Example one

Referring to fig. 1, an adsorption dewaxing device for industrial white oil production, compared with the traditional drum-type and centrifugal dewaxing devices which adopt adsorption dewaxing structures, can effectively reduce vibration and energy consumption, the specific structure comprises a tank body 1, a stirring motor 2 and an adsorption oil scraping part 3, wherein the tank body 1 is of a hollow structure, the top of the tank body is provided with a white oil inlet pipe 13 and a dewaxing agent inlet pipe 14, the lower part of the tank body 1 is provided with a white oil outlet pipe 12, the top center of the tank body 1 is provided with the adsorption oil scraping part 3, the bottom of the tank body is provided with the stirring motor 2, the top of the stirring motor 2 is provided with a stirring blade 21 and drives the white oil in the tank body 1 to rotate, the adsorption oil scraping part 3 comprises an oil scraping cylinder 34, a rotating shaft center 31 and a driven adsorption sleeve 33, the oil scraping cylinder 34 is fixed at the top center of the tank body 1, the drive shaft of scraping oil cylinder 34 stretches into jar body 1 downwards and drive pivot maincenter 31 vertical motion, the effect of scraping oil cylinder 34 is according to the position adjustment of the liquid level position of white oil absorption wax, thereby better absorption wax, pivot maincenter 31 is for containing the tree-shaped branch structure of a plurality of circumference arrangement pivots and rotate in the pivot and be connected with corresponding driven adsorption sleeve 33, the winding has multilayer wax adsorption material on the driven adsorption sleeve 33, when agitator motor 2 started, dewaxing agent and white oil reaction and form floated wax layer on the top layer, white oil and the wax on top layer are driven by stirring vane 21 and are produced rotatoryly, driven adsorption sleeve 33 is driven by fluidic rotation and is taken place to rotate and adsorb wax, after wax is cleared up the completion, operating personnel open white oil discharging pipe 12 and emit white oil, thereby accomplish the operation of white oil's absorption dewaxing.

The specific working steps are as follows:

1. an operator injects industrial white oil into the tank body 1 through the white oil feeding pipe 13, then adds a dewaxing agent into the tank body 1 through the dewaxing agent feeding pipe, and carries out mixed reaction on the white oil and the dewaxing agent so as to dewax the white oil.

2. And then starting the stirring motor 2, forming a rotating liquid flow in the tank body 1 at the moment and forming a vortex on the surface liquid level, then starting the oil scraping cylinder 34, lowering the rotating shaft center 31, ensuring that the driven adsorption sleeve 33 is contacted with the surface liquid level of the white oil, and because the wax is lighter than the white oil and can float on the surface of the white oil, the driven adsorption sleeve 33 can fully adsorb the floating wax on the surface of the white oil at the moment, so that the wax is removed.

3. When wax is removed, the operator opens the white oil discharge pipe 12 and discharges the white oil, and then replaces the driven adsorption sleeve 33 to ensure the wax adsorption effect next time.
