DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figures 1-5 A magnetic separation device in this embodiment includes a processing box 1 and a material feeding assembly connected to and on both sides of the processing box 1, and a material return assembly on the back of the processing box 1. The inner side of the processing box 1 is equipped with a material turning assembly, and the top is equipped with a water tank 29 and three magnetizing boxes 16. The front of the magnetizing box 16 is equipped with a switch valve 17 and the back is equipped with an arc-shaped inlet pipe 18, the pipe mouth of the inlet pipe 18 faces upward, the top of the water tank 29 is fixed with a heating box 26, the bottom of the heating box 16 is conical, and the heating box 2 A distribution box 27 is fixed at the bottom of 6, and the distribution box 27 is located above the water source of the water tank 29. A plurality of arc-shaped steel columns 30 arranged at equal distances are fixed on the inner side of the distribution box 27. Three conduits 28 connected to the arc-shaped steel columns 30 are fixed on the front side of the distribution box 27. The three conduits 28 extend into the water source of the water tank 29, and are penetrated by the water tank 29 and extend to the top of the pipe opening of the inlet pipe 18. An inlet pipe and an outlet pipe are installed on the outer side of the water tank 29, and the inlet pipe and the outlet pipe are connected to the external water source.

[0020] In the above structure, through the cooperation of the feeding component and the turning component, the crushed tires can enter from the left and exit from the right. After the magnetic charging box completes the magnetic charging of the steel balls, the switching valve opens, allowing the steel balls to fall into the turning component of the processing box and roll together. At the same time, it can evenly adsorb the iron components in the tires. When rolling for a period of time, through the turning component, the steel balls adsorbed with iron components can be placed under the bottom of the processing box, and then through the return component, the steel balls are transferred to the heating box. Through heating, the demagnetization of the steel balls is completed, separating the iron components from the steel balls. Then, through the opening and closing at the bottom of the heating box, they are introduced into the feeding box. At this time, the steel balls will be guided to the three conduits through the arc-shaped steel columns. Because there are gaps between the arc-shaped steel columns, the iron components fall to the bottom of the feeding box and are collected through the pipes at the bottom and then into the water tank. Then the steel balls enter the conduits, and the cooling of the steel balls is completed through the water source in the water tank. Then, they are guided to the magnetic charging box through the inlet pipe for magnetic charging, realizing the function of cyclic adsorption. At the same time, the water in the water tank can be made flowing water through the inlet pipe and the outlet pipe, improving the cooling effect.

[0021] As Figure 1 For the direction shown, the feeding component includes upper frames 12 located on the left and right sides of the processing box 1. At the top of the upper frames 12, there are fixed conveying cylinders 15 communicating with the processing box 1. On the frame body of the upper frames 12, there are fixed inclined plates 13. Both inclined plates 13 are inclined downward to the right. On the plate surface of the inclined plates 13, there are installed vibration motors 14. Through the inclined setting of the inclined plates and in cooperation with the vibration of the vibration motors, the gravity can be biased to the lower right, enabling the tires to enter the processing box to complete the feeding operation. At the same time, in cooperation with the turning component, the tires can be guided to the right feeding component, and through the vibration of the vibration motors, the processed tires can be sent away, thereby improving the conveying efficiency.

[0022] Among them, the buffer part includes a base 8 located below the upper frames 12. At the top of the base 8, there are fixed four vertical rods 9 passing through the upper frames 12. On the outer side of the vertical rods 9, there is a spring 11 located below the upper frames 12, and a nut 10 located above the upper frames 12 is threadedly connected to the top. By tightening the nut, the greater the force of the upper frame pressing down on the spring can be, and then through the vibration of the vibration motors, the spring can play a buffering role and also improve the vibration effect.

