Description

Technical Field

[0001] This invention relates to the field of tobacco processing equipment technology, and more specifically to a pressure-adjustable feeding device. Background Technology

[0002] In industries such as tobacco, chemicals, pharmaceuticals, food, and lithium battery electrode material preparation, it is often necessary to precisely and uniformly add liquid materials to feeders, mixers, or subsequent processes. Traditional feeding devices (such as gravity feeders or screw feeders) have the following main shortcomings, making it difficult to meet the high standards required by modern industry: Poor uniformity: For materials with poor flowability, the feeding process is prone to intermittent and uneven phenomena, which directly affects the quality of the final product.

[0003] Pressureless control: It is impossible to create a positive or negative pressure environment according to specific process requirements. Positive pressure can prevent external air (such as oxygen and moisture) from entering, avoiding material oxidation or moisture absorption; negative pressure can effectively remove gases or volatiles contained in the material and enable smooth, gas-resistance-free feeding into the negative pressure reaction vessel.

[0004] Limited functionality: The lack of integrated heating, cleaning and intelligent monitoring systems results in low automation, inconvenient cleaning and poor process controllability. Summary of the Invention

[0015] The beneficial technical effects of this invention are as follows: According to this disclosure, the adjustable air pressure feeding device drives the cylinder mechanism to rotate through the drive mechanism, and the internal stirring mechanism promotes the formation of a uniform material curtain, providing a stable carrier for liquid injection. The pressure regulation system flexibly adjusts the air pressure inside the cylinder through a vacuum pump and an air filling unit to meet the requirements of positive or negative pressure operation, effectively isolating external environmental interference and preventing material oxidation or moisture absorption.

Therefore, they should not be construed as limitations on this invention.

[0021] This application provides a pneumatically adjustable feeding device, such as... Figures 1-13As shown, the system includes a cylinder system 100, a pressure regulating system 200, a feeding and cleaning system 300, and a control system 400. The cylinder system 100 includes a cylinder mechanism 1 and a drive mechanism 2. The drive mechanism 2 drives the cylinder mechanism 1 to rotate. The cylinder mechanism 1 includes a rotating drum 11 and a stirring mechanism 19 disposed inside the rotating drum 11. The stirring mechanism 19 causes the material to form a material curtain during the rotation of the rotating drum 11. The pressure regulating system 200 is connected to the cylinder system 100 and includes a vacuum pump and an air filling unit for regulating the air pressure inside the cylinder mechanism 1. The feeding and cleaning system 300 is connected to the cylinder system 100 and is used for feeding and / or cleaning the cylinder mechanism 1. The feeding and cleaning system 300 also includes a feeding unit, which includes a liquid injection pipe 18 for spraying liquid onto the material curtain inside the rotating drum 11. The control system 400 receives sensor signals and controls the actions of each actuator.

[0022] The adjustable-pressure feeding device provided in this embodiment drives the cylinder mechanism 1 to rotate through the drive mechanism 2. The internal stirring mechanism 19 promotes the formation of a uniform material curtain, providing a stable carrier for liquid injection. The pressure regulation system 200 flexibly adjusts the internal air pressure of the cylinder through a vacuum pump and an air filling unit to meet the requirements of positive or negative pressure operation, effectively isolating external environmental interference and preventing material oxidation or moisture absorption. The feeding unit of the feeding and cleaning system 300 uses the liquid injection pipeline 18 to accurately spray the liquid onto the material curtain, ensuring that the liquid and material are fully mixed, significantly improving the uniformity of feeding. The control system 400 receives signals from various sensors in real time and automatically adjusts the actions of each actuator to achieve intelligent control of the entire process, reducing human operation errors. The overall device has a compact structure, high functional integration, and improves production efficiency and product quality stability.

