Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for powder production. Background Technology

[0002] Powder typically refers to an aggregate of discrete particles with a size of less than 1 mm. Powders of different materials need to be filtered through a filtration and screening device during production and processing.

[0003] However, most existing powder production filtration devices use screen vibration for filtration, which makes it easy for powder to accumulate on the upper part of the screen and results in low filtration efficiency. Therefore, a new powder production filtration device is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for powder production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for powder production, comprising a base, a plurality of springs connected to the base, a common cylinder connected to the top of the plurality of springs, a filter screen disposed inside the cylinder, a motor disposed inside the base, a drive gear connected to the motor, an inclined column disposed on the drive gear, a connecting column disposed at the bottom end of the cylinder, the connecting column contacting the inclined surface of the inclined column, an internal gear ring groove being formed on the base, a driven gear meshing between the internal gear ring groove and the drive gear, and a counterweight disposed on the driven gear.

[0006] Preferably, a plurality of guide posts are connected to the bottom end of the cylinder, each guide post is arranged inside a spring, and the plurality of guide posts are slidably connected to the top end of the base.

[0007] Preferably, a first discharge port is connected to one side of the cylinder, which communicates with the upper part of the filter screen, and a second discharge port is connected to the other side of the cylinder, which communicates with the bottom of the cylinder.

[0008] Preferably, a ball bearing is rotatably connected to the bottom end of the connecting column, and the ball bearing is in contact with the inclined surface of the inclined column.

[0009] Preferably, the base has a first annular groove, and a first positioning shaft is connected to the bottom end of the driven gear. The first positioning shaft is T-shaped and is movably connected in the first annular groove.

[0010] Preferably, a square shaft is slidably connected to the top of the counterweight, and the square shaft is movably connected to the bottom of the cylinder.

[0011] Preferably, a second annular groove is provided at the bottom end of the cylinder, and a second positioning shaft is connected to the top end of the square shaft. The second positioning shaft is T-shaped and is movably connected within the second annular groove.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a motor drives the active gear to rotate, causing the inclined column to rotate in a circular motion. Through the cooperation of the connecting column, the cylinder, connected by a spring, continuously generates a vertical vibration effect, thereby improving the filtration effect of powder on the filter screen. At the same time, the active gear meshes with the driven gear, and through the meshing of the internal gear ring groove, the driven gear rotates while rotating in a circular motion, thereby driving the counterweight to rotate in a circular direction. This causes the center of gravity of the entire device to shift in a circular direction, which in turn causes the cylinder to generate centrifugal force in a circular direction. This gradually spreads the powder accumulated on the filter screen to all sides, further improving the filtration effect and preventing local accumulation from affecting the filtration progress and efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4A powder production filtration device includes a base 1, a plurality of springs 2 connected to the base 1, a common cylinder 3 connected to the top of the plurality of springs 2, a filter screen 4 disposed inside the cylinder 3, a motor 5 disposed inside the base 1, a drive gear 6 connected to the motor 5, an inclined column 7 disposed on the drive gear 6, a connecting column 8 disposed at the bottom end of the cylinder 3, the connecting column 8 contacting the inclined surface of the inclined column 7, an internal gear ring groove 9 formed on the base 1, a driven gear 10 meshing between the internal gear ring groove 9 and the drive gear 6, and a counterweight 11 disposed on the driven gear 10.

[0021] The motor 5 drives the drive gear 6 to rotate, causing the inclined column 7 to generate a circular motion. Through the cooperation of the connecting column 8, the cylinder 3, connected by the spring 2, always generates a vertical vibration effect, thereby improving the filtration effect of powder on the filter screen 4. At the same time, the drive gear 6 meshes with the driven gear 10. Through the meshing of the internal gear ring groove 9, the driven gear 10 rotates while performing a circular motion, thereby driving the counterweight 11 to rotate in a circular direction. This causes the center of gravity of the entire device to shift in a circular direction, which in turn causes the cylinder 3 to generate a centrifugal force in a circular direction. This gradually spreads the powder accumulated on the filter screen 4 to all sides, further improving the filtration effect and preventing local accumulation from affecting the filtration progress and efficiency.

[0022] Specifically, in this embodiment, a number of guide posts 12 are connected to the bottom end of the cylinder 3. Each guide post 12 is arranged inside the spring 2. The guide posts 12 are slidably connected to the top end of the base 1 to further ensure the vertical vibration effect of the cylinder 3.

[0023] Specifically, in this embodiment, a first discharge port 13 is connected to one side of the cylinder 3, and the first discharge port 13 communicates with the upper part of the filter screen 4. A second discharge port 14 is connected to the other side of the cylinder 3, and the second discharge port 14 communicates with the bottom of the cylinder 3, so that the filtered powder can be discharged from the second discharge port 14, and the large particles of impurities screened out can be discharged from the first discharge port 13. The design of different directions can improve the classification effect.

[0024] Specifically, in this embodiment, a ball bearing 15 is rotatably connected to the bottom end of the connecting column 8. The ball bearing 15 contacts the inclined surface of the inclined column 7, thereby improving the smoothness of the fit between the connecting column 8 and the inclined column 7.

[0025] Specifically, in this embodiment, a first annular groove 16 is provided on the base 1, and a first positioning shaft 17 is connected to the bottom end of the driven gear 10. The first positioning shaft 17 is T-shaped and is movably connected in the first annular groove 16, which ensures that the driven gear 10 rotates and revolves while providing positioning for the driven gear 10, thereby improving the stability of the meshing transmission.

[0026] Specifically, in this embodiment, a square shaft 18 is slidably connected to the top of the counterweight 11. The square shaft 18 is movably connected to the bottom of the cylinder 3, which improves the transmission effect of centrifugal force of the cylinder 3, provides room for vertical vibration of the cylinder 3, and allows the counterweight 11 to rotate smoothly.

[0027] Specifically, in this embodiment, a second annular groove 19 is provided at the bottom of the cylinder 3, and a second positioning shaft 20 is connected to the top of the square shaft 18. The second positioning shaft 20 is T-shaped and is movably connected in the second annular groove 19, which improves the connection effect between the square shaft 18 and the cylinder 3, and ensures the rotation and revolution of the square shaft 18 under the drive of the counterweight 11.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
