Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a dehydration chamber. 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 a filter screen 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 long-term use of the dehydration chamber, material can easily accumulate in the filter channels of the filter screen, causing the filter screen to become clogged and affecting its filtration capacity. Therefore, the filter screen needs to be cleaned frequently to restore its filtration capacity.

[0004] In existing technologies, a rinsing mechanism is installed on the inner side of the filter screen. When the filter screen needs to be cleaned, the rinsing mechanism sprays high-pressure water from the inside of the filter screen. The high-pressure water impacts the accumulated material in the filter channel from the inside out, causing the accumulated material to fall out of the filter channel, thereby cleaning the filter screen and restoring its filtration capacity. For example, CN109351018A discloses a filtration device and dewatering chamber, which has a rinsing mechanism 43 installed on the inner side of the filter screen 42. When material clogs the filtration device, the rinsing mechanism 43 is activated to clean the filter screen 42.

[0005] However, cleaning the filter screen with high-pressure water requires pressurization equipment to increase the water pressure, which is costly. In addition, the high-pressure water will also impact the filter screen during the cleaning process, which can easily damage the filter screen and affect its stability. Utility Model Content

This invention provides a dehydration chamber with a vertically movable cleaning component on the filter screen. The cleaning component has cleaning blades that extend into the filter channel. When the filter screen becomes clogged, the cleaning component moves vertically, causing the cleaning blades to move up and down within the filter channel. During this movement, the cleaning blades scrape away the accumulated material. The overall structure is simple and low-cost. Furthermore, the cleaning process avoids impacting the filter screen, thus minimizing damage and ensuring greater filter stability.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that when a component is referred to as "mounted on", "fixed on", or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to the other component.

Therefore, they have no substantial technical significance.

[0023] This utility model provides a dehydration chamber, which includes a chamber body, a filter screen, a drainage system, and a cleaning component. The chamber body has a receiving space, and the chamber body also has an inlet and an outlet respectively communicating with the receiving space. A discharge valve is provided at the outlet. The filter screen is disposed within the chamber body and has a filtration channel that extends continuously along the height direction. The drainage system is connected to the filter screen. The cleaning component is disposed on the filter screen and includes a cleaning component body and a cleaning plate disposed on the cleaning component body. The cleaning plate is located in the filtration channel. The cleaning component is movable relative to the filter screen along the height direction, so that the cleaning plate moves along the filtration channel. The dehydration chamber is equipped with the cleaning component within the filter screen. When the filter screen becomes clogged, simply moving the cleaning component up and down along the filter screen allows the accumulated material in the filtration channel to be scraped away by the cleaning blades, thus cleaning the filter screen and restoring its filtration capacity. The overall structure is simple and low-cost. Furthermore, the cleaning process does not cause impact to the filter screen, thus reducing the risk of damage and better ensuring the stability of the filter screen.

[0024] Please refer to the following: Figures 1 to 7 In one embodiment, a dehydration chamber 100 is provided, which is a dehydration chamber used for petroleum coke. The dehydration chamber 100 is mainly used to solve the problems of high cost and easy damage to the filter screen when cleaning the filter screen in the existing dehydration chamber.

[0025] The dehydration chamber 100 includes a chamber body 10, a filter screen 20, a drainage system 30, and a cleaning component 40. The chamber body 10 has a receiving space 11 to accommodate petroleum coke. The chamber body 10 also has an inlet and an outlet 12 respectively connected to the receiving space 11. A discharge valve 13 is installed at the outlet 12. When the dehydration chamber is in use, petroleum coke is fed into the receiving space 11 through the inlet. After dehydration, the dehydrated petroleum coke is discharged from the outlet 12 by opening the discharge valve 13.

[0026] The filter screen 20 is disposed within the chamber 10. The filter screen 20 contains filtration channels that extend continuously along the height direction. These filtration channels are used to filter petroleum coke and water. When petroleum coke is injected into the containing space 11, the filter screen 20 blocks the petroleum coke from entering, while the water contained in the petroleum coke flows into the filter screen 20 through the filtration channels, thus achieving filtration of the petroleum coke. The phrase "the filtration channel extends continuously along the height direction" means that the filtration channel is a continuous channel along the height direction without any obstruction structures. Specifically, the filtration channel can be a vertically arranged continuous channel, an inclined continuous channel, or even a spiral continuous channel, as long as the channel is continuous along the height direction.

