Floating type of gravity water decanter

Also called float type water decanter, simple structure, is mainly composed of buoy, decantation hoses, hose, connectors, and support. Working principle based on gravity, buoyancy and fluid pressure, thus the performance is very stable, no operation and maintenance, no power consumption; And general float type water decanter like revolving water decanter, telescopic water decanter, needed a spring elasticity, mechanical strength, power, control components and seal friction, complicated structure, not only energy consumption, life-long maintenance, there is likely to lead to incorrect operation, mechanical failure, control components failure, etc. All kinds of trouble.

The composition of water decanter is commonly: collect water device, connection device and transmission device. Closed water device is equipped with damper, into the sink and float, and so on, its role is to handle good that collected supernatant fluid water decanter, again through the catheter. Due to decant moment when water flow is larger, in water decant should make water pass already, and to make the reactor of the settling sludge from disturbance, more cannot make sludge with the water out, therefore the design of the closed water device is very important, especially in siphon scoop water decanter is particularly important.

Water decanter of connection is another key component of the water decanter. Need to constantly turn in the drainage water decanter, and its connection device to ensure the running free, both at the same time to ensure that the closure. Water decanter of transmission device is the key to guarantee the normal work of the water decanter, whether use hydraulic or mechanical transmission, all need with the organic combination of automatic control system, through the automatic program control decantation water movement.

Push-rod revolving water decanter is in our factory in the digestion of foreign technology developed on the basis of, specially designed for sequencing batch type biological treatment systems, they have performance of hydraulic machinery. Can realize the decantation during the process of water into the water weir flow in laminar flow state, decant the water depth is adjustable, make the water yield is adjustable, is the key to the circulation process of activated sludge system equipment. PS - III push-rod revolving water decanter schedule precision adjustable, decantation water with good results, reliable and low energy consumption, no noise, high automation degree, easy centralized management, small volume, low failure rate, convenient maintenance. Can be widely used in municipal sewage treatment plant and paper making, beer, tanning, pharmacy, food, garbage disposal industry such as sewage treatment.

The main technological process is as follows:

SBR and CASS pool water, blower aeration, sludge precipitation, water decanter decantation

operating principle

Push-rod revolving water decanter by decantation water device, transmission device, skimming buoy device and rotary bearing, etc. Driving mechanism through scalable push rod drives the decantation water device and skimming buoy device around the rotary bearing rotation, thus make the decantation water weir crest moved up and down, to decant out that the purpose of supernatant fluid. PS type revolving water decanter is in our factory in the digestion of foreign technology developed on the basis of, designed specifically for sequencing batch type biological treatment system, has the good performance of hydraulic machinery. Can realize the decantation during the process of water into the water weir flow in laminar flow state, decant the whole process of water USES to run at a constant speed, smooth surface without fluctuation, is the key to the circulation process of activated sludge system equipment. The water decanter decantation water depth can be adjusted freely, the user can be adjusted according to the actual needs of water yield, it has the decantation water effect is good, reliable, high degree of automation and centralized management convenient, low failure rate, convenient maintenance. Can be widely used in municipal sewage treatment plant and paper making

Rotating type decanter

By decantation weir crest, branch pipe, water mains, can be 360 ° rotation of rotary support, sliding support, driving device, automatic control device, etc. Under the action of driving devices at work, decant the water weir crest with the center line of the rotary support at the bottom of the decanter for axial abject in circular motion transmission, in the process of the SBR reaction in the pool that the supernatant fluid by decantation water weir crest to decant water pipe, then through decantation water mains. Decant water after completion of work, decant the water weir crest for shaft upward with the center line of the rotary support at the bottom of the water decanter, uniform circular motion, make the decantation water weir crest parked at the standby location, treated water, biochemical reaction, such as precipitation process completed before the next decantation water process. Water decanter is batch Activated Sludge Process (Seguencing Beacter Activated Sludge Process for SBR) sewage will match mechanism. Batch activated sludge process of sewage disposal mechanism is the same as the common activated sludge process, the difference between the original wastewater instead of progressive flows through each processing unit discharge to the list

Equipment main technical performance

1, equipment adopt the rotational support at three parts with compact, smooth operation. 2, buoy floating design, can according to the pool water level changing and always keep buoy slag surface and water flat, to achieve the desired effect of the slag.

3, equipment power cycloidal reducer drive screw for uniform motion in a straight line, can guarantee the decantation during operation continuously and evenly decantation water sink.

4, equipment runtime decantation uniform speed, water decant no sludge retention in the sink, smooth surface no fluctuations, the main body power noise, decantation water automatically kickback.

5, underwater rotating part adopts mechanical seal device, can guarantee the water decanter rotating part of the long-term operation without leaking.

6, mechanical transmission part adopts cycloidal reducer, effectively stabilize the speed of water decant and provide
