Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a high-temperature resistant centrifuge. Background Technology

[0002] In industrial fields such as chemical and food processing, it is often necessary to perform solid-liquid separation of high-temperature materials (such as high-temperature reaction liquids and high-temperature slurries). As a high-efficiency separation device, the centrifuge is one of the core equipment for realizing this process and needs to meet the operational requirements of long-term continuous separation of high-temperature materials.

[0003] Currently, conventional centrifuges used for separating high-temperature materials rely mainly on periodic oil changes for lubrication of their transmission mechanisms. This involves manually disassembling the equipment at fixed intervals, draining the old lubricating oil, and adding new lubricating oil to maintain basic lubrication.

[0004] When conventional centrifuges process high-temperature materials, the heat from the high-temperature materials is continuously conducted to the transmission mechanism through the drum, casing, and spiral. However, periodically changing the lubricating oil only replenishes the oil periodically and cannot remove the heat generated by the transmission mechanism in real time and continuously. This causes a large amount of heat to accumulate in the transmission mechanism, which can easily lead to transmission mechanism failure and directly affect the stable operation of the equipment in high-temperature material separation scenarios.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a high-temperature resistant centrifuge to solve the problem of heat accumulation due to the inability to remove heat in real time, and to ensure that the equipment can operate continuously and stably for a long time in high-temperature material separation scenarios.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A high-temperature resistant centrifuge includes a shell, a separation mechanism, a transmission mechanism, an oil supply mechanism, and a cooling mechanism, wherein:

[0009] The housing includes a transmission cavity and a separation cavity;

[0010] The separation mechanism is disposed within the separation chamber and is configured to perform solid-liquid separation on the material within the separation chamber.

[0011] The transmission mechanism is disposed within the transmission cavity and has a drive portion extending into the separation cavity to drive the separation mechanism to operate via the drive portion;

[0012] The oil supply mechanism includes an oil storage unit and a conveying component. The oil storage unit is used to store lubricating oil, and the conveying component is used to convey the lubricating oil in the oil storage unit to the transmission mechanism and to send the lubricating oil from the transmission mechanism back to the oil storage unit, so as to realize the cyclic supply of lubricating oil to the transmission mechanism.

[0013] The cooling mechanism is configured to cool the lubricating oil supplied by the oil supply mechanism.

[0014] Preferably, the delivery component of the oil supply mechanism includes an oil pump, an oil inlet pipe, and an oil return pipe, wherein:

[0015] The oil pump is installed in the oil storage unit, and the oil outlet of the oil pump is connected to the oil inlet of the transmission mechanism through the oil inlet pipe, so as to pump the lubricating oil in the oil storage unit into the transmission mechanism through the oil pump.

[0016] The transmission mechanism includes at least one oil outlet, which is provided corresponding to the bearing outside the transmission mechanism, so that lubricating oil flows from inside the transmission mechanism to the bearing outside, and the lubricating oil collects at the bottom of the transmission cavity;

[0017] The bottom of the transmission chamber is connected to the oil storage unit through the oil return pipe, so that the lubricating oil flows back into the oil storage unit.

[0018] Preferably, the cooling mechanism includes a first cooling pipe disposed within the oil storage unit, through which external coolant can flow to exchange heat and cool the lubricating oil within the oil storage unit.

[0019] Preferably, the cooling mechanism further includes a second cooling pipe corresponding to the oil inlet pipe, through which external coolant can flow to exchange heat and cool the lubricating oil transported in the oil inlet pipe.

[0020] Preferably, the cooling mechanism further includes at least one liquid supply component configured to supply coolant to the first cooling pipe and / or the second cooling pipe;

[0021] When one of the liquid supply components is provided, the output end of the liquid supply component is connected to the inlet of the first cooling pipe and the inlet of the second cooling pipe, respectively, so as to supply coolant to the first cooling pipe and the second cooling pipe simultaneously.

