SPKV - Scanner of car position for coking plants
The scanner of car position SPKV-03 serves for accurate command guidance and positioning of Coke Oven Machines (charging car; pusher machine; guide car; quench car or wharf and maintenance cars) to individual coke oven chambers.
Advanges:
- coding plates and sensor head are made of stainless steel
- there is no electronic part in the coding plates
- optical system resistant to dust, smoke and steam (automatic control)
- automatic control of sensor head temperature
- heating system to prevent steam condensation
- prevention of faulty reading of car position
- accurate position measurement even on curved rails +-70 horizontally and +-45 vertically
Merits:
- accurate car positioning
- automatic car shunting
- process control and follow up
Principle of device:
Coding plates are installed in front of individual coke chambers, the sensor head is fixed to the coke oven machine, and the display is installed in the operator's room. An individual number of each plate is optically identified when the coding plate passes through the gap in the sensor head. In the same time the distance from the center of the coding plate is measured. The display allocates the coding plate name to its number, which is then shown in the upper display field. The bottom display field shows the distance from the center of the code plate together with a minus or plus sign. The display has interface with an external communication system (PROFIBUS DP-V0, MODBUS TCP/IP, PROFINET). The entire equipment is very robust and resistant to the adverse conditions of the coke plant environment.
This equipment will facilitate more precise guidance of the coke oven machines/cars, which will result in minimizing the wear and tear of the coke oven chambers. It will also provide an effective synchronization of the cars and automation of car shunting or of the entire coking plant. It can effectively control the whole coke production process.
Digital display
- display of position No. of chamber/name
- distance range from the axis of the coding plate: ± 350 mm
- accuracy: 1 mm
- contains interfaces to communicate with PLC and for connection to the encoder IRC
