Description

A kind of precision type plate filter

Technical field

The utility model relates to a kind of filter, especially a kind of plate filter.

Background technology

Plate filter, is again plate oil-filter, or plate and frame type filter-press; 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.

The plate frame filter of said structure, has the advantages such as features simple structure, processing ease, operating cost be low.But still existing filtering accuracy not high, the defect that volume is larger, has limited its purposes.

Utility model content

For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is, how the precision type plate filter that a kind of filtering accuracy is higher is provided, and improves its scope of application.

In order to solve the problems of the technologies described above, in the utility model, adopt following technical scheme:

A kind of precision type plate filter, comprise the filtration housing of cuboid frame structure, in filtration housing, there are the primary filter chambers that many group filtering bodies are installed side by side, it is characterized in that, filter in housing and also there is a smart filter chamber, one end that described smart filter chamber is adjacent with primary filter chamber has an inlet being communicated with primary filter chamber liquid outlet, on smart filter chamber other end liquid outlet, Coalescence filter core is installed.

In the utility model, set up the smart filter chamber that contains Coalescence filter core; Therefore can greatly improve filtering accuracy, can lean on Coalescence filter core to filter out better the moisture containing in fluid simultaneously.Improve filtering accuracy, expanded the scope of application of plate frame filter.

As optimization, described every group of filtering bodies comprises two filters that are oppositely arranged and is sandwiched in filter cloth therebetween, two opposing sides of filter are plane, a relative side side surrounding has protruding seamed edge and makes to form between seamed edge the filter space of indent, the boss that also there is two surfaces and seamed edge flush in filter space and join with seamed edge, boss middle part has liquid pass hole, arbitrary boss side surfaces be also provided be communicated with the inner liquid pass hole of boss and the outside filter space of boss cross liquid mouth; In the filter space of two filters, be all also provided with the projection of the strips of many rows surface and seamed edge flush, described bulge clearance is arranged between two boss and two ends and seamed edge join, the protruding space of two filters and shifting to install.

After optimizing like this, when fluid is flowed through in every group of filtering bodies the filter space between two filters, need pass between filter cloth repeatedly, therefore greatly improved the service efficiency of filter cloth, improve filter effect, and then can reduce in a large number the group number of filtering bodies, reduced device volume.

Further, in every group of filtering bodies, on the surrounding seamed edge of two relative sides of filter, be that trapezoidal concavo-convex cooperation forms labyrinth seal by cross section.

Like this, can improve the sealing effectiveness between filter, avoid fluid to penetrate filtering bodies and produce the oily phenomenon of string outward, can be beneficial to improve oil liquid pressure to guarantee filter efficiency simultaneously.Meanwhile, labyrinth seal can be tightened filter cloth fixing better, guarantees that fluid forms from through mode between filter cloth in filter space mobile.

As optimization, described Coalescence filter core comprises a columnar joint, joint one end is provided with external screw thread and for spinning with smart filter chamber liquid outlet, the joint other end is connected with a metallic coil bar and weaves the metal hose forming, the outer overall winding up of metal hose is provided with the coalescence filtration layer that one deck contains glass fibre, and described coalescence filtration layer adopts metal wire from the oblique pitch of the laps in joint one end to metal hose end, backward-coiled is fixed around to joint location.

Adopt the Coalescence filter core of this structure, have simple in structure, the advantage such as it is convenient to implement, and with low cost and filter core is easy for installation.

Further, be provided with a circle boss on described joint, described external screw thread is set on the joint of boss outer end, described boss arranged outside has a circle mounting groove, is embedded with a circle upper surface and is raised in the sealing rubber ring of boss side surfaces in mounting groove.

After optimizing like this, when Coalescence filter core is installed, can realize well the sealing to liquid outlet place, avoid leaking.

In sum, the utlity model has the advantages such as filtering accuracy is high, and volume is small and exquisite, simple in structure, with low cost, expanded the scope of application of plate frame filter.
