Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a device for improving large roller gap deviation of a roller press. Background Art

[0002] Roller press is needed in cement production. It is designed based on the principle of bed grinding. Its main features are: high pressure, full speed, full material, and bed crushing. The roller press includes two extrusion rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. The material is fed from above the two rollers and is continuously brought into the roller space by the extrusion rollers. After being subjected to a high pressure of 100-150MPa, it becomes a dense cake and is discharged from the bottom of the machine.

[0003] In the prior art, after a roller press has been used for a long time, a large roller gap deviation is likely to occur, which affects the quality and effect of the roller pressing and requires frequent shutdown for correction. Therefore, based on the above technical problems, improvements are needed. Utility Model Content

[0004] Aiming at the technical problems existing in the prior art, the utility model provides a device for improving the large roll gap deviation of a roller press.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for improving the large roll gap deviation of a roller press, the roller press comprises a movable roller and a fixed roller, the movable roller is rotatably connected to a movable frame, the fixed roller is connected to a rotating shaft, a bevel gear 1 is connected to the rotating shaft, bevel gear 1 is symmetrically meshed with bevel gear 2 on both sides of the bevel gear 1, the bevel gear 2 is connected to a connecting ring, the connecting ring is rotatably connected to a fixed plate, and the end of the connecting ring is provided with meshing teeth 1 arranged in a ring shape,

[0006] A deflection correction push plate is provided on one side of the movable frame away from the fixed roller, and the deflection correction push plate is connected to a translation component.

[0007] The translation assembly includes a threaded rod, a guide rod, a driving rod, and a sleeve. The deflection correction push plate is connected to a connecting plate that threadably cooperates with the threaded rod and a guide plate that slides with the guide rod. The threaded rod is hollow, and a connecting key extending along its axial direction is provided on the inner wall of the threaded rod. A key slot matching the connecting key is provided on the driving rod. One end of the driving rod is rotatably connected to the movable plate, and the other end is inserted into the threaded rod. The movable plate is connected to a movable telescopic device. The driving rod passes through a fixed plate and a connecting ring. The sleeve is fixed on the driving rod. The sleeve is arranged between two connecting rings. Both end surfaces of the sleeve are respectively provided with meshing teeth 2 that are arranged in a ring and mesh with meshing tooth 1.

[0008] When the roller gap deviation becomes larger, the movable frame approaches the deflection correction push plate, and the translation assembly is used to realize the forward and reverse movement of the deflection correction push plate. When the roller gap deviation reaches the preset maximum value, the translation assembly drives the deflection correction push plate to move toward the direction of the fixed roller. When the deflection correction push plate moves, it pushes the movable frame to move synchronously, thereby reducing the roller gap and realizing the deflection correction. When the roller gap is reduced to the preset minimum value, the translation assembly drives the deflection correction push plate to move in the opposite direction, returning it to its initial position to prevent it from affecting the normal rolling.

[0009] Preferably, the correcting push plate includes a correcting seat and a movable plate, the correcting seat is provided with a receiving groove for inserting one end of the movable plate, an adjusting telescopic device is provided in the receiving groove, and the telescopic end of the adjusting telescopic device is connected to the movable plate.

[0010] By adjusting the telescopic device, the length of the movable plate extending out of the accommodating slot can be changed, so that the preset maximum value of the roller gap deviation can be adjusted according to production needs.

[0011] Preferably, a sealing ring is provided between the side wall of the accommodating groove and the movable plate.

[0012] The sealing ring can prevent dust and impurities generated during rolling from entering the containing groove, thereby playing a protective role for the adjusting and telescopic equipment.

[0013] Preferably, a limit block for limiting the position of the movable roller is provided between the movable roller and the fixed roller, the limit block is slidably connected to the slide rail, and the limit block is connected to the second adjusting and telescopic device.

[0014] The limit block can limit the movable frame when the correction push plate corrects the roll gap of the movable roller, so that the roll gap is not less than the preset minimum value, avoiding the roll gap being too small and affecting the rolling effect.

[0015] The position of the limit block can be adjusted by adjusting the telescopic device 2, thereby achieving the adjustment of the preset minimum value of the roller gap.

[0016] The utility model also includes other components that can make the device for improving the large roll gap deviation of the roller press machine work normally, which are all conventional technical means in the art. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the art.

[0017] The utility model can correct the roll gap when the roll gap deviation is large, ensure that the roll gap is within the normal process range, thereby ensuring the normal rolling and rolling effect, and the roll gap range is adjustable, which can meet different use requirements and improve the use flexibility.

[0028] Example 1

[0029] See also Figure 1-4 A device for improving the large roll gap deviation of a roller press, the roller press comprises a movable roller 1 and a fixed roller, the movable roller 1 is rotatably connected to a movable frame 3, the fixed roller 2 is connected to a rotating shaft, a bevel gear 1 4 is connected to the rotating shaft, bevel gear 1 5 is symmetrically meshed on both sides of the bevel gear 1 4, the bevel gear 2 5 is connected to a connecting ring 6, the connecting ring is rotatably connected to a fixed plate 7, and the end of the connecting ring 6 is provided with a meshing tooth 1 8 arranged in a ring shape,

[0030] The movable frame 3 is provided with a deflection correction push plate on one side away from the fixed roller 2, and the deflection correction push plate is connected with a translation component.

