In the embodiment of the present invention as shown in fig. 1 to 11, there is provided a steel shot slag magnetic separation device for separating steel shots, comprising: the magnetic separation assembly comprises a magnetic system 1, a conveying ring 2 sleeved outside the magnetic system 1 and a first driving piece driving the conveying ring 2 to rotate around a set axis, wherein a plurality of rows of fixing holes 3 are formed in the outer surface of the conveying ring 2 along the rotating direction of the conveying ring;
the blanking hopper comprises a hopper body 4 and shot dropping pieces 5 arranged on the lower side of the hopper body 4, wherein the shot dropping pieces 5 are provided with a plurality of shot dropping holes 6 at intervals along a set axis, when the fixed holes 3 rotate to the lower sides of the shot dropping holes 6, the shot dropping holes 6 respectively correspond to one fixed hole 3, a limiting piece is arranged on the edge of one side of the shot dropping hole 6 in the rotating direction of the conveying ring 2, the distance between the limiting piece and the outer surface of the conveying ring 2 is smaller than the diameter of a steel shot, and the distance between the limiting piece and the bottom of the fixed hole 3 is larger than or equal to the diameter of the steel shot, so that when the fixed holes 3 rotate to the lower sides of the shot dropping holes 6, the conveying ring 2 can drive the steel shot to pass through the lower sides of the limiting piece;
the shielding belt 7 covers the conveying ring 2 at the fixing hole 3, at least part of the shielding belt 7 covers one side of the fixing hole 3 departing from the rotating direction of the conveying ring 2, and a through hole 8 is formed in the bottom of the fixing hole 3 of the shielding belt 7;
lead the shot subassembly, install one side of magnetic separation subassembly is including having the second driving piece that leads shot piece 10, drive of leading shot chamber 9 lead the second driving piece that shot piece 10 removed, the second driving piece can drive lead shot piece 10 and be close to carry the ring 2 the primary importance and keep away from carry and move between the ring 2 the secondary importance, when leading shot piece 10 and being located the primary importance, lead the tip of shot piece 10 with distance between 3 bottoms of fixed orifices is less than the diameter of shot, so that shot in the fixed orifices 3, when leading shot piece 10 and being located the secondary importance, lead the tip of shot piece 10 with the distance between the ring 2 surfaces of transport is greater than the diameter of shot.
When the separating device is used, materials mixed with steel shots and slag enter the hopper body 4 and enter the shot falling holes 6 of the shot falling piece 5. Due to the limitation of the limiting part, for relatively complete steel shots (the maximum radial dimension of the steel shots is larger than the distance between the limiting part and the outer surface of the conveying ring 2), when the fixing hole 3 is not rotated to the shot falling hole 6, the steel shots stay in the shot falling hole 6, the fixing hole 3 is rotated to the shot falling hole 6, the steel shots fall into the fixing hole 3, and the shielding belt 7 is arranged in the through hole 8 at the bottom of the fixing hole 3, so that the steel shots are magnetically absorbed at the fixing hole 3, the limiting part loses the limitation on the steel shots, and the steel shots rotate along with the conveying ring 2.
For steel shots with smaller grain diameter than the steel shots and serious damage (the maximum radial dimension of the steel shots is smaller than the distance between the limiting part and the outer surface of the conveying ring 2), the limiting part can not limit the materials, so that the materials can freely fall from the shot falling hole 6, and when the materials still exist in the shot falling hole 6 after the fixed hole 3 rotates, the materials are adsorbed at the position between two rows of the fixed holes 3 on the conveying ring 2 until the next complete steel shot moves to the shot falling hole 6. Moreover, because the conveying ring 2 has a certain distance between the two rows of fixing holes 3, after some steel shots with serious damage are limited by the limiting part, the part of the conveying ring 2 between the two rows of fixing holes 3 drives the steel shots with serious damage at the limiting part to rotate when rotating, and the steel shots with serious damage are adsorbed on the surface of the conveying ring after rotating to be lower than the limiting part and are taken away by the conveying ring.
When the fixed orifices 3 move to the position of the shot guiding assembly, the second driving piece drives the shot guiding piece 10 to move from the second position to the first position, so that the steel shots in the fixed orifices 3 can enter the shot guiding cavity 9, at the moment, the conveying ring 2 further rotates, so that the more complete steel shots are separated from the bottom of the fixed orifices 3, the steel shots completely move to the shielding belt 7 and then roll in the further shot guiding cavity 9, and further the steel shots in the fixed orifices 3 are guided away by the shot guiding piece 10. After the fixing opening 3 has been rotated past the position of the pill guiding member 10, the pill guiding member 10 is moved from the first position back to the second position.
For the slag and steel shot sucked on the surface of the conveying ring 2 and between the two rows of fixing holes 3, as shown in fig. 6, the slag and steel shot automatically drop when the conveying ring 2 rotates past the position of the lower side of the magnet system 1. Thereby completing the separation of the relatively complete steel shot.
According to the process, the steel shots and the slag are sequentially dropped through the shot dropping hole 6 of the shot dropping piece 5, and the complete steel shots are dropped into the fixing hole 3 through the matching of the limiting piece and the fixing hole 3, so that the complete steel shots can be conveniently guided and shunted by the subsequent shot guiding piece 10; meanwhile, the part of the conveying ring 2 between the two rows of fixing holes 3 is magnetically attracted to broken slag and steel shots which are seriously broken, so that the materials are reduced from being mixed with the steel shots at the fixing holes 3 again, and the separation effect is improved.
