I. Introduction: GSHP series rotary mechanical grille (grille decontamination) is a continuous automatic purge fluid debris of various shapes to solid-liquid separation device for the purpose, it can be used as a dedicated device widely used in urban sewage treatment, water industry, power plant intakes, as well as textiles, food processing, paper, leather and other industries essential to the production process and special equipment, is currently China's most advanced solid-liquid separation equipment, Also known as rotary mechanical grille grille decontamination. Second, use: GSHP type rotary rake screen machine for urban sewage treatment plants, water plants, pumping stations and other rainwater into drains, water floats * to ensure the normal operation of the pump and the subsequent process. Three, GSHP type rotary rake screen machine Features: 1, due to the placement of trash rack in the middle position decontamination machine drag chain harrow teeth in (other mechanical traction chain under the grill), changing the tooth harrow fishing in the clear direction of movement of the process (as opposed to other grid), to avoid the hard object into the bottom of the tooth rake and drag chain stuck; 2, on the gear output shaft sprocket disk overload protection device installed in order to avoid overloading the causes of accidents and damage to equipment; 3, the grill is equipped with a revolving chain multiple decontamination tooth harrow, making high decontamination efficiency, clean up thoroughly. Four, GSHP rotary rake grid structure and working principle: decontamination machine is mainly driven by the transmission, chassis, spindle, trash rack, care slag board, tooth harrow and traction chains. Motor driven by post-gear reducer, drive sprocket and chain movement, fixed to the rotary harrow tooth chain chain decontamination after gate movement in the end the Ministry, after the guide wheel flipped to the front gate welcoming the position to continue campaign Uplink insert gridlines fixed gap, the gate lifting belt before * the dirt out of the water, and with the movement of the chain to the slag mouth automatically flip, conveyors or slag dump buckets of dirt to the grid after the complete the decontamination process, the liquid through the trash rack gate gap flows, the entire state of a continuous cycle of work. Five, six shape installation process, the main technical parameters
