Problems solved by technology

[0004] However, due to the fact that the technical level of the horizontal rotary extractor has not been greatly developed in recent decades, the oil yield rate is low, the steam consumption is large, the residual oil in the meal after leaching is high, and the concentration of mixed oil is low, which has been unable to meet the requirements. The production needs of the modern oil industry, therefore, how to improve the existing horizontal extractor to improve its extraction efficiency and the quality of the obtained mixed oil is a technical problem to be solved by those skilled in the art

Embodiment Construction

[0013] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The horizontal rotation extractor provided by the present invention is cylindrical, and its internal structure is laid out as follows: figure 1 As shown, its main oil spray pipe 1, 20 leaching rotary grids 2, 7 oil collecting grids 3 and mixed oil circulating oil pump 5 are composed. Each oil-collecting grid 3 is separated by an oil-collecting grid partition 4 (the partition between the first and second oil-collecting grids 3 is very low, and is actually in a connected state, which can also be regarded as a grid).

[0015] There are 14 spray pipes 1 in total, of which the first 12 are sprayed with mixed oil, the last two are sprayed with fresh solvent, and the 14 spray pipes 1 are evenly distributed in the range of 0-270° abo...

Abstract

The invention discloses a rotocel extractor. The rotocel extractor comprises extracting rotation grids, oil collecting grids, mixed oil circulating oil pumps and 12 to 14 spraying pipes, wherein the extracting rotation grids are annularly and uniformly distributed in the rotocel extractor; the spraying pipes are uniformly distributed in the 0 to 270-degree area above the extracting rotation grids; the oil collecting grids are positioned below the extracting rotation grids and each oil collecting grid corresponds to the positions of two spraying pipe; one end of each oil circulating oil pump is connected with one oil collecting grid and the other end is connected with the two spraying pipes with the positions corresponding to the oil collecting grid; the height of clapboards of the oil collecting grids takes up 1 / 8 to 1 / 10 of the whole rotocel extractor. The rotocel extractor is compact and reasonable in structure, the working efficiency of the rotocel extractor can be effectively improved, the energy consumption and oil residual amount in dregs are reduced, and the quality of mixed oil is improved.

Description

technical field [0001] The invention relates to the technical field of oil refining, in particular to a flat-rotating extractor. Background technique [0002] Leaching is one of the most critical processes in the oil refining process. It uses the mutual solubility of oil and solvent. The solvent penetrates into the solid oil and dissolves the oil to form a thick miscella. Due to the concentration difference, the thick miscella inside the solid oil diffuses. Into the thin oil mixture on the outside to extract the fat. [0003] The main equipment in the leaching process is the extractor. The main extractors currently in production can be divided into horizontal rotary extractors, ring extractors and drag chain extractors. Among them, the horizontal rotary extractor is the most common in small and medium-sized oil plants. The interior of the horizontal extractor is a cylindrical structure, and there are 18-20 rotating grids evenly distributed inside. There are about 6 spray p...
