Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated parts, and in particular relates to a wear-resistant and high-temperature-resistant special-shaped prefabricated part. Background Art

[0002] In modern industrial production, industrial kilns are widely used in cement, steel, nonferrous metallurgy, petrochemical and other industries. Due to the different functions of industrial kilns, the design concepts of the kilns are different and the external dimensions are also very different. Industrial kilns are generally used in high-temperature environments. Several prefabricated parts are spliced ​​together and then welded to the metal shell through heat-resistant steel anchors.

[0003] Although prefabricated parts are all made of refractory materials, existing prefabricated parts are usually regular squares. After assembly, there will inevitably be linear gaps between adjacent prefabricated parts. This gap makes the prefabricated parts easy to wear. In addition, a layer of insulation layer is generally required on the metal shell. The high-temperature heat flow generated by the industrial kiln during use will also enter the insulation layer through the gap, making the insulation layer not resistant to high temperatures, thereby affecting the reliability and service life of the entire industrial kiln. Utility Model Content

[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of the present invention is to provide a wear-resistant and high-temperature resistant special-shaped prefabricated part, which has the effects of wear resistance, high temperature resistance and good stacking effect.

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

[0006] A wear-resistant and high-temperature resistant special-shaped preform, comprising: a first portion, a second portion, and a connecting portion, wherein the first portion and the second portion are connected by the connecting portion, the upper surface of the connecting portion completely overlaps with the lower surface of the first portion and are integrally formed, and the lower surface of the connecting portion completely overlaps with the upper surface of the second portion and are integrally formed;

[0007] The first part and the second part are staggered, and the four side surfaces of the first part and the four side surfaces of the second part are not located in the same plane, so that when the four sides of the special-shaped preform are spliced ​​with the adjacent special-shaped preforms, a bending gap is formed between the two special-shaped preforms.

[0008] The specific technical effect is: by staggering the first part and the second part, the first part and the second part are connected by a connecting part, which is more wear-resistant, and the four side surfaces of the first part and the four side surfaces of the second part are not located in the same plane, so that when the four sides of the special-shaped prefabricated part are spliced ​​with the adjacent special-shaped prefabricated parts, a bending gap is formed between the two special-shaped prefabricated parts. Compared with the straight gap, the special-shaped prefabricated parts are surrounded by bending gaps, and the high-temperature heat flow cannot directly enter the insulation layer through the gap. The heat flow direction is changed by the bending gap, the stacking effect is good, and the insulation layer is more resistant to high temperatures.

[0009] Furthermore, the four side surfaces of the connecting portion are all inclined, and every two opposite side surfaces of the connecting portion are parallel.

[0010] The specific technical effect is: by adopting this structural design, the four side surfaces of the connecting part are all inclined to form a bent part of the bent gap, thereby changing the direction of heat flow.

[0011] Furthermore, the cross-sectional shape of the connecting portion along the width direction is a parallelogram, and the cross-sectional shape of the connecting portion along the length direction is a parallelogram.

[0012] Furthermore, the front and rear side surfaces of the second part protrude forward relative to the front and rear side surfaces of the first part, and the left and right side surfaces of the second part protrude rightward relative to the left and right side surfaces of the first part.

[0013] The specific technical effect is: this design allows for a misalignment between the second part and the first part, making it easier for bending gaps to be formed around the special-shaped prefabricated part when it is spliced ​​with adjacent special-shaped prefabricated parts, thereby providing protection around the prefabricated part. This allows the high-temperature heat flow around the prefabricated part to change direction through the bending gaps, thereby achieving all-round high-temperature protection for the insulation layer.

[0014] Furthermore, a hanging ring is provided on the upper surface of the first part.

[0015] The specific technical effect is that the hanging ring is provided to facilitate the transportation of the prefabricated parts and to facilitate the removal of the prefabricated parts from the casting mold through the hanging ring.

[0016] Furthermore, a round steel fixing piece is included, and a mounting groove for mounting the round steel fixing piece is provided on one side surface of the second part.

[0017] The specific technical effect is: by arranging round steel fixing parts, a number of special-shaped prefabricated parts are welded to the metal shell, thereby achieving a close combination between the special-shaped prefabricated parts and the kiln shell.

[0018] Furthermore, the round steel fixing member includes a first steel body, a second steel body and a third steel body. The first steel body and the third steel body are respectively connected to two ends of the second steel body, and the first steel body and the third steel body are arranged back to back.

[0019] Furthermore, the mounting groove includes a first groove and a second groove, the first groove is recessed inward from one side surface of the second part, the second groove extends from the outer edge of the lower surface of the second part to the first groove, the first steel body is inserted into the first groove, and the second steel body is buried in the second groove.

[0020] The specific technical effect is: the round steel fixing part and the installation groove adopt this design, the first steel body is inserted into the first groove, the second steel body is buried in the second groove, and the third steel body is used to be welded to the metal shell. The cooperation between the first steel body and the first groove achieves a limiting effect, thereby realizing a close combination between the special-shaped prefabricated part and the kiln shell.

[0021] Furthermore, the cross section of the second groove is semicircular, and the radius of the second groove is greater than the diameter of the second steel body.

[0022] The specific technical effect is: the radius of the second groove is greater than the diameter of the second steel body, ensuring that the second steel body can be completely buried in the second groove, that is, the outermost surface of the second steel body is lower than the upper surface of the second groove, avoiding affecting the splicing between special-shaped prefabricated parts.

