Description

Technical Field

[0001] This utility model relates to the field of petrochemical environmental protection equipment technology, and in particular to an arch-breaking disturbance device and a dehydration chamber. Background Technology

[0002] In the petrochemical industry, petroleum coke is typically water-jet cut and then mixed with water in a specific ratio to form a slurry. This slurry is then pumped into the silo from the top using a large slurry pump. After being injected into the silo, the slurry is dehydrated by a water separation element, and the water enters the drainage pipe. Solid petroleum coke gradually accumulates inside the silo. Once the silo is full, the petroleum coke is unloaded and loaded onto trucks through the bottom discharge port.

[0003] During the unloading process, the petroleum coke inside the silo frequently arches, preventing it from falling properly and causing unloading interruptions. Therefore, breaking the arch is necessary to restore normal unloading. Existing methods typically involve manually striking the silo wall with a sledgehammer. This method is labor-intensive, inefficient, and the impact energy is difficult to effectively transfer to the arched area, resulting in unsatisfactory arch-breaking effects. Furthermore, it can easily damage the silo structure, posing safety hazards and leading to frequent maintenance and increased costs.

[0004] In addition, existing methods of breaking arches involve installing vibrators on the silo walls. The vibration is mostly concentrated in the area near the silo walls and cannot reach the deep arched parts in the center of the silo. This results in unsatisfactory arch-breaking effects, and long-term vibration can easily damage the silo structure, posing safety hazards and leading to frequent maintenance and increased costs.

[0005] In summary, existing methods of breaking arches generally suffer from problems such as being unfriendly to the silo structure, having unsatisfactory arch-breaking effects, posing safety hazards, and increasing maintenance costs. Utility Model Content

[0006] To address the technical problems of existing arch-breaking methods, such as being incompatible with the silo structure, having unsatisfactory arch-breaking effects, posing safety hazards, and increasing maintenance costs, this utility model provides an arch-breaking disturbance device that can effectively break arches without damaging the silo structure.

[0007] An arch-breaking disturbance device, comprising: A rotating spindle, the working end of which is equipped with an arch breaker; A rotary drive mechanism, the output end of which is connected to the rotary spindle, is used to drive the rotary spindle to rotate around its own axis; The lifting spindle is connected to the rotating spindle via a bearing housing; A lifting drive mechanism includes a lead screw, a nut, and a drive device. The lead screw passes through the nut, and the drive device is connected to the nut to drive the nut to rotate forward or in reverse. One end of the lead screw near the lifting main shaft is connected to the lifting main shaft. The drive device drives the nut to rotate forward or backward, thereby causing the lead screw to rise or fall, which in turn causes the lifting spindle and the rotating spindle to rise or fall, so that the arch breaker follows the rotating spindle to rise or fall.

The lifting main shaft 13 is connected to the upper end of the bearing seat 15. The lifting drive mechanism 14 includes a lead screw 141, a nut 142 and a drive device. The lead screw 141 passes through the nut 142. The drive device is connected to the nut 142 to drive the nut 142 to rotate forward or backward. The end of the lead screw 141 near the lifting main shaft 13 is connected to the lifting main shaft 13. The drive device drives the nut 142 to rotate forward or backward, thereby driving the lead screw 141 to rise or fall, and in turn driving the lifting main shaft 13 and the rotating main shaft 11 to rise or fall, so that the arch breaker follows the rotating main shaft 11 to rise or fall.

[0025] In this embodiment, the arch-breaking disturbance device 10 includes a rotating main shaft 11, a rotating drive mechanism 12, a lifting main shaft 13, and a lifting drive mechanism 14; the working end 111 of the rotating main shaft 11 is provided with an arch breaker; the output end of the rotating drive mechanism 12 is connected to the rotating main shaft 11 and is used to drive the rotating main shaft 11 to rotate around its own axis; the lifting main shaft 13 is connected to the rotating main shaft 11 through a bearing seat 15; the lifting drive mechanism 14 includes a lead screw 141, a nut 142, and a drive device, the lead screw 141 passes through the nut 142, the drive device is connected to the nut 142 to drive the nut 142 to rotate forward or backward, and the end of the lead screw 141 near the lifting main shaft 13 is connected to the lifting main shaft 13. During operation, the rotary drive mechanism 12 drives the rotary spindle 11 to rotate around its own axis to break the arch. The drive device drives the nut 142 to rotate forward or backward, thereby raising or lowering the lead screw 141, which in turn raises or lowers the lifting spindle 13 and the rotary spindle 11 as a whole, thus achieving the vertical adjustment of the arch breaker within the silo 20. The arch-breaking disturbance device 10 does not exert destructive external forces on the structure of the silo 20 during arch breaking, making it structurally friendly and effectively reducing safety hazards caused by damage to the silo 20 structure, as well as reducing maintenance frequency and costs. Furthermore, the arch breaker extends into the silo 20, and its working height is adjustable. It can be adjusted to the corresponding position according to the height of the arched part before operation, thereby achieving a good arch-breaking effect.

[0026] It should be further noted that the arch breaker can be, but is not limited to, the following structure. The arch breaker includes an arch-breaking shaft and blades disposed on the arch-breaking shaft. The blades rotate to break up the petroleum coke within the silo 20.

