[0002] The wire and metal products processing industry relies heavily on surface treatment processes for steel wire, particularly the online phosphating and boronizing processes in continuous heat treatment production lines. Through sorbitization treatment, the steel wire is heated to its austenitizing temperature, rapidly quenched, and then isothermally cooled in a molten salt bath or lead bath at 500-600℃. This process promotes the decomposition of supercooled austenite into sorbite, giving the steel wire high strength and excellent cold deformation properties.

[0003] In the sorbitizing and boronizing production line, steel wire undergoes chemical reactions such as surface rust removal, cleaning, and neutralization in various media including acids, alkalis, and water. During the reaction, the steel wire needs to enter each treatment tank sequentially, and the steel wire will carry the treatment liquid. The liquid will enter the next process tank under the movement of the steel wire, causing various types of pollution and causing wastewater treatment costs to soar. In order to solve the above problems, a hot air drying device for steel wire in the sorbitizing and boronizing production line is urgently needed. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 The hot air drying device for steel wire in the sorbitizing and borosilicate production line includes a high-pressure blower 1. The outlet end of the high-pressure blower 1 is connected to an air storage box assembly 2, and the outlet end of the air storage box assembly 2 is connected to a universal air duct 4. An air knife nozzle 9 is fixed at the bottom of the universal air duct 4, and a transition assembly 3 for collecting the treatment liquid is provided below the air knife nozzle 9. A steel wire 5 is threaded through the interior of the transition assembly 3.

[0028] The transition component 3 is detachably connected to the air storage box component 2, and the air knife nozzle 9 is provided with multiple nozzles.

[0029] The universal duct 4 is a support-free universal bamboo joint duct. The support-free universal bamboo joint duct body is composed of multiple rotatable ring-shaped connecting sections. It is made of high temperature resistant support-free universal bamboo joint duct, which can be freely bent to any angle and stably fixed. The universal duct 4 is connected to the air knife nozzle 9.

[0030] The air knife nozzle 9 and the universal air duct 4 are fixedly connected by a threaded interface, and a sealing ring is set at the connection between the air knife nozzle 9 and the universal air duct 4. The width of the air knife nozzle 9 is between 0.01mm and 2mm. The gap width needs to be selected according to the actual wire diameter. The smaller the gap, the higher the airflow speed. It is sufficient to ensure that the air knife nozzle 9 will not damage the wire when supplying air to it. The included angle between the air knife nozzle 9 and the steel wire 5 is between -5° and 0° (0° is when the airflow of the air knife nozzle 9 is perpendicular to the surface of the steel wire). However, in actual applications, it can be finely adjusted and optimized through the universal air duct 4.

[0031] The high-pressure blower 1 has an outlet pipe 7 fixed at its outlet end, and the end of the outlet pipe 7 is fixedly connected to a connecting pipe 6 via a flange. The bottom of the high-pressure blower 1 is equipped with a bracket 8. If necessary, an air filter can be added to the air inlet end of the high-pressure blower 1 to filter the incoming air and prevent fine particulate matter in the air from affecting the normal operation of the high-pressure blower 1. The air filter adopts existing equipment, and its structure and working principle will not be described in detail here. The end of the connecting pipe 6 is fixed with a pressure-stabilizing air storage box 201. The air storage box assembly 2 includes a pressure-stabilizing air storage box 201. The top of the pressure-stabilizing air storage box 201 is fixed with multiple air outlets 202 for air discharge.

[0032] As a supplement, the pressure-stabilizing gas storage tank 201 can also be equipped with a pressure gauge to display the pressure inside the pressure-stabilizing gas storage tank 201. An exhaust valve is installed on the gas outlet 202 to open and close the gas outlet 202. An inlet valve is installed between the connecting pipe 6 and the pressure-stabilizing gas storage tank 201 to ensure sealing while controlling the gas entering the pressure-stabilizing gas storage tank 201. The pressure gauge, inlet valve and exhaust valve are all existing equipment, and their detailed connection methods will not be described here. All connections are sealed with sealing rings.

