Description

Technical Field

[0001] This invention relates to the field of petrochemical technology, and in particular to an arch-breaking structure for a dehydration chamber and a dehydration chamber itself. Background Technology

[0002] A petroleum coke dehydration silo is a device used for dehydrating petroleum coke. It primarily functions to settle and naturally dehydrate high-moisture-content petroleum coke, reducing its moisture content to the required level for subsequent transportation, storage, and sale. The working principle of the petroleum coke dehydration silo is based on the physical processes of gravity settling and filtration. After the high-moisture-content petroleum coke is fed into the silo, it remains stationary. Solid-liquid separation is achieved through the filtration structure within the silo, removing most of the moisture. The filtered water is discharged into a collection tank. After sufficient settling and dehydration time, the petroleum coke within the silo forms a moist but loosely flowing solid. A valve is installed at the discharge port at the bottom of the silo. Once dehydration is complete, the dehydrated petroleum coke is discharged from the silo by opening the valve.

[0003] During the dehydration process, petroleum coke forms a densely packed area in the lower part of the silo, a phenomenon known as arching. Once formed, this arch often doesn't disintegrate on its own and tends to become increasingly compacted, leading to blockages at the discharge port and preventing the petroleum coke from being discharged. Currently, the common practice for unloading petroleum coke is to manually break the arch by striking the bottom of the silo with tools. This external vibration forces the arch to break and disintegrate, allowing the petroleum coke to be discharged. However, manually breaking the arch by striking the silo is time-consuming, labor-intensive, and can easily damage the dehydration silo.

[0004] With technological advancements, existing technologies incorporate loosening structures within the dehydration chamber to loosen the petroleum coke inside, thereby breaking up arches. For example, CN209662731U discloses a dehydration chamber with a loosening mechanism at its center. This mechanism prevents the petroleum coke from arching, facilitating its unloading.

[0005] However, the loosening mechanism in the prior art is installed on the top of the chamber and is a top-drive structure. The loosening shaft of the loosening mechanism extends from the top of the chamber into the chamber and extends to the bottom of the chamber. The overall structure of the loosening mechanism is large, costly, difficult to install, and not conducive to subsequent maintenance. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0023] This invention provides an arch-breaking structure for a dehydration chamber, comprising a chamber body and an arch-breaking mechanism. The chamber body has a receiving space. The chamber body includes an upper chamber and a lower chamber located at the bottom of the upper chamber. The upper chamber has a feed inlet communicating with the receiving space, and the bottom of the lower chamber has a discharge outlet communicating with the receiving space. The lower chamber wall also has an arch-breaking opening communicating with the receiving space. The arch-breaking mechanism includes a linear drive unit and an arch-breaking device. The linear drive unit is located on the outer side of the lower chamber wall. The arch-breaking device is connected to the moving end of the linear drive unit, and extends from the arch-breaking opening into the receiving space, facing the discharge outlet. The arch-breaking structure of the dehydration chamber is provided with the linear drive unit on the lower chamber body. The operation of the linear drive unit drives the arch-breaking device to move back and forth in a linear motion within the lower chamber body, thereby loosening the petroleum coke in the lower chamber body and breaking the arch. The arch-breaking mechanism is miniaturized, which can reduce costs and installation difficulty, and also facilitates subsequent maintenance of the arch-breaking structure.

[0024] Please refer to the following: Figures 1 to 5In one embodiment, an arch-breaking structure 100 for a dehydration chamber is provided, primarily used in petroleum coke dehydration chambers to break up arches in the petroleum coke. The arch-breaking structure 100 addresses the problems of existing petroleum coke dehydration chamber arch-breaking structures being large in size, requiring significant space, resulting in high costs and difficulties in installation and maintenance. The arch-breaking structure 100 installs the arch-breaking mechanism at the lower part of the chamber body. An arch-breaking opening is directly created in the lower chamber wall, through which the mechanism extends directly into the chamber body. The arch-breaking mechanism directly breaks up the arch at the discharge port of the dehydration chamber, achieving excellent arch-breaking results while miniaturizing the structure, thereby reducing costs and simplifying installation and maintenance.

[0025] The arch-breaking structure 100 of the dehydration chamber includes a chamber body 10 and an arch-breaking mechanism 20. The chamber body 10 has a receiving space 11, through which petroleum coke can be contained. The chamber body 10 includes an upper chamber body 12 and a lower chamber body 13 located at the bottom of the upper chamber body 12. The upper chamber body 12 has a feed inlet communicating with the receiving space 11, and the bottom of the lower chamber body 13 has a discharge outlet 131 communicating with the receiving space 11. Furthermore, the chamber wall of the lower chamber body 13 also has an arch-breaking opening 132 communicating with the receiving space 11. When the dehydration chamber is in use, petroleum coke can be fed into the receiving space 11 through the feed inlet, and the dehydrated petroleum coke can be discharged through the discharge outlet 131.

