Abstract
A spray pipe for water mist quenching of a steel pipe. The invention relates to a conveying device for a quenching medium on a waste heat quenching device. Comprises a water pipe, a gas pipe, a nozzle, a water joint, a gas guide pipe and a water guide pipe; the trachea eccentric settings is in the water pipe, through connecting piece fixed connection on the water pipe inner wall, and a plurality of nozzles of outside water pipe towards trachea biased one side equipartition, be equipped with air inlet, water inlet on the nozzle, thereby air inlet, water inlet on the nozzle link to each other with aqueduct and the air duct that radially runs through the pipe wall and communicate water pipe and trachea respectively. The invention does not need to be specially provided with a booster pump for supplying water. In addition, in order to improve the uniformity of water quenching, the spacing distance between the nozzles is set by taking the standard that the fan-shaped water mist sprayed by adjacent nozzles is overlapped from the middle of the fan waist, so that the uniformity and consistency of the water mist sprayed on the steel pipe rotation line are high.
Description
Technical field
The present invention relates to the e Foerderanlage of the quenchant on a kind of waste heat quenching device, relate in particular to the injection spray pipe of the water fog quenching device in a kind of weldless steel tube processing.
Background technology
At present, weldless steel tube is used more and more wider model, as oil well pipe, mechanical workout pipe etc., be used to produce oil well casing, mechanical workout has quenched and tempered steel and a non-hardened and tempered steel with pipe, adopt the weldless steel tube of quenched and tempered steel manufacturing to need to carry out quench treatment aborning, adopt the weldless steel tube of non-hardened and tempered steel manufacturing to need normalizing treatment.Comparatively speaking, the weldless steel tube cost that adopts quenched and tempered steel to make is low, has the stronger market competitiveness.Modulation is quenched shrend, oil quenching, and the production environment of oil quenching is abominable, and shrend is then different, environment is not had influence, and cost is low.Shrend divides mainly that trough inner water is quenched, the outer shrend of groove, trough inner water is quenched relatively and steel pipe, have following defective, the steel pipe of heating is after entering tank, and steel tube surface can produce boiling, form surperficial steam film, for steel pipe internal-surface, it is slower that the steam film at top is opened speed, makes speed of cooling inhomogeneous, be lower than the required critical cooling velocity of martensitic transformation as this partial speed of cooling, this part will lose the effect of quenching.The outer water quenching technology of groove has multiple Implementation Modes, and as outer tube layer stream, inner axial tube jet flow etc., but never a complete device can be implemented such technology.
Summary of the invention
The present invention is directed to above problem, provide a kind of can be on a turning spur of steel pipe even spray feed shrend medium, thereby improve the injection spray pipe of the water spray quenching of steel tube of shrend quality.
Technical scheme of the present invention is: comprise water pipe, tracheae, nozzle, water swivel, gas joint, it also comprises airway, aqueduct; Tracheae is eccentrically set in the water pipe, be fixedly connected on the pipe inner wall by web member, the uniform plurality of nozzles of one side of outside water pipe, setovering towards tracheae, nozzle is provided with inlet mouth, water-in, thus the inlet mouth on the nozzle, water-in respectively with run through the aqueduct that tube wall is communicated with water pipe and tracheae diametrically and link to each other with airway.
Described nozzle is provided with the water jet that can spray fan-shaped water smoke, and the sector of fan-shaped water smoke is parallel to the axial direction due of injection spray pipe, and the fan-shaped water smoke of adjacent nozzle ejection is overlapping from the middle part beginning of fan waist.
Nozzle of the present invention, for water smoke is mixed, in nozzle, mix preceding because the mobile characteristic that can form negative pressure of gas according to water, gas, tracheae is eccentrically set in the water pipe, reduces the air guide distance of airway, increase the flow velocity of high pressure gas in the nozzle hybrid chamber, the negative pressure that forms, the effect of suction is arranged, and the pressure that can reduce to supply water does not need to be provided with specially topping-up pump and supplies water like this.In addition, in order to improve the homogeneity of shrend, the spacing distance between the nozzle is that standard is provided with " the fan-shaped water smoke of adjacent nozzle ejection is overlapping from the middle part beginning of fan waist ", like this, is sprayed on water smoke homogeneity, consistence height on the steel pipe turning spur.

Embodiment
The present invention comprises water pipe 5, tracheae 3, nozzle 1, water swivel 6, gas joint 7 as shown in Figure 1, 2, and it also comprises airway 2, aqueduct 4; Tracheae 3 is eccentrically set in the water pipe 5, be fixedly connected on water pipe 5 inwalls by web member, the uniform plurality of nozzles 1 of one side of outside water pipe 5, setovering towards tracheae 3, nozzle 1 is provided with inlet mouth, water-in, thus the inlet mouth on the nozzle 1, water-in respectively with run through the aqueduct 4 that tube wall is communicated with water pipe 5 and tracheae 3 diametrically and link to each other with airway 2.
Nozzle 1 is provided with the water jet that can spray fan-shaped water smoke, and the sector of fan-shaped water smoke is parallel to the axial direction due of injection spray pipe, and the fan-shaped water smoke of adjacent nozzle 1 ejection is overlapping from the middle part beginning of fan waist.
The present invention in use, as shown in Figure 3, when the long steel pipe 8 of processing length, about an injection spray pipe is set respectively, the injection spray pipe termination links to each other with tapering positioning head 10, and the fan-shaped water smoke of adjacent nozzle 1 ejection is overlapping from the middle part beginning of fan waist, and steel pipe 8 is positioned at 9 outsides, overlap of water smoke.
