Abstract

The utility model relates to a spiral fitting type oil filter which belongs to an internal-combustion engine accessory and is suitable for filtering the lubricating oil and the fuel oil of internal-combustion engines of various purposes. The utility model is characterized in that a shell body is made into a straight drum shape, a filter core comprises metal nets (7) and (9) and a filter layer (8), the filter layer (8) is clamped between two metal nets, and the filter layer (8) is made of polypropylene fibre. Compared with the existing spiral fitting oil cleaner, the utility model has the advantages of simple preparing process, long service life, little resistance of liquid flow and high filter precision.

Description

Spiral fitting oil cleaner

The utility model belongs to internal combustion engine fittings, applicable to the lubricating oil of the internal combustion engine of various uses and the filtering of fuel oil.

The housing of existing rotation fitting type oil plant cleaner is a staged drum shape; processing technology is complicated; filter core is made of layer of metal catch net and filter course; the material that constitutes the filter element filtering layer is to adopt a kind of filter paper of external import; the filter paper core filter paper of domestic production does not at present reach the standard of external import, and filter paper also has cracky simultaneously, and service life is short; shortcomings such as dirty solubility is poor, and filtering precision is low.

The purpose of this utility model is that a kind of handling ease will be provided, long service life, the little and higher dress formula oil plant cleaner of filtering precision of liquid flowing resistance.

Technical essential of the present utility model is that housing is processed into straight drum shape, and filter core is provided with the double layer of metal catch net, and uses filter course instead polypropylene fiber.

Rotation fitting type oil plant cleaner of the present utility model is as shown in Figure 1: be to be skeleton with housing (6), filter core is stuck between loam cake (13) and the lower cover (14), spring (10) is housed below lower cover (14) withstands filter core, the common closure casing top of cover clamp (11) and spinning thread plate (2) is arranged above the loam cake (13), oil-in (4) and (12), oil-out (1) all are located on the spinning thread plate (2), middle with rubber seal (5) isolation, seal the contact position of internal combustion engine and cleaner topmost with sealing ring (3).Feature of the present utility model to be housing (6) be straight drum shape, filter core is that the filter course (8) by metal coating net (7) and (9) and two net sandwich thereof is constituted.

In order to prolong the service life of cleaner, the material of filter course of the present utility model (8) is to adopt the polypropylene fiber coiling to form.

Operation principle of the present utility model is: the screw thread spinning of filter assembly by revolving thread plate is on internal combustion engine, after oil plant is under pressure, be pressed in the annular compartment (15) by oil-in (4) and (12), and then, flow into internal combustion engine through oil-out (1) by after the filter core filtering.If lubricating oil is got back to the reservoir compartment after work is finished, if fuel oil then enters the internal combustion internal combustion and burns, when blocking because of the too dirty filter core of oil plant, the oil plant cleaner that just should more renew.

The utility model is than the oil plant cleaner handling ease of existing rotation fitting type, and cost is low, long service life, and liquid flowing resistance is little, the filtering precision height, and can save foreign exchange.

Description of drawings:

Fig. 1: the generalized section of rotation fitting type oil plant cleaner of the present utility model.

Among the figure: (1) oil-out, (2) spinning thread plate, (3) sealing ring, (4) oil-in, (5) sealing ring, (6) housing, (7) wire netting, (8) filter course, (9) wire netting, (10) spring, (11) cover clamp, (12) oil-in, (13) loam cake, (14) lower cover, (15) cavity.

Claims

1, a kind of rotation fitting type oil plant cleaner, be to be skeleton with housing (6), filter core is stuck between loam cake (13) and the lower cover (14), spring (10) is arranged below filter core lower cover (14), cover clamp (11) and spinning thread plate (2) are arranged above the filter core loam cake (13), oil-in and oil-out are located on the spinning thread plate (2), middle with glue sealing ring (5) isolation, feature of the present utility model to be housing (6) be straight drum shape, filter core is that the filter course (8) by wire netting (7) and (9) and two net sandwich thereof is constituted.