[0026] The arch-breaking mechanism 20 includes a linear drive unit 21 and an arch-breaker 22. The linear drive unit 21 is a unit capable of linear motion, driving the arch-breaker 22 to reciprocate linearly. The linear drive unit 21 is located on the outer side of the lower silo 13 wall. The arch-breaker 22 is connected to the moving end of the linear drive unit 21 and extends from the arch-breaking opening 132 into the receiving space 11, facing the discharge port 131. During the arch-breaking operation, the moving end of the linear drive unit 21 reciprocates, driving the arch-breaker 22 to reciprocate within the receiving space 11. The reciprocating impact of the arch-breaker 22 within the receiving space 11 loosens the petroleum coke near the discharge port 131, causing the arch to break apart.

[0027] Understandably, the existing arch-breaking structure extends from the top of the silo to the bottom, requiring a large space, which not only increases costs but also makes installation and maintenance difficult.

[0028] In this embodiment, the arch-breaking structure 100 of the dehydration chamber directly opens the arch-breaking opening 132 on the chamber wall of the lower chamber 13, allowing the arch-breaking mechanism 20 to directly extend into the lower chamber 13 through the arch-breaking opening 132. Since the arch-breaking opening 132 is located in the bottom area of ​​the chamber 10, a smaller arch-breaking mechanism 20 can be used to achieve arch breaking, eliminating the need for a large arch-breaking mechanism, thereby reducing costs and making installation more convenient. It also facilitates the disassembly and replacement of the arch-breaking mechanism 20 when maintenance is required. The arch-breaking device 22 is directly facing the discharge port 131, allowing for more targeted arch-breaking operations in this area, ensuring that petroleum coke can be smoothly discharged from the discharge port 131. After the petroleum coke located in the discharge port 131 area is discharged, the petroleum coke located in the upper area of ​​the receiving space 11 will also fall due to gravity, thereby ensuring the overall discharge effect. Even if the miniaturized arch-breaking mechanism 20 is used, it will not affect the final overall discharge effect.

[0029] Specifically, in one embodiment, the upper compartment 12 is a cylindrical compartment structure, and the lower compartment 13 is a conical compartment structure.

[0030] Preferably, in one embodiment, a hollow sleeve 14 is provided at the arch-breaking opening 132. The hollow sleeve 14 is inclinedly disposed on the wall of the lower compartment 13, and extends from inside the lower compartment 13 to the outside of the lower compartment 13. The hollow sleeve 14 is inclined, for example, as... Figure 3 As shown, the hollow sleeve 14 is inclined to the upper right, with its lowest point located in the receiving space 11 and its highest point located outside the lower hopper 13. This prevents petroleum coke in the receiving space 11 from flowing out through the hollow sleeve 14. The arch-breaking mechanism 20 is inclined, and the arch-breaking device 22 extends into the receiving space 11 through the hollow sleeve 14. In this embodiment, the hollow sleeve 14 better prevents petroleum coke in the receiving space 11 from flowing out through the arch-breaking opening 132, and also facilitates the installation of the arch-breaking mechanism 20 to some extent. By inclining the arch-breaking mechanism 20, the linear drive unit 21 can drive the arch-breaking device 22 to reciprocate downwards towards the discharge port 131 during operation, which is more conducive to the unloading of material from the discharge port 131.

[0031] Preferably, in one embodiment, a hollow mounting base 141 is provided on the end of the hollow sleeve 14 located in the receiving space 11, and a baffle ring 142 is provided on the inner side of the hollow mounting base 141, the baffle ring 142 contacting the circumferential surface of the arch breaker 22. The baffle ring 142 can scrape off petroleum coke adhering to the arch breaker 22, preventing petroleum coke from being carried into the hollow sleeve 14 during the reciprocating movement of the arch breaker 22. Furthermore, using the hollow mounting base 141 to install the baffle ring 142 also reduces the installation difficulty of the baffle ring 142.

[0032] To avoid interference between the hollow sleeve 14 and the arch breaker 22, preferably, in one embodiment, the diameter of the hollow sleeve 14 should be larger than the diameter of the arch breaker 22.

