[0002] In the production of prebaked anodes, the baking step is crucial, directly impacting the quality of the final product. However, effectively monitoring baking quality and identifying weak links has long been a key research focus. Accurate monitoring is crucial for improving the quality of the baking process.

[0003] The current monitoring method is to drill through the preheated anode after the preheated anode is baked. Figure 17 The sample column is then inspected for surface quality and physical and chemical indicators. This monitoring method, however, requires metal tools to remove samples after the prebaked anode is baked, which damages the original surface of the sample column and makes it impossible to truly characterize the baking conditions within the prebaked anode.

[0045] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below in conjunction with the drawings in the embodiments of this application. The described embodiments are only part of the embodiments of this application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work based on the embodiments of this application should fall within the scope of protection of this application.

[0046] Example 1

[0047] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an industrial roasting vessel for experimental prebaked anode sample columns includes a roasting tube 1 for accommodating the sample column 9. The roasting tube 1 is a cylindrical structure with an open lower end and an open upper end. A top plate 2 is provided at the upper end of the roasting tube 1 to seal the open end. The top plate 2 is detachably fixed to the roasting tube 1. The roasting tube 1 and the top plate 2 together form a cavity for accommodating the sample column 9.

[0048] like Figure 4 and Figure 8As shown, at least three groups of positioning posts 3 are arranged in the cavity around the sample column 9. Each group of positioning posts 3 includes several positioning posts 3, and the positioning posts 3 in the same group are arranged in the vertical direction. The outer ends of the positioning posts 3 (the ends facing away from the sample column 9 are the outer ends) are connected to the side walls of the roasting tube 1, and the inner ends of the positioning posts 3 (the ends facing the sample column 9 are the inner ends) can abut against the outer surface of the sample column 9, thereby limiting the freedom of movement of the sample column 9 in the horizontal plane and making the sample column 9 coaxial with the roasting tube 1.

[0049] As a specific implementation, three groups of positioning columns 3 are arranged around the sample column 9 in the cavity described in this embodiment. Each group of positioning columns 3 includes three positioning columns 3, and the three positioning columns 3 in the same group are evenly arranged in the vertical direction.

[0050] As a specific implementation, the projection of the positioning column 3 on the horizontal plane in this embodiment is in a radially extending state, that is, the vertical plane where the axis of the positioning column 3 is located passes through the axis of the roasting cylinder 1 .

[0051] As a specific implementation method, Figure 7 and Figure 9 As shown, in this embodiment, the upper end of the inner side surface of the roasting cylinder 1 is provided with a boss 111 extending inward, and a limiting column is provided above the boss 111 and radially penetrates the roasting cylinder 1. The top plate 2 is located between the boss 111 and the limiting column, and the boss 111 and the limiting column together limit the freedom of the top plate 2 to move axially along the roasting cylinder 1. Preferably, the distance between the axis of the limiting column and the upper side surface of the boss 111 is equal to the sum of the thickness of the top plate 2 and the radius of the limiting column.

[0052] As a specific embodiment, the limiting column described in this embodiment is a bolt assembly, including a bolt 41 and a nut 42 provided on the bolt 41. The roasting cylinder 1 is located between the head of the bolt 41 and the nut 42, which can prevent the bolt 41 from slipping off the roasting cylinder 1.

[0053] Compared with the traditional method of passing the sample column 9 through the prebaked anode, the industrial baking container for experimental prebaked anode sample columns provided in this application is compact in size and more flexible in loading into the furnace. In this way, diversified monitoring results can be obtained through different loading positions, thereby comprehensively evaluating the baking quality and the impact of the baking temperature field on the prebaked anode. It can also accurately monitor the weak points in the baking process of the prebaked anode, and thus, based on the monitoring results, the baking process can be optimized to improve the product quality of the prebaked anode.

[0054] Furthermore, an escape hole 112 communicating with the cavity is provided on the side wall of the roasting cylinder 1 .

