Description

Technical Field

[0001] The utility model relates to the technical field of cleaning a coke oven carbonization chamber, in particular to a graphite cleaning device for a carbonization chamber. Background Art

[0002] The coal is heated to high temperature in the carbonization chamber and gradually decomposed into volatiles and gaseous products. These volatiles include CO, H 2 , C 2 H 4 Elements such as carbon dioxide and water vapor react with oxygen in the air. Further, under the high temperature and high pressure environment of the carbonization chamber, the volatile carbon atoms begin to recombine to form graphite, and attach to the furnace wall bricks and furnace roof bricks, and finally form furnace wall graphite and furnace roof graphite after a period of time. Objectively speaking, when graphite exists in a small amount, it can block some gaps in the coke oven masonry, which plays a positive role in the tightness of the furnace wall. However, with the excessive growth of graphite, too thick graphite will seriously affect the heat transfer and production capacity of the coke oven, and its negative impact on the coke oven is getting bigger and bigger, especially in the middle and upper part of the carbonization chamber. Because the graphite is more and thicker than other parts, the carbonization chamber becomes narrower here, and even forms a bottleneck, which makes it easy to push the coke. And due to the presence of graphite, the thermal resistance of the furnace wall will become larger. Under the same conditions, in order to make the coke cake mature, the temperature can only be increased, which not only increases the heat consumption, but also accelerates the growth of graphite, forming a vicious circle. Therefore, in the production management of coke ovens, removing the graphite on the top of the carbonization chamber is one of the very important processes, and the excess graphite can be cleaned regularly.

[0003] There are two main methods for cleaning graphite in the carbonization chamber: one is to burn the empty furnace, that is, to draw air from the coal loading port into the carbonization chamber by the thermal buoyancy of the riser to burn the graphite on the top. However, this method is only applicable to the parts of the furnace wall in the carbonization chamber where there is less graphite, and it is difficult to be effective in the short term for the parts on the top of the carbonization chamber where there is more graphite. Moreover, burning the empty furnace also affects the production efficiency and progress. The second is to use the coke pushing equipment, that is, to clean the coke pushing rod, that is, to install a compressed air pipe on the top of the coke pushing rod, and use compressed air to blow the graphite on the top of the carbonization chamber with strong winds during the coke pushing process. However, the compressed air blowing nozzle is too close to the furnace top bricks, which is easy to impact the brick surface and brick seams, and it is very easy to cause leakage from the furnace top, which has environmental and safety hazards, and is not suitable for cleaning the inner wall of the carbonization chamber where a relatively firm coke layer is bonded to the inner wall due to long-term adhesion. There are defects such as low cleaning efficiency, incomplete cleaning, and unsatisfactory cleaning effect, and it cannot achieve effective cleaning inside the carbonization chamber.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1-Figure 3, a graphite cleaning device for a carbonization chamber comprises: a fixing component, a cleaning component and a matching combustion component; the fixing component is fixedly connected to the upper front side of a coke pushing rod 1 having a trapezoidal longitudinal section; the cleaning component is positioned on the coke pushing rod 1 through the fixing component, and the top of the cleaning component is higher than the top of the coke pushing rod 1; the fixing component comprises two L-shaped ear seats 2 arranged opposite to each other, each ear seat 2 is arranged at the left and right edges of the coke pushing rod 1, and the cleaning component is vertically inserted between the ear seats 2 and the coke pushing rod 1; the cleaning component comprises a scraper 3 of a T-shaped structure, and a wear-resistant scraper 4 is arranged on the top of the scraper 3; a matching combustion component is arranged on the upper rear side of the hollow coke pushing rod 1, and the matching combustion component is located behind the cleaning component, and the matching combustion component comprises an air outlet pipe 5 horizontally connected to the rear side of the coke pushing rod 1, and a plurality of air outlet holes are evenly distributed on the air outlet pipe 5, and a plurality of air outlet nozzles 51 with different directions are connected to the air outlet holes; an air supply pipe 52 is connected to the rear side of the air outlet pipe 5, and the air supply pipe 52 is fixed to the back of the coke pushing rod 1.