[0023] In one possible implementation, such as Figure 4 and Figure 5 As shown, the cylinder mechanism 1 includes an inlet / outlet 12, an electric slip ring 14, an observation window 17, and a roller ring 13. The inlet / outlet 12 is disposed on the rotating cylinder 11. The electric slip ring 14 is connected to one end of the rotating cylinder 11 through a rotary joint 15. The electric slip ring 14 is disposed at the other end of the rotating cylinder 11 and is used to observe the situation inside the rotating cylinder 11 through the observation window 17. The roller ring 13 is disposed at both ends of the rotating cylinder 11 for sealing, so that a sealed environment is formed inside the rotating cylinder 11.

[0024] The cylinder mechanism 1 facilitates the loading and unloading of materials through the inlet and outlet ports 12. The cooperation between the electric slip ring 14 and the rotary joint 15 ensures the stability of the electrical connection when the drum 11 rotates, avoiding wire entanglement. The observation window 17 facilitates real-time monitoring of the material status inside the drum 11, improving operational safety. The roller ring 13 forms a reliable seal at both ends of the drum 11, effectively isolating the external environment and maintaining stable air pressure inside the drum, providing a guarantee for subsequent pressurization or vacuuming operations, and ensuring the airtightness and reliability of the material handling process.

[0025] Before manually closing the cover, the rotating drum 11 is first pressurized to create a negative pressure before the cover is tightened, which utilizes the pressure difference to achieve a more reliable seal. First, the vacuum pump is started to draw the rotating drum 11 into a negative pressure state, making the internal air pressure lower than the external atmospheric pressure. Under the action of negative pressure, the external atmospheric pressure will naturally press the cover tightly against the inlet and outlet 12 of the rotating drum 11, forming a tighter seal. The negative pressure-assisted sealing can further reduce gas leakage and ensure the stability of the positive or negative pressure environment.

[0026] In one possible implementation, such as Figure 4 and Figure 5 As shown, the cylinder mechanism 1 also includes a heating unit 16 and a temperature sensor. The heating unit 16 includes a heating sleeve or heating belt, which is disposed on the outer wall of the rotating cylinder 11. The temperature sensor is disposed inside the rotating cylinder 11 and is used to detect the temperature inside the rotating cylinder 11.

[0027] The cylinder mechanism 1 can uniformly heat the material inside the rotating drum 11 through the heating sleeve or heating belt set on the outer wall. The temperature sensor set inside the rotating drum 11 can monitor the internal temperature changes in real time and feed the signal back to the control system 400 to achieve precise temperature control. The two work together to ensure that the material is always in the optimal temperature state during the feeding process, thereby improving the mixing uniformity and process stability.

[0028] In one possible implementation, such as Figure 2 and Figure 13 As shown, the drive mechanism 2 includes a frame 21, a rotating mechanism 22, and a weighing sensor 23. The rotating mechanism 22 is mounted on the frame 21 and is used to support and drive the rotating drum 11 mechanism to rotate around its own axis. The weighing sensor 23 is mounted on the frame 21 and is used to weigh the material inside the rotating drum 11 mechanism.

[0029] The drive mechanism 2 is supported by the frame 21, and the rotating mechanism 22 drives the rotating drum 11 to rotate smoothly around its own axis, ensuring that the material forms a uniformly distributed material curtain inside the drum. The weighing sensor 23 monitors the weight change of the material inside the rotating drum 11 in real time, providing accurate weight feedback to the control system 400, which facilitates accurate metering and automatic control of the feeding process, effectively improving the uniformity of material mixing and production efficiency, while ensuring the stability and reliability of equipment operation.

[0030] In one possible implementation, such as Figure 6 As shown, the feeding unit also includes a constant flow pump and a pressure control valve. The constant flow pump is used to provide a stable output flow to the feeding unit, and the pressure control valve is located on the pipeline before the nozzle 181 of the liquid injection pipeline 18.

