Description

Technical Field

[0001] This utility model belongs to the field of alloy wire cooling, and in particular relates to a zinc-aluminum alloy steel wire production device. Background Technology

[0002] In the field of metallic materials, zinc-aluminum alloy steel wire is widely used in many key fields such as construction, communication, and transportation because it combines the corrosion resistance of zinc with the high strength and lightweight properties of aluminum. For example, it is used as cable-stayed bridge cables, overhead power transmission line conductors, and load-bearing components for marine engineering. Its product performance is directly related to the structural stability and service life of related projects.

[0003] However, in the actual production process of zinc-aluminum alloy steel wire, especially in core processes such as alloy smelting, hot-dip galvanizing of steel wire, or heat treatment after continuous drawing, zinc is prone to oxidation, which has become a key technical bottleneck restricting the improvement of product quality and production efficiency.

[0004] During the cooling stage, an inert atmosphere is usually used as the cooling medium, such as N2 and CO2 mixed together. Traditional pre-mixing methods require mixing and storage space, while real-time mixing methods often suffer from uneven mixing. In addition, the gas consumption is large and the economy is poor. Summary of the Invention

[0005] In view of this, the present invention aims to propose a zinc-aluminum alloy steel wire production device to solve the problems of low mixing efficiency and high gas consumption in inert atmosphere.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a zinc-aluminum alloy steel wire production device, comprising: Fixed air duct, with one end closed and the other end open; A rotating air duct is arranged coaxially with a fixed air duct, and the air outlet is inserted into the fixed air duct through the closed end. The air outlet is used to jet N2 and form a back pressure zone in the fixed air duct. Several air outlets with angles of attack are evenly arranged on the circumference of the rotating air duct to push the gas out obliquely and accelerate it when rotating. The blades are arranged in several pairs and are correspondingly installed at each air outlet with an angle of attack. They are used to apply circumferential force to the gas ejected from the air outlet with an angle of attack when rotating. The air inlet is provided in several places and is evenly distributed throughout the fixed air duct wall corresponding to the back pressure zone; The CO2 buffer chamber is connected to the air inlet and is used to introduce CO2. The heat-insulating airflow guide is installed inside the fixed air duct to isolate the rotating connection of the rotating air duct from the CO2 airflow and to smoothly guide the airflow to the blades.

[0007] Furthermore, there is a certain distance between the air inlet and the air inlet hole of the CO2 buffer chamber, so that after the CO2 enters, it can flow a certain distance along the outer wall of the fixed air duct.

[0008] Furthermore, the axis of the air inlet is arranged at an acute angle to the outer wall of the fixed air duct.

[0009] Furthermore, the air inlet is an air inlet that is inclined toward the opening end of the fixed air duct.

[0010] Furthermore, the air inlet angle is 45 degrees.

[0011] Furthermore, the heat insulation guide section is a conical cylinder, and its cross-sectional area gradually increases from the side closer to the opening end of the fixed air duct to the side farther away.

[0012] Furthermore, the rotating duct is equipped with an angled air outlet and has a certain wall thickness.

[0013] Furthermore, the angle of attack of the air outlet with an angle of attack is 30-60 degrees.

[0014] Furthermore, the air inlet end of the rotating duct is rotatably connected to the connecting part, which is used to connect the N2 pipeline.

[0015] Furthermore, the rotating duct is equipped with a drive unit to drive its rotation.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This device uses a fixed duct and a rotating duct that can rotate relative to each other. When the rotating duct rotates, it outputs CO2 airflow, creating a back pressure zone in the fixed duct. At the same time, during the rotation, some gas is blown out from the angle-of-attack outlet. The angle of attack of the outlet and the rotation create a gas acceleration effect. Combined with the circumferential throwing effect created by the rotating blades, the formation of the rotating airflow is enhanced. The CO2 input into the CO2 buffer chamber is attracted by the pressure of the back pressure zone and enters at an angle through the air inlet, mixing with the enhanced rotating airflow, resulting in a more uniform mixture.

[0017] 2. This device introduces CO2 airflow and allows it to flow a certain distance along a fixed duct, enabling it to exchange heat with the gas inside the duct first. During the mixing process, further heat exchange occurs, thereby improving the uniformity of temperature output and making it easier to control the final output temperature when cooling the alloy steel wire.

[0018] 3. By setting up a heat-insulating guide section, this device can isolate the rotating position of the rotating duct from the CO2 introduction area, preventing the temperature rise generated during rotation from affecting the gas temperature. At the same time, guiding the gas can reduce the cavitation effect on the rotating duct, which is a rotating component, and also reduce noise. On the other hand, guiding the airflow to the blades to participate in the throwing action can quickly mix the two airflows, further improving the uniformity of the mixed airflow.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0022] It should be noted that the descriptions of "left," "right," "left side," "right side," "upper part," "lower part," "top," and "bottom" in this utility model are defined based on the orientation or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and are not intended to indicate or imply that the described structure must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0023] In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Referring to the accompanying drawings, this embodiment of a zinc-aluminum alloy steel wire production apparatus includes: Fixed air duct 1 has a closed end and an open end; a flange is provided at the open end for connecting to a channel for cooling the alloy wire, and a bearing seat is provided at the closed end for forming a rotating connection with the rotating air duct 2.

