Description

Technical Field

[0001] The invention belongs to the field of pneumatic feeding, and in particular relates to a pneumatic feeding system and a feeding method for artemisinin semi-finished products. Background Art

[0002] As an important antimalarial drug, one of the key links in the production process of artemisinin is the efficient and accurate feeding of semi-finished products. In order to improve production efficiency and ensure product quality, pneumatic feeding systems have gradually been used to transport artemisinin semi-finished products. However, the pneumatic feeding systems commonly used in the market have significant defects in many aspects, which restrict their effective application in artemisinin production. First of all, the existing pneumatic feeding systems often cannot meet strict production requirements in terms of feeding accuracy. Since the pneumatic system relies on air pressure for material transportation, if the air pressure fluctuates or the pipeline is blocked, it will cause uneven material feeding, affecting the production quality of the semi-finished products. In the pharmaceutical industry, any slight error may lead to a decline in product quality, so improving the accuracy of feeding is an urgent problem to be solved.

[0003] The current pneumatic feeding system has deficiencies in material adaptability. The physical properties of artemisinin semi-finished products may have certain viscosity and particle size changes. The existing system is often difficult to adapt to the conveying needs of different materials, resulting in blockage, stratification or deterioration of materials during the conveying process, thereby affecting production efficiency and product quality. In addition, many pneumatic feeding systems are complex to operate and maintain, lacking user-friendly interfaces and intuitive operating instructions. In actual use, operators may need a long period of training to master the use of the system, which increases labor costs and training costs. At the same time, when the system fails, the maintenance and troubleshooting process is relatively cumbersome, which may cause the production line to stagnate and increase production losses.

[0004] Existing pneumatic feeding systems also have deficiencies in energy efficiency. Many systems consume high energy during operation, especially under high load conditions, which leads to increased production costs. In addition, the system's air source management is not optimized enough, which may lead to air waste, further aggravating the energy consumption problem. As environmental protection is increasingly valued today, it is particularly important to develop a more energy-saving and efficient feeding system. Finally, the current pneumatic feeding system is generally low in intelligence and automation, lacks data monitoring and feedback mechanisms, and cannot monitor the feeding status in real time. This makes it difficult for the system to conduct effective fault warnings and adjustments during operation, reducing production flexibility and response speed.

[0005] In order to solve the above problems, there is an urgent need for a new type of pneumatic feeding system for artemisinin semi-finished products, which can achieve high precision, wide adaptability, user-friendly operation interface and intelligent monitoring and control, so as to improve the overall efficiency and product quality of artemisinin production and meet the high standards of production technology in the modern pharmaceutical industry. Summary of the invention

[0006] The present invention proposes a pneumatic feeding system and feeding method for artemisinin semi-finished products, which solve the flow control and efficiency problems of artemisinin semi-finished products during transportation. By accurately adjusting the gas source output and flow detection, the semi-finished products can be stably and accurately transported to the designated location, thereby improving production efficiency and product quality.

[0007] The technical solution of the present invention is implemented as follows: an artemisinin semi-finished product pneumatic feeding system comprises an air source module, the air source module is used to output compressed gas; a feeding pipe module is connected to the air source module and the artemisinin semi-finished product bin through pipelines, and is used to receive the air source output by the air source module, output gas of corresponding size according to the obtained air source, and introduce the gas into the artemisinin semi-finished product bin to deliver the artemisinin semi-finished product in the artemisinin semi-finished product bin; the valve module comprises a main control valve, a first regulating valve, a second regulating valve, a first switch valve and a second switch valve, wherein the main control valve is arranged on the air source module The block is connected to the pipeline of the feeding pipe module; the first regulating valve and the first switch valve are respectively arranged on the connected pipeline and are located on the side of the main control valve away from the gas source module; the first end of the feeding pipe module is connected between the main control valve and the first regulating valve and the first switch valve; the second regulating valve and the second switch valve are arranged at the second end of the feeding pipe module; a flow detection and control module is arranged on the pipeline connecting the gas source module and the feeding pipe module to detect the flow of gas flowing through the pipeline and control the gas flow of the pipeline, and the main control valve and the first switch valve are electrically connected to the flow detection and control module.

