Description

Technical Field

[0001] The utility model relates to the technical field of coke oven collecting pipe equipment, in particular to a manual measuring tool for the pressure of a coke oven collecting pipe. Background Technique

[0002] During the negative-pressure coal charging production process of coke ovens in coking enterprises, the amount of coal dust in the raw gas in the collecting pipe increases, which easily blocks the pressure gauge head of the collecting pipe. Problems such as abnormal data often appear in the DCS display of the pressure of the coke oven collecting pipe. In order to ensure the accurate display of the collecting pipe pressure, avoid the long-term negative pressure inside the carbonization chamber caused by the abnormal display of the collecting pipe pressure, resulting in the leakage of the coke oven body, and also to prevent the risk of the riser pipe smoking or being washed open due to the high pressure of the collecting pipe, it is necessary to manually measure the pressure of the coke oven collecting pipe regularly.

[0003] In the early stage, when measuring the pressure of the collecting pipe of the coke oven, the method adopted was to directly open the manual cleaning hole of the collecting pipe and insert a thin pipe into the collecting pipe for measurement. During the measurement process, the operation was inconvenient, the sealing was not tight and air leakage caused inaccurate measurement, and a large amount of raw gas overflowed, polluting the environment. Therefore, a manual measuring tool for the pressure of the coke oven collecting pipe is provided to solve the above problems. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a manual measuring tool for the pressure of a coke oven gas collecting pipe, including a steel pipe 3. A connecting plate 2 is fixedly connected to the outside of the steel pipe 3. A manhole cover 1 for cleaning the gas collecting pipe is provided on one side of the connecting plate 2. A circular groove 8 is opened inside the manhole cover 1 for cleaning the gas collecting pipe. Fixed plates 7 are symmetrically fixedly connected inside the circular groove 8. Second sliding grooves 16 for cooperating with the fixed plates 7 are symmetrically opened inside the connecting plate 2. One end of the steel pipe 3 is fixedly connected to a thin pipe 18. One end of the thin pipe 18 away from the steel pipe 3 is fixedly connected to a pressure guiding hose 4. One end of the pressure guiding hose 4 is fixedly connected to a pressure gauge 5. The user manually pushes the manhole cover 1 for cleaning the gas collecting pipe into the inside of the manhole for cleaning the gas collecting pipe to seal it, preventing the escape of raw gas during the operation. One person can operate it alone, with simple operation and saving operation time. The pressure gauge 5 can detect the pressure of the gas collecting pipe through the pressure guiding hose 4 and the steel pipe 3, improving the practicability of the device.

[0022] Further, a moving block 15 is slidably connected inside the second sliding groove 16. A card block 14 is fixedly connected to the top of the moving block 15. Card slots 6 for cooperating with the card block 14 are equidistantly opened inside the fixed plate 7. When the moving block 15 drives the card block 14 to move out of the inside of the card slot 6, the manhole cover 1 for cleaning the gas collecting pipe can be pulled away from the connecting plate 2.

[0023] Further, a telescopic spring 10 is fixedly connected inside the second sliding groove 16. The telescopic spring 10 is fixedly connected to the moving block 15. Under the elastic force of the telescopic spring 10, the moving block 15 pushes the card block 14 into the inside of the card slot 6, enabling quick disassembly and installation of the manhole cover 1 for cleaning the gas collecting pipe.

[0024] Furthermore, a limiting groove 17 is formed inside the connecting plate 2, and a limiting block 12 is slidably connected inside the limiting groove 17. The limiting block 12 is fixedly connected to the moving block 15, which facilitates the limitation of the moving block 15 and prevents the moving block 15 from shifting during movement.

[0025] Furthermore, a first sliding groove 13 is formed inside the connecting plate 2, and a U-shaped pulling block 11 is slidably connected inside the first sliding groove 13. The U-shaped pulling block 11 is fixedly connected to the limiting block 12. By pulling the U-shaped pulling block 11 to move, the U-shaped pulling block 11 drives the moving block 15 to move through the limiting block 12.

[0026] Furthermore, a sealing gasket 9 is fixedly connected inside the connecting plate 2. When the connecting plate 2 is pushed into the circular groove 8, the sealing gasket 9 can be squeezed, with strong sealing performance, ensuring the accuracy of the measurement data.

[0027] During operation, the user manually pushes the gas collecting pipe cleaning hole cover 1 into the inside of the gas collecting pipe cleaning hole to seal it, preventing the escape of raw coal gas during the operation. One person can operate it alone, with simple operation, saving operation time. The pressure gauge 5 can detect the pressure of the gas collecting pipe through the pressure guiding hose 4 and the steel pipe 3. When the gas collecting pipe cleaning hole cover 1 needs to be disassembled and replaced after long-term use, pull the U-shaped pulling block 11 to move. The U-shaped pulling block 11 drives the moving block 15 to squeeze the telescopic spring 10 through the limiting block 12. The moving block 15 drives the clamping block 14 to move out of the clamping groove 6, and then the gas collecting pipe cleaning hole cover 1 can be pulled to separate from the connecting plate 2. After the replacement is completed, push the connecting plate 2 into the circular groove 8, so that the fixing plate 7 enters the second sliding groove 16. The moving block 15 pushes the clamping block 14 into the clamping groove 6 under the elastic force of the telescopic spring 10, enabling the quick disassembly and installation of the gas collecting pipe cleaning hole cover 1, with strong sealing performance, ensuring the accuracy of the measurement data, and improving the practicality of the device.
