Description

Technical Field

[0001] The utility model relates to the technical field of metal drawing lubricating oil processing equipment, in particular to a drawing oil filtering and recovery device. Background Art

[0002] The metal drawing process uses a large amount of lubricating oil, which in turn produces a large amount of waste oil containing metal debris and metal microparticles. Currently, waste oil is usually filtered and reused to save resources. In the existing technology, waste oil is only filtered using filter cloth or filter screen. For example, CN215654032U discloses a lubricating oil filter device for an enameled wire drawing machine. The user first pours the lubricating oil to be filtered from the oil inlet pipe into the filter box, then turns on the servo motor to stir the lubricating oil. The lubricating oil is then filtered through the filter screen and then reaches the threaded conveyor rod, which conveys the filtered lubricating oil to the oil outlet pipe. Another example is CN117298707A discloses a multi-head drawing oil filter. Drawing oil containing copper powder flows to the surface of the filter cloth. A copper powder scraper scrapes off the copper powder attached to the filter cloth surface. The copper powder and the scraped drawing oil flow along the bottom of the copper powder scraper onto the surface of the copper powder filter plate, collecting the copper powder. However, the wire drawing waste oil contains small-particle metal powder, which is difficult to completely remove by only using filter cloth or filter mesh.

[0003] Enameled wire is commonly used in coil winding. The core wire's dimensional accuracy and surface smoothness significantly impact the coil's resistance. The purity of the lubricating oil used in the enameled wire drawing process also significantly affects the core wire's surface quality and dimensional accuracy. The recycled oil produced by the aforementioned waste drawing oil recycling device is insufficient to meet the requirements of the enameled wire drawing process. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The following combination Figures 1 to 4 , describing a drawing oil filtering and recovery device according to an embodiment of the present utility model.

[0032] The utility model discloses a drawing oil filtering and recovery device, comprising a first filtering mechanism 1, a second filtering mechanism 2, an oil storage tank 3, a filtering barrel 4 and a submersible pump 5. The first filtering mechanism 1 is provided with a detachable filter screen 11, and the second filtering mechanism 2 is provided with filter paper 21.

[0033] The first filter mechanism 1 , the second filter mechanism 2 and the oil storage tank 3 are arranged in sequence from top to bottom, the filter barrel 4 is sunk into the oil in the oil storage tank 3 , and the submersible pump 5 is located in the filter barrel 4 .

[0034] In the present invention, the first filter mechanism 1 filters the waste oil from wire drawing with a filter screen 11, followed by a second filter mechanism 2 filtering the waste oil with filter paper 21. The oil reservoir 3 stores and precipitates the waste oil after the two filtration processes. Because the submersible pump 5 is located within the filter barrel 4, the oil in the oil reservoir 3 is filtered again before reuse, significantly improving the purity of the recycled oil for wire drawing and meeting the core drawing process requirements for enameled wire. Furthermore, the detachable filter screen 11 and the ability to scrape the filter mud off the surface of the filter paper 21 facilitate mud recovery.

[0035] The wire drawing oil filtering and recovery device of the present invention is used for centrally processing waste oil generated by multiple drawing equipment. At the same time, based on the positional relationship of the first filtering mechanism 1, the second filtering mechanism 2 and the oil storage tank 3 arranged in sequence from top to bottom, the oil storage tank 3 can be designed as a pool sunk to the bottom, so that the oil storage tank 3 can have a larger oil storage space and lower equipment cost.

[0036] In one embodiment, the filter barrel 4 includes a cylindrical frame 41, with a filter interlayer disposed around and at the bottom of the cylindrical frame 41. The filter interlayer is filled with filter material 42, which is filter cotton. The filter cotton can absorb fine particles in the oil, further improving the purity of the oil. The filter cotton has a large number of pores, which provides low resistance to the oil, allowing the oil to quickly enter the filter barrel 4 and facilitate extraction by the submersible pump 5. The filter material 42 is preferably filter cotton.

