Description

A kind of hand-held drum-type soot blower that lengthens

Technical field

The present invention relates to a kind of equipment that is used for cleaning heating surface pipe dust stratification on the boiler that is used in, it is a kind of can the lengthening voluntarily by boiler furnace internal heating surface height, it is to purge dust stratification on the heating surface with compressed air, it is a kind of hand-held drum-type soot blower, it is pulled down conveniently, flexibly mobile, the removing ash of boiler that can be used in the various type of furnaces uses.

Background technology

Boiler heating surface place when operation is easy to dust stratification, so most of enterprises lean in blowing out cooling back and manually purge ash disposal with compressed air, generally blowing grey instrument directly is connected to a blowing pipe with compressed-air hose and comes usefulness, blowing ash with it can only use at lower height, and have only one to blow the ash mouth, cleaning is got up not too clean.In order to clear up the dust stratification that amasss on high position very, can only lean on scaffolding, purge above the people stands in, but stand in the top-operation people danger close of often being not steady on one's legs.So design a kind of can the running in the high-altitude, conveniently moving, the simple and easy slag-blowing equipmemt that can pull down can be subjected to everybody welcome deeply.

Summary of the invention

The present invention proposes a kind of hand-held drum-type soot blower that lengthens, and scheme thes contents are as follows: blow ash and want effective several aspects that have, (1) will have higher compressed air pressure, and this point can both be accomplished, just can accomplish as long as improve compression pump pressure.(2) will have one section to blow grey distance, the area that too closely blows is little, too far can blow unclean.(3) to there be the sufficiently long time of staying, so the deashing time is very long, can increases the weight of working strength of workers.(4) want and can both blow to, no matter high or low.Now design a soot blower, the first, also use compressed air as power source.Adorn an air volume regulating valve at blowing pipe and compressed-air hose junction, be convenient in time close.The second, blowing pipe is the galvanized pipe of several sections two headband gas thread, connects lengthening with screw thread is external, and tube mouth is directly selected 25mm for use.The 3rd, blow the ash head and adopt a plurality of ash mouths that blow, the area that purges in the identical time is wanted many several times like this, reduces the deashing time, subtracts labor intensity clearly.The 4th, blow the ash mouth and will keep a constant effective purging distance with heating surface, the method that solves is that metope commonly used is coated with the paint cylinder structure during with reference to construction and decoration, with one section diameter 50mm of logging car, the wooden stick of length 300mm, the central through hole of a diameter 12mm of middle car, first steel of one section thick 10mm of string in the hole, and bend to a U font, require wooden stick freely to rotate at first steel.Look for one section diameter 40mm again, length also is that the steel pipe of 300mm is done discharge, and two on pipe is used the electric welding good seal, and first steel that will bend to the U font again is welded on the sealing surface, and wooden stick is wanted parallel placement with discharge, keeps spacing 100mm.Centre position at discharge, vertical wooden stick becomes L shaped with discharge, with the blowing pipe of one a headband gas thread of electric welding welding, distinguishes four soot-blowing nozzles of uniform weldering with the tube wall of the blowing pipe relative position that welds on discharge, on the limit each two, other two are uniform.Select for use the seamless pipe of diameter 10mm to do, blow gun length overall 50mm becomes 120 ° angle with tube bending, and the blow gun mouth flattens into the slit of wide 1.5mm, and the air that blows out like this blows the power foot.

Blowing ash manipulation is from being up to low down purging, grasping blowing pipe according to the extreme higher position that will blow earlier wooden cylinder is clung on the tube wall that will purge, moving down at leisure, and because cylinder is wooden, it does not have damage to pipe when the collision tube wall.It is moving in the rollback that comes up of tube wall face purging whole process, and because the discharge that is fixed on the first steel of U font becomes parallel position with cylinder, in upper and lower purge, the about 50～60mm of spacing that mouthpiece also remains unchanged with tube wall all the time is so it is better to blow grey effect.After blowing over one section, if to blow down again one section in face pull down once the joint extension pipe can continue to have operated, dismounting is very convenient.

Beneficial effect of the present invention is simple in structure, and easy accessibility is safe and reliable, processing ease.
