Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and
"outside" refers respectively to the direction towards or away from geometric center of specific component.
A kind of formaldehyde gas filter device, as shown in Figure 1, including filter box 1, the left and right sides of filter box 1 is distinguished
It is communicated with air inlet pipe 2 and escape pipe 3.Three notches 11 are offered in the front side wall of filter box 1, are respectively mounted in per pass notch 11
There are the filter assemblies 4 being embedded in inside filter box 1.
As shown in Fig. 2, filter assemblies 4 include filter frame 41 and filtration members 42, the side of filter frame 41 along its length
It is inserted into notch 11 (referring to Fig. 1), the handle 6 that the other side is equipped with convenient for pull.The filtration members 42 used in the present embodiment for
Activated carbon fibre plate, activated carbon fibre plate can be removably mounted in filter frame 41 by screw.
It is fixedly connected to attachment strap 43 as shown in Figure 1, being equipped at the side of handle 6 and its upper and lower ends in filter frame 41,
It is connected with clamping mechanism 5 on attachment strap 43, while offering locating slot in the side wall of filter box 1 and positioned at the upper and lower of notch 11
12, by the cooperation of clamping mechanism 5 and locating slot 12 to be fixed to being fully inserted into the filter frame 41 in notch 11.
As shown in figs. 1 and 3, which includes U-shaped elastic slice 51, clamping block 52 and hemispherical raised line 53.U-shaped elastic slice
The one end of 51 side with attachment strap 43 far from filter box 1 is vertical to be fixed, and the other side and clamping block 52 are fixed.In locating slot 12
Upper side wall offer with clamping block 52 cooperate clamping groove 121.When clamping block 52 is embedded in clamping groove 121, filter frame
41 are completely embedded into in notch 11 and position and fix.
As shown in figure 3, setting its cross sectional shape in ladder to make clamping block 52 be easier to be embedded in clamping groove 121
It is arc transition between shape and its adjacent side, it can be made to slide into card by the architectural characteristic of clamping block 52 itself in this way
It is lighter when in access slot 121；It is therebetween in simultaneously face contact when clamping block 52 is embedded in clamping groove 121, but also
Clamping block 52 and clamping groove 121 are not susceptible to mutual wear phenomenon.
As shown in figs. 1 and 3, hemispherical raised line 53 is arranged in the right side of clamping block 52 and at upper part, while in card
Right side wall in access slot 121 is equipped with the limiting groove 1211 cooperated with hemispherical raised line 53.When 52 link slot 121 of clamping block
When interior, hemispherical raised line 53 is also embedded in limiting groove 1211, so that filter frame 41 connect more firm with filter box 1
Gu.
As shown in figs. 1 and 3, U-shaped elastic slice 51 need to be first compressed when extracting filter frame 41 out makes clamping block 52 be detached from clamping groove
121, and entire U-shaped elastic slice 51 is respectively positioned in locating slot 12 at this time, operating space is smaller, therefore in U-shaped elastic slice 51 far from filter frame
41 one end is fixedly installed crushing block 54, is evenly equipped on crushing block 54 several for increasing the anti-skidding salient point 5411 of friction.This
Sample just can compress U-shaped elastic slice 51 by pressing crushing block 54, to facilitate the taking-up work of filter frame 41.
As illustrated in fig. 1 and 2, the left and right sides of filter frame 41 and be located at every side peripheral region offer seal groove 411,
The sealing joint strip 7 of adaptation is placed in seal groove 411.When filter frame 41 is fully inserted into notch 11, sealing joint strip 7 with it is close
The slot bottom of sealing groove 411 and the side wall at notch 11 abut.Sealing joint strip 7 can block the seam between filter frame 41 and notch 11
Gap increases leakproofness, so that the gas in filter box 1 is not easy to leak from notch 11.
Specific implementation process: it is first directed at the position of itself and notch 11 when installation filter frame 41, inwardly pushes filter frame 41.When
Filter frame 41 completely closely sealed notch 11 when, by crushing block 54 compress U-shaped elastic slice 51, and continue inwardly push U-shaped elastic slice 51, this
When U-shaped elastic slice 51 on clamping block 52 will slide into automatically in clamping groove 121, while hemispherical raised line 53 can also be embedded in limit
In the groove 1211 of position, to realize the fixation of filter frame 41.By air inlet pipe 2 be connected to other pernicious gases such as formaldehyde pipeline or
In equipment, after the adsorption filtration of activated carbon fibre plate, clean gas is discharged pernicious gas from escape pipe 3.
When activated carbon fibre plate is replaced, U-shaped elastic slice 51 is first compressed, while passing through handle 6 for filter frame 41
Outside pull is replaced the filtration members 42 in filter frame 41, mistake so that entire clamping block 52 is detached from clamping groove 121
Filter frame 41 is still reusable.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
