[0035] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0036] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0037] In order to solve the problems in the background technology, the utility model discloses a cleaning device for the smoke guide pipe of the carbonization chamber of a coke oven. Figure 1 As shown, the cleaning device for the smoke duct of the coke oven carbonization chamber comprises a track 1, a connecting frame 2, a cover lifting mechanism 3 and a cleaning mechanism.

[0038] The track 1 is connected to the connecting frame 2, and the connecting frame 2 is slidably matched with the track 1, so that the connecting frame 2 can move along the track 1. The track 1 can be, but is not limited to, an I-beam. The track 1 can be, but is not limited to, set on a smoke guide vehicle. The smoke from the coke oven can enter the smoke guide vehicle through a pipe, and the smoke guide vehicle can be moved to collect the smoke from the coke oven and process the smoke. The length of the track 1 must ensure that the lifting point of the cover lifting mechanism 3 and the center of the cleaning head 11 of the cleaning mechanism can be moved to the top of the smoke guide pipe.

[0039] The connecting frame 2 is arranged on the track 1 and can move along the track 1. The connecting frame 2 serves as the installation structural foundation of the lid lifting mechanism 3 and the cleaning mechanism. The connecting frame 2 can be, but is not limited to, a connecting plate, and mounting holes for installing the lid lifting mechanism 3 and the cleaning mechanism can be provided on the connecting plate. When the connecting frame 2 moves along the track 1, the lid lifting mechanism 3 and the cleaning mechanism arranged on the connecting frame 2 move synchronously with the connecting frame 2.

[0040] The cover lifting mechanism 3 is arranged on the connecting frame 2, and the cover lifting mechanism 3 is used to lift and lower the furnace cover of the smoke guide pipe. The smoke guide pipe is generally arranged at the top of the carbonization chamber of the coke oven, and the furnace cover is arranged at the smoke guide port of the smoke guide pipe or arranged in the smoke guide pipe. When the furnace cover is placed at the smoke guide port of the smoke guide pipe or arranged in the smoke guide pipe, it is used to block the smoke guide pipe. The smoke guide pipe can generally be vertically arranged at the top of the carbonization chamber. Of course, it can be understood that the smoke guide pipe can be horizontally or obliquely arranged at the top of the carbonization chamber. The following will be described as an example of the smoke guide pipe being vertically arranged at the top of the carbonization chamber.

[0041] The cleaning mechanism is arranged on the connecting frame 2, and is used for extending into the smoke guide pipe after the furnace cover is lifted, and cleaning the inside of the smoke guide pipe.

[0042] Exemplarily, when the smoke pipe needs to be cleaned, the position of the connecting frame 2 on the track 1 can be adjusted first, so that the cover lifting mechanism 3 moves to a suitable position with the connecting frame 2, for example, the cover lifting mechanism 3 is located directly above the smoke pipe. Then the furnace cover is lifted by the cover lifting mechanism 3, so that the furnace cover is separated from the smoke pipe. Then the position of the connecting frame 2 on the track 1 is adjusted again, so that the cover lifting mechanism 3 and the lifted furnace cover are staggered with the smoke pipe, and the cleaning mechanism is located above the smoke pipe. Then the cleaning mechanism enters the smoke pipe to clean the smoke pipe. For example, the graphite dust accumulated on the inner wall of the smoke pipe and / or the smoke pipe can be cleaned, so that the graphite dust accumulated on the inner wall of the smoke pipe and / or the smoke pipe can be separated from the smoke pipe, thereby solving the problem of smoke pipe blockage. When the smoke pipe is cleaned, the cleaning mechanism is removed from the smoke pipe. Then continue to adjust the position of the connecting frame 2 on the track 1, so that the cover lifting mechanism 3 returns to the top of the smoke pipe again, and the cover lifting mechanism 3 puts the furnace cover down and returns it to its position. The smoke guide vehicle can move between the various smoke guide pipes in the carbonization chamber to clean all the smoke guide pipes in the carbonization chamber of the coke oven.

[0043] After the cover lifting mechanism 3 lifts the furnace cover of the smoke guide pipe, the smoke guide pipe of the carbonization chamber is automatically cleaned by extending the cleaning mechanism into the smoke guide pipe, thereby avoiding the problems of high labor intensity, high safety hazards in the working environment and poor cleaning effect caused by manual cleaning.

