Description

Technical Field

[0001] This utility model belongs to the field of clean technology in pharmaceutical production, and in particular relates to a real-time dust removal and cleaning system for pharmaceutical production. Background Technology

[0002] In the pharmaceutical manufacturing process, whether it's the crushing and mixing of raw materials or the preparation of tablets and capsules, a large amount of dust is generated. This dust can not only lead to cross-contamination of drugs, affecting their purity and quality, but also harm the respiratory system of operators. Furthermore, dust accumulation to a certain level can pose safety hazards such as fire and explosion.

[0003] Currently, the dust removal methods commonly used by pharmaceutical manufacturing companies mainly include local dust collection equipment (such as single-unit bag filters) and simple cleaning tools (such as brooms and portable vacuum cleaners). However, existing technologies have significant drawbacks: 1. Local dust collection equipment can only collect dust generated by specific equipment and cannot cover the entire production area. Dust can easily spread to other corners of the workshop. Simple cleaning tools can cause dust to fly up again during the cleaning process, further aggravating pollution.

[0004] 2. Existing equipment is difficult to meet the strict requirements of the pharmaceutical industry for air cleanliness (such as Class A, Class B, Class C, and Class D). Some dust collectors have insufficient filtration accuracy and cannot filter fine dust particles. Moreover, the equipment itself is prone to dust accumulation, becoming a new source of pollution.

[0005] 3. The dust removal system and the cleaning system are independent of each other and cannot work together. For example, the dust removal function cannot be activated simultaneously during the cleaning process, resulting in the inability to control the dust diffusion problem in real time.

[0006] 4. The filter components of the existing equipment need to be replaced frequently, and dust leakage is easily caused during the cleaning process. At the same time, the equipment lacks intelligent monitoring functions, which makes it impossible to detect faults or filter blockage problems in time, affecting the continuous and stable operation of the system. Utility Model Content

[0007] In view of this, the present invention aims to provide a real-time dust removal and cleaning system for pharmaceutical production, in order to solve at least one technical problem in the background art.

[0008] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A real-time dust removal and cleaning system for pharmaceutical production includes several dust removal and cleaning subsystems; The exhaust ends of several dust removal and cleaning subsystems are connected in parallel through exhaust pipes; The dust removal and cleaning subsystem includes a dust removal device, an explosion-proof isolation valve, a first pressure sensor, a dust collector assembly, a pneumatic switching valve, and a fan connected in sequence. The gas enters the dust collector assembly sequentially from the dust removal device, the explosion-proof isolation valve, and the first pressure sensor, and is discharged after passing through the pneumatic switching valve and the fan. The dust removal device includes a vacuum cleaning dust removal component, a production equipment dust removal component, and a suction hood dust removal component arranged in parallel; the vacuum cleaning dust removal component, the production equipment dust removal component, and the suction hood dust removal component are connected in parallel through a main pipeline, which is connected to an explosion-proof isolation valve; Vacuum cleaning and dust removal components are installed on the walls of the cleanroom; Dust removal components for production equipment are installed at the dust-generating points of the process production equipment; The dust collection hood assembly is installed above the production equipment or workbench.

[0009] Furthermore, the dust collector assembly includes a high negative pressure dust collector; The top of the high negative pressure dust collector is equipped with a flameless explosion relief device; the flameless explosion relief device is a combination of an explosion relief disc and a flame extinguishing net. The explosion relief disc quickly releases pressure and works with the flame arresting net to extinguish the flame, preventing damage to people and the surrounding environment.

[0010] Furthermore, a pneumatic switching valve is installed on one side of the upper part of the high negative pressure dust collector.

[0011] Furthermore, a dust hopper is provided below the high negative pressure dust collector, and a star-shaped discharge valve is installed below the dust hopper; A dust collection bin is located below the star-shaped discharge valve.

[0012] Furthermore, a level gauge is installed on the lower side of the star-shaped discharge valve.

[0013] Furthermore, the vacuum cleaning and dust removal assembly includes Vacuum cleaning and dust removal pipeline, first manual regulating valve, wall valve; One end of the vacuum cleaning and dust removal duct is installed on the wall of the clean room, and the other end is connected to the main duct. The first manual regulating valve and the wall valve are installed sequentially on the vacuum cleaning and dust removal pipeline.

[0014] Furthermore, the dust removal components for the production equipment include a dust removal duct for the production equipment and a second manual regulating valve; One end of the dust removal duct of the production equipment is set at the dust generation point of the process production equipment; the other end of the dust removal duct of the production equipment is connected to the main duct. The second manual regulating valve is installed on the dust removal pipeline of the production equipment.

