Description

Technical Field

[0001] This application relates to the field of oil tank technology, and in particular to an oil tank for a compressor. Background Technology

[0002] During compressor operation, the oil tank, as the core component of the oil circuit system, undertakes crucial functions such as storing and transporting lubricating oil, and working with the oil heater to ensure the lubricating oil reaches the start-up temperature in low-temperature environments. The oil tank typically consists of the tank body, inlet oil line, return oil line, oil level gauge, oil heater, and discharge port. To meet the compressor's normal operating requirements under low-temperature conditions, the lubricating oil in the tank needs to be preheated to a suitable temperature by the oil heater before being transported to the compressor head through pipelines. This achieves lubrication and cooling functions, thereby extending gear life and reducing factory application costs.

[0003] However, existing compressor oil tanks have some design shortcomings. Especially in low-temperature environments, because the oil heater is usually installed at one end of the tank, uneven temperature distribution occurs in the lubricating oil during the heating process. The lubricating oil on one side may have reached the start-up temperature, while the temperature on the other side remains too low, failing to achieve rapid overall heating. Since compressors undergo performance testing at the factory, the oil tank must be filled to the brim. During transportation, the lubricating oil inside the tank poses a safety risk if there are bumps or sudden braking on the road. Utility Model Content

[0004] The purpose of this application is to provide an oil tank for a compressor. By dividing the oil tank cavity into two chambers and installing an oil heater in the first chamber connected to the oil inlet pipe, the oil can be quickly heated to the start-up temperature in low-temperature environments. At the same time, by utilizing the separating ability of the baffle plate, the shaking energy is dissipated through separate storage in multiple locations, which effectively improves the heating efficiency and transportation safety of the oil tank.

[0005] To achieve the above objectives, this application provides an oil tank for a compressor, comprising:

[0006] The oil tank body has an oil tank cavity, and the cavity wall of the oil tank cavity is provided with a first fixed mounting flange, which is used to install an oil heater.

[0007] A liquid separator is provided on the oil tank body. The liquid separator is used to divide the oil tank cavity into a first chamber and a second chamber. The first chamber and the first fixed mounting flange are located on the same side of the liquid separator.

[0008] An oil inlet pipe is provided on the oil tank body, and the oil inlet pipe is connected to the first chamber;

[0009] An oil return pipe is provided on the oil tank body, and the oil return pipe is connected to the second chamber.

[0010] In some embodiments, the liquid separator is provided with an interception structure for preventing foam generated during oil return from flowing from the second chamber to the first chamber.

[0011] In some embodiments, the interception structure is located at the top of the liquid separator and is bent from the first chamber toward the second chamber.

[0012] In some embodiments, the liquid separator is provided with a grid structure that connects the first chamber and the second chamber.

[0013] In some embodiments, the liquid-separating plate has a plate body, and a plurality of grid plates are provided at the upper end of the plate body. The plurality of grid plates are spaced apart in the length direction of the plate body, and the plurality of grid plates constitute the grid structure.

[0014] In some embodiments, the top end of the grid plate is provided with a bending body, which is bent from the first chamber toward the second chamber.

[0015] In some embodiments, the oil tank further includes an oil mist filter, which is disposed in the second chamber.

[0016] In some embodiments, the height of the bottom end of the oil inlet pipe is lower than the height of the bottom end of the oil return pipe.

[0017] In some embodiments, the wall of the oil tank cavity is further provided with a second fixed mounting flange, which is used to install an auxiliary oil pump.

[0018] In some embodiments, the fuel tank body includes a tank body and a cover plate, the cover plate being located at the top of the tank body and detachably connected to the tank body;

[0019] The oil inlet pipe and the oil return pipe are integrated into the cover plate.

[0020] Compared to the aforementioned background technology, the oil tank for a compressor provided in this application mainly includes an oil tank body, a baffle plate, an oil inlet pipe, and an oil return pipe. The oil tank body has an oil tank cavity, and the cavity wall of the oil tank cavity is provided with a first fixed mounting flange for mounting an oil heater. The baffle plate is located on the oil tank body and is used to divide the oil tank cavity into a first chamber and a second chamber. The first chamber and the first fixed mounting flange are located on the same side of the baffle plate. The oil inlet pipe is located on the oil tank body and communicates with the first chamber. The oil return pipe is located on the oil tank body and communicates with the second chamber.

[0021] In existing technologies, compressor oil tanks have low heating efficiency at low temperatures and pose safety risks during transportation. To address these issues, this application provides an oil tank for compressors whose ingenious design solves the aforementioned drawbacks.

