Description

Technical Field

[0001] This utility model relates to the field of cement processing equipment technology, and in particular to a cement roller press that prevents roller shaft breakage. Background Technology

[0002] Cement roller press is a key piece of equipment in the cement production process. It uses two relatively rotating rollers to squeeze the material. The material is fed from above the two rollers and continuously carried into the space between the rollers. Under high pressure, the larger particles are squeezed and crushed first. As the material moves downward, the pressure increases and the density of the material layer increases. Smaller particles are also crushed until the narrowest part between the two rollers, where it becomes a dense cake that is discharged from the bottom of the machine.

[0003] During operation, the roller bearings of a cement roller press are subjected to enormous pressure and impact loads. Furthermore, the friction between the material and the rollers can cause the roller shaft temperature to rise, making it prone to breakage and severely impacting production efficiency and equipment lifespan.

[0004] Therefore, to address the above problems, a cement roller press designed to prevent roller breakage can be constructed. By incorporating a cooling mechanism and a buffer mechanism inside the roller, the buffer mechanism effectively disperses the pressure on the roller, while the cooling mechanism effectively prevents the roller from overheating, thus significantly reducing the risk of roller breakage. Utility Model Content

[0005] To overcome the problem that during the operation of cement roller presses, the roller bearings are subjected to huge pressure and impact loads, and the friction between the material and the rollers also causes the roller shaft temperature to rise, which can easily lead to roller shaft breakage, seriously affecting production efficiency and equipment service life.

[0006] The technical solution of this utility model is as follows: a cement roller press for preventing roller shaft breakage, comprising a housing, a movable roller, a fixed roller, a roller shaft, a circulating water hole, a sealed bearing, an outer connecting pipe, a buffer assembly, an adjustment assembly, and a drive assembly. Roller shafts are fixedly installed inside both the movable roller and the fixed roller. The fixed roller is rotatably connected to the inside of the housing through the roller shaft. The movable roller is connected to the adjustment assembly through the roller shaft and is located on one side of the fixed roller. The buffer assembly is located inside the roller shaft. A circulating water hole is opened at one end of the roller shaft. The outer connecting pipe is located outside the opening of the circulating water hole and is rotatably connected to the roller shaft through the sealed bearing. The drive assembly is located at the other end of the roller shaft.

[0007] Preferably, a drive assembly is used to drive the fixed and movable rollers to rotate, extruding the material. An adjustment assembly is used to adjust the distance between the fixed and movable rollers to adapt to different processing requirements. A buffer assembly is used to absorb the pressure and impact on the rollers during normal operation. A sealed bearing is used to stably connect the outer pipe to the rollers, and the outer pipe is connected to an external circulating water supply device to deliver circulating cooling water to the circulating water holes inside the rollers, thereby removing the heat generated by the extrusion operation, ensuring that the rollers are adequately cooled during operation, and reducing the risk of roller breakage.

[0008] Preferably, the inner wall of the circulating water hole is provided with a stress dispersion groove, which has a spiral structure.

[0009] Preferably, the buffer assembly includes multiple sets of axial through holes, which are evenly arranged circumferentially around the axis of the roller.

[0010] Preferably, the axial through hole is filled with damping filler, which is made of metal rubber.

[0011] Preferably, a feeding hopper is connected to the upper end of the casing, and a discharge port is connected to the lower end of the casing.

[0012] Preferably, the adjustment assembly includes a hydraulic rod and a slider. The slider is slidably connected inside the machine housing, the roller shaft inside the movable roller is rotatably connected to the slider, the hydraulic rod is fixedly installed on one side of the machine housing, and the output end of the hydraulic rod is fixedly connected to the slider.

[0013] Preferably, the drive assembly includes a geared motor and a coupler, with the geared motor located at one end of the roller shaft and the output end of the geared motor connected to the roller shaft via the coupler.

[0014] The beneficial effects of this utility model are:

[0015] When the roller press is operating stably, the outer pipe is stably connected to the roller shaft through a sealed bearing. The outer pipe is then connected to an external circulating water supply system, which supplies circulating cooling water to the circulating water holes inside the roller shaft. The stress dispersion grooves inside the circulating water holes can disperse the pressure on the roller shaft and increase the contact area between the inner wall of the circulating water holes and the cooling circulating water, making the heat exchange between the roller shaft and the cooling water more efficient. This ensures that the roller shaft is adequately cooled during operation and reduces the risk of roller shaft breakage. The multiple sets of axial through holes inside the roller shaft provide deformation space for thermal expansion and contraction. At the same time, the damping filler made of metal rubber material filled inside the axial through holes can absorb the vibration and impact generated during operation, ensuring stable operation of the roller shaft and effectively reducing the risk of roller shaft breakage.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a cement roller press for preventing roller shaft breakage, comprising a housing 1, a movable roller 2, a fixed roller 3, a roller shaft 4, a circulating water hole 401, a sealed bearing 402, an outer connecting pipe 403, a buffer assembly, an adjustment assembly, and a drive assembly. Roller shafts 4 are fixedly installed inside both the movable roller 2 and the fixed roller 3. The fixed roller 3 is rotatably connected to the inside of the housing 1 via roller shafts 4. The movable roller 2 is connected to the adjustment assembly via roller shafts 4 and is located on one side of the fixed roller 3. The buffer assembly is disposed inside the roller shaft 4. A circulating water hole 401 is opened at one end of the roller shaft 4. The outer connecting pipe 403 is disposed around the opening of the circulating water hole 401 and is rotatably connected to the roller shaft 4 via the sealed bearing 402. The drive assembly is located at the other end of the roller 4. By setting the drive assembly, the roller 4 drives the fixed roller 3 and the movable roller 2 to rotate, extruding the material. The distance between the fixed roller 3 and the movable roller 2 can be adjusted by setting the adjustment assembly to adapt to different processing requirements. The buffer assembly can absorb the pressure and impact on the roller 4 during normal operation. The sealed bearing 402 is used to stably connect the outer pipe 403 to the roller 4. The outer pipe 403 is connected to an external circulating water supply device to deliver circulating cooling water to the circulating water holes 401 inside the roller 4, thereby removing the heat generated by the extrusion operation, ensuring that the roller 4 is fully cooled during operation, and reducing the risk of roller 4 breakage.

