Description

Technical Field

[0001] This invention relates to the field of roller press technology, specifically to a cement roller press and a cement roller pressing method. Background Technology

[0002] Roller presses, also known as extrusion mills or roller mills, are used in the cement production industry. Cement raw materials are usually in the form of powder, and the production of these powdery materials is usually done by crushing larger particles using cement roller presses.

[0003] When using a traditional cement roller press, if most of the material falls into the middle of the roller, it will cause the middle of the roller to be squeezed by the material, resulting in deformation of the middle of the roller. On the other hand, the material concentrated in the same area will reduce the utilization rate of other areas, thus reducing the efficiency of the equipment. Summary of the Invention

[0009] As a preferred technical solution of the present invention: the roller assembly includes a roller body, a plurality of connecting tubes are annularly embedded in the inner cavity of the roller body along the axial direction, and a fixing rod is fixedly assembled at both ends of the connecting tubes. A sliding groove is opened on the outer wall of the middle part of the roller body, and an abutment rod is sleeved on the side of the fixing rod away from the axis of the roller body. A tension spring is sleeved on the outer wall of the fixing rod. The two ends of the tension spring are fixedly assembled to the inner wall of the end of the chute and the end of the abutment rod, respectively.

A second abutting shaft is fixedly assembled on both outer walls of the first abutting shaft. A cleaning brush is fixedly assembled on the bottom outer wall of the movable frame near the roller assembly. The first abutting shaft is located between two sets of abutting rods on the same axis, and the outer wall of the first abutting shaft overlaps with the outer wall of the roller body, and the outer wall of the second abutting shaft overlaps with the end of the abutting rod; The cubit-shaped frame and the outer wall of the protective cabin are fixedly assembled.

[0015] 2. The cement roller press and cement roller pressing method use a second abutment shaft to squeeze the abutment rod, causing the abutment rods at adjacent positions of the two sets of roller assemblies to extend and retract, thereby further squeezing the material located between the two sets of roller assemblies; after the abutment rod is squeezed, a tension spring pulls the abutment rod, causing it to contract. By utilizing the contraction and extension process of the abutment rod, the material adhering to the outer wall of the abutment rod is removed by scraping the abutment rod against the inner wall of the chute.

[0016] 3. The cement roller press and cement roller pressing method, by overlapping the outer wall of the first abutting shaft and the outer wall of the roller body, allows the force in the middle of the roller assembly to be transmitted to the first abutting shaft, thereby increasing the service life of the roller assembly.

[0022] In the above structure, the drive motor 201 and the support component 3 are connected by the universal drive shaft 202, so that the universal drive shaft 202 can adapt when the universal drive shaft 202 and the support component 3 are not on the same axis. The force output by the drive motor 201 through the universal drive shaft 202 is increased by the gearbox 203.

[0023] In a preferred embodiment: the support assembly 3 includes a base plate 301, a support clip 302 is fixedly mounted on the top of the base plate 301, and a mounting plate 303 is symmetrically arranged on the top of the support clip 302 and fixedly mounted to the outer wall of the gearbox 203.

[0024] In the above structure, the support component 3 supports the drive component 2.

[0025] In a preferred embodiment: the roller pressing assembly 6 includes two sets of symmetrically arranged roller assemblies 603. The two ends of the roller assembly 603 are rotatably connected to bearings 602. The outer wall of the bearings 602 is fixedly fitted with mounting plates 601. The outer walls of the two sets of roller assemblies 603 are sleeved with protective chambers 604. The outer walls of the two ends of the protective chambers 604 are provided with protective chambers 604. The outer walls on both sides of the protective chambers 604 are fixedly fitted with abutment components 606. The two ends of the roller assembly 603 are rotatably connected to the inner wall of the circular groove 605.

[0026] In the above structure, the material is squeezed by two sets of roller assemblies 603, and the roller assemblies 603 are covered by a protective chamber 604 to prevent the material from overflowing outside the protective chamber 604.

