[0002] The coke oven blower large circulation valve device is connected to the main pipe before the primary cooler via a process pipeline after the blower to balance the blower inlet pressure. Coal gas enters the coke oven blower large circulation valve device through the pipe, and then flows to the main pipe before the primary cooler through the pipe connected to the coke oven blower large circulation valve device.

[0003] In existing technologies, the gas pressure is controlled by adjusting the opening and closing angle of the large circulation valve of the coke oven blower, ensuring that the fluctuation of the gas collecting pipe does not exceed the normal value, thereby improving the stability of the pressure control of the carbonization chamber during the coking period of the PRoven system.

[0004] However, the inlet pipe of the traditional coke oven blower large circulation valve device is not equipped with a filter device, and impurities in the gas can easily enter the valve body, affecting the normal operation of the coke oven blower large circulation valve device. This makes it difficult to accurately regulate and control the gas pressure in the pipe, and it is difficult to ensure that the fluctuation of the gas collecting pipe does not exceed the normal value, resulting in poor stability. Therefore, this utility model proposes a coke oven blower large circulation valve device to solve the above problems. Utility Model Content

[0015] This invention proposes a large circulation valve device for a coke oven blower. After installation on designated equipment, the device ensures that the gas flows into the valve body through the front connecting pipe and flows out through the rear connecting pipe. The front and rear connecting pipes are short, variable-diameter pipes.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a coke oven blower large circulation valve device, the coke oven blower large circulation valve device includes: a rear connecting pipe 2, the rear connecting pipe 2 is connected to a valve body 1, the valve body 1 is connected to a front connecting pipe 3, a filter mechanism body 4 is provided on the front connecting pipe 3; the filter mechanism body 4 has an upper mounting groove 9, an installation mechanism 5 is installed on the filter mechanism body 4, the installation mechanism 5 is connected to a connecting plate 6, one end of the connecting plate 6 is stuck in the lower mounting groove 10, the connecting plate 6 is connected to a mounting frame 7, and a filter plate 8 is installed on the mounting frame 7;

[0026] In practical use, after installing the device on the designated equipment, ensure that the gas flows into the valve body 1 through the front connecting pipe 3 and flows out through the rear connecting pipe 2. The front connecting pipe 3 and the rear connecting pipe 2 are short pipes with different diameters. The valve body 1 is used for adjustment to achieve the purpose of balancing the pressure of the gas collecting pipe. The gas is filtered by the filter plate 8 on the mounting frame 7 set in the filter mechanism body 4 fixedly installed on the front connecting pipe 3, so as to prevent impurities and other pollutants in the gas from entering the valve body 1 and affecting its normal operation. This would make it difficult to make precise adjustment and achieve the purpose of balancing the pressure of the gas collecting pipe. Excessive fluctuations in the gas collecting pipe will lead to poor stability of the pressure setting value control of the carbonization chamber during the coking period of the PRoven system. This device improves stability.

[0027] Example 2

[0028] Based on Embodiment 1, a front connecting pipe 3 is provided to improve the performance of the device. The front connecting pipe 3 is fixedly installed on the valve body 1 by bolts and nuts. The other end of the valve body 1 is fixedly installed with a rear connecting pipe 2 by bolts and nuts. Both the front connecting pipe 3 and the rear connecting pipe 2 are short pipes with different diameters. After the device is installed on the designated equipment, it is ensured that the gas flows into the valve body 1 through the front connecting pipe 3 and flows out through the rear connecting pipe 2. Because the front connecting pipe 3 and the rear connecting pipe 2 are short pipes with different diameters, the pipes on the device have a change in diameter. The valve body 1 is used for adjustment to achieve the purpose of balancing and adjusting the pressure of the gas collecting pipe.

[0029] The filter plate 8 is fixedly installed on the mounting frame 7, which has a circular plate structure. The side of the mounting frame 7 contacts the inner wall of the filter mechanism body 4. The filter mechanism body 4 is fixedly installed on the front connecting pipe 3. The filter plate 8 on the mounting frame 7 inside the filter mechanism body 4 fixedly installed on the front connecting pipe 3 filters the gas, preventing impurities and other pollutants in the gas from entering the valve body 1 and affecting its normal operation. This makes it difficult to make precise adjustments and achieve the purpose of balancing the gas collecting pipe pressure. Excessive fluctuations in the gas collecting pipe can lead to poor stability of the pressure setting value control of the carbonization chamber during the coking period of the PRoven system, thus improving stability.

