平转浸出设备

REO系列平转浸出器适合于高含油料的预榨浸出和低含油料的直接一次浸出，该设备由于采用不锈钢固定栅板代替易损坏变形的假底结构，具有设备紧凑、运行平稳、故障率低、浸出效率高等优点。

The REO series rotary extractor is suitable for pre pressing leaching of high oil content materials and direct leaching of low oil content materials. Due to the use of stainless steel fixed grid plates instead of easily damaged and deformed false bottom structures, this equipment has the advantages of compact equipment, stable operation, low failure rate, and high leaching efficiency.

平转浸出器的浸出过程及工作原理

    被浸出的油料由封闭绞龙送入料格。封闭绞龙中有一段充满整个绞龙壳的油料，形成料封，防止溶剂蒸汽外溢。

转动体由无级变速机或变频调速机控制，可灵活调节浸出器的转速，从而调节浸出时间。传动部件既可采用齿条传动，也可采用双排滚子链。装满油料的料格按一定方向转动，依次受到循环泵抽上来的不同浓度混合油的间歇喷淋，即每个料格经一个喷淋管喷淋一定时间，待喷下的混合油渗透完，又转到下一个喷淋管处进行喷淋。喷淋形式采用“自喷自”的大流量循环喷淋方式，喷下的混合油浓度由浓到稀，直至最后经新鲜溶剂喷淋。平转浸出器内当混合油喷淋量大于它渗滤过料层的量，则料层表面会短时间积一层混合油，油料处于浸泡状态。料格转过喷淋位置，积存的溶剂渗滤完，此时料层处在渗滤状态。渗滤过料层的混合油，一部分汇集到前一个油斗，一部分仍回到原油斗，从而使混合油不断向前流动。各油斗中混合油浓度呈“阶梯状”，依次升高。料格依次转到新鲜溶剂喷淋管处时，浸出格内的油料经最后一次新鲜溶剂喷淋和最后滴干，然后就转到出料格的位置。因此，油料在浸出器内被混合油喷淋、滴干、再喷淋、再滴干，经过若干次浸出，最后经新鲜溶剂喷淋、滴干。混合油的流向和油料的流向是处于逆流状态。

The leaching process and working principle of a rotary extractor

The extracted oil is fed into the material compartment through a closed auger. There is a section of oil filled with the entire shell of the closed dragon, forming a material seal to prevent solvent vapor from overflowing.

The rotating body is controlled by a continuously variable speed machine or a variable frequency speed control machine, which can flexibly adjust the speed of the leaching machine, thereby adjusting the leaching time. The transmission components can be either rack driven or double row roller chain driven. The material grid filled with oil rotates in a certain direction and is subjected to intermittent spraying of different concentrations of mixed oil pumped up by the circulation pump. That is, each material grid is sprayed through a spraying pipe for a certain period of time. After the sprayed mixed oil has penetrated, it is then transferred to the next spraying pipe for spraying. The spraying form adopts a "self spraying" high flow circulation spraying method, where the concentration of the mixed oil sprayed increases from thick to thin until it is finally sprayed with fresh solvent. When the amount of mixed oil sprayed in the rotary extractor is greater than the amount it has filtered through the material layer, a layer of mixed oil will accumulate on the surface of the material layer for a short period of time, and the oil material will be in a soaking state. The material grid is turned over to the spray position, and the accumulated solvent has infiltrated completely. At this point, the material layer is in a state of infiltration. The mixed oil that has filtered through the material layer is partially collected in the previous oil hopper, while some still returns to the crude oil hopper, causing the mixed oil to continuously flow forward. The concentration of mixed oil in each oil hopper shows a "ladder like" pattern, increasing in sequence. When the material grid is sequentially turned to the fresh solvent spray pipe, the oil in the leaching grid undergoes the last fresh solvent spray and drips dry, and then turns to the position of the discharge grid. Therefore, the oil is sprayed, dripped, sprayed, and dripped with mixed oil in the extractor. After several leaching cycles, it is finally sprayed and dripped with fresh solvent. The flow direction of the mixed oil and the flow direction of the oil material are in a countercurrent state.
