Description

Technical Field

[0001] This utility model relates to the field of cement kiln technology, and in particular to a modular combination tertiary air valve plate for cement rotary kilns. Background Technology

[0002] The cement industry has developed various production methods and types of rotary kilns. Based on the raw material preparation method, it can be divided into wet process and dry process production. Rotary kilns, corresponding to these methods, are also classified into wet process rotary kilns and dry process rotary kilns. Due to differences in the heat exchange devices at the kiln tail, they can also be classified into different types. Dry process kilns, due to their high output, have surplus hot air called tertiary air, which enters the decomposer for combustion through tertiary air ducts. The tertiary air duct valves are crucial equipment in dry process kilns, playing a role in balancing the kiln's airflow.

[0003] Patent document CN104390025B discloses a high-temperature wear-resistant valve plate for tertiary air ducts, comprising a valve plate body and a heat-resistant steel reinforcement frame. Multiple palladium nails are welded onto the heat-resistant steel reinforcement frame, with the number of nails gradually increasing from the rear end to the front end of the valve plate body, and each nail having a different orientation. At least two protrusions are provided at the top of the valve plate body, with a reinforcing frame inside each protrusion. The reinforcing frame has at least one lifting hole for easy lifting of the valve plate body. The advantages of this invention are: the multiple palladium nails on the heat-resistant steel reinforcement frame within the valve plate body, arranged with a gradual increase from the rear end to the front end, ensure good overall integrity of the valve plate body. It exhibits good wear resistance, mechanical impact resistance, excellent anti-stripping and anti-cracking properties, long service life, convenient construction, safety, and reliability, significantly shortening the construction period. The protrusions have lower production costs and better stability compared to lifting lugs. The reinforcing frame structure, composed of horizontal ribs, vertical ribs, and collars, is simple and easy to produce.

[0048] Example 1

[0049] Reference Figures 1-19 The modular combination tertiary air valve plate for cement rotary kilns includes a support mechanism, a brick body mechanism, and a positioning mechanism. The support mechanism is used to connect the brick body mechanism and the positioning mechanism, and the brick body mechanism is installed on the outside of the positioning mechanism for splicing.

[0050] The support mechanism includes a crossbeam 1, which is used to fix the positioning mechanism and limit the movement of the brickwork mechanism.

[0051] The positioning mechanism includes a first pin 2, a second pin 3, and a locking plate assembly. The first pin 2 is evenly fixed inside the middle of the bottom end of the crossbeam 1. The second pin 3 is fixed at the bottom of the crossbeam 1 and at both ends of the first pin 2. The outer sides of the first pin 2 and the second pin 3 are slidably assembled with the brick mechanism. The bottom plane of the second pin 3 is higher than the bottom plane of the first pin 2, so that the second pin 3 is at both ends of the first pin 2 and the length of the second pin 3 is less than the length of the first pin 2. At the same time, the tops of the first pin 2 and the second pin 3 are on the same plane through the crossbeam 1. The locking plate assembly is installed on the outer side of the first pin 2 and the second pin 3 for positioning the brick mechanism located outside the first pin 2 and the second pin 3.

[0052] The locking plate assembly includes a first locking plate 4, a second locking plate 5, a third locking plate 6, a fourth locking plate 7, and a support shaft 9. The first locking plates 4 are evenly distributed and fixed on the outer sides of the first pin 2 and the second pin 3, so that the connecting bricks of different layers are fixed by fixing the first locking plates 4 on the first pin 2 and the second pin 3. The second locking plates 5 are fixed on the outer sides of the multiple first pins 2 and at the bottom of the first locking plates 4, so that the bottom of the connecting brick located in the penultimate layer is supported by the second locking plates 5.

[0053] A third locking piece 6 is fixed between the bottom end of the second pin 3 and the adjacent first pin 2. A support shaft 9 is fixed between the bottom of the third locking piece 6 and the second locking piece 5. The position of the third locking piece 6 is fixed by the first pin 2 and the second pin 3, and the third locking piece 6 is supported again by the support shaft 9. A fourth locking piece 7 is fixed on the outside of the first pin 2 and the second pin 3 at a position that intersects with the first locking piece 4 and the second locking piece 5. The bottom of a single connecting brick is supported by the fourth locking piece 7, and the connecting brick at the bottom layer is fixed by the fourth locking piece 7 located at the bottom of the first pin 2 and the second pin 3, thereby preventing the brick body mechanism from detaching from the first pin 2 and the second pin 3.

