On the one hand, it will affect the heat transfer efficiency in the furnace, resulting in energy waste and increased production costs. Due to the heat insulation effect of the attachments, the heat transfer performance of the furnace wall decreases, making it difficult to accurately control the temperature in the furnace, affecting product quality and production efficiency. On the other hand, with the continuous accumulation of attachments, the effective space in the furnace may be reduced, affecting the normal flow and reaction process of materials, and may even cause the furnace to be blocked, seriously affecting the continuity and stability of production.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] See also Figures 1 to 3As shown, an embodiment of the first aspect of the present invention provides a coke removal device, including a driving part 1, a connecting part 2 and a coke pushing head 3, the driving part 1 is fixedly arranged on the outer peripheral surface of a furnace shell 4, the furnace shell 4 is provided with a coke pushing channel 41 for making way for the coke pushing head 3, the first end of the connecting part 2 is connected to the driving part 1, the second end of the connecting part 2 extends into the coke pushing channel 41 and is connected to the coke pushing head 3, the driving part 1 is used to drive the connecting part 2 to move, so as to drive the coke pushing head 3 to move in the coke pushing channel 41 away from the driving part 1 through the connecting part 2, and the coke pushing head 3 is used to impact an attachment to destroy the stress structure of the attachment.

[0028] In this embodiment, the coke pusher 3 impacts the attachments on the furnace wall 5 under the action of the driving unit 1, which can destroy the stress structure of the attachments and cause the attachments to fall off, thereby achieving the purpose of cleaning the attachments stuck on the furnace wall 5. By cleaning the attachments stuck on the furnace wall 5, the heat insulation effect of the attachments can be avoided, ensuring that the heat transfer performance of the furnace wall 5 is not affected, thereby stabilizing the temperature in the furnace, improving product quality and production efficiency; at the same time, the coke pusher 3 continuously cleans the attachments stuck on the furnace wall 5, which can effectively prevent the accumulation of attachments, avoid reducing the effective space in the furnace and blocking the furnace body due to the accumulation of attachments, thereby ensuring the normal flow of materials and the continuous production.

[0029] Furthermore, the driving unit 1 can be a motor, a hydraulic cylinder, etc., as long as it can provide power for the coke pusher 3, and the present invention does not make specific limitations on this. The driving unit 1 is fixedly arranged on the outer peripheral surface of the furnace shell 4, which means that the driving unit 1 is outside the furnace body. In this way, it does not occupy the space in the furnace, and can be easily installed and maintained. As the external protection structure of furnaces such as dry quenching furnaces, metallurgical industrial furnaces, and chemical production furnaces, the furnace shell 4 mainly plays the role of providing stable support for various components in the furnace. At the same time, it can also block dangerous factors such as high temperature, high pressure, and corrosive gases in the furnace to prevent them from causing damage to the surrounding environment and operators.

[0030] Furthermore, in order to allow the coke pushing head 3 to smoothly extend into the furnace, a coke pushing channel 41 is provided on the furnace shell 4. The coke pushing channel 41 can form a channel connected to the furnace, and the channel is used to make way for the coke pushing head 3 to ensure that the coke pushing head 3 can pass smoothly. When the coke pushing device starts to work, the coke pushing head 3 moves into the furnace along the coke pushing channel 41 through the connecting part 2 under the action of the driving part 1. In this process, the coke pushing channel 41 will not hinder the movement of the coke pushing head 3, but provides a special channel for it, so that the coke pushing head 3 can smoothly reach the position in the furnace where the attachments need to be cleaned, thereby achieving the purpose of cleaning the attachments on the furnace wall 5 and ensuring the normal operation of the furnace.

[0031] Furthermore, the connecting part 2 can be in the form of a mechanical connecting rod or the like. One end of the connecting part 2 is connected to the output end of the driving part 1 by means of a coupling or other connecting device, and the other end is fixedly connected to the coke pushing head 3 by means of bolts, welding or the like. When the coke removal device starts to work, the driving part 1 starts and generates power, which is transmitted to the coke pushing head 3 through the connecting part 2. Driven by the connecting part 2, the coke pushing head 3 moves in the coke pushing channel 41 in a direction away from the driving part 1. As the coke pushing head 3 continues to move, it gradually approaches the attachments on the furnace wall 5 and hits the attachments at a specific speed and force. In this way, the stress structure of the attachments is destroyed, causing them to lose their original stability. Subsequently, under the action of factors such as gravity and airflow in the furnace, the attachments begin to loosen and gradually fall off. Finally, the fallen attachments can be discharged out of the furnace through the coke removal system of the furnace body or other methods, thereby achieving the purpose of cleaning the furnace wall 5. It can be understood that during the entire working process, the driving part 1 can adjust the moving speed, frequency and strength of the coke pushing head 3 according to actual conditions to adapt to different attachment cleaning requirements. At the same time, the design of the coke pushing channel 41 ensures that the coke pushing head 3 can work safely and stably inside the furnace shell 4 without interfering with the normal operation of the furnace body.

