Embodiment Construction

[0027] As shown in the accompanying drawing, the first extraction process to the first batch of raw materials: open valve 2, valve 3, start pump 4, the fresh solvent in the solvent tank 1 is input in the sealed band stirring leaching tank 5, the solvent weight is 7 times the weight of the oil contained in the oily clay or diatomite, after the solvent is delivered, close the valve 2, the valve 3, and the pump 4; start the motor 16, put the oily clay or diatomite into the feed port 15, and pass through the twisted Long 17 enters the sealed leaching tank 5 with agitation. After the feeding is completed, turn off the motor 16; start the motor 6 for the first stirring extraction, and after stirring for 10 to 15 minutes, turn off the motor 6 for natural precipitation; settling for 40 to 60 minutes Afterwards, open the solid-liquid separation valve 11, valve 12, valve 18, input the concentrated mixed solution into the temporary storage tank 22 of the concentrated mixed solution with s...

Abstract

The present invention relates to method and apparatus for extracting oil from edible oil decolorizing clay, lubricating oil decolorizing clay and oil bearing diatomite. The method includes the following steps: 1. mixing No. extracting solvent oil or n-hexane with oil bearing clay or diatomite; 2. thrice extracting oil from the clay or diatomite via natural precipitation process; 3. filtering mixed liquid and separating oil from solvent in evaporation unit; and 4. eliminating solvent from the extracted clay or diatomite via steaming or stoving and exhausting clay or diatomite. The apparatus includes sealed leaching tank with stirrer, sealed filter with stainless steel filtering sheets, solvent-eliminating steaming and stoving pot, sealed solid-liquid separator, sealed concentrated mixture liquid storage, solvent tank, evaporator, condensator, etc. The method and the apparatus is for extracting oil from oil bearing clay or diatomite.

Description

Background technique [0001] In the refining process of oleochemical industry, the decolorizing agent activated clay and filter aid diatomaceous earth all contain a certain amount of oil, generally between 20% and 40%. However, manufacturers generally treat these used activated clay and diatomaceous earth as waste, which not only causes environmental pollution, but also causes waste of resources. After repeated experiments and comparisons, the method and equipment were developed. According to the novelty search, no related reports have been seen. Contents of the invention [0002] The object of the present invention is to provide a method and equipment for extracting oil from bleached clay and filtered diatomite in oleochemical industry, the method and equipment can effectively extract oil from oily clay and oily diatomite , reduce environmental pollution, and obtain higher economic and social benefits. The equipment of the invention consumes less solvent, has high oil extr...
