The coke stacking assembly 1 includes a first receiving plate 11, a second receiving plate 12 and a column 13; a plurality of second receiving plates 12 are provided and are placed in layers above the first receiving plate 11; the first receiving plate 11 and the second receiving plate 12 are connected by the column 13; a plurality of second receiving plates 12 are connected by the column 13. The first receiving plate 11 is rectangular in a top view, and the second receiving plate 12 is rectangular in a top view; the column 13 is fixedly connected to the inner corner of the first receiving plate 11 by bolts, and the column 13 is fixedly connected to the inner corner of the second receiving plate 12 by bolts.

[0031] Reference Figure 1 to Figure 4A feed port 00 is provided on the top of the furnace body 0, and an air inlet 01 and an exhaust port 02 are provided on both side walls of the furnace body 0. An inert gas (such as nitrogen, argon, etc.) is blown into the air inlet 01 through a fan; the air inlet 01 is placed in the lower middle part of the furnace body 0, and the exhaust port 02 is placed in the upper part of the furnace body 0. The exhaust port 02 is connected and communicated with the waste heat boiler through a pipeline. The waste heat boiler and the fan are conventional existing technical solutions in the industry, and the specific structure will not be described again. An inclined plate is provided at the position of the air inlet 01 to guide the falling path of the red coke fed through the feed port 00, so that the red coke is finally accumulated on the coke stacking assembly 1 of the accommodating chamber 03. Refer to Figure 4 , when there are three second receiving plates 12, they are second receiving plates a12a, second receiving plates b12b and second receiving plates c12c. Figure 1 to Figure 4 : The initial position of the driving assembly 2 is that the second receiving plate c12c is flush with the top of the accommodating chamber 03; after the red coke fills the upper surface of the second receiving plate c12c, the driving assembly 2 drives the coke stacking assembly 1 to move upward until the second receiving plate b12b is flush with the top of the accommodating chamber 03; after the red coke fills the upper surface of the second receiving plate b12b, the driving assembly 2 drives the coke stacking assembly 1 to move upward until the second receiving plate a12a is flush with the top of the accommodating chamber 03; after the red coke fills the upper surface of the second receiving plate a12a, the driving assembly 2 drives the coke stacking assembly 1 to move upward until the first receiving plate 11 is flush with the top of the accommodating chamber 03; after the red coke fills the upper surface of the first receiving plate 11, inert gas is blown into the air inlet 01, and the inert gas takes away the heat of the red coke on the coke stacking assembly 1 and is discharged through the exhaust port 02. The red coke is arranged in layers on the coke stacking assembly 1, which has a larger surface area than the traditional stacking centralized arrangement, and therefore has a faster heat exchange efficiency.

[0032] Reference Figure 1 to Figure 3 The driving assembly 2 includes a protective shell 21, a push rod 22 and a push plate 23; the push rod 22 includes a fixed end and a driving end, the fixed end is fixedly connected to the top of the inner cavity of the protective shell 21 (for example, fixedly connected by bolts), the driving end is connected to the push plate 23 (for example, fixedly connected by bolts), and the push plate 23 is connected to the coke stack assembly 1 (for example, fixedly connected by bolts); the push rod 22 is arranged longitudinally. The push rod 22 is an electric push rod 22, a pneumatic push rod 22, a hydraulic push rod 22 or a combination thereof (for example, an electro-hydraulic push rod 22). The push plate 23 is fixedly connected to the first receiving plate 11 (for example, fixedly connected by bolts); a reinforcing rib is provided on the bottom surface of the connection position between the push plate 23 and the first receiving plate 11, which is used to increase the structural strength of the utility model. The reinforcing rib is welded and fixed to the push plate 23, and the reinforcing rib is welded and fixed to the first receiving plate 11.

[0033] Reference Figure 1 to Figure 3The driving assembly 2 further includes a sliding structure, which is arranged at the side wall of the inner cavity of the protective shell 21; the sliding structure is connected to the push plate 23.

The sliding structure is used to play an auxiliary guiding role for the push plate 23.

[0034] The cross section of the slider 25 is C-shaped, and the cross section of the slide rail 24 is I-shaped; the slider 25 is buckled with the slide rail 24, so that the slider 25 can slide along the slide rail 24 while preventing the slider 25 from falling off.

[0035] Reference Figure 2-Figure 3 The side wall of the furnace body 0 is provided with a strip hole 04 for accommodating the push plate 23, and the push plate 23 is placed in the strip hole 04 and can move up and down.

[0036] Reference Figure 2-Figure 3 The driving assembly 2 further includes a baffle 26 capable of covering the strip hole 04, the baffle 26 is arranged longitudinally, and the baffle 26 is connected to the push plate 23. The baffle 26 is used to prevent the inert gas from flowing into the driving assembly 2. The baffle 26 is arranged in close contact with the outer wall of the furnace body 0.

[0037] Reference Figure 5 to Figure 7 The first receiving plate 11 has a W-shaped cross section, and the second receiving plate 12 has a W-shaped cross section, so as to be more conducive to receiving red coke. Figure 3 to Figure 7 A vent hole 121 is provided at the convex position in the middle of the second receiving plate 12, and the red coke is gathered in a ring shape on the upper surface of the second receiving plate 12; the inert gas flows through the vent hole 121, which can accelerate the heat exchange at the center of the red coke gathered in a ring shape, thereby improving the overall efficiency of the utility model.

After the red coke is cooled, the driving mechanism drives the coke stacking assembly 1 to move downward into the accommodating chamber 03, and the staff removes the cooled coke on the coke stacking assembly 1, and then closes the flip plate 05. The flip plate 05 is connected to the bottom plate of the furnace body 0 by a spring lock.

[0040] Filters are installed in the air inlet 01 and the exhaust port 02 respectively by bolts to prevent coke ash from entering the air inlet 01 and the exhaust port 02.

[0041] An opening is provided at the lower end of the protective shell 21, and a fan is fixedly installed at the opening position by bolts, so as to dissipate heat for the drive component 2 and ensure the normal operation of the utility model.

[0042] The furnace body 0, the coke stack assembly 1, the push plate 23 and the baffle 26 are made of alloy materials (such as nickel-chromium stainless steel with a melting point of 1400°C, nickel steel with a melting point of 1530°C, alloy cast iron with a melting point of 1400°C, etc.); the temperature of red coke is generally around 1000°C, which ensures the normal operation of the utility model.

[0043] The utility model has a simple structure and reliable functions. It utilizes a multi-layer structure of the coke stack assembly 1 to realize the layered centralized arrangement of the red coke. Compared with the traditional stacked centralized arrangement, it has a larger surface area and therefore has a higher heat exchange efficiency. The red coke is gathered in a ring shape on the upper surface of the second receiving plate 12. When the inert gas flows through the vent 121, it can accelerate the heat exchange at the center of the red coke, further improving the heat exchange efficiency of the utility model.