[0032] In some possible implementations of the present invention, see Figure 3 As shown, the focus pushing channel 41 is inclined downward in a direction from approaching the driving part 1 to away from the driving part 1 .

[0033] Further, with the furnace shell 4 as a reference, the driving part 1 is fixed to the outer peripheral surface of the furnace shell 4. The coke pushing channel 41 is a channel opened on the furnace shell 4, one end of which is close to the driving part 1 and the other end is relatively far away from the driving part 1. Starting from the end close to the driving part 1, as it extends in the direction away from the driving part 1, the height of the coke pushing channel 41 gradually decreases, forming a downward sloping trend.

[0034] In this embodiment, the coke pushing channel 41 is inclined downward from the direction close to the driving unit 1 to the direction away from the driving unit 1. On the one hand, when the coke pushing head 3 moves in the direction away from the driving unit 1 under the push of the driving unit 1, gravity plays an auxiliary pushing role to a certain extent, reducing the power required to be provided by the driving unit 1. On the other hand, the inclined channel reduces the friction between the coke pushing head 3 and the channel wall, thereby reducing the energy loss of the coke pushing head 3 during the movement process and improving the working efficiency of the coke pushing head 3. In addition, it should be noted that the coke pushing channel 41 inclined downward can make the furnace shell 4 more evenly stressed during the coke removal process. When the coke pushing head 3 hits the attachment, the reaction force generated will be transmitted to the furnace shell 4. If the coke pushing channel 41 is horizontal, this reaction force may be concentrated in a specific area, causing local stress concentration on the furnace shell 4 and affecting the stability of the furnace shell 4. The channel inclined downward can disperse the reaction force to different parts of the furnace shell 4, reduce local stress concentration, and enhance the overall stability of the furnace shell 4.

[0035] In some possible implementations of the present invention, see Figure 3 As shown, the end surface of the coke pushing head 3 that contacts the attached objects is parallel to the furnace wall 5.

[0036] Furthermore, the coke pushing head 3 is a component used to hit the attachments on the furnace wall 5 to destroy its stress structure. There is a specific end face in the coke pushing head 3, which is the part that directly contacts the attachments on the furnace wall 5 when the coke pushing head 3 is working. From a geometric point of view, when the coke pushing head 3 is close to the furnace wall 5, the end face that contacts the attachments has no angle with the plane of the furnace wall 5 no matter from which direction it is observed. In other words, the relative position relationship between the two in space is just like two pieces of paper placed in parallel.

[0037] In this embodiment, the end face of the coke pushing head 3 in contact with the attachment is parallel to the furnace wall 5, so that when the coke pushing head 3 hits the attachment, it can act on the entire contact surface with uniform force, ensuring that the attachment is subjected to the same impact force at all locations, thereby more effectively destroying the stress structure of the attachment and improving the cleaning effect. At the same time, since the end face is parallel to the furnace wall 5, the coke pushing head 3 can achieve maximum contact with the attachment when approaching the furnace wall 5, so that the coke pushing head 3 can give full play to its impact effect and thoroughly clean the attachment from the furnace wall 5. In contrast, if the end face is not parallel to the furnace wall 5, the contact area between the coke pushing head 3 and the attachment may be reduced, reducing the cleaning effect.

[0038] In some possible implementations of the present invention, see Figure 1 and Figure 2As shown, the coke removal device also includes a sealing portion 6, which is located at the connection between the driving portion 1 and the furnace shell 4; the sealing portion 6 includes a connecting piece 61 and a sealing joint 62, the connecting piece 61 is connected to the sealing joint 62, the sealing joint 62 is relatively fixed to the furnace shell 4, a packing seal 63 is arranged at a position close to the connecting piece 61 in the inner wall of the sealing joint 62, a retaining ring 64 is arranged at the bottom of the packing seal 63, and a pressure cover 65 is arranged at the top of the packing seal 63.

[0039] In this embodiment, the sealing portion 6 is located at the connection between the driving portion 1 and the furnace shell 4, which can effectively prevent the gas, dust, particles and other substances in the furnace from leaking out from the connection. For some industrial furnaces that need to operate under a specific atmosphere, such as metallurgical furnaces, chemical furnaces, etc., the presence of the sealing portion 6 can ensure the stability of the atmosphere in the furnace and ensure the smooth progress of the production process. For example, in some high-temperature metallurgical processes, a reducing atmosphere needs to be maintained in the furnace. If the seal is not good, air entering the furnace will destroy this atmosphere and affect the product quality. At the same time, it can also prevent harmful substances in the furnace from leaking into the surrounding environment, which plays a protective role in the health and safety of the operators. Some industrial furnaces will produce toxic and harmful gases or dust during operation. If there is no good seal, these substances may leak out and cause harm to the operators. By setting the sealing portion 6, this situation can be effectively prevented from occurring and safety risks can be reduced.