[0022] The oil tank provided in this application mainly includes an oil tank body, a baffle plate, an oil inlet pipe, and an oil return pipe. The oil tank body has an oil tank cavity, and a first fixed mounting flange is provided on the cavity wall. This flange is specifically used to install an oil heater. This design allows the oil heater to be precisely installed at a specific position in the oil tank cavity, providing a stable physical basis for heating the lubricating oil.

[0023] The baffle plate is one of the key innovations of this technical solution. It divides the oil tank cavity into a first chamber and a second chamber, with the first chamber and the first fixed mounting flange located on the same side of the baffle plate. This division means that the oil heater is installed in the first chamber, and the oil inlet pipe is also connected to the first chamber. In low-temperature environments, the oil heater can quickly heat the lubricating oil in the first chamber to the required start-up temperature. Because the first chamber is relatively independent, the heating efficiency is significantly improved, ensuring that the compressor can start rapidly under low-temperature conditions.

[0024] Furthermore, the baffle plate's separation function significantly improves transportation safety. Firstly, the fuel tank is divided into two chambers, with lubricating oil stored separately in each. This separate storage method effectively mitigates the sloshing energy of the lubricating oil during vehicle bumps or sudden braking. When bumps or sudden braking occur during vehicle operation, the sloshing of the lubricating oil is confined to its respective chamber, reducing significant sloshing within the fuel tank and thus lowering the safety risks that may arise from violent lubricating oil movement.

[0025] On the other hand, the baffle plate itself also absorbs the energy from shaking. Its structural design allows it to absorb some energy when the lubricating oil sloshes, further stabilizing its storage state. This design not only protects the internal structure of the oil tank from the impact of violent shaking of the lubricating oil, but also ensures the stability of the lubricating oil during transportation, improving the overall transportation safety of the oil tank.

[0026] Based on the above structural and process descriptions, it can be seen that the oil tank for the compressor has at least the following beneficial effects: By dividing the oil tank cavity into two chambers and installing the oil heater in the first chamber connected to the oil inlet pipe, the oil can be quickly heated to the start-up temperature in a low-temperature environment. At the same time, by utilizing the separating ability of the baffle plate, the shaking energy is dissipated through separate storage in multiple locations, which effectively improves the heating efficiency and transportation safety of the oil tank.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figures 1 to 4 ,in, Figure 1 This is a structural diagram of the oil tank for a compressor provided in an embodiment of this application. Figure 2 for Figure 1 Internal structure diagram of the fuel tank. Figure 3 for Figure 2 A schematic diagram of the fuel tank from another perspective. Figure 4 for Figure 1 Installation diagram of the intermediate fuel tank.

[0042] In a first specific embodiment, the oil tank 100 for a compressor provided in this application mainly includes an oil tank body 1, a baffle plate 2, an oil inlet pipe 3, and an oil return pipe 4. The oil tank body 1 has an oil tank cavity 11, and a first fixed mounting flange is provided on the cavity wall. This flange is specifically used to install an oil heater. This design allows the oil heater to be precisely installed at a specific position in the oil tank cavity 11, providing a stable physical basis for heating the lubricating oil.

[0043] The design of the baffle plate 2 is one of the key innovations of this technical solution. The baffle plate 2 divides the oil tank cavity 11 into a first chamber 111 and a second chamber 112, with the first chamber 111 and the first fixed mounting flange located on the same side of the baffle plate 2. This division means that the oil heater is installed in the first chamber 111, and the oil inlet pipe 3 is also connected to the first chamber 111. In low-temperature environments, the oil heater can quickly heat the lubricating oil in the first chamber 111 to the required start-up temperature. Because the first chamber 111 is relatively independent, the heating efficiency is significantly improved, ensuring that the compressor can start rapidly under low-temperature conditions.

[0044] Furthermore, the separation function of the baffle plate 2 significantly improves transportation safety. Firstly, the oil tank cavity 11 is divided into two chambers, with lubricating oil stored separately in each. This separate storage method effectively mitigates the sloshing energy of the lubricating oil during vehicle bumps or sudden braking. When bumps or sudden braking occur during vehicle operation, the sloshing of the lubricating oil is confined to its respective chamber, reducing significant sloshing within the oil tank 100 and thus lowering the safety risks that may arise from violent lubricating oil sloshing.

[0045] On the other hand, the baffle plate 2 also absorbs the energy from shaking. The structural design of the baffle plate 2 allows it to absorb some energy when the lubricating oil shakes, further stabilizing the storage state of the lubricating oil. This design not only protects the internal structure of the oil tank 100 from the impact of violent shaking of the lubricating oil, but also ensures the stability of the lubricating oil during transportation, improving the overall transportation safety of the oil tank 100.

