Description
Technical Field
[0001] This invention belongs to the technical field of submersible mixers, and in particular relates to a hydraulic oil cooling module for submersible mixers. Background Technology
[0002] The hydraulic station of the hydraulic transmission submersible thruster works continuously outdoors in harsh conditions. The temperature of the hydraulic oil in the tank is greatly affected by environmental factors, and the temperature fluctuation range is also large. If the temperature of the hydraulic oil in the tank cannot be controlled within a suitable range, the oil temperature will be too high, which will accelerate the aging of hydraulic components and reduce their service life.
[0003] Currently, liquid cooling is a relatively efficient and common method, but its disadvantages are also obvious. Since it usually requires the use of existing fixed components to form cooling pipelines, the cooling area is limited, and the heat dissipation cannot be evenly distributed due to different locations. Therefore, the cooling efficiency is difficult to keep up. For long-term high-temperature and high-pressure operation, the existing cooling methods are inadequate.
[0004] To address these issues, we propose a hydraulic oil cooling module for submersible mixers. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned problems by providing a submersible mixer hydraulic oil cooling module that can output corresponding cooling power by matching the rotation speed of the submersible mixer.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a submersible mixer hydraulic oil cooling module, comprising a submersible mixer body, a pipeline assembly pipe, and a fixing plate. The fixing plate is fixedly connected to the bottom of the pipeline assembly pipe, and the submersible mixer body is mounted on the fixing plate. The submersible mixer body and the pipeline assembly pipe are provided with the same outer shell pipe on one side. The outer shell pipe is bent, with one end connected to the submersible mixer body and the other end connected to the pipeline assembly pipe. A hydraulic oil submersible pipe is provided inside the outer shell pipe. The hydraulic oil submersible pipe is connected to the pipeline assembly pipe and the hydraulic oil pipeline inside the submersible mixer body. A gear ring is fixedly sleeved on the rotating head of the submersible mixer body. A rotating shaft is provided outside the submersible mixer body. A gear that meshes with the gear ring is provided at the end of the rotating shaft. A cooling device is provided on the outer shell pipe. One end of the rotating shaft is synchronously connected to the cooling device and the hydraulic oil submersible pipe.
[0007] In the aforementioned submersible mixer hydraulic oil cooling module, the hydraulic oil underwater pipe is fixed inside the outer casing and is arranged in a meandering manner.
[0008] In the aforementioned submersible mixer hydraulic oil cooling module, the cooling device includes a conveyor chain link, multiple limiting rollers, a main drive roller, and multiple auxiliary drive rollers. The outer casing tube has openings at both its beginning and end, symmetrically arranged. The conveyor chain link is located inside the outer casing tube. The multiple limiting rollers are rotatably connected to the outer casing tube and limit the movement of the conveyor chain link. The main drive roller and multiple auxiliary drive rollers mesh with the beginning and end of the conveyor chain link, respectively. Multiple impeller assemblies are located within the openings. The impeller assemblies are rotatably connected to the inner wall of the outer casing tube and coaxially fixedly connected to the multiple auxiliary drive rollers. The main drive roller is coaxially fixedly connected to the rotating shaft.
[0009] In the aforementioned submersible mixer hydraulic oil cooling module, the blade curvature surfaces of the two symmetrically symmetrically positioned impeller groups are opposite, and the shafts of the two impeller groups are coaxially fixedly connected.
[0010] In the aforementioned submersible mixer hydraulic oil cooling module, one end of the rotating shaft extends into the hydraulic oil submersible pipe and is fixedly connected to a drive wheel.
[0011] In the aforementioned submersible mixer hydraulic oil cooling module, the outer shell tube is in the shape of a flat plate, and multiple sludge guide ports are provided on the side wall of the outer shell tube. A filter screen plate is inclinedly provided inside the sludge guide ports.