[0024] The cleaning component is detachable, and the scraper 3 is fixed between the ear seat 2 and the coke pushing rod 1 through the limited position cooperation between the two, which is used to limit the lateral and longitudinal movement of the scraper 3 to prevent it from being displaced or falling during use. When it is needed, the scraper 3 can be directly inserted into the ear seat 2 and used directly in production. When it is not used or needs to be repaired, the scraper 3 can be directly taken out, which is easy to operate. The top of the cleaning component is higher than the top of the coke pushing rod 1, that is, the top of the scraper 3 and / or the wear-resistant scraper 4 is higher than the top of the coke pushing rod 1, so as to achieve the purpose of cleaning the graphite on the top of the coke oven carbonization chamber. The wear-resistant scraper 4 is a plane scraper commonly used in the art, which will not be described here.

[0025] The longitudinal section of the gas outlet pipe 5 can be square, circular or other shapes as long as the gas medium can be dispersed. It is preferably square to facilitate the installation of gas outlet nozzles 51 in different directions. The gas outlet nozzle 51 is preferably installed on the front side of the gas outlet pipe 5 to facilitate the spraying of the scattered graphite powder.

[0026] During operation, the scraper 3 is inserted into the ear seat 2 and fixed, and then the scraper 3 is sent into the carbonization chamber along with the coke pushing rod 1. The wear-resistant scraper 4 on the top of the scraper 3 of the cleaning component cleans the graphite on the top of the carbonization chamber, and then the combustion medium released by the gas outlet nozzle 51 on the gas outlet pipe 5 of the matching combustion component is used to directly burn the cleaned graphite powder in the high-temperature carbonization chamber, thereby improving the cleaning efficiency and cleaning effect, and there is no need to recycle the graphite powder. When the coke pushing rod 1 is retracted, the wear-resistant scraper 4 can also perform secondary cleaning on the graphite layer of the top wall, thereby achieving the purpose of improving the cleaning effect, timely cleaning the graphite on the top of the carbonization chamber, reducing the resistance of coke pushing, and ensuring the normal and stable production of the coke oven.

[0027] The coke pushing rod 1 is a coke pushing device commonly used in the prior art, and its longitudinal section is an irregular trapezoidal shape. The size and specific shape of the coke pushing rod 1 are determined according to the size of the carbonization chamber door in actual application, and are not limited in the present utility model. The angle of inclination between the specific trapezoidal inclined surfaces is not limited and needs to be determined according to actual conditions. Since the carbonization chamber is in a high temperature state during use, the entire cleaning device is made of high temperature resistant materials and should maintain mechanical properties unchanged under a high temperature environment of 1300°C. Moreover, the scraper 3 and the wear-resistant scraper 4 also have good wear resistance to extend their service life.

[0028] like Figure 2 Preferably, the inlet end of the air supply pipe 52 is connected to the gas storage device 53, and the medium transported in the air supply pipe 52 is 0.6MPa compressed air. The air supply pipe 52 is also made of high temperature resistant material, and a conventional air pipe winding component is provided on the air supply pipe 52, so that the air supply pipe 52 can move to different positions with the coke pushing rod 1 without affecting the transportation of compressed air therein. The gas storage device 53 is used for storing compressed air and providing reserve gas for the air supply pipe 52 and the air outlet pipe 5. Of course, the medium in the air supply pipe 52 is not limited to compressed air. Any medium and its pressure that can deliver oxygen to help graphite burn can be selected by those skilled in the art according to the production environment. Similarly, the pressure of compressed air is not limited to 0.6MPa, but the preferred 0.6MPa compressed air can blow the graphite powder to a position away from the device while supporting combustion, preventing the high temperature of its combustion from causing high temperature damage to the device.

[0029] Preferably, the air delivery pipe 52 is fixed to the back of the coke pushing rod 1. When pushing coke, the air outlet nozzle 51 of the air outlet pipe 5 continuously sprays compressed air to promote the combustion of graphite. At the same time, the compressed air blown by the air outlet nozzle 51 partially toward the back of the scraper 3 can cool the scraper 3, thereby reducing the adverse effects of the cleaning components in the high temperature environment of the carbonization chamber and extending their service life.

