Description

Technical Field

[0001] The invention belongs to the technical field of petroleum coke particle size testing, and in particular relates to a continuous particle size monitoring device for petroleum coke. Background Art

[0002] Petroleum coke is a solid byproduct produced during the oil refining process, mainly from the delayed coking process of oil. It is a carbon-rich substance with the appearance of black particles or powder, with high energy content and low sulfur and nitrogen content.

[0003] During the use of petroleum coke, the particle size of petroleum coke directly affects its combustion, reaction and other properties. Too large or too small particles will lead to inconsistent physical and chemical properties, affecting the quality of the final product. For example, too coarse particles may not be easy to burn completely, resulting in reduced combustion efficiency; while too fine particles may increase resistance and be difficult to transport or handle. Therefore, it is necessary to monitor the particle size of the produced petroleum coke during use. The continuous particle size monitoring equipment can provide real-time feedback on the changes in the particle size distribution of petroleum coke during use, ensure the consistency of the product particle size, avoid the problem of low combustion efficiency due to particle size fluctuations, and achieve full utilization of energy.

[0004] However, the existing petroleum coke continuous particle size monitoring equipment still has the following technical problems in the process of monitoring petroleum coke: After the petroleum coke is produced, it needs to be stored, and when it is used, the stored petroleum coke must be directly transported and the particle size must be monitored, and the petroleum coke that meets the requirements must be burned and used. During the storage of petroleum coke, the moisture in the air can easily cause the petroleum coke to stick together, resulting in less petroleum coke that meets the requirements when the particle size of the petroleum coke is subsequently monitored, affecting the accuracy of the particle size monitoring of the petroleum coke. During the monitoring process of petroleum coke, petroleum cokes of different particle sizes will mix and accumulate at the monitoring location, further reducing the accuracy of petroleum coke particle size monitoring.

[0014] Compared with the existing technology, the advantages of this continuous particle size monitoring device for petroleum coke are: The present invention provides a fluidized drying mechanism. During the process of conveying and monitoring the particle size of petroleum coke, high-pressure gas is conveyed into an air guide box by an air compressor and further discharged through a plurality of exhaust slots. The petroleum coke particles are suspended and fluidized by air flow. The petroleum coke is dried and dispersed by the collision of the air flow and the petroleum coke, and moisture in the petroleum coke is removed, thereby preventing the petroleum coke from sticking together, improving the accuracy of monitoring the particle size of the petroleum coke, and avoiding mechanical contact damage to the petroleum coke, thereby ensuring the combustion efficiency of the petroleum coke during use.

The contact between the hot air flow and the petroleum coke improves the drying and dispersion effects of the petroleum coke.

[0016] The present invention provides a material leveling mechanism. Before the monitoring device monitors the petroleum coke, the driving assembly drives the rotating sleeve to rotate relative to the fixed rod, so that the rotating rod drives the stirring blades to rotate. The petroleum coke is broken up by the stirring blades before flowing to the bottom of the monitoring device, thereby improving the dispersion of the petroleum coke during the monitoring process, allowing the petroleum coke particles to maintain a stable flow state when being transported to the monitoring area, and reducing the accumulation and mutual interference of the petroleum coke particles.

[0017] The present invention provides a floating mechanism. During the process of suspending and fluidizing the petroleum coke, the reciprocating vertical displacement of the lifting rod can drive the threaded rod to perform reciprocating vertical displacement, thereby driving the baffles on both sides to reciprocate and move closer to and away from each other. The amount of air discharged from the exhaust holes on the baffles is lower than the amount of air discharged from other positions of the exhaust groove. The difference in air volume can cause the petroleum coke particles to float up and down during the process of suspending and fluidizing, thereby further improving the dispersion of the petroleum coke.

[0018] The present invention sets a driving assembly and a transmission assembly. When in use, the first motor can not only drive the material leveling mechanism to work through the gear and the first gear ring, but also drive the floating mechanism to work through the bevel gear set, the transmission rod, the cam and the transmission plate. There is no need to set an additional driving source, thus saving processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Example: Refer to Figures 1 to 7 , a continuous particle size monitoring device for petroleum coke, comprising: A monitoring box 1, wherein a partition 11 is fixedly connected inside the monitoring box 1, and the monitoring box 1 is divided into a transmission chamber 12 and a monitoring chamber 13 by the partition 11, and a conveying pipe 14 is fixedly connected to the inner top wall of the monitoring chamber 13, and the conveying pipe 14 communicates with the outside and the monitoring chamber 13, and a monitoring device 15 is fixedly connected to the inner top wall of the monitoring box 1; Specifically, the monitoring device 15 uses a commonly used laser detector, which is an existing mature technology and will not be described in detail here.