[0033] By adopting the above technical solution, the high-pressure blower 1 is a Roots blower. The blown air enters the small pressure-stabilizing air storage box 201 through the outlet pipe 7 and the connecting pipe 6. When the high-pressure blower 1 is working, there is friction between the impeller and the air, and between the bearing and the shaft. Some mechanical energy is converted into heat energy, resulting in the outlet air temperature being slightly higher than the ambient temperature. At the same time, since the production line is continuous, the high-pressure blower 1 is always working and does not stop. After a while, the air in the pressure-stabilizing air storage box 201 heats up quickly due to the work done. Then, the hot air passes through the outlet 202 and the universal air duct 4, and is then... The blower nozzle 9 continuously blows air onto the surface of the continuously running steel wire 5. On the one hand, the air pressure blows the solution medium off the surface of the steel wire 5, and on the other hand, the hot air dries the wet surface of the steel wire 5 more quickly, thereby reducing the amount of the previous treatment liquid carried into the next process and thus reducing the cost of pollutant disposal. The high-pressure blower 1, in conjunction with the air storage tank assembly 2, not only blows air onto the surface of the steel wire 5 to blow the treatment liquid off, but also utilizes the heating characteristics of the Roots blower to dry the surface of the steel wire 5 more quickly, achieving the effect of reducing the amount of the previous treatment liquid carried into the next process.

[0034] Specifically, such as Figures 3 to 5 As shown, the gas storage tank assembly 2 also includes two fixed structural members 203 welded to the side of the pressure-stabilizing gas storage tank body 201. Fixed bolts 204 are installed inside the fixed structural members 203. The pressure-stabilizing gas storage tank body 201 is installed on the side of the transition groove 301, which is located between the two processing grooves.

[0035] The transition assembly 3 includes a transition trough 301 installed on one side of the pressure-stabilizing gas storage tank 201. A drain valve is provided on the side of the transition trough 301 to drain the liquid in the transition trough 301. The liquid level must not exceed the support roller 305. A folded edge 303 is provided on the top of the transition trough 301. A guide side plate 302 is provided at the connection between the transition trough 301 and the folded edge 303. The guide side plate 302 has a certain slope. The fixing structure 203 is fixedly connected to the folded edge 303 by fixing bolts 204. The transition assembly 3 also includes inlet and outlet troughs 304 opened at both ends of the transition trough 301. The steel wire 5 passes through the interior of the inlet and outlet trough 304. Below the steel wire 5, multiple support rollers 305 installed inside the transition trough 301 are provided. The support rollers 305 are higher than the liquid level of the transition trough 301. The steel wire 5 is located above the support rollers 305 to support the steel wire 5 and prevent the steel wire 5 from falling excessively and immersing into the treatment liquid in the transition trough 301.

[0036] By adopting the above technical solution, after the steel wire 5 is processed in the pre-processing tank, when it enters the post-processing tank, it first enters the transition tank 301 through one of the inlet / outlet slots 304, is erected above the support roller 305, and is discharged outward through the other inlet / outlet slot 304. When the air knife nozzle 9 blows the processing liquid off the steel wire 5, if the liquid splashes to both sides, it can be guided into the interior of the transition tank 301 under the action of the guide side plate 302. The pressure stabilizing air storage tank 201 is installed on the side of the transition tank 301 by fixing bolts 204. Through the set transition component 3, the transition tank 301 is installed between the two processing tanks, which facilitates the collection of the processing liquid blown off the steel wire 5.

[0037] Working principle: After being processed in the pretreatment tank, the steel wire 5 enters the transition tank 301 through one of the inlet / outlet troughs 304 and is mounted above the support roller 305. It is then discharged outward through the other inlet / outlet trough 304 and enters the posttreatment tank. During this process, the high-pressure blower 1 works. When air enters the high-pressure blower 1, there is friction between the impeller and the air, and between the bearing and the shaft, which causes the outlet air temperature to rise. The hot air enters the small pressure-stabilizing air storage box 201 through the outlet pipe 7 and the connecting pipe 6. At this time, the hot air passes through the air outlet 202 and the universal air duct 4, and is continuously blown onto the surface of the continuously running steel wire 5 by the air knife nozzle 9. Since the air knife nozzle 9 is vertically located above the steel wire 5, the treatment liquid on the surface of the steel wire 5 is blown off by the air pressure. At the same time, the hot air can dry the steel wire 5 more quickly. The steel wire 5 can only enter the posttreatment tank after being dried by passing through multiple air knife nozzles 9, reducing the amount of pretreatment liquid carried into the next process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
