Embodiment Construction

[0031] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0032] figure 1 figure 2 image 3 It is the first embodiment of a kind of granulated salt of the present invention, and described granulated salt adds 0.1~0.2% by weight of sodium citrate and 0.02~0.03% by weight of dedecylphenoxyether to sodium chloride Sodium diphenylsulfonate, the moisture content of finished product is 0.5~1.5%; Comprising upper spherical crown 11 and lower spherical crown 12, there is process section 13 between upper and lower spherical crown 11,12, and the cross-sectional shape of process section 13 is The four corners of the process section 13 are square, and the four corners of the process section 13 have circular arc transition se...

Abstract

The invention relates to granulated salt. The granulated salt is formed by adding sodium citrate and decylphenoxy ether sodium dibenzenesulfonate in sodium chloride, wherein the granulated salt comprises an upper spherical crown part and a lower spherical crown part; a technological section is arranged between the upper spherical crown part and the lower spherical crown part; and the section of the technological section is in the shape of a regular polygon. The invention further relates to a special mold for producing the granulated salt. The special mold comprises a double-roller granulating mechanism, wherein the double-roller granulating mechanism comprises a first roller body and a second roller body which have same shape and are symmetrically arranged; the shape of a cavity formed when mold assembly process is carried out on the first roller body and the second roller body is the same as that of the granulated salt. The hardness of the granulated salt product can reach more than 20N, therefore, the granulated salt product can not generate the phenomenon of salt bridges or disintegration in the dissolving process in application; due to the introduction of citrate, the capacity for removing iron ions of the granulated salt can reach 760 mu g / L, while the capacity for removing iron ions of common granulated salt is only 160 mu g / L; and the optimized design of the special mold enables the flange of the granulated salt product to be very small and the granules to be full.

Description

technical field [0001] The invention relates to the technical field of salt for water treatment, in particular to a granulated salt and a special mold thereof. Background technique [0002] The natural crystallization of sea salt has large particles, low cost, and has the advantages of a large sales radius and no agglomeration. However, it contains bromine, which is toxic to water treatment resins, so it cannot be used as a water treatment agent, especially a high-grade water treatment agent. In recent years Later, with the improvement of urbanization in our country, people have higher requirements for high-rise secondary water supply and drinking water, and the demand for high-grade water treatment salt is increasing. Vacuum salt has become water because it does not contain bromine. First choice for handling salt for granulation. [0003] Softened water equipment is composed of strong acid sodium ion cation resin, salt tank and water softener accessories. Send instruction...
