Abstract
Description
Technical Field
[0001] This utility model relates to an integrated device for an environmentally friendly and energy-saving graphene rotary cutting mobile module production line, belonging to the field of graphene production equipment. Background Technology
[0002] Graphene, as a novel two-dimensional nanomaterial, has attracted widespread attention in fields such as energy storage, composite materials, and conductive coatings due to its excellent electrical, thermal, and mechanical properties. Among existing graphene preparation processes, liquid-phase exfoliation has become an important preparation route due to its simplicity, suitability for large-scale production, and relatively low cost.
[0003] In liquid-phase exfoliation, water or organic solvents are typically used as the dispersion medium, and graphite is exfoliated into single-layer or few-layer graphene through methods such as ultrasound and shearing. This method requires a large amount of dispersion liquid for industrial applications to ensure sufficient dispersion and exfoliation of the graphite.
[0004] However, the water utilization rate in existing processes is low. The water required for peeling and dispersion is mostly for single use, and some of the water evaporates during the recycling process, resulting in less and less water in the recycling system, and even internal drying and condensation, which can lead to system damage and other problems, hindering the long-term preparation and use of graphene. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an integrated device for an environmentally friendly and energy-saving graphene rotary cutting moving module production line.
[0006] Environmentally friendly and energy-saving graphene rotary cutting moving module production line integration device, including A mixing tank, with an inlet pump connected to the front of the mixing tank, is used for feeding process liquid; An electrostatic processor connected to the mixing tank, the electrostatic processor containing graphene polymer liquid; A first ring-flush separator connected to the electrostatic processor performs liquid-gas separation on the processed graphene polymer liquid; In this process, the liquid from the first ring-flush separator is diverted to the first rotary cutting device, and the gas is diverted to the condenser. The first rotary cutting device is connected to a second ring-flush separator, which further separates the graphene polymer liquid into liquid and gas. The liquid from the second ring-flush separator is diverted to the second rotary cutting device, and the gas is diverted to the condenser. The condenser condenses the pure water from the second rotary cutting device and returns it to the electrostatic processor.
[0007] This technical solution incorporates a first and second ring-flush separator in the liquid-phase exfoliation process, enabling effective liquid-gas separation of the graphene polymerization liquid. The water portion is then recycled, avoiding the problems of single-use water and low recovery rates in existing processes, thus significantly improving water recycling efficiency. After separation, the graphene polymerization liquid is further condensed and recovered via a condenser, achieving pure water recycling and preventing the gradual reduction of moisture within the recovery system due to evaporation loss, drying out, or even equipment damage. This ensures the stability of the production line during long-term continuous operation. This device, through multi-stage liquid-gas separation and condensation recovery technology, enables repeated use, reducing external water replenishment requirements and lowering energy consumption and water costs during production.
[0008] Preferably, a first stainless steel wastewater pump is provided between the electrostatic processor and the first ring-flush separator, and a second stainless steel wastewater pump is provided between the first rotary cutting device and the second ring-flush separator.
[0009] This technical solution enables stainless steel wastewater pumps to maintain continuous and stable flow output during long-term operation, reducing equipment idling or blockage caused by uneven liquid supply and ensuring stable operation of the entire production line. Stable liquid supply allows the rotary cutting equipment to operate continuously under ideal working conditions, ensuring uniform stress on graphene during dispersion and exfoliation, and improving the layer count control and quality consistency of the finished graphene product.
[0010] Furthermore, the first stainless steel sewage pump is connected to the first annular separator through the first inlet pipe, and the second stainless steel sewage pump is connected to the second annular separator through the second inlet pipe. The outlets of the first inlet pipe and the second inlet pipe are both located at the bottom of the first annular separator and the second annular separator.
[0011] Furthermore, the first and second annular separators include a separation tube body, with an input pipe at the bottom of the separation tube body. The input pipe is inclined, so that the outflowing liquid flows obliquely onto the inner wall of the separation tube body, forming an annular vortex, thereby performing liquid-gas separation.
[0012] This technical solution uses an inclined input pipe, allowing the liquid to enter the separator at an angle. This creates a circular vortex on the inner wall, significantly enhancing the separation of liquid and gas, resulting in higher efficiency compared to direct injection. By utilizing the inclined input pipe and the circulation principle, highly efficient liquid-gas separation is achieved without the need for additional complex separation units. The device structure is more compact, which is beneficial for the stable operation of continuous and modular production lines.
