Description

Technical Field

[0001] The invention relates to the technical field of tobacco processing, in particular to a multi-stage filtering flavoring and feeding pipeline system. Background Art

[0002] The current tobacco flavoring and feeding pipeline system faces many technical challenges. First of all, the cost issue is one of the main pain points. Due to the insufficient filtration efficiency of the traditional single-stage filtration system, the filter medium needs to be frequently replaced or manual cleaning is performed, which increases the operating cost. In addition, the production downtime caused by manual cleaning also directly increases the additional time cost and potential material waste. Inefficiency is another significant technical problem. Suspended particles and precipitation in the feeding can easily lead to blockage of pipelines and flow meters, which not only affects the stability of the flow, but also destroys the precise ratio of flavoring and feeding, thereby affecting the quality of the final product. When the production line is frequently shut down due to blockage, the production efficiency of the entire system is significantly reduced. Structural complexity is also a defect of the existing technology. Many current system designs contain multiple The large number of mechanical parts and connection points not only increases the risk of failure, but also makes maintenance and cleaning more difficult and time-consuming. The complex structure means higher initial investment and subsequent maintenance costs. Slow speed is also a prominent problem. When traditional filtration systems process high-viscosity or high-particle-loaded feeds, the flow rate is often significantly limited, which limits the flexibility and adaptability of the production line. This is especially important for production environments that require rapid switching between different formulations. In addition, existing systems generally lack real-time monitoring and automated cleaning functions and cannot effectively prevent and respond to blockage events. The lack of automation results in increased dependence on operators and reduced system stability and reliability. Manual monitoring methods are often not accurate enough and have delayed response times, making it impossible to effectively optimize production processes.

[0003] Therefore, the technical problems faced by traditional tobacco flavoring and feeding pipeline systems include but are not limited to high cost, low efficiency, complex structure, slow speed, and lack of effective monitoring and automated cleaning mechanisms. These problems directly affect production efficiency and product quality, and impose an economic burden on manufacturers. A new technical solution is urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the above-mentioned background technology and provide a multi-stage filtration and flavoring and feeding pipeline system, which is characterized by including first-stage filtration, second-stage filtration, first-stage cleaning, second-stage cleaning, third-stage cleaning, pipeline monitoring, feeding three-stage cleaning control system, actuator, constant temperature water heater, popularization and monitoring of pneumatic valves, and operation screen control.

[0005] The specific operation modes are as follows:

[0006] (1) The first stage of filtration is to filter the liquid material before it enters the tank;

[0007] (2) The second stage of filtration is carried out before the liquid flows through the flow meter;

[0008] (3) The first level of cleaning focuses on cleaning the liquid filter. The pipes between the tank and the filter, as well as the filter itself, are cleaned using 70°C constant temperature hot water. The cleaned wastewater is directly discharged into the sewer.

[0009] (4) The second stage cleaning mainly cleans the flow meter, also using constant temperature hot water to ensure that the residue in the flow meter is effectively removed;

[0010] (5) The third level of cleaning is to clean the return pipe, and clean the filter and flow meter again to ensure the cleanliness of the system;

[0011] (6) Pipeline monitoring: Install a transparent window on the pipeline to allow operators to effectively observe the working status of components such as pipelines and flow meters, as well as the cleaning effect, and promptly identify and handle problems;

[0012] (7) The three-stage cleaning control system for feeding materials controls multiple programs through PLC, including the control of the three-way ball valve before the filter, the control of the three-way ball valve after the flow meter, the control of the flow meter detection valve, and the detection and judgment of the cleaning water flow;

[0013] (8) Actuators include valve island, gear pump, heating device, frequency converter, and pneumatic valve;

[0014] (9) The constant temperature water heater provides a constant flow of hot water at 70°C during the cleaning process;

[0015] (10) Popularization and monitoring of pneumatic valves There are a total of 23 pneumatic valves, each of which is equipped with a valve position feedback device to provide a signal to the PLC to ensure the accuracy of the valve position. The signal also allows the water flow of the second and third level cleaning to be detected;

[0016] (11) All operations are performed through the industrial computer operation screen, and the instructions are sent to the PLC and automatically completed by the control program;

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a multi-stage filtration flavoring and feeding pipeline system, which aims to solve the problems of pipeline blockage, difficult maintenance and high costs commonly encountered in the flavoring and feeding processes in the tobacco processing industry. By introducing advanced multi-stage filtration technology, automated cleaning procedures, and real-time monitoring mechanisms, this pipeline system significantly improves overall processing efficiency and reduces operating costs.

[0021] Overall structure of the piping system:

[0022] The piping system of the present invention utilizes pipes made of corrosion-resistant materials, including but not limited to stainless steel and food-grade plastic, ensuring chemical resistance and durability when transporting spices and additives. The entire system includes a feed pipe, a multi-stage filtration unit, flow control components, and automatic cleaning and monitoring devices.

[0023] Feeding pipeline design:

[0024] The feed line is the starting point of the system, designed to transport the raw materials to the first filtration unit. Its inner diameter and length are optimized to minimize pressure loss and flow resistance during the transfer process. A pre-filter, designed to filter out large particles, is located at the inlet of the line. It consists of a coarse mesh structure and is easy to disassemble and clean.

