Description

Technical Field

[0001] This utility model relates to the field of lubricating oil processing technology, specifically a filtration device for lubricating oil processing. Background Technology

[0002] Lubricating oil is an oily liquid used to reduce friction and wear between two contacting surfaces. It is commonly used in various mechanical equipment, such as engines, gearboxes, and bearings, to ensure smooth operation and extend the service life of these devices. During the lubricating oil production process, filtration is crucial. Filtration effectively removes impurities mixed in during production, ensuring the purity of the lubricating oil, thereby extending its service life and giving it better lubricating properties. This results in more effectively reducing friction and wear, and improving equipment operating efficiency.

[0003] Patent CN222131206U discloses a filtration device for processing lubricating oil base oil, comprising: a base fixedly connected to the bottom of a housing; a top of the housing fixedly connected to a top cover; a motor and several feed pipes fixedly mounted on the top cover; the output end of the motor fixedly connected to a rotating rod; a first filter cylinder, a second filter cylinder, and a third filter cylinder fixedly mounted on the rotating rod from top to bottom; a first funnel, a second funnel, and a third funnel fixedly mounted on the inner wall of the housing from top to bottom; the first funnel being vertically positioned between the first and second funnels; the second funnel being vertically positioned between the second and third funnels; and the third funnel being vertically positioned below the third funnel. This method can improve the filtration effect on lubricating oil base oil.

[0004] Although the above-mentioned device improves the filtration effect of lubricating oil, it still has the following shortcomings:

[0005] The aforementioned device employs multiple filter cartridges and funnels for multi-layer filtration, which improves filtration efficiency. However, the filter cartridges and funnels are fixed within the device, requiring a complete shutdown and replacement of the entire system for maintenance, which is time-consuming and labor-intensive. This also limits the depth cleaning of the filter media. Furthermore, the fixed filter media combination cannot be flexibly increased, decreased, or its precision adjusted according to operating conditions, making it difficult to adapt to complex scenarios. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a filtration device for lubricating oil processing. By setting up a layered filter, the filtration accuracy and number of filtration cycles can be adjusted according to requirements.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for lubricating oil processing, comprising a base, on which an oil outlet chamber, a filter chamber, and a filling chamber of the same outer diameter are respectively arranged. Each chamber is fixed by a flange connection and a flange ring is provided at the connection. A sealing ring is provided at the connection of the chamber bodies. The filter chambers can be stacked. The filter chamber includes an annular outer shell. An oil receiving plate is provided on the top surface of the annular outer shell. A filter channel is provided vertically through the annular outer shell below the oil receiving plate. A filter bag is placed in the filter channel. The filter bag includes a placement ring and a multi-layer composite filter cloth bag.

[0008] Furthermore, four filter channels are provided on the annular outer shell and are symmetrically distributed along the axial direction.

[0009] Furthermore, the oil outlet chamber includes an oil outlet shell, the top surface of which has an inclined downward filter oil storage tank, and the bottom surface of the oil outlet shell is provided with an oil outlet pipe connected to the bottom surface of the filter oil storage tank.

[0010] Furthermore, the refueling tank includes a refueling shell, an oil pump is installed in the middle of the top surface of the outer side of the refueling shell, a refueling pipe is installed at the input end of the oil pump, an oil spray plate connected to the oil pump is installed on the top surface of the inner side of the refueling shell, an oil spray pipe corresponding to the center position of the filter channel is installed on the bottom surface of the oil spray plate, a pressure valve is installed on one side of the top surface of the refueling shell, a pressure relief valve is installed on the other side of the top surface of the refueling shell, and a pressure detector with a pressure probe extending into the interior of the refueling shell is installed on the outer side of the refueling shell.

[0011] Furthermore, an oil discharge pump is installed on the oil outlet pipe at the bottom of the oil outlet casing.

[0012] Furthermore, a heating pipe is connected in the middle of the refueling pipe, and a temperature controller is installed on the outside of the heating pipe.

[0013] Furthermore, the placement ring has an inverted L-shaped cross-section and its inner diameter is smaller than that of the multi-layer composite filter bag.