[0040] Furthermore, the connecting piece 61 is a component in the sealing part 6 that connects the driving part 1 and the sealing joint 62, and can be made of metal material so that it has a certain strength and rigidity and can withstand the power transmitted by the driving part 1 and the pressure applied by the sealing joint 62.

[0041] Furthermore, the sealing joint 62 is relatively fixed to the furnace shell 4, and can be fixed to the furnace shell 4 by welding, bolting, etc. The sealing joint 62 is used to provide an installation position for the packing seal 63, and cooperates with the connector 61 to achieve a sealing function.

[0042] Furthermore, the packing seal 63 can be made of a soft and elastic material, such as graphite, asbestos, polytetrafluoroethylene, etc., to fill the gap between the connector 61 and the sealing joint 62 to form a sealing barrier to prevent leakage of materials in the furnace. When there is relative movement between the connector 61 and the sealing joint 62, the packing seal 63 can adapt to this movement and maintain good sealing performance.

[0043] Further, the retaining ring 64 is arranged at the bottom of the packing seal 63 to prevent the packing seal 63 from sliding down or deforming when under pressure. The retaining ring 64 can be made of metal material to have a certain strength and rigidity to withstand the pressure of the packing seal 63.

[0044] Furthermore, the gland 65 is disposed on the top of the packing seal 63 to apply a certain pressure to the packing seal 63 so that the packing seal 63 is more closely fitted between the connector 61 and the sealing joint 62 to enhance the sealing effect. The gland 65 can also be made of a metal material to have a certain strength and rigidity to withstand the reaction force of the packing seal 63.

[0045] In some possible implementations of the present invention, see Figure 1 As shown, the connecting part 2 includes a connecting rod 21 and a reinforcing rib plate 22 . The driving part 1 drives the focus pushing head 3 to move through the connecting rod 21 . The reinforcing rib plate 22 is located at the connection between the connecting rod 21 and the focus pushing head 3 .

[0046] In this embodiment, the connecting rod 21 is the main transmission component, which is responsible for transmitting the power of the driving unit 1 to the coke pushing head 3, so that it can move in the coke pushing channel 41 and hit the attachment. The reinforcing rib plate 22 is arranged at the connection between the connecting rod 21 and the coke pushing head 3, which can significantly enhance the connection strength of this key part. For example, in the process of the coke pushing head 3 hitting the attachment, a large reaction force will be generated. The reinforcing rib plate 22 can effectively disperse these reaction forces to prevent the connection between the connecting rod 21 and the coke pushing head 3 from breaking or deforming. In addition, the reinforcing rib plate 22 can also improve the overall stability of the connecting part 2. During the operation of the coke removal device, the connecting rod 21 may be subjected to forces and vibrations from different directions. The reinforcing rib plate 22 can increase the rigid connection between the connecting rod 21 and the coke pushing head 3, reduce the shaking and displacement of the connection, ensure that the coke pushing head 3 can accurately hit the attachment, and improve the cleaning effect.

[0047] Furthermore, the connecting rod 21 can be a cylindrical long rod, one end of which is connected to the output end of the driving unit 1, and the other end is connected to the coke pushing head 3 for transmission. In practical applications, the power generated by the driving unit 1 is transmitted to the coke pushing head 3 through the connecting rod 21, so that the coke pushing head 3 can perform linear motion in the coke pushing channel 41, move toward the attachment on the furnace wall 5 and hit the attachment.

[0048] Furthermore, the reinforcing rib plate 22 located at the connection between the connecting rod 21 and the focus pushing head 3 can be made of high-strength metal plate, so that it has high strength and toughness, can withstand the reaction force generated when the focus pushing head 3 hits the attachment, and prevent the connection between the connecting rod 21 and the focus pushing head 3 from breaking or deforming due to excessive force.

[0049] In some possible implementations of the present invention, see Figure 1 As shown, the coke pushing head 3 includes a coke pushing plate 31 , and an anchoring nail 32 is provided on the side of the coke pushing plate 31 facing away from the connecting portion 2 , and the anchoring nail 32 is used to carry the casting material 33 .

