[0028] The following is a detailed description of a dust removal device for steel provided by the utility model.

[0029] like Figure 1 As shown, a dust removal device for steel includes the bracket, hose 13, and air duct 14 mentioned in the above embodiment.

[0030] The air duct 14 provides the air source for the dust removal device. It is connected to the hose 13 via a connector 15. The hose 13 is connected to a bracket, and an air coil 2 is located on the upper portion of the bracket to remove dust from the steel. In other words, the air duct 14 sequentially connects to the connector 15, the hose 13, and the bracket's air coil 2, providing the air source for the air coil 2 and, in turn, removing dust from the steel. A wind switch is installed on the air duct 14 to control the on / off of the air source, as well as the air volume and speed. The wind switch can be mechanical or electronic, preferably electronic. Before inspecting the steel, turning on the wind switch automatically blows air to remove dust. The air duct 14 outputs one or more ventilation channels; for example, channels 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. Each ventilation channel is connected to a hose 13 via a connector 15, and each ventilation channel can be individually controlled.

[0031] In one embodiment, each connector 15 controls one ventilation channel; in another embodiment, the on / off state, air volume, and wind speed of each ventilation channel are controlled by the wind switch.

[0032] The air duct 14 is connected to the bracket through a hose 13. The bracket is columnar and is used to provide support for the dust removal device. An air coil 2 is provided on the upper part of the bracket. The air coil 2 is used to remove dust from the steel, that is, to provide dust removal at multiple angles. The air coil 2 is fixedly mounted on the upper part of the bracket. The cross-sectional shape of the air coil 2 can be circular, annular or elliptical. Preferably, the cross-sectional shape of the air coil 2 is annular. A dust blowing gun barrel is provided on the air coil 2. The dust blowing gun barrel is arranged along the circumference of the air coil 2. The dust blowing gun barrel further enhances the dust removal power of the dust removal device. Preferably, the dust blowing gun barrels are evenly arranged along the circumference of the air coil 2. The dust blowing gun barrels are connected to the air duct 14 through a hose 13. The air duct 14 provides a wind source for the dust blowing gun barrel.

[0033] In one embodiment, a pressurizing device is installed within the dust blower tube to enhance the dust removal power of the dust removal device. In another embodiment, each dust blower tube is equipped with a tube switch to independently control the on / off function, air volume, and air velocity of each dust blower tube. There are one or more dust blower tubes, and the number of dust blower tubes corresponds to the number of hoses 13. In other words, there is a one-to-one correspondence between the dust blower tubes, hoses 13, connectors 15, and ventilation ducts.

[0034] A nozzle 21 is provided at the end of each dust blowing gun tube, that is, the nozzle 21 is provided along the circumference of the wind circle 2. Preferably, the nozzle 21 is evenly provided along the circumference of the wind circle 2. The nozzle 21 blows out wind to remove dust from the steel. There are one or more nozzles 21, and the number of nozzles 21 corresponds to the number of dust blowing gun tubes; preferably, there are 8 nozzles 21. In one specific embodiment, each nozzle 21 is provided with a nozzle switch, and each nozzle 21 can independently control the on / off of the nozzle 21 and the size of the air volume and wind speed. In another specific embodiment, the on / off and the size of the air volume and wind speed of each nozzle 21 are controlled by the nozzle switch.

[0035] Multiple nozzles 21 arranged along the circumference of the air ring 2 form a nozzle circle, which is positioned over the outside of the steel to remove dust from the steel. The nozzle circle has a diameter of 200mm, larger than the maximum diameter of the steel of 130mm. During operation, air from the air duct 14 passes through the hose 13 and the dust blower barrel, exiting the nozzles 21 to purge and remove dust from the steel, achieving full coverage of steel sizes from 50 to 130mm.

[0036] Before flaw detection, the wind circle 2 (that is, the nozzle circle) is set at a set first angle with the central axis of the steel, that is, multiple dust removal directions are provided. The range of the first angle is 20-60°, for example, 20, 30, 40, 45, 50, 60°. Preferably, the wind circle 2 (that is, the nozzle circle) is set at a 45° angle with the central axis of the steel, and this angle has a good blowing and dust removal effect.

[0037] The bracket includes a support rod 11, which is used to support the wind circle 2. The support rod 11 is columnar or tubular and is arranged below the wind circle 2. Preferably, the support rod 11 is in the shape of a circular tube, and the support rod 11 and the wind circle 2 are fixedly connected; specifically, the support rod 11 and the wind circle 2 can be snapped, screwed or welded. Preferably, the support rod 11 and the wind circle 2 are welded and fixed; the axis of the support rod 11 is perpendicular to the axis of the wind circle 2. The height of the support rod 11 can be fixed, and of course the height of the support rod 11 can also be adjusted, such as a plug-in rod, a telescopic rod, or a parent-child rod. The height of the support rod 11 can be adjusted according to the height of the steel to facilitate dust removal; the adjustment method can be manual or electric. Preferably, the support rod 11 is provided with one.

[0038] In a specific embodiment, the support rod 11 is a telescopic rod, and the height of the telescopic rod is adjusted by electric adjustment. The support rod 11 also includes a telescopic rod remote controller for remotely adjusting the height of the electric telescopic rod.

[0039] The bracket also includes a support leg 12, which is arranged below the support rod 11 and is used to support the support rod 11. The support leg 12 can be fixedly connected to the support rod 11. Of course, the support leg 12 and the support rod 11 can also be movably connected, such as a support leg 12 similar to a music stand structure. In order to provide firm support, a plurality of support legs 12 can be provided, such as 3, 4, or 5; each support leg 12 and the support rod 11 above the support leg 12 can be arranged at a set second angle, and the second angle is greater than 90°.

[0040] In one embodiment, the second angle is in a range of 92-170°, such as 92, 95, 97, 100, 105, 110, 120, 130, 140, 150, 160, or 170°. The second angle is adjustable.

[0041] In a specific embodiment, the bottom of the legs 12 is provided with wheels, which contact the ground for easy movement of the support. A fixture can be provided on each wheel to lock the wheel and prevent it from rolling.

[0042] In an optional embodiment, a motor may be provided on the wheel to electrically drive the wheel to rotate; further, the wheel may also be provided with a wheel remote controller to control the moving direction and speed of the wheel, thereby remotely controlling the dust removal device to remove dust from the steel.

[0043] A flaw detection device for steel includes the dust removal device and flaw detection equipment mentioned in the above embodiment. The dust removal device is arranged upstream of the flaw detection equipment. That is, before the flaw detection equipment is used, the dust removal device is first used to remove dust, and then the flaw detection equipment is used to detect flaws in the steel.

[0044] The present application provides a dust removal device for steel, which uses an air duct 14 to remove dust, effectively preventing dust and easily detached oxide scale from accumulating and entering the main body of the flaw detection equipment, protecting the probe of the flaw detection equipment from being worn by foreign objects, ensuring the flaw detection accuracy of the probe and increasing the service life of the probe. The dust removal device can quickly remove dust from the surface of the steel, ensuring that the steel surface is clean and ready for flaw detection.
