Description

Technical Field

[0001] This utility model relates to a waste separation device, and more particularly to a waste magnetic separation device. Background Technology

[0002] Because multi-station cold heading machines drop metal scrap into the cold heading oil during production, manufacturers need to filter the cold heading oil after it is discharged. The filtered cold heading oil is then returned to the cold heading machine for reuse, while the filtered waste is collected and recycled. Currently, the existing method for filtering cold heading oil involves passing it through a filter cylinder with numerous perforations on its surface. This allows the cold heading oil to pass directly out of the filter cylinder after entering, while the metal scrap is trapped inside and periodically emptied by the manufacturer.

[0003] However, the drawback of this filtration method is that, since the amount of metal waste produced by the cold heading machine during the production process is relatively large, the metal waste can easily clog the external filter holes after accumulating, thereby reducing the filtration efficiency of the cold heading oil. On the other hand, the filter cartridge also needs to be frequently emptied of the metal waste during operation, which means that it is impossible to achieve long-term continuous filtration of the cold heading oil.

[0004] Therefore, a waste separation device capable of continuously filtering cold heading oil is needed. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic separation device for waste materials. It can achieve continuous filtration of cold heading oil and ensure the filtration efficiency of the cold heading oil.

[0006] The technical solution of this utility model is as follows: A waste magnetic attraction separation device includes an outer shell, one end of which is provided with a drain hole, and the other end of which is provided with a discharge port. A magnetic attraction channel is formed in the middle of the outer shell, and a hollow tube fixedly connected to the outer shell is provided in the magnetic attraction channel. A guide ring is spirally wound on the outer surface of the hollow tube, and one end of the guide ring extends to the middle of the discharge port. A magnetic attraction rod rotatably connected to the outer shell is provided on the inner side of the hollow tube. Several magnetic blocks are spirally distributed on the surface of the magnetic attraction rod, and one end of the magnetic attraction rod is connected to a driving mechanism.

[0007] In the aforementioned waste magnetic separation device, the spiral distribution direction of the magnetic blocks is opposite to the spiral direction of the guide ring, and the magnetic poles of adjacent magnetic blocks are arranged alternately in the spiral distribution direction.

[0008] In the aforementioned waste magnetic separation device, the two ends of the outer shell are fastened with intermediate sleeves, the intermediate sleeves and the outer shell are connected to each other by screws, the intermediate sleeves and the magnetic suction rod are connected to each other by bearings, and the end of the hollow tube is sleeved on the outside of the intermediate sleeve and connected to the intermediate sleeve by screws.

[0009] In the aforementioned waste magnetic separation device, the two ends of the outer shell are detachably connected to partitions, and the middle of the partitions is provided with a round hole for the intermediate sleeve to pass through. After the intermediate sleeve and the hollow tube are connected to each other, the partitions are squeezed and fixed from both sides.

[0010] In the aforementioned waste magnetic separation device, a discharge port is formed above the middle of the magnetic channel, and cover plates are placed on the outer shells on both sides of the discharge port.

[0011] In the aforementioned waste magnetic separation device, a baffle for intercepting waste is provided on the outer shell above the discharge port.

[0012] Compared with the prior art, this utility model has the following characteristics:

[0013] (1) Through the structural cooperation of hollow tube, magnetic rod and magnetic block, the present invention enables the metal waste in cold heading oil to be attracted to the outer surface of hollow tube after falling into the magnetic channel; through the structural cooperation of magnetic rod and guide ring, the magnetic rod can drive the attracted metal waste to rotate along the circumference of hollow tube after rotation, and the metal waste is intercepted and guided by the guide ring to roll towards the discharge port during rotation; while the cold heading oil flows along the inclined outer shell towards the drain hole and is discharged outward through the drain hole; under the above cooperation, the present invention can achieve the separation of metal waste and cold heading oil on the one hand, and the real-time discharge of metal waste on the other hand, which effectively avoids the continuous accumulation of metal waste in the magnetic channel and prevents blockage, thus ensuring the filtration efficiency of the present invention during long-term use;

[0014] (2) By limiting the connection structure of the outer shell, magnetic rod and hollow tube, the sealing of the hollow tube after installation is guaranteed, thereby preventing cold heading oil from seeping in from the installation gap of the hollow tube and affecting the rotational stability of the magnetic rod; on the other hand, it also enables the later installation and removal of each component, thus facilitating maintenance and replacement by operators.

[0015] (3) By combining the partition and the outer shell, the hollow tube, magnetic rod, intermediate sleeve and partition can be assembled on the outside of the outer shell first, and then the assembly is inserted into the magnetic channel and fixed by screws, which further facilitates the assembly of this utility model by the operator.

[0016] Therefore, this invention can achieve continuous filtration of cold heading oil and ensure the filtration efficiency of cold heading oil. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] Example 1. A waste magnetic separation device, configured as follows: Figure 1-3 As shown, the device includes an inclined outer shell 1, a drain hole 2 at the lower end of the inclined direction, a discharge port 3 at the upper end of the inclined direction, a magnetic suction channel 4 in the middle of the outer shell 1, a hollow tube 5 fixedly connected to the outer shell 1 inside the magnetic suction channel 4, a gap for the feeding liquid and metal waste to fall between the hollow tube 5 and the inner wall of the outer shell 1, a guide ring 6 spirally wound on the outer surface of the hollow tube 5, one end of the guide ring 6 extending to the middle of the discharge port 3, a magnetic suction rod 7 rotatably connected to the outer shell 1 on the inner side of the hollow tube 5, the magnetic suction rod 7 and the hollow tube 5 are coaxially arranged, a number of magnetic blocks 8 are spirally distributed on the surface of the magnetic suction rod 7, the magnetic blocks 8 and the magnetic suction rod 7 are glued together, and a drive mechanism 9 is connected to one end of the magnetic suction rod 7.

