Description

Technical Field

[0001] The utility model relates to the field of hydraulic components, in particular to an integrated device for oil replenishment and air exhaust of a hydraulic station oil tank. Background Technique

[0002] The hydraulic oil tanks used in the main machine, platform and vibration hydraulic system of a slab caster are all equipped with air filters. It is vertically installed on the oil tank cover. When the hydraulic system works, the oil level in the oil tank sometimes rises or sometimes falls. When it rises, air is discharged from the inside to the outside, and when it falls, air is inhaled from the outside to the inside. At the same time, the air filter is also an oil filling port. When injecting new working oil, it must pass through filtration and then enter the oil tank, thereby filtering out larger particles of impurities in the oil.

[0003] However, in actual use, there are still the following deficiencies. For example, when on-site maintenance personnel replenish new working oil, they put the fueling hose into the air filter for fueling. At this time, the fueling hose and the filter element are in direct contact with the external environment, and dust and impurities in the work are likely to enter the oil, resulting in oil pollution; secondly, during the fueling process, if the oil flow rate in the fueling hose is too fast, the filter element filtration is likely to cause oil spillage; there is a certain height difference between the filter element and the liquid level in the oil tank. During the fueling process, the oil drops into the oil tank, and the huge height difference is likely to cause a large amount of air bubbles to mix into the oil. When the hydraulic system operates, the oil pump is prone to cavitation, reducing the service life of the oil pump, and at the same time affecting the control accuracy of the hydraulic valve, which becomes one of the main factors affecting the stable operation of the hydraulic system.

[0004] Therefore, the utility model provides an integrated device for oil replenishment and air exhaust of a hydraulic station oil tank. Content of the Utility Model

An opening is provided on the outer side of the guiding pipe. A joint is arranged at the opening, and a dust-proof cap is sleeved on the outer side of the joint.

[0009] The technical effects of adopting the above technical solution are as follows: The integration of the oil replenishment and exhaust functions is realized, thereby simplifying the structure of the hydraulic station oil tank and reducing the complexity of on-site installation and maintenance.

[0010] As a preferred embodiment, the circulation port is in the shape of a 45-degree inclined opening.

[0011] The technical effects of adopting the above technical solution are as follows: When replenishing oil, the oil can flow into the oil tank in a smoother manner, reducing the bubbles generated by the falling of the oil, thereby improving the stability of the hydraulic system and the service life of the oil pump.

[0012] As a preferred embodiment, the end of the guiding pipe far from the conducting body is fixedly connected to the second connecting ring.

[0013] The technical effects of adopting the above technical solution are as follows: The connection between the guiding pipe and the conducting body is made more stable, ensuring that the guiding pipe will not be displaced or detached during the oil replenishment and exhaust processes.

[0014] As a preferred embodiment, one end of the dust cap close to the joint is in contact with the guiding pipe.

[0015] The technical effects of adopting the above technical solution are as follows: Effectively prevent dust and impurities from entering the inside of the guiding pipe through the joint, ensuring the cleanliness of the oil during the oil replenishment and exhaust processes.

[0016] As a preferred embodiment, the dust cap is made of polyurethane material.

[0017] The technical effects of adopting the above technical solution are as follows: It can still maintain a good protection effect in high-temperature or low-temperature environments, ensuring the reliability of the device in different working environments.

[0018] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0019] By setting the structure of the conducting component and the guiding component, the present utility model first installs an air filter above the conducting body.

A fueling hose joint is welded on the conducting body, facilitating the fueling operation and the stable inflow of oil. When not refueling, a dust cap can be installed to prevent pollution. Such a design not only effectively solves the problems of slow oil replenishment in the hydraulic station oil tank and easy mixing of air during the oil replenishment process, but also prevents particulate pollutants from invading the system through the breather of the oil tank and causing oil pollution. Secondly, the device is simple to manufacture, has a low processing cost, and has strong on-site practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figure 1 - Figure 2 shown, this embodiment provides a technical solution: an integrated device for oil replenishment and exhaust of a hydraulic station fuel tank, including a conduction assembly 1, and a guiding assembly 2 is fixedly connected to the top of the conduction assembly 1;

