ZG-II Type Rotary-Drum Grid Trash-Cleaning Machine

ZG-II Type Rotary-Drum Grid Trash-Cleaning Machine

ZG-II type rotary-drum grid trash-cleaning machine is one of the newly developed complete sets of series of products for water supply and drainage pre-treatment in our plant. Referring to the imported equipment, this product is independently designed as a domestic initiative project that passes the appraisal of scientific and technological achievements (No.: 2003EB060572), it is also a provincial high-tech product (No.: 030282G0080N), getting a national patent (No.: ZL 02260164.3). This product is widely used in sewage treatment projects such as urban sewage, industrial wastewater, food processing industry, paper-making industry, etc. This equipment is used for salvaging and removing the floating objects and sediments at the intake of water sources and pressing the screenings to squeeze out the water and then remove them.

This equipment is installed in the water channel, angled at 35° from horizontal, the sewage water flows through the grid bars at the open end of the grid and then into the water channel, solid trash can be retained by the grid bars, the rotary rake positioned on the center axis will rotate within the gate drum when it reaches a certain water level difference, the teeth of rotary rake enter into the grid bars and clean them, meanwhile running up under the action of driving force, when running to the highest point, all screenings fall into the central spiral groove, where there is a screw conveyor and press AiO (all-in-one) machine to press the screenings and squeeze out the water and finally the screenings are delivered to the discharge hopper at the upper end.

• The grid and the water flow form an angel of 35°, much of the trash can be separated even its thickness is less thick than grid gap due to the formation of baffling. 

• A flusher is equipped in the grid, with self-cleaning function. 

• The cylindrical structure makes the grid have an increased water flow compared with the traditional grid, with its decreased head loss, and moreover, the surface of accumulation is decreased in front of the grid. 

• All parts in contact with water are made of stainless steel, and these parts have been processed with pickling and passivating techniques, with strong corrosion resistance and a long service life in all domestic sewage treatment and the majority of industrial water treatment. 

• With the help of the integrated workflow of salvaging, conveying and pressing, the occupied area is decreased and the cost for subsequent refuse disposal can be also cut down. 

• There is almost no need for maintenance, no refueling is needed at the rotation point, and the refueling times required for the driving device is very few.
