Specific implementation

[0023] Reference Figure 1 In the embodiment, an online steel billet surface oxide scale cleaning device for auxiliary inspection is disclosed, comprising a brush roller 5 installed above a roller 1 through a support 6, a high pressure water spray frame 4 installed above the roller 1, and a smoke cover 3 installed directly above the high pressure water spray frame 6; wherein a telescopic cylinder I 7 for adjusting the position of the brush roller 5 is symmetrically installed on the support 6, and the brush roller 5 is driven to rotate through a motor 8; wherein the position height is adjusted by means of the telescopic cylinder I 7 to clean the oxide scale on the billet of different thicknesses; the high pressure water spray frame 4 is connected with a water pump 42 through a high pressure water pipe 41; and the smoke cover 3 is connected with a dust removal system.

[0024] Reference Figure 2 The roller 1 is driven to transmit through a roller motor 11, and an infrared sensor 12 for detecting a billet 2 is installed on the axial end side of the roller 1.

[0025] Reference Figure 2 A plurality of high pressure nozzles connected with the high pressure water pipe 41 are installed on the high pressure water spray frame 4; the spraying direction of the high pressure nozzles is an acute angle with the conveying direction of the billet 2; wherein an electromagnetic valve is installed on the high pressure water pipe 41 to facilitate electromagnetic control of water spraying or closing.

[0026] Reference Figure 3 The smoke cover 3 comprises a prism-shaped cover body installed above the roller 1 through a support structure or a hoisting structure, and an air extraction pipe connected with the top of the prism-shaped cover body; wherein a conveying belt, specifically a high temperature resistant conveying belt, is installed on the bottom of the roller for collecting and transferring the oxide scale washed down.

[0027] When in use, when the billet 2 travels to the position sensed by the infrared sensor 12, the infrared sensor 12 transmits a signal to the high-pressure water pump 42, the high-pressure water pump 42 starts to spray water on the billet 2 through the high-pressure water spraying frame 4, and the brush roller 5 is used to flush the iron oxide that is not cleaned to the roller way below, and specifically to the conveying belt 13 and the reverse direction.

[0028] In addition, the position of the billet in line is identified by the infrared sensor, and when the billet advances to the fixed position, a signal is transmitted to the high-pressure water pump to provide water pressure. The high-pressure water nozzle sprays water on the surface of the billet by the pressure provided by the high-pressure water pump to blow and wash the iron oxide and other impurities on the surface of the billet. The brush roller is driven by the belt when the roller is driven by the motor below to provide power. When the brush roller rotates on the roller below, the belt provides a counteracting force to clean the iron oxide and other impurities on the surface of the billet. The smoke hood collects and processes a large amount of water vapor generated when the high-pressure water blows the surface of the billet.

The transmission chain 52 is meshed around the tension chain wheel 10, so that the transmission chain 52 around the chain wheel I 51, the chain wheel II 81 and the tension chain wheel 10 is in a taut state.

[0032] In use, when applied to steel billets 2 of different thicknesses, by simultaneously controlling the two telescopic cylinders I 7 to descend until the brush roller 5 can effectively clean the scale on the steel billets; at the same time, by telescoping the telescopic cylinder II 9, the roller shaft 91 is driven to slide in the transverse sliding groove 63, thereby driving the tensioning sprocket 10 to always keep the transmission chain 52 wound around the sprocket I 51 and the sprocket II 81 in a taut state, thereby facilitating the rotation of the transmission chain 52 driven by the motor 8 to drive the rotation of the brush roller 5.
