Abstract

The utility model relates to a diesel filter for an internal-combustion engine, which is mainly composed of a filter seat, a rotational flow plate, a flow guiding cover, a filter core, an oil stabilizing tray, a casing body and a connecting cap. The utility model has the advantages of favorable filtering effect, simple manufacturing process, convenient maintenance and assembly. Because the casing body is transparent, the user can clearly observe the working condition in the filter, which is favorable to scavenge the moisture and the impurity in the casing body in time and supply purer oil for the internal-combustion engine.

Description

Diesel filter for internal-combustion engine

The diesel-oil filter that advances in the geographic coverage in the geographic coverage is mainly used in moisture content and impurity in the elimination diesel oil, is suitable for doing the tractor heart especially---the matched diesel-oil filter of internal-combustion engine.

Domestic production at present, the conventional diesel filter cleaner that uses is the iron-clad diesel-oil filter, as shown in Figure 1,

pull bar

12 and 3 riveted joints of irony housing, be inserted in holddown spring 11 on the pull bar 12 respectively, bracket 10, pallet 9, pallet 9 support filter cores 1, by stay-bolt 5 with pull bar 12, filter core 1 and housing 3 etc. in addition parts and filter block 2 link together, outside diesel oil leaks into housing, add housing seal packing ring 7 between housing 3 and the filter block 2, be provided with filter core seal washer 6 between filter core 1 and the filter block 2, pallet 9 is provided with pull bar seal washer 8, is provided with packing ring 4 between stay-bolt 5 and the filter block 2.The processing iron-clad needs through blanking, punching press, stretch, moulding, pickling, spray paint, multiple working procedures such as oven dry, the corresponding matching die and operations such as impact briquetting are still needed, the pull bar riveted joint needs through machined into, pickling, electroplate, the filter block material is the pig iron, ash content is big, impurity is many, so traditional diesel-oil filter complex manufacturing, operation is many, cleanliness is relatively poor, perishable, and pull bar and the easy leakage of oil of irony housing riveted joint place, the oil distributions was even inadequately when diesel oil entered housing 3 by filler opening, and internal combustion engine time vibrations are big, the water and the impurity that will be deposited on easily at the bottom of the shell rise, attached to the filter core outer wall, reduce the filtering function of filter core, because iron-clad is opaque, can't see profit layering and impurity deposition conditions in the housing, therefore can not in time clean filter cleaner, under best fuel feeding operating mode, work, make troubles also for simultaneously detection and maintenance to guarantee internal-combustion engine.

The purpose of this utility model will remedy above-mentioned the deficiencies in the prior art exactly, provides a kind of technology simple, and cleanliness is good, and is corrosion-resistant, and leakproof, filtering are effective, are convenient to the automotive diesel oil filter cleaner that detects, keeps in repair, cleans again.

Task of the present utility model is finished as follows, the automotive diesel oil filter cleaner comprises: the filter block, filter core and the housing that have oil inlet hole, oil outlet, its characteristics are the eddy flow plate that the below of filter block oil outlet is linked in sequence and has at least three following oilholes, air guide sleeve, filter core and steady food tray, it is cup-shaped that housing adopts transparent plastic once to be injection molded into, and attachment cap is movably connected housing and filter block.

The eddy flow plate of the utility model diesel fuel for internal combustion engines filter cleaner, air guide sleeve, steady food tray can adopt a drawing of aluminium skin.

The filter block and the attachment cap of the utility model automotive diesel oil filter cleaner can adopt aluminium diecasting.

The diesel oil that needs filtering enters cavity under the filter block by oil inlet hole, following oilhole on the eddy flow plate disperses to flow in the housing equably again, the diesel oil that air guide sleeve can be avoided having impurity and moisture directly contacts filter core, oil stream is imported lower housing portion equably, the current stabilization cover is set prevents that the dregs that are deposited on housing bottom from rising because of being given a shock, so that reduce the filtering function of filter core; It is cup-shaped that housing adopts transparent plastic once to be injection molded into, can leakproof, corrosion-resistant ， And can see profit layering and impurity deposition conditions intuitively clearly.

Advantage of the present utility model is that technology is simple, assembling, easy to maintenance, cleanliness is good, corrosion-resistant, because housing is transparent, intuitively profit layering, impurity deposition conditions, can in time remove moisture, impurity in the housing, the internal combustion function be worked under best fuel feeding operating mode, thereby prolonged machine life.

Below in conjunction with embodiment shown in the drawings the utility model is further described.

Fig. 2 is the plan view of the utility model automotive diesel oil filter cleaner.

Fig. 3 is along the sectional view of 1～1 line automotive diesel oil filter cleaner among Fig. 2.

As Fig. 2, shown in Figure 3, filter block 1 is provided with oil inlet hole 2, oil outlet 3, connects bearing 4, limit rib 5, middle rib 6, toroidal cavity 7, and filter block adopts whole aluminium diecasting.Filter block is followed successively by for 1 time and radially is evenly distributed with four following oilholes 11, air guide sleeve 13, filter core seal washer 14, filter core 15, steady oil pan packing circle 16, steady food tray 17, screw gasket 18, above-mentioned parts in addition on eddy flow plate seal washer 9, eddy flow plate 10, the plate and is fixed in the blind hole under the filter block 1 with screw 19, eddy flow plate 10, air guide sleeve 13, steady food tray 17 are aluminium skin or galvanized sheet iron stamping part, and packing ring adopts oil resistant rubber.Housing 20 adopts the PVC industrial plastic once to be injection molded into cup-shaped.Attachment cap 22 is an aluminium diecasting, and the cap inwall has the external screw thread of female thread and filter block 1 outer ring to be complementary.Put into housing seal packing ring 21 in the toroidal cavity 7 during assembling under filter block 1, the transparent cup-shaped housing 20 that closes puts attachment cap 22 and screws, and housing 20 and filter block 1 are tight connecting.

During use, the proper site that bearing 4 is fixed in internal-combustion engine will be connected, enter oil inlet hole 2, the cavity 8 of diesel-oil filter through oily joint by the next diesel oil of fuel tank, following oilhole 11 on the eddy flow plate again, oil stream is entered in the housing 20 equably, just under the lower housing portion deposition, upper strata diesel oil is delivered to combustion chambers burn through filter core 15, oil outlet 3, oily joint, transport pipe for oil air guide sleeve 13 water conservancy diversion of flowing through, water in the diesel oil and impurity.Though diesel-oil filter is worked in the environment of vibrations, owing to be provided with steady food tray 17, water that deposits and impurity are difficult for rising.When filter cleaner need clean,, unload transparent shell 20 and get final product as long as outward winding attachment cap 22.