[0015] Furthermore, the suction hood dust removal assembly includes a suction hood dust removal duct, a third manual adjustment valve, and a universal suction arm; One end of the dust collection hood's dust removal pipe is set above the production equipment or workbench, and the other end is connected to the main pipe; The third manual regulating valve and the universal suction arm are sequentially installed on the dust removal pipe of the dust hood.

[0016] Furthermore, the dust removal device also includes a reserved pipeline, which is connected to the main pipeline, and a reserved manual regulating valve is provided on the reserved pipeline.

[0017] Furthermore, the pipes between the dust collector components of several dust removal and cleaning systems and the first pressure sensor are connected in parallel through the air intake pipe.

[0018] Furthermore, it also includes a reserved fan, which is connected to the exhaust pipe through a pipe, and the reserved fan is connected to the pipe between the fan and the pneumatic switching valve in several dust removal and cleaning systems through a pipe.

[0019] Compared with existing technologies, the real-time dust removal and cleaning system for pharmaceutical production described in this utility model has the following advantages: 1. This application sets up three dust removal components: vacuum cleaning, fixed-point dust removal for production equipment, and suction hood. The system can cover all aspects of dust generation from inside the equipment and dust on the workbench to ground cleaning, truly achieving effective capture of dust at the source and strongly ensuring that the pharmaceutical production environment meets GMP requirements.

[0020] 2. The explosion-proof isolation valve of this application can quickly cut off a single path in case of abnormality, preventing the spread of the accident. The flameless explosion relief device can safely release high-pressure explosions and extinguish flames, preventing damage to surrounding personnel, the environment, and equipment. Temperature and pressure sensors form an early warning network that can promptly detect abnormal temperature rises and blockage risks. The PLC system implements safety interlocks; once a danger signal is detected, it automatically performs shutdown and isolation operations to minimize risks.

[0021] 3. The modular, parallel subsystem design of this application allows the system to be flexibly expanded as production scales up. Reserved piping and manual regulating valves facilitate the future connection of new dust-generating points. This design provides the system with excellent investment protection and adaptability.

[0022] 4. The design of the reserved fan in this application constitutes an effective backup plan. When any main fan fails, the backup system can quickly take over, ensuring the uninterrupted operation of the corresponding dust removal subsystem, thereby avoiding interruptions in related production processes due to the shutdown of the dust removal system and ensuring the smooth execution of the production plan.

[0023] 5. The high negative pressure dust collector of this application ensures high filtration efficiency and reduces emissions. Centralized dust collection and treatment reduce cleaning costs. The system's automated operation and early warning functions also reduce labor costs and production downtime losses due to equipment failure, resulting in significant economic benefits in the long run.

[0030] like Figure 1 As shown, a real-time dust removal and cleaning system for pharmaceutical production includes several dust removal and cleaning subsystems. The exhaust ends of the several dust removal and cleaning subsystems are connected in parallel through an exhaust pipe 1. Each dust removal and cleaning subsystem includes a dust removal device, an explosion-proof isolation valve 7, a first pressure sensor 5, a dust collector assembly, a pneumatic switching valve 3, and a fan 2 connected in sequence. Gas enters the dust collector assembly sequentially from the dust removal assembly, the explosion-proof isolation valve 7, and the first pressure sensor 5, and is discharged through the pneumatic switching valve 3 and the fan 2. The dust removal assembly includes a vacuum cleaning dust removal assembly 8, a production equipment dust removal assembly 9, and a suction hood dust removal assembly 10 arranged in parallel. The vacuum cleaning dust removal assembly 8, the production equipment dust removal assembly 9, and the suction hood dust removal assembly 10 are connected in parallel through a main pipe 11, which is connected to the explosion-proof isolation valve 7. Vacuum cleaning and dust removal assembly 8 is installed on the cleanroom wall; production equipment dust removal assembly 9 is installed at the dust generation point of the process production equipment; suction hood dust removal assembly 10 is installed above the production equipment or workbench.

[0031] The dust collector assembly includes a high-negative-pressure dust collector 4. The top of the high-negative-pressure dust collector 4 is equipped with a flameless explosion relief device 12, which is a combination of an explosion relief disc and a flame extinguishing net. The explosion relief disc rapidly releases pressure, and the flame is extinguished in conjunction with the flame arrestor net to prevent damage to people and the surrounding environment. A temperature sensor 13 is located on one side of the upper part of the high-negative-pressure dust collector 4, and a filter cartridge differential pressure controller 16 is located on one side of the high-negative-pressure dust collector 4. A dust hopper is located at the bottom of the high-negative-pressure dust collector 4, and a rotary valve 14 is installed below the dust hopper. A dust collection bin 15 is located below the rotary valve 14.

