treatment projects, intercepting floating debris and sediment in water. It integrates four functions: interception, slag removal, spiral lifting, and press dewatering. It is currently the most advanced and efficient grid cleaning machine in China, especially suitable for fecal treatment projects in environmental sanitation or slaughterhouses.

Structural characteristics

The cylindrical structure increases the water flow rate of the grille compared to traditional grilles, reduces head loss, reduces the accumulation plane in front of the grille, and ensures more uniform force distribution on the grille;

2. Install a flushing device or an insertable rotating rake structure, and the hub type grille has self-cleaning ability and will never clog;

3 sets of multifunctional functions including sewage interception, transportation, and pressing, with a solid content rate of up to 40%, saving floor space and reducing the cost of subsequent waste treatment;

Made of all stainless steel, running at a slow speed (~5m/min), with a very low failure rate and almost no need for maintenance;

Working principle

The equipment is installed in the water channel at a 35 degree angle to the horizontal plane. Sewage flows into the drum from the end of the hub, and water flows out from the gap of the grid. The grid intercepts floating debris and sediment. As the interception volume increases, the filtering area gradually decreases, and the head loss gradually increases. When the water level difference inside and outside the hub reaches the set value, the cleaning rake automatically rotates to comb out the slag and discharge it into the slag collection hopper inside the drum. It is lifted by the built-in screw conveyor, and the slag is drained while going up. It is then pressed and dehydrated at the top end, and discharged into the slag storage container for external treatment.
