Description

Technical Field

[0001] This application belongs to the field of dry quenching technology, specifically relating to a coke pot for use in a dry quenching coke oven. Background Technology

[0002] Dry quenching is a coke quenching technology that uses inert gas to cool red-hot coke in a sealed system. It recovers heat energy by exchanging heat between circulating gas and high-temperature coke and converts it into steam for power generation. It has the advantages of energy saving, environmental protection and improved coke quality.

[0003] The coke can is a key piece of equipment in the dry quenching system for transporting high-temperature red coke. It can transport the high-temperature red coke from the carbonization chamber to the top of the dry quenching oven to complete the loading process. In the existing technology, the inner peripheral wall of the coke can is lined with plates, which can block the heat of the red coke. The side walls of adjacent plates are in contact with each other, and each plate has a connecting part that passes through the coke can and is fixed to the outside of the coke can through the connecting part.

[0004] Under prolonged alternation of hot and cold temperatures, uneven deformation at the edges of the lining can easily lead to the edges of the lining lifting up. Once the edges of the lining lift up, gaps will appear between adjacent lining sections, which can easily cause air leakage. Utility Model Content

[0005] This application provides a coke pot for a dry quenching coke oven, which aims to solve the problem of air leakage at the edge of the liner in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A coke pot for a dry quenching coke oven is provided, comprising: The tank body has several inner annular ribs spaced along the height direction on the inner circumferential wall, and several inner longitudinal ribs spaced along the circumferential direction on the inner circumferential wall. A placement groove is formed between two adjacent inner longitudinal ribs and two adjacent inner annular ribs. Several lining plates are provided, each corresponding to a placement slot; the lining plates are inserted into the placement slots at their corresponding positions, and a heat-insulating sealing plate is abutting between the lining plates and the inner peripheral wall of the tank. The bottom wall of the placement slot has a through groove that connects to the side wall of the tank, the heat insulation sealing plate has a relief groove corresponding to the through groove, and each of the liner plates has a connecting component that can extend out of the through groove. The connecting component is connected to the outer side wall of the tank through a fastener.

[0007] In one possible implementation, a heat-insulating sealing frame is provided between the outer peripheral wall of the liner and the inner peripheral wall of the placement groove, and the heat-insulating sealing frame is fixed on the heat-insulating sealing plate.

[0008] In one possible implementation, the connecting member has a connecting hole, the fixing member has a through hole aligned with the connecting hole, and the connecting member and the fixing member are fixed by bolts and nuts; The fastener spans the through groove, and its end has a threaded hole corresponding to the outer wall of the tank. A fixing bolt is provided on the threaded hole, and the threaded end of the fixing bolt abuts against the outer wall of the tank.

[0009] In one possible implementation, each of the liner plates has two connecting parts, and the number of fasteners is the same as the number of connecting parts; the two connecting parts are located at both ends of the tank through groove.

[0010] In one possible implementation, the connecting component has at least two connecting holes, and the fixing bolt is provided with a clamping nut; When the threaded end of the fixing bolt abuts against the outer wall of the tank, the tightening nut engages with the threaded bolt and abuts against the fixing component.

[0011] In one possible implementation, the outer peripheral wall of the tank is connected with a number of outer annular ribs and a number of outer longitudinal ribs, and a receiving groove is formed between two adjacent outer annular ribs and two adjacent outer longitudinal ribs; the extension of the connecting component and the fixing component are both located in the receiving groove.

[0012] In one possible implementation, each of the receiving slots corresponds to one of the placement slots, or each of the receiving slots corresponds to two adjacent placement slots.

[0013] In one possible implementation, the liner has a groove on the side near the inner peripheral wall of the tank, and the connecting component is connected to the groove.

[0014] In one possible implementation, the inner wall of the liner is an arc surface, and the inner side of the liner protrudes from the inner annular rib and the inner longitudinal rib.

[0015] In one possible implementation, the liner is connected to a stiffening plate within the groove, and the stiffening plate is connected to the connecting component.

