Oil product circular purifying device based on universal rotary filter

Abstract

The invention discloses an oil product circular purifying device based on a universal rotary filter. The oil product circular purifying device comprises an oil tank, a hydraulic pump and the filter, all of which are connected through a pipeline. The hydraulic pump sucks an oil product needing to be filtered from the oil tank into the filter through the pipeline, and after being filtered, the oil product flows back into an oil storage device. A thread connecting plate is arranged between an opening part of a filter shell and an oil outlet of a filter element. A plurality of symmetrically-distributed protruding teeth are arranged on the periphery of the thread connecting plate. Grooves matched with the protruding teeth are formed in the opening part of the shell. The circumferential size of the protruding teeth is smaller than that of the grooves. Under the effect of an elastic supporting piece, the thread connecting plate is pressed and attached to the part between the opening part of the shell and the oil outlet of the filter element. According to the oil product circular purifying device, filtering of fuel oil, lubricating oil and other oil products is achieved, and after the service life of the filter element is over, the thread connecting plate and the shell are separated, and the purposes that only the filter element is replaced, and the shell is repeatedly used are achieved. The oil product circular purifying device has the beneficial effects of being easy and convenient to dismount and mount and the like, and the requirement for filtering common oil products is met.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a circulating filter device for purifying oil products. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, resulting in increased fuel consumption and a sharp increase in exhaust emissions after the engine has been used for a period of time. The current general solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the fuel to make the fuel clean. Clean fuel can improve combustion efficiency, thereby saving fuel and reducing emissions; it ...

Problems solved by technology

[0006] The present invention proposes an oil circulation purification device based on a universal spin-on filter, which can be used for the filtration of fuel or non-fuel oil, realizes the cleaning of oil, and solves the problem of existing filter shells at the same time. The non-replaceable problem of the middle filter element enables the shell to be reused, and at the same time, the oil filter of the present invention is simple to replace and easy to operate