[0025] A rotating duct 2, coaxially arranged with the fixed duct 1, has its outlet end inserted into the fixed duct 1 via the closed end. The outlet end is used to jet N2 and form a back pressure zone within the fixed duct 1. Several angle-of-attack outlets 9 are evenly arranged circumferentially on the peripheral wall of the rotating duct 2 to obliquely push and accelerate the gas during rotation. The rotating duct 2 is a hollow pipe with a diffuser section in the middle, i.e., a region with increased cross-sectional area, thus obtaining a larger surface area. Simultaneously, the wall has a suitable thickness, which helps to form angle-of-attack outlets 9 capable of accelerating gas output. Combined with the blades 8, this creates a stronger throwing effect. Therefore, it is easier to obtain a rotating, uniformly mixed flow of gas without increasing the flow rate and input gas pressure. This is to improve the uniformity of the mixed gas and, when forming a swirling flow to cool the metal wire, the rotating gas can increase the contact area and frequency with the metal wire while consuming less gas, thereby reducing the probability of oxidation. Ultimately, the air blown out from the outlet of the rotating duct 2 forms a cooling effect with uniform blowing in the middle and swirling around the perimeter.

[0026] The blades 8 are arranged in several pairs and are correspondingly set at each angle-of-attack air outlet 9. They are used to apply circumferential force to the gas ejected from the angle-of-attack air outlet 9 when rotating. The blades 8 mainly accelerate the gas at the angle-of-attack air outlet 9 to form an oblique throwing effect, which is more conducive to forming a rotating airflow.

[0027] The air inlet 5 is provided with several holes that are evenly distributed throughout the wall of the fixed air duct 1 corresponding to the back pressure zone; The CO2 buffer chamber 6, connected to the air inlet 5, is used to introduce CO2. The CO2 buffer chamber 6 is designed to reduce the temperature difference between CO2 and N2, and to facilitate gas introduction. Specifically, the air inlet 5 is an inclined hole facing the opening of the fixed duct 1 at a 45-degree angle. This design ensures that the CO2 moves quickly towards the blades 8 after entering. Furthermore, its inclination direction, opposite to the inlet direction of the air inlet 7, acts as a deflector, preventing excessive CO2 intake pressure and velocity from affecting the mixing effect. Proportional valves can be installed at the air inlet 7 and the air inlet end of the rotating duct 2 to control the flow rates of N2 and CO2, strictly controlling the mixing ratio of the two gases. Generally, a 95:5 ratio of N2 to CO2 can be selected.

[0028] The heat-insulating guide section 10, located inside the fixed air duct 1, isolates the rotating connection of the rotating air duct 2 from the CO2 airflow and smoothly guides the airflow to the blades 8. Specifically, the heat-insulating guide section 10 is a conical cylinder with a gradually increasing cross-sectional area from the side closest to the opening of the fixed air duct 1 to the side furthest away. On the one hand, it can isolate the large-area temperature rise generated when the rotating air duct 2 rotates from being conducted to the cooling airflow. On the other hand, the gas entering through the air inlet 5 will form a certain temperature and stable temperature field inside the heat-insulating guide section 10 as it flows along it, which helps to maintain a stable temperature rise when the rotating air duct 2 rotates and ensures the reliable operation of the device.

[0029] In this embodiment, there is a certain distance between the air inlet 7 and the air inlet 5 of the CO2 buffer chamber 6, allowing the CO2 to flow a certain distance along the outer wall of the fixed duct 1 after entering. This arrangement is to ensure that the CO2 flows a certain distance along the outer wall of the fixed duct 1, thereby exchanging heat with the gas inside the fixed duct 1 to a certain extent. This reduces the large temperature fluctuations during the final mixing and swirling process of the two gases, making it easier to control the temperature of the cooling airflow. Generally, as the final cooling stage, the gas temperature is controlled at 20-25℃. To further enhance the effect of stabilizing the temperature in advance, the axis of the air inlet 7 is arranged at an acute angle to the outer wall of the fixed duct 1, and its tilt direction is opposite to that of the air inlet 5, forming the aforementioned deflection effect.

[0030] In this embodiment, the angle of attack of the angle-of-attack air outlet 9 is 30-60 degrees. Specifically, setting it to 45 degrees is most effective, as it can reliably accelerate the gas that serves as the power source for the rotation of the swirling gas.

[0031] In this embodiment, the air inlet end of the rotating duct 2 is rotatably connected to the connecting part 3, and the connecting part 3 is used to connect the N2 pipeline. Specifically, the connecting part 3 is a flange pipe with a bearing seat, which is rotatably connected to the rotating duct 2. After the connecting part 3 is connected to the N2 pipeline, the N2 pipeline and the connecting part 3 are fixed, and the rotating duct 2 rotates.

[0032] In this embodiment, the rotating duct 2 is provided with a drive unit 4 to drive its rotation. The drive unit 4 is specifically a drive motor, which forms a transmission connection with the rotating duct 2 through a pulley and a V-belt. Other types of drive forms can also be provided as needed.

[0033] In use, connect the connecting part 3 to the N2 pipeline and the air inlet 7 to the CO2 pipeline. Drive the rotating air duct 2 to rotate through the drive part 4. Control the amount of gas entering by controlling the proportional valve inside the air inlet 7 and the rotating air duct 2 through the control system.

[0034] After N2 enters the rotating air duct 2, part of it is blown out from the air outlet and forms a back pressure zone in the fixed air duct 1. The other part is blown out from the air outlet 9 with an angle of attack and forms a swirling flow through acceleration and the throwing action of the blades 8. The gas entering the CO2 buffer chamber 6 will enter through the air inlet 5 under the negative pressure attraction of the back pressure zone, and then flow through the heat insulation guide section 10 and be thrown together by the blades 8, thus forming a uniformly mixed rotating gas. This rotating gas and the gas blown out from the air outlet in the middle form a flow pattern of central flow and peripheral wrapping, which acts on the alloy wire, thus forming a cooling method with low flow rate, low gas consumption, but strong wrapping effect, preventing zinc from oxidizing.

[0035] The sensors, controllers, and control programs mentioned above are all existing technologies and will not be elaborated upon further.

[0036] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
