Description

Technical Field

[0001] This utility model relates to the field of petroleum refining equipment technology, specifically an adjustable roller crusher. Background Technology

[0002] In a closed coking system, the core task of the roller crusher is to crush large pieces of coke to the uniform particle size required for subsequent processes. However, the crushing effect of the roller crusher depends entirely on the roller gap (the distance between the two rollers). The roller gap determines the maximum particle size of the crushed material. If the roller gap cannot be adapted to the material characteristics and process requirements, it will directly lead to crushing failure, which in turn affects the operation of the entire closed coking system.

[0003] Traditional roller crushers generally use manual adjustment of the roller gap (such as adjusting the gap by turning the adjusting screw with a wrench, adjusting the shims, etc.), which is fundamentally contradictory to the "environmental protection, safety, and continuous operation" requirements of closed decoking. 1. Unable to adapt to material fluctuations The particle size and hardness of coke materials (such as petroleum coke) fluctuate from batch to batch (e.g., when coke is discharged from a delayed coking unit, the size of the coke blocks is uneven), and manual adjustment cannot respond in real time.

[0004] 2. Relies on manual labor and is inefficient Manual inspection is required to determine whether the crushed particle size meets the standard, and then the machine must be stopped for adjustment, which takes a long time.

[0005] 3. High energy consumption and equipment wear and tear Delayed roller gap adjustment can lead to either "over-crushing" (too small roller gap, resulting in too much fine powder) or "under-crushing" (too large roller gap, resulting in uneven load). Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0021] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] Example 1 See Figures 1-4 This embodiment provides an adjustable roller crusher, including a base 1, a movable frame 2, a first drive member 3, a second drive member 4, a fixed roller 5, and a movable roller 6. The movable frame 2 is slidably connected to the base 1. One end of the first drive member 3 is installed on the outer wall of the movable frame 2, and the other end of the first drive member 3 extends out of the outer wall of the base 1, driving the movable frame 2 to slide. The fixed roller 5 is installed in the base 1, and the movable roller 6 is installed on the movable frame 2. The axis of the fixed roller 5 and the axis of the movable roller 6 are located in the same plane and are parallel to each other. The first drive member 3 controls the movable roller 6 to move closer to or away from the fixed roller 5. Both the fixed roller 5 and the movable roller 6 are connected to a second drive member 4.

[0023] For example, the second driving member 4 connected to the fixed roller 5 and the second driving member 4 connected to the movable roller 6 are arranged in a mirror-off staggered manner, and the rotation of the fixed roller 5 and the movable roller 6 is controlled by the second driving member 4; while the second driving member 4 is located outside the base 1.

[0024] For example, the first driving component 3 is a hydraulic cylinder, and the second driving component 4 is a motor; furthermore, the first driving component 3 is a spring-return hydraulic cylinder.

[0025] It should be noted that the first drive component 3 has a built-in pressure sensor (not shown in the figure); the second drive component 4 is equipped with a torque sensor 41; the first drive component 3, the second drive component 4, the pressure sensor, and the torque sensor 41 are all connected to the controller signal. By monitoring the crusher's operating parameters in real time (such as the hydraulic pressure of the first drive component 3 and the current of the second drive component 4), the gap between the movable roller 6 and the fixed roller 5 is dynamically adjusted to adapt to changes in material characteristics. For example, the pressure sensor monitors the extrusion pressure between the movable roller 6 and the fixed roller 5 in real time. When the material hardness increases (such as encountering hard spots in coke), the pressure of the first drive component 3 can be automatically increased to maintain the crushing effect. Conversely, when the material softens, the pressure of the first drive component 3 is reduced to avoid over-crushing. For example, the torque sensor 41 monitors the torque of the second drive component 4 in real time. When the output torque of the second drive component 4 is detected to be too high, the controller can control the second drive component 4 to reverse, reduce the roller speed (such as the fixed roller 5 and the movable roller 6), and adjust the roller gap of the first drive component 3 to remove foreign objects. At the same time, the torque sensor 41 is set to prevent instantaneous impact from damaging the equipment, so that the particle size of the material can meet the standard.

[0026] See Figures 1-5 In the specific implementation process, the base 1 is provided with a guide rail 11 to match the slider 21 provided at the bottom of the movable frame 2, thereby enabling the movable frame 2 to drive the movable roller 6 to move, so as to adjust the gap between the movable roller 6 and the fixed roller 5.

[0027] Furthermore, the movable frame 2 has a U-shaped cross-section, with the opening of the U-shape facing the fixed roller 5; the bottom ends of the two vertical sides of the U-shape are provided with the sliders 21, and the working end of the first driving member 3 is connected to the horizontal side of the U-shape to push the movable frame 2 away from or closer to the fixed roller 5.

[0028] It should be noted that the movable roller 6 is installed inside the opening of the U-shape, and the two ends of the movable roller 6 pass through the two vertical sides of the U-shape respectively. When the movable frame 2 slides along the sliding rod of the base 1, the movable roller 6 is moved accordingly.

[0029] Furthermore, first bearing seats 22 are installed on both sides of the movable frame 2, and the shaft on the movable roller 6 is connected to the first bearing seats 22 through bearings, so that when the movable roller 6 is working, the movable frame 2 does not rotate with the movable roller 6, and at the same time, the stability of the movable roller 6 is improved.

[0030] In the specific implementation process, a second bearing seat 12 is installed on each of the two symmetrical side walls of the base 1. The shaft on the fixed roller 5 is connected to the second bearing seat 12 through the bearing, so that when the fixed roller 5 is working, the base 1 does not rotate with the fixed roller 5, which also improves the stability of the fixed roller 5.

