Clear classes in water treatment usually include concrete, precipitation and filtration. The treatment objects are m--nly suspension and colloid impurities in water. After the raw water is added, the suspension of the water and the colloid in the water form a large particle flocculation, and then the gravity is separated by the sedimentation tank. The mechanical response sedimentation tank is a water purification structure with two functions: concrete and flocculation. This model is an experimental device that displays the internal structure of the flocculation reaction tank and the inclined sedimentation tank. Hope to achieve the following purpose:

1. Directly observe the organic glass device to deepen the understanding of each part of the composition;

2. Grasp the direction of water flow and operation and use of mechanical reaction tanks and sedimentation pools, and observe the condition of flocculation and precipitation.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Fundamental water volume: 0.84L/H

3. Social condensation time: 10min

4. The speed of stirring slurry line is 0.2 ～ 0.5m/s (adjustable),

5. Total size of the device: length × width × height = 1170mm × 300mm × 600mm

6. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 500W power, safety protection: ground protection, leakage protection, overcurrent protection

1. Equipment overview

 

The PLC programming controller is a new type of industrial control device developed based on the foundation of a microblog machine. With the characteristics of small size, strong function, high reliability, and convenient application installation, it quickly occupies a dominant position in my country's industrial control and continuously develops. According to this development situation, the major college branches of the country and various vocational and technical schools of the country have incorporated PLC teaching into teaching tasks as a compulsory course for electronics, electrical and industrial automation. The PLC programming experiment system is a new generation of PLC teaching products developed based on this teaching requirements. Since its launch, it has received unanimous pr--se from teaching teachers and experts in major colleges. The full set of devices are reasonable, powerful, simple and convenient to operate, and have great help for students' understanding and mastering the control principles and methods of programming controllers, and accelerating the programming method of learning PLC. It is an ideal tool for PLC teaching.