[0032] A level gauge 17 is provided on the lower side of the star-shaped discharge valve 14.

[0033] The vacuum cleaning and dust removal assembly 8 includes a vacuum cleaning and dust removal pipe 801, a first manual regulating valve 802, and a wall valve 803; one end of the vacuum cleaning and dust removal pipe 801 is installed on the cleanroom wall, and the other end is connected to the main pipe 11; the first manual regulating valve 802 and the wall valve 803 are sequentially installed on the vacuum cleaning and dust removal pipe 801.

[0034] The dust removal assembly 9 for production equipment includes a dust removal pipe 901 and a second manual regulating valve 902. One end of the dust removal pipe 901 is located at the dust generation point of the process production equipment. The other end of the dust removal pipe 901 is connected to the main pipe 11. The second manual regulating valve 902 is located on the dust removal pipe 901.

[0035] The dust removal assembly 10 includes a dust removal hood duct 1001, a third manual regulating valve 1002, and a universal suction arm 1003. One end of the dust removal hood duct 1001 is located above the production equipment or workbench, and the other end is connected to the main duct 11. The third manual regulating valve 1002 and the universal suction arm 1003 are sequentially arranged on the dust removal hood duct 1001.

[0036] The dust removal device also includes a reserved pipe 6, which is connected to the main pipe 11. A reserved manual regulating valve 19 is provided on the reserved pipe 6. It also includes a reserved fan 18, which is connected to the exhaust pipe 1 through a pipe. The reserved fan 18 is connected to the pipes between the fans 2 and pneumatic switching valves 3 in several dust removal and cleaning systems through pipes. Example

[0037] like Figure 2 , 3As shown, fan 2, reserved fan 18, pneumatic switching valve 3, first pressure sensor 5, explosion-proof isolation valve 7, first manual regulating valve 802, wall valve 803, temperature sensor 13, rotary valve 14, level gauge 17, and filter cartridge differential pressure controller 16 are all electrically connected to the PLC controller. The PLC controller adopts existing PLC technology and is electrically connected to the DCS (Distributed Control System), which in turn is electrically connected to the MES (Manufacturing Execution System). Through three-level control via PLC, DCS, and MES, the system achieves unattended automatic operation, fault warning, and remote monitoring. The filter cartridge differential pressure controller 16 and level gauge 17 automatically prompt for maintenance needs, reducing manual intervention, improving management efficiency, and providing support for preventative maintenance and data analysis.

[0038] Fan 2 and reserved fan 18 are both high negative pressure fans 2, located at the end of the system. These high negative pressure fans 2 are frequency conversion explosion-proof and can automatically adjust the airflow according to the system pressure, preventing excessive airflow from causing dust diffusion or insufficient airflow from affecting dust removal efficiency. This fan 2 can be used for centralized dust removal under high airflow and low negative pressure conditions, as well as for vacuum cleaning under low airflow and high negative pressure conditions. The high negative pressure fan 2 is existing technology and can be in the form of a multi-stage centrifugal fan, a high-pressure vortex fan, a Roots blower, etc.

[0039] The high negative pressure dust collector 4 adopts existing technology, with differential pressure sensors installed on the inside and outside of the filter cartridge to monitor the filter material blockage in real time. Compressed air is used for backflushing according to the pressure difference to ensure the filter element's performance and extend its service life. This system consists of a common backup unit and multiple parallel dust removal units.

[0040] The common backup unit includes a reserved fan 18, which is connected to all dust removal units via a duct network and can be automatically started in the event of a failure of the active fan 2 in any unit, ensuring continuous system operation.

[0041] This application includes multiple dust removal and cleaning subsystems, each of which is an independent air network system responsible for dust treatment in a specific area. The exhaust ends of all dust removal units are connected in parallel through exhaust pipe 1.

[0042] The airflow path of a single subsystem is: dust source, dust removal device, explosion-proof isolation valve 7, first pressure sensor 5, high negative pressure dust collector 4, pneumatic switching valve 3, fan 2, and parallel exhaust pipe 1.

[0043] The dust removal device is connected to different dust sources through several dedicated pipes, and is then connected to the system through the main pipe 11.

[0044] The vacuum cleaning and dust removal assembly 8 is used for regular cleaning. One end of the vacuum cleaning and dust removal pipe 801 is embedded in the clean room wall through the wall valve 803, which facilitates the connection of cleaning tools (the wall valve 803 can be connected to several adsorption pipes to adsorb different locations).

