Description

Technical Field

[0001] The present application belongs to the field of asphalt carriers, and more specifically, to a carrier used in an asphalt oxidation process. Background Art

[0002] Hard carbon negative electrode materials for sodium ion batteries have the advantages of high cost-effectiveness, high abundance, and adjustable structure, and are extremely promising negative electrode materials for sodium ion batteries. The precursor materials for hard carbon negative electrode materials for sodium ion batteries are mainly divided into four types: biomass precursors, sugar precursors, synthetic resin precursors, and asphalt precursors. Among them, asphalt precursors have the advantages of low cost, high carbon content, and high carbon yield, and are considered to be a potential carbon source for synthetic carbon negative electrodes.

[0003] Pitch can be used to form nearly parallel carbon layers during heating to ensure high carbon yield and conductivity. However, direct pyrolysis of pitch forms a microstructure with small interlayer spacing and high orientation during the uncontrollable liquid phase carbonization process, resulting in poor rate performance of sodium ion batteries. By modifying the pitch molecules and weakening or destroying the interaction between aromatics, the graphitization of pitch can be interfered with and the transformation of the microstructure can be driven.

[0004] Oxidative crosslinking is one of the ways to modify asphalt. Oxidative crosslinking of asphalt in air or oxygen atmosphere does not require the use of additional additives and does not introduce additional impurities, which has better potential for industrial mass production. However, when asphalt is oxidized, the degree of oxidation will be uneven due to uneven heating and insufficient oxygen contact, which will affect the use of the material in subsequent processes and also lead to poor electrochemical performance of the hard carbon formed in the end. Utility Model Content

[0005] In view of the defects of the prior art, the present application provides a carrier for the asphalt oxidation process, aiming to solve the problem of uneven oxidation degree during the asphalt oxidation process.

[0006] The present application provides a carrier for an asphalt oxidation process, which specifically includes a carrier body and a heat conductor. The carrier body is provided with a bearing cavity for bearing asphalt particles to be oxidized, and the heat conductor is connected to the carrier body and partially extends into the bearing cavity.

[0007] Through the above technical scheme conceived by the present application, compared with the prior art, the present application places the asphalt particles to be oxidized in the bearing cavity, and the heat conductive part extends into the bearing cavity. Heat conduction is achieved through the heat conductive part to heat the internal asphalt particles, so that the asphalt particles in the bearing cavity of the carrier body are evenly heated, thereby improving the oxidation effect of the asphalt particles.

[0008] As a further preferred embodiment, the heat conducting member includes a plurality of plug-in members, and the carrier body is provided with a plurality of through holes for plugging the plug-in members.

[0009] By adopting the above technical solution, the connector is inserted into the through hole and enters the load-bearing cavity. There is an assembly structure between the connector and the carrier body. When taking out the material after oxidation, the carrier body and the heat-conducting component are separated to facilitate material taking out, thereby avoiding the presence of the heat-conducting component extending into the load-bearing cavity affecting the difficulty of taking out the material from the load-bearing cavity.

[0010] As a further preference, the heat conducting member further comprises a bottom plate, and the plurality of connectors are all arranged on the bottom plate.

[0011] By adopting the above technical solution, it is convenient to insert a plurality of connectors into the bearing cavity at the same time, thereby improving the installation efficiency. Meanwhile, the plurality of connectors are connected through the bottom plate, thereby improving the heat conduction.

[0012] As further preferred, the plug connector includes a blocking portion and a plug-in portion, the blocking portion is arranged on the bottom plate, and the plug-in portion is coaxially arranged at an end of the blocking portion away from the bottom plate.

[0013] By adopting the above technical solution, after the connector is inserted into the through hole, the blocking portion can block the through hole, and the connector extends into the bearing cavity to contact the asphalt particles, so as to heat the asphalt particles.

[0014] As a further preference, a cross-section of the plug-in portion gradually decreases in a direction away from the base plate.

[0015] By adopting the above technical solution, it is convenient to quickly and accurately insert the plug-in part into the through hole on the carrier body, thereby improving the installation efficiency.

[0016] As a further preference, the height of the blocking portion is not less than the thickness of the bottom of the carrier body.

