Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically, to an automatic fluidized bed tilting and unloading system. Background Technology

[0002] In existing technologies, the common methods for unloading materials from a fluidized bed are using a hoist for tipping and unloading, or manual unloading. Both methods rely on human control. Specifically, during the fluidized bed unloading process, the material hopper needs to be moved out, and the material needs to be manually removed from the hopper and transferred to other transport equipment. This not only makes it impossible to control the unloading speed and time, but also poses a risk of contaminating the material during human intervention, which affects unloading efficiency and the purity of the final product. Furthermore, labor costs are relatively high.

[0003] There are also solutions that use guide plates for unloading. Specifically, when unloading is required, a person releases the gas from the sealing airbag on the outer periphery of the guide plate, then operates a drive pneumatic motor to rotate the guide plate, creating a gap so that the material can flow down through the gap. Then, the drive pneumatic motor is operated to return to its original position, so that the guide plate also returns to its original position. Finally, gas is filled into the sealing airbag to reseal the outer periphery of the guide plate, which allows for subsequent coating operations. While this approach avoids excessive human intervention and prevents human-induced contaminants from entering the material, reducing impurities and contamination, it still relies on human observation to determine the angle of the guide vane. Specifically, a person must judge whether the guide vane has reached the angle corresponding to the coating process before deciding whether to start inflating the sealing airbag. Similarly, during unloading, a person must judge the angle of the guide vane's rotation and the size of the gap left. It cannot precisely control the unloading speed. Therefore, there is an urgent need for a system that can automatically rotate and unload fluidized beds. Utility Model Content

[0036] The core of this utility model is to provide an automatic fluidized bed tilting and unloading system that can automatically determine whether the angle of the guide plate has reached the position corresponding to the sealing state without manual judgment and operation, and can more accurately control the unloading speed, completely avoiding the introduction of impurities into the material by humans, improving the purity of the product, and saving labor costs.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] An example of an implementation of the fluidized bed automatic tilting and unloading system provided by this utility model. Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of an automatic fluidized bed tilting and unloading system provided by this utility model. The automatic fluidized bed tilting and unloading system may include:

[0039] Control device 1, which may be, but is not limited to, a programmable logic controller (PLC), can control related drive devices to perform related operations based on external instructions or acquired parameters. This control device 1 may have an OPC UA interface, which can be connected to an MES data acquisition module or a SCADA data acquisition module. Through OPC UA technology, data acquisition between different systems can be facilitated to achieve centralized control, such as MES or SCADA data acquisition, to realize the intelligence of the system.

[0040] The guide vane status detection device 2 is electrically connected to the control device 1 and is used to transmit the guide vane status information to the control device 1. It should be noted that the guide vane status information mentioned here may include whether the guide vane is in a flipped state or a horizontal state. The flipped state corresponds to the unloading process, and the horizontal state corresponds to the normal production process. It may also include the specific flipping angle value. Detecting this flipping angle value can characterize the current unloading speed. After all, the larger the flipping angle, the larger the gap, and the more material is unloaded per unit time. By using precise control of the flipping angle, the unloading speed can be precisely controlled.

[0041] The deflector rotation drive device 3 is electrically connected to the control device 1. It is used to receive the rotation command from the control device 1 and rotate or stop the deflector according to the rotation command. Specifically, when a rotation command is received, the deflector can be rotated. When a stop rotation command is received, the deflector can be stopped. In actual operation, the deflector can be rotated within the range of 0 to 180°.

[0042] The guide plate sealing drive device 4 is electrically connected to the control device 1. It is used to receive sealing commands from the control device 1 and seal or unseal the guide plate according to the sealing commands. It should be noted that during normal production of fluidized beds, including pharmaceutical fluidized beds, the guide plate needs to be sealed to prevent powder leakage. However, when the fluidized bed is unloading, the guide plate needs to be unsealed to allow the guide plate to rotate. Therefore, this guide plate sealing drive device 4 is electrically connected to the control device 1 to receive relevant sealing commands. These sealing commands may include, but are not limited to, commands to seal the guide plate and commands to unseal the guide plate. This achieves automated control of the sealing and unsealing of the guide plate without manual intervention, thus avoiding the introduction of impurities into the guide plate and preventing contamination.

