Description

Technical Field

[0001] This utility model relates to the field of coking oven machinery technology, specifically a coking guide grid for a side-loading coking oven. Background Technology

[0002] As a key component of the quenching car in a side-loading coke oven, the coke guide grid's main function is to guide and intercept the red-hot coke during the coke ejection process, ensuring that the coke falls accurately and smoothly into the quenching car, while preventing coke from scattering or damaging the equipment. The existing quenching car's guide grid is primarily a welded frame, with several channel steels arranged longitudinally along the coke oven within the frame. The front ends of the channel steels directly contact the end face of the coke oven column. When the quenching car moves into position, the front ends of the channel steels undergo a momentary rigid collision with the column and withstand the impact and friction of the high-temperature (≈1050 ℃) red-hot coke.

[0003] The existing coke guide grid channel steel front end is easily bent and deformed by thermal-mechanical coupling, resulting in a short average lifespan. Furthermore, gaps appear between the deformed channel steel and the furnace column, causing red coke ash to leak out and serious dust pollution on site. This not only pollutes the environment but also increases the workload of on-site cleaning. Frequent replacement of channel steel increases spare parts costs and maintenance downtime. Utility Model Content

[0004] The purpose of this utility model is to provide a coke guide grid for a side-loading coke oven, in order to solve the problems mentioned above, such as the channel steel front end being easily bent and deformed by thermal-mechanical coupling, resulting in a low average lifespan, and gaps appearing between the deformed channel steel and the furnace column, causing red coke ash to leak out and serious dust pollution on site.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coke guide grid for a side-loading coke oven includes a rectangular frame. Several channel steels are fixedly connected within the frame. One end of each channel steel forms an installation groove with one side of the frame. A vertical liner plate is detachably installed within the installation groove. A buffer pad is embedded between the channel steel and the vertical liner plate. The vertical liner plate is used to receive high-temperature coke, and one end face of the vertical liner plate is used to contact the furnace column.

[0007] As a further embodiment of this utility model: the upright liner plate is provided with multiple countersunk holes, and countersunk bolts are installed in the countersunk holes and fixedly installed with the frame.

[0008] As a further embodiment of this utility model: edging iron plates are welded to both sides of the frame, and a side liner is installed on one side of the edging iron plate. Multiple countersunk holes are opened on the side liner, and countersunk bolts are installed in the countersunk holes and fixedly installed with the edging iron plate.

[0009] As a further embodiment of this utility model: the vertical liner and the side liner are both heat-resistant steel or high-chromium-nickel heat-resistant cast steel, and the thickness of the vertical liner and the side liner is 15mm-30mm.

[0010] As a further embodiment of this utility model: the upright liner is a composite structure of tungsten carbide weld overlay and steel substrate, and the thickness of the tungsten carbide weld overlay is 5mm-10mm.

[0011] As a further embodiment of this utility model: the contact end face between the vertical lining plate and the furnace column is provided with a chamfer, and the radius of the chamfer is 3mm-5mm.

[0012] As a further embodiment of this utility model: a plurality of the channel steels are arranged at equal intervals on the frame, and the plurality of the channel steels are set on the same horizontal plane.

[0013] As a further embodiment of this utility model: the buffer pad is made of asbestos material, and the buffer pad is used for thermal expansion buffering of the channel steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, when high-temperature coke is introduced, the heat-resistant and wear-resistant vertical liner plate mainly bears the coke, thereby reducing the contact time between the channel steel and the coke, thus avoiding direct contact between the front end of the channel steel and the furnace column, preventing the channel steel from being deformed by high-temperature impact, and improving the service life of the channel steel. In addition, the vertical liner plate and the furnace column form a line-surface contact, reducing ash leakage. At the same time, a buffer pad is embedded between the channel steel and the vertical liner plate to provide expansion and contraction space when the channel steel is hot-deformed, preventing the channel steel from being squeezed and deformed. The buffer pad can fill the gap between the channel steel and the vertical liner plate, further reducing ash leakage and preventing dust from occurring.

[0016] 2. In this utility model, the vertical liner plate can be detachably installed in the installation groove, which is more convenient than the existing frame and channel steel milling and modification, effectively reducing costs. Moreover, after long-term use, when the vertical liner plate is greatly worn, the detachable vertical liner plate can be easily and quickly replaced, reducing maintenance downtime. The multiple countersunk holes on the vertical liner plate facilitate the hidden installation of countersunk bolts, thereby maintaining the flatness of the upper surface of the vertical liner plate and facilitating the smooth introduction of high-temperature coke.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-2 In this embodiment of the present invention, a coke guide grid for a side-loading coke oven includes a rectangular frame 1. Several channel steels 2 are fixedly connected inside the frame 1. One end of the channel steels 2 and one side of the frame 1 form an installation groove. A vertical liner plate 3 is detachably installed in the installation groove. A buffer pad 4 is embedded between the channel steels 2 and the vertical liner plate 3. The vertical liner plate 3 is used to receive high-temperature coke, and one end face of the vertical liner plate 3 is used to contact the furnace column.