[0023] The fluidized drying mechanism 2 is used to transport the petroleum coke in a suspended fluidized state. The fluidized drying mechanism 2 includes an air guide box 21 fixedly connected to the inner bottom wall of the monitoring chamber 13. The upper end of the air guide box 21 is provided with a plurality of exhaust slots 22 distributed in a linear array. The bottom end of the monitoring box 1 is fixedly connected to an air compressor 23. The output end of the air compressor 23 is communicated with the inside of the air guide box 21. Specifically, the outlet direction of the exhaust groove 22 is at an angle of 30° to the horizontal, forming a spiral ascending airflow field, which can achieve a transportation effect on the petroleum coke while suspending and fluidizing the petroleum coke particles.

[0024] In view of the problem in the prior art that moisture in the air easily causes petroleum coke to stick together, resulting in a small amount of petroleum coke that meets the requirements when the particle size of the petroleum coke is subsequently monitored, affecting the accuracy of the particle size monitoring of the petroleum coke, the present invention provides a fluidized drying mechanism 2. During the transportation and particle size monitoring of the petroleum coke, the petroleum coke is transported to the monitoring box 1 through the delivery pipe 14, and then the high-pressure gas is transported to the air guide box 21 through the air compressor 23, and further discharged through a plurality of exhaust slots 22. The petroleum coke particles are suspended and fluidized by the air flow, and finally the particle size of the petroleum coke in the suspended and fluidized state is monitored by the monitoring device 15. The collision of the air flow and the petroleum coke can achieve drying and dispersion of the petroleum coke, remove moisture in the petroleum coke, thereby avoiding adhesion of the petroleum coke, improving the accuracy of the particle size monitoring of the petroleum coke, and avoiding mechanical contact damage to the petroleum coke, thereby ensuring the combustion efficiency of the petroleum coke during use.

[0025] A plurality of heating rods 24 distributed in a linear array are rotatably connected in the air guide box 21, a second motor 25 is fixedly connected to an outer wall of one side of the air guide box 21, an output end of the second motor 25 is fixedly connected to one of the heating rods 24, and a heat insulation layer is provided at the connection position between the output end of the second motor 25 and the heating rod 24, a plurality of the heating rods 24 are fixedly connected to a heat insulating guide rod 26 at one end away from the second motor 25, the plurality of the heat insulating guide rods 26 are connected by a chain drive, and the plurality of the heating rods 24 are connected in parallel to an external power source.

[0026] Specifically, the thermal insulation layer and the thermal insulation guide rod 26 are made of high-efficiency thermal insulation materials, such as vacuum insulation panels and graphene, which have excellent thermal insulation effects, ensuring that the thermal insulation layer and the thermal insulation guide rod 26 can effectively prevent heat transfer from the heating rod 24 and avoid high temperature from affecting the structure of the second motor 25 and the chain transmission part.

[0027] Specifically, a sealing plate is provided between the air guide box 21 and the partition 11 , and the sealing plate can prevent the petroleum coke from falling into the chain drive position of the plurality of heat-insulating guide rods 26 during transportation, thereby avoiding affecting the rotation of the plurality of heating rods 24 .

[0028] It is worth mentioning that the present invention provides heating rods 24. When the high-pressure gas flows through the air guide box 21, one of the heating rods 24 can be driven to rotate by the second motor 25, and multiple heating rods 24 can be driven to rotate synchronously by chain transmission, so as to evenly heat the high-pressure gas in the air guide box 21. The contact between the hot air flow and the petroleum coke improves the drying and dispersion effects of the petroleum coke.

[0029] The material leveling mechanism 3 is used to break up the petroleum coke during the petroleum coke transportation process. The material leveling mechanism 3 includes a rotating sleeve 31 that passes through and is rotatably connected to the upper wall of the monitoring box 1. The top of the monitoring box 1 is fixedly connected to an L-shaped plate 32, and the lower end of the L-shaped plate 32 is fixedly connected to a fixing rod 33. The fixing rod 33 extends into the rotating sleeve 31 and is fixedly connected to a first bevel gear 34. Two symmetrically distributed rotating rods 35 are rotatably connected to the circumferential side wall of the rotating sleeve 31. The part of the rotating rod 35 located in the rotating sleeve 31 is fixedly connected to a second bevel gear 36, and the second bevel gear 36 is meshed with the first bevel gear 34. The part of the rotating rod 35 located outside the rotating sleeve 31 is fixedly connected to a stirring blade 37. The upper end of the monitoring box 1 is provided with a driving assembly 38 for driving the rotating sleeve 31 to rotate relative to the fixing rod 33.

