Description

Technical Field

[0001] This invention relates to the field of rotary kiln technology, and in particular to an energy-saving rotary kiln for a new type of dry-process cement production line. Background Technology

[0002] A rotary kiln is a large-scale calcination equipment widely used in industries such as cement, metallurgy, and chemicals. Its main structure is a slightly inclined, rotatable cylindrical shape. The material enters from the bottom of the kiln, moves forward on the inclined surface of the kiln, and is affected by the rotation of the kiln and the high temperature, eventually reaching the outlet end of the kiln for discharge. Rotary kilns have advantages such as high calcination temperature, uniform material, and excellent product quality, and are widely used in various industrial production. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns, and lime kilns according to the different materials they process. Cement kilns are mainly used for calcining cement clinker and are divided into two main categories: dry process cement kilns and wet process cement kilns.

[0003] The rotary kiln is a key piece of equipment in cement clinker production. Its structure includes a cylinder, support system, transmission system, kiln head, and kiln tail. The cylinder is constructed by rolling and welding steel plates, with an axial inclination of 3-5% to allow material movement towards the kiln head. Its function is to calcine raw materials into clinker, providing the basic raw materials for cement production. Inside the rotary kiln, the raw materials undergo preheating, decomposition, calcination, and cooling processes, achieving the transformation from raw materials to clinker. Traditional cement rotary kilns typically have a single-layer structure, meaning only a layer of refractory bricks is laid inside the outer cylinder, while the cement production raw materials are heated and rotated within this cylinder. The conveying process can lead to some raw materials accumulating together for heating and conveying, resulting in low heating rates for some materials and affecting the calcination quality of cement raw materials. In addition, during the installation of the rotary kiln, the main stress points of its cylinder are on the bottom support rollers. In order to ensure that the two ends of the cylinder can be accurately connected with the kiln head and kiln tail, multiple bearing seats with support rollers need to be displaced. However, due to the large weight of the cylinder itself, it is very difficult to adjust the distance between multiple support rollers. At the same time, it is impossible to ensure that the adjustment distance of the support rollers on the same side is consistent, resulting in excessively long adjustment and calibration time for the support rollers. Summary of the Invention

[0004] The purpose of this invention is to provide a novel energy-saving rotary kiln for a dry-process cement production line, which can effectively solve the problems in the background art.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-7 As shown, the present invention provides an energy-saving rotary kiln for a novel dry-process cement production line, comprising a first support frame 1 and a second support frame 2. A drive motor 8 is fixedly installed on one side of the upper end of the first support frame 1. The drive motor 8 is electrically connected to an external controller via a cable. Four mounting beams 9 are also provided on the first support frame 1 on both sides of the drive motor 8. Bearing seats 10 are fixedly installed on the upper end of the mounting beams 9. Support rollers 11 are movably installed between the two bearing seats 10. An outer cylinder 3 is provided between the four support rollers 11. A kiln tail 4 is movably installed at one end of the outer cylinder 3, and a kiln head 5 is movably installed at the other end of the outer cylinder 3. Two tires 6 are fixedly installed on the outer side of the outer cylinder 3. A large gear 7 is also fixedly installed on the outer cylinder 3 between the two tires 6. The outer cylinder 3 is also movably installed on the four support rollers 11 via the two tires 6. On wheel 11, the large gear 7 meshes with the small gear at the output end of the drive motor 8. The top of the mounting beam 9 is provided with a sliding groove 12. The mounting beam 9 is provided with an adjustment mechanism 13. The adjustment mechanism 13 includes a first stud 14 and a connecting rod 15. The first stud 14 is movably installed in the mounting beam 9, and the connecting rod 15 is movably installed in the first stud 14. One end of the connecting rod 15 is also provided with a drive mechanism 16. The drive mechanism 16 includes a handwheel 17 and a sprocket 19. A connecting shaft 18 is fixedly installed in the center of the handwheel 17 through multiple first connecting rods 31. The connecting shaft 18 is fixedly installed in one end of the connecting rod 15. The sprocket 19 is fixedly installed in one side of the handwheel 17. The outer cylinder 3 is provided with an inner cylinder 21. The inner cylinder 21 is fixedly installed in one side of the outer cylinder 3 through multiple second studs 40 and an adjustment rod 41.