[0023] Please see Figure 3 and Figure 4 In this embodiment, the inner wall of the circulating water hole 401 is provided with a stress dispersion groove 404, which has a spiral structure. By setting the stress dispersion groove 404, the pressure on the roller 4 can be dispersed, and the contact area between the inner wall of the circulating water hole 401 and the cooling circulating water can be increased, making the heat exchange between the roller 4 and the cooling water more efficient. The buffer assembly includes multiple sets of axial through holes 405, which are evenly arranged circumferentially around the axis of the roller 4. The axial through holes 405 are filled with damping filler, which is made of metal rubber. By setting the axial through holes 405, deformation space can be provided for the thermal expansion and contraction of the roller 4. At the same time, the damping filler made of metal rubber filled inside the axial through holes 405 can absorb vibration and impact generated during operation.

[0024] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, a feeding hopper 101 is connected to the upper end of the housing 1, and a discharge port 102 is connected to the lower end of the housing 1. The feeding hopper 101 allows raw materials to be added to the inside of the housing 1, and the discharge port 102 allows the extruded material to be discharged. The adjusting assembly includes a hydraulic rod 501 and a slider 502. The slider 502 is slidably connected to the inside of the housing 1, and the roller shaft 4 inside the movable roller 2 is rotatably connected to the slider 502. The hydraulic rod 501 is fixedly installed on one side of the housing 1, and the output end of the hydraulic rod 501 is fixedly connected to the slider 502. The roller 2 and the fixed roller 3 are connected by a hydraulic rod 501, which can push the slider 502 to slide inside the housing 1, thereby adjusting the distance between the movable roller 2 and the fixed roller 3. The drive assembly includes a geared motor 601 and a coupler 602. The geared motor 601 is located at one end of the roller shaft 4, and the output end of the geared motor 601 is connected to the roller shaft 4 through the coupler 602. The geared motor 601 can stably drive the roller shaft 4 to rotate, and the coupler 602 can prevent the geared motor 601 from being overloaded, thus providing a certain degree of protection for the roller shaft 4 and the geared motor 601.

[0025] During operation, the hydraulic rod 501 can be used to push the slider 502 to slide inside the machine housing 1, adjusting the distance between the movable roller 2 and the fixed roller 3. After adjustment, the geared motor 601 can stably drive the roller shaft 4 to rotate, and the feeding hopper 101 can be used to add raw materials to the inside of the machine housing 1.

[0026] During stable operation, the sealed bearing 402 is used to stably connect the outer pipe 403 to the roller 4, thereby connecting the outer pipe 403 to the external circulating water supply equipment to supply circulating cooling water to the circulating water hole 401 inside the roller 4. The stress dispersion groove 404 opened inside the circulating water hole 401 disperses the pressure on the roller 4, and at the same time increases the contact area between the inner wall of the circulating water hole 401 and the cooling circulating water, making the heat exchange between the roller 4 and the cooling water more efficient, ensuring that the roller 4 is fully cooled during operation, and reducing the risk of roller 4 breakage.

[0027] The multiple sets of axial through holes 405 inside the roller 4 provide deformation space for thermal expansion and contraction of the roller 4. At the same time, the damping filler made of metal rubber material inside the axial through holes 405 can absorb the vibration and impact generated during operation, ensuring the stable operation of the roller 4 and effectively reducing the risk of roller 4 breakage.

[0028] Through the above steps, the buffer assembly can absorb the pressure and impact on the roller 4 during normal operation. By setting a sealed bearing 402, a stable connection is made between the outer pipe 403 and the roller 4. The outer pipe 403 is connected to an external circulating water supply device to deliver circulating cooling water to the circulating water holes 401 inside the roller 4, thereby removing the heat generated by the extrusion operation and ensuring that the roller 4 is adequately cooled during operation, reducing the risk of roller 4 breakage. This solves the problem that during the operation of the cement roller press, the roller 4 is subjected to huge pressure and impact loads, and the friction between the material and the roller also causes the temperature of the roller 4 to rise, which makes the roller 4 prone to breakage, seriously affecting production efficiency and equipment service life.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
