Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coking equipment, in particular to a kind of impact-resistant anti-damage ceramic lining configuration and manufacturing process and application. BACKGROUND

[0002] In the technical field of coking equipment, the equipment often faces complex and harsh working environment. For example, in the production, transportation and related processing process of coke, the internal components of the equipment will continuously suffer frequent impact and friction of materials such as coke. In order to protect the equipment and prolong its service life, the lining becomes a key protective component. The traditional metal lining is the earliest widely used lining type, but the metal lining, although having certain toughness, can withstand a certain degree of impact force, but performs poorly in wear resistance. Since coke has high hardness, in the process of long-term contact, collision and friction with metal lining, the metal lining will quickly wear out, not only greatly shortening the service life of the lining, requiring frequent replacement, increasing the maintenance cost and downtime of the equipment, but also causing damage to the equipment body due to the decline of the protective performance of the worn lining, affecting the normal operation and production efficiency of the entire coking equipment.

[0003] With the development of material technology, ceramic lining has gradually been applied due to its high hardness and good wear resistance. However, the existing ceramic lining configuration design mostly cannot achieve effective dispersion and buffering of impact force. When the material impacts the lining, the impact force is often concentrated in a local area, causing the lining to bear excessive stress in the local area, and the local stress concentration will accelerate the damage of the lining, reducing the overall performance and service life of the lining. Moreover, due to the lack of reasonable configuration design, the lining cannot uniformly transmit the impact force to a larger area when impacted, resulting in the inability to fully exert the protective efficiency of the lining.

[0043] In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. ​​​​

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0045] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0046] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0047] Example 1:

[0048] like Figures 1-5 As shown, an impact-resistant and damage-resistant ceramic liner configuration includes: a liner body 1 and a plurality of conical ceramic pillars 2 embedded in a plurality of positioning holes in the liner body 1; the space between the conical ceramic pillars 2 and the positioning holes is filled with an adhesive curing liquid for forming a sealing interface, the adhesive curing liquid being aluminum dihydrogen phosphate adhesive liquid.

[0049] The working principle and technical effects of the above scheme are as follows:

[0050] When an external impact acts on the ceramic liner, it first contacts the conical ceramic pillars 2. Since multiple conical ceramic pillars 2 are dispersedly embedded in multiple positioning holes of the liner body 1, the impact energy is transmitted to the liner body 1 through these distributed ceramic pillars. Compared with a single flat liner, the structure of this invention allows the impact force to be dispersed over a larger area, avoiding excessive stress in local areas. Each conical ceramic pillar 2 can transmit and diffuse the impact force it receives to the surroundings, enabling the liner as a whole to resist the impact in a coordinated manner. The adhesive curing liquid filling the space between the conical ceramic pillars 2 and the positioning holes forms a sealing interface after curing, filling the tiny gaps between the conical ceramic pillars 2 and the positioning holes, preventing external media from entering the interior of the liner body 1, and reducing the risk of erosion or damage to the liner body 1. Furthermore, the adhesive curing liquid acts as an adhesive, firmly fixing the conical ceramic pillars 2 in the positioning holes of the liner body 1, enhancing the connection strength between the two, ensuring that the ceramic pillars will not loosen or fall off during the impact, and guaranteeing the stability of the liner structure.

[0051] Example 2:

[0052] like Figures 1-5 As shown, the tapered ceramic column 2 has an annular groove structure at one end embedded in the positioning hole; the annular groove structure is fitted with a bearing ring edge opened on the wall of the positioning hole to form a mechanical locking structure for limiting the relative displacement of the liner body 1 and the ceramic column 2. The depth of the annular groove structure is 0.3 mm and the width is 0.5 mm.

[0053] The working principle and technical effects of the above scheme are as follows:

[0054] When the lining plate is subjected to external impact, vibration or other external forces, the lining plate body 1 and the conical ceramic column 2 will tend to move relatively, and the mechanical locking structure formed by the cooperation of the annular groove structure and the bearing ring along the wall of the positioning hole can effectively limit this relative displacement. When there is an external force that causes the conical ceramic column 2 to move laterally or fall out of the positioning hole, the bearing ring along will block the side wall of the annular groove, and the bearing ring along will exert a counterforce on the side wall of the annular groove, thereby offsetting the external force that causes the conical ceramic column 2 to displace, so that the conical ceramic column 2 can be stably maintained in the positioning hole of the lining plate body 1, maintaining the stability of the overall structure of the lining plate.

[0055] In a high-impact environment, such as high-speed impact of materials, the mechanical locking structure can ensure that the conical ceramic column 2 does not fall out of the positioning hole due to impact force, ensuring that the conical ceramic column 2 can always play a role in dispersing impact force, avoiding local protection failure caused by the conical ceramic column 2 falling out, and thereby improving the impact resistance and reliability of the overall lining plate. During the operation of the equipment, vibration often occurs, and the mechanical locking structure can also effectively resist the effects of vibration, preventing the conical ceramic column 2 from moving relatively and loosening with the lining plate body 1 during vibration, which helps to maintain the integrity of the internal structure of the lining plate, reduces component wear and damage caused by vibration, and prolongs the service life of the lining plate.

[0056] The end of the conical ceramic column 2 away from the lining plate body 1 is provided with a spherical outer contour structure 3 that can decompose and guide the distribution of impact force.

