Description

Technical Field

[0001] This utility model relates to the field of waste neodymium iron boron magnet processing technology, specifically a waste neodymium iron boron magnet crusher. Background Technology

[0002] Crushing can fully extract the useful components from waste NdFeB magnets, reducing resource waste. Therefore, a crusher is needed to crush waste NdFeB magnets.

[0003] Existing waste NdFeB magnet crushers do not classify the waste NdFeB magnets before crushing, which leads to larger waste NdFeB magnets causing wear and tear on the equipment, thus shortening the crusher's lifespan and making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a waste neodymium iron boron magnet crusher.

[0005] The technical problem solved by this utility model is that the existing waste NdFeB magnet crusher does not classify the waste NdFeB magnets before crushing, which makes the larger-sized waste NdFeB magnets easy to cause wear and tear on the equipment, thus shortening the life of the crusher and making it inconvenient to use.

[0006] This utility model can be achieved through the following technical solution: a waste NdFeB magnet crusher, including a first crusher and a second crusher, with a grading mechanism installed on the first crusher. The grading mechanism includes a grading box fixed on the first crusher, with a screening screen plate vertically and elastically slidably connected between the two inner side walls of the grading box. A vibrating motor for driving the screening screen plate to reciprocate is fixedly installed on one side of the grading box, and a conveying inclined pipe corresponding to the screening screen plate is fixedly connected to the other side of the grading box. The end of the conveying inclined pipe away from the grading box is connected to the second crusher. The discharge port of the bottom wall of the grading box corresponds to the feed port of the top wall of the first crusher. By pre-grading the waste NdFeB magnets, more suitable processing methods can be adopted for magnets of different sizes, thereby improving the efficiency of the entire recycling process.

[0007] A further technical improvement of this utility model is that an electric telescopic rod is fixedly installed on the grading box, and a sealing plate for sealing the inlet of the conveying inclined tube is fixedly installed at the output end of the electric telescopic rod.

[0008] A further technical improvement of this utility model is that: the inner cavity of the grading box and the two sides of the discharge port are symmetrically and elastically slidably connected with two support plates for blocking the discharge port. The inner cavities of the two support plates are fitted with two second electromagnetic blocks with opposite magnetic poles. By disconnecting the power supply of the two second electromagnetic blocks, the two support plates can be moved in opposite directions, thereby facilitating the discharge of smaller waste neodymium iron boron magnets into the inner cavity of the first crusher for crushing.

[0009] A further technical improvement of this utility model is that: the inner cavity of the grading box is provided with a dustproof component, which includes two mounting plates symmetrically and slidably connected to the top of the inner cavity of the grading box for sealing the inlet of the feed hopper. An atomizing nozzle assembly is fixedly installed at the bottom of the mounting plate. A water pump is fixedly installed on the top of the grading box. The outlet of the water pump is connected to two telescopic hoses through a three-way pipe. The two telescopic hoses are respectively connected to the atomizing nozzle assemblies at the bottom of the two mounting plates. By driving the water pump, the atomizing nozzle assemblies can be used to reduce dust on the waste neodymium iron boron magnets during the grading process.

[0010] A further technical improvement of this utility model is that: two first electromagnetic blocks with opposite magnetic poles are fitted into the inner cavities of the two mounting plates; by turning on the power supply to the two first electromagnetic blocks, the two mounting plates move towards each other; by turning off the power supply to the two first electromagnetic blocks, the two mounting plates move in opposite directions.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model separates waste NdFeB magnets of different sizes by using a vibrating screen with a screening mesh, ensuring that the waste NdFeB magnets entering the crushing equipment are of uniform size. Through pre-grading, more suitable processing methods can be adopted for waste NdFeB magnets of different sizes, thereby improving the efficiency of the entire recycling process. This not only reduces equipment wear and extends the service life of the crusher, but also makes it easier to use.

[0013] 2. Before classifying waste NdFeB magnets, this utility model uses the power supply of two first electromagnetic blocks to make two sealing plates slide towards each other. The movement of the two sealing plates facilitates the sealing of the inlet of the feed hopper, preventing dust from overflowing during the classification process. Furthermore, during the classification of waste NdFeB magnets, the water pump facilitates the dust suppression of dust generated during the classification process through the atomizing nozzle assembly, thus making it easier for workers to use.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figure 1-6 As shown, this embodiment provides a technical solution: a waste NdFeB magnet crusher, including a first crusher 1 for crushing smaller waste NdFeB magnets and a second crusher 2 for crushing larger waste NdFeB magnets.

[0028] A grading mechanism is provided on the first crusher 1. The grading mechanism includes a grading box 3 fixed on the first crusher 1. A feed hopper 31 is fixedly connected to the grading box 3. A discharge port 33 is opened through the bottom wall of the first crusher 1. The discharge port 33 of the bottom wall of the first crusher 1 corresponds to the feed port of the top wall of the first crusher 1. A screening screen plate 35 is vertically and elastically slidably connected between the two inner side walls of the grading box 3. A vibration motor 34 for driving the screening screen plate 35 to reciprocate is fixedly installed on one side of the grading box 3. Springs, rubber pads or other elastic materials are used as connecting parts in the inner cavity of the grading box 3 to ensure that the screening screen plate 35 can slide freely in the vertical direction. The elastic elements are installed in the inner cavity of the grading box 3 to ensure that they can be evenly distributed around the screening screen plate 35 and provide stable support for the screening screen plate 35.

[0029] More specifically, the front of the grading box 3 is equipped with a transparent observation window, which makes it easier for staff to observe the internal conditions.

