Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron filings collection technology, specifically a device for treating waste liquid from grinding with neodymium iron boron strong magnets. Background Technology
[0002] Neodymium iron boron (NdFeB) strong magnets are composed of three elements: neodymium, iron, and boron. They have strong magnetism. The waste liquid generated during the polishing process of NdFeB strong magnets contains iron filings that fall off. These iron filings have high value, and if they are not treated effectively, they will cause resource waste. Therefore, they usually need to be filtered and recycled.
[0003] However, traditional neodymium iron boron strong magnet grinding waste liquid treatment devices generally use filter screens to collect iron filings when filtering and recycling them. Iron filings tend to accumulate on the surface of the filter screen, which may clog the mesh and affect the normal filtration of waste liquid. This requires frequent manual cleaning of the iron filings accumulated on the filter screen to ensure continuous filtration. The operation is cumbersome, the iron filings are inconvenient to recycle, and the labor costs are greatly increased.
[0004] To address these issues, we offer a neodymium iron boron (NdFeB) strong magnet grinding waste liquid treatment device. Utility Model Content
[0005] 1) Technical problems to be solved
[0006] This utility model proposes a waste liquid treatment device for grinding neodymium iron boron strong magnets. Through the cooperation between the recovery plate, the first telescopic rod, the second telescopic rod, the push plate, and the collection box, it solves the problems of traditional waste liquid treatment devices for grinding neodymium iron boron strong magnets, which are cumbersome to operate, inconvenient to recover iron filings, and have high labor costs when filtering and recovering iron filings from neodymium iron boron strong magnets.
[0007] (ii) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a waste liquid treatment device for grinding neodymium iron boron magnets, comprising a discharge channel, wherein multiple sets of iron filings recovery mechanisms are arranged within the discharge channel, and the iron filings recovery mechanisms include:
[0009] A recovery plate is slidably connected in the drain channel, and an iron plate is connected inside the recovery plate, with the upper surface of the iron plate flush with the upper surface of the recovery plate.
[0010] The first telescopic rod has two connecting rods connected to its driving end. The connecting rods are connected to the upper end of the recovery plate, and the side end of the connecting rod is provided with a guide slope.
[0011] The second telescopic rod has a push plate connected to its drive end. The push plate has two bent ends and can be slidably connected to the upper end of the recovery plate.
[0012] A collection box is located at the outer end of the drain channel, and a rectangular slot is provided on the side of the collection box, which is located at the side end of the push plate.
[0013] Furthermore, a support frame is connected to the lower end of the drainage channel, and the support frames are arranged sequentially from high to low, with the drainage channel being inclined.
[0014] Furthermore, the lower end of the recovery plate is inclined so that it can fit against the bottom plate of the drain channel.
[0015] Furthermore, the drain channel, recovery plate, connecting rod, push plate, and collection box are all made of high-strength insulating engineering plastics.
[0016] Furthermore, the scrap metal recycling mechanism also includes a fixed frame and a fixed plate. The fixed frame is connected to the upper end of the drain channel, the first telescopic rod is connected to the side end of the fixed frame, the fixed plate is connected to the side end of the drain channel, and the second telescopic rod is connected to the upper end of the fixed plate.
[0017] Furthermore, a tray is connected to the side end of the drain channel, the collection box is placed on the upper end of the tray, a connecting strip is connected to the upper end of the drain channel, the connecting strip is located at the side end of the push plate, and a downward slope is provided at the side end of the connecting strip.

A fixed frame is connected to the upper end of the drainage channel. A third telescopic rod is connected inside the fixed frame. The driving end of the third telescopic rod is connected to the adjusting valve plate.
[0019] (iii) Beneficial effects:
[0020] Compared with existing technologies, this neodymium iron boron strong magnet grinding waste liquid treatment device has the following advantages:
[0021] I. This neodymium iron boron (NdFeB) strong magnet grinding waste liquid treatment device features a recovery plate. Waste liquid flows through a drain channel. When iron filings from the NdFeB strong magnets pass over the recovery plate, their magnetic properties cause them to adhere to the plate, thus filtering the iron filings from the waste liquid. The device is equipped with a first telescopic rod and a second telescopic rod. The first telescopic rod periodically raises the recovery plate, and then the second telescopic rod activates, causing a pusher plate to move across the surface of the recovery plate, pushing the iron filings adsorbed on the plate into a collection box. This allows the device to automatically filter and collect iron filings from the waste liquid without frequent manual cleaning. Compared to traditional filter screens, this method is simpler, avoids clogging, and significantly saves labor costs.
[0022] II. This neodymium iron boron strong magnet grinding waste liquid treatment device is equipped with a regulating valve plate. The No. 3 telescopic rod can drive the regulating valve to move in the drain channel, thereby changing the gap between the lower end of the regulating valve plate and the drain channel. This allows the flow rate of the waste liquid in the drain channel to be controlled within a suitable range, so that the waste liquid flows through the recovery plate in a shallow layer (waste liquid depth within 3 cm). This allows the iron filings in the waste liquid to better contact the iron plate, thereby improving the filtration quality of the iron filings in the waste liquid. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0032] The No. 1 telescopic rod 4, the No. 2 telescopic rod 6, and the No. 3 telescopic rod 16 in this utility model are all common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.
