[0018] This application provides a coke can lid for sealing coke cans. The coke can lid includes a dust collection component, with the dust collection port surrounding the periphery of the lid body. This allows dust inside the coke can to enter the dust collection port as it escapes with the hot airflow from the gap between the coke can opening and the lid, facilitating dust collection and effectively reducing dust generation during coke can transport.

[0019] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case: Depend on Figure 1It is understood that this application provides a coke can cover, including a cover plate body 1 and a dust collection component 2 connected to the cover plate body 1. The dust collection component 2 is provided with a dust collection port 21, which surrounds the periphery of the cover plate body 1.

[0020] In the above scheme, since the cover plate body 1 is located above the mouth of the coke can during the transfer of red coke, the dust collection port 21 of the dust collection component 2 surrounds the periphery of the cover plate body 1. In this way, the dust collection port 21 of the dust collection component 2 also surrounds the periphery of the mouth of the coke can. When dust escapes from the gap between the mouth of the can and the coke can cover with the hot airflow, the dust will enter the dust collection port 21 along with the hot airflow, thus facilitating dust collection and effectively reducing dust generation during the transfer of red coke.

[0021] In some embodiments, the dust collection component 2 includes a dust collection plate 22, at least a portion of which surrounds the periphery of the cover plate body 1, and a first gap is provided between the dust collection plate 22 and the cover plate body 1, the first gap forming the dust collection port 21.

[0022] In the above scheme, the dust collection port 21 is formed by the first gap between the part of the dust collection plate 22 located on the periphery of the cover plate body 1 and the cover plate body 1. The structure is simple, and part of the dust collection port 21 is formed by the original structure of the cover plate body 1, which can reduce the use of materials and reduce production costs.

[0023] In some examples, at least a portion of the dust collection plate 22 forms a structure with an annular cross-section, the annular structure being arranged around the periphery of the cover plate body 1.

[0024] In some examples, the inheriting plate includes multiple arc-shaped plates, which are spaced apart along the circumference of the cover plate body 1, and each arc-shaped plate has a first gap with the cover plate body 1.

[0025] In some examples, the dust collection plate 22 can be connected to the cover plate body 1 by welding.

[0026] In other examples, the dust collection plate 22 can be connected to the cover plate body 1 by a screw and a nut. For example, a screw is fixedly provided on the cover plate body 1, and a corresponding through hole is provided on the dust collection plate 22. The screw passes through the through hole and the dust collection plate 22 is fixed to the screw by a nut.

[0027] In some other examples, the cover plate body 1 and the dust collection plate 22 are connected by a support member, with one end of the support member connected to the cover plate body 1 and the other end connected to the dust collection plate 22.

[0028] In some examples, to extend the service life of the coke oven lid and reduce deformation of the dust collection plate 22 during use, tie rods can be provided between the dust collection plate 22 and the cover body 1.

[0029] In some other embodiments, the dust collection port 21 can be a flat, arc-shaped pipe. The curvature of the port can match that of the cover plate body 1, so that the dust collection port 21 can fit snugly against the periphery of the cover plate body 1.

[0030] In some embodiments, a portion of the dust collection plate 22 is located on the side of the cover body 1 facing the coke can.

[0031] In the above scheme, part of the dust collection plate 22 is located on the side of the cover plate body 1 facing the coke can. When the coke can cover is placed on the coke can, the part of the dust collection plate 22 on the side of the cover plate body 1 facing the coke can is located on the periphery of the coke can. In this way, the gap between the can opening and the coke can cover is located inside the dust collection port 21, which improves the dust collection efficiency of the dust collection port 21 and prevents dust from escaping.

[0032] In some examples, the height of the dust collection plate 22 located on the side of the cover plate body 1 facing the coke can be 5cm, 10cm, etc.

[0033] In some other embodiments, the height of the dust collection plate 22 facing the coke can be the same as or slightly higher than the height of the cover plate body 1.

[0034] In some embodiments, the dust collection plate 22 is provided with an inclined portion 221, which is located on the side of the cover plate body 1 facing the coke can, and along the line connecting the cover plate body 1 and the coke can, the inclined portion 221 is inclined in a direction away from the cover plate body 1.

[0035] In the above scheme, along the line connecting the cover plate body 1 and the coke tank, the inclined portion 221 is inclined in a direction away from the cover plate body 1. This causes the diameter of the dust collection port 21 to gradually increase along the direction towards the coke tank. This increases the cross-sectional area of ​​the dust collection port 21, thereby increasing the dust collection area and improving dust collection efficiency.

[0036] It should be noted that the diameter of the dust collection port 21 gradually increases along the direction towards the coke canister, making the dust collection port 21 funnel-shaped. In this way, not only can the dust collection area be increased, but since part of the dust collection plate 22 is located on the side of the cover plate body 1 facing the coke canister, the funnel shape of the dust collection port 21 facilitates the coke canister cover to seal the coke canister, preventing the edge of the dust collection plate 22 facing the coke canister from colliding with the coke canister and deforming.

[0037] In some examples, the tilt angle of the inclined portion 221 can be 15°, 20°, 25°, 30°, 50°, etc.

[0038] In some other embodiments, the diameter of the dust collection port 21 remains unchanged along the axial direction of the cover body 1.

