Description

Technical Field

[0001] This utility model relates to the field of coking equipment technology, and more specifically, to a ceramic liner configuration that is impact-resistant and damage-proof. Background Technology

[0002] In the field of coking equipment technology, equipment often faces complex and harsh working environments. For example, during the production, transportation, and related processing of coke, the internal components of the equipment are constantly subjected to frequent impacts and friction from materials such as coke. To protect the equipment and extend its service life, liners have become a key protective component. Traditional metal liners were one of the earliest and most widely used types of liners. However, while metal liners possess a certain degree of toughness and can withstand a certain level of impact, they perform poorly in terms of wear resistance. Due to the high hardness of coke, the metal liners wear down rapidly during long-term contact, collision, and friction. This not only significantly shortens the liner's service life, requiring frequent replacements and increasing equipment maintenance costs and downtime, but also damages the equipment itself due to the decreased protective performance of the liner after wear, affecting the normal operation and production efficiency of the entire coking equipment.

[0003] With the development of materials technology, ceramic liners have gradually gained application due to their high hardness and good wear resistance. However, most existing ceramic liner designs cannot effectively disperse and buffer impact forces. When materials impact the liner, the impact force often concentrates in a localized area, causing excessive stress on the liner in that area. This localized stress concentration accelerates liner damage and reduces its overall performance and service life. Moreover, due to the lack of a reasonable design, the liner cannot evenly distribute the impact force over a larger area when subjected to impact, resulting in the liner's protective effectiveness not being fully realized.

[0043] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this 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 Figure 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 transferred 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 liner is subjected to external impact, vibration or other external forces, there will be a tendency for relative movement between the liner body 1 and the conical ceramic column 2. The mechanical locking structure formed by the annular groove structure and the bearing ring edge of the positioning hole wall can effectively limit this relative displacement. The bearing ring edge is embedded in the annular groove. When there is an external force that causes the conical ceramic column 2 to come out of the positioning hole or to move laterally in the positioning hole, the bearing ring edge and the side wall of the annular groove block each other. The bearing ring edge will exert a reaction force on the side wall of the annular groove, thereby offsetting the external force that causes the conical ceramic column 2 to move. This allows the conical ceramic column 2 to be stably kept in the positioning hole of the liner body 1, maintaining the stability of the overall structure of the liner.

[0055] In high-impact environments, such as high-speed material impacts, the mechanical locking structure ensures that the conical ceramic column 2 will not detach from the positioning hole due to impact force. This guarantees that the conical ceramic column 2 can always disperse the impact force, preventing local protection failure due to the detachment of the conical ceramic column 2, thereby improving the overall impact resistance and reliability of the liner. During equipment operation, vibrations are often generated. The mechanical locking structure can also effectively resist the effects of vibration, preventing relative displacement and loosening between the conical ceramic column 2 and the liner body 1 during vibration. This helps maintain the integrity of the internal structure of the liner, reduces component wear and damage caused by vibration, and extends the service life of the liner.

[0056] The tapered ceramic column 2 has a spherical outer contour structure 3 at one end away from the liner body 1, which can be decomposed 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 disperses the concentrated impact force along its tangential direction. Compared to a planar structure, the spherical surface prevents the impact force from concentrating at a single point or in a small area, instead distributing it evenly over a larger area. This significantly reduces the impact force per unit area, effectively minimizing the possibility of the conical ceramic column 2 cracking or being damaged due to concentrated impact force, thus enhancing the impact resistance of the conical ceramic column 2 and the entire liner. The contact between the spherical outer contour and the impacting object is relatively smooth, resulting in a lower coefficient of friction compared to planar or sharp structures. A lower coefficient of friction means less frictional force is generated during impact and friction, reducing wear caused by friction and further improving the wear resistance of the liner.