[0012] In the aforementioned submersible mixer hydraulic oil cooling module, one end of the filter screen is rotatably connected to the inner wall of the outer casing tube, and a spring is fixedly connected to the end of the filter screen away from the drain port. One end of the spring is fixedly connected to the inner wall of the outer casing tube.
[0013] In the aforementioned submersible mixer hydraulic oil cooling module, the outer casing tube is provided with multiple compartments, which are mutually sealed. The hydraulic oil underwater pipe is arranged through the multiple compartments. The drain outlet and the opening are respectively located at the beginning and end of the compartment. The conveyor chain link is arranged through the compartment and meshes with the auxiliary drive roller on the impeller assembly in each opening.
[0014] In the aforementioned submersible mixer hydraulic oil cooling module, the drain outlets and openings between adjacent compartments are far apart from each other.
[0015] In the aforementioned submersible mixer hydraulic oil cooling module, the shafts of the impeller assemblies within the symmetrical compartments on the outer casing tube are coaxially and fixedly connected.
[0016] Compared with existing technologies, the advantages of this submersible mixer hydraulic oil cooling module are:
[0017] 1. This invention utilizes the combination of an outer casing tube, a transmission chain link, a gear ring, gears, and an impeller assembly to replace the traditional cooling pipeline integrated with a fixed support by using an external outer casing tube. At the same time, the gear ring, gears, and transmission chain link transmit the rotational speed of the submersible mixer to the impeller assembly inside the outer casing tube in real time, thereby achieving the output of corresponding cooling power to match the rotational speed of the submersible mixer.
[0018] 2. This invention utilizes the combination of a drain outlet, a filter plate, a spring, and a partition to separate some of the water from the waste entering the outer casing tube and discharge it to the outside, preventing it from accumulating inside the outer casing tube and affecting normal cooling operations. Finally, the partition enhances the drainage capacity of each section, thereby better ensuring the cooling effect within the partition. Attached Figure Description

Detailed Implementation
[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0031] Example 1
[0032] The hydraulic station of the "hydraulic transmission type submersible thruster" works continuously in an outdoor environment for a long time. The working environment is harsh, and the temperature of the hydraulic oil in the oil tank is greatly affected by environmental factors, with a large range of oil temperature fluctuations. If the temperature of the hydraulic oil in the hydraulic tank cannot be controlled within a suitable range, the oil temperature will be too high, which will accelerate the aging of hydraulic components and reduce their service life.
[0033] Currently, liquid cooling is a relatively efficient and common method, but its disadvantages are also obvious. Because it typically requires existing fixed components to form cooling pipes, the cooling area is limited, and the uneven heat dissipation due to varying locations makes it difficult to maintain cooling efficiency. Under long-term high-temperature and high-pressure operation, existing cooling methods become inadequate. Therefore, if… Figure 1 As shown, this solution designs a hydraulic oil cooling module for a submersible mixer. The main body includes a submersible mixer body 1, a pipeline assembly pipe 2, and a fixing plate 3. The submersible mixer body 1, pipeline assembly pipe 2, and fixing plate 3 are all existing components. The pipeline assembly pipe 2 is responsible for fixing and also for laying, installing, and fixing multiple pipelines. The fixing plate 3 is fixedly connected to the bottom of the pipeline assembly pipe 2 for support. The submersible mixer body 1 is installed on the fixing plate 3 for fixing and use.
[0034] like Figure 1-2 As shown, the submersible mixer body 1 and pipeline assembly pipe 2 are provided with the same outer shell pipe 4 on one side. The outer shell pipe 4 is hollow and connected to the outside of the submersible mixer body 1 and pipeline assembly pipe 2. In order to form an oil return flow, the outer shell pipe 4 is bent, with one end connected to the submersible mixer body 1 and the other end connected to the pipeline assembly pipe 2. A hydraulic oil submersible pipe 5 is provided inside the outer shell pipe 4. The purpose of the hydraulic oil submersible pipe 5 is to transport the oil inside the submersible mixer body 1 to the outside for cooling and then return it to the pipeline assembly pipe 2. The hydraulic oil submersible pipe 5 is connected to the pipeline assembly pipe 2 and the hydraulic oil pipeline inside the submersible mixer body 1 to form a stable return flow loop.
