Technical Field

[0001] This application relates to the field of anti-blocking technology for high-pressure reactor discharge pipes, specifically to an anti-blocking structure for the discharge pipe of a high-pressure reactor. Background Technology

[0002] Approximately 60% of global onshore nickel resources exist in the form of laterite nickel ore. Due to its abundant reserves and ease of mining and transportation, laterite nickel ore has become a hot topic for research and development. High-pressure acid leaching is currently one of the mainstream smelting processes for laterite nickel ore. Its key technologies include slurry preheating, high-pressure acid leaching, neutralization and CCD countercurrent washing, and product production. The high-pressure reactor is the main equipment in the high-pressure acid leaching process.

[0003] Chinese patent CN207430286U discloses a pressurized hydrometallurgical continuous reactor, which includes a vertical high-pressure reactor I, a horizontal high-pressure reactor, a vertical high-pressure reactor II, and a vertical high-pressure reactor III connected in series. Adjacent reactors are connected by flow guide pipes by gravity flow due to pressure difference. Each reactor is equipped with an independent stirring device, temperature control device, heating device, cooling device, and pressure control device.

[0004] However, existing high-pressure reactors produce substances such as aluminum vanadium and iron vanadium during the reaction process, which often causes the discharge pipe of the high-pressure reactor to become clogged due to scaling. When clogged, the reactor needs to be shut down for descaling, which seriously affects production efficiency. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an anti-clogging structure for the discharge pipe of a high-pressure reactor, thereby solving the technical problem that the discharge pipe of a high-pressure reactor often needs to be shut down for descaling due to scaling and blockage, which seriously affects production efficiency.

[0006] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution:

[0007] This application provides an anti-clogging structure for the discharge pipe of a high-pressure reactor, comprising: an installation structure, an ultrasonic transducer, and a driving structure. The installation structure is disposed on one side of the discharge pipe and includes an installation channel and an installation component. The installation channel communicates with the interior of the discharge pipe, and the installation component is slidably disposed within the installation channel. The ultrasonic transducer is mounted on the installation component. The driving structure is connected to the installation component and is used to drive the installation component to slide within the installation channel, thereby pressing the ultrasonic transducer against the inner wall of the discharge pipe.

[0008] In some embodiments, the mounting structure further includes a mounting housing and a removable housing, the mounting housing being connected to one side of the discharge pipe via a first flange, the removable housing being connected to the mounting housing via a second flange, and an mounting channel perpendicular to the discharge pipe being formed between the interiors of the mounting housing and the removable housing.

[0009] In some embodiments, the sliding path of the mounting component within the mounting channel forms a first station and a second station. When the mounting component is in the first station, the ultrasonic transducer is disposed inside the discharge pipe. When the mounting component is in the second station, both the ultrasonic transducer and the mounting component are located inside the detachable housing.

[0010] In some embodiments, the anti-clogging structure of the high-pressure reactor discharge pipe further includes a sealing element, which is connected to the mounting housing. A sealing channel is formed inside the mounting housing that extends laterally through the mounting channel. The sealing end of the sealing element is slidably disposed within the sealing channel to seal or open the mounting channel.

[0011] In some embodiments, the seal includes a second movable sealing plug, a second threaded rod, and a second handle. The second movable sealing plug is slidably disposed in the sealing channel, and a second threaded groove is formed on one side along the length direction. One end of the second threaded rod is threadedly connected to the second threaded groove, and the other end passes through one side of the mounting housing and is connected to the second handle.

[0012] In some embodiments, the width of the sealing channel is greater than the width of the mounting channel.

[0013] In some embodiments, the mounting component includes a first movable sealing plug and a mounting bracket. The first movable sealing plug is slidably disposed inside the mounting channel, and the mounting bracket is disposed on the side of the first movable sealing plug near the discharge pipe. The mounting bracket is provided with a mounting groove and a threaded fixing groove corresponding to the mounting groove.

[0014] In some embodiments, the drive structure includes a first threaded rod and a first handle. The first movable sealing plug has a first threaded groove at one end away from the mounting bracket. One end of the first threaded rod is threadedly connected to the first threaded groove, and the other end passes through one side of the removable housing and is connected to the first handle.