[0044] In some embodiments, the cover lifting mechanism 3 may be an electric hoist, and the free end of the wire rope of the electric hoist is provided with a hook, which is used to hook on the furnace cover to lift and lower the furnace cover. For example, a lifting position for hanging the hook may be provided on the top of the furnace cover. When the cover lifting mechanism 3 moves to the top of the smoke guide tube, the electric hoist lowers the wire rope, and the hook can hook the furnace cover, and then the electric hoist winds the wire rope so that the wire rope can drive the furnace cover to move upward and away from the smoke guide tube. Of course, the end of the wire rope can also adopt a structural method of setting a magnet, and the magnet can be adsorbed on the furnace cover. When the cover lifting mechanism 3 moves to the top of the smoke guide tube, the electric hoist lowers the wire rope, and the magnet can adsorb the furnace cover, and then the electric hoist winds the wire rope so that the wire rope can drive the furnace cover to move upward and away from the smoke guide tube.

[0045] In some embodiments, the cleaning mechanism includes a shaft 9 , a cleaning head 11 , and a pneumatic or hydraulic cylinder 4 .

[0046] The air cylinder or hydraulic cylinder 4 is arranged on the connecting frame 2, and one end of the shaft 9 is connected to the cleaning head 11, specifically, the lower end of the shaft 9 can be connected to the cleaning head 11. The other end of the shaft 9 is connected to the piston rod of the air cylinder or hydraulic cylinder 4, so that when the piston rod is extended, the drive shaft 9 and the cleaning head 11 move synchronously, so that the cleaning head 11 can enter the smoke guide pipe for cleaning. Because the smoke guide pipe has a certain temperature, the cleaning head 11 and the shaft 9 can be made of high temperature resistant materials to increase their service life. Of course, it can be understood that the air cylinder or hydraulic cylinder 4 in the cleaning mechanism can also be replaced by other power mechanisms, which is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0047] In some embodiments, the cleaning head 11 includes a scraper 12 and a spring 13, one end of the spring 13 is arranged on the shaft 9, and the other end of the spring 13 is arranged on the scraper 12. Specifically, the other end of the spring 13 is arranged on the non-blade side of the scraper 12. When the cleaning head 11 extends into the smoke guide tube, the scraper 12 is restricted by the inner wall of the smoke guide tube, and the spring 13 can be compressed so that the blade of the scraper 12 can always fit closely to the inner wall of the smoke guide tube, so that when the cleaning head 11 moves up and down in the smoke guide tube, the scraper 12 can relatively thoroughly clean the graphite smoke accumulated on the inner wall of the smoke guide tube. A plurality of scrapers 12 can be arranged circumferentially around the shaft 9 to improve the cleaning efficiency of the smoke guide tube.

[0048] Of course, the scraper 12 can also be an annular scraper 12 having an inner diameter equivalent to that of the smoke guide pipe, and the annular scraper 12 can be fixed on the shaft 9 .

[0049] In some embodiments, the cleaning head 11 includes at least two groups of scrapers 12, and the spring 13 includes an upper spring and a lower spring. The upper and lower parts of the scrapers 12 are connected to the shaft 9 through the upper spring and the lower spring, respectively, so that the scrapers 12 are relatively stably arranged on the shaft 9 to prevent the scrapers 12 from shaking when cleaning the inner wall of the smoke guide tube, thereby affecting the cleaning effect of the smoke guide tube. The scrapers 12 can be arranged parallel to the shaft 9, or at a certain angle to the shaft 9.

[0050] In some embodiments, the outer diameter of the upper end of the cleaning head 11 is greater than the outer diameter of the lower end of the cleaning head 11. The cleaning head 11 is in the shape of a cone that is larger at the top and smaller at the bottom. The cone angle range can be selected from 3° to 15°. On the one hand, this design method is to ensure that the cleaning head 11 can be smoothly placed in the smoke guide tube; on the other hand, it is to control the contact area between the cleaning head 11 and the inner wall of the smoke guide tube, and then control the friction between the cleaning head 11 and the inner wall of the smoke guide tube, so as to control the cleaning effect of the inner wall of the smoke guide tube according to production needs. That is, the friction between the scraper 12 and the inner wall of the smoke guide tube is moderate, which ensures the cleaning effect and the normal operation and service life of the cleaning device of the smoke guide tube of the carbonization chamber of the coke oven.

[0051] In some embodiments, the blade of the scraper 12 is serrated, and the serrated blade shape can better scrape off the graphite dust on the inner wall of the smoke guide pipe, thereby improving the cleaning effect. The scraper 12 can be made of a high-temperature resistant hard alloy material to increase its service life. The concave portion of the serrated blade can be used as a temporary storage space for the scraped graphite dust. In addition, the serrated design can ensure that the contact surface between the scraper 12 and the graphite dust layer is not too large, causing the scraper 12 to be subjected to excessive force exceeding the load of the motor 6.

