Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron (NdFeB) production technology, specifically to a dehydration device for sheet materials used in NdFeB production. Background Technology

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are tetragonal crystals formed by neodymium, iron, and boron. During the production process, the whole piece of neodymium iron boron needs to be cut and polished. The polished sheet material needs to be cooked and degummed. The degummed material forms small sheet material, which then needs to be dehydrated and screened.

[0003] In the process of dehydrating neodymium magnet sheet materials, centrifugation and other methods are often used. This method can remove most of the water, but some water will still adhere to the surface of the neodymium magnet sheet materials, which still needs to be dried or sun-dried, making it inconvenient for timely processing of neodymium magnet sheet materials. Utility Model Content

[0004] The purpose of this invention is to provide a dehydration device for sheet materials used in NdFeB production, which solves the problem that some water still adheres to the surface of the NdFeB magnet sheet materials after dehydration in the prior art, affecting the timeliness of processing.

[0005] This utility model provides the following technical solution: a dehydration device for sheet materials used in NdFeB production, comprising a dehydration treatment chamber, a sawdust dehydration mechanism on the dehydration treatment chamber, and a dust reduction mechanism on the outer wall of the dehydration treatment chamber.

[0006] The sawdust dewatering mechanism includes a base, a rotating seat, a stepper motor, a connecting seat, and a connecting rod. The rotating seat is rotatably connected to the bottom of the inner wall of the dewatering chamber. A stirring fin is fixedly installed on the outer wall of the rotating seat. The stepper motor is fixedly installed at the center of the bottom of the dewatering chamber. The output shaft of the stepper motor extends into the inner cavity of the dewatering chamber and is fixedly connected to the bottom of the rotating seat. The connecting rod is fixedly installed on the inner wall of the dewatering chamber. A fixed frustum is fixedly installed at the end of the connecting rod away from the inner wall of the dewatering chamber. The bottom of the fixed frustum is movably connected to the top of the rotating seat. A middle platform is fixedly installed on the top of the fixed frustum. The connecting seat is fixedly installed at the bottom of the dewatering chamber.

[0007] As a preferred embodiment of the above technical solution, a protruding seat is fixedly installed on the top of the base, and the number of the protruding seats is set to two. A track rod is fixedly installed between the adjacent sides of the two protruding seats. A sliding square seat is slidably connected to the outer wall of the track rod. The connecting seat is fixedly installed on the top of the sliding square seat. Elastic members are fixedly installed on both sides of the sliding square seat. The end of the elastic member away from the sliding square seat is fixedly connected to the side of the protruding seat.

[0008] As a preferred embodiment of the above technical solution, the base has a notch on its front side, and a drive motor is fixedly installed on the top of the inner wall of the notch. The output shaft of the drive motor extends to the top of the dehydration chamber and is fixedly connected to a cam.

[0009] As a preferred embodiment of the above technical solution, an extension arm is fixedly installed on the front of the sliding seat, and a roller is rotatably connected to the right side of the extension arm. The outer wall of the roller is movably connected to the outer wall of the cam.

[0010] As a preferred embodiment of the above technical solution, the dust suppression mechanism includes a support ring, which is fixedly installed on the outer wall of the dehydration treatment chamber. A hollow ring is fixedly installed on the top of the support ring, and a strip mesh is fixedly installed on the inner wall of the hollow ring.

[0011] As a preferred embodiment of the above technical solution, a hollow connecting plate is fixedly connected to the right side of the hollow ring, a dust settling chamber is fixedly connected to the bottom of the hollow connecting plate, and a suction fan is fixedly connected to the bottom of the dust settling chamber.

