Abstract
The utility model discloses a hole drawing device of an injection pipe, comprising the injection pipe, wherein a through hole is arranged on the end face of the injection pipe; a mould conveying rod is arranged right below the through hole and a bulge is arranged on the mould conveying rod; a stretching mould is sleeved outside the bulge; a pressing sleeve is arranged right above the through hole; and a through hole II is arranged at a position of the pressing sleeve corresponding to the through hole. The hole drawing device of the injection pipe disclosed by the utility model has the advantages of simple structure, convenience for manufacturing and wide application range; and the stretching mould is made of high-strength tool steel so that the service life of the stretching mould is guaranteed and the service life can reach to more than 10,000times.
Description
Technical field
The utility model belongs to the environmental protection field, is specifically related to a kind of pulling eye device that is used for the fixing winding-up pipe of low pressure pulse dust remover.
Background technology
Sack cleaner is widely used in the gas cleaning that industries such as coal-burning boiler, chemical industry, building materials produce the dust occasions, and fixedly the sack cleaner of tubular type action of low-voltage pulse injection technology is a preferred equipment wherein.Be source of the gas with compressed air during this type of deashing, when the control system sent signal, the through type pulse valve that is contained on the voltage stabilizing gas bag was just opened; What gas bag was interior calms the anger to come out in abrupt release; And the nozzle from winding-up pipe sends in the every filter bag, and filter bag receives the impulse vibration of deashing air-flow, and the filter bag wall obtains very big acceleration; Thereby make dust layer cleared filter bag, fall into ash bucket.
Above every row's filter bag, establish a winding-up pipe, in filter bag, carry the deashing air-flow through the nozzle on the pipe, nozzle bore has nothing in common with each other, and guarantees that each bar filter bag ash removal intensity is even.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, and a kind of pulling eye device that is used for the fixing winding-up pipe of low pressure pulse dust remover is provided.
Technical scheme: in order to achieve the above object, the utility model is specifically accomplished like this: a kind of pulling eye device of the pipe of jetting comprises the winding-up pipe; Winding-up pipe end face has through hole; Be provided with under the through hole and send tringle, send tringle to be provided with convexity, the protruding outer stretching die that is with; Be provided with gland directly over the through hole, and gland and through hole opposite position have through hole two.
Wherein, said stretching die bottom is tubaeform, and the top is cylindrical, and can select tool steel for use is raw material.
Wherein, said through hole is greater than the stretching die top and less than the stretching die bottom.
Wherein, said through hole two is greater than the stretching die top.
Beneficial effect: the utlity model has following advantage:
1, simple in structure, easy to make, wide accommodation;
2, stretching die has adopted high-intensity tool steel to process, and has guaranteed the service life of stretching die, makes it the life-span to have reached more than 10,000 times.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing, a kind of pulling eye device of jetting and managing that the utility model provides comprising winding-up pipe 1, and winding-up pipe 1 end face has through hole 11, is provided with under the through hole 11 and send tringle 2, send tringle 2 to be provided with convexity 21, the protruding outer stretching die (3) that is with; Be provided with gland 4 directly over the through hole, and gland 4 has through hole 2 41 with through hole 11 opposite positions; Said stretching die 3 bottoms are tubaeform, and the top is cylindrical; Through hole 11 is greater than stretching die 3 tops and less than stretching die 3 bottoms; Through hole 2 41 is greater than stretching die 3 tops.
During concrete work, the pipe 1 of will jet is placed on the fixed mount, fixes, and stretching die 3 is linked to each other with affecting device again, through rotation stretching die 3 is managed 1 inwall through hole 11 from winding-up and pulls out, and has the vertical winding-up mouth of pipe of rounding off pulling out position formation.
