The control part of the electric heating mixing tank mainly includes the mixing control system, weighing control system, temperature control system, liquid level control system, etc.
1、 The mixing system is divided into upper mixing and lower mixing according to the installation position. Upper stirring is often mechanical stirring, while lower stirring is often magnetic stirring.
1. Mechanical mixing: The mixing motor is installed on the top of the tank, and the mixing shaft consists of an upper half shaft and a lower half shaft. The 204 type hard alloy mechanical seal with good sealing performance and long service life is used between the upper half shaft and the tank body. The lower half shaft is connected to the upper half shaft through a flange, and the mixing blade is welded to the lower mixing shaft.
2. There are two types of speed control: manual mechanical speed regulation and variable frequency speed regulation. Mechanical speed regulation is achieved by rotating the speed control handwheel of the gearbox; Variable frequency speed regulation achieves speed regulation by changing the power frequency; Please refer to the 'Speed Control Manual' for details. Or a fixed rotational speed.
3. Magnetic stirring: The driving motor is installed at the bottom of the tank, and the motor shaft is directly connected to the inner magnetic steel. The outer magnetic steel is integrated with the stirring blade, and the inner and outer magnetic steel are sleevedcompletelyIsolation, no direct contact. When the motor rotates, the inner magnetic steel drives the outer magnetic steel to rotate through magnetic effect, thereby achieving the mixing effect.
2、 The weighing control system is installed under the gasket of the tank bottom bracket, with an integrated design that saves equipment installation space.Adopting stainless steel welded sealed sensors, with a protection level of IP68, it can be used in various harsh environments and accurately weigh the weight of materials in the electric heating mixing tank.
3、 Thermometers can be installed with bimetallic thermometers or PT100 thermometers according to customer needs: Bimetallic thermometers are composed of bimetallic sheets wound in a circular curved shape. When one end expands due to heat, it drives the pointer to rotate, and the working instrument displays the corresponding temperature value, which is convenient and fast.
4、 The glass tube level gauge is a stainless steel protective tube type with a glass tube jacket. The two ends of the tube are connected to the tank to form a connector. The liquid level height of the material in the electric heating distribution tank can be read by the liquid level height in the glass tube. The highest andminimumThere is a needle valve installed at the end. When the temperature or pressure inside the equipment is too high and may exceed the capacity of the glass tube, the needle valve can be temporarily closed to protect the glass tube.
