Detailed Description
For a better understanding of the objects, structure and function of the invention, reference should be made to the drawings, FIGS. 1-3, which are included to illustrate the invention.
As shown in fig. 1, the utility model provides a filter screen is used in air sterilizing machine, and the filter screen among the prior art is out of shape easily under high temperature environment, in order to solve the yielding problem of filter screen under high temperature environment, now provides a filter screen, including filter screen body 1, be provided with the reinforcement 3 that promotes filter screen intensity on filter screen body 1, be provided with the wind passageway on the reinforcement 3, still include frame 4 messenger filter screen body 1 and reinforcement 3 fixed connection.
Kill virus bacterium under high temperature environment, current filter screen all needs high temperature resistant, and then sets up reinforcement 3 on filter screen body 1, and reinforcement 3 is plate structure, is provided with a plurality of through-holes 31 on the reinforcement 3. The cross section of filter screen body 1 is the rectangle to reinforcement 3 with filter screen body 1 fixed connection is rectangle platelike structure, the shape looks adaptation of reinforcement 3 and filter screen body 1.
As shown in FIG. 2, the reinforcing member 3 is made of dacron, the through holes 31 of the reinforcing member 3 are uniformly arranged at equal intervals, the shapes of the through holes 31 are regular shapes such as circles, ellipses, polygons and rhombuses, and the density range of the shapes of the through holes 31 is 27000-28000 pieces per square meter. In a preferred embodiment, the reinforcement 3 is a terylene net, the through holes 31 of the terylene net are elliptical, the major axis is 4mm, the minor axis is 3mm, and the density of the terylene net is 27000 pieces/square meter. The dacron net protects filter screen body 1, increases the filter screen deflection, and the filter screen can not soft the deformation about high temperature 80 ℃, guarantees that filtration efficiency and windage isoparametric reach the product requirement.
Filter screen body 1 and reinforcement 3 bond through gluing line hot pressing, and the relative both sides of filter screen body 1 are provided with the dacron net, fix the top and the bottom at filter screen body 1 for increasing filter screen deflection banding strip 2.
The edge banding strips 2 are strip-shaped and are arranged at the top and the bottom of the filter screen body 1.
As shown in fig. 3, frame 4 protects filter screen body 1, increase the filter screen deflection, play and connect filter screen body 1, the dacron net, the effect of banding strip 2, place in frame 4 after filter screen body 1 and reinforcement 3 are fixed, frame 4 includes upper fixed frame 41 and lower fixed frame 44, be provided with left fixed frame 42 and the fixed frame 43 in the right side between upper fixed plate and the lower fixed plate, upper fixed frame 41, lower fixed frame 44, it is provided with extension plate 45 to extend on the lateral wall of left fixed frame 42 and the fixed frame 43 in the right side, thereby make filter screen body 1 fix in frame 4, restrict filter screen body 1's removal.
After the filter screen body 1 is arranged on the frame 4, the top wall and the bottom wall of the frame 4 are provided with the first sealing element 5, and the first sealing element 5 and the frame 4 are fixedly connected through the adhesive tape on the first sealing element 5.