[0033] like Figure 1-6 As shown, this utility model provides a technical solution: a neodymium iron boron strong magnet grinding waste liquid treatment device, including a drain channel 1, a support base 9 connected to the lower end of the drain channel 1, the support base 9 is used to support and fix the drain channel 1, the support base 9 are arranged sequentially from high to low, so that the drain channel 1 is inclined, the waste liquid enters from the high end of the drain channel 1 and is discharged from the low end.
[0034] Multiple sets of iron filings recycling mechanisms are installed in the drainage channel 1. The iron filings recycling mechanism includes: recycling plate 2, telescopic rod 4, telescopic rod 6, and collection box 8. The recycling plate 2 is slidably connected in the drainage channel 1. The lower end of the recycling plate 2 is inclined and can fit against the bottom plate of the drainage channel 1, so as to prevent iron filings from being hidden in the connection gap between the two.
[0035] An iron plate 3 is connected inside the recycling plate 2. The upper surface of the iron plate 3 is flush with the upper surface of the recycling plate 2, so that the pusher 7 will not be blocked by the iron plate 3 when it moves on the recycling plate 2. The drive end of the first telescopic rod 4 is connected to two connecting rods 5, which are connected to the upper end of the recycling plate 2. The side end of the connecting rod 5 is provided with a guide slope. When the waste liquid impacts the connecting rod 5, under the action of its guide slope, the waste liquid can move towards the middle section of the recycling plate 2 and towards the iron plate 3, so that the waste liquid can better contact the iron plate 3. The drive end of the second telescopic rod 6 is connected to the pusher 7. The two ends of the pusher 7 are set to be bent to avoid pushing iron filings. When the iron filings are moved out from both sides, the push plate 7 can slide and connect to the upper end of the recycling plate 2. The collection box 8 is located at the outer end of the drain channel 1. A rectangular slot is opened on the side end of the collection box 8. The rectangular slot is located on the side end of the push plate 7. In this way, the push plate 7 can push the iron filings into the collection box 8. The iron filings recycling mechanism also includes a fixing frame 10 and a fixing plate 11. The fixing frame 10 is connected to the upper end of the drain channel 1. The first telescopic rod 4 is connected to the side end of the fixing frame 10 to fix the first telescopic rod 4. The fixing plate 11 is connected to the side end of the drain channel 1. The second telescopic rod 6 is connected to the upper end of the fixing plate 11 to fix the second telescopic rod 6.
[0036] The drain channel 1, recovery plate 2, connecting rod 5, push plate 7, and collection box 8 are all made of high-strength insulating engineering plastic to prevent iron filings from being attracted by the neodymium iron boron magnet. A support plate 12 is connected to the side of the drain channel 1, and the collection box 8 is placed on the upper end of the support plate 12 to support the collection box 8. A connecting strip 13 is connected to the upper end of the drain channel 1. The connecting strip 13 is located on the side of the push plate 7, and a downward slope is provided on the side of the connecting strip 13 to facilitate the entry of iron filings on the recovery plate 2 into the collection box 8.
[0037] A regulating valve plate 14 is slidably connected inside the drain channel 1. The regulating valve plate 14 is located at the side end of the highest recovery plate 2. A fixed frame 15 is connected to the upper end of the drain channel 1. A third telescopic rod 16 is connected inside the fixed frame 15. The driving end of the third telescopic rod 16 is connected to the regulating valve plate 14. The third telescopic rod 16 is used to adjust the height of the regulating valve plate 14, thereby controlling the flow rate of waste liquid in the drain channel 1.
[0038] Working principle: During use, waste liquid enters from the high end of drain channel 1. The position of regulating valve plate 14 is adjusted using telescopic rod 16 (number 3) to control the waste liquid flow within a suitable range (waste liquid depth within 3 cm). The waste liquid flows within drain channel 1. When the waste liquid flows past recovery plate 2, the iron filings from the neodymium iron boron magnet are attracted to the iron plate 3 due to their magnetism. Telescopic rod 4 (number 1) is activated periodically (the activation of all telescopic rods 4 is not simultaneous), raising recovery plate 2 to its highest position via connecting rod 5 (e.g., ...). Figure 4 At this time, the second telescopic rod 6 starts and drives the push plate 7 to move. The push plate 7 moves on the upper surface of the recycling plate 2, thereby pushing the adsorbed iron filings. As the push plate 7 pushes, the iron filings will detach from the iron plate 3, and then move from the recycling plate 2 to the connecting strip 13, and finally fall into the collection box 8. After completing this series of operations, the second telescopic rod 6 drives the push plate 7 to reset, and the first telescopic rod 4 drives the recycling plate 2 to reset.
