[0002] With the continuous development of the new energy industry, the requirements for materials are getting higher and higher, and the safety performance of materials is one of the main directions of improvement.

[0003] Metal foreign objects are the key to affecting the safety performance of materials. To improve the safety performance of materials, the control of magnetic metal foreign objects is becoming more and more strict. The existing outer rail conveyor line is in the form of rollers and drums, which only plays a conveying role. The crucibles loaded with materials are prone to introduce metal foreign objects during production, transportation and use. Especially the bottom of the crucible is a cleaning blind area, and magnetic substances cannot be effectively cleaned, and there is a high risk that magnetic metal foreign objects are introduced into the system, resulting in an increase in magnetic metal foreign objects in the product and affecting the safety performance of the materials.

[0004] Therefore, how to provide a device that can eliminate magnetic foreign objects on the outer rail line of the positive electrode material kiln furnace has become an urgent technical problem to be solved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a magnetic roller and an outer rail line of a kiln furnace that can eliminate magnetic foreign objects on the outer rail line of the positive electrode material kiln furnace.

[0006] The first aspect of the utility model provides a magnetic roller, including:

[0007] A main shaft rotatably arranged on the outer rail line;

[0008] A cylinder body installed on the main shaft and rotatable with the main shaft;

[0009] A non-magnetic bracket protruding from the outer periphery of the cylinder body, which can support the bottom surface of the crucible along with the rotation of the cylinder body, and form a metal impurity adsorption space between the non-magnetic bracket and the surface of the cylinder body;

[0010] A magnetic member detachably arranged in the metal impurity adsorption space or in the cylinder body.

[0011] Optionally, the magnetic member includes a cylindrical magnetic member coaxially arranged inside the cylinder body, and the cylindrical magnetic member is in transitional fit with the cylinder body.

[0012] Optionally, the magnetic roller further includes limiting members arranged at both ends of the cylinder body, and the limiting members axially limit the cylindrical magnetic member.

[0013] Optionally, the cylinder body includes an external thread section and an internal thread section connected by threads, and the limiting members include two fixed snap rings arranged at the free ends of the external thread section and the internal thread section, and the cylindrical magnetic member is arranged between the two fixed snap rings.

[0014] Optionally, the magnetic member includes magnetic sheets that can be adsorbed on the surface of the cylinder.

[0015] Optionally, the non-magnetic support includes two or more non-metallic rings that are spaced apart axially on the cylinder.

[0016] Optionally, the material of the non-metallic ring is selected from wear-resistant non-metallic ceramics.

[0017] Optionally, the non-magnetic support further includes a plurality of non-metallic ring bearings coaxially fixed outside the cylinder, and the non-metallic rings are respectively mounted on the non-metallic ring bearings.

[0018] In a second aspect of the present invention, there is provided an outer rail line of a kiln, including a feeding section, a conveying section, and a discharging section. The conveying rollers in the feeding section and / or the discharging section adopt the magnetic rollers according to any one of the first aspect of the present invention.

[0019] Optionally, there are 3 to 5 magnetic rollers provided in the feeding section and / or the discharging section.

[0020] Optionally, the non-magnetic supports of the magnetic rollers in the feeding section and / or the discharging section are flush with the conveying rollers of the conveying section in height.

[0021] Optionally, the height of the non-magnetic support in the magnetic roller is 1 - 2 mm.