[0043] As can be seen from the above technical solution, in the embodiment of the fluidized bed automatic tilting unloading system provided by this utility model, since it includes a control device; a guide plate status detection device, electrically connected to the control device, for transmitting guide plate status information to the control device; a guide plate rotation drive device, electrically connected to the control device, for receiving rotation commands from the control device and rotating or stopping the rotation of the guide plate according to the rotation commands; and a guide plate sealing drive device, electrically connected to the control device, for receiving sealing commands from the control device and sealing or unsealing the guide plate according to the sealing commands, it can automatically determine whether the guide plate angle has reached the position corresponding to the sealing state without manual judgment and operation. Furthermore, by controlling the rotation angle of the guide plate, it can achieve more precise control of the unloading speed, completely avoid the introduction of impurities into the material by humans, improve the purity of the product, and save labor costs.

[0044] In a specific embodiment of the above-described fluidized bed automatic tilting and unloading system, refer to Figure 2 , Figure 2 This is a schematic diagram of a specific embodiment of an automatic fluidized bed tilting and unloading system. The aforementioned guide vane status detection device 2 may include:

[0045] Deflector tilt sensor 21;

[0046] The deflector state determination component 22 is electrically connected to the deflector tilt sensor 21 and is used to determine the state of the deflector based on the deflector tilt information.

[0047] In this case, the rotation angle of the guide vane is detected by the guide vane tilt sensor 21, and the guide vane state judgment component 22 judges the state of the guide vane based on the guide vane tilt angle. The state of the guide vane includes the normal state and the flipped-in state. This guide vane state information is transmitted to the control device 1, which can assist in the control of related processes without the need for manual judgment. This not only improves efficiency but also reduces production costs. Furthermore, the guide vane tilt sensor 21 can be mounted on the guide vane rotation shaft and located outside the material hopper of the fluidized bed. This ensures that the guide vane tilt sensor 21 remains synchronized with the guide vane rotation shaft at all times. When the guide vane rotation shaft rotates, the guide vane tilt sensor 21 also rotates synchronously. The detected tilt angle of the guide vane tilt sensor itself is then equal to the angle by which the guide vane rotation shaft has rotated, thus providing a basis for the control device to control unloading and production. Moreover, since the guide vane tilt sensor 21 is located outside the material hopper, it is not affected by the material inside the hopper and will not introduce contaminants. It is also easy to maintain and replace. Of course, it can be installed in other locations as needed; there are no restrictions. The guide vane tilt sensor 21 can be a capacitive tilt sensor, which calculates the tilt angle by measuring changes in electrode spacing. It features a simple structure and fast response speed. It can also be a single-axis tilt sensor, which can only measure the tilt angle in one direction, suitable for scenarios requiring tilt measurement in a single direction. Of course, other types can also be selected as needed; there are no restrictions. In addition, a screw hole can be opened on the aforementioned guide plate rotation shaft. After the screw passes through the base of the guide plate tilt sensor 21, it is screwed into the screw hole to fix the guide plate tilt sensor 21 and the guide plate rotation shaft. It can be seen that this can fix the two together more firmly and avoid falling off or loosening after long-term operation, which would lead to inaccurate tilt angle measurement.

[0048] Furthermore, refer to Figure 3 , Figure 3 This is a schematic diagram of the composition of a guide vane rotation drive device 3, which may include:

[0049] The front end of the pneumatic motor drive component 31 is fixedly connected to the rotating shaft of the guide plate.

[0050] The pneumatic motor solenoid valve 32 is connected to the pneumatic motor drive component 31 through an air passage and is electrically connected to the control device 1. It is used to control the opening and closing of the solenoid valve sub-unit therein according to the rotation command to control the pneumatic motor drive component 31 to rotate by a preset angle or stop rotating. Specifically, the pneumatic motor solenoid valve can preferably be a double-control two-position five-way solenoid valve or two single-control two-position five-way solenoid valves.