[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 supports provide additional support and fixation for the conical ceramic columns 2. Under impact, vibration, or other external forces, they restrict the displacement of the conical ceramic columns 2, similar to how mechanical locking structures restrict the relative displacement between the liner body 1 and the conical ceramic columns 2. The horizontal and vertical supports ensure that the conical ceramic columns 2 are stably embedded in the positioning holes. Even in high-impact environments, such as high-speed material impacts, they prevent the conical ceramic columns 2 from loosening or falling off due to impact force, ensuring the integrity and stability of the liner structure and maintaining the overall stability of the liner structure, similar to how mechanical locking structures improve the reliability of the liner. The horizontal and vertical supports are distributed on the back of the liner body 1, serving to strengthen the structure. Under external forces, they resist the deformation of the liner, keeping it flat, which is crucial for the liner's protective performance, as deformation can affect its normal use and protective effect, similar to how mechanical locking structures help maintain the integrity of the liner's internal structure. The spherical outer contour structures 3 on the multiple conical ceramic columns 2 are all located in the grooves at the front of the liner body 1. This layout concentrates the protection focus on the front of the liner, better resisting the impact of external objects. The grooves can provide some protection for the spherical outer contour structure 3, while guiding the distribution of impact force, so that the impact force acts more evenly on each conical ceramic column 2, just like the principle of the spherical outer contour structure 3 dispersing impact force, thus improving the protection efficiency.

[0061] The positioning hole of the liner body 1 is a tapered hole with a diameter that gradually decreases from the outside to the inside, and the diameter of the tapered ceramic column 2 gradually decreases from the end away from the positioning hole to the end that is embedded in the positioning hole.

[0062] During installation, the conical hole and conical ceramic column 2 are designed for automatic centering. Since both have gradually changing diameters, when the conical ceramic column 2 approaches the positioning hole, it naturally slides down the inner wall of the hole to the appropriate position, eliminating the need for complex positioning operations, thus improving installation efficiency and reducing the performance degradation of the liner caused by inaccurate installation. As the conical ceramic column 2 gradually embeds into the conical hole, an increasingly tight fit is formed between them. Under the impact of falling coke, this tight fit effectively transfers the impact force from the conical ceramic column 2 to the liner body 1, and then distributes it across the entire bottom structure of the coke oven, avoiding localized stress concentration and improving the liner's impact resistance and overall structural stability. The conical structure makes it more difficult for the ceramic column to detach from the positioning hole when subjected to upward impact. The impact force increases the friction between the ceramic column and the positioning hole, further strengthening the connection and ensuring the long-term stable use of the liner under high-impact environments.

[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.

[0064] Example 3:

[0065] like Figures 1-5 As shown, the manufacturing process for producing the aforementioned impact-resistant and damage-resistant ceramic liner configuration includes the following steps:

[0066] Step S1: Making the white mold for the lost foam casting:

[0067] The lost foam white mold of the liner body 1 is made of EPS+PMMA copolymer beads;

[0068] A tapered positioning hole is machined on the white mold. The upper diameter of the tapered positioning hole is 22mm and the lower diameter is 18mm.

[0069] A bearing ring is machined along the wall of the tapered positioning hole;

[0070] Step S2, Ceramic column pretreatment:

[0071] The conical ceramic column 2 is machined using ZTA20 ceramic, and an annular groove structure with a depth of 0.3 mm and a width of 0.5 mm is machined at the root of the conical ceramic column 2.

[0072] Grind the spherical outer contour structure 3 at the end of the ceramic column 2 away from the root;

[0073] The ceramic column 2 was preheated at 850℃ to relieve stress;

[0074] Step S3, Inlaying, Positioning, and Sealing:

[0075] Embed the conical ceramic column 2 into the conical positioning hole of the white mold, so that the annular groove structure is aligned with the edge of the bearing ring;

[0076] Fill the gap between the conical ceramic column 2 and the conical positioning hole of the white mold with adhesive curing liquid, and form a sealed interface after curing;

[0077] Step S4, Application of thermal shock resistant coating:

[0078] The thermal shock resistant coating is dipped into the surface of the white mold and then dried in stages to form a thermal shock resistant coating.

[0079] Step S5, Dry Sand Molding and Pouring:

[0080] The white mold was filled with 4070 mesh abrasive and compacted by vertical vibration under a vacuum of 0.05 MPa.

[0081] Then, molten steel was poured in at a temperature of 1580±20℃ to obtain the liner body casting 1.