[0027] In some optional embodiments, the drive device includes a first geared motor 143 and a gear assembly; the gear assembly includes a pinion 144 and a gear 145 meshing together, the output shaft of the first geared motor 143 is connected to the pinion 144, and the nut 142 is connected to the gear 145. The first geared motor 143 is an assembly composed of a first motor 1431 and a first reducer 1432. The first geared motor 143 can operate smoothly and continuously, thereby ensuring the long-term stable operation of the nut 142 and the lead screw 141.

[0028] In some alternative embodiments, the nut 142 is coaxially arranged with the large gear 145. Specifically, the nut 142 is located at the center of the large gear 145 and is fixedly connected to the large gear 145.

[0029] In some alternative embodiments, the drive device includes a handwheel 146, and a nut 142 is coaxially arranged with the handwheel 146. Specifically, the nut 142 is located at the center of the handwheel 146 and is fixedly connected to the handwheel 146.

[0030] In some optional embodiments, the rotary drive mechanism 12 includes a second geared motor 121, a drive gear 122, and a driven gear 123; the drive gear 122 is connected to the output shaft of the second geared motor 121; the driven gear 123 meshes with the drive gear 122 and is connected to the rotary spindle 11. The second geared motor 121 is an assembly consisting of a second motor 1211 and a second gear reducer 1212.

[0031] In some alternative embodiments, the rotary drive mechanism 12 further includes a gearbox 124, in which a driven gear 123 and a driving gear 122 are mounted, and a second geared motor 121 is disposed outside the gearbox 124, with its output shaft passing through the gearbox 124 and connected to the driving gear 122.

[0032] The working mechanism of the arch-breaking and disturbance device 10 is as follows: When arch breaking is required, the second reduction motor 121 is started, which drives the driven gear 123 meshing with it to rotate through the driving gear 122, thereby driving the rotating main shaft 11 to rotate. The rotating main shaft 11 drives the arch-breaking device connected to it to rotate synchronously, disturbing the petroleum coke in the silo 20 and restoring the petroleum coke to normal unloading. When the arching position is not at a single height and the disturbance layer needs to be changed, the first reduction motor 143 is started, which drives the large gear 145 meshing with it to rotate through the small gear 144, thereby driving the nut 142 coaxial with the large gear 145 to rotate forward or reverse, so that the lead screw 141 can move linearly up and down, and drive the lifting main shaft 13 connected to the lead screw 141 and the rotating main shaft 11 coaxially set up to rise or fall as a whole, so that the arch-breaking device can rotate and disturb after being adjusted at different heights in the silo 20. It is worth noting that when the arching position is not at a single height and the disturbance layer needs to be changed, the handwheel 146 can be manually rotated to drive the nut 142, which is coaxial with the handwheel 146, to rotate forward or reverse. This allows the lead screw 141 to move linearly up and down, and drives the lifting main shaft 13 connected to the lead screw 141 and the rotating main shaft 11, which are coaxially arranged, to rise or fall as a whole. This allows the arch breaker to rotate and disturb after being adjusted at different heights in the chamber 20.

[0033] In some optional embodiments, the arch-breaking disturbance device 10 further includes a housing assembly 16, which includes an upper housing 161, a middle housing 162, and a lower housing 163; a lifting spindle 13 is disposed inside the upper housing 161; the top end of the middle housing 162 is connected to the bottom end of the upper housing 161; one end of the lower housing 163 is connected to the bottom end of the middle housing 162, and the other end is connected to the gearbox 124; a rotating spindle 11 is disposed inside the middle housing 162 and extends downward through the lower housing 163 and the gearbox 124 in sequence.

[0034] In some alternative embodiments, the top of the gearbox 124 is provided with a mounting hole 1241, and the output shaft of the second reduction motor 121 passes through the mounting hole 1241 and is connected to the drive gear 122 installed in the gearbox 124.

[0035] In some alternative embodiments, the lower housing 163 is flared, the gearbox 124 has an opening 1242 at the top that matches the bottom of the lower housing 163, and the bottom of the lower housing 163 is installed at the opening 1242; the bottom of the gearbox 124 has a through hole for the rotating spindle 11 to pass through.

[0036] In some optional embodiments, the outer wall of the upper housing 161 is provided with a mounting bracket 17, and the first reduction motor 143 is fixed to the outer wall of the upper housing 161 through the mounting bracket 17, so that the pinion 144, the gear 145 and the nut 142 are limited in the vertical direction, that is, the nut 142 rotates with the gear 145, but does not move in the vertical direction.

[0037] In some optional embodiments, the arch-breaking disturbance device 10 further includes a guide sleeve 18 through which the lifting main shaft 13 passes. By passing the lifting main shaft 13 through the guide sleeve 18, the possible deviation of the lifting main shaft 13 during operation can be effectively reduced, allowing the lifting main shaft 13 to operate smoothly.

[0038] In addition, please see the appendix. Figure 7 As shown, one embodiment of this utility model also provides a dehydration chamber, including a chamber body 20 and an arch-breaking disturbance device 10 as described in any of the above embodiments. The arch-breaking disturbance device 10 is installed on the top of the chamber body 20, and the arch-breaking device extends into the interior of the chamber body 20. Since the dehydration chamber includes the arch-breaking disturbance device 10 as described in any of the above embodiments, it at least possesses the technical effects of the arch-breaking disturbance device 10, which will not be elaborated further here.
