Operating procedures for Pot Tending Assembly
1. After getting to the cab of the Pot Tending Machines, lift the ladder to make the upper limit switch act.
2. Turn on the power switch, check whether the emergency stop button is turned on, turn on the key switch, press the power switch button, and the power indicator lights up.
3. Before walking large and small cars, ring the bell first and the alarm light is on.
4. The right operating lever controls the crane to move forward and backward, and the crane speed is divided into four levels. The front and rear direction of the left operating rod controls the traveling of the trolley. The trolley is divided into two speeds. After the suction and discharge pipes are put down, the speed of the trolley and the trolley is Zui low.
5. The switches of the suction and discharge pipes are selected on the right operation cabinet. The left operation lever controls the lifting of the suction and discharge pipes in the left and right directions. The lifting height of the suction and discharge pipes is controlled by the driver.
6. During material suction, the discharge valve of the silo is closed, the vacuum pump button is opened, and the pressure of -0.012mpa - -0.02mpa is displayed on the touch screen. At this time, material can be sucked. When the pressure exceeds -0.025 MPa, stop the suction and check whether there is a material block blocking the suction port.
7. When the suction temperature is higher than 60 ℃, the cooler is opened. The cooler is controlled by the button on the operation cabinet. The suction temperature shall not be higher than 300 ℃.
8. When the pressure difference between the air inlet and outlet of bag filter exceeds the normal value (0.003mpa-0.005mpa), the vibration motor will open automatically, and the opening time of vibration motor is 20 seconds. If the vibration motor is not opened automatically, it can be opened manually and controlled by the vibration motor button switch on the left operation cabinet. The pressure value and vibration time are displayed on the touch screen.
9. When the high material level of the silo gives an alarm, no more material can be sucked.
10. High material level alarm of cyclone or bag filter, drive the crown block to the specified discharging position, and open the cyclone valve and bag filter valve at the same time for discharging.. The control button is on the right operation cabinet.
11. When sucking, the deflection range of the suction pipe shall not be too large to avoid damaging the suction pipe or the roasting furnace chamber. When the deflection limit of the suction pipe works, it is necessary to stop or reverse the travel of the crane and trolley to the limit switch.
12. The operation status of each parameter is displayed on the touch screen, including the pressure of two pressure transmitters and the temperature of four thermocouples; There are also operation status and alarm display of each motor, including silo discharge valve, cyclone discharge valve, bag filter discharge valve, three fans of cooler, two vibrating motors and vacuum pump. The pressure and temperature values vary with the.
