[0023] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example:

[0025] Reference Figure 1 , Figure 2 and Figure 3 The present invention discloses a neodymium iron boron waste cleaning and screening device, comprising: a shell 1, wherein a conveyor belt 2 is provided inside the shell 1, and both sides of the conveyor belt 2 are in contact with the inner wall of the shell 1; a driving component 3 is provided at one end of the conveyor belt 2 for driving the conveyor belt 2 to rotate; a water storage tank 4 is fixedly installed on both sides of the shell 1, and a heating plate 5 is fixedly installed on the inner bottom wall of the water storage tank 4; and an exhaust mechanism 6 is provided in the middle of the top side of the shell 1 for extracting steam in the water storage tank 4 and guiding the steam to the neodymium iron boron waste.

[0026] The connecting mechanism 7 is located on both sides of the outer shell 1 and is used for communication between the inside of the outer shell 1 and the inside of the water storage tank 4.

[0027] Vibrating element 8, which is located at the top inside the conveyor belt 2, is used to drive the neodymium iron boron waste on the conveyor belt 2 to vibrate;

[0028] Magnetic plate 9 is located at the other end of the conveyor belt 2 and is fixedly connected to the inner wall of the outer shell 1. The outer wall of magnetic plate 9 is in contact with the inner wall of the conveyor belt 2. Magnetic plate 10 is fixedly connected to the bottom end of magnetic plate 9. Magnetic plate 10 is inclined and fixedly connected to the inner wall of the outer shell 1.

[0029] In this embodiment, when the improved NdFeB waste cleaning and screening device is used, the NdFeB waste is cleaned by blowing steam through it. This can effectively sterilize and disinfect, remove oil and odors, eliminate the need for frequent water changes in the equipment, and eliminate the need for cleaning fluid, thus reducing the cost of cleaning NdFeB waste.

[0030] Specifically: When using this improved NdFeB waste washing and screening device, please refer to... Figure 1 , Figure 2 and Figure 3 As shown, the drive unit 3 drives the conveyor belt 2 to rotate at a constant speed inside the outer shell 1. Then, through the existing NdFeB waste conveying equipment, the NdFeB waste is conveyed and spread flat on the conveyor belt 2 at the feeding end of the outer shell 1. As the conveyor belt 2 rotates, the NdFeB waste is gradually transported to the bottom of the exhaust mechanism 6. The exhaust mechanism 6 continuously extracts water vapor from the water storage tank 4 and causes the steam to flow downward at high speed and blow onto the NdFeB waste to complete the cleaning of the NdFeB waste. Subsequently, the water vapor, carrying condensed water and dirt attached to the NdFeB waste, flows back into the water storage tank 4 through the connecting mechanism 7 for reuse. The dirt is trapped in the water storage tank 4 by the adhesion of the water in the water storage tank 4.

[0031] It should be noted that when the drive unit 3 is started, the heating plate 5 is also started simultaneously to continuously heat the water in the water storage tank 4 to continuously generate water vapor. (A float valve is fixedly installed on the outer wall of the water storage tank 4, and the float valve is connected to the external water source through a pipe so that when the water level in the water storage tank 4 drops to the threshold, water is promptly added to the water storage tank 4 to keep the water level in the water storage tank 4 within the corresponding range. A valve is provided below the float valve for discharging water from the water storage tank 4.)

[0032] It should be noted that when the steam is used to clean the NdFeB waste, the vibrating element 8 continuously drives the NdFeB waste to vibrate. The blowing position of the steam on the NdFeB waste can be adjusted by the vibration of the NdFeB waste, thereby enhancing the cleaning effect of the steam on the NdFeB waste.

[0033] (Please refer to) Figure 1As shown, several belt conveyors are installed on the bottom side of the outer shell 1 for transporting the screened NdFeB waste and other waste materials. After the NdFeB waste is cleaned, the NdFeB waste can be constrained on the conveyor belt 2 by the attraction between the magnetic plate 10 and the NdFeB waste, while the other waste materials slide off the conveyor belt 2. Subsequently, as the distance between the magnetic plate 10 and the conveyor belt 2 gradually increases, the upward attraction on the NdFeB waste is gradually reduced. The NdFeB waste of different sizes can be screened by its own gravity. The screening of NdFeB waste can be completed during the cleaning process, which improves the recycling efficiency of NdFeB waste.

