Rainwater grill 1, the rotary rake grate discharge machine of trash rack in the middle position tooth harrow drag chain (other mechanical grille under the traction chain), change the tooth rake movement in the process of clearing fishing direction (as opposed to other grid), to avoid the hard object into the bottom of the teeth 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 surface damage to the equipment; 3, the grid revolving chain equipped with a plurality of tooth harrow decontamination so high decontamination efficiency, clean up thoroughly; 4, compact structure, electrical control simple and easy to automate. [Stainless steel anti-fishing rainwater grill grate discharge machine] structure and working principle: GSHP type rotary rake grate discharge machine is mainly composed of driving device, rack, spindle, gridlines, care scum board, tooth harrow and traction chains. Motor driven through the gear reducer, drive sprocket and chain movement, is fixed to the rotary harrow tooth chain decontamination chain in motion after a gate in the end section, after the guide wheel flipped to the positive side of the front gate position, further movement Uplink inserted and fixed trash rack space, the front gate to intercept dirt lifting out of the water, and with the chain of movement to the slag mouth automatically flip, bucket conveyors or slag dump dirt into the grid after the complete the decontamination process, the liquid through the trash rack gate gap flows, the entire state of a continuous cycle work. For a distributor to control conventional manual control. Electronic control with PLC interface can; linkage with other devices; can be time-controlled; when the liquid level can be controlled, such as in periods of downtime accidents grille clogged water level reached the front gate set the high-water accidents, decontamination machine can Now start the cycle without restrictions; when the level difference can be controlled, such as in periods of downtime accidents grille clogged that the water level difference up to the high water mark set in an accident before the gate, decontamination machine can be switched on immediately. User needs should specify when ordering. For details, see: www.njxulan.com/xlhb0000-Products-10414413
