Description

Technical Field

[0001] This utility model relates to the field of magnetic materials technology, and in particular to a screening and cleaning device for neodymium iron boron magnetic materials. Background Technology

[0002] Neodymium iron boron (NdFeB) is a type of magnet with excellent magnetic properties, hence its nickname "King of Magnets." NdFeB is primarily composed of elements such as neodymium, iron, and boron. It is characterized by its hardness and brittleness. Before electroplating, NdFeB magnetic materials require surface treatment, mainly including screening and cleaning.

[0003] Existing magnetic material screening and cleaning equipment typically involves pouring a pile of mixed materials into the equipment, using an adsorption device inside the equipment to adsorb the magnetic sand within the pile, and then using a blower to remove non-magnetic materials. However, the magnetic materials remaining after impurity removal are still adsorbed inside the equipment and need to be manually removed and placed in a cleaning device for further cleaning. This process is cumbersome and lacks automation. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a screening and cleaning device for neodymium iron boron magnetic materials, which has the advantages of high automation and high screening efficiency, in order to solve the problem mentioned in the background art that the magnetic materials after impurity removal are still adsorbed in the device, requiring manual removal and placement into the cleaning device for cleaning, which is a cumbersome process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening and cleaning device for neodymium iron boron magnetic materials, comprising a support shell, an observation window on the front of the support shell, a feed inlet installed at the upper end of the support shell, a crushing roller installed inside the feed inlet, a double screen plate installed inside the support shell, the double screen plate being fixed directly below the feed inlet, a blowing mechanism installed on the side of the double screen plate, a feeding belt installed at the lower end of the double screen plate, and a spraying mechanism installed on the upper side of the feeding belt;

[0006] The bottom of the support housing is provided with a bottom water tank, which is connected to the spraying mechanism, and the front of the support housing is provided with a control panel.

[0007] The dual screening plate includes a first slide and a second slide. Adsorption magnetic plates are fixed at the bottom of the first slide and the second slide, and a transmission belt is fixed on the upper part of the first slide and the second slide. The transmission belt is provided with uniformly distributed scrapers.

[0008] Preferably, the crushing roller is provided with crushing teeth, and a drive motor is fixed at the end of the crushing roller, which drives the crushing roller to rotate in opposite directions.

[0009] Preferably, a side plate is provided on the left side of the first slide and the second slide, the blowing mechanism includes a blower and a dust collection chamber, the blower has an air outlet at its end, the air outlet is provided on the side plate, and the dust collection chamber is fixed to the right side of the first slide and the second slide.

[0010] Preferably, the spraying mechanism includes a water pump, which is fixed to the side of the bottom water tank. A water delivery pipe is installed at the end of the water pump, and a spray head is connected to the end of the water delivery pipe. The spray head is positioned directly above the feeding belt.

[0011] Preferably, a filter screen is provided in the bottom water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This screening and cleaning device for NdFeB magnetic materials can initially crush the agglomerated NdFeB magnetic materials through the crushing roller, which facilitates subsequent screening and cleaning. Through the double screening plate and the blowing mechanism, impurities in the NdFeB magnetic materials can be removed. Specifically, after the NdFeB magnetic materials are crushed, they fall into the first slide and slide down the first slide under the action of gravity. During the sliding process, under the action of the adsorption magnetic plate, the NdFeB is adsorbed in the slide, while other impurities are blown into the dust collection chamber by the blower, thus achieving the separation of impurities. At the same time, the scraper, driven by the transmission belt, scrapes the NdFeB in the first slide into the second slide for a second round of screening, resulting in a good screening effect. After screening, the NdFeB magnetic materials are cleaned by the feeding belt and the spraying mechanism. The water after cleaning flows into the bottom water tank and is collected for reuse, resulting in a high degree of automation. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a screening and cleaning device for neodymium iron boron magnetic materials, comprising a support housing 1, an observation window 11 on the front of the support housing 1, a feed inlet 3 installed at the upper end of the support housing 1, a crushing roller 2 disposed inside the feed inlet 3, the crushing roller 2 having crushing teeth 21 disposed on the crushing roller 2, a drive motor fixed at the end of the crushing roller 2, which drives the crushing roller 2 to rotate in opposite directions, and a double screening plate 4 disposed inside the support housing 1, the double screening plate 4 including a first slide rail 41 and a second slide rail 42, the bottom of the first slide rail 41 and the second slide rail 42 being fixed An adsorption magnetic plate 43 is fixed. A transmission belt 44 is fixed on the upper part of the first slide rail 41 and the second slide rail 42. A scraper 45 is evenly distributed on the transmission belt 44. A double screen plate 4 is fixed directly below the feed inlet 3. A blowing mechanism 5 is installed on the side of the double screen plate 4. A feeding belt 6 is installed at the lower end of the double screen plate 4. A spraying mechanism 7 is installed on the upper side of the feeding belt 6. A bottom water tank 8 is set at the bottom of the support shell 1. A filter screen 81 is set in the bottom water tank 8. The bottom water tank 8 is connected to the spraying mechanism 7. A control panel 9 is set on the front of the support shell 1.

