Novel coalescence filter core structure

Technical Field

The utility model relates to a filter core field specifically is a novel coalescence filter core structure.

Background

In current industrial equipment, the mixed pollution of oil and water liquid is inevitable, and the damage of oil and water liquid to mechanical equipment or systems is common: the metal part is corroded by reaction with acidic substances in the oil liquid; the oil is deteriorated, including the precipitation of additives, the oxidation of the oil, the reduction of the thickness of a lubricating film and the like; ice crystals are formed in a low temperature environment, causing clogging or component seizure, etc. Coalescence-separation is a relatively common method of water removal. The existing coalescence filter element can not effectively meet the functional requirements of precise filtration and high-efficiency dehydration on the premise of low cost, and can not solve the trouble caused by mixing oil, water and liquid in equipment such as an engine.

Detailed Description

The embodiments are described in detail below with reference to the accompanying drawings

The utility model provides a novel coalescence filter core structure, includes coalescence filter bed 1, skeleton 2, 2 inboard covers of skeleton are equipped with beta structure's compound filter bed 3, and 2 outside winding superpositions of skeleton have coalescence filter bed 1, and 2 both ends of skeleton are equipped with end cover 4, 1 outside of coalescence filter bed is equipped with adsorbed layer 5. The coalescence filter layer is composed of a non-woven fabric 6, glass fiber cotton 7, a glass fiber net 8, a glass fiber filter material 9 and a non-woven fabric 6 in sequence. The non-woven fabric 6, the glass fiber cotton 7, the glass fiber net 8, the glass fiber filter material 9 and the non-woven fabric 6 are wound outside the framework in sequence to form a coalescent filter layer. The composite filter layer 3 is formed by sequentially stacking a nylon protective net 11, a non-woven fabric 6, glass fibers 10, the non-woven fabric 6 and the nylon protective net 11 in sequence, then bending by a bending machine, and then sleeving the inner side of the framework. The adsorption layer is a cotton cloth cylinder.

The working principle of the utility model is as follows:

the filter core of this structure comprises multiple different filter media, and the course of work is: three stages of filtration-coalescence-separation. Oil water liquid enters the filter element through the end cover 4, and solid particles in the oil water liquid are filtered through the composite filter layer 3 with the folding structure to finish a filtering stage task; then the oil enters the coalescence filter layer 1 through the framework, and the sequentially superposed filter materials all have the attribute of deep filtration, so that a stepped complex microporous layer is formed, an oil-water emulsification structure in oil is damaged, tiny water droplets are formed, and the tiny water droplets are gradually gathered into larger water droplets under the action of the hydrophilic-oleophobic filter material; finally, the water drops are gathered into water drops through the adsorption layer and sink into the water collecting tank under the action of gravity to achieve the effect of oil-water separation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
