Description

Technical Field

[0001] This utility model relates to the technical field of dual-cylinder lubricating oil filters, and in particular to a multi-stage filtration dual-cylinder lubricating oil filter. Background Technology

[0002] The dual-cylinder filter, also known as a dual-cylinder return line filter, consists of two single-cylinder filters and a two-position six-way reversing valve. It has a simple structure, is easy to use, and is equipped with a bypass valve and a filter element contamination and blockage indicator to ensure system safety.

[0003] Existing dual lubricating oil filters are generally designed as separate units, with the filter and three-way valve connected by a flange. If the connection is not proper, oil leakage is likely to occur. Because the space is very small, once an oil leak occurs, it is extremely difficult to deal with. The filter inlet and outlet are generally designed at the bottom, resulting in a small filtration area that is prone to clogging. The switching cycle is also short. The filter element is generally supported by the outlet pipe, which has a small support area. If it is tilted, it is very easy to leak oil.

[0004] An existing patent (publication number: CN216023477U) discloses an integrated online switching dual-cylinder lubricating oil filter for steam turbines, belonging to the technical field of steam turbine lubricating oil filtration devices. The integrated online switching dual-cylinder lubricating oil filter for steam turbines includes a filter cylinder, an inlet three-way valve, an outlet three-way valve, a filter element, and a filter element cap. The bottom and top of the filter cylinder are respectively provided with a filter inlet and a filter outlet. An inlet three-way valve and an outlet three-way valve are respectively provided on the filter inlet and outlet. The housings of the inlet and outlet three-way valves are connected to the filter cylinder as an integral structure. The filter element is directly fixed to the bottom of the filter cylinder through the filter element cap. This utility model prevents oil leakage, has a small footprint, and the filter inlet and outlet are respectively located at the bottom and top of the filter cylinder, resulting in a large filtration area, making it less prone to clogging and allowing for long operating time. The filter element is directly fixed to the bottom of the filter cylinder through the filter element cap, ensuring a large contact area and preventing leakage.

[0005] To address the aforementioned problems, existing patents offer solutions. Most existing dual-cylinder lubricating oil filters rely on a single filter element for filtration, resulting in poor filtration efficiency. Furthermore, because both large and micro-particles in the lubricating oil are filtered by the filter element, frequent replacements are necessary, increasing operating costs. Additionally, the use of dual-cylinder lubricating oil filters often requires manual inspection to check for blockages. However, it's impossible to constantly monitor the oil flow rate at the filter outlet, making it difficult to detect blockages promptly.

[0006] Therefore, a multi-stage dual-cylinder lubricating oil filter is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a multi-stage dual-cylinder lubricating oil filter, which solves the problems of existing dual-cylinder lubricating oil filters, most of which only have a single filter element installed for operation to filter the lubricating oil, resulting in poor filtration effect. Furthermore, since both large and micro impurities in the lubricating oil are filtered by the filter element, frequent filter element replacement is required, which increases operating costs. In addition, during the use of dual-cylinder lubricating oil filters, it is mostly necessary to manually observe and judge whether there is blockage inside. However, it is impossible for a person to constantly observe the oil output rate of the dual-cylinder lubricating oil filter outlet, thus making it impossible to detect blockage in time.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 The present invention provides the following technical solution:

[0031] A multi-stage dual-cylinder lubricating oil filter includes a control component 1, a filter component 2, a base 3, a reversing valve body 4, an inlet pipe 5, an outlet pipe 6, a support sleeve 7, a connecting pipe 8, a cylinder seat 9, a cylinder body 10, and a cylinder cover 11. The control component 1 is located on the front side of the reversing valve body 4, the filter component 2 is located inside the cylinder body 10, the reversing valve body 4 is fixedly connected to the top of the base 3, the inlet pipe 5 and the outlet pipe 6 are both fixedly connected to the front side of the reversing valve body 4, the support sleeve 7 and the connecting pipe 8 are both fixedly connected to both sides of the reversing valve body 4, the cylinder seat 9 is fixedly connected to the top of the connecting pipe 8, the cylinder body 10 is fixedly connected to the top of the cylinder seat 9, and the cylinder cover 11 is threadedly connected to the top of the cylinder body 10.

[0032] The control assembly 1 includes an electric valve 101, an alarm 102, a control button 103, and a pressure sensor 104. The electric valve 101 is fixedly connected to the top of the reversing valve body 4, the alarm 102 is fixedly connected to the front side of the reversing valve body 4, the control button 103 is fixedly connected to the right side of the alarm 102, and the pressure sensor 104 is fixedly connected to the inner wall of the reversing valve body 4.