[0030] Example 2

[0031] like Figure 3On the basis of the above embodiment, in this embodiment: the scraper 3 includes an integrally formed horizontal plate 31 and a vertical plate 32, the horizontal plate 31 and the vertical plate 32 are perpendicular to each other; the length of the horizontal plate 31 is greater than the length of the coke pushing rod 1; the bottom of the horizontal plate 31 abuts against the top of the plug-in seat 2, and the left and right sides of the vertical plate 32 contact the inner wall of the plug-in seat 2. The bottom of the horizontal plate 31 is limitedly matched with the top of the plug-in seat 2 to limit the downward movement of the scraper 3; the left and right sides of the vertical plate 32 are limitedly matched with the inner wall of the plug-in seat 2 to limit the movement of the scraper 3 in the left and right directions, thereby improving the installation and use stability of the cleaning components. In the left and right directions, the length of the horizontal plate 31 is greater than the length of the coke pushing rod 1, which facilitates the contact between the scraper 3 and the wear-resistant scraper 4 and the furnace wall, and the length of the vertical plate 32 is less than or equal to the length of the coke pushing rod 1, which facilitates its insertion and limiting.

[0032] Example 3

[0033] like Figure 3 On the basis of the above-mentioned embodiment, in this embodiment: vertical wear-resistant scrapers 4 are provided on the left and right edges of the horizontal plate 31. The wear-resistant scrapers 4 on the side of the horizontal plate 31 can clean the graphite layer adhered to the side wall close to the top wall, and also clean the position that is easy to form a dead angle, thereby improving the cleaning effect. When the cleaning component is working, the main wear part is the wear-resistant scraper 4. When the wear-resistant scraper 4 is worn to a certain extent, it can be replaced (for example, the wear-resistant scraper 4 is cut off with a cutting knife, and a new wear-resistant scraper 4 is directly welded), without replacing a new scraper 3, and the operation cost of the device is significantly reduced.

[0034] like Figure 2 and Figure 3 Preferably, the fixing member further comprises a fence 21 arranged at the front side of the coke pushing rod 1, and the lower part of the vertical plate 32 is inserted between the fence 21 and the coke pushing rod 1. The fence 21 mainly plays a role in fixing the scraper 3, and the ear seat 2 and the fence 21 are used in conjunction to prevent the scraper 3 from deforming or falling during the coke pushing process, thereby improving the stability of the cleaning member.

[0035] When the coke push rod 1 enters and leaves the carbonization chamber, the scraper 3 will clean the graphite layer. When the cleaned graphite powder falls on the front end of the scraper 3, it can be ignited by high temperature. When the graphite powder falls on the rear end of the scraper 3, in order to keep the coke push rod 1 clean, Figure 2 Preferably, a collecting bucket 41 is connected to the back of the scraper 3, and the bottom plate of the collecting bucket 41 is arranged above the coke pushing rod 1. The collecting bucket 41 is used to collect the scraped graphite powder to avoid the graphite powder from splashing. When the coke pushing is completed, the collecting bucket 41 is moved out of the coke oven along with the coke pushing rod 1, and then the graphite in the collecting bucket 41 can be cleaned. The length of the collecting bucket 41 in the front-to-back direction is not less than the length of the coke pushing rod 1.

[0036] Example 4

[0037] The scraper 3 and the wear-resistant scraper 4 are hard in texture. Even if they are used to scrape the graphite layer, there is still a problem that the contact force between them and the graphite layer cannot be adjusted in time according to the thickness of the graphite layer, which will cause the wear-resistant scraper 4 to easily damage the furnace wall when cleaning the thin graphite layer. Therefore, if Figure 4 On the basis of the above embodiments, in this embodiment: two groups of buffer components are arranged between the ear socket 2 and the scraper 3; each group of buffer components includes a positioning rod 22 arranged on the top of each ear socket 2 and a positioning groove 33 correspondingly arranged at the bottom of the horizontal plate 31, and each positioning rod 22 is inserted into the corresponding positioning groove 33; a spring 34 is fixedly connected to the top wall of each positioning groove 33, and the bottom end of the spring 34 is movably connected to the top of the positioning rod 22.

