Abstract
The utility model relates to an electric heating twin-core diesel filter which is composed of an upper cover, a cupped shell, an inner filter element, an outer filter element, a spring and sealing gasket portions. The inner filter element installed at the center of the upper cover is communicated with an oil outlet orifice, an oil inlet orifice and the outer filter element are communicated with the space of the cupped shell, the inner filter element and the outer filter element are sleeved together for using, and the contact faces of the inner and outer filter elements with the upper cover are provided with sealing gaskets. The electric heating twin-core diesel filter is characterized in that a plurality of electric-heat wire coils are wound around the surface of the outer filter element to heat the diesel inside the cupped shell, the bottom portion of the cupped shell is equipped with a drain valve which is hollow, the hollow portion of the drain valve is sealed by insulation materials after leads penetrating through an orifice, and the leads inside the cupped shell are connected with the electric-heat wire coils wound around the outer filter element. The bottom portion of the drain valve is equipped with nuts to guarantee well sealing without oil leakage, and the spring is installed between the outer filter element and the drain valve. The electric heating twin-core diesel filter has high filtering efficiency, can effectively prevent the diesel from condensing due to the cold weather, and can effectively prolong the service life of diesel engines.
Description
Technical field
A kind of electric heating twin-core diesel-oil filter belongs to the diesel oil filtration device.
Technical background
At present, diesel-oil filter with heating function is less, because cold weather when using in the winter time, diesel oil condenses easily, brought very big trouble for normal the use,, can not use filter cleaner again though there is the heating oil pipe on vehicle, to use, cause damage for easily the precision pair of diesel engine, brought the certain economic loss to the user.
Summary of the invention
At above-mentioned reason, the utility model has designed a kind of electric heating twin-core diesel-oil filter, its objective is, both can heat diesel oil, can guarantee the filtering effect again, thereby reduce inconvenience and the more effective filtration diesel oil that brings because of condensing of diesel oil, reduce the damage of diesel engine.
Its objective is such realization, design a kind of electric heating twin-core diesel-oil filter, it is by loam cake, the cup shell, inner filter core, outer filter core, spring, gasket portion is grouped into, on be covered with oil inlet hole and oil outlet, center and oil outlet that inner filter core is installed in loam cake communicate, oil inlet hole and outer filter core communicate with the space of cup shell, inner filter core and outer filter core suit use, the surface of contact of inner filter core and outer filter core and loam cake is provided with sealing gasket, the surface of filter core outside, be wound with some circle electric heating wire, be used for diesel oil in the heating cup shell, in cup shell bottom blowdown valve is housed, blowdown valve is an open-core type, has lead to pass the hollow position of back with insulating material casting sealing blowdown valve from the hole, and the lead in the cup shell is connected with the electric heating wire on outer filter core, between blowdown valve and cup shell, be provided with sealing gasket between cup shell and loam cake, the bottom of blowdown valve is equipped with nut and is guaranteed that sealing is oil-proof.Between filter core and blowdown valve spring is housed outside, is used for guaranteeing the sealing of sealing gasket between outer filter core and loam cake.
Owing to adopted such scheme, electric heating twin-core diesel-oil filter has the filtering efficiency height, can effectively stop the diesel oil that causes because of cold weather to condense, and has reduced the fault of condensing and occurring because of diesel oil, the more effective life-span that prolongs diesel engine.
Description of drawings
Accompanying drawing is the sectional structure schematic representation of electric heating twin-core diesel-oil filter.
Among the figure: 1 loam cake, 2 glasss of shells, 3 inner filter cores, 4 outer filter cores, 5 sealing gaskets, 6 blowdown valves, 7 electric heating wire, 8 springs, 9 nuts, 10 leads, 11 insulating material, 12 oil inlet holes, 13 oil outlets.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described
Referring to accompanying drawing, electric heating twin-core diesel-oil filter, it is by loam cake 1, cup shell 2, inner filter core 3, outer filter core 4, spring 8, sealing gasket 5 parts are formed, loam cake 1 is provided with oil inlet hole 12 and oil outlet 13, center and oil outlet 13 that inner filter core 3 is installed in loam cake 1 communicate, oil inlet hole 12 and outer filter core 4 communicate with the space of cup shell 2, inner filter core 3 and outer filter core 4 suits use, inner filter core 3 and outer filter core 4 are provided with sealing gasket 5 with the surface of contact of loam cake 1, the surface of filter core 4 outside, be wound with some circle electric heating wire 7, be used for diesel oil in the heating cup shell 2, in cup shell 2 bottoms blowdown valve 6 is housed, blowdown valve 6 is an open-core type, has lead 10 to pass the hollow position of back with insulating material 11 casting sealing blowdown valves 6 from the hole, and the lead 10 in the cup shell 2 is connected with the electric heating wire 7 on outer filter core 4, at blowdown valve 6 and 2 on shell of cup, cup shell 2 and 1 of loam cake are provided with sealing gasket 5, and the bottom of blowdown valve 6 is equipped with nut 9 and is guaranteed that sealing is oil-proof.6 of filter core 4 and blowdown valves are equipped with spring 8 outside, are used for guaranteeing the sealing of outer filter core 4 and 1 sealing gasket 5 of loam cake.
In use, the lead 10 that passes blowdown valve 6 centers is joined with power supply, electric heating wire 7 energising back heatings, thereby the diesel oil that heating cup shell 2 and outer filter core are 4, diesel oil after the heating is through the filtration of outer filter core 4 and inner filter core 3, supply with the oil supply system of diesel engine by oil outlet 13, thus the effect of having played heating diesel oil, having filtered diesel oil.
