A coke oven roof structure

Abstract

This utility model relates to the field of coke oven technology, specifically a coke oven top structure, including a shell. A fire observation hole is located at the center of the top of the shell. A water tank is fixedly connected to one side of the shell. A water injection groove is formed on the inner wall of the shell. A sliding groove is formed on the surface of the shell near the water injection groove. A support frame is slidably connected inside the sliding groove, and a cleaning component is rotatably connected to the top of the support frame. This utility model, through the arrangement of a water pump, connecting pipe, and water injection groove, allows water from the water tank to be pumped into the water injection groove through the connecting pipe when the water pump is started. Since the water injection groove is located at the interface between the coal charging hole and the riser pipe hole, when the coke oven starts and internal gas begins to escape, if there is a gap at the pipe hole interface that could allow gas to leak, the gas entering the gap will be absorbed by the water, preventing the gas from further expanding the gap, thereby achieving the effect of protecting the sealed interface.

Description

Technical Field

[0001] This utility model relates to the field of coke oven technology, specifically to a coke oven roof structure. Background Technology

[0002] A coke oven is a furnace used to refine coke. A modern coke oven consists of a carbonization chamber, combustion chamber, regenerator, inclined flue, roof, foundation, and flue. In the carbonization chamber, coal is heated and turned into coke under air-isolated conditions. The lifespan of a coke oven is generally around 25 years, but can reach over 30 years under good operation and maintenance. Modern coke ovens can be classified in various ways. The main differences between coke ovens with different structures lie in the following aspects: combustion chamber flue structure, adaptability to different types of heating gas, heating gas supply method, regenerator arrangement, and measures to improve the uniformity of heating in the upper direction.

[0003] The area above the top bricks of the coke oven carbonization chamber is called the furnace top zone. This zone contains coal charging holes, riser pipe holes, inspection holes, oven drying holes, and grate grooves. The furnace top zone has a certain thickness to support the load of the coal charging car and to prevent heat loss.

[0004] However, the existing coke oven roof structure has the following disadvantages:

[0005] (1) The existing coke oven top structure has a weak interface sealing function. During use, due to long-term use, gaps appear at the interface, and flue gas leaks out, further damaging the interface.

[0006] (2) The existing coke oven top structure has a weak cleaning function. During use, sediment is easily deposited at the bottom of the riser pipe, which can clog the riser pipe holes and make it difficult for the gas inside the coke oven to be discharged. Utility Model Content

[0007] The purpose of this invention is to provide a coke oven roof structure to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A coke oven roof structure includes a shell, a fire observation hole at the center of the top of the shell, a water tank fixedly connected to one side of the shell, a water injection groove on the inner wall of the shell, a sliding groove on the surface of the shell near the water injection groove, a support frame slidably connected inside the sliding groove, a cleaning component rotatably connected to the top of the support frame, a fixing block fixedly connected to one side of the cleaning component, a fixing plate fixedly connected to the surface of the fixing block, and a snap-fit ​​component fixedly connected to the inner wall of the fixing plate.

[0010] Preferably, the top two sides of the shell are provided with coal loading holes, and the bottom of the shell is provided with a coal outlet.

[0011] Preferably, a riser pipe hole is provided at the top of the shell near the coal loading hole, and a water inlet groove is provided on the surface of the shell.

[0012] Preferably, the surface of the water tank has a water inlet, and a filter screen is fixedly connected inside the water inlet.

[0013] Preferably, a water pump is fixedly connected to the inner bottom wall of the water tank, and a connecting pipe is fixedly connected to the outlet of the water pump.

[0014] Preferably, the cleaning assembly includes a connecting rod, an adjusting rod, and a spring button. The bottom end of the spring button is fixedly connected to the adjusting rod, the surface of the adjusting rod is slidably connected to the connecting rod, and the surface of the connecting rod is rotatably connected to the top end of the support frame.

[0015] Preferably, the snap-fit ​​assembly includes a connecting block, a snap-fit ​​block, and a spring. The snap-fit ​​block is fixedly connected to one side of the connecting block, and the spring is fixedly connected to the inner wall of the fixing plate on the side of the connecting block away from the snap-fit ​​block.

[0016] Preferably, a fixing rod is snapped into the inner wall of the fixing block, and a cleaning block is fixedly connected to the bottom end of the fixing rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This coke oven top structure, through the installation of a water pump, connecting pipes, and a water injection tank, allows for the following operation: when the water pump is started, water from the water tank is sent into the water injection tank through the connecting pipes. Since the water injection tank is located at the interface between the coal charging hole and the riser pipe hole, when the coke oven starts and internal gas begins to be discharged, if there is a gap at the pipe hole interface that could allow air to leak, the gas entering the gap will be absorbed by the water, preventing the gas from further expanding the gap, thereby achieving the effect of protecting the sealed interface.