[0022] According to the technical content disclosed in the present invention, the following beneficial effects are achieved:

[0023] The magnetic roller provided by the present invention includes a cylinder that can rotate around a main shaft, a magnetic member provided on the cylinder and detachably connected to the cylinder; and a non-magnetic support located on the outer periphery of the magnetic roller. When conveying the firing box, the non-magnetic support supports on the bottom surface of the box, forming a metal impurity adsorption space between the non-magnetic support and the surface of the cylinder; as the magnetic roller rotates, the firing box is conveyed forward, and the metal impurities at the bottom of the box are adsorbed onto the surface of the magnetic roller under the magnetic force of the magnetic member. Since there is a preset distance between the bottom surface of the firing box and the outer peripheral surface of the magnetic roller, the firing box will not touch the adsorbed metal impurities during the conveying process. When the adsorbed metal impurities accumulate to a certain thickness, the magnetic member inside the cylinder can be detached from the cylinder. The cylinder itself does not have magnetic force, and the magnetic impurities will fall off from the surface of the cylinder. When the magnetic member is provided on the outer periphery of the cylinder, the magnetic member can be detached, and after cleaning the metal impurities on the surface of the magnetic member, it can be reinstalled on the outer periphery of the cylinder. The repeated use of the magnetic roller is realized.

[0032] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that: like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] See Figure 1 and Figure 2 , the present utility model discloses a magnetic drum, which is installed on the outer track line of a kiln and is used to adsorb metal impurities at the bottom of a sagger on the outer track line. It includes: a main shaft 1, a cylinder body 2, a magnetic member, a non-metallic ring bearing 31, a non-magnetic bracket, and a limiting member. Among them, in this embodiment, the magnetic member is a cylindrical magnetic member 5, the non-magnetic bracket is a non-metallic ring 32, and the limiting member is a fixed snap ring 4.

[0035] The main shaft 1, the cylindrical magnetic part 5 and the cylinder body 2 are coaxially arranged in sequence along the radial direction of the magnetic drum and from the axis to the outer periphery. The cylinder body 2 is installed on the main shaft 1 and can rotate with the main shaft 1. The cylindrical magnetic part 5 is embedded inside the cylinder body 2 and is detachably connected to the cylinder body 2. The outer wall of the cylindrical magnetic part 5 abuts against the inner wall of the cylinder body 2, that is, the cylindrical magnetic part 5 and the cylinder body 2 are transitionally fitted and detachably arranged on the cylinder body 2. Specifically, the fixed snap ring 4 is embedded on the inner peripheral wall of the cylinder body 2, and a fixed snap ring 4 is arranged at each end of the cylindrical magnetic part 5, and the fixed snap ring 4 axially limits the cylindrical magnetic part 5. The two non-metal rings 32 are arranged at intervals in the axial direction of the cylinder body 2. More specifically, the cylinder body 2 includes a first part 21 and a second part 22 arranged in sequence. The first part 21 includes an external thread section at one end, and the second part 22 includes an internal thread section at one end. A fixed snap ring 4 is arranged inside the free ends of the first part 21 and the second part 22 respectively, and the external thread section is threadedly connected to the internal thread section.

[0036] The non-metal ring bearing 31 is nested on the outer periphery of the cylinder body 2, and the non-metal ring 32 made of wear-resistant non-metal ceramics is installed on the non-metal ring bearing 31. The non-metal ring 32 and the non-metal ring bearing 31 are both coaxial with the main shaft 1, and the non-metal ring 32 can rotate relative to the non-metal ring bearing 31. The non-metal ring 32 protrudes from the outer peripheral surface of the cylinder body 2 by a preset height. When conveying the firing box, the non-metal ring 32 supports on the bottom surface of the firing box, and a metal impurity adsorption space is formed between the bottom surface of the firing box and the surface of the cylinder body 2. It should be noted that multiple non-metal ring bearings 31 can be arranged at intervals, and multiple non-metal rings 32 are correspondingly installed on the non-metal ring bearings 31 one by one.