[0027] The drainage system 30 is connected to the filter screen 20. Water filtered out of the chamber 10 by the filter screen 20 is discharged into the drainage system 30 and then discharged to the outside through the drainage system 30.

[0028] The cleaning component 40 is disposed on the filter screen 20. The cleaning component 40 includes a cleaning component body 41 and a cleaning disc 42 disposed on the cleaning component body 41, the cleaning disc 42 being located in the filter channel. The cleaning component 40 is movable relative to the filter screen 20 along the height direction, so that the cleaning disc 42 moves along the filter channel. That is, the cleaning component 40 is movably disposed on the filter screen 20. The cleaning component 40 can move relative to the filter screen 20 along the height direction under the drive of an external power source. Since the filter channel extends continuously along the height direction, the cleaning disc 42 also moves along the filter channel when the cleaning component 40 moves.

[0029] When material accumulates in the filter channel, the cleaning member 40 moves up and down relative to the filter screen 20, thereby enabling the cleaning plate 42 to scrape away the material accumulated in the filter channel, thus cleaning the filter screen 20 and preventing the filter channel from becoming clogged.

[0030] Understandably, the existing technology involves setting up a flushing mechanism on the inside of the filter screen. This mechanism sprays high-pressure water, which, through radial impact, flushes the accumulated material back into the chamber, thus cleaning the material accumulated in the filtration channel. However, this method has the following problems: First, it requires pressurization equipment to increase the water pressure, resulting in high costs; second, the high-pressure water impacts the filter screen, easily damaging it and affecting the filtration stability.

[0031] The dehydration chamber 100 provided in this embodiment uses a movable cleaning component 40 on the filter screen 20. The movement of the cleaning component 40 scrapes away accumulated material axially. The overall structure is simple, eliminating the need for additional pressurization equipment, thus reducing costs. Furthermore, the cleaning process minimizes impact on the filter screen 20, reducing the risk of damage. Moreover, using the cleaning component 40 to clean the filter screen 20 eliminates the need for a flushing mechanism and corresponding piping within the filter screen 20, further reducing costs and simplifying installation. Additionally, the elimination of the flushing mechanism and piping within the filter screen 20 allows for greater flexibility in structural design, ultimately improving filtration efficiency.

[0032] Specifically, in one embodiment, the filter screen 20 includes a mounting base 21, a filter screen body 22, and a drain connector 23 arranged sequentially from top to bottom. The mounting base 21 and the drain connector 23 are respectively fixed on the chamber 10, and the drain connector 23 is connected to the drainage system 30. The filtration channel is disposed on the filter screen body 22, and the cleaning component 40 is disposed on the filter screen body 22. The water filtered by the filter screen body 22 flows into the drain connector 23 and then is discharged into the drainage system 30 through the drain connector 23.

[0033] Specifically, in one embodiment, the filter body 22 is composed of multiple filter strips, which are arranged sequentially at intervals, forming a filtration channel between adjacent filter strips. The top and bottom of each filter strip are fixed to the mounting base 21 and the drain connector 23, respectively, thereby forming a stable filter 20. In one embodiment, the cross-section of the filter strip can be triangular or trapezoidal, etc., as detailed in CN109351018A, and will not be elaborated further here.

[0034] Specifically, in one embodiment, the filter strips are arranged sequentially at intervals along the circumference to form a cylindrical filter body 22, thereby improving filtration efficiency.

[0035] Preferably, in one embodiment, the cleaning component 40 is a floating component, which refers to a component capable of floating on the surface of a liquid. When cleaning liquid is injected into the receiving space 11, the cleaning component 40 can move upward under the action of buoyancy. That is, in this embodiment, when the filter screen 20 needs to be cleaned, cleaning liquid is injected into the receiving space 11. As the cleaning liquid is gradually injected, the liquid level gradually rises, thereby driving the cleaning component 40 to move upward. After cleaning is completed, the cleaning liquid can be discharged by opening the discharge valve 13. As the cleaning liquid is discharged, the cleaning component 40 can automatically descend under the action of gravity. Specifically, during cleaning, as the cleaning liquid is injected, the cleaning component 40 can eventually float to the top of the filter screen body 22 (e.g., ...). Figure 2 (as shown in area T), and when the cleaning liquid is discharged, the cleaning component 40 can descend to the bottom of the filter screen body 22 under the action of gravity (as shown in area T). Figure 2 (See area D shown). This structural design eliminates the need for an additional drive mechanism to move the cleaning component 40, simplifying the internal structure of the chamber 10 and reducing costs. The specific material and shape of the cleaning component 40 can be selected based on the cleaning liquid used; it simply needs to float after the cleaning liquid is injected. Specifically, in one embodiment, to reduce costs and avoid corrosion of the chamber 10, water is used as the cleaning liquid, and the cleaning component 40 is a floating component capable of buoyancy.

