Detailed Description

As shown in fig. 1 to 5, a scrap steel cleaning roller comprises a feeding hopper 1, a roller 2, a dust removal device and a power device, wherein the roller 2 is horizontally arranged, the feeding hopper 1 is used for feeding the roller 2, the power device is used for driving the roller 2 to rotate, the dust removal device is used for absorbing impurities in the roller 2, specifically, the scrap steel cleaning roller further comprises a feeding buffer 3 and a discharging buffer 10, the outlet end of the feeding hopper 1 is connected with the inlet end of the feeding buffer 3, the outlet end of the feeding buffer 3 is rotationally connected with the inlet end of the roller 2, and the inlet end of the discharging buffer 10 is rotationally connected with the outlet end of the roller 2. The power device is used for driving the roller 2 to rotate forwards or backwards. The feeding buffer 3 and the discharging buffer 10 are both provided with dust removing openings, the dust removing openings are connected with the inlet end of a dust removing device, and the dust removing device is a dust collecting mechanism. When the roller 2 rotates, the steel material in the roller 2 can rotate along with the roller 2, the steel material in the roller 2 rubs mutually to scrape impurities such as silt on the steel material, and because the weight of the silt is very light, under the action of strong suction of the dust removal device, the silt is sucked into the feeding buffer 3 and the discharging buffer 10 from the roller 2 and then sucked out from the dust removal port, so that the cleaning of the steel material is realized. The inner wall of the roller 2 is provided with a guide rail 13, the guide rail 13 is obliquely arranged relative to the horizontal direction, the length of the guide rail 13 is matched with that of the roller 2, and specifically, the length of the guide rail 13 is equal to or slightly smaller than the length L of the roller 2. The guide rails 13 are multiple, the guide rails 13 are distributed at intervals along the circumferential direction of the roller 2, the inclined guide rails 13 are distributed at intervals to form a spiral conveying channel, and when the rotating direction of the roller 2 is the same as the spiral direction, the conveying of the scrap steel in the roller 2 can be realized. Moreover, when the roller 2 rotates reversely for cleaning, the guide rail 13 on the inner wall of the roller 2 can also play a role of stirring the steel material in the roller 2, and further increase the friction of the steel material in the roller 2. The cross section of the guide rail 13 is an I-shaped section. When the roller 2 rotates for cleaning, the guide rail 13 with the I-shaped section can play a role in stirring the steel materials, and meanwhile, the guide rail surface of one side, away from the roller wall, of the guide rail 13 can also play a role in hooking, so that the steel materials gathered together by rolling are dispersed, the friction between the steel materials is further increased, and the cleaning effect is improved.

The inclined angle of the guide rail 13 and the horizontal direction is 2-5 degrees. Specifically, when the rotation direction of the roller 2 is the same as the spiral direction of the spiral conveying channel, at the moment, along with the rotation of the roller 2, the steel material is conveyed to the outlet end along the spiral conveying channel to be automatically discharged, and when the rotation direction of the roller 2 is opposite to the spiral direction of the spiral conveying channel formed by the guide rail 13, at the moment, along with the rotation of the roller 2, the steel material is reversely conveyed, but the steel material cannot be output from the outlet end of the roller 2 due to the blocking effect of the feeding hopper 1, so that the steel material continuously rubs in the roller 2 to be cleaned. Therefore, the roller 2 needs to rotate forwards and reversely during operation, and although the conveying of the steel materials during discharging can be better realized through a larger spiral angle, the reverse conveying of the steel materials during cleaning is inevitably caused, and the steel materials are jammed at the inlet end of the roller 2. And the adoption of the 2-5 degree inclined angle can realize the automatic discharging during discharging and also avoid the blockage of the inlet end caused by the accumulation of the steel materials at the inlet end of the roller 2 due to the reverse conveying during cleaning.

The inner wall of the outlet end of the roller 2 is also provided with 2 arc guide plates 14, the arc guide plates 14 are obliquely arranged relative to the horizontal direction, and the arc guide plates 14 are staggered by 180 degrees. Further preferably, the arc-shaped guide plate 14 is inclined in the same direction as the guide rail 13. The arc-shaped guide plates 14 are arranged to assist the discharge of the steel material. The 2 arc-shaped guide plates 14 arranged in a staggered mode can also form a spiral channel with the spiral direction the same as that of the spiral conveying channel formed by the guide rails 13, and when the steel materials are discharged, the steel materials are conveyed to the outlet end of the roller 2 by the guide rails 13 and are discharged out of the roller 2 along the spiral channel at the outlet end.

The roller 2 is further internally provided with a plurality of fins 15, the fins 15 are obliquely arranged relative to the horizontal direction, the oblique direction of the fins 15 is the same as that of the guide rail 13, and the plurality of fins 15 are arranged along the circumferential direction of the roller 2. Further preferably, the fins 15 are distributed in a staggered manner with respect to the guide rails 13. Set up fin 15 in the cylinder 2 can further increase the stirring of the interior steel material of cylinder 2, increase the friction between the steel material, increase the edulcoration effect. And the fins 15 and the guide rails 13 adopt the same inclined direction, so that the fins 15 and the guide rails 13 can form the same spiral conveying track during discharging, and the conveying capacity of the guide rails 13 is increased.

The cross section of the fin 15 is an i-shaped section. The fins 15 with the I-shaped cross sections can stir steel materials, and simultaneously the fin surfaces of the sides, far away from the drum wall, of the fins 15 can also play a role in hooking.

The power device comprises a motor 6, a speed reducer 7 and a driving gear 8 which are sequentially connected, an annular rail 9 is arranged on the outer wall of the roller 2, a plurality of gear teeth are arranged on the annular rail 9, and the driving gear 8 is meshed with the gear teeth. Motor 6 passes through speed reducer 7 drive gear 8 and rotates, and drive gear 8 and the gear tooth on the cylinder 2 mesh, and then realize that drive gear 8 drives gear tooth and rotates to realize that motor 6 drives cylinder 2 and rotates.

The scrap steel cleaning roller is further provided with a roller support frame 5, a tugboat 11 is arranged on the roller support frame 5, an annular sliding ring 4 is arranged on the outer wall of the roller 2, and the annular sliding ring 4 is matched with the tugboat 11 for use. When the roller 2 rotates, the roller 2 drives the annular sliding ring 4 to rotate, the annular sliding ring 4 rotates to further drive the tug 11 to rotate, the annular sliding ring 4 is in rolling contact with the tug 11, and then the roller support frame 5 is used for supporting the roller 2.

The roller support frame is also provided with two

catch wheels

12, and 2 catch wheels 12 are respectively arranged at two sides of the annular sliding ring 4. The blocking wheels 12 arranged on the two sides of the annular sliding ring 4 can limit the annular sliding ring 4 to move towards the two sides, so that the movement of the roller 2 is limited, and the stability of the scrap steel cleaning roller during working is ensured.
