Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment and heat treatment, specifically a device for cooling and drying hot-dip galvanized steel wire after galvanizing. Background Technology

[0002] The galvanized steel wire has a smooth, clean surface, free from cracks, knots, burrs, scratches, and rust. The galvanized layer is uniform, has strong adhesion, and is durable in corrosion resistance, exhibiting excellent toughness and elasticity. The tensile strength should be between 900 MPa and 2200 MPa (wire diameter Φ0.2 mm - Φ4.4 mm). The number of twists (Φ0.5 mm) should be more than 20, and the number of repeated bends should be more than 13.

[0003] Existing patent CN115143728B discloses an accelerated cooling device for hot-dip galvanized steel wire, comprising a body and through holes connected to the two side walls of the body. A steel wire is inserted between the two through holes. A limiting component corresponding to the steel wire is provided on the outer side wall of the body. Sliding grooves are provided in the two side walls of the body, and sliding cavities are slidably provided in the sliding grooves. A pressure device is fixedly provided on one side wall of the sliding cavity. A nozzle is fixedly connected to the end of the pressure device and is oriented towards the steel wire. This invention relates to the field of steel wire processing technology. This accelerated cooling device for hot-dip galvanized steel wire ensures that the two nozzles are always centrally symmetrical when cooling the steel wire, so that the two nozzles and the steel wire are always in a straight line during cooling, avoiding the generation of cooling dead zones and ensuring uniform cooling of the steel wire, thus guaranteeing the cooling effect.

[0004] In existing technologies, the post-galvanizing cooling and drying device for hot-dip galvanized steel wire cools the galvanized steel wire with water and then dries it with air from one side. However, in use, the existing post-galvanizing cooling and drying device for hot-dip galvanized steel wire has uneven internal drying and too low drying speed. This causes the zinc on the surface of the galvanized steel wire that has not been completely cooled to shift to one side, which can easily lead to uneven distribution of the galvanized coating and reduced adhesion between the galvanized steel wire surface and the steel wire. Utility Model Content

[0005] The purpose of this invention is to provide a cooling and drying device for hot-dip galvanized steel wire after galvanizing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a post-galvanizing cooling and drying device for hot-dip galvanized steel wire, the post-galvanizing cooling and drying device comprising: A supporting base plate is provided, on which an annular air guide hood is fixed. The air guide hood has a wire inlet through the middle to accommodate hot-dip galvanized steel wire. The inner wall of the air guide hood has an annular air duct. A ventilator is connected to one side of the air duct. The inner wall of the air duct has an annular array of air outlets. The inner wall of the air outlets has a rotatable arc-shaped baffle that fits against the port of the air outlet.

[0007] Preferably, a support column is fixed on the support base plate, a bearing fixing tube is fixed on the support column, a rotating gear is rotatably mounted on the bearing fixing tube, and an arc-shaped baffle is fixed on the side of the rotating gear.

[0008] Preferably, a motor support is fixed on the support base plate, and a drive gear driven by a motor is mounted on the motor support, the drive gear meshing with a rotating gear.

[0009] Preferably, a bearing is provided at the end of the bearing fixing tube, and the rotating gear is rotatably mounted at the end of the bearing fixing tube via the bearing.

[0010] Preferably, the bearing has an outer cover on its outer side and an inner cover on its inner side.

[0011] Preferably, an annular cover for the air duct is provided on one side of the air guide shroud.

[0012] Preferably, the bearing fixing tube corresponds to the wire inlet, and the inner diameter of both the bearing fixing tube and the wire inlet is larger than the outer diameter of the hot-dip galvanized steel wire.

[0013] Preferably, the width of the arc-shaped baffle is greater than the inner diameter of the air outlet, and the arc of the arc-shaped baffle is between 160° and 180°.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention solves the problems of uneven internal drying and low drying speed in the prior art by installing a ring-shaped air outlet structure. The ring-shaped air outlet is partially blocked by a rotatable arc-shaped baffle at the port of the air outlet, and the air blown out of the air outlet opposite the arc-shaped baffle is reflected, thereby offsetting part of the wind force. While ensuring the rapid flow of air for cooling, the galvanized steel wire is always subjected to the ring-shaped wind. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: Example 1: A post-galvanization cooling and drying device for hot-dip galvanized steel wire includes a supporting base plate 2. An annular air guide hood 1 is fixed on the supporting base plate 2. A steel wire inlet 16 for accommodating the hot-dip galvanized steel wire is provided through the middle of the air guide hood 1. An annular air duct 12 is provided on the inner wall of the air guide hood 1. A ventilator 8 is connected to one side of the air duct 12. An annular array of air outlets 11 is provided on the inner wall of the air duct 12. A rotatable arc-shaped baffle 13 is provided on the inner wall of the air outlet 11. The arc-shaped baffle 13 fits against the port of the air outlet 11. The annular array of air outlets 11 on the inner wall of the air duct 12 and the rotatable arc-shaped baffle 13 on the inner wall of the air outlet 11 block part of the air outlet 11 and make it rotate in an annular manner. This causes the air blown out of the air outlet 11 to rotate in an annular manner. The air blown out of the air outlet 11 opposite to the arc-shaped baffle 13 is rebounded, so that the galvanized steel wire is always subjected to an annular airflow.