[0035] In order to provide a larger heat dissipation area for the hydraulic oil submersible pipe 5, the hydraulic oil submersible pipe 5 is fixed inside the outer casing pipe 4 and is arranged in a meandering shape. The problem with traditional liquid cooling is that the upper limit of heat dissipation often cannot completely cover the oil envelope requirements, resulting in insufficient heat dissipation under extreme conditions. In order to meet the real-time heat dissipation requirements,
[0036] Therefore, as Figure 3-5 As shown, a gear ring 6 is fixedly sleeved on the outside of the rotating head of the submersible mixer body 1. The gear ring 6 rotates synchronously with the rotating head of the submersible mixer body 1. A rotating shaft 7 is provided outside the submersible mixer body 1. In order to fix the rotating shaft 7, a fixing bracket or the like can be installed on the side wall of the submersible mixer body 1 to maintain stability. The end of the rotating shaft 7 is provided with a gear 19 that meshes with the gear ring 6. Therefore, under the connection of the rotating shaft 7, the rotation of the gear ring 6 will drive the gear 19 to rotate synchronously.
[0037] In addition, a cooling device is provided on the outer shell tube 4. The cooling device includes a conveyor chain link 8, multiple limiting rollers 9, a main drive roller 10, and multiple auxiliary drive rollers 11. Openings 12 are provided at both the beginning and end of the outer shell tube 4. The two openings 12 are symmetrically arranged. The conveyor chain link 8 is located inside the outer shell tube 4. Since the conveyor chain link 8 meshes with the gear 19, the gear 19 can drive the conveyor chain link 8 to rotate actively. The multiple limiting rollers 9 are rotatably connected to the outer shell tube 4 and limit the movement of the conveyor chain link 8, so that the conveyor chain link 8 is always rotating stably and will not derail. The position of the limiting rollers 9 can be arranged according to actual needs, and all of them can be rotatably connected to the outer shell tube 4.
[0038] Therefore, as Figure 6As shown, the main drive roller 10 and multiple auxiliary drive rollers 11 are respectively engaged with the beginning and end of the transmission chain 8 for transmission connection. Multiple impeller groups 13 are provided within the opening 12, so the main drive roller 10 can synchronously drive the impeller groups 13 to rotate via the transmission chain 8. In the design, the blade curvature surfaces of the impeller groups 13 within the two symmetrical openings 12 are opposite, and the shafts of the two impeller groups 13 are coaxially fixedly connected. Therefore, the multiple impeller groups 13 always rotate synchronously and in opposite directions, one for suction and one for discharge, thus forming a stable circulating fluid within the outer casing 4 for cooling the hydraulic oil submersible pipe 5. The impeller groups 13 are rotatably connected to the inner wall of the outer casing 4 for fixation and are coaxially fixedly connected to the multiple auxiliary drive rollers 11. The main drive roller 10 is coaxially fixedly connected to the rotating shaft 7. One end of the rotating shaft 7 is synchronously connected to the cooling device and the hydraulic oil submersible pipe 5. One end of the rotating shaft 7 extends into the hydraulic oil submersible pipe 5 and is fixedly connected to the drive wheel 14. The drive wheel 14 synchronously drives the flow (or accelerates) of the oil, so that the flow rate is matched and adjusted according to the cooling speed. There are many ways to design the drive wheel 14, which are existing technologies and will not be listed here. Through the cooperation of the outer shell pipe 4, the transmission chain link 8, the gear ring 6, the gear 19, and the impeller assembly 13, the external outer shell pipe 4 is used to replace the traditional cooling pipeline integrated with the fixed bracket. At the same time, the rotation speed of the submersible mixer is transmitted to the impeller assembly 13 in the outer shell pipe 4 in real time through the gear ring 6, the gear 19, and the transmission chain 8, so as to achieve the output of corresponding cooling power to match the rotation speed of the submersible mixer.