[0027] In a preferred embodiment: the roller assembly 603 includes a roller body 6031, a plurality of connecting tubes 6036 are annularly embedded in the inner cavity of the roller body 6031 along the axial direction, and a fixing rod 6035 is fixedly assembled at both ends of the connecting tubes 6036. A sliding groove 6032 is opened on the outer wall of the middle part of the roller body 6031. An abutment rod 6034 is sleeved on the side of the fixing rod 6035 away from the axis of the roller body 6031, and a tension spring 6033 is sleeved on the outer wall of the fixing rod 6035. The two ends of the tension spring 6033 are fixedly assembled with the inner wall of the end of the slide groove 6032 and the end of the abutment rod 6034, respectively. The inner cavity of the fixing rod 6035 and the abutment rod 6034 are connected and located on both sides of the roller body 6031. The inner cavity formed by the fixing rod 6035 and the abutment rod 6034 is connected by the connecting pipe 6036.

[0028] In the above structure, the inner cavity formed by the fixing rod 6035 and the abutment rod 6034 on both sides of the roller body 6031 is connected by the connecting pipe 6036. When the abutment rod 6034 is squeezed, the medium in the inner cavity formed by the fixing rod 6035 and the abutment rod 6034 on one side can be transmitted through the connecting pipe 6036 to the inner cavity formed by the fixing rod 6035 and the abutment rod 6034 on the other side, thereby enabling the abutment rod 6034 to extend and retract. The tension spring 6033 is fixedly assembled with the inner wall of the end of the slide groove 6032 and the end of the abutment rod 6034 respectively, so that the tension spring 6033 pulls the abutment rod 6034, so that when there is no external force to squeeze the abutment rod 6034, both abutment rods 6034 are subjected to force through the tension spring 6033. While one set of fixing rods 6035 and abutting rods 6034 are compressed, another set of abutting rods 6034 extends and retracts. After the compression of the abutment rod 6034 ends, the tension spring 6033 pulls the abutment rod 6034, causing the abutment rod 6034 to contract. By utilizing the contraction and extension process of the abutment rod 6034, the material adhering to the outer wall of the abutment rod 6034 is removed by scraping the abutment rod 6034 against the inner wall of the chute 6032.

[0029] In a preferred embodiment: the abutment component 606 includes a movable frame 6061, bolts 6062 are rotatably sleeved on the outer walls of both ends of the movable frame 6061, a U-shaped frame 6063 is threadedly connected to the outer wall of the bolts 6062, a first abutment shaft 6064 is rotatably connected to the inner wall of the movable frame 6061 near the roller assembly 603, a second abutment shaft 6065 is fixedly mounted on both outer walls of the first abutment shaft 6064, and a cleaning brush 6066 is fixedly mounted on the bottom outer wall of the movable frame 6061 near the roller assembly 603; The first abutting shaft 6064 is located between two sets of abutting rods 6034 on the same axis, and the outer wall of the first abutting shaft 6064 overlaps with the outer wall of the roller body 6031, and the outer wall of the second abutting shaft 6065 overlaps with the end of the abutting rod 6034. The outer wall of the C-shaped frame 6063 and the protective cabin 604 are fixedly assembled.

[0030] In the above structure, when a large amount of material accumulates in the middle of the two sets of roller assemblies 603, causing excessive force on the middle of the roller assembly 603, the force in the middle of the roller assembly 603 can be transmitted to the first abutment shaft 6064 by overlapping the outer wall of the first abutment shaft 6064 and the outer wall of the roller body 6031, thereby increasing the service life of the roller assembly 603. The outer wall of the second abutment shaft 6065 overlaps with the end of the abutment rod 6034, so that when the roller assembly 603 rotates, its abutment rod 6034 is in contact with the second abutment shaft 6065, so that the second abutment shaft 6065 squeezes the abutment rod 6034. By setting the abutment assembly 606 on both sides of the two sets of roller assemblies 603, the abutment rod 6034 located at the adjacent position of the two sets of roller assemblies 603 can be extended and retracted after the second abutment shaft 6065 squeezes the abutment rod 6034. By extending and retracting the abutment rods 6034 at adjacent positions of the two sets of roller assemblies 603, further compression of the material located between the two sets of roller assemblies 603 can be achieved. By rotating the bolt 6062 and the movable frame 6061 together, and by using the C-shaped frame 6063 and the outer wall of the protective chamber 604 for fixed assembly, the position of the movable frame 6061 can be changed by rotating the bolt 6062, thereby changing the pressure between the second abutting shaft 6065 and the abutting rod 6034.