[0057] When an external object impacts the spherical outer contour of the conical ceramic column 2, the spherical surface will disperse the concentrated impact force along the tangent direction of the spherical surface. Compared with a flat structure, the spherical surface will not concentrate the impact force on a point or a small area, but will uniformly transmit the impact force to a larger area, greatly reducing the impact force per unit area and effectively reducing the possibility of the conical ceramic column 2 breaking or being damaged due to concentrated impact force, thereby enhancing the impact resistance of the conical ceramic column 2 and even the entire lining plate. The contact between the spherical outer contour and the impacting object is relatively smooth, and the friction coefficient is smaller than that of a flat or sharp structure. Smaller friction coefficient means smaller friction force generated during impact and friction, thereby reducing wear caused by friction and further improving the wear resistance of the lining plate.

[0058] The liner body 1 is provided with multiple interlocking areas. Each interlocking area is provided with multiple rows of positioning holes in the horizontal direction or multiple columns of positioning holes in the vertical direction. The rear ends of multiple conical ceramic pillars 2 in the multiple rows of positioning holes are in contact with and cooperate with multiple rows of horizontal support bodies on the back of the liner body 1. The rear ends of multiple conical ceramic pillars 2 in the multiple columns of positioning holes are in contact with and cooperate with multiple columns of vertical support bodies on the back of the liner body 1. The spherical outer contour structure 3 on the multiple conical ceramic pillars 2 is located in the groove at the front of the liner body 1.

[0059] The liner body 1 is provided with multiple interlocking areas. In each interlocking area, multiple conical ceramic columns 2 are distributed with multiple rows of horizontal positioning holes or multiple columns of vertical positioning holes. When an external impact acts on the liner, the impact force first contacts the conical ceramic columns 2. Due to the multiple interlocking areas and the multiple rows and columns, the impact energy will be transmitted through the numerous distributed conical ceramic columns 2. The rear ends of multiple conical ceramic pillars 2 within the multi-row positioning holes contact and engage with multiple rows of horizontal supports on the back of the liner body 1. Similarly, the rear ends of multiple conical ceramic pillars 2 within the multi-row positioning holes contact and engage with multiple rows of longitudinal supports on the back of the liner body 1. This allows the impact force to not only be transmitted between the conical ceramic pillars 2 but also to be further dispersed over a larger area through the horizontal and longitudinal supports. Compared to structures with a single or a small number of conical ceramic pillars, this layout avoids excessive stress in localized areas, disperses the impact force over a larger area, and improves the overall impact resistance of the liner. The horizontal and longitudinal supports connect the individual conical ceramic pillars 2 into a cohesive whole. When a conical ceramic pillar 2 is impacted, it can transmit part of the impact force to other surrounding conical ceramic pillars 2 through the horizontal and longitudinal supports, enabling the liner to resist impacts more stably, enhancing its impact resistance stability, and further improving its impact resistance performance.

[0060] The horizontal and vertical support bodies provide additional support and fixation for the conical ceramic column 2, which can limit the displacement of the conical ceramic column 2 when subjected to impact, vibration or other external forces, just like the principle of the mechanical locking structure limiting the relative displacement of the lining body 1 and the conical ceramic column 2, the horizontal and vertical support bodies ensure that the conical ceramic column 2 is stably embedded in the positioning hole; even in a high-impact environment, such as high-speed impact of materials, it can prevent the conical ceramic column 2 from loosening or falling off due to impact force, ensuring the integrity and stability of the lining structure, maintaining the stability of the overall structure of the lining, just like the effect of the mechanical locking structure improving the reliability of the lining. The horizontal and vertical support bodies are distributed on the back of the lining body 1, which plays a role in strengthening the structure, and when subjected to external forces, they can resist the deformation of the lining, keeping the lining flat, which is crucial for the protection performance of the lining, because deformation may affect the normal use and protection effect of the lining, just like the role of the mechanical locking structure in maintaining the integrity of the internal structure of the lining. The spherical outer contour structure 3 on the plurality of conical ceramic columns 2 is located in the groove on the front of the lining body 1. This layout focuses the protection on the front of the lining, better coping with the impact of external objects. The groove can provide some protection for the spherical outer contour structure 3, while guiding the distribution of impact force, making the impact force more evenly act on each conical ceramic column 2, just like the principle of the spherical outer contour structure 3 dispersing the impact force, improving the protection efficiency.

[0061] The positioning hole of the lining body 1 is a conical hole with a diameter gradually decreasing from the outside to the inside, and the diameter of the conical ceramic column 2 gradually decreases from the end far from the positioning hole to the end embedded in the positioning hole.

[0062] During installation, the structure of the conical hole and the conical ceramic column 2 can achieve automatic centering, as both their diameters are gradually changing, when the conical ceramic column 2 approaches the positioning hole, it will naturally slide along the inner wall of the conical hole to the appropriate position, without the need for complex positioning operations, improving installation efficiency, while also reducing the problem of performance degradation of the lining due to inaccurate installation position; as the conical ceramic column 2 gradually embeds into the conical hole, a tighter fit will be formed between them; under the impact of the coke falling body, the tight fit can effectively transfer the impact force from the conical ceramic column 2 to the lining body 1, and then to the entire coke oven bottom structure, avoiding local stress concentration, thereby improving the impact resistance of the lining and the stability of the overall structure; the conical structure makes it more difficult for the ceramic column to be dislodged from the positioning hole when subjected to upward impact force, the impact force will increase the friction between the ceramic column and the positioning hole, further enhancing the connection strength between them, ensuring the long-term stable use of the lining in a high-impact environment.

[0063] The surface of the liner body 1 is coated with a thermal shock resistant coating, which can improve the thermal shock resistance, wear resistance and corrosion resistance of the liner, reduce the damage and replacement frequency of the liner, thereby reducing the maintenance cost and downtime of the equipment and improving production efficiency.

[0081] Then pouring liquid steel, temperature 1580±20℃, get the liner body 1 castings;

[0082] Step S6, post-processing strengthening:
