Product Description

SBR Waste water treatment system Revolving type decanter/liquid decanter/industrial decanter


Decanter Equipment introduction:
The water is CASS method, SBR method, ICEAS methods, such as the sewage treatment process is the most commonly used in the key equipment. In beer, food, beverage, pharmaceutical and other industries of wastewater and the urban sewage treatment, by CASS method of the process has been mainly to a wide range of applications. The equipment has Bi water effect is good, low energy consumption, without noise, a high degree of automation, facilitates concentration control, convenient maintenance.


Decanter Main structure and working principle

Decanter is componented by the drive mechanism, lifting nuts, decanter weir tank, slag floats, support tube, snorkel, water main pipe, water rotary sliding bearing,control Systems and other.
1,Main structure
(1) Drive mechanism using hoist. Drive mechanism pulled up and down through the hoist driven decanter device and skimming device floats around slewing rotation, so that decanter weir move up and down.
Siemens inverter drive motor control, can realize stepless speed regulation function. Decanter Decanter sink down, press down the speed of the design, decanter to the lowest point, improved rapidly returned. The rate of decline according to pool area. Decanter end position from the rest position to return to a time not more than 10min. Decanter weir trough start off smoothly, the weir under the surface does not affect the drainage balanced agitation.
Drive mechanism can be on the water decanter water decant schedule for precise positioning, and with a torque protection device, in the event of an accident, to protect gear from harm.
(2) Decanter tank is key parts of the decant work. Provided to prevent scum decanted water tank, a water tank in the front and rear sides decanter has scum baffle, and a curved front side of the baffle design to reduce the decanter tank decreases the impact on the water, agitation, to ensure Decanter precipitated sludge is not agitated, decanter whole with sufficient strength and rigidity.
Weir plate is equipped with the horizontal adjusting mechanism, the levelness of the weir plate is not greater than 2 mm after installation.
(3) Support tube made of stainless steel pipe, pipe from decanter tank and the other end is connected by a flange head with main pipe. On the one hand the decanter into the supernatant was decanted into the water in the tank head, sink with water decanter hand turn even as the overall supervisor, head of the decanter tank around the center of rotation of the water.
On the support tube, respectively with a set of lugs, becoming the decanter tank lifting points of rise and fall , the set of point position and the designs of the connecting rod length are determined through rigorous calculation, must be able to ensure uniform decanter sink down to decrease in order to ensure uniform decanter.
(4) The main pipe made of Steel pipe , closed at one end, provided on the support shaft and the other end fixed to the outlet pipe coil packing, the supernatant was decanted out of the leads outside the pool.
Tube located four branch pipes, branch pipes connected with the support tube using the flange.
(5) Underwater slide bearing slewing bearing copper intercropping, rotating flexible, easy accessibility, and is equipped with water lubrication device. Pipe shaft, axial able to withstand some pressure.
(6) Drive system fully sealed, compact, help protect the drive mechanism.
2,Working principle
Decanter generally stopped at the highest water level of the upper pool.
Decanter time set in the PLC, through hoist putter down the decanter weir surface, then level switches provide signals to start VVVF decanter, Under the effect of buoyancy, the buoy slag equipment away scum and blocked it,, the supernatant was decanted into the weir trough began turning drain water discharged through the levels outside the pool, pool deck steady decline until the decanter to the set level (time) to stop, the hoist automatically switches to power-frequency form, putting the weir tank back to the initial position to meet the ever-changing water levels and can automatically carry out periodic draining process requirements
