In a further preferred structure, the folded plate is provided with a connecting hole, and the connecting rod is fixedly connected with the connecting hole through a fixing bolt.
In a further preferred structure, the inclined plate packing device is fixed in the separator through a steel structure framework.
Furthermore, the separator comprises an inner tank or an outer tank, and inclined plate packing devices are respectively arranged in the inner tank and the outer tank.
The material that mixes with waste lye gets into the inner tank earlier from the material import and advances if and separate, and the folded plate surface of swash plate filler device in the inner tank flows after the seperating fluid gets into the separator, has increased the area of subsiding, has realized the preliminary effective separation of organic phase and waste lye. The first-stage light material enters the outer tank from the first-stage light material outlet and further flows on the surface of a folded plate of the inclined plate filling device of the outer tank to carry out secondary separation, and alkali liquor remained in the light material is further separated. The separation liquid flows on the surface of each layer of folded plates after entering the separator, thereby increasing the sedimentation area and realizing the effective separation of the organic phase and the waste alkali liquor.
The utility model discloses produced beneficial effect does for prior art.
The utility model overcomes the separator volume is less in the original separator, and the poor problem of useless lye separator effect forms a plurality of caves in and protruding between the polygonal folded plate through the increase separation area of swash plate filler device maximize, and the angle that forms between the folded plate makes organic phase and inorganic phase stop more easily at 55-125 or 235 within range of adding materials 305, and then separates, has improved the effect of separation. The separator is divided into an inner layer and an outer layer, and each layer is provided with the inclined plate filling device, so that the materials are separated more thoroughly after two separation processes, and the separation area is increased in the effective separator through the structure of the folded plate, the separation effect is effectively improved, the total solid content is reduced, the consumption of the xanthone benzene is reduced by at least 5Kg, the alkali consumption of the xanthone is reduced by at least 3Kg, and the economic benefit is improved.
