Description

Technical Field

[0001] This utility model relates to the field of filtration devices, and more specifically to a filtration device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.

[0003] Filtration devices typically use filter plates to filter impurities in lubricating oil. Over time, these filter plates can become clogged. Current methods for cleaning filter plates involve disassembling and washing them. However, this disassembly and cleaning method inevitably affects the normal operation of the filtration device and reduces its efficiency.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem in the prior art where the removal and cleaning of the filter plate affects the normal use of the filtration device, this utility model provides a filtration device for lubricating oil production. The filtration device includes: a tank body, in which a filter plate is installed; filter holes are formed on the filter plate, and a collection box is provided on the outer circumferential side of the filter plate; a cleaning structure, including a rotatable mounting rod installed below the filter plate, a rotating rod that drives the mounting rod to rotate, a drive motor that drives the rotating rod to rotate, a sleeve mounted on the mounting rod, and a telescopically mounted top column on the sleeve and matching the filter holes; the top column has a guide slope that abuts against the filter plate, and a compression spring that abuts against the top column is provided inside the sleeve.

[0006] This utility model discloses a filtration device for lubricating oil production, comprising a tank, a filter plate, and a cleaning structure. The cleaning structure includes an mounting rod, a rotating rod, a drive motor, a sleeve, and a top column. The drive motor is connected to the rotating rod and drives it to rotate; the rotating rod is connected to the mounting rod and drives it to rotate; the sleeve is mounted on the mounting rod, and the top column is mounted on the sleeve, with the top column matching the filter hole. When the top column rotates to the filter hole, it pushes out impurities from the filter hole, preventing clogging. A guide slope is formed on the top column, and a compression spring is installed inside the sleeve to abut against the top column, facilitating the top column's disengagement from the filter hole, retraction into the sleeve, and subsequent push-out at the next filter hole for cleaning. Through these features, this utility model's filtration device for lubricating oil production, driven by the drive motor, can drive the mounting rod to rotate, and when the top column rotates to the filter hole, push out impurities from the filter hole, preventing clogging. This eliminates the need to disassemble and clean the filter plate, improving the efficiency of the filtration device.

[0007] Furthermore, the top post includes a telescopic portion that mates with the sleeve, and an ejector portion disposed at one end of the telescopic portion away from the sleeve; the guide slope is formed on the ejector portion, and the diameter of the telescopic portion is larger than the diameter of the filter hole.

[0008] Furthermore, a limiting plate is provided inside the sleeve, and the two ends of the compression spring are respectively connected to the limiting plate and the telescopic part.

[0009] Furthermore, a connecting seat is provided between the sleeve and the mounting rod; the connecting seat is sleeved on the circumferential outer side of the mounting rod and is fixedly connected to the mounting rod by bolts.

[0010] Furthermore, a limiting ring is rotatably arranged inside the tank, and both ends of the mounting rod are disposed on the limiting ring; a limiting groove matching the limiting ring is provided on the tank.

[0011] Furthermore, the limiting ring and the mounting rod are fixedly connected by bolts.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The installation rod is driven by a motor to rotate. When the top column rotates to the filter hole, it pushes out the debris in the filter hole to prevent the filter hole from clogging. This eliminates the need to disassemble and clean the filter plate, thus improving the efficiency of the filtration device. A guide slope is formed on the top column, and a compression spring is installed in the sleeve to abut against the top column. This allows the top column to easily disengage from the filter hole, retract into the sleeve, and be pushed out at the next filter hole for cleaning. Attached Figure Description

The collection box 15 is roughly circular and is arranged on the outer circumference of the filter plate 13. Impurities on the filter plate 13 flow into the collection box 15 under the impact of the lubricating oil.