[0016] This application provides a coke can for dry quenching coke ovens. Compared with the prior art, by setting inner annular ribs and inner longitudinal ribs on the inner side of the can, the inner side of the can can be divided into several placement slots, making it convenient to place each liner in the corresponding placement slot. By setting a heat-insulating sealing plate in the placement slot, after the position of the connecting parts is fixed by the fasteners, the liner and the inner peripheral wall of the can can clamp the heat-insulating sealing plate, improving the sealing performance. Through the above-mentioned settings of this application, the inner annular ribs and inner longitudinal ribs can separate two adjacent liners, and the sealing effect between the heat-insulating sealing plate and the liner can improve the sealing performance and reduce the occurrence of air leakage.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figures 1 to 3This application describes a coke can for a dry quenching coke oven. The coke can includes a can body 1 and several liners 2. The inner circumferential wall of the can body 1 is provided with several inner annular ribs 3 spaced along its height, and several inner longitudinal ribs 4 spaced along its circumference. A placement groove is formed between two adjacent inner longitudinal ribs 4 and two adjacent inner annular ribs 3. Several liners 2 correspond one-to-one with the placement grooves. The liners 2 are inserted into the corresponding placement grooves, and a heat-insulating sealing plate 5 abuts against the inner circumferential wall of the can body 1. The bottom wall of the placement groove has a through groove communicating with the side wall of the can body 1. The heat-insulating sealing plate 5 has a clearance groove 51 corresponding to the through groove. Each liner 2 has a connecting component 21 that extends out of the through groove. The connecting component 21 is connected to the outer wall of the can body 1 via a fixing member 6.

[0021] This application provides a coke can for a dry quenching coke oven. Compared with the prior art, by providing inner annular ribs 3 and inner longitudinal ribs 4 on the inner side of the can body 1, the inner side of the can body 1 can be divided into several placement slots, making it convenient to place each liner 2 in the corresponding placement slot. By providing a heat-insulating sealing plate 5 in the placement slot, after the position of the connecting component 21 is fixed by the fastener 6, the liner 2 and the inner peripheral wall of the can body 1 can cooperate to clamp the heat-insulating sealing plate 5, improving the sealing performance. Through the above-mentioned configuration of this application, the inner annular ribs 3 and inner longitudinal ribs 4 can separate two adjacent liners 2, and the sealing effect between the heat-insulating sealing plate 5 and the liner 2 can improve the sealing performance and reduce air leakage. The heat-insulating sealing plate 5 is elastic and can be made of zirconium-containing ceramic fiber composite material to give the heat-insulating sealing plate 5 high temperature resistance and flexibility, which can buffer the deformation of the liner 2.

[0022] It should be noted that when the liner 2 in the prior art leaks air, flames will shoot outward from the leaking point in the tank 1, posing a safety hazard. Other structures not mentioned in this application regarding the coke tank are all prior art and will not be described further here.

[0023] By inserting the liner 2 into the placement groove, the outer peripheral wall of the liner 2 can contact the inner peripheral wall of the placement groove, thus limiting the liner 2 in both the circumferential and axial directions and reducing the space for disordered deformation of the liner 2 under alternating hot and cold conditions.

[0024] The heat insulation sealing plate 5 between the liner 2 and the inner wall of the tank 1 can block heat transfer; the heat insulation sealing plate 5 can buffer the deformation of the liner 2 through its own elasticity, reducing the occurrence of edge warping of the liner 2.

[0025] The connecting component 21 extends out of the through groove and is fixed to the outside of the tank body 1 by the fastener 6, which can make the liner 2 press against the heat insulation sealing plate 5 and reduce the occurrence of gaps between the liner 2 and the tank body 1.

[0026] In some embodiments, such as Figures 1 to 3 As shown, a heat insulation sealing frame 52 is provided between the outer peripheral wall of the liner 2 and the inner peripheral wall of the placement groove. The heat insulation sealing frame 52 is fixed on the heat insulation sealing plate 5. The material of the heat insulation sealing frame 52 is the same as that of the heat insulation sealing plate 5.

[0027] By setting a heat-insulating sealing frame 52 between the outer peripheral wall of the liner 2 and the inner peripheral wall of the placement groove, the fitting gap between the liner 2 and the placement groove can be further filled. At the same time, by utilizing the elasticity and heat insulation of the heat-insulating sealing frame 52, the deformation of the edge of the liner 2 can be absorbed, reducing the occurrence of gaps between the liner 2 and the placement groove, thereby reducing the occurrence of air leakage.

[0028] In some embodiments, such as Figures 1 to 3 As shown, the connecting component 21 has a connecting hole 22, and the fixing component 6 has a through hole aligned with the connecting hole 22. The connecting component 21 and the fixing component 6 are fixed by bolts and nuts. The fixing component 6 spans the through groove, and the end of the fixing component 6 has a threaded hole corresponding to the outer wall of the tank body 1. A fixing bolt 7 is provided on the threaded hole, and the threaded end of the fixing bolt 7 abuts against the outer wall of the tank body 1.

