1、 Performance Description

1) The vertical mixer of the flocculation tank is specially designed and manufactured for the continuous mixing process of the water plant mixing tank, which can generate a uniform fluid motion pattern from top to bottom in the mixing tank.

2）The equipment provided is a vertical mechanical mixer, the electric motor is installed horizontally, the reduction device is gear reduction, and the propeller blades are high-efficiency axial flow blades.

3）The mixer is an outdoor type, with the machine base installed on the top of the mixing tank. The impeller adopts a suspended design, and all components inside the tank, such as the impeller and shaft, are removed, installed, and adjusted from the top of the installation hole under water flow operating conditions.

4）The fault free operating time of the equipment under rated load conditions shall not be less than2Ten thousand hours, service life10Years or more.

5）The whole machine can be installed and disassembled in sections, and is designed with a structure that is easy to disassemble and assemble in sections. However, the motor and reduction device are assembled as a complete set and do not have underwater auxiliary bearings. The maximum size of equipment components can meet the working and installation conditions of the mixing zone in the mixing pool.

6）The equipment operates smoothly and without vibration at the operating speed, and meets the general technical specifications.

7）The position of the impeller in the mixing tank avoids the impact of the inlet and outlet water flow and can form a good up and down circulation of the water body. The impeller speed can be manually adjusted through a frequency converter inside the control box.

8）The components have sufficient strength and rigidity, and all materials used to manufacture the mixer can withstand the corrosion and erosion of flocculants and mixed liquids. All materials in contact with liquids shall be made of corrosion-resistant and non-toxic materials.

9）Electrical Technical Description of Electric Control Box

Each mixer is equipped with an electrical control box, which contains circuit breakers, contactors, motor protectors, surge protectors, etc.

The electric control box is in the form of a box, with a stainless steel shell material and a protection levelIP55And accompanied by1.2High height stainless steel installation bracket.

The electrical control box can meet the following technical specifications:

（1）Each electrical control box generally has one power supply380/220V(Three phase five wire) low-voltage power supply.

（2）The control power required inside the electric control box is supplied by Nantong Huaxin, and the control power is AC220V.

（3）The breaking capacity of electrical equipment inside the box shall not be less than30kAThe breaking capacity of a miniature circuit breaker shall not be less than15kA）

（4）The protection level of indoor electrical control box shall not be less thanIP42The protection level of outdoor electrical control box shall not be less thanIP55.

（5）The electrical control box is equipped with a main incoming circuit breaker on the power supply side, which has short-circuit and overload protection and isolation function.

（6）The electric control box has short-circuit, overload, phase failure, and temperature rise protection, and also has dedicated (such as leakage, overheating, etc.) protection functions for underwater equipment (such as pumps, mixers, etc.).

The electrical control box is equipped with start and stop buttons, automatic, stop, and manual switch, emergency stop button, and start, stop, fault, and power signal indicator lights.

（7）The electrical control box provides passive contact control signals: start/stop, manual/automatic signals, fault and acceptancePLCInterface terminals for control commands.

（8）The supplier of the electrical control box, which is equipped with process equipment, shall provide installation brackets and a complete set of installation accessories for the electrical control box according to the on-site installation location and conditions, and cooperate with the civil engineering installation unit to make installation reservations and embeddings during construction

·Outdoor electrical control box:

（1）The outdoor electrical control box is weather resistant and suitable for continuous operation in corrosive outdoor environments. There is sufficient space inside the box for cable entry and exit, and fixed facilities and fillers are attached. All circuit breakers, starters, isolation devices, etc. are installed on the base plate, connected by busbars, and undergo front maintenance. The box is made of stainless steel and the color of the box isRAL7035Light gray. satisfyIECStandard requirements. Protection level55.

（2）The rotating board is equipped with manual control buttons, conversion switches, and indicator lights. The box is equipped with the required electrical components (such as circuit breakers, starters, protective equipment), cable entry and exit lines, and grounding terminals. There are knock off holes for incoming and outgoing cables at the bottom of the box. The supplier shall submit location maps of all threading holes that are connected to the civil engineering. Each outdoor electrical control box is equipped with mounting brackets, pallets, and accessories suitable for the operating height.

·Technical description of components inside the electrical control box:

All low-voltage electrical components inside the control box comply with the current Chinese national standards（GB）Or the current standards of the International Electrotechnical Commission（IEC）. All low-voltage electrical components, including circuit breakers, contactors, control relays, transfer switches, button indicator lights, etc., have interchangeable models, specifications, and installation methods in China.

·Other

The technical specification data sheet for each complete set of electrical control boxes is the minimum technical requirement for the box. The supplier of the box is responsible for providing the necessary control and protection functions to meet the normal and safe operation of the process equipment. The lack of control and protection functions in the box cannot cause the process equipment to malfunction or be damaged.

The complete set of electrical control boxes meets the anti-corrosion requirements of various production environments in the water plant.

The description of the electrical control box can be found in the technical specification data sheet of the electrical equipment.
