Description

Technical Field

[0001] The utility model relates to the technical field of metal sludge recovery, in particular to a metal sludge recovery device. Background Art

[0002] Electroplating sludge refers to the precipitate produced during the treatment of electroplating wastewater, which is mainly composed of heavy metal hydroxides such as copper and chromium, and has a complex composition. Due to the large amount of electroplating wastewater, complex composition, high COD, and high heavy metal content, if it is discharged without treatment, it will cause serious environmental pollution. While treating electroplating wastewater, a large amount of electroplating sludge will also be formed. These electroplating sludges have the characteristics of high water content, high thermal stability of heavy metal components and easy migration. If not properly handled, it is very easy to cause secondary pollution. Acid leaching is the most widely used method in solid waste leaching. For the treatment of industrial wastes such as electroplating, casting, and smelting, sulfuric acid is the most effective leaching agent. It is widely used in the recovery of metal sludge because of its low price, low volatility, and difficulty in decomposition.

[0003] The existing metal sludge recovery device generally adds the electroplating sludge into the acid leaching barrel and performs acid leaching on the electroplating sludge by adding a certain amount of sulfuric acid. After the acid leaching is completed, metal solids are formed and discharged through the discharge port. Another discharge method is to extract the metal solids inside the acid leaching barrel through a sludge pump.

[0004] The disadvantages of the existing metal sludge recovery device are that, since the metal solids are discharged through the discharge port or extracted by the sludge pump, it is difficult to completely clean the metal solids remaining on the inner wall of the acid leaching barrel; furthermore, since the sulfuric acid and the electroplating sludge are not fully mixed, the acid leaching efficiency is low. Therefore, it is necessary to propose a metal sludge recovery device to solve the above-mentioned problems. Utility Model Content

The output ends of the two second electric telescopic rods are fixedly connected to a lifting plate located above the cover plate, and the lifting plate and the cover plate are fixedly connected by two connecting plates.

[0010] In order to facilitate the positioning of the collection frame, as a preferred metal sludge recovery device of the present invention, the upper end of the placement plate is fixedly connected with a positioning frame that fits the outer wall of the collection frame.

[0015] By moving the stirring frame to the top of the acid leaching barrel and then rotating the acid leaching barrel forward, the metal inside the acid leaching barrel can be fixedly poured into the inside of the collecting frame, and then the pushing plate is driven by the first electric telescopic rod to move toward the opening of the acid leaching barrel, and then all the solid metals remaining on the inner wall of the acid leaching barrel can be pushed into the inside of the collecting frame, thereby achieving the effect of preventing the solid metal from remaining on the inner wall of the acid leaching barrel during discharge.
