Description
Technical field
The utility model relates to a kind of filter core mounting structure of filter.
Background technology
At present, filter core is mainly passed orifice plate by the filter core mounting structure of pneumatic filter, by spring sealed joint, one end of filter core is fixed on pressing plate, pressing plate is connected with orifice plate by bolt, bolt is also provided with distance sink tube, the joint of filter core and be equipped with seal washer between filter core and the gap of orifice plate.The applicant is found in the process of being installed filter core by said structure, existing filter core mounting structure component part is many, install more complicated, the spring sealed joint used easily lost efficacy on the one hand in use for some time, in filter core back blowing process, spring seal nipple limits blowback air and enters filter core on the other hand, have impact on the effect of follow-up filter core blowback, simultaneously above-mentioned seal washer is also easily damaged, very easily causes filter core to leak thus.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple installation, sealing property good filter core mounting structure.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model filter core mounting structure comprises orifice plate and is arranged on the filter core on orifice plate, described filter core is tubulose and the openend be connected with orifice plate is provided with convex shoulder, described orifice plate is provided with the filter core installing hole matched with convex shoulder, the first seal washer is provided with between described convex shoulder and filter core installing hole, be provided with above described filter core and the cover plate of filter core installing hole by threaded adapter, cover plate periphery is provided with external screw thread, the internal thread with external screw thread adaptation is provided with in filter core installing hole, described cover plate is annular plate, the endoporus of cover plate is corresponding with the port of filter core openend unimpeded, the second seal washer is provided with between the lower surface of described cover plate and the upper surface of filter core.Above-mentioned filter core mounting structure eliminates the series installation parts such as original pressing plate, and filter core is installed easier, filter core compresses by the cover plate above filter core, serves the second resealing effect except seal washer thus.
As the further improvement of above-mentioned filter core mounting structure, described cover plate is provided with to be convenient to make cover plate to be threaded with filter core installing hole adaptive to take rotation structure, take preferably rotation structure be cover plate upper surface arrange take turn trough, take the installation and removal that rotation structure facilitates filter core.
Further, scribble sealant layer between described external screw thread and internal thread, sealant layer further increasing the sealing property of filter core mounting structure.
Further, the diameter of bore of described cover plate and the equal diameters of filter core openend port.Make the endoporus of cover plate corresponding with the port of filter core openend unimpeded.
Further, the upper surface of described cover plate and the upper surface flush of orifice plate.Make cover plate coordinate with orifice plate thus more tight, mounting structure is more firm.
After adopting such mounting structure, filter core can directly be installed on orifice plate, instead of original pressing plate syndeton and spring sealed structure, make installation easier thus, and sealing property is better.
Accompanying drawing explanation
Below by way of accompanying drawing and concrete embodiment, the utility model is described in further detail.
Fig. 1 is the utility model filter core mounting structure schematic diagram.
Fig. 2 is filter assemblies schematic diagram after the utility model is installed.

1-filter core, 2-orifice plate, 3-cover plate, 4-first seal washer, 5-second seal washer, 6-filter assemblies, 11-convex shoulder, 21-filter core installing hole, 22-internal thread, 31-external screw thread, 32-takes rotation structure.
Detailed description of the invention
As Fig. 1, shown in Fig. 3 and Fig. 4, the present embodiment filter core mounting structure comprises filter core 1 and orifice plate 2, one end of described filter core 1 is provided with convex shoulder 11, described filter core 1 is tubulose filter core, described orifice plate 2 is provided with the filter core installing hole 21 agreed with convex shoulder 11, the first seal washer 4 is provided with in convex shoulder 11 and filter core installing hole 21 joint place, be provided with above described filter core 1 and the cover plate 3 of filter core installing hole 21 by threaded adapter, described cover plate 2 one weeks cars have external screw thread 31, the close upper opening place car of filter core installing hole 21 has internal thread 22, described cover plate 3 is annular plate, employing is threaded and makes mounting structure more reliable and more stable, sealant layer is coated with between internal thread 22 and external screw thread 31, described annular plate upper surface and the upper surface flush of orifice plate, further increasing sealing property and the stability of filter core mounting structure thus, and the internal diameter of described cover plate 3 is equal with filter core 1 internal diameter, the second seal washer 5 is provided with between the lower surface of described cover plate 3 and the upper surface of filter core 1.Described cover plate 3 upper surface is provided with takes rotation structure 32, this take rotation structure 32 be the symmetry opened of cover plate 3 upper surface take turn trough, take the installation and removal that turn trough facilitates filter core 1.
As shown in Figure 2, above-mentioned filter core mounting structure and pull bar 6, fixed railing 7 form filter assemblies.
The utility model component part is few, and installation process is easy.When gas filtration, first seal washer and the second seal washer are as the first resealing, cover plate plays the effect of the second resealing while compressing filter core, improve the sealing property of mounting structure, save spring sealed joint and pressure plate structure, blowback air more easily purges filter core, makes follow-up blowback effect better.