[0033] In this embodiment: By setting the control component 1, the control component 1 can monitor in real time the pressure generated when the lubricating oil is discharged. When blockage occurs inside the cylinder 10, the pressure will decrease. After the pressure decreases to a certain level, an alarm signal will be issued, prompting the operator to replace the filter element 209 inside the cylinder 10. By setting the filter component 2, which adopts a multi-layer filtration structure, the workload of the filter element 209 is reduced, thereby reducing the replacement frequency of the filter element 209 and reducing operating costs. By setting the electric valve 101, which is an existing electric device controlling the reversing valve body 4, and by setting the alarm 102, the alarm 10... 2 is connected to pressure sensor 104, so that when pressure sensor 104 senses that the pressure is less than a certain level, it will send a command to alarm 102, so that alarm 102 will emit light and sound alarm signals to remind staff to replace filter element 209. At the same time as sending a command to alarm 102, pressure sensor 104 will also send a command to electric valve 101, so that electric valve 101 will open and close the blocked side of cylinder 201. Through the setting of control button 103, control button 103 can open and close alarm 102. The cylinder cover 11 is the existing cylinder cover 11 of dual cylinder lubricating oil filter with exhaust screw plug. The bottom of connecting pipe 8 is provided with drain port.

[0036] Specifically, such as Figure 4 As shown, the surface of the locking block 207 is fitted with the mounting block 208, and the bottom of the mounting block 208 is fixedly connected with the filter element 209.

[0037] In this embodiment: the cylinder 201 prevents lubricating oil from directly contacting the filter element 209, allowing the lubricating oil to rise and be filtered from top to bottom. The connecting cylinder 202 connects to the top of the cylinder 201. The filter plate 203 performs initial filtration of the lubricating oil, filtering out large particles. The filter cylinder 204 performs secondary filtration of the lubricating oil. By setting the limiting block 205, the limiting block 205 can achieve the effect of limiting the sliding connection of the connecting cylinder 202. By setting the handle 206, the handle 206 can facilitate the removal of the filter cylinder 204 for cleaning. By setting the locking block 207, the locking block 207 can achieve the effect of locking the mounting block 208. By setting the mounting block 208, the mounting block 208 can achieve the effect of connecting the filter element 209. By setting the filter element 209, the filter element 209 is a special filter element 209 for existing dual-cylinder lubricating oil filters.

[0038] Specifically, such as Figure 3 As shown, a mounting hole 12 is provided on the front side of the reversing valve body 4, and the inner wall of the mounting hole 12 is fixedly connected to the surface of the pressure sensor 104.

[0039] Specifically, such as Figure 4 As shown, sliding grooves 13 are provided on both sides inside the connecting cylinder 202, and the inner wall of the sliding groove 13 is slidably connected to the surface of the limiting block 205.

[0040] In this embodiment: the mounting hole 12 can be used to connect and fix the pressure sensor 104, and the sliding groove 13 can be used to limit the sliding connection of the limiting block 205.

[0041] Specifically, such as Figure 5 As shown, the top of the mounting block 208 is provided with a slot 14, and the inner wall of the slot 14 is engaged with the surface of the mounting block 207.

[0042] Specifically, such as Figure 5 As shown, a grid limiting plate 15 is fixedly connected to the surface of the mounting block 208, and the surface of the grid limiting plate 15 is in contact with the inner wall of the cylinder 201.

[0043] In this embodiment: the slot 14 can be used to engage the card block 207, and the mesh limiting plate 15 can be used to limit the installation block 208, thereby facilitating the installation of the filter element 209.

[0044] Specifically, such as Figure 5As shown, a connecting groove 16 is provided on the top of the cylinder base 9, and the inner wall of the connecting groove 16 is engaged with the bottom of the filter element 209.

[0045] Specifically, such as Figure 6 As shown, a sealing groove 17 is provided at the top of the cylinder body 10, and a sealing gasket 18 is engaged with the inner wall of the sealing groove 17. The top of the sealing gasket 18 is engaged with the top of the inside of the cylinder cover 11.

[0046] In this embodiment: the connecting groove 16 can connect the filter element 209, and the sealing groove 17 can connect the sealing gasket 18. Thus, when used with the sealing gasket 18, the connection between the cylinder cover 11 and the cylinder body 10 can be sealed.

[0047] Working principle: First, connect the pipeline for conveying lubricating oil to the inlet pipe 5, and then connect the oil discharge pipe to the outlet pipe 6. Lubricating oil can then be conveyed from the inlet pipe 5. After entering the device, the lubricating oil flows into the cylinder 10, then flows upwards through the obstruction of the cylinder 201, and then passes through the filter plate 203. The filter plate 203 filters out large impurities inside the lubricating oil. After passing through the filter plate 203, the oil enters the filter cylinder 204 from the top, undergoes secondary filtration in the filter cylinder 204, and then enters the cylinder 201. It then undergoes a third filtration through the filter element 209, and finally exits through the cylinder... The lubricating oil is discharged through the outlet pipe 6 via the seat 9 and connecting pipe 8. If the filter element 209 becomes clogged, the discharge volume of lubricating oil will decrease, thereby reducing the pressure. This is then sensed by the pressure sensor 104. When the pressure drops to a certain level, the pressure sensor 104 will send the data to the alarm, causing the alarm to activate and issue an alarm to prompt the staff to replace the filter element 209. At the same time, it will also send a command to the electric valve 101, causing the electric valve 101 to operate, thereby closing the clogged side of the cylinder 10 and opening the other side of the cylinder 10. Then, the filter element 209 inside the closed cylinder 10 can be replaced.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