[0045] A first manual regulating valve 802 and a wall valve 803 are installed sequentially on the vacuum cleaning and dust removal system. The first manual regulating valve 802 is used to adjust the suction power, and the wall valve 803 is used to shut off the pipeline when not in operation to prevent ambient air from entering the dust removal system.

[0046] The dust removal component 9 for production equipment is used for fixed-point dust removal: the suction port of the dust removal pipe 901 is directly fixed to the dust generation point of the process equipment (such as a crusher or tablet press). A second manual regulating valve 902 is installed on the pipe to balance the air volume at each suction point.

[0047] The suction hood dust collection assembly 10 is used for encircling dust collection. The suction hood is suspended above the mixing, batching and other dust-prone work areas via the universal suction arm 1003. The universal suction arm 1003 is connected to a third manual regulating valve 1002 and a dust collection hood dust collection pipe 1001.

[0048] A reserved pipe 6 is led out from the main pipe 11, and a reserved manual regulating valve 19 is installed. The valve is then sealed to leave an interface for future new equipment.

[0049] A flameless explosion relief device 12 is installed on the top of the dust collector. The flameless explosion relief device 12 is a combination of an explosion relief disc and a flame extinguishing net. The explosion relief disc quickly releases pressure and works with the flame arrestor net to extinguish the flame, preventing damage to people and the surrounding environment.

[0050] A star-shaped discharge valve 14 is installed under the ash hopper at the bottom of the dust collector to achieve continuous and sealed ash discharge. A dust collection bin 15 is placed below it to collect dust.

[0051] The system monitors the pipeline pressure and the temperature inside the dust collector in real time. If the pipeline pressure exceeds the standard due to an explosion, the pressure is released in a timely and directional manner through the flameless explosion relief device 12. The star-shaped unloading valve 14 prevents sparks or explosive gas from entering the dust collector housing, ultimately ensuring the safety of equipment and personnel.

[0052] A filter cartridge differential pressure controller 16 is installed in dust collector 3 to monitor whether the pressure difference inside and outside the filter cartridge reaches the state of compressed air backflushing or replacement, ensuring the filtration effect of the dust collector filter cartridge. A level gauge 17 is installed on the dust collection bin 15 of the dust collector to indicate that it is full of dust.

[0053] All connecting pipes in this application are made of stainless steel with smooth inner walls to reduce dust accumulation.

[0054] Each subsystem has one fan (2), which is the source of negative pressure in the system. Explosion-proof type should be selected, and the air volume, air pressure, and system resistance should be matched.

[0055] The reserved fan 18 is installed independently, and its inlet and outlet pipes are connected in parallel to the exhaust and intake ends of each subsystem through valves. When any fan 2 fails, the standby fan 2 can be started and the corresponding valves switched to take over the operation of the failed subsystem.

[0056] All exhaust pipes 1 of the subsystems are connected in parallel after fan 2, and are ultimately discharged outdoors or to a treatment unit. All sensors and actuators (fan 2, valves, sensors, etc.) are connected to the PLC controller. The PLC is connected to the plant-level DCS system to achieve remote monitoring from the central control room. The DCS is connected to the MES system to achieve information management of production data, energy consumption, and maintenance records. Operators confirm that all manual regulating valves are at the correct opening degree and that dust collection bin 15 has been emptied. Start commands are issued via MES / DCS or local touch screen.

[0057] The PLC starts the rotary valve 14 according to the program, and then starts the blower 2.

[0058] The system generates negative pressure, drawing dust in through one of the three dust collection components. The dust-laden air enters the high-negative-pressure dust collector 4, where the dust is trapped by the filter element. The purified air passes through the filter element and is discharged into the exhaust pipe 1 via the fan 2. The filter cartridge differential pressure controller 16 monitors the dust collector resistance in real time. When the resistance reaches a set value, the pulse jet cleaning program is activated. The trapped dust falls to the bottom and is discharged into the dust collection bin 15 by the continuously operating rotary valve 14.

[0059] When the level gauge 17 detects that the dust collection bin 15 is full, it sends an alarm to the MES system, prompting personnel to replace it. For overheating alarms and shutdowns, if the temperature sensor 13 detects an abnormal gas temperature (such as that caused by friction or an ignition source), the PLC immediately issues an audible and visual alarm and interlocks to shut down fan 2, isolating the hazard source. If fan 2 malfunctions, the system automatically (or prompts the operator to manually start) the reserved fan 18 and switches the corresponding pipeline valve 3 to ensure production continuity. All alarm events, maintenance operations, and filter replacement cycles are recorded by the MES system for trend analysis and continuous improvement.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
