Description

Technical Field

[0001] This utility model relates to the field of magnetic roller sleeve tooling technology, and in particular to a magnetic roller sleeve tooling for a magnetic separator. Background Technology

[0002] The magnetic roller sleeve fixture is an auxiliary device for the magnetic roller component in magnetic separation equipment. The magnetic roller is one of the core components of the magnetic separator, and the sleeve fixture is mainly fitted on the outer layer of the magnetic roller, serving multiple functions such as protection, performance optimization, and ease of assembly.

[0003] For example, CN202778708U discloses a magnetic roller for a magnetic separator used in mineral processing, which includes a magnetic shaft with magnetic blocks installed and a rotating sleeve. The magnetic field strength on the outer surface of the rotating sleeve gradually decreases from the front end to the rear end along the axial direction. An axial propulsion device from the front end to the rear end is provided on the outer surface of the rotating sleeve.

[0004] However, in the existing technology, heat is generated during the magnetic separation process, especially during long-term continuous operation. The temperature of the magnetic roller sleeve tooling will gradually increase. Excessive temperature will cause the performance of the tooling material to deteriorate, and problems such as reduced magnetic permeability of magnetic materials and deformation of tooling due to thermal expansion of materials will occur, which will directly affect the normal operation of the magnetic separator. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, the temperature of the magnetic roller sleeve tooling gradually increases during long-term continuous operation. Excessive temperature will lead to a decrease in the performance of the tooling material, and the magnetic permeability of the magnetic material will decrease, and the thermal expansion of the material will cause the tooling to deform. Therefore, a magnetic roller sleeve tooling for magnetic separators is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic roller sleeve tooling for a magnetic separator, comprising a sleeve body, both ends of which are fixedly mounted with closed panels, a central shaft is fixedly mounted at the center of the closed panels, a magnetic block is fixedly mounted on the outer wall of the inner part of the central shaft, and a heat dissipation component is fixedly mounted inside the sleeve body.

[0007] The heat dissipation assembly includes a hollow tube, a threaded rod, and a piston. The piston is threaded onto the outer wall of the threaded rod, and the threaded rod is rotatably installed inside the hollow tube. The hollow tube is fixedly installed between two closed panels along the axis of the sleeve body. The hollow tube is located between two adjacent magnetic blocks, and an exhaust end is fixedly connected to the junction of the hollow tube and the closed panel.

[0008] Preferably, a driven gear is fixedly installed at one end of the threaded rod, and a large gear ring is rotatably connected to the outer wall of the central shaft, with the large gear ring and the driven gear being rotatably connected.

[0009] Preferably, an extension rod is fixedly installed on one side of the large toothed ring.

[0010] Preferably, the hollow tube has columnar, equally spaced ventilation holes on its wall, and an annular plate is fixedly installed on the wall of each ventilation hole.

[0011] Preferably, a guide rod is fixedly connected inside the annular plate, and one end of the guide rod is connected to a sealing plate via a spring. The edge of the sealing plate is slidably connected to the wall of the vent hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a hollow tube is set inside the sleeve body, and a movable piston is set inside the hollow tube. During the movement of the piston, a negative pressure is generated, which draws the air inside the entire sleeve body into the hollow tube. Then, during the reverse movement, the air is discharged from the other end, and fresh air is injected into the sleeve body from the exhaust end of the other end, thereby completing an air exchange and reducing the temperature of the sleeve body. This ensures that the sleeve body can be used for a long time without affecting the magnetic permeability of the magnetic material. At the same time, the cooling treatment can also avoid the problem of tooling deformation.

[0014] 2. In this utility model, by setting a large gear ring on the central shaft, the driven gear is driven by pushing the large gear ring during use, thereby driving the threaded rod. By controlling the clockwise and counterclockwise rotation of the large gear ring, the direction of movement of the piston rod can be changed. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a magnetic roller sleeve tooling for a magnetic separator, including a sleeve body 1. Both ends of the sleeve body 1 are fixedly installed with closed panels 6. A central shaft 2 is fixedly installed at the center of the closed panel 6. A magnetic block 7 is fixedly installed on the outer wall of the inner part of the central shaft 2. A heat dissipation component 3 is fixedly installed inside the sleeve body 1.

[0024] The heat dissipation assembly 3 includes a hollow tube 31, a threaded rod 33, and a piston 34. The piston 34 is threaded onto the outer wall of the threaded rod 33. The threaded rod 33 is rotatably mounted inside the hollow tube 31. The hollow tube 31 is fixedly mounted between two closed panels 6 along the axis of the sleeve body 1. The hollow tube 31 is located between two adjacent magnetic blocks 7. A driven gear 35 is fixedly mounted at one end of the threaded rod 33. An exhaust end 32 is fixedly connected at the junction of the hollow tube 31 and the closed panel 6. A large gear ring 4 is rotatably connected to the outer wall of the central shaft 2. The large gear ring 4 is rotatably connected to the driven gear 35. An extension rod 5 is fixedly mounted on one side of the large gear ring 4.