[0022] When two liquid supply components are provided, the output end of one liquid supply component is connected to the inlet of the first cooling pipe, and the output end of the other liquid supply component is connected to the inlet of the second cooling pipe, so as to supply coolant to the first cooling pipe and the second cooling pipe separately.

[0023] Preferably, the oil supply mechanism further includes a detection component disposed on the oil inlet pipe corresponding to the conveying component. The detection component is configured to detect the conveying status of the lubricating oil in the oil inlet pipe in order to determine whether the oil supply mechanism is operating normally.

[0024] Preferably, the detection assembly includes a detection tube, a float, and a proximity switch, wherein:

[0025] The detection tube is connected in series with the oil inlet pipe to communicate with the oil inlet pipe and to supply lubricating oil.

[0026] The float is movably disposed inside the detection tube;

[0027] The proximity switch is mounted on the detection tube and corresponds to a preset position where the float floats.

[0028] When the oil inlet pipe delivers lubricating oil, the oil supply pressure can push the float to the preset position, and the proximity switch can detect the float signal to indicate that the oil supply mechanism is normal.

[0029] When the oil inlet pipe does not deliver lubricating oil or the oil supply pressure is insufficient, the float cannot rise to the preset position, and the proximity switch cannot detect the float signal, indicating that the oil supply mechanism is abnormal.

[0030] Preferably, the high-temperature centrifuge further includes an isolation mechanism disposed between the transmission chamber and the separation chamber, which can prevent water vapor from entering the transmission chamber from the separation chamber when water vapor is generated in the separation chamber.

[0031] Preferably, the isolation mechanism includes an inflation chamber and an inflation assembly, wherein:

[0032] The inflation chamber is located between the transmission chamber and the separation chamber, and inflation ports and exhaust ports are provided on opposite sides of the inflation chamber.

[0033] The inflation assembly is configured to inflate gas into the inflation chamber through the inflation port. The gas inflated into the inflation chamber flows along the inside of the inflation chamber and is discharged from the exhaust port, forming a continuous airflow in the inflation chamber to achieve airtight isolation between the transmission chamber and the separation chamber, thereby preventing water vapor in the separation chamber from entering the transmission chamber.

[0034] Preferably, the gas filled into the inflation chamber by the inflation assembly is compressed air or nitrogen.

[0035] The beneficial effects of this utility model are:

[0036] This invention utilizes the synergistic action of an oil supply mechanism and a cooling mechanism. First, the conveying component establishes a lubricating oil circulation path, carrying away the dual heat generated by material conduction and friction within the transmission mechanism along with the lubricating oil. Simultaneously, the cooling mechanism cools the heat-carrying lubricating oil in real time, addressing the problem of heat accumulation due to failure to remove heat promptly. Furthermore, it continuously maintains the transmission mechanism temperature within a reasonable range. When the cooled lubricating oil re-enters the transmission mechanism, it simultaneously removes newly generated heat, ensuring long-term, continuous, and stable operation of the equipment in high-temperature material separation scenarios.

[0054] Please see Figures 1 to 3 This embodiment provides a high-temperature resistant centrifuge, which includes a housing 1, a separation mechanism 2, a transmission mechanism 3, an oil supply mechanism 4, and a cooling mechanism. The housing 1 includes a transmission chamber 11 and a separation chamber 12. The separation mechanism 2 is disposed within the separation chamber 12 and is configured to perform solid-liquid separation of the material within the separation chamber 12. The transmission mechanism 3 is disposed within the transmission chamber 11 and has a drive unit extending into the separation chamber 12 to drive the separation mechanism 2. The oil supply mechanism 4 includes an oil storage unit 41 and a conveying assembly 42. The oil storage unit 41 stores lubricating oil, and the conveying assembly 42 conveys the lubricating oil from the oil storage unit 41 to the transmission mechanism 3 and returns the lubricating oil from the transmission mechanism 3 to the oil storage unit 41, thereby achieving a cyclic supply of lubricating oil to the transmission mechanism 3. The cooling mechanism is configured to cool the lubricating oil supplied by the oil supply mechanism 4.