[0014] Furthermore, in the flange ring, the flange ring located above the connection has symmetrically arranged limit blocks on the inner side of its bottom surface, and the flange ring located below the connection has a limit groove corresponding to the position of the limit block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Filtration is achieved by setting up stackable filter chambers, allowing for multiple filtration cycles to improve the filtration effect. The selection of multi-layer composite filter bags with varying filtration precision enables flexible adjustment of the filtration accuracy to meet the requirements of different lubricating oils. Flange connections between chambers with sealing rings ensure a sealed environment during operation, preventing oil leakage. The pressure relief valves, in conjunction with the pressure-boosting valves, can also pressurize the internal components, accelerating the filtration process and increasing efficiency. A heating element and temperature controller maintain the lubricating oil between 40℃ and 60℃, ensuring optimal viscosity and allowing for smoother passage through the filter bags, further enhancing filtration speed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 5 As shown, a filtration device for lubricating oil processing includes a base 1, on which an oil outlet chamber 2, a filter chamber 3, and an oil filling chamber 4 of the same outer diameter are respectively arranged. The chambers are fixed by flange connection and a flange ring 5 is provided at the connection. A sealing ring 6 is provided at the connection of the chamber bodies. The filter chambers 3 can be stacked. The filter chamber 3 includes an annular shell 301. An oil receiving plate 302 is opened on the top surface of the annular shell 301. A filter channel 303 is opened through the oil receiving plate 302 from top to bottom. A filter bag 304 is placed in the filter channel 303. The filter bag 304 includes a placement ring 305 and a multi-layer composite filter cloth bag 306.

[0025] like Figure 1 As shown, the filtration device in this utility model is structurally similar to existing filtration devices. For example, patent CN222131206U discloses a filtration device for processing lubricating oil base oil. The main improvement of this utility model is that by setting a layered assembled filter, the filtration accuracy and filtration frequency can be adjusted according to requirements. Figures 1 to 5 As shown, this utility model discloses a filtration device for lubricating oil processing. In use, a sufficient number of filter chambers 3 are selected according to filtration requirements. Then, multi-layer composite filter bags 306 of different precision are arranged in order from coarse to fine and placed into the filter chambers 3 from top to bottom. The filter chambers 3, oil outlet chamber 2, and oil filling chamber 4 are then connected using bolts, nuts, and flange rings 5, completing the preparation work. Subsequently, under the pumping action of the oil pump 402, the lubricating oil to be filtered enters the spray plate 404 and, under the pressure of the pump, falls from the oil inlet nozzle 405 onto the oil receiving plate 302. Under the action of gravity, it enters the filter bags 304 for filtration. The lubricating oil that has passed through the first layer of filter bags 304 continues to fall. The lubricating oil falls sequentially into the lower filter bag 304. Before the lubricating oil is fed into the oil pump 402 by the oil filling pipe 403, the lubricating oil to be filtered is heated by the heating pipe 409, and with the cooperation of the temperature controller 410, its temperature is kept between 40℃ and 60℃, so that the viscosity of the lubricating oil is moderate and the filtration speed is improved. During the filtration process, with the cooperation of the pressure valve 406, the pressure relief valve 407 and the pressure detector 408, the internal pressure of the device can be appropriately increased, thereby accelerating the filtration speed and improving the filtration efficiency. Finally, the filtered lubricating oil falls into the filter oil storage tank 202 and is drawn out by the oil discharge pump 204 from the oil outlet pipe 203, completing the lubricating oil filtration process.

[0026] like Figure 4 As shown, four filter channels 303 are provided on the annular outer shell 301 and are symmetrically distributed along the axial direction.

[0027] Specifically, by setting up four filter channels 303 and symmetrically distributing them along the axial direction, the filtration efficiency can be improved. At the same time, the setting of multiple filter ports disperses the pressure generated by the liquid flow, avoiding damage to the filter bag 304 or failure of the seal due to pressure concentration in local areas.