[0036] Specifically, in one embodiment, the cleaning component body 41 is a hollow structure. By making the cleaning component body 41 a hollow structure, the mass of the cleaning component body 41 can be reduced. Furthermore, it can prevent the cleaning component body 41 from obstructing the normal flow of water in the filter screen 20, and also prevent material from accumulating on the cleaning component body 41 when water flows through it, thus avoiding affecting the upward movement of the cleaning component body 41. More specifically, in one embodiment, the cleaning component body 41 is a hollow annular structure.

[0037] Preferably, in one embodiment, the cleaning plate 42 is disposed on the outside of the cleaning component body 41, and the cleaning component body 41 is located on the inside of the filter strip of the filter screen 20. That is, the cleaning component body 41 is disposed inside the filter screen 20, rather than being sleeved on the outside. This structural design can better prevent material from accumulating on the cleaning component body 41, thus avoiding affecting the normal floating of the cleaning component 40.

[0038] Preferably, in one embodiment, the cleaning plate 42 extends from inside the filter screen 20 to outside the filter screen 20 along the radial direction. That is, in this embodiment, the cleaning plate 42 passes radially through the filter channel, thereby better ensuring the cleaning effect and ensuring that the cleaning plate 42 can open the corresponding filter channel after passing through.

[0039] Considering the influence of factors such as processing errors and assembly errors, preferably, in one embodiment, the width of the cleaning piece 42 is smaller than the minimum width of the filter channel, thereby reducing the installation difficulty of the cleaning piece 40 and better ensuring that the cleaning piece 42 can pass through the filter channel.

[0040] Specifically, in one embodiment, the total weight of the cleaning component 40 is 0.6 kg, and the maximum buoyancy is 140 N.

[0041] Preferably, in one embodiment, a plurality of filter channels are sequentially spaced along the circumference of the filter screen 20. A plurality of cleaning plates 42 are sequentially spaced along the circumference of the cleaning component body 41. The number of cleaning plates 42 is less than the number of filter channels, and each cleaning plate 42 corresponds to one filter channel. That is, in a filter screen 20, not every filter channel is provided with a cleaning plate 42, but only a portion of them are provided with cleaning plates 42. The reason for this design is that, typically, to ensure filtration accuracy, filtration effect, and efficiency, the width of the filter channels is relatively narrow, and the number of filter channels on a filter screen 20 is also relatively large. It is difficult to process the same number of cleaning plates 42 on the cleaning component 40 as the number of filter channels. Even after processing, due to factors such as processing errors, it is easy for the cleaning component 40 to be difficult to align with the filter screen 20, which may result in the cleaning component 40 being unable to be installed. Therefore, in this embodiment, the number of cleaning plates 42 is reduced. Each cleaning plate 42 only needs to be inserted into one filter channel. For example, one cleaning plate 42 can be placed every five (or other) filter channels. This achieves cleaning of the filter screen 20 while reducing the processing and installation difficulty of the cleaning component 40. Furthermore, the reduced number of cleaning plates 42 also reduces the resistance encountered when the cleaning component 40 floats, allowing it to float more smoothly and preventing it from getting stuck.

[0042] Preferably, in one embodiment, a first filter group 201, a second filter group 202, and a third filter group 203 are sequentially arranged from top to bottom within the chamber 10. The first filter group 201 includes multiple filter screens 20, which are spaced apart sequentially along the circumference of the chamber 10, and each filter screen 20 is provided with a cleaning element 40. The second filter group 202 also includes multiple filter screens 20, which are spaced apart sequentially along the circumference of the chamber 10, and each filter screen 20 is provided with a cleaning element 40. The arrangement of these three filter groups further improves the dehydration efficiency of the dehydration chamber 100.

