Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention discloses a kind of High efficiency filter seal structure, improve purification efficiency and clean-up effect to reach, reduce the object of production and use cost.
As shown in Figure 2,3, a kind of High efficiency filter seal structure, is applied to and is provided with on the filter of folding type filter element, and the upper and lower end of filter core 2 is provided with protection web plate 3, and hermetically-sealed construction comprises the frame 1 being arranged at both sides, filter core 2 folded edge place; And be arranged at the housing (not shown) of other both sides; The top and bottom of frame 1 are all fixedly connected with protection web plate 3.
Because folded edge is when pouring into glue sealing, distortion can be there is, subregion is caused not have glue to inject sealing, sealing effectiveness is poor, therefore, the frame being positioned at both sides, folded edge place changes into and directly fixing with protection web plate 3 by the present invention, ensure that the sealing effectiveness of filter core folded edge, because the distortion of folded edge causes subregion to there is not glue sealing when avoiding injecting glue; By arranging frame on the both sides at filter core folded edge place, both sides are original housing in addition, which reduces the use amount of glue, reduce production and use cost on the one hand, decrease the setting time of glue on the other hand, improve operating efficiency.
Frame 1 comprises upper side frame 11 and lower frame 12, and upper side frame 11 is fixedly connected with lower frame 12, and upper side frame 11 and lower frame 12 junction are also provided with locking and fixing device.Locking and fixing device comprises the draw-in groove 18 being arranged at upper side frame 11 lower end, and the flexible clamp piece 19 connected and fixed mutually with draw-in groove 18 being arranged at lower frame upper end, and flexible clamp piece 19 is symmetrically arranged two first quarter moon arc structures.Draw-in groove 18 is arcuate structure, when draw-in groove 18 is fixed with flexible clamp piece 19, due to the effect of pressure, flexible clamp piece 19 inwardly shrinks and enters draw-in groove 18 inside, rear flexible clamp piece opens fixing, when upper side frame 11 being removed with lower frame 12, by pulling flexible clamp piece 19, flexible clamp piece forced contraction, departs from draw-in groove.By the mating reaction of draw-in groove and flexible clamp piece, be convenient to the Assembly And Disassembly of frame, flexibility is stronger.In addition, key also can be adopted to connect or sell other connected modes etc. such as connection and upper and lower side frame is fixed, specifically not limit.
Locking and fixing device also can be the draw-in groove 18 being arranged at lower frame 12 upper end, and the flexible clamp piece 19 etc. connected and fixed mutually with draw-in groove 18 being arranged at upper side frame lower end, and specific constructive form does not limit.
Upper side frame 11 is provided with the bayonet socket 13 corresponding with protecting web plate 3 with lower frame 12 side.The end of fixed network board 3 is stretched in bayonet socket 13, by connecting and fixing between frame and fixed network board, ensure that stability and the sealing of connection, decreases the use amount of glue, reduces use cost.
Upper side frame 11 and lower frame 12 junction are provided with the hold down gag for being fixed filter core limit.Hold down gag comprises the upper pressure strip 14 and lower pressure strip 15 that are arranged at upper side frame 11 and lower frame 12 junction.Hold down gag also comprises at least one groove 16 be arranged on pressure strip 14, and is arranged at the convex edge 17 that lower pressure strip 15 matches with groove 16.Before upper and lower side frame is fixing, the edge of filter core being put between upper pressure strip 14 and lower pressure strip 15, by being compressed by filter core while being locked by upper and lower side frame, avoiding filter core to produce mobile or distortion, ensure that dusty air is all through filter element filtering, improves sealing effectiveness.Hold down gag also can be at least one convex edge 17 be arranged on pressure strip 14, and is arranged at the groove 16 matched with convex edge 17 on lower pressure strip 15.Can be effectively fixed by filter core, concrete fixed form does not limit.
In addition, the quantity of groove and convex edge can be one or more, realizes multi-stage sealed being fixed, and improve sealing effectiveness, concrete quantity does not limit.
Upper side frame 11 and lower frame 12 are also provided with buffer sealing device with the junction of protection web plate 3.Buffer sealing device is sealing gasket 20, by arranging sealing gasket 20, ensureing frame and the sealing of protection web plate junction, avoiding the leakage of dusty air, improving the depuration quality of air.
Sealing gasket can be rubber or plastics, while raising sealing effectiveness, goes back the fixation pressure between available buffer protection web plate and frame and friction, the damage of avoiding device.
Buffer sealing device also can be multiple sealing strip etc. be arranged side by side, and plays multi-stage sealed effect, improves sealing effectiveness, and reduces use cost.
The invention discloses a kind of High efficiency filter seal structure, be applied to and be provided with on the high efficiency particulate air filter of folding type filter element, the upper and lower end of described filter core is provided with protection web plate, described hermetically-sealed construction comprises the frame being arranged at both sides, described filter core folded edge place, and is arranged at the housing of other both sides; The top and bottom of described frame are all fixedly connected with described protection web plate.By arranging frame in the both sides at filter core folded edge place; and be fixedly connected with between frame with protection web plate; ensure that the sealing effectiveness of filter core folded edge; because the distortion of folded edge causes subregion to there is not glue sealing when avoiding injecting glue; decrease the use amount of glue simultaneously; reduce production and use cost on the one hand, decrease the setting time of glue on the other hand, improve operating efficiency.
Meanwhile, by being fixed by filter core, and buffer sealing device being set at frame and the junction of protection web plate, improving sealing effectiveness, ensureing purification of air quality.
Be more than the description to the embodiment of the present invention, by the above-mentioned explanation to the disclosed embodiments, professional and technical personnel in the field realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