[0034] Specifically, after the NdFeB waste is cleaned, as the conveyor belt 2 rotates, the NdFeB waste is moved to the outer periphery of the magnetic plate 9. At this time, due to the adsorption force between the magnetic plate 9 and the NdFeB waste, the NdFeB waste is constrained on the conveyor belt 2 and moves with the conveyor belt 2. The remaining waste slides off the conveyor belt 2. When the NdFeB waste moves to below the magnetic plate 10, due to the gradual expansion of the magnetic plate 10 and the inner wall of the conveyor belt 2, the NdFeB waste of different sizes falls to different positions below the conveyor belt 2 due to the weight of the NdFeB waste of different sizes and the adsorption force between the NdFeB waste of different sizes and the magnetic plate 10. The remaining waste and the NdFeB waste of different sizes fall into different belt conveyors and are transported to different positions by different belt conveyors.

[0035] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the driving component 3 includes a driver 31, which is fixedly mounted on the outer wall of the housing 1. The other end of the conveyor belt 2 is provided with a driving rod 32, and both ends of the driving rod 32 are rotatably connected to the housing 1. The driving end of the driver 31 is fixedly connected to the driving rod 32, and the outer wall of the driving rod 32 is in contact with the inner wall of the conveyor belt 2.

[0036] In this embodiment, please refer to Figure 1 and Figure 2 As shown, when the device is in use, the driver 31 starts and drives the drive rod 32 to rotate (the driver 31 is mainly composed of a housing, a servo motor and a gear transmission structure). Due to the friction between the drive rod 32 and the conveyor belt 2 and the tension of the drive rod 32 and the magnetic plate 9 on the conveyor belt 2, the rotating driver 31 drives the conveyor belt 2 to move along a fixed trajectory.

[0037] In a further preferred embodiment of this utility model, such as Figure 2 As shown, soft sleeves 11 are provided on both sides of the exhaust mechanism 6, and the soft sleeves 11 are rotatably connected to the outer shell 1 through a rotating shaft. The outer wall of the soft sleeves 11 is in contact with the top side of the conveyor belt 2 and the inner wall of the outer shell 1.

[0038] In this embodiment, please refer to Figure 2 As shown, during the movement of the conveyor belt 2, due to the friction between the soft sleeve 11 and the conveyor belt 2, the conveyor belt 2 drives the soft sleeve 11 to rotate. Due to the push of the gas inside the soft sleeve 11, the soft sleeve 11 always fits against the inner wall of the outer shell 1 and the conveyor belt 2, so that the water vapor discharged by the exhaust mechanism 6 will hardly overflow from the top opening of the outer shell 1. Furthermore, through the expansion and contraction deformation of the soft sleeve 11, the setting of the soft sleeve 11 will not affect the conveyor belt 2 from moving the neodymium iron boron waste below the exhaust mechanism 6.

[0039] It should be noted that the exhaust mechanism 6 mainly consists of an air pump, a connecting pipe splitter shell, and several nozzles.

[0040] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the vibrating element 8 includes a support plate 81, which is disposed on the inner top wall of the conveyor belt 2, and both sides of the support plate 81 are fixedly connected to the inner wall of the outer shell 1 through elastic strips. Several vibrators 82 are fixedly installed on the bottom side of the support plate 81.

[0041] In this embodiment, please refer to Figure 2 As shown, the support plate 81 can effectively support the middle part of the top side of the conveyor belt 2, and the elastic strip can effectively isolate the vibration transmission between the support plate 81 and the outer shell 1 (the elastic strip can be made of elastic materials such as hard rubber or elastic plastic).

[0042] When steam cleans the NdFeB waste, the vibrator 82 continuously drives the support plate 81 to vibrate (the vibrator 82 is mainly composed of a protective shell and a vibration motor, and the conveyor belt 2 is made of metal materials such as spring steel or elastic alloy). The vibration is then transmitted to the NdFeB waste through the conveyor belt 2, driving the NdFeB waste to vibrate, thereby changing the blowing position of the steam on the NdFeB waste.

