Chemical grade high viscosity corrosion-resistant mixing and homogenization tank system components:
1、 Slow hybrid system
The mixing blade structure is frame type and double mixing type. The middle blade and the frame type enclosed wall rotating blade are convective mixing. The working speed of the rotating blade should be within the range of 15-60r/min.
Speed too fast: The reducer is damaged and accelerates. The baffle is made of polytetrafluoroethylene and is adjusted to be flush with the pot wall for heat exchange.
Slow speed: The reducer is overheating severely.
Two low-speed mixing systems that rotate in opposite directions. Composed of a hanger covered with scrapers and blades.
The fully automatic movable scraper is made of PTFE material and can only work when there is material available. It is also easy to disassemble and clean.
3 concentric axes for dynamic balance.
The external hanger and internal blades are made of stainless steel SUS316L.
5 electronic timers are installed on the PLC for easy adjustment of working time.
6. Equipped with a reduction motor - produced by ABB company, the speed can be directly adjusted by a frequency converter, with a speed of 0-80rpm/min.
The slow mixing system generates two separate reverse flows inside the material.
(1) A vertical flow along the center forces the material to flow towards the bottom of the container, which serves to quickly feed the material to the bottom of the homogenization turbine.
(2) A circular flow forces the material to surround the inner wall of the mixing container for heat exchange during the heating and cooling stages, and to avoid damage to the material due to overheating or undercooling.
2、 Rapid homogeneous mixing system
The rapid homogenization mixing action is completed by a turbine installed at the center of the tank bottom.
The turbine consists of a toothed stator and a rotor with blades.
The turbine is made of SUS316L stainless steel, and the rotating parts are balanced by concentric shafts.
4 electronic timers are installed on the PLC to adjust the processing time.
5. Equipped with a reduction motor - produced by ABB company, using variable frequency speed regulation, with a speed of 0-3000r/min
The characteristics of this structural form ensure a high degree of cleanliness during the processing, for the following reasons:
Due to the absence of motor flange connections, there will be no pollution to the materials.
The turbine setup is easy to clean, maintain, and load/unload.
The bottom of the tank is smooth and seamless, and easy to clean.
A central valve (option) can be installed for unloading.
The mixing and homogenization motor is installed on the upper part of the tank, away from the processing area.
Strictly protect the safety of operators.
3、 Heating/cooling system
Heat is transferred from the external steam to the inner tank through the jacket
Control the water temperature in the jacket through a temperature controller on the PLC.
The temperature control consists of an electronic temperature controller and a thermocouple installed at the bottom of the tank, which can accurately read the actual temperature of the material.
Cooling is achieved directly through the jacket with external cold water.
4、 Vacuum system
1. Water ring vacuum pump.
The vacuum gauge indicates the vacuum inside the container,
The vacuum safety switch is designed to prevent the operation of opening the upper cover in a vacuum state.
The airtightness of the upper cover is ensured by the silicon packing on the flange.
Theoretically, the vacuum degree is 730mm/Hg at 20 ℃. To achieve the emulsification effect of *, it is necessary to avoid air entering the material. Processing under vacuum allows direct injection of liquid or powder into the container.
5、 Upper cover lifting system
The lifting and lowering of the upper cover is accomplished by a set of hydraulic devices equipped with a safety limit system, which can hold the upper cover in any desired position.
6、 Container dumping system
The container dumping system is used for unloading, which is completed by a manual wheel and stays at any angle.
7、 Processing control
The observation window is equipped with a washer and light, providing good internal visibility.
8、 Security system
1. The safety lock prohibits accidental opening of the upper cover in a vacuum state.
2. The upper cover is not perfectly aligned with the container, and the sealing degree is insufficient. Stop using it.
If the upper cover is not raised, the tilting function will be disabled.
When the upper cover is opened, the mixing and homogenization motors and vacuum pump are stopped.
5. The limit micro switch automatically executes the opening/closing of the upper cover.
6. Each parameter can be adjusted according to user requirements and achieve * performance.