[0046] Based on the above structural and process descriptions, it can be seen that the oil tank 100 for the compressor has at least the following beneficial effects: By dividing the oil tank cavity 11 into two chambers and installing the oil heater in the first chamber 111 connected to the oil inlet pipe 3, the oil tank 100 for the compressor can quickly heat the oil to the start-up temperature in a low-temperature environment. At the same time, by utilizing the separating ability of the liquid baffle 2, the shaking energy is dissipated through separate storage in multiple locations, which effectively improves the heating efficiency and transportation safety of the oil tank 100.

[0047] In some embodiments, the liquid separator 2 is provided with an interception structure 21, which is used to block the foam generated by the return oil from flowing from the second chamber 112 to the first chamber 111.

[0048] In this embodiment, the baffle plate 2 is provided with an interception structure 21. This interception structure 21 can effectively prevent impurities such as foam, oil film, and oil mist generated in the second chamber 112 during the oil return process from flowing into the first chamber 111. When the compressor is running, the lubricating oil returns to the second chamber 112 of the oil tank 100 through the oil return pipe 4. During this process, impurities such as foam, oil film, or oil mist may be generated due to flow and air action. If these impurities enter the first chamber 111 without being blocked, they may adversely affect the normal operation of the oil heater and the cleanliness of the lubricating oil, thereby affecting the performance and service life of the compressor.

[0049] The interception structure 21, through its specific structural design, prevents impurities from flowing from the second chamber 112 into the first chamber 111. As a critical area for lubricating oil heating and delivery, the cleanliness of the internal environment of the first chamber 111 is essential for ensuring the heating efficiency of the lubricating oil and the normal operation of the compressor. By setting up the interception structure 21, the lubricating oil in the first chamber 111 can remain relatively clean, reducing interference from impurities to the oil heater, improving the heating efficiency of the lubricating oil and the overall performance of the compressor. Furthermore, this design extends the service life of the oil heater and reduces maintenance costs.

[0050] In some embodiments, the interception structure 21 is located at the top of the liquid separator 2, and the interception structure 21 is bent from the first chamber 111 toward the second chamber 112.

[0051] In this embodiment, the interception structure 21 is specifically disposed at the top of the liquid-separating plate 2, and the interception structure 21 bends from the first chamber 111 toward the second chamber 112. This bendable interception structure 21 is actually a bent body 25 at the top of the liquid-separating plate 2. This specific shape and position design of the bent body 25 enables it to effectively block impurities such as foam, oil film, and oil mist flowing from the second chamber 112 to the first chamber 111.

[0052] The design of the bent body 25 not only increases the surface area of ​​the interception structure 21, but also forms a physical barrier through its bending direction. When impurities such as foam, oil film, or oil mist generated during the oil return process attempt to flow from the second chamber 112 to the first chamber 111, the bent body 25 can effectively prevent the flow of these impurities. Since these impurities usually float on the liquid surface, the height and bending direction of the bent body 25 can ensure that these impurities will not easily cross the liquid separator 2 and enter the first chamber 111.

[0053] This design ensures the cleanliness and stability of the lubricating oil within the first chamber 111 while maintaining its flow. As a critical area for lubricating oil heating and delivery, the cleanliness of the internal environment of the first chamber 111 is essential for ensuring the heating efficiency of the lubricating oil and the normal operation of the compressor. By incorporating the bent body 25 as an interception structure 21, interference from impurities to the oil heater can be effectively reduced, thereby improving the heating efficiency of the lubricating oil and the overall performance of the compressor.

[0054] In some embodiments, the liquid separator 2 is provided with a grid structure 22, which connects the first chamber 111 and the second chamber 112.

[0055] In this embodiment, a grid structure 22 is provided on the liquid separator 2, which serves to connect the first chamber 111 and the second chamber 112. The design of the grid structure 22 allows lubricating oil to flow between the two chambers, thereby achieving uniform distribution of lubricating oil throughout the oil tank 100. This flow is crucial for ensuring the heating efficiency of the lubricating oil and the normal operation of the compressor.

[0056] The specific design of the grid structure 22 includes multiple grid plates 24, which are spaced apart along the length of the plate body 23 to form a grid structure 22 with specific channels. This structure not only allows lubricating oil to flow between the two chambers, but also allows control over the flow speed and direction. Through these channels, heated lubricating oil can flow from the first chamber 111 to the second chamber 112, ensuring a more uniform lubricating oil temperature throughout the oil tank.

