Description

Technical Field

[0001] This invention relates specifically to the field of particle detection device technology, and more specifically to a multi-stage dispersion and anti-agglomeration particle detection device. Background Technology

[0002] The dispersion state and particle size distribution of particulate materials are core quality control indicators in the production processes of industrial fields such as food processing, pharmaceutical preparations, chemical raw materials, and new energy materials. The accuracy of their detection directly determines product quality and production efficiency. Currently, most particle detection devices in the industry are based on single vibrating sieving or visual inspection, but there are many technical bottlenecks in practical applications, making it difficult to meet the detection requirements of high precision and high adaptability.

[0003] Existing particle detection devices generally suffer from the drawback of relying on a single dispersion method. They depend on only a single vibration source or a simple stirring structure to disperse materials, which cannot effectively break down the van der Waals forces and agglomeration forces between particles. This easily leads to agglomerated particles remaining on the screen surface, resulting in detection data that cannot accurately reflect the state of individual particles and causing product quality control deviations. At the same time, most devices only use a single-layer screen for particle grading, which cannot achieve accurate differentiation of particles of multiple sizes. The detection dimension is limited, making it difficult to adapt to detection scenarios involving multi-specification particulate materials.

[0004] In the detection process, the cameras of traditional devices are mostly fixed in position, and the shooting angle cannot be adjusted according to the particle size and material flow state. This results in many blind spots in the camera shooting, making it difficult to accurately capture the particle dynamics in different areas of the screen and in the fine material discharge pipe, which greatly reduces the detection accuracy.

[0005] In the discharge stage, the traditional device's flow guide structure is poorly designed, causing material to easily accumulate in the discharge channel. This not only affects material flow efficiency but also leads to secondary particle agglomeration, disrupting the continuity of detection. Furthermore, the existing devices mostly feature an integrated frame design, making disassembly and maintenance difficult. If a core detection component or dispersion assembly malfunctions, the entire system must be shut down and disassembled, severely impacting production efficiency and operating costs.

[0033] In this embodiment, the installation platform 12 has a circular groove at its center; the upper surface of the installation platform 12 is fixedly connected to the lower end of the support columns 21 arranged in a ring array, and the upper end of the support columns 21 arranged in a ring array is fixedly connected to the base plate 22.

The dual action breaks the van der Waals force and agglomeration force between particles, avoids agglomerated particles from being stuck on the screen surface or discharge channel, and makes the test data truly reflect the state of individual particles.

[0035] The bottom of the mixing and dispersing device 3 is fixedly installed with a mounting base 31, and a mixing tank 32 is provided at the top of the mounting base 31. A limiting ring 33 is fixedly connected to the bottom outer side of the mixing tank 32, and the bottom of the limiting ring 33 is connected to the mounting base 31. Multiple sets of first connecting plates 34 are fixedly installed on the edge of the mounting base 31, and the top of the first connecting plate 34 is fixedly connected to the outer side of the mounting base 31.

[0036] The top of the mounting base 31 is vertically mounted on the outer side of the limiting ring 33 with two sets of support plates 35. A circular top plate 36 is mounted on the top of the support plate 35. A gear disk 37 is mounted on the bottom of the top plate 36. A motor 38 is mounted at the center of the top of the top plate 36. The rotor of the motor 38 passes through the top plate 36 and is connected to the gear disk 37.

[0037] A second connecting plate 38 is installed on the inner side of each of the two sets of support plates 35, and a connecting platform 310 is fixedly installed at the intersection of the second connecting plates 38. A circular hole is opened through the center of the connecting platform 310, and a sliding ball 311 is slidably installed inside the circular hole. A stirring shaft 312 is connected through the inside of the sliding ball 311, and the bottom of the stirring shaft 312 is located inside the stirring tank 32. A gear 313 is sleeved on the top of the stirring shaft 312, and the gear 313 meshes with the gear disk 37. A first connecting sleeve 314 is sleeved on the outside of the stirring shaft 312, and a transmission rod 315 is fixedly installed on the outside of the first connecting sleeve 314. A second connecting sleeve 316 is fixedly connected to the end of the transmission rod 315, and the second connecting sleeve 316 is sleeved on the end of the rotor of the motor 38.

