Abstract
Description
Technical Field
[0001] This invention relates to the field of feeding device technology, and more specifically to a rotary feeding device for homogenizing material conveying. Background Technology
[0002] In industrial production and warehousing logistics, the uniform transportation and homogenization of materials are key links to ensure production continuity and product consistency. They directly determine the stability of subsequent processes and the quality qualification rate of the final product. Whether it is the reaction of powder raw materials in the chemical industry, the grinding of cement clinker in the building materials industry, the mixing of raw materials in the food industry, or the sintering of mineral powder and the proportioning of alloy raw materials in the metallurgical industry, all have strict requirements on the stability of material transportation and the uniformity of components.
[0003] Existing homogenizing material conveying devices still have many shortcomings in practical applications. First, there is no accurate flow monitoring and signal conversion mechanism, making it impossible to capture changes in feed flow in real time. This easily leads to lag in the adjustment of bulk material and feeding, resulting in insufficient homogenization and feeding accuracy. Second, single rotary bulk material conveying relies on blade rotation speed, which can only "impact and break up" large clumps, but cannot break up sticky agglomerates. Single vibratory bulk material conveying has dead corners for material accumulation, resulting in poor uniformity of bulk material. In terms of adjustment methods, the blade angle of traditional bulk material conveying is mostly fixed or manually adjustable, which cannot be dynamically adapted to the flow rate. This results in incomplete bulk material dispersal at high flow rates and excessive material crushing at low flow rates. In addition, in terms of homogenization, mechanical stirring homogenization is prone to causing stratification of powder materials, and the wear of the stirring blade can introduce impurities, affecting product purity. As a result, existing equipment is difficult to meet the homogenization and conveying requirements of industries such as chemical and metallurgical industries for "high adaptability, high stability, and high precision". Finally, the coordination of various components is poor. There is a lack of intelligent linkage control in the flow monitoring, bulk material dispersal, feeding, and homogenization links, making it impossible to achieve adaptive adjustment. Summary of the Invention
[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a rotary feeder for homogenizing material conveying, which effectively solves the problems of lack of flow monitoring measures, poor homogenization effect of bulk materials, low component coordination, and insufficient control precision in existing technologies.

The variable frequency motor, micro motor, variable resistance rod, conductive coil, and fluidizer box are all electrically connected to the PLC controller. The circuit formed between the variable frequency motor, micro motor, variable resistance rod, conductive coil, fluidizer box, and PLC controller is electrically connected to an external power supply.
[0015] The technical solution provided by this invention has the following advantages compared with the known prior art:
[0016] 1. The present invention, through the material flow judgment component, can convert the flow parameter into a mechanical displacement signal by means of the impact between the judgment plate and the material. Combined with the reset function of the No. 1 spring, it can realize real-time and accurate monitoring of the feed flow. Compared with traditional equipment without flow monitoring, it can capture flow fluctuations in a timely manner, providing reliable data support for subsequent intelligent control and avoiding the problem of uneven material distribution caused by flow changes.
[0017] 2. The present invention, through the setting of the bulk material speed adjustment component, can convert the mechanical displacement signal of the material flow judgment component into an electrical resistance signal, and transmit it to the PLC controller to realize adaptive control of the speed of the two bulk material blades. In this way, the larger the feed flow, the larger the rotation angle of the judgment plate, the larger the sliding distance between the I-beam and the moving block, and the smaller the resistance value formed by the conductive ring sliding along the variable resistance rod. After receiving the signal, the PLC controller adjusts the variable frequency motor to increase the speed, thereby driving the corresponding bulk material blade to rotate faster, ensuring that the bulk material strength matches the feed flow and guaranteeing the bulk material effect.
[0018] 3. The present invention, through the setting of a high-efficiency material dispersing component, can drive the semi-circular vibrating column and the columnar protrusion on the functional column to achieve vibratory material dispersing by means of the rotation of the sleeve. At the same time, in combination with the rotational motion of the material dispersing blades, a dual material dispersing effect of "vibration + rotation" is formed. The material dispersing protrusion can effectively penetrate the material agglomeration, thoroughly break up sticky materials and large clumps, and the material dispersing effect far exceeds that of a single material dispersing method, thereby improving the basis of material homogenization.
[0019] 4. This invention, through its adaptive adjustment component, can provide stable tilt angle adjustment power for the material handling blades by means of precise transmission between a micro motor and a bevel gear set. This enables fine-tuning of the blade angle. Simultaneously, through linkage between the PLC controller and the flow signal, the two blades are driven to move synchronously, ensuring uniform material distribution. When the feed flow rate is large, the material handling blades are driven to increase the tilt angle, enhancing the frontal impact force with the material and ensuring the distribution effect. When the feed flow rate is small, the resistance value increases, and the PLC controller controls the micro motor to drive the blades to decrease the tilt angle, reducing the impact force and preventing the material from becoming excessively fine.
