[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] The gas volume regulating structure provided by the embodiment of the present invention is as follows: Figure 1 As shown, the coke oven regenerator body 1 and the small flue 2, the top of the small flue 2 and the coke oven regenerator body 1 are connected, including:

[0047] Brick base 3, such as Figure 2 As shown, the brick base 3 is installed on the top of the small flue 2, and the brick base 3 is provided with a through groove 31 (which can be understood as penetrating along the thickness of the brick base 3), and the through groove 31 connects the small flue 2 and the coke oven regenerator body 1; Figure 5 As shown, a windshield structure is provided in the through slot 31, and an air flow channel 32 is formed between the windshield structure and the peripheral wall of the through slot 31. The windshield structure is provided with a through hole 33 extending through the windshield structure along its axial direction.

[0048] Adjust brick 4, such as Figure 7 and Figure 8 As shown, the adjusting brick 4, the adjusting brick 4 can be partially rotatably installed in the through slot 31, and the horizontal cross-sectional area of ​​the adjusting brick 4 installed in the through slot 31 is smaller than the horizontal cross-sectional area of ​​the through slot 31; the adjusting brick 4 is provided with a mounting hole 41 on the side facing the windshield structure;

[0049] Adjustment rod 5, such as Figure 3 and Figure 4 As shown, the insertion end of the adjustment rod 5 passes through the bottom of the small flue 2, the middle of the small flue 2 (which can be understood as the hollow part of the small flue 2), and the through hole 32 in sequence, and is inserted and connected to the mounting hole 41, so that the adjustment brick 4 is adjusted to rotate relative to the windshield structure by the adjustment end of the adjustment rod 5 located outside the small flue 2 to change the flow cross-section of the airflow channel 32. It should be noted that a bottom through hole is formed at the bottom of the small flue 2, and the insertion end of the adjustment rod 5 passes through the bottom through hole, the middle of the small flue 2, and the through hole 32 in sequence, wherein the diameters of the bottom through hole and the through hole 32 are both larger than the diameter of the insertion end of the adjustment rod 5, so that the adjustment rod 5 can rotate relative to the bottom through hole and the through hole 32.

[0050] In the above technical solution, when in use, the operator manipulates the adjustment rod 5 below the bottom of the small flue 2 to rotate the adjustment rod 5. When the adjustment rod 5 rotates, the adjustment brick 4 fixed on the insertion end follows the adjustment rod 5 to perform synchronous rotation. During the rotation of the adjustment brick 4, the adjustment brick 4 blocks the flow cross-section of the airflow channel 32, thereby achieving precise adjustment of the gas volume. At the same time, the operation is simple for the operator, the process is time-consuming, labor costs are reduced, and work efficiency is improved. It should be noted that if the flow cross-section of the airflow channel 32 is blocked, the flow volume of the airflow is small, and if the flow cross-section of the airflow channel 32 is blocked, the flow volume of the airflow is large.

[0051] In the above technical solution, it should be noted that when the regenerator body 1 is in the heating period, air and gas enter the regenerator body 1 through the small flue 2. When the regenerator body 1 is in the exhaust period, the exhaust gas generated by combustion enters the small flue 2 from the regenerator body 1. Figure 1 The double arrows in the figure indicate the flow direction of air and gas.

[0052] In an optional technical solution, if Figure 7 and Figure 8 As shown, the adjusting brick 4 rotatably installed in the through groove 31 is the first part adjusting brick 42. The two ends of the first part adjusting brick 42 are respectively abutted against the peripheral wall of the through groove 31, and the contour shapes of the two ends of the first part adjusting brick 42 are adapted to the peripheral wall shape of the through groove 31, so that the first part adjusting brick 42 is smoother during the rotation process.

[0053] Optimize the above technical solutions, such as Figure 8 and Figure 9 As shown, the portion of the adjustment brick 4 disposed above the first adjustment brick 42 is the second adjustment brick 43. The maximum dimension of the second adjustment brick 43 is greater than the maximum dimension of the first adjustment brick 42 and greater than the diameter of the through slot 31. Specifically, the bottom surface of the portion of the second adjustment brick 43 that protrudes beyond the first adjustment brick 42 is in contact with the end surface of the brick base 3, so that the second adjustment brick 43 is raised relative to the upper end surface of the brick base 3, facilitating the subsequent replacement of the adjustment brick 4.

