Description
Technical field
The utility model is related to a kind of devices for the sealing of leaf filter plate layer.
Background technology
In the aluminium sheet strip and foil operation of rolling, friction is generated between aluminium foil and roll, a large amount of aluminium powder is generated, causes to roll glossy black
Change, easily causes Foil pinhole and annealing hickie.Simultaneously because the temperature generated when oil product is rolled, pressure change, while by
The influence of air humidity, light irradiation etc., easily generates organic acid, alcohol isopolarity substance, metal soap, resinite, asphalitine, oil
The impurity such as mud, aluminium powder.Due to the presence of these Solid separates and oil soluble impurity, make ROLLING OIL film forming and bearing capacity,
Lubrication heat-sinking capability, oxidation resistance are destroyed.It is difficult to roll out the strip foil product of high quality.So high quality, high-precision
The filtration system of degree just becomes the necessary component of modernization Aluminum sheets foil mill.
Existing leaf filter layer structure is as shown in Fig. 2, by super-cell between each two plate layer filter box（It crosses
Filter medium）It is partitioned into absolute oil chamber and sump oil chamber with the filter paper of screen support.In filter paper（Non-woven fabrics）Drainage is deposited above
Dosage form is at filter layer.It is mainly used for completing the processes such as precoating, normal filtration, the purging of filtering technique, is the pass of plate filter
Key member.Rose Box is equipped with dirty oil-in, absolute oil outlet, filter cake drying（Air purges）, four interfaces such as negative-pressure sealing, by
There is certain pressure when dirty oil pocket is in filtering, and with the increase of filtration time（The thickening of super-cell）, pressure is not
It is disconnected to increase（4bar can be arrived when maximum）.Thus inevitably cause to have the ROLLING OIL of dirty oil pocket to be leaked toward negative-pressure dense sealing groove,
In order not to make ROLLING OIL leak out to the outside of plate layer and reach better seal effect, traditional method is generated by diaphragm pump
Negative-pressure sealing reaches sealing effect and takes the ROLLING OIL of leakage away.Since the diaphragm pump of high suction is at high price, diaphragm pump is
Achieve the purpose that suction, reversing valve core are moved back and forth, easily worn for 24 hours using reversing principle, spare parts cost is high, and can not
Suction capactity, poor universality are adjusted according to the filter of different plate layer numbers and pile number.Therefore need a kind of versatility it is high, at
This low efficient apparatus realizes the excellent sealing between plate layer.
Utility model content
The purpose of this utility model, is to provide for a kind of device for the sealing of leaf filter plate layer, and compressed air is logical
Filter, pressure reducing valve, the throttle valve crossed in the device obtain the power input of clean goal pressure and flow later, make injection
Device under the action of compressed air pump orifice connection plate layer negative-pressure dense sealing groove in form negative pressure, make leaf filter plate layer it
Between reach better seal effect under atmospheric pressure, while injector is taken out the ROLLING OIL in negative-pressure dense sealing groove is leaked
It sucks back in dirty fuel tank.The compressed air of different pressures and flow is realized by adjusting pressure reducing valve and throttle valve, to realization pair
Good sealing effect between various difference panel bed filter plate layers.
The utility model is realized in this way it is described it is a kind of for leaf filter plate layer sealing device, it by ball valve,
Filter, pressure reducing valve, two four-way electromagnetic reversing valves, throttle valves are linked in sequence through steel pipe, then access injector by hose
Compressed air inlet is connected sprayer pumps mouth and leaf filter plate layer negative-pressure dense sealing groove by hose and steel pipe, spray
The jet exit of emitter is connect by steel pipe with dirty fuel tank.
The operation principle of the utility model is to generate negative pressure by an injector using compressed air, make board-like mistake
Reach better seal effect between filter plate layer, while the ROLLING OIL of leakage being aspirated back in dirty fuel tank.It first will compression sky
After gas is by ball valve, filter, pressure reducing valve, reversal valve, throttle valve, it is allowed to adjust to suitable flow and pressure and enters injection
The entrance of device.Injector forms negative pressure under the action of compressed air in the plate layer negative-pressure dense sealing groove of pump orifice connection, makes plate
Reach better seal effect between formula filter plate layer under atmospheric pressure, while injector will be leaked in negative-pressure sealing
ROLLING OIL in slot is aspirated back in dirty fuel tank.
The utility model has the beneficial effects that operating personnel according to the difference of leaf filter plate layer number and can want
Reach great negative-pressure sealing to adjust the size of injector inlet compression air pressure and flow, realizes to various different plate layers
Good sealing effect between filter plate layer.
