Abstract
The present invention relates to a kind of filter, more particularly to a kind of double-drum filter that can mutually switch, present invention solves the technical problem that being：How the double-drum filter safeguarded to filter in the case where hydraulic system is not stopped.A kind of double-drum filter that can mutually switch, including the first filter, the reversal valve of first and second filter of the second filter and connection that are connected by pipeline, oil inlet and oil-out are respectively equipped with the middle of upper and lower two pipelines, reversal valve is made up of oil-feed reversal valve and fuel-displaced reversal valve, oil-feed reversal valve and fuel-displaced reversal valve are attachment structure in the same direction, and oil-feed reversal valve and fuel-displaced reversal valve are respectively arranged at the oil inlet and oil-out；The side wall of the first filter and the second filter is equipped with purge cock, and top is provided with observation panel.Advantage is：Not only moisture content and solid impurity can simultaneously have been filtered but also vacuum dewatering plant can have been shielded when that need not be dehydrated and contaminant filter had been used alone.
Description
Technical field
The invention is related to a kind of filter, more particularly to a kind of double-drum filter that can mutually switch.
Background technology
Fluid in various kinds of equipment is mainly used in lubricating and cools down, but system element abrasion in use can produce metal powder
End and seal can produce rubber impurities.These metal dusts and rubber impurities are mixed into fluid so that the lubrication of fluid and cold
But effect reduction, therefore fluid needs constantly to be filtered during recycling.But many equipment need long-term continuous
Work, therefore corresponding hydraulic system is also required to long continuous operation therewith, after filter uses a period of time in hydraulic system
Filter core in filter can be blocked by various impurity, therefore be accomplished by entering the filter core in filter according to the situation of plugged filter
Row is changed or cleaned.Filter common at present is that filter core that cannot be to filter in the case of non-stop-machine is changed.
The content of the invention
It is an object of the invention to provide a kind of bitubular that can be safeguarded to filter in the case where hydraulic system is not stopped
Filter.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of double-drum filter that can mutually switch, including the first filter, the second filter and the connection connected by pipeline
The reversal valve of first and second filter, first filter and the second filter are connected by upper and lower two pipelines,
Oil inlet and oil-out are respectively equipped with the middle of upper and lower two management, the reversal valve is by oil-feed reversal valve and fuel-displaced commutation valve group
Into the oil-feed reversal valve and fuel-displaced reversal valve are attachment structure in the same direction, and the oil-feed reversal valve and fuel-displaced reversal valve are respectively mounted
At the oil inlet and oil-out；The side wall of first filter and the second filter is equipped with purge cock, states the first mistake
Filter and the second filter are provided with observation panel.The double-drum filter is connected in hydraulic system, and fluid enters from oil inlet
Filter, the first or second filter is entered by oil-feed reversal valve, and fuel-displaced reversal valve from oil-out is passed through by the fluid for filtering
Flow out the double-drum filter.Observe that the filter core in filter is blocked up by impurity by observation panel after the filter is using a period of time
Plug, the pressure rise of oil inlet illustrates to need to change the filter core in filter.Operation reversal valve oil-feed reversal valve and fuel-displaced change
Act the switching for realizing first and second filter simultaneously to valve, fluid is filtered into another filter, now can not shadow
The previously used remaining oil in filter the inside is released by purge cock in the case of ringing hydraulic work system, and filter core is entered
Row is changed.
Further, also including connecting the by-passing valve of the pipeline of the oil inlet and oil-out both sides respectively.In operation reversal valve
Avoid influenceing the normal work needs of hydraulic system to connect other respectively in the pipeline of oil inlet and oil-out both sides during switch filtering device
Port valve, by-passing valve is first opened before switching, and by-passing valve is turned off after the completion of switching.
Further, the warning device also including the pressure sensor at oil inlet and reception pressure sensor signal.For
Prevent filter core from blocking and damage filter, pressure sensor is set in the oil inlet of the double-drum filter, when pressure value reaches alarm
Device setting value Times alarm device warning reminding user changes filter core.
Further, the reversal valve is four-way valve.
Further, the oil inlet is located at the top of pipeline, and oil-out is located at the bottom of pipeline.
Further, it is fixedly connected by ring flange between the reversal valve and the first filter, the second filter.
The present invention compared with prior art, has the following technical effect that：1st, the feelings of hydraulic system normal work can not influenceed
Filter element is changed under condition；2nd, the pressure of filter oil inlet can be monitored, improves the peace of the double-cartridge filter
Quan Xing；3rd, simple structure, low cost of manufacture.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the double-drum filter that can mutually switch in a kind of filter process, including the first filtering connected by pipeline
The reversal valve 3 of device 1, the second filter 2 and connection first and second filter 1,2, first filter 1 and second
Filter 2 is connected by upper and lower two pipelines 4,5, and oil inlet 6 and oil-out are respectively equipped with the middle of upper and lower two pipelines
7, the reversal valve 3 is made up of oil-feed reversal valve 31 and fuel-displaced reversal valve 32, the oil-feed reversal valve 31 and fuel-displaced reversal valve
32 is attachment structure in the same direction, and the oil-feed reversal valve 31 and fuel-displaced reversal valve 32 are respectively arranged in the oil inlet 6 and fuel-displaced
At mouth 7.The double-drum filter is connected in hydraulic system, and fluid enters filter from oil inlet 6, by oil-feed reversal valve
31 enter the first filter 1 or the second filter 2, are flowed out from oil-out 7 by fuel-displaced reversal valve 32 by the fluid for filtering
The double-drum filter.Observe that the filter core in filter is miscellaneous by observation panel 11,21 after the filter is using a period of time
Matter is blocked, the pressure rise of oil inlet 6, illustrates to need to change the filter core in filter.Operation reversal valve 3 and oil-feed commutation
Valve 31 and fuel-displaced reversal valve 32 act the switching for realizing first and second filter 1,2 simultaneously, and fluid enters another filter
Filtered, the previously used remaining oil in filter the inside is passed through to put in the case of can not now influenceing hydraulic work system
Whelk plug 12,22 is released, and filter core is changed.
Avoiding influenceing the normal work of hydraulic system when 3 switch filtering device of reversal valve is operated needs in oil inlet 6 and oil-out 7
Connecting bypass valve 8 is distinguished in the pipeline of both sides, by-passing valve 8 is first opened before switching, by-passing valve 8 is turned off after the completion of switching.
Filter is damaged in order to prevent filter core from blocking, pressure sensor 9 is set in the oil inlet 6 of the double-drum filter, work as pressure
Value reaches the setting value Times alarm device warning reminding user of warning device 10 and changes filter core.
