Description

Technical Field

[0001] The utility model belongs to the technical field of coking production equipment, and in particular relates to a mobile smoke guiding system for coal loading in a coke oven. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] At present, most coal coking production enterprises are mainly equipped with coke ovens, coal loading cars and coke pushers. The production process and layout are based on coke ovens as the main production body. Coke ovens are mainly used to complete coking operations. The middle position in front of the coke oven is the coal loading tower. The coal loading cars and coke pushers are located on both sides of the coal loading tower as the symmetrical center. In order to improve production efficiency, the coal loading car is only responsible for loading coal into the coke oven, and the coke pusher is responsible for removing and installing the furnace door in addition to pushing coke.

[0004] When the coal loading car is loading coal, the raw coal at room temperature will instantly generate a large amount of smoke when it encounters the furnace body at thousands of degrees, and part of the smoke will overflow the furnace hole. Part of the smoke overflowing the furnace hole will be absorbed by the smoke collection cover on the coal loading car, and part will be absorbed by the furnace head smoke collection cover installed on the upper part of the coke oven hole. However, when the coal loading car finishes loading and leaves, during the time interval when the coke pushing car drives from other furnace holes to the current furnace hole to install and close the furnace door, a large amount of smoke will be scattered everywhere, causing certain pollution to the atmosphere. In the prior art, there is no corresponding measure to solve the smoke scattered in the above time interval. Utility Model Content

[0038] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0039] Embodiment 1

[0040] In a typical implementation mode of the present utility model, as Figure 1-10 shown, a coke oven coal charging mobile smoke guide system is provided, including:

[0041] A smoke guide hood 5, the upper end of the smoke guide hood 5 is connected to the traveling mechanism 3 through a driving suspension frame 4, the traveling mechanism 3 moves within the suspension track 2, and the suspension track 2 is fixed on the furnace protection column of the coke oven through a suspension support beam 1;

[0042] A coal loading car, wherein a movable driving frame 7 is provided on the coal loading car. After the coal loading car is finished, it moves away from the furnace hole, and the movable driving frame 7 drives the smoke guide hood 5 to move closer to the furnace door by pushing the driving suspension frame 4;

[0043] The coke pushing car is provided with a fixed driving frame 6, and the coke pushing car is close to the furnace hole. The fixed driving frame 6 drives the smoke guide hood 5 away from the furnace door by pushing the driving suspension frame 4.

[0044] like Figure 1 As shown, the suspension support beam 1 is welded and fixed to the upper part of the furnace protection column with the help of the existing coke oven facility, and is used as a support. A suspension support beam is arranged every other furnace protection column. The suspension support beam can be made of H-shaped, channel steel, rectangular tube and other profiles. The suspension track is located at the front end position below the suspension support beam 1, and the connection method is welding. The direction of the suspension track 2 is set parallel to the coke oven. The structure of the suspension track 2 is as shown in FIG. Figure 6 As shown, H-beam, I-beam and other profiles can be selected as the moving running track.

[0045] like Figure 5 , Figure 6 and Figure 7 As shown, the running mechanism 3 serves as a running device moving along the suspension track 2, including a guide wheel 8 and a load-bearing running wheel 9 mounted on an assembly mounting seat 10. The guide wheel 8 is fixed by a steel structure welding bracket and fixed to the assembly mounting seat 10 with bolts. The guide wheels 8 are symmetrically installed and used in pairs, with their axes parallel to the middle web (vertical plate) of the track. The two guide wheels 8 clamp the middle web (vertical plate) of the track to play an anti-bias guiding role; the load-bearing running wheels 9 are fixed by a steel structure welding bracket and fixed to the assembly mounting seat 10 with bolts. They are symmetrically installed and used in pairs, with their axes parallel to the upper and lower wing plates (horizontal) of the track, and are located on the upper plane of the lower wing plate to play a role in bearing loads and running.

[0046] In this embodiment, two pairs of guide wheels 8 and two pairs of load-bearing running wheels 9 are provided, and the two pairs of load-bearing running wheels 9 are located between the two pairs of guide wheels 8 .

[0047] Furthermore, the suspension track adopts an H-shaped steel or I-shaped steel structure, and guide wheels 8 are symmetrically arranged on both sides of the middle web of the suspension track 2, and load-bearing running wheels 9 are symmetrically arranged on both sides of the middle web of the suspension track 2.