[0054] In an optional technical solution, if Figure 6 As shown, the through groove 31 is divided into an upper groove portion 311 and a lower groove portion 312 from top to bottom, and a windshield structure is provided in the lower groove portion 312. The first part of the adjustment brick 42 is installed in the upper groove portion 311, and the peripheral wall of the upper groove portion 311 has a limiting protrusion for limiting the rotation of the first part of the adjustment brick 42, and the axial projection of the limiting protrusion is staggered from the windshield block 34. The setting of the limiting protrusion is to limit the rotation angle of the first part of the adjustment brick 42, thereby limiting the flow cross-section of the airflow channel 32.

[0055] Optimize the above technical solutions, such as Figure 6 and Figure 9 As shown, the limiting protrusion includes: a first protrusion 313 and a second protrusion 314 provided on the peripheral wall of the upper groove portion 311 and arranged symmetrically, the side surface of the first protrusion 313 is used to abut against the side surface of the end of the first part adjustment brick 42, and the side surface of the second protrusion 314 is used to abut against the end of the first part adjustment brick 42; wherein, the first protrusion 313 and the second protrusion 314 are included in the limiting protrusion. Specifically, as Figure 8As shown, when the first adjustment brick 42 is in the starting position, the projection of the first adjustment brick 42 in the axial direction coincides with the windshield structure, the first side surface of the second end portion of the first adjustment brick 42 abuts the first side surface of the first protrusion 313, and the second side surface of the first end portion of the first adjustment brick 42 abuts the first side surface of the second protrusion 314. At this time, the flow cross-section of the airflow channel 32 is maximum N. When the first adjustment brick 42 is in the ending position, the first adjustment brick 42 is arranged at 90 degrees to the windshield structure in the axial direction, the first side surface of the first end portion of the first adjustment brick 42 abuts the second side surface of the first protrusion 313, and the second side surface of the first end portion of the first adjustment brick 42 abuts the second side surface of the second protrusion 314. At this time, the flow cross-section of the airflow channel 32 is minimum M. Therefore, the flow cross-section of the airflow channel 32 is adjusted to be between the maximum flow cross-section N and the minimum flow cross-section M.

[0056] Combine Figure 6 、 Figure 8 and Figure 9 It can be seen that the first protrusion 313 includes: a first protrusion 315, a second protrusion 316, a third protrusion 317 and a fourth protrusion 318 which are provided on the peripheral wall of the upper groove portion 311 and are arranged at intervals;

[0057] The central angle corresponding to the interval between the first protrusion 315 and the second protrusion 316 is a first angle, and the central angle corresponding to the interval between the third protrusion 317 and the fourth protrusion 318 is a second angle; wherein, the first protrusion 315 and the second protrusion 316 are included in the first protrusion portion 313, and the third protrusion 317 and the fourth protrusion 318 are included in the second protrusion portion 314.

[0058] The first angle is equal to the second angle, the first protrusion 315 and the third protrusion 317 are symmetrically arranged, which can be understood as the first protrusion 315 and the third protrusion 317 are arranged with the same diameter, and the second protrusion 316 and the fourth protrusion 318 are symmetrically arranged, which can be understood as the second protrusion 316 and the fourth protrusion 318 are arranged with the same diameter. In another embodiment, the first angle is not equal to the second angle.

[0059] The side of the first protrusion 315 facing away from the second protrusion 316 is used to abut against the first side of the first end of the first portion of the adjusting brick 42 to limit the first portion of the adjusting brick 42 from continuing to move in the clockwise direction. The side of the second protrusion 316 facing away from the first protrusion 315 is used to abut against the first side of the second end of the first portion of the adjusting brick 42 to limit the first portion of the adjusting brick 42 from continuing to move in the counterclockwise direction.

[0060] The side of the third protrusion 317 facing away from the fourth protrusion 318 is used to abut against the second side of the second end of the first part adjusting brick 42 to limit the first part adjusting brick 42 from continuing to move in the clockwise direction. The side of the fourth protrusion 318 facing away from the third protrusion 317 is used to abut against the second side of the first end of the first part adjusting brick 42 to limit the first part adjusting brick 42 from continuing to move in the counterclockwise direction.