[0055] During operation, the transmission mechanism 3 drives the separation mechanism 2 through the drive unit, and the conveying component 42 of the oil supply mechanism 4 continuously delivers the lubricating oil in the oil storage unit 41 to the transmission mechanism 3, and then sends the lubricating oil flowing through the transmission mechanism 3 back to the oil storage unit 41. At the same time, the cooling mechanism cooperates with the oil supply mechanism 4 to cool the circulating lubricating oil, so that the lubricating oil that is delivered to the transmission mechanism 3 again through the conveying component 42 is cooled.

[0056] This configuration, through the coordinated action of the oil supply mechanism 4 and the cooling mechanism, firstly establishes a lubricating oil circulation path via the conveying component 42, carrying away the dual heat generated by material conduction and self-friction in the transmission mechanism 3 along with the lubricating oil in real time. Simultaneously, the cooling mechanism cools the lubricating oil carrying heat in real time, solving the problem of heat accumulation due to the inability to remove heat in a timely manner from the source. Furthermore, it continuously controls the temperature of the transmission mechanism 3 within a reasonable range. When the cooled lubricating oil re-enters the transmission mechanism 3, it can simultaneously remove newly generated heat, thus ensuring long-term, continuous, and stable operation of the equipment in high-temperature material separation scenarios.

[0057] It should be noted that this embodiment does not make any improvements to the specific structure and working principle of the transmission mechanism 3 and the separation mechanism 2, so they will not be described in detail.

[0058] Specifically, the delivery component 42 of the oil supply mechanism 4 includes an oil pump, an oil inlet pipe 421, and an oil return pipe 422. The oil pump is located inside the oil storage unit 41, and its outlet is connected to the oil inlet of the transmission mechanism 3 via the oil inlet pipe 421, so as to pump the lubricating oil in the oil storage unit 41 into the transmission mechanism 3. The transmission mechanism 3 includes at least one oil outlet 31, which corresponds to the bearing outside the transmission mechanism 3, so that the lubricating oil flows from inside the transmission mechanism 3 to the bearing outside and collects at the bottom of the transmission cavity 11. The bottom of the transmission cavity 11 is connected to the oil storage unit 41 via the oil return pipe 422, so that the lubricating oil flows back into the oil storage unit 41. In this embodiment, there are two oil outlets 31, and the two oil outlets 31 correspond to two bearings outside the transmission mechanism 3, respectively.

[0059] It is understandable that the oil outlet 31 of the transmission mechanism 3 is set to correspond to the external bearing, so that the lubricating oil can flow directly to the bearing, avoiding the problem of insufficient oil in the external bearing in conventional lubrication methods, ensuring that the bearing is always in a fully lubricated state, and reducing the problem of increased friction caused by insufficient lubrication.

[0060] It is also understandable that the oil pump is located inside the oil storage unit 41, which can directly draw lubricating oil from the oil storage unit 41 and actively pump it into the transmission mechanism 3 through the oil inlet pipe 421. At the same time, after the lubricating oil flows through the inside of the transmission mechanism 3 and the external bearings, it can collect at the bottom of the transmission cavity 11 and then flow back to the oil storage unit 41 through the oil return pipe 422, forming a complete closed loop and realizing the active and continuous circulation of lubricating oil.

[0061] More importantly, during the circulation process, the lubricating oil first flows through the interior of the transmission mechanism 3 to absorb its frictional heat and the heat conducted by the material, and then flows to the external bearing to simultaneously carry away the frictional heat and the heat conducted by the bearing, covering the core heat-generating area of ​​the transmission mechanism 3. Subsequently, the lubricating oil carrying heat gathers at the bottom of the transmission cavity 11 and flows back through the return oil pipe 422, which can completely remove the heat from the interior of the transmission mechanism 3 and the bearing, avoiding localized heat accumulation near key components (especially the bearing), and providing an efficient heat transfer path for the subsequent cooling mechanism to cool the lubricating oil.

