Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching coke ovens, in particular to a cleaning device for a water seal groove on a top of a dry quenching coke oven. Background Art

[0002] The water seal tank is a key equipment in the CDQ coke oven, usually installed above the roof of the CDQ coke oven. The purpose of the water seal tank is to seal the furnace mouth to prevent harmful and flammable gases in the furnace from escaping from the furnace mouth. Water is placed in the water seal tank and the water level is maintained at a certain height. The edge of the furnace cover is inserted into the water seal tank, and the water level pressure is used to seal the gas in the furnace to prevent gas overflow. During the operation of the water seal tank, coke powder will be deposited at the bottom of the water seal tank. Long-term deposition will cause the water to be unable to cool the inner wall of the bottom of the water seal tank. The continuous high temperature of the CDQ coke oven will burn through the inner wall of the bottom of the water seal tank. In order to avoid this situation, the operating personnel will regularly clean the coke powder deposited inside the water seal tank.

[0003] After searching, the utility model patent with the publication number of "CN217025854U" provides "an improved dry quenching coke oven top water seal tank". The utility model provides a coke powder cleaning box, a storage port, a scraper and a cross bar. When cleaning the coke powder at the bottom of the water seal tank, the coke powder cleaning box is first placed inside the outer tank, and then the handle is used to drive the coke powder cleaning box to slide on the inner wall of the outer tank. The scraper can effectively scrape the coke powder to the storage port for collection, thereby effectively improving the cleaning efficiency of the device.

[0004] However, when cleaning the coke powder deposited at the bottom of the water seal tank, the operator needs to manually push the coke powder cleaning box with a handle to complete the coke powder collection work, which is a very labor-intensive process. Especially when there is too much coke powder deposited at the bottom of the water seal tank, it becomes very difficult to manually push the coke powder cleaning box, and it may even be impossible to push it.

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1-5As shown, the utility model provides a cleaning device for a water seal groove on a top of a dry coke quenching furnace, comprising two groups of annular chutes 2 and a collecting bucket 9 distributed up and down and arranged back to back, the inner side of the annular chute 2 is fixedly connected to the outer wall of a water seal groove body 1, an outer toothed disc 3 is fixedly connected to the outer side wall of the water seal groove body 1 between the two groups of annular chutes 2, a sliding member 4 is connected to the inside of the annular chute 2, an L-shaped connecting seat 5 is connected to the side of the sliding member 4 away from the annular chute 2, a buckle seat 52 is fixedly connected to the upper surface of the L-shaped connecting seat 5 located above, a cross bar 6 is connected to the internal bolts of the buckle seat 52, one end of the cross bar 6 is fixedly connected to a connecting plate 61, two groups of elastic members 7 are connected to the lower surface of the connecting plate 61, a column 8 is connected to the lower side of the elastic member 7, a square plate 81 is fixedly connected to the lower surface of the column 8, and the collecting bucket 9 is fixedly connected to the outer wall of the water seal groove body 1. It is fixedly connected to the lower surface of the square plate 81, and the collecting bucket 9 is located inside the water seal tank body 1, one side of the L-shaped connecting seat 5 is fixedly connected to a fixing plate 51, one side of the two fixing plates 51 is detachably connected to a fixing frame 10, the inside of the fixing frame 10 is fixedly connected to a reduction motor 11, the upper end of the reduction motor 11 is connected to a main shaft 111 through a coupling, and the main shaft 111 and the fixing frame 10 are rotatably connected, the outer side of the main shaft 111 is fixedly connected to a gear 112, the gear 112 is meshed with the outer gear disc 3, the inside of the fixing frame 10 and on one side of the reduction motor 11 is fixedly connected to a battery 12, the top of the battery 12 is connected to a control box 13, the reduction motor 11 and the battery 12 are electrically connected, and the reduction motor 11 and the battery 12 are both electrically connected to the control box 13.

