Abstract
The utility model discloses a pulse blowing pipe which particularly solves the problems of the existing blowing pipe that the air blowing bundle can not be vertical to a pattern board, the dust removing capacity is not enough, etc. The utility model uses a blowing opening (4) of the blowing pipe (1) is provided with a current guiding device (2) which presents in a cylindrical shape, and the center of the current guiding device (2), the center of the blowing opening (4) and the center of a filter bag are at the same axial line and are vertical to the surface of the pattern board. The utility model has the advantages of easy fabrication, convenient installation, etc.
Description
Affiliated technical field: the utility model relates to a kind of filter-bag blowing device of pulsed jet cloth filter, especially relates to a kind of pulse jet pipe.
Background technology: at present, a kind of like this filter bag pulse jet pipe of sack cleaner is disclosed on the market, its design feature is: open several injection holes on steel pipe, during installation, injection hole is aimed at the filter bag that has been installed on the card, during filter bag ash removal down, the pulse valve starting, compressed air sprays in the filter bag by injection hole along the winding-up pipe.Because the winding-up tube wall is thinner, the aperture is an ellipse, and compressed air is by be difficult for forming the gas bundle of a vertical card, and it is bad easily to cause sack to blow, and problem such as filter bag ash removal power deficiency occurs.
Summary of the invention: the purpose of this utility model provides and a kind ofly can form a vertical card gas bundle, avoids blowing bad filter pocket mouths, the pulse jet pipe that winding-up tolerance is increased.
For achieving the above object, solution of the present utility model is: the winding-up mouth place at the winding-up pipe is provided with cylindrical circular flow diverter, on the flow diverter center should coexist an axis in jet mouthful center and filter bag center, and perpendicular to the card face.
On the face of cylinder of flow diverter, have several through holes symmetrically.
After adopting this structure; owing on the winding-up pipe, be provided with flow diverter; compressed air directly sprays into filter bag through the flow diverter guiding; in addition, again owing on flow diverter, having through hole, by the effect of inside and outside differential pressure; through hole from flow diverter sucks air; increase winding-up tolerance, both strengthened the deashing ability of filter bag, protected filter bag again.
Description of drawings: the utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the main cross-sectional schematic of a kind of pulse jet pipe of the utility model.
Among the figure: 1, winding-up pipe, 2, flow diverter, 3, through hole, 4, winding-up mouthful.
The specific embodiment: in the drawings, locate to be provided with the flow diverter (2) that is cylinder type at the winding-up mouth (4) of winding-up pipe (1), on flow diverter (2) center should coexist an axis in jet mouthful (4) center and filter bag center, and perpendicular to the card face; On the face of cylinder of flow diverter (2), have several through holes (3) symmetrically.
When a kind of pulse jet pipe is in running order, the pulse valve starting, compressed air sprays in the filter bag by winding-up mouthful (4) and flow diverter (2) along winding-up pipe (1), simultaneously, because the effect of external and internal pressure difference, air enters in the flow diverter (2) from the through hole (3) on the flow diverter (2), thereby has increased winding-up tolerance, reaches the deashing purpose.
Claims (2)
1, a kind of pulse jet pipe is characterized in that: the winding-up mouth (4) at winding-up pipe (1) locates to be provided with cylindrical circular flow diverter (2), on flow diverter (2) center should coexist an axis in jet mouthful (4) center and filter bag center, and perpendicular to the card face.
2, a kind of pulse jet pipe according to claim 1 is characterized in that: have several through holes (3) symmetrically on the face of cylinder of flow diverter (2).