[0015] In some embodiments, the ultrasonic transducer is arranged in a ring.

[0016] In some embodiments, the ultrasonic transducer includes a plurality of ultrasonic units, which are arranged in a ring and have one side attached to the wall of the discharge pipe and the other side extending toward the middle of the discharge pipe.

[0017] Compared with existing technologies, the anti-clogging structure for the discharge pipe of the high-pressure reactor provided in this application, through the setting of an installation structure, an ultrasonic transducer, and a driving structure, allows the installation structure to be connected to one side of the discharge pipe and can be installed in a location prone to blockage. The installation component is used to fix the ultrasonic transducer. After installation, the ultrasonic transducer extends from one side of the pipe into the interior of the discharge pipe and, driven by the driving structure, makes close contact with the inner wall of the discharge pipe. The ultrasonic energy generated by the ultrasonic transducer can produce high-frequency vibrations inside the pipe. These vibrations can disrupt the adhesion between material particles, preventing material from depositing on the inner wall of the pipe. Simultaneously, the ultrasonic transducer, positioned inside the discharge pipe and in direct contact with the material, can better transmit ultrasonic energy, allowing the generated vibrations to better promote material flow within the pipe and reduce the likelihood of blockage. Therefore, this device effectively reduces the adhesion and accumulation of material inside the pipe, thereby lowering the risk of pipe blockage. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] To address the technical problem that high-pressure reactors frequently require shutdown for descaling due to scaling and blockage in the discharge pipe, severely impacting production efficiency, this application provides an anti-blockage structure for the discharge pipe of a high-pressure reactor. This structure effectively reduces the adhesion and accumulation of materials inside the pipe, thereby lowering the risk of pipe blockage.

[0031] Please see Figures 1 to 5 The anti-clogging structure for the discharge pipe of the high-pressure reactor is used to be installed on the discharge pipe 6 of the high-pressure reactor body 5. It includes: a mounting structure 1, an ultrasonic transducer 2, and a driving structure 3. The mounting structure 1 is located on one side of the discharge pipe 6 and includes a mounting channel 101 and a mounting component. The mounting channel 101 communicates with the interior of the discharge pipe 6. The mounting component is slidably disposed within the mounting channel 101. The ultrasonic transducer 2 is mounted on the mounting component. The driving structure 3 is connected to the mounting component and is used to drive the mounting component to slide within the mounting channel 101, thereby pressing the ultrasonic transducer 2 against the inner wall of the discharge pipe 6.

[0032] In this device, the mounting structure 1 is connected to the discharge pipe 6 on one side. It can be installed in a location on the discharge pipe 6 that is prone to blockage, such as near the discharge port of the high-pressure reactor. The mounting structure 1 includes a mounting channel 101 that communicates with the interior of the discharge pipe 6 and a mounting component that is slidably disposed inside the mounting channel 101. The mounting component is used to fix the ultrasonic transducer 2. After installation, the ultrasonic transducer 2 can extend from one side of the pipe into the interior of the discharge pipe 6 and, under the driving action of the driving structure 3, make close contact with the inner wall of the discharge pipe 6. The ultrasonic energy generated by the ultrasonic transducer 2 can generate high-frequency vibrations inside the pipe. These vibrations can break the adhesion between material particles and prevent material from depositing on the inner wall of the pipe. At the same time, the ultrasonic transducer 2 is disposed inside the discharge pipe 6 and in direct contact with the material, which can better transmit ultrasonic energy and make the generated vibrations better promote the flow of material in the pipe and reduce the possibility of blockage.

[0033] It should be noted that this solution also includes a drive circuit, a control system, and a power supply, which work in conjunction with the ultrasonic transducer 2 to convert electrical energy into ultrasonic mechanical vibration energy. The ultrasonic transducer 2 works with the drive circuit to provide the necessary voltage and current to excite the transducer to generate ultrasonic waves. The drive circuit can be a simple oscillation circuit or a complex closed-loop control system. The control system manages the operating state of the ultrasonic transducer 2, including switching control, frequency adjustment, and power regulation.

