Abstract
Description
Technical Field
[0001] This utility model belongs to the field of professional equipment modification of coal chemical gasification furnaces, specifically involving a sealing device for the ash discharge system of a solid slag discharge gasification furnace. Background Technology
[0002] Coal is conveyed to the coal bunker via a belt conveyor, then added to the coal chute via a coal lock, and enters the gasifier to participate in the pressurized gasification reaction to produce qualified syngas and natural gas. The solid ash produced after the coal reaction is discharged by the ash removal system. By sampling and observing the ash discharged from the ash removal system, the state of the ash can be used to guide the process medium parameter ratio of the gasifier, ensuring the safe and efficient operation of the pressurized coal gasification process. The ash removal system of the gasifier has sampling ports on the ash conveying pipe for sampling coal ash. For easy sampling, the sampling ports are inclined downwards at the bottom of the ash conveying pipe to ensure that the coal ash can easily slide off from the sampling port. When it is not necessary to observe the coal ash, the sampling ports need to be sealed. However, currently, the sampling ports of the gasifier ash removal system are sealed by a cover plate, which has poor sealing effect, resulting in serious ash leakage and gas leakage in the gasifier. Since the working environment of the gasifier is relatively complex, once a gas leakage occurs, it can easily lead to a safety accident. Utility Model Content

[0018] Currently, the sampling port of the gasifier ash discharge system is sealed by a cover plate, which has poor sealing effect, resulting in ash leakage and air leakage during the ash discharge process. In view of this, this application provides a sealing device for the ash discharge system of a solid slag discharge gasifier, which can ensure the tightness of the seal of the sampling port of the gasifier ash discharge system and avoid ash leakage and air leakage during the ash discharge process.
[0019] like Figure 1-4As shown, a sealing device for the ash discharge system of a solid slag gasifier is provided at the sampling port 31 of the ash conveying pipe 3 in the solid slag gasifier ash discharge system. The sealing device includes a connecting component 1 and a sealing component 2. The connecting component 1 is provided at the sampling port 31, and the sealing component 2 is provided on one side of the connecting component 1 to seal the sampling port 31.
[0020] Based on the above embodiments, the sealing component 2 is set at the sampling port 31 of the solid slag discharge gasifier ash discharge system by connecting component 1, and the sampling port 31 is sealed by sealing component 2 to solve the problem of ash leakage and gas leakage at sampling port 31. At the same time, by opening sealing component 2, coal ash in sampling port 31 and ash conveying pipe 3 can be sampled.
[0021] In this embodiment, as Figure 2 , Figure 4 As shown, the connecting assembly 1 includes a connecting pipe 11 connected to the sampling port 31. A valve seat 12 is connected to one side of the connecting pipe 11. A sealing hole 13 is provided through the middle of the valve seat 12 and communicates with the sampling port 31. A first gate post 14 and a second gate post 15 are connected to one side of the valve seat 12. A gate beam 16 is connected to one end of the first gate post 14 and the second gate post 15. One end of the gate beam 16 is rotatably connected to the end of the first gate post 14, and the other end of the gate beam 16 is movably connected to the end of the second gate post 15. A threaded hole is provided in the middle of the gate beam 16, and the center of the threaded hole and the center of the sealing hole 13 are on the same horizontal line.
[0022] The connecting pipe 11 is welded to the outside of the sampling port 31 to ensure the installation is secure; the connecting pipe 11 is connected to the valve seat 12 by bolts, and a set of mounting holes are opened on one side of the valve seat 12. The valve seat 12 is threadedly connected to the first gate post 14 and the second gate post 15 through the mounting holes.
[0023] In addition, U-shaped grooves 16-1 are provided at both ends of the door beam 16, and through holes are provided at both ends of the door beam 16. The through holes at both ends of the door beam 16 are connected to their corresponding U-shaped grooves 16-1. A first door post 14 and a second door post 15 are respectively provided in the U-shaped grooves 16-1 at both ends of the door beam 16. A connecting hole is provided at one end of the first door post 14 and the second door post 15. One end of the door beam 16 is rotatably connected to the first door post 14 through a fixing pin 17, a through hole and a connecting hole. The other end of the door beam 16 is connected to the second door post 15 through a movable pin 18, a through hole and a connecting hole. The movable pin 18 is connected to the door beam 16 through a chain. A handle 16-2 is provided at the end where the door beam 16 is connected to the second door post 15.
[0024] Based on the above embodiments, after the movable pin 18 is pulled out from the connecting hole of the second door post 15 and the through hole of the door beam 16, the door beam 16 can be rotated by the handle 16-2, so that the door beam 16 rotates around the fixed pin 17 connected to the first door post 14. The movable pin 18 can be connected to the door beam 16 by the chain to prevent the movable pin 18 from being lost after being taken out.
