Description

The invention relates to the field of chemical, light, food, medical and other industries, and can be used to obtain solutions of mineral salts of various concentrations and compositions.

A device for the preparation of salt solutions containing a container for dissolution, a pipe for supplying water for dissolution in the upper part of the tank, a pipe for draining the finished saturated solution in the lower part of the tank (RF patent for utility model No. 128128, publ. 05.20.2013)

The disadvantage of this utility model is the inability to carry out intensive washing of the filter material.

The closest technical solution is a salt solvent designed to prepare a solution of sodium chloride. The salt solvent is a vertical cylindrical vessel, consisting of the following main elements: a steel cylindrical body with two welded elliptical bottoms, a drain plate, a loading hatch, a pipe with a chipper for supplying and discharging water, a fitting for hydraulic discharge, and filter material. (The information-reference catalog "Water Treatment Equipment", TU 24.03.1569-89. OKP code 31 1322)

The disadvantage of this technical solution is the inability to carry out intensive washing of the filter material, insufficient removal of contaminants.

The objective of this utility model is to achieve the most effective washing of the filter material with the maximum removal of suspended solids and mechanical impurities from it through the use of water-air washing.

The problem is solved in that in the device for the preparation of salt solutions containing a container for dissolving, pipelines for supplying water for dissolving salt into the upper part of the tank, for discharging the finished salt solution and for supplying water for washing in the lower part of the tank, the filter material, inside which there is a drainage system, while the pipeline for supplying water for flushing is equipped with a fitting with a pipe for supplying air.

The figure schematically shows a device for the preparation of salt solutions.

A device for preparing salt solutions contains a dissolution tank 1 with a tubular drainage system 2, a hatch 3 for loading salt, a pipe 4 for supplying water for dissolution, a pipe 5 for draining the finished salt solution, a pipe 6 for supplying water for washing with a fitting 7 for supplying air through the pipeline 8, filter material 9, pipe 10 for draining the wash water, 11, 12, 13, 14, 15, 16 - valves. Through the pipe 4 for supplying water for dissolution fill the tank 1 with water to about half its volume. Through the hatch 3 to load salt produce its backfill. The preparation of a saturated salt solution is carried out by filtering tap water through a fixed layer of sodium chloride, periodically loaded into a container 1 on a filter material 9, inside which a tubular drainage distribution system 2 is located. Saturation of water with salt occurs in the mode of slow filtration of water through a salt layer (0.1- 0.5 m / h). A saturated salt solution is poured into a previously prepared container through a pipe 5 of the outlet of the finished salt solution. Particles of clay, sand and other insoluble impurities coming from the salt added to the salt solvent gradually accumulate in the filter material 9 and should be periodically removed from it as suspended solids accumulate in the filter material 9. Washing is carried out as follows. The valve 11 is closed, and the valves 12 and 16 are opened and the flushing water is supplied to the tank 1 through the pipe 4 to the pipe 6 for supplying water to the washing, then to the pipe 5, and then to the tubular drainage system 2. The valve 13 is closed. The valve 14 is opened. and in the pipe 6 for supplying water for washing, air is supplied through the pipe 8 through the nozzle 7. During the washing of the filter material 9, the valve 15 is open and the washing water is discharged through the pipe 10. Due to the supply of air to the pipe 6 through the pipe 7 through the pipe 8, a turbulent mode is formed the movement of the water-air mixture, characterized by swirls and countercurrents, which contributes to a more intensive mode of mixing the filter material 9 in water, providing it with stable and high-quality cleaning (washing). The frequency of washing the device depends on the quality of the salt used, in particular, on the mass fraction of the residue insoluble in water in it. The problem of using low-grade salt was solved by the use of a “Device for the preparation of salt solutions”, which has a water-air flushing system (tubular drainage system 2, pipe 6 with a nozzle 7 for air supply through pipe 8) by the type of quick water filters, which allows intensive washing of the filter material, providing removal of contaminants, but not filter material, with washing water and washing it not every time after dissolving the salt, but as necessary.
