Description

Technical Field

[0001] This utility model relates to the field of metal powder drying technology, specifically to a powder metallurgy drying device. Background Technology

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metal powder) as raw materials, and manufactures metal materials, composite materials and various types of products through forming and sintering. Metal powder is usually produced by crushing and grinding. Since powder is prone to moisture if stored for too long, it is dried using a drying device before use. Most drying devices are drying ovens with a dryer inside, which can dry the powder.

[0003] However, most existing powder metallurgy drying equipment on the market requires emptying the internally stored powder when drying large quantities of powder, and then collecting it again after drying. This method is troublesome to operate, and the powder is prone to scattering during the emptying and collection process, which affects the indoor environment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a powder metallurgy drying device that does not require pouring and collecting, and can be directly inserted into the storage cylinder for drying operation, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a powder metallurgy drying device, including a storage cylinder, a cylinder cover, a bottom plate, and a heating rod. The storage cylinder is placed on the bottom plate, and the cylinder cover is threaded to the open end of the storage cylinder. A through hole is provided in the center of the cylinder cover. One end of the heating rod extends through the through hole into the storage cylinder. Multiple grooves are provided on the outer ring surface of the heating rod, and stirring rods are installed in each groove. A support frame is installed on the bottom plate, and a cylinder is installed on the support frame. A motor is installed on the piston rod of the cylinder, and the rotating shaft of the motor is fixedly connected to the heating rod through a connecting flange.

[0006] As a preferred technical solution, the surface of the cylinder cover is provided with grooves on both sides of the through hole, a slider is slidably installed in the groove, a baffle is installed on the outer end of the slider to cover the through hole, a compression spring is installed between the slider and the groove, and the cross-section of the slider and the groove are both set in a trapezoidal structure.

[0007] As a preferred technical solution, mounting grooves are provided on both sides of the groove, and a spring is installed in each mounting groove. A shaft is installed in the inner ring of each spring, and the other end of the shaft is fixedly connected to the stirring rod.

[0008] As a preferred technical solution, a collector ring is installed on the exposed end of the heating rod, the wires of the heating rod are fixedly connected to the movable end of the collector ring, a power cord is installed on the fixed end of the collector ring, and a temperature controller is installed on the power cord.

[0009] As a preferred technical solution, a vibrator is embedded in the center of the base plate, and the vibrating end of the vibrator is in contact with the bottom surface of the storage cylinder.

[0010] As a preferred technical solution, the outer surface of the stirring rod is designed with an arc shape, and the degree of arc of the outer arc structure of the stirring rod matches the degree of arc of the outer wall of the heating rod.

[0011] As a preferred technical solution, the stirring rods are all made of metal.

[0012] The beneficial effects of this utility model are: This utility model has a simple structure.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a powder metallurgy drying device of this utility model includes a storage cylinder 1, a cylinder cover 4, a base plate 11, and a heating rod 5. The storage cylinder 1 is placed on the base plate 11. The cylinder cover 4 is threaded to the open end of the storage cylinder 1. A through hole is provided at the center of the cylinder cover 4. One end of the heating rod 5 extends into the storage cylinder 1 through the through hole. A plurality of grooves 16 are provided on the outer ring surface of the heating rod 5. A stirring rod 14 is installed in each of the grooves 16. A support frame 2 is installed on the base plate 11. A cylinder 3 is installed on the support frame 2. A motor 8 is installed on the piston rod of the cylinder 3. The rotating shaft of the motor 8 is fixedly connected to the heating rod 5 through a connecting flange.

[0023] In this embodiment, the surface of the cylinder cover 4 is provided with sliding grooves on both sides of the through hole. A slider 12 is slidably installed in the sliding groove. A baffle 9 covering the through hole is installed on one side of the slider 12. A compression spring 10 is installed between the slider 12 and the sliding groove. The cross sections of the slider 12 and the sliding groove are both set in a trapezoidal structure.

[0024] This allows the baffle to move back and forth along the groove, preventing it from detaching from the cylinder cover.

[0025] In this embodiment, mounting grooves are provided on both sides of the groove 16, and springs 17 are installed in the mounting grooves. A shaft 18 is installed in the inner ring of the spring 17, and the other end of the shaft 18 is fixedly connected to the stirring rod 14.

[0026] In this embodiment, a collector ring 6 is installed on the exposed end of the heating rod 5. The wires of the heating rod 5 are fixedly connected to the movable end of the collector ring 6. A power line 7 is installed on the fixed end of the collector ring 6. A thermostat is installed on the power line 7. When the heating rod is driven by the motor, the wires on the heating rod can rotate on the movable end, avoiding the twisting of the wires. The temperature of the heating rod during heating can be controlled by the thermostat.

[0027] In this embodiment, a vibrator 15 is embedded in the center of the base plate 11, and the vibrating end of the vibrator 15 is in contact with the bottom surface of the storage cylinder 1.

[0028] During the stirring process, the vibrator can be activated, and the heat generated by the vibrator can act on the storage cylinder, causing the powder inside to vibrate, thereby increasing the drying efficiency.

[0029] In this embodiment, the outer surface of the stirring rod 14 is all arc-shaped. The degree of arc of the outer arc structure of the stirring rod 14 matches the degree of arc of the outer wall of the heating rod 5. After the stirring rod moves inward, the stirring rod can enter the groove and make the outer surface of the stirring rod flush with the outer wall of the heating rod, thus avoiding unevenness that would affect the heating rod from moving out of the through hole.

[0030] In this embodiment, the stirring rods 14 are all made of metal, which allows the stirring rods to quickly absorb the heat generated by the heating rods, enabling the stirring rods to dry the powder inside while stirring.

[0031] In use, place the storage cylinder containing metal powder on the base plate and push the baffle outward. After the baffle moves outward along the slide groove, the through hole will open. At this time, squeeze the stirring rod inward to make it enter the groove, and start the cylinder to make the piston rod of the cylinder extend downward to push the heating rod through the through hole and insert it into the storage cylinder to contact the powder inside. After the stirring rod is inserted into place, the stirring rod can be automatically opened outward by the twisting of the spring, which increases the contact area with the powder.

[0032] The heat generated by the heating rod can be directly transferred to the stirring rod. After the motor is started, it can drive the heating rod and the stirring rod to rotate, so that the drying operation can be carried out while heating. The water vapor generated during the heating process can pass through the small gap between the heating rod and the through hole.

[0033] After drying, the piston rod of the cylinder is retracted again, and the heating rod is moved upward from the through hole. There is no need to pour out the powder inside or collect it later. After the heating rod is no longer blocking the flow, the return of the compression spring will move the baffle back to the outside of the through hole, thereby blocking the through hole.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