[0055] As a specific implementation, a plurality of rows of escape holes 112 are evenly distributed along the circumferential direction on the side wall of the roasting cylinder 1 in this embodiment, and each row of escape holes 112 includes a plurality of escape holes 112 arranged along the vertical direction.

[0056] As a specific implementation, three rows of escape holes 112 are provided on the side wall of the roasting cylinder 1 in this embodiment, and are alternately arranged with the three groups of positioning columns 3 .

[0057] Furthermore, the cavity is filled with a filler 5, and the sample column 9 is located in the filler 5. That is, the filler 5 is filled between the bottom surface of the sample column 9 and the bottom surface of the cavity, between the side surface of the sample column 9 and the side wall of the cavity, and between the top surface of the sample column 9 and the top surface of the cavity.

[0058] As a specific implementation, the filler in this embodiment is coke particles with a size of 0.075-1 mm.

[0059] By providing the filler 5 and the escape holes 112 for allowing the escape of volatiles, the actual roasting environment and the roasting process of the carbon block can be simulated, thereby ensuring the accuracy of the results.

[0060] Further, if Figure 4 、 Figure 6 and Figure 8 As shown, the calcination cylinder 1 includes a main cylinder 11. A partition 12 is disposed at the lower end of the main cylinder 11. The partition 12 divides the interior of the main cylinder 11 into a calcination zone and a control zone, from top to bottom. The sample column 9 is located in the calcination zone. A bottom plate 13 is disposed within the main cylinder 11 below the partition 12.

[0061] As a specific implementation, the bottom plate 13 in this embodiment is fixedly connected to the main cylinder 11 in a detachable manner. Exemplarily, the bottom plate 13 is fixedly connected to the main cylinder 11 by a threaded connection.

[0062] A floating plate 61 is disposed within the control area of the main cylinder 11. An elastic member is disposed between the floating plate 61 and the roasting cylinder 1 to prevent the floating plate 61 from moving downward. In this embodiment, the elastic member is a spring 7 disposed between the floating plate 61 and the bottom plate 13. The upper end of the spring 7 abuts against the floating plate 61, while the lower end abuts against the bottom plate 13.

[0063] The floating plate 61 is provided with an upwardly extending top post 62, with the upper end of the top post 62 extending through the partition 12 to the upper portion thereof. The partition 12 is provided with a first through hole to provide a clearance for the top post 62. In this embodiment, the top post 62 is coaxially arranged with the roasting cylinder 1.

[0064] An upwardly extending tie rod 63 is provided at the edge of the floating plate 61. The upper end of the tie rod 63 extends through the partition 12 to the top of the partition 12. The partition 12 is provided with a second through hole to accommodate the tie rod 63. The number of tie rods 63 is the same as the number of groups of positioning posts 3, and there is a one-to-one correspondence between them, that is, there is a tie rod 63 below each group of positioning posts 3.

[0065] As a specific embodiment, in this embodiment, the diameter of the first through hole is the same as the diameter of the top column 62, and the diameter of the second through hole is the same as the diameter of the pull rod 63. The first through hole and the second through hole not only play a role in avoiding, but also cooperate with the top column 62 and the pull rod 63 to form a guiding function.

[0066] like Figure 5 、 Figure 9 and Figure 10 As shown, the outer end of the positioning column 3 is hinged to the ear plate 113 provided on the side wall of the roasting cylinder 1 through the hinge shaft 8. The positioning column 3 is provided with an avoidance groove 31 in the shape of an oblong hole that radially penetrates the positioning column 3, and the penetration direction of the avoidance groove 31 is perpendicular to the axis of the hinge shaft 8. The upper end of the pull rod 63 passes through the avoidance groove 31 of the corresponding group of positioning columns 3 in turn, and extends to the top of the uppermost positioning column 3. A limiting mechanism is provided between the positioning column 3 and the pull rod 63. Under the limiting action of the limiting mechanism, when the pull rod 63 moves up and down, it can drive the positioning column 3 to swing up and down around the hinge shaft 8.

