Technical Field
[0001] The utility model relates to a drying device, in particular to a drying device for metal powder processing. Background Art
[0002] The preparation of metal powder is a key step in powder metallurgy process. If the water atomization method or gas atomization method is used to prepare metal powder, the metal powder obtained after processing will contain certain moisture or other volatile substances. If these impurities are not removed, they will affect the purity, stability and use effect of the powder. Generally speaking, these impurities can be effectively removed by drying to improve the quality of the powder, so the metal powder obtained after processing needs to be dried.
[0003] The existing metal powder drying method usually directly pours the metal powder into a drying barrel for heating and drying. However, since the metal powder may contain moisture and other volatile substances, these components are likely to cause the metal powder particles to stick to each other during the heating process, thus significantly reducing the drying efficiency of the drying barrel. Content of the Utility Model
[0004] In order to overcome the drawback that when the existing drying barrel dries metal powder, the metal powder in the drying barrel is prone to stick together, reducing the drying efficiency of the drying barrel, the purpose of the utility model is to provide a drying device for metal powder processing.

[0007] Further, a wedge block is arranged at the right end of the fixing rod. The inclined surface of the wedge block is inclined to the right, gradually inclining from the top end to the bottom end. The wedge block can pass through the square hole on the barrel cover.
[0008] Further, it also includes a baffle, a heat insulation handle and a limiting rod. A round hole is arranged at the left side of the bottom end of the drying barrel. The baffle is slidably connected to the lower part of the left end of the drying barrel. The baffle can completely cover the round hole. The left end of the baffle is connected with a heat insulation handle. The limiting rod is arranged at the left side of the bottom end of the drying barrel, and a convex block is arranged at the left side of the top end of the limiting rod.
[0009] Furthermore, a heat insulation pad is sleeved on the outer side of the heat insulation handle.
[0010] Furthermore, it further includes a locking rod. Small holes are symmetrically arranged on the front and rear sides of the baffle. Locking rods are symmetrically arranged on the front and rear sides of the lower part of the left end of the drying barrel, and the locking rods can pass through the small holes.

Detailed implementation manner
[0021] The present utility model will be specifically described below in conjunction with the attached drawings.
[0022] A drying device for metal powder processing, as Figure 1 and Figure 6 shown, includes a support 1, a drying barrel 2, a barrel cover 3, a mounting rack 8, a motor 9 and a stirrer 10. The drying barrel 2 is provided on the support 1, and the barrel cover 3 is slidably connected to the support 1. The barrel cover 3 can slide up and down on the support 1. The top end of the drying barrel 2 completely coincides with the bottom end of the barrel cover 3. Square holes are symmetrically arranged at the front and rear ends of the barrel cover 3. Mounting racks 8 are symmetrically arranged on the front and rear sides of the top end of the barrel cover 3. A motor 9 is connected between the two mounting racks 8. A stirrer 10 is connected to the output shaft of the motor 9. By driving the stirrer 10 with the motor 9, the metal powder in the drying barrel 2 can be stirred.
[0023] As Figure 2 and Figure 5 shown, it further includes a fixing rod 11 and a first elastic member 12. The fixing rod 11 is slidably connected to the upper part of the support 1. When the barrel cover 3 moves to the upper part of the support 1, the fixing rod 11 can be used to clamp the barrel cover 3, so that the barrel cover 3 is fixed to the upper part of the support 1. A first elastic member 12 is connected between the fixing rod 11 and the support 1. A wedge block is provided at the right end of the fixing rod 11. The inclined surface of the wedge block is inclined to the right and gradually inclines from the top end to the bottom end. The wedge block can pass through the square hole on the barrel cover 3 to clamp the barrel cover 3.
[0024] As Figure 1 and Figure 2 shown, it further includes a baffle 4, a heat insulation handle 5 and a limiting rod 7. A circular hole is provided on the left side of the bottom end of the drying barrel 2. The baffle 4 is slidably connected to the lower part of the left end of the drying barrel 2. The baffle 4 can completely cover the circular hole. The left end of the baffle 4 is connected with a heat insulation handle 5. A limiting rod 7 is provided on the left side of the bottom end of the drying barrel 2. A convex block is provided at the top left end of the limiting rod 7. The convex block on the limiting rod 7 can effectively limit the leftward movement of the baffle 4. A heat insulation pad is sleeved on the outside of the heat insulation handle 5. When the human hand drags the heat insulation handle 5, the heat insulation pad can prevent the human hand from being scalded.
