Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon production, in particular to a mixing device for producing phosphoric acid from activated carbon. Background Art

[0002] Activated carbon is amorphous carbon in black powder or block, granular, or honeycomb form, and there are also regularly arranged crystalline carbon. In addition to carbon, activated carbon also contains two types of admixtures: one is chemically combined elements, which remain in the carbon due to incomplete carbonization, or during the activation process, foreign non-carbon elements chemically combine with the surface of activated carbon; the other type of admixture is ash, which is the inorganic part of activated carbon. Ash in activated carbon can easily cause secondary pollution. Activated carbon is widely used in production and life because of its strong adsorption capacity; and in the process of stirring activated carbon and nitric acid, the concentration is too high due to different proportions and needs to be added manually, which wastes manpower.

[0003] A Chinese patent (authorization announcement number: CN109395634A) proposes a phosphoric acid mixing device for producing activated carbon, including a base, support frames are fixedly installed on both sides of the top of the base, the tops of the two support frames are fixedly connected to both sides of the bottom of the mixing drum, a feed port is provided on one side of the top of the mixing drum, a feed hopper is fixedly installed on one side of the feed port, a liquid inlet is provided on the other side of the top of the mixing drum, and a liquid inlet pipe is inserted inside the liquid inlet. The invention provides a phosphoric acid mixing device for producing activated carbon, which drives the rotating shaft to rotate by an installed driving motor, so that the activated carbon and phosphoric acid in the mixing drum are fully mixed; the installed air pump is used to ventilate when the activated carbon and phosphoric acid are mixed to avoid precipitation of the activated carbon and affect the mixing effect; the installed nozzle is used to facilitate the thorough cleaning of the mixing drum and the rotating shaft after mixing, so as to avoid the mixture of activated carbon and phosphoric acid remaining on the inner wall of the mixing drum and the surface of the rotating shaft.

[0004] In the above scheme, since only the activated carbon and nitric acid are stirred, and the inside of the barrel is only cleaned after the stirring is completed, the activated carbon and nitric acid liquid cannot be adjusted during the stirring process, and nitric acid liquid needs to be added manually. In order to solve the problem that nitric acid liquid cannot be added automatically, we propose an activated carbon production phosphoric acid mixing device. Utility Model Content

[0014] The invention discloses a phosphoric acid mixing device for producing activated carbon. When the viscosity between nitric acid liquid and activated carbon increases, the resistance will increase when the shrinking bellows sleeve rotates. At this time, the shrinking bellows sleeve shrinks, and the gas inside the shrinking bellows sleeve enters between the first rotating disk and the inside of the vertical tube.
