LIQUID DE-ICER PRODUCTION APPARATUS AND METHOD

摘要

An apparatus and method for automatically producing a desired specific gravi ty of a salt solution used for deicing highways. Highway departments can produc e a high volume of salt solution of a desired specific gravity by a machine that automatically feeds salt and water into a hopper tank to produce brine, then automatically measures and adjusts the specific gravity of the brine by adding greater or lesser amount s of fresh water to the brine removed from the hopper tank. The salt added to the hopper tank contains impurities, which are removed by self-cleaning strainers. The sediment so removed flows to a trash tank. Sediment in the trash tank settles to the bottom thereof an d the liquid collected is filtered by another set of self-cleaning strainers such that liquid from the trash tank can be sent to the hopper tank. The device automatically records the specific gravity of the solution produced.
