[0019] Compared with the prior art, the embodiment of the present utility model has the following advantages and beneficial effects:

[0020] 1. A water washing kettle for removing magnetic substances provided by the embodiment of the present utility model has a slot opened on the water washing kettle body, and a pulling mechanism is arranged on the outer wall of the water washing kettle body. The pulling mechanism has the functions of stretching and contracting. The pulling mechanism is used to drive the sealing plate to move to open and close the slot. A sealing plate is arranged on the pulling mechanism. When the pulling mechanism contracts or stretches, the sealing plate can just seal the slot. Since a magnet is arranged on the sealing plate, when the sealing plate seals the slot, the magnet will seal in the water washing kettle. In this way, the materials in the water washing kettle will contact or be adsorbed by the magnet, and the substances adsorbed by the magnet are magnetic substances, so as to realize the removal of magnetic substances in the materials. When the water washing process is over, the pulling mechanism can be controlled to contract or stretch, which will drive the sealing plate away from the slot, and the magnet will be exposed, facilitating the cleaning of the magnet. After removing the adsorbed substances, the magnet can be reused. The structure of the present utility model is simple and convenient to operate. Importantly, the efficiency of removing magnetic substances in the water washing kettle is high.

[0021] 2. In the embodiment of the present utility model, a clamping cup is arranged on the sealing plate for connecting the magnet. This connection method is a movable connection, which can not only improve the limiting stability of the magnet on the sealing plate, but also ensure the disassembly flexibility of the magnet. The clamping ring can further limit the magnet. The clamping cup is arranged at the lower end of the clamping ring, so that the bottom of the clamping cup can vertically support the magnet, further improving the limiting stability and preventing the magnet from being displaced during the water washing process, increasing the difficulty of cleaning the magnet.

[0022] 3. The pulling mechanism is set to include a first cylinder device and a second cylinder device. The telescoping of the pulling mechanism can be controlled by the air extraction device, and the operation is simple. The settings of the first limiting part and the second limiting part can improve the supporting stability of the sealing plate, ensuring that the notch can be accurately sealed when the first telescoping part and the second telescoping part contract.

[0023] Generally speaking, a water washing kettle for removing magnetic substances provided by the embodiment of the present utility model opens a slot on the body, sets a sealing plate, sets a magnet on the sealing plate, and realizes sealing the magnet in the chamber of the water washing kettle through the pulling mechanism, so as to achieve the purpose of improving the removal effect of magnetic substances in the lithium nickel cobalt manganese oxide cathode material.

[0033] In the description of the present utility model, it should be noted that the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance. Embodiment

[0034] Such as Figure 1As shown in the figure, the present utility model provides a water-washing kettle for removing magnetic substances, which includes a water-washing kettle body for accommodating materials and solutions to be cleaned. A slot 1 is provided on the water-washing kettle body. A pulling mechanism is arranged on the outer wall of the water-washing kettle body. A sealing plate 2 is arranged on the pulling mechanism, and a magnet 3 is arranged on the sealing plate 2. The pulling mechanism is used to drive the sealing plate 2 to move to open and close the slot 1. Exemplarily, the pulling mechanism is arranged to seal the slot 1 by the contraction of the sealing plate 2, or to open the slot 1 by the stretching of the sealing plate 2. When the sealing plate 2 seals the slot 1, the magnet 3 is located in the chamber of the water-washing kettle body. Specifically, the slot 1 provided on the water-washing kettle body is used for installing the sealing plate 2. The sealing plate 2 and the slot 1 are in an activity connection relationship, which can seal the slot 1 or open the slot 1. The specific opening and closing are controlled by the pulling mechanism. The pulling mechanism can control the sealing plate 2 to cover the slot 1 or control the sealing plate 2 to be away from the slot 1, having a certain telescopic function. In the embodiment of the present utility model, the magnet 3 is arranged on the sealing plate 2. When the pulling mechanism is compressed, the sealing plate 2 seals on the slot 1. The magnet 3 is arranged on the side of the sealing plate 2 facing the water-washing kettle body and will be sealed in the chamber of the water-washing kettle body. During the water-washing process of the materials in the chamber of the water-washing kettle body, the magnet 3 will adsorb the magnetic substances, so that the magnetic substances in the materials can be effectively removed. After the materials in the chamber of the water-washing kettle body are washed, the magnet 3 can be taken out for cleaning. At this time, the pulling mechanism stretches, or drives the sealing plate 2 to disengage from the slot 1 and has a certain distance from the water-washing kettle body. In this way, the magnet 3 will also disengage from the chamber of the water-washing kettle body and be exposed outside. The operator can clean the magnet 3 and the sealing plate 2, and even the magnet 3 can be taken out and cleaned separately. After cleaning, it is installed on the sealing plate 2 again. It should be noted that the sealing plate 2 can be made of materials such as metal, which is not limited here. The connection between the magnet 3 and the sealing plate 2 can be connected by welding, bonding, clamping and other methods, which is not limited here either. As a preferred embodiment of the present utility model, the connection between the magnet 3 and the sealing plate 2 is a detachable connection, which is beneficial to the cleaning and replacement of the magnet 3. Similarly, the shape of the magnet 3 is not limited here.

