Abstract

The utility model relates to a diesel oil purifier with internal type heating rod. Various diesel oil prefilters which are sold on the market at present can not generate problems when the prefilters are used under normal climate, however, the diesel oil can generate wax deposition phenomena easily when seasons change or the prefilters are used in a plurality of cold zones, thereby causing unsmooth filtration and even clogging to cause unavailable normal work of engines. The utility model aims at developing a diesel oil purifier with internal type heating rod. The structure comprises a shell and an upper cover which are sealed through a packing washer to form an outer shell of the diesel oil purifier, a filter element and a heating rod are fixed in the outer shell of the purifier, the heating rod is arranged into an internal structure, and thereby a complete diesel oil purifier with internal type heating rod is formed. The oil purifier can achieve the purposes that a diesel oil purifier has simple structure, convenient use and installation and clean filtration, and is adapted to being used under bad weather of cold areas in China. The space can be effectively utilized, and the heating functions can be increased under the condition that the volume of an original device is not changed.

Description

Inbuilt heating rod diesel oil purifier

One, technical field

The utility model relates to the liquid fuel filtration art, especially relates to a kind of inbuilt heating rod diesel oil purifier.

Two, background technique

Impurity such as the residual to some extent colloid of meeting, asphalitine, ashes, metal fragment in present production, transportation, the storage process at diesel oil itself, when causing diesel oil to use, because atomizing effect is poor, burning back emission smoke intensity value is higher, cause atmospheric pollution easily, when wasting energy, diesel engine is also caused damage to a certain extent.In the prior art field, exist some to adopt filtration gauze type, that carry out simple coarse filtration on the market, it in fact just utilizes gauze, diesel oil prefilter, and the solid impurity big slightly to some particle diameter stops simply, can not clean filtration effectively to diesel oil.The various filtering device for diesel of selling on these markets all use the problem that do not have under general weather, but at seasonal variations or some cold areas, diesel oil is prone to the wax deposition phenomenon and takes place to filter smooth even stop up, and causes the diesel engine can't proper functioning.

Three, technology contents

The utility model is developed a kind of inbuilt heating rod diesel oil purifier at above-mentioned deficiency of the prior art.Reach that diesel oil purifier is simple in structure, easy to install and use, cleaning is filtered, constancy of volume, adapts to the purpose that China's cold area severse weather uses down.

For solving the problems of the technologies described above, the technical solution of the utility model is:

Inbuilt heating rod diesel oil purifier, form the diesel oil purifier frame by housing and loam cake by the seal ring sealing, it is characterized in that: at this purifier frame internal fixation filter core, in the filter core inner chamber body heating stick is installed, forms a built-in diesel oil purifier of complete heating stick; Sealing and fixing filter core on the filter cartridge seat of housing lower end fixedly has the heating bolt of heating stick on the screw of filter cartridge seat, heating stick upper end screw and on the bolt that covers be connected to form independently positioning screw; Filter core upper end and loam cake sealing and fixing, a side diesel oil import communicates with the inner walls cavity above the loam cake, and the filter core inner chamber in the housing communicates with the outlet of loam cake diesel oil.

Adopt the utility model inbuilt heating rod diesel oil purifier, have the following advantages and effect:

1, inbuilt heating rod diesel oil purifier, simple and reasonable, make heating stick be arranged to built-in structure according to different diesel oil purifiers, easy for installation; Solved the effectively problem of clean boot and proper functioning of cold area diesel engine.

2, for the built-in structure of heating stick, heating stick and bolt have connected as one triple functions, not only make heating stick be positioned with heating function, replaced the effect of an original bolt location filter core simultaneously, the 3rd, have the function that positioning housing and loam cake connect as one.Effectively utilized the filter core internal space,, increased heating function not changing under original diesel oil purifier volume situation.

3, filter precision height can play good filtering effect to diameter at impurity more than 15 microns etc.; The filter efficiency height, the filter efficiency of this filtrating equipment can reach more than 90%.

4, range of flow is bigger, and the flow that filters back diesel oil can reach about 100 liters of per minutes.

5, structure-integrated, external form is light and handy and easy to use, the mounting point is flexible, and housing is that material adopts the extrusion process once-through with the aluminum alloy, thereby can additionally not increase metal impurities.

6, water environment capacity is strong, and has higher drainage function.

7, have the pressure deixis, can in time remind the user that filter core is changed, guarantee that pre-filtrating equipment can continue proper functioning.

Four, description of drawings

Fig. 1 is the built-in structural representation of the utility model heating stick.

Above-mentioned number in the figure is described as follows:

The 1-loam cake, the 2-bleeder screw, the 3-bolt, the import of 4-diesel oil, the 5-sewage draining exit, 6-heats bolt, 7-filter core, 8-housing, 9-seal ring, the outlet of 10-diesel oil, 11-heating stick, 12-filter cartridge seat.

Five, embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.Referring to Fig. 1, form automobile-used formula diesel oil purifier frame by housing 8 and loam cake 1 by seal ring 9 sealings, at this diesel oil purifier frame internal fixation filter core 7, heating stick 11 is installed in filter core 7 inner chamber body forms the built-in diesel oil purifier of complete heating stick.Specifically, two same housings 8 are arranged, with one is the example explanation, sealing assembling filter core 7 on the housing 8 lower end filter cartridge seat 12, the heating bolt 6 that fixedly has heating stick 11 on the screw of filter cartridge seat 12, bolt 3 on heating stick 11 upper end screws and the loam cake 1 is connected to form an independently positioning screw, and this is one of structural feature.This positioning screw plays three and each and every one acts on, and the one, location heating stick 11, two, location filter core 7, three, positioning housing 8 is connected with loam cake 1.Originally the common screw of location filter core 7 is replaced by this positioning screw.Filter core 7 upper ends and loam cake 1 sealing and fixing, filter core 7 upper and lower end are fixed like this, and the center is by this positioning screw location.Two same housings 8 are tightly connected below the loam cake 1, loam cake 1 upper right diesel oil import 4 communicates with the 8 inwall cavity parallel connections of two housings, diesel oil enters into its inner chamber by filter core 7 thus, through filtering and heating, according to different situations, the diesel oil heating controls to suitable temperature, as is controlled between 10-40 ℃.Diesel oil after filtration and the heating is up under pressure by loam cake 1 diesel oil outlet 10 outputs.Bleeder screw 2 is arranged above the loam cake 1, and bleeder screw 2 following exhaust ports lead in the housing 8, and housing 8 lower ends one side has sewage draining exit 5, by handle control, regularly a blowdown or a blowdown at any time.

Need to prove: no matter be one, still a plurality of filter cores 7 all can assemble a heating stick 11 at the center bore of each filter core 7, are called the built-in structure of heating stick, and this is two of a structural feature.The surface temperature control of heating stick 11 makes the diesel oil through flowing after the filtration here be heated to suitable temperature at 185-210 ℃, generally can be controlled between 10-40 ℃, also can adjust according to different situations certainly.
