Description

Technical Field

[0001] The utility model relates to the technical field of high-salt wastewater treatment, in particular to a high-salt wastewater recovery device. Background Art

[0002] In the process of treating high-salinity wastewater, a sedimentation tank is needed to precipitate the wastewater. A large amount of salt, oil or organic heavy metals in the wastewater will be adsorbed on the inner wall surface of the tank. Traditional sedimentation tanks cannot clean the adsorbed substances on the inner wall of the tank, which affects the normal use of the sedimentation tank and causes it to be scrapped.

[0003] The existing Chinese patent CN218046632U discloses a device for recycling high-salt wastewater. When the scraping brush head cleans the inner wall surface of the sedimentation tank, the driving motor drives the threaded rod to rotate. Combined with the meshing transmission of the threaded rod to the lifting platform and the limiting effect of the limiting rod on the lifting platform, the lifting platform can be driven to move up and down along the threaded rod, thereby driving the scraping brush head to move up and down, so as to remove all impurities adsorbed on the vertical inner wall surface of the sedimentation tank.

[0004] However, the above-mentioned high-salt wastewater recovery device sets the threaded rod and the limit rod in the tank body. The high-salt wastewater in the tank body will come into contact with the threaded rod and the limit rod during sedimentation. A large amount of salt, oil or organic heavy metals in the wastewater will be adsorbed on the threaded rod and the limit rod, which can easily cause serious transmission wear between the threaded rod and the lifting platform, and then cause the lifting platform to be stuck.
