Description

Technical Field

[0001] This utility model relates to the technical field of preparing fluorinated asphalt, and particularly to a reactor for preparing fluorinated asphalt. Background Technology

[0002] Fluorinated asphalt is a pale yellow to black material with excellent chemical stability, superior thermal stability, outstanding hydrophobicity and oleophobicity (liquid repellency), and good electrical insulation properties. These properties enable it to play a crucial role in several high-end technology fields. Currently, fluorinated asphalt has made a leap from laboratory research to industrial application, especially in the field of high-performance lithium-ion batteries, where it has become an important auxiliary material driving the commercialization of next-generation anode materials such as silicon-carbon. Meanwhile, in other industrial sectors, fluorinated asphalt, as a high-strength engineering material, provides innovative solutions to sealing, corrosion protection, and insulation challenges in extreme environments.

[0003] Currently, the preparation of fluorinated asphalt mainly employs batch reactors, tubular reactors, and microreactors. However, these reactors all have certain limitations in practical applications. Batch reactors suffer from problems such as uneven reaction, uneven fluorination degree, low heat transfer efficiency, limited production efficiency, unsatisfactory scale-up effect, poor product quality stability, and high safety risks, making it difficult to meet the efficiency, quality, and safety requirements for large-scale industrial production of fluorinated asphalt. While tubular reactors offer advantages such as high reaction efficiency, uniform product quality, and ease of scale-up, they also suffer from drawbacks for fluorinated asphalt systems, including easy material blockage of channels, insufficient heat transfer capacity, large pressure drop, high energy consumption, limited operational flexibility, and poor operational flexibility, which severely restrict their industrial application in fluorinated asphalt production. Microreactors, with their unique microstructure design, achieve high-precision control of the reaction process, significantly improving efficiency, safety, and operational flexibility. However, their small channel size makes them prone to blockage, difficult to clean, and costly to manufacture, which also greatly restricts their widespread application in the preparation of fluorinated asphalt. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention proposes a reactor for preparing fluorinated asphalt that can achieve uniform and efficient internal reaction through automatic oscillation.

[0005] The objective of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a reactor for preparing fluorinated asphalt includes a tubular reactor filled with a reactive gas. Several material troughs containing reactive materials are detachably installed inside the tubular reactor. The top of each material trough has a communication structure that connects to the tubular reactor. The bottom of the tubular reactor is also equipped with mutually cooperating pulleys and a slide rail. The slide rail is an arc-shaped slide rail, and the tubular reactor is oscillating within the range of the slide rail.

[0006] As an improvement to the above technical solution, the cross-section of the tubular reactor is semi-circular, and both ends of the tubular reactor are sealed by flanges.

[0007] As a further improvement to the above technical solution, the center of the arc-shaped slide rail is set to correspond to the center of the tubular reactor, and the cross-section of the arc-shaped slide rail is the arc segment corresponding to the 45° central angle.

[0008] As a further improvement to the above technical solution, the two ends of the arc-shaped slide rail are also provided with limiting structures, which are used to limit the sliding distance of the tubular reactor on the slide rail.

[0009] As a further improvement to the above technical solution, a rigid support is also provided on the inner wall of the tubular reactor, and the material trough is detachably mounted on the rigid support.

[0010] As a further improvement to the above technical solution, the tubular reactor is equipped with a driving structure that provides driving force for the tubular reactor to slide on the slide rail. The flanges at both ends of the tubular reactor are also provided with rotating shafts corresponding to the center position of the cross-section of the tubular reactor.

[0011] As a further improvement to the above technical solution, the driving structure is a cylinder disposed on the side of the tubular reactor, and the end of the cylinder rod corresponds to the side of the tubular reactor in the horizontal direction.

[0012] As a further improvement to the above technical solution, a pusher block is also provided at the end of the cylinder rod, and a contact block that contacts the pusher block is provided on the side of the tubular reactor.

[0013] As a further improvement to the above technical solution, the diameter of the tubular reactor is in the range of 10~DN100 and the length is 10~1000mm; the diameter of the material trough is 5~DN80 and the length is 5~800mm.

[0014] As a further improvement to the above technical solution, the tubular reactor is also provided with an air inlet, an air outlet, and a temperature measuring hole on its arc-shaped sidewall.

[0015] The beneficial effects of this utility model through the above technical solution are: 1. By employing a periodic oscillating motion with a 45° inclination angle corresponding to the arc length, effective fluidization of the reactants is achieved, ensuring thorough mixing and suspension of the gas and solid phases. This not only greatly enhances heat transfer efficiency and ensures the thermal stability of the reaction process, but also effectively improves the fluorination reaction rate and conversion rate, ultimately significantly increasing the yield of fluorinated asphalt. 2. The material tank is set inside a sealed tubular reactor, forming a dynamically sealed reaction chamber, which allows for a more complete gas-solid reaction while ensuring that the material does not splash or overflow.

[0024] Reference Figure 1A reactor for preparing fluorinated asphalt includes a tubular reactor 1 filled with reactive gas. The tubular reactor 1 has a semi-circular cross-section, and its two ends along its extension direction are the inlet and outlet, which are sealed by flanges 3, which can be opened and closed. In this embodiment, the tubular reactor body is made of SS316 or SS304 stainless steel, with a pipe diameter of 10~DN100 and a pipe length of 10~1000mm. This structure of the tubular reactor 1 facilitates the installation of the hopper inside, and its sealed state allows the material trough 2 to form a dynamically sealed reaction chamber inside the tubular reactor 1, ensuring a more complete gas-solid reaction during the dynamic reaction process without material splashing or overflowing. In this application, the extension direction of the inlet and outlet of the tubular reactor 1 is horizontal, and the direction of the semi-circular cross-section of the tubular reactor 1 is vertical.