[0024] Figure 2 yes Figure 1 An enlarged view of point A in the middle. (See diagram below.) Figure 1 and Figure 2As shown, the cleaning structure 2 includes a drive motor 21 mounted on the top of the tank 1, a rotating rod 22 connected to the drive motor 21, a mounting rod 23 connected to the rotating rod 22, a sleeve 24 mounted on the mounting rod 23, and a telescopic top column 25 mounted on the sleeve 24. The motor shaft of the drive motor 21, the rotating rod 22, and the central axis of the filter plate 13 are collinear. The rotating rod 22 extends into the tank 1 and passes through the filter plate 13, extending below the filter plate 13. Furthermore, the mounting rod 23 is located at the end of the rotating rod 22 away from the drive motor 21. Specifically, a limiting ring 16 is rotatably arranged inside the tank 1, and a limiting groove matching the limiting ring 16 is formed inside the tank 1. The limiting ring 16 is rotatably arranged within the limiting groove. Both ends of the mounting rod 23 are mounted on the limiting ring 16. Furthermore, a mounting seat is provided on the limiting ring 16, and a mounting groove matching the mounting rod 23 is formed on the mounting seat. Specifically, a connecting hole is provided on the mounting rod 23, and a bolt is provided on the mounting base. The bolt passes through the connecting hole on the mounting base and the mounting rod 23, so that the limiting ring 16 and the mounting rod 23 form a fixed connection.

[0025] See also Figure 1 and Figure 2 The sleeve 24 is detachably mounted on the mounting rod 23. In one or more embodiments, the sleeve 24 is generally cylindrical, and a connecting seat 26 is provided at the bottom of the sleeve 24, which is sleeved on the circumferential outer side of the mounting rod 23. Specifically, bolt holes are provided on the connecting seat 26 and the mounting rod 23, and bolts are provided in the bolt holes. The bolts pass through the bolt holes on the connecting seat 26 and the mounting rod 23, so that the connecting seat 26 and the mounting rod 23 form a fixed connection. Based on Figure 1As shown, the bolts are located on the inner and outer sides of the sleeve 24. Further, a row of sleeves 24 is arranged along the length of the mounting rod 23, gradually increasing in length from both sides towards the center. A compression spring 27 and a limiting plate 241 abutting against the compression spring 27 are provided inside the sleeve 24. The limiting plate 241 is located at the bottom of the compression spring 27, ensuring that each compression spring 27 has the same length. Further, the top post 25 includes a telescopic portion 251 that mates with the sleeve 24, and an ejector portion 252 disposed at the end of the telescopic portion 251 away from the sleeve 24. One end of the telescopic portion 251 extends into the sleeve 24, and a baffle 253 is provided at that end. The two ends of the compression spring 27 abut against the baffle 253 and the limiting plate 241, respectively. Further, a guide ramp 254 is formed on the ejector portion 252. Specifically, the ejector portion 252 is approximately frustum-shaped, with a thicker end near the telescopic portion 251 and a thinner end away from the telescopic portion 251. The diameter of the thicker end of the ejector portion 252 is smaller than the diameter of the filter hole, allowing the ejector portion 252 to penetrate deep into and pass through the filter hole, thereby ejecting impurities from the filter hole. The diameter of the telescopic portion 251 is larger than the diameter of the filter hole, thus preventing the telescopic portion 251 from extending into the filter hole. Furthermore, a telescopic post is provided between the top post 25 and the limiting plate 241, and a compression spring 27 is sleeved on the circumferential outer side of the telescopic post.

[0026] The working principle of this utility model is as follows:

[0027] The drive motor 21 drives the rotating rod 22 to rotate, which in turn drives the mounting rod 23 to rotate. When the top column 25 rotates to the filter hole, it pushes out the debris in the filter hole, and the lubricating oil washes the pushed-out debris into the collection box 15. The drive motor 21 continues to drive the mounting rod 23 to rotate, the guide slope 254 abuts against the filter plate 13, and the top column 25 retracts into the sleeve 24 until it rotates to the next filter hole. The compression spring 27 drives the top column 25 to extend out of the sleeve 24 and push out the debris in the filter hole.

[0028] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the protection scope of this utility model.