[0057] It is important to note that impurities such as foam, oil film, or oil mist typically float on the liquid surface, which is usually higher than the grid structure 22. Therefore, these impurities will not enter the first chamber 111 through the grid structure 22. Instead, the interception structure 21, located at the top of the liquid baffle 2 and level with the liquid surface, effectively blocks these floating impurities, preventing them from flowing from the second chamber 112 to the first chamber 111. This design of the interception structure 21 ensures the cleanliness of the lubricating oil in the first chamber 111, thus guaranteeing the normal operation of the oil heater and the efficient heating of the lubricating oil.

[0058] In some embodiments, the liquid separator 2 is provided with a plate body 23, and a plurality of grid plates 24 are provided at the upper end of the plate body 23. The plurality of grid plates 24 are spaced apart in the length direction of the plate body 23, and the plurality of grid plates 24 constitute a grid structure 22.

[0059] In this embodiment, the liquid separator 2 includes a plate body 23 located inside the oil tank cavity 11, serving to separate the first chamber 111 and the second chamber 112. The upper end of the plate body 23 is provided with multiple grid plates 24, which are spaced apart along the length of the plate body 23, collectively forming a grid structure 22. This structural design has multiple functions.

[0060] Plate 23, as the bottom layer of the baffle plate 2, is positioned and positioned at a height that effectively prevents sediment from the bottom of the second chamber 112 from entering the first chamber 111. Since sediment typically settles at the bottom of the oil tank cavity 11, the presence of plate 23 prevents this sediment from entering the first chamber 111 through the bottom of the baffle plate 2, thus maintaining the cleanliness of the lubricating oil in the first chamber 111. This is crucial for the normal operation of the oil heater and the heating efficiency of the lubricating oil.

[0061] Meanwhile, the configuration of the grille structure 22 is also significant. Multiple grille plates 24 extend upwards, leaving gaps between them, forming a grille structure 22 with specific channels. This structure not only allows lubricating oil to flow between the two chambers but also controls the direction and speed of the flow. Through these gaps, heated lubricating oil can flow from the first chamber 111 to the second chamber 112, while preventing impurities in the second chamber 112 from entering the first chamber 111 through these gaps. This design ensures the flow of lubricating oil while also improving the stability and cleanliness of the internal environment of the oil tank 100.

[0062] In some embodiments, the top end of the grid plate 24 is provided with a bending body 25, which is bent from the first chamber 111 toward the second chamber 112.

[0063] In this embodiment, each grid plate 24 of the liquid separator 2 is provided with a bent body 25 at its top end. These bent bodies 25 are bent from the first chamber 111 toward the second chamber 112. This combination of grid plate 24 and bent body 25 not only increases the structural stability of the liquid separator 2, but also further enhances the ability to intercept impurities such as foam, oil film and oil mist generated during the oil return process.

[0064] The bending shape and direction of the bent body 25 create an additional physical barrier at the top of the grid plate 24. When the lubricating oil flows back to the second chamber 112 through the return oil pipe 4, impurities such as foam, oil film, and oil mist usually float on the liquid surface. The bent body 25 can prevent these impurities from flowing into the first chamber 111 with the liquid. The significance of this design is that it utilizes the buoyancy and flow characteristics of impurities such as foam, and reduces the migration of impurities from the second chamber 112 to the first chamber 111 through the blocking effect of the bent body 25.

[0065] Furthermore, this design not only improves the separation effect of the oil tank 100, but also ensures the cleanliness and stability of the lubricating oil in the first chamber 111. As a key area for lubricating oil heating and delivery, the cleanliness of the internal environment of the first chamber 111 is crucial for ensuring the heating efficiency of the lubricating oil and the normal operation of the compressor. By setting a bent body 25 at the top of the grid plate 24, interference from impurities to the oil heater can be effectively reduced, improving the heating efficiency of the lubricating oil and the overall performance of the compressor.

[0066] In some embodiments, the oil tank 100 further includes an oil mist filter device disposed in the second chamber 112.

[0067] In this embodiment, the oil tank 100 further includes an oil mist filter device disposed within the second chamber 112. The main function of this device is to filter impurities such as oil mist and foam generated during the oil return process, ensuring the cleanliness of the lubricating oil and the stability of the internal environment of the oil tank. The oil mist filter device effectively intercepts and filters these impurities through its filter medium, such as an optional filter screen. The filter screen is designed so that oil mist and foam in the lubricating oil are captured and separated as they pass through, thereby maintaining the cleanliness of the lubricating oil.

[0068] In some embodiments, the height of the bottom end of the oil inlet pipe 3 is lower than the height of the bottom end of the oil return pipe 4.