For the application of the present application, it should be noted that the improvement of the present application lies in the separation of metal slag (mainly aiming at ferrous slag capable of being magnetically attracted) and severely broken steel shots, and is not adaptively implemented for other types of mixed materials (non-magnetic slag, powder scraps), and the like, when other types of mixed materials are required to be contained, the separation device per se may be matched with the existing steel shot sorting mechanism, for example, a screening mechanism may be added in the process of the present application to sort the powder scraps, and a magnetic separation mechanism as exemplified in the background art may also be added in the process of the present application to separate the non-magnetic slag. The equipment can be applied to the shot blasting machine to form a part of the shot blasting machine equipment, and can also be used as independent equipment for screening the steel shots falling from the shot blasting machine. For the arrangement of the shielding tape, an existing magnetic shielding plate or magnetic shielding rubber can be preferably selected.
For the screening of the sorting integrity of the steel shots, it needs to be noted that the distance between the limiting part and the outer surface of the conveying ring 2 is used for controlling the particle size of the broken steel shots, preferably, the distance D1 between the limiting part and the outer surface of the conveying ring 2 is selected from the diameter of the steel shots of 0.7-0.9 times, at the moment, the smallest radial dimension of the broken part of the steel shots is larger than that of D1 and is used as the more complete steel shot to enter the shot guide cavity 9, the integrity of the steel shots is better, the probability that the broken part impacts the workpiece is relatively lower when the workpiece is hit again, and the probability of generating scratches is relatively lower. For the depth D2 of the fixation hole 3, D2 is selected from the group consisting of 0.1-0.3 times the diameter of the steel shot.
The arrangement of the first drive member may preferably be selected from a gear motor.
In the embodiment shown in fig. 1, the angle of wrap of the magnetic system 1 is preferably selected from 90-120 °, the upper edge of the magnetic system 1 extending to the left of the apex of the transport ring 2 and the lower edge of the magnetic system 1 extending to the lower side of the horizontal plane in which the centre of rotation of the transport ring 2 is located.
In the embodiment of the invention, it is further optimized that the surface of the limiting member is provided with an external thread 11. Through having set up the screw thread on the surface at the locating part, when the part that is located between two rows of fixed orificess 3 at conveying ring 2 is located 6 downside of shot that falls, conveying ring 2 rotates and to some extent can drive the shot that falls in the shot hole 6 and roll along conveying ring 2 direction of rotation, through having set up the external screw thread, the external screw thread can guide the shot to roll along setting for the axis synchronization, thereby increased the shot with the regional rotation of damage to directly up, probability directly under, to the minimum radial dimension is less than D1's shot after the damage, the probability of being reserved by the locating part has been reduced.
In the embodiment shown in fig. 1, the limiting member is, more specifically, the limiting member is a limiting roller 12 rotatably disposed on the pill dropping member 5, the limiting roller 12 extends along a set axis, and the external thread 11 is disposed on the outer surface of the limiting roller 12. As shown in fig. 2 and 3, the limiting member is provided as the limiting roller 12, so that rolling resistance and abrasion of the steel shot when the steel shot is driven to rotate by the conveying ring 2 can be reduced. As shown in fig. 2 and 3, the middle of the stopper roller 12 is concavely curved to conform to the spherical surface of the steel shot.
In the embodiment shown in fig. 11, the arrangement of the shielding strips 7 is further optimized in that the height of the shielding strips 7 on the side of the fixing holes 3 facing away from the rotation direction of the conveying ring 2 is gradually increased. As shown in fig. 11, the shielding tape 7 has a gradually increasing thickness, which facilitates the shot to enter the shot guiding chamber 9 after the shot is ejected from the fixing hole 3 by the shot guiding member 10. Further facilitating the falling of the steel shots from the conveying ring 2.
In the embodiment shown in fig. 1, with respect to the structure of the drop pill 5, more specifically, as shown in fig. 6, 7 and 8, the drop pill 5 is disposed obliquely downward toward the rotation direction of the conveying ring 2, so that the drop pill 5 has an inner cavity extending obliquely, and the drop pill 5 is provided at the bottom with a drop pill hole 6, the cross-sectional size of the drop pill hole 6 being larger than the diameter of one steel pill and smaller than the diameter of 1.5 steel pills. Through setting the falling shot piece 5 to the slope, can reduce the gravity that the steel shot transmission got off above the steel shot of 6 departments of falling shot hole, and then make the rotation of the steel shot of 6 departments of falling shot hole more smooth and easy, can reduce the wearing and tearing between steel shot and the transport ring 2 on the one hand, on the other hand can make damaged steel shot rotate easily to the locating part downside and pass through.
Regarding the structure of the drop pill 5, in the embodiment shown in fig. 1, further specifically, as shown in fig. 6, the drop pill 5 includes an upper plate and a lower plate, and a partition plate disposed between the upper plate and the lower plate, the partition plate dividing a space between the upper plate and the lower plate into inner chambers for dropping the steel shots.