[0022] Based on the above structural features, during operation, the crushing teeth 21 moving in opposite directions on the crushing roller 2 can initially crush the agglomerated NdFeB magnetic material, facilitating subsequent screening and cleaning. The double screening plate 4, in conjunction with the blowing mechanism 5, can remove impurities from the NdFeB magnetic material. Specifically, after the NdFeB magnetic material is crushed, it falls into the first slide 41 and slides down under gravity. During this sliding process, under the action of the adsorption magnetic plate 43, the NdFeB is adsorbed within the slide, while other impurities are partially absorbed. Blower 51 blows into dust collection chamber 53 to separate impurities. At the same time, scraper 45, driven by drive belt 44, scrapes the neodymium iron boron in first slide 41 into second slide 42 for a second round of screening. The screening effect is good. After screening, the neodymium iron boron magnetic material is cleaned by feeding belt 6 in conjunction with spraying mechanism 7. The water after cleaning flows into bottom water tank 8 and is collected for secondary use. The degree of automation is high. Filter screen 81 can isolate impurities in the water and prevent them from being drawn out by water pump 71 and clogging water supply pipe 72.

[0023] Please see Figures 1-5 The first slide 41 and the second slide 42 are provided with side plates 46 on the left side. The blowing mechanism 5 includes a blower 51 and a dust collection chamber 53. The blower 51 is connected to an air outlet 52 at its end. The air outlet 52 is provided on the side plate 46. The dust collection chamber 53 is fixed to the right side of the first slide 41 and the second slide 42.

[0024] In combination with the above structural features, when this utility model is in operation, the blower 51 is started, and high-pressure air is blown out from the air outlet 52 that is evenly distributed on the side plate 46 through the pipe, blowing the non-magnetic materials that have not been adsorbed by the magnetic plate 43 into the dust collection chamber 53.

[0025] Please see Figures 1-5 The spraying mechanism 7 includes a water pump 71, which is fixed to the side of the bottom water tank 8. A water delivery pipe 72 is installed at the end of the water pump 71, and a spray head 73 is connected to the end of the water delivery pipe 72. The spray head 73 is located directly above the feeding belt 6.

[0026] In accordance with the above structural features, when this utility model is in operation, the water pump 71 draws water out of the bottom water tank 8 and pumps it through the water delivery pipe 72 to the spray head 73 for spraying, thereby cleaning the magnetic material.

[0027] Working principle: When in use, the crushing teeth 21 moving in opposite directions on the crushing roller 2 can initially crush the agglomerated NdFeB magnetic material, which is convenient for subsequent screening and cleaning. The double screen plate 4 and the blowing mechanism 5 can remove impurities from the NdFeB magnetic material. After screening, the NdFeB magnetic material is cleaned by the feeding belt 6 and the spraying mechanism 7. The water after cleaning will flow into the bottom water tank 8 and be collected for secondary use. The automation level is high. The filter screen 81 can isolate impurities in the water and prevent them from being pumped out by the water pump 71 and clogging the water supply pipe 72.
