Description

A kind of detachable filter

The utility model relates to a kind of filter, and especially a kind of detachable central air-conditioning filter belongs to the filed of air conditioning used unit.

Traditional galvanized sheet framework filter, appearance poor, perishable, and complexity is installed, and installation workload is big, filtrate disassembly, cleaning inconvenience, and sealing property is bad, and filtering accuracy is not high.

The purpose of this utility model is to provide a kind of structure simple and direct, easy for installation, and workload is few, and filtrate is unpicked and washed conveniently, good seal performance, the detachable filter that filtering accuracy is high.

The purpose of this utility model is achieved through the following technical solutions: a kind of detachable filter, include framework, filtrate, its special character is that described framework is inside and outside two quadrilateral frames, all be provided with crisscross inside and outside steel wire grid on four limit outside frameworks and the four limit inner frames, be arranged with baffle plate on correspondence two frames of four limit outside frameworks, four limit inner frames insert in the baffle plate, constitute an integral body with four limit outside frameworks, accompany filter material layer between the inside and outside steel wire grid.

Above-mentioned four limit internal and external frames are made of the H type framework of band crossbeam, the phase-contact surface of every adjacent two frameworks and the angle sum of each frame cross section are 90 ° in the four limit internal and external frames, be 45 ° of the bests with the angle of framework cross section separately wherein with phase-contact surface, so that the framework unification is blocked, be fit to industrialized mass.The parallel edges at H type cruciform bracing two ends is divided into parallel short sides and parallel long limit, parallel short sides is connected with the lagging parallel with crossbeam, parallel short sides is outside when constituting four limit outside frameworks, the slot that lagging and crossbeam constitute inserts L type fixed head and fixes, the parallel long limit only keeps on one side, also be connected with horizontal link plate on the long limit that keeps, be used for fixing steel wire grid on the corresponding horizontal link plate.Be arranged with baffle plate on correspondence two frames of described four limit outside frameworks, this baffle plate is connected on the crossbeam of H type framework.Described H type framework also can make following shape, and the lagging that parallel short sides is connected is communicated with, again with in the crossbeam separated one section.

Described H type framework adopts aluminium alloy extrusions to make, and is easy to disassembly, cleaning, and appearance looks elegant, not perishable.

During assembling, four limit internal and external frames install and fix respectively, put into filter material layer then, at last four limit inner frames are inserted in the baffle plate symmetrical set on corresponding two frames of four limit outside frameworks to get final product.

The inside and outside framework in detachable filter of the present utility model four limits is in conjunction with tight, good airproof performance has solved the difficult problem of leaking out of general filter, has improved filtering accuracy, used framework is fit to mass industrialized production, only need block and can assemble use, structure is simple and direct, and is easy to install, firmly, filtrate is unpicked and washed conveniently, and framework adopts aluminium alloy extrusions, has solved galvanized sheet framework filter appearance poor, a corrosion-prone difficult problem.

Description of drawings:

Fig. 1-the utility model most preferred embodiment front view;

The A-A cutaway view of Fig. 2-Fig. 1;

The used outside framework cross-sectional view of Fig. 3-most preferred embodiment;

The used inner frame cross-sectional view of Fig. 4-most preferred embodiment.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying enforcement of the present utility model and operating position.

Most preferred embodiment, referring to figs. 1 to Fig. 4, the detachable filter of this most preferred embodiment, include framework, filtrate, in described framework is, outer two quadrilateral frames, four limit outside frameworks 1 are the H type framework of band crossbeam 6, in four limits, the phase-contact surface 7 of every adjacent two frameworks and the angle α of each frame cross section 8 in the outside framework, β is all 45 °, tailor unification, be fit to suitability for industrialized production, the parallel edges at H type cruciform bracing two ends is divided into parallel short sides 9 and parallel long limit 10, parallel short sides 9 is connected with the lagging parallel with crossbeam 11, and it is fixing that the slot that lagging 11 and crossbeam 6 constitute is inserted with L type fixed

head

12, and 10 on parallel long limit keeps on one side, also be connected with horizontal link plate 13 on the long limit that keeps, be fixed with steel wire grid 3 on the horizontal link plate of four side transverse frame correspondences, be provided with on correspondence two frames of four limit outside frameworks 1 in baffle plate 4, the four limit inner frames 2 insertion baffle plates 4, constitute an integral body with four limit outside frameworks, accompany filter material layer 5 between the inside and outside steel wire grid 3.

The utility model four limit inner frames 2 are also for being with the H type framework of crossbeam 6, with different being of four limit outside frameworks: the lagging that its H type framework parallel short sides connects is connected, in the crossbeam separated one section, and the H type frame manufacture size that constitutes four limit inner frames is less than four limit outside frameworks, so that the four limit inner frames outside framework of packing into easily when installing, and reach the clamping filtrate, the purpose of favorable sealing effect.

The inside and outside framework in four limits of the utility model most preferred embodiment adopts aluminium alloy extrusions to make, and appearance looks elegant is not perishable, can solve galvanized sheet framework filter appearance poor, a corrosion-prone difficult problem.

The inside and outside framework in filter of the present utility model four limits is in conjunction with tight, and good airproof performance has solved the difficult problem of leaking out, and the filtering accuracy height, and is easy to install, and filtrate is unpicked and washed conveniently.