[0062] In this embodiment, the cooling mechanism includes a first cooling pipe disposed within the oil storage unit 41. External coolant can flow through the first cooling pipe to exchange heat and cool the lubricating oil within the oil storage unit 41. The first cooling pipe is directly disposed inside the oil storage unit 41, allowing for close-range or direct contact heat exchange with the high-temperature lubricating oil returning to the oil storage unit 41. This eliminates the need for heat transfer through intermediate media such as the outer shell of the oil storage unit 41, significantly shortening the heat transfer path, reducing heat loss, and enabling faster absorption of heat from the lubricating oil and its removal by the coolant, thus efficiently lowering the lubricating oil temperature.

[0063] Furthermore, the cooling mechanism also includes a second cooling pipe corresponding to the oil inlet pipe 421. External coolant can flow through the second cooling pipe to exchange heat and cool the lubricating oil transported in the oil inlet pipe 421. This arrangement allows for further heat exchange and cooling of the lubricating oil about to be pumped into the transmission mechanism 3, thereby further reducing the initial temperature of the lubricating oil. This enables the low-temperature lubricating oil to have a stronger heat absorption capacity after entering the transmission mechanism 3, and can more efficiently remove the frictional heat and material conduction heat generated by the transmission mechanism 3 in real time, significantly improving the heat control effect in the core area of ​​the transmission mechanism 3.

[0064] Furthermore, during the process of lubricating oil being transported from the oil storage unit 41 to the transmission mechanism 3 via the oil inlet pipe 421, the oil inlet pipe 421 is prone to absorbing ambient heat due to its proximity to the transmission cavity 11, causing the oil temperature to rise. The second cooling pipe directly cools the lubricating oil in the oil inlet pipe 421, which can offset the additional heat absorbed during the transportation process in real time, avoiding the problem of the cooled lubricating oil reheating during transportation, and ensuring that the lubricating oil entering the transmission mechanism 3 is always at the target low temperature.

[0065] To adapt to different operating conditions, the cooling mechanism also includes at least one liquid supply component, which is configured to supply coolant to the first cooling pipe and / or the second cooling pipe.

[0066] When a liquid supply assembly is installed, the output end of the liquid supply assembly is connected to the inlet of the first cooling pipe and the inlet of the second cooling pipe, respectively, so as to supply coolant to the first cooling pipe and the second cooling pipe simultaneously.

[0067] When two liquid supply components are installed, the output end of one liquid supply component is connected to the inlet of the first cooling pipe, and the output end of the other liquid supply component is connected to the inlet of the second cooling pipe, so as to supply coolant to the first cooling pipe and the second cooling pipe separately.

[0068] As can be seen from the above, when only one liquid supply component is set up, liquid can be supplied to the first cooling pipe and the second cooling pipe simultaneously through pipeline branches, without the need for additional independent power and control units, thereby reducing the number of equipment components (such as pump body, valves, control modules, etc.), simplifying the overall layout, and reducing the manufacturing cost of the equipment.

[0069] By setting up two coolant supply components, the amount of coolant flowing through the first and second cooling pipes can be independently and precisely controlled, thereby improving system reliability. On the one hand, since the first cooling pipe is responsible for cooling the return lubricating oil in the oil storage unit 41 and the second cooling pipe is responsible for cooling the lubricating oil in the oil inlet pipe 421 that is about to enter the transmission mechanism 3, the amount of oil to be cooled and the initial oil temperature are different. The two coolant supply components can adjust the flow rate and pressure of the two coolants respectively to precisely match the cooling requirements of the first and second cooling pipes. On the other hand, if one coolant supply component fails, the other can still supply coolant to the corresponding first or second cooling pipe normally, ensuring that the cooling function is not interrupted, avoiding the transmission mechanism 3 from rapidly heating up due to complete loss of cooling, and significantly improving the reliability of the high-temperature centrifuge under high load and long cycle operation.