[0039] Example 2
[0040] Because the water environment used is usually sewage, which contains a lot of impurities, it was found in the implementation of Example 1 that although water can pass through the long outer shell tube 4 during the circulation process, some sediment will accumulate inside. Although most of the sediment can be carried away by the circulating water, some will still accumulate and adhere, resulting in a gradual decrease in cooling efficiency after long-term use.
[0041] Therefore, as Figure 7As shown, in this embodiment, the outer shell tube 4 is a flat plate, and multiple drainage ports 15 are provided on the side wall of the outer shell tube 4. For effective fixation, the outer shell tube 4 can be directly fixed to the bottom of the pool or fixed using an external bracket. A filter screen plate 16 is inclinedly installed inside the drainage ports 15. One end of the filter screen plate 16 is rotatably connected to the inner wall of the outer shell tube 4. The inclination direction of the filter screen plate 16 matches the flow direction of the water. A spring 17 is fixedly connected to the end of the filter screen plate 16 facing away from the drainage ports 15. One end of the spring 17 is fixedly connected to the inner wall of the outer shell tube 4. Due to the presence of the filter screen plate 16... This allows wastewater to flow directly through the filter screen 16 after entering, while sediment is guided out by the filter screen 16, reducing its residence time in the outer casing pipe 4 and thus reducing sediment accumulation inside the pipe. In the case of excessive clogging of the filter screen 16, the excessive force on the filter screen 16 causes the spring 17 to be compressed. Finally, the filter screen 16 is vibrated and cleaned by opening and closing, while not obstructing the normal flow of water locally. To further improve the efficiency of the spring 17, a protective paint layer is applied to the outside of the spring 17.
[0042] Example 3
[0043] In some parts of the outer casing tube 4, due to its length, the circulating fluid takes a considerable amount of time to pass through the outer casing tube 4, thus failing to achieve a high cooling effect. Figure 8-9 As shown, the outer casing tube 4 is provided with multiple compartments 18, which are mutually sealed and divide the outer casing tube 4 into multiple regions. Each region has a circulation system. The hydraulic oil and water pipes 5 pass through the multiple compartments 18 for normal reflux operations. To reduce the impact of suction and discharge between the guide port 15 and the opening 12, the guide port 15 and the opening 12 are respectively located at the beginning and end of the compartment 18, maintaining a certain distance to prevent discharged sediment from re-entering the opening 12. The shafts of the impeller assemblies 13 in the symmetrical compartments 18 on the outer casing tube 4 are coaxially fixed. The fixed connection, the conveyor chain link 8 passes through the compartment 18, and is connected by the same conveyor chain link 8. It also meshes with the auxiliary drive roller 11 on the impeller assembly 13 in each opening 12. The gap left by the conveyor chain link 8 and the hydraulic oil and water pipe 5 is negligible and does not affect the normal flow. The filter screen plate 16 in the sewage guide port 15 can be used to separate the garbage entering the outer casing pipe 4 and discharge a part of the water to the outside, so as to prevent the accumulation inside the outer casing pipe 4 from affecting the normal cooling operation. Finally, the compartment 18 is used to improve the sewage discharge capacity of each section, thereby better ensuring the cooling effect in the compartment 18.
[0044] Although this document frequently uses terms such as submersible mixer body 1, pipeline assembly pipe 2, fixing plate 3, outer casing pipe 4, hydraulic oil submersible pipe 5, gear ring 6, rotating shaft 7, transmission chain link 8, limiting roller 9, main drive roller 10, auxiliary drive roller 11, opening 12, impeller assembly 13, drive wheel 14, drain outlet 15, filter screen plate 16, spring 17, compartment 18, gear 19, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
