Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, and more specifically, to a drum mixer. Background Technology
[0002] Magnetic foreign matter is a common foreign object found in battery raw materials. It can be introduced from environmental factors, equipment, and raw material sources, and its presence significantly impacts the functionality of battery raw materials. Therefore, detecting the content of magnetic foreign matter in battery raw materials is crucial for assessing their quality.
[0003] Currently, the detection of magnetic foreign matter typically involves placing a magnetic rod and the sample inside a drum, which is then rotated by a motor. The rotation of the drum causes the magnetic rod and sample to rotate as well, allowing them to contact each other for a certain period before removal. However, because the magnetic rod and sample can only rotate with the drum, their trajectories are identical. This means the magnetic rod cannot make sufficient contact with the sample, and magnetic foreign matter in the sample cannot be completely adsorbed by the magnetic rod. Consequently, the analytical results may not accurately reflect the content of magnetic foreign matter in the tested product. Utility Model Content
[0004] The purpose of this invention is to provide a drum mixer that allows the magnetic rod to fully contact the sample, thus ensuring the accuracy of the detection of magnetic foreign matter content.
[0005] This utility model is achieved through the following technical solution:
[0006] A drum-type mixer includes a frame, a drum assembly, and a drive device. The drum assembly is mounted on the frame. The inner cavity of the drum assembly is provided with a rotatable magnetic rod assembly. The drive device includes a first drive mechanism and a second drive mechanism that control the drum assembly and the magnetic rod assembly to rotate in opposite directions. The magnetic rod assembly includes at least three magnetic rods arranged parallel to each other along the drum axis. The drum assembly has a compartmentalized structure, which is composed of a plurality of partitions evenly distributed along the circumference. A mixing compartment is formed between adjacent partitions, and the ends of the magnetic rods extend into each mixing compartment.
[0007] Furthermore, the inner cavity of the roller assembly is rotatably provided with a mounting base, and the magnetic rod is detachably mounted on the mounting base via a quick-release connector.
[0008] Furthermore, the quick-release connector is provided with a limiting groove and a locking protrusion, and the mounting base is provided with a limiting hole. One end of the locking protrusion is slidably installed in the limiting groove, and the other end of the locking protrusion is inserted into the limiting hole.
[0009] Furthermore, the magnetic rod is threadedly connected to the quick-release connector.
[0010] Furthermore, the second drive mechanism includes a second motor, the output end of which is connected to the mounting base.
[0011] Furthermore, the outer wall of the roller assembly is provided with an annular rack, the first drive mechanism includes a first motor and a gear, the output end of the first motor is connected to a rotating shaft, the gear is mounted on the rotating shaft, and the gear meshes with the annular rack.
[0012] Furthermore, a slide rail is fixedly installed on the top of the frame, and a ring is slidably connected inside the slide rail, the ring being fixedly sleeved on the outer wall of the roller assembly.
[0013] Furthermore, the partition plate is provided with a plurality of turbulence holes, the diameter of which gradually increases along the rotation direction of the drum.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0015] In this invention, the counter-rotating differential speed of the magnetic rod assembly and the drum assembly allows for more thorough contact between the magnetic rod and the sample, improving the adsorption effect of magnetic foreign matter on the magnetic rod and ensuring the accuracy of magnetic foreign matter content detection. The compartmentalized structure generates strong shearing forces within the mixing chamber, causing intense shearing and stirring of the sample within the drum. This shearing force increases the relative motion between samples, promoting contact between the sample and the magnetic rod, improving mixing efficiency, and simultaneously reducing dead zones, preventing insufficient sample flow from affecting the contact effect with the magnetic rod.

[0027] Example 1
[0028] like Figures 1-4 As shown, this embodiment provides a drum-type mixer, including a frame 1, a drum assembly 2, and a drive device. The drum assembly 2 is mounted on the frame 1. The inner cavity of the drum assembly 2 is provided with a rotatable magnetic rod assembly. The drive device includes a first drive mechanism and a second drive mechanism that control the drum assembly 2 and the magnetic rod assembly to rotate in opposite directions, respectively. The magnetic rod assembly includes at least three magnetic rods 11 arranged parallel to each other along the drum axis. The drum assembly 2 is provided with a compartment structure, which is composed of a plurality of partitions 7 evenly distributed along the circumference. A mixing compartment 14 is formed between adjacent partitions 7, and the ends of the magnetic rods 11 extend into each mixing compartment 14.