[0023] As Figures 2-3 As shown, the turning component includes four rotating shafts 2 rotatably connected to the inside of the processing box 1. On the outer side of the rotating shafts 2, there are fixed concave rollers 3. A crawler 5 is engaged between the four concave rollers 3. At the top of the processing box 1, there is installed a driving device 4 drivingly connected to the left end of the top rotating shaft 2. By driving the top rotating shaft to rotate through the driving device 4, the concave rollers follow, thereby being able to drive the crawler to rotate forward or backward, enabling the tires on the crawler to roll. At the same time, when adding steel balls, the steel balls will also roll accordingly, thereby being able to improve the effect of the steel balls adsorbing iron components.

[0024] There are a plurality of convex blocks 6 arranged at equal distances and tilted toward the lower right formed on the outer side of the crawler 5, a baffle 25 in contact with the upper surface of the convex block 6 is fixed on the front side wall of the processing box 1, and a screen plate 24 is fixed on the inner side of the processing box 1 below the crawler 5. When the steel ball is in the process of rolling and adsorption, the steel ball will also be located in the gap between the two convex blocks during the rolling process, and through the forward and reverse rotation of the crawler, the crawler drives the convex block to move to the baffle, the baffle can block the crushed tire, and can make the steel ball move below the baffle, so that the steel ball falls onto the screen plate, when the particles adsorbed by the steel ball are large, they will stay on the screen plate, and the rest will be discharged through the screen plate to the bottom of the processing box for collection.

[0025] like Figure 2 In the direction shown, the material return assembly includes a vertical box 19 located at the back of the processing box 1 and connected to the top of the heating box 26, a chain transmission device 20 is installed on the inner side of the vertical box 19, and a driving device 21 is installed on the top to be connected to the left end of the upper shaft end of the driving chain transmission device 20, and a screw 23 extending to the inside of the processing box 1 is fixed to the left end of the lower shaft end of the chain transmission device 20, and a plurality of hoppers 22 are fixed on the transmission chain of the chain transmission device 20, and a feed hopper is arranged on the back of the vertical box 19. When the steel balls are concentrated at the bottom of the processing box, the driving device 2 drives the chain transmission device to operate, so that the hopper can be driven to move by the chain, and the auger rotates accordingly, so that the steel balls can be transferred to the bottom of the vertical box, and then the steel balls are scooped up and moved to the top through the hopper to be introduced into the heating box, thereby completing the function of material return and realizing automatic circulation operation.

[0026] The working principle of the above embodiment is:

[0027] The crushed tires are introduced into the conveying cylinder on the left side. Then, the vibration motor operates to move the tires into the processing box and onto the track. Next, the driving device 1 drives the track to run, rotating clockwise and counterclockwise reciprocally. Meanwhile, the magnetizing box magnetizes the steel balls, and the switching valve opens to introduce the steel balls into the processing box to mix with the tires. When the track runs reciprocally, the tires and the steel balls can roll together, enabling the steel balls to fully adsorb the iron components. When the track rotates forward, some steel balls will be located between the two bumps. Due to the obstruction of the baffle, the steel balls can fall onto the sieve plate and then to the bottom of the processing box. By rotating counterclockwise, the tires can be exported to the right side and into the right conveying cylinder due to the cooperation of the guide blocks. Then, the driving device 2 drives the chain transmission device to operate, which can drive the auger to rotate, thereby transferring the steel balls to the bottom of the vertical box. At the same time, the hopper will also operate with the chain transmission device, so it can scoop up the steel balls at the bottom of the vertical box and transfer them to the upper part to be introduced into the heating box. The steel balls are demagnetized by heating in the heating box. Then, the steel balls and the iron components under the heating box are guided into the conduit under the action of the arc-shaped steel column. Through contact with the water in the water tank in the conduit, the cooling treatment of the steel balls is completed. Then, they are introduced into the magnetizing box again through the inlet pipe for magnetization treatment. At the same time, the iron components will also fall into the water tank through the material distribution box for storage.

[0028] In summary, it can achieve automatic feeding and improve the mixing effect of tires and steel balls by tumbling, thereby completing the adsorption of iron components. Moreover, it can recycle the steel balls and strip the iron components on the steel balls, so it can effectively improve the separation effect and efficiency.
