QXB4.0potentialWater aeratorstructure

QXB4.0potentialWater centrifugal aeratorIt is a type of environmental protection equipment that is widely used in many situations, especially in sewage treatment plants and some slaughterhouse wastewater treatment plants. Due to the fact that this device is more capable of causing damage to ordinary items than regular equipment, many difficult to treat wastewater treatment plants adopt this environmentally friendly equipment. However, there are currently many models of this product, and new types of submersible aerators are developed and produced every once in a while. Today, we will introduce to you the main structural components of the submersible aerators currently produced by our factory, hoping to be helpful for friends who need to purchase environmentally friendly equipment.

1. Main reduction mechanism: composed of a main variable frequency speed regulating motor, an incremental encoder, and a main reducer. The motor starts and is reduced by the main reducer, increasing the torque. By adjusting the speed of the variable frequency speed control motor with an incremental encoder, various accurate speed outputs can be achieved to meet the process requirements of the aerator. The reducer gears are made of low-carbon high-strength alloy materials and processed through processes such as carburizing, quenching, and grinding. Significantly improve the load-bearing capacity of the gearbox.

2. Lifting mechanism: composed of lifting reducer, absolute value encoder, trapezoidal screw, KK alloy nut, bearing seat, bearing sleeve, connection method, and several bearings. By using a lifting mechanism with an absolute value encoder, more accurate lifting stroke and speed can be achieved.

3. Output mechanism: The output mechanism consists of an internal spline shaft (fixedly connected to the output gear of the main reducer), an external spline shaft (fixedly connected to the output gear of the main reducer), an external spline shaft, a coupling, a transmission shaft, etc. The internal and external spline shafts are treated with high-strength medium carbon alloy quenching and tempering. The axial direction between the internal and external spline shafts is a sliding connection, and the external spline shaft can achieve up and down lifting while transmitting torque.

Due to the diversity of industrial wastewater components, treatment systems composed of several methods often need to meet the prescribed discharge standards. According to the selection of classification methods, sewage treatment can be divided into physical methods, chemical methods, physicochemical methods, and biological methods4 methods. Biological method is a method of utilizing wastewater microorganisms to metabolize and differentiate water to degrade organic matter. Due to its extensive disposal, low investment, characteristics, economy, and reliability, it is the most water-soluble method in the world.

Based on the biological treatment of microorganisms under aerobic conditions, it can be divided into two categories: aerobic and anaerobic. In general, aerobic analogy is applicable to low concentration wastewater, such as ethylene plant wastewaterThe method of anaerobic treatment of sludge and high concentration wastewater. Aerobic biological treatment can be divided into activated sludge method and biofilm method. Activated sludge process is an artificial water augmentation measure, which is a main task for removing organic matter from wastewater based on activated sludge. Aerobic microorganisms in activated sludge must be able to operate in the presence of oxygen. The relationship between aerobic and aerobic capacity growth in the aeration tank of the sewage treatment biochemical system is positive.

The supply of dissolved oxygen should be based on the number of aerobic microorganisms, physiological characteristics, substrate properties, and concentration. In this way, activated sludge can degrade organic matter under optimal degradation conditions. According to the experimental results, the results indicate that the dissolved oxygen in the aeration tank is maintained at3 ~ 4mg/L， If the oxygen supply is insufficient, the performance of activated sludge will be poor, resulting in poor wastewater treatment efficiency. To ensure sufficient oxygen supply, it is necessary to rely on a device such as an aeration device.

Aeration treatment of sewage channels can play a role in treating and purifying sewage. Aeration, as an important process in the aerobic biochemical treatment system for sewage, is used to oxygenate the reactor, ensuring the dissolved oxygen required for microbial biochemical reactions, and maintaining sufficient mixing of microorganisms, substrates, and dissolved oxygen in the reactor, namely mud, water, and gas, providing favorable biochemical reaction conditions for microbial degradation of organic matter. At the same time, aeration is also the most expensive process in the aerobic biochemical treatment system for sewage, and the power consumption of aeration and oxygenation generally accounts for the total power consumption60%～70%Therefore, selecting aeration devices with low energy consumption and low cost is of great significance. Nowadays, with the continuous improvement of process technology, in order to save various costs during the operation of such equipment, solar aerators have been put into use. The use of solar energy can greatly reduce the huge electricity costs incurred due to power functions.
