PURPOSE: A device for supplying a calcium chloride solution which is used to melt the frozen road surface, is provided to supply a calcium chloride solution in a rapid and continuous way by carrying out dual operation which includes the steps of supplying a calcium chloride solution to a storage tank and supplying a stored calcium chloride solution to a spray. CONSTITUTION: The device for supplying a calcium chloride solution in a device for preparing a calcium chloride solution(1) comprises: a storage tank(10) for the calcium chloride solution prepared in the preparation device; a pressurizing pump(20) which selectively carries out a dual operation of supplying the calcium chloride solution from the preparation device to the storage tank or from the storage tank to a spray; first(21) and second(22) solenoid valves which are placed between each of the preparation device, the pressurizing pump and the storage tank to control the supply or block of the calcium chloride solution to the storage tank by simultaneous open or shut in a selective way; and third(23) and fourth(24) solenoid valves which are placed between each of the storage tank, the pressurizing pump, and a supplying tube(25) to control the supply or block of the calcium chloride solution to the spray by simultaneous open and shut in a selective way. |
