Description

Technical Field

[0001] The utility model relates to the technical field of material shifting and unloading, in particular to a rotary material shifting and unloading device for difficult-flowing materials. Background Art

[0002] A discharger is a primary device for dust removal, air supply, and other feeding equipment. It is suitable for powdered and granular materials. Relying on the gravity of the material and the forced action of the feeder's working mechanism, it discharges the material from the bin and feeds it continuously and evenly to the next device. It can also serve as a feeding and unloading device for various mills, dryers, silos, and other equipment, suitable for drying powdered and small granular materials. Dischargers are commonly used in pneumatic output systems. For pressure or negative pressure output systems, the discharger evenly and continuously feeds the feed pipe to ensure a stable flow of gas and solids within the pipe, thereby enabling the proper functioning of the pneumatic conveying system. At the same time, it also isolates the upper and lower air pressures of the discharger, acting as a gas lock.

[0003] Currently, with the increasing number of industries in China involved in bulk material handling, the demand for silos and dischargers is also growing. However, automatic silo dischargers for highly viscous materials, lightweight materials, and various types of solid waste, such as high-moisture coal, peat, and sludge, have struggled to resolve the problems of clogging, sticking, and clumping. It is even more difficult to resolve the problem of entangled materials, such as paper scraps, RDF, SRF, tree bark, orange straw, and cloth strips, which can cause clogging and jamming of the discharger. Many industries still rely on primitive methods such as knocking, vibrating, and poking to fix silos. This is not only time-consuming, material-intensive, and costly, but also exacerbates the problems of clogging, entanglement, and jamming. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a rotary material discharging device for difficult-to-flow materials, through which the material with poor fluidity in the bin is continuously displaced to the discharge port, so that the material with poor fluidity can be continuously and stably discharged out of the bin.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides a rotary material discharging device for difficult-flowing materials, the device comprising: a bin body, a central bearing bearing seat;

[0006] There is a discharge port at the bottom of the silo, and the central bearing seat is arranged at the bottom center of the silo. A connecting shaft is assembled in the central bearing seat. The upper end of the connecting shaft is connected to the central rotating disk, and the lower end is connected to the reducer through the connecting disk.

[0007] A pair of material-diverting arms are symmetrically mounted on the side walls of the central rotating disk;

[0008] The connecting plate is flange-connected to the reducer;

[0009] The auxiliary transmission wheel forms a whole with the main transmission wheel through a transmission belt and is connected to the speed reducer. The main transmission wheel is key-connected to the rotating shaft of the driving motor.

[0010] Furthermore, the central load-bearing bearing seat is assembled by a matching bearing seat and a bearing, and the internal bearing is key-connected to the connecting shaft.

[0011] Furthermore, the material diverting arm is a flexible material diverting arm, wherein the two material diverting arms are installed at different heights, one close to the top of the side wall, and the other close to the bottom of the side wall.

[0012] Furthermore, the connecting plate is welded to the bottom of the silo, and the center is hollowed out so that the central bearing seat and the connecting shaft pass through; the connecting plate is a flange structure, provided with a first flange, and the first flange has an eyelet;

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The present invention incorporates a central rotating material-discharging device at the bottom of the silo, enabling continuous and stable discharge of materials with poor fluidity. The central rotating material-discharging arm rotates and distributes the poorly fluid materials to the silo outlet, achieving continuous and stable discharge and preventing clogging of the discharge port due to varying material flow rates during discharge. The material-discharging arm, while disturbing the material in the silo, allows the material above the silo to fall, preventing bridging and arching, thereby achieving continuous and stable discharge. The material-discharging arm is flexible and can retract inward when encountering material obstructions or other hard objects during rotation, reducing material-discharging resistance. When resistance is reduced, it automatically opens again to scrape material from the periphery of the silo, saving drive power and achieving high efficiency and energy conservation. The drive motor is connected to the main drive wheel, which rotates the secondary drive wheel via a transmission belt. The secondary drive wheel drives the reducer to transmit the driving force to the connecting shaft, which in turn rotates the connecting shaft. The connecting shaft then drives the central rotating disk and the material-discharging arm, enabling continuous and stable discharge of materials with poor fluidity along with the material-discharging arm.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Combine Figure 1 As shown, the utility model is a rotary material discharging device for difficult-flowing materials, comprising a bin body 1 and a central bearing bearing seat 2;

[0024] The central bearing seat 2 is provided at the bottom center of the silo 1. A connecting shaft 3 is assembled in the central bearing seat 2. The upper end of the connecting shaft 3 is connected to the central rotating disk 4, and the lower end is connected to the reducer 7 through the connecting disk 6.