[0030] Specifically, the stirring blades 37 on the rotating sleeve 31 adopt a turbine structure, with a blade inclination angle of 15° and a rotation speed controlled at 500-1500rpm. The shear force generated by the rotation of the blades only acts within 100mm of the outlet of the conveying pipe 14, and will not affect the particle flow state in the monitored area, nor will it affect the suspension and transportation of the petroleum coke particles.

[0031] Specifically, the driving assembly 38 includes a first motor 381 fixedly connected to the upper end of the monitoring box 1, a gear 382 is fixedly connected to the output end of the first motor 381, and a first gear ring 383 is fixedly connected to the peripheral side wall of the rotating sleeve 31 located above the monitoring box 1, and the gear 382 and the first gear ring 383 are meshed with each other.

[0032] In view of the problem that petroleum coke in the prior art may be mixed and accumulated at the monitoring position, thereby further reducing the accuracy of monitoring the particle size of petroleum coke, the present invention provides a material leveling mechanism 3. Before the monitoring device 15 monitors the petroleum coke, the driving assembly 38 can drive the rotating sleeve 31 to rotate relative to the fixed rod 33, so that the rotating rod 35 on the rotating sleeve 31 performs a circular motion along the fixed rod 33, and in this process, the second bevel gear 36 is driven to rotate by the fixed first bevel gear 34, so that the rotating rod 35 drives the stirring blades 37 to rotate, and the petroleum coke is broken up by the stirring blades 37 before flowing to the bottom of the monitoring device 15, thereby improving the dispersion of the petroleum coke during the monitoring process, allowing the petroleum coke particles to maintain a stable flow state when being transported to the monitoring area, reducing the accumulation and mutual interference of the petroleum coke particles, and further improving the accuracy of particle size monitoring.

[0033] A floating mechanism 4 is provided in the monitoring box 1 above the air guide box 21, which is used to drive the petroleum coke to float up and down during the process of suspended fluidized transportation. The floating mechanism 4 includes a shielding plate 41 slidably connected to the inner wall of the exhaust groove 22 along the length direction of the exhaust groove 22, and each of the shielding plates 41 is provided with a plurality of exhaust holes 42 distributed in a linear array, and the plurality of shielding plates 41 are staggered. The upper end of the air guide box 21 is rotatably connected with a plurality of threaded sleeves 43, and the number of the threaded sleeves 43 is half of the number of the shielding plates 41, and the plurality of threaded sleeves 43 are connected to the upper end of the air guide box 21. The threaded sleeves 43 are equidistantly distributed between the two staggered baffle plates 41, the threaded sleeves 43 are internally threadedly connected with a threaded rod 44, a second gear ring 45 is fixedly connected to the circumferential side wall of each threaded sleeve 43, and racks 46 are fixedly connected to the baffle plates 41 located on both sides of the threaded sleeve 43, and the two racks 46 are respectively meshed with both sides of the second gear ring 45, a lifting rod 47 is linearly slidably connected to the position above the air guide box 21 in the monitoring box 1, and the threaded rod 44 is fixedly connected to the lower end of the lifting rod 47.

[0034] Specifically, although there are differences in the particle size of petroleum coke, during the process of the fluidized drying mechanism 2 suspending and fluidizing the petroleum coke and the floating mechanism 4 driving the petroleum coke to float up and down, the petroleum coke particles with the smallest particle size will not float up to the contact monitoring device 15, and the petroleum coke particles with the largest particle size will not sink and fall into the air guide box 21, thereby ensuring that the coverage range of the petroleum coke movement is initially between the monitoring device 15 and the air guide box 21.

[0035] Specifically, the friction coefficient between the threaded rod 44 and the threaded sleeve 43 is smaller than the tangent value of the thread helix angle, so that the threaded rod 44 and the threaded sleeve 43 are in a non-self-locking state, that is, the displacement of the threaded rod 44 can drive the threaded sleeve 43 to rotate.

[0036] Specifically, a limiting groove 5 is provided on the partition 11, and one end of the lifting rod 47 passes through the limiting groove 5 and extends to the inside of the transmission chamber 12. The positions above and below the limiting groove 5 in the partition 11 are sealed and slidably connected with sealing blocks 51, and the sealing blocks 51 are elastically connected to the inside of the partition 11 through a first spring. During the reciprocating vertical displacement of the lifting rod 47, no matter whether the lifting rod 47 is in an ascending state or a descending state, the sealing blocks 51 above and below the lifting rod 47 can be tightly attached to the lifting rod 47 under the action of the first spring elastic force, thereby ensuring that the petroleum coke will not overflow from the limiting groove 5 position into the transmission chamber 12, thereby ensuring the normal operation of the subsequent transmission assembly 39.

