Embodiment 1

[0033] The device of this embodiment comprises a loam cake 7, a bottom 2, and a cylinder body 8. The stirring paddle 5 is fixed on the center of the loam cake 7 by a shaft seal structure, and the agitation paddle is in the cylinder body; the bottom 2 includes a concave shell 9 , microporous filter plate 1, liquid outlet 4, the top of the concave shell is covered with a microporous filter plate 1 made of hydrophobic material, and the bottom of the concave shell is provided with a liquid outlet 4; the upper cover 7 is provided with the air inlet 6 that connects air compressor.

[0034] A vacuum pipeline or an air pressure pipeline is connected to the liquid outlet 4 to restore the hydrophobic performance of the microporous filter plate 1 . During use or after a period of time, if the hydrophobicity of the microporous filter plate is reduced due to the contamination of the treatment solution, the air compressor can be turned on to pass through the liquid outlet, and the hydrophob...

Embodiment 2

[0038] The device of the present embodiment comprises a loam cake 7, a bottom 2, and a cylinder body 8, and the stirring paddle 5 is fixed on the center of the loam cake 7 by a shaft seal structure, and the agitating paddle is in the cylinder body; the bottom comprises a concave shell 9, The microporous filter plate 1 and the liquid outlet 4 are covered with a microporous filter plate 1 made of hydrophobic material on the top of the concave shell, and the bottom of the concave shell is connected with a vacuum device or a pressure pipe to discharge the liquid Mouth 4.

[0039] The microporous filter plate 1 is tightly embedded in the upper end of the concave shell 9 of the device through a sealing ring.

[0040] The cylinder 8 is openably connected to the bottom 2 and can be quickly opened or closed. In the closed state, the cylinder becomes a flat-bottomed reactor. Opening the bottom is conducive to overall cleaning and cleaning.

example 1

[0042] Example 1 Add a solid tungsten sinking agent into the device of the present invention equipped with tungsten and molybdenum acidic solution, and the original composition of the solution is WO 3 3.32g / L, Mo 2.23g / L, P~15g / L, HCl 1.7mol / L, after heating to 70°C, add 3 / 1000 tungsten precipitation agent, stir slowly for 20 minutes, and then age for 240 Minutes, then pass through the compressed air to filter, then stir and wash with a small amount of water, after the compressed air is filtered, start the openable connection setting at the bottom of the cylinder of the present invention, open the bottom shell 2, and the sediment will fall into the pre-placed receiver. Analyze the filtrate composition as WO 3 0.216g / L, Mo 1.945g / L, P 14.71g / L, HCl 1.7mol / L. Precipitation component is WO 3 48.75%, Mo 5.72%.

Abstract

The invention relates to a reaction and solid-liquid separation integrated device which is developed based on long-term engagement in research on separation of wolfram and molybdenum and liquid-solid multiphase reaction, can be used in various liquid-solid multiphase reaction processes such as ion exchange, adsorption, sedimentation, crystallization, displacement, and the like, and is successfully applied for the first time in separating and reclaiming wolfram or molybdenum from wolframate solutions. The reaction and solid-liquid separation integrated device comprises an upper cover, a bottom and a cylindrical body. A stirring paddle is fixed in the center of the upper cover by an axial seal structure and is arranged in the cylindrical body; the bottom comprises a concave shell, a microporous filter plate and a liquid outlet; the microporous filter plate made by hydrophobic materials is arranged on the top of the concave shell, and the liquid outlet is arranged at the bottom of the concave shell; an air intake connected with an air compressor is arranged on the upper cover. The reaction and solid-liquid separation integrated device can considerably reduce loss of a solid phrase or loss of comparatively high-value substances contained in a liquid system during solid-liquid separation.

Description

technical field [0001] The invention relates to an integrated device for reaction and solid-liquid separation, which is used for ion exchange resins or other adsorbents and precipitants to complete the operations of extracting, enriching and separating various ions from solutions. Background technique [0002] The method of ion exchange to extract, enrich and separate various ions from the solution is a solid-liquid multiphase reaction system. [0003] The equipment for ion exchange operation can be roughly divided into four categories: fixed bed, moving bed, fluidized bed and stirred bed. The height of the resin layer in the fixed bed can be very different, and the resin layer height less than 1m is called a shallow bed; the basic feature of the moving bed is that the resin in a densely packed shape is carried out in a ring column or between two or more columns connected in series. Transfer; the basic feature of a fluidized bed is that the resins are out of contact with ea...