[0052] In some embodiments, the cleaning mechanism further includes a motor 6 , a reducer 5 and a rotating sleeve 7 .

[0053] The motor 6 is arranged on the connecting frame 2 .

[0054] like Figure 2 As shown, the shaft 9 is provided with a guide member 10 protruding from the surface of the shaft 9, and the guide member 10 can be a long strip protrusion arranged along the axial direction of the shaft 9. Figure 3 As shown, a guide groove 8 is provided on the rotating sleeve 7 along its axial direction, which radially penetrates the side wall of the rotating sleeve 7, and the guide groove 8 is a long strip-shaped groove. The length of the guide groove 8 can be set according to the height of the smoke guide pipe, so that when the cleaning mechanism moves up and down, the guide member 10 can move up and down along the guide groove 8, and then the cleaning head 11 can clean the entire smoke guide pipe. That is, the length of the guide groove 8 corresponds to the up and down stroke of the cleaning mechanism. The rotating sleeve 7 is sleeved on the shaft 9, and the shaft 9 is coaxially arranged with the rotating sleeve 7. The length of the shaft 9 is greater than the length of the rotating sleeve 7. The guide member 10 is arranged in the guide groove 8, and when the shaft 9 moves up and down, the guide member 10 moves up and down along the guide groove 8, and the guide groove 8 realizes the guidance of the shaft 9 and the cleaning head 11. The guide member 10 cannot move along the circumferential direction of the rotating sleeve 7. The rotating sleeve 7 is connected to the motor 6 through the reducer 5, so that when the motor 6 drives the rotating sleeve 7 to rotate, because the guide member 10 cannot move in the circumferential direction of the rotating sleeve 7, the rotating sleeve 7 can apply a rotational force to the shaft 9 through the guide member 10 to drive the shaft 9 and the cleaning head 11 to rotate. That is, the cooperation between the guide groove 8 and the guide member 10 not only realizes the guiding effect on the shaft 9, but also has the function of power transmission. When the cleaning head 11 rotates, the smoke guide pipe can be cleaned in a rotational manner, further improving the cleaning effect of the smoke guide pipe. It can be understood that a plurality of parallel guide grooves 8 can be set on the rotating sleeve 7, and correspondingly, a guide member 10 that cooperates with the guide groove 8 is correspondingly set on the shaft 9. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0055] In some embodiments, the cleaning device for the smoke guide pipe of the coke oven carbonization chamber further comprises a driving mechanism, which is disposed on the smoke guide vehicle and connected to the connecting frame 2 to drive the connecting frame 2 to move along the track 1. The driving mechanism may be, but is not limited to, a cylinder or a hydraulic cylinder.

[0056] The actions of the lid lifting mechanism 3, the cleaning mechanism and the driving mechanism can be controlled by a control system (not shown in the figure), and the control system can be set in the electrical room of the smoke guide vehicle. The control system is installed in the original electrical room of the smoke guide vehicle, and the original electrical system of the smoke guide vehicle is used to add electrical components, including adding relevant control switches in the electrical control cabinet in the electrical room, and adding corresponding limit switches.

[0057] The embodiment of the utility model further provides a smoke guide vehicle, which includes a cleaning device for the smoke guide pipe of the carbonization chamber of the coke oven as described in any of the above embodiments. The track 1 in the cleaning device for the smoke guide pipe of the carbonization chamber of the coke oven is fixed on the smoke guide vehicle, and the smoke guide vehicle can move so that the cleaning device for the smoke guide pipe of the carbonization chamber of the coke oven can clean each smoke guide pipe of the carbonization chamber of the coke oven.

[0058] The cleaning device of the smoke guide pipe of the carbonization chamber of the coke oven in the embodiment of the utility model can be moved to the top of the smoke guide pipe of any carbonization chamber of the coke oven under the control of the smoke guide vehicle moving along the coke oven and its own movement, and complete the steps of removing the furnace cover, cleaning graphite, resetting the furnace cover, etc., to ensure the normal and stable production of the coke oven. The device adopts mechanized and automated means to replace manual cleaning, which reduces the personal operation risk in high temperature, toxic, flammable and explosive gas environment on the one hand; on the other hand, it improves the cleaning efficiency and cleaning degree and reduces the labor intensity.

[0059] The above describes in detail a number of embodiments of the present invention, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications to the embodiments based on the concept of the present invention, and these variations and modifications should all fall within the scope of protection claimed by the present invention.