[0070] It should be noted that the specific structure of the coolant supply assembly includes a drive unit (such as a centrifugal pump), an inlet pipe, an outlet pipe, and a flow control valve. The drive unit draws coolant from an external coolant source through the inlet pipe and delivers it to the first or second cooling pipe through the outlet pipe. Simultaneously, the flow control valve regulates the coolant delivery rate. After heat exchange with lubricating oil within the cooling pipe, the coolant is discharged through the return pipe, forming a coolant circulation. When one coolant supply assembly is installed, its outlet pipe is connected to the inlets of the first and second cooling pipes via branch pipes. Each branch pipe is equipped with a flow control valve, which can be adjusted to distribute the coolant volume to the two cooling pipes, achieving simultaneous coolant supply to both pipes. When two coolant supply assemblies are installed, their structures are independent. One assembly's outlet pipe is directly connected to the inlet of the first cooling pipe, and the other's outlet pipe is directly connected to the inlet of the second cooling pipe. Each assembly regulates its coolant delivery rate through its own drive unit and flow control valve, achieving individual coolant supply to the two cooling pipes.

[0071] To ensure that the oil supply mechanism 4 can continuously and stably supply lubricating oil to the transmission mechanism 3, the oil supply mechanism 4 also includes a detection component 5 provided in the oil inlet pipe 421 corresponding to the conveying component 42. The detection component 5 is configured to detect the conveying status of the lubricating oil in the oil inlet pipe 421 in order to determine whether the oil supply mechanism 4 is operating normally.

[0072] Understandably, the oil inlet pipe 421 serves as the direct channel for lubricating oil to flow from the oil storage unit 41 to the transmission mechanism 3. The delivery status of the lubricating oil inside it directly reflects whether the oil supply mechanism 4 is functioning properly. This allows for real-time monitoring of the critical delivery process before the lubricating oil enters the transmission mechanism 3, thereby accurately determining the operating status of the oil supply mechanism 4.

[0073] In this embodiment, the detection component 5 includes a detection tube 51, a float, and a proximity switch 52. The detection tube 51 is connected in series with the oil inlet pipe 421 to communicate with and supply lubricating oil. The float is movably disposed inside the detection tube 51. The proximity switch 52 is disposed on the detection tube 51 and corresponds to a preset position where the float floats. When the oil inlet pipe 421 supplies lubricating oil, the oil supply pressure can push the float to the preset position, and the proximity switch 52 can detect the float signal to indicate that the oil supply mechanism 4 is normal. When the oil inlet pipe 421 does not supply lubricating oil or the oil supply pressure is insufficient, the float cannot float to the preset position, and the proximity switch 52 cannot detect the float signal to indicate that the oil supply mechanism 4 is abnormal.

[0074] With this configuration, the detection tube 51 is directly connected to the oil inlet pipe 421. The floating state of the float is directly related to the oil supply pressure and flow rate of the lubricating oil in the oil inlet pipe 421. When the pressure is sufficient, the float reaches the preset position; when the pressure is insufficient or the supply is interrupted, the float falls. This ensures that the detection result accurately reflects the operating status of the oil supply mechanism 4, avoiding signal deviations that may occur with indirect detection. It should be noted that both the float and the proximity switch 52 are existing technologies, and their specific models can be selected according to the actual application scenario. This embodiment does not impose specific requirements or limitations on them.

[0075] It should be noted that the above-mentioned detection components 5 can be set in two sets, connected in parallel to the oil inlet pipe 421. Each set is equipped with an independent control valve, achieving one set for backup and one set for use. Under normal operating conditions, one set of detection components 5 is in working state (its control valve is open and connected to the oil inlet pipe 421 passage), and the other set is in standby state (its control valve is closed and isolated from the oil inlet pipe 421 passage). When the working group malfunctions (such as float jamming or proximity switch 52 failure), its control valve can be closed manually or automatically by the control module, while the control valve of the standby set is opened, so that the detection pipe 51 of the standby set is connected to the oil inlet pipe 421 passage, taking over the detection of the lubricating oil delivery status and ensuring uninterrupted continuous monitoring of the operating status of the oil supply mechanism 4.

