[0024] This application provides an iron box for testing the thermal reactivity of coke, such as... Figure 1 As shown. The iron box for the coke thermal reactivity test includes a container cylinder 100, a bottom plate 200, and a cover plate 300.
[0025] The sidewall of the receiving cylinder 100 is provided with a plurality of vent hole groups 110, and the receiving cylinder 100 is made of seamless steel pipe; wherein, the plurality of vent hole groups 110 are arranged in a circular array around the axis of the receiving cylinder 100, and each vent hole group 110 includes a plurality of vent holes 111 spaced apart along the height direction of the receiving cylinder 100. For example, Figure 1 The container cylinder 100 shown has four vent groups 110 on its side, and the four vent groups are arranged in a circular array around the axis of the container cylinder 100; each vent group 110 includes three vent holes 111, and the three vent holes 111 are spaced apart along the height direction of the container cylinder 100.
[0026] The base plate 200 is fixedly connected to the bottom opening of the receiving cylinder 100. Specifically, the base plate 200 and the bottom opening of the receiving cylinder 100 can be connected by welding.
[0027] The cover plate 300 is detachably connected to the top opening of the receiving cylinder 100. That is, the cover plate 300 can be detached from the top opening of the receiving cylinder 100 or connected to the top opening of the receiving cylinder 100.
[0028] When conducting coke thermal reactivity tests using this iron box for coke thermal reactivity testing, coke is placed in the container 100, then a cover plate 300 is connected to the top opening of the container 100, and finally the iron box for coke thermal reactivity testing is placed in the reactor. Multiple vent groups 110 on the side wall of the container 100 allow air to enter the container 100, causing the coke to undergo a thermal reaction under the heating of the reactor. Specifically, because the multiple vent groups 110 are arranged in a circular array around the axis of the container 100, air can enter the container 100 from multiple directions; and because each vent group 110 includes multiple vent holes 111 spaced apart along the height direction of the container 100, coke at different heights within the container 100 can all have sufficient contact with the air.
[0029] When manufacturing the iron box for the coke thermal reactivity test, a section of seamless steel pipe is cut as the receiving cylinder 100, and multiple ventilation holes 110 are made on the cut seamless steel pipe. Then, the base plate 200 is fixedly connected to the bottom opening of the receiving cylinder 100. No bending process is required, making the manufacturing process simpler and significantly reducing manufacturing costs. Furthermore, because the receiving cylinder 100 is made of seamless steel pipe, it can withstand high temperatures, allowing the iron box for the coke thermal reactivity test to be used multiple times, reducing usage costs.
[0030] In some embodiments of this application, reference is made to Figure 2 and Figure 3 The iron box for testing the thermal reactivity of coke also includes a sleeve 600 and at least one annular guide rail 400, 500. At least one annular guide rail 400, 500 is disposed on the outer side of the receiving cylinder 100. The sleeve 600 is coaxially disposed on the outer side of the receiving cylinder 100 and slidably connected to the annular guide rail 400, 500, and the side wall of the sleeve 600 has multiple elongated holes 610 corresponding one-to-one with the multiple ventilation hole groups 110.
[0031] For example, Figure 2 and Figure 3 The outer side of the container cylinder 100 of the iron box used for the thermal reactivity test of coke is provided with four ventilation hole groups 110, and the side wall of the sleeve 600 is provided with four elongated holes 610, with each of the four elongated holes 610 corresponding to one of the four ventilation hole groups 110.
[0032] When the sleeve 600 slides within the annular guide rails 400 and 500, it rotates around its own axis, changing the relative position of the elongated hole 610 and the vent assembly 110, allowing the vent 111 to be partially covered by the sleeve 600. Furthermore, the operator can adjust the air intake per unit time of the receiving cylinder 100 by adjusting the area covered by the vent 111.
[0033] like Figure 2As shown, each vent group 110 is completely located within the corresponding elongated hole 610, and each vent 111 is fully open. At this time, the air intake of the receiving cylinder 100 per unit time is maximized. Figure 3 As shown, each vent 111 is partially covered by the sleeve 600, at which point the air intake of the receiving cylinder 100 per unit time is less than Figure 2 The state shown.
[0034] For example, the sleeve 600 is made of seamless steel pipe. When manufacturing the sleeve 600, a section of seamless steel pipe is cut, and a plurality of elongated holes 610 corresponding one-to-one with the plurality of vent hole groups 110 are opened on the cut seamless steel pipe.