[0033] Preferably, in one embodiment, a first mounting base 15 and a second mounting base 16 are provided on the outer side of the lower compartment 13, with the first mounting base 15 located above the second mounting base 16. The arrangement of the first mounting base 15 and the second mounting base 16 facilitates a stable and reliable connection between the linear drive unit 21 and the lower compartment 13. The upper end of the linear drive unit 21 is detachably mounted on the first mounting base 15, and the lower end of the linear drive unit 21 is sealed and mounted on the second mounting base 16. The upper end of the hollow sleeve 14 is connected to the second mounting base 16. Specifically, "the lower end of the linear drive unit 21 is sealed and mounted on the second mounting base 16" means that the lower end of the linear drive unit 21 is mounted on the second mounting base 16, and a sealing structure is provided between the linear drive unit 21 and the second mounting base 16. By providing a sealing structure between the linear drive unit 21 and the second mounting base 16, external substances can be prevented from entering the hollow sleeve 14, and consequently, external substances can be prevented from entering the lower compartment 13 through the hollow sleeve 14. Furthermore, the linear drive unit 21 is installed in a detachable manner, which facilitates subsequent maintenance and replacement of the linear drive unit 21.

[0034] Specifically, in one embodiment, the upper end of the linear drive unit 21 is provided with a mounting plate 211, and the upper end of the linear drive unit 21 is detachably connected to the first mounting base 15 through the mounting plate 211. More specifically, in one embodiment, the mounting plate 211 and the first mounting base 15 can be detachably connected by bolts and nuts, thereby facilitating the installation and removal of the linear drive unit 21.

[0035] Specifically, in one embodiment, a sealing connection seat 17 may be provided at the second mounting seat 16. The sealing connection seat 17 is detachably connected to the second mounting seat 16 (specifically, it can also be detachably connected by bolts and nuts). The sealing connection seat 17 includes a first seat body 171, a second seat body 172, and a sealing ring 173 disposed between the first seat body 171 and the second seat body 172. The linear drive unit 21 passes through the first seat body 171 and the second seat body 172. The sealing ring 173 abuts against the lower end of the linear drive unit 21, thereby achieving a seal on the lower end of the linear drive unit 21.

[0036] Preferably, in one embodiment, the arch breaker 22 is rotatably mounted on the linear drive unit 21. That is, the arch breaker 22 can rotate, so that when the linear drive unit 21 drives the arch breaker 22 to move, the arch breaker 22 can achieve both linear movement and passive rotation. In other words, in this embodiment, when the arch breaker 22 impacts the petroleum coke, it does so in a linear and rotational manner, impacting the petroleum coke with a composite force (kinetic impact + shear force + torsional force). The impact energy is more effectively dispersed and absorbed at the contact surface and inside the petroleum coke, resulting in more uniform material crushing and effective disintegration of clumps. This is better suited to petroleum coke, which is sticky, wet, and prone to caking. Furthermore, the rotational motion of the arch breaker 22 has a self-cleaning effect, better removing adhering materials. The specific implementation of the arch breaker 22 being rotatably mounted on the linear drive unit 21 can be that the moving end (piston rod) of the linear drive unit 21 itself can rotate, or it can be that the arch breaker 22 and the moving end of the linear drive unit 21 are rotatably connected.

[0037] Understandably, existing arch-breaking mechanisms require two power sources: one for linear movement and one for rotation. However, by making the arch-breaking device 22 rotatable, it can passively rotate under the reaction force of the petroleum coke during linear movement, eliminating the need for a separate power source for rotation. This simplifies the overall structure and further reduces costs.

[0038] Preferably, in one embodiment, the arch-breaking device 22 includes an arch-breaking main shaft 221 and an arch-breaking head 222. The arch-breaking main shaft 221 is disposed on the moving end of the linear drive unit 21, and the arch-breaking head 222 is disposed at the end of the arch-breaking main shaft 221. Multiple arch-breaking teeth 2221 are provided on the surface of the arch-breaking head 222. By providing the arch-breaking teeth 2221 on the surface of the arch-breaking head 222, wear resistance can be enhanced, increasing the service life of the arch-breaking device 22. Furthermore, the arch-breaking effect of the arch-breaking device 22 can also be improved. Specifically, when the linear drive unit 21 drives the arch-breaking device 22 to perform reciprocating linear motion, when the arch-breaking head 222 with the arch-breaking teeth 2221 impacts the material, the edges and corners of the teeth will generate a strong shearing action with the material, concentrating the impact force on a few very small points. This generates greater pressure, allowing the tooth tips to easily penetrate into the hardened material, thereby improving the arch-breaking effect on petroleum coke.