[0023] The beneficial effects of the utility model are:

[0024] By staggering the first part and the second part, the first part and the second part are connected by a connecting part, which is more wear-resistant. The four side surfaces of the first part and the four side surfaces of the second part are not located in the same plane, so that when the four sides of the special-shaped prefabricated part are spliced ​​with the adjacent special-shaped prefabricated parts, a bending gap is formed between the two special-shaped prefabricated parts. Compared with the straight gap, bending gaps are formed on all sides of the special-shaped prefabricated part. High-temperature heat flow cannot directly enter the insulation layer through the gap. The heat flow direction is changed by the bending gap, and the stacking effect is good, making the insulation layer more resistant to high temperatures.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figures 1 to 8As shown, the wear-resistant and high-temperature resistant special-shaped preform has a first part 1 and a second part 2 connected by a connecting portion 3. The upper surface of the connecting portion 3 completely overlaps with the lower surface of the first part 1 and is formed as one piece. The lower surface of the connecting portion 3 completely overlaps with the upper surface of the second part 2 and is formed as one piece.

[0039] The first part 1 and the second part 2 are staggered, and the four side surfaces of the first part 1 and the four side surfaces of the second part 2 are not located in the same plane, so that a bending gap 4 is formed between the two special-shaped preforms when the four sides of the special-shaped preform are spliced ​​with adjacent special-shaped preforms.

[0040] It should be noted here that: by staggering the first part 1 and the second part 2, the first part 1 and the second part 2 are connected by a connecting part 3, which is more wear-resistant, and the four side surfaces of the first part 1 and the four side surfaces of the second part 2 are not located in the same plane, so that when the four sides of the special-shaped preform are spliced ​​with the adjacent special-shaped preforms, a bending gap 4 is formed between the two special-shaped preforms. Compared with the straight gap, the special-shaped preforms have bending gaps 4 formed on all sides, and the high-temperature heat flow cannot directly enter the insulation layer through the gap. The heat flow direction is changed by the bending gap 4, and the stacking effect is good, so that the insulation layer is more resistant to high temperatures.

[0041] The width of the bending gap 4 formed between two adjacent special-shaped preforms when they are spliced ​​is 2 mm.

[0042] The four side surfaces of the connecting portion 3 are all inclined, and every two opposite side surfaces of the connecting portion 3 are parallel.

[0043] It should be noted here that: by adopting this structural design, the four side surfaces of the connecting portion 3 are all inclined, forming a bent portion of the bent gap 4, thereby changing the direction of heat flow.

[0044] The cross-sectional shape of the connecting portion 3 along the width direction is a parallelogram, and the cross-sectional shape of the connecting portion 3 along the length direction is a parallelogram.

[0045] The front and rear side surfaces of the second part 2 protrude forward relative to the front and rear side surfaces of the first part 1 , and the left and right side surfaces of the second part 2 protrude rightward relative to the left and right side surfaces of the first part 1 .

[0046] It should be noted here that this design creates an offset between the second part 2 and the first part 1, making it easier for the four sides of the special-shaped preform to be spliced ​​with adjacent special-shaped preforms, thereby forming a protection around the preform, so that the high-temperature heat flow around it can change its direction through the bending gap 4, thereby achieving all-round high-temperature protection for the insulation layer.

[0047] A hanging ring 5 is provided on the upper surface of the first part 1 .

[0048] It should be noted here that the hanging ring 5 is provided to facilitate the transportation of the prefabricated parts and to facilitate the removal of the prefabricated parts from the casting mold through the hanging ring 5 .

[0049] It also includes a round steel fixing piece 6 , and a mounting groove 7 for mounting the round steel fixing piece 6 is provided on one side surface of the second part 2 .

[0050] It should be noted here that: by arranging the round steel fixing members 6 to weld a plurality of special-shaped prefabricated parts to the metal shell, a tight connection between the special-shaped prefabricated parts and the kiln shell is achieved.

[0051] The round steel fixing member 6 includes a first steel body 8, a second steel body 9 and a third steel body 10. The first steel body 8 and the third steel body 10 are respectively connected to the two ends of the second steel body 9, and the first steel body 8 and the third steel body 10 are arranged back to back.

[0052] The mounting groove 7 includes a first groove 11 and a second groove 12. The first groove 11 is recessed inward from one side surface of the second part 2, and the second groove 12 extends from the outer edge of the lower surface of the second part 2 to the first groove 11. The first steel body 8 is inserted into the first groove 11, and the second steel body 9 is buried in the second groove 12.

[0053] It should be noted here that the round steel fixing piece 6 and the mounting groove 7 are designed in this way, the first steel body 8 is inserted into the first groove 11, the second steel body 9 is buried in the second groove 12, and the third steel body 10 is used to be welded to the metal shell. The cooperation between the first steel body 8 and the first groove 11 achieves a limiting effect, thereby realizing a tight combination between the special-shaped prefabricated part and the kiln shell.

[0054] The cross section of the second groove 12 is semicircular, and the radius of the second groove 12 is greater than the diameter of the second steel body 9 .

[0055] It should be noted here that the radius of the second groove 12 is greater than the diameter of the second steel body 9, ensuring that the second steel body 9 can be completely buried in the second groove 12, that is, the uppermost surface of the second steel body 9 is lower than the upper surface of the second groove 12, avoiding affecting the splicing between the special-shaped prefabricated parts.

[0056] The beneficial effects of the utility model are:

[0057] By staggering the first part 1 and the second part 2, the first part 1 and the second part 2 are connected by a connecting part 3, which is more wear-resistant. The four side surfaces of the first part 1 and the four side surfaces of the second part 2 are not located in the same plane, so that when the four sides of the special-shaped preform are spliced ​​with the adjacent special-shaped preforms, a bending gap 4 is formed between the two special-shaped preforms. Compared with the straight gap, bending gaps 4 are formed on all sides of the special-shaped preforms. High-temperature heat flow cannot directly enter the insulation layer through the gap. The heat flow direction is changed by the bending gap 4, and the stacking effect is good, making the insulation layer more resistant to high temperatures.