[0031] See Figures 1-4 In the specific implementation process, the base 1 includes a base 13 enclosing a box structure, a front side plate 14, a rear side plate 15, a left side plate 16, a right side plate 17, and a cover plate 18; the lower ends of the front side plate 14, the rear side plate 15, the left side plate 16, and the right side plate 17 are all vertically fixed to the upper end surface of the base 13, and the upper ends of the front side plate 14, the rear side plate 15, the left side plate 16, and the right side plate 17 are all vertically fixed to the lower end surface of the cover plate 18; the front side plate 14 and the rear side plate 15 are each provided with a first opening 141 for fitting and installing the movable frame 2; and the guide rail 11 is provided on the upper end surface of the base 13 at a position corresponding to the first opening 141.

[0032] It should be noted that the second bearing seat 12 is installed on both the front side plate 14 and the rear side plate 15; at the same time, the second driving member 4 is provided on the outer side of both the front side plate 14 and the rear side plate 15. For example, the output shaft of one second driving member 4 is connected to the movable roller 6 through a bearing, and the output shaft of the other second driving member 4 is connected to the fixed roller 5 through a bearing.

[0033] Furthermore, a second opening 161 is provided on the left side plate 16; a first mounting member 162 is provided on the outer side wall of the left side plate 16, one end of the first driving member 3 is provided on the first mounting member 162, and the other end of the first driving member 3 passes through the second opening 161 and is provided on the outer side wall of the movable frame 2 through the second mounting member 163.

[0034] See Figure 6 For example, the first mounting component 162 includes two symmetrically spaced first support plates 162a and a first connecting shaft 162b. The two first support plates 162a are connected by the first connecting shaft 162b, and one end of the first driving component 3 is provided with an opening to be sleeved on the first connecting shaft 162b, so that the first driving component 3 is located between the two first support plates 162a.

[0035] For example, the second mounting component 163 includes a fixed plate 163a, two second support plates 163b, and a second connecting shaft 163c. The fixed plate 163a is fixed to the outer wall of the movable frame 2. The two second support plates 163b are symmetrically spaced on the fixed plate 163a at one end face away from the movable frame 2 and are connected by the second connecting shaft 163c. The end of the first driving component 3 facing away from the first mounting component 162 is sleeved on the second connecting shaft 163c and is located between the two second support plates 163b. This structure allows the telescopic end of the first driving component 3 to pull the movable frame 2 back and forth in a straight line along the base 1 to adjust the gap between the fixed roller 5 and the movable roller 6.

[0036] For example, the movable frame 2 is located below the cover plate 18, and there is a gap between the upper end face of the movable frame 2 and the bottom end face of the cover plate 18, which facilitates the sliding of the movable frame 2.

[0037] See Figure 3 , Figure 5 The second driving member 4, which is connected to the movable roller 6, is mounted on the suspension member 19 fixed to the outer wall of the movable frame 2, and the bottom end face of the suspension plate 19 is located above the bottom end face of the base 1, so that when the movable frame 2 and the movable roller 6 move, the second driving member 4 connected to the movable roller 6 also moves accordingly.

[0038] For example, the longitudinal section of the suspension member 19 is Z-shaped, and the end of the upper horizontal side of the Z-shape is fixed to the outer wall of the movable frame 2. The upper part of the plane where the lower horizontal side of the Z-shape is located is used to support the second driving member 4, and there is a gap between the lower part of the plane where the lower horizontal side of the Z-shape is located and the bottom end face of the base 1. That is, the suspension member 19 is suspended relative to the base 13.

[0039] See Figure 1 , Figure 2 In the specific implementation process, the cover plate 18 is provided with a third opening 181, and the fixed roller 5 and the movable roller 6 are both exposed in the third opening 181, which facilitates observation of the working status of the fixed roller 5 and the movable roller 6, and also facilitates the addition of materials.

[0040] It should be noted that, in order to facilitate the collection of crushed materials, the base 13 is provided with a fourth opening 131, and the movable roller 6 and the fixed roller 5 are exposed in the fourth opening 131.

[0041] This utility model is implemented as follows: 1. When encountering hard burn: The pressure sensor monitors the extrusion pressure between the movable roller 6 and the fixed roller 5 in real time. When the pressure is detected to be too low or too high, the pressure of the first drive component 3 is adjusted to maintain the crushing effect. 2. When encountering large pieces of burnt material: If the torque sensor 41 detects that the output torque is too large, it will feed the signal back to the controller. The controller will then control the first drive component 3 to work, thereby increasing the gap between the movable roller 6 and the fixed roller 5.

[0042] 3. When encountering extra-large coke blocks (larger than the coke block sizes mentioned in point 2 above): The pressure sensor detects that the compressive force between the movable roller 6 and the fixed roller 5 is lower than the set value, and the torque sensor 41 detects that the torque of the second drive component 4 is lower than the reference value. At the same time, the upstream sensor of the crusher detects that there is material or that a blockage has occurred. Then the controller controls the gap between the movable roller 6 and the fixed roller 5 to increase through the first drive component 3, and adjusts the roller speed of the movable roller 6 and the fixed roller 5 so that the movable roller 6 and the fixed roller 5 rotate at different speeds.

[0043] 4. When the crusher jams: If the torque sensor 41 detects that the torque of the second drive component 4 is too large, the torque limiter on the second drive component 4 will automatically disengage, and the controller will control the second drive component 4 to reverse and remove the material.

[0044] This embodiment achieves roller spacing adjustment through structural design of movable rollers, first driving component, and movable frame, without requiring equipment shutdown and with high working efficiency.
