Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal powder processing technology, specifically a high-efficiency drying device based on metal powder processing. Background Technology
[0002] Metal powder refers to a group of metal particles with a size of less than 1 mm, including single metal powder, alloy powder, and certain refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. When reprocessing metal powder, it is necessary to perform a drying process to achieve the required degree of dryness of the powder.
[0003] Traditional drying methods involve directly placing the metal powder to be dried inside the equipment for high-temperature drying. This method is relatively simple, and if the metal powder has a high moisture content, it will stick together, forming lumps of metal powder, which will affect the drying efficiency and effect. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a high-efficiency drying device based on metal powder processing, which solves the problem that directly putting the metal powder to be dried into the equipment for high-temperature drying is a relatively simple method, and the metal powder will stick together if the moisture content is too high, thus affecting the drying efficiency and effect of the metal powder.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency drying device based on metal powder processing, comprising a drying tank and an extrusion tank, wherein an outer cylinder wall is fixedly installed on the drying tank by bolts, a heating wire is installed between the drying tank and the outer cylinder wall, a discharge pipe is connected to the bottom of the drying tank, and a first motor is fixedly installed on the top of the drying tank, wherein a rotating rod is connected to the output shaft of the first motor;
[0006] Multiple first stirring plates are connected to the rotating rod, and a second stirring plate is connected to one end of the rotating rod. A packing tube is connected to the extrusion tank, and a drain pipe is connected to one side of the extrusion tank. A second motor is fixedly installed on the extrusion tank, and an extrusion roller is connected to the output shaft of the second motor. Blades are connected to the extrusion roller.
[0007] As a further embodiment of this utility model: a connection port is provided on one side of the drying tank, the bottom of the drying tank is a conical design, and a valve body is installed on the discharge pipe.
[0008] As a further embodiment of this utility model: a conical cavity is provided on one side of the extrusion tank, and a connecting pipe is connected to one side of the extrusion tank. The cavity wall of the conical cavity gradually approaches the extrusion roller in the direction close to the connecting pipe, and the distance between the cavity wall of the conical cavity and the blade gradually decreases. The connecting pipe is connected to the connecting port.
[0009] As a further embodiment of this utility model: the extrusion roller is tapered and is rotatably connected inside the extrusion tank; the blades are spirally designed and the spiral spacing is denser closer to the connecting pipe.
[0010] As a further embodiment of this utility model: the first stirring plate is inclinedly disposed on the rotating rod, the rotating rod is rotatably connected to the drying tank, and the second stirring plate is in close contact with the inner wall of the bottom of the drying tank.
[0011] As a further embodiment of this utility model: the heating wire is spirally arranged between the outer wall of the drying tank and the outer cylinder wall, and an exhaust pipe is connected above the drying tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This high-efficiency drying device based on metal powder processing is equipped with a second motor, extrusion rollers, blades, a conical cavity, and heating wires. The operator starts the second motor to drive the extrusion rollers to rotate, and fills the extrusion jar with metal powder through the filling tube. As the extrusion rollers rotate, the spiral blades drive the metal powder to move. With continuous movement, the metal powder gradually adheres to the wall of the conical cavity and is gradually squeezed. This squeezes out the moisture from the metal powder through the extrusion rollers, reducing the moisture content of the metal powder entering the drying jar. Meanwhile, the heating wires gradually heat the drying jar, thereby achieving high-temperature drying and improving the overall drying efficiency.