[0025] A pair of material-dispensing arms 5 are symmetrically mounted on the side walls of the central rotating disk 4;

[0026] The connecting plate 6 is flange-connected to the reducer 7;

[0027] The auxiliary transmission wheel 9 forms a whole with the main transmission wheel 8 through the transmission belt 10 and is connected to the speed reducer 7. The main transmission wheel 8 is key-connected to the rotating shaft of the driving motor 11.

[0028] During the rotary unloading process of difficult-to-flow materials, the difficult-to-flow material first enters the silo from above and falls to the bottom. Simultaneously, the switch of drive motor 11 is turned on, controlling the rotation of the drive motor 11's shaft. Drive motor 11 is connected to main drive wheel 8. As the drive motor 11's shaft rotates, it drives the main drive wheel 8 to rotate synchronously. Auxiliary drive wheel 9 forms an integral unit with main drive wheel 8 via a transmission belt 10. Main drive wheel 8 drives auxiliary drive wheel 9 via transmission belt 10. Auxiliary drive wheel 9 is connected to speed reducer 7, driving the gears within speed reducer 7 to rotate. During the rotation of the gears, the speed of the input shaft often exceeds that of the output shaft due to the different speeds of the large and small gears, achieving a reduction in speed. Simultaneously, the output shaft of speed reducer 7 transmits the driving force to connecting shaft 3, rotating connecting shaft 3, which in turn drives the central rotating disk 4. The unloading arm 5 is symmetrically mounted on the sidewalls of rotating disk 4 and rotates around the center of the silo along with the central rotating disk 4. The lower half of the material in the silo body 1 rotates in the silo body 1 as the material diverting arm 5 rotates.

[0029] Combine Figure 2 As shown, the present invention is a rotary diverter unloading device for difficult-to-flow materials. A discharge port 1-1 is provided at the bottom of a silo 1. The lower half of the material in the silo 1 rotates with the rotation of the diverter arm 5. When the material reaches the discharge port at the bottom of the silo 1, it falls into the discharge port 1-1. Simultaneously, the diverter arm 5 disturbs the material in the silo 1, allowing the material in the upper portion to fall, thus avoiding bridging and arching, and achieving continuous and stable unloading.

[0030] In a preferred embodiment, the present invention can be further configured such that, if torque requirements are low, the center bearing block 2 and connecting shaft 3 can be omitted, and the center rotating disk 4 can be directly connected to the reducer 7 for rotation. In this case, the drive motor 11 rotates the main drive wheel 8, auxiliary drive wheel 9, and drive belt 10, transmitting the driving force to the reducer 7, which drives the gears within the reducer 7. The output shaft of the reducer 7 is directly connected to the center rotating disk 4 via a key or other fixed connection. Furthermore, the rotation of the center rotating disk 4 drives the material diverter arm 5, causing the material to move within the silo 1.

[0031] In a preferred embodiment, the present invention can be further configured as follows: the central bearing seat 2 is assembled from a matching bearing seat and a bearing, and the internal bearing is key-connected to the connecting shaft 3. The central bearing seat 2 is used to fix a bearing at the bottom of the tank body, and the bearing is key-connected to the connecting shaft 3. In this way, the connecting shaft 3 is fixed in the bearing but can rotate flexibly in the bearing. Through the central bearing seat 2, the reducer 7 can transmit the driving force to the connecting shaft 3, driving the connecting shaft 3 to rotate. The function of the connecting shaft 3 is to fix the central rotating disk 4 and transmit torque to rotate the central rotating disk 4.

