The diesel fuel filter device has the beneficial effects that the height of the oil outlet and an input of an oil pump are consistent, thereby reducing the pressure loss, and increasing the discharge capacity of diesel fuel.
Description
(1) technical field
The utility model relates to a kind of filtering device for diesel, particularly a kind of inner product formula diesel fuel filter.
(2) background technique
At present, generally the Diesel oil filter of Cai Yonging mainly is the outer inner product formula oil suction filter of case, this filter is connected pattern with pipeline be screwed connection, suspension type is installed, its oil inlet and outlet is positioned at the upper end of inner product formula oil pocket, oil pockets such as need are filled the back oil outlet just can have filter oil to flow out, and this structural type gathers greasy dirt easily, not easy cleaning and discharge; Dismounting is cumbersome when cleaning filter cylinder, and the whole chamber of waste diesel oil.Also have, suspension type is installed to the pipeline boost pressure, is unfavorable for the installation and maintenance of pipeline.
(3) summary of the invention
The utility model provides a kind of inner product formula diesel fuel filter easy to install in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of inner product formula diesel fuel filter, comprise housing, filler opening, oil outlet, the filtrating equipment between filler opening and oil outlet, it is characterized in that: described housing is fixed on the bearing, and the below of housing is provided with sewage draining exit and the sewage draining exit pipe plug corresponding with sewage draining exit.
The more excellent technological scheme of the utility model is: described filler opening, oil outlet and housing are flange-type structure.
Described filtrating equipment comprises filter cylinder and filter screen, and filter cylinder is provided with axial four rows, the uniform towards periphery elongated hole in footpath, is provided with between every round and ties up groove, ties up and is provided with the copper cash of tying up filter screen in the groove.
Described filtrating equipment is a substantially horizontal, and described filter cylinder one end is provided with the filter cylinder flange; One end of filtrating equipment is connected with housing by the filter cylinder flange, and the other end is by being used for avoiding the steel plate of the direct impact filtration device of Diesel oil to support.Described bearing adopts lower margin formula structure.
Because small-sized thermal power plant oil ignition system pipeline generally is higher than about terrace 500mm, oil outlet is consistent with the oil pump entrance height, for reducing the pressure loss, increases the passing capacity of diesel oil, diesel fuel filter has been carried out improving design, and technological points of the present utility model is as follows:
1. improve the cartridge structure form, made passing capacity increase.The diesel fuel filter filter cylinder all adopts the form of uniform circular hole at present, and the utility model adopts axial 4 rows, and the mode of radial equipartition elongated hole adds filter screen, and copper cash is tied up.(60 orders/in), nominal flow rate reaches 10m to bring up to 250 μ m at filter precision
3/ h, and its inlet and outlet pressure loss only is 0.1MPa.
2. improved the bind mode of filter cylinder and housing, made filter cylinder more firm.Inner product formula oil suction Filter cartridge all adopts the supending roll type structure at present, and filter cylinder and housing pass through spiral marking connection.The utility model filter cylinder adopts the mode of two end supports, and an end and housing adopt flange coupling, and the other end adopts an arc plate to be supported in inner walls.
3. the utility model adopts and to set up the formula baffle plate at the filler opening place, effectively stoped newly to advance diesel oil and directly impact filter cylinder, has also avoided mixing of diesel oil and sump oil simultaneously, increased filter capacity, has prolonged the working life of filter cylinder, filter screen.
4. lower housing portion is provided with sewage draining exit, but the periodic cleaning dirt.
5. the housing two ends are provided with flange, convenient installation connection and cleaning, replacing filter cylinder.
6. oil inlet and outlet is flange-type structure, and convenient and pipeline connection makes this filter can be installed in any part of fuel transfer system pipeline.
7. lower margin formula bearing is adjusted highly according to actual needs, is easily installed on floor or the supporting frame.
Oil outlet of the present utility model is consistent with the oil pump entrance height, has reduced the pressure loss, has increased the passing capacity of Diesel oil.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that master of the present utility model looks schematic representation;
Fig. 2 is a schematic top plan view of the present utility model;
Fig. 3 is that schematic representation is looked on a left side of the present utility model;
Fig. 4 is the structural representation of the utility model filtrating equipment;
Fig. 5 is that the utility model filter A-A shown in Figure 4 is to schematic representation.
Among the figure: 1 filler opening, 2 oil outlets, 3 housings, 4 filter cylinder flanges, 5 sewage draining exit pipe plugs, 6 bearings, 7 steel plates, 8 cartridge filters, 9 copper cash, 10 filter screens.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises housing 3, filler opening 1, oil outlet 2, the filtrating equipment between filler opening 1 and oil outlet 2, and housing 3 is fixed on the lower margin formula bearing 6, and the below of housing 3 is provided with sewage draining exit and the sewage draining exit pipe plug 5 corresponding with sewage draining exit; Filler opening 1, oil outlet 2 and housing 3 are flange-type structure; Filtrating equipment comprises cartridge filter 8 and filter screen 10, and cartridge filter 8 is provided with axial 4 rows, and the elongated hole that the footpath is uniform towards periphery is provided with between every round and ties up groove, ties up and is provided with the copper cash 9 of tying up filter screen in the groove; Filtrating equipment is a substantially horizontal, and an end of filtrating equipment is connected with housing 3 by filter cylinder 8, and the other end is by being used for avoiding the steel plate 7 of the direct impact filtration device of diesel oil to support; Steel plate 7 has effectively stoped and has newly advanced the direct impact filtration tube 8 of diesel oil, has also avoided mixing of diesel oil and sump oil simultaneously, increased filter capacity, has prolonged the working life of filter cylinder, filter screen.The filter precision of filter screen 10 is that (60 orders/in), taken into account the purpose of protection oil pump and raising passing capacity, nominal flow rate reaches 10m to 250 μ m
3/ h, and its inlet and outlet pressure loss only is 0.1MPa.
Diesel oil enters housing by filler opening 1, because the suction of pump, oil product directly impacts steel plate 7 back break-ins, charge into filtrating equipment housing 3 on every side, rising along with liquid level in the housing 3, filtrating equipment is started working, and diesel oil enters the filter cylinder inner chamber by filter screen 10, enters pipeline by the pipeline pressure effect through oil outlet 2.The dirty assorted dirt of diesel oil is isolated in outside the filter screen 10, is deposited in gradually in the housing of filter cylinder bottom, steel plate 7 has stoped diesel oil directly to impact filter cylinder, has cut off mixing of diesel oil and sump oil, can regularly open sewage draining exit pipe plug 5, discharges sump oil.
When filtrating equipment need clean, open sewage draining exit pipe plug 5 earlier, discharge oil product and dirt in the housing 3, open the connection fastening piece on the shell flange then, shift out filtrating equipment, take copper cash 9 apart, peel filter screen 10 and clean or change, the inner chamber to filter cylinder and housing 3 cleans then.