[0025] Multi-stage filtration unit:

[0026] The core of the system is the multi-stage filtration unit. Each filter unit is constructed from multiple layers of filter media, each of which is progressively finer to effectively capture particles of varying sizes. Pressure and flow sensors are located after each filter unit to monitor filtration efficiency and identify potential blockages. The filter units are designed for quick disassembly, without the need for tools, allowing for rapid replacement of filter media.

[0027] Flow control components:

[0028] The flow control components include precise electric control valves and flow meters, which work together to ensure accurate metering of the liquid during the flavoring and feeding process. The flow meter is a high-precision model to ensure the consistency of the formula. The control valve is designed to respond quickly to meet the needs of the rapid changes in the production process.

[0029] Automatic cleaning and monitoring device:

[0030] A key innovation of this system is its automated cleaning and monitoring mechanism. Using an integrated PLC and sensor network, the system automatically executes cleaning cycles, ensuring the filter and piping remain clean at all times. The cleaning cycle is automatically adjusted based on feedback from flow meters and pressure sensors. Furthermore, the system features an automatic drain valve to remove accumulated dirt during the cleaning process.

[0031] The system design takes into account various operating conditions, including temperature, pressure, chemical properties, etc., to ensure reliable operation in different working environments. Every part of the piping system is carefully calculated and tested to verify its performance and durability.

The system controls multiple programs through PLC (programmable logic controller), including the control of the three-way ball valve before the filter, the control of the three-way ball valve after the flow meter, the control of the flow meter detection valve, and the detection and judgment of the cleaning water flow. The detection devices mainly include valve position feedback device (for detecting valve position), pressure detection switch, and flow meter. The actuators include valve island, gear pump, heating device, frequency converter, pneumatic valve, and constant temperature water heater. A 70℃ water heater is set to provide constant flow of hot water during the cleaning process to improve the cleaning capacity and effect. The popularization and monitoring of pneumatic valves, a total of 23 pneumatic valves, are equipped with a valve position feedback device to provide signals to the PLC to ensure the accuracy of the valve position. These signals also allow the water flow of the second and third stage cleaning to be detected. The operation screen is controlled. All operations are performed through the industrial computer operation screen. The instructions are sent to the PLC and automatically completed by the control program.

[0037] Example 2: During the feed production process, the first stage of filtration is performed, that is, the feed liquid is initially filtered when it enters the feed tank. Subsequently, before the feed liquid flows through the flow meter, a second stage of fine filtration is performed to ensure that particulate matter is removed, thereby reducing pipeline blockage;

[0038] The first level of cleaning focuses on cleaning the liquid filter. 70°C constant temperature hot water is used to clean the pipes between the tank and the filter, as well as the filter itself. The cleaned wastewater is directly discharged into the sewer.

[0039] The second level of cleaning mainly cleans the flow meter, also using constant temperature hot water to ensure that the residue in the flow meter is effectively removed;

[0040] The third level of cleaning is to clean the return pipe, and clean the filter and flow meter again to ensure the cleanliness of the system;

[0041] Pipeline monitoring: transparent windows are installed on the pipelines to allow operators to effectively observe the working status of pipelines, flow meters and other components, as well as the cleaning effect, so as to identify problems and deal with them in time;

[0042] A three-stage cleaning control system for feeding was developed and designed. The system uses a PLC (Programmable Logic Controller) to control multiple programs, including the three-way ball valve control before the filter, the three-way ball valve control after the flow meter, the flow meter detection valve control, and the cleaning water flow detection and judgment;

[0043] The detection devices mainly include valve position feedback device (used to detect valve position), pressure detection switch and flow meter;

[0044] Actuators include valve island, gear pump, heating device, frequency converter, and pneumatic valve;

[0046] The popularization and monitoring of pneumatic valves, totaling 23 pneumatic valves, are equipped with valve position feedback devices on each valve to provide signals to the PLC to ensure the accuracy of valve position. These signals also allow the water flow of secondary and tertiary cleaning to be detected;

[0048] Example 3: The solution uses constant temperature hot water as a cleaning agent. Different types of cleaning agents can be considered and selected, such as specific cleaning solutions. These solutions may be more effective for certain types of residues. The energy consumption of the constant temperature water heater may be an aspect that needs to be optimized. A more efficient heat recovery system can be considered to reduce energy waste. The benefits of this embodiment are:

[0049] Improve production efficiency:

[0050] Through this cleaning process, problems such as material interruption and feed flow fluctuation caused by blockage in the production process have been significantly reduced, which directly improves the operating efficiency and stability of the production line and reduces production delays caused by equipment downtime;

[0051] Optimize product quality:

[0052] In traditional feeding systems, suspended particles in the feed liquid can cause fluctuations in product quality. The three-stage cleaning process effectively reduces the number of suspended particles in the product by improving cleaning efficiency and cleaning quality, thereby optimizing product quality.

[0053] Extend equipment service life:

[0054] Blockage is one of the key factors that lead to premature aging and damage of equipment. The implementation of this technical solution reduces wear and corrosion of equipment by keeping the piping system clean, thereby extending the service life of the equipment.
