Description

Technical Field

[0001] This utility model relates to the field of petroleum coke carbon dioxide reactivity determination technology, specifically to a sample support structure for a petroleum coke carbon dioxide reactivity determination instrument. Background Technology

[0002] The petroleum coke carbon dioxide reactivity analyzer is a specialized device used to evaluate the ability of petroleum coke to undergo a gasification reaction with carbon dioxide at a certain temperature. This analyzer has important applications in petroleum coke quality evaluation, industrial production (such as the performance analysis of anode materials in the electrolytic aluminum industry), and carbon material research. The petroleum coke carbon dioxide reactivity analyzer consists of a high-temperature reaction furnace, a gas supply system, a sample carrier, a quality monitoring unit, and a data acquisition system. The sample carrier is usually a high-temperature resistant crucible.

[0003] Existing high-temperature resistant crucibles have simple structures. When containing petroleum coke, a large amount of petroleum coke accumulates inside the high-temperature resistant crucible, resulting in uneven distribution of CO2 gas flow field, low heat transfer efficiency at the contact surface between the sample and the support device, and significant local temperature fluctuations, which affect the accuracy of reaction rate measurement. To address this, we propose a sample support structure for a petroleum coke carbon dioxide reactivity analyzer. Utility Model Content

[0004] The purpose of this invention is to provide a sample support structure for a petroleum coke carbon dioxide reactivity analyzer, in order to solve the problems mentioned in the background art, such as the simple structure of existing high-temperature resistant crucibles, the large accumulation of petroleum coke inside the crucible when it is filled, the uneven distribution of CO2 gas flow field, low heat transfer efficiency at the contact surface between the sample and the support device, significant local temperature fluctuations, and the impact on the accuracy of reaction rate measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample support structure for a petroleum coke carbon dioxide reactivity analyzer, comprising:

[0006] A first splicing frame has a first layered plate fixedly installed inside it. The upper surface of the first layered plate has multiple bearing grooves, and the interior of the first layered plate has first ventilation micro-holes. The upper surface of the first splicing frame has four splicing holes, and the lower surface of the first splicing frame has splicing posts corresponding to the splicing holes. A second splicing frame is installed below the first splicing frame, and a bottom splicing frame is installed below the second splicing frame. A splicing buckle is installed at the front end of the bottom splicing frame, and a second layered plate is fixedly installed inside the bottom splicing frame. A base plate is fixedly installed on the right side of the second layered plate, and the interior of the base plate has second ventilation micro-holes. Support legs are fixedly installed at the bottom of the bottom splicing frame.

[0007] In a preferred embodiment of the sample support structure for a petroleum coke carbon dioxide reactivity analyzer of this utility model, the included angle between the first layered plate and the first splicing frame is an obtuse angle, and the support grooves are uniformly distributed along the upper surface of the first layered plate.

[0008] As a preferred sample support structure of the petroleum coke carbon dioxide reactivity analyzer of this utility model, the first ventilation micropores are uniformly distributed along the interior of the first layered plate, and the first ventilation micropores have a frustum-shaped structure.

[0009] As a preferred sample-bearing structure for a petroleum coke carbon dioxide reactivity analyzer of this utility model, the shape and size of the splicing column match the shape and size of the splicing hole.

[0010] As a preferred sample-bearing structure of the petroleum coke carbon dioxide reactivity analyzer of this utility model, the bottom splicing frame is detachably connected to the second splicing frame through the splicing buckle, and the first splicing frame is detachably connected to the second splicing frame.

[0011] As a preferred sample-bearing structure of the petroleum coke carbon dioxide reactivity analyzer of this utility model, the base plate is fixedly connected to the bottom splicing frame, and the second ventilation micropores are evenly distributed along the interior of the base plate.

[0012] Compared with the prior art, this utility model provides a sample support structure for a petroleum coke carbon dioxide reactivity analyzer, which has the following beneficial effects:

[0013] 1. This utility model fixes an inclined layered plate inside the splicing frame and sets multiple bearing grooves on the layered plate.

[0021] Please see Figures 1-4 A sample support structure for a petroleum coke carbon dioxide reactivity analyzer includes a first splicing frame 1, a first layered plate 3 fixedly installed inside the first splicing frame 1, multiple support grooves 9 provided on the upper surface of the first layered plate 3, first ventilation micropores 8 opened inside the first layered plate 3, four splicing holes 2 opened on the upper surface of the first splicing frame 1, splicing columns 7 corresponding one-to-one with the splicing holes 2 fixedly installed on the lower surface of the first splicing frame 1, a second splicing frame 5 installed below the first splicing frame 1, a bottom splicing frame 4 installed below the second splicing frame 5, a splicing buckle 6 installed at the front end of the bottom splicing frame 4, a second layered plate 13 fixedly installed inside the bottom splicing frame 4, a base plate 10 fixedly installed on the right side of the second layered plate 13, a second ventilation micropore 11 opened inside the base plate 10, and a support leg 12 fixedly installed below the bottom splicing frame 4.

