Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
As shown in fig. 1 to 3, an embodiment of the present invention provides a leveling machine roll wiping dust removing apparatus 1 including a wiping roller 11 adapted to wipe a roll 2 and a dust suction member 12; the dust collection member 12 is disposed near the wiping roller 11 and downstream of the wiping roller 11 in the running direction of the strip steel, and the dust collection member 12 adopts an electromagnet or incorporates an electromagnet.
The wiping roller 11 may be constructed using a conventional wiping roller 11, which is mainly used for wiping off dirt adhering to the roll 2. The suction member 12 is arranged downstream of the wiping roller 11, i.e. when the wiping roller 11 is in contact with the nip roller 2, the suction member 12 is located on the side of the wiping roller 11 remote from the nip roller 2.
Preferably, the dust collection member 12 is a roller member, that is, the dust collection member 12 is a dust collection roller, and an electromagnet is disposed in the roller correspondingly; the dust collection roller can rotate preferably so that all roller surfaces can absorb dust, and the electromagnet in the roller is preferably an annular electromagnet, so that the adsorbate can be firmly absorbed on the roller surfaces of the dust collection roller. The dust collection member 12 may be formed of other structural members, such as a plate member.
When the electromagnet is electrified, magnetic attraction can be given to the dust collection member 12, and magnetic dirt wiped by the wiping roller 11, magnetic dust around the dust collection member 12, iron scales and the like can be captured by the dust collection member 12; when the electromagnet is de-energized, the suction member 12 loses its suction of the adsorbates thereon, which can be readily removed from the suction member 12 to allow the suction member 12 to be reused. In one of the embodiments, as shown in fig. 1 and 2, the leveling machine roll wiping dust collector 1 further comprises a driving mechanism for driving the dust collection member 12 between a dust collection position and a dust removal position, in which dust collection bin 13 for collecting adsorbate on the dust collection member 12 is arranged. The dust collection box 13 is arranged at a place far away from the dust collection position, so that equipment is convenient to arrange, and meanwhile, when the dust collection member 12 performs dust collection work, dust in the dust collection box 13 cannot be adsorbed.
Preferably, the driving mechanism drives the dust collection member 12 to perform linear motion, so that the dust collection member 12 can be switched between a dust collection position and a dust removal position, and conventional linear driving devices such as an air cylinder, a hydraulic cylinder and the like can be adopted as the driving mechanism. In an alternative solution, the wiping roller 11 and the dust collection member 12 are arranged on the same mounting frame, and the driving mechanism is connected with the mounting frame, that is, the driving mechanism can enable the wiping roller 11 and the dust collection member 12 to synchronously move, so that on one hand, the arrangement of equipment is facilitated, the number of driving equipment is reduced, and more importantly, the relative position relationship between the wiping roller 11 and the dust collection member 12 can be kept stable, and therefore a reliable dust collection effect is ensured. In other embodiments, the dust collection member 12 is independently driven by a driving mechanism, so that the position of the dust collection member 12 can be flexibly adjusted according to specific working conditions to achieve optimal dust collection effect and efficiency.
Preferably, as shown in fig. 1 and 2, the dust collection box 13 includes a box body 131 and a box cover 132, wherein the box cover 132 is movably disposed on the box body 131 and has an open position and a closed position, and in the open position, the driving mechanism can drive the dust collection member 12 to move into the box body 131 or directly above the box body 131. Preferably, the dust collection member 12 is driven to move to the box 131, so that dust can fall into the box 131 completely; taking a dust collection roller as an example, the bearing seats at the two ends of the dust collection roller can be respectively connected with a set of linear driving device, so that the roller body of the dust collection roller can freely enter the box body 131, and the driving mechanism cannot interfere with the box body 131 or the box cover 132. The cover 132 may be an arc plate, which swings with respect to the case 131, so as to be opened or closed on the case 131; other hinge structures are also suitable for use in this embodiment. The case 131 and the case cover 132 are made of a material having no ferromagnetic property, for example, austenitic stainless steel or plastic.
Further, a dust scraping structure for scraping the adsorbate on the surface of the dust collection member 12 is provided on the dust collection member 12 or the dust collection box 13. The dust scraping structure can adopt scraping plates and the like, and driving equipment is correspondingly configured; the dust scraping structure can be arranged on the mounting frame, and when the dust collection component 12 is independently driven, the dust scraping structure can be arranged on the corresponding bracket.
Further optimizing the leveling machine roller wiping dust collector 1, the rotation direction of the wiping roller 11 is the same as the rotation direction of the corresponding roller 2, namely, the wiping roller 11 and the corresponding roller 2 rotate clockwise or anticlockwise. As shown in fig. 1 and 3, basically, a first air flow 41 can be formed on the outlet side of the temper mill by rotating the roller 2, and a second air flow 42 can be formed on the outlet side of the temper mill by running the strip steel 3, and the moving directions of the first air flow 41 and the second air flow 42 are basically outwards of the stand and simultaneously upwards; when the wiping roller 11 and the roller 2 rotate relatively, at the contact position of the two roller surfaces, the movement directions of the two roller surfaces are basically opposite, the rotation of the wiping roller 11 can provide an acting force for the first air flow 41 carried by the roller 2, the first air flow 41 is pressed down and driven to the downstream side, and the first air flow 41 finally flows to the dust collection component 12; the second air flow 42 formed by the running of the strip steel 3 can be captured by the dust collection component 12 during the rising process; therefore, in the embodiment, the directional guide of the air flow field at the outlet side of the leveling machine can be formed, and the dust removal effect is improved. The wiping roller 11 rotates in the same direction as the counter roller 2, and the wiping effect can be improved.
Correspondingly, the embodiment of the invention also relates to a leveling machine dust removal method based on the leveling machine roller wiping dust removal device 1, which comprises the following steps:
bringing the wiping roller 11 into contact with the roll 2 to wipe off dirt adhering to the roll 2;
based on the rotation motion of the roller 2, the strip steel running belt and the rotation motion of the wiping roller 11, an air flow field is formed at the outlet side of the leveling machine, solid waste is guided to the dust collection member 12 through the air flow field, and the dirt wiped by the wiping roller 11 and the solid waste carried by the air flow field are adsorbed by the magnetism of the dust collection member 12, wherein the solid waste comprises dust and iron oxide scale.
Wherein, as described above, when the direction of rotation of the wiping roller 11 and the roll 2 is the same, a better dust removing effect can be obtained.
Further, the dust collection member 12 is located closer to the strip running path than the wiping roller 11, except downstream of the wiping roller 11, and the dust collection member 12 is located on the side of the wiping roller axis closer to the strip running path, taking the dust collection roller as an example, the dust collection roller axis can make it easier for the dust collection member 12 to catch the air flow. In one embodiment, the included angle between the plane of the wiping roller axis and the dust collecting roller axis and the strip steel running channel is 28-48 degrees, wherein the effect is better at 40-45 degrees.
In addition, by setting and adjusting the position of the wiping roller 11, a better air flow guiding effect can be achieved, in particular: the axis of the wiping roller and the axis of the corresponding roller can be positioned in the same horizontal plane, or the height difference between the wiping roller and the axis of the corresponding roller is within 80 mm; or the roller diameter of the roller is R, and the height difference between the axis of the wiping roller and the strip steel running channel is in the range of 0.3R-0.6R.
Further preferably, the electromagnet adopted by the dust collection member 12 has adjustable magnetic force, and the magnetic attraction force of the dust collection member 12 can be adjusted according to specific working conditions, so that better dust collection effect and energy conservation are achieved.