[0023] Specifically, several channel steels 2 are welded onto a rectangular frame 1. A vertical liner plate 3 is connected to one end of each channel steel 2. The vertical liner plate 3 is in flexible contact with the furnace column. When high-temperature coke is introduced, the heat-resistant and wear-resistant vertical liner plate 3 mainly bears the coke, thereby reducing the contact time between the channel steel 2 and the coke. This avoids direct contact between the front end of the channel steel 2 and the furnace column, prevents the channel steel 2 from deforming due to high-temperature impact, and improves the service life of the channel steel 2. Furthermore, the vertical liner plate 3 forms a line-to-surface contact with the furnace column, reducing ash leakage. At the same time, a buffer pad 4 is placed between the channel steel 2 and the vertical liner plate 3 to provide expansion and contraction space when the channel steel 2 undergoes thermal deformation, preventing the channel steel 2 from undergoing extrusion deformation. The buffer pad 4 can fill the gap between the channel steel 2 and the vertical liner plate 3, further reducing ash leakage and preventing dust from occurring.

[0024] Furthermore, the mounting slot is equipped with a detachable vertical liner plate 3, which is more convenient to modify than the existing frame 1 and channel steel 2 by milling and flattening, effectively reducing costs. Moreover, after long-term use, the detachable vertical liner plate 3 can be easily and quickly replaced after significant wear, reducing maintenance downtime and improving performance.

[0025] Preferred, such as Figure 1 As shown, the upright liner plate 3 has multiple countersunk holes 5, and countersunk bolts are installed in the countersunk holes 5 and fixedly installed with the frame 1.

[0026] Specifically, the multiple countersunk holes 5 on the vertical liner plate 3 facilitate the concealed installation of countersunk bolts, thereby maintaining the flatness of the upper surface of the vertical liner plate 3 and facilitating the smooth introduction of high-temperature coke.

[0027] Preferred, such as Figure 1As shown, the frame 1 has edging iron plates 6 welded on both sides. A side liner 7 is installed on one side of the edging iron plate 6. Multiple countersunk holes 5 are opened on the side liner 7. Countersunk bolts are installed in the countersunk holes 5 and fixedly installed with the edging iron plate 6.

[0028] Specifically, the multiple countersunk holes 5 on the side liner plate 7 facilitate the concealed installation of countersunk bolts, thereby maintaining the flatness of the side end face of the side liner plate 7 and ensuring that the coke is not obstructed during transmission due to unevenness of the side end face. In addition, the setting of the edge banding plate 6 enhances the structural strength of both sides of the frame 1 and improves the stability of the overall device. The side liner plate 7 and the edge banding plate 6 are fixed with countersunk bolts, which not only ensures a firm installation, but also allows for convenient and quick disassembly and replacement when the side liner plate 7 is worn and needs to be replaced, reducing maintenance costs and time.

[0029] Preferably (not shown in the figure), the vertical liner 3 and the side liner 7 are both heat-resistant steel or high chromium-nickel heat-resistant cast steel, and the thickness of the vertical liner 3 and the side liner 7 is 15mm-30mm.

[0030] Specifically, the vertical liner 3 and the side liner 7 are made of heat-resistant steel or high-chromium-nickel heat-resistant cast steel. In the working environment of high-temperature coke transmission, they have excellent heat resistance and mechanical strength, and can withstand high temperatures without deformation or damage, thus ensuring the long-term stable operation of the vertical liner 3 and the side liner 7. The thickness of the vertical liner 3 and the side liner 7 is 15mm-30mm, preferably 15mm. When the end face of the furnace column bulges locally due to thermal deformation, the thickness of the vertical liner 3 and the side liner 7 can be adjusted to 15mm. While ensuring the strength and durability of the vertical liner 3 and the side liner 7, the portability and economy of the equipment are also taken into account.

[0031] Preferably (not shown in the figure), the vertical liner 3 is a composite structure of tungsten carbide weld overlay and steel substrate, and the thickness of the tungsten carbide weld overlay is 5mm-10mm.

[0032] Specifically, the vertical liner plate 3 adopts a composite structure of tungsten carbide weld overlay and steel substrate, which gives the vertical liner plate 3 both the high hardness and high wear resistance of tungsten carbide to reduce weight, and the good toughness and machinability of steel substrate. The thickness of the tungsten carbide weld overlay is 5mm-10mm, which can effectively ensure that the vertical liner plate 3 has sufficient wear resistance life in the process of frequent friction contact with coke, reducing the replacement frequency due to wear. At the same time, the steel substrate provides stable support for the tungsten carbide weld overlay, ensuring the reliability of the overall structure of the vertical liner plate 3.

[0033] Preferably (not shown in the figure), the contact end face between the vertical lining plate 3 and the furnace column is chamfered, and the radius of the chamfer is 3mm-5mm.

[0034] Specifically, the vertical lining plate 3 is chamfered, and the chamfer of the vertical lining plate 3 contacts the furnace column to form a line-to-surface contact, so as to adapt to changes in the contact surface.

[0035] Preferred, such as Figure 1 As shown, several channel steels 2 are arranged at equal intervals on the frame 1, and the several channel steels 2 are set on the same horizontal plane.

[0036] Specifically, the equidistantly arranged channel steels 2 provide a stable installation foundation for the vertical liner plate 3, ensuring that the vertical liner plate 3 remains flat after installation. Since several channel steels 2 are set on the same horizontal plane, stress concentration caused by height differences can be effectively avoided, thus extending the service life of the equipment.

[0037] Preferably (not shown in the figure), the buffer pad 4 is made of asbestos material and is used for thermal expansion buffering of the channel steel 2.

[0038] Specifically, the buffer pad 4 made of asbestos material has excellent heat resistance and buffering performance. When the channel steel 2 expands due to temperature changes, the buffer pad 4 can effectively absorb and disperse the stress generated, preventing the channel steel 2 from squeezing each other or putting excessive pressure on the frame 1 due to thermal expansion, thereby ensuring the stability and safety of the overall structure of the equipment.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