[0030] In the utility model, when the coke powder cleaning and collection work is in progress, the control box 13 controls the reduction motor 11 to drive the gear 112 to make a circular motion around the outer gear plate 3, and then indirectly drives the collection bucket 9 to clean and collect the coke powder inside the water seal tank body 1 through the L-shaped connecting seat 5, which not only improves the cleaning efficiency, but also ensures the continuity and stability of the coke powder cleaning and collection work;

[0031] When the L-shaped connecting seat 5 drives the collecting bucket 9 to rotate around the water seal tank body 1, the sliding member 4 continues to slide inside the annular slide groove 2, so that the collecting bucket 9 moves more smoothly; at the same time, the annular slide groove 2 also plays a role of limiting and guiding the sliding member 4;

[0032] The elastic member 7 can provide elastic force to the column 8, thereby indirectly providing squeezing force to the collecting bucket 9, ensuring that during the coke powder cleaning and collection process, the bottom wall of the collecting bucket 9 can fit with the inner bottom wall of the water seal tank body 1, thereby reducing the possibility of coke powder residue and cleaning leakage;

[0033] The fixing plate 51 and the fixing frame 10 are detachable, so that after the coke powder is cleaned, the fixing frame 10 and the fixing plate 51 can be easily disassembled, and the disassembled fixing frame 10 together with the components installed inside can be moved to another place, so as to prevent the reduction motor 11, the battery 12, and the control box 13 inside the fixing frame 10 from being subjected to the high temperature baking of the dry quenching coke oven top for a long time, which may cause the equipment components to be damaged or the performance to be degraded;

[0034] Because the reduction motor 11 is in a state of relative rotation with the water seal tank body 1 when in operation, an external power supply cannot be connected in this operating state. Therefore, a battery 12 is used to provide a stable power source for the reduction motor 11. The battery 12 is used to supply power to the reduction motor 11 to provide the required power, ensuring that the coke powder cleaning and collection work can proceed smoothly.

[0035] Furthermore, the sliding member 4 includes a central seat 41, which is fixedly connected to the surface of the L-shaped connecting seat 5, and rollers 42 are rotatably connected to both sides of the central seat 41 through short shafts, and the rollers 42 are slidably connected to the inside of the annular chute 2; the rollers 42 can slide smoothly inside the annular chute 2. The two sets of sliding members 4 are installed oppositely to each other to slide inside the annular chute 2, which not only ensures the stability of the sliding members 4 during movement, but also provides stable support for the remaining parts connected to the sliding members 4.

[0036] Furthermore, a side of the cross bar 6 away from the connecting plate 61 is fixedly connected to a limiting block 62, and the limiting block 62 abuts against a side of the buckle seat 52 away from the water seal tank body 1; when the collecting bucket 9 is placed inside the water seal tank body 1, the cross bar 6 needs to be fixedly connected to the buckle seat 52. The advantage of the limiting block 62 is that it saves the operator the time required to align the cross bar 6 and the buckle seat 52 when fixing them. When fixing, it is only necessary to abut the limiting block 62 against the side of the buckle seat 52 away from the water seal tank body 1, which can indirectly ensure that the collecting bucket 9 is in the correct position inside the water seal tank body 1, thereby improving the convenience and efficiency of operation.

[0037] Furthermore, the elastic member 7 includes a base 71, which is fixedly connected to the lower surface of the connecting plate 61, a slide bar 72 is fixedly connected to the lower end of the base 71, a sleeve 73 is slidably connected to the lower end of the slide bar 72, and the lower surface of the sleeve 73 is fixedly connected to the upper surface of the column 8, a spring 74 is sleeved on the outer side of the slide bar 72, the upper end of the spring 74 abuts against the lower surface of the base 71, and the lower end of the spring 74 abuts against the upper surface edge of the sleeve 73; the sleeve 73 forms an elastic structure with the base 71 through the spring 74. The elastic force of the spring 74 can ensure that during the coke powder cleaning and collection process, the lower surface of the collection bucket 9 always keeps in close contact with the inner bottom wall of the water seal tank body 1, effectively preventing the coke powder from leaking or missing during the cleaning process.

[0038] Furthermore, the top height of the column 8 is higher than the height of the overflow port on the water seal tank body 1; the height of the overflow port determines the height of the water level inside the water seal tank body 1. Since the elastic member 7 is installed above the column 8, as long as the top height of the column 8 is higher than the height of the overflow port, it can be ensured that when the collecting hopper 9 is cleaning and collecting coke powder, the water inside the water seal tank body 1 will not soak into the elastic member 7, thereby extending the service life of the elastic member 7.