[0043] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a magnetic shielding plate 12 is provided between the support plate 81 and the magnetic plate 10, and both sides of the magnetic shielding plate 12 are fixedly connected to the inner wall of the outer shell 1. The two ends of the magnetic shielding plate 12 are in contact with the inner wall of the magnetic plate 9 and the outer wall of the drive rod 32, respectively.

[0044] In this embodiment, please refer to Figure 2 As shown, the magnetic shielding plate 12 can effectively isolate the attraction force exerted by the magnetic plate 9 and the magnetic plate 10 on the NdFeB waste material above the support plate 81, and prevent the NdFeB waste material above the support plate 81 from being affected by the attraction force of the magnetic plate 9 and the magnetic plate 10, thus avoiding affecting the vibration of the NdFeB waste material.

[0045] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting mechanism 7 includes two heat-conducting plates 71, which are hollow inside and fixedly installed on the top side of the two heating plates 5 respectively. The heat-conducting plates 71 are fixedly connected to the inner wall of the corresponding water storage tank 4. The interior of the heat-conducting plates 71 is connected to the interior of the outer shell 1 through the guide plate 72. The inner bottom wall of the top opening of the guide plate 72 is coplanar with the top side of the conveyor belt 2. Several pressure-limiting valves 73 are fixedly installed on the top side of the heat-conducting plates 71 through round holes.

[0046] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the steam finishes cleaning the NdFeB waste, part of the steam condenses into water on the NdFeB waste and slides down onto the conveyor belt 2, while the other part of the steam, carrying the condensed water and the dirt that has settled on the NdFeB waste, flows along the top outer wall of the conveyor belt 2 into the guide plate 72, and then passes through the pressure relief valve 73 into the water in the water storage tank 4. Due to the adsorption force of the water in the water storage tank 4, the dirt is trapped and stored in the water storage tank 4, while the water and steam are dissolved in the water or steam in the water storage tank 4 for reuse.

[0047] It should be noted that there is only a small gap between the bottom of the pressure relief valve 73 and the inner wall of the heat conduction plate 71, which facilitates the direct pressure of water and dirt in the heat conduction plate 71 into the pressure relief valve 73 by the flowing steam, and then into the water in the water storage tank 4 along with the steam.

[0048] Please refer to Figure 3 As shown, when the heating plate 5 is running, the water in the water storage tank 4 continuously exchanges heat with the heating plate 5 through the heat conduction plate 71, thereby causing some of the water in the water storage tank 4 to continuously vaporize into water vapor.

[0049] Working principle: When this improved NdFeB waste cleaning and screening device is used, the NdFeB waste is conveyed and spread flat on the conveyor belt 2 at the feed end of the outer shell 1 through the existing NdFeB waste conveying equipment. The rotating conveyor belt 2 transports the NdFeB waste to the bottom of the exhaust mechanism 6. The exhaust mechanism 6 continuously extracts water vapor from the water storage tank 4 and causes the steam to flow downward at high speed and blow onto the NdFeB waste to complete the cleaning of the NdFeB waste.

[0050] After the NdFeB waste is cleaned, as the conveyor belt 2 rotates, the NdFeB waste is moved to the outer periphery of the magnetic plate 9. At this time, due to the adsorption force between the magnetic plate 9 and the NdFeB waste, the NdFeB waste is constrained on the conveyor belt 2 and moves with the conveyor belt 2, while the remaining waste slides off the conveyor belt 2. When the NdFeB waste moves to below the magnetic plate 10, due to the gradual expansion of the magnetic plate 10 and the inner wall of the conveyor belt 2, the NdFeB waste of different sizes falls to different positions below the conveyor belt 2 due to the gravity of the NdFeB waste of different sizes and the adsorption force between the NdFeB waste of different sizes and the magnetic plate 10, thus completing the screening of the NdFeB waste and the other waste mixed in with it.

[0051] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
