The plate-and-frame type filter is characterized by also comprising an oil returning mechanism, wherein the oil returning mechanism comprises oil return holes formed in the bottom of the shell of the plate-and-frame filter, the oil return holes are connected to an oil charging end of the oil pump through an oil returning pipeline, and a switch valve is arranged on the oil returning pipeline. The plate-and-frame type filter disclosed by the utility model has the advantages that a good filtration effect is achieved and the filter bodies are convenient and rapid to install.
Description
Technical field
The utility model relates to a kind of filter, especially a kind of plate and frame filter.
Background technology
Plate filter, is again plate oil-filter; Be a kind of design such as each power plant, power station, industrial and mining enterprises, lubricating oil storehouse, tractor station, oil, chemical industry, metallurgy, national defence unit that aims at, be mainly used to filter trace water in transformer oil, turbine oil, machine oil, diesel oil, hydraulic air wet goods oil and the filter plant of impurity.
The structure of plate filter is generally by filter bed, and the elements such as oil pump and coarse filter form.Wherein, filter bed comprises that one is filtered housing and is set up in parallel the many groups filtering bodies in filter housing fluid chamber, filtering bodies comprises filter, the filter frame of coupling, between filter plate and filter frame, be lined with filter paper or filter cloth as filter medium, rely on again the pressure of hold down gag by filter plate and an independent filter chamber of the fixing formation of filter frame, be pressed in filter paper or filter cloth filtration between filter plate and filter frame.For example China's utility model application number 201220148851.7 disclosed a kind of pressure type plate oil-filters are above-mentioned this version.There is the advantages such as features simple structure, processing ease, operating cost be low.
But existing plate filter, filtering bodies is generally and is directly installed on housing cavity bottom.Owing to being often difficult to realize perfectly sealing between the filter plate of filtering bodies and filter frame, therefore the fluid between filter plate and filter frame can be exuded to housing cavity bottom under pressure, like this, filtering bodies bottom is dipped in the fluid of housing cavity bottom, form like this easy access of fluid, be that the fluid that the filtering bodies of porch is oozed out directly enters in the filtering bodies in exit from external channel, affected greatly filter quality, reduced filter effect., when existing filtering bodies is installed, position by filtering chamber's inner chamber side meanwhile, exist inconvenient defect is installed.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is how to provide a kind of and can improve filter effect and filtering bodies plate and frame filter quick and easy for installation.
In order to solve the problems of the technologies described above, in the utility model, adopt following technical scheme:
A kind of plate and frame filter, comprise base plate, be fixed on the support on base plate, be fixed on the plate filter of support top, be fixed on motor and oil pump on the base plate of support below, oil pump oil outlet end is connected with plate filter oil-in by oil pipe, in the housing cavity of plate filter, be set side by side with many groups by the filter mating, the filtering bodies that filter frame and interior filter cloth thereof form, it is characterized in that, also comprise oil return mechanism, described oil return mechanism comprises the spill port of the housing bottom that is positioned at plate filter, described spill port is connected to the oil inlet end of described oil pump by oil returning tube, on described oil returning tube, be provided with switch valve.
In the utility model, owing to being provided with oil return mechanism, in the time that filter uses certain hour to change filter cloth, if find that housing cavity inner bottom part has long-pending oil, open switch valve fluid is led and got back to oil pump oil inlet end, avoided like this filtering bodies to be immersed in fluid and then the defect that causes filtering accuracy to reduce.
As optimization, the housing bottom surrounding of described plate filter is also provided with a circle oil trap, and described spill port is positioned at oil trap.The fluid that can collect better seepage like this carries out oil return.
As optimization, also comprise two columniform support bars that are horizontally set in housing cavity, in described filtering bodies, filter and filter frame both sides respectively stretch out and are provided with a journal stirrup, and described journal stirrup lower surface is provided with a deep-slotted chip breaker and coordinates and be arranged on two columniform support bars by deep-slotted chip breaker.
After optimizing like this, adopt deep-slotted chip breaker and cylindrical support bar to coordinate and install, there is filter quick and easy for installation, the mobile very advantage of convenient and smooth.
Further, described filtering bodies bottom and housing cavity bottom are for leaving the vacant state of distance.Filtering bodies is arranged on two support bars by journal stirrup suspension type.Like this, can avoid filtering bodies lower surface to contact with the fluid of bottom in housing cavity, avoid filter effect to be affected.
As optimizing, filter and filter frame one side journal stirrup entirety are triangular in shape, and opposite side journal stirrup entirety is annular.Like this, when installation, can make it that contraposition accurate quick is installed by the difformity of journal stirrup, further improve installation rate.
In sum, the utlity model has good filtration effect and filtering bodies advantage quick and easy for installation.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model while specifically implementing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In this detailed description of the invention, as shown in Figure 1, a kind of plate and frame filter, comprise base plate 1, be fixed on the support 2 on base plate 1, be fixed on the plate filter 3 of support 2 tops, be fixed on motor 4 and oil pump 5 on support 2 below base plates, oil pump 5 oil outlet ends are connected with plate filter 3 oil-ins by oil pipe, in the housing cavity of plate filter 3, be set side by side with many groups by the filter mating, the filtering bodies 6 that filter frame and interior filter cloth thereof form, also comprise oil return mechanism, described oil return mechanism comprises the spill port of the housing bottom that is positioned at plate filter, described spill port is connected to the oil inlet end of described oil pump 5 by oil returning tube 7, on described oil returning tube, be provided with switch valve 8.The housing bottom surrounding of described plate filter is also provided with a circle oil trap 9, and described spill port is positioned at oil trap 9.Also comprise two columniform support bars 10 that are horizontally set in housing cavity, in described filtering bodies, filter and filter frame both sides respectively stretch out and are provided with a journal stirrup 11, and described journal stirrup 11 lower surfaces are provided with a deep-slotted chip breaker and coordinate and be arranged on two columniform support bars 10 by deep-slotted chip breaker.Described filtering bodies 6 bottoms and housing cavity bottom are for leaving the vacant state of distance.Filter and filter frame one side journal stirrup entirety are triangular in shape, and opposite side journal stirrup entirety is annular.When concrete enforcement, base plate 1 bottom is also provided with roller 12, makes it easy to mobile.