[0008] Compared with the existing technology, this pneumatic feeding system has obvious advantages in the overall design of the system. Traditional pneumatic feeding systems usually use simple valves and fixed conveying gas sources, lacking the ability to monitor and adjust the airflow in real time, which may lead to problems such as unstable airflow and uneven material delivery during the conveying process. This instability not only affects the material delivery efficiency, but may also cause damage to artemisinin semi-finished products during the transportation process, affecting the quality of the final product. This system introduces a flow detection and control module to monitor the gas flow in real time and make precise adjustments to ensure that the delivery speed and flow can be maintained stable under any circumstances, thereby improving the efficiency and reliability of the entire delivery process.

[0009] The valve module design of this system is more complex, including multiple valves such as the main control valve, the first regulating valve, the second regulating valve, the first switch valve and the second switch valve, which can achieve more flexible control. Traditional systems usually only have basic switch valves, which make it difficult to achieve multi-stage regulation of airflow. However, this system can be flexibly adjusted according to different production needs through the combination of multiple regulating valves to meet different conveying process requirements. This flexibility enables the equipment to adapt to changes in different production batches and material properties, greatly improving the adaptability of the system.

[0010] Flow detection in the prior art mostly relies on simple mechanical flow meters, which lack intelligent control capabilities and cannot provide real-time feedback on the delivery status. In this system, the flow detection and control module is electrically connected to the main control valve and the first switch valve, which can achieve intelligent control and feedback. Through real-time monitoring of flow data, the system can automatically adjust the valve opening to ensure that the gas flow is always in the best state. This intelligent control method not only improves the automation level of the system, but also effectively reduces the errors of human operation and improves the accuracy and stability of delivery.

[0011] The connection design between the gas source module and the feeding pipe module of the system is also more reasonable. Traditional systems often have multiple connection links between the gas source module and the feeding pipe, which increases the complexity of the system and the risk of leakage. However, this system reduces unnecessary connection points and reduces the failure rate of the system through a simplified pipeline connection design, thereby improving the overall safety and reliability.

[0012] As a preferred embodiment, it also includes a first branch pipeline, which is connected between the main control valve and the first regulating valve and the first switch valve; a second branch pipeline is connected between the main control valve and the second regulating valve and the second switch valve; a second regulating valve front pressure detection module is arranged between the main control valve and the first regulating valve and the first switch valve; a second regulating valve post pressure detection module is arranged at the second end of the feeding pipe module downstream of the second regulating valve and the second switch valve; a silo air pressure detection module is arranged in the artemisinin semi-finished product silo; wherein, the second regulating valve front pressure detection module and the second regulating valve post pressure detection module are electrically connected to the flow detection and control module, the silo air pressure detection module is electrically connected to the control system, and the control system is electrically connected to the main control valve and the first switch valve and the second switch valve.

[0013] As a preferred embodiment, the air pressure detection module detects the air pressure values ​​of the silo air pressure detection module and the second valve post-regulating pressure detection module, obtains the air pressure value difference according to the air pressure value and the preset pressure value range, and transmits the air pressure value difference to the control system. The air pressure value difference controls the main control valve, the first switch valve and the second switch valve.

[0014] As a preferred embodiment, the control system compares the air pressure difference with a third preset threshold value. When the air pressure difference is greater than the third preset threshold value, the main control valve is controlled to open, the second switch valve is closed, and the first switch valve is controlled to open, wherein the third preset threshold value is greater than the second preset threshold value.

[0015] A method for pneumatically feeding artemisinin semi-finished products, the method comprising the following steps:

[0016] The compressed gas is output through the gas source module; then the feeding pipe module receives the gas source output by the gas source module through the pipeline, outputs gas of corresponding size according to the obtained gas source, and introduces the gas into the artemisinin semi-finished product silo to deliver the artemisinin semi-finished product in the artemisinin semi-finished product silo;

[0017] The gas source is controlled to flow into the feeding pipe module through the valve module; the flow detection module is used to detect the flow of the gas flowing through the gas pipeline and control the gas flow in the gas pipeline, and the gas source pipeline is a pipeline connecting the gas source module and the feeding pipe module; the valve module includes a main control valve, a first regulating valve, a second regulating valve, a first switch valve and a second switch valve, and the flow detection and control module is electrically connected to the main control valve, the first switch valve and the second switch valve;

[0018] The valve module is also electrically connected to a second pre-valve pressure detection module, a second post-valve pressure detection module and a silo air pressure detection module, the silo air pressure detection module is arranged in the artemisinin semi-finished product silo, and the second pre-valve pressure detection module and the second post-valve pressure detection module are arranged on a pipeline connecting the air source module and the feeding pipe module;

