Description

Technical Field

[0001] This utility model relates to the field of magnetic powder stirring technology, and more specifically, to a high-efficiency magnetic powder stirring device. Background Technology

[0002] Magnetic powder, as an important functional material, has wide applications in various fields such as magnetic material preparation, magnetic recording materials, magnetic fluids, biomedicine, and environmental protection. The dispersion state and uniformity of magnetic powder in liquids have a crucial impact on the performance of the final product.

[0003] For example, the magnetic suspension stirring device for magnetic particle inspection disclosed in application publication number CN103432946 A includes a cylinder, a blade-type stirring device installed on the top of the cylinder, a liquid outlet at the bottom of the cylinder, a valve plate installed at the liquid outlet, a set of air guide pipes installed inside the cylinder, the air guide pipes being evenly arranged longitudinally downward along the inner wall of the cylinder, the air guide pipes being connected to a main air supply pipe, the main air supply pipe being connected to an air compressor, and the stirring device including a stirring shaft, the stirring shaft being connected to a first drive motor, and downward spiral blades being installed on the stirring shaft.

[0004] In the above, the first motor drives the spiral blades to rotate. During the rotation of the spiral blades, the spiral blades themselves do not rotate. For magnetic powders with high viscosity or large particles, this stirring method has poor stirring effect, resulting in uneven stirring of the magnetic powder. Since the spiral blades can only stir the magnetic powder once, the stirring speed of the magnetic powder is slow. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency magnetic powder stirring device that can achieve more uniform stirring and improve stirring speed.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency magnetic powder stirring device includes a cylinder and a frame, with the frame positioned on one side of the cylinder. The cylinder has a cavity for holding magnetic powder.

[0008] The frame is equipped with a stirring assembly, which is placed inside the receiving chamber.

[0009] The mixing assembly includes a cylinder connected to the frame, a sliding plate slidably connected to the frame, a first motor, and a mixing rod.

[0010] The sliding plate is positioned between the cylinder and the first motor, and the first motor is positioned between the sliding plate and the stirring rod. The output end of the cylinder is connected to the top surface of the sliding plate.

[0011] The first motor is placed on the bottom surface of the sliding plate, and its output end is connected to one end of the stirring rod.

[0012] The stirring rod is equipped with a swing shaft, which is located outside the stirring rod and is perpendicular to the stirring rod. A second motor is installed inside the stirring rod, and the output end of the second motor passes through the stirring rod and is connected to one end of the swing shaft. Several blades are installed on the swing shaft, which is surrounded by the outer wall of the swing shaft.

[0013] The present invention is further configured such that: the stirring rod is provided with a plurality of first guide rods surrounding the outer wall of the stirring rod, the first guide rods are positioned above the swing shaft, and one end of the first guide rods is fixedly connected to the outer wall of the stirring rod.

[0014] The present invention is further configured such that: a plurality of second guide rods are provided on the first guide rod, the second guide rods are placed below the first stirring rod, and the second guide rods are perpendicularly connected to the first guide rod.

[0015] The present invention is further configured such that: a sliding groove is provided on the frame, and a slider is provided on one side of the sliding plate, the slider being placed in the sliding groove and slidably connected to the sliding groove.

[0016] The present invention is further configured such that a storage slot for placing a second motor is provided on one side of the stirring rod.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0018] The magnetic powder is placed in the receiving chamber. First, the cylinder is activated to place all the stirring components in the receiving chamber. The cylinder then stops operating, and the first motor is activated. The stirring rod stirs the magnetic powder for the first time. As the stirring rod rotates, the first and second guide rods stir the magnetic powder a second time. The second motor is then activated, driving the oscillating shaft to rotate. The oscillating shaft stirs the magnetic powder a third time. Through these three stirring processes, the stirring speed is increased. During stirring, the blades on the oscillating shaft further cut the magnetic powder, resulting in more uniform stirring. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 As shown, the high-efficiency magnetic powder stirring device includes a cylinder 1 and a frame 2. The cylinder 1 has a receiving chamber, into which magnetic powder can be placed. The frame 2 is equipped with a stirring assembly.

[0024] The stirring assembly includes a cylinder 3 connected to the frame 2, a sliding plate 4 slidably connected to the frame 2, a first motor 5, and a stirring rod 6. The sliding plate 4 is placed between the cylinder 3 and the first motor 5, and the first motor 5 is placed between the sliding plate 4 and the stirring rod 6. The output end of the cylinder 3 is connected to the top surface of the sliding plate 4, and the first motor 5 is placed on the bottom surface of the sliding plate 4, with its output end connected to one end of the stirring rod 6.

[0025] The cylinder 3 is operated, which moves the sliding plate 4 up and down until the stirring rod 6 is completely placed in the receiving chamber. The first motor 5 is then operated, which drives the stirring rod 6 to rotate, causing the magnetic powder in the receiving chamber to be stirred. The frame 2 is provided with a sliding groove 11, and a slider 12 is installed on one side of the sliding plate 4. During the movement of the sliding plate 4, the slider 12 slides in the sliding groove 11, which plays a buffering role for the sliding block.

[0026] Two swing shafts 7 are installed on the stirring rod 6, with the two swing shafts 7 located on both sides of the stirring rod 6. Both swing shafts 7 are placed outside the stirring rod 6 and are perpendicular to the stirring rod 6. Two storage slots are opened on the stirring rod 6, and a second motor 8 is installed in each of the two storage slots. The output end of the second motor 8 is connected to one end of the swing shaft 7. When the second motor 8 is running, the second motor 8 drives the swing shaft 7 to rotate. While the stirring rod 6 is rotating and stirring the magnetic powder, the swing shaft 7 is also stirring the magnetic powder by rotating.

[0027] Because the swing shaft 7 is equipped with several blades that surround the outer wall of the swing shaft 7, when the swing shaft 7 rotates, the blades can cut magnetic powder over a large area. The stirring rod 6 is also equipped with four first guide rods 9 that surround the outer wall of the stirring rod 6. The first guide rods 9 are positioned above the swing shaft 7, and one end of the first guide rod 9 is integrally formed with the outer wall of the stirring rod 6.

[0028] The first guide rod 9 is provided with three second guide rods 10 arranged separately. The second guide rods 10 are placed below the first stirring rod 6 and are fixed perpendicularly to the first guide rod 9. When the first motor 5 drives the stirring rod 6 to rotate, the first guide rod 9 and the second guide rod 10 rotate simultaneously to stir the magnetic powder.

[0029] Working principle: The magnetic powder is placed in the receiving chamber. First, the cylinder 3 is run to place all the stirring components in the receiving chamber. The cylinder 3 stops running, and the first motor 5 is run. The stirring rod 6 stirs the magnetic powder for the first time. As the stirring rod 6 rotates, the first guide rod 9 and the second guide rod 10 stir the magnetic powder for the second time. The second motor 8 is run, and the second motor 8 drives the swing shaft 7 to rotate. The swing shaft 7 stirs the magnetic powder for the third time. Through three stirrings, the stirring speed is increased. During stirring, the blades on the swing shaft 7 further cut the magnetic powder, thus making the stirring more uniform.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
