Description

Technical Field

[0001] The utility model belongs to the technical field of coke oven carbonization chamber pressure regulation, and particularly relates to a pressure monotonic device for a coke oven carbonization chamber. Background Technique

[0002] Most of the existing pressure monotonic devices for coke oven carbonization chambers adopt a flap structure, that is, the ventilation cross-sectional area is changed through the movement of the flap, so as to adjust the ventilation volume of the raw gas generated during the coke oven coking process, so that when the gas generation volume is small at the end of coking, the pressure at the bottom of the carbonization chamber can be maintained at a slightly positive pressure state, avoiding the generation of negative pressure and inhaling air, resulting in unnecessary burning of coke. Most of the existing pressure monotonic devices with flap structures cannot achieve a sealing effect when no gas is generated at the end of coking, resulting in air being inhaled at the bottom of the carbonization chamber and causing coke burning. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a pressure monotonic device for a coke oven carbonization chamber. When the ventilation holes on the adjusting cylinder coincide with the exhaust holes on the inner cylinder driven by the adjusting part, the raw gas inside the carbonization chamber can be discharged in time to achieve no smoke during coal charging. By changing the overlapping area between the ventilation holes on the adjusting cylinder and the exhaust holes on the inner cylinder, the change of the ventilation area of the raw gas can be realized, and the pressure at the bottom of the carbonization chamber can be adjusted. When the exhaust holes are separated from the ventilation holes, the carbonization chamber will be sealed to prevent air from being inhaled at the bottom of the carbonization chamber and causing coke burning.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A pressure monotonic device for a coke oven carbonization chamber includes an inner cylinder, an adjusting cylinder, an outer cylinder, and an adjusting part. The inner cylinder, the adjusting cylinder, and the outer cylinder are arranged in sequence from inside to outside.

The rotation of the adjusting cylinder realizes the purpose of making the ventilation hole on the adjusting cylinder coincide with or separate from the exhaust pipe on the inner cylinder, thereby achieving the purpose of adjusting the pressure in the coke oven carbonization chamber.

[0009] Preferably, a connecting flange for facilitating connection with a pipeline is also installed at the top of the inner cylinder. The setting of the connecting flange facilitates the connection of this device, greatly improving the connection efficiency and connection quality between this device and the pipeline.

[0010] Preferably, it further includes a socket pipe, which is connected to the outer cylinder. The setting of the socket pipe facilitates connection with a pipeline, improving the connection efficiency and connection quality between this device and the external pipeline.

Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0031] As Figure 1 、 Figure 2 shown, a monotonic device for the pressure in the coke oven carbonization chamber includes an inner cylinder 2, an adjusting cylinder 6, an outer cylinder 1, and an adjusting member 4. The inner cylinder 2, the adjusting cylinder 6, and the outer cylinder 1 are arranged in sequence from inside to outside. The adjusting cylinder 6 is rotatably connected to the inner cylinder 2, and the outer cylinder 1 is fixedly installed on the inner cylinder 2. An exhaust hole 201 is opened on the inner cylinder 2, and a ventilation hole 601 is opened on the adjusting cylinder 6. The exhaust hole 201 cooperates with the ventilation hole 601. The adjusting member 4 is installed on the outer cylinder 1 and is connected to the adjusting cylinder 6.

[0032] In order to ensure the sealing effect of the device, a gasket can also be provided between the inner cylinder 2 and the adjusting cylinder 6.

[0033] As an optimized solution of this embodiment, in order to facilitate the adjustment of the pressure inside the carbonization chamber, as Figure 3 、 Figure 4 shown, both the exhaust hole 201 and the ventilation hole 601 are provided with two. The two exhaust holes 201 are symmetrically arranged on both sides of the inner cylinder 2, and the two ventilation holes 601 are symmetrically arranged on both sides of the adjusting cylinder 6. The exhaust hole 201 corresponds to the ventilation hole 601 one by one.

[0034] When the exhaust hole 201 coincides with the ventilation hole 601, the purpose of exhausting gas is achieved. When the exhaust hole 201 does not coincide with the ventilation hole 601, the purpose of sealing the pipeline is achieved. It can ensure timely exhaust when the gas production is large, and when the gas production is small, it can enter the fine adjustment section to accurately adjust the ventilation area to achieve precise control of the pressure in the carbonization chamber. It can also realize the function of adjusting the pressure of a single-hole carbonization chamber and the reliable cut-off and pressure maintenance function between the carbonization chamber and the gas pipe, ensuring the stability of the pressure at the bottom of the carbonization chamber.

[0035] As an optimized solution of this embodiment, in order to accurately control the pressure in the carbonization chamber, as Figure 3 shown, the exhaust hole 201 has a triangular front end and a rectangular rear end, and the ventilation hole 601 has the same rectangular structure as the rear end of the exhaust hole 201.

[0036] The triangular plus rectangular setting of the exhaust hole 201 in cooperation with the rectangular structure setting of the ventilation hole 601 facilitates the control of the exhaust volume of the whole process. When the exhaust volume is large in the early stage, the rectangular structure on the exhaust hole 201 can be connected to the ventilation hole 601. When the exhaust volume is small at the end of coking, the triangular structure on the exhaust hole 201 can be connected to the ventilation hole 601, so as to achieve the purpose of accurately controlling the pressure at the bottom of the carbonization chamber.

[0037] As an optimized solution of this embodiment, as Figure 4 shown, the adjusting member 4 includes a motor 402, a driving wheel 401, and a driven wheel 403. The motor 402 is fixedly installed on the outer cylinder 1, the driving wheel 401 is fixedly installed on the output shaft of the motor 402, the driven wheel 403 is fixedly installed on the top outer wall of the adjusting cylinder 6, and the driving wheel 401 meshes with the driven wheel 403.

[0038] The motor 402 drives the driving wheel 401 to rotate. The driving wheel 401 meshes with the driven wheel 403. The rotation of the driving wheel 401 drives the driven wheel 403 to rotate. The rotation of the driven wheel 403 drives the adjusting cylinder 6 to rotate, so as to achieve the purpose of making the ventilation hole 601 on the adjusting cylinder 6 coincide with or separate from the exhaust pipe on the inner cylinder 2, thereby achieving the purpose of adjusting the pressure of the coke oven carbonization chamber.

[0039] The rotation of the motor 402 driving the driving wheel 401 and the driven wheel 403 to rotate to rotate the adjusting cylinder 6 is only one rotation method, and other rotation methods can also be used instead.

[0041] The setting of the connecting flange 3 facilitates the connection of the device, greatly improving the connection efficiency and connection quality between the device and the pipeline.

[0042] As an optimized solution of this embodiment, as Figure 1 shown, it further includes a socket pipe 5, and the socket pipe 5 is connected to the outer cylinder 1.
