[0021] 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.

[0022] This utility model provides two technical solutions, specifically including the following embodiments:

[0023] Example 1

[0024] Please see Figure 1-Figure 2 A filter for impurities in lubricating oil production includes a filter cylinder 1, with a filter screen 2 inside the filter cylinder 1. The filter screen 2 can filter impurities in the lubricating oil and improve the quality of the lubricating oil. The filter cylinder 1 is equipped with an automated accelerated filtration mechanism 3 that punctures the oil film generated when the filter screen 2 filters the lubricating oil.

[0025] The automated accelerated filtration mechanism 3 includes a U-shaped plate 31 fixed between the two sides of the filter cylinder 1. A cylinder 32 is fixed to the top of the U-shaped plate 31. The output end of the cylinder 32 passes through the U-shaped plate 31 and extends to the bottom of the U-shaped plate 31. A circular plate 33 is fixed to the output end of the cylinder 32. Multiple needles 34 are fixed to the bottom of the circular plate 33. The bottom ends of the multiple needles 34 all penetrate the filter holes on the filter screen 2. By setting up the automated accelerated filtration mechanism 3, the downward movement of the needles 34 punctures the oil film in the filter holes of the filter screen 2, so that the lubricating oil can be filtered faster, greatly improving the filtration efficiency. It has a high degree of automation and is very practical.

[0026] Four fixing blocks 4 are fixed on the inner wall of the filter cylinder 1, and the filter screen 2 is placed on top of the four fixing blocks 4. The outer surface of the filter screen 2 is slidably connected to the inner surface of the filter cylinder 1.

[0027] One side of the filter cartridge 1 is connected to an oil outlet pipe 6, and a valve 7 is installed on the oil outlet pipe 6. The valve 7 is an electric butterfly valve. After opening the valve 7, the filtered lubricating oil can be discharged from the oil outlet pipe 6.

[0028] Cylinder 32 is controlled by an external switch and is electrically connected to an external power source.

[0029] Example 2

[0030] Based on Example 1, see Figures 3-4 As shown, a locking assembly 5 is provided on the top of the filter screen 2. The locking assembly 5 includes two vertical rods 51 fixed to the top of the filter screen 2.

[0031] The top ends of both vertical rods 51 extend to the outside of the filter cylinder 1, and the top ends of both vertical rods 51 are rotatably connected to the limiting plate 52.

[0032] The bottoms of both limiting plates 52 are in contact with the top of the circular plate 33. With the locking assembly 5, when the filter screen 2 needs to be removed for cleaning, the two limiting plates 52 are rotated, and the circular plate 33 is raised, which drives the limiting plates 52, the vertical rod 51 and the filter screen 2 to rise synchronously, so that the filter screen 2 can be removed quickly and easily.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, lubricating oil is poured into filter cylinder 1, and filter screen 2 is used to filter impurities in the oil. Then, cylinder 32 is activated, causing cylinder 32 to move the circular plate 33 and the piercing needle 34 downwards. The piercing needle 34 punctures the oil film in the filter holes of filter screen 2, accelerating the filtration of lubricating oil. When filter screen 2 needs to be removed for cleaning, the two limit plates 52 are rotated to close cylinder 32, causing cylinder 32 to move the circular plate 33 upwards. At the same time, the circular plate 33 moves the limit plate 52, the vertical rod 51, and filter screen 2 upwards, finally lifting filter screen 2. The limit plate 52 is then rotated again to reset, and filter screen 2 can be removed for cleaning.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