[0029] By rotating the magnetic rod assembly and the drum assembly 2 in opposite directions at different speeds, the magnetic rod 11 can make more thorough contact with the sample, improving the adsorption effect of magnetic foreign matter on the magnetic rod 11 and ensuring the accuracy of magnetic foreign matter content detection. The compartmentalized structure generates strong shearing force within the mixing chamber 14, causing the sample to undergo intense shearing and stirring within the drum. This shearing force increases the relative motion between samples, promoting contact between the sample and the magnetic rod 11, improving mixing efficiency, and also reducing dead zones, preventing insufficient sample flow from affecting the contact effect with the magnetic rod 11.
[0030] In this specific embodiment, the inner cavity of the roller assembly 2 is rotatably provided with a mounting base 13, and the magnetic rod 11 is detachably mounted on the mounting base 13 via a quick-release connector 10. The detachable design of the magnetic rod 11 facilitates cleaning and replacement, and is suitable for different experimental needs.
[0031] In a specific embodiment of this invention, the quick-release connector 10 is provided with a limiting groove 101 and a locking protrusion 102, and the mounting base 13 is provided with a limiting hole. One end of the locking protrusion 102 is slidably installed in the limiting groove 101, and the other end of the locking protrusion 102 is inserted into the limiting hole. Preferably, the quick-release connector 10 is provided with a bolt, which is used to control the movement of the locking protrusion 102. There are two locking protrusions 102, and the bolt is a double-ended bolt 103, which controls the two locking protrusions 102 to move closer or further apart.
[0032] In this specific embodiment, the magnetic rod 11 is threadedly connected to the quick-release connector 10. The detachable design of the magnetic rod 11 and the quick-release connector 10 facilitates the replacement of the magnetic rod 11, ensuring the magnetic attraction effect of the magnetic rod 11.
[0033] In a specific embodiment of this invention, the second driving mechanism includes a second motor 9, the output end of which is connected to the mounting base 13. The second motor 9 drives the mounting base 13 to rotate, thereby driving the magnetic rod 11 to rotate, achieving rotation of the magnetic rod 11 within the roller assembly 2, allowing the magnetic rod 11 to better contact the sample. Preferably, the roller assembly 2 includes a cylinder 22 and a cylinder cover 21, which are fixedly connected by a connecting buckle. The connecting buckle is a fastener that can achieve connection and fixation in the prior art. The cylinder cover 21 has a cavity, and a connecting rod 12 is provided at the bottom of the cylinder cover 21. The mounting base 13 is located below the connecting rod 12. The second motor 9 is fixedly installed in the cavity, and the output end of the second motor 9 passes through the cylinder cover 21 and the connecting rod 12 and is fixedly connected to the mounting base 13. The second motor 9 drives the mounting base 13 to rotate, thereby achieving rotation of the magnetic rod 11.
[0034] In a specific embodiment of this invention, the outer wall of the roller assembly 2 is provided with an annular rack 4. The first driving mechanism includes a first motor 5 and a gear 6. The output end of the first motor 6 is connected to a rotating shaft, and the gear 6 is mounted on the rotating shaft. The gear 6 meshes with the annular rack 4. The first motor 5 is mounted on the frame 1. The first motor 5 drives the gear 6 to rotate, and the gear 6 drives the annular rack 4 to rotate, thereby driving the roller assembly 2 to rotate and realizing the rapid rotation of the roller assembly 2.
[0035] In this specific embodiment, a slide rail 3 is fixedly installed on the top of the frame 1, and a ring is slidably connected inside the slide rail 3. The ring is fixedly sleeved on the outer wall of the roller assembly 2. The cooperation between the slide rail 3 and the ring can improve the stability of the roller assembly 2 during rotation.
[0036] In a specific embodiment of this invention, the partition 7 is provided with a plurality of turbulence holes 8, the diameter of which gradually increases along the rotation direction of the drum. The turbulence holes 8 allow the samples in each mixing chamber 14 to flow to each other, promoting contact between the magnetic rod 11 and the sample. At the same time, the turbulence holes 11 can also cause the sample to generate eddy current motion, further improving the fluidity of the sample.
[0037] The working principle of a drum mixer is as follows: Quick-release connector 10 is connected to mounting base 13, and magnetic rod 11 is connected to quick-release connector 10. The cylinder cover 21 is then placed on the cylinder body 22. In use, the first motor 5 is started, driving gear 6 to rotate. Gear 6 drives the ring rack 4 to rotate, thus causing the drum assembly 2 to rotate within the slide rail 3, achieving synchronous rotation of the cylinder body 22 and cylinder cover 21. The second motor 9 is then started, driving mounting base 13 to rotate. Mounting base 13 drives quick-release connector 10 to rotate, thus causing magnetic rod 11 on quick-release connector 10 to rotate, allowing magnetic rod 11 to contact the sample and adsorb magnetic foreign objects.
[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
