Abstract
The utility model relates to a shell for an air filter. The shell comprises a rectangular framework which is formed by encircling four frames, wherein the cross section of each frame is in a U shape. The shell is characterized in that the head end of each frame is a reducing variable-cross-section U-shaped opening structure, the tail end of each frame is of a corner seal structure and is provided with an inserting seam, the head end of the previous frame and the tail end of the next frame are sequentially assembled in a plugging manner and connected together in a spot welding manner to form an integral framework. After the shell is spliced, a resistance welding point is added on each corner end surface of the shell, so that the rigidness of the filter shell is improved. The shell has the characteristics that 1. the four frames are completely consistent, so that mass production can be realized; 2. the overall rigidness is strong, so that the reliability in installation of the filter is guaranteed; 3. the potential danger of the glue leakage of four seamed edges can be prevented; 4. the variable-cross-section U-shaped end surface and the corner seal are matched and positioned with each other, so that no special production positioning tool is needed.
Description
Technical field
The utility model relates to nuclear engineering air purifying process field, and specifically a kind of air pre cleaner housing, is applicable to nuclear engineering air cleaning system.
Background technology
In nuclear engineering air cleaning system, the consumption of air pre cleaner is huge at present.The service life that high efficiency particulate air filter is put thereafter in the direct impact of quality of air pre cleaner.The subject matter of air pre cleaner is at present: 1, and housing end face seam crossing is 45 ° of pieces, flexible joint causes filter integral rigidity to reduce; Under piece, increase angle bar pad and can strengthen filter rigidity, make man-hour but can increase considerably filter, affect make efficiency.2, housing seamed edge piece leaks glue, after filter sealing completes, will increase specially gel resin operation; If adopt mechanical system gel resin, the chip meeting contaminated filter device core body of fluid sealant, if adopt organic solvent gel resin, the volatilization of organic solvent can be polluted workshop, infringement workers ' health.
Summary of the invention
The purpose of this utility model is just for above-mentioned prior art situation and custom-designed a kind of new air filter housing, and this version can guarantee filter rigidity, does not leak glue, makes simple, time saving and energy saving.
The purpose of this utility model is achieved through the following technical solutions: a kind of air pre cleaner housing, enclosed the rectangular frame forming by four edges frame, the cross section of frame is U-shaped, wherein: the head end of every frame is the U-shaped hatch frame of closed-entry variable cross-section, tail end is that corner seals structure indwelling have plug joint, and the tail end of the head end of last frame and a rear frame successively plug-in mounting coordinates and spot welding connects into a general frame.After housing splicing, increase electric resistance welding solder joint at four jiaos of end faces, strengthen filter housings rigidity
In the utility model, described rectangular frame is square frame.The U-shaped hatch frame of closed-entry variable cross-section of frame head end and the corner seals structure of tail end are to be all directly stamped to form by mould.
Main feature of the present utility model is:
1. four edges frame is in full accord, suitable production in enormous quantities;
2. integral rigidity is strong, guarantees the reliability that filter is installed;
3. four hidden danger that seamed edge leaks glue have been stopped;
4. the U-shaped end of variable cross-section is mutually pegged graft and is coordinated, locates with corner seals end face, without the special positioning tool of making.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is four jiaos of syndeton schematic diagrames.
Fig. 3 is the U-shaped structural representation of frame one end variable cross-section.
Fig. 4 is frame other end corner seals structural representation.
In figure: 1 is frame, 1.1 is the U-shaped hatch frame of closed-entry variable cross-section, and 1.2 is the U-shaped end face of closed-entry variable cross-section, and 1.3 is corner seals structure, and 1.4 is plug joint.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As Figure 1-4: a kind of air pre cleaner housing, enclosed the square frame forming by four edges frame 1, the cross section of frame is U-shaped, wherein: the head end of every frame is the U-shaped hatch frame 1.1 of closed-entry variable cross-section, tail end is that corner seals structure 1.3 indwelling have plug joint 1.4, and the tail end of the head end of last frame and a rear frame successively plug-in mounting coordinates also spot welding to connect into a general frame.After housing splicing, increase electric resistance welding solder joint at four jiaos of end faces, strengthen filter housings rigidity
The U-shaped hatch frame of closed-entry variable cross-section of frame head end and the corner seals structure of tail end are to be all directly stamped to form by mould.
When plug-in mounting coordinates, the U-shaped hatch frame 1.1 of variable cross-section inserts in plug joint 1.4, and end face 1.2 and the laminating of corner seals bottom that variable cross-section is U-shaped, to realize the location completely of frame 1.Carry out electric resistance welding at end face coincidence position again, increase filter housings rigidity.
Claims (3)
1. an air cleaner housing, enclosed the rectangular frame forming by four edges frame, the cross section of frame is U-shaped, it is characterized in that, the head end of every frame is the U-shaped hatch frame of closed-entry variable cross-section, tail end is that corner seals structure indwelling have plug joint, and the tail end of the head end of last frame and a rear frame successively plug-in mounting coordinates and spot welding connects into a general frame.
2. air cleaner housing according to claim 1, is characterized in that: rectangular frame is square frame.
3. air cleaner housing according to claim 1, is characterized in that: the U-shaped hatch frame of closed-entry variable cross-section of frame head end and the corner seals structure of tail end are to be all directly stamped to form by mould.