[0031] The translation assembly includes a threaded rod 10, a guide rod 11, a driving rod 12, and a sleeve 13. The deflection correction push plate is connected to a connecting plate threadedly matched with the threaded rod 10 and a guide plate slidingly matched with the guide rod 11. The threaded rod 10 is hollow, and a connecting key 14 extending along its axial direction is provided on the inner wall of the threaded rod 10. A keyway matching the connecting key is provided on the driving rod 12. One end of the driving rod 12 is rotatably connected to the movable plate 15, and the other end is inserted into the threaded rod 10. The movable plate is connected to a movable telescopic device 16. The driving rod 12 passes through the fixed plate 7 and the connecting ring 6. The sleeve 13 is fixed on the driving rod 12. The sleeve 13 is arranged between the two connecting rings 6. The two end surfaces of the sleeve 13 are respectively provided with meshing teeth 2 arranged in a ring and meshing with the meshing tooth 1.

[0032] In this embodiment, the threaded rod 10 is rotatably connected to the roller press, the guide rod 11 and the fixed plate are fixedly connected to the roller press, the fixed end of the movable telescopic device is connected to the roller press, and the telescopic end is connected to the movable plate.

[0033] When the roll gap deviation becomes larger, the movable frame 3 approaches the deflection correction push plate, and the translation assembly is used to realize the forward and reverse movement of the deflection correction push plate. When the roll gap deviation reaches a preset maximum value, the translation assembly drives the deflection correction push plate to move toward the direction of the fixed roller 2. When the deflection correction push plate moves, it pushes the movable frame 3 to move synchronously, thereby reducing the roll gap and realizing deflection correction. When the roll gap is reduced to a preset minimum value, the translation assembly drives the deflection correction push plate to move in the opposite direction, returning it to its initial position to prevent it from affecting the normal progress of rolling.

[0034] The fixed roller 2 is connected to a driving device. When the roller press is working, the fixed roller 2 rotates and drives the two bevel gears 2 5 to rotate in the opposite direction through the bevel gear 1 4. The sleeve 13 is located between the two connecting rings 6. At this time, the sleeve 13, the driving rod 12, and the threaded rod 10 do not rotate.

[0035] When the deflection correction push plate needs to be translated, the mobile telescopic device is started to change the position of the moving plate so that the meshing tooth 2 on the sleeve 13 meshes with the meshing tooth 1 on one of the connecting rings 6. Then, the sleeve 13 and the driving rod 12 move synchronously with the bevel gear 2 5 on the connecting ring 6, and the driving rod 12 drives the threaded rod 10 to rotate through the connecting key, thereby realizing the movement of the deflection correction push plate; similarly, when the sleeve 13 meshes with another connecting ring 6, the deflection correction push plate moves in the opposite direction.

[0036] The mobile telescopic device is used to realize the position conversion of the mobile plate. Its extension and retraction can be controlled manually or automatically in conjunction with the travel switch, position sensor, etc. of the prior art.

[0037] In this embodiment, the driving rod and the rotating shaft realize clutch transmission through bevel gear 1, bevel gear 2, sleeve and other components. Without adding a driving motor, the rotation of the fixed roller is used to realize the positive direction movement of the correction push plate. The structure is simple, the design is reasonable, and the equipment cost is reduced at the same time.

[0038] The correcting push plate includes a correcting seat 17 and a movable plate 9. The correcting seat 17 is provided with a receiving groove for inserting one end of the movable plate. An adjusting telescopic device 18 is provided in the receiving groove. The telescopic end of the adjusting telescopic device 18 is connected to the movable plate.

[0039] The connecting plate and the guide plate are connected to the deviation correcting seat 17 .

[0040] By adjusting the telescopic device 18, the length of the movable plate extending out of the accommodating slot can be changed, so that the preset maximum value of the roller gap deviation can be adjusted according to production needs.

[0041] A sealing ring 19 is provided between the side wall of the receiving groove and the movable plate.

[0042] The sealing ring can prevent dust and impurities generated during rolling from entering the containing groove, thereby playing a protective role for the adjusting and telescopic equipment.

[0043] Example 2

[0044] See also Figure 5-6 The difference between this embodiment and embodiment 1 is that a limit block 20 for limiting the movable roller is provided between the movable roller 1 and the fixed roller, the limit block is slidably connected to the slide rail 21, and the limit block is connected to an adjusting telescopic device 22.

[0045] In this embodiment, the slide rail is fixed on the roller press, and the slide rail is located above one side of the movable frame, which will not cause position interference to the movable roller. The fixed end of the second telescopic adjustment device is connected to the roller press, and the telescopic end is connected to the limit block.

[0046] The limit block can limit the movable frame when the correction push plate corrects the roll gap of the movable roller, so that the roll gap is not less than the preset minimum value, avoiding the roll gap being too small and affecting the rolling effect.

[0047] The position of the limit block can be adjusted by adjusting the telescopic device 2, thereby achieving the adjustment of the preset minimum value of the roller gap.

[0048] By adjusting the coordination of the telescopic device 1 and the telescopic device 2, the roller gap range can be adjusted to meet different production requirements.

[0049] The mobile telescopic device, the first adjustable telescopic device and the second adjustable telescopic device can all be made of electric telescopic rods, air cylinders, hydraulic cylinders, etc. of the prior art.

[0050] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
