Abstract

The utility model relates to a filtering cylinder of a fine filter for compounded high molecular fuel oil, which is integrally made of magnetic compounded high molecular porous hard materials. The filtering cylinder is made into a folding cylinder shape. The filtering cylinder is integrally made of compounded high molecular porous hard materials, and can be taken off for scale removing and cleaning, so the utility model has low manufacture cost, high precision, and long service life. The filtering cylinder adopts the folding cylinder structure to cause the filter area to be increased, so the filtering flow rate is large.

Description

Composite high-molecular secondary fuel oil filter filter cylinder

The utility model relates to the filter cylinder of filter core in a kind of secondary fuel oil filter.

The present secondary fuel oil filter that uses, its filter core are to add metal net and respective accessory and the double-decker that constitutes by soft filter paper or filter cloth, and there is following shortcoming in they: 1. make filtering material by filter paper or filter cloth, and its fleece hole size inequality, filtering accuracy is poor; 2. the fiber of filter paper or filter cloth is in use easily deviate from oil, and service life is short; 3. filter paper or filter cloth must be furnished with the metal net and do supporter, the manufacturing cost height; 4. filter paper or filter cloth after filtering must be changed, and can not reuse; 5. such filter core is not had a magnetic material, and short grained ferromagnetism impurity is not had a filtering function; 6. manufacturing structure complexity.

For this reason, Chinese patent CN2155441Y discloses a kind of filter cylinder of the secondary fuel oil filter filter core of making of composite high-molecular, has overcome above-mentioned defective preferably, but because the cross section of its filter cylinder is an annulus, filter area is little, so also exist the shortcoming of filtering traffic deficiency in application.

In view of above-mentioned, the utility model will provide a kind of filtering accuracy height, long service life, low cost of manufacture, filtering traffic big, after moving back dirt reusable filter cylinder.

For reaching this purpose, the utility model by the following technical solutions: a kind of composite high-molecular secondary fuel oil filter filter cylinder, it is made into integration by magnetic composite high-molecular porous hard material, it is characterized in that: this filter cylinder is the folding tubular.

Because this filter cylinder is made into integration with composite high-molecular porous hard material, can takes off and move back dirty cleaning, so low cost of manufacture, filtering accuracy height, long service life.Because this filter cylinder adopts the folding tubular construction, make filter area increase, so filtering traffic is big.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the schematic cross-section of filter cylinder;

Fig. 2 is the fine filter structure chart.

See also accompanying drawing 1, the utility model is a kind of filter cylinder 3 that is made into integration with magnetic composite high-molecular porous hard material, and filter cylinder is made the folding tubular of being joined and being formed by a plurality of semicylinders.

See also accompanying drawing 2, fine filter is made up of cover 1, rack 2, macromolecule folding cylindrical filtration cartridge 3.Wherein: cover 1 is for having the dish of central shaft hole, and its edge is short tubular; The two ends up and down of rack 2 are helicoid tubulose, and the bottom has the eyelet that fuel oil is after filtration passed through, and the bottom outer wall has identical but the tube holder 4 that opening direction is opposite of a shape and cover 1.

During installation, filter cylinder 3 is placed on the tube holder 4 of rack 2, and cover 1 is through at rack 2 and upper shield on filter cylinder 3.Fuel oil is entered in the tube by filter cylinder 3 outsides, flows out from the eyelet of rack 2 again, and the impurity in the fuel oil then invests on the outer wall of filter cylinder 3, puts in back after filter cylinder 3 can being taken off cleaning in the maintenance.

Filter cylinder 3 also can be made the folding tubular that is surrounded by other shape, for example the folding tubular of being joined and being formed by the polygonal cylinder.

Claims

1. composite high-molecular secondary fuel oil filter filter cylinder, it is made into integration by magnetic composite high-molecular porous hard material, it is characterized in that: this filter cylinder is the folding tubular.