[0017] By adopting the above technical solution, the top of the sealing part can enter the bearing cavity, thereby preventing asphalt particles from being present between the plug-in part and the through hole at the bottom of the carrier body, which would cause uneven heating of the asphalt particles.

[0018] As a further preference, the heat conducting element is an integrally formed structure.

[0019] By adopting the above technical solution, the overall structural strength of the heat conducting component is improved.

[0020] As a further preferred embodiment, an air inlet channel is provided inside the plug-in part, one end of the air inlet channel extends to the bottom of the base plate, and a plurality of air outlets connected to the air inlet channel are provided on the outer wall of the plug-in part, and air or oxygen can be injected into the bearing cavity through the air inlet channel and the air outlets.

[0021] By adopting the above technical solution, air or oxygen is injected into the air inlet channel, and oxygen enters the bearing cavity from each air outlet, so that the asphalt particles in the bearing cavity of the carrier body can be evenly contacted with oxygen and the uniformity of asphalt particle oxidation can be improved.

[0022] As a further preference, a filter membrane layer is provided at each of the air outlets.

[0023] The asphalt particles can be blocked by the filter membrane layer to prevent the asphalt particles from entering the air outlet and the air inlet channel from the bearing cavity.

[0024] As further preferred, the opening of the air outlet is arranged toward the bottom plate.

[0025] By adopting the above technical solution, the plug-in part is inserted into the bearing cavity, and the asphalt particles will not enter the air outlet, thus avoiding the blockage of the air outlet.

[0026] As a further preference, an opening communicating with the air inlet passage is formed on the top of the plug-in portion, and a blocking cover is detachably connected to the opening.

[0027] By adopting the above technical solution, when the asphalt particles are large, the sealing cover can be opened so that air or oxygen can be injected upward from the opening, and the asphalt particles will not fall from the opening, thereby further improving the oxidation uniformity of the asphalt particles.

[0028] In general, the above technical solutions conceived by this application have the following technical advantages compared with the prior art:

[0029] 1. The present application places asphalt particles to be oxidized in a bearing cavity, inserts the connector on the bottom plate into the through hole and extends into the bearing cavity, and heats the bottom plate and the connector to achieve heat conduction, thereby uniformly heating the asphalt particles inside the bearing cavity and improving the oxidation effect of the asphalt particles;

[0030] 2. By injecting air or oxygen into the air inlet passage, oxygen can enter the bearing cavity from each air outlet, so that the asphalt particles in the bearing cavity of the vehicle body can be evenly contacted with oxygen, thereby improving the uniformity of the oxidation of the asphalt particles.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The present application discloses a carrier used in an asphalt oxidation process.

[0039] Embodiment 1:

[0040] Reference Figure 1-3 A carrier used in an asphalt oxidation process includes a carrier body 1 and a heat conductor 4. A bearing cavity 11 is opened on the top of the carrier body 1. The asphalt particles to be oxidized are placed in the bearing cavity 11 during the oxidation process. The heat conductor 4 is connected to the carrier body 1 and partially extends into the bearing cavity 11. In this embodiment, the heat conductor 4 is connected to the bottom of the carrier body 1. In other implementations, the heat conductor 4 can be connected to the side wall of the carrier body 1. The heat conductor 4 and the carrier body 1 can be specifically connected by an assembled connection method such as a plug-in connection, a threaded connection, and a snap connection. When sampling after the oxidation is completed, the heat conductor 4 is first disassembled and removed, and the material in the bearing cavity 11 is more convenient to take out.

[0041] In this embodiment, the heat conductive member 4 includes a plurality of connectors 3. A plurality of through holes 12 for the connectors 3 to be plugged into are provided on the carrier body 1. The connectors 3 extend into the bearing cavity through the through holes 12. The heat conductive member 4 conducts heat to uniformly heat the asphalt particles. This embodiment adopts an assembled structure to facilitate the extraction of asphalt particles.

[0042] In other embodiments, the plug connector 3 may be fixedly connected to the inner wall of the bearing cavity 11 or the bottom of the bearing cavity 11 .

[0043] In order to improve the installation efficiency of the plug connector 3 , the heat conducting member 4 further includes a bottom plate 2 , and the plurality of plug connectors 3 are fixedly connected to the bottom plate 2 .