[0067] As a specific implementation method, Figure 10 and Figure 11 As shown, the limiting mechanism in this embodiment includes a guide post 631 provided on the pull rod 63, and the positioning post 3 is provided with a guide groove 32 that cooperates with the guide post 631. The guide post 631 is fixedly connected to the pull rod 63 by a threaded connection.

[0068] Furthermore, the inner end of the positioning column 3 (the end facing the sample column 9 is the inner end) is a spherical structure.

[0069] The process of installing sample column 9 is as follows:

[0070] First, as Figure 12 As shown, filler 5 is added into the roasting zone of the roasting cylinder 1 , and the filler 5 cannot cover the upper end of the positioning column 3 .

[0071] Second, if Figure 13 As shown, a sample column 9 is loaded into the calcination area of the calcination cylinder 1 .

[0072] like Figure 13 and Figure 14 As shown, at this time, the pull rod 63 is at the upper limit position under the elastic support force of the spring 7. Accordingly, the positioning column 3 is also at the upper limit position of upward swing, and the distance between the inner end of the positioning column 3 and the axis is greater than the radius of the sample column 9. Therefore, the sample column 9 can be easily loaded into the roasting cylinder 1.

[0073] Third, if Figure 15 As shown, when the sample column 9 is fully inserted, its lower end abuts the top of the top post 62, and under the weight of the sample column 9, it pushes the top post 62 downward. The downward movement of the top post 62 drives the pull rod 63 downward via the floating plate 61, and the downward movement of the pull rod 63 drives the positioning post 3 downward until the inner end of the positioning post 3 abuts the side of the sample column 9. At this point, the sample column 9 is locked and centered, making it coaxial with the roasting cylinder 1 and securing the sample column 9.

[0074] Fourth, if Figure 16 As shown, filler 5 is added to the gap between the roasting cylinder 1 and the sample column 9 until the filler 5 is flush with the boss 111. During this process, the filler 5 in the roasting cylinder 1 needs to be compacted by repeatedly hitting the ground.

[0075] Fifth, cover the top plate 2 and tighten the bolt assembly to complete the loading of the experimental sample column 9.

[0076] Furthermore, the bottom plate 13 is provided with an operation hole 131 which passes through the bottom plate 13 in a vertical direction.

[0077] The reason for this design is that when one or more positioning columns 3 become stuck due to a malfunction, the floating plate 61 can be pushed through the operating hole 131 to cause the positioning columns 3 to swing upward and release the clamped sample column 9.

[0078] Furthermore, the operating hole 131 is a regular polygon. Thus, a rod or column that matches the shape of the operating hole 131 can be used as a tool to rotate the base plate 13, thereby achieving installation and removal of the base plate 13. As a specific embodiment, the operating hole 131 in this embodiment is a regular hexagonal structure.

[0079] Further, if Figure 6 As shown, an upwardly extending flange 132 is provided at the edge of the operating hole 131 , and the lower end of the spring 7 is sleeved on the outside of the flange 132 .

[0080] Example 2

[0081] The difference from the first embodiment is that the limiting mechanism is different. The limiting mechanism of this embodiment adopts the following structure:

[0082] The tie rod 63 is provided with limit rings on both the upper and lower sides of each positioning post 3, and the limit rings are fixedly connected to the tie rod 63 via set screws. The positioning post 3 is restrained within the two limit rings, and when the tie rod 63 moves up and down, it can drive the positioning post 3 to swing up and down.

[0083] The rest of the structure is the same as that of the first embodiment.

[0084] Other embodiments obtained by those skilled in the art by combining, splitting, reorganizing, etc. the embodiments provided in this application do not exceed the scope of protection of this application.

[0085] The above specific implementation methods provide a detailed description of the purpose, technical solutions and beneficial effects of the embodiments of the present application. The above is only a specific implementation method of the embodiments of the present application and is not intended to limit the scope of protection of the embodiments of the present application. That is, any modifications, equivalent replacements, improvements, etc. made on the basis of the embodiments of the present application should be included in the scope of protection of the embodiments of the present application.