[0037] In this embodiment, a detachable cylindrical magnetic part 5 is added inside the magnetic drum of the outer rail conveying line to adsorb magnetic metal foreign objects at the bottom of the firing box, so as to achieve the purpose of demagnetization. The cylindrical magnetic part 5 is stably installed in transitional fit with the cylinder body 2 and will not generate shaking and collision. The cylinder body 2 includes a first part 21 and a second part 22 arranged in sequence and threadedly connected, which is convenient for taking out the cylindrical magnetic part 5 inside the cylinder body 2. The magnetic drum is designed with wear-resistant non-metal ceramic protrusions (the combination of the non-metal ring bearing 31 and the non-metal ring 32) of 1-2 mm to carry the firing box to run normally on the roller. During the conveying process of the firing box on the outer rail line, demagnetization is carried out on the bottom of the firing box. After running for one week, the detachable cylinder body 2 is disassembled to clean the magnetic foreign objects, and the cleaning frequency is determined to be reduced or increased according to the actual weight of the magnetic metal foreign objects. The non-metal ring bearing 31 can reduce the damping between the magnetic drum and the firing box.

[0038] In some other embodiments, the magnetic member includes a magnetic patch which can be freely bent and attached to the cylinder 2. After installation, the magnetic patch is pasted and wound around the outer peripheral wall of the cylinder 2. The non-metal ring bearing 31 is nested on the outer peripheral surface of the magnetic patch, and the non-metal ring 32 made of wear-resistant non-metal ceramics is installed on the non-metal ring bearing 31. The non-metal ring 32 protrudes from the outer surface of the magnetic patch by a preset height. When conveying the pot, the non-metal ring 32 supports on the bottom surface of the pot, and a metal impurity adsorption space is formed between the bottom surface of the pot and the outer surface of the magnetic patch, that is, the magnetic patch pasted and wound around the outer peripheral wall of the cylinder 2 is distributed in the metal impurity adsorption space. The magnetic patch is regularly disassembled and cleaned, and at the same time, the magnetic patch can be reused. By this method, the purpose of adsorbing magnetic metal foreign matters at the bottom of the pot is achieved. The non-metal ring bearing 31 can reduce the damping between the magnetic roller and the pot, preventing the magnetic patch from being damaged due to excessive damping.

[0039] The second aspect of the present invention provides an outer rail line of a kiln. The outer rail line includes a feeding section, a conveying section, and a discharging section. The conveying rollers in the feeding section and / or the discharging section adopt the magnetic roller according to any one of the first aspect of the present invention. There are 3 to 5 of the magnetic rollers provided in the feeding section and / or the discharging section. Specifically, after the pots are separated in the outer rail line and before entering the kiln, 5 magnetic rollers are replaced respectively. 1-2 mm wear-resistant non-metal ceramic protrusions (a combination of the non-metal ring bearing 31 and the non-metal ring 32) are designed on the magnetic rollers, which are flush with the conveying rollers in the conveying section. When the pot passes through, magnetic metal foreign matters at the bottom are adsorbed. After running for one week, the magnetic rods of the magnetic rollers are pulled out, the foreign matters inside the outer rail are cleaned and the weight is recorded. The weight trend of the metal foreign matters is confirmed and the composition of the foreign matters is analyzed. When the trend of the metal foreign matters is abnormal, the source of the introduced metal foreign matters is investigated and eliminated from the source. After the magnetic rollers are cleaned, they are reinstalled on the outer rail line and continue to run. The outer rail conveying line is increased with a magnetic adsorption function to adsorb and collect the magnetic metal foreign matters existing at the bottom of the pot during use, avoiding introduction into the system. At the same time, the magnetic rollers are added with a detachable function, which is convenient for collecting and cleaning the foreign matters, improving the efficiency and quality of production operations.

[0040] Working principle: The present invention adsorbs magnetic metal foreign matters at the bottom of the pot through the magnetic rollers on the outer rail line body during the transportation of the pot, thereby reducing the risk of introducing magnetic metal foreign matters into the system. At the same time, 1-2 mm wear-resistant non-metal ceramic protrusions are made at both ends of the roller to prevent secondary pollution to the pot during transportation. By designing the easily detachable cylinder 2, after the magnetic member is disassembled, the magnetic metal foreign matters can be directly and quickly cleaned, improving the cleaning efficiency and effect.