[0022] In this implementation plan: by fixing an inclined layered plate inside the splicing frame, and setting multiple bearing grooves 9 on the layered plate, when petroleum coke is placed on the layered plate, each bearing groove 9 can bear a certain amount of petroleum coke, effectively avoiding the large accumulation of petroleum coke, so that carbon dioxide can be evenly contacted with petroleum coke, and improving the accuracy of reaction rate measurement.

[0023] Furthermore:

[0024] In an optional embodiment, the angle between the first layer plate 3 and the first splicing frame 1 is an obtuse angle, and the bearing groove 9 is uniformly distributed along the upper surface of the first layer plate 3.

[0025] In this implementation scheme: the inclined first layer plate 3 makes the bearing tank 9 not on the same horizontal plane, which facilitates the flow of the sample on the upper bearing tank 9 to the lower bearing tank 9.

[0026] Furthermore:

[0027] In an optional embodiment, the first ventilation micropores 8 are uniformly distributed along the interior of the first layered plate 3, and the first ventilation micropores 8 have a frustum-shaped structure.

[0028] In this embodiment, the frustum-shaped first ventilation micropore 8 facilitates the entry of carbon dioxide into the interior of the first ventilation micropore 8, thereby facilitating its blowing into the sample pile and contact with the sample.

[0029] Furthermore:

[0030] In an optional embodiment, the shape and size of the splicing post 7 match the shape and size of the splicing hole 2.

[0031] In this implementation plan: the two splicing frames are assembled together by splicing column 7 and splicing hole 2, making bottle filling between the splicing frames more convenient and stable.

[0032] Furthermore:

[0033] In an optional embodiment, the bottom splicing frame 4 is detachably connected to the second splicing frame 5 via splicing buckles 6, and the first splicing frame 1 and the second splicing frame 5 are detachably connected.

[0034] In this implementation plan, by setting up a detachable splicing frame, it is easy to disassemble the splicing frame for cleaning of the splicing frame and the layered board, and at the same time, it is easy to splice more splicing frames according to the amount of petroleum coke.

[0035] Furthermore:

[0036] In an optional embodiment, the base plate 10 is fixedly connected to the bottom splicing frame 4, and the second ventilation micropores 11 are evenly distributed along the interior of the base plate 10.

[0037] In this implementation scheme, a second ventilation micropore 11 is provided to facilitate the entry of carbon dioxide into the interior of the splicing frame and its contact with the sample.

[0038] Working principle: When using the sample support structure of this petroleum coke carbon dioxide reactivity analyzer, firstly, place the first splicing frame 1 above the second splicing frame 5, inserting the splicing post 7 below the first splicing frame 1 into the splicing hole 2 inside the second splicing frame 5. Then, splice the first splicing frame 1 and the second splicing frame 5 together using the splicing buckle 6 at the front end of the second splicing frame 5. Similarly, splice the bottom splicing frame 4 below the second splicing frame 5. Then, pour the petroleum coke into the interior of the first splicing frame 1. The petroleum coke here is screened petroleum coke, and the volume of the screened petroleum coke is larger than the volume of the first ventilation micropore 8 and the second ventilation micropore 11. The petroleum coke will enter the support tank 9. Once the support tank 9 is filled with a certain amount of petroleum coke, the excess petroleum coke will roll along the first layer plate 3. Moving to the next support tank 9, and so on, petroleum coke can be evenly spread on the first layer plate 3, the second layer plate 13, and the bottom plate 10. Then, the support structure consisting of the first splicing frame 1, the bottom splicing frame 4, and the second splicing frame 5 is placed into the high-temperature reactor inside the petroleum coke carbon dioxide reactivity analyzer for carbon dioxide reactivity determination. The support leg 12 supports the bottom splicing frame 4, facilitating carbon dioxide to enter the petroleum coke pile from the ventilation micropores inside the bottom plate 10, the second layer plate 13, and the first layer plate 3 and react evenly with the petroleum coke. The splicing frame and the layer plates are made of ceramic or graphite materials, and the splicing buckle 6 is also made of high-temperature resistant metal materials. This is the working principle of the sample support structure of the petroleum coke carbon dioxide reactivity analyzer.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