[0061] In the above technical solution, it can also be understood that the first protrusion 315 and the third protrusion 317 jointly restrict the first part of the adjustment brick 42 from continuing to move in the clockwise direction, and the second protrusion 316 and the fourth protrusion 318 jointly restrict the first part of the adjustment brick 42 from continuing to move in the counterclockwise direction.

[0062] In an optional technical solution, if Figure 5 and Figure 7 As shown, the windshield structure is a windshield block 34, which is disposed within the through slot 31 and extends radially therefrom. The two ends of the windshield block 34 are respectively connected to the peripheral walls of the through slot 31, forming an airflow channel 32 between the windshield block 34 and the peripheral walls of the through slot 31. In this technical solution, it can be understood that the two ends of the windshield block 34 are respectively connected to the symmetrical peripheral walls of the through slot 31, and the geometric center of the windshield block 34 coincides with the groove center of the through slot 31, so that the two sides of the windshield block 34 and the corresponding peripheral walls of the through slot 31 form an airflow channel 32.

[0063] The above technical solution is optimized, and the windshield block 34 and the through slot 31 are an integrally formed structure, so that the structure of the regulating brick 4 is stable and more durable.

[0064] In an optional technical solution, if Figure 12 As shown, the adjusting end of the adjusting rod 5 is fixedly sleeved with a dial 6. In the present technical solution, specifically, the dial 6 and the adjusting rod 5 are connected by welding to form a whole. The rotation angle is determined by the ground reference line, thereby determining the flow cross-sectional area of ​​the air flow channel 32 and adjusting the air volume. The ground reference line can be that when the adjusting rod 5 starts to rotate, the projection of the zero scale line of the dial 6 in the vertical direction coincides with the ground reference line. After the adjusting rod 5 drives the dial 6 to rotate, the rotation angle of the adjusting rod 5 is determined by the projection of a certain scale line of the dial 6 in the vertical direction coincides with the ground reference line. In another embodiment, the gas volume adjustment structure includes: a bearing and a dial 6, the inner circumferential wall of the inner ring of the bearing is sleeved on the outer circumferential wall of the adjustment end, and the outer circumferential wall of the outer ring of the bearing is sleeved with the dial 6, and a supporting structure is added to the ground, and bolts or clamps are set on the supporting structure to fix the dial 6. In this way, it can be ensured that when the adjusting rod 5 rotates, the dial 6 does not rotate with the adjusting rod 5, and then the rotation amount of the adjusting brick 4 is determined by the rotation angle of the adjusting rod 5.

[0065] In an optional technical solution, if Figure 10 and Figure 11 As shown, a hexagonal nut 7 is sleeved on the insertion end of the adjusting rod 5. The mounting hole 41 is shaped and sized to fit the hexagonal nut 7. The hexagonal nut 7 is inserted into the hexagonal hole to connect the insertion end of the adjusting rod 5 with the mounting hole 41. In this solution, since the hexagonal nut 7 is an industrial product, it helps to reduce costs. The adjusting rod 5 can be made hollow as needed to facilitate adjustment and reduce costs.

[0066] In an optional technical solution, the regulating brick 4 is fan-shaped to ensure that the regulating brick 4 can rotate smoothly in the regulating brick base 3, and the air flow channel 32 is fan-shaped to ensure that the flow control changes linearly.

[0067] In an alternative technical solution, adjusting the regulating brick 4 via the regulating rod 5 can control the cross-sectional area of ​​the airflow channel according to different production stages of the coke oven, linearly adjusting the gas volume (lean gas flow and air flow) entering the coke oven, saving time and costs, improving longitudinal heating uniformity, and enhancing coke quality. Furthermore, the regulating rod 5 can be interlocked with the coke oven automatic control system as needed, making adjustment even more precise and efficient.

[0068] The present invention also provides a coke oven regenerator, comprising: the gas volume regulating structure as described above. Since this solution adopts the gas volume regulating structure as described above, it also has corresponding beneficial effects. For details, please refer to the previous description and will not be repeated here.

All possible feature combinations are technical contents explicitly described in this document. Any of the multiple sub-features included in the same statement can be applied independently and does not necessarily have to be applied in conjunction with the other sub-features.

[0071] Advantages in the technical solution:

[0072] 1. Compared with the traditional "take and replace" adjustment method of replacing the adjustment brick, you only need to insert the adjustment rod into the installation hole, turn the adjustment rod, and determine the rotation angle through the stainless steel dial at the bottom. There is no need to replace or remove the adjustment brick.