[0069] In this embodiment, the bottom height of the oil inlet pipe 3 is designed to be lower than the bottom height of the oil return pipe 4. This design takes into account the functional differences between the oil inlet pipe 3 and the oil return pipe 4. The main function of the oil inlet pipe 3 is to draw lubricating oil from the oil tank cavity 11 and supply it to other components of the compressor, while the oil return pipe 4 returns the used lubricating oil to the oil tank cavity 11.

[0070] Because the bottom of the oil inlet pipe 3 is positioned low, it can more effectively draw lubricating oil from the bottom of the oil tank cavity 11, ensuring a continuous and stable oil supply even when the oil tank level is low. This design helps improve the reliability of oil supply to the oil tank 100 under different liquid level conditions. In particular, when the oil tank level is low, the oil inlet pipe 3 can still contact the lubricating oil, preventing compressor operation interruption due to insufficient oil supply.

[0071] On the other hand, the higher position of the bottom end of the return oil pipe 4 helps reduce lubricating oil splashing and foam generation during the return oil process. When the lubricating oil flows back to the oil tank cavity 11 through the return oil pipe 4, the higher position of the bottom end of the return oil pipe 4 reduces the direct impact of the return oil on the bottom of the oil tank, thereby reducing liquid level fluctuations and foam generation caused by the return oil. This design not only improves the stability of the internal environment of the oil tank, but also reduces potential problems caused by foam and liquid level fluctuations, such as excessive oil mist and increased oil temperature.

[0072] In some embodiments, the cavity wall of the oil tank cavity 11 is further provided with a second fixed mounting flange, which is used to install an auxiliary oil pump.

[0073] In this embodiment, a second fixed mounting flange is specially provided on the cavity wall of the oil tank 11. The purpose of this design is to install an auxiliary oil pump, thereby enhancing the functionality and flexibility of the oil tank 100.

[0074] The installation of the auxiliary oil pump is crucial for the operation of the oil tank 100. Under certain operating conditions, such as when the main oil pump fails or when additional lubricating oil supply is required, the auxiliary oil pump can provide necessary support to ensure a continuous supply of lubricating oil. By providing a second fixed mounting flange on the cavity wall of the oil tank 11, the auxiliary oil pump can be easily installed and secured, enabling it to work in conjunction with other components of the oil tank 100.

[0075] This design not only improves the reliability of the oil tank 100 but also enhances its adaptability to different operating conditions. The auxiliary oil pump is precisely fixed in place by the second fixed mounting flange, ensuring stable operation during use and preventing loosening due to vibration or other external forces. Furthermore, this design facilitates the installation and maintenance of the auxiliary oil pump, improving the overall maintenance efficiency of the oil tank 100.

[0076] In some embodiments, the fuel tank body 1 includes a tank body 12 and a cover plate 13. The cover plate 13 is located at the top of the tank body 12 and is detachably connected to the tank body 12. The oil inlet pipe 3 and the oil return pipe 4 are integrated into the cover plate 13.

[0077] In this embodiment, the fuel tank body 1 consists of a tank body 12 and a cover plate 13. The cover plate 13 is located at the top of the tank body 12 and is detachably connected to the tank body 12. This design makes the assembly and maintenance of the fuel tank body 1 more convenient. In particular, the oil inlet pipe 3 and the oil return pipe 4 are integrated on the cover plate 13, and this integrated design significantly simplifies the installation process of the fuel tank 100.

[0078] Since the inlet pipe 3 and return pipe 4 are integrated into the cover plate 13, the entire cover plate 13 can be directly installed onto the tank body 12 as a single component during installation. This integration method not only reduces installation steps but also improves installation efficiency and accuracy. In practice, technicians can first assemble and test the cover plate 13 with the inlet pipe 3 and return pipe 4 as a whole to ensure that the connections between the components are correct. Subsequently, this pre-assembled component is installed onto the tank body 12 and fixed using a detachable connection, thereby completing the assembly of the tank body 1.

[0079] Another advantage of this design is its ease of maintenance. When maintenance or replacement of the inlet pipe 3 or return pipe 4 is required, these components can be easily accessed simply by removing the cover plate 13, without the need for complex disassembly of the entire fuel tank body 1. This modular design not only improves the assembly and maintenance efficiency of the fuel tank 100, but also reduces potential risks caused by improper installation or maintenance difficulties.

[0080] In one specific embodiment, the liquid separator 2 is installed by welding or by fasteners.

[0081] For the installation of the fuel tank 100, the fuel tank body 1 is fixed to the base by fasteners 5, which facilitates disassembly and installation, and the top cover 13 can be removed to ensure convenient cleaning later.