[0035] Exemplarily, such as Figure 2As shown, the magnet 3 has a rod-shaped structure. A cup 4 is provided on the sealing plate 2. One end of the magnet 3 is located inside the cup 4. The cup 4 on the sealing plate 2 is used to fix one end of the magnet 3. The cup 4 has a structure with one end open and one end closed, and can fix the magnet 3 both in the radial direction and the axial direction of the magnet 3, preventing the magnet 3 from moving or falling off during operation. At the same time, it is easy to disassemble and clean between the magnet 3 and the cup 4. It should be noted that the slot 1 can be provided on the top, bottom or side wall of the water washing kettle, and there is no limitation here. For the convenience of understanding, the slot 1 in the embodiment of the present invention is provided on the side wall of the water washing kettle body. Returning to the embodiment of the present invention, further, a snap ring 5 is also provided on the sealing plate 2, and the magnet 3 passes through the snap ring 5. The setting of the snap ring 5 can increase the fixing points of the magnet 3 on the sealing plate 2, can provide additional stability, and further improve the connection stability between the magnet 3 and the sealing plate 2. It should be noted that the number of the snap rings 5 provided here is not limited, and one or more snap rings 5 can be provided. Generally speaking, the more the number of the snap rings 5, the stronger the connection stability between the magnet 3 and the sealing plate 2. The cup 4 can also be provided at both ends of the magnet 3 respectively, not limited to one end of the magnet 3. Preferably, in the embodiment of the present invention, the cup 4 is only provided at one end of the magnet 3, and only one snap ring 5 is provided, and the snap ring 5 is provided at the upper end of the cup 4. In this way, the sealed end of the cup 4 will support the magnet 3 vertically, and can further improve the movable installation stability between the magnet 3 and the sealing plate 2. Of course, a limit protrusion 6 can also be provided at the other end of the magnet 3. The outer diameter of the limit protrusion 6 is larger than the inner diameter of the snap ring 5. In this way, the magnet 3 can only partially pass through the snap ring 5, and the limit protrusion 6 will prevent the magnet 3 from further moving, ensuring that the magnet 3 can be fixed more precisely at the required position.

[0036] As Figure 3As shown in the figure, the drawing mechanism of the present embodiment of the new model includes a first cylinder device and a second cylinder device, which are respectively arranged on opposite sides of the slot 1. Both the first cylinder device and the second cylinder device control the position of the sealing plate 2 by contraction and stretching. When the two cylinder devices contract simultaneously, they will act together on the sealing plate 2 to move the sealing plate 2 to cover the slot 1. One end of the magnet 3 is fixed by the cup 4, and the other end is fixed by the snap ring 5 and the limit protrusion 6, so as to enter the sealing chamber. When the two cylinder devices stretch simultaneously, the sealing plate 2 opens. It should be noted that the structures of the two cylinder devices can be realized by using the structures of the prior art. Specifically, a cylinder device is a device that converts the pressure energy of compressed air into mechanical energy. When the control valve is opened, compressed air is introduced into one side of the cylinder. The compressed air acts on one side of the piston, generating pressure and pushing the piston and the piston rod to move to the other side, resulting in the piston rod extending out of the cylinder body. This is the "extension" action of the cylinder. When the control valve opens the exhaust port on the other side or the port connected to the atmosphere, the pressure on one side of the piston decreases, and the piston is pulled back under the action of the spring force or external load, and the piston rod retracts into the cylinder body. This is the "contraction" action of the cylinder. The two cylinder devices can receive the supply of compressed air simultaneously to achieve two-way movement.

