Description

Technical Field

[0001] The utility model belongs to the technical field of nano-crystalline plates, and particularly relates to a nano-crystalline plate with firm connection and a microcrystalline plate assembly thereof. Background Art

[0002] Nano-crystalline plates have been widely used in industrial sectors such as building materials, chemical industry, metallurgy, and mining. On many high-temperature equipment, microcrystalline plates are relatively ideal substitute materials for the working surface of refractory materials, having high wear resistance, acid and alkali corrosion resistance, and anti-caking properties that general refractory materials cannot achieve. Moreover, they have advantages such as extending the service life, reducing maintenance man-hours, improving production efficiency, and reducing product costs.

[0003] In modern industrial production, industrial kilns are widely used in industries such as cement, steel, non-ferrous metallurgy, and petrochemical industry. Industrial kilns are generally used in high-temperature occasions. Several nano-crystalline plates are spliced together and then welded to the metal shell through heat-resistant steel anchor bolts. After that, casting materials are poured between the nano-crystalline plates and the metal shell. At present, the connection between the nano-crystalline plates and the casting materials is not firm enough, and it is extremely easy to fall off from the casting materials, resulting in a short service life of the industrial kiln, and it is easy for the adjacent nano-crystalline plates to be unevenly spliced after long-term use. Summary of the Utility Model

[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of the utility model is to provide a nano-crystalline plate with firm connection and a microcrystalline plate assembly thereof, which have better connection strength, the adjacent nano-crystalline plates are flatter, and further improve the service life of the industrial kiln.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A nano-crystalline plate with firm connection, including: a microcrystalline plate main body and a central fixing member. The lower end of the central fixing member is connected to the upper end of the microcrystalline plate main body. At least one tooth-shaped groove is respectively formed on the four side walls of the central fixing member, and the tooth-shaped groove is recessed towards the center of the central fixing member. The microcrystalline plate main body is provided with a matching groove part and flange part, and the groove part and the flange part are arranged diagonally on the microcrystalline plate main body.

[0007] The specific technical effect is that the adjacent two microcrystalline plate main bodies are mutually embedded and spliced through the groove part and the flange part, which not only improves the convenience of paving the microcrystalline plate main body, but also makes the integrity of the microcrystalline plate assembly better. By arranging the central fixing member on the microcrystalline plate main body, the microcrystalline plate main body can better fit on the casting material body, and by opening the tooth-shaped groove, the connection strength with the casting material body is increased, so that the connection between the central fixing member and the casting material body is more firm.

[0008] Furthermore, the two side walls of the tooth-shaped groove are V-shaped, and there is an included angle α between the two side walls of the tooth-shaped groove, and the range of the included angle α is 110° to 130°.

[0009] The specific technical effect is that without affecting the stability of the central fixing member itself, the two side walls of the tooth-shaped groove are designed in a V shape, and the included angle α ranges from 110° to 130°, so that the casting material can be poured into the tooth-shaped groove, thereby making the combination with the central fixing member more firm, increasing the holding force of the central fixing member, and making the main body of the microcrystalline board have better connection stability.

[0010] Furthermore, the projection distances of the two side walls of the tooth-shaped groove in the vertical direction are equal.

[0011] Furthermore, the tooth-shaped grooves on two adjacent side walls of the central fixing member are arranged staggeredly.

[0012] The specific technical effect is that the staggered arrangement design ensures more uniform connection between the periphery of the central fixing member and the casting material.

[0013] Furthermore, the main body of the microcrystalline board includes a lower bottom plate and an upper bottom plate, the lower bottom plate and the upper bottom plate are arranged in a staggered manner, the four side surfaces of the lower bottom plate and the four side surfaces of the upper bottom plate are not in the same plane, the front and rear two side surfaces of the upper bottom plate protrude forward relative to the front and rear two side surfaces of the lower bottom plate, and the left and right two side surfaces of the upper bottom plate protrude to the right relative to the left and right two side surfaces of the lower bottom plate.

[0014] The specific technical effect is that adjacent main bodies of the microcrystalline board are mutually engaged and spliced through a groove part and a flange part, so that when the four sides of the main body of the microcrystalline board are respectively spliced with adjacent main bodies of the microcrystalline board, a bent gap is formed between the two main bodies of the microcrystalline board. Compared with a linear gap, the bent gap has the effect of changing the direction of high-temperature heat flow, and the high-temperature heat flow cannot directly contact the casting material through the gap, further improving the service life of the industrial kiln.

[0015] Furthermore, the central fixing member is arranged in the middle of the upper end surface of the upper bottom plate, and the lower bottom plate, the upper bottom plate and the central fixing member are integrally formed.

[0016] The specific technical effect is that the integrally formed design reduces the assembly process and improves the structural strength and integrity of the microcrystalline board.

[0017] Furthermore, the main body of the microcrystalline board adopts an anti-crusting and super wear-resistant nano-microcrystalline board.

[0018] The specific technical effect is that it has a good anti-crusting effect, and it also has excellent hardness, thermal stability, high strength, wear resistance and corrosion resistance.

[0019] Further, a connection hole for the steel bar to pass through is respectively provided at the upper end and the lower end of the central fixing member.

[0020] The specific technical effect is that the steel bars pass through the connection holes at the upper end and the lower end of the central fixing member, and can be welded to the metal shell through heat-resistant steel anchor fittings. The connection and positioning are carried out through the steel bars, which improves the integrity of the main body of the microcrystalline board and enhances the bonding strength and stability between the main body of the microcrystalline board and the castable.