[0019] The silo air pressure detection module is used to detect the silo air pressure value; the pressure detection module is used to detect the air pressure values ​​of the second pre-valve regulating pressure detection module and the second post-valve regulating pressure detection module to obtain the first air pressure value and the second air pressure value; the control system is used to obtain the first air pressure value and the second air pressure value and calculate the pressure difference between the first air pressure value and the second air pressure value; the control system is used to compare the pressure difference value with a preset pressure value range, and the pressure difference value difference is obtained according to the pressure difference value and the preset pressure value range, and the main control valve, the first switch valve and the second switch valve are controlled according to the pressure difference value difference.

[0020] After adopting the above technical solution, the beneficial effect of the present invention is that the design of the system greatly improves the material transportation efficiency. Through the introduction of the flow detection and control module, the system can monitor the gas flow in real time and make precise adjustments to ensure that the artemisinin semi-finished product is transported at a stable speed. This stability not only improves the overall efficiency of the production line, but also reduces the material loss caused by uneven transportation, improves the utilization rate of materials, and thus reduces production costs.

[0021] The flexible valve module design enables the system to adapt to different production needs. During the production process, the properties of artemisinin semi-finished products may vary from batch to batch, and traditional systems often find it difficult to quickly adjust the conveying parameters. However, this system can quickly adjust the airflow and conveying speed according to different material properties and production requirements through the combination of multiple valves. This flexibility enables the production line to quickly respond to changes in market demand and improves production agility.

[0022] The intelligent control of the system significantly reduces the complexity of manual operation. Traditional systems require operators to manually adjust valves and monitor flow, which can easily lead to system failures due to improper operation. This system uses flow detection and control modules to achieve intelligent monitoring and automatic adjustment, reducing the need for manual intervention and making operation easier. This intelligent design not only improves the safety of operation, but also reduces the workload of operators.

[0023] The reliability and safety of the system are effectively guaranteed. The simplified pipe connection design reduces the risk of leakage. At the same time, the multiple valve design also allows the system to quickly switch to the backup plan when a failure occurs, ensuring that the production process is not affected. This safety design provides users with higher protection and makes the production process smoother and more efficient.

[0024] The precise flow control and efficient conveying capacity of the system make the production process of artemisinin semi-finished products more environmentally friendly and economical. By optimizing the use of air sources, energy waste is reduced, which meets the requirements of modern production for energy saving and environmental protection. This environmental benefit not only helps companies improve their social image, but also contributes to sustainable development. This artemisinin semi-finished product pneumatic feeding system provides an efficient, reliable and flexible solution for the production of artemisinin through innovative design and intelligent control, significantly improving production efficiency, reducing costs, and laying a good foundation for the sustainable development of enterprises.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figure 1 As shown, a pneumatic feeding system for artemisinin semi-finished products comprises an air source module, the air source module is used to output compressed gas; a feeding pipe module is connected to the air source module and the artemisinin semi-finished product bin through pipelines, and is used to receive the air source output by the air source module, output gas of corresponding size according to the obtained air source, and introduce the gas into the artemisinin semi-finished product bin to deliver the artemisinin semi-finished product in the artemisinin semi-finished product bin; the valve module comprises a main control valve, a first regulating valve, a second regulating valve, a first switch valve and a second switch valve, wherein the main control valve is arranged between the air source module and the feeding pipe module The first regulating valve and the first switch valve are respectively arranged on the connected pipeline and located on the side of the main control valve away from the gas source module; the first end of the feeding pipe module is connected between the main control valve and the first regulating valve and the first switch valve; the second regulating valve and the second switch valve are arranged at the second end of the feeding pipe module; a flow detection and control module is arranged on the pipeline connecting the gas source module and the feeding pipe module to detect the flow of gas flowing through the pipeline and control the gas flow of the pipeline, and the main control valve and the first switch valve are electrically connected to the flow detection and control module.

[0030] This technical solution involves a pneumatic feeding system for semi-finished artemisinin products, which aims to accurately and efficiently deliver semi-finished artemisinin products from a silo by means of compressed gas. The working principle and process of the system are mainly composed of multiple parts such as an air source module, a feeding pipe module, a valve module, and a flow detection and control module. These modules realize pneumatic delivery of semi-finished artemisinin products through precise collaboration.

