Turntable type continuous liquid charging device

Abstract

The invention discloses a turntable type continuous liquid charging device and belongs to the technical field of rare earth extraction. The technical key point is that: the device comprises a box body, wherein the bottom of the box body is provided with a reservoir; a side wall of the reservoir is provided with a liquid inlet pipe communicated with an external liquid supply source; a liquid receiving tank is formed on a side wall of the box body above the reservoir; a side wall of the liquid receiving tank is provided with a liquid outlet pipe; a rotating shaft is arranged in the middle of the box body; an external end of the rotating shaft is connected with a driving device; a turntable is arranged on the rotating shaft in the box body; a plurality of liquid taking mechanisms are uniformly distributed on the turntable; liquid taking openings of the liquid taking mechanisms are soaked in the reservoir in turn along the rotation of the turntable; and liquid outlets of the liquid takingmechanisms are positioned above the liquid receiving tank. The invention provides a turntable type continuous liquid charging device which is simple in structure and continuous, stable and accurate in liquid charge; and the device is used for rare earth extraction separation.

Description

technical field [0001] The invention relates to a liquid adding device, more specifically, to a rotary disk type continuous liquid adding device for rare earth extraction and separation. Background technique [0002] During the extraction and separation process, continuous, stable and accurate liquid feeding is the key to achieve the predetermined extraction and separation effect. At present, the devices for continuous and stable feeding of liquid materials in extraction and separation include: (1) Throttle valve, which controls the opening of the valve manually or mechanically, thereby changing the liquid flow section to adjust the feeding amount, but the feeding amount is easily affected by the feeding liquid. (2) Quantitative pumps have a large investment, especially large flow quantitative pumps, which are expensive, difficult to bear, and difficult to maintain, requiring power and high operating costs. Contents of the invention [0003] The purpose of the present inv...