[0013] Preferably, the first annular separator is provided with a first liquid outlet pipe in the middle, and the first annular separator is connected to the first rotary cutting device through the first liquid outlet pipe. The first annular separator is provided with a first gas outlet pipe at the top, and the first annular separator is connected to the condenser through the first gas outlet pipe.
[0014] This technical solution, by separately configuring liquid outlet and gas outlet pipes in the first annular separator, allows the liquid and gas to be discharged separately along different channels after separation, achieving efficient liquid-gas separation and improving the separation effect. The first gas outlet pipe at the top allows the gas to be smoothly discharged and enter the condenser, which helps to improve the efficiency of gas condensation and recovery, reduce water evaporation loss in the graphene polymerization liquid, and further improve the water recycling rate.
[0015] Preferably, the second ring-flush separator is provided with a second liquid outlet pipe in the middle, and the second ring-flush separator is connected to the second rotary cutting device through the second liquid outlet pipe. The second ring-flush separator is provided with a second gas outlet pipe at the top, and the second ring-flush separator is connected to the condenser through the second gas outlet pipe.
[0016] This technical solution incorporates a second liquid outlet pipe in the middle of the second annular separator, enabling the liquid, after secondary separation, to be stably and rapidly transported to the second rotary cutting equipment, ensuring a continuous and uniform rotary cutting process. The second annular separator also features a rationally arranged liquid and gas outlet pipe layout, creating a clearly defined circulation path for the liquid and gas within the system, further improving the overall circulation efficiency and operational stability of the graphene production line.
[0017] Furthermore, pressure gauges and flow meters are installed on the first and second liquid outlet pipes.
[0018] This technical solution involves installing pressure gauges and flow meters on the first and second liquid outlet pipes, enabling real-time monitoring of pressure and flow within the pipes. This allows operators to monitor the liquid delivery status at any time. The pressure gauge and flow meter monitoring allows operators to adjust the pump speed or flow rate based on actual pressure conditions, ensuring a stable and suitable liquid supply to the rotary cutting equipment, thereby improving the graphene dispersion and exfoliation effect.
[0019] Preferably, the first ring-flush separator is provided with a first discharge pipe at the bottom, which is used to discharge the liquid inside the first ring-flush separator. The second ring-flush separator is provided with a second discharge pipe at the bottom, which is connected to the electrostatic processor and is used to discharge the liquid inside the second ring-flush separator.
[0020] This technical solution involves installing drain pipes at the bottom of both the first and second annular separators. This allows for the removal of deposited or retained liquid from the separators when needed, facilitating cleaning and maintenance and preventing long-term liquid retention from causing system contamination or performance degradation. Timely drainage of residual liquid at the bottom prevents abnormal internal pressure or backflow due to excessive liquid accumulation in the separators, reducing impact on downstream units such as stainless steel sewage pumps and rotary cutting equipment, and extending equipment lifespan.
[0021] Furthermore, the first discharge pipe is connected to a discharge pump, and the first annular separator is connected to the outside for drainage through the discharge pump.
[0022] With this technical solution, the first discharge pipe is connected to the discharge pump, which allows the liquid inside the first annular separator to be discharged quickly under the action of the pump, which is more efficient than the gravity discharge method.
[0023] Preferably, the second rotary cutting device is connected to the electrostatic processor via a return pipe.
[0024] This technical solution connects the second rotary cutting device to the electrostatic processor via a reflux pipe, allowing the process liquid after rotary cutting to flow back directly, forming a stable circulation path and avoiding excessive reliance on external water replenishment. This reflux structure enables multiple recycling of water in the graphene polymerization solution, significantly improving water utilization efficiency and reducing water consumption during production.
[0025] The beneficial effects of this invention are as follows: By incorporating a first and second ring-flush separator in the liquid-phase exfoliation process, effective liquid-gas separation of the graphene polymerization liquid can be achieved, allowing the liquid portion to be recycled. This avoids the problems of single-use water resources and low recovery rates in existing processes, significantly improving water recycling efficiency. After separation, the graphene polymerization liquid is further condensed and recovered through a condenser, achieving pure water recycling and preventing the gradual reduction of internal moisture, drying, or even equipment damage due to evaporation losses. This ensures the stability of the production line during long-term continuous operation. This device, through multi-stage liquid-gas separation and condensation recovery technology, enables the graphene polymerization liquid to be recycled repeatedly, reducing external water replenishment requirements and lowering energy consumption and water costs during production.