[0037] Specifically, the first cylinder device includes a first telescopic part 7 and a first limiting part 8, and the second cylinder device includes a second telescopic part 9 and a second limiting part 10. The first telescopic part 7 and the second telescopic part 9 are parallel to each other and are both perpendicular to the outer wall of the water washing kettle body; the first limiting part 8 is arranged at the end of the first telescopic part 7 away from the water washing kettle body, and the second limiting part 10 is arranged at the end of the second telescopic part 9 away from the water washing kettle body. The first limiting part 8 and the second limiting part 10 are arranged facing each other and are both parallel to the outer wall of the water washing kettle body; one end of the sealing plate 2 is connected to the first limiting part 8 and the other end is connected to the second limiting part 10; the first telescopic part 7 and the second telescopic part 9 are arranged to be able to extend or contract. The first telescopic part 7 and the second telescopic part 9 are the components in the cylinder device responsible for generating linear motion. They are parallel to each other and perpendicular to the outer wall of the water washing kettle body, that is, the telescopic action is also perpendicular to the outer wall of the water washing kettle. The first limiting part 8 and the second limiting part 10 are used to install the sealing plate 2 to ensure the stable installation of the sealing plate 2 and the precise limit of the installation angle. Through the above structure, the sealing plate 2 and the slot 1 can always be kept parallel. When the telescopic parts of the first cylinder device and the second cylinder device extend simultaneously, the sealing plate 2 is stretched, thereby opening the slot 1 on the water washing kettle body. When the telescopic parts of the two cylinder devices contract simultaneously, the sealing plate 2 is compressed, thereby closing the slot 1. Since the telescopic parts of the two cylinder devices are parallel, they can provide stable and uniform force to control the movement of the sealing plate 2, avoiding poor sealing or equipment damage caused by uneven force.

[0038] As a preferred embodiment of the present utility model, a first engaging mechanism 11 is provided on the slot 1, which can be a groove, a protrusion 6 or a mechanical structure of other shapes. A second engaging mechanism 12 is provided on the sealing plate 2, which can be a clamping groove, a clamping tongue or a mechanical structure of other shapes. The first engaging mechanism 11 and the second engaging mechanism 12 can be engaged with each other to achieve sealing, so as to achieve locking when the sealing plate 2 covers the slot 1. When the sealing plate 2 is pulled to the closed position by the first telescopic part 7 and the second telescopic part 9, the second engaging mechanism 12 is engaged with the first engaging mechanism 11. After the engagement, a sealed connection is provided to prevent materials or liquids from leaking from the slot 1. Preferably, a sealing ring is sleeved on the first engaging mechanism 11 or the second engaging mechanism 12. The sealing ring can be made of an elastic material, such as rubber, silica gel or other synthetic materials, to adapt to different working environments and media. The sealing ring provides an additional sealing layer, which can effectively prevent liquids or gases from leaking through the gaps of the engaging mechanism. The cup 4 and the ring 5 can be sprayed with wear-resistant coatings such as ECTFE, PTFE, tungsten carbide, etc. to prevent the introduction of ferromagnetic substances during the process. The cup 4 and the ring 5 can be welded to the sealing plate 2. The connection between the sealing plate 2 and the first limiting part 8 and the second limiting part 10 can be connected by means of bonding, clamping, screw connection, etc., as long as the purpose of sufficient connection stability can be achieved. Of course, a single washing kettle can be provided with multiple slots 1, that is, multiple pulling mechanisms and magnets 3 are provided for common adsorption to improve the removal efficiency of ferromagnetic substances.

[0039] The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale. At the same time, the present utility model omits the description of well-known components, processing technologies and processes to avoid unnecessarily limiting the present utility model.