[0029] A slider 45 is fixedly installed at the center of the lower end of the bearing housing 10. An insertion hole 26 is provided in the slider 45. The bearing housing 10 is placed on the mounting beam 9, and the lower end of the slider 45 extends through the slide groove 12 to the center of the mounting beam 9. The bearing housing 10 is installed on the mounting beam 9, and with the help of the slider 45, it can be moved in conjunction with the first stud 14.

[0030] Two support seats 22 are fixedly installed at the bottom of the mounting beam 9. A first limiting seat 23 is fixedly installed at the upper end of the support seat 22. A second limiting seat 43 is also fixedly installed at the upper end of the first limiting seat 23 by screws. A first rotating groove 24 is opened on the opposite side of the first limiting seat 23 and the second limiting seat 43 respectively. Two sets of first limiting seats 23 and second limiting seats 43 are set in the cavity inside the mounting beam 9, which allows the first stud 14 to be rotatably installed in the mounting beam 9.

[0031] The first stud 14 has an insertion hole 26, the longitudinal section of which is hexagonal. Both ends of the first stud 14 are fixedly installed with fixing rings 25. The fixing rings 25 are rotatably installed between the corresponding first limit seat 23 and second limit seat 43. The first stud 14 is rotatably installed in the mounting beam 9 through the fixing rings 25 at both ends. The slider 45 is threaded to the outside of the first stud 14 through the screw hole 46. The fixing rings 25 fixedly installed at both ends of the first stud 14 are rotatably installed between the corresponding first limit seat 23 and second limit seat 43, so that the first stud 14 can be rotatably installed between the two sets of first limit seats 23 and second limit seats 43. The insertion hole 26 in the first stud 14 allows the connecting rod 15 to be inserted into the first stud 14.

[0032] One end of the connecting rod 15 has a slot 27 and extends through the inner cavity of the mounting beam 9 to one side of the mounting beam 9. The connecting rod 15 is inserted into the insertion hole 26. The connecting rod 15 located on one side of one set of first limiting seats 23 and second limiting seats 43 is fixedly installed with a first limiting block 28. The end of the connecting rod 15 away from the slot 27 is fixedly installed with a connecting seat 29. One end of the connecting seat 29 is also fixedly installed with multiple connecting teeth 30. The distance between two connecting teeth 30 is equal to the width of the connecting teeth 30. The connecting seat 29 and connecting teeth 30 fixedly installed at one end of the connecting rod 15 enable the two connecting rods 15 to rotate synchronously when they move relative to each other, in coordination with the interpenetration of multiple connecting teeth 30.

[0033] A second limiting block 34 is fixedly installed on one end of the connecting shaft 18 relative to the connecting rod 15. Two second limiting blocks 34 on the same side are movably connected by a synchronizing rod 20. A plug 32 is fixedly installed at the center of one end of the second limiting block 34. Fastening screws are inserted into the connecting shaft 18 and the plug 32. The plug 32 is inserted into the slot 27 at one end of the corresponding connecting rod 15 and fixed by the fastening screws. A second rotating groove 35 is opened at both ends of the synchronizing rod 20. The two ends of the synchronizing rod 20 are rotatably installed on the corresponding second limiting blocks 34 through the second rotating groove 35. A plurality of second connecting rods 33 are fixedly installed on one end of the sprocket 19 relative to the handwheel 17. The other end is fixedly connected to the corresponding first connecting rod 31. The two sprockets 19 on the same side are connected by a chain. Multiple first buffer plates 36 are fixedly installed on the inner side of the outer cylinder 3. Multiple fixed seats 38 are also fixedly installed on the inner side of the outer cylinder 3. Limiting grooves 39 are opened in the fixed seats 38. The handwheel 17 can drive the connecting rod 15 to rotate by cooperating with the connecting shaft 18 and the insert block 32. This causes the connecting rod 15 to drive the first stud 14 to rotate. Thus, the first stud 14 can rotate in the screw hole 46 of the slider 45. At the same time, the handwheel 17 and the connecting shaft 18 can push the connecting rod 15 to move, which can then cooperate with the synchronizing rod 20 and the sprocket 19 to make the four connecting rods 15 rotate synchronously.

