Salt pan ore drying system for spreading brine

The salt pan comprises a plurality of salt ponds (1), a brine inlet channel (2) and a brine outlet channel (3), the brine inlet channel (2) is arranged on one side of a salt pond group (10), is used for feeding brine, is communicated with the salt ponds (1) in the salt pond group (10) and is provided with a brine inlet gate (22), and the brine inlet channel (2) is further provided with brine guide gates (23) corresponding to the salt ponds (1) at intervals; and the brine outlet channel (3) is arranged on the other side of the salt pond (1), is communicated with each salt pond (1) in the salt pond group (10), and is provided with a brine outlet gate (32) for controlling the on-off of brine. Therefore, by utilizing the structures of the brine inlet channel (2), the brine outlet channel (3), the brine inlet gate (22), the brine guide gate (23), the brine outlet gate (32) and the like which are arranged corresponding to the salt pond (1), brine can be injected into the independent salt pond to be tedded under spe