[0031] The feeding unit uses a constant flow pump to achieve stable output of liquid material, ensuring precise and controllable spray flow and avoiding flow fluctuations that could affect the uniformity of feeding. The pressure control valve is located on the pipeline before the nozzle 181, which can effectively regulate the pipeline pressure, prevent liquid material from dripping or spraying unevenly, and ensure that the nozzle 181 works under the optimal pressure, significantly improving the mixing effect of the liquid material and the material.

[0032] In one possible implementation, the feeding unit includes a single-media injection system or a dual-media injection system.

[0033] Among them, the single-media system is suitable for conventional liquid conveying and has a simple and reliable structure; the dual-media system, by introducing an auxiliary medium, can enhance the atomization effect of the liquid and improve its permeability and mixing uniformity in the material.

[0034] The feeding unit adopts a single-media injection system or a dual-media injection system design, which can flexibly select the injection mode according to specific process requirements, improving adaptability and meeting both basic feeding requirements and the processing needs of complex materials.

[0035] In one possible implementation, the feeding and cleaning system 300 further includes a cylinder cleaning unit and a pipeline cleaning unit. The cylinder cleaning unit is used to clean the inner wall of the rotating drum 11, and the pipeline cleaning unit is used to clean the liquid injection pipeline 18.

[0036] Among them, the cylinder cleaning unit of the feeding and cleaning system 300 can efficiently remove residual materials from the inner wall of the rotating drum 11 and avoid cross-contamination; the pipeline cleaning unit is specifically used to clean the liquid injection pipeline 18, thoroughly removing residual liquid in the pipeline to prevent blockage or deterioration. The cylinder cleaning unit and the pipeline cleaning unit ensure that the equipment can be cleaned quickly and thoroughly between batches, extending the service life of the equipment.

[0037] In one possible implementation, such as Figures 1-3 As shown, the vacuum pump is used to evacuate the cylinder mechanism 1, creating a negative pressure environment inside the cylinder mechanism 1; the gas filling unit is used to fill the cylinder mechanism 1 with inert gas, process gas or compressed air, creating a positive pressure environment inside the cylinder mechanism 1.

[0038] The pressure regulating system 200 uses a vacuum pump to evacuate the cylinder mechanism 1, forming a stable negative pressure environment. This effectively removes gases and volatiles from the material, while preventing external air from seeping in, ensuring that the material is processed in an oxygen-free environment and avoiding oxidation and deterioration.

[0039] The pressure regulation system 200 can fill the cylinder with inert gas, process gas or compressed air through the inflation unit to form a positive pressure environment, isolate external moisture and impurities, and provide controllable sealed conditions for special process requirements.

[0040] In one possible implementation, the pressure regulating system 200 further includes a gas pressure sensor for real-time detection of the gas pressure inside the cylinder mechanism 1.

[0041] Among them, the gas pressure sensor can monitor the changes in internal air pressure of the cylinder mechanism 1 in real time and feed the data back to the control system 400 to ensure that the positive or negative pressure environment is established quickly and stably, effectively avoiding the impact of air pressure fluctuations on material processing. The gas pressure sensor data provides real-time basis for process optimization, significantly improving the accuracy and response speed of air pressure control.

[0042] In one possible implementation, such as Figures 1-3 As shown, the control system 400 includes a programmable logic controller or an industrial computer, which can set, store and recall process recipes, and automatically control the entire process of vacuuming, gas filling, heating, rotation, feeding and cleaning, while realizing real-time recording and data tracking of all process parameters.

[0043] The control system 400 uses a programmable logic controller (PLC) or an industrial computer (IPC) as its core processor. It can set, store, and recall various process formulas, enabling one-click production switching. It can also automatically coordinate the entire process of vacuuming, gas filling, heating, rotation, feeding, and cleaning, ensuring precise connection between each link. At the same time, by collecting and recording key parameters such as temperature, pressure, and weight in real time, it forms a complete data traceability chain, providing strong support for process optimization and quality analysis, and significantly improving the level of production automation and process controllability.