[0019] 2. This coke oven top structure, through the arrangement of connecting rods, adjusting rods, fixing blocks, and cleaning blocks, is used as follows: First, the cleaning block is inserted downwards into the riser pipe hole. Then, the fixing rod is fixed to the fixing block using a snap-fit ​​assembly. Next, the adjusting rod is pulled out from inside the connecting rod, ensuring that the distance between the adjusting rod and the support frame is greater than the distance between the support frame and the fixing block. At this point, the adjusting rod is lifted upwards, and the fixing block causes the fixing rod to move downwards along with the cleaning block, pushing the tar adhering to the inside of the riser pipe hole into the coke oven, thereby achieving the effect of cleaning the riser pipe hole.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figures 1 to 4 As shown in the figure, a coke oven top structure according to an embodiment of the present invention includes a shell 1. A fire observation hole 4 is provided at the center of the top of the shell 1. A water tank 6 is fixedly connected to one side of the shell 1. A water injection groove 11 is provided on the inner wall of the shell 1. A sliding groove is provided on the surface of the shell 1 near the water inlet groove 5. A support frame 12 is slidably connected inside the sliding groove. A cleaning component 13 is rotatably connected to the top of the support frame 12. A fixing block 14 is fixedly connected to one side of the cleaning component 13. A fixing plate 15 is fixedly connected to the surface of the fixing block 14. A snap-fit ​​component 16 is fixedly connected to the inner wall of the fixing plate 15.

[0028] Specifically, the coal to be smelted is fed into the coke oven through the coal charging hole 2, and the coke oven is started. At this time, the water pump 9 is started, and the water stored in the water tank 6 is sent into the water injection tank 11 through the connecting pipe 10. Since the water injection tank 11 is located at the interface between the coal charging hole 2 and the riser pipe hole 3, when the coke oven starts and the internal gas begins to be discharged, if there is a gap at the pipe hole interface that can leak air, the gas entering the gap will be absorbed by the water, preventing the gas from further expanding the gap and protecting the sealing interface. When it rains, rainwater farther away from the water tank 6 will enter the water inlet trough 5, and then reach the top of the water tank 6 through the water inlet 7 to the filter screen 8. At this time, the filter screen 8 will filter the rainwater, blocking larger impurities outside the water tank 6 to prevent impurities from entering. When the substance enters the water tank 6, it damages the internal components of the water tank 6. When it is necessary to clean the riser hole 3, first insert the cleaning block 18 downward into the riser hole 3, then put the fixing rod 17 into the fixing block 14 and close the fixing block 14. At this time, move the connecting block 1601 away from the center of the fixing block 14, so that the locking block 1602 retracts into the left fixing plate 15. After the fixing block 14 is closed, release the connecting block 1601, and push the locking block 1602 into the right fixing plate 15 through the spring 1603 to limit the fixing rod 17. Then press the spring button 1303 to pull the adjusting rod 1302 out from the inside of the connecting rod 1301. After pulling it out, lift the adjusting rod 1302 upward, so that the fixing rod 17 carries the cleaning block 18 downward to clean the riser hole 3.

[0029] like Figure 1 As shown, coal loading holes 2 are provided on both sides of the top of the shell 1, and coal outlet 19 is provided at the bottom of the shell 1.

[0030] Specifically, the top two sides of the shell 1 are provided with coal charging holes 2, and the bottom of the shell 1 is provided with a coal outlet 19. When the coke oven is about to be put into use, the coal charging holes 2 are opened and the coal is sent into the coke oven through the coal charging holes 2 so that the coal can be smelted.

[0031] like Figure 1 As shown, a riser pipe hole 3 is provided at the top of the shell 1 near the coal loading hole 2, and a water inlet trough 5 is provided on the surface of the shell 1.

[0032] Specifically, a riser pipe hole 3 is provided at the top of the shell 1 near the coal loading hole 2, and a water inlet trough 5 is provided on the surface of the shell 1. When it rains, rainwater that is far away from the water tank 6 will enter the water inlet trough 5, and then reach the top of the water tank 6 through the water inlet trough 5 and enter the water tank 6, thereby increasing the collection speed of rainwater in the water tank 6.

[0033] like Figures 1 to 2 As shown, a water inlet 7 is provided on the surface of the water tank 6, and a filter screen 8 is fixedly connected inside the water inlet 7.

[0034] Specifically, the surface of the water tank 6 is provided with a water inlet 7, and a filter screen 8 is fixedly connected inside the water inlet 7. When rainwater reaches the top of the water tank 6, it will pass through the water inlet 7 to the filter screen 8. At this time, the filter screen 8 will filter the rainwater and block larger impurities outside the water tank 6 to prevent impurities from entering the water tank 6 and causing damage to the internal components of the water tank 6.

[0035] like Figure 2 As shown, a water pump 9 is fixedly connected to the inner bottom wall of the water tank 6, and a connecting pipe 10 is fixedly connected to the outlet of the water pump 9.

[0036] Specifically, a water pump 9 is fixedly connected to the inner bottom wall of the water tank 6, and a connecting pipe 10 is fixedly connected to the outlet of the water pump 9. When the coke oven is started, the water pump 9 is started, and the water stored inside the water tank 6 is sent into the water injection tank 11 through the connecting pipe 10. When the gas inside the coke oven is discharged from the coke oven through the coal charging hole 2 and the riser pipe hole 3, the water will protect the interface of the pipe hole to prevent the gas from corroding the gap when it passes through the gap and further widening the gap.

