What is a mixing tank

Characteristics of the mixing tank

Diverse structures and configurations

The mixing tank can be made of carbon steel, stainless steel, and other materials according to the requirements of the production process, and heating and cooling devices can be set to meet different processes and production needs. The heating forms include jacket electric heating, coil heating, etc. These designs enable the mixing tank to adapt to various complex production environments.

Efficient mixing performance

The mixing tank uses the rotation of the agitator to shear, stir, and mix different materials, thereby achieving uniform mixing. The speed, shape of the agitator, and the properties of the material will affect the mixing effect. Accessories such as baffles and guide tubes in the mixing tank can further improve the mixing efficiency and ensure the uniformity of material mixing.

Flexible control system

The mixing tank can realize feed control, discharge control, stirring control, and other manual and automatic controls during the mixing process. These control systems make the operation of the mixing tank more flexible and convenient and can meet the needs of different production processes.

Reliable sealing performance

The shaft seal device of the mixing tank is an important part of the mixing equipment. Its function is to ensure that the mixing equipment is in a certain positive pressure or vacuum state to prevent the escape of the stirred material and the infiltration of impurities. As a commonly used shaft seal, the mechanical seal has the advantages of reliable sealing, long service life, low friction power consumption, etc., and can meet the sealing requirements under various complex working conditions.

Humanized design and operation

The design structure and configuration of the mixing tank can be standardized and humanized, making the operation easier. At the same time, the cleaning and maintenance of the mixing tank are relatively convenient, which can reduce production costs and improve production efficiency.

The structure of the tanque de mistura

The mixing tank with an agitator is mainly composed of a tank body, agitator, transmission device, sealing device, heating or cooling device, inlet and outlet, etc.

Tank body

The tank body is the main part of the mixing tank, usually made of stainless steel, carbon steel, and other materials. The shape of the tank body is cylindrical, conical, elliptical, etc., which is selected according to different process requirements. The volume of the tank body also varies, ranging from a few liters to tens of cubic meters. The inner wall of the tank body is usually polished to ensure the cleanliness of the material and prevent the material from adhering.

Agitator

The agitator is the core component of the mixing tank, and its function is to fully mix and stir the material in the tank body. There are many types of agitators, the common ones are paddle agitators, turbine agitators, anchor agitators, ribbon agitators, etc. Different types of agitators are suitable for different materials and process requirements.

  1. Paddle agitator: The paddle agitator is simple-structured and highly versatile. It consists of two or more blades, which are usually flat and mounted on the agitator shaft. The stirring speed of the paddle agitator is low, and it is suitable for mixing and stirring materials with low viscosity.
  2. Turbine agitator: The turbine agitator is a high-speed agitator composed of multiple blades, and the shape of the blades is similar to that of a turbine. The stirring speed of the turbine agitator is fast and the shear force is strong, which is suitable for mixing and stirring materials with high viscosity.
  3. Anchor agitator: The anchor agitator is a stirrer with a shape similar to that of an anchor. It has a large stirring area and is suitable for stirring materials with high viscosity and easy to adhere to the tank wall. The stirring speed of the anchor agitator is low and is usually used in conjunction with other types of agitators.
  4. Ribbon agitator: The ribbon agitator is a stirrer composed of spiral blades. It has a wide stirring range and is suitable for mixing and stirring materials with high viscosity. The stirring speed of the ribbon agitator is low and is usually used in conjunction with other types of agitators.

Transmission device

The transmission device is a component that transmits power to the agitator, and is usually composed of a motor, a reducer, a coupling, etc. The motor is the power source of the mixing tank. Motors of different powers are selected according to the size of the mixing tank and the process requirements. The function of the reducer is to reduce the speed of the motor and increase the torque of the agitator. The function of the coupling is to connect the motor and the reducer to transmit power.

Sealing device

The sealing device is a component that prevents material leakage and external impurities from entering the mixing tank, usually composed of mechanical seals, packing seals, etc. Mechanical seals are sealing devices with good sealing performance and long service life, suitable for occasions with high sealing requirements. Packing seals are sealing devices with simple structures and low cost, suitable for occasions with low sealing requirements.

Heating or cooling device

The heating or cooling device is a component used to control the temperature of the material in the mixing tank, usually composed of a jacket, coils, etc. The jacket is a sleeve installed on the outside of the tank body, which heats or cools the material in the tank body by passing steam, hot water, or cold water. The coil is a spiral pipe installed in the tank body, which heats or cools the material in the tank body by passing steam, hot water, or cold water.

Inlet and outlet

The inlet and outlet are components used for materials to enter and exit the mixing tank, usually composed of valves, pipes, etc. The location and quantity of the inlet and outlet ports are designed according to the process requirements to facilitate the entry and exit of materials and operation.