[0030] Example 3

[0031] Based on Embodiment 2, a filter mechanism body 4 is provided to improve the reliability of the device. A groove 16 is provided on the filter mechanism body 4. The groove 16 has a convex groove-shaped structure. A thrust spring 15 is provided inside the groove 16. One end of the thrust spring 15 is fixedly installed on the filter mechanism body 4, and the other end is fixedly installed on the slide plate 14. A baffle 17 is fixedly installed on the upper surface of the slide plate 14 by bolts. The baffle 17 has a square plate-shaped structure, as shown in the example. Figure 1 As shown, when the mounting mechanism 5 is installed on the filter mechanism body 4, the baffle 17 is just set on the slide 16. The baffle 17 covers the slide 16 to protect it and reduce the impact of dust and other impurities on the movement of the slide plate 14. The baffle 17 is detachable, so that personnel can maintain the thrust spring 15 in the slide 16.

[0032] The slide plate 14 has a convex plate-shaped structure. A stop block 12 is fixedly connected to the side of the slide plate 14. The stop block 12 has a trapezoidal plate-shaped structure. One end of the stop block 12 is inserted into a square groove 11 opened on the filter mechanism body 4. The stop block 12 can slide along the square groove 11. A sealing gasket 13 is fixedly connected to the stop block 12. The sealing gasket 13 has a square plate-shaped structure. When the mounting mechanism 5 is a combination of an "L"-shaped plate and a square plate, and when the mounting mechanism 5 is installed on the filter mechanism body 4, the position of the stop block 12 is as follows. Figure 3As shown, the side of the stop block 12 contacts the side of the mounting mechanism 5. By unscrewing and removing the bolts on the mounting mechanism 5, the operator can pull the mounting mechanism 5 upward, causing the lower end of the mounting mechanism 5 to press against the inclined surface of the stop block 12, so that the stop block 12 slides along the square groove 11, and the end of the stop block 12 that contacts the side of the mounting mechanism 5 is completely inserted into the square groove 11.

[0033] The mounting frame 7 is fixedly connected to the connecting plate 6. The upper surface of the connecting plate 6 is fixedly connected to the lower surface of the mounting mechanism 5. One end of the connecting plate 6 is stuck in the lower mounting groove 10. The lower mounting groove 10 has a square groove structure. The connecting plate 6 has a plate structure with a semi-circular groove on a square plate. This allows the connecting plate 6, the mounting frame 7, and the filter plate 8 to slide out along the lower mounting groove 10, so that personnel can clean the filter plate 8, ensure the filtration effect of the filter plate 8, and improve the reliability of the device.

[0034] The lower end of the mounting mechanism 5 is engaged in the upper mounting groove 9 opened on the filter mechanism body 4. The lower end of the mounting mechanism 5 can slide along the upper mounting groove 9. The upper mounting groove 9 has a square groove structure. The thrust spring 15 is always in a taut state. Then, the thrust spring 15 pushes the slide plate 14 to slide along the slide groove 16, causing the square groove 11 of the stop block 12 to slide, so that one end of the stop block 12 slides into the upper mounting groove 9. The stop block 12, together with the sealing gasket 13, seals the upper mounting groove 9 to prevent external impurities from entering the device and affecting the normal operation of the valve body 1. When the mounting mechanism 5 needs to be installed, the personnel can pull the baffle 17 to slide the stop block 12 out of the upper mounting groove 9, so that the upper mounting groove 9 is exposed, and the personnel can then install the mounting mechanism 5.

[0035] Working principle: In actual use, after the device is installed on the designated equipment, it ensures that the gas flows into the valve body 1 through the front connecting pipe 3 and flows out through the rear connecting pipe 2. The front connecting pipe 3 and the rear connecting pipe 2 are short pipes with different diameters. The gas is filtered by the filter plate 8 on the mounting frame 7 set in the filter mechanism body 4 fixedly installed on the front connecting pipe 3. This prevents impurities and other pollutants in the gas from entering the valve body 1 and affecting its normal operation. This makes it difficult to make precise adjustments and achieve the purpose of balancing the gas collecting pipe pressure. Excessive fluctuations in the gas collecting pipe will lead to poor stability of the pressure setting value control of the carbonization chamber during the coking period of the PRoven system. This device improves the stability during operation.