[0028] like Figure 2 As shown, the oil outlet chamber 2 includes an oil outlet shell 201. The top surface of the oil outlet shell 201 is provided with an inclined downward filter oil storage tank 202, and the bottom surface of the oil outlet shell 201 is provided with an oil outlet pipe 203 connected to the bottom surface of the filter oil storage tank 202.

[0029] Specifically, after multiple filtrations, the filtered lubricating oil will fall into the filter oil storage tank 202 and be drawn out from the oil outlet pipe 203, completing the lubricating oil filtration process.

[0030] like Figure 3 As shown, the refueling tank 4 includes a refueling shell 401. An oil pump 402 is installed in the middle of the top surface of the outer side of the refueling shell 401. An oil pump 403 is installed at the input end of the oil pump 402. An oil spray plate 404 connected to the oil pump 402 is installed on the top surface of the inner side of the refueling shell 401. An oil spray pipe 405 corresponding to the center position of the filter channel 303 is installed on the bottom surface of the oil spray plate 404. A pressure valve 406 is installed on one side of the top surface of the refueling shell 401. A pressure relief valve 407 is installed on the other side of the top surface of the refueling shell 401. A pressure sensor 408 with a pressure probe extending into the interior of the refueling shell 401 is installed on the outer side of the refueling shell 401.

[0031] Specifically, under the pumping action of the oil pump 402, the lubricating oil to be filtered enters the oil spray plate 404 on the top surface inside the oil filling casing 401 through the oil filling pipe 403, and falls from the oil inlet spray pipe 405 under the pressure of the oil pump. It then falls onto the oil receiving plate 302 and enters the filter bag 304 for filtration. During the filtration process, the pressure valve 406 can pressurize the inside of the sealed device, thereby accelerating the filtration speed and improving the filtration efficiency. At the same time, with the cooperation of the pressure detector 408 and the pressure relief valve 407, the pressure of the device can be adjusted in a timely manner to ensure that the pressure inside the device is within a suitable range.

[0032] like Figure 2 As shown, an oil discharge pump 204 is installed on the oil outlet pipe 203 at the bottom of the oil outlet housing 201.

[0033] Specifically, by installing an oil discharge pump 204 on the oil outlet pipe 203, the filtered lubricating oil can be drawn out of the oil outlet chamber 2 more quickly, avoiding excessive storage of lubricating oil in the filter oil storage tank 202, which would affect the filtration efficiency.

[0034] like Figure 3As shown, a heating pipe 409 is connected in the middle of the refueling pipe 403, and a temperature controller 410 is installed on the outside of the heating pipe 409.

[0035] Specifically, the lubricating oil to be filtered is heated by setting a heating tube 409, and with the cooperation of a temperature controller 410, the temperature is kept between 40℃ and 60℃, so that the viscosity of the lubricating oil is moderate, allowing the lubricating oil to pass through the filter bag 304 more smoothly and improving the filtration speed.

[0036] like Figure 5 As shown, the placement ring 305 is an annular structure with an inverted L-shaped cross-section, and the inner diameter of the placement ring 305 is smaller than the inner diameter of the multi-layer composite filter bag 306.

[0037] Specifically, by selecting an inverted L-shaped annular structure as the placement ring 305, the filter bag 304 can be firmly placed on the filter channel 303. At the same time, by making the inner diameter of the placement ring 305 smaller than the inner diameter of the multi-layer composite filter cloth bag 306, it is convenient for staff to take the filter bag 304.

[0038] like Figure 3 and Figure 4 As shown, in the flange ring 5, the flange ring 5 located above the connection is symmetrically provided with limit blocks 501 on the inner side of the bottom surface, and the flange ring 5 located below the connection is provided with limit grooves 502 corresponding to the positions of the limit blocks 501.

[0039] Specifically, by setting a limit block 501 and opening a corresponding limit groove 502, the device will not be misaligned when assembled. The positions of the oil inlet nozzle 405 and the filter channel 303, and the filter channel 303 and the filter channel 303 are in one-to-one correspondence, so that the lubricating oil can fall accurately during the layer-by-layer filtration process, and avoid excessive lubricating oil falling onto the oil receiving plate 302, which would affect the filtration efficiency.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
