The towline extractor is a special equipment for solid-liquid extraction of vegetable oil in small and medium-sized vegetable oil factories (or leaching workshops). This equipment is suitable for leaching of various raw materials, such as primary leaching of soybean germ, rice bran, etc. At the same time, it is also suitable for leaching pre-pressed cakes of vegetable oils such as cottonseed, rapeseed, sesame, tea seed, and tung seed.

How about the drag chain extractor produced by Huatai?

   The transmission layout of Huatai drag chain extractor is composed of three points, namely the driving sprocket, the driven sprocket and the tensioning sprocket. Due to the large horizontal distance between the tensioning wheel and the driving wheel, the reliability of the transmission of the chain and the driving sprocket is formed. Both the main and driven shafts adopt self-aligning roller bearings, which can better compensate the coaxiality error and make the operation of the shafts flexible and balanced. The tension shaft adopts sliding bearings. The extractor scraper is welded to the internal transmission chain, and when the driving wheel rotates, the chain and the scraper are driven to move smoothly, so as to drive the material to move at a uniform speed on the grid.

   The external transmission of the extractor adopts a double-row chain, through two-stage deceleration, using a cycloidal pin wheel reducer, the output speed is n=0.616r/min, through the deceleration of the large and small sprockets, the speed of the main drive shaft is n=0.118r/min min. The tightness of the outer double-row chain is implemented by adjusting the moment arm of the counterweight on the outer tensioner. In order to ensure the sealing performance, the shaft seal parts are sealed with skeleton lip seal rings, which improves the sealing effect.

   The tensioning wheel in the box is used for tensioning the P=400 pitch chain. When the chain is slack, the tensioning shaft tensioning screw sleeve must be loosened, and then the tensioning screw should be rotated to tighten. The judgment of the tightness of the chain is mainly determined by the amount of deflection of the chain at the unsupported part and the torque of the rotating screw. The tightness of the chain should be appropriate.

   Extractor is the core equipment of leaching oil production process, and its quality is directly related to various economic and technical indicators of leaching production. Therefore, it is of great significance to choose a manufacturer specializing in the production of extractors reasonably and correctly to improve the efficiency of leaching production, reduce production costs, and improve the economic benefits of leaching oil plants.