[0029] By making the fastener 6 span the through groove, the threaded holes at both ends of the fastener 6 can correspond to the outer peripheral wall of the tank body 1. When the bolts are threaded into the threaded holes on the fastener 6, the threaded ends of the bolts can be pressed against the outer peripheral wall of the tank body 1, thereby making the liner 2 press against the heat insulation sealing plate 5 and improving the sealing performance.

[0030] In some embodiments, such as Figures 1 to 3 As shown, each liner 2 has two connecting parts 21, and the number of fasteners 6 is the same as the number of connecting parts 21; the two connecting parts 21 are located at both ends of the through groove of the tank body 1.

[0031] By setting two connecting parts 21 on the liner 2 and placing the two connecting parts 21 at both ends of the through groove, and fixing the connecting parts 21 with the fastener 6, the liner 2 can be subjected to more uniform force, avoiding stress concentration caused by single-point fixing.

[0032] In some embodiments, such as Figures 1 to 3 As shown, there are at least two connecting holes 22 on the connecting component 21, and a tightening nut 71 is provided on the fixing bolt 7; wherein, when the threaded end of the fixing bolt 7 abuts against the outer wall of the tank body 1, the tightening nut 71 is threadedly engaged with the fixing bolt 7 and abuts against the fixing member 6.

[0033] By providing at least two connecting holes 22 on the connecting component 21, after the connecting component 21 and the fixing member 6 are fixed by bolts and nuts, the occurrence of the liner 2 rotating around the axis of the connecting hole 22 can be reduced, thereby improving the stability between the liner 2 and the fixing member 6.

[0034] Since the fastener 6 spans the through groove of the tank body 1, and the heat insulation sealing frame 52 and the placement groove circumferentially limit the liner 2, the occurrence of the liner 2 falling into the coke tank can be reduced.

[0035] In some embodiments, such as Figures 1 to 3 As shown, the outer peripheral wall of the tank 1 is connected with several outer annular ribs 8 and several outer longitudinal ribs 9, and a receiving groove is formed between two adjacent outer annular ribs 8 and two adjacent outer longitudinal ribs 9; the extension of the connecting component 21 and the fixing component 6 are both located in the receiving groove.

[0036] The outer annular rib 8 and outer longitudinal rib 9 on the outer side of the tank body 1 form a receiving groove. The depth of the receiving groove is greater than the radial length of the fastener 6 along the tank body 1, so the fastener 6 is completely located within the receiving groove; this provides protection for the connecting component 21 and the fastener 6. In addition, the outer annular rib 8 and outer longitudinal rib 9 can improve the overall strength of the tank body 1.

[0037] In some embodiments, such as Figures 1 to 3 As shown, each receiving slot corresponds to one of the placement slots, or each receiving slot corresponds to two adjacent placement slots.

[0038] Near the top of the tank 1, each receiving slot corresponds to one of the placement slots; in other positions, each receiving slot corresponds to two adjacent placement slots; in this embodiment, each receiving slot corresponds to two adjacent placement slots along the height direction.

[0039] The liner 2 in this application is smaller than the liner 2 in the prior art. Specifically, the size of the liner 2 in this application is half the size of the existing liner 2. Therefore, the liner 2 in this application can reduce manufacturing difficulty and improve processing accuracy during the production process. When it is necessary to replace one of the liner 2, this application can save materials compared to the prior art.

[0040] In some embodiments, such as Figures 1 to 3 As shown, the liner 2 has a groove 23 on the side near the inner circumferential wall of the tank body 1, and the connecting component 21 is connected to the groove 23; the inner wall of the liner 2 is an arc surface, and the inner side of the liner 2 protrudes from the inner annular rib 3 and the inner longitudinal rib 4; the liner 2 is connected to the rib plate 24 in the groove 23, and the rib plate 24 is connected to the connecting component 21.

[0041] By providing a groove 23 on the side of the liner 2 near the inner circumferential wall of the tank body 1, and by providing a reinforcing rib 24 in the groove 23, the connection between the connecting component 21 and the liner 2 can be improved, and the rigidity of the overall structure of the liner 2 can be improved. By making the inner sidewall of the liner 2 into an arc surface, the contact between the liner 2 and the coke can be made smoother. By protruding the inner side of the liner 2 from the inner annular rib 3 and the inner longitudinal rib 4, a certain space can be provided for the deformation of the inner side of the liner 2.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