[0034] To install the mounting components, please refer to the following in this embodiment: Figures 2 to 4 The mounting structure 1 further includes a mounting housing 13 and a detachable housing 14. One side of the mounting housing 13 is connected to one side of the discharge pipe 6 via a first flange, thereby achieving a sealed connection between the mounting housing 13 and the discharge pipe 6. The detachable housing 14 is connected to the other side of the mounting housing 13 via a second flange, allowing the detachable housing 14 to be disassembled. An installation channel 101 perpendicular to the discharge pipe 6 is formed between the interiors of the mounting housing 13 and the detachable housing 14, allowing the mounting component to be movably disposed between the interiors of the mounting housing 13 and the detachable housing 14.

[0035] The mounting component has a sliding path within the mounting channel 101 forming a first station and a second station. When the mounting component is in the first station, the ultrasonic transducer 2 is located inside the discharge pipe 6. At this time, the ultrasonic transducer 2 is in working condition and is used to generate high-frequency vibration to prevent blockage. When the mounting component is in the second station, both the ultrasonic transducer 2 and the mounting component are located inside the detachable outer casing 14.

[0036] In one embodiment, please refer to Figure 4 The mounting component includes a first movable sealing plug 11 and a mounting bracket 12. The first movable sealing plug 11 is slidably disposed inside the mounting channel 101, that is, it can slide between the mounting housing 13 and the detachable housing 14. The mounting bracket 12 is fixedly disposed on the side of the first movable sealing plug 11 near the discharge pipe 6. The mounting bracket 12 is provided with a mounting groove and a threaded fixing groove corresponding to the mounting groove. The mounting groove is used to place the ultrasonic transducer 2, and the threaded fixing groove is used to cooperate with bolts to fix the ultrasonic transducer 2 to the mounting bracket 12.

[0037] In order to drive the mounting component to move between the first and second stations, in one embodiment, please refer to Figures 2 to 4The drive structure 3 includes a first threaded rod 31 and a first handle 32. The first movable sealing plug 11 has a first threaded groove 111 at one end facing away from the mounting bracket 12. One end of the first threaded rod 31 is threadedly connected to the first threaded groove 111, and the other end passes through one side of the detachable housing 14 and connects to the first handle 32. The connection between the first threaded rod 31 and the detachable housing 14 is a sealed connection. In implementation, the first handle 32 is used to rotate the first threaded rod 31. One end of the first threaded rod 31 is threadedly connected to the first threaded groove 111 of the first movable sealing plug 11, allowing the first threaded rod 31 to rotate and drive the first movable sealing plug 11 to slide between the mounting housing 13 and the detachable housing 14. This enables the installation component to move between the first and second workstations. After the ultrasonic transducer 2 is installed, the first movable sealing plug 11 can form a seal with the mounting housing 13, preventing slurry leakage.

[0038] In practical applications, the ultrasonic transducer 2 may malfunction and require maintenance, repair, or replacement. To ensure the proper functioning of the discharge pipe 6 during the assembly and disassembly of the ultrasonic transducer 2, please refer to the following in this embodiment: Figure 5 The anti-clogging structure of the discharge pipe of the high-pressure reactor is also provided with a sealing element 4. The sealing element 4 is connected to the mounting shell 13. Specifically, a sealing channel 131 that extends horizontally through the mounting channel 101 is also formed inside the mounting shell 13. The sealing end of the sealing element 4 is slidably disposed in the sealing channel 131 to seal or open the mounting channel 101 when sliding.

[0039] In one embodiment, please refer to Figures 2 to 5 The sealing element 4 includes a second movable sealing plug 41, a second threaded rod 42, and a second handle 43. The second movable sealing plug 41 is slidably disposed in the sealing channel 131, and a second threaded groove 411 is formed on one side along the length direction. One end of the second threaded rod 42 is threadedly connected to the second threaded groove 411, and the other end passes through one side of the mounting housing 13 and is fixedly connected to the second handle 43. The connection position between the second threaded rod 42 and the mounting housing 13 is a sealed connection.