[0020] 5. The material homogenization component of this invention can convert compressed air into a uniform airflow through the fluidizer box, and spray it out through the air outlet to make the material fluidized. The homogenization uniformity is high and there is no material loss. It is suitable for various materials such as powders and granules. The electric push rod drives the angle adjustment of the mounting plate, which can flexibly change the blowing angle to adapt to different material characteristics and material level heights, resulting in better homogenization effect.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0034] The present invention will be further described below with reference to embodiments.
[0035] Example: Refer to Figures 1 to 10 A rotary feeding device for homogenizing material conveying includes a storage cylinder 1 and a base plate 11. The storage cylinder 1 is fixedly installed on the upper surface of the base plate 11. A variable frequency motor 12 is fixedly installed on the bottom surface of the base plate 11. A feeding assembly 2 is provided between the storage cylinder 1 and the variable frequency motor 12. The variable frequency motor 12 provides power to the feeding assembly 2 to drive it to convey the material in the storage cylinder 1. A PLC controller 13 is fixedly installed on the side wall of the storage cylinder 1. An annular baffle 14 is fixedly connected to the upper surface of the storage cylinder 1. A feed pipe 15 is fixedly connected to the inner wall of the annular baffle 14 through a bracket. A material flow judgment assembly 3 is provided in the feed pipe 15. A material dispersing speed adjustment assembly 4 is fixedly installed on the side wall of the annular baffle 14. Two high-efficiency material dispersing assemblies 5 and two adaptive adjustment assemblies 6 are provided in the storage cylinder 1. A material homogenization assembly 7 is provided below the base plate 11.
[0036] Both the bulk material speed adjustment component 4 and the adaptive adjustment component 6 are electrically connected to the PLC controller 13. The material flow rate judgment component 3 is used to collect the material flow rate parameters in the feed pipe 15 and feed them back to the PLC controller 13 through the material flow rate judgment component 3.
[0037] The feeding assembly 2 includes a first rotating shaft 21 fixedly connected to the output end of the variable frequency motor 12. A rotating column 22 is fixedly connected to the first rotating shaft 21 in the circumference. The rotating column 22 is rotatably connected to the upper surface of the base plate 11 through a bearing. Multiple feeding plates 23 are fixedly connected to the rotating column 22 in the circumference. A feeding port 24 is opened on the bottom surface of the base plate 11. A guide pipe 25 is fixedly connected to the output end of the feeding port 24. A feeding hopper 26 is fixedly connected to the output end of the guide pipe 25. A sleeve 27 is fixedly connected to the top end of the first rotating shaft 21. A semi-circular temporary storage plate 19 is fixedly connected to the inner wall of the storage cylinder 1. The semi-circular temporary storage plate 19 is located directly below the feed pipe 15. Two cleaning rods 110 are fixedly connected to the side wall of the sleeve 27. The bottom surface of the cleaning rods 110 is in contact with the upper surface of the semi-circular temporary storage plate 19.
[0038] The material flow judgment component 3 includes a judgment plate 31 rotatably connected to the inner wall of the feed pipe 15. A first through groove 32 is opened on the side wall of the feed pipe 15. An I-shaped block 33 is slidably connected in the first through groove 32. A connecting rod 34 is hinged to the side wall of the judgment plate 31. The connecting rod 34 is slidably connected through the side wall of the I-shaped block 33. A first spring 35 is fixedly connected between the I-shaped block 33 and the judgment plate 31.
[0039] This invention does not use a traditional electrical flow sensor, but instead designs a mechanically linked flow judgment component. The reason is that materials in industrial scenarios often contain dust and particulate impurities, and electrical sensors are easily clogged and fail. The mechanical structure is directly driven by the impact of the material, with no exposed electronic components. It is suitable for harsh working conditions with dust concentration ≥50g / m³ and material temperature ≤200℃. Moreover, the structure is simple, reliable, and has low maintenance costs. At the same time, through the reset action of the first spring 35, real-time response to flow fluctuations can be achieved (response time ≤0.5s), which solves the problem of lag in response of traditional mechanical flow valves.
[0040] The bulk material speed regulating component 4 includes a first C-shaped plate 41 fixedly connected to the side wall of the annular baffle 14. A variable resistance rod 42 is fixedly installed on the inner wall of the first C-shaped plate 41. A conductive ring 43 is slidably sleeved on the variable resistance rod 42. A second C-shaped plate 44 is fixedly connected to the upper end face of the conductive ring 43. A guide rod 45 is fixedly connected between the inner bottom surface and the inner top surface of the second C-shaped plate 44. A moving block 46 is slidably sleeved on the guide rod 45. The side end of the connecting rod 34 is fixedly connected to the side wall of the moving block 46.