[0044] In order to prevent the asphalt particles in the bearing cavity 11 from falling out of the through hole 12, the connector 3 on the base plate 2 can be inserted into and block the through hole 12. The connectors 3 and the through holes 12 are the same in number and arranged in the same position. The connector 3 extends into the bearing cavity 11 and can be evenly arranged in the asphalt particles. By heating the base plate 2 and the connector 3, the base plate 2 and the connector 3 transfer heat to the asphalt particles in the bearing cavity 11, so that the asphalt particles in the bearing cavity 11 are evenly heated.

[0045] In this embodiment, the heat conducting component is an integrally formed structure, wherein the plug-in component 3 includes a sealing portion 31 and a plug-in portion 32, the sealing portion 31 is fixedly connected to the base plate 2, the plug-in portion 32 is coaxially fixedly connected to the top of the sealing portion 31, and the outer peripheral wall of the sealing portion 31 can be fitted with the inner peripheral wall of the through hole 12. It can be understood that the through hole 12 can be set to a variety of different shapes.

[0046] In a specific embodiment, the height of the blocking portion 31 is not less than the thickness of the bottom of the carrier body 1 , and the cross-section of the plug-in portion 32 gradually decreases in the direction away from the bottom plate 2 , so that the plug-in portion 32 can be easily inserted into the bearing cavity 11 from the through hole 12 .

[0047] In order to further improve the oxidation uniformity of the asphalt particles, an air inlet channel 321 is opened inside the plug-in part 32, and the bottom end of the air inlet channel 321 passes through the sealing part 31 and the bottom plate 2 and extends to the bottom of the bottom plate 2. The outer wall of the plug-in part 32 is opened with a plurality of air outlets 322 connected to the air inlet channel 321. Air or oxygen can be injected into the bearing cavity 11 through the air inlet channel 321 and the air outlets 322.

[0048] Furthermore, a filter membrane layer (not shown) can be provided at the gas outlet 322, and the filter membrane layer can allow gas to pass through while preventing asphalt particles from entering the gas outlet 322 and causing blockage. It can be understood that the filter membrane layer here can also be a filter screen or the like.

[0049] In a feasible embodiment, the opening of the air outlet 322 is arranged toward the bottom plate 2 , and when the plug-in portion 32 is inserted into the bearing cavity, asphalt particles will not enter the air outlet 322 , thereby avoiding clogging of the air outlet 322 .

[0050] In this embodiment, the top of the plug part 32 is also provided with an opening 323 connected to the air inlet channel 321. The setting of the opening 323 can appropriately reduce the air pressure difference between the air inlet channel 321 and the inside and outside of the bearing cavity 11, thereby preventing asphalt particles near the air outlet 322 from being blown away due to excessive air pressure difference. In this embodiment, the loading thickness of asphalt in the bearing cavity 11 can be controlled to prevent its thickness from being higher than the top of the plug part 32, thereby preventing asphalt particles from entering the inside of the air inlet channel 321 through the opening 323 to a certain extent.

[0051] Furthermore, the opening 323 is detachably connected with a blocking cover 324 , such as a threaded connection. When the asphalt particles are large, the blocking cover 324 can be opened so that air or oxygen can be injected upward from the opening 323 without the asphalt particles falling from the opening 323 .

[0052] Embodiment 2:

[0053] Reference Figure 4 The difference between this embodiment and embodiment 1 is that a threaded connection is adopted between the sealing portion 31 and the base plate 2. Specifically, a hollow first stud is fixedly connected to the bottom of the sealing portion 31, and a first thread groove threadedly connected to the first stud is provided on the base plate 2. A threaded connection is adopted between the plug-in portion 32 and the sealing portion 31. Specifically, a hollow second stud is fixedly connected to the bottom of the plug-in portion 32, and a second thread groove threadedly connected to the second stud is provided on the top of the sealing portion 31. This structure is adopted for connection, which facilitates the disassembly and installation of the sealing portion 31 and the plug-in portion 32. Suitable sealing portion 31 and plug-in portion 32 are selected to improve the use effect of the carrier in the oxidized asphalt process.
