Description

Technical Field

[0001] This utility model belongs to the field of thermal regulation technology of coke oven heating system, specifically relating to an orifice plate for adjusting the air volume in the basement of a coke oven. Background Technology

[0002] Currently, the heating regulation method in the coke oven basement is still: adjustment by adding or subtracting calipers + large orifice plate + small orifice plate. Domestic research on automatic heating is also limited to automatically adjusting the addition or subtraction of calipers to control the gas intake and thus control the furnace temperature. For fine adjustment of the coke oven vertical flue, it can only be achieved by replacing the small orifice plate or applying pressure wire. Moreover, every time the coking time changes or tar blockage occurs, the small orifice plate must be disassembled, replaced, and cleaned to achieve the standard furnace temperature requirement. This has become a technical challenge to achieve intelligent and fine regulation. Therefore, there is a need for an orifice plate for adjusting the gas flow in the coke oven basement. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gas flow regulating orifice plate for use in the basement of a coke oven. This orifice plate can achieve precise adjustment of the vertical flue of the coke oven, and can be applied to the automatic heating system of the coke oven to realize automatic heating of the coke oven, reduce gas resistance, improve the high-level heating of the coke oven, increase the K-uniformity, K-safety, and K-head coefficients of the coke oven, save gas consumption, reduce the proportion of coke at the head of the oven, and has low modification cost, does not require disassembly and installation, can be adjusted online, and is easy to operate, thus solving the technical problems in the background art mentioned above.

[0004] The purpose of this utility model is achieved as follows: A gas flow regulating orifice plate applied in the basement of a coke oven includes a fixed orifice plate and an adjusting orifice plate. The fixed orifice plate is fixedly connected to a valve port of a valve body, and the adjusting orifice plate is disposed inside the valve body, corresponding to the fixed orifice plate. A transmission rod is disposed inside the valve body, one end of which is rotatably connected to the center position of the fixed orifice plate. The adjusting orifice plate is fixedly connected to the transmission rod. The surface of the fixed orifice plate has an external vent hole, and the surface of the adjusting orifice plate has an internal vent hole. In use, when it is necessary to adjust the gas intake, the transmission rod is rotated, which drives the adjusting orifice plate to rotate, causing the adjusting orifice plate to rotate relative to the fixed orifice plate, thereby causing the internal vent hole and the external vent hole to misalign. When the internal vent hole and the external vent hole are directly aligned, the gas flow is at its maximum. By utilizing the rotation of the internal vent hole to cause misalignment, the gas flow is gradually reduced. This allows for online adjustment of the gas flow without disassembly or installation, resulting in low modification costs and simple operation.

[0005] Furthermore, the external vent includes an outer hole and an outer second hole, both of which are fan-shaped holes; the internal vent includes an inner hole and an inner second hole, both of which are fan-shaped holes. The precise adjustment is achieved through the interplay of these fan-shaped holes.

[0006] Furthermore, a sealing nut is rotatably connected to the other end of the transmission rod, and the transmission rod extends partially outside the sealing nut. An adjusting knob is fixedly installed at the outer end of the transmission rod. One valve port of the valve body has an external thread, and the inner wall of the sealing nut has an internal thread, with the sealing nut and the valve port of the valve body forming a threaded seal. The adjusting knob is fan-shaped. In use, the operator rotates the adjusting knob to rotate the transmission rod, which in turn rotates the adjusting plate hole, causing the inner vent hole and the outer vent hole to be misaligned, thereby adjusting the gas intake.

[0007] The beneficial effects of this utility model are as follows: It solves the technical problem of needing to disassemble and replace the fixed orifice plate to regulate the gas intake of coke ovens. This utility model, without changing the original four-way design, adds a fixed orifice plate, an adjusting orifice plate, and a transmission rod inside to achieve fine regulation of the coke oven vertical flue. It is a novel orifice plate device with good gas sealing performance, online adjustment capability, simple operation, and ease of promotion. It features low modification cost and a safe, simple, and convenient structure. It can be applied to all coke oven types using underground heating and regulation processes, including tamping coke ovens, top-loading coke ovens, and their associated automatic coke oven heating systems.

Example 1

[0011] like Figure 1-3As shown, this embodiment discloses a gas flow regulating orifice plate used in the basement of a coke oven, including a fixed orifice plate 1 and an regulating orifice plate 2. The fixed orifice plate 1 is fixedly connected to a valve port of a valve body 3. The regulating orifice plate 2 is disposed inside the valve body 3 and is correspondingly disposed to the fixed orifice plate 1. A transmission rod 4 is disposed inside the valve body 3. One end of the transmission rod 4 is rotatably connected to the center position of the fixed orifice plate 1. The regulating orifice plate 2 is fixedly connected to the transmission rod 4. An external vent hole 5 is opened on the surface of the fixed orifice plate 1, and an internal vent hole 6 is opened on the surface of the regulating orifice plate 2. In use, when it is necessary to adjust the gas intake, the transmission rod 4 is rotated, which drives the regulating orifice plate 2 to rotate, causing the regulating orifice plate 2 to rotate relative to the fixed orifice plate 1, thereby causing the internal vent hole 6 to be misaligned with the external vent hole. When the inner vent 6 is aligned with the outer vent 5, the ventilation volume is at its maximum. By rotating the inner vent 6 to create misalignment, the ventilation volume is gradually reduced. This allows for online adjustment of the ventilation volume without disassembly or installation, resulting in low modification costs and simple operation. Example 2

An external vent hole 5 is opened on the surface of the fixed orifice plate 1, and an internal vent hole 6 is opened on the surface of the regulating orifice plate 2. In use, when it is necessary to adjust the gas intake, the transmission rod 4 is rotated, which drives the regulating orifice plate 2 to rotate, causing the regulating orifice plate 2 to rotate relative to the fixed orifice plate 1, thereby causing the internal vent hole 6 to be misaligned with the external vent hole. When the inner vent 6 is aligned with the outer vent 5, the ventilation volume is at its maximum. By rotating the inner vent 6 to create misalignment, the ventilation volume is gradually reduced. This allows for online adjustment of the ventilation volume without disassembly or installation, resulting in low modification costs and simple operation.

[0013] For better performance, the external vent 5 includes an outer hole and an outer second hole, both of which are fan-shaped holes; the internal vent 6 includes an inner hole and an inner second hole, both of which are fan-shaped holes. The interplay of these fan-shaped holes allows for precise adjustment.

An adjusting knob 8 is fixedly installed at the outer end of the transmission rod 4. One valve port of the valve body 3 is provided with an external thread 9, and the inner wall of the sealing nut 7 is provided with an internal thread. The sealing nut 7 is threadedly and sealed to one valve port of the valve body 3. The adjusting knob 8 is fan-shaped. In use, the operator rotates the adjusting knob 8 to rotate the transmission rod 4, which in turn rotates the adjusting plate hole, causing the inner vent 6 and the outer vent 5 to be misaligned, thereby adjusting the gas intake.