[0041] This invention employs a 'mechanical displacement → resistance signal' conversion method, rather than directly receiving electrical sensor signals through a PLC. Its core advantage lies in achieving 'stepless linkage adjustment' of flow rate and material handling speed. The sliding of the conductive coil along the variable resistance rod can continuously change the circuit resistance, thereby making the variable frequency motor speed continuously adjustable (speed range 50-500 r / min). Compared with the traditional 'graded speed regulation', the matching accuracy between material strength and flow rate is improved, avoiding the problem of 'sudden change in material handling effect at the flow rate critical value' caused by graded speed regulation.
[0042] A connecting column 16 is fixedly connected to the side wall of the feed pipe 15 via a bracket. The connecting column 16 is rotatably connected to the inner top surface of the sleeve 27 via a bearing. A functional column 17 is fixedly connected to the bottom end of the connecting column 16. Multiple cylindrical protrusions 18 are installed on the circumferential side wall of the functional column 17. The high-efficiency material distribution assembly 5 includes a groove 51 opened in the inner bottom surface of the sleeve 27. A sliding block 52 is slidably connected in the groove 51. A semi-circular vibrating column 53 is fixedly connected to the upper surface of the sliding block 52. A second rotating shaft 54 is rotatably connected to the side wall of the semi-circular vibrating column 53 via a bearing. A sliding column 55 is fixedly connected to the first rotating shaft 54 in the circumferential direction. The sliding column 55 is slidably connected to the side wall of the sleeve 27. A material dispersing blade 56 is fixedly connected to the second rotating shaft 54 in the circumferential direction. Multiple material dispersing protrusions 57 are fixedly connected to the upper surface of the material dispersing blade 56. A circular plate 58 is fixedly connected to the side end of the sliding column 55 in the circumferential direction. A second spring 59 is fixedly connected between the circular plate 58 and the inner wall of the sleeve 27. Two high-efficiency material dispersing components 5 are respectively fixedly installed on both sides of the functional column 17. Both semi-circular vibrating columns 53 are in sliding contact with the side wall of the functional column 17.
[0043] The present invention designs a composite structure of 'semi-circular vibrating column 53 + columnar protrusion 18 + material dispersing blade 56' because a single rotating material dispersing blade can only act on the surface of the material, and a single vibrating material dispersing blade cannot form a directional impact force. However, in the composite structure, the intermittent contact between the columnar protrusion 18 and the semi-circular vibrating column 53 can generate high-frequency micro-vibration (vibration frequency 10-20Hz), breaking up the viscous agglomeration of the material. The rotation of the material dispersing blade 56 forms a directional impact force, breaking up large clumps. The two work together to achieve a material uniformity of over 95%. For viscous powder materials with a moisture content of 15%-25%, the material dispersing effect is improved compared to a single structure, solving the pain point that traditional simple structures cannot adapt to viscous materials.
[0044] The adaptive adjustment component 6 includes a micro motor 61 fixedly connected to the upper surface of the semi-circular vibration column 53 via a bracket. The output end of the micro motor 61 is fixedly connected to a third rotating shaft 62. The third rotating shaft 62 and the second rotating shaft 54 are connected by a bevel gear transmission.
[0045] The material homogenization component 7 includes a mounting plate 71 rotatably connected to the inner wall of the feed hopper 26. A fluidizer box 72 is fixedly mounted on the bottom surface of the mounting plate 71. An air outlet pipe 73 is fixedly connected to the output end of the fluidizer box 72, penetrating the upper surface of the mounting plate 71. An air inlet pipe 74 is fixedly connected to the input end of the fluidizer box 72, penetrating the side wall of the feed hopper 26. An electric push rod 75 is fixedly connected to the side wall of the feed hopper 26 via a bracket. A second through slot 76 is provided on the side wall of the feed hopper 26. The electric push rod 75... The outlet passes through the second through slot 76. A limit slot 77 is opened on the bottom surface of the mounting plate 71. A limit block 78 is slidably connected in the limit slot 77. The output end of the electric push rod 75 is hinged to the bottom surface of the limit block 78. The variable frequency motor 12, the micro motor 61, the variable resistance rod 42, the conductive ring 43, and the fluidizer box 72 are all electrically connected to the PLC controller 13. The circuit formed between the variable frequency motor 12, the micro motor 61, the variable resistance rod 42, the conductive ring 43, the fluidizer box 72, and the PLC controller 13 is electrically connected to an external power supply.
[0046] This invention is applicable to scenarios with stringent requirements for homogenization and conveying stability, such as high-viscosity powders in the chemical industry (e.g., polyvinyl chloride resin powder), cement clinker granules in the building materials industry, and mineral powders in the metallurgical industry (e.g., iron ore powder). It is especially suitable for working conditions with large flow fluctuations (fluctuation range ±30%) and complex material characteristics (viscosity / caking / dust).