[0024] The spiral distribution direction of the magnetic block 8 is opposite to the spiral direction of the guide ring 6. The magnetic poles of adjacent magnetic blocks 8 are arranged alternately in the spiral distribution direction, and the adjacent magnetic blocks 8 are spaced apart.

[0025] The outer shell 1 is fastened to both ends with intermediate sleeves 10. The intermediate sleeves 10 and the outer shell 1 are connected to each other by screws. The intermediate sleeves 10 and the magnetic rod 7 are connected to each other by bearings. The end of the hollow tube 5 is sleeved on the outside of the intermediate sleeves 10 and connected to the intermediate sleeves 10 by screws.

[0026] A material discharge port is formed above the middle of the magnetic suction channel 4. Cover plates 12 are placed on the outer shell 1 on both sides of the material discharge port, and the cover plates 12 are fastened to the top of the outer shell 1.

[0027] The outer casing 1 above the discharge port 3 is provided with a baffle 13 for intercepting waste.

[0028] The working principle of this invention is as follows: During use, cold heading oil, along with scrap metal, falls from the discharge port into the magnetic channel 4. Upon entering, the scrap metal is attracted by the magnetic rod 7 and the magnetic block 8, causing it to adhere to the outer surface of the hollow tube 5 under magnetic attraction. The drive mechanism 9 continuously rotates the magnetic rod 7, and the magnetic block 8, in turn, causes the scrap metal to rotate circumferentially along the hollow tube 5.

[0029] When the scrap metal rotates to contact the guide ring 6, the guide ring 6 can intercept and guide the scrap metal, allowing it to move along the guide ring 6 towards the discharge port 3 during circumferential rotation.

[0030] When the metal scrap moves to the end of the guide ring 6, the partition 11 can circumferentially limit the metal scrap, so that the metal scrap is displaced and separated from the inner magnetic block 8 under the limiting action, that is, the adsorption of the metal scrap is released, and the metal scrap falls freely from the discharge port 3 after losing magnetic attraction, thereby realizing the separation and continuous discharge of the metal scrap relative to the cold heading oil.

[0031] After entering the magnetic channel 4, the cold heading oil flows along the bottom slope of the outer shell 1 toward the drain hole 2 and is discharged outward through the drain hole 2, thereby achieving the filtration and collection of the cold heading oil and facilitating the manufacturer's recycling of the cold heading oil.

[0032] Example 2. A waste magnetic separation device, configured as follows: Figure 4 As shown, the device includes an inclined outer shell 1, a drain hole 2 at the lower end of the inclined direction, a discharge port 3 at the upper end of the inclined direction, a magnetic suction channel 4 in the middle of the outer shell 1, a hollow tube 5 fixedly connected to the outer shell 1 inside the magnetic suction channel 4, a gap for the feeding liquid and metal waste to fall between the hollow tube 5 and the inner wall of the outer shell 1, a guide ring 6 spirally wound on the outer surface of the hollow tube 5, one end of the guide ring 6 extending to the middle of the discharge port 3, a magnetic suction rod 7 rotatably connected to the outer shell 1 on the inner side of the hollow tube 5, the magnetic suction rod 7 and the hollow tube 5 are coaxially arranged, a number of magnetic blocks 8 are spirally distributed on the surface of the magnetic suction rod 7, the magnetic blocks 8 and the magnetic suction rod 7 are glued together, and a drive mechanism 9 is connected to one end of the magnetic suction rod 7.

[0033] The drive mechanism 9 is a drive motor, which is connected to the magnetic rod 7 via a coupling. The drive motor can be connected to the end of the outer shell 1 by bracket screws, or it can be fixed to one side of the outer shell 1 by a mounting bracket.

[0034] The spiral distribution direction of the magnetic block 8 is opposite to the spiral direction of the guide ring 6. The magnetic poles of adjacent magnetic blocks 8 are arranged alternately in the spiral distribution direction, and the adjacent magnetic blocks 8 are spaced apart.

[0035] The outer shell 1 is fastened to both ends with intermediate sleeves 10. The intermediate sleeves 10 and the outer shell 1 are connected to each other by screws. The intermediate sleeves 10 and the magnetic rod 7 are connected to each other by bearings. The end of the hollow tube 5 is sleeved on the outside of the intermediate sleeves 10 and connected to the intermediate sleeves 10 by screws.

[0036] The outer shell 1 is detachably connected to two ends of a partition 11. The partition 11 has a round hole in the middle for the intermediate sleeve 10 to pass through. After the intermediate sleeve 10 and the hollow tube 5 are connected to each other, the partition 11 is squeezed and fixed from both sides.

[0037] A material discharge port is formed above the middle of the magnetic suction channel 4. Cover plates 12 are placed on the outer shell 1 on both sides of the material discharge port, and the cover plates 12 are fastened to the top of the outer shell 1.

[0038] The outer casing 1 above the discharge port 3 is provided with a baffle 13 for intercepting waste.

[0039] Compared with Embodiment 1, this embodiment detachably connects the partition 11 and the outer shell 1, allowing the hollow tube 5, magnetic rod 7, intermediate sleeve 10 and partition 11 to be connected to form an integrated structure during assembly. Then, the component is inserted into the magnetic channel 4 and screwed to the outer shell 1, thereby effectively improving the overall assembly efficiency of the device and facilitating the manufacturer's subsequent disassembly.
