Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing technology, and more specifically, to an anti-clogging material unloading system. Furthermore, this utility model also relates to pharmaceutical manufacturing equipment including the aforementioned anti-clogging material unloading system. Background Technology

[0002] Currently, during the unloading process of wet pellet mills, the unloading cylinder in the unloading system is either fully open or completely closed. When the unloading cylinder is fully open during unloading, a large amount of material is discharged from the unloading port, causing a large amount of material to accumulate at the screen of the pellet mill, which can lead to blockage and shutdown of the pellet mill, affecting the operation of the entire equipment.

[0003] Material blockage can also prevent the discharge valve from closing. Each time the machine stops due to blockage, manual intervention is required to clear the material from the discharge valve and the granulator screen before discharge can continue.

[0004] Currently, to prevent material blockage during wet granulation discharge, the agitator is operated intermittently, meaning the wet granulator runs for a period and then stops for a period. This method relies on adjusting the rotation angle of the agitator to control the amount of material entering the discharge port, reducing material accumulation at the granulator screen. However, the material state must be well-matched with the rotation angle of the agitator, which places high demands on the process parameters. Although this method can improve the material blockage problem in the discharge system to some extent, it cannot fundamentally solve the problem.

[0005] In conclusion, how to prevent material blockage in the unloading system is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] The core of this utility model is to provide an anti-blocking material unloading system, which can adjust the opening of the unloading valve to avoid material blockage during unloading.

[0029] Another core aspect of this invention is to provide a pharmaceutical production equipment that includes the aforementioned anti-blocking material unloading system.

[0030] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] This application provides an anti-blocking material unloading system for use in a wet granulation machine 1, comprising: a unloading valve 2, a unloading valve position detection component 3, and a control system;

[0032] Among them, the discharge valve 2 is located at the discharge port of the wet granulation machine 1;

[0033] The unloading valve position detection component 3 is connected to the unloading valve 2 and is used to detect the opening degree of the unloading valve 2;

[0034] The control system is connected to the unloading valve 2 and the unloading valve position detection component 3. The control system is used to control the opening degree of the unloading valve 2 to switch between at least three positions.

[0035] For details, please refer to the appendix. Figure 1 The anti-clogging material discharge system of this application is applicable to wet granulation machines 1, which are widely used in pharmaceutical, food, chemical and other industries. It is a device used to mix powder materials with liquid binders to form granules. A discharge valve 2 is provided at its discharge port. The opening and closing of the discharge valve 2 can control whether material is discharged. A discharge valve position detection component 3 is provided on the discharge valve 2. The discharge valve 2 is a solenoid valve and is connected to the control system. The control system can control the opening degree of the discharge valve 2. The discharge valve position detection component 3 can detect the opening degree of the discharge valve 2 and transmit the detection result to the control system. For the discharge valve 2, its opening degree includes at least a closed state with an opening degree of 0%, a fully open state with an opening degree of 100%, and a third opening degree between 0% and 100%. Adjusting the opening degree of the discharge valve 2 to the position corresponding to the third opening degree can realize the discharge of the wet granulation machine 1 and prevent the wet granulation machine 1 from discharging a large amount of material from the discharge port, thus avoiding screen blockage.

[0036] Optionally, the three opening degrees mentioned above each correspond to a gear in the control system. Adjusting the opening degree of the unloading valve 2 according to the gear can be more convenient and precise.

[0037] Based on the above embodiments, the unloading valve position detection component 3 includes an unloading cylinder 301 and an unloading valve position detection sensor 302. The unloading valve position detection sensor 302 is located at the output end of the unloading cylinder 301. The unloading cylinder 301 is used to control the opening degree of the unloading valve 2, and the unloading valve position detection sensor 302 is used to detect the opening degree of the unloading valve 2.

