The coarse quartz sand filter layer 22, the fine quartz sand filter layer 23 and the activated carbon purification layer 24 arranged in the purification tank 20 at the bottom of the primary filter box 10 can further filter and purify the brine. The brine conveying pipeline 30 arranged at the top of the primary filter box 10 can convey the brine to the primary filter box 10, and the stand column 31 at the water inlet end of the brine conveying pipeline 30 and the rotating seat 32 coaxially connected at the bottom can play a supporting and connecting role. The multi-layer filtering and purifying device can effectively improve the purification effect of the brine in the salt mining.

[0029] Further, the primary filter box 10 is provided with a liquid collecting hopper 12 at the bottom, and a liquid outlet pipe 13 is arranged between the bottom of the liquid collecting hopper 12 and the top of the purification tank 20, so that the brine after preliminary filtration can flow smoothly and centrally into the purification tank 20, thereby improving the filtering efficiency.

[0030] It is worth noting that the top of the limiting ring seat 14 is provided with a lifting ring 15 in U-shaped cross section, so that the replacement operation of the replaceable filter screen 11 is more convenient, and the user can easily lift and replace the filter screen by the lifting ring 15, thereby improving the maintenance convenience of the equipment.

[0034] The working principle of the multi-layer filtering and purifying device for salt mining is as follows:

[0035] Firstly, the salt water to be treated is introduced through the water inlet end of the salt water conveying pipeline 30; the threaded connector 33 is installed on the water inlet end of the salt water conveying pipeline 30, so as to facilitate the connection with other pipelines or equipment; before the salt water is introduced, the gate valve 35 can be opened to adjust the conveying flow of the salt water;

[0036] Then, the salt water enters the primary filtering box 10; in the primary filtering box 10, the salt water is filtered through the replaceable filter screen 11 to remove larger impurities and particles, and the two groups of replaceable filter screens 11 are used alternately; the limit ring seat 14 is installed on the top of each group of filter screens, so as to ensure the stability of the filter screens and the convenience of replacement; the salt water filtered preliminarily flows into the liquid collecting hopper 12, and then flows into the purifying box 20 through the liquid outlet pipe 13;

[0037] In the purifying box 20, the salt water is sequentially subjected to multi-layer filtering and purifying treatment of the coarse quartz sand filtering layer 22, the fine quartz sand filtering layer 23 and the activated carbon purifying layer 24; these filtering layers can further remove impurities such as small particles, organic matter and peculiar smell in the salt water, thereby improving the purity of the salt water;

[0038] Finally, the salt water subjected to the multi-layer filtering and purifying treatment is concentrated in the collecting hopper 25 at the bottom of the purifying box 20, and is discharged through the discharge pipe 26; at this time, the user can close the gate valve 35 to stop the conveying of the salt water, and can perform subsequent treatment or use on the discharged salt water according to needs.