[0054] The brickwork mechanism includes multiple connecting bricks for mounting on the outer sides of the first pin 2 and the second pin 3. Through the assembly of the brickwork mechanism, the support mechanism and the positioning mechanism form a damper plate. The multiple connecting bricks consist of a first connecting brick 10, a second connecting brick 11, a third connecting brick 12, a fourth connecting brick 13, a fifth connecting brick 14, a sixth connecting brick 15, a seventh connecting brick 16, an eighth connecting brick 17, and a ninth connecting brick 18. The first connecting brick 10, the fourth connecting brick 13, and the fifth connecting brick 14 are positioned on the outer side of the second pin 3 from near to away from the second connecting brick 11, and all three connecting bricks are connected to the second pin 3. The shaft 3 is slidably connected, allowing the first connecting brick 10, the fourth connecting brick 13, and the fifth connecting brick 14 to be slidably installed on the outside of the second pin 3. At the same time, the first connecting brick 10 and the fourth connecting brick 13, as well as the fourth connecting brick 13 and the fifth connecting brick 14, are slidably assembled. The sixth connecting brick 15 and the seventh connecting brick 16 are slidably connected on the outside of the first pin 2 near one end of the second pin 3 and at the bottom of the fifth connecting brick 14. The sixth connecting brick 15 and the seventh connecting brick 16 are slidably connected, thereby enabling the positioning of the first connecting brick 10, the fourth connecting brick 13, the fifth connecting brick 14, the sixth connecting brick 15, and the seventh connecting brick 16.

[0055] A second connecting brick 11 is slidably connected to the outside of the central first pin 2 and to the top of the seventh connecting brick 16. A third connecting brick 12 is slidably connected to the outside of the first pin 2 between the second connecting brick 11 and the first connecting brick 10. This allows the second connecting brick 11 and the third connecting brick 12 to be staggered on the outside of adjacent first pins 2 on the same plane. The third connecting brick 12 is slidably assembled with the second connecting brick 11, and the second connecting brick 11 is slidably assembled with the first connecting brick 10, the fourth connecting brick 13, the fifth connecting brick 14, or the sixth connecting brick 15. The second connecting brick 11 is also slidably connected with the first connecting brick 10, the fourth connecting brick 13, or the fifth connecting brick 15. The sliding assembly of connecting brick 14 or the sixth connecting brick 15 enables connection and positioning on different planes; the two seventh connecting bricks 16 are slidably connected at one end to the eighth connecting brick 17, and the two eighth connecting bricks 17 are slidably connected to the ninth connecting brick 18. The eighth connecting brick 17 and the first pin 2 are slidably assembled, and the ninth connecting brick 18 and the first pin 2 are also slidably assembled. Thus, the two seventh connecting bricks 16 can be assembled by the staggered assembly of the eighth connecting brick 17 and the ninth connecting brick 18. In other embodiments, the number of the eighth connecting brick 17 and the ninth connecting brick 18 can be increased as needed, and they can be arranged in an staggered manner according to the second connecting brick 11 and the third connecting brick 12.

[0056] In this embodiment, the number of first connecting bricks 10 can be adjusted as needed on the outside of the first pin 2.

Side plates 19 are fixed to both sides of the middle plate 8, thus enabling the application of the first connecting brick 10, the second connecting brick 11, the third connecting brick 12, the fourth connecting brick 13, the fifth connecting brick 14, the sixth connecting brick 15, the seventh connecting brick 16, the eighth connecting brick 17, and the ninth connecting brick 18 formed by the middle plate 8 and the side plate 19. In the first connecting brick 10, the top plane of the middle plate 8 is higher than the top plane of the side plate 19, and one end of the middle plate 8 is flush with one end of the side plate 19, so that the other end of the middle plate 8 is located on the side plate 19.