[0032] In a preferred embodiment, the present invention can further be configured such that the material diverting arm 5 can be a flexible material diverting arm. The two diverting arms 5 are mounted at different heights, one near the top of the side wall and the other near the bottom. This flexible material diverting arm retracts inward when encountering material obstruction or other hard objects during rotation, reducing material diverting resistance. When resistance is reduced, it automatically opens again to scrape material from the periphery of the bin, saving drive power and achieving high efficiency and energy conservation. Furthermore, the two diverting arms 5 are mounted at different heights, ensuring more comprehensive material diversion.

[0033] In a preferred embodiment, the present invention can be further configured as follows: the connecting disk 6 is welded to the bottom of the silo 1, and the center is hollowed out to allow the center bearing seat 2 and the connecting shaft 3 to pass through; the connecting disk 6 is a flange structure, provided with a first flange, and the first flange has holes. The reducer 7 is provided with a second flange, and the second flange has holes. The connecting disk 6 and the second flange on the reducer 7 are connected by bolts, and the output shaft of the reducer 7 and the connecting shaft 3 are fixed by a coupling. The connecting disk 6 is hollowed out in the center, so as to prevent the center bearing seat 2 and the connecting shaft 3 from contacting the connecting disk 6. At the same time, the connecting disk 6 is arranged at the bottom of the silo 1 like the center bearing seat 2, but the connecting disk 6 is used to fix the reducer 7, while the center bearing seat 2 is used to fix the connecting shaft 3. The connecting plate 6 and the reducer 7 are matched with flanges, and the reducer 7 is fixed by bolts. At the same time, the output shaft of the reducer 7 and the connecting shaft 3 are fixed by a coupling. The coupling refers to the connection between two shafts or a shaft and a rotating part, which rotate together during the transmission of motion and power. It is used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. In addition to using a coupling to connect the output shaft of the reducer 7 and the connecting shaft 3, different methods of fixing the shafts can also be used, such as welding the output shaft of the reducer 7 and the connecting shaft 3. The reducer 7 includes an input shaft and an output shaft. The input shaft and the output shaft are both equipped with gears. They rotate through gears of different sizes, thereby making the speeds of the input shaft and the output shaft different to achieve the purpose of deceleration. At the same time, the reducer provides a stable speed for continuous and stable unloading.

[0034] In a preferred embodiment, the present invention can be further configured as follows: the input shaft on the lower right side of the reducer 7 is keyed to the secondary drive wheel 9, the secondary drive wheel 9 is connected to the main drive wheel 8 via a transmission belt 10, and the main drive wheel 8 is keyed to the rotating shaft of the drive motor 11. The input shaft of the reducer 7 is keyed to the secondary drive wheel 9, and the main drive wheel 8 is keyed to the rotating shaft of the drive motor 11. The keyed connection secures the shafts in the gears, and the rotation of the drive motor 11 drives the gears of the main drive wheel 8 to rotate. The driving force is transmitted between the main drive wheel 8 and the secondary drive wheel 9 via the transmission belt 10. The rotation of the main drive wheel 8 drives the rotation of the transmission belt 10, which drives the rotation of the secondary drive wheel 9. The secondary drive wheel 9 drives the input shaft of the reducer 7 to rotate, and the rotation of the gears inside the reducer 7 drives the output shaft to rotate.

[0035] In a preferred embodiment, the present invention can be further configured as follows: the drive motor 11 is placed below the reducer 7, and a PLC controller is provided below the silo 1, and the PLC controller is electrically connected to the drive motor 11. The presence of the PLC controller can control the forward and reverse rotation of the drive motor 11. The forward and reverse rotation of the drive motor 11 ultimately affect the forward and reverse rotation of the material diverter arm 5. In one case, the forward and reverse rotations can be alternately operated. If the material is tightly adsorbed during the forward rotation process, the material can be easily separated from the reverse direction by reversing, so that the material can flow more fully and will not be adsorbed in the silo 1.