[0038] Specifically, the unloading cylinder 301 is installed on the unloading valve 2. The opening degree of the unloading valve 2 can be controlled by the action of the unloading cylinder 301. The unloading cylinder 301 includes a base and an output end. The output end can move laterally relative to the base. An unloading valve position detection sensor 302 is installed at the output end of the unloading cylinder 301. The unloading valve position detection sensor 302 can detect the moving distance of the output end of the unloading cylinder 301. The opening degree of the unloading valve 2 can be obtained according to the ratio of its moving distance to the maximum stroke of the unloading cylinder 301. In other words, when the stroke of the unloading cylinder 301 is 0, the opening degree of the unloading valve 2 is 0. When the stroke of the unloading cylinder 301 is the maximum stroke, the opening degree of the unloading valve 2 is 100%.

[0039] Optionally, a protective cover with graduations can be fitted onto the base of the unloading cylinder 301. This protective cover is used in conjunction with the unloading valve position detection sensor 302 to determine the opening degree of the unloading valve 2 according to the graduations.

[0040] Based on the above embodiments, the unloading valve position detection sensor 302 includes an open position detection sensor 3021, an intermediate position detection sensor 3022, and a closed position detection sensor 3023, and the open position detection sensor 3021, the intermediate position detection sensor 3022, and the closed position detection sensor 3023 are evenly distributed along the output end of the unloading cylinder 301.

[0041] Specifically, the unloading valve position detection sensor 302 of this application includes three position detection sensors: an open position detection sensor 3021, a middle position detection sensor 3022, and a closed position detection sensor 3023. The closed position detection sensor 3023 is located on the far right of the unloading cylinder 301. In the initial state, i.e., when the opening degree of the unloading valve 2 is 0, the closed position detection sensor 3023 opens and sends a signal to the control system. The middle position detection sensor 3022 is located at the middle position of the output end of the unloading cylinder 301, corresponding to a 50% opening degree of the unloading valve. When the unloading cylinder 301 moves... When the discharge valve 2 is opened and reaches 50% opening, the intermediate position detection sensor 3022 sends a signal to the control system. When the control system receives the signal from the intermediate position detection sensor 3022, it controls the discharge cylinder 301 to stop operating, maintaining the opening of the discharge valve 2 at about 50% and discharging material. Compared with the original discharge process, the amount of material is reduced by half, which will not cause blockage. However, an open position detection sensor 3021 is set on the far left of the discharge cylinder 301, corresponding to the 100% opening of the discharge valve 2. At this time, the discharge valve 2 is in a fully open state, which is the same as the discharge process of the prior art, and is prone to blockage.

[0042] Optionally, an alarm component, a braking component, and a limiting component can be additionally set. The alarm component, braking component, and limiting component are directly connected to the open position detection sensor 3021. When the open position detection sensor 3021 is activated, that is, when the unloading valve 2 is in a 100% open state, the alarm component and the braking component are immediately triggered. In this application, the unloading valve 2 being in a 100% open state is regarded as an operator's operational error or the control system having lost control of the unloading cylinder 301. The braking component can immediately stop the action of the unloading cylinder 301, the alarm component can immediately issue an alarm to remind the operator of operational error or equipment problems, and the limiting component can promptly block the unloading port, stop the unloading process, and avoid subsequent screen blockage.

[0043] Based on the above embodiments, the unloading valve 2 is also provided with an unloading valve detection sensor 4, which is used to detect the opening or closing of the unloading valve 2.

[0044] Specifically, each complete closure of the discharge valve 2 signifies the completion of one discharge cycle. The discharge valve detection sensor 4 is only used to detect whether the discharge valve 2 is closed normally. The discharge valve detection sensor 4 is also connected to the control system. When the discharge valve detection sensor 4 does not send a signal to the control system to confirm that the discharge valve 2 has been closed normally, the control system will not send a signal to the discharge valve position detection component 3 to avoid instruction errors in the equipment. In addition, when the discharge valve detection sensor 4 does not send a signal to the control system, the manual control mentioned later cannot control the discharge valve position detection component 3 to send a signal.

