[0002] When resin sand is used in casting production, the used resin sand needs to be recycled. However, during the recycling process, the resin sand will be mixed with metal debris from the casting, which needs to be removed. For this purpose, recycling magnetic separation equipment will be used.

[0003] During use of the existing resin sand recovery magnetic separation equipment, the resin sand is driven through the equipment by a fluid, and the metal slag is adsorbed and taken out by a magnetic roller, thereby performing magnetic separation. However, during the use of the equipment, the particle size of the metal slag is uneven. When the metal slag with larger particles is magnetically separated, it is easy to cause the magnetic separation channel to be blocked, thereby affecting the magnetic separation of the resin sand. For this reason, the utility model proposes a resin sand recovery magnetic separation equipment. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7The utility model provides a technical solution of resin sand recovery magnetic separation equipment: a resin sand recovery magnetic separation equipment, including an equipment bracket 1, a drum 2, a driving motor 3 and a transmission mechanism 4, and also includes: a support shaft 5, the support shaft 5 is located in the middle of the drum 2, and the outer side of the equipment bracket 1 is provided with a second bearing seat connected to the support shaft 5, the top of the support shaft 5 is installed with a connecting frame 6, and the bottom of the connecting frame 6 is fixedly connected with a plurality of groups of magnet blocks 7; a feed hopper 8, the feed hopper 8 is fixedly connected to the equipment bracket 1, and the inside of the feed hopper 8 is provided with a feeding channel 9, a feeding channel 10, a magnetic separation channel 11, a discharging hole 12 and a discharging channel 13, and the other side of the feed hopper 8 is provided with a metal debris collection channel 14; a filter component 17, the filter component 17 is installed on the top of the feed hopper 8, and large debris can be filtered.

[0031] In addition, the water pipe 15 used is connected to the external water supply pipe, and a plurality of groups of nozzles 16 are fixedly connected to the outside of the water pipe 15. The plurality of groups of nozzles 16 are connected to the water pipe 15, and the opening of the nozzle 16 faces one side of the drum 2, so as to facilitate the removal of metal debris and pour it into the metal debris collection channel 14, so as to facilitate the collection of the debris.

[0032] Among them, the filter assembly 17 includes a rotating shaft 171, a filter screen plate 172 fixed on one side of the rotating shaft 171, a first bearing seat 173 and a connecting box 174 at the end of the rotating shaft 171, a rotating motor 175 outside the connecting box 174, a connecting shaft 176 and a driving gear 177 at the output end of the rotating motor 175, a driven gear 178 and a limit plate 179 outside the rotating shaft 171, a mounting frame 1710 inside the connecting box 174, and a limit switch 1711 at the upper end of the mounting frame 1710, the rotating shaft 171 and the driven gear 178 are fixedly connected, the output end of the rotating motor 175 and the connecting shaft 176 are fixedly connected, the driving gear 177 and the driven gear 178 are meshed, the rotating motor 175 and the limit switch 1711 are electrically connected to the external controller, and large debris can be filtered and dumped.

[0033] Furthermore, the number of anti-sedimentation components 18 is three groups and they are distributed in an array at the bottom of the feed hopper 8. The anti-sedimentation components 18 include a stirring motor 181, a stirring shaft 182 fixed at the output end of the stirring motor 181, and two groups of stirring rods 183 fixed on the outside of the stirring shaft 182. The fluid inside the discharge channel 9 can be stirred with the resin sand to avoid sedimentation.

[0034] The resin sand recovery magnetic separation equipment, during operation, pours fluid and resin sand into the interior of the feed hopper 8 at the same time, filters and dumps large debris through the filter assembly 17, and then enters the magnetic separation channel 11 through the unloading channel 9 and the loading channel 10, and then drives the drum 2 to rotate through the output end of the driving motor 3 and the transmission mechanism 4, so that the bottom of the drum 2 close to the magnet block 7 generates magnetic force, and the metal debris inside the magnetic separation channel 11 is adsorbed on the outside of the drum 2. During the continuous rotation of the drum 2, the debris away from the magnet block 7 will be sprayed with water through the nozzle 16, which will drive the metal debris to fall into the metal debris collection channel 14, thereby repeatedly running to conduct the magnetism of the resin sand, and at the same time, the resin sand will enter the interior of the discharge channel 13 through the discharge hole 12, so as to be discharged externally, and the internal metal debris will be magnetically separated, thereby improving the magnetic separation efficiency.

[0035] It should be noted that, through the setting of the filter assembly 17, when the resin sand is filtered, it is filtered through the filter plate 172. When large debris needs to be removed, the connecting shaft 176 and the driving gear 177 are driven by the output end of the rotating motor 175, so that the driving gear 177 and the driven gear 178 are meshed, and the driven gear 178 drives the limit plate 179 to rotate, and then drives the rotating shaft 171 and the filter plate 172 to rotate, so that the filter plate 172 is reversed until the limit plate 179 contacts the limit switch 1711 at the upper end of the driving gear 177, thereby feeding back to the external controller, controlling the output end of the rotating motor 175 to reverse, and resetting the filter plate 172, thereby reversing the filter plate 172 and cleaning the large debris at the upper end, facilitating subsequent debris filtering, and further avoiding blockage in the magnetic separation channel 11.

[0036] It should be noted that through the setting of the anti-sedimentation component 18, when magnetic separation is carried out inside the feed hopper 8, the output end of the stirring motor 181 is controlled by an external controller to drive the stirring shaft 182 and the stirring rod 183 to rotate, thereby stirring the fluid inside the discharge channel 9 with the resin sand to prevent its sedimentation.