[0038] When the scraper 3 is inserted into the ear socket 2, the positioning rod 22 on the ear socket 2 is inserted into the positioning groove 33 at the bottom of the horizontal plate 31, and the spring 34 abuts against the top of the positioning rod 22 under the action of gravity. The connection mode between the scraper 3 and the ear seat 2 is optimized to be connected by a spring 34. During operation, the wear-resistant scraper 4 contacts the top wall of the carbonization chamber. When encountering a thicker graphite layer, the front end of the wear-resistant scraper 4 is blocked, and the scraper 3 will squeeze the spring 34, thereby adjusting the height of the wear-resistant scraper 4 and the scraper 3, and timely adjusting and buffering the contact force between the wear-resistant scraper 4 and the graphite layer, protecting the wear-resistant scraper 4 from being damaged by excessive resistance, extending the service life of the wear-resistant scraper 4, and avoiding scratching the top wall behind the graphite layer. When the thickness of the graphite layer at the front end decreases, the spring 34 rebounds so that the wear-resistant scraper 4 can always abut against the graphite layer and clean the graphite layer, which can not only scrape off the graphite layer on the top of the carbonization chamber, but also prevent the furnace wall from being damaged.

[0039] The utility model provides a carbonization chamber graphite cleaning device. When working, the scraper 3 is inserted into the ear seat 2 and fixed, and the vertical plate 32 is inserted into the fence 21, and the top of the scraper 3 and / or the wear-resistant scraper 4 is higher than the top of the coke pushing rod 1, wherein the bottom of the horizontal plate 31 is limitedly matched with the top of the ear seat 2, the left and right sides of the vertical plate 32 are limitedly matched with the inner wall of the ear seat 2, and the positioning rod 22 on the ear seat 2 is inserted into the positioning groove 33 at the bottom of the horizontal plate 31, and under the action of gravity, the spring 34 abuts against the top of the positioning rod 22.

[0040] When the coke pushing rod 1 is used for pushing coke, the scraper 3 is sent into the carbonization chamber along with the coke pushing rod 1, and the wear-resistant scraper 4 on the top of the scraper 3 cleans the graphite on the top of the carbonization chamber, and the wear-resistant scraper 4 on the side of the horizontal plate 31 can clean the graphite layer adhered to the side wall close to the top wall which is easy to form a dead angle. When cleaning, the wear-resistant scraper 4 contacts the top wall of the carbonization chamber. When encountering a thicker graphite layer, the front end of the wear-resistant scraper 4 is blocked, and the scraper 3 will squeeze the spring 34, thereby adjusting the height of the wear-resistant scraper 4 and the scraper 3, and timely adjusting and buffering the contact force between the wear-resistant scraper 4 and the graphite layer, protecting the wear-resistant scraper 4 from being easily damaged by excessive resistance. When the thickness of the graphite layer at the front end decreases, the spring 34 rebounds so that the wear-resistant scraper 4 can always abut against the graphite layer and clean the graphite layer, which can not only scrape off the graphite layer on the top of the carbonization chamber, but also prevent the furnace wall from being damaged.

[0041] While cleaning the graphite, the combustion medium (i.e., 0.6MPa compressed air) in the gas storage device 53 is sent to the gas outlet pipe 5 by the gas delivery pipe 52, and then released by the gas outlet nozzle 51 on the gas outlet pipe 5, so that the cleaned graphite powder can be directly burned in the high-temperature carbonization chamber without the need to recycle the graphite powder. At the same time, the compressed air blown out by the gas outlet nozzle 51 partially toward the back of the scraper 3 cools the scraper 3, thereby reducing the adverse effects of the cleaning components in the high-temperature environment of the carbonization chamber and extending their service life.

[0042] When the coke pushing rod 1 is retracted, the wear-resistant scraper 4 can also perform a secondary cleaning of the graphite layer on the top wall to achieve the purpose of improving the cleaning effect. Since the graphite powder is easy to fall on the rear end of the scraper 3 at this time, the scraped graphite powder is collected by the collecting bucket 41 to avoid the graphite powder from splashing. When the coke pushing is completed, the collecting bucket 41 is moved out of the coke oven with the coke pushing rod 1, and the graphite in the collecting bucket 41 can be cleaned. When the wear-resistant scraper 4 is worn to a certain extent, it can be replaced without replacing a new scraper 3, and the operating cost of the device is reduced.

[0043] It should be noted that in the present invention, the detailed structure of some devices is not described in detail, but belongs to the prior art known to those skilled in the art, so it will not be repeated here. In addition, the parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
