Description
Technical field
The utility model relates to and is used for a kind of vacuum diatomaceous earth filter that fuel oil filters.
Background technology
In the production process of fuel oil, mechanical admixture and ash content are the important quality index of fuel oil, especially residual fuel oil is often because mechanical admixture and the undesirable problems such as the obstruction of engine filter core, abnormal combustion, acceleration equipment wearing and tearing that cause of ash content are the real problems that needs fuel oil manufacturing enterprise to solve so reduce the mechanical admixture and the ash content of fuel oil.Current fuel oil manufacturing enterprise mainly carries out simple filtration with filter cloth, filter bag etc. to fuel oil, and filter effect is difficult to guarantee that filter efficiency is low.Though the vane type diatomaceous earth filter is also brought into use in fuel oil filters, but because the feed pressure that such filter relies on peripheral pump to produce filters, when filter finishing because the reduction of feed pressure, always partial material is remained in the filter, cause the filtration cakes torrefaction degree not enough, scarfing cinder difficulty and loss are big, cause cost to increase.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of slagging-off, vacuum diatomaceous earth filter that the fuel oil loss is little be convenient to is provided.
The utility model is achieved in that and is provided with charging aperture on filter top, removes cinder notch that the bottom is provided with discharging opening, vacuum port; Distributor, filter plate, screening stream baffle plate are installed in filter, and distributor links to each other with charging aperture by pipeline, hides the stream baffle plate and is positioned at the vacuum port front side, avoids liquid to enter vacuum system.
Top at blending tank is equipped with stirring motor, and the feed pump outlet is communicated with blending tank by pipeline, and the 4th control valve, the 5th control valve are installed on pipeline; In the bottom of blending tank second control valve is installed, and is connected with the feed pump import by pipeline; Raw material enters pipeline and first control valve is installed and is connected with the feed pump import by pipeline; Filter aid loading hopper bottom is equipped with control valve, and is connected with blending tank by pipeline; Blending tank is connected with the discharge pump outlet by pipeline, and the 7th control valve is installed on its pipeline; The discharge pump import is connected with the filter discharging opening by pipeline, on its pipeline control valve is installed.The charging aperture of filter is connected with the feed pump outlet by pipeline, and the 9th control valve is installed on its pipeline; The vacuum port of filter links to each other with vavuum pump by pipeline, on its pipeline control valve is installed; Product outlet links to each other with the discharge pump outlet by pipeline, and the 8th control valve is installed on its pipeline.
Advantage of the present utility model is, the super-cell that adopts the discrete particles shape is as filter medium, mainly be for filtering medium layer be that filter cake provides hole as much as possible, and the wall that forms the hole, fuel oil is passed through in the aperture of wall thus, be trapped among the surface and raceway groove of this medium being suspended in solid impurity particle in the fuel oil, thereby make solid-liquid reach the purpose of separation.
The utility model is owing to adopted vacuum system, and filter plate pressure reduction up and down exists all the time in filter process, so filter when finishing, does not have Residual oil to exist above the filter plate, and the filter cake oil content is low, is convenient to slagging-off, and the fuel oil loss is little.
Description of drawings
Fig. 1 is an equipment connection diagram of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further by specific embodiment.
As shown in the figure, charging aperture is installed on filter 2 tops, is removed cinder notch 11, discharging opening, vacuum port are installed in the bottom; Distributor 8, filter plate 9 are installed in filter 2, hide stream baffle plate 10, distributor 8 links to each other with filter 2 charging apertures by pipeline, hides stream baffle plate 10 and is positioned at the vacuum port front side, avoids liquid to enter vacuum system; Filter plate 9 is made up of the multilayer stainless steel cloth, and stainless steel cloth is 200 orders.
Cross on the top of blending tank 1 stirring motor 5 is installed, feed pump 3 outlets are communicated with blending tank 1 by pipeline, and the 4th control valve V4, the 5th control valve V5 are installed on pipeline; The second control valve V2 is installed in the bottom of blending tank 1, and is connected with feed pump 3 imports by pipeline; Raw material enters pipeline and the first control valve V1 is installed and is connected with feed pump 3 imports by pipeline; Filter aid loading hopper 6 bottoms are equipped with control valve V3, and are connected with blending tank 1 by pipeline; Blending tank 1 is connected with discharge pump 4 outlets by pipeline, and the 7th control valve V7 is installed on its pipeline; Discharge pump 4 imports are connected with filter 2 discharging openings by pipeline, and control valve V6 is installed on its pipeline.The charging aperture of filter 2 is connected with feed pump 3 outlets by pipeline, and the 9th control valve V9 is installed on its pipeline; The vacuum port of filter 2 links to each other with vavuum pump 7 by pipeline, and the tenth control valve V10 is installed on its pipeline; Product outlet links to each other with discharge pump 4 outlets by pipeline, and the 8th control valve V8 is installed on its pipeline.
Filter journey and comprise following three steps:
One, the coating of diatom filter aid, at first open the first control valve V1, the 4th control valve V4, the 5th control valve V5, start feed pump 3 and in blending tank 1, add a certain amount of fuel oil raw material, close the first control valve V1, the 5th control valve V5 and feed pump 3, open the 3rd control valve V3 then, after filter aid loading hopper 6 adds a certain amount of super-cell, close the 3rd control valve V3, start the stirring motor 5 of blending tank 1, make fuel oil and super-cell form uniform suspension; Open the second control valve V2, the 9th control valve V9, start feed pump 3 the diatomite suspension is sent into filter 2,, make the surperficial uniform spreading of diatomite suspension at filter plate 9 by distributor 8; Open the tenth control valve V10 and vavuum pump 7, because the existence of pressure reduction, fuel oil enters the bottom of filter 2 by filter plate 9, opens the 6th control valve V6, the 7th control valve V7, start discharge pump 4, cleaner liquid returns blending tank 1 again by pipeline, and so circulation forms even, stable filter cake until the surface of hollow filter screen, the thickness of filter cake is generally 3 ~ 5 millimeters, closes the second control valve V2, the 7th control valve V7.
Two, open the first control valve V1, the 8th control valve V8, feed pump 3 is directly sent into fuel oil in the filter 2, and cleaner liquid directly passes through discharge pump 4 discharge systems as finished product.Along with the carrying out of filtering, solid impurity particle in the fuel oil stops up the hole in the diatomite wall gradually, the flow of cleaner liquid in the filter 2 is reduced gradually, when being reduced to 1/3rd left and right sides of normal discharge, close feed pump 3 and stop charging, close the first control valve V1, the 4th control valve V4, the 9th control valve V9 simultaneously, after the fuel oil above the filter plate is all filtered down, continue suction filtration 2 minutes, the oil content in the filter cake is reduced, close vavuum pump 7 and the tenth control valve V10 then.
Three, after scarfing cinder is filtered and stopped, opening, remove the filter cake on filter plate 9 surfaces with instrument except that cinder notch 11.