[0025] In this embodiment, as Figure 2-4 As shown, the sealing assembly 2 includes a valve core 21 disposed at the sealing hole 13 on the valve seat 12. A valve stem 22 is provided in the middle of one side of the valve core 21. The valve stem 22 is threadedly connected to the middle of the gate beam 16 through a threaded hole on the gate beam 16, and one end of the valve stem 22 extends to the outside of the gate beam 16 through the threaded hole.
[0026] The valve core 21 is connected to the valve stem 22 via a pressure plate 23 in the middle, and one end of the valve stem 22 is connected to a handle 24 via a lock nut.
[0027] Based on the above embodiments, the valve stem 22 and the gate beam 16 together form a lead screw assembly. By rotating the valve stem 22 through the handle 24, the valve stem 22 and the valve core 21 at its end can be moved relative to the gate beam 16. In addition, while rotating the gate beam 16, the gate beam 16 drives the valve stem 22 and the valve core 21 connected to it to move, so that the valve core 21 gradually moves away from the valve seat 12.
[0028] In this embodiment, an abutment hole 12-1 is provided on one side of the valve seat 12. The abutment hole 12-1 is connected to the interior of the sampling port 31 through the sealing hole 13. A frustum-shaped valve core 21 is movably connected to the interior of the sealing hole 13 and the abutment hole 12-1. The large-diameter end of the valve core 21 abuts against the inner wall of the abutment hole 12-1, and the small-diameter end of the valve core 21 extends into the sealing hole 13.
[0029] Based on the above embodiments, when the valve stem 22 is rotated, causing the valve core 21 to move, the valve core 21 can be moved out of the sealing hole 13 and the abutment hole 12-1 of the valve seat 12, or the valve core 21 can be moved into the abutment hole 12-1 and the sealing hole 13 of the valve seat 12. A stepped hole is formed by the abutment hole 12-1 and the sealing hole 13. When the valve core 21 is not moved out of the sealing hole 13 and the abutment hole 12-1, the abutment hole 12-1 and the sealing hole 13 limit the valve core 21, thereby locking the valve core 21 to the gate beam 16 through the valve stem 22. At this time, the gate beam 16 cannot be rotated, that is, when the valve core 21 is not moved out of the abutment hole 12-1, the valve core 21 cannot be opened by rotating the gate beam 16.
[0030] In addition, the thickness of the steel plate connecting pipe, valve seat and valve core is 30mm, and the thickness of the steel plate pressure plate is 10mm; to ensure the tightness of the seal on the sampling port 31, specifically in this embodiment, the dimensions of each component in the connecting assembly 1 and the sealing assembly 2 can be determined according to the actual situation.
[0031] The working principle of this utility model is as follows: the connecting pipe 11 is welded to the sampling port 31 of the ash conveying pipe 3 in the ash discharge system of the solid slag discharge gasifier. The valve core 21 is connected to the gate beam 16 through the valve stem 22. The gate beam 16 is connected to the valve seat 12 through the first gate post 14 and the second gate post 15. At this time, the valve core 21 is located between the valve seat 12 and the gate beam 16. Then, the valve seat 12 is installed on the connecting pipe 11 through bolts. When it is necessary to seal the sampling port 31, the valve stem 22 is rotated through the handle 24, so that the valve core 21 gradually approaches the abutment hole 12-1 and the sealing hole 13 of the valve seat 12, and the valve core 21 is gradually moved into the interior of the abutment hole 12-1 and the sealing hole 13, thereby sealing the sampling port 31 of the ash discharge system of the solid slag discharge gasifier, avoiding ash leakage and gas leakage in the gasifier, and thus avoiding the occurrence of safety accidents. When it is necessary to sample the coal ash from the gasifier, the valve stem 22 is rotated by the handle 24, causing the valve core 21 to gradually move out of the sealing hole 13 and the abutment hole 12-1, thus releasing the limit on the valve seat 21. At this time, the movable pin 18 is pulled out from the connection hole of the second gate post 15 and the through hole of the gate beam 16. The gate beam 16 can then be rotated by the handle 16-2. As the gate beam 16 rotates, it drives the valve stem 22 and the valve core 21 connected to it to rotate, causing the valve core 21 to gradually move away from the valve seat 12. This allows the coal ash to slide out from the inside of the ash conveying pipe 3 through the sampling port 31, the sealing hole 13 and the abutment hole 12-1, making it convenient for the staff to take samples.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
