Oil slag separation and re-squeezing device for middle and small-sized oil squeezing machine

Abstract

The invention discloses an oil slag separation and re-squeezing device for a middle and small-sized oil squeezing machine. The oil slag separation and re-squeezing device comprises a crude oil box arranged under a crude oil outlet of the oil squeezing machine; the crude oil box is arranged on a machine frame of the oil squeezing machine; a crude oil filtering screen is arranged above the crude oilbox; a first skimmer is arranged above the crude oil filtering screen; a second skimmer is arranged at the inner bottom of the crude oil box; one side of the crude oil box is provided with a slag collecting groove; the slag discharging ends of the first skimmer and the second skimmer are respectively communicated with the slag collecting groove; an oil slag lifting mechanism is arranged in the slag collecting groove; the slag discharging end of the oil slag lifting mechanism is communicated with the feeding end of the oil squeezing machine. The twice oil slag separation is realized through the filtering by the crude oil filtering screen and the clarification of the crude oil box; the oil slag in the crude oil is separated to the maximum degree; the oil slag separation effect is good; theoil slag separation efficiency is high; the equipment occupied area is small; the automation degree is high; the work intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to oil pressing equipment, in particular to a device for separating and repressing oil residue for small and medium-sized oil presses. Background technique [0002] The crude oil extracted by screw pressing method contains a large amount of oil residue, and the oil content in the oil residue is very high. Large-scale oil factories generally use the method of slag removal machine-oil tank-scraper to clean most of the oil residue in the crude oil and concentrate it back to squeeze, but this method requires a lot of equipment, is expensive, and requires a large site, which is not suitable for medium Small oil press processing oil residue. At present, most of the oil residues of small and medium-sized oil presses are repressed manually, which has the problems of low efficiency, high labor intensity, and large space requirements. As the country actively promotes localization of production and the needs of automated oil processing pro...

Problems solved by technology

Large-scale oil factories generally use the method of slag removal machine-oil tank-scraper to clean most of the oil residue in the crude oil and concentrate it back to squeeze. However, this method requires a lot of equipment, is expensive, and requires a large site, so it is not suitable for medium Small oil press processing oil residue

At present, most of the small and medium-sized oil press oil residues are pressed manually, which has the problems of low efficiency, high labor intensity, and large space requirements.
