Abstract
The utility model provides a low pressure dust removal pulse jetting pipe positioner. It is including jetting pipe, jetting pipe box pipe, gas bag pipeline, preceding end support, card, position casing and back end support, the preceding end support of the effective welding of jetting on the dust removal wallboard and back end support fixed stay, jetting pipe box pipe one end links to each other with the gas bag pipeline of dust removal jetting system, and the other end links to each other with the jetting pipe, position casing is the welding of protruding disc on the card, the installation accuracy of jetting pipe has been guaranteed to position casing's upper end and the butt joint of jetting pipe nozzle, and height, the depth of parallelism, the straightness that hangs down do not reach the requirement between nozzle and card because of installation reason or jetting pressure take place to have avoided the jetting pipe, and lead to the filter bag to break, or gas injection does not arrive the condition at the bottom of the filter bag, has prolonged the life of filter bag, sparingly the maintenance expense of dust -collecting equipment.
Description
Technical field
This utility model relates to the low pressure dedusting pulse blowing pipe positioner of sack cleaner especially sack cleaner.
Background technology
Bag type dust collector filter bag adopts compression air to carry out jetting deashing, and deashing mechanism is controlled valve etc. by gas bag, injection tube and electromagnetic pulse and forms.Often arrange filter bag outlet top in filter chamber and be equipped with an injection tube, on the downside of injection tube, just filter bag center is provided with winding-up mouth, every injection tube is equipped with a pulse valve and communicates with compression air gas bag.During bag type dust collector deashing, pulse valve opened by electromagnetic valve, compression air is opened electromagnetic pulse winding-up through spray by setup program by dust disposing device (differential pressure or timing, Non-follow control), compression gas with the extremely short short time in order through each pulse valve in injection tube nozzle induction be several times as much as injection tolerance air enter filter bag, form air wave, filter bag is made to be produced expansion sharply and impact shock by bag mouth to bottom, cause very strong deashing effect, shake off the dust on filter bag.
Summary of the invention
In order to solve in existing cleaner installation process the problem of hi-Fix between injection tube and card, this utility model provides a kind of low pressure dedusting pulse blowing pipe positioner, which ensure that the installation accuracy that ensure that injection tube, extend the service life of filter bag, save the maintenance expense of dust-collecting equipment.
This utility model solves its technical problem and be the technical scheme is that a kind of low pressure dedusting pulse blowing pipe positioner, it includes injection tube, injection tube sleeve pipe, gas bag pipeline, front-end bracket, card, locating sleeve and rear end support, described injection tube supports with the front-end bracket being welded on dedusting wallboard and rear end support are fixing, described injection tube sleeve pipe one end is connected with the gas bag pipeline of dedusting injection system, the other end is connected with injection tube, described locating sleeve is that convex plate-like is welded on card, the upper end of described locating sleeve is docked with injection tube nozzle, described locating sleeve centrage is consistent with the centrage in card hole, described locating sleeve internal diameter is bigger less than 1mm than nozzle od, angle between described low pressure dedusting pulse blowing pipe positioner nozzle centerline and cloth bag axis is less than 1 °.
Angle between low pressure dedusting pulse blowing pipe positioner nozzle centerline and cloth bag axis is less than 1 °, thus ensure that the installation accuracy of injection tube, ensure that the effect of pulse jet, avoid injection tube and do not reach requirement because installing height, the depth of parallelism, perpendicularity between reason or jetting pressure generation nozzle and card, and cause that filter bag breaks, or Gas injection is less than the situation at the bottom of filter bag.
The beneficial effects of the utility model are: provide a kind of low pressure dedusting pulse blowing pipe positioner, which ensure that the installation accuracy of injection tube, ensure that the effect of pulse jet, avoid injection tube and do not reach requirement because installing height, the depth of parallelism, perpendicularity between reason or jetting pressure generation nozzle and card, and cause that filter bag breaks, or Gas injection is less than the situation at the bottom of filter bag, described low pressure dedusting pulse blowing pipe positioner reduces the Pressure Drop of dust-collecting equipment, extend the service life of filter bag, save the maintenance expense of dust-collecting equipment.