[0048] In this embodiment, the assembly mounting seat 10 is connected to the driving suspension frame 4 through two suspension hinge seats 11, wherein the suspension hinge seat 11 is composed of a welded support and a hinge pin, and the support is connected to the assembly mounting seat 10 with bolts. The assembly mounting seat 10 is a supporting seat for the integrated installation of all components of the running mechanism 3, and can be welded from steel plates or profiles.

[0049] As Figure 3 and Figure 4 shown, the driving suspension bracket 4, as the intermediate part connecting the suspension track 2 and the smoke guide hood 5, includes a C-shaped support frame 12 and a quick docking anti-reverse latch 13. The quick docking anti-reverse latch 13 is installed on the side of the C-shaped support frame 12 close to the coal charging car. Among them, the C-shaped support frame 12 is a C-shaped steel structure support frame welded by steel plates or profiled steel. Its first function is to connect and support the lower smoke guide hood 5, and the second function is to serve as the driving support frame of the moving smoke guide system. The quick docking anti-reverse latch 13 is used to complete the quick docking with the coal charging car and play a role in limiting the end of the movable driving frame on the coal charging car, so as to realize the driving and walking of the driving suspension bracket 4 by the coal charging car. The quick docking anti-reverse latch 13 is composed of a rotating block and an anti-reverse seat. The rotating block can only rotate in one direction. When rotating in the reverse direction, it is blocked and restricted by the anti-reverse seat. The quick docking anti-reverse latch 13 adopts an existing structure and will not be elaborated here. In order to simplify the structure, a simple limit pin can also be used as long as the corresponding function can be achieved.

[0050] As Figure 8 and Figure 9 shown, the smoke guide hood includes a steel structure frame 14. The outer surface of the steel structure frame 14 is riveted with a sealing plate 15. The steel structure frame 14 and the sealing plate 15 form an upward smoke guide channel. Elastic seals 17 are installed at the positions where the sealing plate 15 contacts the furnace protection columns on both sides of the furnace hole. Specifically, the steel structure frame 14 is a three-dimensional frame structure welded by stainless steel profiles, which can prevent deformation to the greatest extent; the sealing plate 15 is a relatively thin stainless steel plate riveted on the outer surface of the steel structure frame 14 (the surfaces facing the furnace hole and the upper part are not covered with steel plates, forming an upward smoke guide channel); on the side where the front part of the smoke guide hood 5 contacts the furnace protection columns on both sides of the furnace hole, a relatively dense wire member is installed as the elastic seal 17. This structure not only has the function of blocking smoke but also plays an elastic buffering role, avoiding mechanical damage caused by hard contact. The lifting lugs 16 are located above the smoke guide hood 5 and are used to connect with the hinge seats below the driving suspension bracket 4.

[0051] As Figure 2 and Figure 3 shown, the fixed driving frame 6 is fixed on the upper platform frame of the coke pusher. A fixed Y-shaped push rod is provided at the front end, which fits against the side of the driving suspension bracket 4 during movement to drive the entire smoke guide hood system to move; the movable driving frame 7 is fixed on the upper platform frame of the coal charging car. A movable Y-shaped push rod is provided at the front end. The Y-shaped push rod is driven by an oil cylinder or a cylinder to realize the extension and retraction of the push rod. When the Y-shaped push rod extends, it is limited by the quick docking anti-reverse latch 13.

[0052] As Figure 10As shown, an upper balance adjustment mechanism 19 is provided at the connection position between the driving suspension bracket 4 and the traveling mechanism 3, and a lower balance adjustment mechanism 20 is provided at the connection position between the driving suspension bracket 4 and the smoke guide hood 5.

[0053] Specifically, the upper balance support 18 is a support steel member connected to the assembly mounting seat 10 at the lower part of the traveling mechanism 3. The lower part of the upper balance adjustment mechanism 19 is connected to the driving suspension bracket 4. The upper part of the upper balance adjustment mechanism 19 is provided with a screw adjustment mechanism. The lower part of the adjustment screw contacts the upper balance support 18, and the adjustment and buffering of the upper center of gravity of the moving smoke guide system are realized by means of the support of the upper balance support 18.