[0035] Reference Figures 2 to 4 The aforementioned at least one annular guide rail 400, 500 includes a first annular guide rail 400 and a second annular guide rail 500. The first annular guide rail 400 and the second annular guide rail 500 are disposed on the outer surface of the receiving cylinder 100; specifically, the first annular guide rail 400 is welded to the outer surface of the receiving cylinder 100, and the second annular guide rail 500 is welded to the outer surface of the receiving cylinder 100. Furthermore, the first annular guide rail 400 is located above the plurality of vent hole groups 110, and the second annular guide rail 500 is located below the plurality of vent hole groups 110.
[0036] The top of the sleeve 600 is slidably connected to the first annular guide rail 400, and the bottom of the sleeve 600 is slidably connected to the second annular guide rail 500. When the sleeve 600 rotates around its own axis, the top of the sleeve 600 slides within the first annular guide rail 400, and the bottom of the sleeve 600 slides within the second annular guide rail 500.
[0037] Specifically, such as Figure 4 As shown, the cross-sections of the first annular guide rail 400 and the second annular guide rail 500 are both L-shaped. The L-shaped first annular guide rail 400 and the L-shaped second annular guide rail 500 form annular grooves with the outer side of the receiving cylinder 100, and the top and bottom of the sleeve 600 are located in the two annular grooves respectively.
[0038] Furthermore, continue to refer to Figure 2 and Figure 3 The iron box for testing the thermal reactivity of coke also includes a handle 1000, which is connected to the outer side of the sleeve 600. When it is necessary to adjust the air intake per unit time of the receiving cylinder 100, the handle 1000 is pushed, causing the sleeve 600 to rotate around its own axis. The handle 1000 provides a point of force for rotating the sleeve 600, making it convenient for operators to rotate the sleeve 600.
[0039] In some embodiments of this application, reference is made to Figures 1 to 3The iron box for the coke thermal reactivity test also includes at least one first connecting lug 700, at least one second connecting lug 800, bolt 910 and nut 920.
[0040] At least one first connecting lug 700 is connected to the outer side of the top end of the receiving cylinder 100, and the first connecting lug 700 has a first through hole 710. A second connecting lug 800 is connected to the cover plate 300, corresponding one-to-one with the at least one first connecting lug 700, and at least one second connecting lug 800 has a second through hole 810. Specifically, the first connecting lug 700 is welded to the outer side of the top end of the receiving cylinder 100, and the second connecting lug 800 is welded to the cover plate 300. Bolts 910 and nuts 920 are used to connect the cover plate 300 and the receiving cylinder 100 through the first through hole 710 and the second through hole 810.
[0041] For example, two first connecting ears 700 are connected to the outer side of the top of the receiving tube 100, and two second connecting ears 800 are connected to the cover plate 300. The two second connecting ears 800 correspond one-to-one with the two first connecting ears 700.
[0042] When it is necessary to connect the cover plate 300 to the top opening of the receiving cylinder 100, pass the bolt 910 through the first through hole 710 on the first connecting lug 700 and the second through hole 810 on the second connecting lug 800, and then install the nut 920 on the bolt 910 and tighten it. When it is necessary to disconnect the cover plate 300 from the top opening of the receiving cylinder 100, remove the nut 920 from the bolt 910, and then remove the bolt 910 from the first through hole 710 on the first connecting lug 700 and the second through hole 810 on the second connecting lug 800.
[0043] The above structure enables a detachable connection between the cover plate 300 and the top opening of the receiving cylinder 100. Of course, the cover plate 300 and the receiving cylinder 100 can also be detachably connected through other specific structures. For example, the iron box for the coke thermal reactivity test also includes at least two latches, each consisting of a hook portion and a locking portion. The hook portion is fixedly connected to the cover plate 300, and the locking portion is connected to the outer side of the receiving cylinder 100. When it is necessary to connect the cover plate 300 to the top opening of the receiving cylinder 100, the hanging ring of the locking portion is connected to the hook portion, and the locking portion is locked. When it is necessary to disconnect the cover plate 300 from the top opening of the receiving cylinder 100, the locking portion is unlocked, and the hanging ring of the locking portion is removed from the hook portion.