[0038] The mixing tank 32 is provided with a conical bottom plate 321 at the end, and a material trough 322 is provided at the bottom of the inner wall of the mixing tank 32. A pre-screen 323 is fixedly installed inside the material trough 322, and a discharge trough 331 is provided on the outer side of the pre-screen 323 inside the limiting ring 33. By adopting the above technical solution, the material is first added to the inside of the mixing tank 32. At this time, the motor 38 is started. The motor 38 drives the gear disk 37 to rotate through the rotor, so that the gear 313 meshing with it rotates synchronously, and further causes the mixing shaft 312 to rotate. Under the limiting action of the connecting table 310 and the sliding ball 311, the mixing shaft 312 rotates inside the mixing tank 32 and can also rotate along the inner wall of the mixing tank 32, stirring and separating the agglomerated particles. At this time, the separated fine particles can fall into the material trough 322 along the inclined surface of the conical bottom plate 321 at the bottom of the mixing tank 32, and finally fall into the inside of the primary screen 29 along the discharge trough 331 after passing through the pre-screen 323.

[0039] The working principle of this invention is as follows: Before the device is started, the control cabinet 15 completes the system self-test, and the status audible and visual alarm 16 displays the standby status; First, the material is added to the inside of the mixing tank 32. At this time, the motor 38 is started. The motor 38 drives the gear disk 37 to rotate through the rotor, so that the gear 313 meshing with it rotates synchronously, which further causes the mixing shaft 312 to rotate. Under the limiting action of the connecting table 310 and the sliding ball 311, the mixing shaft 312 rotates inside the mixing tank 32 and can also rotate along the inner wall of the mixing tank 32, stirring and separating the agglomerated particles. At this time, the separated fine particles can fall into the material trough 322 along the inclined surface of the conical bottom plate 321 at the bottom of the mixing tank 32, and finally fall into the primary screen 29 along the discharge trough 331 after passing through the pre-screen 323, completing the feeding. At the same time, the vibration motor 28 starts, driving the screen plate support 27, the primary screen plate 29 and the secondary screen plate 210 to generate high-frequency vibration, which initially disperses the material and breaks the agglomeration force between particles. The primary screen plate 29 first intercepts and screens large particles, and particles that meet the particle size requirements fall through the primary screen plate 29 into the secondary screen plate 210 to achieve secondary classification and dispersion. During this process, the damping spring 23, together with the support column 21 and the base plate 22, buffers the impact of vibration transmitted to the installation platform 12 and avoids frame shaking from affecting the detection accuracy. Fine particles passing through the secondary screen 210 fall into the fine material conical hopper 24 below, gather along the inner wall of the cone, and flow downward through the fine material discharge pipe 25; coarse particles remaining on the surface of the secondary screen 210 are guided by the adjustable baffle 211 through the coarse material discharge slot and discharged into the coarse material discharge channel 26. The fine particle detection camera 14 is fixed at the front end of the mounting frame 13 and aimed at the material flow area of ​​the fine material discharge pipe 25 to capture the dispersion state and particle size distribution of fine particles in real time; the screen plate particle detection camera 19 is installed at the lower end of the angle adjustment seat 18, and the shooting angle and position can be changed by adjusting the angle adjustment seat 18 to accurately capture the particle dispersion and grading dynamics of the first-stage screen plate 29 and eliminate shooting blind spots. The double-layer vibration dispersion structure of primary screen 29 and secondary screen 210, combined with the flow-guiding dispersion design of fine material conical discharge hopper 24, has a dual effect to break the van der Waals force and agglomeration force between particles, avoid agglomerated particles from being stuck on the screen surface or discharge channel, and make the test data truly reflect the state of individual particles. The fine particle detection camera 14 and the screen plate particle detection camera 19 form a complementary detection system, respectively covering the fine material discharge pipe 25 and the primary screen plate area; the screen plate particle detection camera 19 can flexibly adjust the shooting angle through the angle adjustment seat 18, completely eliminate the detection blind spot, accurately capture particle dynamics, and greatly improve the detection accuracy. The base plate 22 is connected to the mounting platform 12 by the support column 21 and the damping spring 23, which effectively buffers the impact of the vibration motor 28 during operation, avoids frame shaking, ensures the structural stability of the detection device, and reduces the interference of vibration on the detection data, thereby improving the reliability of the detection results. The adjustable baffle 211 can adjust the opening degree according to the discharge requirements of particles of different sizes, greatly improving its versatility.
