Description

Technical Field

[0001] This utility model relates to the technical field of devices used in the production of positive electrode materials, and more specifically, to a demagnetizing device for a sagger. Background Technology

[0002] In the production of cathode materials, the materials generally undergo a sintering process. Before entering the sintering process, the materials are placed in a special sagger. Due to the large amount of magnetic foreign matter adsorbed on the inner and outer surfaces of the sagger during initial use and repeated use, the current demagnetization method is to manually demagnetize the inner and outer surfaces of the sagger using a magnetic rod. This method has obvious disadvantages: 1. It involves a large workload and high labor intensity; 2. The standardization of the manual demagnetization process is low, and demagnetization may be irregular and incomplete; 3. Due to the large number of saggers and continuous output, manual demagnetization may miss some items.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a demagnetizing device for a sagger, which aims to improve at least one of the problems mentioned in the background art.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In the first aspect, this utility model provides a demagnetizing device for a sagger, which includes a magnetic suction component and a lifting mechanism;

[0007] The magnetic suction component has a downward-facing receiving cavity. The shape and size of the receiving cavity match the shape and size of the side wall of the sagger. The receiving cavity has an extension part. The receiving cavity is annular, and the extension part is located inside the annulus.

[0008] The lifting mechanism is located below the magnetic suction component. When not in operation, the lifting mechanism is located below the travel path of the sagger.

[0009] The lifting mechanism is configured such that when the sagger moves above the lifting mechanism, it pushes the sagger upward, causing the sagger to enter the receiving cavity, and at this time the extension part enters the sagger. After demagnetization, it drives the sagger to move down back to its original position.

[0010] In an optional embodiment, the lifting mechanism includes a power cylinder, a piston rod, and a support plate;

[0011] One end of the piston rod is located inside the power cylinder, and the other end is connected to the support plate;

[0012] The power cylinder is either a pneumatic cylinder or a hydraulic cylinder.

[0013] In an optional embodiment, a transfer device is included for transferring the sagger from one end to the other on the same horizontal plane. When not in operation, the transfer device is located between the magnetic suction element and the lifting mechanism.

[0014] The transmission device includes multiple rollers arranged on the same horizontal plane, each roller is connected to a rotation power device, and the lifting mechanism is located between two adjacent rollers.

[0015] In an optional embodiment, the sagger demagnetizing device further includes at least one magnetic rod;

[0016] Each magnetic rod is located between two adjacent rollers.

[0017] In an alternative implementation, at least one magnetic rod is positioned downstream of the crucible's movement path.

[0018] In optional implementations, sensors and timers are included;

[0019] The sensor is used to detect when the sagger moves to a preset position. The sensor is connected to the timer, and the timer is connected to the lifting mechanism.

[0020] The sensor is configured to sense the position signal of the sagger and send the position signal to the timer; the timer is configured to receive the position signal sent by the sensor and start timing after receiving the signal. When the timed time reaches the preset time, it sends a signal to the lifting mechanism, and the lifting mechanism starts to push the sagger up.

[0021] In an optional implementation, a sensor is included, which is positioned close to the lifting mechanism;

[0022] The sensor is configured to sense the position signal of the sagger and send the position signal to the lifting mechanism. After receiving the signal, the lifting mechanism begins to push the sagger upward.

[0023] The beneficial effects of the sagger demagnetizing device provided in this embodiment of the invention include:

[0024] During the movement of the sagger, when it passes under the magnetic suction device, the lifting mechanism is operated to push the sagger upwards, allowing it to enter the receiving cavity. The extension of the magnetic suction device then enters the sagger, attracting and removing ferromagnetic impurities from the sagger's walls, except for the bottom. Due to the special structure of the magnetic suction device, demagnetizing the sagger is convenient. Therefore, compared to manual demagnetization using a magnetic rod, this demagnetizing device is easier to use, more efficient, and more standardized, preventing any omissions during sagger movement.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] like Figure 1 As shown, this utility model embodiment provides a sagger demagnetizing device 100, which includes a magnetic suction element 110 and a lifting mechanism 120;

[0038] The magnetic suction member 110 has a downward-facing receiving cavity 111. The shape and size of the receiving cavity 111 match the shape and size of the side wall of the crucible 200. The receiving cavity 111 has an extension portion 112. Figure 1 The portion marked by the dotted circle in the middle), the receiving cavity 111 is annular, and the extension portion 112 is located inside the ring;

[0039] The lifting mechanism 120 is located below the magnetic suction component 110. When not in operation, the lifting mechanism 120 is located below the travel path of the sagger 200.

[0040] The lifting mechanism 120 is configured to push the sagger 200 upward when the sagger 200 moves above the lifting mechanism 120, so that the sagger 200 enters the receiving cavity 111, and at this time the extension part 112 enters the sagger 200. After demagnetization, the sagger 200 is driven to move down back to its original position.

[0041] During movement, when the crucible 200 passes under the magnetic suction member 110, the lifting mechanism 120 is operated to push the crucible 200 upward, allowing it to enter the receiving cavity 111. The extension portion 112 of the magnetic suction member 110 then enters the crucible 200, at which point the magnetic suction member 110 attracts and removes ferromagnetic impurities from the walls of the crucible 200, except for the bottom wall. Due to the special structure of the magnetic suction member 110, demagnetizing the crucible 200 is convenient. Therefore, compared to manual demagnetization using a magnetic rod 140, the demagnetizing device of this invention is more convenient and efficient.