[0043] Preferably, in one embodiment, each filter screen 20 in the first filter screen group 201 is vertically arranged, and each filter screen 20 in the second filter screen group 202 is vertically arranged. By vertically arranging the filter screens 20, it is possible to better avoid obstruction when the cleaning component 40 floats or descends, and to prevent the cleaning component 40 from getting stuck.

[0044] More preferably, in one embodiment, the filter channels of the cleaning plates 42 in each of the filter screens 20 are vertically arranged. That is, in this embodiment, all the cleaning plates 42 are arranged in the vertically continuous elongated filter channels, rather than in inclined or spiral filter channels, thereby better preventing the cleaning plates 42 from being blocked when floating or descending, and preventing the cleaning components 40 from getting stuck. Specifically, in one embodiment, the filter channels on each of the filter screens 20 in the first filter screen group 201 are all vertically arranged, and the filter channels on each of the filter screens 20 in the second filter screen group 202 are all vertically arranged, thereby reducing the difficulty of installation.

[0045] Preferably, in one embodiment, the chamber 10 includes an upper chamber 14 and a lower chamber 15 located at the bottom of the upper chamber 14. The feed inlet is located on the upper chamber 14, and the discharge outlet 12 is located at the bottom of the lower chamber 15. The lower chamber 15 also has an arch-breaking opening 151 communicating with the receiving space 11 on its wall. The dewatering chamber 100 further includes an arch-breaking mechanism 50, which includes a linear drive unit 51 and an arch-breaking device 52. The linear drive unit 51 is a unit capable of linear motion drive, and the operation of the linear drive unit 51 can drive the arch-breaking device 52 to reciprocate linearly. The linear drive unit 51 is located on the outside of the lower chamber 15 wall, and the arch-breaking device 52 is connected to the moving end of the linear drive unit 51. The arch-breaking device 52 extends into the receiving space 11 from the arch-breaking opening 151 and is positioned towards the discharge outlet 12. During the arch-breaking operation, the moving end of the linear drive unit 51 reciprocates, thereby driving the arch-breaker 52 to reciprocate within the receiving space 11. Through the reciprocating impact of the arch-breaker 52 within the receiving space 11, the petroleum coke near the discharge port 12 in the receiving space 11 is loosened, causing the arch to break apart.

[0046] Understandably, 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. Therefore, arch-breaking operations are necessary during petroleum coke discharge. Current technology incorporates a loosening mechanism within the dehydration silo to loosen the petroleum coke and thus break the arch. However, this existing loosening mechanism extends from the top to the bottom of the silo, requiring significant space, increasing costs, and making the installation and maintenance of the arch-breaking structure difficult.

[0047] In this embodiment, the dehydration chamber 100 directly opens the arch-breaking opening 151 on the wall of the lower chamber 15, allowing the arch-breaking mechanism 50 to directly extend into the lower chamber 15 through the arch-breaking opening 151. Since the arch-breaking opening 151 is located in the bottom area of ​​the chamber 10, a smaller arch-breaking mechanism 50 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 disassembly and replacement of the arch-breaking mechanism 50 during maintenance. The arch-breaking device 52 is directly facing the discharge port 12, allowing for more targeted arch breaking operations in this area, ensuring that petroleum coke can be smoothly discharged from the discharge port 12. After the petroleum coke located in the discharge port 12 area is discharged, the petroleum coke located in the upper area of ​​the receiving space 11 will also fall due to gravity, ensuring the overall discharge effect. Even with a miniaturized arch-breaking mechanism 50, the final overall discharge effect will not be affected.

[0048] Specifically, in one embodiment, the upper compartment 14 is a cylindrical compartment structure, and the lower compartment 15 is a conical compartment structure.

[0049] Preferably, in one embodiment, a hollow sleeve 16 is provided at the arch-breaking opening 151. The hollow sleeve 16 is inclinedly disposed on the wall of the lower compartment 15, and tilts upward from inside the lower compartment 15 to outside the lower compartment 15. For example, Figure 5 As shown, the hollow sleeve 16 is inclined to the upper right, with its low point located in the receiving space 11 and its high point located outside the lower hopper 15. This prevents petroleum coke in the receiving space 11 from flowing out through the hollow sleeve 16. The arch-breaking mechanism 50 is inclined, and the arch-breaking device 52 extends into the receiving space 11 through the hollow sleeve 16. In this embodiment, the hollow sleeve 16 better prevents petroleum coke in the receiving space 11 from flowing out through the arch-breaking opening 151, and also facilitates the installation of the arch-breaking mechanism 50 to some extent. By inclining the arch-breaking mechanism 50, the linear drive unit 51 can drive the arch-breaking device 52 to reciprocate downwards towards the discharge port 12 during operation, which is more conducive to the unloading of material from the discharge port 12.