A cover plate is movably inserted into the right side of the dust settling chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a dehydration chamber design that allows operators to simultaneously add dried sawdust and neodymium magnet flakes into its inner cavity. A stepper motor drives a rotating seat, which in turn rotates the stirring blades, causing the sawdust and neodymium magnet flakes to tumble around a central platform. This ensures the sawdust fully absorbs moisture from the surface of the neodymium magnet flakes, followed by sieving of the neodymium magnet flakes, thus completing the dehydration process. This avoids the time-consuming problem of using drying or air-drying methods for dehydration, improving the timeliness of neodymium magnet flake processing. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a dehydration device for sheet materials used in NdFeB production, including a dehydration chamber 1, a sawdust dehydration mechanism 2 installed on the dehydration chamber 1, and a dust suppression mechanism 3 installed on the outer wall of the dehydration chamber 1. The sawdust dehydration mechanism 2 includes a base 21, a rotating seat 22, a stepper motor 24, a connecting seat 25, and a connecting rod 26. The rotating seat 22 is rotatably connected to the bottom of the inner wall of the dehydration chamber 1. A stirring fin 23 is fixedly installed on the outer wall of the rotating seat 22. The stepper motor 24 is fixedly installed at the center of the bottom of the dehydration chamber 1. The output shaft of the stepper motor 24 extends into the inner cavity of the dehydration chamber 1 and is fixedly connected to the bottom of the rotating seat 22. The connecting rod 26 is fixedly installed on the inner wall of the dehydration chamber 1, and the connecting rod 26 is located away from the inner wall of the dehydration chamber 1. A fixed truncated cone 261 is fixedly installed at one end. The bottom of the fixed truncated cone 261 is movably connected to the top of the rotating seat 22. A middle platform 262 is fixedly installed on the top of the fixed truncated cone 261. A connecting seat 25 is fixedly installed at the bottom of the dehydration chamber 1. First, dry sawdust and neodymium magnet sheet material are added to the inner cavity of the dehydration chamber 1 at the same time. The stepper motor 24 is controlled to drive the rotating seat 22 to rotate, and at the same time, the stirring blades 23 are driven to rotate. The sawdust and neodymium magnet sheet material are turned around the middle platform 262, so that the sawdust fully absorbs the moisture on the surface of the neodymium magnet sheet material. Then, the neodymium magnet sheet material is screened, thus completing the dehydration process. This avoids the problem of long time consumption when using drying or air drying methods for dehydration, and improves the timeliness of neodymium magnet sheet material processing.

[0023] As one implementation method in this embodiment, such as Figure 2 , Figure 3 As shown, a protruding seat 215 is fixedly installed on the top of the base 21. Two protruding seats 215 are provided. A track rod 216 is fixedly installed between adjacent sides of the two protruding seats 215. A sliding square seat 218 is slidably connected to the outer wall of the track rod 216. A connecting seat 25 is fixedly installed on the top of the sliding square seat 218. Elastic members 217 are fixedly installed on both sides of the sliding square seat 218. The end of the elastic member 217 away from the sliding square seat 218 is fixedly connected to the side of the protruding seat 215. A notch is provided on the front of the base 21. A drive motor 211 is fixedly installed on the top of the inner wall of the notch. The output shaft of the drive motor 211 extends to the top of the dehydration chamber 1 and is fixed. A cam 212 is connected to the sliding seat 218, and an extension arm 214 is fixedly installed on the front side. A roller 213 is rotatably connected to the right side of the extension arm 214. The outer wall of the roller 213 is movably connected to the outer wall of the cam 212. The drive motor 211 is controlled to work, which can drive the cam 212 to rotate. During the rotation of the cam 212, the roller 213 can be pushed to the left, which simultaneously causes the sliding seat 218 to slide to the left on the outer wall of the track rod 216. Through the initial elastic force of the elastic element 217, the sliding seat 218 can be driven to slide to the right to reset, which can cause the entire dewatering chamber 1 to vibrate, thereby increasing the rate at which sawdust absorbs moisture from the surface of neodymium magnet sheet material.

[0024] As one implementation method in this embodiment, such as Figure 1 , Figure 4 , Figure 5 As shown, the dust settling mechanism 3 includes a support ring 31, which is fixedly installed on the outer wall of the dehydration treatment chamber 1. A hollow ring 32 is fixedly installed on the top of the support ring 31, and a strip mesh 34 is fixedly installed on the inner wall of the hollow ring 32. A hollow connecting plate 33 is fixedly connected to the right side of the hollow ring 32, and a dust settling chamber 35 is fixedly connected to the bottom of the hollow connecting plate 33. A suction fan 354 is fixedly connected to the bottom of the dust settling chamber 35, and an internally threaded plate 351 is fixedly installed on the inner wall of the dust settling chamber 35. A non-woven fabric filter cover 352 is threadedly connected to the bottom of the internally threaded plate 351. A cover plate 353 is movably connected to the right side, controlling the operation of the suction fan 354. It can absorb and treat air and floating sawdust dust from the strip mesh 34. The air then passes through the hollow connecting plate 33 and enters the dust settling chamber 35. Through the design of the non-woven fabric filter cover 352, the air can be filtered to prevent sawdust dust from affecting the air quality inside the workshop. The cover plate 353 is made of elastic plastic and can be snapped onto the side of the dust settling chamber 35, making it easy for the operator to install and remove the cover plate 353, and then disassemble and clean the non-woven fabric filter cover 352.

[0025] Working principle: First, dry sawdust and neodymium magnet flakes are added to the inner cavity of the dehydration chamber 1. The stepper motor 24 is controlled to drive the rotating seat 22 to rotate, which in turn drives the stirring blades 23 to rotate, turning the sawdust and neodymium magnet flakes around the central platform 262. At the same time, the drive motor 211 is controlled to work, causing the entire dehydration chamber 1 to vibrate, so that the sawdust can fully absorb the moisture on the surface of the neodymium magnet flakes. Then, the neodymium magnet flakes are screened to remove the sawdust, thus completing the dehydration process.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
