Technical Field

[0001] The utility model relates to the technical field of coke oven gas collecting systems, in particular to a carbonization chamber pressure regulating mechanism. Background Art

[0002] Pressure control in the carbonization chamber of a large coke oven is extremely important for the life of the coke oven, coke quality, pollutant emissions, and stable production operations. In the early stage of coal loading, the amount of raw gas produced is large, requiring sufficient outlet channels; in the late stage of coking, the amount of raw gas produced is small, and the raw gas outlet channel needs to be reduced to ensure the stability of the pressure in the carbonization chamber and avoid negative pressure and leakage. During the coking process, the amount of raw gas produced changes with time, and the raw gas outlet channel also needs to be adjusted accordingly during this process to ensure that the pressure in the carbonization chamber is relatively stable.

[0003] The existing carbonization chamber pressure regulating mechanism uses a cylinder and a drive cylinder as the driving power source for regulation. Its response speed is affected by the air source or the hydraulic system, and the response speed is relatively slow, resulting in a slow adjustment speed of the regulating mechanism, which increases the safety risk of the regulating mechanism.

[0006] Preferably, two groups of the fixing blocks are provided, and the screw rod rotates on the surface of the bridge tube through the fixing blocks.

[0007] Preferably, the nut is square in shape, and the nut slides on the surface of the bridge tube through the rotation of the screw rod.

[0008] Preferably, the fixing seat is connected to the interior of the bridge tube, and the piston rod slides on the bridge tube through the fixing seat.

[0009] Preferably, the connecting rod and the fixing seat are perpendicular to each other, and the piston rod drives the adjusting platform and the sealing ring to slide inside the bridge tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The output shaft of the motor drives the screw to rotate on the fixed block. During the rotation of the fixed block, the nut drives the nut to slide on the surface of the bridge tube. During the sliding process, the nut drives the adjusting rod to rotate. Since the adjusting rod has a certain length, during the rotation process, the piston rod is driven to slide and rise on the fixed seat through the connecting rod, thereby making the piston rod slide and rise on the bridge tube. During the lifting process of the piston rod, the adjusting table and the sealing ring are driven to rise and fall, thereby achieving the adjustment effect. During the adjustment process, the motor is used as the driving power. Since the motor responds faster, the adjustment speed is faster, which improves the safety of the adjustment mechanism.

[0014] 2. When the adjusting platform and the sealing ring drive the clamping ring to rise, the clamping ring will be inserted into the annular groove of the fixing ring. The clamping ring squeezes the rubber ring on the annular groove of the fixing ring, causing the rubber ring to deform. The rubber ring improves the sealing performance of the adjusting mechanism through deformation. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting mechanism can use the motor 6 as a driving power source, so that the adjusting platform 12 can be raised and lowered inside the bridge tube 2, and then the adjusting platform 12 can be adjusted and controlled inside the bridge tube 2, and when the adjusting mechanism is closed, the retaining ring 14 squeezes the rubber ring 16 on the fixing ring 15, so that the adjusting mechanism has better sealing performance, thereby improving the use effect of the adjusting mechanism.

[0024] Furthermore, two groups of fixing blocks 4 are provided, and the screw rod 5 rotates on the surface of the bridge tube 2 through the fixing blocks 4 , and the motor 6 drives the screw rod 5 to rotate on the bridge tube 2 through the output shaft.

[0025] Furthermore, the nut 7 is square in shape, and the nut 7 slides on the surface of the bridge tube 2 through the rotation of the screw rod 5. During the sliding process, the nut 7 drives the adjusting rod 8 to rotate on the nut 7, and the adjusting rod 8 causes the piston rod 11 to slide and rise and fall on the fixed seat 10 through the connecting rod 9.

[0026] Furthermore, the fixing seat 10 is connected to the interior of the bridge tube 2 , and the piston rod 11 slides on the bridge tube 2 through the fixing seat 10 , the top of the piston rod 11 slides above the bridge tube 2 , and the bottom of the piston rod 11 slides inside the bridge tube 2 .

[0027] Furthermore, the connecting rod 9 and the fixed seat 10 are perpendicular to each other, and the piston rod 11 drives the adjusting platform 12 and the sealing ring 13 to slide inside the bridge pipe 2.

During the rotation, the fixed block 4 drives the nut 7 to slide on the surface of the bridge tube 2. During the sliding, the nut 7 drives the adjusting rod 8 to rotate. Since the adjusting rod 8 has a certain length, during the rotation, the connecting rod 9 drives the piston rod 11 to slide and rise on the fixed seat 10, so that the piston rod 11 slides and rises on the bridge tube 2. During the lifting process, the piston rod 11 drives the adjusting platform 12 and the sealing ring 13 to rise and fall, thereby achieving the adjustment effect. When the adjusting mechanism needs to be closed, the adjusting platform 12 and the sealing ring 13 drive the retaining ring 14 to rise, so that the retaining ring 14 is inserted into the annular groove of the fixing ring 15. The retaining ring 14 squeezes the rubber ring 16 on the annular groove of the fixing ring 15, so that the rubber ring 16 is deformed.