[0025] Reference Figure 2 , Figure 3 The tubular reactor 1 is detachably equipped with several material tanks 2 containing reactants. The material tanks 2 have a similar structure to the tubular reactor 1, also being tubular structures. Additionally, a rigid support 11 is installed on the inner wall of the tubular reactor 1, and the material tanks 2 are detachably mounted on the rigid support 11. Before the reaction, the flange 3 at one end of the tubular reactor 1 is opened, allowing the material tanks 2 to be inserted into the tubular reactor 1. The top of the material tanks 2 has a communication structure connecting to the tubular reactor 1. After the material tanks 2 are inserted into the sealed tubular reactor 1, the reaction gas in the tubular reactor 1 can contact the reactants in the material tanks 2 through the communication structure at the top of the material tanks 2, thereby achieving the fluorination reaction of asphalt. In this embodiment, the diameter of the material tanks 2 is DN5~DN80, the length of the material tanks 2 is 5~800mm, and the length ratio of the tubular reactor 1 body to the material tank 2 is 5:4~2:1.

[0026] In addition, the tubular reactor 1 is provided with an air inlet 8, an air outlet 7, and a temperature measuring hole 9 on its arc-shaped sidewall. The air inlet 8 and the air outlet 7 are used for aeration and venting during the material reaction process, and the temperature measuring hole 9 is used to detect the temperature inside the tubular reactor 1 during the reaction process. In this embodiment, the air inlet 8 and the temperature measuring hole 9 are located on the side of the tubular reactor 1 close to its horizontal plane, and the air outlet 7 is located on the side of the tubular reactor 1 away from its horizontal plane.

[0027] Since both the tubular reactor 1 and the tubular feed trough 2 have arc-shaped edges, while this structure extends the reactor's capacity and prevents materials from getting stuck at corners, the gas in this structure tends to flow along the arc-shaped edges and is less likely to enter the feed trough 2 for reaction. Therefore, the bottom of the tubular reactor 1 is also equipped with a matching pulley 4 and a sliding rail 5. The sliding rail 5 is arc-shaped, and the tubular reactor 1 oscillates within the range of the sliding rail 5. The oscillating motion of the tubular reactor 1 via the sliding rail 5 and pulley 4 achieves effective fluidization of the reactants, ensuring thorough mixing and suspension of the gas and solid phases. This not only greatly enhances heat transfer efficiency and ensures the thermal stability of the reaction process but also effectively improves the fluorination reaction rate and conversion rate, ultimately significantly increasing the yield of fluorinated asphalt. In this embodiment, two sets of pulley 4 and sliding rail 5 assemblies are provided, symmetrically arranged at both ends of the tubular reactor 1.

[0028] When the tubular reactor 1 slides on the arc-shaped slide rail 5, it essentially rotates around the center of the arc-shaped slide rail 5. To ensure that the oscillation of the tubular reactor 1 is uniform and stable, the center of the arc-shaped slide rail 5 is set to correspond to the center of the tubular reactor 1, and the tangent of the arc-shaped slide rail 5 is an arc segment corresponding to a 45° central angle. The tubular reactor 1 oscillates periodically on the slide rail 5, with an oscillation angle of -45° to 45°, which ensures thorough mixing of materials, maintains a consistent reaction temperature, and prevents materials from splashing and overflowing.

[0029] In addition, the two ends of the arc-shaped slide rail 5 are provided with limiting structures 51. The limiting structures 51 are used to limit the sliding distance of the tubular reactor 1 on the slide rail 5, so as to avoid the phenomenon that the bottom pulley 4 of the tubular reactor 1 will disengage from the slide rail 5 due to excessive impact force.

[0030] The oscillation of the tubular reactor 1 on the slide rail 5 requires an oscillation force. The tubular reactor 1 is driven by a drive structure 6, which provides the driving force for the tubular reactor 1 to slide on the slide rail 5. The flanges 3 at both ends of the tubular reactor 1 are also equipped with rotating shafts corresponding to the center of the cross-section of the tubular reactor 1. The tubular reactor 1 is a long, elongated tubular structure with a semi-circular cross-section. Therefore, the driving force provided by the drive structure 6 causes the tubular reactor 1 to rotate around the axis formed by the center of its own cross-section, thus achieving the oscillation of the tubular reactor 1 on the slide rail 5.

[0031] Reference Figure 4In one embodiment of this utility model, the driving structure 6 is a cylinder disposed on the side of the tubular reactor 1, with the end of the cylinder rod corresponding horizontally to the side of the tubular reactor 1. To avoid excessive vibration and impact caused by direct rigid contact between the cylinder rod and the tubular reactor 1, a pusher block 61 is also provided at the end of the cylinder rod, and a contact block that contacts the pusher block 61 is provided on the side of the tubular reactor 1. When the cylinder rod extends, the pusher block 61 contacts the contact block, providing a pushing force to the contact block, thereby causing the tubular reactor 1 to rotate around its corresponding axis.

[0032] In other embodiments of this utility model, the rotating shafts provided on the flanges 3 at both ends of the tubular reactor 1 are connected to the motor through a reducer. The oscillation of the tubular reactor 1 on the guide rail can also be achieved by driving the rotating shafts through the motor.

[0033] In other embodiments of this utility model, the pulley 4 and slide rail 5 assembly at the bottom of the tubular reactor 1 can be set as one or more sets. One set of pulley 4 and slide rail 5 assembly can save consumables, while multiple sets of pulley 4 and slide rail 5 assembly can improve the stability of the tubular reactor 1 during the oscillation process.

[0034] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the technical scope of this utility model and based on its technical essence shall still fall within the scope of this utility model.