[0054] The lower balance adjustment mechanism 20 is a mechanism for ensuring the balance and adjustment of the smoke guide hood 5. The upper part of the lower balance adjustment mechanism 20 is fixedly connected to the driving suspension bracket 4 as a whole, and a screw adjustment device is provided at the lower part, which can play the role of adjusting the center of gravity balance and also play a limiting role, ensuring that the smoke guide hood 5 can not only maintain stability during operation but also ensure its sealing effect.

[0055] The positional relationship among the smoke guide hood 5, the coal charging car, and the coke pushing car of the coke oven coal charging moving smoke guide system provided in this embodiment is as Figure 4 shown. The coal charging car and the coke pushing car are respectively located on both sides of the smoke guide hood 5. The working process and principle are as follows:

[0056] 1. The current state of the coke oven is that the A furnace hole of the furnace chamber is empty and waiting for coal charging. The coal charging car finishes loading coal under the coal tower and travels towards the A furnace hole. At this time, the movable drive frame 7 installed on one side of the coal charging car is in the extended state. When the coal charging car approaches the moving smoke guide system, the Y-shaped push rod contacts the quick docking anti-retreat clip 13 of the driving suspension bracket 4. The quick docking anti-retreat clip 13 rotates under the action of the Y-shaped push rod. When the Y-shaped push rod moves beyond the rotation radius of the quick docking anti-retreat clip 13, the quick docking anti-retreat clip 13 automatically drops to prevent the Y-shaped push rod from retreating in the reverse direction and avoid the phenomenon of unhooking during the movement. The moving smoke guide system moves to the position of the A furnace hole together with the coal charging car under the drive of the coal charging car;

[0057] 2. The coal charging car carries the moving smoke guide system to the position of the A furnace hole for coal charging. Since the movable drive frame 7 is installed on the outside of the coal charging car, when the coal charging car charges coal, it drives the moving smoke guide system to move to the other side of the A furnace hole. When the coal charging is completed, the coal charging car needs to quickly pull the smoke guide system back to the position of the A furnace hole to block the flue gas from escaping. At this time, the oil cylinder (or air cylinder) in the movable drive frame 7 acts, the Y-shaped push rod retracts, and the movable drive frame 7 is separated from the moving smoke guide system. The moving smoke guide system stays at the position of the A furnace hole, and then the coal charging car continues to travel back to the coal tower to load coal;

[0058] 3. The smoke guide hood 5 of the mobile smoke guide system and the furnace protection columns on both sides of the No. A furnace hole form a smoke guide channel with a box structure. The upper part of each furnace hole communicates with the furnace head smoke ventilation groove located at the furnace top. At this time, under the sealing effect of the smoke guide hood 5 and the negative pressure effect of the furnace head smoke ventilation groove, the soot generated after coal charging in the No. A furnace hole is inhaled into the furnace head smoke ventilation groove.

[0059] 4. When the coke pusher moves towards the No. A furnace hole to install the door at other furnace numbers, when the fixed drive frame 6 installed inside the coke pusher approaches the mobile smoke guide system, the Y-shaped push rod on the fixed drive frame 6 directly pushes the entire mobile smoke guide system away from the No. A furnace hole by pushing the drive suspension frame 4. Then the coke pusher performs the door installation work for the No. A furnace hole, and then the coke pusher moves towards other furnace holes to perform door removal and coke pushing operations. Thus, a complete process of coal charging and smoke guiding for the No. A furnace hole is completed.

[0060] Both the upper and lower parts of the drive suspension frame 4 are hinge connection structures. To avoid interference with the existing facilities of the coke oven, this component is made into a C-shaped structure. The offset of the center of gravity is a major problem of this structure. Under the action of its center of gravity, the drive suspension frame 4 will rotate downward around the upper hinge position, and at the same time cause the lower connection position to move towards the furnace protection column. In this way, during the movement, the upper part of the smoke guide hood will collide with and interfere with the furnace protection column, while the lower part will deviate from the furnace protection column due to the overall tilt, resulting in poor sealing and finally smoke leakage occurring here. The upper balance adjustment mechanism 19 is used to correct and adjust the offset of the center of gravity of the drive suspension frame 4.

[0061] Driven by the coal charging car or the coke pusher, the smoke guide hood 5 will shake due to speed changes. A large amplitude of shaking will also cause jamming, collision and even damage of the smoke guide hood. By using the adjustment and limiting functions of the lower balance adjustment mechanism 20, the smoke guide hood is always in a relatively balanced state and runs smoothly.

[0062] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
