Abstract

The utility model discloses a frame of a pocket-type air filter, which is mainly composed of a rectangular outer frame and more than two filtering material support rings, wherein notches are arranged inside the outer frame, the filtering material support rings are arranged in a frame which is surrounded by the outer frame in parallel, the filtering material support rings are used to support pocket mouths of filtering materials and are rectangular steel strip rings, the upper edges and the lower edges of the filtering material support rings are fixed in corresponding notches inside the outer frame, the rectangular outer frame is composed of plastic section bars which are detachably inserted and assembled, plastic battens which are used to fix the filtering material support rings are also arranged in the frame, notches are arranged on the plastic battens, the left edge and the right edge of the filtering material support rings are respectively arranged in the notches of two neighboring plastic battens, and the upper ends and the lower ends of the plastic battens are fixed in corresponding notches inside the outer frame. The frame has more reasonable structure design, an inner frame and the outer frame can be conveniently assembled and disassembled and can be used repeatedly, and the waste of an existing product due to integral replacement is avoided.

Description

Pocket type air cleaner framework

Technical field:

The utility model relates to the air-treatment unit of central air-conditioning, exactly is a kind of middle framework of imitating the pocket type air cleaner.

Background technology:

The housing and the filtrate bracing ring of the bag filter that generally uses all adopt galvanized steel plain sheet or other metal material to make at present, whole outside framework and filtrate are non-removable fixed structure with being connected of bracing ring, make that filtrate and framework all are disposable uses, can't recycle and reuse, when descending to not reaching, the media filtration effect filters when requiring, a whole cover all will be scrapped, again change one group of new air cleaner, and in fact the framework of this moment does not damage, can normally use fully, it is just passable only to need to change filtrate; Existing this product structure causes a large amount of raw-material wastes, and use cost is along with raw-material rise is also significantly increasing.

The utility model content:

At prior art above shortcomings part, the purpose of this utility model is to provide a kind of pocket type air cleaner framework that can replacing filtrate for convenience detach, has realized the reusability of framework, the waste of having avoided the existing product integral replacing to cause.

For achieving the above object, the utility model is taked following technical scheme: a kind of pocket type air cleaner framework, mainly form by a rectangle housing and plural filtrate bracing ring, the inboard of housing is provided with notch, the filtrate bracing ring is located in the framework that housing surrounds side by side, the filtrate bracing ring is used to support the sack of filtrate, the filtrate bracing ring is the rectangle steel zone circle, the last bottom of filtrate bracing ring is fixed in the respective slot of housing inboard, described rectangle housing is to be formed by the detachable inlaying grafting assembly of plastic material, also be provided with the plastic layer that is used for fixing the filtrate bracing ring in the framework, plastic layer is provided with notch, two limits are separately positioned in the notch of two adjacent plastic layers about the filtrate bracing ring, and the upper and lower side of plastic layer is fixed in the respective slot of housing inboard.

The further technical scheme of the utility model is, described rectangle housing is to be formed with the plastic material inlaying grafting assembly that two two ends have corresponding inserting groove by the plastic material that two two ends have a plugboard.

The utility model further technical scheme is, attacked a hole on the described plugboard, and the inserting groove outer wall has through hole with a silk corresponding position, hole, by screw plugboard is fixed in the inserting groove.

By technique scheme as can be known, housing of the present utility model is taked easy-to-dismount inlaying grafting assembly structure, the sack of filtrate can directly be wrapped on the filtrate bracing ring and be fixed by being stuck in housing notch and the press strip notch, need not again the filtrate sack be rivetted on bracing ring, remove and install just very simple and convenient, when the filter effect decline of air cleaner can not be satisfied instructions for use, only need pull down housing, take out the filtrate sack bracing ring in the inside casing, old filtrate taken off to change from filtrate sack bracing ring can normally use again after new filtrate is reinstalled, greatly reduce existing product and carry out the use cost that integral replacing is paid.

The beneficial effect that the utility model is compared with prior art had is, scientific structure design is reasonable, loads and unloads simple and conveniently, has realized the repeated use of internal and external frame, the waste of raw materials of having avoided the existing product integral replacing to cause has also reduced consumer's use cost significantly.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, pocket type air cleaner framework provided by the utility model mainly is made up of a rectangle housing 1 and plural filtrate bracing ring 4, the inboard of housing 1 is provided with notch, filtrate bracing ring 4 is located in the framework that housing surrounds side by side, filtrate bracing ring 4 is used to support the sack of filtrate, the last bottom of filtrate bracing ring 4 is fixed in the respective slot of housing 1 inboard, housing 1 selects for use ABS engineering plastics section bar inlaying grafting assembly to form, 45 ℃ of plastic material two ends cutting angles, the butt joint back forms 90 ℃ of right angle housings, the structure of the butt joint plastic material of adjacent setting is different, but cooperatively interact, in conjunction with Fig. 2 and shown in Figure 3, wherein the two ends of a section bar 10 are provided with plugboard 5, another root section bar 11 is provided with the inserting groove 6 that matches with plugboard 5, plugboard 5 inserts in the inserting groove 6 finishes detachable inlaying grafting assembly, rectangle housing 1 is to be formed by two plastic materials 10 and two plastic material 11 mutual inlaying grafting assemblies, consider the fastness that housing 1 is fixed, silk hole 7 can attacked on the plugboard 5, inserting groove 6 outer walls have through hole 8 with silk 7 corresponding positions, hole, by screw 9 plugboard 5 is fixed in the corresponding inserting groove 6, only needs during dismounting screw backed out and get final product.Also be provided with the plastic layer 3 that is used for fixing filtrate bracing ring 4 in the framework, have notch 2 on the plastic layer 3, the cross section of notch 2 is the U-lag mouth, referring to shown in Figure 4.Filtrate bracing ring 4 is the rectangle steel zone circle, referring to shown in Figure 5.Two limits are separately fixed in the notch 2 of two press strips 3 of adjacent setting, referring to shown in Figure 6 about filtrate bracing ring 4.The upper and lower side of press strip 3 is fixed in the respective slot of outter frame profile inboard.

Shown in Figure 1 is the frame structure that seven press strips 3 are set, the quantity of press strip 3 is according to using needs to set, wherein the press strip 3 of two ragged edges is that integral body is arranged in the notch of outter frame profile inboard, and under the normal condition, the quantity of filtrate bracing ring 4 is lacked one than the quantity of press strip 3.

The foregoing description only as to of the present utility model a kind of comparatively preferred embodiment; be not that protection domain to claim is construed as limiting; contribution of the present utility model just has been to realize that the internal and external frame of pocket type air cleaner detachably is repeatedly used; not breaking away from the utility model protection category, must belong within this patent protection domain with interior any simple and easy distortion and modification.