[0040] In practice, the second handle 43 is used to rotate the second threaded rod 42. One end of the second threaded rod 42 is threadedly connected to the second threaded groove 411 of the second movable sealing plug 41. This rotation of the second threaded rod 42 causes the second movable sealing plug 41 to slide within the sealing channel 131 of the mounting housing 13. When it moves towards the mounting channel 101, it seals the mounting channel 101. When it moves away from the mounting channel 101, it moves away from the mounting channel 101 and opens the mounting channel 101. When the ultrasonic transducer 2 needs maintenance or replacement, the second movable sealing plug 41 can seal the side opening of the discharge pipe 6, allowing the discharge pipe 6 to function normally during the assembly and disassembly of the ultrasonic transducer 2.

[0041] Furthermore, in some embodiments, the width of the sealing channel 131 is greater than the width of the mounting channel 101.

[0042] It should be noted that the anti-clogging structure is installed at the discharge pipe 6 of the high-pressure reactor body 5. The slurry is in a high-temperature and high-pressure conveying environment. Therefore, the first movable sealing plug 11 and the second movable sealing plug 41 need to be able to withstand high temperature and high pressure. Thus, the first movable sealing plug 11 and the second movable sealing plug 41 can be made of materials that can withstand high temperature and high pressure, such as metal materials, ceramic materials or composite materials, such as stainless steel, nickel-based alloys, titanium alloys, alumina, silicon carbide (SiC), silicon nitride (Si3N4) or graphite-reinforced composite materials.

[0043] Preferably, in this embodiment, the ultrasonic transducer 2 is arranged in a ring shape and is directly mounted on the annular mounting groove of the mounting bracket 12 by bolts. After the ultrasonic transducer 2 is set on the discharge pipe 6, it can make uniform contact with the pipe wall of the discharge pipe 6, which can make the ultrasonic energy distribution more uniform and reduce hot spots or blind spots.

[0044] Of course, in some other embodiments, the ultrasonic transducer 2 can also be configured to consist of multiple ultrasonic units, each of which is arranged in a ring to form a ring-shaped transducer. The ultrasonic units are mounted on the mounting bracket 12 in a ring-shaped array in the mounting groove by bolts. One side of each ultrasonic unit is attached to the wall of the discharge pipe 6, and the other side extends toward the middle of the discharge pipe 6. This arrangement can increase the contact between the ultrasonic transducer 2 and the slurry and promote the flow of materials in the pipe.

[0045] Working principle: During implementation, the ultrasonic transducer 2 is installed on the feed pipe under the action of the drive structure 3 and the mounting parts, and is in close contact with the inner wall of the discharge pipe 6. The ultrasonic energy generated by the ultrasonic transducer 2 can generate high-frequency vibration inside the pipe, and at the same time promote the flow of materials in the pipe, reducing the possibility of pipe blockage. When the ultrasonic transducer 2 needs maintenance or replacement, the first handle 32 is used to rotate the first threaded rod 31, which drives the first movable sealing plug 11 to slide between the mounting shell 13 and the detachable shell 14 until the first movable sealing plug 11 and the mounting bracket 12 slide into the interior of the detachable shell 14. Then, the second handle 43 is used to rotate the second threaded rod 42, which drives the second movable sealing plug 41 to slide in the sealing channel 131 of the mounting shell 13, so that the second movable sealing plug 41 seals the mounting channel 101. The detachable shell 14 can then be removed to perform maintenance or replacement of the ultrasonic transducer 2. At this time, the discharge pipe 6 can be used normally.

[0046] This application employs an installation structure 1, an ultrasonic transducer 2, and a drive structure 3. The installation structure 1 connects to one side of the discharge pipe 6 and can be installed at locations prone to blockage. The installation component secures the ultrasonic transducer 2. After installation, the ultrasonic transducer 2 extends from one side of the pipe into the interior of the discharge pipe 6 and, driven by the drive structure 3, makes close contact with the inner wall of the discharge pipe 6. The ultrasonic energy generated by the ultrasonic transducer 2 produces high-frequency vibrations inside the pipe. These vibrations disrupt the adhesion between material particles, preventing material deposition on the inner wall of the pipe. Simultaneously, the ultrasonic transducer 2, positioned inside the discharge pipe 6 and in direct contact with the material, allows for better transmission of ultrasonic energy. The generated vibrations promote material flow within the pipe, reducing the likelihood of blockage. Therefore, this device effectively reduces material adhesion and accumulation inside the pipe, thereby lowering the risk of blockage.

[0047] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
