Description

Technical Field

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

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

[0003] Currently, the inner linings of some furnaces and kilns are fixed on the castable by splicing some nano microcrystalline plates. Due to the large weight of the nano microcrystalline plates, they are very easy to fall off from the castable, and the splicing between nano microcrystalline plates is very difficult. Content 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 microcrystalline plate, which has the effect of facilitating the fixing of the nano microcrystalline plate on the castable and being easy to install between nano microcrystalline plates.

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

[0006] A nano microcrystalline plate, which includes: a microcrystalline unit plate and a plurality of connection and fixing parts. At least one installation groove is respectively opened at both ends of the microcrystalline unit plate, and the installation groove is recessed inward from the end face of the microcrystalline unit plate along its length direction to form a recess depth;

[0007] The lower end of each connection and fixing part is detachably fitted into the installation groove, and the width of the connection and fixing part is equal to twice the recess depth.

[0008] The specific technical effect is: by opening installation grooves at both ends of the microcrystalline unit plate for installing connection and fixing parts, the upper ends of the connection and fixing parts can be fixed in the castable, enhancing the bonding strength and stability between the microcrystalline unit plate and the castable, thereby playing a fixing role for the microcrystalline unit plate; the width of the connection and fixing part is equal to twice the recess depth of the installation groove, which ensures that one connection and fixing part can connect two microcrystalline unit plates to each other and can ensure the splicing error between adjacent two microcrystalline unit plates.

[0009] Further, the longitudinal section of the installation groove is in a trapezoidal structure, and the shape of the lower end of the connection and fixing part matches the trapezoidal structure.

[0010] Further, the cross-sectional dimension of the middle part of the connection and fixing part is smaller than the cross-sectional dimensions of both ends of the connection and fixing part.

[0011] Furthermore, both sides of the lower end of the connecting and fixing member gradually expand outward in the direction from top to bottom, and both sides of the upper end of the connecting and fixing member gradually expand outward in the direction from bottom to top.

[0012] The specific technical effect is that both sides of the lower end of the connecting and fixing member gradually expand outward in the direction from top to bottom, and the longitudinal section of the installation groove is trapezoidal. This design plays an anti-detachment role and avoids the microcrystalline unit board and the connecting and fixing member from detaching in their height direction.

[0013] Furthermore, the microcrystalline unit board includes a bottom plate and a number of convex platforms integrally formed. The number of the convex platforms are both arranged at both ends of the upper end of the bottom plate, and the upper end surface of the convex platform is recessed downward to form the installation groove.

[0014] The specific technical effect is that by designing the convex platform, only the depth of the installation groove is increased in the height direction, without increasing the thickness of the entire bottom plate, which ensures the connection stability between the microcrystalline unit board and the connecting and fixing member while further reducing the overall weight of the microcrystalline unit board.

[0015] Furthermore, the upper end of one side of the microcrystalline unit board is recessed inward along its width direction to form a groove, and the upper end of the other side of the microcrystalline unit board is protruded outward along its width direction to form a flange.

[0016] The specific technical effect is that adjacent two microcrystalline unit boards are mutually engaged and spliced through the groove and the flange along their width direction, which not only improves the convenience of paving the microcrystalline unit board, but also makes the integrity of the microcrystalline board assembly better.

[0017] Furthermore, a connection hole for a connecting steel bar to pass through is provided at the upper end of the connecting and fixing member.

[0018] The specific technical effect is that the steel bar passes through the connection hole at the upper end of the connecting and fixing member and can be welded to the shell of the casting material. The connection and positioning are carried out through the steel bar, which improves the integrity of the microcrystalline unit board and enhances the bonding strength and stability between the microcrystalline unit board and the casting material.

[0019] Furthermore, the microcrystalline unit board adopts an anti-crusting and super wear-resistant nano microcrystalline board.

[0020] 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.

[0021] A microcrystalline plate assembly, which is composed of a number of nano-microcrystalline plates as described in any one of the above, and adjacent two microcrystalline unit plates are connected by connecting and fixing parts along their length directions. Half of the lower end of the connecting and fixing part is inserted into the installation groove of one microcrystalline unit plate, and the other half of the lower end of the connecting and fixing part is inserted into the installation groove of the adjacent microcrystalline unit plate. Adjacent two microcrystalline unit plates are mutually engaged and connected along their width directions through grooves and flanges.

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

[0023] (1) By providing installation grooves at both ends of the microcrystalline unit plate for installing the connecting and fixing parts, the upper end of the connecting and fixing part can be fixed in the casting material, enhancing the bonding strength and stability between the microcrystalline unit plate and the casting material, thereby playing a role in fixing the microcrystalline unit plate.

[0024] (2) The width of the connecting and fixing part is equal to twice the depth of the depression of the installation groove, which ensures that one connecting and fixing part can connect two microcrystalline unit plates to each other and can ensure the splicing error between adjacent two microcrystalline unit plates.

Apparently, the described embodiments are some but not all of the embodiments of the present utility model. 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.

