[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-5 In existing metal powder preparation furnaces, metal materials need to be added into the furnace during the preparation of metal powder, which is not convenient for automatic feeding. In order to solve this technical problem, this embodiment discloses the following technical content;

[0027] A feeding device 5 is fixedly connected to the rear end of the upper surface of the top cover 2. The feeding device 5 is composed of a storage box 501, a flip cover 502, a feeding pipe 503, a second connecting plate 504, and a first discharging pipe 505. The upper surface of the storage box 501 is rotatably connected to the flip cover 502 by a hinge. The middle part of the flip cover 502 is fixedly connected to the feeding pipe 503. The outer side of the top end of the feeding pipe 503 is fixedly connected to the second connecting plate 504. The front end of the bottom of the storage box 501 is fixedly connected to the first discharging pipe 505. The lower inner surface of the storage box 501 is inclined towards the first discharging pipe 505. The bottom end of the first discharging pipe 505 is connected through to the rear end of the middle part of the top cover 2. A storage groove 6 is opened at the rear end of the lower surface of the top cover 2. A motor 7 is fixedly connected in the storage groove 6. The output shaft of the motor 7 is fixedly connected to a baffle 8. The upper surface of the baffle 8 is parallel to the lower surface of the top cover 2.

[0028] The second connecting plate 504 on the feed pipe 503 is connected to the device for conveying metal powder. The metal powder will enter the storage box 501. When the metal powder is fed from the storage box 501 into the preparation furnace body 1, the output shaft of the motor 7 controls the baffle 8 to rotate. Since the output shaft of the motor 7 and the baffle 8 are eccentrically connected, when the output shaft of the motor 7 rotates the baffle 8 to the other side, the first discharge pipe 505 can leak out. The metal powder can enter the preparation furnace body 1 through the first discharge pipe 505. The metal powder is stored in the storage box 501. When automatic feeding is required, the output end of the motor 7 rotates the baffle 8, which allows the metal powder to enter the preparation furnace body 1 through the first discharge pipe 505. The above steps can automatically feed the metal powder.

[0029] Example 2: Existing metal powder preparation furnaces require filtration during metal powder preparation, which makes it difficult to avoid filter plate clogging. Therefore, this example uses the following technical solution, such as... Figure 4 and Figure 6 As shown;

[0030] An annular storage plate 9 is fixedly connected to the center of the preparation furnace body 1, and a filter screen 10 is connected to the upper surface of the annular storage plate 9. Fixing plates 11 are fixedly connected to the left and right sides of the center of the preparation furnace body 1 by bolts, and an automatic telescopic rod 12 is fixedly connected to the center of the lower surface of the fixing plate 11. A connecting rod 13 is fixedly connected to the output end of the automatic telescopic rod 12 by bolts. The connecting rod 13 is connected through both the left and right ends of the filter screen 10. A second discharge pipe 14 is fixedly connected to the center of the bottom end of the preparation furnace body 1.

[0031] Metal powder enters the preparation furnace body 1 and falls onto the upper surface of the filter screen 10. After being filtered by the filter screen 10, it is discharged. During filtration, the automatic telescopic rod 12 is activated. The output end of the automatic telescopic rod 12 moves up and down with the connecting rod 13. Since the connecting rod 13 is installed on the filter screen 10, the output end of the automatic telescopic rod 12 can move up and down with the filter screen 10, increasing the filtration efficiency and preventing the filter screen 10 from clogging. The filtered metal powder is discharged from the second discharge pipe 14.

[0032] Example 3: Existing metal powder preparation furnaces require regular cleaning and maintenance and are inconvenient to disassemble. Therefore, this example uses the following technical solution, such as... Figures 1-6 As shown;

[0033] The furnace body 1 is connected to a top cover 2, which is divided into front and rear parts. The front half of the top cover 2 is rotatably connected to the rear half of the top cover 2 by a hinge. A first connecting plate 3 is fixedly connected to the bottom rear side of the top cover 2, and several stabilizing bolts 4 are connected through the first connecting plate 3 at equal angles.

[0034] After the preparation furnace is used, it needs to be cleaned and maintained regularly. At this time, the preparation furnace needs to be disassembled. First, remove the stabilizing bolts 4 on the first connecting plate 3. Then, the top cover 2 and the feeding device 5 can be removed from the preparation furnace body 1. Next, remove the bolts on the fixing plate 11 and the bolts at the output end of the automatic telescopic rod 12. Then, the fixing plate 11 and the automatic telescopic rod 12 can be removed. Finally, take out the filter screen 10, and the preparation furnace can be cleaned and maintained.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
