Description

Technical Field

[0001] The utility model relates to the field of metal waste liquid recovery equipment, in particular to a liquid alkali feeding system. Background Art

[0002] Liquid alkali sodium hydroxide is usually used in the recycling of metal waste liquid. The loading process of liquid alkali sodium hydroxide is generally to first drive the transport tank truck loaded with liquid alkali to the designated loading point in the factory area, and then use the lifting pump at the designated loading point to lift the liquid alkali in the transport tank truck to the liquid alkali storage tank in the factory.

[0003] For example, patent CN 204454549 U discloses a liquid alkali unloading device. During the unloading process, the buffer box constitutes an intermediate storage structure between the liquid alkali truck and the alkali storage tank. The alkali liquid in the liquid alkali truck is first unloaded into the buffer box under the action of gravity, and then the liquid alkali is extracted from the buffer box by a delivery pump and delivered to the alkali storage tank to ensure the continuity of the alkali liquid delivery.