[0019] A support column 4 is fixed on the base plate 2. A bearing fixing tube 5 is fixed on the support column 4. A rotating gear 7 is rotatably installed on the bearing fixing tube 5. An arc-shaped baffle 13 is fixed on the side of the rotating gear 7. The rotating gear 7 is installed by installing the support column 4 and the bearing fixing tube 5, so that the rotating gear 7 can be fixed on the bearing fixing tube 5, and then the rotating gear 7 drives the arc-shaped baffle 13.

[0020] A motor support column 3 is fixed on the base plate 2. A drive gear 10 driven by a motor 9 is mounted on the motor support column 3. The drive gear 10 meshes with a rotating gear 7. The drive gear 10 and the rotating gear 7 are driven together, so that the rotating gear 7 rotates with the drive gear 10.

[0021] A bearing 15 is provided at the end of the bearing fixing tube 5. The rotating gear 7 is rotatably mounted at the end of the bearing fixing tube 5 through the bearing 15. By installing the bearing 15 at the end of the bearing fixing tube 5 and fixing the rotating gear 7 on the bearing 15, the rotating gear 7 can be fixed and rotated on the bearing fixing tube 5.

[0022] The bearing 15 has an outer bearing cover 6 on its outer side and an inner bearing cover 14 on its inner side. By installing the outer bearing cover 6 on the outer side of the bearing 15 and the inner bearing cover 14 on the inner side of the bearing 15, the bearing 15 can be fixed on the bearing fixing tube 5 without sliding.

[0023] An annular cover 17 for the air duct 12 is provided on one side of the air guide 1. By providing an annular cover 17 on one side of the air guide 1, the air duct 12 is sealed on one side, so that the air in the air duct 12 can only be blown out from the air outlet 11.

[0024] The bearing fixing tube 5 corresponds to the steel wire inlet 16, and the inner diameter of both the bearing fixing tube 5 and the steel wire inlet 16 is larger than the outer diameter of the hot-dip galvanized steel wire. By limiting the inner diameter of both the bearing fixing tube 5 and the steel wire inlet 16 to be larger than the outer diameter of the hot-dip galvanized steel wire, the galvanized steel wire can pass through the bearing fixing tube 5.

[0025] The width of the arc-shaped baffle 13 is greater than the inner diameter of the air outlet 11, and the curvature of the arc-shaped baffle 13 is between 160° and 180°. Because the width of the arc-shaped baffle 13 is greater than the inner diameter of the air outlet 11, and the curvature of the arc-shaped baffle 13 is between 160° and 180°, part of the airflow blown out from the annularly distributed air outlet is blocked by the arc-shaped baffle 13, thus avoiding wind collision.

[0026] Working principle: By limiting the inner diameter of both the bearing fixing tube 5 and the wire inlet 16 to be larger than the outer diameter of the hot-dip galvanized steel wire, the galvanized steel wire can pass through the bearing fixing tube 5 and enter through the wire inlet 16, thus adapting to the assembly line processing technology of galvanized steel wire. The fan 8 fills the air duct 12 with air, causing the air to be blown out of the annular array air outlet 11. The motor controls the drive gear 10 to rotate, which in turn drives the rotating gear 7 to rotate, causing the arc-shaped baffle 13 to rotate along with the rotating gear 7. As a result, the air blown out of the air outlet 11 is blocked by the rotation of the arc-shaped baffle 13, and the position of the air outlet is determined. It also rotates in a ring to achieve uniform air cooling of the galvanized steel wire. The width of the arc-shaped baffle 13 is greater than the inner diameter of the air outlet 11, and the arc of the arc-shaped baffle 13 is between 160° and 180°. This causes part of the airflow from the ring-shaped air outlets to be blocked by the arc-shaped baffle 13, avoiding air collision. The airflow from the air outlet 11 opposite to the arc-shaped baffle 13 is rebounded, thus offsetting part of the wind force. While ensuring rapid airflow for cooling, the galvanized steel wire is always subjected to ring-shaped airflow, solving the problems of uneven internal air drying and low air drying speed in the background technology.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