[0082] Step S6, Post-processing enhancement:

[0083] The liner body casting 1 is subjected to solution aging heat treatment, and the gaps in the matrix are filled with ramming material. After curing with aluminum dihydrogen phosphate binder, the impact-resistant and damage-resistant ceramic liner configuration is obtained.

[0084] The raw materials in the thermal shock resistant coating are as follows by percentage: 70% zircon powder, 5% nano-zirconia, 3.5% sodium bentonite, and 21.5% high-temperature adhesive. The 21.5% high-temperature adhesive is one or a combination of silicate adhesives, silicone resins, and ceramic-based adhesives.

[0085] The working principle and technical effects of the above scheme are as follows:

[0086] In the manufacturing process of this utility model, EPS+PMMA copolymer beads are used to make the lost foam casting of the liner body. A conical positioning hole with an upper diameter of 22mm and a lower diameter of 18mm is pre-set in the white mold. The upper diameter of the conical positioning hole is 22mm to increase the wear-resistant area by 15% and more completely cover the wear trajectory. The lower diameter of the conical positioning hole is 18mm to reduce the amount of grooving in the white mold and maintain its strength. The conical structure reduces the peak thermal stress from 320MPa to 190MPa (based on finite element simulation results). This is due to the mechanical anchoring effect of the conical structure, which effectively improves the pull-out resistance and shear resistance. A bearing ring is machined along the hole wall to form a double-limiting structure to eliminate the displacement error of the ceramic column. ZTA20 ceramic is used to machine the conical column, with the root turned to a depth of 0.3mm and a width of 0.5mm. The annular groove has a ground spherical outer contour at the end, and is preheated at 850℃ to relieve stress and prevent vaporization at the casting interface. The spherical design increases the normal component of the impact force and reduces the shear force by 40%. The ceramic column is embedded in the conical hole of the white mold, and the annular groove is precisely aligned with the edge of the bearing ring. The gap is filled with aluminum dihydrogen phosphate adhesive (temperature resistance >1000℃), which forms a sealed interface after curing. The interface shear stress is controlled below 142MPa, and the thermal cycling peeling rate is <1%. The coating is dip-coated with a coating containing 70% zircon powder + 5% nano zirconium oxide + 3.5% sodium bentonite, with a viscosity of 45s (flow cup method). After step drying, a 1.2mm coating is formed. Nano zirconium oxide improves the toughness of the coating, reducing the peak thermal stress by 35% and the thermal shock life exceeds 800 cycles. 40-70 mesh abrasive is used for filling, and vertical vibration (acceleration 12m / s²) is applied. 2 (×3min) to make the density of sand around the ceramic column > 1.75g / cm³ 3The vacuum degree is -0.05MPa to maintain the rigidity of the sand mold, and the molten steel is poured at 1580±20℃. Finally, the casting is subjected to solution treatment at 1150℃ and aging heat treatment at 750℃. The matrix gaps are filled with ramming material containing 60% fused alumina, 25% recycled ZTA powder and 1.5% steel fiber. After curing at room temperature for 48 hours with aluminum dihydrogen phosphate binder, it is dried at 110℃ for 24 hours. This formula improves the high temperature strength and reduces the cold end temperature to 220℃.

[0087] In this invention, the diameter of the conical ceramic column 2 gradually decreases from the end furthest from the positioning hole to the end embedded in the positioning hole. The small root design of the conical ceramic column 2 reduces thermal expansion displacement by 35%, and combined with the nano-coating, the peak thermal stress reaches 1380MPa, with a safety factor of 1.92. The conical ceramic column 2 has good impact resistance, and the spherical contour guides the impact force. Under the impact of a 3m coke drop, the top of the sphere is undamaged, and the depth of the base pit is only 0.3mm. The structural design of the conical ceramic column 2 can reduce the coke slip angle to 22°, achieve an equivalent wear-resistant coverage of 94%, and improve the cost-effectiveness ratio by 45%.

[0088] The application is adapted to the aforementioned impact-resistant and damage-preventing ceramic liner configuration, which is installed in the high-impact zone at the bottom of a coke oven to reduce the impact damage of falling coke to the coke oven through a conical ceramic column 2 with a spherical outer contour structure 3.