[0042] Specifically, the magnetic component 110 can be made of a material that is inherently magnetic, such as neodymium iron boron or ferrite. Alternatively, the magnetic component 110 can be an electromagnet, which generates magnetism when energized.

[0043] Optionally, the lifting mechanism 120 includes a power cylinder 121, a piston rod 122, and a support plate 123; one end of the piston rod 122 is located inside the power cylinder 121, and the other end is connected to the support plate 123; the power cylinder 121 is a pneumatic cylinder or a hydraulic cylinder.

[0044] When the sagger 200 moves to directly above the support plate 123 in the direction of travel, gas or liquid is filled into the power cylinder 121, the piston cylinder rises, and the support plate 123 carries the sagger 200 upward into the receiving cavity 111.

[0045] Optionally, the sagger demagnetizing device 100 also includes a transmission device for transferring the sagger 200 from one end to the other on the same horizontal plane. When not in operation, the transmission device is located between the magnetic suction member 110 and the lifting mechanism 120.

[0046] The transmission device includes multiple rollers 130 arranged on the same horizontal plane, each roller 130 is connected to a rotation power device 170, and the lifting mechanism 120 is located between two adjacent rollers 130.

[0047] Each roller 130 rotates in the same direction, so that after the sagger 200 is placed on the roller 130, it can move along the distribution direction of the multiple rollers 130.

[0048] Optionally, the rotation power device 170 can be an electric motor; each roller 130 can be connected to one electric motor.

[0049] Or, such as Figure 2 As shown, the rotational power device 170 may further include a motor 171, a rotating shaft 172, multiple first bevel gears 173, and multiple second bevel gears 174. The output shaft of the motor 171 is connected to the rotating shaft 172, and the multiple first bevel gears 173 are evenly distributed along the length of the rotating shaft 172. The number of first bevel gears 173, second bevel gears 174, and rollers 130 is the same. One end of each roller 130 is connected to a second bevel gear 174, and each second bevel gear 174 meshes with a first bevel gear 173. The rotation of the motor 171 drives the rotating shaft 172 to rotate, thereby causing the first bevel gears 173 to rotate, which in turn drives the second bevel gears 174 to rotate, ultimately causing the rollers 130 to rotate.

[0050] Furthermore, the sagger demagnetizing device 100 also includes at least one magnetic rod 140; each magnetic rod 140 is located between two adjacent rollers 130.

[0051] A magnetic rod 140 is provided between two rollers 130 so that ferromagnetic impurities at the bottom of the crucible 200 are attracted by the magnetic rod 140 when it passes through this area. To improve the removal effect of impurities at the bottom, two or more magnetic rods 140 can be provided.

[0052] Optionally, at least one magnetic rod 140 is positioned downstream of the crucible 200's movement path. Positioning it downstream, compared to positioning it upstream, can thoroughly remove ferromagnetic impurities that have moved from the sidewall to the bottom wall during the crucible 200's movement.

[0053] Optionally, the lifting mechanism 120 can be configured to operate automatically. Specific implementation methods include the following two:

[0054] (1) such as Figure 3 As shown, the sagger demagnetizing device 100 also includes a sensor 150 and a timer 160; the sensor 150 is used to sense that the sagger 200 has moved to a preset position, the sensor 150 is communicatively connected to the timer 160, and the timer 160 is communicatively connected to the lifting mechanism 120.

[0055] Sensor 150 is configured to sense the position signal of sacrificial vessel 200 and send the position signal to timer 160; timer 160 is configured to receive the position signal sent by sensor 150 and start timing after receiving the signal. When the time reaches the preset time, it sends a signal to lifting mechanism 120, and lifting mechanism 120 starts to push sacrificial vessel 200 up.

[0056] The preset position is the position where the sensor 150 first senses the location of the crucible 200. The distance between this position and the lifting mechanism 120 is fixed. The time t for the crucible 200 to reach the lifting mechanism 120 from the preset position can be determined by the moving speed of the crucible 200. After the sensor 150 senses the crucible 200, the timer 160 starts timing. After time t, the crucible 200 moves exactly above the lifting mechanism 120. The lifting mechanism 120 immediately starts to push the crucible 200 up. After a certain time (e.g., 3~6s, the specific time can be set according to the demagnetization effect and the conveying speed of the crucible on the roller), the lifting mechanism descends and takes the crucible 200 back to the roller 130.

[0057] (2) such as Figure 4 As shown, the sagger demagnetizing device 100 includes a sensor 150, but may not include a timer 160. The sensor 150 is located near the lifting mechanism 120.

[0058] Sensor 150 is configured to sense the position signal of sapper 200 and send the position signal to lifting mechanism 120. After receiving the signal, lifting mechanism 120 begins to push sapper 200 up.

[0059] In this way, when sensor 150 senses sacrificial vessel 200, sacrificial vessel 200 is already above lifting mechanism 120, and then immediately controls lifting mechanism 120 to rise.

[0060] The specific configuration of the sensor 150 and the lifting mechanism 120 enables the automated operation of the entire sagger demagnetizing device 100.

[0061] In summary, the automatic demagnetizing device for saggers provided by this utility model has the following advantages:

[0062] 1. Easy to use and more efficient;

[0063] 2. More standardized, more thorough demagnetization;

[0064] 3. Demagnetizing during the movement of the sagger can prevent omissions.

[0065] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