[0014] 2. This high-efficiency drying device based on metal powder processing is equipped with a first motor, a rotating rod, an exhaust pipe, a first stirring plate, and a second stirring plate. When the heating wire dries the metal powder at high temperature, the first motor is started, causing the rotating rod to rotate and prompting the first stirring plate to stir the metal powder in the drying tank, preventing the metal powder from clumping during drying. At the same time, the second stirring plate will simultaneously stir the metal powder at the bottom of the drying tank to prevent the powder from accumulating and thus improve the drying effect. The gas generated during drying will be discharged from the exhaust pipe. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency drying device based on metal powder processing, including a drying tank 1 and an extrusion tank 2. An outer cylinder wall 3 is fixedly installed on the drying tank 1 by bolts. A heating wire 4 is installed between the drying tank 1 and the outer cylinder wall 3. The heating wire 4 is spirally arranged between the outer wall of the drying tank 1 and the outer cylinder wall 3. An exhaust pipe 19 is connected to the top of the drying tank 1. The heating wire 4 spirally wound on the drying tank 1 is used for heating, thereby drying the metal powder in the drying tank 1 at high temperature. The gas generated during drying is discharged from the exhaust pipe 19, thereby avoiding excessive gas pressure.
[0022] A discharge pipe 5 is connected to the bottom of the drying tank 1, and a connection port 15 is opened on one side of the drying tank 1. The bottom of the drying tank 1 is conical, and a valve body 16 is installed on the discharge pipe 5. Through the conical bottom of the drying tank 1, the metal powder in the drying tank 1 can be easily discharged.
[0023] A first motor 6 is fixedly installed above the drying tank 1. The output shaft of the first motor 6 is connected to a rotating rod 7. Multiple first stirring plates 8 are connected to the rotating rod 7. A second stirring plate 9 is connected to one end of the rotating rod 7. The first stirring plates 8 are inclinedly arranged on the rotating rod 7. The rotating rod 7 is rotatably connected to the drying tank 1. The second stirring plate 9 is in close contact with the inner wall of the bottom of the drying tank 1. By rotating the rotating rod 7, the first stirring plates 8 and the second stirring plates 9 can work together to stir the metal powder in the drying tank 1, ensuring that the powder flows loosely and avoids clumping.
[0024] A packing tube 10 is connected to the extrusion tank 2, and a drain pipe 11 is connected to one side of the extrusion tank 2. A conical cavity 17 is provided on one side inside the extrusion tank 2, and a connecting pipe 18 is connected to one side of the extrusion tank 2. The cavity wall of the conical cavity 17 gradually approaches the extrusion roller 13 in the direction close to the connecting pipe 18, and the distance between the cavity wall of the conical cavity 17 and the blade 14 gradually decreases. The connecting pipe 18 is connected to the connecting port 15. Through the design of the gradually decreasing distance between the cavity wall of the conical cavity 17 and the blade 14, the metal powder can easily enter the depth of the conical cavity 17 when the extrusion roller 13 rotates and is gradually squeezed, thereby squeezing out the moisture to improve the subsequent drying efficiency.
[0025] A second motor 12 is fixedly installed on the extrusion tank 2. The output shaft of the second motor 12 is connected to an extrusion roller 13. Blades 14 are connected to the extrusion roller 13. The extrusion roller 13 is tapered and rotatably connected inside the extrusion tank 2. The blades 14 are spirally designed and the spiral spacing is denser closer to the connecting pipe 18. The spiral blades 14 can transport metal powder when the extrusion roller 13 rotates and gradually compress the metal powder, thereby reducing the moisture content in the powder before high-temperature drying.
[0026] The working principle of this utility model is as follows:
[0027] The second motor 12 drives the extrusion roller 13 to rotate, and the metal powder is filled into the extrusion tank 2 through the filling tube 10. As the extrusion roller 13 rotates, the spiral blades 14 drive the metal powder to move. The continuously moving metal powder gradually adheres to the wall of the conical cavity 17 and is gradually squeezed. Thus, the extrusion roller 13 squeezes out the moisture in the metal powder, reducing the moisture content of the metal powder entering the drying tank 1. The heating wire 4 gradually heats the drying tank 1 to dry the metal powder entering the drying tank 1 at high temperature. At the same time, the first motor 6 drives the rotating rod 7 to rotate, causing the first stirring plate 8 to stir the metal powder in the drying tank 1 to prevent the metal powder from clumping during drying. Meanwhile, the second stirring plate 9 simultaneously stirs the metal powder at the bottom of the drying tank 1 to prevent the powder from accumulating.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