[0047] The working principle of this invention is as follows: When in use, the material is introduced into the storage cylinder 1 through the feed pipe 15. When it flows through the feed pipe 15, it impacts the judgment plate 31, which pushes the judgment plate 31 to rotate around the hinge point. This causes the connecting rod 34 and the I-beam block 33 to slide along the first through groove 32. The first spring 35 is compressed, and the rotation angle of the judgment plate 31 increases with the increase of the material flow rate. This synchronously drives the moving block 46 to slide along the guide rod 45, which in turn drives the conductive ring 43 to slide along the variable resistance rod 42, changing the circuit resistance and converting the flow signal into an electrical signal, which is then transmitted to the PLC controller 13.
[0048] Among them, the resistance signal and the material flow rate are inversely related. The variable resistance rod 42 in the bulk material speed adjustment component is the core component. When the conductive ring 43 slides on its surface, it changes the resistance value of the circuit. The greater the material flow rate, the greater the rotation angle of the judgment plate 31, which drives the connecting rod 34 to push the moving block 46 to slide a farther distance. The sliding distance of the conductive ring 43 on the variable resistance rod 42 is also greater. The smaller the circuit resistance value, the weaker the resistance signal. The smaller the material flow rate, the smaller the rotation angle of the judgment plate 31. The reset force of the first spring 35 pushes the I-block 33 to slide in the opposite direction, which drives the conductive ring 43 to reset. The greater the circuit resistance value, the stronger the resistance signal.
[0049] The PLC controller 13 has preset data corresponding to the resistance value and the material flow rate. After receiving the resistance signal, it compares the real-time resistance value with the built-in data to accurately analyze the current material flow rate parameters. Based on the preset parameters, it outputs dual-channel control commands. Regarding the control logic of the variable frequency motor 12, when the resistance signal is weak (resistance value is small), it is identified as a high flow rate. The PLC controller 13 controls the variable frequency motor 12 to increase its speed, and the speed of the material dispersing blades increases accordingly, thus increasing the material dispersing strength. At the same time, the speed of the feeding plate increases, and the feeding amount increases. This ensures that the material dispersing strength matches the feed flow rate, and also ensures that the feeding amount matches the feed amount, thus ensuring the continuity of the conveying process. When the resistance signal is strong (resistance value is large), it is identified as a low flow rate. The PLC controller 13 controls the variable frequency motor 12 to decrease its speed, and the speed of the material dispersing blades decreases to avoid excessive dispersing of low-flow-rate materials, which could lead to uneven particle size. At the same time, the speed of the feeding plate decreases, and the feeding amount decreases synchronously to prevent material accumulation in the storage hopper and ensure the stability of the conveying process.
[0050] Regarding the control logic of the micro motor 61, when the flow rate is identified as high, the two micro motors 61 are controlled to operate synchronously, driving the second rotating shaft 54 to rotate through the bevel gear set, which in turn drives the corresponding material dispersing blade 56 to increase the tilt angle (the tilt angle refers to the acute angle between the material dispersing blade 56 and the horizontal plane), thereby increasing the frontal impact force with the material and improving the dispersing effect to handle more material. When the flow rate is identified as low, the micro motor 61 is controlled to drive the blade to decrease the tilt angle, weaken the impact force, and avoid excessive material refinement.
[0051] The sleeve 27 rotates synchronously with the first rotating shaft 21, causing the semi-circular vibrating column 53 to intermittently contact the columnar protrusion 18 on the functional column 17, pushing the semi-circular vibrating column 53 to slide back and forth, realizing vibration and material dispersal. At the same time, the angle-adjustable material dispersing blades 56 form a dual material dispersal of "vibration + precise impact", which not only thoroughly breaks up the clumps, but also ensures the stability of the material particle size.
[0052] After being dispersed, the material falls into the semi-circular temporary storage plate 19. The sleeve 27 drives the cleaning rod 110 to rotate, sweeping the material on the semi-circular temporary storage plate 19 to the feeding assembly 2. The discharge plate 23 rotates with the rotating column 22, pushing the material through the discharge port 24 and the guide pipe 25 into the feeding hopper 26. The fluidizer box 72 is started, and compressed air enters the fluidizer box 72 through the air inlet pipe 74. After being converted into a uniform airflow, it is sprayed out from the air outlet pipe 73, so that the material in the feeding hopper 26 is in a fluidized state, achieving efficient homogenization. During homogenization, the electric push rod 75 can be extended and retracted through the PLC controller 13, the angle of the mounting plate 71 can be adjusted, the blowing direction can be optimized, and the homogenization uniformity can be improved. The homogenized material is discharged from the bottom of the feeding hopper 26 and can then enter the subsequent process, which completes the material dispersion, homogenization and conveying process.
