Abstract

The invention discloses a two-stage integrated composite filter element oil circulation purification device, which comprises an oil tank, a hydraulic pump and a filter connected through a pipeline, and the hydraulic pump transfers the oil to be filtered from the oil tank through the pipeline. The middle suction filter is filtered and then returned to the oil storage device; the filter is filtered by a two-stage integrated composite filter element, the folded filter paper is sleeved on the outer ring of the inner protection tube, and the polyamide filter material is sleeved on the folded filter paper or the outer protection tube. For the outer ring of the tube, the polyamide filter material is made of polyamide material through the melt-blown process. The melt-blown superfine fibers are bonded and entwined to form a polyamide melt-blown non-woven fabric. The polyamide melt The spray non-woven fabric is a loose structure with filter holes arranged on it. The invention has higher filtration precision, dirt holding capacity and oil-water separation capacity, and has the characteristics of oil corrosion resistance, high reliability, etc., and meets the filtering requirements of common oil products.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a circulating filter device for purifying oil products. Background technique [0002] At present, industrial oil products mainly include fuel oil and non-fuel oil. Fuel oil includes gasoline, diesel, ethanol gasoline, etc., and non-fuel oil products include lubricating oil, hydraulic oil, quenching oil or industrial waste oil. During the production, transportation and storage of fuel, a large amount of impurities are generated and mixed, and clean fuel will also produce metal oxides, precipitated gums, bitumen and other pollutants after being stored for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, which will increase fuel consumption and exhaust emissions of fuel-powered equipment after a period of use. Therefore, cleaning is required. The current common solution ...
