Bottom end inverted cone-shaped structure, head cover include the downward flanging in the ring wall for being set in frame roof, ring wall top, and ring wall outside wall surface is set
It is rectangular-shaped to have cricoid elastic bumps, raised upper end edge, and raised lower part is arc, and protrusion forms drop-proof structure to filter bag, keeps away
Exempt from crawler belt fall off, crack, ensure that ash-removal effect, elastic protrusion can avoid crawler belt Upper wear, prolong the service life
Further, the frame is by more longitudinal directions circumferentially equally distributed straight muscle, the straight muscle length of straight muscle upper edge
The ring muscle that direction is uniformly arranged is constituted, and ring muscle includes the inner ring muscle being arranged inside straight muscle, the outer shroud muscle in straight muscle outer wall is arranged,
Inner ring muscle, the alternate setting of outer shroud muscle, inner ring muscle outer wall are welded with straight muscle inner wall, and outer shroud muscle inner wall is welded with straight muscle outer wall, described
Ring wall be set in straight muscle upper end outer wall, the bottom cover is set in straight muscle bottom outer wall, and inner ring muscle, outer shroud muscle make frame circumferential surface
For relief, in filter bag deflated or expansion deashing, filter bag height on skeleton circumferential surface is straggly, it is easier to make the dust on filter bag surface
It falls.
Further, the straight muscle bottom end bends inwards.
Further, the protruding apex is equipped with spacing with flanging.
The utility model has the beneficial effects that：Using the above scheme, protrusion forms drop-proof structure to filter bag, avoids crawler belt de-
It falls, crack, ensures that ash-removal effect, elastic protrusion can avoid crawler belt Upper wear, prolong the service life.
Description of the drawings
Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will
It becomes apparent.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram at head cover in the utility model embodiment 1.
Fig. 3 is the partial structural diagram of the utility model middle frame.
Fig. 4 is the structural schematic diagram at head cover in the utility model embodiment 2.
Wherein：1 is head cover, and 11 be ring wall, and 12 be flanging, and 13 be protrusion, and 2 be bottom cover, and 3 be frame, and 31 be straight muscle, 4
It is inner ring muscle for outer shroud muscle, 41.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：- Fig. 3 referring to Fig.1, Filter-bag carcass, including cylindrical type frame further include head cover 1, the frame on 3 top of frame
The bottom cover 2 of frame bottom end, bottom cover 2 are fixed on 3 bottom end of frame, and head cover 2 is set in the top of frame 3, and head cover 2 includes being set in frame
The downward flanging 12 in the ring wall 11 at 3 tops, 11 top of ring wall, 11 outside wall surface of ring wall are equipped with cricoid elastic bumps 13, protrusion
13 upper end is rectangular-shaped, and protrusion is arc downwards by middle part, and protrusion 13 is the rubber block being arranged in 11 outside wall surface of ring wall, convex
Play the cooperation position that 13 installation positions are skeleton and hole on bag filter tubesheet, after filter bag is set on skeleton, the elastic expansion of filter bag
Circle is clamped at raised 13 tops or entire raised 13 upper and lower side of elastic expansion ring covering, and arc and the hole of protrusion 13 coordinate,
Arc promotes skeleton smoothly right angle setting convenient for being inserted in, and protrusion 13 is promoted more to be bonded with hole, after placement, elastic expansion ring
It is clamped at protrusion 13, protrusion 13 forms step backing stop structure with hole junction, effectively avoids crawler belt from being slipped from this, avoids
There is crack, the upper end right-angle structure of protrusion 13 can catch on the end surface side edge of elastic expansion ring, reinforce anti-avulsion effect, while making at this
With larger outer diameter, reinforce the tensioner effect of filter bag and skeleton, prevent from loosening, elastic protrusion 13, can avoid filter bag at this
Place is squeezed by transition, reduces abrasion, extends the service life of filter bag, raised 33 tops are equipped with spacing with flanging 32, convenient for set
If filter bag, space is stopped for elastic expansion ring, frame 3 is by more longitudinal directions circumferentially equally distributed straight muscle 31,31 upper edge of straight muscle
The ring muscle that straight 31 length direction of muscle is uniformly arranged is constituted, and ring muscle includes the inner ring muscle 4 being arranged inside straight muscle 31, is arranged in straight muscle
The outer shroud muscle 41 of 31 outer walls, 4 outer wall of inner ring muscle are welded with 31 inner wall of straight muscle, and 41 inner wall of outer shroud muscle is welded with 31 outer wall of straight muscle, interior
Ring muscle 41, the 4 alternate setting of outer shroud muscle, so that 3 circumferential surface of frame is formed, height is undulated, and in filter bag deflated or expansion deashing, filter bag exists
Height is straggly on skeleton circumferential surface, and under airflow function, filter bag impinges upon on the skeleton circumferential surface that height rises and falls, and skeleton week faces filter bag
It is formed contoured " beating ", it is easier to so that the dust on filter bag surface is fallen, ash-removal effect is more preferable, and 31 bottom end of straight muscle is inwardly curved
Folding, it is inverted cone-shaped structure being arranged convenient for filter bag to make 3 bottom end of frame, and filter bag deflated avoids top from falling at bottom
Dust deposit improves cleaning efficiency in bottom.
Embodiment 2：Referring to Fig.1, Fig. 3, Fig. 4, Filter-bag carcass, including cylindrical type frame further include the head cover on 3 top of frame
1, the bottom cover 2 of frame bottom end, bottom cover 2 are fixed on 3 bottom end of frame, and head cover 2 is set in the top of frame 3, and head cover 2 includes being set in
The downward flanging 12 in the ring wall 11 at 3 top of frame, 11 top of ring wall, 11 outside wall surface of ring wall are equipped with cricoid elastic bumps 13,
It is arc that protrusion 13, which is section, and raised 13 outer end faces are equipped with the inside recess of multiple elder generations, forms friction sucker structure, and protrusion 13 is
Rubber block in 11 outside wall surface of ring wall is set, raised 13 installation positions are the cooperation position of skeleton and hole on bag filter tubesheet,
After filter bag is set on skeleton, the elastic expansion ring of filter bag is clamped at raised 13 tops or the entire protrusion of elastic expansion ring covering
13 upper and lower side, after placement, elastic expansion ring is clamped at protrusion 13, and protrusion 13 forms step backing stop structure with hole junction,
Effectively crawler belt is avoided to be slipped from this, avoids the occurrence of crack, the recess increasing friction force on the outer end face of protrusion 13, and squeezing
Sucker effect is formed after pressure, is tightly bonded with packing, anti-avulsion effect is reinforced, while making that there is larger outer diameter at this, reinforces filter
The tensioner effect of bag and skeleton, prevents from loosening, elastic protrusion 13, can avoid filter bag and is squeezed by transition at this, reduces abrasion,
Extend the service life of filter bag, raised 33 tops are equipped with spacing with flanging 32, and convenient for being arranged filter bag, sky is stopped for elastic expansion ring
Between.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
