[0028] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0029] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.
[0030] As Figure 1 and Figure 2 shown, the pre-filter device of the oil filling machine of the present utility model design includes a filter tank body 1, and an oil inlet and an oil outlet are respectively reserved on the filter tank body 1; a replaceable cartridge filter element 2 is installed in the filter tank body 1; an oil inlet pipe 3 communicating with the inlet of the cartridge filter element 2 is provided at the oil inlet of the filter tank body 1; an oil discharge pipe 4 for connecting the oil filling machine is provided at the oil outlet of the filter tank body 1.
[0031] As an implementation manner, a detachable maintenance cover 5 is installed on the top of the filter tank body 1. The detachable property of the maintenance cover 5 enables the user to easily open and close the top of the tank body, thus facilitating the inspection, cleaning, and maintenance work inside the tank body. Especially when it is necessary to replace the cartridge filter element 2 or handle other internal faults, the presence of the maintenance cover 5 greatly simplifies the operation process.
[0032] Specifically, the cartridge filter element 2 includes:
[0033] A core seat 2.1 fixed to the oil inlet pipe 3;
[0034] A cross bracket 2.2 disposed at the center of the core seat 2.1; provides a stable support structure for the filter element 2.3. This design helps to prevent the filter element from being displaced or deformed due to the impact of the oil flow during the filtration process;
[0035] A filter element 2.3 installed on the core seat 2.1;
[0036] A fixing screw 2.4 straddling the cross bracket 2.2 and passing through the filter element 2.3;
[0037] A nut 2.5 installed on the fixing screw 2.4 and locking the filter element 2.3.
[0038] When the oil product enters the filter element 2.3 through the oil inlet pipe 3, the filter media inside the filter element, such as filter screens and filter papers, will intercept impurities, particulate matters, etc. in the oil product, and only allow the clean oil product to pass through. The fastening effect of the fixing screw 2.4 and the nut 2.5 ensures the integrity of the filter element during the filtration process, preventing damage or detachment of the filter media; since the filter element 2.3 is fixed on the cross bracket 2.2 through the fixing screw 2.4 and the nut 2.5, when the filter element needs to be replaced, the nut can be easily loosened, the filter element can be removed and replaced. This design improves the maintainability of the equipment and reduces the maintenance cost.
[0039] In addition, a clamping block 5.1 is reserved on the outer side of the inspection cover 5, and a clamping seat 1.1 adapted to the clamping block 5.1 is also provided on the filter tank body 1; the inspection cover 5 is clamped into the clamping seat 1.1 through the clamping block 5.1. This design enables users to simply operate the clamping block to open or close the inspection cover when needed, without the need to use additional tools or complex steps.
[0040] As an implementation manner, an oil pump 6 is installed at the inlet of the oil inlet pipe 3; through the drive of the oil pump, the oil product can overcome the pipeline resistance and pass through the filter element at a certain flow rate and pressure, so as to realize the filtration process.
[0041] A plurality of pressure relief pipes 7 communicated with the inner cavity of the filter tank body 1 are also installed outside the filter tank body 1; when the internal pressure of the system exceeds the set value, part of the oil product or gas is allowed to be discharged from the tank body to reduce the system pressure and protect the safety of the equipment.
[0042] A pressure valve 8 is also provided on the filter tank body 1; when the system pressure exceeds the set value, the pressure valve will automatically open to release part of the pressure; when the pressure drops below the set value, the pressure valve will close.
[0043] An emptying pipe 9 is installed at the bottom of the filter tank body 1, and when the system needs to be maintained or cleaned, all the oil product in the tank body is discharged to facilitate subsequent operations.
[0044] The working principle of the present utility model is as follows:
[0045] Structural composition: The device is mainly composed of a filter tank body 1, and an oil inlet and an oil outlet are provided on the tank body, which are respectively used for receiving the oil product to be filtered and outputting the filtered oil product. Inside the tank body, a replaceable cylindrical filter element 2 is installed, which is the core component for realizing the filtration function.
[0046] Filtration process:
[0047] Oil product entry: The oil product to be filtered enters the filter tank body 1 through the oil inlet, and then is guided to the inlet of the cylindrical filter element 2 through the oil inlet pipe 3.
[0048] Filtration function: When the oil passes through the cartridge filter element 2, the filter media inside the filter element, such as filter screens and filter papers, will intercept impurities, particulate matters, etc. in the oil, and only allow clean oil to pass through. This process effectively removes most of the pollutants in the oil.
[0049] Oil discharge: The clean oil filtered by the filter element flows out from the outlet of the filter element, passes through the oil discharge port of the filter tank 1, and finally is connected to an oil filling machine or other subsequent equipment through the oil discharge pipe 4 for use.
[0050] Maintainability: Since the cartridge filter element 2 is replaceable, when the filter element is blocked or the filtration effect decreases due to long-term use, it can be conveniently taken out and replaced with a new filter element, thus ensuring the continuous and effective operation of the filtration device.
[0051] It should be noted that in this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Unless otherwise expressly stipulated and defined, the terms "install", "connect" and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
