Abstract
The utility model discloses a pickled strip steel purging device, comprising an air chamber, and a left bracket and a right bracket which are arranged at two sides of a strip steel conveying track, wherein the left bracket and the right bracket are respectively vertically fixed with nuts, which are screwed on an adjustment lead screw; the top end of the adjustment lead screw is fixedly provided with an adjustment handle, the air chamber hangs at the bottom of the adjustment lead screw and is fixedly matched with a radial rotating shaft of the adjustment lead screw; the air chamber is transversely arranged above the strip steel conveying track, the bottom of the air chamber is sequentially provided with air nozzles, and the air nozzle on the left side inclines toward the left side and the air nozzle on the right side inclines toward the right side. According to the utility model, the air chamber is arranged above the pickled strip steel conveying track, the bottom of the air chamber is sequentially provided with the air nozzles, the pickled strip steel is rinsed and then transversely purged through the air nozzles above the air chamber prior to being dried, in order to remove water remaining on the surface and the sides of the strip steel and avoid rusting on the surface of the strip steel, thereby enhancing quality control ability of pickling line and playing a crucial role in promoting product quality.
Description
Technical field
The utility model relates to a kind of cold-rolling pickling device, relates in particular to a kind of pickled steel strip blow device.
Background technology
Hot-strip enter cold rolling before must to the band steel carry out prewashing, pickling, rinsing and baking operation, dust and the grease of hot water cleaning to remove belt steel surface mainly adopted in prewashing, the iron rust (as iron oxide, di-iron trioxide and tri-iron tetroxide etc.) of belt steel surface is mainly removed in pickling, the chlorion of belt steel surface is mainly removed in rinsing, the main moisture of removing belt steel surface of oven dry is avoided belt steel surface generation corrosion.
Above-mentioned prewashing, pickling, rinsing and baking operation all carry out on the pull pickler group.Often finding in process of production that belt steel surface or limit portion are residual has a large amount of water marks, be sent to rolling process prepare rolling before, serious corrosion phenomena just takes place in the rolled band steel surface, this quality to cold-rolled products causes and seriously influences and unnecessary economic loss.In the prior art, take to reduce unit operation speed, improve the pH value of washings, measures such as periodic replacement compression roller, but effect and not obvious, still there are watermark in belt steel surface or limit portion.
The utility model content
At weak point of the prior art, the utility model provides a kind of pickled steel strip blow device that can remove residual water mark on the pickled steel strip surface effectively, adopt this device can improve the surface quality of pickled steel strip, belt steel surface generation corrosion when avoiding steel rolling effectively.
The pickled steel strip blow device that the utility model provides, comprise air chamber, left socle and right the support, described left socle and right support are fixedly installed on the left and right sides that the band steel is carried track respectively, the nut that difference retaining thread hole vertically is provided with on it, the nut of described left and right sides rotation set is respectively being regulated on the screw mandrel, the top of described adjusting screw mandrel fixedly installs regulating handle, described air chamber by two ends be suspended in respectively the bottom of regulating screw mandrel and with the bottom of regulating screw mandrel radially turning cylinder to secure fit, described air chamber is horizontally installed on the top that the band steel is carried track, the bottom of air chamber sets gradually air nozzle, the air nozzle of described air chamber bottom left tilts to the left, and the air nozzle on right side tilts to the right.
Further, the two ends of described air chamber are provided with air inlet pipe respectively, and air inlet pipe is connected with compressed-air actuated source of the gas.
The beneficial effects of the utility model: the utility model adopts and above the conveying track of pickled steel strip air chamber is set, the bottom of air chamber sets gradually air nozzle, band steel after the pickling through after the rinsing before entering oven dry, laterally purge to steel band by the air nozzle on the air chamber, to remove belt steel surface and the residual water mark of limit portion, it is further dry to pass through dryer again, guarantee the dry no watermark of belt steel surface, avoid the belt steel surface corrosion, make the quality control ability of pickling unit reach raising, play most important promoting product quality.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
Accompanying drawing is a structural representation of the present utility model, as shown in the figure, the pickled steel strip blow device comprises air chamber 1, left socle 2 and right support 3, left socle 2 and right support 3 are fixedly installed on the left and right sides that the band steel is carried track respectively, the top that the band steel is carried track is stretched at the top of left socle 2 and right support 3, the nut 4 that difference retaining thread hole vertically is provided with on it, the nut 4 of left and right sides rotation set is respectively being regulated on the screw mandrel 5, the top of regulating screw mandrel 5 fixedly installs regulating handle 6, the two ends of air chamber 1 be suspended in respectively the bottom of regulating screw mandrel 5 and with the bottom of regulating screw mandrel 5 radially turning cylinder to secure fit (in the present embodiment, the bottom of regulating screw mandrel 5 cooperates with air chamber by bearing), air chamber 1 is horizontally installed on the top that the band steel is carried track, the bottom of air chamber 1 sets gradually air nozzle 7 (14 air nozzles are set in the present embodiment), the air nozzle 7 of air chamber 1 bottom left tilts to the left, and the air nozzle 7 on right side tilts to the right.
The two ends of air chamber 1 are provided with air inlet pipe 8 respectively, and air inlet pipe 8 is connected with air compressor machine.Air chamber 1 is a cylinder, carries compressed air by air compressor machine to air inlet pipe 8, and compressed air enters cylinder by air inlet pipe 8 and is stored in the cylinder, unifies air feed by cylinder to air nozzle 7 again.
When using this pickled steel strip blow device, can regulate the height of air chamber by the regulating handle 6 of regulating screw mandrel 5 tops, thus the distance of regulating air nozzle 7 distance band steel, so that regulate the impulsive force that compressed air purges belt steel surface.Rotate up and regulate screw mandrel 5, drive on the air chamber 1 and move, the impulsive force that air nozzle 7 purges belt steel surface weakens; Be rotated down and regulate screw mandrel 5, drive air chamber 1 and move down, air nozzle 7 purges the impulsive force of belt steel surface and strengthens.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