[0031] In a preferred embodiment: the frame 4 includes a vertical plate 401, a connecting plate 402 is fixedly assembled on the inner wall of the vertical plate 401, a connecting plate 403 is fixedly assembled on the top of the vertical plate 401, and the roller pressing assembly 6 is located between the two sets of vertical plates 401.

[0032] In a preferred embodiment: the material assembly 5 includes a material rack 501, a first guide plate 502 is fixedly mounted on the bottom inner wall of the material rack 501, and a second guide plate 503 is fixedly mounted on the top inner wall of the first guide plate 502.

[0033] In the above structure, the flow of material is guided by the guide plate 502 arranged along the axial direction of the roller assembly 603, and the material is further dispersed by the several guide plates 503 arranged on the top of the guide plate 502, so that the material is distributed along the axial direction of the roller assembly 603.

[0034] A cement roller pressing method using a cement roller press includes the following steps: Step S1: Connect the input end of the gearbox 203 to the input end of the roller assembly 603, and drive the roller assembly 603 to rotate through the drive assembly 2; Step S2: The flow of material is guided by the guide plate 502 arranged along the axis of the roller assembly 603, and the material is further dispersed by the several guide plates 503 arranged on the top of the guide plate 502, so that the material is distributed along the axis of the roller assembly 603. Step S3: By setting the abutment component 606 on both sides of the two sets of roller assemblies 603, the second abutment shaft 6065 squeezes the abutment rod 6034. The inner cavity formed by the fixing rod 6035 and the abutment rod 6034 on both sides of the roller body 6031 is connected by the connecting pipe 6036. The medium in the inner cavity formed by the fixing rod 6035 and the abutment rod 6034 can be transmitted to the inner cavity formed by the other set of fixing rod 6035 and the abutment rod 6034 through the connecting pipe 6036, thereby extending and retracting the abutment rod 6034 at the adjacent positions of the two sets of roller assemblies 603, and further squeezing the material between the two sets of roller assemblies 603. Step S4: The two ends of the tension spring 6033 are fixedly assembled with the inner wall of the end of the slide 6032 and the end of the abutment rod 6034, respectively, so that the tension spring 6033 pulls the abutment rod 6034. After the abutment rod 6034 is compressed, the tension spring 6033 pulls the abutment rod 6034, causing the abutment rod 6034 to contract. By utilizing the contraction and extension process of the abutment rod 6034, the material adhering to the outer wall of the abutment rod 6034 is removed by scraping the abutment rod 6034 against the inner wall of the slide 6032. Step S5: By overlapping the outer wall of the first abutment shaft 6064 and the outer wall of the roller body 6031, the force in the middle of the roller assembly 603 can be transmitted to the first abutment shaft 6064, thereby increasing the service life of the roller assembly 603. Step S6: After being squeezed by the roller assembly 603, the material is discharged through the bottom of the protective chamber 604.

Step S5: By overlapping the outer wall of the first abutting shaft (6064) and the outer wall of the roller body (6031), the force in the middle of the roller assembly (603) can be transmitted to the first abutting shaft (6064), thereby increasing the service life of the roller assembly (603). Step S6: After being squeezed by the roller assembly (603), the material is discharged through the bottom of the protective chamber (604).