[0025] As Figure 6 shown, it further includes a locking rod 6. Small holes are symmetrically arranged on the front and rear sides of the baffle 4. Locking rods 6 are symmetrically arranged on the front and rear sides of the lower part of the left end of the drying barrel 2. The locking rods 6 can pass through the small holes to fix the baffle 4.
[0026] As Figure 4 shown, it further includes a collection mechanism, which includes a cam 13, a limit block 14, a push rod 15, a placement seat 16, a collection box 17 and a second elastic member 18. A cam 13 is provided on the output shaft of the motor 9. The cam 13 is located at the top of the barrel cover 3. A limit block 14 is provided on the right side at the top of the barrel cover 3. A push rod 15 is slidably connected to the limit block 14. When the motor 9 drives the cam 13 to rotate, the distal end of the cam 13 will squeeze the push rod 15, pushing the push rod 15 to move to the right. A placement seat 16 is slidably connected to the bracket 1. A second elastic member 18 is provided between the front and rear ends of the placement seat 16 and the bracket 1. A collection box 17 is provided on the placement seat 16. The collection box 17 is located below the drying barrel 2. The collection box 17 can collect the dried metal powder. The upper part of the placement seat 16 is an L-shaped rod, and the upper end of the L-shaped rod is in contact with the push rod 15. The lower part of the placement seat 16 is a circular frame, and the collection box 17 is located within the circular frame.
[0027] When people use this device, they first need to lift the bucket cover 3 to put metal powder into the drying bucket 2. Lift the bucket cover 3 by hand, and the bucket cover 3 drives the stirrer 10 to move upward. The upper end of the placement seat 16 separates from the push rod 15. When the bucket cover 3 reaches the fixed rod 11, the bucket cover 3 squeezes the inclined surface of the wedge block on the fixed rod 11, and the fixed rod 11 slides to the left. The first elastic member 12 changes from the initial state to the compressed state. After the wedge block on the fixed rod 11 faces the square hole of the bucket cover 3, the first elastic member 12 resets, and the wedge block passes through the square hole on the bucket cover 3, and the fixed rod 11 locks the bucket cover 3. Pour metal powder into the drying bucket 2. Pull the fixed rod 11, and the fixed rod 11 moves to the right. The first elastic member 12 is compressed. The bucket cover 3 drives the stirrer 10 to move downward until it contacts the top end of the drying bucket 2. At this time, the upper end of the placement seat 16 contacts the push rod 15 again. Release the fixed rod 11, and the first elastic member 12 resets, driving the fixed rod 11 back to the initial position. Start the motor 9 and the heating function of the drying bucket 2. The motor 9 drives the stirrer 10 and the cam 13 to rotate together. The stirrer 10 rotates to stir the metal powder in the drying bucket 2, and the drying bucket 2 is heated to remove the moisture in the metal powder. When the distal end of the cam 13 squeezes the push rod 15, the placement seat 16 drives the collection frame 17 to move to the right together. The second elastic member 18 changes from the initial state to the compressed state. When the distal end of the cam 13 disengages from the push rod 15, the second elastic member 18 resets, driving the placement seat 16 to drive the collection frame 17 to move to the left together. The rotation of the cam 13 realizes the left and right shaking of the collection frame 17, which can prevent the metal powder falling into the collection frame 17 from accumulating in one place. After the metal powder is dried, remove the locking rod 6, pull the heat insulation handle 5 to the left, and pull out the baffle 4 so that the left end of the baffle 4 contacts the convex block on the limit rod 7. At this time, the stirrer 10 continuously stirs the metal powder and pushes the metal powder into the round hole at the bottom end of the drying bucket 2. Finally, the metal powder falls into the collection frame 17. The collection frame 17 moves left and right to ensure that the metal powder can be evenly distributed in the collection frame 17. After all the metal powder falls into the collection frame 17, turn off the motor 9 and the heating function of the drying bucket 2. The cam 13 stops rotating accordingly, and the collection frame 17 no longer moves left and right. Push the heat insulation handle 5 to the right, and the baffle 4 moves to the right to cover the round hole at the bottom end of the drying bucket 2. Insert the locking rod 6 back into the small hole on the baffle 4, and remove the collection frame 17 to complete the processing of the metal powder.