[0076] Generally, water vapor is easily generated when high-temperature materials are processed in the separation chamber 12 (such as evaporation of high-temperature slurry or vaporization of reaction liquid). If water vapor enters the transmission chamber 11, it will directly contact transmission components such as bearings and gears, which may cause corrosion and jamming of the components. At the same time, it will also mix into the lubricating oil and damage its lubrication performance. For this reason, the high-temperature centrifuge also includes an isolation mechanism set between the transmission chamber 11 and the separation chamber 12. The isolation mechanism can prevent water vapor from entering the transmission chamber 11 from the separation chamber 12 when water vapor is generated in the separation chamber 12, so as to ensure the mechanical performance and operational stability of the transmission mechanism 3.

[0077] Preferably, the isolation mechanism includes an inflation chamber 6 and an inflation assembly. The inflation chamber 6 is disposed between the transmission chamber 11 and the separation chamber 12, and inflation ports 61 and exhaust ports are provided on opposite sides of the inflation chamber 6. The inflation assembly is configured to inject gas into the inflation chamber 6 through the inflation ports 61. The gas injected into the inflation chamber 6 flows along the interior of the inflation chamber 6 and is discharged from the exhaust ports, forming a continuous airflow within the inflation chamber 6 to achieve airtight isolation between the transmission chamber 11 and the separation chamber 12, thereby preventing water vapor in the separation chamber 12 from entering the transmission chamber 11.

[0078] The inflation component continuously injects gas into the inflation chamber 6, forming a continuous airflow. This dynamically maintains a stable air pressure within the inflation chamber 6, preventing the static seal from deteriorating due to aging and wear over long-term use. Even if the water vapor concentration in the separation chamber 12 fluctuates, the continuous airflow can always form an airflow barrier between the two chambers, fundamentally blocking the water vapor intrusion path and ensuring a long-term sealing effect.

[0079] In addition, the continuous airflow can not only physically block the water vapor in the separation chamber 12 from spreading to the transmission chamber 11, but also actively guide the small amount of water vapor near the inflation chamber 6. That is, some water vapor that has seeped into the edge of the inflation chamber 6 will be carried by the airflow and discharged from the exhaust port with the airflow, thus preventing water vapor from accumulating in the inflation chamber 6 and then seeping into the transmission chamber 11. Compared with relying solely on static sealing, this further reduces the risk of water vapor breaking through the isolation.

[0080] Furthermore, the gas used to fill the inflation chamber 6 is compressed air or nitrogen. Industrial sites are commonly equipped with compressed air systems (such as air compressors). This means that using a compressed air system as the inflation component eliminates the need for additional procurement and storage of dedicated air sources; it can be directly connected to the inflation chamber 6, significantly reducing air source acquisition and maintenance costs, making it suitable for cost-sensitive conventional separation scenarios. In addition, nitrogen is a chemically inert gas and contains no moisture. On one hand, it prevents moisture carried by the gas itself from entering the inflation chamber 6; on the other hand, if the material in the separation chamber 12 is easily oxidized (such as certain high-temperature metal powders or organic compounds), nitrogen can indirectly isolate it from air, preventing the material from reacting with oxygen, thus serving the dual purpose of isolating moisture and protecting the material.

[0081] It should be noted that the inflation assembly can use industrial-grade nitrogen cylinders or a centralized nitrogen supply system. Its output end is connected to the inflation chamber 6 via a pressure-resistant pipeline. The pipeline is equipped with a pressure reducing valve, a flow control valve and a pressure gauge in sequence. After being treated, the nitrogen is sent into the inflation chamber 6 and discharged from the exhaust port to form a continuous nitrogen flow.