[0050] Preferably, in one embodiment, a hollow mounting base 161 is provided on the end of the hollow sleeve 16 located in the receiving space 11, and a baffle ring 162 is provided on the inner side of the hollow mounting base 161, the baffle ring 162 contacting the circumferential surface of the arch breaker 52. The baffle ring 162 can scrape off petroleum coke adhering to the arch breaker 52, preventing petroleum coke from being carried into the hollow sleeve 16 during the reciprocating movement of the arch breaker 52. Furthermore, using the hollow mounting base 161 to install the baffle ring 162 also reduces the installation difficulty of the baffle ring 162.

[0051] To avoid interference between the hollow sleeve 16 and the arch breaker 52, preferably, in one embodiment, the diameter of the hollow sleeve 16 should be larger than the diameter of the arch breaker 52.

[0052] Preferably, in one embodiment, a first mounting base 152 and a second mounting base 153 are provided on the outer side of the lower compartment 15, with the first mounting base 152 located above the second mounting base 153. The arrangement of the first mounting base 152 and the second mounting base 153 facilitates a stable and reliable connection between the linear drive unit 51 and the lower compartment 15. The upper end of the linear drive unit 51 is detachably mounted on the first mounting base 152, and the lower end of the linear drive unit 51 is sealed and mounted on the second mounting base 153. The upper end of the hollow sleeve 16 is connected to the second mounting base 153. Specifically, "the lower end of the linear drive unit 51 is sealed and mounted on the second mounting base 153" means that the lower end of the linear drive unit 51 is mounted on the second mounting base 153, and a sealing structure is provided between the linear drive unit 51 and the second mounting base 153. By providing a sealing structure between the linear drive unit 51 and the second mounting base 153, external substances can be prevented from entering the hollow sleeve 16, and consequently, external substances can be prevented from entering the lower compartment 15 through the hollow sleeve 16. Furthermore, the linear drive unit 51 is installed in a detachable manner, which facilitates subsequent maintenance and replacement of the linear drive unit 51.

[0053] Specifically, in one embodiment, the upper end of the linear drive unit 51 is provided with a mounting plate 511, and the upper end of the linear drive unit 51 is detachably connected to the first mounting base 152 through the mounting plate 511. More specifically, in one embodiment, the mounting plate 511 and the first mounting base 152 can be detachably connected by bolts and nuts, thereby facilitating the installation and removal of the linear drive unit 51.

[0054] Specifically, in one embodiment, a sealing connection seat 154 may be provided at the second mounting seat 153. The sealing connection seat 154 is detachably connected to the second mounting seat 153 (specifically, it can also be detachably connected by bolts and nuts). The sealing connection seat 154 includes a first seat body 1541, a second seat body 1542, and a sealing ring 1543 disposed between the first seat body 1541 and the second seat body 1542. The linear drive unit 51 passes through the first seat body 1541 and the second seat body 1542. The sealing ring 1543 abuts against the lower end of the linear drive unit 51, thereby achieving a seal on the lower end of the linear drive unit 51.

[0055] Preferably, in one embodiment, the arch breaker 52 is rotatably mounted on the linear drive unit 51. That is, the arch breaker 52 can rotate, so that when the linear drive unit 51 drives the arch breaker 52 to move, the arch breaker 52 can achieve both linear movement and passive rotation. In other words, in this embodiment, when the arch breaker 52 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 52 has a self-cleaning effect, better removing adhering materials. Specifically, the arch breaker 52 can be rotatably mounted on the linear drive unit 51. This can be achieved by the linear drive unit 51 itself having a rotatable moving end (piston rod), or by a rotatable connection between the arch breaker 52 and the moving end of the linear drive unit 51.

[0056] Understandably, existing loosening mechanisms require two power sources: one for linear movement and one for rotation. However, by making the arch breaker 52 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.