[0034] Multiple flow guide boxes 37 are fixedly installed at one end of the inner cylinder 21. One end of the flow guide box 37 is obliquely attached to the inner side of the outer cylinder 3. Multiple second buffer plates 44 are also fixedly installed on the outer side of the inner cylinder 21. The end of the second buffer plate 44 away from the inner cylinder 21 is attached to the inner side of the outer cylinder 3. One end of the second stud 40 is fixedly installed on the outer side of the inner cylinder 21. The adjusting rod 41 is threadedly connected to the second stud 40. One end of the adjusting rod 41 is also inserted into the corresponding limiting groove 39. A knob 42 is fixedly installed on the outer side of the adjusting rod 41. The inner cylinder 21 and the flow guide box 37, which are made of refractory bricks, can divert the cement raw materials in the outer cylinder 3 to improve heating efficiency and calcination efficiency. The first buffer plate 36, the second buffer plate 44, the fixed seat 38, the second stud 40, the adjusting rod 41, and the knob 42, which are made of alumina material, can install the inner cylinder 21 in the outer cylinder 3.

[0035] It should be noted that this invention relates to an energy-saving rotary kiln for a novel dry-process cement production line, as detailed in the appendix to this application. Figure 1 The explanation is as follows: When synchronously adjusting the two support rollers 11 in the X-axis direction on the first support frame 1, simply rotating the handwheel 17 is sufficient. The handwheel 17 then drives the connecting shaft 18 to rotate via the first connecting rod 31. The connecting shaft 18 is then fixedly connected to the connecting rod 15 via the insert block 32, thus driving the connecting rod 15 to rotate. Simultaneously, sprockets 19 are fixedly mounted on one side of the multiple first connecting rods 31 within the handwheel 17 via second connecting rods 33, allowing the handwheel 17 to synchronously drive the sprockets 19 to rotate. The two sprockets 19 in the X-axis direction are connected by a chain, thus driving one of the handwheels... Wheel 17 can synchronously drive two handwheels 17 to rotate, which in turn causes the connecting shaft 18 inside the two handwheels 17 to synchronously drive the two connecting rods 15 to rotate through the corresponding insert block 32. Thus, the connecting rod 15 drives the first stud 14 to rotate, which allows the first stud 14 to rotate between the two sets of first limit seats 23 and second limit seats 43 through the fixing rings 25 at both ends. At the same time, the first stud 14 also rotates in the insertion hole 26 of the corresponding lower end slider 45 of the bearing seat 10, which can synchronously drive the four bearing seats 10 to move, thereby enabling the two support rollers 11 in the X-axis direction on the first support frame 1 to be synchronously adjusted.

[0036] Additionally, if it is necessary to adjust the four bearing seats 10 on the first support frame 1, i.e., the two bearing seats 10 in the Y-axis direction as a group, a certain pressure can be applied to the connecting rod 15 when the handwheel 17 is turned. This will cause the synchronizing rod 20 to compress the compression spring fitted on the outside of the connecting rod 15. At the same time, when the connecting shaft 18 pushes the connecting rod 15 to move through the insert block 32, the second limiting block 34 simultaneously pushes the synchronizing rod 20 to move, thereby causing the synchronizing rod 20 to move synchronously with the other connecting shaft 18 in the X-axis direction on the first support frame 1. Thus, the two bearing seats 10 in the X-axis direction on the first support frame 1... One stud 14 moves synchronously to one side within the corresponding first stud 14 insertion hole 26, causing multiple connecting teeth 30 at one end of the two connecting rods 15 to be inserted and installed on one side of another connecting seat 29, and causing multiple connecting teeth 30 on one side of the two connecting seats 29 to be interlocked and connected to each other, thereby synchronously driving the four connecting rods 15 to rotate within the four first studs 14, thereby synchronously controlling the synchronous relative or opposite movement of the four bearing seats 10 in pairs, and thus adjusting the installation height of the outer cylinder 3. After the position of the support roller 11 is adjusted, the bearing seat 10 can be fixed to the mounting beam 9 with bolts.

[0037] When cement production raw materials enter the outer cylinder 3, part of the cement raw materials enter the inner cylinder 21 through the guide box 37, and the other part continues to enter the other side of the outer cylinder 3 through the gap between the two guide boxes 37. This results in excessive cement production raw materials accumulating in the outer cylinder 3, leading to a decrease in heating and calcination efficiency.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
