特点
实验室型混合机整机装于可移动式的底座上。主要部件包括机架、回转系统、电气控制系统、料斗等。锥形混合料斗主要由斗体、斗盖及卡箍、蝶阀等组成。
料斗采用悬臂固定方式装于回转轴上,可360度旋转的。由于料斗对称的轴线与回转臂回转轴线成一夹角,不同组分物料在密闭的料斗中进行三维空间运动,产生强烈翻转和高的切变,达到最佳的混合效果。
回转系统是完成混合功能的关键系统,其中回转电机采用低速大扭矩减速电机,是主机混合的动力装置。在回转轴总成上装有感应元件,当回转体转到设定位置后,安装于机架上的感应器发出采样信号,该信号通过PLC系统,读取料斗转速和位置信息,不断在触摸上显示转速和累记转数,并按设定的时间发出停机指令。料斗停止回转,并在制动电机作用下料斗停在最佳的出料位置。
电气控制系统主要分为装于机架内的电器柜和传感器两部份。核心控制器件PLC控制器和变频器安装在电气控制柜中,在使用过程中,电器操作主要是在电气控制柜的操作面板(触摸屏)上完成的,包括打印机、触摸屏、电源开关和急停开关。触摸屏界面上能显示运行时间,转速。
Features
The laboratory mixer is installed on a moveable base. Its main parts include machine frame, rotation system, electric control system, hopper, etc. The conical mixing hopper is mainly composed of hopper, hopper cover, ferrule, butterfly valve, etc.
The hopper that can rotate at 360° is installed on the rotation shaft by adopting the cantilever fixing mode. As the symmetrical axis of the hopper forms an included angle with the rotary arm rotation axis, different components of materials will make three-dimensional movement in the closed hopper, producing strong turning and high shearing and achieving the best mixing effect.
The rotation system is a key system for completing the mixing function. The rotary motor is a low speed high torque speed reducing motor, which is the power unit for mixing. The rotation shaft is installed with sensing components. When the gyrator turns to the set position, the sensor installed on the machine frame sends the sampling signal. The signal passes through the PLC system, which reads the hopper rotation speed and position information, continuously displays rotation speed and accumulated number of revolutions on the touch screen, and sends stopping instructions according to the set time. The hopper stops rotation, and stops at the best discharging position under the action of the brake motor.
The electric control system is mainly composed of two parts such as the electric cabinet and sensor. The core control parts PLC controller and frequency converter are installed in the electric control cabinet. During the use, the operations of electric appliances are mainly completed on the operation panel (touch screen) of the electric control cabinet, including printer, touch screen, power switch and emergency stop switch. The touch screen displays running time, rotation speed,