[0031] The gas source module is the power source of the entire system, and its main function is to output compressed gas. When the system is started, the gas source module will be activated first to produce compressed gas of a certain pressure. The gas enters the feeding pipe module through the pipeline and provides power for the subsequent feeding process. The pressure and flow of the gas source module can be adjusted according to demand to meet the requirements for the delivery of artemisinin semi-finished products under different working conditions.

[0032] The feeding tube module forms a closed pneumatic conveying channel by connecting with the gas source module. When the gas source module outputs compressed gas, the gas pressure in the feeding tube module will rise rapidly. Through this process, the feeding tube module will generate a corresponding amount of gas flow according to the gas source pressure output by the gas source module, and introduce the gas into the artemisinin semi-finished product silo. The gas flow in this process can effectively push the artemisinin semi-finished product in the silo to the outlet of the feeding tube.

[0033] The function of the valve module is to precisely control the flow of gas. The module includes a main control valve, a first regulating valve, a second regulating valve, a first switch valve and a second switch valve. The main control valve is located on the connecting pipe between the gas source module and the feeding pipe module, and is responsible for overall control of the gas flow of the entire system. When the user needs to start feeding, the main control valve will be opened to allow gas to flow into the feeding pipe module. The first regulating valve and the first switch valve are respectively arranged on the side of the main control valve away from the gas source module, responsible for further adjusting the gas flow and opening or closing the gas flow. By adjusting the first regulating valve, the user can achieve detailed control of the gas flow to ensure that the delivery rate of the artemisinin semi-finished product meets the process requirements.

[0034] At the second end of the feeding pipe module, a second regulating valve and a second switch valve are also set. These valves are also used to control the opening and closing of the airflow to ensure that the artemisinin semi-finished product can flow smoothly into the subsequent processing equipment or storage container after being sent out. Through this double valve design, the system can achieve higher flexibility and control accuracy to meet the needs of different production environments.

[0035] The flow detection and control module is the intelligent control center of the entire system, which is installed on the pipeline connecting the gas source module and the feeding pipe module. This module is responsible for real-time detection of the gas flow through the pipeline and controlling the gas flow according to the set parameters. When the gas flow reaches the preset standard, the flow detection module will feedback the main control valve and the first switch valve through an electrical signal, thereby realizing automatic regulation of the gas flow. If the gas flow is too large or too small, the flow detection module will sound an alarm and automatically adjust the valve to keep the flow within a safe range. This intelligent control function not only improves the safety of the entire system, but also improves the delivery efficiency of artemisinin semi-finished products to a certain extent.

[0036] In terms of specific operation steps, the user first needs to set the working pressure and flow of the gas source module, which can be done by adjusting the control panel of the gas source module. Next, the user activates the main control valve through the control system, turns on the gas source module, and starts the pneumatic feeding process. After the gas source module outputs compressed gas, the flow detection and control module will monitor the gas flow in real time and automatically adjust the valve as needed to ensure smooth gas flow. During the feeding process, the user can fine-tune the flow by adjusting the first adjustment valve to meet production needs.

[0037] After completing the feeding of the artemisinin semi-finished product, the user can stop the airflow and end the feeding process by closing the first switch valve and the second switch valve. Finally, the user needs to turn off the air source module to ensure the safety of the system. Throughout the entire operation process, the system's intelligent monitoring and control functions can effectively reduce the burden on operators, improve production efficiency, and ensure the safe and rapid delivery of artemisinin semi-finished products. Through such design and implementation, the pneumatic feeding system demonstrates its important application value in modern pharmaceutical production.

[0038] As a preferred embodiment, it also includes a first branch pipeline, which is connected between the main control valve and the first regulating valve and the first switch valve; a second branch pipeline is connected between the main control valve and the second regulating valve and the second switch valve; a second regulating valve front pressure detection module is arranged between the main control valve and the first regulating valve and the first switch valve; a second regulating valve post pressure detection module is arranged at the second end of the feeding pipe module downstream of the second regulating valve and the second switch valve; a silo air pressure detection module is arranged in the artemisinin semi-finished product silo; wherein, the second regulating valve front pressure detection module and the second regulating valve post pressure detection module are electrically connected to the flow detection and control module, the silo air pressure detection module is electrically connected to the control system, and the control system is electrically connected to the main control valve and the first switch valve and the second switch valve.