[0037] It should be noted that the present invention, by setting a floating mechanism 4, can drive the threaded rod 44 to perform reciprocating vertical displacement through the reciprocating vertical displacement of the lifting rod 47 during the process of suspending and fluidizing the petroleum coke. Since the threaded rod 44 and the threaded sleeve 43 are in a non-self-locking state, the vertical displacement of the threaded rod 44 will drive the threaded sleeve 43 to rotate, thereby driving the second gear ring 45 to rotate reciprocatingly in opposite directions, and further drive the baffle plates 41 on both sides to reciprocate through the rack 46 to move towards and away from each other. The amount of air discharged from the exhaust hole 42 on the baffle plate 41 is lower than the amount of air discharged from other positions of the exhaust groove 22. This difference in air volume will cause the petroleum coke particles to float up and down during the process of suspending and fluidizing, thereby further improving the dispersion of the petroleum coke.

[0038] A transmission assembly 39 is provided in the monitoring box 1 above the air guide box 21 and in the transmission chamber 12, which is used to drive the floating mechanism 4 to work through the transmission assembly 39 while the driving assembly 38 drives the material shaving mechanism 3 to work. The transmission assembly 39 includes a connecting rod 391 fixedly connected to the upper end of the lifting rod 47, and the connecting rod 391 extends through the monitoring box 1 and is fixedly connected to a transmission plate 392. A second spring 393 is provided between the transmission plate 392 and the upper end of the monitoring box 1. A transmission rod 394 is rotatably connected to the L-shaped plate 32 through a mounting block. A bevel gear set 395 is provided between the transmission rod 394 and the output end of the first motor 381. A cam 396 is fixedly connected to the end of the transmission rod 394 away from the bevel gear set 395, and the cam 396 periodically contacts and pushes the transmission plate 392 to move downward.

[0039] In addition, the present invention sets a driving component 38 and a transmission component 39. When in use, the first motor 381 can not only drive the material leveling mechanism 3 to work through the gear 382 and the first gear ring 383, but also drive the lifting rod 47 to reciprocate vertically through the bevel gear set 395, the transmission rod 394, the cam 396 and the transmission plate 392. While the driving component 38 drives the material leveling mechanism 3 to work, it can also drive the lifting rod 47 to reciprocate downward through the transmission component 39, and reciprocate upward and reset under the elastic force of the second spring 393, thereby driving the floating mechanism 4 to work, without setting an additional driving source, saving processing costs.

[0040] The present invention can be explained by the following operation mode: The petroleum coke is transported to the monitoring box 1 through the delivery pipe 14, and then the high-pressure gas is transported to the air guide box 21 through the air compressor 23, and further discharged through multiple exhaust slots 22, and the petroleum coke particles are suspended and fluidized by the air flow. Finally, the particle size of the petroleum coke in the suspended and fluidized state is monitored by the monitoring device 15. After the monitoring is completed, the petroleum coke falls on the inclined guide plate and further slides into the combustion tank for combustion and use. When the monitoring device 15 monitors that the particles of the petroleum coke do not meet the regulations, the alarm device set at the upper end of the monitoring box 1 is activated, and the staff promptly stops the machine for detection, so as to realize the continuous monitoring and use of the petroleum coke; During the monitoring process, one of the heating rods 24 is driven to rotate by the second motor 25, and multiple heating rods 24 are driven to rotate synchronously by chain transmission to uniformly heat the high-pressure gas in the air guide box 21; During the monitoring process, the first motor 381 is turned on, and the rotating sleeve 31 is driven to rotate relative to the fixed rod 33 through the gear 382 and the first gear ring 383, so that the rotating rod 35 on the rotating sleeve 31 performs a circular motion along the fixed rod 33, and in this process, the second bevel gear 36 is driven to rotate through the fixed first bevel gear 34, so that the rotating rod 35 drives the stirring blade 37 to rotate, and the petroleum coke is dispersed by the stirring blade 37 before flowing to the bottom of the monitoring device 15; During the monitoring process, the first motor 381 will also drive the lifting rod 47 to perform reciprocating vertical displacement through the bevel gear set 395, the transmission rod 394, the cam 396 and the transmission plate 392, and drive the threaded rod 44 to perform reciprocating vertical displacement, thereby driving the second gear ring 45 to rotate reciprocatingly in opposite directions, and further drive the baffle plates 41 on both sides to reciprocately move closer to and away from each other through the rack 46, so that the petroleum coke particles float up and down during the suspension and fluidization process.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