[0035] As Figures 1 to 2 shown, the nano-microcrystalline board includes a microcrystalline unit board 1 and four connecting and fixing members 2. Two installation grooves 3 are respectively formed at both ends of the microcrystalline unit board 1, and each installation groove 3 is recessed inward from the end face of the microcrystalline unit board 1 along its length direction to form a recess depth.

[0036] The lower end of each connecting and fixing member 2 is detachably fitted into an installation groove 3, and the width of the connecting and fixing member 2 is equal to twice the recess depth.

[0037] It should be noted here that: by forming the installation grooves 3 at both ends of the microcrystalline unit board 1 for installing the connecting and fixing members 2, the upper ends of the connecting and fixing members 2 can be fixed in the casting material, enhancing the bonding strength and stability between the microcrystalline unit board 1 and the casting material, thereby playing a fixing role for the microcrystalline unit board 1; the width of the connecting and fixing member 2 being equal to twice the recess depth of the installation groove 3 ensures that two microcrystalline unit boards 1 can be connected to each other using one connecting and fixing member 2 and can ensure the splicing error between two adjacent microcrystalline unit boards 1.

[0038] The longitudinal section of the installation groove 3 is in a trapezoidal structure, and the shape of the lower end of the connecting and fixing member 2 matches the trapezoidal structure.

[0039] The cross-sectional dimension of the middle part of the connecting and fixing member 2 is smaller than the cross-sectional dimensions of both ends of the connecting and fixing member 2.

[0040] The two sides of the lower end of the connecting and fixing member 2 gradually expand outward in the direction from top to bottom, and the two sides of the upper end of the connecting and fixing member 2 gradually expand outward in the direction from bottom to top.

[0041] It should be noted here that: the two sides of the lower end of the connecting and fixing member 2 gradually expand outward in the direction from top to bottom, and the longitudinal section of the installation groove 3 is in a trapezoidal structure. This design plays an anti-detachment role to prevent the microcrystalline unit board 1 and the connecting and fixing member 2 from detaching in their height direction.

[0042] The microcrystalline unit board 1 includes an integrally formed bottom plate 4 and four bosses 5. The four bosses 5 are all arranged at both ends of the upper end of the bottom plate 4, and the upper end surface of the boss 5 is recessed downward to form a mounting groove 3.

[0043] It should be noted here that by designing the boss 5 to only increase the depth of the mounting groove 3 in the height direction without increasing the thickness of the entire bottom plate 4, the connection stability between the microcrystalline unit board 1 and the connecting and fixing member 2 is ensured while further reducing the overall weight of the microcrystalline unit board 1.

[0044] On one side of the microcrystalline unit board 1, the upper end is recessed inward along its width direction to form a groove 6, and on the other side of the microcrystalline unit board 1, the upper end is protruded outward along its width direction to form a flange 7.

[0045] It should be noted here that adjacent two microcrystalline unit boards 1 are mutually engaged and spliced along their width directions through the groove 6 and the flange 7, which not only improves the convenience of paving the microcrystalline unit board 1 but also makes the integrity of the microcrystalline board assembly 9 better.

[0046] The upper end of the connecting and fixing member 2 is provided with a connecting hole 8 for a connecting steel bar to pass through.

[0047] It should be noted here that the steel bar passes through the connecting hole 8 at the upper end of the connecting and fixing member 2 and can be welded to the shell of the cast material. Through the connection and positioning by the steel bar, the integrity of the microcrystalline unit board 1 is improved, and the bonding strength and stability between the microcrystalline unit board 1 and the cast material are enhanced.

[0048] The microcrystalline unit board 1 adopts an anti-crusting and ultra-wear-resistant nano-microcrystalline board.

[0049] 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.

[0050] See Figures 3 to 5 As shown, a microcrystalline board assembly 9 includes a plurality of nano-microcrystalline boards laid and joined together as described in any one of the above. Adjacent two microcrystalline unit boards 1 are connected along their length directions by a connecting and fixing member 2. Half of the lower end of the connecting and fixing member 2 is inserted into the mounting groove 3 of one microcrystalline unit board 1, and the other half of the lower end of the connecting and fixing member 2 is inserted into the mounting groove 3 of the adjacent microcrystalline unit board 1. Adjacent two microcrystalline unit boards 1 are mutually engaged and connected along their width directions through the groove 6 and the flange 7.

[0051] The beneficial effects of the present utility model are:

[0052] (1). By opening mounting grooves 3 at both ends of the microcrystalline unit board 1 for installing the connecting and fixing member 2, the upper end of the connecting and fixing member 2 can be fixed in the cast material, enhancing the bonding strength and stability between the microcrystalline unit board 1 and the cast material, thereby playing a fixing role for the microcrystalline unit board 1;

[0053] (2) The width of the connecting fixture 2 is equal to twice the recess depth of the installation groove 3, which ensures that two microcrystalline unit plates 1 can be connected to each other using one connecting fixture 2, and the splicing error between two adjacent microcrystalline unit plates 1 can be ensured.