[0039] The setting of the first branch pipeline enables the airflow to be diverted between the main control valve and the first regulating valve and the first switch valve. Such a design provides greater flexibility and can flexibly adjust the distribution and control of the airflow according to production needs. In the prior art, usually only a single airflow channel is used, lacking a flexible branch pipeline structure, which makes it difficult to effectively regulate the airflow under different production conditions. By setting a branch pipeline between the main control valve and the first regulating valve and the first switch valve, the system can achieve multi-channel control of the airflow and improve the ability to regulate different airflow paths.

[0040] The air pressure detection module detects the air pressure values ​​of the silo air pressure detection module and the pressure detection module after the second regulating valve, obtains the air pressure value difference according to the air pressure value and the preset pressure value range, and transmits the air pressure value difference to the control system, and the air pressure value difference controls the main control valve and the first switch valve and the second switch valve. The design of the pressure detection module before and after the second regulating valve enables the system to monitor the pressure changes of the airflow at different positions in real time. The existing technology often only focuses on the pressure of the gas source output, but ignores the pressure changes during the transportation process. By setting the pressure detection module before the second regulating valve, the system can obtain the air pressure data before the regulating valve in time, so as to judge whether the airflow is normal, and the pressure detection module set after the second regulating valve can monitor the air pressure of the feeding pipe module to ensure the stability of the airflow during the feeding process. This dual pressure monitoring design can timely detect potential airflow problems, such as insufficient or excessive air pressure, and feedback and adjustment through the electrically connected flow detection and control module, further improving the safety and reliability of the system.

[0041] The introduction of the silo air pressure detection module further enhances the overall monitoring capability of the system. This module can detect the air pressure inside the artemisinin semi-finished product silo in real time. Compared with the existing technology, this design provides a more comprehensive airflow and air pressure monitoring solution. Traditional systems usually only focus on the airflow conditions of the feeding pipeline and lack real-time monitoring of the air pressure inside the silo, which can easily lead to unstable silo air pressure during the feeding process, affecting the delivery efficiency of artemisinin semi-finished products. By electrically connecting the silo air pressure detection module to the control system, the system can take timely measures to adjust when abnormal air pressure is detected inside the silo to ensure a smooth feeding process.

[0042] In terms of air pressure detection and control, this technical solution detects the air pressure values ​​of the silo air pressure detection module and the second valve rear pressure detection module, calculates the air pressure difference, and transmits it to the control system. The fundamental difference between this mechanism and the prior art is that traditional systems often lack active monitoring and control of air pressure differences, resulting in the inability to accurately grasp the impact of air pressure changes on the feeding process when adjusting airflow. This solution can dynamically adjust the status of the main control valve, the first switch valve, and the second switch valve by real-time monitoring of the air pressure value and calculating the difference, thereby improving the system's adaptability to airflow and precise control capabilities.

[0043] The control system compares the air pressure difference with a third preset threshold value. When the air pressure difference is greater than the third preset threshold value, the main control valve is controlled to open, the second switch valve is closed, and the first switch valve is controlled to open, wherein the third preset threshold value is greater than the second preset threshold value.

[0044] The control system compares the air pressure difference with the third preset threshold value, so that the system can automatically adjust the opening and closing state of the valve according to the real-time air pressure conditions. Compared with the prior art, this design provides a more intelligent control mechanism, which can automatically open the main control valve and close the second switch valve when the air pressure difference is greater than the preset threshold, and open the first switch valve at the same time. This kind of automated control not only improves the response speed of the system, but also reduces the necessity of manual intervention and reduces operational risks. Traditional systems often rely on manual monitoring and adjustment, which makes it difficult to achieve rapid automated response and easily leads to operational errors caused by human factors. This solution ensures the stability and efficiency of the system under various working conditions by introducing an intelligent air pressure difference control mechanism.

[0047] The gas source is controlled to flow into the feeding pipe module through the valve module; the flow detection module is used to detect the flow of the gas flowing through the gas pipeline and control the gas flow in the gas pipeline, and the gas source pipeline is a pipeline connecting the gas source module and the feeding pipe module; the valve module includes a main control valve, a first regulating valve, a second regulating valve, a first switch valve and a second switch valve, and the flow detection and control module is electrically connected to the main control valve, the first switch valve and the second switch valve;