[0028] The conduction and ventilation component 1 includes a conduction body 11 and a second connecting ring 14. A circulation port 12 is provided at the bottom end of the conduction body 11. The circulation port 12 is in the shape of an inclined opening at a 45-degree angle. One end of the conduction body 11 away from the circulation port 12 is fixedly connected to a first connecting ring 13. An air filter 15 is installed at one end of the second connecting ring 14 away from the conduction body 11. The conduction and ventilation component 1 is the core part of the whole device, responsible for integrating the functions of oil replenishment and exhaust in one device. It consists of the conduction body 11 and the second connecting ring 14. The circulation port 12 is provided at the bottom end of the conduction body 11 and is designed as an inclined opening at 45 degrees. The purpose of this design is to introduce the replenished oil into the fuel tank in a more stable manner, avoid the direct drop of the oil, reduce the possibility of generating bubbles, and thus protect the stability of the hydraulic device. The 45-degree inclined opening design of the circulation port 12 enables the oil to flow smoothly into the fuel tank below the liquid level, effectively preventing the bubbles generated by the liquid level drop from entering the oil. This can reduce the cavitation phenomenon generated during the operation of the oil pump, thereby extending the service life of the oil pump and improving the operation stability of the hydraulic device. The distal end of the conduction body 11 is fixedly connected to a first connecting ring 13. The first connecting ring 13 ensures the firm connection between the conduction body 11 and other parts of the device. The second connecting ring 14 is installed at one end of the conduction body 11 away from the circulation port 12 and is connected to the air filter 15. The function of the second connecting ring 14 is to ensure the tight connection between the air filter 15 and the conduction body 11, ensure that the air filter 15 can still effectively filter the impurities in the air during the oil replenishment process, and prevent pollutants from entering the oil. The air filter 15 is installed at the top of the conduction and ventilation component 1 and is connected to the conduction body 11 through the second connecting ring 14. When the hydraulic device is working, the air filter 15 can perform air exchange between the inside and outside of the fuel tank, and effectively filter the dust and impurities in the air during the oil replenishment process to prevent these pollutants from entering the oil;

[0029] Furthermore, as Figure 1 With Figure 3As shown: In this solution, the guiding component 2 includes a guiding pipe 21. One end of the guiding pipe 21 away from the conducting body 11 is fixedly connected to the second connecting ring 14, and one end of the guiding pipe 21 is fixedly connected to the conducting body 11. Openings 22 are provided on the outer side of the guiding pipe 21, and connectors 23 are arranged at the openings 22. A dust-proof cap 24 is sleeved on the outer side of the connector 23. The dust-proof cap 24 is made of polyurethane. One end of the dust-proof cap 24 close to the connector 23 is in contact with the guiding pipe 21. The guiding pipe 21 plays a role in guiding the flow of the oil fluid. Its design is to ensure that the oil fluid can enter the fuel tank through a relatively closed channel during the replenishment process, thereby reducing the risk of pollutants in the external environment entering the oil fluid. One end of the guiding pipe 21 is fixedly connected to the conducting body 11, which can ensure the continuity and stability of the entire oil fluid flow path. Openings 22 are provided on the outer side of the guiding pipe 21, and connectors 23 are arranged at the openings 22. The arrangements of the openings 22 and the connectors 23 provide an external interface for the system, facilitating the connection of other auxiliary devices or maintenance operations. The existence of the connector 23 enables the guiding pipe 21 to be cleaned or replaced through this interface when necessary, so as to ensure the long-term operation of the system without being affected by pollutants. A dust-proof cap 24 is sleeved on the outer side of the connector 23. The dust-proof cap 24 is made of polyurethane, and this material has good wear resistance and corrosion resistance, which can effectively protect the connector 23 from external pollutants entering.

[0030] Working principle:

[0031] As Figure 1 - Figure 3 shown:

[0032] When in use: First, reinstall the air filter 15 above the conducting body 11. Then, the lower fuel injection pipe of the conducting body 11 is designed with a 45-degree inclined opening, making the fuel injection pipe enter smoothly below the liquid level, avoiding excessive bubbles or disturbing the liquid level during the refueling process, thus ensuring the smooth progress of refueling. In order to achieve flexible refueling operations, a fuel injection hose connector 23 is welded on the conducting body 11. When refueling operations are required, the fuel injection hose can be conveniently connected to the connector 23 to ensure the stable inflow of the oil fluid. When refueling operations are not carried out, the dust-proof cap 24 can be installed on the connector 23 to prevent dust and other pollutants from entering the system. The design material of the dust-proof cap 24 is durable polyurethane, which can provide long-term effective protection.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