[0051] It should be noted that both the pneumatic motor drive component 31 and the pneumatic motor solenoid valve 32 can be located in the material hopper. The pneumatic motor drive component 31 drives the guide plate to rotate in a horizontal plane, achieving the flipping and unloading of the guide plate. This guide plate can rotate within a range of 0 to 180°. The pneumatic motor solenoid valve 32 controls the operation of the pneumatic motor, including forward and reverse rotation. It can accept control commands from the control device 1. According to the forward rotation command, the corresponding forward rotation air path can be opened, and according to the reverse rotation command, the corresponding reverse rotation air path can be opened. In addition, the guide plate rotation drive device 3 can also include a second compressed gas container, which is connected to the pneumatic motor solenoid valve 32 via a second pressure reducing valve for supplying air to the pneumatic motor. This provides a gas supply method, and the second pressure reducing valve can control the gas pressure for more precise drive. Of course, other methods can be selected according to actual needs, and there are no restrictions here.

[0052] Further, refer to Figure 4 , Figure 4 This is a schematic diagram of the composition of the guide vane sealing drive device. The guide vane sealing drive device 4 may include:

[0053] Gas pipe 41, the first end of which is connected to a sealing ring located on the outer periphery of the guide plate;

[0054] The venting solenoid valve 42 is installed on the gas pipeline 41 and is electrically connected to the control device 1. It is used to open when a venting command is received to release the gas in the sealing ring.

[0055] An inflation solenoid valve 43 is installed on the gas pipeline 41 and electrically connected to the control device 1. It is used to open when an inflation command is received to inflate the sealing ring.

[0056] It should be noted that during normal production of the pharmaceutical fluidized bed, the sealing ring around the outer periphery of the guide plate needs to be inflated to prevent powder leakage. However, during unloading, the sealing ring around the outer periphery of the guide plate needs to be deflated to allow the guide plate to rotate; otherwise, it will jam and cannot rotate. Therefore, when control device 1 receives an unloading command, it issues a deflating command to control the deflating solenoid valve 42 to release the gas from the sealing ring, and then rotation and unloading proceed. When control device 1 receives a normal production command, it issues an inflation command to control the inflation solenoid valve 43 to inflate the sealing ring, filling the gaps around the outer periphery of the guide plate and preventing powder from falling in during production, thus ensuring the safety of the production process. Further reference... Figure 4 The guide vane sealing drive device 4 may further include:

[0057] The first compressed gas container 44 is connected to the inflation solenoid valve 43 via a first pressure reducing valve 45 to supply gas to the sealing ring. In this configuration, the first compressed gas container 44 stores compressed gas. When the first pressure reducing valve 45 and the inflation solenoid valve 43 are opened, high-pressure gas can be supplied to the gas pipeline 41, ultimately entering the sealing ring on the outer periphery of the guide plate to inflate it, achieving a sealing effect and preventing leakage. Furthermore, the first pressure reducing valve 45 can adjust the pressure of the compressed gas to a suitable level. Additionally, a digital pressure switch for sealing and inflation can be included to detect the inflation and sealing pressure. When inflation occurs and the sealing pressure is lower than the digital set value (e.g., 2 bar), an alarm signal will be sent to the controller. The system may also include a touchscreen connected to the control device 1 for inputting control signals and parameters, and displaying the output commands of the control device.

[0058] To improve control precision, the aforementioned guide vane sealing drive device 4 may further include:

[0059] Pressure sensor 46 is installed on gas pipeline 41, located between venting solenoid valve 42 and charging solenoid valve 43, and electrically connected to control device 1. It transmits the detected pressure data to control device 1. In this configuration, control device 1 obtains a more accurate current pressure value, facilitating precise control. For example, if the current pressure is high, the pressure can be appropriately reduced, and vice versa. This avoids excessive impact on the sealing ring and prevents slow charging or venting speeds from affecting overall production efficiency.

[0060] In summary, the above-mentioned fluidized bed automatic tilting and unloading system enables continuous and intelligent production, provides more precise control over the tilt angle, avoids human intervention, and prevents contaminants from being introduced into the material.

