Description

Salt dissolving device for sodium hypochlorite generator Technical Field The utility model relates to the technical field of sodium hypochlorite production equipment, in particular to a salt dissolving device for a sodium hypochlorite generator. Background Salt dissolution is an important unit system of complete equipment of sodium hypochlorite generators, and generally consists of a water softener, a salt feeding machine and a salt dissolution tank. The water softener is a water source for providing calcium and magnesium ions for dissolving salt, the salt feeding machine is used for feeding solid salt into a salt dissolving tank, the salt dissolving tank is a container for dissolving salt, and a corrosion-resistant plastic tank body made of food-grade PE materials and the like is generally selected. The lower part in the salt dissolving tank is also provided with a salt layer supporting plate, a salt layer supporting plate filter screen and a salt water filter, and the salt water filter is arranged below the salt layer supporting plate, namely at the bottom of the salt dissolving tank. The brine filter directs the saturated brine directly to the dilute brine preparation system through a horizontal conduit at the bottom of the tank. In order to ensure the purity of saturated saline water sent out by the salt dissolving tank, the mesh number of the filter screen of the salt water filter which is generally selected is large, namely the aperture of the filter screen is small, the filter screen is easy to be blocked by impurities in salt after a period of operation, and the filter screen of a salt layer supporting plate made of plastic materials such as PVC (polyvinyl chloride) is damaged after being used for a long time, so that the operation of a follow-up dilute saline water configuration system is influenced, and even the sodium hypochlorite generator is stopped. Therefore, tedious cleaning and replacing work of the filter screen are required, and time and labor are wasted. Based on the above, the present utility model provides a salt dissolving device for sodium hypochlorite generator to solve the above problems.