[0037] like Figure 1 As shown, a fixing rod 17 is snapped into the inner wall of the fixing block 14, and a cleaning block 18 is fixedly connected to the bottom end of the fixing rod 17.

[0038] Specifically, a fixing rod 17 is snapped into the inner wall of the fixing block 14, and a cleaning block 18 is fixedly connected to the bottom end of the fixing rod 17. When it is necessary to clean the riser hole 3 on the top of the coke oven, the cleaning block 18 is inserted into the riser hole 3, and the fixing rod 17 is fixed to the fixing block 14 through the snap-fit ​​assembly 16. At this time, the riser hole 3 can be cleaned through the cleaning assembly 13 to prevent the riser hole 3 from being blocked and affecting the gas inside the coke oven from being difficult to discharge.

[0039] Example 2

[0040] As Figures 1 to 3 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the cleaning component 13 includes a connecting rod 1301, an adjusting rod 1302 and a spring button 1303. The bottom end of the spring button 1303 is fixedly connected to the adjusting rod 1302, the surface of the adjusting rod 1302 is slidably connected to the connecting rod 1301, and the surface of the connecting rod 1301 is rotatably connected to the top end of the support frame 12.

[0041] Specifically, the cleaning component 13 includes a connecting rod 1301, an adjusting rod 1302, and a spring button 1303. The adjusting rod 1302 is fixedly connected to the bottom end of the spring button 1303, and the connecting rod 1301 is slidably connected to the surface of the adjusting rod 1302. The surface of the connecting rod 1301 is rotatably connected to the top end of the support frame 12. When it is necessary to clean the riser hole 3 on the top of the coke oven, first insert the fixing rod 17 into the riser hole 3 and fix it on the fixing block 14. Then press the spring button 1303 to pull the adjusting rod 1302 out from the inside of the connecting rod 1301. After pulling it out, lift the adjusting rod 1302 upwards so that the fixing rod 17 carries the cleaning block 18 downwards to clean the riser hole 3.

[0042] As Figures 1 to 4 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the snap-fit ​​assembly 16 includes a connecting block 1601, a snap-fit ​​block 1602 and a spring 1603. The snap-fit ​​block 1602 is fixedly connected to one side of the connecting block 1601, the spring 1603 is fixedly connected to the side of the connecting block 1601 away from the snap-fit ​​block 1603, and the inner wall of the fixing plate 15 is fixedly connected to the side of the spring 1603 away from the connecting block 1601.

[0043] Specifically, the snap-fit ​​assembly 16 includes a connecting block 1601, a snap-fit ​​block 1602, and a spring 1603. The snap-fit ​​block 1602 is fixedly connected to one side of the connecting block 1601, and the spring 1603 is fixedly connected to the side of the connecting block 1601 away from the snap-fit ​​block 1603. The inner wall of the fixing plate 15 is fixedly connected to the side of the spring 1603 away from the connecting block 1601. After the fixing rod 17 is placed into the fixing block 14, the fixing block 14 is closed. At this time, the connecting block 1601 is moved away from the center of the fixing block 14, so that the snap-fit ​​block 1602 retracts into the left fixing plate 15. After the fixing block 14 is closed, the connecting block 1601 is released, and the snap-fit ​​block 1602 is pushed into the right fixing plate 15 by the spring 1603 to limit the fixing rod 17.

[0044] Working principle: Coal to be smelted is fed into the coke oven through the coal charging hole 2. The coke oven is started, and at the same time, the water pump 9 is activated, sending water stored in the water tank 6 into the water injection tank 11 through the connecting pipe 10. Since the water injection tank 11 is located at the interface between the coal charging hole 2 and the riser pipe hole 3, when the coke oven starts and internal gas begins to escape, if there is a gap at the pipe hole interface that could allow air to leak, the gas entering the gap will be absorbed by the water, preventing the gas from further expanding the gap and protecting the sealing interface. When it rains, rainwater from locations farther from the water tank 6 will enter the water inlet trough 5, then reach the top of the water tank 6 through the water inlet 7, and finally reach the filter screen 8. The filter screen 8 will filter the rainwater, blocking larger impurities outside the water tank 6, preventing contamination. When the substance enters the water tank 6, it damages the internal components of the water tank 6. When it is necessary to clean the riser hole 3, first insert the cleaning block 18 downward into the riser hole 3, then put the fixing rod 17 into the fixing block 14 and close the fixing block 14. At this time, move the connecting block 1601 away from the center of the fixing block 14, so that the locking block 1602 retracts into the left fixing plate 15. After the fixing block 14 is closed, release the connecting block 1601, and push the locking block 1602 into the right fixing plate 15 through the spring 1603 to limit the fixing rod 17. Then press the spring button 1303 to pull the adjusting rod 1302 out from the inside of the connecting rod 1301. After pulling it out, lift the adjusting rod 1302 upward, so that the fixing rod 17 carries the cleaning block 18 downward to clean the riser hole 3.