[0045] Based on the above embodiment, it also includes a pelletizing box 5, a pelletizing motor 6 and a discharge port 7, a discharge valve 2 connected to the pelletizing box 5, an output end of the pelletizing motor 6 located inside the pelletizing box 5, and a discharge port 7 connected to the pelletizing box 5.

[0046] Specifically, the discharge valve 2 is connected to the pelletizing box 5, that is, the material discharged by the discharge valve 2 enters the pelletizing box 5 for pelleting. A discharge port 7 is provided at the bottom of the pelletizing box 5. The pelletized material is discharged into fluidized bed or other equipment through the material pipe connected to the discharge port 7 for further processing.

[0047] Based on the above embodiment, the granulation box 5 is provided with a granulation screen and a granulation knife.

[0048] Specifically, the main function of the granulation screen is to screen wet particles and remove clumps or oversized particles. Only particles that meet the particle size requirements can pass through the screen's mesh, thus ensuring particle uniformity. The granulation blades, through high-speed rotation, crush and shear the wet particles, breaking up clumps or uneven particles and allowing them to pass through the screen to form uniform particles. It should be noted that the granulation blades are connected to the granulation motor 6, which drives the granulation blades to rotate at high speed.

[0049] In some embodiments, the control system includes a PLC controller, which is connected to the unloading valve 2, the unloading valve position detection sensor 302, and the pelletizing motor 6.

[0050] Specifically, the programmable logic controller (PLC) controls the solenoid valve by detecting the state of the unloading valve 2, thereby controlling the unloading cylinder 301 to control the opening degree of the unloading valve 2.

[0051] Based on the above embodiment, the PLC controller is electrically connected to the touch screen 8.

[0052] Specifically, the touch screen 8 is connected to the programmable logic controller (PLC) to input the controller's control signals and parameters, and to display the controller's output instructions.

[0053] Based on the above embodiment, the wet granulation machine 1 is provided with an observation window 9.

[0054] Specifically, an observation window 9 is provided on the wet granulator 1 to facilitate the operator's observation of the working status and unloading situation of the wet granulator 1, so as to ensure that the material in the wet granulator 1 is completely discharged and to avoid waste.

[0055] Based on the above, it should be further explained that the wet granulation production process is divided into several stages, including feeding, spraying, mixing, and unloading. During the unloading stage, the stirring paddle control mode needs to be changed to intermittent control mode, and then the opening size of the unloading valve needs to be selected. On the touch screen 8 interface, the opening degree of the unloading valve can be selected as 0%, 50%, or 100%. The opening size of the unloading valve 2 is controlled by the installation position of the sensor collected by the controller to control the action of the unloading cylinder 301, opening the unloading valve 2 to the selected opening degree.

[0056] When in manual control mode, you need to switch to the manual control interface on the touch screen 8. On the manual control interface, there are three discharge valve opening buttons for 0%, 50%, and 100%, and there is also a stirring paddle jog control button on the interface. You can also set the running time and stop time of the stirring paddle. After setting the stirring paddle jog parameters, you can click the stirring paddle jog button to run the stirring paddle, and then select the discharge valve opening button to discharge the material from the discharge port to the pellet mill for pelleting. The pelletized material is then discharged through the material pipe connected to the discharge port to the fluidized bed or other equipment for further processing.

[0057] During automatic control, the touchscreen 8 interface has a formula parameter setting page, which allows selection of continuous and discontinuous operation of the agitator. During the unloading stage, the agitator operation should be selected as discontinuous, and the running time and stop time of the agitation jogging should be set. The activation buttons for the 50% and 100% opening of the unloading valve can be set. After setting the formula for the unloading stage according to the process parameters, you can enter the automatic page to run the formula parameters. When the previous stage function is completed, the unloading stage function is entered. The agitator starts to rotate according to the set running and stop times, and then the unloading is carried out according to the opening selected in the formula.
