Technical Field

[0002] The solid-liquid separation of heavy alkali is one of the important processes in the production of combined alkali. This process not only plays the role of separating the heavy alkali solid and the mother liquor in the production process, but also the salt washing part plays a key role in the mother liquor balance of the entire combined alkali production. At present, the solid-liquid separation of heavy alkali usually adopts a belt filter, which separates the mother liquor from the solid-liquid mixture during production. After searching: Patent No. CN202139065U is an improved device for solid-liquid separation of heavy alkali, which includes a belt filter, the mother liquor outlet of the belt filter is connected to the inlet of the first mother liquor reflux pipe with a valve installed thereon, the outlet of the first mother liquor reflux pipe is connected to the liquid inlet of the mother liquor separator, the bottom liquid outlet of the mother liquor separator is connected to the inlet of the second mother liquor reflux pipe with a valve installed thereon, the second mother liquor reflux pipe is connected to the inlet of the third mother liquor reflux pipe, and the first mother liquor reflux pipe and the third mother liquor reflux pipe are connected through a fourth mother liquor reflux pipe with a valve installed thereon.

[0003] However, the above-mentioned heavy alkali solid-liquid separation device still has some shortcomings. The separated heavy alkali solid stays and adheres to the top of the filter belt, which easily causes blockage of the filter belt, thereby reducing the solid-liquid separation effect. After the solid-liquid separation of the heavy alkali material, the heavy alkali solid still contains moisture, which makes it inconvenient to effectively dry the heavy alkali solid, thereby reducing the dehydration effect of the heavy alkali solid. Therefore, we propose a solid-liquid separation equipment for dehydrating heavy alkali materials to solve the above problems. Utility Model Content