[0030] The other side of the grading box 3 is fixedly connected to a conveying inclined pipe 32 corresponding to the screening screen plate 35. The end of the conveying inclined pipe 32 away from the grading box 3 is connected to the second crusher 2. The inner cavity of the grading box 3 is provided with a sealing component to block the inlet of the conveying inclined pipe 32.

[0031] The blocking assembly includes a sliding groove 37 that is opened in the inner cavity of the classifier 3 and communicates with the conveying inclined tube 32. The inner cavity of the sliding groove 37 is slidably connected to a blocking plate 38 for blocking the inlet of the conveying inclined tube 32. An electric telescopic rod 36 for driving the blocking plate 38 to slide vertically is fixedly installed on the classifier 3.

[0032] More specifically, before the waste NdFeB magnets are graded, the sealing plate 38 is used to seal the conveying inclined pipe 32. After the waste NdFeB magnets are graded, the upward movement of the sealing plate 38 facilitates the waste NdFeB magnets to enter the inner cavity of the second crusher 2 through the conveying inclined pipe 32 for crushing.

[0033] Both sides of the blocking plate 38 are fixed with sliders 4 that are slidably connected to the inner wall of the sliding groove 37. Two trigger switches 39 corresponding to sliders 4 are symmetrically fixed at the top of both sides of the inner wall of the sliding groove 37. Two receiving grooves 314 are symmetrically opened in the inner cavity of the classifier 3 on both sides of the discharge port 33. Two support plates 315 for blocking the discharge port 33 are elastically slidably connected in the inner cavity of the two receiving grooves 314. The support plates 315 are slidably connected to the inner cavity of the receiving grooves 314 by springs. Two second electromagnetic blocks 316 with opposite magnetic poles are fitted into the inner cavity of the two support plates 315. The two second electromagnetic blocks 316 are electrically connected to the trigger switches 39. The power supply to the two second electromagnetic blocks 316 is disconnected by the slider 4 contacting the trigger switches 39, thereby facilitating the reset of the two support plates 315.

[0034] Two mounting plates 310 for sealing the inlet of the feed hopper 31 are symmetrically slidably connected to the top of the inner wall of the grading box 3. An atomizing nozzle assembly 311 is fixedly installed at the bottom of the mounting plate 310. A reserved space is formed between the atomizing nozzle assembly 311 and the screening screen plate 35. The reserved space is set to avoid damage to the atomizing nozzle assembly 311 caused by the reciprocating vibration of the waste neodymium iron boron magnets on the screening screen plate 35.

[0035] Two first electromagnetic blocks 312 with opposite magnetic poles are fitted into the inner cavities of the two mounting plates 310. By connecting the two first electromagnetic blocks 312, the two mounting plates 310 slide towards each other, which facilitates the sealing of the inlet of the feed hopper 31. By sealing it, the dust and other impurities generated during the reciprocating vibration of the waste NdFeB magnets are prevented from overflowing. A water pump 313 is fixedly installed on the classifier 3. The outlet of the water pump 313 is connected to two telescopic hoses through a three-way pipe. The two telescopic hoses are respectively connected to the atomizing nozzle group 311 at the bottom of the two mounting plates 310. Driven by the water pump 313, the atomizing nozzle group 311 can be used to suppress dust and other impurities generated during the reciprocating vibration of the waste NdFeB magnets.

[0036] In use, a measured amount of waste NdFeB magnets to be crushed is fed into the inner cavity of the grading box 3 through the feed hopper 31. The waste NdFeB magnets fall onto the screening screen plate 35 under gravity. Driven by the vibration motor 34, the screening screen plate 35 vibrates back and forth. The reciprocating vibration of the screening screen plate 35 facilitates the grading of waste NdFeB magnets of different sizes. The smaller waste NdFeB magnets that conform to the mesh size of the screening screen plate 35 will fall onto the two support plates 315, while the larger waste NdFeB magnets that do not conform to the mesh size of the screening screen plate 35 will remain on the screening screen plate 35.

[0037] Before classifying the waste NdFeB magnets, the power supply to the two first electromagnetic blocks 312 is turned on to make the two sealing plates 38 slide towards each other. The movement of the two sealing plates 38 facilitates the sealing of the inlet of the feed hopper 31, preventing dust from overflowing during the classification process. Furthermore, during the classification of the waste NdFeB magnets, the water pump 313 drives the atomizing nozzle group 311 to suppress the dust generated during the classification process, thus facilitating the use by the staff.

[0038] After the waste NdFeB magnets are graded, the power supply to the vibration motor 34 is disconnected first, and then the power supply to the first electromagnetic block 312 is disconnected to reset the two sealing plates 38. The reset of the sealing plates 38 facilitates the subsequent use of the equipment. Then, the electric telescopic rod 36 is shortened. The shortening of the electric telescopic rod 36 causes the sealing plates 38 to move upward. The upward movement of the sealing plates 38 exposes the inlet of the conveying inclined pipe 32. Through the guiding effect of the screening screen plate 35, larger waste NdFeB magnets can enter the inner cavity of the second crusher 2 through the conveying inclined pipe 32, which facilitates their crushing.

[0039] The upward movement of the sealing plate 38 causes the slider 4 to contact the trigger switch 39, which cuts off the power supply to the two second electromagnetic blocks 316, causing the two support plates 315 to move in opposite directions. The movement of the two support plates 315 causes the smaller waste neodymium iron boron magnets to enter the inner cavity of the first crusher 1 for crushing.

[0040] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