[0039] Furthermore, both sides of the opening of the collecting bucket 9 are obliquely connected with side plates 91, and the side of the side plate 91 away from the collecting bucket 9 is attached to the inner wall of the water seal tank body 1; the side plate 91 can effectively guide the coke powder to flow into the collecting bucket 9 along the side plate 91, thereby improving the collection efficiency of the coke powder. In addition, the side of the side plate 91 away from the collecting bucket 9 is attached to the inner wall of the water seal tank body 1, ensuring that the coke powder will not overflow during the flow, thereby ensuring the effectiveness of the cleaning work. During the coke powder cleaning and collection process, the side plate 91 of the collecting bucket 9 is always attached to the inner wall of the water seal tank body 1, which can effectively scrape off the coke powder attached to the inner wall, while also reducing the generation of cleaning dead corners and improving the cleaning efficiency.

[0040] Furthermore, a mounting groove 92 is provided on the lower surface of the opening of the collecting bucket 9, and a scraper 93 is connected to the internal screws of the mounting groove 92, and the lower surface of the scraper 93 on the side away from the collecting bucket 9 is attached to the inner bottom wall of the water seal tank body 1; the scraper 93 is an integrated slope, and when the collecting bucket 9 moves, the scraper 93 can effectively scrape off the coke powder deposited on the bottom of the water seal tank body 1, and through the inclined ramp of the scraper 93 itself, the coke powder is smoothly guided to the inside of the collecting bucket 9, thereby realizing the connection between cleaning and collection.

[0041] Furthermore, the inner bottom surface of the collecting bucket 9 is wavy; this structure can effectively increase the deposition area of ​​coke powder inside the collecting bucket 9, and improve the collection efficiency of coke powder. When the coke powder enters the collecting bucket 9, as the collecting bucket 9 moves, the water inside the water seal tank body 1 flows, but the wavy bottom surface structure can make the coke powder deposit at a lower position, which is not affected by the impact of the water flow, thereby ensuring the stable deposition of coke powder and the durability of the collection effect, effectively preventing the coke powder from flowing out of the collecting bucket 9 again, and ensuring the smooth progress of the cleaning process.

[0042] Furthermore, a fixing groove 511 is formed through the surface of the fixing plate 51, and the upper and lower surfaces of the fixing frame 10 are fixedly connected with a threaded column 101, and the threaded column 101 is movably connected inside the fixing groove 511, and a nut 102 is provided on the outer thread sleeve of the threaded column 101, and the nut 102 abuts against the fixing plate 51; the fixing plate 51 and the fixing frame 10 are fixed by using the nut 102 to cooperate with the threaded column 101, which is convenient for disassembly and assembly.

[0043] Furthermore, a guide groove 512 is provided on the surface of the fixing plate 51 close to the fixing frame 10, and guide blocks 103 are fixedly connected to the upper and lower surfaces of the fixing frame 10 and on both sides of the threaded column 101, and the guide blocks 103 are slidably connected to the inside of the guide groove 512; when the fixing frame 10 and the fixing plate 51 are matched and installed, the guide block 103 can be inserted into the inside of the guide groove 512 on the corresponding side, making the installation faster, more accurate and more convenient.

[0044] Working principle: In the first step, when the coke powder deposited at the bottom of the water seal tank body 1 needs to be cleaned, the collecting bucket 9 is first placed inside the water seal tank body 1, and then the cross bar 6 connected thereto is placed inside the buckle seat 52, and fixed with bolts to ensure that the collecting bucket 9 and the L-shaped connecting seat 5 are in a fixed state;

[0045] The second step is to insert the fixing frame 10 between the two sets of fixing plates 51. At this time, the threaded column 101 will slide into the fixing groove 511. When installing the fixing frame 10, it is necessary to ensure that the installed gear 112 and the outer gear plate 3 are in a correct meshing state to ensure the smooth progress of subsequent operations.

[0046] Step 3: After the installation is completed, tighten the nut 102 to abut against the upper surface of the fixing plate 51;

[0047] The fourth step is to control the reduction motor 11 to operate through the control box 13. The reduction motor 11 drives the gear 112 on the outside of the main shaft 111 to rotate through the coupling. Since the gear 112 and the outer gear plate 3 are in a meshing state, the gear 112 and the outer gear plate 3 rotate relative to each other, which indirectly drives the L-shaped connecting seat 5 to perform a circular motion around the outer periphery of the water seal tank body 1, thereby driving the collecting bucket 9 to move inside the water seal tank body 1, and then collecting the coke powder deposited at the bottom of the water seal tank body 1 in the collecting bucket 9;

[0048] In this way, the use process of the cleaning device for the water seal groove on the top of the dry coke quenching oven is completed, and the effective cleaning and collection of coke powder is achieved.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
