Mechanical stirring flocculation tower experimental device

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

*r source heat pump thermal machine tr--ning assessment device is a product developed in accordance with the requirements of the Ministry of Education's "Revitalizing the 21st Century Vocational Education Course Reform and Teaching Material Construction Plan", and develops in accordance with the requirements of vocational education teaching and tr--ning requirements. Suitable for high vocational colleges and vocational schools, cooling and heat -making technology, heat pump technology teaching tr--ning experimental tr--ning devices. The heat pump technology is one of the effective measures for recycling and using low -level thermal energy. Studying and promotion of heat pump technology is of great significance to energy conservation. ** The development of refrigeration technology in recent years, heat pump technology has been increasingly widely used in my country.

1. Device characteristics

1. The system crew is equipped with multiple protection systems such as high and low pressure protection systems, overload protection, lack of phase protection, and frosting functions to ensure the safety, reliable and stable operation of the system, and does not affect teaching courses.

2. The whole machine system is controlled by fully automatic and intelligent control. It is convenient to operate. Water temperature, water level, opening, control, and time can be freely set by the user. The whole machine uses the power -off automatic memory function.

3. This experimental device uses compressor, high -quality copper forging heat exchangers, high heat exchange efficiency, safe and reliable. The water tank adopts advanced silver technology, combining fashion with ** technology. The appearance of the equipment is beautiful and generous. The inner water tank is made of 304 st--nless steel. It is durable and is not easy to corrode and damage.

4. The system adopts industrial --r source heat pump thermal water units, which is consistent with actual industrial equipment, allowing teaching to be in line with actual applications. Outdoor hosts adopt a thick sheet metal p--nt type, with different experimental environments, and long -term effective work without rust and corrosion.

5. The entire tr--ning device integrates the --r source heat pump thermal machine system, electrical control system, and fault simulation system. The process system is truly complete, the structure is clear and compact, which fully meets the students' requirements for tr--ning.

6. The tr--ning device visually shows the system structure and working principle of the thermal pump -type water heater. It can be clearly seen that the structure of the heating circulation system and the m--n components can be clearly seen. The table, the real -time working state of the entire heat pump system is clear at a glance.