[0058] In the fourth connecting brick 13, the top plane of the middle plate 8 is higher than the top plane of the side plate 19, making the bottom plane of the middle plate 8 lower than the bottom plane of the side plate 19. One end of the middle plate 8 is flush with one end of the side plate 19, and the other end and bottom of the middle plate 8 are located inside the side plate 19. One end of the fourth connecting brick 13 is a downward-curving arc, allowing the fourth connecting brick 13 to slide and connect with the second connecting brick 11 on the same plane. In the fifth connecting brick 14, the top plane of the middle plate 8 is higher than the top plane of the side plate 19, making... The bottom plane of the middle plate 8 in the fifth connecting brick 14 is lower than the bottom plane of the side plate 19. One end of the middle plate 8 in the fifth connecting brick 14 is flush with one end of the side plate 19. The other end and bottom of the middle plate 8 in the fifth connecting brick 14 are located inside the side plate 19. One end of the fifth connecting brick 14 is a downward arc, which allows the fifth connecting brick 14 and the second connecting brick 11 to slide and splice on the same plane. At the same time, it allows the fourth connecting brick 13 and the fifth connecting brick 14 to be spliced ​​at the same height, and allows the arc of one end of the fifth connecting brick 14 to be spliced ​​with the arc of one end of the fourth connecting brick 13.

[0059] The top plane of the middle plate 8 in the sixth connecting brick 15 is higher than the top plane of the side plate 19, making the bottom plane of the middle plate 8 in the sixth connecting brick 15 lower than the bottom plane of the side plate 19. One end of the middle plate 8 in the sixth connecting brick 15 is flush with one end of the side plate 19. The other end and bottom of the middle plate 8 in the sixth connecting brick 15 are located inside the side plate 19, and one end of the sixth connecting brick 15 is a downward arc, so that the sixth connecting brick 15 and the second connecting brick 11 can slide and splice on the same plane. At the same time, the top of the sixth connecting brick 15 and the bottom of the fifth connecting brick 14 can be spliced ​​at the same height through sliding. At the same time, the arc of one end of the sixth connecting brick 15 can be spliced ​​with the arc of one end of the fifth connecting brick 14.

[0060] The top plane of the middle plate 8 in the seventh connecting brick 16 is higher than the top plane of the side plate 19, so that the bottom plane of the middle plate 8 in the seventh connecting brick 16 is lower than the bottom plane of the side plate 19. One end of the middle plate 8 in the seventh connecting brick 16 is flush with one end of the side plate 19, and the other end of the middle plate 8 in the seventh connecting brick 16 is located inside the side plate 19.

[0061] The top and both ends of the middle plate 8 in the eighth connecting brick 17 extend beyond the side plate 19, making it easy for the eighth connecting brick 17 and the seventh connecting brick 16 to be assembled on the same plane by sliding, and allowing the top of the eighth connecting brick 17 to be assembled with the second connecting brick 11 or the third connecting brick 12 at a certain height. The top plane of the middle plate 8 in the ninth connecting brick 18 is higher than the top plane of the side plate 19. Both ends of the middle plate 8 in the ninth connecting brick 18 are located inside the side plate 19. The bottom of the middle plate 8 in the ninth connecting brick 18 is on the same plane as the bottom of the side plate 19, thus making it easy for the top of the ninth connecting brick 18 to be assembled with the second connecting brick 11 or the third connecting brick 12 at a certain height, and allowing the ninth connecting brick 18 to be assembled with the eighth connecting brick 17 on the same plane.

The second connecting brick 11 and the third connecting brick 12 are interleaved between the two fourth connecting bricks 13, and the second connecting brick 11 is slidably assembled with the fourth connecting brick 13. The first and second layers are positioned at the bottom by the alternation of the fourth locking piece 7 and the first locking piece 4. A third layer is then set at the bottom of the second layer, consisting of the fifth connecting brick 14, the second connecting brick 11, and the third connecting brick 12. The third connecting brick 12 is staggered between the fifth connecting bricks 14 at both ends, and the second connecting brick 11 is slidably assembled with the fifth connecting brick 14. The third layer is supported at the bottom by the third locking piece 6 and the corresponding fourth locking piece 7. The fourth layer is set at the bottom of the third layer.
