Precision oil filter for marine engine oil

Abstract

The invention relates to the technical field of filtering equipment, and discloses a precise oil filter for marine engine oil, wherein the precise oil filter comprises a shell, a bracket is fixedly connected to the middle part of one side of the shell, and a telescopic oil cylinder is fixedly connected to the middle part of the upper end of the bracket. Through the arrangement of a detection device, when the filtering efficiency of filter paper on engine oil is reduced, supplying of the engine oil is stopped, a rotary motor is started, a support frame is driven to rotate along a flow deflector, impurities deposited on the surface of the filter paper is thrown out along the outer edge of the support frame and enter a receiving groove, and filtering is carried out again after the impuritieson the surface of the filter paper are cleaned, so that the filtering efficiency of the filter paper can be improved; after the filter paper is used for a long time, when a large number of impuritiesare attached to the surface of the filter paper, the filtering capacity of the filter paper is lost, a large number of filtered engine oil is accumulated above the filter paper, and when the oil filtering height exceeds a floating rod, the outer end of the floating rod is affected by buoyancy to rotate upwards to make a conducting strip make contact with an electric contact plate to be powered onto remind people to replace the filter paper.

Description

technical field [0001] The invention relates to the technical field of filter equipment, in particular to a precision oil filter for marine engine oil. Background technique [0002] During the long-term operation of the ship, moisture, dust and solid particle impurities will inevitably be mixed into the turbine oil due to various complicated reasons, which will accelerate the oxidation of the oil, and promote the formation of foam, fouling and sludge, causing serious emulsification of the oil , leading to oil-water separation, which reduces the performance of oil lubrication, anti-wear, heat dissipation, dispersion, cooling, etc. Therefore, precision oil filters are often used as oil cleaning equipment on ships. The oil filter is composed of a primary filter, an oil pump and a fine filter device. , where the fine filter device uses special filter paper as the filter medium, the impure oil enters the fine filter machine under the pressure of the oil pump, and passes through t...

Problems solved by technology

[0003] However, the fine filter device of the existing precision oil filter for marine engine oil still has the following deficiencies in the actual use process: first, the existing fine filter equipment has a complicated structure, and it is difficult to replace the filter paper, and the surface of the filter paper will be damaged during the process of filtering the oil. The impurities after filtration are attached, so the filter paper needs to be replaced manually after a period of use, but it is found that when the filter efficiency of the oil filter machine is low and the machine is shut down to replace the filter paper, there are often impurities attached to the surface of the filter paper and If the filtering limit of the filter paper is not reached (that is, the filtering effect is lost), replacing the filter paper at this time is not only troublesome, but also causes waste of filter paper; secondly, the oil contains steel slag left by the wear and tear between the parts of the machine during work, and these tiny Metal particles remain in the engine oil and are difficult to remove. When the oil is filtered for the second time, these metal particles will adhere to the inside of the filter layer, requiring frequent replacement of the filter element of the filter layer, resulting in a significant increase in the cost of use and maintenance of the oil filter