[0050] In this embodiment, by arranging anchor nails 32 to carry the castable material 33 on the side of the coke pushing plate 31 away from the connecting part 2, a solid protective layer can be formed on the surface of the coke pushing head 3, thereby improving the overall strength and rigidity of the coke pushing head 3 and enabling it to better withstand impact force and friction force.

[0051] Further, the coke pushing plate 31 is the main part of the coke pushing head 3, and can be made of a material with certain strength and wear resistance. In practical applications, the coke pushing plate 31 directly contacts and impacts with the attachments on the furnace wall 5 to achieve the purpose of cleaning the attachments.

[0052] Furthermore, an anchoring nail 32 is provided on the side of the coke pushing plate 31 facing away from the connecting portion 2, that is, the side facing the attachment when the coke pushing head 3 is working. The anchoring nail 32 is a small protrusion fixed to the coke pushing plate 31, and can be made of a metal material, so that it has a certain strength and rigidity and can carry the castable 33. It should be noted that a plurality of anchoring nails 32 can be provided, and the lengths of the plurality of anchoring nails 32 can be different, which can be selected based on the application scenario, and the present invention does not specifically limit this.

[0053] Furthermore, the castable 33 may be composed of refractory materials, adhesives, etc., so that it has good high temperature resistance, wear resistance, corrosion resistance and other properties. In practical applications, after the anchoring nails 32 are fixed on the coke pushing plate 31, the castable 33 is smeared or poured on the side of the coke pushing plate 31 with the anchoring nails 32. The anchoring nails 32 can make the castable 33 firmly attached to the coke pushing plate 31 to prevent the castable 33 from falling off during the operation of the coke pushing head 3. Therefore, when the coke pushing head 3 is working, the castable 33 layer can directly contact the attached object, which plays a role in protecting the coke pushing plate 31 and enhancing the wear resistance and high temperature resistance of the coke pushing head 3.

[0054] In some possible embodiments disclosed in the present invention, a stroke sensor is provided at the output end of the driving unit 1 , and the stroke sensor is used to monitor the stroke change of the output end of the driving unit 1 in real time.

[0055] In this embodiment, the travel sensor continuously monitors the travel change of the driving part 1. When the coke pushing head 3 completes the coke pushing task, the travel data can accurately determine that the coke pushing operation has ended. This enables the control system to issue a return instruction in a timely manner, ensuring that the coke pushing head 3 starts the return action at the right time, avoiding unnecessary delays or early returns, and improving the operating efficiency of the entire coke removal device.

[0056] Furthermore, the travel sensor may be a photoelectric, magnetoelectric or inductive sensor, etc., which can convert the travel change of the output end of the driving unit 1 into an electrical signal, and transmit these signals to the control system of the focus removal device. The control system can determine whether the focus pushing head 3 has reached the predetermined focus pushing position, or whether the output power of the driving unit 1 needs to be adjusted to control the moving speed of the focus pushing head 3 by analyzing the travel data.

[0057] See also Figure 3 As shown, an embodiment of the second aspect of the present invention provides a dry quenching coke oven, comprising any one of the above coke discharge devices. The dry quenching coke oven comprises a cooling zone, and the upper part and the lower part of the cooling zone are both provided with coke discharge devices.

[0058] In this embodiment, coke discharge devices are provided at both the upper and lower parts of the cooling zone of the dry coke quenching oven, so that all-round cooling of the red coke can be achieved. After the red coke is loaded from the top of the dry coke quenching oven, it first exchanges heat with the cooling gas at the upper part of the cooling zone. At this time, the coke discharge device at the upper part can timely clean the coke powder and other substances that may be attached to the furnace wall 5, ensuring the smooth circulation of the cooling gas and improving the cooling efficiency. At the same time, the coke discharge device at the lower part of the cooling zone is also playing a role, further cooling and cleaning the red coke that continues to fall after preliminary cooling, ensuring that the red coke can be fully cooled to a predetermined temperature.

[0059] In the above embodiment, at least six coke discharge devices are respectively disposed at the upper part of the cooling zone and the lower part of the cooling zone, and the at least six coke discharge devices are evenly arranged along the circumferential direction of the dry quenching coke oven.

[0060] In this embodiment, at least six coke discharge devices are provided at the upper and lower parts of the cooling zone, and are evenly arranged along the circumferential direction of the dry coke quenching oven, so as to achieve full coverage of the cooling zone. When the red coke exchanges heat with the cooling gas in the cooling zone, these coke discharge devices can clean the furnace wall 5 from different angles to prevent the accumulation of attachments such as coke powder, thereby ensuring that the cooling gas can evenly flow through various parts of the red coke and improve the uniformity of cooling.

[0061] Furthermore, corresponding to the different sizes of dry quenching coke ovens, 6 to 8 coke discharge devices are preferably arranged at the upper and lower parts of the cooling zone.