[0021] A microcrystalline board assembly, comprising a plurality of steel bars and a plurality of nano-microcrystalline boards as described in any one of the above. The plurality of nano-microcrystalline boards are laid and joined together through the groove part and the flange part, and each row of a plurality of the nano-microcrystalline boards joined together in the length direction is connected by two of the steel bars.

[0022] The beneficial effects of the present utility model are as follows:

[0023] (1) The adjacent two main bodies of the microcrystalline boards are mutually engaged and spliced through the groove part and the flange part, which not only improves the convenience of paving the main bodies of the microcrystalline boards, but also makes the integrity of the microcrystalline board assembly better;

[0024] (2) By arranging the central fixing member on the main body of the microcrystalline board, the main body of the microcrystalline board can be better attached to the castable, and by providing the toothed groove, the connection strength with the castable is increased, so that the connection between the central fixing member and the castable is more firm.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figures 1 to 6 shown, a nano-microcrystalline plate with firm connection, including a microcrystalline plate body 1 and a central fixing member 2. The lower end of the central fixing member 2 is connected to the upper end of the microcrystalline plate body 1. At least one tooth-shaped groove 3 is respectively opened on the four side walls of the central fixing member 2. The tooth-shaped groove 3 is recessed towards the center of the central fixing member 2. A groove portion 4 and a flange portion 5 that match each other are provided on the microcrystalline plate body 1. The groove portion 4 and the flange portion 5 are arranged diagonally on the microcrystalline plate body 1.

[0037] It should be noted here that: adjacent two microcrystalline plate bodies 1 are mutually embedded and spliced through the groove portion 4 and the flange portion 5, which not only improves the convenience of paving the microcrystalline plate body 1, but also makes the integrity of the microcrystalline plate assembly better. By providing the central fixing member 2 on the microcrystalline plate body 1, the microcrystalline plate body 1 can better fit on the casting material, and by opening the tooth-shaped groove 3, the connection strength with the casting material is increased, making the connection between the central fixing member 2 and the casting material more firm.

[0038] The two side walls of the tooth-shaped groove 3 are V-shaped, and there is an included angle α between the two side walls of the tooth-shaped groove 3, and the included angle α is 120°.

[0039] It should be noted here that: without affecting the stability of the central fixing member 2 itself, the two side walls of the tooth-shaped groove 3 are designed in a V shape, and the included angle α is 120°. This can enable the casting material to be cast into the tooth-shaped groove 3, thereby making the combination with the central fixing member 2 more firm, increasing the holding force of the central fixing member 2, and enabling the main body 1 of the microcrystalline plate to have better connection stability.

[0040] The projected distances of the two side walls of the tooth-shaped groove 3 in the vertical direction are equal.

[0041] The tooth-shaped grooves 3 on two adjacent side walls of the central fixing member 2 are arranged staggeredly.

[0042] It should be noted here that: adopting the staggered arrangement design ensures that the connection between the periphery of the central fixing member 2 and the casting material is more uniform.

[0043] The main body 1 of the microcrystalline plate includes a lower bottom plate 6 and an upper bottom plate 7. The lower bottom plate 6 and the upper bottom plate 7 are arranged in a staggered manner. The four side surfaces of the lower bottom plate 6 and the four side surfaces of the upper bottom plate 7 are not in the same plane. The front and rear side surfaces of the upper bottom plate 7 protrude forward relative to the front and rear side surfaces of the lower bottom plate 6, and the left and right side surfaces of the upper bottom plate 7 protrude rightward relative to the left and right side surfaces of the lower bottom plate 6.

[0044] It should be noted here that: between two adjacent main bodies 1 of the microcrystalline plate, they are mutually engaged and spliced through the groove portion 4 and the flange portion 5, so that when the four sides of the main body 1 of the microcrystalline plate are respectively spliced with the adjacent main body 1 of the microcrystalline plate, a bending gap 10 is formed between the two main bodies 1 of the microcrystalline plate. Compared with a linear gap, the bending gap 10 has the effect of changing the direction of high-temperature heat flow. The high-temperature heat flow cannot directly pass through the gap to contact the casting material, further improving the service life of the industrial kiln.

[0045] The central fixing member 2 is arranged in the middle of the upper end surface of the upper bottom plate 7, and the lower bottom plate 6, the upper bottom plate 7 and the central fixing member 2 are integrally formed.

[0046] It should be noted here that: the integrally formed design reduces the assembly process and improves the structural strength and integrity of the microcrystalline plate.

[0047] The main body 1 of the microcrystalline plate adopts an anti-crusting and super wear-resistant nano-microcrystalline plate.

[0048] It should be noted here that: it has a good anti-crusting effect, and it also has excellent hardness, thermal stability, high strength, wear resistance and corrosion resistance.

[0049] A connection hole 8 for the steel bar 9 to pass through is respectively opened at the upper end and the lower end of the central fixing member 2.

[0050] It should be noted here that the steel bar 9 passes through the connection holes 8 at the upper and lower ends of the central fixing member 2 and can be welded to the metal shell through heat-resistant steel anchor fittings. The connection and positioning are carried out through the steel bar 9, which improves the integrity of the main body 1 of the microcrystalline plate and enhances the bonding strength and stability between the main body 1 of the microcrystalline plate and the casting material.

[0052] The beneficial effects of the present utility model are:

[0053] (1) The adjacent two main bodies 1 of the microcrystalline plates are mutually engaged and spliced through the groove portion 4 and the flange portion 5, which not only improves the convenience of laying the main body 1 of the microcrystalline plate, but also makes the integrity of the microcrystalline plate assembly better;
