Description

Technical Field

[0001] This invention relates to the field of wire coil production equipment technology, and more specifically, to a blower device for a high-speed wire coil air-cooling roller conveyor. Background Technology

[0002] During the online coil production process, after the steel bars are extruded from the extruder, they are evenly scattered on the roller conveyor in a spiral arrangement. Because the temperature of the steel bars is too high at this time, in order to obtain suitable crystals, the steel bars on the roller conveyor need to be forced to be cooled by air. After cooling, the spiral coils fall into the coiling device for subsequent steel bar collection and transportation.

[0003] When the coiled wire falls onto the roller conveyor, as Figure 1 As shown, the two ends are overlapped (labeled as area A), while the middle part is spread out (labeled as area B). The heat dissipation efficiency of area A and area B is different. Because the coil overlaps more tightly in area A, its cooling speed is significantly slower than that in area B. This results in the coil in area B having already cooled down, while the coil in area A is still at a high temperature, leading to uneven cooling of the coil.

[0004] To address the aforementioned issues, existing high-speed wire rod cooling roller conveyor fan arrangements typically involve installing multiple rows of fans below the roller conveyor. A common fan arrangement is three rows, with one row of fans installed in each of the two A zones and one B zone. Since the wire coils in the A zone are more densely packed, the number of fans is relatively increased, while the number of fans in the B zone is relatively sparsely packed. However, this fan arrangement results in a large number of fans, which not only increases construction costs and reduces economic efficiency but also occupies more production space and a larger floor area. Summary of the Invention

[0005] To address the problems of the prior art, this invention provides a blower device for a high-speed wire rod cooling roller conveyor. The airflow generated by the blower rotates and blows onto the conveyor surface of the roller conveyor. The diameter of the airflow rotation matches the diameter of the wire coil. The airflow continuously blows onto area A for a longer time than it blows onto area B, thereby making the airflow in area A greater than that in area B.

Each blower 2 is fixedly installed with a vertically arranged air duct 3 that extends to the bottom of the roller conveyor 1. The air duct 3 is cylindrical and has an air guide. The airflow generated by the air guide rotates and blows towards the wire coil 4 on the roller conveyor 1, and the rotation center axis of the airflow is perpendicular to the conveying surface of the roller conveyor 1.

[0048] The airflow generated by the air guide rotates and blows onto the wire coil 4 on the roller conveyor 1. The diameter of the airflow rotation matches the diameter of the wire coil 4. The airflow stays for a significantly longer time at the overlapping part of the wire coil 4 than at the middle part. This avoids affecting the cooling speed and cooling effect due to the overlapping of the two ends of the wire coil 4, ensuring the uniformity of cooling of the wire coil 4, reducing the number of fans 2, and saving production costs.

[0049] Further, the air guide part comprises a cover plate 5, a first driving part 6 and a first air blowing cylinder 7, the cover plate 5 is sleeved on the top of the air duct 3 and is rotationally connected with the air duct 3, a rotary bearing one 26 and a sealing ring 27 are arranged between the inner surface of the cover plate 5 and the outer surface of the air duct 3, the sealing ring 27 is below the rotary bearing one 26, the arrangement of the rotary bearing one 26 further ensures the smoothness and fluency of the rotation of the cover plate 5, and the sealing ring 27 can rotationally seal the gap between the cover plate 5 and the air duct 3 to prevent the airflow in the air duct 3 from blowing out of the gap and affecting the normal air volume in the air duct 3, the first driving part 6 is arranged on the cover plate 5 and is used for driving the cover plate 5 to rotate, and at least one first air blowing cylinder 7 is arranged at the top edge of the cover plate 5, and in the embodiment, two first air blowing cylinders 7 are arranged.

[0064] Further, the two through holes 12 are arranged oppositely.

[0065] When the air duct 8 rotates by 180 degrees, the blown airflow has rotated one circle, and under the same rotation speed, the air volume blown to the wire coil 4 is increased, thereby further improving the cooling effect of the wire coil 4.
