DETAILED DESCRIPTION
[0016] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.
[0017] Embodiment 1: A rare earth metal powder preparation device, such as Figure 1-4As shown, it includes a mounting frame 100, a material holding plate 101, an electric slide rail 200, a scraper 2 and a drying box 3. The material holding plate 101 is installed in the mounting frame 100, and the drying box 3 for collecting rare earth metal powder is installed on both the front and rear sides of the material holding plate 101. Electric slide rails 200 are installed in parallel on the left and right sides of the mounting frame 100. The scraper 2 for scraping the rare earth metal powder to the drying box 3 is connected between the electric slide rails 200. The material holding plate 101 is provided with a water leakage hole 102. When the rare earth metal powder on the material holding plate 101 has too much moisture, the moisture can flow out through the water leakage hole 102. The drying box 3 is provided with a drying mechanism for drying the rare earth metal powder. The drying mechanism includes a cylinder 9 and an electric heating partition 10. The cylinder 9 is installed on both sides of the drying box 3. The telescopic end of the cylinder 9 is connected to the electric heating partition 10. The electric heating partition 10 is slidably inserted into the drying box 3. Initially, the telescopic rod of the cylinder 9 is in an extended state so that the electric heating partition 10 does not block the entrance of the drying box 3, so as to facilitate the collection of rare earth metal powder. When the rare earth metal powder in the drying box 3 is full, the telescopic rod of the cylinder 9 is controlled to shorten, thereby driving the electric heating partition 10 to be inserted into the rare earth metal powder in the direction of the drying box 3 and separate the metal powder into multiple thin layers. Then, the electric heating partition 10 is turned on to heat the rare earth metal powder in the drying box 3 to accelerate the drying of the rare earth metal powder.
[0018] Embodiment 2: Based on embodiment 1, Figure 5-Figure 7 As shown, it also includes an extrusion mechanism, which includes a counterweight 4, a pressure plate 5, a hinged plate 6, a spring 7 and a plug rod 8. The upper parts of the left and right ends of the mounting frame 100 are slidably installed with a pressure plate 5 through a connecting plate 50. A counterweight 4 is installed above the pressure plate 5. A hinged plate 6 is connected between the counterweight 4 and the connecting plate 50. A through hole 80 is opened in the middle of the scraper 2 and a plug rod 8 is slidably inserted in the hole. The plug rod 8 and the two end surfaces of the scraper 2 are connected with springs 7, and the plug rod 8 is perpendicular to the hinged plate 6. When the scraper 2 moves toward the pressure plate 5, the plug rod 8 will gradually be squeezed and contacted with the upper half of the hinged plate 6, thereby squeezing the hinged plate 6 to rotate and fold it. It should be noted that the spring The elastic force of spring 7 is sufficient to enable the insertion rod 8 to lift the hinged plate 6 and rotate it, thereby lifting the pressure plate 5 until the scraper 2 pushes the rare earth metal powder to the bottom of the pressure plate 5, so as to facilitate the subsequent water extraction of the rare earth metal powder. As the scraper 2 continues to move toward the pressure plate 5, the elastic force of the spring 7 is insufficient to prevent the scraper 2 from continuing to move, and the rare earth metal powder can continue to be pushed to the bottom of the pressure plate 5 through the scraper 2. When the insertion rod 8 is away from the pressure plate 5, the insertion rod 8 no longer squeezes the hinged plate 6 under the resetting action of the spring 7, and the hinged plate 6 no longer rotates and folds, and thus the pressure plate 5 is no longer lifted. Under the action of the counterweight block 4, the pressure plate 5 squeezes the rare earth metal powder on the material holding plate 101 downward to initially squeeze out the water.
[0019] like Figure 8 As shown, it also includes a pushing assembly, which includes a pushing plate 141, a hinged rod 14 and a guide rail 142. The scraper 2 is provided with a first placement groove 201 on the left and right sides, and two hinged rods 14 are rotatably connected in the groove. Push plates 141 are provided on the front and rear sides of the scraper 2. The push plate 141 is installed with a guide rail 142. The end of the hinged rod 14 is slidably connected to the push plate 141 through the guide rail 142. It also includes a motor 140 and a rotating rod 143. A mounting groove 202 is provided in the middle of the scraper 2, and the motor 140 is installed in the mounting groove 202. The rotating shaft of the motor 140 is keyed to the rotating rod 143. A second placement groove 203 for accommodating the rotating rod 143 is provided at the lower part of the scraper 2. Both ends of the rotating rod 143 are connected to the The guide rail 142 is slidably connected; when the motor 140 is started, it drives the hinged rod 14 to slide along the outer end of the guide rail 142, and then pushes the push plate 141 toward the front and rear ends of the material holding plate 101, so as to push the rare earth metal powder into the drying box 3. When the motor 140 rotates in the opposite direction, it will drive the rotating rod 143 to rotate, and then make the rotating rod 143 slide in the opposite direction along the guide rail 142, and then drive the hinged rod 14 to rotate in the opposite direction, so that the hinged rod 14 rotates into the first placement groove 201, and the rotating rod 143 rotates into the second placement groove 203; when the push plate 141 is extended, the angle between the scraper 2 and the hinged rod 14 is an acute angle, so that when the motor 140 rotates in the opposite direction, the push plate 141 can be smoothly retracted into the first placement groove 201 and the second placement groove 203.
[0020] like Fig. 9 and Fig.10 As shown, it also includes a lifting baffle 12, and the lifting baffle 12 is installed at the discharge ports at the front and rear ends of the material holding plate 101. It also includes a connecting rod 11 and a guide rod 13, and the connecting rod 11 is connected to both sides of the electric heating partition 10, and the lifting baffle 12 is installed with a guide rod 13 that is pressed and guided by the connecting rod 11; when the connecting rod 11 moves to the left, it will squeeze the guide rod 13, so that the guide rod 13 is lifted upward, and then the guide rod 13 pushes the lifting baffle 12 to move upward, so that the lifting baffle 12 no longer blocks the discharge ports at both ends of the material holding plate 101, so that the pushing assembly can push the rare earth metal powder into the drying box 3, so as to facilitate the powder drying operation.
[0021] like Fig.11 As shown, a rolling roller 15 is also included. The rolling roller 15 is installed at the discharge port at the lower part of the drying box 3. The rolling roller 15 is used to further crush the block rare earth metal powder in the drying box 3 to form powder that falls from the discharge port.