[0057] Preferably, in one embodiment, the arch-breaking device 52 includes an arch-breaking main shaft 521 and an arch-breaking head 522. The arch-breaking main shaft 521 is disposed on the moving end of the linear drive unit 51, and the arch-breaking head 522 is disposed at the end of the arch-breaking main shaft 521. Multiple arch-breaking teeth 5221 are provided on the surface of the arch-breaking head 522. Providing the arch-breaking teeth 5221 on the surface of the arch-breaking head 522 enhances wear resistance, increases the service life of the arch-breaking device 52, and also improves the arch-breaking effect of the arch-breaking device 52. Specifically, when the linear drive unit 51 drives the arch-breaking device 52 to perform reciprocating linear motion, when the arch-breaking head 522 with the arch-breaking teeth 5221 impacts the material, the edges and corners of the teeth generate a strong shearing action with the material, concentrating the impact force on a few very small points. This generates significant pressure, allowing the tooth tips to easily penetrate the hardened material, thereby improving the arch-breaking effect on petroleum coke.

[0058] Specifically, in one embodiment, the arch-breaking tooth 5221 may be an alloy tooth.

[0059] Preferably, in one embodiment, the arch-breaking main shaft 521 is rotatably connected to the moving end of the linear drive unit 51 via a bearing 523, and the arch-breaking teeth 5221 on the surface of the arch-breaking head 522 are spirally distributed. That is, in this embodiment, the rotatable configuration of the arch-breaking device 52 is specifically achieved by connecting the arch-breaking main shaft 521 to the linear drive unit 51 via the bearing 523, thereby enabling the arch-breaking device 52 to rotate relative to the linear drive unit 51. Furthermore, the plurality of arch-breaking teeth 5221 on the arch-breaking head 522 are spirally distributed, meaning that the plurality of arch-breaking teeth 5221 are staggered in the axial and circumferential directions and distributed in a spiral structure along one direction. This allows the arch-breaking device 52 to rotate as it moves forward, guided by the reaction force received by the spirally distributed arch-breaking teeth 5221, thus better ensuring that the arch-breaking device 52 rotates passively.

[0060] Specifically, in one embodiment, the bearing 523 is a spherical bearing.

[0061] Preferably, in one embodiment, the arch-breaking head 522 has a tapering structure from the direction near the arch-breaking main axis 521 to the direction away from the arch-breaking main axis 521. For example, as Figure 5 As shown, the arch-breaking head 522 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 52 to impact and break the petroleum coke.

[0062] Preferably, in one embodiment, the linear drive unit 51 is an electro-hydraulic cylinder. By using an electro-hydraulic cylinder as a power source, the arch-breaking mechanism 50 has a large thrust, as well as good control accuracy and stability.

[0063] Preferably, in one embodiment, multiple arch-breaking mechanisms 50 are provided, and the multiple arch-breaking mechanisms 50 are distributed sequentially and at intervals along the circumference of the lower silo 15. Each arch-breaking mechanism 50 is provided with an arch-breaking opening 151, that is, multiple arch-breaking openings 151 are also provided on the silo wall of the lower silo 15, and one arch-breaking opening 151 corresponds to one arch-breaking mechanism 50, so that the arch-breaking device 52 of each arch-breaking mechanism 50 can extend into the lower silo 15 to perform arch-breaking operations. By providing multiple arch-breaking mechanisms 50 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 15, and can further increase the arch-breaking effect and efficiency.

[0064] Understandably, to avoid interference between the various anti-bridging mechanisms 50 during operation, the various anti-bridging mechanisms 50 can operate sequentially. For example, when one anti-bridging mechanism 50 retracts, another anti-bridging mechanism 50 can extend. Furthermore, the maximum stroke points of the various anti-bridging mechanisms 50 may not be at the same point. The maximum stroke points of the various anti-bridging mechanisms 50 can be sequentially distributed in a ring-shaped area above the discharge port 12. That is, the maximum stroke points of the anti-bridging mechanisms 50 are not on the central axis of the hopper 10, but deviate from the central axis, so that the maximum stroke points of the various anti-bridging mechanisms 50 are distributed in a ring-shaped area, thereby avoiding interference.

[0065] Specifically, in one embodiment, the filters in the third filter group 203 are distributed sequentially at intervals along the circumference of the lower chamber 15. To avoid interference between the anti-arch mechanism 50 and the filters of the third filter group 203, the anti-arch mechanism 50 and the filters of the third filter group 203 are staggered circumferentially.

[0066] Preferably, in one embodiment, the top of the hopper 10 is also provided with a hoist 60, which facilitates the lifting of objects.

[0067] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
