SYSTEM FOR DOSING ADDITIVES IN RECRYSTALLIZED SALT

摘要

The invention relates to a system for dosing additives in recrystallized salt, to be used in the industry of processing underground-extracted salt. According to the invention, the system consists of two bars of LEDs having the role of infrared emitter and receiver, which are mounted on a transparent tube (), so that the signal transmitted by the emitter is received by the receiver in the absence of salt, the so received signal being transmitted, through a signal conversion circuit (), to a micro controller () having a multiplexer function, employed at the input of a programmable logic controller (), while, at the output of the micro controller (), another signal conversion circuit () is employed, of two electrically-operated valves (), i.e. one valve for removing the substance from the transparent tube and the other one for dosing additives in an additive-containing recipient (), the dosing being performed on a conveyor belt ().
