Technical Field
[0001] The utility model relates to the cooling of hot-rolled high-speed wire in the iron and steel industry, and is particularly applicable to the ventilation equipment for cooling wire rods, bars and plates on hot-rolled high-speed wires. Background Art
[0002] In the environment of energy conservation and consumption reduction, the market competition in the iron and steel manufacturing industry is becoming increasingly fierce. In the early stage, most of the fans used for cooling hot-rolled high-speed wires in the iron and steel industry were centrifugal ventilators, which were equipped with bearing boxes and bearing water-cooling systems, and the structure was too complex; both the mechanical part of the bearing box and the bearing water-cooling power system generated large energy losses, resulting in an increase in motor power consumption; at the same time, the use of centrifugal ventilators not only wasted water resources but also occupied a large area. Content of the Utility Model
[0003] The utility model aims to overcome the above technical defects and provides an axial flow fan for controlled cooling of high-speed wires with a simple structure, low power consumption and small floor area.
[0004] To achieve the above object, the technical solution adopted by the utility model is: it is composed of a protective net (1), a cylinder body (2), high-strength bolts (3), a motor (4), a support screw group (5), an adjustment tie rod group (6), a flexible connection (7), an inclined base (8), a shock absorber (9), and an axial flow impeller (10). The characteristics are that the motor (4) is locked and installed on the guide vane inner cylinder (2b) through high-strength bolts (3), the motor (4) is supported and installed between the cylinder body (2) through the support screw group (5), the motor (4) shaft head is in the center position of the cylinder body (2) through the adjustment tie rod group (6), the axial flow impeller (10) is installed on the motor (4) shaft head, a protective net (1) is arranged at the inlet of the cylinder body (2), a flexible connection (7) is arranged at the outlet of the cylinder body (2), the cylinder body (2) is installed on the inclined base (8) and is positioned and fixed by bolts through a stop block (8a), and 6 shock absorbers (9) are arranged on the inclined base (8).
[0005] Adopting the above technical solution, compared with the centrifugal ventilator used for cooling hot-rolled high-speed wires in the early iron and steel industry, the utility model has the characteristics of simple structure, low power consumption and small floor area.

[0008] The following further describes the present utility model in conjunction with the attached drawings, which is not a limitation of its protection scope.
[0009] A high-speed wire controlled cooling axial flow fan is composed of a protective net (1), a cylinder body (2), high-strength bolts (3), a motor (4), a support screw group (5), an adjustment pull rod group (6), a flexible connection (7), an inclined base (8), a shock absorber (9), and an axial flow impeller (10). It is characterized in that the motor (4) is locked and installed on the guide vane inner cylinder (2b) through high-strength bolts (3). The motor (4) is supported and installed between the cylinder body (2) through the support screw group (5). The motor (4) shaft head is positioned at the center of the cylinder body (2) through the adjustment pull rod group (6). The axial flow impeller (10) is installed on the shaft head of the motor (4). A protective net (1) is provided at the inlet of the cylinder body (2), and a flexible connection (7) is provided at the outlet of the cylinder body (2). The cylinder body (2) is installed on the inclined base (8) and is positioned and fixed by bolts through a stop block (8a). Six shock absorbers (9) are provided on the inclined base (8). Its overall structure is simple and the installation and assembly are convenient. The present utility model directly drives the axial flow impeller (10) by the motor (4), which greatly reduces the mechanical loss during the transmission process. The cooling air formed by the rotation of the axial flow impeller (10) cools the motor (4) and the bearings, and there is no need to set up a water cooling system. Compared with the centrifugal ventilator used for cooling the hot-rolled high-speed wire in the early steel industry, the shaft power loss is reduced by at least 18.5%, and it has a good energy-saving effect. The overall installation structure of the inclined base (8) discharges air obliquely upwards at 45°, directly saving the duct elbow material at the outlet of the fan, which not only saves costs but also reduces the floor area of the equipment.
[0010] A high-speed wire controlled cooling axial flow fan is characterized in that a sound-absorbing cotton (2a), a guide vane inner cylinder (2b), and a flow guiding orifice plate (2c) are arranged inside the cylinder body (2); the guide vane inner cylinder (2b) is welded to the cylinder body (2), and the sound-absorbing cotton (2a) is filled between the flow guiding orifice plate (2c) and the outer shell of the cylinder body (2). By adopting the above cylinder body (2) structure scheme, the overall rigidity of the fan is improved. The sound-absorbing cotton (2a) filled between the flow guiding orifice plate (2c) and the outer shell of the cylinder body (2) has the functions of noise reduction and reduction of turbulence, ensuring that the fan operates at high efficiency and low noise.
[0011] Therefore, the present utility model is a high-speed wire controlled cooling axial flow fan with a simple structure, low power consumption, and small floor area.