[0039] Specifically, in one embodiment, the arch-breaking tooth 2221 may be an alloy tooth.

[0040] Preferably, in one embodiment, the arch-breaking main shaft 221 is rotatably connected to the moving end of the linear drive unit 21 via a bearing 23, and the arch-breaking teeth 2221 on the surface of the arch-breaking head 222 are spirally distributed. That is, in this embodiment, the rotatable configuration of the arch-breaking device 22 is specifically achieved by connecting the arch-breaking main shaft 221 to the linear drive unit 21 via the bearing 23, thereby enabling the arch-breaking device 22 to rotate relative to the linear drive unit 21. Furthermore, the plurality of arch-breaking teeth 2221 on the arch-breaking head 222 are spirally distributed, meaning that the plurality of arch-breaking teeth 2221 are staggered in the axial and circumferential directions and distributed in a spiral structure along one direction. This allows the arch-breaking device 22 to rotate as it moves forward, guided by the reaction force from the spirally distributed arch-breaking teeth 2221, thus better ensuring that the arch-breaking device 22 rotates passively.

[0041] Specifically, in one embodiment, the bearing 23 is a spherical bearing.

[0042] Preferably, in one embodiment, the arch-breaking head 222 has a tapering structure from the direction near the arch-breaking main axis 221 to the direction away from the arch-breaking main axis 221. For example, as Figure 3 As shown, the arch-breaking head 222 is a tapered structure with a gradually decreasing size from the upper right to the lower left, which makes it more advantageous for the arch-breaking device 22 to impact and break the petroleum coke.

[0043] Preferably, in one embodiment, the linear drive unit 21 is an electro-hydraulic cylinder. By using an electro-hydraulic cylinder as a power source, the arch-breaking mechanism 20 has a large thrust, as well as good control accuracy and stability.

[0044] Preferably, in one embodiment, multiple arch-breaking mechanisms 20 are provided, and the multiple arch-breaking mechanisms 20 are distributed sequentially and at intervals along the circumference of the lower silo 13. Each arch-breaking mechanism 20 is provided with an arch-breaking opening 22, that is, multiple arch-breaking openings 22 are also provided on the wall of the lower silo 13, and one arch-breaking opening 22 corresponds to one arch-breaking mechanism 20, so that the arch-breaking device 22 of each arch-breaking mechanism 20 can extend into the lower silo 13 to perform arch-breaking operations. By providing multiple arch-breaking mechanisms 20 in the circumferential direction, the arch-breaking area can be increased, which can prevent petroleum coke from accumulating and arching on one side of the lower silo 13, and can further increase the arch-breaking effect and efficiency.

[0045] Understandably, to avoid interference between the various arch-breaking mechanisms 20 during operation, the arch-breaking mechanisms 20 can operate sequentially. For example, when one arch-breaking mechanism 20 retracts, another arch-breaking mechanism 20 can extend. Furthermore, the maximum stroke points of the various arch-breaking mechanisms 20 may not be at the same point. The maximum stroke points of the various arch-breaking mechanisms 20 can be sequentially distributed in a ring-shaped area above the discharge port 131. That is, the maximum stroke points of the arch-breaking mechanisms 20 are not on the central axis of the hopper 10, but rather offset from the central axis, so that the maximum stroke points of the various arch-breaking mechanisms 20 are distributed in a ring-shaped area, thereby avoiding interference.

[0046] In one embodiment, a dehydration chamber 1000 is also provided, comprising an arch-breaking structure 100, a discharge valve 200, a filter mechanism 300, and a drainage system 400. The discharge valve 200 is located at the discharge port 131, and the opening and closing of the discharge port 131 is controlled by opening and closing the discharge valve 200. The filter mechanism 300 is located on the chamber body 10, and is mainly used to filter moisture in the petroleum coke. The drainage system 400 is connected to the filter mechanism 300, and the moisture filtered by the filter mechanism 300 is collected centrally through the drainage system 400.

[0047] Specifically, in one embodiment, the filter mechanism 300 includes an upper filter group 310, a middle filter group 320, and a lower filter group 330. The upper filter group 310 and the middle filter group 320 are disposed on the upper chamber 12, and the lower filter group 330 is disposed on the lower chamber 13. The arrangement of the three filter groups can further improve the filtration effect. More specifically, in one embodiment, the filters in the lower filter group 330 are distributed sequentially at intervals along the circumference of the lower chamber 13. To avoid interference between the anti-arching mechanism 20 and the filters of the lower filter group 330, the anti-arching mechanism 20 and the filters of the lower filter group 330 are staggered circumferentially.

[0048] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