[0039] In some embodiments, the cover plate body 1 has a channel 24 on the side opposite to the coke tank, one end of the channel 24 is connected to the dust collection port 21, and the other end is connected to the dust outlet 25.

[0040] In the above scheme, a channel 24 is provided on the side of the cover plate body 1 facing away from the coke tank. The channel 24 connects the dust collection port 21 and the dust outlet 25, so as to facilitate the collection of dust from the dust outlet 25 and avoid dust from being stirred up.

[0041] In some examples, to enhance the dust collection effect, a fan can be installed at the dust outlet 25. The fan rotation speeds up the air flow, thereby increasing the suction force of the dust collection outlet 21 on the dust.

[0042] In some examples, the dust collection port 21 can be connected to an external pipeline to collect dust in a concentrated manner.

[0043] In other examples, a dust collection bag can be installed at the dust collection port 21 to filter dust.

[0044] In some embodiments, the dust collection plate 22 includes a cover portion 23, which is located on the side of the cover plate body 1 facing away from the coke tank. A second gap is provided between the cover portion 23 and the cover plate body 1, forming a channel 24, which communicates with the first gap. A dust outlet 25 is provided on the side of the cover portion 23 facing away from the cover plate body 1, which communicates with the channel 24.

[0045] In the above scheme, a second gap is provided between the cover portion 23 of the dust collection plate 22 and the cover plate body 1, forming a channel 24 through the second gap. The channel 24 has a simple structure, is easy to process, and has a large space to prevent blockage.

[0046] In some examples, the size of the second gap between the cover portion 23 and the cover plate body 1 can be 1cm, 2cm, 3cm, etc.

[0047] In some examples, a support member may be provided between the cover portion 23 and the cover plate body 1 to improve the stability of the connection between the cover portion 23 and the cover plate body 1.

[0048] In some other embodiments, multiple metal tubes can be provided on the side of the cover plate body 1 facing away from the coke can, with one end of the metal tube connected to the dust collection port 21 and the other end connected to the dust outlet 25.

[0049] In some examples, the dust outlet 25 can be a circular or square tube connected to the cover portion 23, or it can be directly mounted on the cover plate body 1. When connecting the tube, the cover portion 23 can have a through hole, with the tube connected to the side of the through hole facing away from the cover plate body 1. The tube can be connected to the cover plate body 1 by welding or other methods. To facilitate connection between the dust outlet 25 and components such as dust collection bags, a flange 251 can be provided at the dust outlet 25.

[0050] In some embodiments, the coke can cover also includes an explosion-proof structure 3 that penetrates the cover body 1.

[0051] The explosion-proof structure 3 is provided with an explosion-proof port 31, which is located on the side of the cover part 23 opposite to the cover plate body 1.

[0052] In the above scheme, the coke canister, as a container for storing or handling flammable and explosive substances, poses a risk of internal explosion. When an explosive mixture (such as combustible gas, dust, etc.) reaches its explosive limit concentration in a confined space, an explosion can easily occur if there is an ignition source such as an electric spark or high temperature. Installing an explosion-proof structure 3 on the coke canister lid, connecting the inside of the coke canister to the outside, can improve the safety performance of the coke canister.

[0053] In some examples, the explosion-proof port 31 may be equipped with an explosion-proof valve that automatically opens to release pressure when the pressure inside the coke pot exceeds a set value.

[0054] In some embodiments, the coke can cover also includes a guide frame 4, which is connected to the side of the cover portion 23 facing away from the cover plate body 1.

[0055] In the above scheme, by setting a guide frame 4 on the coke can lid, the balance of the coke can lid during hoisting can be improved, the coke can lid can be prevented from tilting, and the coke can can be sealed smoothly.

[0056] In some examples, the guide frame 4 is welded from profiles such as square tubes.

[0057] In some examples, the guide frame 4 can be integrally formed through processing techniques such as casting.

[0058] In some examples, the guide frame 4 can be welded to the cover portion 23.

[0059] In other examples, the guide frame 4 can be connected to the cover 23 by means of bolts or other components.

[0060] In some examples, the guide frame 4 is connected to the spreader frame, and the movement trajectory of the coke can lid is constrained by physical limits.

[0061] In some embodiments, there are multiple guide frames 4, which are evenly distributed around the circumference of the cover plate body 1.

[0062] In the above scheme, multiple guide frames 4 are evenly placed around the circumference of the cover plate body 1, which can provide a uniform lifting force to the coke can cover when the lifting tool lifts it, and prevent the coke can cover from tilting.

[0063] In some examples, the number of guide frames 4 can be 2, 3, 4, etc.

[0064] In some embodiments, the cover plate body 1 is provided with a heat insulation layer 11 on the side facing the coke can, and the heat insulation layer 11 is provided with a recess 111 on the side facing the coke can, the recess 111 being used to accommodate the mouth of the coke can.

[0065] In the above scheme, a recessed part 111 is provided in the insulation layer 11. In this way, when the coke can lid is sealed to the coke can, the can mouth can be embedded in the recessed part 111, which improves the tightness of the coke can lid and the coke can, improves the insulation effect, and reduces dust.

[0066] In some other embodiments, the coke can lid may be provided with a protrusion that is embedded inside the coke can when the coke can is sealed, thereby improving the tightness of the fit between the coke can lid and the coke can.