[0025] The specific setup and function of this embodiment are described below. The central shaft 2 is arranged along the axis of the sleeve body 1. Both ends of the sleeve body 1 are provided with closed panels 6 connected to the central shaft 2. Magnetic blocks 7 are fixedly installed on the surface of the central shaft 2. In use, the central shaft 2 is fixedly connected to the output end of the magnetic separator. When a mixture containing magnetic and non-magnetic minerals passes through the magnetic roller of the magnetic separator, the magnetic minerals will be attracted by the magnetic field generated by the magnetic blocks 7 and adsorbed onto the surface of the sleeve body 1. As the sleeve body 1 rotates, the adsorbed magnetic minerals will be gradually brought to the concentrate collection area of ​​the magnetic separator, thereby achieving separation from the non-magnetic minerals.

[0026] During the rotation of the sleeve body 1, the friction between the sleeve body 1 and the material will generate a lot of heat. The rotation of the closed panel 6 will simultaneously drive the threaded rod 33 inside the hollow tube 31. The meshing transmission between the driven gear 35 at the end of the threaded rod 33 and the large gear ring 4 will drive the threaded rod 33. The threaded rod 33 pushes the piston 34 to move along the direction of the hollow tube 31, and discharges the air inside the hollow tube 31 from the exhaust end 32 to achieve the purpose of heat dissipation.

[0027] A pulley is fixedly installed at the end of the extension rod 5. During use, the pulley is connected to an external belt drive assembly, which includes a motor, a belt, and a pulley. This is existing technology and will not be described in detail here. After the piston 34 moves to the end of the hollow tube 31, the belt drive assembly drives the large gear ring 4 through the extension rod 5, causing the large gear ring 4 to rotate. The rotation direction of the large gear ring 4 is the same as the rotation direction of the sleeve body 1, but the rotation speed is faster. At this time, the large gear ring 4 will push the driven gear 35 in the opposite direction, causing the piston 34 to move to the other end of the hollow tube 31. The belt drive assembly stops operating after the piston 34 moves to the end of the hollow tube 31.

[0028] Example 2: Figure 2 and Figure 5 As shown, the hollow tube 31 has columnar vent holes 36 evenly spaced on its tube wall. An annular plate 37 is fixedly installed on the wall of the vent hole 36. A guide rod 39 is fixedly connected inside the annular plate 37. One end of the guide rod 39 is connected to a sealing plate 38 via a spring. The edge of the sealing plate 38 is slidably connected to the wall of the vent hole 36.

[0029] The overall effect of this embodiment is that the hollow tube 31 has an exhaust hole for air intake on its tube wall. During the movement of the piston 34, the sealing plate 38 is pushed against the wall of the vent hole 36 by the compressed air in its moving direction. A negative pressure is generated in the space behind the piston 34, which pulls the sealing plate 38 out of the vent hole 36. At the same time, external air is also drawn from the exhaust end 32 and injected into the sleeve body 1, thereby completing the air exchange and achieving the purpose of removing heat. The movement path of the sealing plate 38 is restricted by the guide rod 39, while the presence of the annular plate 37 is used to determine the position of the sealing plate 38.

[0030] The usage and working principle of this device are as follows: During the rotation of the sleeve body 1, the friction between the sleeve body 1 and the material will generate a lot of heat. During this process, the large gear ring 4 remains stationary. As the closed panel 6 rotates, the driven gear 35 will be pushed by the large gear ring 4, and drive the threaded rod 33 to rotate synchronously, so that the piston 34 moves along the direction of the hollow tube 31, and discharges the air in the hollow tube 31 from the exhaust end 32 to achieve the purpose of heat dissipation.

[0031] After the piston 34 moves to the end of the hollow tube 31, the belt drive assembly drives the large gear ring 4 to rotate faster in the direction of rotation with the sleeve body 1 via the extension rod 5. At this time, the large gear ring 4 will push the driven gear 35 in the opposite direction, causing the piston 34 to move to the other end of the hollow tube 31. The belt drive assembly stops operating after the piston 34 moves to the end of the hollow tube 31.

[0032] During the movement of piston 34, the sealing plate 38 in its direction of movement is pushed against the wall of vent 36 by compressed air, and a negative pressure is generated in the space behind piston 34, which pulls the sealing plate 38 out of vent 36. At the same time, external air is also drawn from exhaust end 32 and injected into sleeve body 1, thereby completing the air exchange and achieving the purpose of removing heat.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