[0037] Preferably, a hook 43 is provided on the top of the cylindrical frame 41, a hanging rod 31 is provided on the top of the oil storage tank 3, and the filter barrel 4 is hung on the hanging rod 31 through the hook 43, which facilitates the operation of the submersible pump 5 and the removal of the filter barrel 4 to replace the filter material 42 therein.

[0038] In an optional embodiment of the present invention, the bottom of the oil reservoir 3 is provided with a horizontal surface 32 and an inclined surface 33. One end of the horizontal surface 32 is connected to the side wall of the oil reservoir 3, and the other end is connected to the top of the inclined surface 33. The lower end of the inclined surface 33 extends to the end of the oil reservoir 3 facing away from the horizontal surface 32. The provision of the inclined surface 33 allows impurities in the oil to settle at one end of the oil reservoir 3. The filter barrel 4 is located on the horizontal surface 32, further improving the cleanliness of the recycled oil.

[0039] Preferably, a drain pipe 34 is connected to the bottom of the end of the oil reservoir 3 facing away from the horizontal surface 32, with the outlet of the drain pipe 34 located at the top of the first filter mechanism 1. The drain pipe 34 can drain oil containing a large amount of impurities and transport the oil to the first filter mechanism 1 for further filtration, thereby improving the reuse rate of waste wire drawing oil. It is understood that the drain pipe 34 is equipped with an oil pump.

[0040] In one embodiment of the present invention, the second filter mechanism 2 includes a filter tank 22, a filter mud collection tank 23, a filter paper unwinding mechanism 24, and a filter paper rewinding mechanism 25. The filter mud collection tank 23 is disposed on the inner wall of the filter tank 22. After extending from the filter paper unwinding mechanism 24, the filter paper 21 passes through the bottom of the first filter mechanism 1 and the filter mud collection tank in sequence, and is then wound around the filter paper rewinding mechanism 25. The filter mud collection tank 23 is provided with a scraper 26 for scraping the filter mud from the surface of the filter paper 21. The filter paper unwinding mechanism 24 and the filter paper rewinding mechanism 25 facilitate timely replacement of the filter paper 21 below the first filter mechanism 1, ensuring the filtering effect of the filter paper 21. Specifically, the first filter mechanism 1 includes a cylindrical filter seat, and the filter screen 11 disperses the oil, allowing the waste oil from the wire drawing process to fall more evenly onto the filter paper 21, thereby improving the filtering effect.

[0041] Preferably, the filter paper unwinding mechanism 24 is located at one end of the top of the filter tank 22, and the filter paper winding mechanism 25 is located on the side of the other end of the filter tank 22; a first guide roller 201 is provided on the top of the filter tank 22, and a second guide roller 202 and a third guide roller 203 are provided on the side of the filter mud collection tank 23, and the filter paper 21 passes around the first guide roller 201, the second guide roller 202 and the third guide roller 203 in sequence;

[0042] The filter paper 21 supported by the first guide roller 201 and the second guide roller 202 is located below the first filtering mechanism 1 , the third guide roller 203 is located below the second guide roller, and the bottom of the filter mud collection tank 23 has space for the filter paper 21 to pass through.

[0043] Based on the positional arrangement of the filter paper rewinding mechanism 25 and the filter paper unwinding mechanism 24, the filter paper 21 is scraped and rewound immediately after use, and the three guide rollers guide the movement of the filter paper 21. Specifically, the scraper 26 corresponds to the position of the second guide roller.

[0044] In an optional embodiment of the present invention, the bottom of the filter tank 22 is funnel-shaped and connected to a liquid outlet pipe 27. The liquid outlet pipe 27 extends into the oil reservoir 3, with the outlet end of the liquid outlet pipe 27 corresponding to the lower end of the inclined surface 33. An inclined buffer plate 35 is provided within the oil reservoir 3, with the lower end of the buffer plate 35 located below the liquid outlet pipe 27. The buffer plate 35 cushions the oil falling into the oil reservoir 3, preventing impurity particles that have settled at the bottom of the oil reservoir 3 from floating up. Exemplarily, the liquid outlet pipe 27 is a flat tube with a rectangular or elliptical cross-section.
