Abstract

The utility model relates to a rotary sewage purification plant which comprises a head section 5, a main body 6, a speed reducer 1, a chain barrier 8, a driving shaft 2, a guiding track 7, a decontamination brush 4, a guiding shaft 3, a water pump 19 and a control device. The device is installed in intake chamber whose width is equal to the width of the device. After the power supply is switched on, the speed reducer 1 drives chain barrier 8 to rotate. The water flow through the barrier gaps, and the filth is blocked and discharged out of the device by the self weight of the filth and the washing. When the water head of the front and back of the main body 6 changes, the control device adjusts the rotary speed of the chain barrier 8 in order to lead the chain barrier 8 to be an optimum regime. If abnormal phenomena appears, the rotary sewage purification plant can automatically cut off the power supply and simultaneously alarm. The utility model is mainly used for the first screening of municipal sewage treatments.

Description

Rotary sewage purification plant

The utility model relates to a kind of row feedwater and gives treatment facility, is the machinery of dirt in the water inlet interception water such as a kind of water treatment field.

China adopts the rake formula conservancy trash machine of machine driving (chain drive, rope drive, hydraulic drive) more at present, and its operating principle is to move up and down along grid by rake teeth, wipes sewage off by being intercepted at the dirt on the grid.But this equipment is at work, if dirt is too much or volume is big or when hard (as wooden unit, duroplasts etc.) rake teeth just be not easy to enter the grid gap, influence scrubbing.In addition in the scrubbing process because rake teeth and grid relative motion, when meeting obstructions, the rake teeth generation causes the vexed machine of clamping stagnation, even burns motor perpendicular to the component of grid.Also very inconvenient when repair apparatus, the maintainer must arrive place under repair under water.