[0061] refer to Figure 5 , Figure 5This is a schematic diagram of the fluidized bed automatic tilting and unloading system integrated with the fluidized bed. The fluidized bed 5 includes, from top to bottom, a material bin 51, a bottom pot 52, a discharge valve 53, and a discharge breather 54. The fluidized bed automatic tilting and unloading system installed on the fluidized bed 5 may include a guide vane status detection device 55, a guide vane rotation drive device 56, a guide vane sealing drive device 57, and a control device 58. The control device 58 is connected to the guide vane status detection device 55, the guide vane rotation drive device 56, and the guide vane sealing drive device 57. Electrical connections are used to achieve corresponding control. The deflector sealing drive device 57 may sequentially include a pressure reducing valve 571, a sealed inflation solenoid valve 572, and a sealed deflation solenoid valve 573. The pressure reducing valve 571 may be set to a pressure of 2.5 bar. It may also include a pressure sensor 574, with a minimum pressure that can be set to 2.0 bar. The deflector rotation drive device 56 may sequentially include a pressure reducing valve 561, a pneumatic motor solenoid valve 562, and a pneumatic motor drive component 563. The pneumatic motor solenoid valve 562 may be a dual-control two-position five-way solenoid valve.

[0062] When using the above system, the following steps may be included:

[0063] During normal production: the guide vane needs to be in a 0-degree rotation angle state, and the position and sealing status of the guide vane should be displayed in real time on the HMI interface; the guide vane sealing inflation button can be clicked to inflate the guide vane sealing ring only when the guide vane rotation angle is 0 degrees; the guide vane sealing ring cannot be inflated when the guide vane rotation angle is not 0 degrees; the guide vane rotation operation button on the HMI interface cannot be operated while the guide vane sealing ring is inflated.

[0064] During unloading: The system control is divided into manual control and automatic control. In manual production, the operator needs to switch to the manual HMI interface and control the degassing button of the guide plate to degas the guide plate sealing ring, so that the sealing ring is in an uninflated state. The operator can set the rotation angle of the guide plate on the HMI interface and use the rotation operation button of the guide plate to control the rotation angle of the guide plate, thereby controlling the unloading speed of the material. In automatic production, the operator needs to set the unloading stage and rotation angle in the formula, then switch to the automatic interface, call the set formula parameters, and when running to the unloading stage, the guide plate will automatically rotate to the set angle according to the rotation angle set in the formula to unload the material. In specific operation, the control device collects the signal of the guide plate tilt angle sensor through the analog module, controls the dual-control two-position five-way solenoid valve through the digital output module, and then controls the pneumatic motor drive device to realize the rotation of the guide plate. The output of the pneumatic valve controlled by the pneumatic valve island through PN communication controls the inflation and deflation solenoid valves of the guide plate to realize the inflation and deflation of the guide plate sealing ring. When the programmable logic controller (PLC) receives the desired rotation angle value for the air deflector, it controls the motor drive to rotate the air deflector. During the rotation of the air deflector, the tilt sensor detects the rotation position of the air deflector in real time. When the rotation angle of the air deflector reaches the rotation angle received by the PLC, the rotation of the air deflector stops.

[0065] The above system can be switched between manual and automatic control based on the interface. Manual control of unloading allows manual control of the guide vane according to the interface's left rotation, right rotation, forced rotation, and rotation angle. Automatic control mode requires setting the unloading stage and rotation angle in the formula. When entering automatic mode, the set formula parameters are called. When running to the unloading stage, the guide vane will automatically rotate to the set angle according to the rotation angle set in the formula to unload.

[0066] As can be seen, the guide vane status detection device of the above system includes an inclination sensor installed outside the material hopper. The inclination sensor detects the rotation angle of the guide vane and determines its status based on this angle. A pneumatic motor located in the material hopper drives the guide vane to rotate within a 0 to 180° range. Unloading is controlled by the pneumatic motor. The entire unloading process is implemented by a programmable logic controller (PLC), enabling automatic feeding of the wet granulation machine and the mixer, thus achieving intelligent and continuous production. The fluidized bed operation consists of several stages: feeding, drying, spraying, and unloading. These stages are executed sequentially according to a set time. After the previous stage of the unloading stage is completed, the PLC executes the unloading stage according to pre-set parameters, requiring no human intervention. This avoids the introduction of contaminants, resulting in a purer and higher-quality product.

[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
